Active and passive adjustment combined thin film tensioning device

Abstract

The invention discloses an active and passive adjustment combined film tensioning device which comprises a device body, an alarm assembly is arranged on the rear end face of the device body, a film outlet is formed in the right end face of the device body, and a mounting groove is formed in the position, close to the upper end, of the left end face of the device body. A film guide assembly is arranged in the device main body; the tensioning assembly is arranged in the device main body; according to the technical key points, the active and passive adjustment combined thin film tensioning device adopts segmented adjustment, so that the influence on a thin film caused by overlarge one-time adjustment can be avoided, the passive adjustment assembly is always in a dynamic adjustment state during adjustment, and adaptive adjustment can be performed according to different thin film tension; the fluctuation interval of the tension degree of the thin film adjusted by the passive adjusting assembly is small, the tension can be accurately adjusted by combining with further adjustment of the active adjusting assembly, the tension degree of the thin film can be accurately regulated and controlled, and the adjusting effect of the tension degree of the thin film is good.

Description

technical field [0001] The invention belongs to the field of film production, in particular to a film tensioning device combining active and passive adjustment. Background technique [0002] A film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials. Thin film is scientifically explained as: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate. Example: optical film, composite film, superconducting film, polyester film, nylon film, plastic film, etc. Films are widely used in electronics, machinery, printing and other industries. [0003] With the development of society, the requirements for thin films are also constantly improving. People have developed thin films with different functions in various fields. With the rapid development of various fields, the demand for thin films in various fields is constantly increasing. In order to meet people's requirements, people have invented some...

AI Technical Summary

Problems solved by technology

[0005] However, it has been found through research that the existing film tensioning device has certain disadvantages in use;

[0006] 1. Most of the existing film tensioning devices use one-time tension adjustment, and the tension adjustment range is large, and the film is prone to damage during adjustment, which does not meet the requirements for film tension adjustment;

[0007] There is also a small part of film tensioning equipment that uses secondary tension adjustment, but it is active adjustment for film tension adjustment, which is only suitable for the situation where the produced film tension is relatively uniform, such as film release In the actual production process, there is a certain floating space in the production speed of the production equipment, and there is room for fluctuation in the tension of the produced film. In this case, the tension adjustment accuracy of this part of the film tensioning equipment is not high.

[0008] 2. The width of the film is different, but the length of the guide roller of the film tensioning device combined with active and passive adjustment is uniform, and its position is prone to deviation during use, and the film moves at a fast speed. When there is a deviation, tension adjustment cannot adjust the film tension. Effect
