Description

Technical Field

[0001] This utility model belongs to the field of paper cutter technology, specifically relating to a paper cutter for printing. Background Technology

[0002] Paper cutters are traditional pieces of equipment primarily used to meet the needs of cutting printed paper. They can cut paper into suitable sizes and are an indispensable product in the printing industry. In current technology, after cutting one side of the paper, the operator needs to rearrange the paper, rotate it, and adjust it to the appropriate position to align with the cutter blade before cutting the other side. Therefore, when multiple sides of the paper need to be cut, the operator needs to manually repeat the above process, which is cumbersome, detrimental to work efficiency, and labor-intensive. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide a paper cutter for printing that can cut all four sides of a paper with just one placement during use, while keeping the paper pressed during the cutting process, thus effectively improving cutting accuracy and efficiency.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A paper cutter for printing, including

[0006] A base, on which a square working plate is fixedly installed at the top center, and the top of the square working plate is provided with four scale lines distributed in a rectangular pattern;

[0007] A U-shaped assembly block is fixedly installed at the top center of the base. A cylinder is fixedly installed on the top of the U-shaped assembly block. The telescopic end of the cylinder passes through the U-shaped assembly block and is fixedly connected to an assembly column. A pressing plate is fixedly installed at the bottom of the assembly column.

[0008] A rotating mechanism is provided on the upper side of the periphery of the assembly column;

[0009] A displacement mechanism, wherein the displacement mechanism is disposed around the periphery of the rotating mechanism;

[0010] A shearing mechanism is provided at the bottom of the displacement mechanism;

[0011] The controller is installed on the top front side of the base, and the rotating mechanism, displacement mechanism and cylinder are all electrically connected to the controller.

[0012] As a preferred technical solution, the rotating mechanism includes a circular block, which is rotatably mounted on the upper side of the periphery of the assembly column. The displacement mechanism is fixedly installed on the periphery of the circular block. A plurality of meshing teeth are arranged around the upper side of the circular block. An L-shaped assembly plate is fixedly installed on the upper side of the periphery of the assembly column. A first motor is fixedly installed on the side of the L-shaped assembly plate away from the assembly column. The output shaft of the first motor passes through the L-shaped assembly plate and is fixedly mounted with a gear. The plurality of meshing teeth mesh with the gear. The first motor is electrically connected to the controller.

[0013] As a preferred technical solution, the displacement mechanism includes a connecting block, which is fixedly installed on the periphery of the circular block. An assembly groove is provided on the upper side of the connecting block, and an opening connected to the assembly groove is provided on the left side of the connecting block. A slider is slidably assembled inside the assembly groove, and an electric push rod is provided on the top of the slider. The telescopic end of the electric push rod passes through the slider and is fixedly connected to the upper side of the shearing mechanism.

[0014] The connecting block has connecting plates arranged front and back on its left side. Two connecting plates are mounted on a threaded rod that rotates together on one side close to each other. A displacement block is threaded around the threaded rod. One side of the displacement block passes through an opening and is fixedly connected to the slider. A second motor is fixedly installed on the rear side of the connecting plate. The output shaft of the second motor is connected to the threaded rod.

[0016] As a preferred technical solution, a number of elastic telescopic rods are arranged horizontally on the front side of the bottom of the horizontal plate, and a stabilizing plate is fixedly installed at the lower end of the number of elastic telescopic rods.

[0017] The beneficial effects of this utility model are:

[0018] When in use, the linear laser emitter can accurately determine the position of the cutter.

Detailed Implementation

[0024] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-3 As shown, this utility model discloses a paper cutter for printing, comprising:

[0026] The base 1 has a square working plate 11 fixedly installed at the top center. The top of the square working plate 11 has four scale lines 12 arranged in a rectangle. The square working plate 11 is used to place the cutting paper, and the cutting length of the four sides of the cutting paper can be determined by referring to the four scale lines 12.

[0027] U-shaped assembly block 2, U-shaped assembly block 2 is fixedly installed at the top center of base 1, cylinder 21 is fixedly installed at the top of U-shaped assembly block 2, the telescopic end of cylinder 21 passes through U-shaped assembly block 2 and is fixedly connected to assembly column 22, and pressing plate 23 is fixedly installed at the bottom of assembly column 22.

[0028] Rotation mechanism 3 is located on the upper side of the periphery of assembly column 22. Specifically, rotation mechanism 3 includes a circular block 31, which is rotatably mounted on the upper side of the periphery of assembly column 22. Displacement mechanism 4 is fixedly installed on the periphery of circular block 31. Several meshing teeth 32 are arranged around the upper side of circular block 31. An L-shaped assembly plate 33 is fixedly installed on the upper side of the periphery of assembly column 22. A first motor 34 is fixedly installed on the side of L-shaped assembly plate 33 away from assembly column 22. The output shaft of the first motor 34 passes through L-shaped assembly plate 33 and is fixedly mounted with gear 35. Several meshing teeth 32 mesh with gear 35. The first motor 34 is electrically connected to controller 6.

