Description
Technical field
The utility model relates to Sewing machines field, is specifically related to a kind of Sewing machines utilizing driving stepper motor needle gage governor motion.
Background technology
The needle gage governor motion of current Sewing machines is generally regulated by two kinds of modes, and one utilizes manual rotation needle gage dial plate metering needle distance, this kind of regulative mode not only poor accuracy, and needle gage is opened large rear unstable, and operating efficiency is lower; Another kind realizes by backstitching electromagnet or manually backstitching spanner, and the needle tracking repeatability of this kind of mode is poor, and quality is lower.The process of making of above-mentioned two kinds of modes can not realize auto-changing, the close joint of needle gage automatically and backstitch function, can not meet higher stitching process requirement.
Summary of the invention
The utility model is a kind of Sewing machines utilizing driving stepper motor needle gage governor motion, overcome the existing needle gage governor motion that realizes can not realize auto-changing, close joint in the process mid-cut of making, backstitch function, and solve and backstitch needle tracking and to overlap the problem of poor and big needle distance instability.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of Sewing machines utilizing driving stepper motor needle gage governor motion, comprise head and cloth feeding mechanism, the bottom of described head is provided with stepper motor and falls along seam driving shaft, the suitable seam driving shaft that falls is connected with cloth feeding mechanism, have driving shaft in stepper motor, described stepper motor and suitable seam between driving shaft of falling are provided with change gear mechanism; Described change gear mechanism comprises driving gear and the driven gear of external toothing, and described driving gear is positioned at the end of driving shaft, and driven gear is positioned at down along seam driveshaft end.
Described stepper motor is arranged on head by stepper motor mount pad, described stepper motor (3) be stepper motor with absolute position encoder.
Compared with prior art, the utility model has the advantages that:
1, driver drives stepper motor of the present utility model turns an angle, drive along seam drive shaft turns by gear, change cloth feeding mechanism cloth feed amount and cloth feeding direction, realize automatic needle gage and regulate, make the conversion of process mid-cut, close joint, backstitch function.
2, the utility model can carry out the adjustment of accurate needle gage automatically, meet higher stitching process requirement, and automatic pouring suture needle mark registration is high.
