Ultrasonic seamless bonding machine for down jackets

Abstract

The invention relates to a down jacket ultrasonic seamless bonding machine which comprises a base table, an unwinding roller, a winding roller, a stripe pressing plate and an ultrasonic generator, the unwinding roller and the winding roller are located at the end of the base table, the stripe pressing plate and the ultrasonic generator are located above the base table, a plurality of grooves are formed in the upper surface of the base table, L-shaped plates are arranged in the grooves, and two rotating wheels with motors are arranged on the surfaces of the L-shaped plates through U-shaped plates. The U-shaped plate is hinged to the side surface of the L-shaped plate through a hinge shaft, and a plurality of small wheels are arranged on the circumferential surface of the rotating wheel. Through the arrangement of the rotating wheels and the small wheels, fabric / lining is smoothed from the upper end and the lower end in the advancing process, the rotating wheels are driven by the motor to rotate slowly, the fabric / lining is pulled up to the outer side, wrinkling is prevented, the thin blocking piece serves as a support, and the upper rotating wheel and the lower rotating wheel can conduct smoothing treatment on the fabric / lining at the same time; when the fabric / lining moves between the unwinding roller and the winding roller, the small wheels rotate in the moving direction, and the fabric / lining is prevented from generating advancing resistance to cause tensile deformation.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic seamless bonding, in particular to an ultrasonic seamless bonding machine for down jackets. Background technique [0002] Ultrasonic bonding is a fast, clean, and effective assembly process for assembling and processing thermoplastic parts, as well as some composite components. The material to be bonded is placed between the ultrasonic generator and the base, due to the pressure and The vibrations cause mechanical pressure between the material molecules, releasing heat that softens and bonds the material at the joint. [0003] When the down jacket fabric is ultrasonically bonded, it is necessary to unwind the fabric and the lining at the same time, and then ultrasonically bond the fabric and the lining to form a gap between the fabric and the lining, and the fabric and the lining are ultrasonically bonded. When bonding, it needs to be smoothed and aligned. The existing smoothing device can onl...

Problems solved by technology

[0003] When the down jacket fabric is ultrasonically seamlessly bonded, it is necessary to unwind the fabric and the lining at the same time, and then perform ultrasonic bonding on the fabric and the lining to form a gap between the fabric and the lining, and the fabric and the lining are ultrasonically bonded. When gluing, it needs to be smoothed and aligned. The existing smoothing device can only smooth the upper fabric, or smooth the lower lining, and cannot achieve smoothing and alignment at the same time.
