Low-noise roller for spinning machine drafting mechanism

Abstract

The invention discloses a low-noise roller for a spinning machine drafting mechanism, and mainly relates to the technical field of textile machinery. A nylon ring sleeves the middle of a shaft, and the lower portion of a shaft sleeve is sleeved with the inner side of a bearing inner sleeve; the bearing inner sleeve is integrally nested in a bearing, the bearing is nested in an outer sleeve, and the two ends of the bearing abut against the outer sleeve and a first check ring respectively; a cushion is arranged between the bearing inner sleeve and the shaft sleeve, and the cushion comprises a foam plate and a damping material layer; a protection layer is arranged on the surface of the shaft and composed of an acid-base corrosion resistance layer, a high temperature resistance layer and a wear resistance layer; the surface of the outer sleeve is covered with a layer of high-hardness heat-resisting paint. The roller can perform enough compensation, the spinning quality is greatly guaranteed, the sealing property is good, safety and reliability are achieved, working noise is low, the service life is long, the application range is wide, and maintenance is conducted conveniently and rapidly.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a low-noise top roller used for a drafting mechanism of a spinning machine. Background technique [0002] Spinning machine is a kind of textile machinery that processes pre-oriented yarns such as polyester and nylon into different varieties and deniers through draft deformation. The drafting mechanism of the spinning machine must have sufficient holding force when drawing the tow. , so that the tow moves forward according to the surface speed of the roller, and minimizes the slipping of the tow in the drafting mechanism. The top roller belongs to the parts of the drafting mechanism, and its function is to press the tow on the roller to improve the holding force of the tow and reduce slipping. [0003] In recent years, with the continuous development of science and technology, related industries have higher and higher technical requirements for spinning machines. Howeve...

Problems solved by technology

The invention replaces the original hard connection between the shaft and the bearing by adding a rubber ring between the shaft and the inner sleeve of the bearing. Due to the elasticity of the rubber, the top roller can swing 360 degrees around the shaft, so the top roller can swing around the axis. 360-degree compensation avoids slipping, solves the problem of poor contact between the top roller and the roller, and greatly guarantees the quality of spinning; and it adopts a detachable combination design, the overall structure is simple, and can be It is directly installed on the pressure arm and used without fine-tuning, so it is convenient and quick to use, assemble, disassemble and maintain, with low maintenance cost in the later period, stable quality, strong implementability, and wide application range; it greatly improves the overall stability of the shaft through the protective layer. Weather resistance, so it has good high temperature resistance, wear resistance and acid and alkali resistance, and is durable; on the other hand, it greatly reduces the noise generated during the spinning process through the cushion pad, preventing the surrounding people from being affected Too much interference, but also plays a good role in shock absorption and buffering
