Leather roller with monitoring function and for drafting mechanism of spinning machine

Abstract

The invention discloses a leather roller with a monitoring function and for a drafting mechanism of a spinning machine, and mainly relates to the technical field of textile machinery. The middle of ashaft is sleeved with a nylon ring, and the lower portion of a shaft sleeve is sleeved with a bearing inner sleeve; the whole bearing inner sleeve is sleeved with bearings, the bearings are sleeved with an outer sleeve, and the two ends of each bearing abut against the outer sleeve and a first retaining ring respectively; one side of the outer sleeve is provided with a visual sensor connected withan external displayer; the surface of the shaft is provided with a protective layer, and the protective layer is composed of an acid and alkali corrosion resistant layer, a high temperature resistantlayer and a wear resistant layer; the acid and alkali corrosion resistant layer is an epoxy resin coating, the high temperature resistance layer is a polyurethane layer, and the wear resistant layeris a high manganese steel layer. The leather roller can achieve sufficient compensation, the spinning quality is greatly ensured, and the leather roller is high in sealing property, long in service life, wide in application range and good in safety.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a top roller with a monitoring function 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 slippage. [0003] In recent years, with the continuous development of science and technology, related industries have higher and higher technical requirements for spinning mach...

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, acid and alkali resistance, and durable; on the other hand, the staff can monitor the specific working conditions of the spinning machine in real time through the external display, thereby improving the spinning work. Safety and accuracy, prevent accidents, and greatly ensure the long-term efficient and stable spinning machine
