Description

Technical Field

[0001] This utility model relates to the field of paper cutter technology, and in particular to a paper pressing device for a paper cutter. Background Technology

[0002] In the paper cutter's operation process, edge alignment and pre-compression of the stacked paper are crucial preliminary steps to ensure cutting accuracy. Traditional operation relies on two separate steps: First, the operator needs to hold an L-shaped wooden or plastic pusher and repeatedly push the side edge of the paper stack to make it fit tightly against the back gauge and side gauge of the paper cutter; then, the paper pressing device built into the paper cutter is activated to press down and fix the entire stack of paper.

[0003] However, this paper pressing method has certain drawbacks: First, the separation of manual paper pushing and mechanical paper pressing actions leads to low efficiency, especially exacerbating operator fatigue in high-frequency cutting scenarios; Second, after the operator pushes the paper to the correct position, they need to remove their hand from the work area before starting the paper pressing mechanism. During this process, the already aligned paper stack may shift again due to minor disturbances, forcing repeated adjustments and directly affecting the consistency of cutting.

[0004] Therefore, this application provides a paper pressing device for a paper cutter to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a paper pressing device for a paper cutter, so as to solve the problems of low efficiency caused by the separate execution of manual paper pushing and mechanical paper pressing in the existing operation, and the cutting accuracy defects caused by the secondary displacement of the paper stack after the operator removes the paper pushing block.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A paper-pressing device for a paper cutter includes a paper-pushing block with an L-shaped cross-section. A handle is fixed to the middle of the inner side of the paper-pushing block. A vertical column is fixed to the top of the paper-pushing block. A base plate extending horizontally outward from the outer side of the paper-pushing block is fixed to the top of the column. A pressure plate that can slide vertically up and down is elastically installed on the lower end face of the base plate. A linkage plate is hinged to the lower end face of the base plate. The lower end of the linkage plate is horizontally slidably installed on the upper end face of the pressure plate. A transmission rod that passes horizontally through the middle of the column is movably connected to the middle of the linkage plate. The end of the transmission rod extends above the handle and is fixed with a hook.

[0008] Optionally, a vertical limiting post is fixed at the middle of the upper end face of the pressure plate, the limiting post vertically penetrates the substrate, and a reset spring is sleeved on the limiting post.

[0009] Optionally, the upper end of the reset spring is fixed to the lower end face of the substrate, and the lower end of the reset spring is fixed to the upper end face of the pressure plate.

[0010] Optionally, a rubber pad is fixed to the lower end face of the pressure plate.

[0011] Optionally, a limiting groove is provided in the middle of the upper end surface of the pressure plate, and the lower end of the linkage plate is horizontally slidably placed in the limiting groove.

[0012] Optionally, the bottom sides of the limiting slide groove are symmetrically provided with concave slide tracks, and the lower ends of the linkage plate are symmetrically fixed with limiting protrusions, which slide in cooperation with the slide tracks on both sides of the bottom of the limiting slide groove.

[0013] Optionally, two mounting ears are symmetrically fixed in the middle of the linkage plate, and the end of the transmission rod is rotatably mounted between the two mounting ears.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above solution, this utility model achieves synchronous and integrated operation of paper alignment and local pressing through the mechanical linkage design of the paper pusher, pressure plate, and transmission rod. When the operator holds the handle of the paper pusher with one hand and pushes the paper stack to the stop gauge, he only needs to pull the hook horizontally to drive the linkage plate to slide through the transmission rod, forcing the pressure plate to press down on the surface of the paper stack in the vertical direction. The whole process does not require switching tools or removing hands, completely eliminating the problem of secondary paper stack displacement caused by manual removal in traditional step-by-step operations.

[0016] In the above solution, this utility model adopts a special mechanical transmission structure. By sliding the lower end of the linkage plate with the pressure plate, the horizontal tension is accurately converted into vertical downward pressure, so that the operator's hands can stay away from the danger zone of the paper cutter head throughout the process, and it can automatically spring back to reset after pressing, with a high safety factor.

[0017] In summary, this device not only allows for pressing down the paper stack during alignment, avoiding the problems of accuracy deviations and repeated adjustments caused by step-by-step operations, but also keeps the operator's hands away from the dangerous area of ​​the paper cutter head during operation, further improving the safety factor during operation. Overall, it has a good performance. Attached Figure Description

[0031] like Figure 1-4 As shown, an embodiment of this utility model provides a paper pressing device for a paper cutter, including a paper pusher block 1 with an L-shaped cross-section. A handle 2 is fixed to the middle of the inner side of the paper pusher block 1. A vertical column 3 is fixed to the top of the paper pusher block 1. A base plate 4 that extends horizontally outward from the outer side of the paper pusher block 1 is fixed to the top of the column 3. A pressure plate 5 that can slide vertically up and down is elastically installed on the lower end surface of the base plate 4. The side of the pressure plate 5 slides vertically against the outer side wall of the column 3 to ensure the up and down sliding of the pressure plate 5.

