Single-axis positive yarn feeder for computerized flat knitting machine

Abstract

The invention discloses a yarn feeder for a computerized flat knitting machine. The yarn feeder comprises a driving motor, a transmission case and a yarn driving roller, wherein the yarn driving roller is arranged on the transmission case and is connected with the output end of the driving motor through the transmission of a belt in the transmission case; the side face of the transmission case is provided with a yarn leading plate; the yarn leading plate is provided with a plurality of clamping groove yarn guides at equal intervals and is matched with the yarn driving roller to finish yarn feeding operation; and the surface of the yarn driving roller is uniformly coated with a titanium oxide layer, and is smooth and anti-static and fibers cannot be hung on the surface. The yarn feeder comprises the single-axis yarn driving roller which is matched with a yarn guiding part on one side to feed yarns led out of a tray on a yarn take-up frame into a head yarn nozzle of a knitting mechanism of the flat knitting machine, is the optimal device for multi-yarn feeding, and can effectively improve knitting efficiency and knitting quality.

Description

technical field [0001] The invention discloses a yarn feeder for a computerized flat knitting machine, which belongs to the manufacturing technical field of yarn feeding devices for a computerized flat knitting machine according to the International Patent Classification (IPC), and in particular relates to a single-axis active yarn feeder for a computerized flat knitting machine. Background technique [0002] Computerized flat knitting machine is a kind of weft knitting loom. Its cam device is like a set of plane cams. The stitches of the knitting needles can enter the grooves of the cams, and the cams can be moved to force the knitting needles to move up and down regularly in the needle grooves of the needle plate. Movement, and through the action of the needle hook and latch, the yarn can be knitted into a knitted fabric. In the yarn feeding or yarn feeding process, when the existing yarn feeder transmits the yarn, due to the friction between the yarn and the surface of th...

AI Technical Summary

Problems solved by technology

In the yarn feeding or yarn feeding process, when the existing yarn feeder transmits the yarn, due to the friction between the yarn and the surface of the yarn feeding roller, resistance is generated, especially in the case of multi-thread yarn feeding, the resistance Larger, affecting weaving efficiency and quality

[0003] In the prior art, as a yarn feeder, such as the yarn feeder structure disclosed in Chinese patent document CN2275102Y, it essentially serves as a yarn storage function. However, in actual use, the yarn feeding method of this yarn feeder is passive feeding. Yarn, it is difficult to control the tension of the yarn, and some yarns are easy to break
