Description

Zigzag sewing mechanism of computerized sewing machine

Technical Field

The utility model relates to the technical field of computer sewing machines, in particular to a zigzag sewing mechanism of a brain sewing machine.

Background

The bending machine is a special sewing machine of a sewing machine, is also called a zigzag sewing machine or a herringbone sewing machine, is used for the zigzag sewing with a certain elastic stitch, such as a bra, underwear and the like, and is commonly used for a two-point machine (304 lock stitch) and a three-point machine (308 lock stitch), and the electronic bending machine can set the bending stitch of straight line, 2 points, 3 points, 4 points, crescent shape, needle shape and the like on one sewing machine, thereby greatly improving the equipment activity rate.

The bending machine consists of a machine head, a machine seat, a transmission part and an accessory part. The handpiece is the main part of the tortuosity machine. The sewing machine consists of four mechanisms of needling, hooking, thread picking and feeding and auxiliary mechanisms of winding, pressing, tooth falling and the like, wherein the motions of the mechanisms are reasonably matched, and the sewing machine works circularly to stitch the sewing materials.

Currently, in the zigzag seam structure of the common electronic sewing machine in the market, a gear transmission structure is generally adopted to perform zigzag seam, and the conventional gear transmission structure has the following defects: on the one hand, the transmission chain of the gear transmission structure has more parts, complex assembly and high cost, and on the other hand, when the zigzag seam resets, the gear transmission can generate reset buffering, so that the reset is not timely, the reset precision is reduced, and the zigzag seam precision is reduced.

Disclosure of Invention

The utility model aims to solve the problems in the prior art, and provides the zigzag sewing mechanism of the computer sewing machine, wherein the cam and the reset limiting point are directly arranged on the motor shaft, the structure is simple, the transmission chain is reduced, and the reset precision can be improved.

The utility model solves the technical problems by adopting the technical scheme that: the zigzag sewing mechanism of the computer sewing machine comprises a stitch plate, wherein a cam is arranged on the front surface of the stitch plate, a motor is arranged on the back surface of the stitch plate, the output end of the motor is connected with the cam, a guide plate which is contacted with the cam and transmits stitches when the cam rotates is arranged on one side of the cam, the guide plate is arranged on the stitch plate, a self-positioning plate is arranged on the cam, and the cam is reset after the self-positioning plate is contacted with the guide plate.

As a further improvement of the present utility model, the motor is a stepping motor.

As a further improvement of the utility model, a transmission plate is connected to the guide plate.

The beneficial effects of the utility model are as follows: the zigzag sewing mechanism of the computer sewing machine has reasonable structure, the self-positioning plate forms the reset limiting point, the cam is directly connected with the motor, the cam and the reset limiting point are directly arranged on the motor shaft, the structure is simple, the structure which needs gear transmission in the past is changed, the transmission chain is reduced, the limit can be directly realized through the self-positioning plate, the reset error caused by the reset buffering of the traditional gear transmission structure is avoided, the reset precision can be improved, the use effect is good, and the popularization is facilitated.
