Warp alignment stop device for weaving machine

Abstract

The invention provides a warp alignment stop device for a weaving machine. The warp alignment stop device is mounted on a warp between a let-off mechanism and an opening mechanism of the weaving machine and comprises a fixed connection strip, fixed sleeves, a movable connection strip, movable sleeves and a pulling device, the fixed sleeves are made of elastic materials, the appearance of each fixed sleeve is conical, through holes are arranged on the fixed sleeves along the axes, cutting grooves are uniformly distributed at the conical ends of the fixed sleeves, the warp penetrates through the middles of the fixed sleeves, the movable sleeves are sleeved on the fixed sleeves and are made of rigid materials, and the pulling device is connected with the movable connection strip and pulls the movable connection strip to drive the movable sleeves to move along the axes of the fixed sleeves. The warp can be uniformly distributed before entering the opening mechanism through the equidistant fixed sleeves and can be timely stopped when the weaving machine goes wrong, and kink of the warp is prevented.

Description

[0001] technical field [0002] The invention belongs to the technical field of textiles, and in particular relates to a loom warp alignment stop device. Background technique [0003] Since the industrial revolution, looms have gradually developed from the original manual operation to mechanization, and rapier looms, air-jet looms, water-jet looms, projectile looms, etc. have appeared. In current production, there are various types of looms , but its basic principle structure is roughly the same. It mainly includes the fabric structure, which separates the warp yarn up and down to form a shed opening for weft insertion; the weft insertion mechanism that introduces the weft yarn into the shed opening; pushes the weft yarn introduced into the shed opening to the weaving opening to form a weft beating mechanism for the fabric; The take-up mechanism that leads the woven fabric away from the fabric forming area and rolls it into a certain package; the warp let-off mechanism tha...

Problems solved by technology

[0004] Among them, the quality of the let-off mechanism directly affects the quality of the produced cloth, but the current let-off mechanism is usually only designed for warp threads of a certain thickness. The warp let-off mechanism cannot align the warp thread well, which affects the quality of the produced cloth, and it is difficult for the let-off device to stop the warp thread during its movement. Once the loom has an error during operation , and the continued operation of the let-off device will cause errors in the cloth being woven, seriously affecting the quality of the cloth, and once the individual warp threads are twisted, the operator has to stop and rearrange the warp threads before weaving. wasted a lot of time
