The invention discloses a high-speed single needle bar drive head which comprises a housing and a head assembly in the housing. The head assembly is mounted on a main beam of a quilting embroidery machine, a transmission main shaft is arranged on the quilting embroidery machine, and a plurality of driving gears are mounted on the transmission main shaft. The head assembly comprises a driven gear, a driving crank, a needle bar crank, a jumper bar, a needle bar connecting rod, a sliding block frame, a connection shaft, a guide rod, a sliding block (A), a sliding block (B), an electromagnet frame (A) and an electromagnet frame (B), and two electromagnets are correspondingly arranged beside the sliding block (A) and the sliding block (B) and are respectively mounted on the electromagnet frame (A) and the electromagnet frame (B). The high-speed single needle bar drive head has the advantages that when the electromagnets work, the ends of the sliding blocks are blocked by electromagnet blocking members and then the sliding blocks rotate around sliding block pins, so that U-shaped grooves on the opening portions of the sliding blocks can be separated from a connecting shaft on the needle bar to enable the needle bar to stop working; and when the electromagnets does not work, the sliding blocks move to the original positions under the action of torsion springs.
Description
technical field [0001] The invention relates to a quilting and embroidery machine head, in particular to a high-speed single-needle-bar-driven machine head of an all-in-one quilting and embroidery machine mainly used for fabric pattern processing in industries such as home textiles, clothing, home decoration, and car decoration. The utility model belongs to the technical field of sewing machinery in special equipment for light industry. Background technique [0002] With the renewal of people's consumption concepts and the improvement of aesthetic views, in recent years, the home textile, clothing and other industries have higher and higher requirements for quilting and embroidery of fabric fabric patterns, including operational performance, scope of application, production capacity, etc., which need to be continuously introduced. Quilting and embroidery processing equipment that meets the needs of market development. Therefore, it is more challenging for the technical leve...
