Description

Technical Field

[0001] This utility model relates to the technical field of paper product processing equipment, and in particular to a paper product cutting device. Background Technology

[0002] Paper products are a general term for products made from paper. They are used in various fields such as daily life, office, printing, packaging and decoration. The production process of paper products requires the use of cutting equipment to cut the paper products to achieve the required size and shape.

[0003] A search revealed a Chinese patent with patent number "CN221338641U" entitled "A Device for Preventing Rough Edge Cutting in Packaging," which describes a device comprising: "a support frame, a positioning mechanism on the top left side of the support frame, and cutting mechanisms on both sides of the bottom of the support frame. Each cutting mechanism includes support members, all fixedly connected to the bottom sides of the support frame. A threaded rod is rotatably connected between two of the support members. A sliding block is threaded onto the surface of the threaded rod. A second motor is fixedly connected to the top of the sliding block. Rotating rods are fixedly connected to both sides of the second motor." Both sides are fixedly connected with cutting blades, and both sides of the support frame have rectangular slots, in which the cutting blades are set. This solves the problem that "when cutting paper product packaging box rough edges, the device can only cut one side of the rough edge at a time. When the other side of the paper product needs to be cut, the worker needs to flip it over, which is time-consuming and labor-intensive, resulting in low efficiency in cutting rough edges on both sides of the paper product." However, it was found in use that the device can only cut paper products of the same width, and it is difficult to cut paper products of different widths and sizes, resulting in a large limitation in the use of the cutting device.

[0004] Therefore, how to provide a cutting device for paper products is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] refer to Figure 1-4 In this embodiment, the system includes a worktable 1, a reciprocating drive assembly 2, a dual-axis motor 3, and a cutting shear 4. The reciprocating drive assembly 2 is located at the bottom of the worktable 1. This assembly, a prior art component, drives the cutting shear 4 and the dual-axis motor 3 to reciprocate. A cutting slot 5 is provided on the surface of the worktable 1 at the position corresponding to the cutting shear 4. The cutting shear 4 is movably connected inside the cutting slot 5. A mounting plate 6 is provided on the reciprocating drive assembly 2, and is mounted on a reciprocating movable block within the assembly. Movement of the reciprocating movable block causes the mounting plate 6 to move. A fixing bracket 7 is fixedly connected to the top of the mounting plate 6. The mounting plate 6 is movably fitted onto the surfaces of the two output shafts of the dual-axis motor 3 via the fixing bracket 7, used to position the mounting bracket. This movable design aims to avoid affecting the normal rotation of the output shafts of the dual-axis motor 3. The fixing bracket 7 is movably fitted onto the two output shafts of the dual-axis motor 3. Figure 3 As shown, the dual-axis motor 3 includes two output shafts, and the number and position of the mounting brackets 7 match the number and position of the two output shafts on the dual-axis motor 3.

[0024] A connecting frame 8 is provided on the side of the dual-axis motor 3. One end of the connecting frame 8 is fixedly connected to the surface of the mounting plate 6. A telescopic adjustment component 9 is provided on the end face of the output shaft of the dual-axis motor 3. The other end of the telescopic adjustment component 9 is fixedly connected to the surface of the cutting shears 4. The telescopic adjustment component 9 includes a prism 11 and an adjustment cylinder 12. The prism 11 is fixedly connected to the end face of the output shaft of the dual-axis motor 3. The adjustment cylinder 12 is movably sleeved on the surface of the prism 11. The end of the adjustment cylinder 12 away from the dual-axis motor 3 is fixedly connected to the surface of the cutting shears 4. The prism 11 is a hexagonal prism 11. The hexagonal prism 11 is designed so that the adjustment cylinder 12 rotates synchronously when the prism 11 rotates. This design is not limited to hexagonal prism 11 and can also be other shapes. It is only necessary that the adjustment cylinder 12 rotates and stops synchronously with the prism 11 when the prism 11 rotates. The size and shape of the inner wall of the adjustment cylinder 12 match the size and shape of the prism 11. The matching design reduces the gap between the two and improves the stability of the connection.

