Problems solved by technology

[0004] Coil indentation is an important problem that restricts the yield of products. If it is not solved properly, it is easy to cause secondary damage to the strip steel
At present, some companies have developed a new type of sleeve with soft belt function, which can effectively solve the problem of indentation of the belt head. However, in the process of export belt threading, the belt head must be accurately pressed into the soft belt area of ​​the sleeve, which is difficult for electrical control. here comes the difficulty

Abstract

The invention discloses a self-threading tape positioning device of a soft tape sleeve in an outlet of a cold rolling and continuous annealing unit and a positioning method thereof, and relates to the technical field of strip steel reeling machines. The device comprises a mandrel, the soft tape sleeve, a reflective sheeting, a soft area, an outer supporting arm and a phototube, wherein the soft tape sleeve is sleeved at the outer side of the mandrel; the soft area is penetrated through the soft tape sleeve from front to back; the reflective sheeting is arranged at the front end, opposite to the soft area, of the soft tape sleeve; and the phototube is mounted on the outer supporting arm at the operation side of the soft tape sleeve. The soft area is arranged on the sleeve; the automatic control from leading positioning to the soft area is realized through the program modification; and a simple and efficient self-threading tape method is realized, so that the generation of impressions in the strip steel reeling process is reduced, the material is saved, the cost is decreased, and the production efficiency is guaranteed.

Description

[0001] technical field [0002] The invention relates to an automatic strip threading positioning device and a positioning method for a soft strip sleeve at the exit of a cold rolling continuous annealing unit, and belongs to the technical field of coiling machinery for strip steel. Background technique [0003] The continuous annealing unit belongs to the final output link in the cold rolling production process, and has a very obvious effect on improving the quality of cold rolled steel plates. The unit adopts the traditional coiling method, which will form a long coiling indentation (leader mark) on the strip steel of the inner ring. The length of the strip steel with indentation on each coil ranges from a few meters to more than ten meters. Every process of cold rolling must avoid the quality defects of strip steel in this process, and coiling indentation is the most common one. [0004] Coil indentation is an important problem that restricts the yield of products. If it...
