Abstract

The invention provides a drive mechanism integrating trimming, thread slacking, routing and presser foot lifting and a sewing machine. The drive mechanism comprises a drive motor, a thread slacking shaft in transmission connection with the drive motor, a presser foot lifting transmission assembly connected with a presser foot lifting assembly, and a thread slacking transmission part connected with a thread slacking and routing assembly. The presser foot lifting transmission assembly comprises a presser foot lifting transmission rod and a presser foot lifting transmission part which are in sliding connection, the presser foot lifting transmission rod is fixedly connected with the thread slacking shaft, the presser foot lifting transmission part is connected with the presser foot lifting assembly, and the thread slacking transmission part is connected with the thread slacking shaft. One power source, namely the drive motor is adopted, so that the drive mechanism is simplified; meanwhile, the drive motor can control movement positions more accurately, routing and thread slacking actions and presser foot lifting and thread slacking actions are more accurate, and adjustment is more convenient.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a driving mechanism and a sewing machine integrating thread trimming, thread loosening, threading and presser foot lifting. Background technique [0002] After the existing interlock sewing machine stops the needle, when performing two series of actions: thread punching and thread loosening, thread trimming, presser foot lifting and thread loosening, and simple presser foot lifting and thread loosening, the forms adopted are all driven by a power source for thread punching and thread loosening Thread and thread trimming mechanism, another power source drives the presser foot lifting and thread loosening mechanism. Control the two independent power sources through electronic control to perform matching actions to realize the mutual combination of functional actions, so that after the sewing machine stops the needle, it can perform thread punching and thread loosening, thread trimming, presser f...
