Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of winding equipment, specifically referring to a winding and stacking device for PET sheets. Background Technology
[0002] PET sheet winding is one of the important steps in PET sheet production. Its main function is to roll the PET sheets into rolls or strips after they have been processed by cutting and trimming, so that they can be transported and stored.
[0003] Traditional take-up rollers have a fixed width and cannot adapt to PET sheets of different widths. If a wider take-up roller is used directly, although it can meet the size requirements, it is easy to cause lateral deviation during high-speed winding, resulting in uneven edges of the roll. Therefore, the take-up roller needs to be disassembled and replaced with a suitable size according to the size of the PET sheet. This requires frequent equipment changes and is inefficient. In addition, there is no integrated drying device before the sheet is wound up. Residual solvents or moisture can easily cause the roll to stick together or become moldy, affecting the quality of the finished product. If the wound sheets are stacked directly, they are easy to be scratched by manual handling. Utility Model Content

The material guiding and drying device 2 includes a material guiding plate 21 and a fan 22 located at the bottom of the lower plate 12. A drying hole 101 is opened on the side of the lower plate 12 near the opening of the stacking rack 1. The material guiding plate 21 is arranged in an inverted U-shape and fits against one side of the drying hole 101. A guide hole 201 is opened at the bottom of the material guiding plate 21. PET sheets pass over the drying hole 101 and through the guide hole 201. The fan 22 exhausts air upward through the drying hole 101. A guide block 202 is provided on the side of the material guiding plate 21 near the drying hole 101.
[0039] Further explanation: the material guiding and drying device 2 also includes a heating box 23. The air outlet of the fan 22 is connected to the side of the heating box 23.

[0040] In this structure, hot air is evenly distributed over the surface of the sheet through the drying hole 101 to dry the PET sheet, reduce roll adhesion, and facilitate improved winding quality.
[0041] Example 2
[0042] To reduce offset during the winding process and further improve winding quality, refer to Figures 1-3 As shown, it also includes an adjustable winding device 3 installed on the stacking rack 1.
