Problems solved by technology

This structure makes the machine head higher, resulting in a complex structure of the template machine, and there is a defect that it is troublesome to adjust the synchronous relationship between the thread take-up assembly and the stabbing cloth assembly (that is, the synchronous relationship between the thread take-up lever and the needle bar)

Abstract

The invention relates to the technical field of sewers, in particular to a needle bar rotating type template machine. The needle bar rotating type template machine comprises a needle bar, wherein an upper shaft, a thread picking assembly and a cloth needling assembly are arranged on one side of the needle bar, the thread picking assembly and the cloth needling assembly are both arranged on the upper shaft, the upper shaft is driven by a first power part to rotate and drives the thread picking assembly and the cloth needling assembly to synchronously execute the thread picking action and the cloth needling action. The thread picking assembly and the cloth needling assembly are arranged on the same upper shaft and both located on one side of the needle bar, so that the height of a machine heat is not required to be increased because of the thread picking assembly, and the needle bar rotating type template machine has the advantage of being simple in structure. Besides, the thread pickingassembly and the cloth needling assembly perform coaxial output, so that the stable and good synchronous relation can be kept between the thread picking assembly and the cloth needling assembly, theproblem of trouble in adjustment of the synchronous relation between the thread picking assembly and the cloth needling assembly is solved, and the reliability and stability of action of the assemblies are better.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a needle bar rotary template machine. Background technique [0002] The needle bar rotary template machine is a template machine in which the needle bar can rotate during the sewing process. It is divided into two structures. One is the non-360° infinite rotation structure of the needle bar. It will entangle the needle to a certain extent, affecting the appearance of the stitches and normal sewing stability; the other is the structure that the needle bar can rotate 360° infinitely during the sewing process, which can realize continuous rotary sewing, and the suture will not be entangled with the needle. For example, the publication number is CN109554846A, which discloses a sewing machine needle bar and thread take-up mechanism capable of infinite rotation. [0003] In the existing needle bar rotary template machine, a motor drives the thread take-up assembly to move the ...
