Looping mechanism of artificial lawn warp knitting machine

Abstract

A looping mechanism of an artificial lawn warp knitting machine comprises a yarn guide needle, a sinker and a knocking-over bar, wherein the yarn guide needle is fixed on each wool yarn guide bar; a sinker is fixed on a sinker bed; and the knocking-over bar is connected with a main shaft via a connection rod. The looping mechanism of the artificial warp knitting machine is characterized in that the knocking-over bar is provided with a plate body; the plate body is equipped with at least two baffle blocks arranged side by side; a groove is formed in the middle of each baffle block; all the grooves are the same; a needle slot is formed by adjacent baffle blocks; and a latch needle elevates in the needle slot. The looping mechanism is mainly applied to knitting artificial lawns; latch needle elevating stroke is added, so knitting product achieved has tight structure and is firm and durable.

Description

technical field [0001] The invention relates to a warp knitting machine, in particular to a loop forming mechanism of an artificial lawn warp knitting machine. Background technique [0002] Existing artificial turf warp knitting machines all rely on imports, which are not only expensive, but also have low production efficiency. After research, it was found that in the production process of the existing artificial turf warp knitting machine, due to the structural design defects of the knockout plate, the lifting stroke of the latch needle on the knockout plate is limited, so the final fabric has a loose structure. , is not durable. Secondly, the pinhole of the guide needle is not only small, but also has edges around the pinhole. Since the yarn of artificial turf is thicker than that of ordinary textiles, the yarn is often twisted when the guide needle cooperates with the latch needle to form a loop. The line is broken, thereby reducing production efficiency. Again, becaus...

[0002] The existing artificial turf warp knitting machines are all imported, which is not only expensive, but also has low production efficiency

After research, it was found that in the production process of the existing artificial turf warp knitting machine, due to the structural design defects of the knockout plate, the lifting stroke of the latch needle on the knockout plate is limited, so the final fabric has a loose structure. , not durable

Secondly, the pinhole of the guide needle is not only small, but also has edges around the pinhole. Since the yarn of artificial turf is thicker than that of ordinary textiles, the yarn is often twisted when the guide needle cooperates with the latch needle to form a loop. The wire breaks, which reduces the production efficiency

Thirdly, because the sinker bed is generally made of aluminum alloy, its strength is not very high, so it often deforms, and thus cannot normally complete the loop forming or stripping action
