[0028] By setting up a slitting assembly, plastic films of different sizes can be processed. The slitting assembly includes a fixed plate 2, a first slide rail 3, and a slide block 4. A third slide rail 29 is fixedly connected to the top of one inner end of the fixed frame 1. The fixed plate 2 is slidably connected to the third slide rail 29. A fourth electric push rod 30 is installed on one inner end of the fixed frame 1. One end of the fourth electric push rod 30 is installed on the fixed plate 2. The push rod of the fourth electric push rod 30 drives the fixed plate 2 to move on the third slide rail 29, so that the blade 6 slits the plastic film. The first slide rail 3 is fixedly connected to the top of the fixed plate 2, and the slide block 4 slides. Connected to the top of the first slide rail 3, one end of the slide block 4 has a mounting post 5 that can be movably passed through it. A blade 6 is installed at one end of the mounting post 5. The top of the slide block 4 is connected to a first fixing bolt 7 and a second fixing bolt 8 by threads. When the position of the blade 6 needs to be adjusted, the second fixing bolt 8 is rotated in the opposite direction, and one end of the second fixing bolt 8 is disengaged from the top of the first slide rail 3. At this time, the position of the mounting post 5 can be moved to complete the position adjustment of the blade 6. Then, the second fixing bolt 8 is rotated in the forward direction, and one end of the second fixing bolt 8 abuts against the top of the mounting post 5 to complete the fixing of the mounting post 5.

[0029] One end of the first fixing bolt 7 passes through the slide block 4 and abuts against the top of the fixing plate 2, and one end of the second fixing bolt 8 is inserted into the interior of the slide block 4 and abuts against the top of the first slide rail 3. By rotating the first fixing bolt 7, one end of the first fixing bolt 7 is disengaged from the top of the fixing plate 2. At this time, the position of the slide block 4 on the first slide rail 3 can be moved according to the processing requirements of the plastic film, thereby adjusting the position of the blade 6. Then, the position of the slide block 4 is fixed by rotating the first fixing bolt 7.

[0030] By setting up a feeding assembly, the feeding of plastic film can be completed quickly. The feeding assembly includes a take-up roller 9, a first reduction motor 10, and a second slide rail 11. One end of the take-up roller 9 is rotatably connected to one end of the fixed frame 1. The first reduction motor 10 is installed on one side of one end of the fixed frame 1, and the output shaft of the first reduction motor 10 is fixedly connected to one end of the take-up roller 9. The second slide rail 11 is fixedly connected to the other side of one end of the fixed frame 1. One end of an L-shaped slide 12 is slidably connected to the second slide rail 11. The other end of the L-shaped slide 12 has a placement groove 13, which is located behind the other end of the take-up roller 9. A [missing information - likely a device or component] is installed on the other side of one end of the fixed frame 1. The first electric push rod 14 has its push rod end fixedly connected to one side of the L-shaped carriage 12. Before processing, the push rod of the first electric push rod 14 drives the L-shaped carriage 12 to move on the second slide rail 11, so that the take-up roller 9 is located inside the placement groove 13, which can support the other end of the take-up roller 9. After processing, the push rod of the first electric push rod 14 drives the L-shaped carriage 12 to reset, and one end of the take-up roller 9 is disengaged from the placement groove 13, so that the cut plastic film can be easily removed. During winding, the first reduction motor 10 drives the take-up roller 9 to rotate, so that the take-up roller 9 completes the winding of the plastic film.

[0031] To improve the processing efficiency of plastic film, the feeding assembly includes two first arms 16 and two connecting columns 17. A first rotating shaft 15 and a second rotating shaft 19 are rotatably connected to the other end of the inner side of the fixing frame 1. The two first arms 16 are fixedly sleeved on the outer ends of the first rotating shaft 15 and located inside the fixing frame 1. The two connecting columns 17 are fixedly connected to both ends of the first rotating shaft 15. A second electric push rod 18 is installed on the other end of each side of the fixing frame 1. The push rod end of the second electric push rod 18 is hinged to one end of the connecting column 17. A second arm 20 is installed on the outer ends of the second rotating shaft 19, located inside the fixing frame 1. A third electric push rod 21 is installed on both inner sides of the fixing frame 1. One end of the third electric push rod 21 is hinged to the second arm 16. On arm 20; the push rod of the second electric push rod 18 pushes one end of the connecting column 17 to move, the connecting column 17 drives the first support arm 16 on the first rotating shaft 15 to rotate, so that the first support arm 16 moves downward, and then moves both ends of the expansion roller into the groove of the first support arm 16. The first support arm 16 drives the material on the expansion roller to move to the top of the fixed frame 1. During the movement of the first support arm 16, the third electric push rod 21 pushes the second rotating shaft 19 on the second support arm 20 to rotate, and the second support arm 20 moves to the bottom of the expansion roller. Then the third electric push rod 21 drives the second support arm 20 to reset, so that the groove at the top of the second support arm 20 moves to the outside of the expansion roller, and the material on the expansion roller can be moved and fed through the second support arm 20.

