Description

Technical Field

[0001] This utility model relates to the field of sheet die-cutting technology, and in particular to a continuous sheet die-cutting machine. Background Technology

[0002] Sheet die is a key component of continuous sheet die-cutting machines. It resembles a mold and consists of blades, cutter holders, etc. Through precise design, it cuts on the sheet material to achieve a predetermined shape. It can accurately control the cutting depth, shape and size to ensure consistent product specifications and is widely used in sheet processing in industries such as packaging and electronics.

[0003] The basic structure of a continuous sheet die-cutting machine includes a feeding device, a die-cutting device, and a receiving device. During operation, the feeding device sends out the sheet material, and the die-cutting device cuts the sheet material under pressure to complete the processing of a specific shape. Afterward, the receiving device collects and sorts the finished product or waste material, realizing continuous automated production.

[0004] In existing technologies, some continuous sheet die-cutting machines, if not positioned during cutting, are prone to deviation in cutting position, resulting in inconsistent sheet sizes and inaccurate shapes. After cutting and extrusion, due to the lack of positioning during the initial cutting, the extrusion forming position will also be disordered, making it difficult for products to meet standards and producing a large number of defective products. This not only wastes materials but also increases costs, reduces production efficiency, and seriously affects product quality and corporate profits. Therefore, a continuous sheet die-cutting machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a continuous sheet die-cutting machine, which aims to improve the problem in the prior art that it is difficult to position the sheet film during cutting and that it is not possible to extrude the sheet film synchronously.

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

[0007] A continuous sheet die-cutting machine includes a conveyor. A support plate is fixedly connected to the top of the conveyor. A cylinder is fixedly connected to the bottom of the support plate.

[0012] As a further description of the above technical solution:

[0013] The front and rear ends of the support plate are fixedly connected to the locking rods, and the front and rear ends of the displacement rod are slidably connected to the near ends of the two locking rods respectively.

[0014] As a further description of the above technical solution:

[0015] The tensioning assembly includes two fixing plates. The bottoms of the two fixing plates are respectively fixedly connected to the front and rear ends of the top of the transmitter. A storage roller is fixedly connected to one end of the two fixing plates and a transmission roller is fixedly connected to one end of the two fixing plates.

[0016] As a further description of the above technical solution:

[0021] Both of the two fixed plates have grooves at their adjacent ends, and the sliders are slidably connected to the inside of the grooves. The two sliders are rotatably connected to the adjacent ends of the two sliders.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the cylinder can drive the slide plate to move downward, so that the cutter head can move.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a continuous sheet die-cutting machine, including a transmitter 1. A support plate 13 is fixedly connected to the top of the transmitter 1, providing a mounting base. A cylinder 14 is fixedly connected to the bottom of the support plate 13, supporting and fixing the position of the cylinder 14. A slide plate 15 is fixedly connected to the drive end of the cylinder 14, enabling the cylinder 14 to drive the slide plate 15 to move vertically up and down. Two limiting rods 16 are fixedly connected to the inner wall of the support plate 13, restricting the movement path of the slide plate 15 to a straight line. A cutter head 17 is fixedly connected to the bottom of the slide plate 15, and the position change of the slide plate 15 drives the cutter head 17 to cut. Sliding sleeves 18 are fixedly connected to both the front and rear ends of the cutter head 17, and the position change of the cutter head 17 can drive the position change of the sliding sleeves 18. A connecting rod 19 is slidably connected inside the sliding sleeves 18, and the position change of the sliding sleeves 18 can drive the position change of the connecting rod 19.

[0034] A spring 28 is sleeved on the outside of the connecting rod 19, and a positioning pad 20 is fixedly connected to the bottom of the connecting rod 19. When the positioning pad 20 contacts the transmitter 1, the sliding sleeve 18 compresses the spring 28, causing the spring 28 to deform and generate elastic potential energy, thereby achieving the positioning and cutting effect. Two connecting rods 21 are fixedly connected to the left side of the slide plate 15. When the slide plate 15 moves, it can drive the two connecting rods 21 to descend. A positioning box 23 is fixedly connected to the left side of the transmitter 1, and the positioning box 23 serves as a mounting box. A shaping box 22 is fixedly connected inside the positioning box 23. The shaping box 22 is designed for stamping sheet film.

