Air-jet loom profiled steel reed defect mouth repairing process

Abstract

The invention discloses an air-jet loom profiled steel reed defect mouth repairing process which comprises the following steps of: (1) checking the two ends of a profiled steel reed airflow groove, and determining the defect mouth position of the profiled steel reed airflow groove; (2) adopting a grinding tool to grind the defect mouth position of the profiled steel reed airflow groove to and forth along the profiled steel reed length direction until the two edges of the defect mouth are in smooth transition; (3) rubbing a ground surface (which is caused by grinding) to and fro by using a honing stick so as to remove defective wools of the ground surface; (4) using an abrasive belt to penetrate through a gap between profiled steel reed sheets within a ground surface range, and utilizing the friction of the abrasive belt and the side walls of the profiled steel reed sheets to remove residual defective wools; and (5) polishing the ground surface of a profiled steel reed on an air sand blaster, and ensuring the ground surface to be smooth and fine. With the adoption of the repairing process, the profiled steel reed can be repaired, and the repaired profiled steel reed can satisfy the normal use of an air-jet loom.

Description

Technical field [0001] The invention relates to a process for repairing special-shaped steel reeds of air jet loom components, in particular to a process for repairing special-shaped steel reeds of air jet looms. Background technique [0002] In the field of textile technology, special-shaped steel reed is a common component on air-jet looms. The special-shaped steel reed is a long strip, including two support bars and several uniform special-shaped steel reed pieces arranged between the support bars. The gaps between the steel reeds pass through. The special-shaped steel reeds are provided with airflow grooves, and the airflow grooves of several special-shaped steel reeds are formed by long airflow grooves. The wefts conveyed by the airflow can pass through the airflow grooves. , The warp yarn and the weft yarn are compressed by the special-shaped steel reed and interwoven into a cloth. However, because the woven fabric has a certain elasticity, the woven fabric width is smalle...

AI Technical Summary

Problems solved by technology

However, due to the certain elasticity of the woven cloth, the width of the woven cloth is smaller than the length of the special-shaped reed, so that friction will occur between the warp yarn and the bottom of the airflow groove at the two ends of the special-shaped reed, and the special-shaped reed itself Driven to operate at a very high frequency, thereby amplifying the negative effect of the friction, the friction is easy to wear the bottom of the airflow groove at both ends of the special-shaped reed, resulting in a gap, that is, a relatively small gap, which is easy to cut off the warp yarn , so that the probability of thread breakage increases, so that the air-jet loom needs to be shut down frequently

[0003] At present, there is no good maintenance method for the special-shaped reed with defects, and the overall replacement is generally used, which increases the cost
