Problems solved by technology

[0003] In short, the frequent problems of the old worm gear transmission method are: the main transmission shaft is broken, the friction plate for adjusting the tension is easy to fail, the worm gear is worn, the tension value of each transmission point is different, and there is no visual display of the tension value. It is also difficult to ensure uniform tension at each point, and the worm gear and worm often need to be maintained with lubricating oil

Abstract

The invention discloses a tension control system, which comprises a driving roller, a driven roller and a tension adjusting device, and is characterized in that in a closed-loop full automatic tension control system formed by a tension sensor on a position of a film, a tension converter, a special winding frequency converter, an electric motor, the driving roller, a group of driven rollers and the tension sensor on the position of the film; the tension sensor of the film, the tension converter and the special winding frequency converter are connected through signal wires in turn; the special winding frequency converter is connected with the electric motor through a cable; the electric motor is directly connected to the driving roller; and the driving roller and the driven rollers are connected by chain wheels. The tension control system adopts frequency conversion winding control technology to overcome the defects of the prior transmission mode, the tension on each position of a production line can be displayed intuitively, and the integral tension of the whole line can be adjusted. The tension control system can be widely applied to the transmission control of the production lines for processing aluminum foils, films, textiles, printing, plastics, and the like.

Description

technical field [0001] The invention relates to a tension control system, in particular to a tension control system for moving, driving or winding thin objects such as films during the production process, especially a foil tension control system for the aluminum foil production process. Background technique [0002] The production process of electronic aluminum foil requires relatively stable tension to produce good products. The problem of stable tension control has always plagued the aluminum foil production industry. The current transmission mode in production is: driven by a main shaft, each transmission point drives each roller to operate with a worm gear structure, and the tension of the roller is adjusted by the tension friction plate that is squeezed and connected with the roller shaft. In this transmission mode, the mechanical loss of the main shaft and the speed difference control mechanism is large, and it is difficult to perform speed control and tension control ...
