Description

Needle bar assembly of embroidery machine

[ technical field ] A method for producing a semiconductor device

The utility model relates to an embroidery machine's technical field, especially an embroidery machine's needle bar assembly's technical field.

[ background of the invention ]

With the advancement of technology, computerized embroidery machines have become the main mechanical equipment in embroidery industry, and the most important part of the embroidery machines is the head part of the embroidery machine.

The working principle of the needle rod is that the needle rod is driven by an independent needle rod driving sliding block to reciprocate up and down, and the rotating shuttle is taken out. Because the needle bar moves directionally, the needle bar is of a cylindrical structure and is easy to rotate when reciprocating up and down. The needle bar guide structure of the traditional computer embroidery machine is composed of a plurality of guide grooves of a guide plate, the product cost is low, the rotating speed of a main shaft of the embroidery machine is greatly increased at present, the original guide groove mechanism cannot completely meet the performance requirements, the factors such as high abrasion and high thread breakage rate exist, and in order to improve the structural stability and the production efficiency, the original guide groove structure is abandoned and redesigned to be a guide column mechanism. The guide post has the structural advantages that: based on the guiding principle of the mechanism, the loading is light, the reciprocating motion is matched with the groove of the needle rod bottom dead center fixing piece, the contact surfaces of the mutually matched points are small, the friction coefficient is greatly reduced, and the production efficiency is greatly improved while the noise is reduced.
