Mounting structure of noodle thread disengaging mechanism of sewing machine

Abstract

The invention relates to a mounting structure of a noodle thread disengaging mechanism of a sewing machine, includes a frame of a sewing machine, A swing shuttle device is arrange on that frame, the position of the rotary shuttle corresponding to the machine base and the workbench is opened and a rotary shuttle port is arranged, a receiving groove is arranged on one side of the machine base rotaryshed, A lateral shaft hole are arranged on that two side wall of the receiving groove, the pivot shaft is arranged in the transverse shaft holes of the two side walls of the receiving groove 4, the axial direction of the pivot shaft is arranged parallel to the direction of the rotary shaft of the shuttle device, a pivot locking mechanism is arranged on the machine base or the work table, a connecting block is fixed on the pivot shaft, a detaching mechanism is fixed on the connecting block, and the working end of the detaching mechanism is matched with the shuttle device; The present inventionmounts the release mechanism on a rotating connecting block, the clearance between the disengaging mechanism and the rotary shuttle device can be adjusted by pivoting, On the one hand, the gap causedby the adjustment wear is too large, on the other hand, the corresponding gap can be adopted according to the yarns of different thicknesses and different materials, so that the stitch sewn out by the sewing machine worker is more beautiful and beautiful, and the invention makes the adjustment and replacement of the detachment mechanism more convenient and quick.

Description

technical field [0001] The invention relates to sewing machine technology, in particular to an installation structure of an upper thread detachment mechanism of a sewing machine. Background technique [0002] In the prior art, the disengagement mechanism, that is, the mechanism including parts such as the rotary hook positioning hook, is usually installed at the bottom of the sewing machine working platform, that is to say, when the disengagement mechanism needs to be installed or debugged, it is necessary to turn the sewing machine upside down. , but when the machine is large or heavy, and it is difficult to turn the machine over, the staff needs to lean over and drill into the bottom of the machine, which is very inconvenient, resulting in low efficiency in the installation or debugging of the detachment mechanism. [0003] For this reason someone installs the disengagement mechanism at the upper port of the rotary shuttle mouth, as the announcement number is CN 203741553 ...

AI Technical Summary

Problems solved by technology

[0004] The installation positions of the fixed knife, the rotary hook positioning hook and the thread splitter of this detachment mechanism are fixed. For example, after the fixed knife is worn for a period of time, the gap will increase, which will affect the thread trimming effect of the detachment mechanism. In some structures, only parts need to be replaced. Since the table top of the machine is very large, although the disengagement mechanism is set on the upper port of the rotary shed, it is not convenient to replace it on the workbench.

[0005] In addition, due to the fixed installation position of this structural detachment mechanism, the detachment mechanism needs to be customized for different models, and its versatility is poor, so it is not convenient for later management
