Thread replacing device and carpet embroidering machine with same

Abstract

The invention provides a thread replacing device and a carpet embroidering machine with the same. The thread replacing device comprises a needle bar rack, a threading frame and a color replacing box, wherein a needle bar is arranged on the needle bar rack; the color replacing box is connected with the threading frame and used for driving the threading frame to transversely move relative to the needle bar. The needle bar rack is of a single needle bar structure; the needle bar rack is fixed to a machine head box, a moving function is cancelled, and thus the possibility that the failure occurs due to movement is lowered; with the single needle bar, a small axis thread is not required to be arranged in the space for storing threads for each needle bar, but a large roll of threads is stored in the space, so that the total quantity of used threads is not changed, but the cost is reduced; with the single needle bar, workers only need to thread the needle bar once, and the needle bar is capable of working all the time and is unlikely to loose threads, so that the work amount of the workers is reduced. With the thread replacing device, the cost of a single product can be effectively reduced, the working efficiency can be improved, and the labor intensity of the workers can be reduced.

Description

technical field [0001] The invention relates to embroidery machine technology, in particular to a carpet embroidery machine thread changing device and a carpet embroidery machine. Background technique [0002] The full name of the embroidery machine is a computerized embroidery machine, which can automatically embroider the designed pattern on the cloth surface. The carpet embroidery machine is based on the embroidery machine, adding various auxiliary devices to realize the function of making carpets. [0003] Such as figure 1 , figure 2 As shown, the needle bar frame 1 is a part on the embroidery machine, which is used to place the frame of the needle bar 10 on the embroidery machine. The needle bar frame 1 can slide on the machine head box 2, and the needle bar frame 1 is connected to the color changer of the embroidery machine. On the box 3, wool yarns 40 of various colors are arranged at intervals on the threading frame 4, and each color of wool 40 corresponds to a ne...

AI Technical Summary

Problems solved by technology

A colorless and transparent silk thread is arranged on each needle bar 10, and woolen yarn 40 of different colors is pressed onto the cloth surface by transparent silk thread during embroidery, when the color of the embroidery pattern on the carpet is richer, the quantity of needed needle bar 10 is also More, because the position space of the needle bar holder 1 for placing the silk thread is limited, only the silk thread of a smaller reel can be placed, the cost of the silk thread of this small reel is higher than that of a large reel, and the cost is high during mass production; each needle bar All the needle points on the needle rod frame must pass through a silk thread, and the workload of the worker is large; in addition, there are many needle rods 10, and there is only one needle rod 10 in the working state all the time, while the rest of the needle rods on the needle rod frame 1 do not move. At this time, due to the friction and scratching effect of the woolen yarn and the thread ends on the finished surface, the silk thread is very easy to break and come out from the needle point, and the worker needs to thread the thread again, and the workload is heavy; Parts are prone to failure during movement, reducing work efficiency
