Ultrasonic Cup Mask Welding Machine

The principle of Ultrasonic Cup Mask Welding Machine is that the 15-40khz high-frequency signal generated by the generator is converted into high-frequency mechanical vibration through the energy conversion system. At the same time, the welding tool head exerts high pressure on the plastic workpiece, so that the transmission part passing through the workpiece surface and the inherent molecules rub against each other, thereby raising the temperature. When the workpiece itself reaches the melting point, the joint of the workpiece will melt rapidly. When the vibration stops, the workpiece is cooled under a certain pressure, and then perfect welding is achieved. Ultrasonic welding is a high-tech for welding thermoplastic and plastic products. All kinds of thermoplastic rubber can be processed by ultrasonic welding without adding solvents, adhesives or other additives. This improves productivity and product quality, while reducing costs.

Product feature and application

1. The automatic frequency modulation function enables the Ultrasonic Cup Mask Welding Machine to automatically track and compensate the frequency change of the welding head. When the temperature is too high, the frequency of the machine will change.

2. Built in automatic constant amplitude system can automatically compensate for different pressure changes and voltage fluctuations. The ultrasonic amplitude is stepless adjusted from 50% to 100% to meet the requirements of different welding workpieces.

3. Using IGBT for power amplification, the reaction speed is fast, more than 100 times faster than the traditional silicon power tube, with better protection function.

4. Fast welding speed, high welding strength, good sealing.

5. Replace the traditional welding / bonding process, low cost, clean and pollution-free, and do not damage the workpiece.

6. Stable welding process, convenient operation and maintenance.

7. Light weight, all have resonance when no-load, and there is no need to adjust the frequency of the welding head.

8. Aluminum / titanium radial rod, strong stability.

9. The Ultrasonic Cup Mask Welding Machine is equipped with air cylinder and solenoid valve, which has stable performance.

There are currently three common types of ultrasonic plastic welding machines in the market:

1. Screw type ultrasonic plastic welding machine:

The main feature of the screw type ultrasonic plastic welding machine is to use a screw transmission mechanism to drive the pressure device to generate pressure and drive the transducer to generate high-frequency vibration waves, which are transmitted to the welded material to complete the welding process; It has a simple and compact structure, convenient and flexible operation, and high production efficiency.

2. Both drum and rotary ultrasonic plastic welding machines use gear transmission to drive the material pressing device to generate pressure and drive the transducer to generate high-frequency vibration waves, which are transmitted to the welded material to complete the sewing process.

3. Compared with drum type, rotary type has a wider range of applicability (suitable for materials of different thicknesses and shapes) and better efficiency (saving more than 30% compared to the former under the same power).

With the development of industry and the increasing demand for product performance, as well as the increasing emphasis on environmental protection, more and more industries are using ultrasound to control and manage the appearance quality of products.

For example, the door sealing strip in the automotive industry can achieve good sealing effect through ultrasonic treatment, thereby improving the quality of air inside the car; For example, component packaging in the electronics industry also achieves good edge effects through ultrasonic processing, and so on.

It can be seen that the application of ultrasound has been very extensive.
