AI Technical Summary
In traditional warp knitting machines, the large oscillation range of the comb bar and needle bed affects the speed of the machine.
The comb and needle bed oscillation mechanism is adopted. The main shaft drives the needle bed cam and the rear swing cam to control the synchronous oscillation of the comb and the needle bed, ensuring that the motion curves of the front and rear needle beds are consistent and that the comb and the needle bed move in opposite directions, thereby reducing the oscillation stroke of the comb.
The increased machine speed reduces yarn tension fluctuations, allowing the use of lower strength yarns and improving weaving efficiency.
