Ultrasonic welding machine

Abstract

The invention relates to the technical field of welding devices, and particularly to an ultrasonic welding machine which comprises a frame body, a welding mechanism and a pressing and holding mechanism which are mounted on the frame body, wherein the welding mechanism comprises an ultrasonic generator mounted on the frame body and welding heads connected with the ultrasonic generator; the pressing and holding mechanism comprises a sliding plate, springs and buffer plates; the sliding plate is connected with the frame body in a sliding manner; the buffer plates are arranged in a manner of being parallel with the sliding plate in a spaced manner; the two ends of each of the springs are connected with the sliding plate and the buffer plates respectively; the buffer plates are positioned between the sliding plate and the welding heads; during practical use of the machine, a document folder to be welded is conveyed to the welding heads, the sliding plate drives the buffer plates to move in the direction close to the welding heads, the buffer plates are utilized to enable the document folder to be butted with the welding heads, and the ultrasonic generator is switched on to perform welding on the document folder; during the welding process, the springs are utilized to perform buffering on the document folder clamped by the welding heads and the buffer plates, and therefore the welding efficiency and quality of the document folder is improved.

Description

technical field [0001] The invention relates to the technical field of welding devices, and in particular discloses an ultrasonic welding machine. Background technique [0002] As one of the commonly used tools for holding paper documents, briefcases are also one of the basic accessories in various office locations. Briefcases are roughly composed of multi-layer plastic films and paper cards installed between the multi-layer plastic films. When actually manufacturing the briefcase, it is necessary to put the paper card between the multi-layer plastic films, and then weld the plastic film and the paper card together; The structural design of the briefcase is unreasonable, so that the welding efficiency and welding quality of the briefcase are extremely low, which cannot meet the needs of modern production. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide an ultrason...
