Abstract

The invention provides a sewing machine. The sewing machine comprises a needle bar, a first driving part in driving connection with the needle bar so as to drive the needle bar to rotate, a second driving part in driving connection with the needle bar so as to drive the needle bar to ascend and descend, and a take-up reel arranged above the needle bar. The take-up reel comprises a rotatably-arranged rotary arm, a threading hole for threading of a sewing thread is formed in the rotary arm, and the rotary arm is used for guiding the sewing thread entering the needle bar from the threading hole.Due to the fact that the needle bar can rotate, the circumferential angle of the needle bar can be adjusted in the sewing process so that the needle bar and a machine needle can be better matched withthe track, the sewing thread can be prevented from being wound on the machine needle or the needle bar, the sewing track can be kept consistent with the set pattern track, and therefore the sewing efficiency and the sewn pattern quality can be improved. Moreover, the sewing thread entering the needle bar can be guided through rotation of the rotary arm, and the rotating motion of the rotary arm cooperates with the up-and-down motion of the needle bar so that sewing can be smoothly carried out.

Description

technical field [0001] The present invention relates to the technical field of sewing equipment, in particular, to a sewing machine. Background technique [0002] With the increase of sewing demand, the sewing of fabrics has the characteristics of various patterns and flexibility, so the trajectory of the sewing thread on the fabric needs to be changed frequently. In this way, when sewing, the suture is easy to wrap around the needle or needle bar, which affects the sewing efficiency and quality. SUMMARY OF THE INVENTION [0003] The present invention provides a sewing machine to solve the problem in the prior art that the sewing thread is easily wound on the needle or the needle bar. [0004] In order to solve the above problems, the present invention provides a sewing machine, comprising: a needle bar; a first driving part, the first driving part is drivingly connected with the needle bar to drive the needle bar to rotate; a second driving part, the second driving part ...
