Problems solved by technology

However, due to the differences in precision and supporting parts in the processing and production process of each production equipment and the influence of various factors, the front and rear tractors are at the same given speed and synchronously pull a cable during operation. The discreteness of the two equipment (parts processing and motors, etc.) will inevitably affect the cable tension change between the front and rear tractors during the operation and processing process, which will inevitably lead to poor quality of the produced cables.

Abstract

The invention discloses a tension constant control system for cable traction. The tension constant control system includes a pay-off machine, a front tractor, an extruder, a water tank, a back tractor, a pay-off rack and a take-up machine. A potentiometer is connected onto a current output terminal of a speed controller of the back tractor, and a cable located between the front tractor and the back tractor is connected with a tension potentiometer used for feeding back tension signals. The front tractor, the extruder and the back tractor are connected with a linkage synchronous controller through a lead. The tension potentiometer and the linkage synchronous controller are controlled by a PLC (Programmable Logic Controller). The tension constant control system has the advantages of being reasonable in structural design and stable in cable tension between the two tractors, and being capable of ensuring dynamic balance of the cable tension between the two tractors and providing reliable guarantee for automation and product quality in cable production.

Description

technical field [0001] The invention relates to a constant tension control system, in particular to a constant tension control system for cable traction. Background technique [0002] In the use category of wire and cable coating units, in order to ensure the quality of cable products during the production process, many customers often use front and rear traction to control the constant tension during the production process of the cable. That is to say, the same two tractors are used to synchronously draw the cables to be processed to ensure that the cable tension between the two tractors is constant, so as to improve the quality of the produced cables. However, due to the differences in precision and supporting parts in the processing and production process of each production equipment and the influence of various factors, the front and rear tractors are at the same given speed and synchronously pull a cable during operation. The discreteness of the two equipment (parts pr...