[0032] Specifically, a vertical limiting post 6 is fixed to the middle of the upper end face of the pressure plate 5. The limiting post 6 vertically penetrates the substrate 4, and a return spring 7 is sleeved on the limiting post 6. The upper end of the return spring 7 is fixed to the lower end face of the substrate 4, and the lower end of the return spring 7 is fixed to the upper end face of the pressure plate 5, forming an elastic installation of the pressure plate 5, which facilitates the automatic reset of the pressure plate 5 after pressing down the paper stack. In addition, a rubber pad 501 is fixed to the lower end face of the pressure plate 5 to ensure the pressing effect on the paper stack.

[0033] Meanwhile, a linkage plate 8 is hinged to the lower end face of the substrate 4. The lower end of the linkage plate 8 is horizontally slidably mounted on the upper end face of the pressure plate 5. A transmission rod 9 that horizontally penetrates the middle of the column 3 is movably connected to the middle of the linkage plate 8. The end of the transmission rod 9 extends above the handle 2 and is fixed with a hook 901. Therefore, while holding the handle 2, the paper pusher 1 can be operated to push the paper stack. The index finger can pull the hook 901 to drive the linkage plate 8 vertically using the transmission rod 9, thereby driving the pressure plate 5 to move horizontally downward.

[0034] In specific implementation, a limiting groove 502 is formed in the middle of the upper end surface of the pressure plate 5, and the lower end of the linkage plate 8 is horizontally slidably placed in the limiting groove 502. Concave slideways are symmetrically formed on both sides of the bottom of the limiting groove 502, and limiting protrusions 801 are symmetrically fixed on both sides of the lower end of the linkage plate 8. The limiting protrusions 801 slide in cooperation with the slideways on both sides of the bottom of the limiting groove 502. Additionally, two mounting ears 802 are symmetrically fixed in the middle of the linkage plate 8, and the end of the transmission rod 9 is rotatably mounted between the two mounting ears 802.

[0035] The working principle of this utility model is as follows: When using the paper pressing device of the paper cutter, the operator holds the handle 2 of the paper pusher block 1 and presses the vertical outer side of the paper pusher block 1 tightly against the side edge of the paper stack to be cut. At this time, the pressure plate 5 is kept in an upward state under the pushing action of the return spring 7. The paper pusher block 1 moves horizontally along the worktable of the paper cutter, pushing the edge of the paper stack until it is tightly against the rear guard or side guard.

[0036] Once the paper stack is positioned, the operator does not need to release their hand or move the pusher block 1. Instead, they can directly use the index or middle finger of the same hand to horizontally pull the hook 901 at the end of the transmission rod 9. The pulling force is transmitted through the transmission rod 9, which passes through the column 3, to the mounting ear 802 in the middle of the linkage plate 8, driving the linkage plate 8 to rotate downward around its hinge point with the base plate 4. The limiting protrusion 801 at the lower end of the linkage plate 8 slides within the limiting groove 502 of the pressure plate 5, converting the horizontal pulling force into a vertical downward pushing force, forcibly pressing the pressure plate 5 to overcome the elastic force of the return spring 7 and move downward. The rubber pad 501 then presses against the surface of the paper stack, forming a downward pressure. At this time, the L-shaped structure of the pusher block 1 simultaneously maintains the lateral positioning of the paper stack, achieving bidirectional constraint of lateral pushing and downward pressure, completely eliminating the risk of displacement caused by manual removal.

[0037] In addition, after the paper is pressed, the operator releases the hook 901. The return spring 7 pushes the pressure plate 5 upward, and the linkage plate 8 retracts to the initial tilt angle guided by the upper limit slide groove 502 of the pressure plate 5. The entire reset process is performed without external force intervention, and the pressure plate 5 automatically detaches from the paper stack surface to avoid interfering with subsequent paper stack movement. Throughout the entire operation, the operator's hands remain within the safe zone of the paper pusher 1's handle 2 and the hook 901, maintaining a reliable distance from the paper cutter head.

[0038] In summary, this device not only allows for pressing down the paper stack during alignment, avoiding the problems of accuracy deviations and repeated adjustments caused by step-by-step operations, but also keeps the operator's hands away from the dangerous area of ​​the paper cutter head during operation, further improving the safety factor during operation. Overall, it has a good performance.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