[0032] The material guiding assembly includes a first rotating roller 22, a first gear disk 23, a first guide roller 24, a second guide roller 25, and a second rotating roller 26. All three components are mounted inside the fixed frame 1. During plastic film processing, one side of the plastic film on the expansion roller is wrapped around the outside of the first rotating roller 22, the first guide roller 24, the second guide roller 25, and the second rotating roller 26, and then the plastic film is wound up by the take-up roller 9. The first gear disk 23 is fixedly sleeved at both ends of the outer side of the first rotating roller 22 inside the fixed frame 1, and the second rotating roller... The outer ends of the second roller 26 are fixedly sleeved with the second gear disk 27 on the inner side of the fixed frame 1. The first gear disk 23 and the second gear disk 27 are connected by a chain. A second reduction motor 28 is installed on one side of the fixed frame 1. The output shaft of the second reduction motor 28 is fixedly connected to one end of the second roller 26 extending to the outer side of the fixed frame 1. During slitting, the output shaft of the second reduction motor 28 drives the second roller 26 to rotate. The second roller 26 drives the first gear disk 23 to rotate through the second gear disk 27, thereby driving the first roller 22 to rotate. At this time, the plastic film can be transported by the first roller 22 and the second roller 26.

[0033] The working principle or structural principle is as follows: When processing plastic film, one side of the plastic film on the expansion roller is wrapped around the outside of the first rotating roller 22, the first guide roller 24, the second guide roller 25, and the second rotating roller 26. Then, the plastic film is wound up by the take-up roller 9. Before slitting, the first fixing bolt 7 is rotated so that one end of the first fixing bolt 7 is disengaged from the top of the fixing plate 2. At this time, the position of the slide 4 on the first slide rail 3 can be moved according to the processing requirements of the plastic film, thereby adjusting the position of the blade 6. Then, the position of the slide 4 is fixed by rotating the first fixing bolt 7. During slitting, the first reduction motor 10 and the second reduction motor 28 are started by the switch group. The output shaft of the second reduction motor 28 drives the second rotating roller 26 to rotate. The second rotating roller 26 drives the first gear disk 23 to rotate through the second gear disk 27, thereby driving the first rotating roller 22 to rotate. At this time, the plastic film can be transported by the first rotating roller 22 and the second rotating roller 26.

[0034] Then, the push rod of the fourth electric push rod 30 is extended by the switch group. The push rod of the fourth electric push rod 30 drives the fixed plate 2 to move on the third slide rail 29, so that the blade 6 cuts the plastic film. At the same time, the cut plastic film will drive the take-up roller 9 to rotate through the first reduction motor 10, so that the take-up roller 9 completes the take-up of the plastic film. Before processing, the push rod of the first electric push rod 14 needs to be extended by the switch group. The push rod of the first electric push rod 14 drives the L-shaped carriage 12 to move on the second slide rail 11, so that the take-up roller 9 is located inside the placement groove 13, which can support the other end of the take-up roller 9. After processing, the push rod of the first electric push rod 14 drives the L-shaped carriage 12 to reset, and one end of the take-up roller 9 is removed from the inside of the placement groove 13, so that the cut plastic film can be easily removed.

[0035] When it is necessary to feed plastic film, the push rod of the second electric push rod 18 is extended by controlling the switch group. The push rod of the second electric push rod 18 pushes one end of the connecting column 17 to move. The connecting column 17 drives the first support arm 16 on the first rotating shaft 15 to rotate, so that the first support arm 16 moves downward. Then, the two ends of the expansion roller are moved into the groove of the first support arm 16. The first support arm 16 drives the material on the expansion roller to the top of the fixed frame 1. During the movement of the first support arm 16, the second rotating shaft 19 on the second support arm 20 is pushed to rotate by the third electric push rod 21. The second support arm 20 then moves to the bottom of the expansion roller. Then, the third electric push rod 21 drives the second support arm 20 to reset, so that the groove at the top of the second support arm 20 moves to the outside of the expansion roller. The material on the expansion roller can be moved and fed by the second support arm 20.
