Rigid tension control system for conveyer belt coating production line

Abstract

The present invention relates to a rigid tension control system for conveyer coating production line. Said system includes the following components: coil-releasing machine, coil release drawing machine, coating machine, heating equipment, fitting machine, rolling drawing machine, rolling machine, servo motors respectively for driving said various machines, several transition press rollers, several force-measuring rollers, several weighing sensors, force-measuring terminals and programmable controllers and several variable-frequency speed regulators. Said system is stable, can greatly raise production efficiency of production line and can save production cost.

Description

technical field [0001] The invention relates to a tension control system for a conveyor belt coating production line, in particular to a rigid tension control system for producing conveyor belts. Background technique [0002] The production process of plastic conveyor belts usually includes the following processes: plastic raw material formula to make paste, drying fabric core base cloth, coating cloth surface primer, coating laminating material, laminating, coating surface material, polishing or embossed patterns. Except that the process of making paste from the plastic raw material formula is not done on the coating production line, the other processes are carried out on the production line and all require tension control. [0003] The existing tension intelligent control system of the conveyor belt coating production line usually includes an unwinding machine, an unwinding tractor, an unwinding brake device, a tension roller, a tension control device, a winding tractor a...

AI Technical Summary

Problems solved by technology

The back pressure of the tension roller is controlled by the tension control device—the tension cylinder. Its power is very small. Although the air pressure of the tension cylinder can be adjusted manually, the back pressure of the tension roller is very unstable due to the large fluctuations in the output pressure of the air source air compressor. ; while the angle meter can only display the swing of the tension roller, but cannot participate in the control

[0004] The above-mentioned tension control system adopts flexible tension control technology, which can generate and control very small tension, which is only suitable for textile systems and plastic leather production; the control method is based on human feeling and experience, and there is no precision at all.
