[0031] Embodiment 2: Reference Figure 4-Figure 7 , which is basically the same as the first embodiment, and further discloses a specific implementation scheme of the clamping part.

[0032] The above-mentioned clamping part includes a short shaft 7 rotatably connected to both sides of the reel 5, and the opposite surfaces of the two short shafts 7 are provided with sliding holes 9, and sliding rods 10 are slidably installed in the two sliding holes 9. The axial end surface shape of the sliding rod 10 and the sliding hole 9 can be hexagonal, and a return spring 11 is installed between the sliding rod 10 and the inner wall of the sliding hole 9. Among them, both ends of the reel 5 are provided with positioning holes 8 cooperating with the sliding rod 10, and the positioning holes 8 and the sliding rod 10 are fixedly connected with mutually attractive magnets 12, and the shape of the magnet 12 is long strip-shaped. A first motor 15 is fixedly installed on the bracket 1, and the output shaft of the first motor 15 is connected to one of the short shafts 7 through a first worm gear 16.

[0033] When the slide bar 10 is aligned with the positioning hole 8 of the reel 5, the magnet 12 on the slide bar 10 will be attracted by the magnet 12 in the positioning hole 8, and the slide bar 10 will be inserted into the positioning hole 8, so that the reel 5 can be fixed on the two short shafts 7. When in use, starting the first motor 15 can drive the short shaft 7 to rotate through the first worm gear 16, and the short shaft 7 will drive the reel 5 to rotate through the slide bar 10, and the reel 5 can wind the film around the outer wall.

[0034] Embodiment three: Reference Figure 4-Figure 5 as well as Figure 9-11 , which is basically the same as the second embodiment, and further discloses a specific implementation scheme of the switching unit.

[0035] The above-mentioned switching part includes a second motor 21 fixedly mounted on the bracket 1, and a driving shaft 22 is rotatably connected to the bracket 1, wherein the driving shaft 22 is connected to the rotating shaft 3 via a second worm gear 23, an incomplete gear 24 is fixedly mounted on the output shaft of the second motor 21, and the gear teeth of the incomplete gear 24 are only half, and a driven gear 25 meshingly connected with the incomplete gear 24 is fixedly mounted on the driving shaft 22.

[0036] When the winding reaches a preset thickness, the second motor 21 is started, so that the second motor 21 drives the incomplete gear 24 to rotate one circle. The incomplete gear 24 drives the driving shaft 22 to rotate through the driven gear 25 in the first half circle. The driving shaft 22 drives the rotating shaft 3 to rotate through the second worm gear 23. The rotating shaft 3 drives the drum 4 to rotate counterclockwise at a fixed angle, so that multiple reels 5 can be exchanged at the same time to complete the roll changing work.

[0037] The above-mentioned slide rod 10 is fixedly connected with a pull rod 13 that passes through the short shaft 7, and the end of the pull rod 13 is fixedly connected with a push plate 14. The bottom of the bracket 1 is fixedly connected with a trapezoidal block 38. When the push plate 14 moves to the bottom of the bracket 1 following the reel 5, the trapezoidal block 38 will press the push plate 14 in the direction away from the slide rod 10.

[0038] Specifically, when the reel 5 moves to the lower end of the bracket 1, the trapezoidal block 38 will press the push plates 14 on both sides, and the two push plates 14 will pull the slide bar 10 out of the positioning hole 8 through the pull rod 13. The wound reel 5 is no longer positioned by the two slide bars 10 and falls from the drum 4, thereby automatically completing the automatic unloading of the reel 5 and further improving the production efficiency of the pipeline.

[0039] A material guide tube 36 is fixedly connected to the top of the bracket 1 , and the position of the material guide tube 36 corresponds to the position of the trapezoidal block 38 . When the reel 5 falls downward, the reel 5 can slide downward along the inner wall of the material guide tube 36 .

[0040] Embodiment 4: Reference Figure 4 and Fig. 9 , which is basically the same as Example 3, and further discloses a specific implementation scheme of the reciprocating part.

[0041] The above-mentioned reciprocating part includes a reciprocating screw 27 rotatably connected to the bracket 1, a slide 28 is threadedly connected to the reciprocating screw 27, a delivery pipe 26 is fixedly connected to the slide 28, and a passive gear 29 is fixedly installed on the reciprocating screw 27. When the incomplete gear 24 is not engaged with the driven gear 25, the incomplete gear 24 will engage with the passive gear 29.

