Technical Field

The invention relates to a rapier loom.

Background

The existing air baffle plate of the square rapier of the double-layer rapier loom for producing the villus fabrics consists of three parts, namely an air jet plate, a red copper gasket, a bottom plate and the like, and is locked by dozens of socket head cap screws to form a whole. In order to ensure that the high-pressure air does not leak between the joint surfaces of all parts during the working process of the air baffle, the requirement on the machining precision of all parts is high, and the production cost is increased certainly.

Disclosure of Invention

The invention aims to overcome the defects of the technology and provide an integral structure mode. The function of inputting compressed air to spray high-speed and high-pressure airflow is integrated. The high-speed and high-pressure air flow sprayed out forms an air cushion layer in the gap between the air baffle plate and the square rapier, and the air cushion layer blocks the direct contact between the rapier and the air baffle plate, so that the high-speed reciprocating motion of the rapier becomes approximate resistance-free motion, the rapier can be protected from being abraded, the service life of the rapier can be prolonged, and the high temperature generated by friction force can be greatly reduced.

The method specifically comprises the following steps: the inside of the working face C close to the air baffle is parallel to the round blind hole, and after compressed air from a compressed air pipeline joint is received in the conical pipe threaded hole at the open end of the round blind hole, high-pressure air flow is ejected from the working face C at high speed even though the round blind hole is communicated with the air baffle through a plurality of through holes, an air cushion layer is generated in a gap between the air baffle and the rapier, the air baffle is prevented from directly contacting the rapier, and therefore the rapier is protected from being abraded.

Compared with the prior art, the invention has the advantages of simple and reasonable structure, low manufacturing cost and the like. Drawings
