The present disclosure relates to the field of printing technology and, more particularly, relates to a force receiving part and a toner cartridge.
A toner cartridge is a replaceable consumable which is widely used in the field of electronic image forming. The toner cartridge is used in an image forming device to provide developer to the image forming device. The image forming device is a device which forms images on a recording material by an electrophotographic imaging processing technique, and may include, for example, an electrophotographic copier, a laser printer, an electrophotographic printer, a facsimile machine, and a word processor, and the like.
The existing toner cartridge may mainly include a cartridge body and a force receiving part. A large amount of developer is contained in the cartridge body having a column-structure. The force receiving part, which is connected to the cartridge body, may be disposed on a sidewall at one end of the cartridge body along the length direction. The force receiving part may receive a rotational driving force from the image forming device and then the rotational driving force may be transmitted to other parts of the toner cartridge, such that the toner cartridge may discharge the developer outwardly. The toner outlet, for discharging the developer, of the toner cartridge may be configured at or near the force receiving part.
The connecting portion between the existing image forming device and the toner cartridge may be a rotational driving force transmission part of the image forming device. A special structure may be disposed at the rotational driving force transmission part. A needle-like component may be at the center of the rotational driving force transmission part and may be coplanar with the opening of the rotational driving force transmission part. When the toner cartridge is installed on the image forming device, the rotational driving force transmission part may move along the direction toward the toner cartridge, and the needle-like component of the rotational driving force transmission part may deeply enter the inside of the force receiving part accordingly. Then, a pushing component around the inner wall of the rotational driving force transmission part may retract along the direction away from the toner cartridge, and then the image forming device may drag the toner cartridge to move along the direction away from the rotational driving force transmission part, such that the outlet on the toner cartridge may be opened and the developer may be discharged from the toner cartridge. When the image forming operation of the image forming device stops and the toner cartridge is uninstalled from the image forming device, the image forming device may drag the toner cartridge to move along the direction toward to the rotational driving force transmission part to close the outlet on the toner cartridge; the pushing component around the inner wall of the rotational driving force transmission part may push along the direction toward the toner cartridge; the rotational driving force transmission part may move along the direction away from the toner cartridge; and at this point, the toner cartridge may be removed. Due to poor structure design, non-proper use, unqualified production materials and the like of the existing toner cartridge, it may result in that the driving tooth structure in the existing toner cartridge may be locked with the internal engagement position of the image forming device, and the operation of the image forming device may have errors; it may also result in that the toner cartridge may have poor sealing, causing the developer in the toner cartridge to be leaked out to pollute the environment and affect image forming quality; and it may further result in that the rotational driving force transmission part may not be engaged with the force receiving part or may be easily disengaged after the engagement.
The present disclosure provides a force receiving part and a toner cartridge, which may prevent the toner cartridge from leaking the developer stored in the toner cartridge during transportation and movement to cause environmental pollution.

A force receiving part is provided in one embodiment. Referring to
As shown in
A receiving tooth 123, a support rod 124, a transmission rod 125, an anti-detachment trench 126, a first locking tooth 122, and a second locking tooth 121 may be disposed at the receiving element 120, where the receiving tooth 123 may receive the rotational driving force from the image forming device; the support rod 124 may be elastic and inwardly deviated along the radial direction of the rotating axis of the toner cartridge body; the transmission rod 125 may be abutted against the protruding block 132, such that the rotational driving force is transmitted from the receiving element 120 to the transmission element 130, and further to the toner cartridge body; and the first locking tooth 122 and the second locking tooth 121 may be used to prevent the receiving element 120 from detaching from the transmission element 130. When the toner cartridge works normally in the image forming device, the first locking tooth 122 may be just abutted against the protruding eave 131 or the first locking tooth 122 has not be abutted against the protruding eave 131. The second locking tooth 121, a backup measure, may be used as a safety measure when the first locking tooth 122 breaks or the first locking tooth 122 is pulled out of the position, where the first locking tooth 122 is abutted against the protruding eave, with the receiving element 120; at this point, the second locking tooth 121 may be abutted against the protruding eave, preventing the entire receiving element 120 from being pulled out of the transmission element 130. Optionally, in order to ensure that the receiving element 120 and the transmission element 130 are separated smoothly, the first locking tooth 122 and the second locking tooth 121 may not interfere with other portions of the transmission element 130. Once a malfunction, that is, the entire receiving element 120 is pulled out of the transmission element 130, occurs in the image forming device, it may not only affect the current print quality, but also damage the inside of the image forming device, Meanwhile, if the damaged toner cartridge is not properly handled, it may also affect the health of users and even pollute air and water sources.
