High-usage rubber-covered roll used for spinner drafting assembly

The invention relates to a rubber roller with a high utilization rate used for the drafting device of a spinning machine and belongs to the field of textile technology. The invention is used for solving the problem that a rubber roller has a low utilization rate due to abrasion. The technical proposal is that the invention consists of a rubber roller body and a rubber roller shaft. The rubber roller body is symmetrically arranged on both ends of the rubber roller shaft. A bearing is arranged inside the rubber roller body. A grip cross-piece is arranged at the middle part of the rubber roller shaft corresponding to the clamping frame of a cocket centring of the drafting device. After the rubber roller is improved, the axial position of the rubber roller relative to the clamping frame is adjustable. The invention enlarges the drafting migration distance of the surface of the rubber roller, improves the utilization rate of the rubber roller and prolongs the service life and manufacturing period of the rubber rol
