[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-6This utility model provides an embodiment of a casting film winding device, comprising a bottom support 1, vertical supports 2, and long vertical supports 3. Long vertical supports 3 are welded and fixed to the rear upper ends of the bottom supports 1 on both sides. Two vertical supports 2 are welded and fixed to the upper ends of the bottom supports 1 on both sides, located in front of the long vertical supports 3. A rotating shaft 4 is provided at the upper end between the two long vertical supports 3 and the two vertical supports 2 on each side. The rotating shaft 4 rotates on the long vertical supports 3 and the vertical supports 2, rolling during the conveying of the casting film mold for better conveying. A large roller 14 is provided along the outer side of the rotating shaft 4 between the two long vertical supports 3. A large roller groove 18 is opened on the outer end face of the large roller 14. Two component rotating shafts 21 are arranged inside the large roller groove 18. Component rollers 20 are arranged outside the two component rotating shafts 21. Both sides of the component rotating shafts 21 are... A rotating gear 19 is provided. A support column 25 is fixed on one side inside the large roller groove 18. Multiple springs 24 are arrayed and connected to the lower end of the support column 25 along the component rotation axis 21. The other ends of the multiple springs 24 are connected to a movable limiting plate 23. Multiple movable guide rails 22 are arrayed and arranged inside the large roller groove 18 along the component rotation axis 21. The movable limiting plate 23 is slidably connected to the large roller groove 18 through the movable guide rails 22. The movable guide rails 22 are located on one side of the two rotating gears 19. The rotation of the rotating gear 19 controls the rotation of the component rotation axis 21. The component rotation axis 21 drives the component roller 20 to rotate, and the cast film is transferred and fixed inside the two component rollers 20. When the rotating gear 19 rotates, the movable limiting plate 23 moves downward along the movable guide rail 22 until the movable limiting plate 23 presses the springs 24 downward. Then, the large roller 14 rotates to wind up the cast film.

[0024] Furthermore, a fixing plate 10 is provided at the upper end of the bottom bracket 1 along the upper and lower ends between the two vertical brackets 2, and a limit post 11 is provided at the four corners between the upper and lower fixing plates 10. A vertical moving motor 12 is provided at the upper end of the lower fixing plate 10, and a threaded post 13 is connected to the output shaft end of the vertical moving motor 12. The vertical moving motor 12 drives the threaded post 13 to rotate.

[0025] Furthermore, rotating gears 15 are provided at the upper and lower ends of the outer side of the long vertical support 3 on one side. The two rotating gears 15 are rotatably connected by a transmission belt 16. The upper rotating gear 15 is connected to the large roller 14 through the rotating shaft 4 between the two long vertical supports 3. A rotary motor 17 is installed at the rear end of the outer side of the bottom support 1, and the lower rotating gear 15 is connected to the output shaft of the rotary motor 17. The rotary motor 17 drives the lower rotating gear 15 to rotate. The lower rotating gear 15 drives the upper rotating gear 15 to rotate through the transmission belt 16. The upper rotating gear 15 rotates coaxially with the rotating shaft 4 between the two long vertical supports 3. The rotating shaft 4 rotates coaxially with the large roller 14. The large roller 14 is rotated by the rotary motor 17 to perform the winding operation.

[0026] Furthermore, the upper moving shaft 6 and the lower moving shaft 7 are connected through the threaded columns 13 on both sides. The upper moving shaft 6 is located above the lower moving shaft 7. The upper moving shaft 6 has an upper rotating groove 8 along the threaded column 13, and the lower moving shaft 7 has a lower rotating groove 9 along the two threaded columns 13 on both sides. The upper rotating groove 8 and the lower rotating groove 9 have opposite thread directions. The up and down moving motor 12 drives the threaded column 13 to rotate. Because the upper rotating groove 8 and the lower rotating groove 9 at both ends of the upper moving shaft 6 and the lower moving shaft 7 can move closer to or further away from the center at the same time, the height of the cast film that can be output from the roller 5 outside the upper moving shaft 6 and the lower moving shaft 7 is limited.

[0027] Furthermore, rollers 5 are provided on the outside of the rotating shaft 4, the upper moving shaft 6, and the lower moving shaft 7 between the two vertical supports 2, so that the casting film can be transported better by rotating the rollers 5.

[0028] Furthermore, a film support frame 26 is connected between the two rear vertical supports 2. The film support frame 26 is located at the lower end of the rotating shaft 4 between the two rear vertical supports 2. After the cast film is transported to the film support frame 26, it continues to be transported to the large roller 14. This not only supports the cast film but also facilitates better transport.

[0029] Furthermore, movable tubes 27 are provided at both ends of the rotating shaft 4 between the two long vertical supports 3. After the casting film winding operation is completed, the rotating shaft 4 between the long vertical supports 3 can be disassembled through the movable tubes 27 to remove the wound casting film from the outside of the large roller 14 for better stacking and to continue the next step of the task.

[0030] Working principle: The cast film is fed in from the front and fixed to the film support frame 26. The rollers 5 at the outer ends of the rotating shafts 4 between the two vertical supports 2 restrict and fix the cast film. During the output process, the cast film passes between the upper moving shaft 6 and the lower moving shaft 7 and the outer rollers 5. The up and down moving motors 12 on both sides drive the threaded columns 13 to rotate. When the two threaded columns 13 rotate, the upper rotating grooves 8 and the lower rotating grooves 9 at both ends of the upper moving shaft 6 and the lower moving shaft 7 have opposite thread directions. At the same time, the upper moving shaft 6 and the lower moving shaft 7 are controlled to move towards the center or the edge. After the cast film is transported to the rollers 5 at the outer ends of the rotating shafts 4 between the rear vertical supports 2, the film support frame 26 initially guides the cast film to be output to the large roller 14. The rotation in the groove 18 of the large roller... Gear 19 rotates and clamps the front end of the cast film from the two component rollers 20 towards the center to fix the cast film. The rotary motor 17 drives the lower rotating gear 15 to rotate. The lower rotating gear 15 is driven to rotate through the transmission belt 16. The rotating gear 15 rotates coaxially with the rotating shaft 4 between the long vertical support 3. The rotating shaft 4 between the long vertical support 3 drives the large roller 14 to rotate, thus performing the casting film winding operation. After the casting film is wound up, the spring 24 rebounds and controls the movement limiting plate 23 to rotate the rotating gear 19 in the opposite direction, releasing the front end of the cast film from inside the two component rollers 20. The movable tube 27 moves to disassemble the rotating shaft 4 between the long vertical support 3 and collect the wound casting film.
