Description

Technical Field

[0001] This utility model relates to the field of composite film cutting technology, and in particular to a cutting device for composite film production. Background Technology

[0002] Currently, composite films are thin films made by combining two or more different materials through a specific process. They typically possess the combined properties of multiple materials, such as high strength, good barrier properties, water resistance, and chemical resistance. They are widely used in various fields such as food, medicine, electronics, and packaging to meet the diverse needs of different application scenarios for material performance.

[0003] A PA composite film cutting device is disclosed in Chinese utility model patent with announcement number CN219095220U. Although the above-mentioned prior art can enable the limiting plate to limit the composite film of different diameters, the factory production line basically does not stop, that is, the cutting device will perform continuous cutting for a long time. Under high-intensity cutting work, the cutting blade will become dull due to the excessive number of cuttings. The cutting blade needs to be replaced when it becomes dull. Currently, the replacement of the blade is relatively cumbersome, and the cutting machine needs to be stopped for a long time when replacing it, which affects the production efficiency of the production line. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cutting device for composite film production.

[0005] This utility model is achieved using the following technical solution: a cutting device for composite film production, including a cutting table, an unwinding assembly for unwinding composite film on the cutting table, a cutting assembly for cutting the unwinding composite film on one side of the unwinding assembly, and a replacement assembly for quickly changing the cutting blade on the cutting assembly. The device includes a support frame fixedly installed on the top of the cutting table in a concave shape, two push cylinders fixedly installed on the top of the support frame, and mounting plates fixedly installed through the push ends of the two push cylinders downward through the support frame. A blade groove is opened on one side of the mounting plate, and a cutting blade is provided inside the blade groove.

[0006] With the above technical solution, when the cutting blade becomes dull and needs to be replaced, simply contact the fixing effect of the replacement component, then remove the replacement component from the top, and the cutting blade can be removed together. Then, install the replacement blade onto the replacement component, and finally install the replacement component back on the top and fix it. This setup allows workers to quickly replace the cutting blade, avoiding wasting too much production line time.

[0007] As a further improvement to the above solution, the replacement component includes a fixing plate disposed on the blade groove. Multiple limiting posts are fixedly installed on one side of the fixing plate. Multiple limiting holes are opened on the cutting blade. Multiple fixing holes are opened on the inner wall of the blade groove. One end of each limiting post passes through the adjacent limiting hole and extends into the interior of the adjacent fixing hole.

[0008] With the above technical solution, the cutting blade can move together with the fixing plate when it is hung on the limiting post. In this way, when the fixing plate is removed from the mounting plate, the cutting blade will also be removed together.

[0009] As a further improvement to the above solution, each of the limiting posts has a limiting groove on its cylindrical surface, and each of the limiting posts is engaged with the cutting blade through the limiting groove and the limiting hole.

[0010] With the above technical solution, when the cutting blade is hung on the limiting post, the limiting hole will be locked inside the limiting groove, preventing the cutting blade from shaking on the limiting post.

[0011] As a further improvement to the above solution, the inner walls at both ends of the blade groove are provided with fixing grooves, and the two ends of the fixing plate are fixedly installed with limiting plates, and the two limiting plates are located inside the adjacent fixing grooves.

[0012] By using the above technical solution, the insertion of the limiting plate into the fixing slot can prevent the fixing plate from falling down and failing to be fixed inside the blade slot of the mounting plate.

[0013] As a further improvement to the above solution, two first push rods are provided on one side of the fixing plate. The two first push rods are rotatably engaged at their close ends, and a second push rod is rotatably installed at the two far ends of the two first push rods. Fixing blocks are fixedly installed at both ends of the mounting plate on the side close to the first push rods. A slot is opened on the side of the two fixing blocks that are close to each other. One end of each second push rod extends into the interior of the adjacent slot.

[0014] With the above technical solution, when the first push rod is laid flat, it will push the second push rods on both sides, so that one end of the two second push rods is inserted into the slot of the fixing block, thus fixing the position of the fixing plate.

[0015] Lifting the two first push rods will pull back the two second push rods, causing them to be pulled out of the slots of the fixing block. This releases the fixing plate from its fixed state, allowing it to be removed from the mounting plate.

[0016] As a further improvement to the above solution, each of the second push rods is fitted with a concave limiting plate, and each limiting plate is fixedly installed with the fixing plate.

[0017] The above technical solution prevents the second push rod from deviating, allowing it to move only horizontally.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention, through the setting and replacement of components, allows for quick replacement of the cutting blade when it becomes dull. Simply release the fixing effect of the replacement component, remove the replacement component from the top, and the cutting blade can be removed along with it. Then, install the replacement blade onto the replacement component, and finally install the replacement component back on and fix it in place. This design allows workers to quickly replace the cutting blade, avoiding excessive production line time wasted. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Please combine Figures 1-4This embodiment of a cutting device for producing composite film includes a cutting table 1, an unwinding assembly 2 for unwinding composite film on the cutting table 1, a cutting assembly for cutting the unwinding composite film on one side of the unwinding assembly 2, and a replacement assembly for quickly changing the cutting blade on the cutting assembly. The device includes a support frame 301 fixedly installed on the top of the cutting table 1 in a concave shape, two push cylinders 302 fixedly installed on the top of the support frame 301, and mounting plates 303 fixedly installed on the push ends of the two push cylinders 302 through the support frame 301. A blade groove is opened on one side of the mounting plate 303, and a cutting blade 304 is provided inside the blade groove.

