Automatic adjustment mechanism for needle-shuttle cooperation and sewing machine

Abstract

The invention provides an automatic adjustment mechanism for needle-shuttle cooperation. The automatic adjustment mechanism comprises a main motor, an upper shaft, a cloth needling and thread take-upcomponent provided with a needle bar, a lower shaft, a rotating shuttle, a needle bar height adjustment drive source, a rotating shuttle angle adjustment drive source, a rotating shuttle position adjustment drive source, a needle bar height adjustment mechanism, a rotating shuttle angle adjustment mechanism and a rotating shuttle position adjustment mechanism, wherein the rotating shuttle angle adjustment mechanism comprises a rotary arm, an angle adjustment output shaft and a first transmission component connected between the rotary arm and the angle adjustment output shaft; the needle bar height adjustment drive source drives the needle bar to move in a vertical direction through the needle bar height adjustment mechanism; the rotating shuttle angle adjustment drive source sequentially drives the lower shaft to rotate around the own axis through the rotary arm, the first transmission component, the angle adjustment output shaft and a second transmission component; and the rotating shuttle position adjustment drive source drives the lower shaft to move in the own axial direction through the rotating shuttle position adjustment mechanism. According to the automatic adjustment mechanism, the height of the needle bar, the angle of the rotating shuttle and the left and right positions of the rotating shuttle can be automatically adjusted, and the automatic adjustment of the needle-shuttle cooperation is realized.

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
