Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Specific embodiments are given below.

[0026] Please refer to Figure 1 - Figure 5 , the present utility model provides a food packaging material winding device, including a base 1. Both ends of the base 1 are provided with opening grooves 2, and a positioning block 3 is sleeved inside each opening groove 2. A threaded rod 4 is threadedly connected to the bottom inner wall of each positioning block 3, and both ends of each threaded rod 4 are rotatably connected to the inner walls of both ends of the opening groove 2. Fixedly connected to the inner walls of both ends of the base 1 are first motors 5, and one end of the output shaft of each first motor 5 is fixedly connected to one end of the threaded rod 4. Sliding grooves 6 are provided on both sides of the bottom of each positioning block 3, and a sliding plate 7 is slidably connected to the inner wall of each sliding groove 6. One side of each pair of sliding plates 7 is fixedly connected to the inner wall of the opening groove 2, and both sides of each positioning block 3 are in contact with the inner wall of the opening groove 2 through the sliding plate 7. Rotatably connected to the top inner wall of each positioning block 3 is a bearing 8, fixedly connected to the inner wall of each bearing 8 is a transmission rod 9, fixedly connected to the middle of each transmission rod 9 is a positioning collar 10, and a winding drum 11 is rotatably connected between the two transmission rods 9. Both ends of the winding drum 11 are in contact with one side of the positioning collar 10 through the transmission rod 9. Fixedly connected to one side of a positioning block 3 is a positioning plate 12, and fixedly connected to one side of the positioning plate 12 is a second motor 13. One end of the output shaft of the second motor 13 is fixedly connected to one end of a transmission rod 9.

[0027] During operation, by installing the base 1 at the tail of the device, when it is necessary to wind up the packaging bag material, the reel 11 is placed between the two transmission rods 9, and then the first motor 5 is started. The output shaft of the first motor 5 drives the threaded rod 4 to rotate. By using the connection between the outer wall of the threaded rod 4 and the inner wall of the positioning block 3, the two positioning blocks 3 can slide inside the opening groove 2 simultaneously, so that one end of the two transmission rods 9 can be inserted into the reel 11 at the same time. After both ends of the reel 11 are in contact with one side of the positioning collar 10, the first motor 5 stops rotating. The two positioning blocks 3 are positioned inside the opening groove 2. By using the connection between the chute 6 and the outer wall of the slide plate 7, it can prevent the positioning block 3 from being misaligned during movement, ensuring the stability of the structure and preventing the transmission rod 9 from being misaligned when inserted into both ends of the reel 11. Then, one end of the packaging material is pasted on the outer wall of the reel 11. The positioning plate 12 ensures the stability of the second motor 13, and then the second motor 13 is started. The output shaft of the second motor 13 drives one of the transmission rods 9 to rotate, and then the reel 11 can be driven to rotate, so as to wind up the material. The bearing 8 enables the transmission rod 9 to rotate stably inside the positioning block 3, reducing the friction between the structures and preventing the transmission rod 9 from jamming during rotation, which can improve the winding efficiency of the packaging material. By adopting the above method, when the size of the packaging material changes, it can meet the installation requirements of reels with different widths or sizes, improve the installation efficiency of the reels, and improve the practicability and working efficiency of the device.

[0028] Further, as Figure 2 and Figure 3 shown, an activity groove 18 is provided on the inner wall of one end of each transmission rod 9. One end of the activity groove 18 is fixedly connected with a third motor 19, and one end of the output shaft of the third motor 19 is fixedly connected with a connecting rod 20. The other end of the connecting rod 20 is rotatably connected with the inner wall of one end of the transmission rod 9. The middle of the connecting rod 20 is fixedly connected with a diamond-shaped rod 21, and the diamond-shaped rod 21 is rotatably connected with the inner wall of the activity groove 18 through the connecting rod 20.

[0029] During operation, by starting the third motor 19, the output shaft of the third motor 19 drives the connecting rod 20 to rotate inside the activity groove 18. By using the fixed connection between the connecting rod 20 and the diamond-shaped rod 21, the rotation of the connecting rod 20 can drive the diamond-shaped rod 21 to rotate inside the activity groove 18, which can reduce the friction between the outer wall of the diamond-shaped rod 21 and the inner wall of the activity groove 18, and is convenient for the staff to operate, and can improve the service life of the device.

[0030] Further, as Figure 4As shown in the figure, a plurality of limiting grooves 14 are formed in the outer wall of one end of each transmission rod 9. One end of each limiting groove 14 communicates with one end of the movable groove 18. The inner wall of each limiting groove 14 is slidably connected with a limiting block 15. One side of each limiting block 15 is attached to the outer wall of the diamond-shaped rod 21. The plurality of limiting blocks 15 all slide inside the limiting grooves 14 via the diamond-shaped rod 21. Rectangular grooves 17 are formed on both sides of each limiting groove 14. A rectangular block 16 is sleeved inside each rectangular groove 17. One side of each rectangular block 16 is fixedly connected to one side of the limiting block 15. Each rectangular block 16 slidably connects with the inner wall of the rectangular groove 17 via the limiting block 15.

[0031] During operation, after installing the drum 11 on the outer wall of one end of the two transmission rods 9, by rotating the diamond-shaped rod 21, the corners of the diamond-shaped rod 21 can push the limiting block 15 to slide inside the limiting groove 14. Furthermore, it can drive the rectangular block 16 to slide on the inner wall of the rectangular groove 17, preventing the limiting block 15 from falling off and improving the structural stability. And as the plurality of limiting blocks 15 move, one side of the plurality of limiting blocks 15 is attached to the inner wall of the drum 11. The mutual cooperation of the plurality of limiting blocks 15 can fix the drum 11 on the outside of the transmission rod 9, enabling the drum 11 to rotate synchronously with the transmission rod 9, preventing the situation that the transmission rod 9 and the drum 11 have different rotation speeds during rotation, and improving the use efficiency and winding effect of the device.

[0032] Working principle: By installing the base 1 at the tail of the device, when it is necessary to wind the packaging bag material, place the drum 11 between the two transmission rods 9, then start the first motor 5. The output shaft of the first motor 5 drives the threaded rod 4 to rotate. Due to the connection between the outer wall of the threaded rod 4 and the inner wall of the positioning block 3, the two positioning blocks 3 slide inside the opening groove 2 at the same time, making the sliding groove 6 slide on the outer wall of the sliding plate 7, so that one end of the two transmission rods 9 can be inserted into the drum 11 at the same time, and then the first motor 5 stops rotating. By starting the third motor 19, the output shaft of the third motor 19 drives the connecting rod 20 to rotate inside the movable groove 18. The rotation of the connecting rod 20 can drive the diamond-shaped rod 21 to rotate inside the movable groove 18. The corners of the diamond-shaped rod 21 can push the limiting block 15 to slide inside the limiting groove 14, and then drive the rectangular block 16 to slide on the inner wall of the rectangular groove 17. The mutual cooperation of the plurality of limiting blocks 15 can fix the drum 11 on the outside of the transmission rod 9. Then stick one end of the packaging material to the outer wall of the drum 11, and then start the second motor 13. The output shaft of the second motor 13 drives one transmission rod 9 to rotate, and then can drive the drum 11 to rotate, so as to wind the material.
