Abstract

The utility model relates to a zigzag sewing machine, particularly a stitch trace zigzag sewing machine in a high-speed single needle locking type, which comprises a machine head, a machine frame, a needle board, a pressing foot device, a material feeding tooth plate, a driving mechanism and a power mechanism. The utility model is characterized in that the needle board is longitudinally provided with a convex rib with a triangular section and material feeding teeth and the inclination of the pressing connection slope of pressing feet is matched with the slope of the convex rib. The utility model is used for the hiding sewing process of a hand flap pocket and overcomes the defect that the existing machine can only be used for sewing a back collar.

Description

Zigzag sewing machine

The utility model relates to a kind of Zigzag sewing machine, especially high speed single needle lock-type chain stitch Zigzag sewing machine.

Common Zigzag sewing machine is because stitching is obvious, and what can only be used for leading behind the western-style clothes makes singlely, the hand pattern bag stowing manufacture craft that can not be used to have relatively high expectations, and the requirement of the western-style clothes manufacture craft that is not suitable for improving has day by day limited the scope of application of machine.

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of Zigzag sewing machine that is applicable to hand pattern bag stowing manufacture craft is provided.

For achieving the above object, solution of the present utility model is: curve crease Sewing machines still comprises headstock, needle plate, feeding dental lamina, presser feet, frame and transmission and actuating unit, vertically being provided with a cross section on needle plate is leg-of-mutton convex tendon, the convex tendon center is provided with pin hole, both sides are provided with the feeding alveolus, the feeding dental lamina is provided with the feeding tooth that gradient cooperates with the convex tendon inclined-plane, and presser feet below crimping face cooperates with inclined-plane, convex tendon both sides.

Owing to adopted above scheme, when making the hand pattern bag crease, crease and horizontal plane have a certain degree, and stitch of making and rip out stitches are very close, and therefore ironing back rip out stitches is very not obvious, reach the manual aesthetic measure of making, and stitch are more neat.

The utility model is further elaborated and provides embodiment below in conjunction with accompanying drawing.
