ZPF20-B28 Positive Yarn Feeder

The utility model relates to a yarn conveyer, which belongs to a yarn Conveyer for a knitting machine. 

The yarn carrier is directly connected with the stepper motor by a shaft. A transmission can also be arranged between the step motor and the yarn carrier.

When the driving pulse is fed in parallel to a set of rollers with the same size and structure with the same step motor of the same size, the yarn conveys the yarn of exactly the same length; and the yarn conveys in full synchronization.

 The utility model overcomes the disadvantage that the belt transmission elastic deformation causes the yarn conveying wheel to rotate unsynchronously, and is especially suitable for the knitting trolley.
