Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery, in particular to a sewing head switching mechanism of a quilting machine. Background Art
[0002] A quilting machine is a textile machine specially used for sewing linear patterns on the surface of items such as mattresses, bedspreads, and quilts. It is mainly composed of a fixed frame, a gantry, and a sewing machine head. The gantry is slidably arranged above the fixed frame and is arranged perpendicular to the length direction of the fixed frame. The sewing machine head is slidably arranged on the gantry. The sewing machine head can move along the X-axis and the Y-axis in a plane to achieve the function of sewing linear patterns on the surface of items.
[0003] The sewing machine head is usually integrated with a wire roller. In order to connect the thread end of the wire roller to the needle of the sewing machine head, it usually needs to be wound through several wire management racks. The wire management racks provide support for the wire on the wire roller to prevent the wire from being entangled. Therefore, when the wire wound on the wire roller is used up, the operator usually needs 10-20 minutes to replace the wire roller and correctly pass the wire through the corresponding wire management rack. In addition, because the sewing machine heads of quilting machines on the market cannot be quickly disassembled and assembled from the gantry, the quilting machine must be continuously shut down during the process of replacing the wire roller, which seriously affects the work efficiency of pattern sewing.
