Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a color changing device suitable for the head of a computer embroidery machine. Background Art

[0002] Computerized embroidery machines are high-tech automated embroidery equipment that use a computer control system to convert patterns into instructions and control the coordinated operation of components such as the machine head and embroidery frame. The machine head has an embroidery needle and a color-changing device, while the embroidery frame fixes the embroidery material and moves. It has the characteristics of high efficiency, high precision and versatility, and plays an important role in the modern embroidery industry.

[0003] The color-changing mechanism is crucial within a computerized embroidery machine, enabling rapid switching between different thread colors to meet diverse embroidery needs. When the screw-driven color-changing mechanism operates, the computer control system issues a color-change command, which drives the motor to rotate the screw. The threads on the screw interact with the color-changing component, pushing it axially. This movement propels the embroidery needle to the corresponding thread color, achieving precise color changes.

[0004] The surface of the existing color-changing device does not have a cleaning function. If dust remains on the surface of the screw, the dust will interfere with its normal operation when the screw rotates to drive the color-changing part to move, resulting in an error in the moving distance. This will make it impossible for embroidery threads of different colors to stay accurately at the preset embroidery position, resulting in the embroidery product not meeting the requirements.
