The invention relates to the technical field of manual paper cutters, in particular to a hand-pushed paper cutting apparatus.
A paper cutter, also known as a guillotine, is a tool specifically designed for cutting paper. Its main function is to precisely cut paper to the desired size and shape using a sharp blade. Manual paper cutters require the user to manually push the blade to make cuts, and are suitable for small sheets of paper and limited cutting needs.
The existing U.S. Pat. No. 11,717,977 discloses a “Paper Cutter”. This manual paper cutter features a cylindrical structure, making it large and inconvenient to carry. Additionally, the paper cutter lacks a movement guiding mechanism, which can lead to misalignment during cutting, adversely affecting the cutting quality and results.
Therefore, it is necessary to propose a novel paper cutter which is smaller in size, with a simple and compact structure, and offers improved cutting performance.
The invention provides a hand-pushed paper cutting apparatus to address the issues raised in the background art.
To achieve the above object, the invention provides a hand-pushed paper cutting apparatus, comprising a main body and a blade assembly installed on the main body; the main body has at least one end face oriented toward paper, the end face is configured as a cutting face, the cutting face is provided with a receiving groove for installing the blade assembly; the blade assembly comprises a blade holder and a blade, and a gap exists between the blade holder and an inner wall of the receiving groove is designated as a cutting area; the cutting area features a feeding end and a cutting end, and a paper movement direction is formed between the feeding end and the cutting end; the cutting face is provided with paper pressing sections for tensioning the paper, and the paper pressing sections are located on two sides of the paper movement direction; the blade holder has at least one supporting face facing the cutting area, and the supporting face, in conjunction with the paper pressing sections, tensions the paper; the cutting area is further provided with a guiding section extending toward the supporting face to direct the paper toward the blade; and the cutting face is also provided with a walking mechanism designed to maintain linear movement of the main body and located on two sides of the paper movement direction.

As shown in
Refer to
By providing the receiving groove 102 in the cutting face 101, the blade assembly 200 can be accommodated. In this way, the installed blade 202 will be positioned within the receiving groove and blocked, preventing contact with the human body and potential cuts, while also protecting the blade 202 from damage.
Refer to
By setting up the cutting area, the paper can pass through the space between the blade holder 201 and the receiving groove 102, allowing the blade 202 to cut the paper as it moves through. During the cutting process, the paper pressing sections 103 and the supporting face work together to tension the paper passing through the cutting area 1021, ensuring smoother cutting and better cutting results.
The guiding section 104 plays a guiding role during the paper cutting process, allowing the paper to move toward the blade 202. Meanwhile, the supporting face 2012 works in conjunction with the guiding section 104 to impose vertical constraints on the paper, reducing the vertical movement of the paper and further enhancing the cutting effect. The main body 100 can move along a plane with paper placed thereon via the walking mechanism 300.
According to the above description, in a preferred embodiment of the receiving groove 102 and the cutting area, as shown in
In this embodiment, the paper can enter the cutting area 1021 through the feeding end 1022 and then move to the cutting end 1023, forming the paper movement direction. After reaching the cutting end 1023, the paper will come into contact with the blade 202, and the blade 202 can then cut the paper, as shown in
According to the above description, in a preferred embodiment of the guiding section 104, the supporting face 2012, and the paper pressing sections 103, as shown in
In this embodiment, the paper pressing sections 103 extend downward and are lower than the supporting face 2012, allowing the supporting face 2012 to support a bottom surface of the paper as the paper passes through the cutting area. Meanwhile, the paper pressing sections 103 on two sides can press down on an upper surface of the paper. This causes the paper to arch upward and become tensioned as it passes through, as shown in
In this embodiment, the guiding section 104 is arranged parallel to the supporting face 2012 in the vertical direction. During paper cutting, the supporting face 2012 and the guiding section 104 work together to impose vertical constraints on the paper, reducing the vertical movement of the paper and further enhancing the cutting effect.
Further, in this embodiment, two ends of the guiding section 104, facing the feeding end 1022 and the cutting end 1023, are inclined surfaces. The inclusion of the inclined surfaces on the guiding section 104 makes it easier to guide the paper into the space between the guiding section 104 and the supporting face 2012, thereby improving the guiding effect. Of course, the shape of the guiding section 104 is not limited to the aforementioned embodiment; in other embodiments (not shown in the figures), the guiding section 104 may also be in an arc shape or have a long strip shape with rounded corners, and it may also be designed as a rotating guide wheel, among other options.
