Longitudinal-radial coupled vibration integrated ultrasonic roll welding tool head

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...

AI Technical Summary

Problems solved by technology

Due to the difference in line speed between the two, under a certain pressure, it will cause welding quality problems such as wrinkling of multi-layer non-woven products and poor welding sealing.
