Embodiment Construction

[0028] The technical solution of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0029] refer to figure 2 , the one-piece ultrasonic roll welding tool head with longitudinal-diameter coupling vibration provided by the present invention includes an integrally processed end disc structure 11 and an axial horn structure 12, and the overall axial section is T-shaped; The end of the horn structure 12 is provided with a counterbore 21 with an internal thread or a stud with an external thread for connection and installation with an external ultrasonic structure. On the outside of the end (counterbore 21) of the axial horn structure 12, a wrench hole 22 is provided for installation and use when connecting with an external ultrasonic structure. In the middle of the axial horn structure 12, flanges 23 are provided on the radial surface at the joints for fixed connection with the external ul...

Abstract

The invention relates to an ultrasonic welding technology, and aims at providing a longitudinal-radial coupled vibration integrated ultrasonic roll welding tool head. The tool head comprises an end part circular plate structure and an axial amplitude-change pole structure which are integrally machined, the overall axial section of the tool head is in a T shape, and the tail end of the axial amplitude-change pole structure is provided with a counter bore with an internal thread or a stud with an external thread. According to the longitudinal-radial coupled vibration integrated ultrasonic roll welding tool head, rolling contact of the integrated ultrasonic roll welding tool head and an auxiliary roller is realized, so that linear speed synchronization between the integrated ultrasonic roll welding tool head and the auxiliary roller is realized, and therefore, the problem of material extrusion in the welding process is avoided, better welding sealing can be achieved on different material thicknesses, the problem of material extrusion is synchronously solved, larger welding pressure can be allowed between the the integrated ultrasonic roll welding tool head and the auxiliary roller, the welding speed can be remarkably increased under the condition of the same amplitude, the impact force borne by the radial surface of the end part circular plate structure cannot directly act on a transducer of an external ultrasonic structure, the risk of transducer damage is greatly reduced, installation is convenient, and use requirements of most welding scenes can be met.

Description

technical field [0001] The invention belongs to the ultrasonic welding technology, and in particular relates to an integrated ultrasonic rolling welding tool head for longitudinal-diameter coupling vibration of an ultrasonic rolling welding device. 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 fo...
