Description

Yarn feeding mechanism of a hosiery machine

Technical Field

The utility model relates to the technical field of hosiery knitting machines, in particular to a yarn feeding mechanism for a hosiery knitting machine.

Background Art

The hosiery machine is the main equipment for producing socks. The common hosiery machine is mainly composed of a yarn feeding mechanism, a weaving mechanism, a needle selection mechanism, a control mechanism, a transmission mechanism and a pulling mechanism. Among them, the wire device in the yarn feeding mechanism is one of the important components of the production equipment.

The publication number CN215713728U discloses a fast yarn feeding mechanism for a drawing-in machine, including a mechanism body, an inspection door is provided on the front end outer surface of the mechanism body, a retractable yarn guide mechanism is provided in the middle of the mechanism body, a yarn feeding roller is provided at the upper end of the retractable yarn guide mechanism, and anti-displacement mechanisms are provided on both sides of the outer surfaces of the yarn feeding roller, and a control panel is provided at the upper end of the inspection door. The practical new fast yarn feeding mechanism for a drawing-in machine is provided with an anti-displacement mechanism and a retractable yarn guide mechanism, which can limit the two sides of the yarn material before the yarn feeding mechanism is used to prevent the yarn material from being displaced during rotation and affecting the rotation of the yarn feeding roller, which is beneficial to the use of the yarn feeding mechanism. The retractable yarn guide mechanism is provided to store the yarn guide roller after the yarn feeding mechanism is used, which can also reduce wrinkles generated during the yarn feeding process, which is beneficial to people's use and brings better prospects for use.
