[0002] In the film production and processing, to ensure the edge quality of the film and the accuracy of subsequent processing, it is usually necessary to use an edge trimming device to cut the edges of the film. However, existing traditional film edge trimming devices have many shortcomings in practical applications and are difficult to meet the needs of efficient and precise production.

[0003] However, the traditional device has a cumbersome adjustment method for adjusting the distance and height between the blades, and lacks an integrated adjustment structure. Operators need to adjust each blade individually, which is not only complicated and time-consuming, but also makes it difficult to ensure that the distance adjustment accuracy between multiple blades is consistent. In order to solve the above problems, the inventors have proposed a thin film cutting device. Utility Model Content

[0019] 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.

[0020] Example: Figure 1-4As shown, this utility model provides a film trimming device, including a mounting frame 1. A first conveyor roller 2 and a second conveyor roller 3 are rotatably connected between the inner walls of the mounting frame 1. A rotating rod 4 is rotatably connected between the inner walls of the mounting frame 1 and above the second conveyor roller 3. Cutting discs 5 are provided on the outer sides of both ends of the rotating rod 4. A horizontal adjustment component 6 is provided inside the mounting frame 1 near the rotating rod 4. The horizontal adjustment component 6 is used to adjust the distance between the two cutting discs 5. Vertical adjustment components 7 are provided on both sides of the top of the mounting frame 1. The vertical adjustment components 7 are used to adjust the distance between the cutting discs 5 and the second conveyor roller 3. A tensioning component 8 is provided on one side of the mounting frame 1. The tensioning component 8 is used to adjust the tension of the belt.

[0021] The horizontal adjustment assembly 6 includes two mounting plates 61, which are disposed on both sides of the mounting frame 1. A slide rod 62 is rotatably connected between the two mounting plates 61. Threaded grooves 63 are provided on the outer sides of both ends of the slide rod 62. Moving plates 64 are threadedly connected to the outer sides of the threaded grooves 63. Rotating shafts 65 are rotatably connected to the moving plates 64. A rotating rod 4 moves through the two rotating shafts 65. A keyway 66 is provided inside the rotating shafts 65. A spline 67 is fixedly connected to the side of the rotating rod 4. The spline 67 is slidably engaged in the keyway 66.

[0022] By adopting the above technical solution, when it is necessary to adjust the cutting edge width on both sides of the film, the throttle 13 is turned to drive the slide rod 62 and the threaded groove 63 to rotate. The keyway 66 is used to limit the spline 67, so that the cutting disc 5 can rotate with the rotating rod 4, and the two rotating shafts 65 can be adjusted in distance along the outside of the rotating rod 4, thereby realizing the adjustment of the cutting edge width.

[0023] The vertical adjustment assembly 7 includes a movable groove 71, which is opened on both sides of the mounting frame 1. The mounting plate 61 is slidably engaged in the movable groove 71. Adjustment screws 72 are threadedly connected to both sides of the top of the mounting frame 1. The bottom end of the adjustment screw 72 is rotatably connected to the mounting plate 61.

[0024] By adopting the above technical solution, by rotating the adjusting screw 72, the mounting plate 61 is pushed to move vertically along the interior of the movable groove 71, thereby driving the cutting disc 5 to move vertically, realizing the adjustment of the distance between the bottom end of the cutting disc 5 and the conveying roller 3, which can adapt to the cutting of films of different thicknesses.

[0025] One end of the shaft of conveyor roller 2 extends to one side of the mounting frame 1 and is fixedly connected to synchronous belt 9. One end of the shaft of conveyor roller 2 extends to one side of the mounting frame 1 and is fixedly connected to synchronous belt 3 11. The outer sides of synchronous belt 9 and synchronous belt 3 11 are connected by belt drive. A stepper motor 12 is fixedly installed on the side of the mounting frame 1 away from synchronous belt 9. The drive end of the stepper motor 12 is fixedly connected to the shaft of conveyor roller 2.

[0026] By adopting the above technical solution, the stepper motor 12 drives the conveyor roller 2 and the synchronous belt 3 11 to rotate. The synchronous belt 3 11 is connected to the outer side of the synchronous belt 9 through belt drive, which simultaneously drives the conveyor roller 3 to rotate, thereby realizing the conveying of the film.

