Presser foot device for a computerized flat knitting machine

Abstract

The invention discloses a presser foot device of a computerized flat knitting machine. The presser foot device comprises a presser foot base, a motor with double spindle noses, a motor bottom board, a presser foot transmission set and a brush transmission set, wherein the motor is fixedly arranged on the motor bottom board which is fastened on one side face of the presser foot base through a fastener, and the brush transmission set is arranged on the motor bottom board and connected with the second spindle nose of the motor; the presser foot transmission set is fixedly arranged on the other side face of the presser foot base and connected with the first spindle nose of the motor, the motor and the presser foot base are located in the middle, and the presser foot transmission set and the brush transmission set are located on the left side and the right side respectively. In the presser foot device of the computerized flat knitting machine, presser foot movement and brush movement are synchronous, irregular curves are used for guiding, the movement trail of a presser foot is not limited to a circumferential guide movement trail, the design of the movement trail is reasonable, the enough connection frame rod sway driving stroke is achieved, so that pressure is even and soft when the presser foot presses fabric, and enough space is provided for the installation positions of other parts.

Description

technical field [0001] The invention relates to a computerized flat knitting machine, in particular to a presser foot device for a computerized flat knitting machine. Background technique [0002] There are two kinds of pulling coils for computerized flat knitting machines, one is pulled by the traditional sinker, and the other is pulled by the presser foot; the sinker is arranged on both sides of each needle, and can only control each needle. The old loops and new yarns on the needle, so that the pull of the sinker sometimes causes needle paths, and the presser foot acts on several needles in a section, which controls the old loops on several needles in a section And the new yarn, the pulling method is concentrated pulling, and the presser foot can carry out shaping or three-dimensional weaving. The way that the existing presser foot device of computerized flat knitting machine adopts is that the guide and drive of the presser foot are generally driven by the double rocker...

AI Technical Summary

Problems solved by technology

The way that the existing presser foot device of computerized flat knitting machine adopts is that the guide and drive of the presser foot are generally driven by the double rocker mechanism that uses the connecting frame rod to shake. Guided movement, its movement space and trajectory are subject to certain restrictions

There is also a presser foot device that uses a gear transmission mechanism to drive the presser foot. Due to the complex structure of the gear transmission mechanism, the precision of parts manufacturing is high, thereby increasing the production cost of the machine.
