Plastic knitting machine

Abstract

The invention discloses a plastic knitting machine, which is characterized by including a shedding mechanism, a water jet weft insertion mechanism, a beating-up mechanism, a let-off mechanism, a winding mechanism and an auxiliary mechanism. The auxiliary mechanism includes a frame mechanism and an electronic weft cutter. The electronic weft cutter comprises a main controller, a current relay, a current transformer, a first copper terminal, a second copper terminal and a resistance wire for thermally cutting off a weft yarn; the main controller is connected with the current relay; the current relay is connected with the current transformer; the current transformer is connected with the first copper terminal and the second copper terminal; and the resistance wire has one end connected with the first copper terminal and the other end connected with the second copper terminal. The frame mechanism includes a left wall plate, a right wall plate and spacers; a middle wall plate is arranged between the left and the right wall plate; the left wall plate is connected with the middle wall plate through a first spacer group; and the right wall plate is connected with the middle wall plate through a second spacer group. The plastic knitting machine is not only suitable for knitting wide and heavy fabrics, but also in favor of further improvement and guarantee on the quality of plastic fabrics.

Description

technical field [0001] The invention relates to a plastic weaving cloth water jet loom, in particular to a flat weaving plastic weaving machine. Background technique [0002] Existing flat weaving plastic knitting machines include opening mechanism, water jet weft insertion mechanism, weft beating mechanism, warp let-off mechanism, take-up mechanism and other auxiliary mechanisms. Other auxiliary mechanisms may include weft yarn supply part, length measuring device, storage Weft device, weft yarn cutter device, hemming device and warp breaking automatic stop device, etc. Its main working principle is roughly: the shedding mechanism drives the heald frame to move up and down, and the plastic thread used as warp yarn is used to form the shed. The mechanism drives the reed to drive the weft yarn entering the shed into the weaving fell to weave plastic woven cloth. The above-mentioned weft yarn cutter device generally adopts a fixed blade, which cuts the weft yarn when beating...

AI Technical Summary

Problems solved by technology

The above-mentioned frame mechanism has the following problems when weaving heavy fabrics, especially wide fabrics: ① the width of the fabric suitable for weaving is relatively narrow, generally below 3.5 meters; ② the weight of the fabric suitable for weaving is small, generally around Below 130g / m2

It has been verified by production practice that the bending resistance of the structure is not good. After the glue is applied, the outer surface does not have a mid-height or the entire outer surface has a mid-height, and the water squeezing effect is not ideal.
