Principle and structure characteristics of ultrasonic crosscutting machine

With the development of the domestic economy and the overall environment changes, the production of many industrial products on the machine is more and more high requirements, not only need to achieve fast and safe production, but also to achieve a high degree of mechanical automation, while saving production costs; This is a high requirement for the machine, the demand to reach a certain level of planning, and performance in this above, is the company's technical development strength. As the most dust-free cloth used in asepsis room may wipe cloth, because it is a disposable product, the demand is huge, the traditional production of dust-free cloth machine has been unable to meet the needs of the market now, in this premise, as the "hero" of today's introduction - ultrasonic crosscutting machine came out.

The principle of ultrasonic crosscutting machine is completely different from that of traditional cutting. It uses the energy of ultrasonic wave to heat and melt the part of the material to be cut, and then reach the intention of cutting the material. Therefore, ultrasonic cutting does not need a sharp edge, only need to add a little pressure when cutting, you can achieve perfect cutting. And because ultrasonic crosscutting machine is the use of ultrasonic cutting, it is cutting at the same time, in the cutting part of the fusion effect. Cutting parts can be done to be perfect edge sealing, can prevent the loose cutting data organization (such as textile data flying edge) or the phenomenon of yellow and coke cutting, can greatly save the waste of data.

The structure features of ultrasonic crosscutting machine: ultrasonic crosscutting machine is mainly composed of ultrasonic electric box, ultrasonic transducer, horn, cutting knife (thing head) and so on. First of all, the ultrasonic electric box converts the mains electricity into high frequency and high voltage alternating current, which is output to the ultrasonic transducer. After the piezoelectric effect inside the ultrasonic transducer, the input electrical energy is converted into mechanical energy, that is, the ultrasonic wave, which is manifested in the form of the transducer in the longitudinal high frequency telescopic movement. The frequency of the telescopic motion is equal to the high frequency ac frequency supplied by the driving power supply. The main effect of the horn is to enlarge the output amplitude of the transducer to reach the demand of industrial production, and adjust the amplitude of different sizes, which can be achieved by replacing the amplitude rod. The cutting knife (east-west head) on the one hand further amplifies the amplitude and gathers the ultrasonic wave; on the other hand, it outputs the ultrasonic wave. The similar cutting edge of the cutting knife is used to concentrate the input of ultrasonic energy to the cutting part of the data to be cut. The part under the effect of ultrasonic energy, instant softening, melting, strength greatly reduced, and then apply a small cutting pressure, to reach the intention of cutting data. When cutting the data, the data is mainly softened and melted by ultrasonic energy, the cutting edge of the cutter only plays the effect of slit positioning, ultrasonic energy output, separation of data.

Ultrasonic cross-cutting machine is mainly suitable for: such as asepsis room clean cloth cutting, optical lenses and glasses wiping cloth, large cloth cutting piece curtain cloth, plastic products processing, non-woven bag production, thin artificial resin paint (suitable for large area) all types of paper, large production clothing factory cutting and so on.
