A Two-Stage Buffer Positive Pile Warp Let-Off Mechanism

Abstract

A two-stage buffering positive cashmere warp let-off mechanism, which relates to a towel loom, includes two wall panels on the left and right, a pile warp shaft is arranged on the upper side of the wall board, and an upper reinforcement mechanism, an upper buffer mechanism and a pile shaft are installed on the wall board The counting mechanism and the upper reinforcement mechanism ensure that the pile warp beam and the active let-off mechanism will not vibrate when they are working. The pile shaft counting mechanism is located between the pile warp shaft and the upper buffer mechanism. A lower buffer mechanism is arranged on the wall plate, the lower buffer mechanism is located below the upper buffer mechanism, and the upper buffer mechanism is connected with a tension sensing mechanism. The structure of the present invention is relatively durable and reasonable, actively and actively cooperates with the warp let-off motor to send out the pile warp yarn when the loop is raised, after the end of the loop, it returns softly and quickly to wait for the weaving of the next loop, and feedbacks the pile warp in time Tension and warp delivery of pile warp beam.

Description

technical field [0001] The invention relates to a towel loom, in particular to a two-stage buffering active pile warp let-off mechanism. Background technique [0002] As we all know, looms on the market have two types of terry mechanisms—cloth-moving and reed-moving. Any type of terry mechanism requires a positive pile warp let-off mechanism. The active style is mainly reflected in the sense of tension changes and the mutual cooperation with other institutions. [0003] At present, there are single-spring cashmere warp let-off mechanisms in the mainstream market; active cashmere warp let-off mechanisms with primary buffer elastic devices plus pull or compression springs and driven swing rods. The first mechanism completely adjusts the tension of the pile warp through the performance of the spring. Due to the quality problem or aging phenomenon of the spring, for relatively thin towel fabrics, when the swing lever is reset, the rigidity is too large, and there is a certain p...

AI Technical Summary

Problems solved by technology

The second type of warp let-off mechanism with a first-level buffer device has wide applicability. The disadvantage is that the life of the buffer tube or elastic plate (strip) is limited, and the damage rate of the heavier fabric is heavier. There are certain differences in the cooperation of the fleece warp let-off servo

Therefore, the two types of pile warp mechanisms are reflected on the cloth surface, and there are slight flaws in the evenness of the loops.
