[0002] At present, in the production process of paper printing, the paper must be arranged in order and the thickness must be certain when cutting the paper, so that the paper can be reliably positioned by the paper cutting machine, thereby the paper cutting work is carried out. But in the actual paper cutting, due to the thickness of the paper and the displacement of the stacked paper in the conveying process, the thickness of the paper at different positions in a stack is not the same, which causes errors in the paper cutting process, thereby causing the problem that the cutting sizes of different papers in a batch are not the same. In addition, in the traditional technology, when the staff places the stacked paper with a certain thickness under the cutter of the paper cutting machine, manual positioning and simple pressing of the paper are needed, which cannot guarantee the accuracy of cutting and is low in production efficiency.

[0008] In some embodiments, the spacing between adjacent through holes is equal.

[0009] In some embodiments, the ring-shaped frame is a rectangular frame.

[0010] In some embodiments, the elastic member comprises a straight spring.

[0011] In some embodiments, one end of the elastic member is connected to an end surface of the slide rod, and the other end of the elastic member is connected to the support component.

[0012] In some embodiments, in the reset state, the ends of the slide rods away from the support component are flush, so that the plurality of paper pressing members are flush.

Specifically, this application utilizes a combination of elastic elements, sliding rods, and paper-pressing elements. The pressing process allows for self-adjustment of the pressing position based on the paper thickness. When the paper is placed below the paper cutter, the pressing support component descends, causing the adjusting and pressing components to descend to the paper. At thicker sections of the paper, the paper-pressing element contacts the paper first, squeezing the sliding rod. After a certain degree of compression, the elastic element restrains the sliding rod, causing it to remain in position after descending a certain distance. Similarly, at other thicknesses, the paper-pressing elements on the sliding rods sequentially contact the paper. The paper lifts each paper-pressing element and the sliding rod, causing the elastic element above the sliding rod to press against it. This ensures that each section of the paper is pressed by the paper-pressing elements, achieving fixation. This application can press and fix the paper at multiple positions, adapting to different thicknesses, improving fixing accuracy and cutting precision, and reducing waste.

[0032] This application provides a paper fixing device 10 to solve at least one of the following technical problems in paper cutting: (1) Due to the thickness of the paper and the displacement of the stacked paper during handling, the thickness of a stack of paper varies at different positions, causing errors in the paper cutting process, resulting in different cutting sizes of different papers in a batch. (2) When workers carry stacked paper of a certain thickness under the cutter of the paper cutter, they need to manually position and simply press the paper to fix it. This operation cannot guarantee the accuracy of cutting and has low production efficiency. The paper fixing device 10 will be described below with reference to the accompanying drawings.

[0033] The paper fixing device 10 provided in this application embodiment is exemplary; please refer to [link to example]. Figure 1 As shown, Figure 1 This is a schematic diagram of the paper fixing device 10 provided in an embodiment of this application. The paper fixing device 10 of this application can be used to press and fix a stack of papers with different thicknesses at different positions, which is convenient for cutting purposes.

[0034] To more clearly illustrate the structure of the paper fixing device 10, the paper fixing device 10 will be described below in conjunction with the accompanying drawings.

[0035] For example, please refer to Figure 1 As shown, a paper fixing device 10 includes a support member 100, an adjusting member 200, and a pressing member 300. The support member 100 is movably mounted on a paper cutter. The support member 100 can move up and down relative to the paper cutter to press the paper.

[0036] The adjusting component 200 includes a slide rod 201 and an elastic element 202. The slide rod 201 is connected to the support component 100 via the elastic element 202. The slide rod 201 at least partially protrudes from the support component 100. There are multiple adjusting components 200. The multiple adjusting components 200 are sequentially distributed along the same direction.

[0037] The pressing component 300 includes multiple paper pressing elements 301. Each slide bar 201 is connected to a paper pressing element 301, and all paper pressing elements 301 are located on the same side of the support component 100. The multiple paper pressing elements 301 cooperate with each other to press the paper.

[0038] The aforementioned paper fixing device 10 is simple to manufacture, easy to use, and practical and reliable. This invention improves the positioning accuracy and pressing range of the paper, ensuring that all positions of a stack of paper of varying thicknesses are effectively pressed and fixed, thereby improving cutting accuracy, reducing waste, and increasing production efficiency.

[0039] In some of these embodiments, please refer to Figure 1As shown, the support component 100 includes an annular frame. Multiple through holes are provided on one side wall of the annular frame. Each through hole corresponds to a slide rod 201, which passes through the through hole with one end inside the annular frame and the other end extending to the outside of the annular frame. An elastic element 202 is disposed inside the annular frame. It should be noted that "inside the annular frame" refers to the space enclosed by the annular frame.

[0040] In some embodiments, multiple through holes extend along the length of the sidewall of the annular frame.

[0041] In some of these embodiments, please refer to Figure 1 As shown, the spacing between adjacent through holes is equal.

[0042] In some embodiments, the annular frame is a rectangular frame. The annular frame has a certain length, width, and thickness to facilitate the fabrication of through holes in the sidewalls. The through holes are located on one of the longer sidewalls of the annular frame.

[0043] In some embodiments, the inner diameter of the through hole is slightly larger than the outer diameter of the slide bar 201 to allow the slide bar 201 to move within the through hole. It is easy to understand that in other examples, the through hole can also be of other shapes, as long as the shape of the through hole matches the shape of the slide bar 201. For example, when the radial cross-section of the slide bar 201 is circular, the through hole is circular; when the radial cross-section of the slide bar 201 is rectangular, the through hole is rectangular, and so on. This is not an exhaustive list.

