There exist a major disadvantage in association with the above-mentioned conventional heat press machine. In order to imprint predetermined graphics or characters on the work piece 80P, it must be horizontally supported on the lower supporting plate 30P, and must be fittedly sandwiched between the lower supporting plate 30P and the upper heating plate 20P. As a result, the work piece 80P must not have significant thickness or it cannot be fittedly sandwiched between the upper heating plate 20P and the lower supporting plate 30P. Hence, conventional heat press machines such as the one disclosed above are only capable of imprinting graphics or characters onto a limited categories of products. For example, conventional heat press machines may be used to imprint graphics on T-shirts, pants, or other clothing. For other products such as backpacks which do not have flat or panel-like structure, conventional heat press machines are not suitable. This is due to the fact that when such a product (e.g. a backpack) is put on the lower supporting plate 30P, the upper heating plate 20P is prevented from fittedly biasing against the lower supporting plate 30P, and the work piece 80P cannot be flatly or horizontally supported on the lower supporting plate 30P. When this happens, the imprinting process of the heat press machine will become infeasible, as shown in

The following detailed description of the preferred embodiment is the preferred mode of carrying out the invention. The description is not to be taken in any limiting sense. It is presented for the purpose of illustrating the general principles of the present invention.
Referring to
The main body 20 is supported on the worktable 11 of the adjustable supporting frame 10. The actuating handle assembly 30 movably extends from the main body 20 to allow a user to actuate an imprinting process of the heat pressing assembly 40.
The heat pressing assembly 40 comprises a first pressing member 41 and a second pressing member 42. The first pressing member 41 is connected to the actuating handle assembly 30 and defines a lower biasing surface 411.
The second pressing member 42 suspendedly extends from a lower portion of the main body 20 to define an upper biasing surface 421 and an operational space 422 underneath the second pressing member 42. The heat pressing assembly 40 is arranged to operate between an idle position and a heat press position, wherein in the idle position, the first pressing member 41 and the second pressing member 42 are pivotally moved away from each other, wherein in the heat press position, the imprinting surface 81 of the work piece 80 is arranged to rest on the upper biasing surface 421 while other parts of the work piece 80 are allowed to temporarily accommodate in the operational space 422, wherein the first pressing member 41 is pivotally moved to allow the lower biasing surface 411 to bias against the upper biasing surface 421 and the imprinting surface 81 of the work piece 80 for imprinting predetermined graphics or characters on the imprinting surface 81 through the use of a sublimation paper.
According to the preferred embodiment of the present invention, the adjustable supporting frame 10 comprises a lower supporting frame 12 and an upper supporting frame 13 adjustably mounting on the lower supporting frame 12, in such a manner that the upper supporting frame 13 is adapted to move along a longitudinal direction thereof for adjusting a height of the adjustable supporting frame 10. Note that the top worktable 11 is provided on the upper supporting frame 13 so that when it moves along a longitudinal direction thereof, the height of the main body 20 with respect to the ground can also be adjusted.
Furthermore, the adjustable supporting frame 10 further comprises an auxiliary supporting platform 14 mounting on the upper supporting frame 13 in a slidably movable manner at a position below the top worktable 10 in the operational space 422, wherein the user is able to selectively and horizontally extend the auxiliary supporting platform 14 for supporting the work piece 80. When it is not necessary, the user may slide the auxiliary supporting frame 14 towards the adjustable supporting frame 10 and hide it underneath the top worktable 11. The auxiliary supporting platform 14 is necessary when the work piece 80 is too bulky in size. The imprinting surface 81 of the work piece 80 may be supported by the second pressing member 42 while the remaining portions or parts of the work piece 80 may be supported by the auxiliary supporting platform 14, as shown in
The main body 20 is securely supported on the top worktable 11 of the adjustable supporting frame 10, and comprises a first supporting member 21 and a second supporting member 22 mounted on the top worktable 11 at a position spacedly apart from the first supporting member 21 to define a receiving cavity 23 between an inner side of the first supporting member 21 and an inner side of the second supporting member 22.
The universal heat press machine further comprises a heating device 50 supported by the main body 20 for providing heat to the first pressing member 41 of the heat pressing assembly 40. The heating device 50 comprises a plurality of control housings 51 mounted on outer sides of the first supporting member 21 and the second supporting member 22 respectively, wherein each of the control housings 51 may have a plurality of operational switches 52 and displays 55 for allowing a user to control an operation of the universal heat press machine.
Moreover, the heating device 50 further comprises a heat generation module 53 supported in at least one of the control housings 50 and electrically extends to the first pressing member 41 of the heat pressing assembly 40 for controllably increasing a temperature of the first pressing member 41.
The heat generation module 53 is arranged to increase the temperature of the first pressing member 41 so that when it is pivotally moved to bias against the work piece 80 and the second pressing member 42, predetermined graphics or characters may be imprinted on the work piece 80 through the use of a sublimation paper 70 having a predetermined pattern thereon.
As shown in
As shown in
In order to facilitate the pivotal movement of the extension member 33, the actuating handle assembly 30 further comprises a plurality of hydraulics pistons 34 mounting on inner sides of the first supporting member 21 and the second supporting member 22 respectively, wherein the hydraulics pistons 34 are connected to the extension member 33 for pivotally coupling the extension member 33 with the main body 20.
