Repair poking knife for special-shaped reed of air-jet loom

Abstract

The invention provides a repair poking knife for a special-shaped reed of an air-jet loom. The repair poking knife is characterized in that the special-shaped reed is vertically arranged between an upper beam and a lower beam, wherein the upper beam and the lower beam are parallel; for the deformed special-shaped reed, the upper portion of the deformed special-shaped reed is clamped through a reed clamp, the poking knife penetrates a warp sheet, the portion of the deformed special-shaped reed is clamped through a concave groove in the front end of the repair poking knife for the special-shaped reed, the special-shaped reed is twisted in the direction opposite to the deformation direction with uniform force, and then the special-shaped reed is restored to a normal state; and the thickness of the rear end of the repair poking knife for the special-shaped reed is larger than that of the front end of the repair poking knife, a trapezoidal blade is formed, a groove is formed in the middle of the cross section of the front end of the trapezoidal blade, and the repair poking knife for the special-shaped reed is formed by the trapezoidal blade and the groove. According to the repair poking knife for the special-shaped reed, repair on the special-shaped reed of the air-jet loom by shaft cutting off-loom is avoided, repair time is shortened, and production cost is reduced.

Description

technical field [0001] The invention relates to a reed repair tool for an air-jet loom, in particular to a knife for repairing the reed path of a special-shaped reed (lower layer) of an air-jet loom. Background technique [0002] In the weaving production process, the profiled reed of the air-jet loom is an important part for weft insertion and beating-up of the loom. The quality and running status of the profiled reed are directly related to the efficiency of the loom and the quality of the fabric. The special-shaped reed is a long rectangle, including two upper and lower support bars and special-shaped reed pieces fixed evenly between the support bars. The warp yarn passes through the reed pieces (reed teeth) according to certain technological requirements; The process is the process in which the warp and weft yarns interweave each other according to certain rules. The interweaving will inevitably cause buckling of the warp and weft yarns, which forms the warp and weft wea...

Problems solved by technology

However, the distance between the holding point of the temple and the cloth surface is 10mm-20mm from the weaving fell. When beating up, the tension of the warp yarns at the side is much larger than that of the warp yarns at the middle part, and the inclination angle is also larger. The pressure and friction of the edge reed teeth are the largest. Therefore, under the action of long-term violent beating motion, the ordinary reed teeth adjacent to the edge of the reed and the reinforced reed teeth are easily deformed to produce reed roads, resulting in reed roads on the cloth surface. Defects, when the reed teeth on the edge of the reed have a reed road problem during the weaving production process, it is generally used to cut off all the warp yarns of the loom, that is, cut the shaft and take it off the loom. After the reed is repaired, re-reed and put on the loom This repair method affects the quality of the cloth surface, and the repair time is long, which reduces the production efficiency and increases the production cost