[0028] When the cutting blade 304 becomes dull and needs to be replaced, simply contact the fixing mechanism of the replacement component, then remove the replacement component from the top. The cutting blade 304 can then be removed together with the replacement component. Next, install the replacement blade onto the replacement component, and finally install the replacement component back onto the top. This setup allows workers to quickly replace the cutting blade 304, avoiding excessive production line time wasted.

[0029] The replacement component includes a fixing plate 401 set on the blade groove. Multiple limiting posts 402 are fixedly installed on one side of the fixing plate 401. Multiple limiting holes are opened on the cutting blade 304. Multiple fixing holes are opened on the inner wall of the blade groove. One end of each limiting post 402 passes through the adjacent limiting hole and extends into the interior of the adjacent fixing hole. A limiting groove is opened on the cylindrical surface of each limiting post 402. Each limiting post 402 is engaged with the cutting blade 304 through the limiting groove and the limiting hole.

[0030] The cutting blade 304 can move together with the fixing plate 401 when it is hung on the limiting post 402. When the fixing plate 401 is removed from the mounting plate 301, the cutting blade 304 will also be removed. The cutting blade 304 hanging on the limiting post 402 will make the limiting hole lock inside the limiting groove, preventing the cutting blade 304 from shaking on the limiting post 402.

[0031] The inner walls at both ends of the blade groove are provided with fixing grooves, and the two ends of the fixing plate 401 are fixedly installed with limiting plates 5, and the two limiting plates 5 are located inside the adjacent fixing grooves.

[0032] The limiting plate 5 is inserted into the fixing groove to prevent the fixing plate 401 from falling and failing to be fixed inside the blade groove of the mounting plate 303.

[0033] Two first push rods 6 are provided on one side of the fixing plate 401. The ends of the two first push rods 6 that are close to each other are rotatably engaged, and the ends of the two first push rods 6 that are far apart are rotatably mounted with second push rods 7. Fixing blocks 8 are fixedly installed on both ends of the mounting plate 303 that are close to the first push rods 6. The sides of the two fixing blocks 8 that are close to each other are provided with slots. One end of each second push rod 7 extends into the interior of the adjacent slot. Each second push rod 7 is fitted with a concave limiting plate 9. Each limiting plate 9 is fixedly installed with the fixing plate 401.

[0034] When the first push rod 6 is laid flat, it will push the two second push rods 7 on both sides, so that one end of the two second push rods 7 is inserted into the slot of the fixing block 8, thus fixing the position of the fixing plate 401.

[0035] Lifting the two first push rods 6 will pull back the two second push rods 7, causing the second push rods 7 to be pulled out of the slots of the fixing block 8. This will release the fixing state of the fixing plate 401, allowing the fixing plate 401 to be removed from the mounting plate 303.

[0036] The limiting plate 9 prevents the second push rod 7 from deviating, allowing the second push rod 7 to move only horizontally.

[0037] The implementation principle of a cutting device for composite film production in this application embodiment is as follows: In the initial state, the two first push rods 6 and the two second push rods 7 are all on the same horizontal line, so that one end of the two second push rods 7 is inserted into the slot of the adjacent fixed block 8.

[0038] When the cutting blade 304 becomes dull and needs to be replaced, pull up the part where the two first push rods 6 are connected. This will cause the two first push rods 6 to rotate and move closer together around the connection point. As the two first push rods 6 move closer together, the distance between the two second push rods 7 will be shortened. This will cause the two second push rods 7 to be pulled closer together by the two first push rods 6. After the two second push rods 7 move, the end inserted into the slot of the fixing block 8 will be pulled out of the slot, so that the fixing plate 401 can be pulled out of the blade slot.

[0039] After the fixing plate 401 is pulled out, the cutting blade 304 is locked in the limiting groove of the limiting post 402 through the limiting hole. Therefore, the cutting blade 304 will also be pulled out along with the fixing plate 401. Then, you only need to lift the cutting blade 304 to remove it from the limiting post 402 for replacement, making the replacement more convenient.

[0040] After the cutting blade 304 is replaced, simply align the limiting plates 5 at both ends of the fixing plate 401 with the fixing slots of the mounting plate 303 and insert them. Then, the fixing plate 401, the limiting post 402, and the cutting blade 304 can be placed inside the blade slot. Finally, press down the two first push rods 6 to the horizontal position, which will allow one end of the two second push rods 7 to be inserted into the slots of the adjacent fixing blocks 8. In this way, the position of the fixing plate 401 will be completely fixed, and the cutting blade 304 will be fixed in place and will not shake.

[0041] This setup allows for easy replacement of the cutting blade 304 in just a few simple steps, avoiding the cumbersome process of replacing the original cutting blade 304 and its impact on production line efficiency.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