In one embodiment of the invention, as shown in
In this embodiment, the pointed tip 2014 transitions smoothly into the supporting face 2012, allowing the pointed tip 2014 to penetrate the bottom of the paper during cutting and guide the paper to slide onto the supporting face 2012.
As shown in
In other embodiments of the walking mechanism 300 (not shown in the figures), the walking mechanism 300 may also be configured as tracks, with at least two tracks positioned on either side of the paper movement direction. By using tracks for movement, the contact area between the walking mechanism 300 and the plane is increased, enhancing the stability of the main body 100 during linear movement and making it less likely to tilt.
In one embodiment of the invention, the main body 100 is provided with a grip 105, and the grip 105 is located on an end face parallel to the cutting face 101. When using the paper cutting apparatus, the grip 105 can be grasped by hand to push the main body 100 across the plane.
Further, the grip 105 is located between two parts of the walking mechanism 300 on two sides. By positioning the grip 105 between two parts of the walking mechanism 300, the force applied when pushing the main body 100 for movement can be evenly distributed across the walking mechanism 300 on two sides, thereby avoiding uneven stress that could cause deviation of the main body 100.
In one embodiment of the invention, as shown in
In this embodiment, the main body 100 is divided into two vertically interlocked parts, with the connecting end 2013 of the blade holder 201 inserted into the lower part of the main body 100 and further reinforced with bolts. When it is necessary to disassemble the blade assembly 200, one only needs to separate the upper and lower parts of the main body 100 and then unscrew the bolts to remove the blade assembly 200 from the main body 100, facilitating the replacement of the blade assembly 200. If the blade 202 needs to be replaced, it can simply be pulled out from the installation groove 2011 and replaced.
Of course, the detachable connection method between the blade assembly 200 and the main body 100 is not limited to the aforementioned approach; in other embodiments (not shown in the figures), it may also be snap-fit connection, screw connection, and other detachable connection methods.
Additionally, in other embodiments (not shown in the figures), the blade assembly 200 and the main body 100 may be connected using a completely fixed method, such as integrally molded connection, fusion bonding, welding, and other fixed connection methods.
Further, in other embodiments (not shown in the figures), the blade assembly 200 and the main body 100 may be connected using a rotational connection method. For example, a pivot shaft is arranged between the connecting end 2013 and the main body 100, allowing the blade assembly 200 to rotate and engage within the receiving groove 102 during use. When it is necessary to replace the blade 202, the blade assembly 200 can be flipped out of the receiving groove 102 for replacement of the blade 202.
In summary, from the above description, it can be seen that the invention achieves the following technical effects:
In the description of the invention, it should be understood that the orientation or positional relationship indicated by directional words such as “front, back, upper, lower, left, right”, “lateral, upright, vertical, horizontal” and “top, bottom” are usually based on the orientation or positional relationship shown in the attached drawings, just for the convenience of describing the invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so they cannot be understood as limiting the scope of protection of the invention. The directional words “inside, outside” refer to the inside and outside relative to the outline of each component itself.
For the convenience of description, spatially relative terms such as “on”, “over”, “on the upper surface of” and “above” can be used here to describe the spatial positional relationship between a device or feature as shown in the figure and other devices or features. It should be understood that spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation of the device depicted in the drawings. For example, if the devices in the drawings are inverted, devices described as “over” or “on” other devices or structures will be positioned as “under” or “below” other devices or structures. Thus, the exemplary term “over” can include both orientations of “over” and “under”. The device can also be positioned in other different ways (rotated by 90 degrees or in other orientations), and the spatial relative description used here is explained accordingly.
In addition, it should be noted that the words “first” and “second” are used to define parts only for the convenience of distinguishing the corresponding parts. Unless otherwise stated, the above words have no special meaning, so they cannot be understood as limiting the protection scope of the invention.
The above embodiments are only preferred ones of the invention, and are not used to limit the invention. For those skilled in the art, the invention may have various modifications and changes. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the invention should be included in the protection scope of the invention.