[0025] The connecting frame 8 is equipped with a drive adjustment assembly 10 for moving the telescopic adjustment member 9. The drive adjustment assembly 10 includes a drive motor 13, a drive gear 14, a transmission gear 15, and an adjustment mechanism 16. The adjustment mechanism is designed to be parallel to the prism 11 and the adjustment cylinder 12. The drive motor 13 is fixedly connected to the surface of the connecting frame 8. The power supply method of the drive motor 13 is the same as that of the dual-axis motor 3. Moreover, the start and stop buttons of the drive motor 13 are located on the side of the workbench 1, which facilitates manual operation of the drive motor 13 by the operator. The drive gear 14 is fixedly connected to the output shaft of the drive motor 13, and the transmission gear 15 is located on the surface of the adjustment mechanism and is positioned opposite to the adjustment mechanism. At the axle, the connecting frame 8 is movably sleeved on the surface of the adjusting mechanism. The end face of the adjusting mechanism is set on the surface of the adjusting cylinder 12. The adjusting mechanism includes a rotating frame 17, a threaded tube 18, and a double-threaded screw 19. The surface of the double-threaded screw 19 is symmetrically provided with two sets of opposite threads. The threads in the two threaded tubes 18 are matched with the two sets of opposite threads on the double-threaded screw 19. The rotating frame 17 is rotatably sleeved on the surface of the adjusting cylinder 12 through the first rotating mechanism. The threaded tube 18 is fixedly connected to the surface of the rotating frame 17. The connecting frame 8 is rotatably sleeved on the surface of the double-threaded screw 19 through the second rotating mechanism. The transmission gear 15 is fixedly connected to the surface of the double-threaded screw 19. The threaded tube 18 is threadedly sleeved on the surface of the double-threaded screw 19.

[0026] During operation, the drive motor 13 needs to be started when the dual-axis motor 3 is paused. The rotation of the drive motor 13 will drive the drive gear 14 to rotate, which in turn will drive the transmission gear 15 to rotate. The rotation of the transmission gear 15 will drive the double threaded screw 19 to rotate. The stable rotation of the double threaded screw 19 on the connecting frame 8 will cause the two threaded tubes 18 to move closer or further apart. The movement of the two threaded tubes 18 will cause the two rotating frames 17 to move closer or further apart. The movement of the two rotating frames 17 will cause the two adjusting cylinders 12 at the two output shaft positions of the dual-axis motor 3 to move closer or further apart. The movement of the two adjusting cylinders 12 will cause the two cutting blades 4 to move closer or further apart. In this way, the distance between the two cutting blades 4 can be adjusted, thereby achieving the purpose of cutting paper products of different widths and sizes.

[0027] refer to Figure 1-4 In this embodiment, the surfaces of the prism 11 and the adjusting cylinder 12 are both provided with scales 26. The scales 26 allow the adjustment of the spacing between the two cutting scissors 4 to be seen at a glance, thereby improving the accuracy of the spacing adjustment between the two cutting scissors 4.

[0028] refer to Figure 1-4 In this embodiment, each group of the first rotating mechanism includes two sets of first conical fixed rings 20, two sets of first conical bearings 21, and one conical rotating ring 22. The two sets of first conical fixed rings 20 are fixedly sleeved on the surface of the adjusting cylinder 12. The two sets of first conical bearings 21 are respectively fixedly connected to the opposite surfaces of the two sets of first conical fixed rings 20. The conical rotating ring 22 is fixedly sleeved on the surface of the two sets of first conical bearings 21, and the conical rotating ring 22 is located between the two sets of first conical fixed rings 20. Each group of the second rotating mechanism includes two sets of second conical fixed rings 23, two sets of second conical bearings 24, and one convex ring 25. The two sets of second conical fixed rings 23 are all connected to the inner wall of the connecting frame 8, and the two sets of second conical bearings 24 are respectively fixedly connected to the inner side of the two sets of second conical fixed rings 23. On one side, a convex ring 25 is fixedly connected to the inner side of two sets of second conical bearings 24, and the convex ring 25 is located between two sets of second conical fixed rings 23. It should be noted that when the two rotating frames 17 move, they will drive the two sets of first conical bearings 21 and the two sets of first conical fixed rings 20 to move synchronously through the conical rotating ring 22. The two sets of first conical fixed rings 20 are conical in design and fixed on the surface of the adjusting cylinder 12. In this way, when the conical rotating ring 22 moves, it will squeeze the first conical fixed ring 20 through the first conical bearing 21. The conical design prevents the conical rotating ring 22 from being misaligned with the first conical fixed ring 20 when it moves. The purpose of the first conical bearing 21 is to make the adjusting cylinder 12 rotate more smoothly and stably. The function of the second rotating mechanism is the same as that of the first rotating mechanism.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
