[0020] The present invention is further described below in conjunction with specific embodiments.

[0021] refer to Figure 1 , 2 3. A detachable needle bar rack comprises an upper portion 1 of the needle bar rack and a lower portion 2 of the needle bar rack. The lower portion 2 of the needle bar rack is detachably connected to the upper portion 1 of the needle bar rack. The lower portion 2 of the needle bar rack is provided with upper and lower rows of needle bar holes 3, and the needle bar holes in the upper and lower rows correspond to each other one by one.

[0022] Furthermore, the needle bar frame is divided into upper and lower parts, which is convenient for disassembly and replacement of the lower part of the needle bar frame. The lower part of the needle bar frame can be replaced to adapt to different machine needles according to actual needs.

[0023] Furthermore, the upper and lower rows of corresponding needle bar holes 3 correspond to the same needle bar, and the upper and lower rows of needle bar holes 3 are very close to each other, which can better ensure concentricity during processing, facilitate the installation and positioning of the needle bar, and also save processing costs, making processing more convenient. The needle bar holes 3 are arranged in parallel for placing multiple needle bars.

[0024] Further, the needle bar frame lower part 2 is installed at the lower end of the needle bar frame upper part 1. The needle bar frame upper part 1 is provided with a groove for accommodating the needle bar frame lower part 2, and the needle bar frame lower part 2 is embedded in the groove and connected with the needle bar frame upper part 1 by bolts.

[0025] Furthermore, a positioning plate 4 and a positioning plate groove 5 are provided between the needle bar frame upper part 1 and the needle bar frame lower part 2 to cooperate in positioning the needle bar frame lower part 2. The positioning plate 4 is arranged in the groove, and the needle bar frame lower part 2 is provided with a positioning plate groove 5 to cooperate with the positioning plate 4. The positioning plate 4 is positioned by cooperating with the positioning plate groove 5, so that the needle bar frame lower part 2 can be quickly and accurately installed on the needle bar frame upper part 1.

[0026] Furthermore, the positioning plate 4 and the positioning plate slot 5 are both provided with screw holes for fixing bolts to pass through. The positioning plate 4 and the positioning plate slot 5 are fixedly connected by fixing bolts, and corresponding screw holes 6 and bolts are also provided between the upper part 1 of the needle bar frame and the lower part 2 of the needle bar frame for installation and connection. The positioning plate 4 and the positioning plate slot 5 can also be provided with positioning holes for installing positioning pins to pass through.

[0027] The lower portion 2 of the needle bar frame is also provided with a presser foot rod groove 8 or a presser foot rod hole corresponding to the needle bar hole 3. In this embodiment, the presser foot rod groove 8 is preferably used to facilitate the installation and positioning of the presser foot rod.

[0028] The lower end of the needle bar frame upper part 1 is provided with an installation opening 7 for accommodating the needle bar frame lower part 2. The installation opening 7 is provided with a matching work reference surface at the corresponding position of the needle bar frame lower part 2; the installation opening 7 is provided with a connection hole matching the needle bar frame lower part 2, and the connection hole can be set on the reference surface for bolt connection. The installation opening can facilitate the overall beauty of the needle bar frame, so as not to affect the use of the existing embroidery machine, and at the same time facilitate the installation of the needle bar frame lower part 2.

[0029] The utility model is provided with an upper part of a needle bar frame and a lower part of a needle bar frame, which are detachably connected to each other, and are convenient for installation and replacement. The lower part of the needle bar frame is provided with upper and lower rows of needle bar holes for placing needle bars, and the upper and lower needle bar holes correspond to each other, and the corresponding needle bar holes are used to place the same needle bar. Since the distance between the upper and lower rows of needle bar holes is very close, it is more convenient to process compared with the prior art and can ensure a higher concentricity between the corresponding holes, while also saving costs. In addition, the lower part of the needle bar frame can be replaced at any time according to the size of the machine needle, so that the size of the machine needle matches the needle bar hole.
