Upper thread clamping mechanism of double-needle embroidery machine

Abstract

The invention relates to the technical field of double-needle embroidery machines, in particular to a double-needle embroidery machine upper thread clamping mechanism which comprises a lower thread passing assembly and an upper thread clamping and loosening assembly. The lower thread passing assembly comprises a pressing strip aluminum seat which is detachably connected with the needle rod frame, and a first mounting hole is formed in the pressing strip aluminum seat; the thread pressing spring seat is detachably connected with the pressing strip aluminum seat, and the thread pressing spring seat is provided with a thread penetrating groove allowing an upper thread to penetrate through from top to bottom; the first elastic ends of the wire pressing springs are connected with the corresponding wire pressing spring seats, and each wire pressing spring seat is connected with at least two wire pressing springs; and the wire pressing sheet is connected with the second elastic end of the wire pressing spring on the corresponding wire pressing spring seat. According to the upper thread clamping mechanism, by arranging the thread loosening connecting rod piece, the two thread loosening push rods can push the corresponding thread passing ejector rods to synchronously move forwards/backwards, and by arranging the at least two thread pressing springs, stable and reliable upper thread clamping force is provided for the thread pressing piece, so that two faces of threads can be stably, reliably and synchronously loosened or clamped.

Description

technical field [0001] The invention relates to the technical field of double-needle embroidery machines, in particular to an upper thread clamping mechanism of a double-needle embroidery machine. Background technique [0002] The upper thread clamping mechanism of the double-needle embroidery machine includes the lower thread passing component and the upper thread clamping and releasing component. The lower thread passing component is mainly used to clamp the two upper threads in the relaxed state at the same time. Release the two upper threads in the clamped state at the same time, and the lower thread passing component and the upper thread clamping and releasing component cooperate with each other so that the two upper threads can pass the thread smoothly. [0003] The patent with the application number CN201921242626.8 discloses a double-needle driven small-head embroidery machine head and embroidery machine, and its upper thread clamping mechanism, such as figure 1 wit...

AI Technical Summary

Problems solved by technology

[0004]The upper thread clamping mechanism in the prior art cannot make the two upper threads perform high-synchronous loosening or clamping operations, and even if the two-sided threads can be clamped with high synchronization However, due to the limitations of its structure itself, the upper thread may not be held stably and reliably. Therefore, the upper thread clamping mechanism of the prior art has the problem that the two upper threads cannot pass the thread efficiently and stably, and the use effect is not ideal. question
