Embroidery machine head and embroidery machine

Abstract

The invention discloses an embroidery machine head and an embroidery machine. The embroidery machine head comprises a base frame, a control panel, an embroidery device and a stiletto device. The stiletto device comprises a stiletto cutter bar and a stiletto cutter; a needle bar and the stiletto cutter bar are driven by an independent embroidery driving system and a stiletto driving system respectively; the stiletto driving system comprises a stiletto motor and a stiletto transmission mechanism; the stiletto transmission mechanism comprises a first belt pulley, a second belt pulley, a stilettodriving shaft and a connecting rod assembly; The connecting rod assembly comprises a driving rod sleeved on the stiletto driving shaft, a first connecting rod connected to the driving rod, a three-eyeconnecting rod connected to the first connecting rod, and a second connecting rod connected with the three-eye connecting rod; The second connecting rod is connected with the stiletto cutter rod to drive the stiletto cutter to move up and down, so that the rotation angle of the stiletto motor can be controlled by the control panel to change the depth of the stiletto, adapt to the fabric of different thicknesses, enable the broader adaptability of the embroidery machine head; at the same time, the rotation speed of the stiletto motor can be improved to enhance the efficiency of hole engraving.

Description

technical field [0001] The invention relates to the technical field of embroidery machines, in particular to an embroidery machine head and an embroidery machine. Background technique [0002] At present, for the embroidery machine industry, with the improvement of product performance and the aesthetic requirements of fabrics, it is becoming more and more frequent to realize carving and embroidery on the same piece of fabric. Existing embroidery machine heads with both engraving and embroidery functions usually implement the two functions by setting up a motor to drive the main shaft to rotate, thereby realizing embroidery and engraving. The depth can be adjusted, that is, it can only adapt to one thickness of fabric, and the adaptability is single, and because the embroidery and the engraving are both driven by the same spindle, that is, the embroidery speed and the engraving speed are consistent, in order to ensure the normal operation of the embroidery, the motor cannot b...

Problems solved by technology

Existing embroidery machine heads with both the engraving function and the embroidery function generally implement the two functions by setting up a motor to drive the main shaft to rotate, thereby realizing embroidery and engraving. The depth can be adjusted, that is, it can only adapt to one thickness of fabric, and the adaptability is single, and because the embroidery and the engraving are both driven by the same spindle, that is, the embroidery speed and the engraving speed are consistent, in order to ensure the normal operation of the embroidery, the motor cannot be used. and spindle speed increase too much, which reduces the engraving efficiency
