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 comprises a frame mechanism and an electronic weft feeder. The electronic weft feeder comprises a weft table assembly, weft drums, a vertical transmission shaft, a weft feeding motor and an electromagnetic brake assembly. The frame mechanism comprises a left wall plate, a right wall plate, a middle wall plate, and first and second spacer groups; the left wall plate is connected with the middle wall plate through the first spacer group; and the right wall plate is connected with the middle wall plate through the second spacer group. The winding mechanism comprises a water squeezing roller; the water squeezing roller includes a rubber roller inner cylinder, and a kiss-coating layer disposed at the outer cylinder wall of the rubber roller inner cylinder; each of two ends of the rubber roller inner cylinder is provided with an axle head; and each axle head is fixed on the inner cylinder wall of the rubber roller inner cylinder through an axle head internal support disc and an axle head external support disc. 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 supply part includes a weft yarn cylinder and a weft yarn table assembly. The weft ...

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.