[0042] Specifically, when the incomplete gear 24 is not meshed with the driven gear 25, the second half circle of the incomplete gear 24 will mesh with the passive gear 29, and the passive gear 29 will drive the reciprocating screw 27 to rotate, and the reciprocating screw 27 will drive the conveying pipe 26 to reciprocate once through the slide 28. When the conveying pipe 26 moves toward the drum 4, a reel 5 in the output end of the conveying pipe 26 will be aligned with one of the pairs of slide bars 10. At this time, the magnet 12 on the slide bar 10 will be attracted by the magnet 12 in the positioning hole 8, and the slide bar 10 will be inserted into the positioning hole 8. When the conveying pipe 26 moves in the direction of reset, the reel 5 at its output end will be limited by the two slide bars 10, and the loading work of the reel 5 can be automatically completed, further improving the production efficiency of the pipeline. Since the magnet 12 is in the shape of a long strip, when the two magnets 12 attract each other, the reel 5 will be automatically rotated so that the two magnets 12 are completely aligned, and then the slide bar 10 is aligned with the positioning hole 8.

[0043] A winding method for producing a cast film roll core tube, the operating steps are as follows: Step 1: The reel 5 with the film fixed on the outer wall is continuously rotated; Step 2: After the current reel 5 is wound, the reel 5 at the adjacent position is replaced to replace the current reel 5; Step 3: clamp the film into the clamping slot 6 of the reel 5 and cut the film; Step 4: The wound roll 5 is automatically separated from the drum 4; Step 5: Make the empty roll 5 stuck on the roller 4; Step 6: Repeat steps 1 to 5 above.

[0044] The winding equipment for producing cast film roll core tubes is used. When the first motor 15 is started, the short shaft 7 can be driven to rotate through the first worm gear 16, and the short shaft 7 will drive the reel 5 to rotate through the slide bar 10, so that the reel 5 can wind the film onto the outer wall. When it is wound to a preset thickness, the second motor 21 is started, so that the second motor 21 drives the incomplete gear 24 to rotate one circle. The incomplete gear 24 will drive the driving shaft 22 to rotate through the driven gear 25 in the first half circle, and the driving shaft 22 will drive the rotating shaft 3 to rotate through the second worm gear 23. The rotating shaft 3 will drive the drum 4 to rotate counterclockwise at a fixed angle, so that multiple reels 5 can be exchanged at the same time. Since the film is not cut, the film wound on the reel 5 will be placed on another adjacent reel 5. At this time, the telescopic device 17 drives the insert plate 19 to reciprocate once, and the insert plate 19 will clamp the film into the clamping slot 6 of the reel 5, thereby automatically completing the reel change and fixation of the reel 5, indirectly improving the production efficiency of the pipeline.

[0045] When the insert plate 19 is fully inserted into the card slot 6, the arc plate 18 moving synchronously with the insert plate 19 will drive the blade 20 to fit the outer wall of the reel 5 and automatically cut the film, thereby automatically completing the reeling work, significantly improving the degree of automation, and further improving the production efficiency of the pipeline. At this time, the original reel 5 is rotated again to allow the cut film to be completely wound around the reel 5.

[0046] When the incomplete gear 24 is not meshed with the driven gear 25, the second half circle of the incomplete gear 24 will mesh with the driven gear 29, and the driven gear 29 will drive the reciprocating screw 27 to rotate, and the reciprocating screw 27 will drive the conveying pipe 26 to reciprocate once through the slide 28. When the conveying pipe 26 moves toward the drum 4, a reel 5 in the output end of the conveying pipe 26 will be aligned with one of the pairs of slide bars 10. At this time, the magnet 12 on the slide bar 10 will be attracted by the magnet 12 in the positioning hole 8, and the slide bar 10 will be inserted into the positioning hole 8. When the conveying pipe 26 moves in the direction of reset, the reel 5 at its output end will be limited by the two slide bars 10, and the loading work of the reel 5 can be automatically completed, further improving the production efficiency of the pipeline. Since the magnet 12 is in the shape of a long strip, when the two magnets 12 attract each other, the reel 5 will be automatically rotated so that the two magnets 12 are completely aligned, and then the slide bar 10 is aligned with the positioning hole 8.

[0047] When the reel 5 moves to the lower end of the bracket 1, the trapezoidal block 38 will press the push plates 14 on both sides, and the two push plates 14 will pull the slide bar 10 out of the positioning hole 8 through the pull rod 13. The wound reel 5 is no longer positioned by the two slide bars 10 and falls from the drum 4, thereby automatically completing the automatic unloading of the reel 5 and further improving the production efficiency of the pipeline. When the push plate 14 passes over the trapezoidal block 38, the return spring 11 will pull the slide bar 10 to return to the slide hole 9.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