An abutting portion 111 and a pushing element 112 may be disposed at the moving element 110. The abutting portion 111 may be abutted against the image forming device to move the moving element 110 along the direction of the rotating axis of the toner cartridge. The height of the abutting portion 111 protruding along the radial direction of the rotating axis of the toner cartridge may be greater than the height of the receiving tooth 123 protruding along the radial direction of the rotating axis of the toner cartridge. The pushing element 112 may enter the anti-detachment trench 126. When the pushing element 112 is in the anti-detachment trench 126, due to the existence of the moving element 110, the support rod 124 may not be deviated inwardly along the radial direction of the rotating axis of the toner cartridge body.
A first elastic element 150 may be disposed between the first moving element 110 and the receiving element 120. Optionally, the first elastic element 150 may be a spring. The moving position of the moving element 110 may be restricted by the receiving element 120.
The process of installing the toner cartridge into the image forming device is described in detail hereinafter. A moving part 998 on the image forming device may be located inside the rotational driving force transmission part 999.
In the first step, as shown in
In the second step, after the toner cartridge is installed in the image forming device, since the radial distance between the abutting portion 111 and the rotating axis of the toner cartridge body is greater than the radial distance between the receiving tooth 123 and the rotating axis of the toner cartridge body, the moving part 998 of the image forming device may push the abutting portion 111 to move the moving element 110 along the direction of the toner cartridge body and the pushing element 112 may be detached from the anti-attachment trench 126, as shown in
In the third step, the rotational driving force transmission part 999 on the image forming device may move along the direction of the toner cartridge body. Due to the interference between the rotational driving force transmission part 999 and the driving tooth 123, the support rod may be inwardly deviated along the radial direction of the rotating axis of the toner cartridge body, and the receiving element 120 may be engaged with the rotational driving force transmission part 999, as shown in
In the fourth step, the moving part 998 on the image forming device may move along the direction away from the toner cartridge body. Due to the existence of the first elastic element 150, the moving element 110 may follow the moving part 998 to move along the direction away from the toner cartridge body, until the pushing element 112 enters the anti-detachment trench 126, as shown in
In the fifth step, the image forming device may drag the transmission element 130 or the toner cartridge body to move along the direction (the same direction as the direction of the toner cartridge body in the third step) away from the rotational driving force transmission part 999. Since the support rod 124 may not be inwardly deviated along the radial direction of the rotating axis of the toner cartridge body and the receiving element 120 may not be disengaged from the rotational driving force transmission part 999, a gap may be between the receiving element 120 and the transmission element 130 to allow the developer stored in the toner cartridge body to flow out, as shown in
When the toner cartridge is uninstalled from the image forming device, in the state shown in
The structure of the force receiving part in one embodiment may be substantially same as the structure of the force receiving part in the first embodiment. The difference is that the force receiving part in one embodiment may further include a second elastic element 160, and in order to accommodate the second elastic element 160, the shape of the receiving element 120 may be modified.
As shown in
Compared with the force receiving part involved in the first embodiment, for the force receiving part in one embodiment, the second elastic element 160 may inwardly restrict the receiving element 120 along the radial direction due to the elastic force, such that the interference between the receiving tooth 123 and the image forming device during the installation and uninstallation process may be reduced, and the installation and uninstallation process of the toner cartridge may be prevented from being not smooth due to the friction and collision between the receiving tooth 123 and the image forming device.
