Description

Technical Field

[0001] The utility model belongs to the technical field of moving cloth clamping frames of embroidery machines, in particular to a cloth clamping frame device for embroidery machines with two-way and double-driven motors. Background Art

[0002] The embroidery machine's cloth clamping frame is a crucial control device for positioning the fabric on the embroidery machine. Its control stability and precision significantly impact the quality of the embroidery. Existing drive mechanisms for embroidery machine cloth clamping frames typically operate independently, both horizontally and vertically, from one side. This works well for lightweight, narrow-width, slow-moving, and low-quality applications. However, it becomes unsuitable for applications involving heavy, wide-width, high-speed embroidery machine cloth clamping frames, where quality demands are high. Improving the stability of these devices under these conditions has been a topic of research for those skilled in the art.
