Warp let-off worm for loom

Abstract

The invention discloses a let-off worm for a loom. The let-off worm comprises a body worm and a driving rotor. A fixed brake pad is arranged inside the body worm. A driven friction disc is installed on one side of the fixed brake pad. A hollow shaft is installed in the center of the body worm. A let-off side shaft is installed on one side of the hollow shaft. A connecting rod is installed on the other side of the hollow shaft. A brake ring is installed on the outer wall face of the body worm. A rigid spring is installed on one side of the brake ring. A let-off gear is installed on the other side of the brake ring. Due to the fact that the rigid spring is arranged on the inner side of the brake ring, the good buffer performance and adaptability of the let-off worm in the working process can be ensured, the phenomenon that a let-off basket is disengaged is avoided, and therefore the working efficiency and working quality can be improved; meanwhile, the brake ring and the fixed brake pad are arranged, so that the brake efficiency of the let-off worm can be improved, the working operation effect is more accurate, and then the quality and safety are improved.

Description

technical field [0001] The invention relates to the technical field of loom accessories, in particular to a let-off worm for a loom. Background technique [0002] Looms are also called spinning machines, looms, cotton spinning machines, etc. The early looms were all driven by manpower. Shuttleless loom technology has been researched since the 19th century, and has been gradually introduced to the international market since the 1950s. Since the 1970s, many new shuttleless looms have been put into the market one after another. Shuttleless looms have achieved remarkable results in improving fabrics and increasing the efficiency of looms, and have been widely used in countries all over the world, and have accelerated the process of weaving equipment transformation. The share of shuttleless looms in many developed countries has reached about 80%. There has been a general trend of replacing shuttle looms with shuttleless looms. [0003] The earliest loom was a squatting loom si...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a warp let-off worm for looms, to solve the problem that the warp let-off speed proposed in the above background technology often cannot keep up with the weaving speed, thus causing problems with the tightness of the cloth surface and affecting the effect of weaving. The phenomenon that the heald frame is taken off, so a let-off worm for loom is needed
