Stretching auxiliary spraying system for reducing length of waste selvage yarns of air-jet loom

Abstract

The invention belongs to the technical field of textile equipment, and particularly relates to a stretching auxiliary spraying system for reducing the length of waste selvage yarns of an air-jet loom.The stretching auxiliary spraying system comprises a reed base, an auxiliary spraying device, a photoelectric weft detector and a stretching auxiliary spraying channel, the auxiliary spraying devicecomprises a spraying pipe and a base, a mounting hole is formed in the base, the spraying pipe penetrates the mounting hole and is fixed onto the base, a circular pipe, a transition pipe and a flat pipe are sequentially connected from bottom to top to form the spraying pipe, the flat pipe is perpendicular to the reed base, a nozzle is horizontally arranged at the top of the flat pipe, the distancebetween the nozzle and the central axis of the mounting hole is 4-8mm, and an airflow outlet of the nozzle faces the photoelectric weft detector and the stretching auxiliary spraying channel. By improving the structure of the auxiliary spraying device, sufficient straightening of weft yarns and good interweaving of the waste selvage yarns can be ensured, the length of the waste selvage yarns is reduced, cost is saved, the stretching auxiliary spraying system has considerable economic benefits, weaving weft shrinkage is reduced, and quality is improved.

Description

technical field [0001] The invention belongs to the technical field of textile equipment, and in particular relates to a stretching auxiliary spraying system for reducing the length of waste side yarns of an air-jet loom. Background technique [0002] The air-jet loom is a commonly used machine for textile weaving, and the waste edge yarn, as its inevitable product, is an important cost index for enterprise management and control. With the rise of raw material costs, the proportion of waste edge yarn in the consumption of finished products is also increasing big. During the production of gray fabrics on the air-jet loom, due to the insufficient traction of the airflow at the right end (free end) of the gray fabric to the weft yarns, the weft yarns retract before the end of weft insertion, and the reed weaves the weft yarns that have not been fully stretched after retraction into the cloth to form Weft shrinkage, in order to ensure that the weft yarn has sufficient traction ...

Problems solved by technology

During the production of gray fabrics on the air-jet loom, due to the insufficient traction of the airflow at the right end (free end) of the gray fabric to the weft yarns, the weft yarns retract before the end of weft insertion, and the reed weaves the weft yarns that have not been fully stretched after retraction into the cloth to form Weft shrinkage, in order to ensure that the weft yarn has sufficient traction and does not shrink back, it is necessary to use stretching auxiliary spraying, while the traditional stretching auxiliary spraying will increase the loss of waste edge yarn by 40%, which affects the efficiency of air-jet looms and the quality of gray fabrics
