Abstract

The invention provides a steel belt retractor, comprising a winding shaft, a bracket and a brake device, the bracket supports both ends of the winding shaft, a brake device is arranged on the bracket at one end of the winding shaft, and the brake device It includes a brake disc, a brake disc head, a brake lever and a weight. One end of the brake lever is hinged to the brake disc head, the middle part of the brake lever is hinged to the bracket, and a weight is hung on the other end. The other end of the brake pad head is provided with the brake pad; the low cost of equipment manufacturing is realized, the structure is simple, the transportation is convenient, and the steel belt is prevented from sagging when retracting and unwinding.

Description

technical field [0001] The invention relates to a retracting device, in particular to a steel strip winding and unwinding device. Background technique [0002] At present, the commonly used steel belt retracting and unwinding equipment has the same speed during the steel strip winding process, and as the steel belt is wound less and less on the retracting and unwinding equipment, the speed of the retracting and unwinding equipment will change. , which causes a large change in the tension of the steel strip, which greatly affects the production quality of the steel strip; and there is no support point for fixing the steel strip on the rollers of the retracting and unwinding equipment, which may easily cause the steel strip to slip when winding the steel strip. It cannot be tightened; in addition, after winding all the steel belts on the winding equipment, the weight and volume are relatively large, and it is difficult to move, so it is quite labor-intensive and time-consu...