[0044] In some embodiments, the elastic element 202 includes a linear spring. The linear spring facilitates the application of force along the length of the slide bar 201 and provides an elastic restoring force.

[0045] In some of these embodiments, please refer to Figure 1 As shown, one end of the elastic element 202 is connected to the end face of the slide rod 201, and the other end of the elastic element 202 is connected to the support component 100.

[0046] In some embodiments, when the elastic element 202 is in the reset state, the ends of each slide bar 201 away from the support member 100 are flush, so that the multiple paper pressing parts 301 are flush. After the paper fixing device 10 is installed on the paper cutter, the slide bar 201 is arranged vertically, and each paper pressing part 301 is located below the slide bar 201, so that the elastic element 202, slide bar 201, and paper pressing parts 301 are in a state of self-weight hanging. All elastic elements 202 are of the same type, and all slide bars 201 are of the same length. This ensures that when the paper fixing device 10 is in the reset state, the bottom surfaces of all paper pressing parts 301 are at a uniform horizontal height.

[0047] In some of these embodiments, please refer to Figure 1As shown, the clamping component 300 also includes a connector 302. Adjacent paper clamping components 301 are movably connected via the connector 302. It should be noted that, see [link to previous section]... Figure 1 and Figure 2 The angle shown Figure 2 This is a schematic diagram from another angle of the paper fixing device according to an embodiment of the present invention. After the connector 302 is connected to the two adjacent paper pressing parts 301, the bottom surface of the connector 302 is flush with the bottom surface of the paper pressing parts 301. That is, the bottom surface of the connector 302 should not protrude from the bottom surface of the paper pressing parts 301, so as to ensure that the surface of the paper pressing parts 301 in contact with the paper plays a pressing role. The bottom surface of the connector 302 can cooperate with the surface of the paper pressing parts 301 in contact with the paper.

[0048] In some of these embodiments, please refer to Figure 1 As shown, the paper pressing component 301 can be a track strip.

[0049] In some embodiments, between adjacent paper pressing elements 301, one end of a connecting member 302 is hinged to one of the paper pressing elements 301, and the other end of the connecting member 302 is hinged to another paper pressing element 301, so that multiple paper pressing elements 301 and multiple connecting members 302 form a chain structure. Please refer to the connected chain structure. Figure 1 As shown.

[0050] One embodiment of this application also provides a paper cutting device.

[0051] A paper cutting device includes a paper cutter and a paper fixing device 10 as described in any of the above embodiments. The paper fixing device 10 is connected to the paper cutter and is used to press and fix the paper.

[0052] In some embodiments, the paper cutter may be a paper cutter of the prior art.

[0053] For example, in some embodiments, the basic structure of a paper cutter typically includes the following basic components:

[0054] Machine body: Provides a robust support structure, ensuring stability and safety during machine operation. The machine body is typically made of metal to withstand the pressure and stress during the cutting process.

[0055] Workbench: The place where the paper to be cut is placed. The surface of the workbench is usually flat and smooth, and some models are also equipped with rulers and scale lines to help users align the paper more accurately.

[0056] Blade: This is the core component of the paper cutter, responsible for the actual cutting operation. The quality and sharpness of the blade directly affect the cutting effect and precision. The blade can be a straight blade or a rotary blade, depending on the different machine models.

[0057] The paper fixing device 10 in any of the above embodiments: fixes the paper during the cutting process, prevents the paper from moving, and ensures the accuracy and consistency of the cutting. The paper fixing device 10 in any embodiment of this application can be adapted to thicker stacks of paper. The paper fixing device 10 is mounted on a worktable and can move up and down under the drive of a drive component.

[0058] Control panel: Used to set cutting parameters and start the cutting process, allowing users to perform more detailed operation settings, such as cutting size and cutting quantity. The control panel is electrically connected to the drive components of the paper fixing device 10, the blade drive components, the safety device, and the positioning system.

[0059] Safety devices include, but are not limited to, protective covers and emergency stop buttons, used to protect the safety of operators and prevent accidental injury.

[0060] Positioning system: Helps users precisely adjust the paper's position to ensure that each cut achieves the expected size. Common positioning systems include side guides and back guides.

[0061] The control panel is electrically connected to the drive components of the paper holder 10, the drive components of the blade, the safety device, and the positioning system.

[0062] In summary, this application, through the combination of slide bar 201, elastic element 202, and paper pressing element 301, allows the pressing position to be automatically adjusted according to the paper thickness during the paper pressing process. When the paper is placed under the paper cutter, the pressing support component 100 descends to drive the adjusting component 200 and the pressing component 300 down to the paper. At the thicker part of the paper, the paper pressing element 301 contacts the paper first, and the paper squeezes the slide bar 201. After being squeezed to a certain extent, due to the restraint of the elastic element 202, the slide bar 201 remains stationary after descending a certain distance. With the paper holding position unchanged, similarly, the paper pressing parts 301 on the slide bar 201 at other thickness positions sequentially contact the paper. The paper pushes up each paper pressing part 301 and the slide bar 201. The elastic element 202 above the slide bar 201 is forced to press the slide bar 201 in the opposite direction, so that each fixed part of the paper is pressed by the paper pressing part 301, thus achieving fixation. This application can press and fix the paper at multiple positions and achieve adaptive fixation for positions with different thicknesses, improving the fixation accuracy, improving the cutting accuracy, and reducing the generation of waste.

[0063] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
