High-speed rapier jacquard towel loom and beating-up system thereof

Abstract

The invention relates to a high-speed rapier jacquard towel loom and a beating-up system thereof, and belongs to the field of textile machinery. The loom comprises a beating-up mechanism, an intelligent controller, a motor, force sensor systems and an angle sensor; the beating-up mechanism comprises a conjugate cam assembly and a beating-up swinging shaft assembly, the beating-up swinging shaft assembly sequentially comprises a reed, a guide rail beam, an aluminum support arm and a rocking shaft, and the conjugate cam assembly comprises a main cam, a subsidiary cam, a rolling wheel A, a rolling wheel B and a rocking shaft; the main cam is in contact with the the rolling wheel A, the subsidiary cam is in contact with the the rolling wheel B, a conjugate cam shaft is connected with a main transmission shaft, the reed is driven by a motor, the motor is connected with a controller, the controller can timely adjust the rotation speed of the motor according to the change of the heald tension, fabric tension and woven opening angle, and therefore the reciprocating beating-up speed of the reed is adjusted. The loom can precisely control the beating-up motion, the performance of the loom and the quality of fabric are improved, and the intelligence and automation level of the loom are improved.

Description

technical field [0001] The invention relates to a high-speed rapier jacquard towel loom and its beating system, in particular to the technical field of improvement of the beating mechanism of the high-speed rapier loom. Background technique [0002] China's textile industry has made immeasurable contributions to enhancing national power and strength, and textile machinery occupies an important position in the textile industry. However, among the rapier looms, more than 90% of the high-end models are imported. The beating mechanism is a key part of the rapier loom, and its motion performance directly determines the quality of the fabric as well as the quality and efficiency of the rapier loom. [0003] The conjugate cam beating mechanism is a common beating mechanism of modern looms. The conjugate cam is a geometric locking mechanism with high motion accuracy and is suitable for high- and medium-load high-speed occasions. The primary cam and secondary cam of the conjugate c...

AI Technical Summary

Problems solved by technology

The performance of the conjugate cam mechanism processed in my country is poor, and it is difficult to meet the high-speed operation requirements of the rapier loom

Usually the conjugate cam mechanism adopts the mechanical beating method. Due to the inherent factors of mechanical beating, the performance of the beating mechanism can be improved to a certain extent through design and improvement, but it is difficult to fundamentally solve the problem of high speed and high precision.

In addition, with the change of yarn and fabric fall, the movement law of the beating mechanism cannot be adjusted intelligently, which is also an important factor restricting the movement performance
