Steel cord surface defect and wire breakage detection and protection apparatus

Abstract

The invention discloses a steel cord surface defect and wire breakage detection and protection apparatus, comprising a stranding machine tool and a steel cord; a winding wheel and a traction wheel are mounted on the stranding machine tool. The steel cord surface defect and wire breakage detection and protection apparatus also comprises a fixing support mounted between the winding wheel and the traction wheel on the stranding machine tool; an upper positioning wheel, a lower positioning wheel, a fixed sliding sleeve and a strong magnetism support are fixed on the fixing support, the upper positioning wheel is disposed above the fixed sliding sleeve, the lower positioning wheel is disposed below the fixed sliding sleeve, the strong magnetism support is fixed on the fixing support, the bottom end of the strong magnetism support is connected with the top end of the fixed sliding sleeve, a left metal block and a right metal block in symmetrical distribution are nested in the fixed sliding sleeve, a proximity switch is also arranged below the fixed sliding sleeve, the proximity switch is fixed on the fixing support, and the proximity switch is in communication connection with the stranding machine tool through a PLC (programmable logic controller). The apparatus of the invention has no need for rewinding, and may gain reduced labor cost and reduced energy cost for a machine tool.

Description

technical field [0001] The invention relates to a detection device for a double-twisting machine in the plying and rope-forming process of steel cord production, in particular to a detection and protection device for steel cord surface defects and broken wires, which is mainly used for detecting wire products such as steel cord produced by a double-twisting machine Surface defect and broken wire, joint detection technology field. Background technique [0002] During the processing of steel cord and other wire products, due to the influence of factors such as raw materials, different structures, and manufacturing process control during the twisting of steel cord and other wire products, the twisted surface of steel cord and other wire products There are various defects. Such as: twisted steel cord and other wire products such as surface core turning, back wire (back strand); broken wire and wheel-changing joints and other defects. In the national standard GB / T11181-2016 ste...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a steel cord surface defect and broken wire detection and protection device, in view of the surface defect detection problems existing in the twisting process of existing steel cords and other wire products, using mechanical physical devices and electrical control The device detects surface defects, broken wires and joints of steel cords. This detection and protection device can effectively solve the detection problems of surface defects existing in the twisting process of existing steel cords and other wire products. It has high detection sensitivity and is easy to operate.