[0029] In use, after the paper is placed, the controller 6 starts the cylinder 21. The telescopic end of the cylinder 21 drives the assembly column 22 to descend, ultimately causing the pressing plate 23 to contact the paper and press and fix the stacked paper to prevent it from shifting during cutting. Then, the controller 6 starts the displacement mechanism 4 and adjusts the position of the cutting mechanism 5, so that the cutting mechanism 5 moves to the appropriate position. The moving distance is compared with the four scale lines 12. Then, the cutting mechanism 5 is started to cut one edge of the paper. After one edge is cut, the first motor 34 is started. The first motor 34 drives the gear 35 to rotate. 5 drives the circular block 31 to deflect 90 degrees until it aligns with the other side of the paper. Repeating the above operation process allows for cutting the other side of the paper. This completes the cutting of all four sides of the paper. After cutting, control cylinder 21 to return to its initial state, and the paper can be removed. This operation can complete the cutting of all four sides of the paper sequentially, eliminating the need for multiple paper adjustments and the need to rotate the paper and manually readjust the cutting distance after adjustment. This effectively improves the work efficiency of the staff, and the staff's hands are kept away from the cutter 52 of the cutting mechanism 5, making it safer.

[0030] The displacement mechanism 4 is located around the rotating mechanism 3. Specifically, the displacement mechanism 4 includes a connecting block 41, which is fixedly installed around the circular block 31. An assembly groove 42 is provided on the upper side of the connecting block 41, and an opening 43 connected to the assembly groove 42 is provided on the left side of the connecting block 41. A slider 45 is slidably assembled inside the assembly groove 42. An electric push rod 46 is provided on the top of the slider 45. The telescopic end of the electric push rod 46 passes through the slider 45 and is fixedly connected to the upper side of the shearing mechanism 5.

[0031] Connecting plates 47 are mounted on the left side of connecting block 41 in a front-to-back arrangement. Two connecting plates 47 are mounted on a threaded rod 48 that rotates together on one side of each other. A displacement block 49 is threaded around the threaded rod 48. One side of the displacement block 49 passes through the opening 43 and is fixedly connected to the slider 45. A second motor 491 is fixedly installed on the rear side of the rear connecting plate 47. The output shaft of the second motor 491 is connected to the threaded rod 48 for transmission. The second motor 491 and the electric push rod 46 are both electrically connected to the controller 6.

[0032] When it is necessary to control the slider 45 to move, the controller 6 can control the output shaft of the second motor 491 to rotate forward or backward. The second motor 491 drives the threaded rod 48 to rotate forward or backward, and the displacement block 49 drives the slider 45 to move, thereby adjusting the cutting position. After adjusting to the set position, the extension end of the electric push rod 46 is controlled to move down, which drives the shearing mechanism 5 to move down to cut the paper. After the cutting is completed, the extension end of the electric push rod 46 is controlled to retract.

[0033] The shearing mechanism 5 is located at the bottom of the displacement mechanism 4. Specifically, the shearing mechanism 5 includes a horizontal plate 51, the upper side of which is fixedly connected to the telescopic end of the electric push rod 46. A cutter 52 is fixedly installed on the rear bottom side of the horizontal plate 51. A linear laser emitter 53 is obliquely assembled in the middle of the rear side of the horizontal plate 51. The linear laser emitter 53 is electrically connected to the controller 6.

[0034] The linear laser emitted by the linear laser emitter 53 is aligned with the lower end of the cutter 52. The linear laser extends and connects with the set scale line 12. Therefore, the operator can intuitively determine the position of the cutter 52 by the linear laser. When moving, the displacement amount can be directly input through the input terminal of the controller 6, and the cutter 52 can be moved by the displacement mechanism 4. The linear laser emitter 53 moves accordingly, and the cutting is performed after reaching the designated position.

[0035] The controller 6 is installed on the top front side of the base 1. The rotating mechanism 3, the displacement mechanism 4 and the cylinder 21 are all electrically connected to the controller 6.

[0036] Several elastic telescopic rods 54 are arranged horizontally on the bottom front side of the horizontal plate 51, and a stabilizing plate 55 is fixedly installed at the lower end of the elastic telescopic rods 54. Before cutting the paper, the stabilizing plate 55 will first contact the paper. The elastic telescopic rods 54 have springs inside. As the horizontal plate 51 continues to descend, the elastic telescopic rods 54 will retract and apply pressure to the paper, further increasing the cutting stability.

[0037] The device is used as follows:

[0038] In use, the stacked paper is placed on the square work plate 11. The required cutting area is determined by the four set scale lines and the linear laser emitted by the laser emitter 53. Then, the cylinder 21 is activated, which drives the pressing plate 23 to press down on the paper to fix and tighten it. Then, the displacement direction and displacement distance are input through the input terminal of the controller 6. The second motor 491 drives the threaded rod 48 to rotate, and then adjusts the slider 45 to move. After reaching the designated position, the electric push rod 46 is controlled to move down. The electric push rod 46 drives the cutter 52 to cut one side of the paper. After one side is cut, the controller 6 controls the first motor 34 to start. The first motor 34 drives the gear 35 to mesh with the meshing teeth 32, which drives the circular block 31 to rotate 90 degrees, which in turn drives the cutter 52 to rotate 90 degrees to align with the other side of the paper. The cutting process is repeated to cut the other side of the paper. During this process, the paper will be kept in a tight state to prevent displacement during cutting. In this way, the cutting of all four sides of the paper can be completed. After cutting, the paper can be removed.

[0039] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
