Working Principle and Structure for Vibrating Bowl or Hopper

Here we will explain the vibrating hopper working principle and structure, so you will understand how our hardware packing machine keeps stable performance and high speed.

Bowl hopper is through AC electromagnet of pulsed electro-magnetic-driven flexible structure, form a directional vibration, enabling auto-arrange and direct supply of the workpiece. On the electrical control with TRIAC variable voltage or frequency modulation, step-less speed regulation.

Product Description

The piezoelectric vibration feeder is a kind of vibration feeder in which the driving source is made by the piezoelectric elements whose main components are the piezoelectric ceramic made of titanate and zirconate. It is the use of the piezoelectric element of the applied voltage to produce mechanical deformation of the piezo effect to achieve the vibration and become the landmark feeder of the parts conveyor.

This vibration plate is widely used and can install all kinds of vibration plates by center fixed or fixed around. Because the driving parts do not have the coil and iron core, the electrical and mechanical structure is very simple and has good durability.

Product Feature
1.No need to adjust the spring sheets.
Because through sample controller frequency setting will be able to achieve the desired operational state, so when the machine assembly or the electric frequency 50/60 Hz changes, you don’t need to adjust the resonant spring sheets, and there is no secular variation.
2 No electromagnetic influence on parts
Drive parts do not have any magnetic effect on small parts and magnetic parts, are conductive to the selection of the parts.
3. Most suitable for conveying of small parts
Because it is directly driven by spring sheets, the effective vibration is very big, so that they can achieve the jump-free conveying of the tiny parts.
4. Significant energy saving effect
Because the piezoelectric element of the electric-mechanical energy conversion rate is high, So it can reach more than 70% of the energy-saving effect compared with the past forms.
5. Shared the 100V,200V.
By using a dedicated controller, realized the shared 100V, and 200V.
And can provide stable power by using the「KS-3」sensor.

Main technical parameters
1、 Rated voltage of 220 V or 110 V AC, frequency 50 Hz or 60 Hz, the vibration plate uses half wave excitation or full wave excitation according to the need.
2、 Vibration specification： terminal disk diameter from φ80 to φ1000mm.
3、 Vibration plate is divided clockwise and counterclockwise according to the direction of the material.
Installation, use, and maintenance
1. When opening the package, you need to check whether the whole machine and accessories match.
2. Please check the connections of the host, and make sure that they all fasten stable.
3. When installed that the Damping parts must correspond to the components in the upper and lower holes.
4. After good height and level adjustments, please fasten the vibration plate on the mounting plate.
5. Leave the gaps for the parts connections, so as not to affect the using functions of the vibration.
6. Electrical plugs for the vibration plate are mounted on the electrical control box (Note: electric control box must be oil and waterproof ), connected to 220V or 110V power supply, open the switch, turn the potentiometer slowly, gradually achieve the required feed number. Note: Before connecting power, make sure to adjust the potentiometer to the minimum, so as not to damage the Silicon-controlled rectifier.
※ Electromagnet and armature of clearances and elastic parts are been adjusted before leaving the factory, so you don’t need to adjust it usually.
7. If the vibration plate running for more than two years, chassis parts should be disassembled and cleaned up the dust and dirt on the various parts, and then reinstalled, this is for it to get a good performance.
Common malfunctions and their elimination methods
1. If the power is on but the vibration does not work, please check the electric controller fuse, is it broken? And if it got poor contact between plug and socket in an electrical component, tie them up.
2. Low speed
（1） Check the screw of the base fasten of the vibration plate.
（2） Please check the space between the electromagnet and the gag bit, it is supposed at 0.5-1.2mm, and the core of the electromagnet should be at a parallel level, and their Not parallel degree should not be greater than 0.02 (mm).
（3） check whether the spring was broken or not.
3. The winding of the electromagnet was burned up or maybe the temperature rise too high.
(1)The space between the electromagnet and the gag bit should not be too big because it will be burned, also the speed of the plate should not be more than 200, it will make the coil burn, you can increase or decrease the spring to adjust the vibration.
(2) Suitable for the full wave electromagnet, if used to the half wave power, the temperature will increase.
