Safety roller for spinning machine drafting mechanism

Abstract

The invention discloses a safety roller for a spinning machine drafting mechanism, and mainly relates to the technical field of textile machinery. A bearing inner sleeve is integrally nested in an outer sleeve, a bearing is nested in the outer sleeve, and the two ends of the bearing abut against the outer sleeve and a first check ring respectively; a dust cover is clamped in the outer sleeve; a detection mechanism is arranged on one side of the outer sleeve, the detection mechanism comprises a temperature sensor, a humidity sensor and a smoke sensor; an automatic alerter is connected to the top of the detection mechanism; a protection layer is arranged on the surface of a shaft and composed of an acid-base corrosion resistance layer, a high temperature resistance layer and a wear resistance layer. The roller can perform enough compensation, the sealing property is good, the service life is long, the application arrange is wide, the safety is good, and it is guaranteed that spinning isperformed with high quality for a long time.

Description

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

AI Technical Summary

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 without fine-tuning, so it is convenient and quick to use, assemble, disassemble and maintain, with low maintenance cost, stable quality, strong implementability and wide application range; on the other hand, it has good sealing performance and is The dust cover well avoids the erosion of dust and impurities, and has a long service life, which reduces the number of grinding times and prolongs the service life; in addition, it monitors the environment around the top roller in real time through the detection mechanism, and automatically alarms in case of accidents such as fire The device responds immediately, thereby reminding the staff to make adjustments in time, which greatly improves the safety and greatly ensures the long-term efficient and stable operation of the spinning work; it greatly improves the weather resistance of the shaft through the protective layer, thus having a good High temperature resistance, wear resistance and acid and alkali resistance, durable
