The classifications of sock machines

 Sock machine  classification Sock machine can be classified according to needle bed form, needle type and number of syringes (beds). The flat sock machine has a high machine number, and produces flat sock pieces that change the width of each part according to the shape of the feet and legs, and then stitch them into sewn socks. The round sock machine has a wide range of gauges, and the production of tubular socks blank is by changing the coil size of each section, or using elastic yarn, or weaving forming socks, sock heels and other methods to adapt to the shape of the foot. The toe of the tubular sock blank is closed into seamless socks. The  flat sock machine  has a low production efficiency, and later the round sock machine is widely used. Sock machine structure round sock machine is mainly composed of yarn feeding mechanism, weaving mechanism, needle selection mechanism, control mechanism, transmission mechanism, density adjustment mechanism and pulling mechanism. Some sock machines also have a starting and folding mechanism. The  flat sock machine  also has a circle transfer mechanism.

The function of the yarn feeding mechanism

The function of the yarn feeding mechanism is to lead the yarn out of the package and send it into the weaving area, there are two types: passive and positive. Passive yarn feeding is to use tension to lead the yarn out of the package, although there is a tension and tension compensation device to control its tension and the amount of delivery, but the yarn tension difference is still large. Active yarn feeding uses a special device to feed the yarn into the weaving zone at a constant linear speed, and the difference in yarn tension is small.

The function of the weaving mechanism

The function of the weaving mechanism is to weave the yarn into tubular sock blanks or flat sock sheets through the work of the coil machine. The weaving machine of round sock machine includes knitting needle, sinking sheet, yarn guide and triangle. Flat sock machines include knitting needles, yarn bending sheets, yarn splitting sheets, de-looping sheets, yarn guides and tablets. The needle of the round sock machine is arranged on the syringe barrel, and the yarn guide is fixed around the syringe barrel to feed the yarn into the weaving area. There are several incoming lines called several channels, generally there are 1~12 channels, the more the number of roads, the higher the productivity. When the syringe rotates, the latch needle is moved up and down by the action of the triangle, and is woven by the yarn guide pad. When knitting the heel and head of the socks, the needle picker and needle picker collect and place the needle participating in the weaving to form a bag shape. The needles of the flat sock 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 pad the yarn, while weaving is carried out by a combination of bent sheets, yarn splitting sheets and decoiled sheets.

The function of the control mechanism

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 syringe and rotation speed and steering, as well as the length of the sock. The function of the transmission mechanism is to make each mechanism move according to a predetermined regularity. The syringe of the round sock machine not only rotates in one direction, but also rotates in both directions when knitting the heel and head of the socks. The function of the needle selection mechanism is to arrange the pre-designed pattern in the needle selection device in turn according to the requirements, and make the knitting needle weave according to a certain procedure by passing the mechanism. The function of the density adjustment mechanism is to adjust the density of each part when knitting socks, which is carried out by changing the relative position of the needle and the settler to adjust the bending depth. The function of the pulling mechanism is to lead the formed coil out of the braid area with the help of heavy hammers, rollers, airflow, etc. during the weaving process.

The function of the starting and folding mechanism

The function of the starting and folding mechanism is to start the head when the socks begin to weave a wireless circle, and when the socks are woven to a certain length, the single-layer socks are folded in half into a double layer, so that the socks have good elasticity, do not produce curl, generally with the sock hook to complete. The main function of the ring transfer mechanism is to move the coil from one needle to another with the ring transfer mechanism to change the weaving width of the sock and make it shaped.
