Longitudinal-radial coupled vibration double-roller ultrasonic rolling welding device

Abstract

The invention relates to the technical field of ultrasonic equipment, and aims to provide a longitudinal-radial coupled vibration double-roller ultrasonic rolling welding device. The longitudinal-radial coupled vibration double-roller ultrasonic rolling welding device comprises an ultrasonic vibration part and a fixed clamping part, wherein the ultrasonic vibration part comprises a double-roller seam welding tool head and ultrasonic transducer switches, the double-roller seam welding tool head is arranged coaxial with the ultrasonic transducer switches; the double-roller roll welding tool head is composed of two T-shaped roll welding tool heads which are in butt joint, disc structures at the ends of the two T-shaped roll welding tool heads are connected through bolts to achieve symmetrical arrangement, and the ends of axial amplitude-change poles of the two T-shaped roll welding tool heads are each connected with an ultrasonic transducer; coaxial conductive slip rings are respectively arranged at the end parts of the outer sides of the two ultrasonic transducers; and the fixed clamping part comprises a set of synchronous belt wheels, two sets of fixed shells and two sets of bearings. According to the longitudinal-radial coupled vibration double-roller ultrasonic rolling welding device, it can be ensured that the ultrasonic vibration part achieves the optimal vibration effect at the resonant frequency of the ultrasonic vibration part, and the high-speed rotation function of the ultrasonic vibration part is achieved; and stable feeding is achieved while welding is conducted, the problem of material extrusion in the welding process is solved, and better welding sealing is achieved on different material thicknesses.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic equipment, and in particular relates to a double-roller 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 stitche...

AI Technical Summary

Problems solved by technology

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