[0027] One end of the rotating rod 4 extends to one side of the mounting plate 61 and is fixedly connected to the second synchronous belt 10. One end of the shaft of the second conveyor roller 3 is fixedly connected to the side of the first synchronous belt 9, and the fourth synchronous belt 14 is connected to the outer side of the second synchronous belt 10 by belt drive.

[0028] By adopting the above technical solution, when the conveyor roller 2 3 rotates, it drives the synchronous belt 4 14 to rotate. The synchronous belt 4 14 is connected to the outer side of the synchronous belt 2 10 through belt drive, which simultaneously drives the rotating rod 4 and the cutting disc 5 to rotate, thereby realizing the cutting operation.

[0029] The tensioning assembly 8 includes a U-shaped frame 81, which is fixedly connected to the side of the mounting frame 1 near the timing belt 14. Limiting grooves 83 are provided on both sides of the inner wall of the U-shaped frame 81. A movable seat 82 is provided inside the U-shaped frame 81. Limiting blocks 84 are fixedly connected to both sides of the movable seat 82. The limiting blocks 84 are slidably engaged in the limiting grooves 83. A roller 86 is rotatably connected to the front end of the movable seat 82. The side of the roller 86 abuts against the belts connected to the timing belts 10 and 14. A bolt 85 is threadedly connected to one side of the U-shaped frame 81. One end of the bolt 85 is rotatably connected to the movable seat 82.

[0030] By adopting the above technical solution, when the mounting plate 61 moves vertically along the interior of the movable groove 71, it simultaneously drives the second synchronous belt 10 to move vertically, causing the tension of the belt between the second synchronous belt 10 and the fourth synchronous belt 14 to change. At this time, by rotating the bolt 85, the movable seat 82 and the roller 86 are pushed to one side of the belt, so that the roller 86 and the belt are in close contact, thereby ensuring the stable operation of the equipment. Furthermore, the cooperation between the limiting groove 83 and the limiting block 84 can limit the movement of the movable seat 82 and prevent the movable seat 82 from sliding out of the interior of the U-shaped frame 81.

[0031] The top of the adjusting screw 72 and one end of the slide rod 62 are both fixedly connected to the handle 13.

[0032] By adopting the above technical solution and setting the throttle 13, it is easier to rotate and adjust the adjusting screw 72 and the slide rod 62.

[0033] Working principle: When trimming the film, the stepper motor 12 drives the conveyor roller 2 and the synchronous belt 11 to rotate. The synchronous belt 11 is connected to the outer side of the synchronous belt 9 via belt drive, which in turn drives the conveyor roller 3 and the synchronous belt 14 to rotate, thus conveying the film. The synchronous belt 14 is connected to the outer side of the synchronous belt 10 via belt drive, which in turn drives the rotating rod 4 and the cutting disc 5 to rotate. This works in conjunction with the conveying device to achieve continuous trimming operation.

[0034] When it is necessary to adjust the cutting edge width of the film, the lever 13 connected to the slide rod 62 is rotated, which drives the slide rod 62 and the threaded groove 63 to rotate. The keyway 66 limits the spline 67, so that the cutting disc 5 can rotate with the rotating rod 4. At the same time, the two rotating shafts 65 can be adjusted along the outside of the rotating rod 4 to adjust the distance between them, thereby adjusting the cutting edge width. The mounting plate 61 can be pushed to move vertically along the inside of the movable groove 71 by rotating the adjusting screw 72, thereby driving the cutting disc 5 to move vertically and adjusting the distance between the bottom of the cutting disc 5 and the conveying roller 3. This can adapt to the cutting of films of different thicknesses.

[0035] When the mounting plate 61 moves vertically along the interior of the movable groove 71, it simultaneously drives the second synchronous belt 10 to move vertically, causing the tension of the belt between the second synchronous belt 10 and the fourth synchronous belt 14 to change. At this time, by rotating the bolt 85, the movable seat 82 and the roller 86 are pushed to one side of the belt, so that the roller 86 and the belt come into close contact, thereby ensuring the stable operation of the equipment.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
