Abstract

The invention relates to a cloth-dragging wheel automatic control device and method for sewing machine auxiliary material delivery mechanism. The control principle of the invention is that: by using unilateral conductivity principle of diode, when the operator sends out instruction for reverse stitching or presser foot lifting, the cloth-dragging wheel electromagnetic valve also receives the signal, and makes the cloth-dragging wheel and the reverse stitching or presser foot air cylinder get the pressure and link operate without interference to each other; when material delivery by the cloth-dragging wheel is not needed, air source is switched by the self-locking switch and the cloth-dragging wheel is lifted. The invention solves the problem of thick material sewing machine cloth-dragging wheel automatic control, not only improves working efficiency, eases labor intensity of operator, lowers cost of the sewing machine, thus making operation by the operator free and easy.

Description

technical field [0001] The invention relates to an automatic control device and method for a mopping wheel of an auxiliary feeding mechanism of a sewing machine. Background technique [0002] There are two kinds of sewing machines using mop wheels, pneumatic control and manual control, but most of them are complicated in structure, inconvenient to operate and high in cost. When the sewing machine is doing reverse sewing, the mop wheel must be lifted to cancel the positive auxiliary feeding; when the sewing material is taken from the presser foot and the mop wheel after the sewing work is completed, the presser foot and the mop wheel must be lifted at the same time. material. The mopping wheel of the current sewing machine does not realize linkage with the reverse stitching action and the presser foot lifting action, and the operator's work intensity is high and the work efficiency is low. [0003] Therefore, how to make the mopping wheel, the presser foot and the reverse s...
