Abstract

The invention relates to a high-strength wear-resistant toughened rapier head for a rapier loom. The rapier head is prepared from a glass-fiber-reinforced polycarbonate thermoplastic resin composite material. The glass-fiber-reinforced polycarbonate thermoplastic resin composite material is prepared by blending and granulating glass fibers and a polycarbonate thermoplastic resin by a double screw extruder; and the prepared glass-fiber-reinforced polycarbonate thermoplastic resin composite material is subjected to injection molding by an injection molding machine to prepare the rapier head for the rapier loom. The glass fibers are subjected to surface modification treatment before being blended with the polycarbonate, so that the rapier head for the rapier loom has the advantages of favorable wear resistance, favorable fatigue resistance, bending resistance, compression resistance, tensile resistance, high shock strength, high heat resistance and long service life.

Description

technical field [0001] The invention relates to a textile machinery component, in particular to a high-strength, wear-resistant and toughened rapier head for a rapier loom. Background technique [0002] With the development of new textile machinery in our country, the quality requirements for parts in textile machinery are getting higher and higher. These parts must not only have good physical and mechanical properties, but also have excellent processability and low production efficiency. cost. [0003] At present, among all kinds of new looms used in the textile industry, the rapier loom has simple structure and wide adaptability, and has been widely used. On the existing rapier looms, since the front gripper of the rapier head adopts the design of the back-shaped hook and the elastic rod to passively clamp the weft yarn, the rapier head back-shaped hook at high speed retreats when the rapier loom is weaving. The hook hooks the weft yarn with a certain tension and clamps ...
