Technical Field

The invention belongs to the technical field of textile equipment, and particularly relates to a stocking machine sinker cover.

Background

Hosiery machine, the first knitting machine of the 1589 year imperial prunus invention, uses crochet knitting to form hosiery pieces, the knitting machine for producing hosiery. Hosiery machines can be classified according to the type of needle bed, the type of knitting needle and the number of cylinders (beds). For example, a flat hosiery machine, a circular hosiery machine and the like, the flat hosiery machine has low production efficiency, and the circular hosiery machine is widely used at present. In the process of weaving socks by the hosiery machine, when the socks need to have the knitting style of the terry, a plurality of needle tongues which are arranged in an annular shape above a needle cylinder generally move up and down along the longitudinal direction of the periphery of the needle cylinder and are matched with a sinker special for the terry to move transversely towards the center direction of the needle cylinder so as to carry out the action of staggered knitting, thereby finishing the terry knitting effect. The sinker cover is a common component on the hosiery machine and mainly comprises an annular shell and eyebrows, middle eyebrows and the like on the inner side of the shell, and a needle cylinder is arranged on the inner side of the sinker cover. The sinker is moved transversely along the contour of the eyebrow. Therefore, the sinker cover is an important component of the hosiery machine, and changing the angle of the sinker cover with respect to the knitting mechanism can be accomplished to vary a number of parameters of the hosiery produced. The existing traditional stocking machine sinker cover is fixed, the diameters of the produced stockings are equal up and down, and the stockings cannot be better attached to legs of a human body. Meanwhile, the eyebrows of the existing sinker cover are usually completely fixed on the sinker cover body and cannot rotate, the tightness of different parts of the socks cannot be controlled in the sock production process, and the application range is small.

In order to solve the problems of the prior art, people have long searched for and put forward various solutions. For example, chinese patent literature discloses a sinker cover [ application No.: 201620808928.7], mounted to a hosiery knitting machine base, comprising: the utility model provides a socks knitting machine, the utility model discloses a sinker cover body, mounting panel, first motor, gear and rack, the sinker cover body with the rack is installed respectively in socks knitting machine base, the mounting panel install in sinker cover body one side, first motor install in the mounting panel, gear connection first motor is by first motor control gear revolve, the gear with rack toothing.
