Independent presser foot control mechanism of embroidery machine

Abstract

The invention provides an independent presser foot control mechanism of an embroidery machine, aiming at solving the existing technical problem. The independent presser foot control mechanism comprises a machine head seat, wherein a driving mechanism is arranged on the machine head seat and connected with a presser foot driving seat through a connecting rod transmission structure; the presser foot driving seat movably sleeves a presser foot driving rod which is fixedly connected with the machine head seat; one end of the presser foot driving seat is connected with a presser foot needle bar which can synchronously move along the presser foot driving seat when the presser foot driving seat moves up and down along the axial direction of the presser foot driving rod; a presser foot is connected onto the presser foot needle bar; and a needle bar assembly which is movably arranged relative to the presser foot driving seat and does not interfere the presser foot driving seat when the presser foot driving seat moves up and down is connected to the peripheral outer side of the presser foot driving seat through a rod body positioning structure. The independent presser foot control mechanism disclosed by the invention has the advantages of adjustable initial height of the presser foot, low spindle load and the like.

Description

technical field [0001] The invention belongs to the technical field of embroidery machines, and relates to an independent presser foot control mechanism of the embroidery machine. Background technique [0002] When the existing embroidery machine is in use, the driving wheel drives the needle bar to run up and down, and the presser foot runs along with the needle bar and the presser foot through the connecting rod arranged on the needle bar or the needle bar driving wheel or directly driven by the needle bar. The presser feet in the machine head are directly installed on the needle bar of the needle bar frame of the machine head seat, and a retaining ring is set on the needle bar. The retaining ring is pressed on the presser foot by a spring. Due to the existence of the spring, the cloth is not affected during work. The impact force on the surface is relatively large, which affects the quality of the finished product, and the pressure of the presser foot depends on the press...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned solution has improved some problems of the prior art to a certain extent, but the solution still has at least the following defects: the initial stroke of the presser foot is difficult to be adjusted independently, the applicability to different fabrics is poor, the impact of the presser foot on the fabric is strong, Loud working noise and low working efficiency
