Warp knitting machine mechanism capable of forming loops at high speed

Abstract

The invention relates to a warp knitting machine mechanism capable of forming loops at a high speed. The warp knitting machine mechanism comprises a swing arm fixing shaft, a penetrating swing shaft,a latch needle cam follower, knocking-over comb guide swing arm, a needle bed bracket, a knocking-over comb and a latch needle installed on a latch needle bed. The latch needle is fixed to the latch needle bed. The latch needle bed is fixed to the upper side of the needle bed bracket. A guide column of the needle bed bracket is installed in a guide column hole of the knocking-over comb guide swingarm. The knocking-over comb is fixed to the knocking-over comb guide swing arm. The knocking-over comb guide swing arm is fixed to the swing arm fixing shaft through the penetrating swing shaft. Theliner direction of the needle back of the latch needle, the central axis of the guide column of the needle bed bracket and the central axis of the latch needle cam follower are in parallel. The warp knitting machine mechanism is simple in structure and high in reliability, cost is saved, and the loop forming movement speed of a loop forming mechanism can be ensured when a warp knitting machine moves at a high speed.

Description

technical field [0001] The invention relates to a high-speed loop-forming warp knitting machine mechanism, which belongs to the field of textile machinery structures. Background technique [0002] The cam of the warp knitting machine is installed and fixed on the main shaft, which converts the rotation of the main shaft into linear motion, and the cam ejector rod is the part that realizes the linear motion. During the movement, the latch needles, guide needles, sinkers and knockout plates of the warp knitting machine cooperate with each other to form a knuckle movement. At present, the spindle speed of the warp knitting machine is relatively slow, and what restricts the increase of the spindle speed is that the loop forming parts do not cooperate smoothly, especially for the up and down movement of the latch needle, which has more speed restrictions. In the existing design, the back movement of the latch needle is limited. There is an included angle between the up and down ...

Problems solved by technology

At present, the spindle speed of the warp knitting machine is relatively slow, and what restricts the increase of the spindle speed is that the loop forming parts do not cooperate smoothly, especially for the up and down movement of the latch needle, which has more speed restrictions. In the existing design, the back movement of the latch needle is limited. There is an included angle between the up and down direction and the axis of the guide post of the needle bed bracket, resulting in frictional resistance when the latch needle cam ejector rod moves up and down, resulting in unnecessary force component friction, and the axis direction of the latch needle cam ejector rod is also in line with the guide post of the needle bed bracket. The axis of the column is not parallel, so that the up and down linear motion of the cam rotation conversion cannot be fully converted into the up and down motion of the latch needle, so that there is an angle between the two motion directions, which eventually slows down the running speed of the warp knitting machine

[0003] Defects of the existing mechanism: the back direction of the latch needle is not parallel to the axis of the guide column of the needle bed bracket; the axis of the guide column of the needle bed bracket is not parallel to the axis of the cam ejector rod of the latch needle; the running speed of the warp knitting machine is slow
