[Knowledge point] clothing technology: the general structure of warp knitting machine

Although there are many types of warp knitting machines, they usually consist of main institutions and auxiliary institutions.

1. Main institution

(1) The loop forming mechanism forms a warp-knitted stitch to form a warp knitted fabric. The main forming parts are knitting needles, sinkers and yarn guide needles. They are driven from the main shaft through their respective mechanisms and cooperate with each other in a circular motion.

(2) The warp mechanism supplies the yarn on the warp beam to the loop forming mechanism for knitting. There are usually two types of let-off mechanisms: one is an active type of warp-feeding mechanism that actively transports warp yarns by mechanical and electrical transmissions; the other is a passive-type warp-feeding mechanism that pulls warp beams by warp tension generated in weaving. .

(3) The bar traverse mechanism controls the bar with the guide needle fixed, and the mechanism of the yarn before and after the needle is made according to the law of the pattern. There are many types of bar traverse mechanisms due to the different embossing characteristics and abilities required for various warp knitting machines.

(4) A mechanism in which the take-up and take-up mechanism pulls the fabric from the loop forming area and rolls it into a cloth roll at a certain tension and speed.

( 5) The transmission mechanism takes the main shaft as the main body, and through various cams, eccentric connecting rods, worm worm gears, gears and other transmission parts, the parts of the machine are coordinated to work together.

2. Auxiliary institution

(1) The company that expands the variety of products and colors, the Piezo Jacquard mechanism, the terry mechanism, the gauze plate, the flower plate, the gap delivery and the multi-speed warp mechanism.

(2) The mechanism for making the machine easy to adjust and look after: the slow speed transmission device for adjusting the machine to ensure the slow rotation of the machine; the warp tension is too large, the yarn breaks or the defect occurs on the grey cloth, and the cloth rolls reach the specified requirements to make the machine Stopped self-stop devices, as well as instruments that check the speed and output of the machine.
