Storage wire limit control device

Abstract

The invention discloses a storage wire limit control device which comprises a storage wire frame device, an industrial control system and a limit warming detector. The storage wire frame device comprises a storage wire frame body, a storage wire wheel set and a linkage plate, the storage wire frame body comprises a beam and a vertical column, the beam is fixed on a horizontal plane through the vertical column, the storage wire wheel set is arranged below the beam through the linkage plate, the limit warming detector is arranged on one side of the beam, the industrial control system comprises a host frequency converter and a power mechanism, the linkage plate and the limit warming detector are respectively connected with the host frequency converter, and the host frequency converter is connected with the power mechanism and controls the power mechanism to operate. According to the storage wire limit control device, positions are detected by a displacement sensor and the limit warming detector, signals can be rapidly and accurately fed back to the industrial control system by the aid of a double detection mode, operation speed of a motor is controlled by the industrial control system, dynamic closed loop control is achieved, shortcomings caused by rapidly elongating are overcome, winding efficiency and winding quality of cables are effectively improved, and enterprise production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to a wire storage limit control device. Background technique [0002] The advent of wires and cables has greatly improved the safety of power generation, transmission, transformation, supply, distribution, and use. In order to ensure the safety performance of wires and cables, the outer sides of wires and cables are equipped with protective coverings composed of insulating sheaths. Layer, the existing protective layer extrusion process adopts multiple extrusion molding, after extrusion molding, it needs to be wound on the I-shaped take-up reel; The take-up speed is often inconsistent, so it is necessary to set up a buffer adjustment work by setting a storage rack between the production line and the take-up reel. [0003] As we all know, due to the needs of production, the winding speed of the storage rack can reach 1000m / min. In the prior art, a potentiometer is usually u...

AI Technical Summary

Problems solved by technology

In the prior art, a potentiometer is usually used for limit warning, but because the potentiometer is in the process of continuous movement, it is easy to wear and damage, and needs to be replaced frequently; and the length of the winding cable will gradually change, so it is necessary to install the potentiometer The position is constantly adjusted, which increases maintenance and operating costs
