Over-three-thread embroidery machine nose with head-spacing function

Abstract

The invention discloses an over-three-thread embroidery machine nose with a head-spacing function. The over-three-thread embroidery machine nose comprises an embroidery machine nose body and a needle bar shelf, two or more needle bars and thread-picking bars are installed on the needle bar shelf, the needle bars are driven by a needle bar driver, thread-picking bars are driven by a thread picking shaft, the needle bar driver comprises a first needle bar driver body and a second needle bar driver body, the first needle bar driver body is inserted into the first needle bar to drive the first needle bar, and the second needle bar driver body is inserted into the second needle bar to drive the second needle bar at the same time. After the needle bar shelf is moved, the first needle bar driver body or the second needle bar driver body is inserted into the fifth needle bar to drive the fifth needle bar. Through the dual-needle embroidery function, the first kind of embroidery head distance is generated, after the needle bar shelf is moved, the first needle bar driver body or the second needle bar driver body is inserted into the fifth needle bar to drive the fifth needle bar, and the single fifth needle bar is combined with a fifth needle bar on an adjacent embroidery machine nose to generate the second kind of embroidery head distance, that is, the head-spacing function is enabled.

Description

technical field [0001] The invention relates to an embroidery machine head, in particular to an embroidery machine head with more than three needles and the function of separating heads. Background technique [0002] At present, for the embroidery machine heads, the pattern spacing or the head distance during the embroidery process is fixed. The general method to change the head distance is to shut down the heads on the embroidery machine. For example, shut down No. 1, No. 3 and No. , Between No. 4 and No. 6 heads, there is a second head distance, that is, the pattern distance. This method of changing the head distance is also called the head separation function. The current head separation function needs to shut down part of the heads. Obviously, it is not suitable for embroidery. The performance and efficiency of machine embroidery are greatly affected, especially for high-efficiency double-needle machines, that is, the heads of double-needle embroidery cannot realize the ...

[0002] At present, for the embroidery machine heads, the pattern spacing or the head distance during the embroidery process is fixed. The general method to change the head distance is to shut down the heads on the embroidery machine. For example, shut down No. 1, No. 3 and No. , Between No. 4 and No. 6 heads, there is a second head distance, that is, the pattern distance. This method of changing the head distance is also called the head separation function. The current head separation function needs to shut down part of the heads. Obviously, it is not suitable for embroidery. The performance and efficiency of machine embroidery are greatly affected, especially for high-efficiency double-needle machines, that is, the heads of double-needle embroidery cannot realize the ability to separate heads. How to realize the ability to separate heads without shutting down the machine has always been a technology in the field. object of research

[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.
