Abstract

The invention relates to an ultrasonic equipment technology, and aims to provide a longitudinal-radial coupled vibration ultrasonic rolling welding device. The device comprises an ultrasonic vibration part and a fixed clamping part, a cylindrical fixed shell is coaxially arranged outside an amplitude-change pole in a sleeving mode, and one end of the cylindrical fixed shell is fixedly connected with a flange, protruding in the radial direction, on a roll welding tool head; a synchronous pulley and two bearings are coaxially arranged outside the fixed shell in a sleeving mode, a bearing positioning sleeve is arranged between the two bearings to keep a distance, and outer rings of the bearings are fastened and mounted in a supporting plate; and a conductive slip ring is coaxially and fixedly connected to the end part of a transducer shell. According to the device, the conflict coordination problem existing in the ultrasonic isolation, fixing and rotating modes of a longitudinal-radial coupling vibration system in the prior art is solved, the optimal vibration effect of the ultrasonic vibration part can be ensured, ultrasonic waves are effectively isolated at the vibration frequency, and meanwhile, the high-speed rotating function of the ultrasonic vibration part is realized.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic equipment, and in particular relates to an ultrasonic rolling welding device with longitudinal-diameter coupling vibration. Background technique [0002] The principle of ultrasonic non-woven fabric welding is similar to that of ultrasonic plastic welding. It is to sew (weld) some chemical fiber fabrics with thermoplastic material properties or blended fabrics containing chemical fiber raw materials, which can be classified as a type of ultrasonic plastic welding. Compared with the traditional sewing machine assembly needle, thread and bobbin sewing technology, it can improve production efficiency, and the appearance and quality of sewing lace are improved. It can be applied to garment lace, bed cover, pillow cover, TV cover, car cover, sofa cover, windbreaker, raincoat, footwear, hat, travel bag, tent, packaging bag, PVC handbag, film for packaging food, Napkins, etc. are stitched. It has br...
