[0024] In a preferred embodiment, the moving rod 12 is slidably connected to the moving groove 13. One end of the moving rod 12 is fixedly connected with a connecting rod 14. An extrusion plate 15 is fixedly connected to the outer wall of the connecting rod 14. When the moving rod 12 moves, the moving rod 12 can move inside the moving groove 13, and at the same time, the moving rod 12 will drive the connecting rod 14 to move.

[0025] In a preferred embodiment, the bottom end of the limiting sleeve 9 is fixedly connected with a movable plate 16. A movable groove 17 is opened at the bottom end of the movable plate 16. A movable block 18 is slidably connected inside the movable groove 17. The bottom end of the movable block 18 is fixedly connected with a rotating plate 19. When the movable block 18 moves, the movable block 18 will move inside the movable groove 17, and at the same time, the movable block 18 will drive the movable plate 16 to move.

[0026] In a preferred embodiment, the bottom end of the rotating plate 19 is fixedly connected with a driving shaft 20. The bottom end of the driving shaft 20 penetrates through the outer wall of the support plate 5 and the driving shaft 20 is rotatably connected to the support plate 5. The bottom end of the support plate 5 is fixedly connected with a motor 21. One end of the output shaft of the motor 21 is fixedly connected with the driving shaft 20. When the motor 21 of the support plate 5 is started, the output shaft of the motor 21 will drive the driving shaft 20 to move, so that the driving shaft 20 moves inside the first groove 6.

[0027] Working principle of the utility model: When using the device, place the large roll of raw material film with the roller on the top of the feeding plate 4. The top of the feeding plate 4 is inclined, so that the large roll of raw material film can roll on the top of the feeding plate 4. At the same time, the large roll of raw material film will drive the roller to cross the pressing plate 15. At this time, the lowest point of the bottom end of the large roll of raw material film will cross from the top of the feeding plate 4, causing the whole large roll of raw material film to sink. Furthermore, the large roll of raw material film will drive the roller to contact the arc surface at the top of the support plate 5. At this time, the outside of the roller contacts the arc surfaces at the tops of the pressing plate 15 and the support plate 5. Start the motor 21. The output shaft of the motor 21 drives the driving shaft 20 to move, so that the driving shaft 20 drives the rotating plate 19 to move, causing the rotating plate 19 to drive the movable block 18 to move, so that the movable block 18 slides in the movable groove 17. Furthermore, the rotating plate 19 drives the movable plate 16 to move in the first groove 6 through the movable block 18 and the movable groove 17. The movable plate 16 also drives the limit sleeve 9 to move, so that the limit sleeve 9 can slide on the outer wall of the limit rod 8. The limit sleeve 9 drives the sliding sleeve 10 to slide in the first groove 6. The sliding sleeve 10 also drives the sliding rod 11 to slide in the first groove 6. At the same time, the sliding rod 11 drives the moving rod 12 to move, so that the moving rod 12 slides in the moving groove 13. The moving rod 12 also drives the connecting rod 14 to move, so that the connecting rod 14 drives the pressing plate 15 to move. Furthermore, the pressing plate 15 can press the roller on the top of the support plate 5. The roller can reach one side of the engaging groove 22 from the arc surface at the top of the support plate 5. At this time, more than half of the roller located on the central axis has reached the top of the engaging groove 22. The roller enters the engaging groove 22 by relying on the weight of the large roll of raw material film. At this time, the raw material film in the subsequent large roll of raw material film passes through a plurality of conveying rollers 3 and reaches the film cutting device 2 for cutting. When all the raw material film on the outer wall of the roller is cut, start the cylinder 23 at this time. The output shaft of the cylinder 23 drives the pressing block 24 to move from the second groove 7 into the engaging groove 22, so that the inclined surface outside the pressing block 24 presses the roller. Furthermore, the roller can automatically move out of the engaging groove 22 and move to the top of the support plate 5, greatly improving the efficiency of loading and unloading the large roll of raw material film.

[0028] Please refer to Figure 1 and Figure 3 , the utility model provides a technical solution: An engaging groove 22 is formed in the top of the support plate 5 and the engaging groove 22 communicates with the second groove 7. A cylinder 23 is fixedly connected inside the second groove 7. The output end of the cylinder 23 is fixedly connected with a pressing block 24 and the pressing block 24 is slidably connected with the engaging groove 22. When the cylinder 23 is started, the output shaft of the cylinder 23 will move inside the second groove 7, and at the same time, the output shaft of the cylinder 23 will drive the pressing block 24 to move.

[0029] In a preferred embodiment, a regulating block 25 is fixedly connected to the bottom end of the support plate 5. A regulating groove 26 is formed in the bottom end of the regulating block 25. An adjusting bolt 27 is connected to the inside of the regulating groove 26 through a thread. The bottom end of the adjusting bolt 27 is rotatably connected to a support disc 28. When the adjusting bolt 27 moves, the adjusting bolt 27 will move inside the regulating groove 26, and at the same time, the adjusting bolt 27 can drive the support disc 28 to move.

[0030] The working principle of the present utility model: When the installation ground is uneven and independent fine adjustment is required for multiple support discs 28 at the bottom end of the support plate 5, at this time, the adjusting bolt 27 is rotated to make the adjusting bolt 27 move inside the adjusting groove 26 inside the regulating block 25, so that the adjusting bolt 27 and the adjusting groove 26 move through the thread, and then the threaded rod can move up and down inside the adjusting groove 26, so that the distance between the subsequent support disc 28 and the support plate 5 is convenient to adjust, and further the distance between the support disc 28 and the support plate 5 can be adaptively adjusted according to the ground.
