Introduce the history of warp knitting machine

Today, the national warp knitting machinery has reached 3000 units/year production speed, the development speed of the entire industry is beyond fantasy, not only the number of warp knitting machinery has increased, and the production level has also been greatly improved. The high-speed machine from the original speed of only 1000 revolutions, to the present 4400 revolutions, the maximum gate width from the original 90 inches to the present 268 inches, this 30 years or so, there have been tremendous changes. Together have to mention is the production level of domestic warp knitting machinery. The braiding mechanism includes a needle bed, a comb, a settling sheet bed and a press plate, which are generally driven by a CAM or eccentric connecting rod. Cams are often used in warp knitting machines with low speed and complex motion rules. Eccentric connecting rod is widely used in high speed warp knitting machine because of its smooth transmission, easy processing, low wear and noise during high speed operation. The main coil forming machine parts are knitting needle, yarn guide needle, settling sheet and pressing plate (for crochet machine). The knitting needles are arranged in a row on the bed and move with the bed. The guide needle is mounted on the strip to form the comb. The warp passes through the hole of the yarn guide needle, moves with the comb and winds on the needle, and weaves the fabric through the mutual movement of the knitting needle, settling sheet and other ring forming parts. Great progress has also been made in mechatronics and computer applications of warp knitting machines. Warp knitting machine manufacturers, for example, the EBA device with fixed length let-off has become the standard device of Tricot warp knitting machines, and the EBC device with 80 different let-off speeds in a complete tissue has also been widely used in the production of pattern tissues. The EL device of electronic comb movement and the SU device of computer controlled comb movement on lace machine have been widely used and have become the standard device in modern lace machines.
