Above-mentioned weft yarn arrestment mechanism, unsatisfactory to the weft yarn braking effect, especially all the more so when using the flat, plastic silk as weft yarn.Be mainly manifested in: beating up and cutting in the process of latitude, weft yarn can be by from extracting out between lower yarn clipping dish 16 and the upper yarn clipping dish 17, causes the phenomenons such as fabrics cloth cover out-of-flatness, burr be uneven in length.

Summary of the invention

Task of the present invention is to solve the technological deficiency of the weft yarn arrestment mechanism existence that plastic knitting cloth water jet loom uses in the prior art, and a kind of weft yarn arrestment mechanism is provided.

Its technical solution is:

A kind of weft yarn arrestment mechanism comprises cam, rotor, swing arm one, connecting rod, rubber spring, folder latitude wheel, base plate, swing arm two and can be pressed on the ceramic roller that the folder latitude is taken turns; Above-mentioned cam is fixed on the camshaft, rotor is connected to an end of swing arm one, the cylindrical of rotor abuts against on the outline of cam, swing arm one is installed on the frame by mandrel, and an end of connecting rod is connected with the other end of swing arm one by oscillating bearing one, and the other end is connected with an end of swing arm two by oscillating bearing two, rubber spring is nested with on connecting rod, swing arm two is installed on the base plate by mandrel, and the other end of swing arm two is connected with ceramic roller, and folder latitude wheel is connected on the base plate by wheel shaft.

Above-mentioned folder latitude wheel is comprised of metal wheel body and rubber ring, and rubber ring is nested with on the metal wheel body.

The present invention has following useful technique effect:

The present invention has good stable weft yarn braking effect, after weft yarn enters fell and is braked, is beating up and is cutting in the process of latitude, weft yarn can be taken turns tightly clamping by ceramic roller and folder latitude, weft yarn just can not extracted out between ceramic roller and folder latitude wheel like this, makes institute's woven fabric cloth cover smooth, and burr are neat.
