Abstract
The utility model discloses a machine head needle bar guide plate which comprises a guide plate body, a plurality of limiting guide grooves I and a plurality of limiting guide grooves II, wherein the front side and the rear side of the guide plate body are inclined planes, the limiting guide grooves I which are arranged in rows and matched with the lower dead points of needle bars are arranged at the upper part of the guide plate body, and the limiting guide grooves II which are arranged in rows and matched with a presser foot lifting sleeve are arranged at the lower part of the guide plate body.
Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to the technical field of embroidery machines, in particular to the technical field of a machine head needle rod guide plate.
[ background of the utility model ]
At present, a needle bar frame structure on a machine head of an embroidery machine cannot limit and guide a presser foot on a needle bar. And thus the operation stability is poor.
[ Utility model ] content
The utility model aims to solve the problems in the prior art and provides a guide plate for a needle rod of a machine head, which can improve the operation stability and has a simple structure.
In order to achieve the purpose, the utility model provides a machine head needle bar guide plate which comprises a guide plate body, a plurality of limiting guide grooves I and a plurality of limiting guide grooves II, wherein the front side and the rear side of the guide plate body are inclined planes, the limiting guide grooves I which are arranged in rows and matched with the lower dead points of needle bars are arranged at the upper part of the guide plate body, and the limiting guide grooves II which are arranged in rows and matched with a presser foot lifting sleeve are arranged at the lower part of the guide plate body.
Preferably, the two inclined surfaces are inclined in opposite directions.
Preferably, the front side of the guide plate body is provided with a plurality of sinking grooves, and the rear ends of the sinking grooves are provided with fixing holes.
Preferably, the rear edge of the lower end of the guide plate body is chamfered to form a bevel edge.
Preferably, the needle bar device further comprises a needle bar frame, and a positioning groove matched with the lower end of the guide plate body is formed in the front end of the lower edge body of the needle bar frame.
The utility model has the beneficial effects that: the front side and the rear side of the guide plate body are inclined planes, the upper part of the guide plate body is provided with the limiting guide grooves I which are arranged in rows and matched with the bottom dead center of the needle rod, the lower part of the guide plate body is provided with the limiting guide grooves II which are arranged in rows and matched with the presser foot lifting sleeve, and when the avoidance connecting rod moves, the up-and-down swing amplitude causes collision on the guide plate body, so that the left-and-right swing of the bottom dead center of the needle rod is stabilized, and the left-and-right swing of the presser foot lifting sleeve is stabilized.
The features and advantages of the present invention will be described in detail by embodiments in conjunction with the accompanying drawings.
