Abstract
Description
Technical Field
[0001] The utility model relates to the field of knitting equipment, in particular to a needle selection device for a knitting machine. Background Art
[0002] A knitting machine is a machine used to knit knitted fabrics (i.e. fabrics formed by the cooperation of needles and threads). According to the type of needles and the weaving method, knitting machines can be divided into many types, such as weft knitting machines and warp knitting machines. Weft knitting machines form fabrics by weaving yarns into coils along the transverse direction (weft direction) of the fabric, while warp knitting machines form fabrics by weaving yarns into coils along the longitudinal direction (warp direction) of the fabric. A knitting machine is usually composed of a frame, a needle bed, a yarn feeding device, a needle selector, a control system and other parts. Its working principle is to control the up and down movement of the needles and the delivery of the yarns so that the yarns form coils under the action of the needles, thereby forming fabrics. There are many types and brands of knitting machines, and their performance and quality directly affect the quality of the fabrics and the efficiency of production. The needle selector is one of the important accessories of the knitting machine, which is used to control the selection and movement of the knitting needles, thereby realizing the weaving and jacquard of the fabrics. The needle selector controls the movement of each knitting needle through a blade through an electromagnet or a stepper motor, so that it can be selected and moved up or down, thereby participating in or exiting the weaving process. However, during the up and down movement of the blade, the fabric fibers can easily enter the needle selector housing through the blade notch on the needle selector, causing blockage of the blade.
