Needle bar self-locking mechanism

Abstract

The invention belongs to the technical field of embroidery machines, in particular to a needle bar self-locking mechanism. The present invention comprises a guide rod vertically and fixedly arranged on the machine head housing, and a presser foot driver and a needle bar driver are axially movable on the guide rod, and the needle bar driver and the presser foot driver are vertically spaced apart from each other. set, and the needle bar driver is located above the presser foot driver, and the needle bar driver is connected to the needle bar through a clutch structure. The present invention establishes a linkage relationship between the presser foot driver and the needle bar driver, uses the position change of the presser foot driver to control the clutch structure between the needle bar driver and the needle bar, so as to realize the separation and connection of the needle bar; and when the needle bar driver After being separated from the needle bar, the needle bar lifting structure lifts the needle bar so as to lock the needle bar and prevent it from falling. Due to the arrangement of the axial detachment prevention structure, the needle bar will not break away from the needle bar frame.

Description

technical field [0001] The invention belongs to the technical field of embroidery machines and relates to a needle bar self-locking mechanism. Background technique [0002] Computerized embroidery machine is the most advanced embroidery machine in the contemporary era. It can achieve high-speed and high-efficiency traditional manual embroidery, and can also achieve "multi-level, multi-functional, uniform and perfect" that cannot be achieved by manual embroidery. Requirements, it is an electromechanical product that embodies a variety of high-tech. The needle bar mechanism is a very important part in the computerized embroidery machine. Generally, the needle bar driver is used to drive the needle bar to reciprocate up and down to perform needle drop. If it falls, the position of the needle bar cannot be locked, and it is difficult to realize the self-locking of the needle bar, and it is easy to fall off in the axial direction during the clutch switching process of the needle...

AI Technical Summary

Problems solved by technology

However, this solution still cannot lock the position of the needle bar during the working process, and it is difficult to realize the self-locking of the needle bar, and it is easy to fall off in the axial direction during the clutch switching process of the needle bar, causing the needle bar to fall and damage other mechanical parts. part
