Trolley type rapier tape guide rail of rapier loom

Abstract

The invention relates to a roller type rapier belt guide rail for a rapier loom, which comprises a rapier belt (1), pins (2), lateral guiding rollers (3), a rapier belt guide rail (4), a lower supporting roller (5) and a pin shaft (6). The roller type rapier belt guide rail is characterized in that the lateral guiding rollers (3) are arranged at left and right sides of the rapier belt guide rail (4) through the pins (2), the lower supporting roller (5) is arranged at the lower part of the rapier belt guide rail (4) through the pin shaft (6), the rapier belt (1) is arranged on the rapier belt guide rail (4) and the lower supporting roller (5) and arranged inside the lateral guiding rollers (3), and the rapier belt (1) is glidingly connected with the rapier belt guide rail (4), the lower supporting roller (5) and the lateral guiding rollers (3). The roller type rapier belt guide rail has the advantages that the roller type rapier belt guide rail has small running resistance and low energy consumption, solves the problems of positioning and abrasion in the rapier belt running process of the high-speed rapier loom, is favorable for improving running speed of the loom, and can prolong the service life of the rapier belt.

Description

technical field [0001] The invention belongs to rapier looms, in particular to a roller type rapier belt guide rail of a rapier loom. Background technique [0002] At present, the rapier belt guide rails of rapier looms at home and abroad mainly have two structures: [0003] The first is the integral sword belt guide rail, the sword belt and the sword belt guide rail are directly slidably connected, and its basic structure is as follows: Figure 4 shown. [0004] exist Figure 4 Middle, 7-first rapier rail, 8-first rapier [0005] There are two main types of integral rapier guide rails, the first one is machined from steel as a whole, and then surface treated. The guide rail groove is processed by a T-shaped milling cutter. The inner surface of the groove cannot be ground, and the surface roughness is poor. It belongs to sliding friction. As the speed of the sword belt increases, the sliding speed between the bottom surface of the sword belt and the sword belt guide rail ...

AI Technical Summary

Problems solved by technology

[0008] In this structure, the sword belt reciprocates in the groove formed by two pressure plates. The backing plate is generally made of non-metallic material with a small friction coefficient. When the sword belt slides over the surface of the backing plate, it is similar to the previous structure Compared with the friction resistance between the bottom surface of the sword belt and the backing plate, the effect of reducing the wear of the bottom surface of the sword belt is obvious. However, due to the limitation of the thickness of the sword belt, it is difficult to install wear-reducing materials on the side of the sword belt guide rail. The wear of the guide rail on the side of the sword belt is not reduced. Due to the difference in the size of the parts, the size of the guide rail groove is difficult to guarantee, and the processing technology is poor, so it is not suitable for mass production.
