Needle and shuttle cooperation automatic adjustment mechanism and sewing machine

Abstract

The present invention provides a needle and shuttle cooperation automatic adjustment mechanism. The needle and shuttle cooperation automatic adjustment mechanism comprises a main motor, an upper shaft, a needle driving and thread take-up assembly with a needle rod and a frame needle, a lower shaft, a rotating shuttle, a needle rod height adjustment driving source, a rotating shuttle angle adjustment driving source, a rotating shuttle position adjustment driving source, a needle rod height adjustment mechanism connected between the needle rod height adjustment driving source and the needle rod,a rotating shuttle angle adjustment mechanism connected between the rotating shuttle angle adjustment driving source and the lower shaft, and a rotating shuttle position adjustment mechanism connected between the rotating shuttle position adjustment driving source and the lower shaft, wherein the needle rod height adjustment driving source drives the needle rod to move in the vertical direction through the needle rod height adjusting mechanism; the rotating shuttle angle adjustment driving source drives the lower shaft to rotate around the self axis through the rotating shuttle angle adjusting mechanism; and the rotating shuttle position adjustment driving source drives the lower shaft to move in the self axial direction through the rotating shuttle position adjusting mechanism. The height of the needle rod, the angle of the rotating shuttle and the left-right position of the rotating shuttle can be automatically adjusted, so that the debugging efficiency and the debugging accuracy ofneedle and shuttle cooperation are improved.

Description

technical field [0001] The invention relates to an automatic adjustment mechanism for needle shuttle cooperation. [0002] The present invention also relates to a sewing machine comprising the above-mentioned needle-shuttle cooperation automatic adjustment mechanism. Background technique [0003] In the actual use of current sewing machines, in order to adapt to different fabrics and machine needles, it is necessary to readjust the needle shuttle coordination, and the adjustment of the needle shuttle coordination includes the following content: 1. Adjust the height of the needle bar to adapt to different fabrics; 2. Adjust the angle of the rotary hook to adjust the morning and evening of thread hooking; 3. Adjust the left and right positions of the rotary hook on the axis of the lower shaft to adapt to needles of different thickness. But the adjustment of needle-shuttle cooperation is mainly manual adjustment at present. [0004] For some large garment factories, when face...

Problems solved by technology

However, at present, the adjustment of needle-shuttle cooperation is mainly manual adjustment.

[0004] For some large-scale garment factories, when faced with the switching of large quantities of garment fabrics and needle models, this manual adjustment of needle-shuttle coordination will consume a lot of time, the debugging efficiency is very low, and the debugging accuracy is also very high. Low

Especially for the future customized production mode, the contradiction between frequent needle-shuttle coordination switching and inefficient debugging will greatly affect efficiency and order delivery
