Embroidery machine high speed head assembly

Abstract

The invention discloses a high-speed hand piece assembly of an embroidery machine. The high-speed hand piece assembly of the embroidery machine comprises a machine shell and a driving shaft arranged on the machine shell, wherein a pressure foot sliding base is arranged on the driving shaft, a needle rod support is arranged on the front surface of the machine shell, a stepping motor is arranged on the machine shell, the pressure foot sliding base is connected with a connecting rod assembly and an independent lifting pressure foot, the stepping motor and the connecting rod assembly are transmitted by a middle transmission component, the pressure foot sliding base is driven to act on by the separate stepping motor in the head piece of each embroidery machine through the middle transmission component and the connecting rod assembly, the pressure foot sliding base drives the independent lifting pressure foot to act on, and a protective facial line clamp holder is arranged at the bottom part of the needle rod support. The independent lifting pressure foot is driven by the separate stepping motor, the shock of the pressure foot in cloth pressing operation is greatly reduced, the noise is reduced, the vibration of the hand piece is reduced, the friction of a pressure foot driving piece to a needle rod is reduced, and the load of the needle rod support is reduced, therefore, the needle can accurately embroider pattern, and the quality of the embroidery is improved.

Description

technical field [0001] The invention relates to an embroidery machine head. Background technique [0002] Such as figure 1 and figure 2 As shown, in the presser foot driving mechanism of the embroidery machine head in the prior art, a needle bar frame 5 is installed on the front of the casing 1, a row of needle bars 50 are arranged on the needle bar frame 5, and machine needles 501 are arranged at the bottom of the needle bars. Each needle bar 50 is equipped with a presser foot 502 to cooperate with the machine needle 501 . The specific driving method of the presser foot 502 is that a rotating main shaft 12 passing through a plurality of machine head casings 1 drives the presser foot in each machine head, and its movement principle is that the presser foot lifting cam 13 is installed and fixed on the rotating main shaft Above, the presser foot lifting cam 13 drives the presser foot connecting rod 14 through the rotation of the rotating main shaft, and the presser foot co...

AI Technical Summary

Problems solved by technology

[0006] 3. The operation of this structure needs to be driven by the rotating spindle, which will increase the load on the rotating spindle

[0007] In addition, since the presser foot is installed on the needle bar, the presser foot driver will generate greater friction on the needle bar, and the load on the needle bar frame is also heavy, which will affect the accuracy of embroidery and the quality of embroidery
