Technical Field
[0001] The utility model relates to the technical field of weft insertion structures of rapier looms, in particular to a weft insertion device for textile processing. Background Art
[0002] The rapier loom is the most widely used shuttleless loom. In addition to the characteristics of high speed, high degree of automation and high efficiency of shuttleless loom, its active weft insertion method has strong adaptability to variety and can adapt to the weft insertion of various types of yarns. The most important structure is the weft insertion device.
[0003] For example, the Chinese authorized patent with announcement number CN208829843U (a weft insertion structure for a high-speed rapier loom) comprises a base plate, a support plate fixedly connected to the top of the base plate, a bearing fixedly connected to one side of the support plate, the support plate rotatably connected to a cloth winding shaft via the bearing, a cloth winding roller sleeved on the surface of the cloth winding shaft, the support plate rotatably connected to a weft beating shaft via the bearing, a mounting plate sleeved on the surface of the weft beating shaft, a weft insertion plate fixedly connected to the top of the mounting plate. The weft insertion structure of this high-speed rapier loom positions the warp by a reed, drives the rapier pulley to rotate by a first reversing motor, thereby driving the rapier to slide through a limit box, causing the rapier to move in the weft insertion slot, so that the weft is pushed into the weft insertion slot through the guide plate, thereby achieving the effect of avoiding contact with the warp during the weft insertion process, achieving the goal of preventing the warp and weft from being entangled with each other, and being more convenient to use.
[0004] However, the weft insertion plate and the beating-up shaft of the existing rapier loom weft insertion structure are fixed by an embracing fixing buckle. Tools need to be used to remove the screws during disassembly and installation. Over time, it is easy for the weft insertion plate to rotate with the beating-up shaft, resulting in position displacement. Therefore, it does not meet the existing needs. In this regard, we propose a weft insertion device for textile processing. Utility Model Content
