Double-needle bi-color embroidery machine head with stiletto function

Abstract

The invention discloses a two-needle two-color embroidery machine head with the function of carving holes, which comprises the embroidery machine head, a needle bar frame which can move left and right is connected to the machine head, and more than two needle bars are installed on the needle bar frame and a thread take-up bar, the needle bar is driven by a needle bar driver, the thread take-up bar is driven by a thread take-up shaft, the needle bar driver includes a first needle bar driver and a second needle bar driver, the first needle bar driver inserts and drives the first needle At the same time, the second needle bar driver is inserted to drive the second needle bar. After the needle bar frame moves, the first needle bar driver is inserted to drive the third needle bar, and the second needle bar driver is inserted to drive the fourth needle bar. In the present invention, the first needle bar driver and the second needle bar driver cooperate with two sets of double-needle needle bars respectively to realize two sets of double-needle embroidery functions, thereby greatly improving embroidery efficiency.

Description

technical field [0001] The invention relates to an embroidery machine head, in particular to a two-needle two-color embroidery machine head with the function of carving holes. Background technique [0002] At present, for the embroidery machine head, the color of the pattern in the embroidery process is relatively single, especially on the high-speed double-needle embroidery machine head, the color is basically only one color, because the double-needle embroidery at the same time generally does not affect the color. The color of the embroidery thread on these two needles is different, they are all the same, and it is not meaningful to change the color. It cannot be realized, and currently only one group of double-needle embroidery has severely limited the pattern and color samples of double-needle embroidery. How to increase the color samples of double-needle embroidery has always been the research object of those skilled in the art. [0003] On the other hand, the thread t...

Problems solved by technology

[0002] At present, for the embroidery machine head, the color of the pattern in the embroidery process is relatively single, especially on the high-speed double-needle embroidery machine head, the color is basically only one color, because the double-needle embroidery at the same time generally does not affect the color. The color of the embroidery thread on these two needles is different, they are all the same, and it is not meaningful to change the color. Unable to achieve, currently can only stay on a group of double-needle embroidery, which severely limits the pattern and color samples of double-needle embroidery. How to increase the color samples of double-needle embroidery has always been the research object of those skilled in the art

[0003] On the other hand, the thread take-up function of the embroidery machine head is mostly a single thread take-up function structure, which seriously limits the embroidery efficiency of the embroidery machine. Of course, there are also a few double thread take-up structures, that is, two thread take-up levers that move together. , a structure in which two thread take-up levers move together greatly improves the embroidery efficiency of the embroidery machine, and it cooperates with two embroidery needles to embroider together

The appeal is that the two thread take-up levers move together. The driving method is that a connecting rod connects the two thread take-up levers through the branch at the end to realize the double thread take-up function, but this double thread take-up function is a fixed thread take-up The method is that this connecting rod can only drive two fixed thread take-up levers, and this connection method lacks the adjustment ability for a single thread take-up lever or the adjustment ability is poor and the cooperation with embroidery needles is not good.
