[0002] Referring to Chinese patent application CN114232235A, the disc tape embroidery machine on the market, the structure of multi-color disc tape embroidery mainly comprises a plurality of disc tape discs arranged on the circumference of an M-axis assembly, and the plurality of disc tape discs rotate around the circumference of the M-axis to send the required disc tape disc to the needle to complete color changing. However, due to the limited circumferential space of the M-axis assembly, the disc tape discs arranged are generally two, and it is difficult to arrange more disc tape discs, so that the number of color changing of the multi-color disc tape embroidery is limited.

[0003] Referring to Chinese patent application CN116288975A, when the color changing head needs to be taken off from the sewing station, a loading mechanism moves into the sewing station to cooperate with the clamp of the color changing head to open the clamp, and the loading mechanism unloads the color changing head in the sewing station and carries it back to the left and right moving mechanism to load it; when the color changing head needs to be loaded into the sewing station, the loading mechanism cooperates with the clamp of the color changing head in the left and right moving mechanism to open the clamp, and the loading mechanism moves the color changing head corresponding to the color tape in the left and right moving mechanism to the sewing station, so that the color changing head is connected to the needle bar mechanism through the clamp, thereby completing the automatic loading work of the color changing head. However, the above structure needs to unload the color changing head on the original station and load it into the left and right moving mechanism, and then control the left and right moving mechanism to load the new color changing head into the sewing station. The two processes of unloading and loading need to be performed in sequence and cannot be performed synchronously, which leads to a long time for the loading work, and the embroidery work also stops accordingly during the loading process. Therefore, the long loading time causes the embroidery efficiency to be reduced, and the loading mechanism needs to be further optimized and improved. SUMMARY
