Description

Ultrasonic three-side cutting sealing device

Technical Field

The invention relates to the technical field of edge cutters, in particular to an ultrasonic three-side cutting and sealing device.

Background

Carry out trilateral of cloth and purchase when sealing at present, often can only seal and accomplish one side after the manual work from newly placing the cloth and carry out the second time and seal, and the third still needs the manual work to place once when sealing, work efficiency is low, and fixes a position inaccurately, and the product percent of pass of producing is not high, and current cloth cutting seals in addition and often needs two kinds of devices to go on, has further reduced work efficiency.

Ultrasonic waves are a form of wave motion that can be used as a carrier or medium for detecting and carrying information (e.g., B-ultrasound, etc. for diagnostics); powerful ultrasound is also a form of energy which, when its intensity exceeds a certain value, can be affected by interaction with the medium through which the ultrasound propagates, changing so as to destroy the state, nature and structure of the latter. The ultrasonic edge cutter utilizes high-frequency oscillation to transmit sound waves to a welding surface of a workpiece through a welding head, so that the molecules of the workpiece generate friction instantly to reach the melting point of a product, thereby completing the rapid dissolution of a solid material and completing the edge cutting.

Compared with a cold trimming process, ultrasonic trimming and welding of the thermoplastic material can be carried out simultaneously, and compared with a hot trimming process, the cloth edge processed by ultrasonic trimming is soft, uniform in trimming, free of thickness change and ultra-thick phenomenon and free of welding beads; because the material is heated from inside to outside, the temperature is not high, the color of the cut edge is not yellow, the processing process is harmless to the environment, in addition, the processing process does not produce smoke and odor, and the danger of burning and scorching is eliminated.

The existing ultrasonic edge trimmer needs to manually press the fabric during working, the fabric to be processed can be controlled to ensure that the fabric cannot deviate, the position of the fabric cannot be automatically adjusted, the fabric needs to be manually changed for processing, and the working efficiency is low.
