Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, specifically a paper cutter for packaging box production. Background Technology

[0002] Packaging boxes are various containers or wrappers used to hold, protect, and display goods. Common materials include paper, plastic, metal, glass, and wood, and they come in a variety of shapes and forms. They not only prevent damage to goods during transportation and storage, but also convey brand image and attract consumers through design. They are also convenient for consumers to carry and use, serving as an important medium connecting goods and consumers. Packaging boxes are widely used in almost all industries, including food, cosmetics, electronics, and gifts.

[0003] In existing technology, the paper-fixing method of paper cutters used in packaging box production is pneumatic paper pressing. It uses several pneumatic press feet set under the cutter head or on both sides of the worktable. When the paper to be cut is placed in the designated position on the worktable, compressed air drives the press feet to quickly press down on the surface of the cardboard when the equipment is started. The friction generated by the pressure restricts the displacement of the cardboard during the cutting process.

[0004] For packaging box cardboard of different specifications, the position and number of pneumatic presser feet are usually fixed, which makes it difficult to flexibly adapt to all sizes of cardboard. If the cardboard size exceeds the coverage of the presser feet or the presser feet are not distributed reasonably, local insufficient fixation is likely to occur. The pressure of multiple pneumatic presser feet is easily affected by the stability of the air source, pipeline resistance, etc., which may result in inconsistent pressure of each presser foot, leading to uneven local stress on the cardboard, which in turn affects the cutting accuracy and makes it impossible to fix the paper efficiently. To address the above problems, a paper cutter for packaging box production is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a paper cutter for packaging box production, which solves the problem of the inability to efficiently fix paper in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper cutter for packaging box production, comprising a base frame, brackets fixedly connected to both sides of the top of the base frame, hydraulic cylinders fixedly connected to both sides of the top of the brackets, a fixed plate fixedly connected to the output end of the hydraulic cylinders, a servo motor fixedly connected to one side of the middle of the top of the brackets, a first gear fixedly connected to the output end of the servo motor, a second gear passing through and rotatably connected to the middle of the top of the brackets, and the second gear meshing with the first gear, a limit rod passing through and slidably connected to the top of the second gear, a first bevel gear set fixedly connected to the bottom of the limit rod, a bidirectional threaded rod passing through and rotatably connected to the middle of the inner wall of the fixed plate, and the first bevel gear set fixedly connected to the middle of the outer ring of the rear bidirectional threaded rod, and a second bevel gear set fixedly connected to one side of the outer ring of the bidirectional threaded rod.

[0007] By adopting the above technical solution, the hydraulic cylinder and motor inside the paper cutter can be easily controlled by an external controller. The limit rod and the second gear have a splined connection, so that the rotation of the second gear drives the limit rod to rotate synchronously, and the limit rod can slide up and down at the second gear.

[0008] As a further description of the above technical solution: a first lead screw is fixedly connected to one end of the second bevel gear set, and a fixing block is provided on the outer ring of both the bidirectional threaded rod and the first lead screw, and a transmission component is provided on the other side of the outer ring of the bidirectional threaded rod.

[0009] By adopting the above technical solution, the transmission assembly contains two sprockets and a chain, which enables the two bidirectional threaded rods to rotate synchronously.

[0010] As a further description of the above technical solution: a fixing rod is slidably connected through the top of the fixing block, and a pressure block is fixedly connected to the bottom of the fixing rod.

[0011] By adopting the above technical solution, the pressure block can fix the four corners of the paper.

[0012] As a further description of the above technical solution: a first spring is fixedly connected to the top of the pressure block, and the top of the first spring is fixedly connected to the fixing block.

[0013] By adopting the above technical solution, the first spring acts as a buffer when the pressure block moves downward.

[0014] As a further description of the above technical solution: a sliding rod is connected through and fixedly connected to the other side of the front end of the fixing plate, and a third lead screw is connected through and rotatably connected to one side of the front end of the fixing plate.

[0015] By adopting the above technical solution, a knob is provided at one end of the third lead screw to facilitate the rotation of the third lead screw.

[0016] As a further description of the above technical solution: the outer ring of the third lead screw and slide bar is provided with a slider, and the bottom of the slider is fixedly connected to a frame.

[0017] By adopting the above technical solution, the rotation of the third lead screw can cause the slider to move, and the slider provides stability for the movement of the frame.

[0018] As a further description of the above technical solution: a second spring is fixedly connected to the inner wall of the frame, and a cutting tool is fixedly connected to the bottom of the second spring.

[0019] By adopting the above technical solution, the second spring can play a buffering role during the downward movement of the cutter.

[0020] As a further description of the above technical solution: a cutting plate is fixedly connected to the middle of the top of the base frame.

