Problems solved by technology
[0005] It can be seen that the differential adjustment mechanism of the existing sewing machine usually relies on the chute slider mechanism to realize power transmission. In the actual work process, when the slider moves relative to the chute, there is severe friction between the slider and the chute. As a result, the slider is stuck in the chute, which seriously affects the stable operation of the differential adjustment mechanism. Therefore, the working reliability of the differential adjustment mechanism of the existing sewing machine is poor

The invention discloses a differential adjustment mechanism of a sewing machine. The differential adjustment mechanism comprises a differential retainer, an adjusting assembly and a differential shaftand also comprises a swing rod assembly, a swing driving rod and a differential slider assembly, wherein two ends of the swing rod assembly are respectively hinged between the differential retainer and the adjusting assembly; the swing driving rod is used for being connected with a cloth feeding mechanism; and the differential shaft can penetrate through the differential slider assembly, and thedifferential slider assembly is respectively hinged with one ends of the swing driving rod and the swing rod assembly away from the differential retainer. By applying the differential adjustment mechanism, because the differential slider assembly is respectively hinged with the swing rod assembly and the swing driving rod, a rotating pair is utilized for replacing a moving pair to solve the problems of unstable operation and the like due to the fact that a slider is stuck relative to a slide groove, and then, the working reliability of the differential adjustment mechanism provided by the invention is improved. The invention also discloses the sewing machine which has higher working efficiency.
Description
technical field [0001] The invention relates to the technical field of textile equipment, in particular to a differential adjustment mechanism of a sewing machine. The invention also relates to a sewing machine. Background technique [0002] The working principle of the existing sewing machine is that the needle bar drives the lead wire to pass through the looper with the winding thread on the bottom of the textile under the drive of the driving device to interweave the lead thread and the winding thread to realize sewing. In view of the special working principle of the existing sewing machine, it has the advantages of fast sewing speed, good sewing quality, and convenient operation. It is deeply favored by people and is widely used in clothing, household and other fields. [0003] Existing sewing machines usually include a needle bar stabbing and jumper mechanism, a differential adjustment mechanism, a cloth feeding mechanism, a looper thread hooking mechanism, and the lik...
