Embodiment 1

[0031] figure 1 figure 2 image 3 It is a structural diagram of a structure of multiple sewing actions controlled by one motor and a sewing machine of the present application. The structure of multiple sewing actions controlled by one motor specifically includes a motor 1, a presser foot lifting mechanism 2, a reverse stitching mechanism 3 and a thread trimming mechanism 5. The motor 1 includes an electromagnet 11 and / or a relay (the simultaneous solution of the electromagnet 11 of the present application uses a relay, and the effect is the same), an encoder 14, and the motor 1 has a front output shaft 12 and a rear output shaft 13. The rear output shaft 13 of 1 controls the presser foot lifting mechanism 2 and the reverse stitching mechanism 3, the rear output shaft 13 of the motor 1 passes through the electromagnet 11 and is fixed and fixed with the presser foot lifting cam 21, the transmission wheel 4 and the reverse stitching crank 31; The front output shaft 12 of the m...

Embodiment 2

[0041] This embodiment is basically the same as the first embodiment above, except that the presser foot lifter cam 21 of the presser foot lifter mechanism 2 is different.

[0042] exist Figure 10 Figure 11 Among them, the presser foot lifting cam 6 has a connecting rod groove 611, a rear shaft hole 614, a front low point 612 and a rear low point 613. The above presser foot lifting cam 6 is integrated with the electromagnet 11. Iron 11 pulls in and follows. The connecting rod slot 611 of the presser foot lifting cam 6 is open, and the presser foot lifting connecting rod 22 abutting against the connecting rod groove 611 can enter the presser foot lifting cam 6 laterally, and can leave the presser foot lifting cam 6 laterally. There is also a gap between the presser foot lifting cam 6 and the rear output shaft 13 to ensure that the presser foot cam 6 is displaced with the suction action of the electromagnet 11.

[0043] The above-mentioned presser foot lifting cam 6 has a c...

Abstract

The application provides a structure of controlling multiple sewing actions by a single motor and a sewing machine, and particularly relates to the technical field of sewing machine manufacturing. Thestructure comprises a motor, a presser foot lifting mechanism, a backstitch mechanism and a thread shearing mechanism; the motor comprises an electromagnet and a coding device; the motor is providedwith a front output shaft and a rear output shaft; the rear output shaft of the motor controls the presser foot lifting mechanism and the backstitch mechanism; the rear output shaft of the motor penetrates through the electromagnet and a presser foot lifting cam, a transmission wheel and a backstitch crank are fixedly installed on the rear output shaft; the front output shaft of the motor controlsthe thread shearing mechanism; and the front output shaft of the motor penetrates through the coding device and a thread cutting driving crank is fixedly installed on the front output shaft. According to the structure, the sewing actions including backstitch, presser foot lifting and thread shearing are realized by the motor; and the rear output shaft and the front output shaft of the motor are delicately used to control the actions of presser foot lifting, backstitch, and thread shearing, so the structure of the sewing machine is tight, and production cost of the sewing machine is greatly lowered.

Description

technical field [0001] The application consists of a structure and a sewing machine that controls multiple sewing actions by one motor, and specifically relates to the technical field of sewing machine manufacturing. Background technique [0002] Existing sewing machines basically control sewing actions such as reverse sewing, presser foot and thread trimming through electromagnets, and the realization of each function requires an electromagnet or a motor to control. At present, there is a function of controlling the presser foot, thread trimming and reverse stitching (needle pitch adjustment) through a stepping motor in the market. One of the stepping motors controls the thread trimming and lifting the presser foot through forward and reverse rotation, and the other motor independently Control reverse stitching (adjust stitch distance). This kind of sewing machine needs to be installed with two stepping motors to control the reverse sewing, presser foot, and thread trimmin...
