Tape head centring device for power reels

Abstract

The invention discloses a tape head centring device for a power reels. The tape head centring device comprises an operating side clamping device and a driving side clamping device which are oppositely arranged, wherein the operating side clamping device is provided with an operating side rack which can slip along a frame, and is fixedly provided with an operating side arm blocking plate, and the operating side arm blocking plate is provided with an operating side pressed block; the driving side clamping device is provided with a driving side rack which can slip along the frame and is fixedly provided with a driving side arm blocking plate, and the driving side arm blocking plate is provided with a driving side pressed block; and a reversing mechanism comprises a reversing shaft which is provided with a worm wheel and a gear, the worm wheel is meshed and matched with one end of a screw rod, the other end of the screw rod is connected with a driving device, and the two sides of the gear are respectively meshed and matched with the operating side rack and the driving side rack. The tape head centring device provided by the invention has the advantages that the structure is simple, the synchronous centering property is good, and the problem of deflection as a tape head is not positioned on a centre line position when a tape steel enters a reeling machine can be effectively solved; and the defect of inner spillage is prevented, judging waste quantity and crease proportion of a galvanized plate are reduced, and the yield is improved.

Description

technical field [0001] The invention relates to a forced centering device, in particular to a belt head centering device for a strip steel coiler which can realize automatic centering of the strip head after the strip steel is cut, and facilitate the neat coiling of the strip steel by the coiler. Background technique [0002] In order to realize storage and transshipment of cold-rolled steel strip, the processed products need to be coiled. However, the tape head of some specifications is hard or has a ladle itself. After being cut, it is easy to form a sickle-shaped bend. Because the deflection occurs in the first few turns of coiling and building, the overflow defect in the strip will occur; according to the different degrees of skew, the overflow situation shows a strengthening trend. Therefore, to prevent creasing and unnecessary scrap, it is imperative to ensure that the strip head is forcibly centered and the strip inside the pinch rolls is straight before the pinch ro...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the existing cold-rolled strip cannot ensure the centering of the strip before entering the coiler, and provide a strip-coiler centering device with simple structure, remarkable effect and good synchronous performance