The first pressing member 41 of the heat pressing assembly 40 is configured as a heat plate for providing heat energy to imprint the predetermined graphics or characters onto the work piece 80. Accordingly, the heat generation module 53 may comprise a heating element 531 (schematically shown in
On the other hand, the second pressing member 42 is arranged to be detachably attached on the main body 20. In this preferred embodiment, the second pressing member 42 comprises a mounting track 423 movably extending from the main body 10, and a supporting plate 424 detachably and adjustably mounting on the mounting track 423. Thus, the second pressing member 42 may comprise a plurality of supporting plates 424 each having differing size for being selectively mounted on the mounting track 423. Depending on the size of the work piece 80, a user of the present invention is able to select the most suitable supporting plate 424 and mount it on the mounting track 423 for imprinting the graphics or characters on the work piece 80.
Specifically, as shown in
Referring to
The position of the mounting track 423 of the second pressing member 42 is adjustable with respect to the main body 20 so as to allow the universal heat press machine to accommodate the maximum types of work pieces 80. More specifically, the heat pressing assembly 40 further comprises a lifting device 43 providing on the main body 20 and coupled to the second pressing member 42 to selectively lift up and move down the mounting track 423 of the second pressing member 42.
The lifting device 43 comprises a lifting actuator 431 having a bottom lifting end portion 4311 connected to the mounting track 423 of the second pressing member 42. When the lifting actuator 431 is actuated, the lifting actuator 431 and the mounting track 423 is driven to move vertically with respect to the main body 20 so as to adjust a height of the second pressing member 42 with respect to the main body 20.
Specifically, the lifting actuator 431 further has a top actuating wheel portion 4312, and a rod portion 4313 extending between the top actuating wheel portion 4312 and the bottom lifting end portion 4311. As shown in
The securing member 432 has a bored hole 4321 while the rod portion 4313 has a threaded outer surface 4314. The rod portion 4313 is arranged to penetrate the bored hole 4321 of the securing member 432 in such a manner that the bored hole 4321 engages with the threaded outer surface 4314 of the rod portion 4313. As such, when the top actuating wheel portion 4312 is turned, the rod portion 4313 is also turned. This turning movement allows the rod portion 4313 to move in a longitudinal direction thereof as guided by the engagement between the bored hole 4321 and the threaded outer surface 4314 of the rod portion 4313. The longitudinal movement of the rod portion 4313 drives the bottom lifting end portion 4311 to move upwardly or downwardly with respect to the main body 20 so as to move the second pressing member 42 upwardly or downwardly with respect to the main body 20. As a result, the height of the second pressing member 42 can be adjusted by turning the lifting actuator 431 of the lifting device 43.
As shown in
The lifting device 43 further comprises a locking device 433 comprising a plurality of locking pins 4331 extending from two sides of the mounting track 423, a plurality of locking knobs 4332 provided at outer ends of the locking pins 4331 respectively, and containing a plurality of locking slots 4333 forming on the first supporting member 21 and the second supporting member 22 respectively, wherein each of the locking pins 4332 extends from the lifting member 432 to an exterior of the main body 20 through the corresponding locking slot 4333.
Thus, when the second pressing member 42 moves upwardly or downwardly with respect to the main body 20, the locking pins 4331 slides along the corresponding locking slots 4333. The locking knobs 4332 may be turned to bias against the main body 20 for locking up a movement of the second pressing member 42. However, when the locking knobs 4332 are turned to move away from the main body 20, the lifting actuator 431 and the second pressing member 42 are free to move upwardly or downwardly through the actuation of the top actuating wheel portion 4312.
The operation of the present invention is as follows: a user may choose the most suitable supporting plate 424 from a set of supporting plates 424 having different sizes. The user may mount the selected supporting plate 424 to the mounting track 423 by using the fastener 425. When the supporting plate 424 is mounted on the mounting track 423, the user may insert the second pressing member 42 into a cavity of the work piece 80, such as a storage compartment of a backpack, such that the imprinting surface 81 of the work piece 80 is well supported by the second pressing member 42 and is held facing upward towards the first pressing member 41. It is important to mention that with this design of the universal heat press machine of the present invention, the remaining portion of the work piece 80 may be suspendedly supported in the operational space 422. In order to better support the work piece 80, the auxiliary supporting platform 14 may slidably extend from underneath the top worktable 11 of the adjustable supporting frame 10 to provide better support to the work piece 80, as shown in
The user may then adjust the height of the second pressing member 42 as mentioned above. When the second pressing member 42 is properly positioned, a sublimation paper 70 is disposed on top of the imprinting surface 81 of the work piece 80. The user may then operate the heating device 50 and allow the first pressing member 41 to be heated up to a predetermined temperature. After that, the user may grab the actuating handle assembly 30 and pivotally move it to bias against the second pressing member 42. The imprinting surface 81 of the work piece 80 and the sublimation paper 70 are sandwiched between the first pressing member 41 and the second pressing member 42. After a predetermined period of time (usually few seconds), the user may then move the first pressing member 41 back to its original position. A predetermined graphics or characters are now imprinted on the imprinting surface 81 of the work piece 80.
The advantage of the universal heat press machine of the present invention is that by allowing the user to select the optimal supporting plate 424 and providing the operational space 422 underneath the second pressing member 42, the user is able to imprint predetermined graphics or characters onto a wide variety of work pieces 80. As long as the imprinting surface 81 of the work piece 80 may be fitted onto the second pressing member 42, the shape or contour of the remaining portions of the work piece 80 is immaterial, because it can easily be accommodated in the operational space 422 and may also be supported by the auxiliary supporting platform 14.
The present invention, while illustrated and described in terms of a preferred embodiment and several alternatives, is not limited to the particular description contained in this specification. Additional alternative or equivalent components could also be used to practice the present invention.
