Reed opening and weft inserting auxiliary mechanism for air jet loom

Abstract

The invention discloses a reed opening and weft inserting auxiliary mechanism for an air jet loom. The reed opening and weft inserting auxiliary mechanism is characterized by comprising a bearing seat assembly, a cam, a swing arm and an auxiliary reed groove, wherein the bearing seat assembly is fixedly arranged on a rack of the air jet loom and is hollowly sleeved on a beating-up shaft of the air jet loom; the bearing seat assembly is provided with a cam supporting block and the cam is connected with the cam supporting block through a cam connecting block; the swing arm is fixed on the beating-up shaft through a swing arm bracket; one end of the swing arm is provided with an idler wheel and the idler wheel is matched with the cam; and the other end of the swing arm is connected with the auxiliary reed groove. With the adoption of the air jet loom disclosed by the invention, a through air channel is formed by the whole reed groove in a weft insertion processing period so as to guarantee smooth air flow and ensure the weft insertion to be smoother, so that the operation of the loom is more stable and reliable. Furthermore, the reed opening and weft inserting auxiliary mechanism has the advantages of compact structure, convenience for adjustment and the like.

Description

technical field [0001] The present invention relates to air-jet looms, and more particularly to the weft insertion of air-jet looms when pneumatic tugging is used. Background technique [0002] At present, when the air-jet loom uses a hemming mechanism such as a pneumatic hemming device, when the reed moves to the vicinity of the cloth fell, it will interfere with some components in the hemming mechanism. In order to overcome the above-mentioned interference phenomenon, such as in order to avoid the reed teeth of the reed from colliding with the components such as the hemming mechanism, the existing technical means is: that is, at the position corresponding to some related components, the reed is disconnected for a certain distance, so that the steel reed When the reed moves to the vicinity of the cloth fell, the relevant components will be placed in the reed break, so the reed teeth of the reed will not collide with the relevant components. Although this technical means ca...

AI Technical Summary

Problems solved by technology

Although this technical means can better solve the above-mentioned interference phenomenon, it follows that after a certain distance is disconnected between the reeds, a corresponding interval area appears in the air flow channel, which brings problems such as poor weft insertion, Defects such as insufficient stability and reliability of machine operation, low weft insertion efficiency, etc.
