Description

Technical Field

[0001] This utility model relates to the field of paper cutting technology, specifically to a paper cutting device for papermaking. Background Technology

[0002] Paper products refer to various products made primarily from paper (or cardboard) through processes such as cutting, folding, printing, pasting, and die-cutting, and used for specific purposes.

[0003] For example, patent document CN212578672U, entitled "A Paper Cutting Device for Papermaking Production," includes a base plate and a limiting base. Two fixed frames, each C-shaped, are fixedly connected to both sides of the top of the base plate. A driving wheel and a driven wheel are rotatably connected between the two fixed frames. A conveyor belt is fitted around the driving wheel and the driven wheel. A single cutting device is fixedly connected to the top of the two fixed frames. The paper on the conveyor belt is lifted by the bevel of the cutting base and passes through the top of the cutting base. The piston rod of the cylinder descends, pushing the third fixed plate downwards. After the anti-slip plate contacts the paper, it compresses the second spring, and the cutter enters the interior of the cutting base, thus cutting the paper.

[0004] However, in the paper cutting process described in the above literature, when the operator needs to switch to different edges of the paper, such as long edges, short edges, or oblique edges, the paper needs to be manually moved and repositioned. This not only consumes manpower but also prolongs the preparation time for cutting different edges of the same batch of paper at a time. As a result, it is impossible to adjust the placement angle of the paper in real time according to the position of the edge to be cut, thereby reducing the paper cutting efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a paper cutting device for papermaking, which solves the technical problem mentioned in the background art of the inability to adjust the paper's placement angle in real time according to the position of the edge to be cut, thereby reducing the paper cutting efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A paper cutting device for papermaking includes a support frame, a mounting frame fixedly mounted on the top of the support frame, a cutting component for cutting paper on the mounting frame, a movable plate disposed inside the support frame, a driving component for moving the movable plate horizontally on the support frame, a placement plate disposed on the top of the movable plate, a rotating shaft rotatably disposed on the top of the movable plate, a placement plate fixedly disposed on the top of the rotating shaft, a driven gear fixedly disposed at the bottom end of the rotating shaft, a first motor fixedly disposed at the bottom of the movable plate, and a driving gear meshing with the driven gear fixedly disposed at the output end of the first motor.

[0008] Furthermore, the cutting assembly includes a cylinder fixedly mounted on the top of the mounting bracket and a cutter fixedly mounted on the output end of the cylinder.

[0009] Furthermore, the drive assembly includes a second motor fixedly mounted on the support frame and a threaded rod and a guide rod rotatably mounted within the support frame. The threaded rod and the guide rod are both arranged along the length direction of the support frame, and the threaded rod is threadedly connected to the moving plate, while the guide rod is slidably connected to the moving plate. The output end of the second motor is coaxially and fixedly connected to the threaded rod.

[0010] Furthermore, a connecting plate is fixedly installed on the top of the mounting bracket, a first electric push rod is fixedly installed on the connecting plate, and a pressure plate is fixedly installed on the output section of the first electric push rod.

[0011] Furthermore, the bottom of the pressure plate is evenly provided with grooves, and ball bearings are rotatably arranged in the grooves.

[0012] Furthermore, the mounting bracket is fixedly provided with two symmetrically arranged second electric push rods, and the output end of the second electric push rod is fixedly provided with a push plate.

[0013] The beneficial effects of this utility model are as follows: By setting up a placement plate, a rotating shaft, a driven gear, a first motor, and a driving gear, when it is necessary to cut different edges of the paper, the first motor is started, and the first motor drives the driving gear to rotate, which in turn drives the driven gear and the connected rotating shaft to rotate. The rotating shaft then drives the placement plate and the paper to rotate synchronously. Once the paper is adjusted to a suitable placement angle, this operation does not require manual handling and adjustment of the paper's position, shortening the preparation time for cutting different edges of the same batch of paper at a time. Thus, the angle of the paper can be adjusted in real time according to the position of the edge to be cut, improving the work efficiency when cutting different edges of the paper.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-3 As shown, a paper cutting device for papermaking includes a support frame 1, with support columns 2 evenly fixedly installed at the bottom of the support frame 1. A mounting frame 3, which is inverted "U"-shaped, is fixedly installed on the top of the support frame 1. The mounting frame 3 is equipped with a cutting assembly for cutting paper, including a cylinder 4 fixedly installed on the top of the mounting frame 3 and a cutter 6 fixedly installed at the output end of the cylinder 4. The cylinder 4 is vertically arranged, with its output end penetrating downwards through the mounting frame 3. A mounting plate 5 is fixedly installed at the output end of the cylinder 4. A mounting groove is formed along the length of the bottom of the mounting plate 5, and the top of the cutter 6 is inserted into the mounting groove and fastened to the mounting plate 5 by bolts. When replacing the cutter 6, the bolts can be removed first, and then the cutter 6 can be disassembled.

