Description

Ultrathin film reel

Technical Field

The utility model relates to an ultra-thin film production technical field especially relates to an ultra-thin film reel.

Background

The ultrathin film (the thickness of which is generally less than 10 microns) material can realize the practical application of electronic switches, photodetectors, low-power consumption information processing, direct energy conversion and the like; after being processed and formed, the paper core needs to be rolled up, and is generally wound on a cylindrical core tube (paper hollow winding drum) and then put on the market for sale.

The existing common film has a thickness generally larger than 10 microns, and the application of the automatic winding equipment is common, and the automatic winding equipment adopts direct winding operation on the outer surface of a hard winding drum. However, it is not directly applicable to winding operation of ultra-thin film (its thickness is generally less than 10 μm), and because of its large tension, when winding ultra-thin film, because the tension is difficult to control, and the uniformity of the tension in the length and width directions is difficult to control, the ultra-thin film is easy to wrinkle or tear, which affects the quality of the product.

The tension of the film unwinding part (attached to the film unwinding end) and the tension of the film winding part (attached to the film winding end) of the conventional common film winding device generally need to be adjusted to be consistent and uniform so as to avoid wrinkling or tearing of the film. When the film is rolled, in order to reduce the wrinkling or deformation of the film to the minimum, the film is enabled to be tightly attached to the main wheel as much as possible, so that great tension is generated at the film unwinding end, meanwhile, the tension of the film rolling end is increased, and the tension at each position in the width direction of the film is uneven due to the fact that the tension at the rolling end is too large, so that the wrinkling or even the tearing is easy to occur, and the product quality is influenced.

If the winding device is directly adjusted and the tension of the film winding end is reduced, the ultra-thin film may sag and wrinkle due to unbalanced tension between the two ends (i.e., the film unwinding portion and the film winding portion), so that the interlayer distance between the winding layers of the ultra-thin film becomes uneven and not dense, and the product quality may be affected.

Therefore, a winding drum which does not adjust winding equipment and only adjusts the structure of the winding drum needs to be researched, the existing common film winding equipment is directly suitable for ultrathin films through the improvement of the winding drum, crease resistance and tearing resistance can be realized in the winding working process, and the quality of products can be guaranteed, so that the purposes of the existing common film winding automation equipment are expanded, and the cost of production enterprises is reduced.
