Product Description

20kHz 2000W Automatic Frequency Tracking Digital Ultrasonic Welding Generator For Nonwoven

Ultrasonic welding has been widely used in sanitary product production lines, such as diapers and other related products. Many fabrics, films, non-woven fabrics and paper products such as feminine products, medical masks, wipes, vacuum bags, filter cloths, etc. will use ultrasonic welding equipment .
Ultrasonic technology is powerful and has a wide range of applications. It can perform operations such as lamination, embossing, punching, cutting, and splicing. Therefore, ultrasonic welding can not only provide low-cost bonding, but also perform other operations, which improves the utilization of equipment.
The frequency range of ultrasound is 20 kHz to 1 GHz, which is inaudible to the human ear. The frequencies commonly used in ultrasonic welding are 20, 30 and 35 kHz.
How does the ultrasound system produce high frequency vibration
The ultrasonic generator converts the line voltage into a high voltage/high frequency signal and sends it to a converter. In the converter, the piezoelectric crystal is sandwiched between two pieces of titanium metal to vibrate at the frequency of the electrical signal, which generates very fast mechanical vibrations with a frequency of 20,000 Hz per second and an amplitude of 18 μm.


The principle of ultrasonic mask machine welding mainly uses ultrasonic technology to transmit ultrasonic energy to the welding zone through the upper welding piece. Due to the large acoustic resistance at the welding interface, which is the interface between the two weldings, local high temperatures will occur. In addition, due to the poor thermal conductivity of plastics, nylon, chemical fibers, non-woven fabrics, multi-layered fabrics, and gold fabrics, they cannot be distributed in time and gather in the welding zone, causing the two contact surfaces to melt rapidly. After applying a certain pressure, Fusion into one. When the ultrasonic wave stops functioning, the pressure is continued, and the pressure is maintained for a while to solidify and form. This forms a strong molecular chain to achieve the purpose of welding. The welding strength can be close to the strength of the raw material. This is what many manufacturers need to use. NVC ultrasonic welding and welding masks have the advantages of fast, clean, safe, stable performance, high output, etc., and make the wearer's ears comfortable, no pressure, good filtering effect of mask filter cloth layer, and perfectly fit the face of Asians, It is very suitable for the current personal protective masks for epidemic situations, high-pollution red zone protective masks, and can be applied to high-polluting industries such as construction and mining.Standard ultrasonic welding machine Non-woven standard mask machine, 20KHZ1200W-2000W, 15KHZ2600W-4200W ultrasonic welding machine Non-woven welding, plastic welding, welding, PVC leather spot welding, ribbon cutting, heat sealing and other multi-functional welding equipment, outer ear tape The mask machine fuses the elastic bands on both sides of the mask body in an ultrasonic manner to complete the finished earband mask. Only one operator needs to place the mask body on the conveyor belt fixture, and the rest of the subsequent actions until the finished product is completed The machine operates automatically, and the output of this machine is higher than that of ordinary earband machines.
Plane mask machine, automatic mask spot welding machine, ultrasonic mask machine, plane mask spot welder, disposable mask machine, non-woven mask machine, ear band mask machine, N95 mask machine, FFP2 mask machine and other mechanical equipment are required It is equipped with an ultrasonic generator. This supporting equipment is aliased as an electric box and an ultrasonic control box.
The main functions of the ultrasonic generator:
Used for welding and welding of non-woven masks, welding of front-end breathing valve of cup mask, welding of nose bridge line of cup-shaped mask, spot welding of ultrasonic ear band, welding of cup-shaped ear band, plastic shell and plastic parts The generator is versatile.

 

Ultrasonic system for mask machine Ultrasonic vibration system can output ultrasonic vibration energy and can be used in a variety of applications; the system needs to cooperate with actions, pressure and other mechanical units to complete welding tasks; with fixed flanges, simple installation; when the system works, there are external switches The signal triggers the system. The system completes a welding process according to a preset time. The program control circuit is equipped with a delay time, welding time, pressure holding time, and demolding vibration time. The time adjustment accuracy is 0.01s; it can work intermittently. Can also work continuously;
Performance introduction of ultrasonic system for mask machine:
1. Intelligent ultrasonic generator, digital circuit design, automatic frequency scanning without manual adjustment;
2. Frequency, power, current LCD display, ultrasonic amplitude 50%-100% adjustable;
3. Ultrasonic transducers are assembled from Japanese original piezoelectric ceramic chips, with strong and reliable power;
4. The system is equipped with multiple detection protection circuits. When the output cable is open, the transducer and the mold exceed the frequency range, etc., the overload protection circuit automatically cuts off the ultrasonic power supply and buzzes the alarm;
Mask ultrasonic machine special features:
The ultrasonic generator can monitor the working frequency and power of the high-power ultrasonic system.
According to different requirements of users, various parameters can be adjusted in real time: such as power, amplitude, running time, etc.
Frequency fine-tuning: Adjust the frequency so that the ultrasonic transducer always works in a good state, the efficiency is large, and the adjustment range is 2%.
Automatic follow-up: Once the device is initially set up, it can be operated continuously without the need to adjust the generator.
