Technical Field

[0001] The utility model relates to the technical field of efficient winding of PET films, and particularly relates to an efficient winding device for PET film production. Background Technique

[0002] The PET film is also known as a high-temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in the fields of magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging and decoration, screen protection, optical-grade mirror surface protection, etc.

[0003] In the prior art, after the PET film is produced, it needs to be wound to facilitate storage or transportation operations. However, the traditional winding operation is relatively simple. When the PET film is wound, the edges are not clamped and resisted, resulting in a twisting problem. Therefore, after winding, it is not evenly spread out for winding, so it needs to be reversed and rotated to flatten it and then wound again. Therefore, the winding efficiency has not been improved, and the operation is inconvenient. Summary of the Utility Model

[0023] See also Figures 1-4, the present utility model provides a technical solution: an efficient winding device for PET film production, which includes: a fixed bottom plate 1, a winding roller 3 is arranged at one end above the fixed bottom plate 1. The PET film 6 passes through the winding baffle 5 through the opening 8, and then extends out through the edge of the groove plate 4 to complete the winding operation with the winding roller 3. Both ends of the winding roller 3 are rotatably matched with side plates 16. One side plate 16 is fixedly connected to the fixed bottom plate 1, and the other side plate 16 is movably connected to the fixed bottom plate 1. Groove plates 4 are arranged on both sides of the middle above the fixed bottom plate 1. Through the concave groove 9 structure inside the groove plate 4, the edge of the PET film 6 can be resisted to complete the stable winding operation and prevent the torsion problem. The groove plates 4 move closer to and away from the middle to facilitate the clamping and resistance of PET films 6 with different widths. A concave groove 9 is opened inside the groove plate 4. Rotating frames are fixedly connected to the upper and lower sides of the front end of the concave groove 9. Auxiliary rollers 10 are rotatably matched inside the rotating frames. Arc-shaped resisting openings 11 are fixedly connected to the upper and lower ends outside the concave groove 9. A winding baffle 5 is fixedly connected to the other end above the fixed bottom plate 1. An installation plate 14 is fixedly connected to the outside of one side plate 16. A driving motor 2 is fixedly connected to the upper part of the installation plate 14. The driving motor 2 drives the plug block 13 to be inserted and matched with the support tube 12 to complete the winding of the winding roller 3 and complete the winding function of the PET film 6. The driving end of the driving motor 2 is fixedly connected to the plug block 13.

After the bidirectional screw 7 rotates, through the bidirectional opposite thread setting, the threaded blocks can be adjusted to move closer to or away from the middle, and the groove plate 4 can be adjusted to move closer to and away from the middle, which is convenient for clamping and resisting PET films 6 with different widths. Subsequently, the driving motor 2 drives the plug block 13 to be inserted and matched with the support tube 12 to complete the winding of the winding roller 3 and complete the winding function of the PET film 6. When the winding roller 3 needs to be disassembled after winding, the bolt 15 can be rotated. After rotation, the side plate 16 is disassembled, and then the winding roller 3 can be slid towards the disassembly end, and the convex block and chute structure between the plug block 13 and the support tube 12 can be slid and separated to complete the disassembly.
