Folding control system
The control system consists of a time timer or an integrated circuit timer.
1. Control ultrasonic generator working time, this system makes the whole welding process automation, operation only start button to create a trigger pulse, can finish automatically during the welding process.
2. The control of pneumatic transmission system work, make its welding under the timing control open pneumatic valves, cylinder pressure make the welding head drop, at a certain pressure by welding objects, when after the welding pressure maintaining a period of time, then will pneumatic reversing valve control system, to reset the welding head picks up.
3. The order of the whole control system is: the power to start a trigger control signal pressure transmission system, cylinder pressure welding head down and work pressure welding trigger ultrasonic generator, ultrasonic launch and maintain a certain welding time remove the ultrasonic emission to keep certain pressure back pressure, welding head picks up end of welding.
Folding pneumatic drive system.
Include: niigata, pressure reducing valve, oil mist, commutator, throttle valve, cylinder and so on.
At work, the pneumatic cylinder is driven by the air compressor to drive up and down the vibration system of the ultrasonic transducer, and the pressure in the ultrasonic welding of medium and small power is adjusted according to the welding needs.
Folding ultrasonic tool head.
Tool head, with amplitude amplification and two without amplitude amplification, plastic welding machine with acoustic system tools, materials for aluminum alloy, usually the end face hard alloy plating, power is larger also useful titanium alloy materials, the material fatigue strength is twice as tall as aluminum alloy.
Different welding objects need to have different tool heads, whether in the near field welding or transmission welding, only half wavelength of the tool head can achieve the maximum amplitude of the welding end face.
Fold the ultrasonic generator.
1. The generator of ultrasonic welding machine with power above 500W adopts self-excited power oscillator, which has certain frequency tracking ability.
2. High power ultrasonic welding machine, the generator signal adopts the lock phase frequency automatic tracking circuit, so that the output frequency of the generator is basically consistent with the resonant frequency of the transducer.
Folding ultrasonic transducer.
The acoustic system for ultrasonic plastic welders consists of three parts: the driving part, the fixed part and the working part. In the above three parts, the driver is the core, generally adopts bolt clamping longitudinal vibration transducer, the half wave vertical oscillator with a quarter of the wavelength of longitudinal vibrator, half the wavelength of longitudinal vibration and the half wave shaped device connected to form a full wavelength plastic welding transducer, and the quarter wave vertical oscillator with quarter wave shaped device connected to one and a half wavelength transducer.