[0021] By adopting the above technical solution, a cutting groove is opened on the cutting plate, and the position of the tool can be changed according to different needs.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a paper cutter for packaging box production. Firstly, through a linkage structure of a bidirectional threaded rod, a first lead screw, and fixed blocks, four fixed blocks can move simultaneously inwards or outwards, flexibly adjusting the fixing range to cut paper of different sizes, greatly expanding the applicability of the equipment. The pressure block, through a sliding design of the fixed rod and a first spring buffer, first makes soft contact with the paper and then gradually presses it down, avoiding rigid impact that could cause paper displacement. During cutting, the blade is buffered by a second spring and cuts slowly, ensuring the paper remains stable throughout the cutting process, significantly improving cutting accuracy and resulting in neat and regular cuts that meet the quality requirements of packaging box production. It can cut multiple stacked sheets of paper simultaneously, significantly improving production efficiency, effectively increasing the production rate of packaging boxes, and reducing time costs. After the fixed plate moves to its limit position and completes the cutting, the pressure release of the first and second springs effectively prevents paper from adhering to the pressure block or blade, reducing subsequent cleaning and material waste.

[0028] Reference Figure 2 — Figure 4The base frame 1 has brackets 2 fixedly connected to both sides of its top. Hydraulic cylinders 3 are fixedly connected to both sides of the top of brackets 2. A fixed plate 4 is fixedly connected to the output end of each hydraulic cylinder 3. The hydraulic cylinders 3 are controlled by an external controller, simultaneously driving the fixed plate 4 to move upwards or downwards. A servo motor 5 is fixedly connected to one side of the top center of bracket 2. A first gear 6 is fixedly connected to the output end of the servo motor 5, allowing the servo motor 5 to drive the first gear 6 to rotate forwards or backwards. A second gear 7 is rotatably connected through the top center of bracket 2, meshing with the first gear 6. Through the meshing of the gears, the... The rotation of the first gear 6 drives the second gear 7 to rotate synchronously. A limit rod 8 is slidably connected to the top of the second gear 7, and there is a limiting fit between the second gear 7 and the limit rod 8, so that the rotation of the second gear 7 drives the limit rod 8 to rotate synchronously. A first bevel gear set 9 is fixedly connected to the bottom of the limit rod 8, and the limit rod 8 drives the driving bevel gear to rotate. A bidirectional threaded rod 10 is rotatably connected through the middle of the inner wall of the fixed plate 4, and the first bevel gear set 9 is fixedly connected to the middle of the outer ring of the rear bidirectional threaded rod 10. The driven bevel gear drives the rear bidirectional threaded rod 10 to rotate. A second bevel gear set 11 is fixedly connected to one side of the outer ring of the rod 10. The second bevel gear set 11 contains two bevel gears that mesh with each other. A first lead screw 12 is fixedly connected to one end of the second bevel gear set 11. Through the meshing between the bevel gears, the relative first lead screws 12 rotate in opposite directions. Both the outer rings of the bidirectional threaded rod 10 and the first lead screw 12 are provided with fixing blocks 14. The rotation of the bidirectional threaded rod 10 and the first lead screw 12 can cause the fixing blocks 14 to move inward or outward simultaneously. A transmission assembly 18 is provided on the other side of the outer ring of the bidirectional threaded rod 10. Through the transmission assembly 18, the two bidirectional threaded rods 10 and the first lead screw 12 rotate in opposite directions. The threaded rod 10 rotates synchronously in the same direction. A fixed rod 15 is slidably connected through the top of the fixed block 14. The fixed block 14 fixes the position of the fixed rod 15 to prevent the fixed rod 15 from moving too far downward. A pressure block 16 is fixedly connected to the bottom of the fixed rod 15. The pressure block 16 can press the top of the paper and fix the position of the paper. A first spring 17 is fixedly connected to the top of the pressure block 16, and the top of the first spring 17 is fixedly connected to the fixed block 14. The first spring 17 plays a buffering role, and the pressure release of the first spring 17 can reset the fixed block 14.

[0029] Working principle: First, by rotating the third lead screw 20, the slider 19 moves the frame 21 and the cutter 23 to the corresponding cutting groove. Then, the stacked paper is placed on the cutting plate 24, and the stacking height should not exceed the cutting height of the cutter 23, so that the cutting line is aligned with the cutting groove. Then, the servo motor 5 drives the first gear 6 to rotate, and the second gear 7 drives the limit rod 8 to rotate through the meshing of the gears. The rotation of the limit rod 8 drives the first bevel gear set 9 at the top to transmit power. Then, the transmission assembly 18 causes the two bidirectional threaded rods 10 to rotate synchronously. The rotation of the bidirectional threaded rods 10 drives the first lead screw 12 to rotate through the transmission of the second bevel gear set 11. Through the meshing of the bevel gears, the relative first lead screws 12 rotate in opposite directions, so that the four fixed blocks 14 can move inward or outward simultaneously. When the paper is in the correct position, the hydraulic cylinder 3 drives the fixing plate 4 downwards. The pressure block 16 first contacts the topmost piece of paper, and then slides on the fixing block 14 via the fixing rod 15, causing the pressure block 16 to slowly press downwards. The first spring 17 provides cushioning and initial fixation. Then, the fixing plate 4 continues to move downwards, fixing the paper with the pressure block 16. After the pressure block 16 contacts the paper, the cutter 23 slowly moves downwards and cuts the paper. The second spring 22 provides cushioning to ensure stable cutting efficiency. When the fixing plate 4 moves to its limit position, the cutter 23 enters the cutting groove to cut the paper. The pressure release of the first spring 17 and the second spring 22 prevents paper from adhering, thus enabling the fixing and cutting of papers of different sizes. Stability is maintained throughout the cutting process, and multiple papers can be cut simultaneously.