Optionally, in order to prevent the aged and fractured second elastic element 160 from falling into the image forming device when the second elastic element 160 is a rubber product, which may damage the electronic image forming quality or the image forming device, the second elastic element may be connected to the receiving tooth 123 or the support rod 124. Bonding, thermoforming, interference fit, and the like may be selected, which may not be described in detail herein.
The structure of the force receiving part in one embodiment may be substantially same as the structure of the force receiving part in the first embodiment. The difference is that the structures of the moving elements 110a and the 110b in one embodiment may be different from the structure of the moving element 110 in the first embodiment.
The process of installing the toner cartridge into the image forming device is described in detail hereinafter. The moving part 997 on the image forming device may be located outside the rotational driving force transmission part 999.
In the first step, as shown in
In the second step, after the toner cartridge is installed in the image forming device, since the radial distance between the abutting portion 111a (111b) and the rotating axis of the toner cartridge body is greater than the radial distance between the receiving tooth 123 and the rotating axis of the toner cartridge body, the moving part 997 of the image forming device may push the abutting portion 111a (111b) to move the moving element 110a (110b) along the direction of the toner cartridge body and the pushing element 112a (112b) may be detached from the anti-attachment trench 126, as shown in
In the third step, the rotational driving force transmission part 999 on the image forming device may move along the direction of the toner cartridge body. Due to the interference between the rotational driving force transmission part 999 and the driving tooth 123, the support rod may be inwardly deviated along the radial direction of the rotating axis of the toner cartridge body, and the receiving element 120 may be engaged with the rotational driving force transmission part 999, as shown in
In the fourth step, the moving part 997 on the image forming device may move along the direction away from the toner cartridge body. Due to the existence of the first elastic element 150, the moving element 110a (110b) may follow the moving part 997 to move along the direction away from the toner cartridge body. However, unlike the first embodiment, the moving part 997 may limit the distance that the moving element 110a (110b) can move away from the toner cartridge, so that the abutting portion 112a (112b) may not completely enter the anti-detachment trench 126, as shown in
In the fifth step, the image forming device may drag the transmission element 130 or the toner cartridge body to move along the direction (the same direction as the direction of the toner cartridge body in the third step) away from the rotational driving force transmission part 999. The inward radial deviation of the support rod 124 along the radial direction of the rotating axis of the toner cartridge body is limited and the force required for the disengagement between the receiving element 120 and the rotational driving force transmission part 999 may be greatly greater than the friction between the receiving element 120 and the transmission element 130. Therefore, a gap may be formed between the receiving element 120 and the transmission element 130 to allow the developer stored in the toner cartridge body to flow out, as shown in
The uninstallation process of the force receiving part from the image forming device may be substantially same as the uninstallation process in the first embodiment, which may not be described in detail herein. The advantage of such design in one embodiment may be that, due to the problems such as precision and the like, the rotational driving force transmission part in certain machine models may still move a short distance along the direction of the toner cartridge during the process of uninstalling the toner cartridge from the image forming device. In such way, uninstalling the toner cartridge using the design in one embodiment may be easier than uninstalling the toner cartridge using the design in the first embodiment.
The moving element 110a is shown in
A moving part, including the first moving element 110c1 and the second moving element 110c2 which are independent of each other, may be mainly provided in one embodiment, and other parts may be the same as the force receiving part in the third embodiment.
The first moving element 110c1 and the second moving element 110c2 involved in one embodiment are shown in
However, when the internal parts of the image forming device are broken or deformed due to long work period, or when the internal parts of the image forming device interfere with the moving elements due to the precision problem during the production process of the image forming device, if the moving elements is an integrated structure, it may cause the movement of the moving elements to be restricted, so that the moving elements may not function normally and the toner cartridge may not be installed normally, which may affect the electronic image formation. However, in one embodiment, if the movement of the second moving element 110c2 is restricted, the first moving element 110c1 may still normally complete the function of the moving element to enable the toner cartridge to work normally, as shown in
For example, in the fourth step of the third embodiment, when the toner cartridge is installed on the image forming device, during the process of the moving part 997 on the image forming device moving away from the direction of the toner cartridge body, if the movement of the second moving element 110c2 is restricted, the first moving element 110c1 may still move normally away from the direction of the toner cartridge body and restrict the moveable portion 120. Therefore, the moving element 120 may not be disengaged from the rotational driving force transmission part 999 on the image forming device, as shown in
It should be noted that, in one embodiment, when the first moving element 110c1 is pushed toward the direction of the toner cartridge body to the maximum distance and the first moving element 110c1 is fixed, the distance that the second moving element 110c2 may move relative to the first moving element 110c1 away from the direction of the toner cartridge may be greater than or equal to the displacement of the second moving element 110c2 being pushed by the moving part 997 on the image forming device, which may ensure that in the states of
A force receiving part used for the toner cartridge is provided in one embodiment, which may enable the toner cartridge to receive the rotational driving force provided by the image forming device.
