principle:
Piezoelectric vibration plate is a new type of vibration feeding device, is the use of piezoelectric ceramics as a driving source, with many traditional vibration feeding device does not have the characteristics. Vibration plate and silo, linear feeder, electronic control device is configured for automatic feeding system, widely used in batteries, electronic connectors and other electronic components, hardware, medical supplies equipment, food, packaging and other industries.
Piezoelectric vibration plate is the main principle of the use of piezoelectric film counter-piezoelectric effect of vibration, as the drive source to drive the material tank to achieve the delivery of materials.
main feature:
First, the application of piezoelectric film as the driving source, no motor, electromagnetic exciter and other drive devices, and no shaft, rod, belt and other mechanical transmission components, simple structure, easy processing;
Second, change the drive signal amplitude, pulse width and frequency of any one, can adjust the transport rate, control parameters, controllability is good;
Third, in the low frequency segment or ultrasonic work, the noise is small;
Four, in the resonance or no resonance state of work, so less energy consumption;
Five, do not produce interference with the electromagnetic field, nor the impact of electromagnetic interference signals;
Six, no rotation inertia, almost no acceleration and deceleration process, start, stop quickly, fast response performance;
Seven, simple structure, installation and maintenance more convenient.
the difference:
1, electromagnetic vibration plate is an electromagnetic vibrator (electromagnetic suction and armor general term) for power, the electrical energy into mechanical vibration energy, hopper below a pulsed electromagnet, can make the bucket vertical vibration, due to multiple groups (3 groups and above) of the spring, so that the hopper around the vertical axis to do torsional pendulum vibration. The parts of the hopper, due to this vibration, rise along the spiral track until they are sent to the discharge port.
2, Piezoelectric vibration plate is the use of piezoelectric ceramics as a driving source of the new vibration feeding device, which uses the piezoelectric film of the reverse piezoelectric effect of vibration, as the drive source drive trough to achieve the transport of materials. It has many traditional vibration feeding device does not have the characteristics:
(1) simple structure, installation and maintenance more convenient;
(2) the use of piezoelectric film as a driving source, no motor, electromagnetic exciter and other drive devices, and no shaft, rod, belt and other mechanical transmission components, simple structure, easy processing;
(4) no change in the inertia, almost no acceleration and deceleration process, start , Stop quickly, fast response performance;
(5) does not produce interference electromagnetic field, nor is it affected by electromagnetic interference signal;
(6) work in low frequency or ultrasonic section, the noise is small;
(7) in the resonant or non-resonant state of work, so less energy consumption;
(8) the driving force is slightly insufficient, can not send too heavy material parts, so most of these devices used in the material trace or precision transport.
Disadvantages:
The driving force is slightly insufficient, can not send too heavy material parts, so most of these devices used in the material trace or precision transport. Straight feeder because only before and after the two sets of spring in the same horizontal tilt, the material in the feeder track only horizontal movement.
