The application of Riding servo on computerized flat knitting machine

I. Overview

China is the worldâ€™s largest sweater producer. Eighty percent of the worldâ€™s sweater products are produced in China. This means that China is also the largest consumer of computerized flat knitting machines. In the context of the continuous appreciation of the renminbi, rising labor costs, and increasing barriers to foreign trade, only by improving product quality and production efficiency can the manufacturers gain greater profits. Therefore, domestic demand for computer flat knitting machines will also increase.

Second, introduction of knitting machine

The flat knitting machine is a knitting flat knitting machine, which is generally referred to as a flat knitting machine. It is used for weaving sweaters and belongs to knitting machines. Nowadays knitting flat knitting machines are generally referred to as knitting machine flat knitting machines. The computer flat knitting machine is a kind of double needle sewing machine with needle-stitching and weaving knitting machines. It realizes a semi-automatic machine that weaves all computer-controlled automation. At present, flat knitting machines appearing on the domestic market are basically single and double headed, and there are few three-heads. The appearance of the computerized flat knitting machine has caused the flat knitting machine to move from one person to one person and one machine at a time. This not only drastically increases the production efficiency, but also greatly reduces the labor cost.

Third, the servo function A flat knitting machine is equipped with a set of spindle servo and a set of shaking bed servo (a set of servos includes a servo drive and a servo motor). The spindle servo makes the head reciprocating motion on the needle board through the belt motive head, and the spindle servo driver outputs the AB phase frequency division signal (also called the encoder signal) to make the system accurately read the needle number moved by the head and machine. The position of the head, through the number of read out of the head inside the machine to complete the various actions of the needle. The swaying servo serves as the drive to drive the entire needle plate to accurately position and move through the belt plus screw rod, so that the head needs to complete the directional change and re-enter the knitting area to complete the pattern movement to the right or left before the knitting area is completed. The number of stitches. The flat knitting machine completes the knitting of the entire pattern through the movement of the head and the needle plate and the related actions of the head.
Riding servo products can fully meet the various requirements of the flat knitting machine. In the course of operation, it is smooth and soft when the head rotates, and the body vibration is small; when the high-speed operation is performed, the head moves from the knitting area to the back and completes the reversing. There is only a few stitches of turning distance; the needle plate moves fast, and the head needs continuous operation without stopping Wait until the needle plate completes its movement and enter the weaving area. In short, the tripod DCS series servos have the advantages of fast response, precise positioning, short set-up time, and smooth operation, which can effectively improve the productivity and product quality of the flat knitting machine.
IV. Summary Nowadays, the tripod servo has been widely used in flat knitting machines and has a huge market share, which has been widely recognized by manufacturers and customers.
