Description
Technical field
A kind of machine head of embroidery machine is the utility model is related to, specifically a kind of embroidery machine descended with line supplementary structure
Head.
Background technology
Lack effective nondominant hand through the lower string-passing structure that pin hole on embroidery needle is formed for embroider line in embroidery machine at present
Section, that is, embroider line lack good tension force retention property through later embroider line in other words through pin hole relative difficulty.The opposing party
Face embroidery machine industry has the reciprocal process of embroidery of hundreds of thousands time in the embroidered needle that shank connects on head during embroidery daily,
In order to ensure embroidery quality during this, the presser feet for an embroidered needle periphery of often embroidering just needs compress once.Since embroidered needle is
The needing of high-speed motion penetrates cloth cover, if presser feet forms extreme shock as shank high-speed motion obviously can hit cloth cover, and
It is not compress, so needing to be driven presser feet, that is to say, that presser feet should embroider it as shank is moved downward in embroidered needle
Before push down cloth cover, on the other hand cannot form impact again, existing technology mostly uses the technological means such as descending lifeline or spring
To realize, on the other hand the structure for presser feet is generally that a presser foot driving device drives a presser feet, the shape of presser feet
The periphery of embroidery needle is placed on for circular configuration, its compress trace of this circular presser foot is excessively obvious, the pressure of single presser feet
There is also the function that inhomogeneities drastically influence presser feet for power.
The content of the invention
The utility model provide it is a kind of it is simple in structure, descended good, the single head of line tension holding to be unworthy of presser feet
Transmission device, the machine head of embroidery machine descended with line supplementary structure of presser feet compress auxiliary embroidery.
A kind of machine head of embroidery machine descended with line supplementary structure, including machine head of embroidery machine, is connected with needle bar frame on head,
