A material strip travel length measuring assembly

Abstract

The utility model discloses a kind of material belt advancing length-measuring subassembly, including installation component;Two sides lower end of installation component are equipped with installation side plate, rotation is equipped with measuring roller between installation side plate, and the shaft of measuring roller extends out corresponding installation side plate and is equipped with encoder, and encoder is electrically connected with external controller;Measuring roller outside is equipped with rubber coating, and rubber coating outside is equipped with grid pattern;Measuring roller below rotation is equipped with press roll, and press roll elastically extrudes measuring roller.The utility model is equipped with the press roll of elastic resistance, can resist pressure material belt in advancing process, increase the contact area and friction force of material belt and measuring roller, reduce relative sliding;Measuring roller outside is equipped with rubber coating and grid pattern, further improve the friction force between material belt and measuring roller, avoid cumulative error, improve measurement accuracy.
