Abstract

The invention relates to a high-strength, wear-resistant and toughened rapier head for rapier looms, which is made of glass fiber reinforced polycarbonate thermoplastic resin composite material, and the glass fiber reinforced polycarbonate composite material is made of glass fiber and The polycarbonate thermoplastic resin is prepared by blending and granulating with a twin-screw extruder; then the obtained glass fiber reinforced polycarbonate thermoplastic resin composite material is injection molded by an injection molding machine to make a rapier loom tip; The glass fiber is pre-treated with special surface modification before being blended with polycarbonate to prepare a fiberglass with good wear resistance and fatigue resistance, high bending resistance, compression resistance, tensile strength, impact resistance, and heat resistance. Strong, long-lasting rapier points for rapier looms.

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 ...