[0035] An extrusion assembly for shaping the sheet film is fixedly connected to the left side of the two connecting rods 21. The extrusion assembly includes a displacement rod 25, the right side of which is fixedly connected to the left side of the two connecting rods 21. The position of the displacement rod 25 can be adjusted by changing the position of the two connecting rods 21. A pressing block 27 is fixedly connected to the bottom of the displacement rod 25. The position of the displacement rod 25 can be adjusted by changing the position of the pressing block 27, thereby extruding and shaping the sheet film. Support plates 24 are fixedly connected to the front and rear ends of the positioning box 23. The support plates 24 serve to install and support the internal structure. Locking rods 26 are fixedly connected to the front and rear ends of the support plates 24. The locking rods 26 serve to limit the movement of the displacement rod 25. The front and rear ends of the displacement rod 25 are slidably connected to the adjacent ends of the two locking rods 26. The two locking rods 26 can limit the movement of the displacement rod 25.

[0036] Reference Figure 2 , Figure 3 and Figure 5 The top front and rear ends of the transmitter 1 are fixedly connected to a tensioning assembly for pulling the sheet material mold. The tensioning assembly includes two fixed plates 2, the bottoms of which are fixedly connected to the top front and rear ends of the transmitter 1, respectively. The fixed plates 2 are used to install the internal tension adjustment structure. A storage roller 3 is fixedly connected to one of the adjacent ends of the two fixed plates 2, and the storage roller 3 is used to store the sheet material mold. A transmission roller 4 is fixedly connected to one of the adjacent ends of the two fixed plates 2, and the transmission roller 4 is used to transport the sheet material mold. A motor 5 is fixedly connected to the rear end of one of the fixed plates 2, and an eccentric wheel 7 is fixedly connected to the drive end of the motor 5, which drives the eccentric wheel 7 to rotate.

[0037] One of the fixed plates 2 has a stabilizing plate 6 fixedly connected to its inner top. The rear end of an eccentric wheel 7 is rotatably connected to the inside of the stabilizing plate 6, which supports the eccentric wheel 7. A linkage rod 8 is rotatably connected to the front end of the eccentric wheel 7, causing the linkage rod 8 to rotate in a circular motion as the eccentric wheel 7 rotates. A moving rod 9 is rotatably connected to the front end of the linkage rod 8, and a slider 10 is rotatably connected to the outside of the moving rod 9. The positional change of the linkage rod 8 causes the moving rod 9 and the slider 10 to move together. A sliding groove 12 is provided at the adjacent ends of both fixed plates 2. The outside of the slider 10 is slidably connected to the inside of the sliding groove 12, which restricts the movement of the slider 10 and prevents positional deviation during movement. An extrusion roller 11 is rotatably connected to the adjacent ends of the two sliders 10. The positional change of the slider 10 causes the extrusion roller 11 to move up and down, adjusting the tension of the sheet film.

[0038] Working principle: When the sheet material mold needs to be tensioned, the sheet material mold is first placed outside the fixed plate 2. Then, the motor 5 drives the eccentric wheel 7 to rotate, and the stabilizing plate 6 can limit the stability of the eccentric wheel 7 during rotation. When the eccentric wheel 7 rotates, it can drive the linkage rod 8 to move in a circular motion. When the linkage rod 8 moves in a circular motion, it can drive the moving rod 9 to move up and down, so that the slider 10 can slide inside the slide groove 12. When the slider 10 moves, it can drive the extrusion roller 11 to move up and down. When the sheet material mold is placed at the bottom of the extrusion roller 11, the tensioning effect can be achieved. Then, the sheet material is placed on the top of the transfer roller 4 to achieve the transfer function.

[0039] When the sheet film needs to be cut and stamped, the cylinder 14 is activated to push the slide plate 15 up and down, so that the slide plate 15 moves to the near end of the two limiting rods 16, thereby restricting the movement path of the slide plate 15. During the movement, the slide plate 15 can drive the cutter head 17 to cut. The position change of the cutter head 17 drives the position change of the sliding sleeve 18. The position change of the sliding sleeve 18 can drive the position change of the connecting rod 19. When the positioning pad 20 contacts the transmitter 1, the sliding sleeve 18 compresses the spring 28, causing the spring 28 to deform, thereby generating elastic potential energy, thus achieving the effect of positioning and cutting. When the slide plate 15 moves, it can drive the two connecting rods 21 to descend. The position change of the two connecting rods 21 can drive the displacement rod 25 to move. Then, the displacement rod 25 can drive the lower pressure block 27 to squeeze the sheet mold inside the shaping box 22, thereby achieving the shaping effect.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