[0020] A movable plate 7 is installed inside the support frame 1, with its two sides slidably connected to the support frame 1. The support frame 1 is equipped with a drive assembly for moving the movable plate 7 horizontally. The drive assembly includes a second motor 8 fixedly installed in the support frame 1 and a threaded rod 9 and a guide rod 10 rotatably installed within the support frame 1. Both ends of the threaded rod 9 are smooth sections, and both ends rotatably pass through the support frame 1. The threaded rod 9 and the guide rod 10 are both arranged along the length of the support frame 1. The threaded rod 9 passes through the movable plate 7 and is threadedly connected to it, while the guide rod 10 passes through the movable plate 7 and is slidably connected to it. The output end of the second motor 8 passes through the support frame 1 and is coaxially fixedly connected to the threaded rod 9. When the second motor 8 is started, it drives the threaded rod 9 to rotate, which in turn moves the movable plate 7 along the length of the support frame 1.

[0021] A placement plate 11 is mounted on the top of the movable plate 7. A rotating shaft 12 is rotatably mounted at the top center of the movable plate 7. The placement plate 11 is fixedly mounted on the top of the rotating shaft 12. The bottom end of the rotating shaft 12 extends to the bottom of the movable plate 7 and is fixedly fitted with a driven gear 13. A first motor 14 is fixedly mounted on the bottom of the movable plate 7. A driving gear 15 that meshes with the driven gear 13 is fixedly mounted on the output end of the first motor 14. To meet the production requirements of cutting paper at different edges, the paper is placed on the placement plate 11, and the first motor 14 is started. The first motor 14 drives the driving gear 15 to rotate, which in turn drives the driven gear 13 and the connected rotating shaft 12 to rotate. The rotating shaft 12 then synchronously drives the placement plate 11 and the paper to rotate. After the paper is adjusted to a suitable placement angle, the first motor 14 stops working. This operation eliminates the need for manual repositioning of the paper, shortens the preparation time for a single cut of the same batch of paper, and allows for real-time adjustment of the paper angle according to the position of the edge to be cut, thus improving the work efficiency when cutting paper at different edges.

[0022] Mounting frame 3 is fixedly equipped with two symmetrically arranged second electric push rods 16. Both second electric push rods 16 are horizontally arranged, and their output ends pass through mounting frame 3 and are fixedly mounted with push plates 17. When the moving plate 7 conveys paper between the two push plates 17 via the placement plate 11, the two second electric push rods 16 start synchronously, driving the two push plates 17 to move towards each other and centering the paper, which helps improve the accuracy of subsequent cutting by the cutter 6. If cutting stacked paper, after the two push rods center and align the paper laterally, the two second electric push rods 16 retract, and the placement plate 11 rotates 90 degrees to switch the alignment direction of the paper. The two second electric push rods 16 are then started again to center and align the paper longitudinally, thus ensuring the consistency of cutting stacked paper.

[0023] A connecting plate 18 is fixedly installed on the top of the mounting frame 3, and a first electric push rod 19 is fixedly installed on the bottom of the connecting plate 18. A pressure plate 20 is fixedly installed on the output section of the first electric push rod 19. The bottom of the pressure plate 20 has evenly spaced grooves, and ball bearings 21 are rotatably installed within these grooves. After the paper is centered and aligned, the first electric push rod 19 is activated, which drives the pressure plate 20 downwards and presses the paper to prevent displacement during cutting and ensure cutting quality. Because the grooves of the pressure plate 20 contain ball bearings 21, when the paper needs to be rotated for edge cutting, the ball bearings 21 effectively reduce the friction between the pressure plate 20 and the paper, thus eliminating the need to move the pressure plate 20 upwards. This reduces operational steps and prevents misalignment of stacked paper during rotation.

[0024] Working principle:

[0025] When in use, place the paper on the placement plate 11, start the second motor 8, the second motor 8 drives the threaded rod 9 to rotate, the rotation of the threaded rod 9 drives the moving plate 7 to move along the length of the support frame 1. When the paper moves between the two push plates 17, the two second electric push rods 16 start synchronously, drive the two push plates 17 to move towards each other and push the paper to be centered and aligned.

[0026] After aligning the paper, activate the first electric push rod 19, which will move the pressure plate 20 downwards and press the paper to prevent it from shifting during cutting and ensure cutting quality. Then, activate the cylinder 4 to move the cutter 6 downwards to cut the paper.

[0027] When it is necessary to cut different edges of the paper, the first motor 14 is started. The first motor 14 drives the drive gear 15 to rotate, which in turn drives the driven gear 13 and the connected rotating shaft 12 to rotate. The rotating shaft 12 then synchronously drives the placement plate 11 and the paper to rotate. After the paper is adjusted to a suitable placement angle, the first motor 14 stops working. This operation eliminates the need for manual handling and readjustment of the paper, shortening the preparation time for cutting different edges of the same batch of paper at once. It also allows for real-time adjustment of the paper angle according to the position of the edge to be cut, improving the efficiency of cutting different edges of the paper.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