In the existing technology, the fixing protrusion 312 of the connecting portion 310 may be abutted against the transmission rod 326 of the driving head 320, thereby transmitting the rotational driving force from the driving head 320 to the connecting portion 310. In the present disclosure, the fixing protrusion 312 of the connecting portion 310 may be connected to the stopper 330 and the transmission rod 326 on the driving head 320 may be abutted against the transmission hole 333 on the stopper 330, thereby transmitting the rotational driving force from the driving head 320 to the stopper 300, and then from the stopper 300 to the connecting portion 310.
When the force receiving part, after being assembled, is installed on the toner cartridge body, as shown in
When the toner cartridge is installed in the image forming device and the toner is ready to flow out, the needle device in the rotational driving force transmission part of the image forming device may be abutted against the sixteenth abutting surface 3541 on the rod cap 354 of the rod 350 and may push the rod 350 to move along the direction away from the image forming device during the installation process. At this point, the fifteenth abutting surface 3521 on the pushing block 352 of the rod 350 may be separated from the seventh abutting surface 3265 on the transmission rod 326 of the driving head 320, such that the fourth abutting surface 3262 on the elastic transmission rod 326 may be separated from the protruding eave 313 of the connecting portion 310. Since the second elastic element 362 is in a compressed state, the second elastic element 362 may drive the driving head 320 and the moving element 340 to move along the direction away from the toner cartridge body, thereby separating the first abutting surface 311 on the connecting portion 310 from the eighth abutting surface 328 on the driving head 320 and generating a toner outlet for flowing out the toner between the first abutting surface 311 on the connecting portion 310 and the eighth abutting surface 328 on the driving head 320; the developer in the toner cartridge body may be transported to the vicinity of the toner outlet through the through hole 334 on the stopper 330, thereby transporting the developer to the image forming device; and at this point, the force receiving part is at a second position. The pushing device of the rotational driving force transmission part of the image forming device may be abutted against the twelfth abutting surface 341 on the moving element 340 and enable the moving element 340 to move along the direction toward the toner cartridge body. Then, the moving element 340 may return to the second position of the force receiving part. The driving tooth 321 of the driving head may obtain the rotational driving force from the rotational driving force transmission part, then the force is transmitted to the stopper 330 through the fixing rod 322 and the transmission rod 326 of the driving head 120 and then to the connecting portion 310, and finally drive the toner cartridge body to move jointly.
When the image forming device stops the image formation and the toner cartridge is read to be uninstalled, the pushing device of the rotational driving force transmission part of the image forming device may be abutted against the twelfth abutting surface 341 on the moving element 340 and enable the moving element 340 to move along the direction toward the toner cartridge body. The free end 3431 of the pushing rod 343 of the moving element 340 may be abutted against the sixth abutting surface 3264 on the transmission rod 326 of the driving head 320, and the driving head 320 and the moving element 340 may move along the direction toward the toner cartridge. When the eighth abutting surface 328 on the driving head 320 is abutted against the first abutting surface 311 on the connecting portion 310, the moving element 340 may continue to move along the direction toward the toner cartridge. As the moving element 340 continues to move, the fourth abutting surface 3262 on the transmission rod 326 of the driving head 320 may be abutted against the protruding eave 313 of the connecting portion 310. When the moving element 340 continues to move, the entire toner cartridge may move along the direction away from the rotational driving force transmission part, and the rod 350, relative to the toner cartridge, may move along the direction toward the rotational driving force transmission part, thereby returning the force receiving part to the first position.
