20Khz 2000w Ultrasonic Welding System For Mask Earloop Welding

20Khz 2000w Ultrasonic welding system for mask earloop welding

Parameter

Description

The ultrasonic mask welding machine uses high-frequency vibration waves to be transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects are rubbed against each other to form a fusion between the molecular layers.

Some indentations can be seen everywhere on the mask, such as the edges, ear straps, and exhalation valve are all ultrasonically welded. As shown in the figure above, in the production process of masks, we can intuitively understand the welding of all-plastic nose bridge, welding after hemming, breathing valve welding, multi-layer seam welding, and ear band welding. These are actually all made by ultrasonic welding process. Completed.

When the ultrasonic wave acts on the thermoplastic plastic contact surface, it will generate tens of thousands of high-frequency vibrations per second. This kind of high-frequency vibration with a certain amplitude will transmit the ultrasonic energy to the welding area through the upper weldment. Because the welding area is two The acoustic resistance at the welding interface is large, so local high temperature will be generated. In addition, due to the poor thermal conductivity of the plastic, it cannot be distributed in time for a while, and it gathers in the welding area, causing the contact surface of the two plastics to melt rapidly, and after a certain pressure is applied, they are fused into one.

Composition of ultrasonic mask welding machine

The ultrasonic generator converts the power current of 110VAC or 220VAC into high-frequency and high-voltage electrical signals.RPS-SONIC ultrasonic generator has the following advantages:

Lock the main resonance: All ultrasound systems have a main resonance (ideal working resonance), in addition, there will be a second (false) resonance. When the power is turned on, the RPS-SONIC ultrasonic generator will lock the primary resonance and ignore the secondary resonance.

Tracking the main resonance: During the ultrasound operation, the frequency of the main resonance may shift. As the temperature of the battery stack increases, the frequency may decrease (due to internal loss or heat transferred by the load), and the ultrasonic generator can automatically track the frequency shift and continue to work stably.

Automatically adjust the amplitude: RPS-SONIC ultrasonic generator can achieve the best control by controlling the output amplitude. The thickness of the welding material can be adjusted to ensure that the same welding can weld ordinary medical masks and KN95 professional masks.

The ultrasonic transducer uses the high-frequency electrical signal from the ultrasonic generator and converts it into linear mechanical motion. This conversion is performed by using piezoelectric ceramic disks, which expand when a voltage is applied. The transducer used for ultrasonic rubber cutting is specially designed, and air can be introduced and discharged in it for cooling.

Mask machine customization

At the same time, we can also customize various ultrasonic transducers according to customer needs to meet the needs of production. For more information on the customization of ultrasonic transducers, please see.

Hangzhou Jiazhen Ultrasonic Technology focuses on the development, design, and customized services of power ultrasonic transducers and related materials. The company has experienced ultrasonic transducer design engineers and many years of experience in new product development and design, and has passed the depth of research institutions The cooperation has formed a systematic and standardized technical system to ensure the quality of ultrasonic transducers/ultrasound probes in development, testing, performance calibration and stability.

R-Responsibility P-Products S-Service

sale the right products instead of the expensive one

Rps-sonic, consisted with a couple of young people who love ultrasonic very much.The founding members of RPS-SONIC have an average degree of Bachelor's degree or above. They have been in the ultrasonic industry for more than 5 years and have rich experience in ultrasound. The company's business philosophy is: Do not blindly promote any product, find the right product for the customer. So before each order, we will confirm all the details, including application details, equipment conditions, equipment specific information.

And we have the Professional import and export company， HangZhou LanBen Trade Co., Ltd, can export to any country wordwide.

Before year 2012, we only sale second branson / dukane / rinco / herrman/telsonic welding equipment , during these twenty year develop, we find, more and more people have problem with the core part of ultrasonic welding equipment -generator and transducer, so we decided to start our business of transducer and generator of our own transducer and generator. Many of the end user meet the transducer problem, they don’t know why transducer broken, and changing the expensive transducer one by one. Actually, one branson /dukane /rinco transducer can use 10~30 year, even the cheapest transducer can use about 5 years. So there must some reasons if your transducer broken in one year. That’s why we want build Rps-sonic, we need to help more end user to know more about transducer , to use ultrasonic equipment better, to save cost when meet problem.

The same to generator, Unreasonable operation may shorter the use-life of ultrasonic generator. So we have to make technical inquiry before operate ultrasonic welding machine. The key point of ultrasonic machine is resonance, only keep every part in resonance can make the system in best work environment.

Till now , we still have a lot of Branson /dukane/ rinco/ herrman telsonic welding machine, so that we can confirm every transducer/generator we made can matching to the original machine.

Of course we can make the transducer/generator replace for Branson /dukane/ rinco/ herrman telsonic welding machine, we can also make transducer/generator for any application of your ultrasonic equipment. We supply OEM service for oversea customers, we already have OEM customer in USA and German.

If you have any problem in ultrasonic area, welcome contact Rps-sonic.
