Car fuel tank welding machine

Servo hot plate welding machine uses the principle of electric heat melting, controls temperature changes, and uses servo drive with perfect mechanical devices to achieve perfect welding, making up for the shortcomings of ultrasonic welding machines for welding large and special plastic workpieces. It is mainly suitable for welding plastic workpieces with large and complex welding of PP, PE and other thermoplastic materials and weld areas.  
Servo hot plate welding machine has the characteristics of simple structure, convenient operation, high production efficiency, etc., after welding can meet the requirements of watertight and airtight, suitable for various shapes, sizes and materials of thermoplastic plastic parts welding, is a wide range of uses, economical and practical, high production efficiency of the welding process. Users can choose a multi-mode welding process according to the process characteristics, production efficiency and degree of automation of various types of plastic parts, and in the process of welding process, several pieces of plastic parts can be welded at the same time, and multi-table hot plate welding machine with a high degree of automation can also be selected for multi-station welding. It is also possible to use a special multi-head hot plate welding machine with multiple welding surfaces to achieve all process requirements for one welding.

Ultrasonic power generators generate signals at a specific frequency (sinusoidal or pulsed) at which the transducer operates.  
 
Ultrasonic equipment typically uses ultrasonic frequencies of 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz, 80KHz, 100KHz or above, which have not yet been widely used.  
 
How to feedback the signal:  
 
The ultrasonic power generator has a feedback link, which mainly provides feedback signals in the following two aspects.  
 
1. Output power  
 
When the input voltage of the ultrasonic generator changes, the output power of the generator also changes. This will make the mechanical vibration of the ultrasonic transducer unstable, resulting in poor working results. Therefore, it is necessary to stabilize the output power and adjust the power amplifier accordingly through the power feedback signal to stabilize the power amplifier.  
 
2. Frequency tracking  
 
The sensor operates at a resonant frequency point, has high efficiency and stable operation.  
 
Due to assembly and aging, the resonant frequency of the sensor changes. If the changed frequency is only drift, the change is not large, the frequency tracking signal can control the signal generator, so that the frequency of the signal generator tracks the resonant frequency point of the transducer within a certain range, so that the generator works in a normal state.
