Constant-tension winding and unwinding hardware control system with synchronous winding and unwinding function

Abstract

The invention discloses a constant-tension winding and unwinding hardware control system with a synchronous winding and unwinding function, wherein the system comprises a PLC, the PLC is electrically connected with a first timer and a second timer respectively, and the PLC is bidirectionally and electrically connected with a first distance sensor, a second distance sensor, a magnetic powder brake, a magnetic powder clutch, a displayer and two tension controllers respectively; and the first timer and the second timer are electrically connected with the magnetic powder brake and the magnetic powder clutch respectively. The distance sensors are arranged to assist the tension controllers in use, the distance sensors are used for measuring the specific fixed distance between the distance sensors and a material in advance, the drooping condition of the material can be measured in time at the moment that the tension drops, the tension controllers adjust the tension in time, the drooping condition of the material is avoided, long-time operation of constant tension of the system is guaranteed, the winding mechanism is prevented from winding the material which does not meet requirements when the material droops, and the quality of the material is improved.

Description

technical field [0001] The invention relates to the technical field of control systems, in particular to a constant tension winding and unwinding hardware control system with synchronous winding and unwinding functions. Background technique [0002] The tension control system is an automatic control system that realizes constant tension or taper tension control. Its main function is to realize the synchronization between rolls and the uniform control of winding and unwinding. It is currently mainly used in metallurgy, papermaking, film, dyeing and finishing, Weaving, plastic, wire and other equipment. [0003] In many industries of industrial production, winding control problems are often encountered. For example, in the production process of paper, textiles, plastic films, wires, printed matter, tapes, metal strips and wires, etc., the uncoiling and winding tension of strips or wires is very important to the quality of the product, so constant tension control is required. ...
