Description

Technical Field

[0001] This utility model belongs to the field of embroidery machine technology, and specifically refers to a color-changing structure for embroidery machines. Background Technology

[0002] Currently, the color-changing frame of common embroidery machines on the market consists of a base plate, a left side plate, and a right side plate. The left and right side plates are fixed to the base plate with bolts. Installing the motor and color-changing cam on the color-changing frame is quite cumbersome. For example, first, the left side plate is fixed to the base plate with bolts, and the color-changing cam is set on the left side plate through the camshaft and flange periphery. Then, the right side plate is fixed to the base plate with bolts. Next, the motor shaft is aligned and inserted into the connecting hole of the camshaft. Finally, the motor is fixed to the right side plate with bolts. The overall connection is quite complicated. Furthermore, the color-changing frame is composed of a base plate, a left side plate, and a right side plate. Over time, gaps will develop, making the color-changing frame unstable and affecting the color-changing effect later. Utility Model Content
