Spindle tape tension device of ring spinning frame

Abstract

The invention relates to a spindle tape tension device of a ring spinning frame, wherein a main shaft (3) and a tension pulley shaft (5) are arranged on a main shaft bearing seat (12); a rolling disc (4) is arranged on the main shaft (3); a positioning pin (6) is arranged on the tension pulley shaft (5); a support ring (7) is arranged on the tension pulley shaft (5) and a positioning pin (6); a bracket (8) is arranged on the support ring (7); a heavy punch (11) is arranged at one end of the bracket (8); the tension pulley frame (9) and a spindle tape tension pulley (10) are arranged at the other end of the bracket (8); a spindle (1) is arranged on a keel (13); and a spindle tape (2) is arranged on the rolling disc (4), the spindle tape tension pulley (10) and four spindles (1). With the adoption of the spindle tape tension device, the requirements on tension stabilization and consistence of the spindle tape of the spinning frame can be met.

Description

technical field [0001] The invention belongs to a part of a textile machine, in particular to a tensioning device for a spindle belt of a ring spinning frame. Background technique [0002] The ring spinning frame is an important equipment with a large area and a wide range of production processes in the textile industry. Its performance directly affects the quality of the yarn, the amount of labor, the labor intensity of the workers, management, and economic benefits. The level directly affects the development of the cotton spinning industry. [0003] With the upgrading of the textile industry, users have higher and higher requirements for textile machinery. Spinning frame long car with collective doffing has become the mainstream in today's market. The number of spindles has gradually expanded, and the current maximum number of spindles has reached 1632 spindles. The spindle drive of the widely used ring spinning frame is driven by a single tension wheel with a group of ...

AI Technical Summary

Problems solved by technology

According to the calculation of 1200 spindles per spinning frame, 300 sets of spindle belt tension devices are needed. In order to ensure that the spindle belt does not fall off during operation, the spindle belt tension wheel needs to have a reasonable space position, and the support arm 24 and bracket bolts must be adjusted one by one. 25. Satisfy the front, rear, left, and right spatial positions of the spindle belt tension wheel 27; at the same time, the tension of the spindle belt depends on adjusting the position of the weight on the adjustment frame, and then tightening. There are thirteen scale positions on the adjustment frame, and the density is large , These are all adjusted by the workers during on-site installation, the workload is heavy, and it is difficult to do well, resulting in different positions of the tension pulley, inconsistent tension of the spindle belt, or even generally too large, and increased power consumption of the whole machine

In addition, the structure of the spindle tape tension device is complicated, the support arm and the adjustment frame are poor in workmanship, the distribution of the force arm is unreasonable, and the weight of the heavy hammer is required to meet the tension of the spindle tape. The cost of the whole machine is very high, which restricts the development of the spinning frame.
