What Are The Categories Of Hosiery Machines?
Hosiery machines can be classified according to the type of needle bed, the type of knitting needle and the number of needle barrels (beds). Hosiery machine number is higher, production according to the shape of feet and legs to change the width of each section of flat socks, after sewing into sewed socks. Hosiery machine has a wide range of machine numbers. The production of tubular stockings depends on changing the coil size of each section, or using elastic yarn, or knitting socks, heels and other methods to adapt to foot shape. The socks of tubular stockings are sealed into seamless socks. The production efficiency of flat sock machine is low, and round sock machine is widely used at present. Hosiery machine structure hosiery machine mainly consists of yarn feeding mechanism, knitting mechanism, needle selection mechanism, control mechanism, transmission mechanism, density adjustment mechanism and traction mechanism. Some hosiery machines also have opening and folding mechanisms. Hosiery machine has a ring-shifting mechanism.
The function of the yarn feeding mechanism is to draw the yarn from the cylinder and feed it into the knitting area. There are two kinds of yarn feeding mechanism: negative and positive. Negative yarn feeding is to draw yarn from the cylinder by tension. Although tension and tension compensating device control its tension and delivery, yarn tension difference is still large. Active yarn feeding is equipped with special devices to make the yarn enter the knitting area at a constant linear speed, and the yarn tension difference is small.
The function of the knitting mechanism is to knit yarn into tubular stockings or flat socks through the work of looping parts. The knitting parts of hosiery machine include knitting needle, sinker, yarn guide and triangle, etc. Hosiery machines include knitting needles, yarn bending, yarn dividing, looping, guide and pressing, etc. The knitting needle of the hosiery machine is arranged on the needle barrel, and the yarn guide is fixed around the needle barrel to send the yarn into the knitting area. Several routes are called several routes. Generally, there are 1 to 12 routes. The more routes, the higher productivity. When the needle barrel rotates, the tongue needle moves up and down by the action of triangle and is knitted by the guide yarn cushion. When knitting sock heel and sock head, needle pick and pinch are used to collect and release needles to form a bag shape. The knitting needles of the hosiery machine are fixed on the needle bed in a row and move with the needle bed. The yarn guide moves along the needle bed to cushion the yarn. At the same time, the guide is knitted by the combination of the bending yarn, the dividing yarn and the looping yarn.
The function of the control mechanism is to control the entry or exit of the relevant parts in the process of knitting a sock, and to control the needle barrel, speed and steering, as well as the length of the socks. The function of the transmission mechanism is to make the mechanism move according to the predetermined law. The needle barrel of the hosiery machine not only rotates in one direction, but also rotates in two directions when knitting the heel and sock head. The function of the needle selection mechanism is to arrange the pre-designed patterns in the needle selection device in turn according to the requirements, and to make the knitting needles knit according to a certain procedure by transferring the machine parts. The function of density adjusting mechanism is to adjust the density of each section in knitting socks by changing the relative position of knitting needle and sinker to adjust the yarn bending depth. The function of the pulling mechanism is to draw the formed coils out of the braiding area by means of hammer, roller and air flow during the braiding process.
The function of the opening and folding mechanism is to start the socks when they begin to knit a wireless loop, and when the socks are knitted to a certain length, fold the single socks into two layers, so that the socks have good elasticity and do not produce curling edges. Generally, the socks are finished with sock hooks. The main function of the loop-shifting mechanism is to change the knitting width of socks by shifting the coil from one needle to another with a loop-shifting device.
