Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, specifically an ultrasonic welding machine. Background Technology

[0002] Ultrasonic welding machines transmit ultrasonic waves through a welding head to plastic parts, causing intense friction between the two plastic surfaces. The frictional heat melts the surfaces, resulting in a bond. This technology offers advantages such as high speed and strong welds. More importantly, it automates the production and processing of plastic products. Ultrasonic plastic welding machines can perform operations such as plastic welding, embedding, forming, riveting, spot welding, cutting, and sewing. By simply modifying the welding head, a single machine can perform multiple applications.

[0003] An existing ultrasonic welding machine, with application number 202120289569.X, includes a base, on which the welding machine body is movably mounted. A hinge is fixedly installed on one side of the inspection door surface. This ultrasonic welding machine can quickly fix the lower mold and speed up disassembly and installation during maintenance. However, it cannot provide external isolation protection for the welding station, and the welding joint is easily touched during operation, thus affecting the safety of the welding operation.
