Description

technical field [0001] The invention belongs to the field of film conveying machinery and equipment, in particular to a film conveying device, which is mainly used in the field of continuous conveying and processing of films. Background technique [0002] A film is a thin and soft transparent sheet, mainly made of plastic, adhesive, rubber or other materials. The scientific explanation of the film is: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of the substrate. The film Material refers to a thin metal or organic layer with a thickness ranging from a single atom to a few millimeters. Thin films are widely used in electronics, machinery and printing industries, among which electronic semiconductor functional devices and optical coatings are the main applications of thin film technology. According to the classification of raw materials used, film materials can be divided into: polyethylene film, polypropylene film, polyvinyl chloride...

AI Technical Summary

Problems solved by technology

During the unwinding process of the existing film roll, the film mainly uses the pull of the subsequent process to realize the unwinding and transmission. When the subsequent process breaks down and needs to be temporarily stopped for processing, it is difficult to realize the fast and stable stop of the film roll. The roll will continue to rotate due to the rotational inertia, causing the film to be loose and scattered, causing the film to be skewed and twisted, which affects the accurate and smooth material guide transmission of the film. During the production and processing of the existing film, the film is unwound and transported Processing, after all the film wound on the film roll placed at the unwinding station is unwound and conveyed, a new film roll needs to be placed again at the unwinding station for transmission, and the existing film roll is changing During the transmission process, in order to ensure the continuity of the film transmission process, it is necessary to bond the tail end of the unwound film roll to the head end of the newly replaced film roll. The bonding process between the existing two rolls of film adopts Manually, it is necessary to pull the end of the newly replaced film roll smoothly, so that the ends of the two rolls of film are overlapped and bonded. The existing film bonding is manually operated, and the operation efficiency of film bonding is relatively low. Low, it is difficult to achieve efficient and stable film bonding processing, the bonding process is complicated, and the time for bonding the ends of the film on both sides is long, resulting in the need to stop operation during the process of replacing the film roll, which reduces the efficiency of film production and processing, and the two sides of the film The bonding of the side ends is manually operated, and the quality of the film bonding is difficult to be guaranteed. It is easy to cause the film to be skewed and wrinkled during the film bonding process, and it is difficult to achieve smooth and accurate bonding and continuous transmission of the film, which cannot meet the requirements of production and use. need