The moving range of the driving head 320 may be restricted by the third abutting surface on the limiting protrusion 325 of the driving head 320 and the ninth abutting surface on the blocking portion 332 of the stopper 330. The moving range of the moving element 340 may be restricted by the fourteenth abutting surface 346 on the moving element 340 and the tenth abutting surface 336 on the stopper 330.
Optionally, the second elastic element 362 and the third elastic element 363 may be two ends of a spring mounted on the stopper 330; only the first elastic element 361 or the third elastic element 363 may be disposed to save costs, and both the first elastic element and the third elastic element may be disposed to ensure the part stability; and a sealing part may be disposed between the first abutting surface 311 on the connecting portion 310 and the eighth abutting surface on the driving head 320.
The force receiving part in one embodiment is substantially same as the force receiving part in the fifth embodiment, and the only difference is that an abutting block 347 and a support rod 348 may be disposed on the moving element 340 in one embodiment.
As shown in
As shown in
The working principle of the force receiving part in one embodiment is the same as the working principle of the force receiving part in the sixth embodiment, and the only difference is that the shape of the moving part 340 in one embodiment may be slightly different from the shape of the moving part in the sixth embodiment.
As shown in
Due to the gravity and errors in long-term abrasion and transmission, the rotating axis of the rotational driving force transmission part may not be coaxial with the rotating axis of the force receiving part and small error may be between the two rotating axes. Therefore, compared with the force receiving part in the sixth embodiment, the force receiving part in one embodiment may not be jammed due to the interference when the force receiving part rotates into the image forming device. However, compared with the force receiving part in the sixth embodiment, the design in one embodiment may have higher cost of production and modification.
In order to further facilitate the production and solve the assembly difficulty during the actual production process and long required labor hours for reassignment, the shapes and structures of the parts may be further improved in one embodiment, based on other above-mentioned embodiments. However, the principle of the entire force receiving part is the same as the principle of the force receiving part in the fifth embodiment.
As shown in
1) Compared with the moving element 340 in the fifth embodiment, the moving element may be divided into a first moving element 440a and a second moving element 440b in one embodiment, as shown in
2) Compared with the fifth embodiment where the twelfth abutting surface 341 is abutted against the image forming device, the second moving element 440b may include the support block 441 in one embodiment, the guide surface 441a and the contact end 441b may sequentially extend from the support block 441 along the direction away from the toner cartridge body, as shown in
3) Compared with the fifth embodiment where the limiting protrusion 325 is abutted against the blocking portion 332, the limiting protrusion may be deleted in the force receiving part in one embodiment, and the transmission rod 426 may be directly used to pass through the transmission hole 333 and may be abutted against the hole wall of the transmission hole 333, as shown in
4) Compared with the fifth embodiment where the fixing rod 322 supports the driving tooth 321, four fixing rods 422 may be disposed in one embodiment, where the driving teeth 421a may be disposed on two symmetrical fixing rods 422 relative to the rotating axis of the force receiving part, and the driving teeth 421a may not be disposed on two symmetrical fixing rods 422 relative to the rotating axis of the force receiving part, as shown in
Finally, it should be noted that the above-mentioned embodiments may be merely used to describe the technical solution of the present disclosure, rather than limiting the present disclosure. Although the present disclosure has been described in detail with reference to the above-mentioned embodiments, those skilled in the art should understand that the technical solutions described in the above-mentioned embodiments may still be modified, or a part or all of the technical features may be equivalently replaced. Such modifications or replacements do not make the essence of the corresponding technical solutions outside the scope of the technical solutions of the embodiments of the present disclosure.
The force receiving part and the toner cartridge provide in the embodiments of the present application may avoid the situation where the driving tooth structure of the toner cartridge and the internal engagement of the image forming device are locked in the existing technology, also reduce the possibility of errors in the operation of the machine and improve the tightness of the machine, and further effectively prevent the developer in the toner cartridge from leaking which may pollute the environment and affect the image forming quality.
