How to find vibration frequency for vibrating feeder

Vibrating feeders are indispensable equipment in modern automatic production lines. They are especially important in industries such as electronics, mechanics and food. This equipment helps automate the feeding process, ensuring that parts are delivered to the right place, in the right direction and at the right time.

One of the important factors that determines the performance of a vibrating feeder is the vibration frequency. So how do you know the current vibration frequency of the machine? How to determine the appropriate vibration frequency for each type of material and production requirements? What factors affect the selection of vibration frequency?

This article, SWOER will guide you through finding the right vibration frequency for your vibrating feeder. This will help you operate your equipment efficiently and achieve optimal productivity.

What is the vibration frequency?

Vibration frequency is measured in Hertz (Hz), which represents the number of times the feeding bowl vibrates in one second. In other words, it indicates how fast or slow the feeding bowl vibrates.

Vibration frequency directly affects the movement speed of the material in the feeding bowl.

• Low frequency: Slow moving materials. Suitable for heavy, fragile parts that need to be moved gently to avoid damage. Applications that require slow feed speeds.
• High frequency: Fast moving material. Suitable for small, light parts. Applications requiring high feed rates.

How to find the current vibration frequency of a vibrating feeder

Determining the current vibration frequency of a vibrating feeder is the first step in optimizing the performance of the equipment. There are two main ways to do this:

Using measuring devices

• Tachometer: This device measures the rotation speed of the vibrating motor and calculates the vibration frequency. You just need to contact the measuring head with the motor's rotating shaft, then read the rpm value on the screen and calculate the vibration frequency.
• Vibration meter: This device directly measures the vibration of the feed bowl, helping to determine the vibration frequency. Attach the probe to the feed bowl and read the vibration frequency value on the screen.
• Stroboscope: This device emits a flashing light with an adjustable frequency. When the flashing frequency matches the vibration frequency of the charging bowl, the charging bowl will appear to be stationary. To use, shine the light on the charging bowl, adjust the flashing frequency until the charging bowl appears to be stationary, and then read the frequency value on the light.

See specifications

• Check the document: See the specifications of the vibrating feeder in the user manual, catalogue or on the manufacturer's website. Information about the vibration frequency is usually clearly stated in the documentation.
• Contact the manufacturer: If you cannot find information about the vibration frequency in the documentation, you can contact the manufacturer directly for support.

Determine the appropriate vibration frequency for the vibrating feeder

Determining the optimum vibration frequency for a vibrating feeder is a prerequisite for ensuring efficient feeding. The appropriate vibration frequency improves productivity and product quality. It helps the material move steadily and continuously without being thrown out or jammed in the feeding bowl.

Factors affecting the selection of vibration frequency

Material properties

• Size: Small materials often require higher vibration frequencies to move quickly. Large materials may need lower vibration frequencies to avoid being thrown out.
• Shape: Complex shapes may require careful adjustment of vibration frequency and amplitude to ensure precise movement and orientation.
• Weight: Heavy materials require lower vibration frequencies to avoid damaging the feed bowl or causing excessive vibration.
• Friction: High friction materials require higher vibration frequencies to overcome the friction and move easily.
• Adhesion: Highly adhesive materials require higher vibration frequencies to avoid sticking to the feed bowl.

Feed bowl shape and size

• Diameter: Larger diameter feed bowls typically require lower vibration frequencies.
• Slope: The slope of the spiral affects the speed at which the material moves, which in turn also affects the vibration frequency.
• Height: Taller feed bowls may require higher vibration frequencies to move material to the top.

Feeding requirements

• Speed: High feed rate requirements require higher vibration frequencies.
• Accuracy: If high accuracy in positioning and feeding is required, the vibration frequency should be carefully adjusted.
• Productivity: High productivity requirements often require higher vibration frequencies to ensure feed rates.

Test method to determine suitable vibration frequency

1. Start with low frequency: Start the vibrating feeder at low frequency.
2. Increasing frequency: Gradually increase the vibration frequency and observe the flow of material in the feed bowl.
3. Observe and adjust: If the material moves too slowly, increase the vibration frequency. If the material moves too fast or is thrown out, reduce the vibration frequency. If the material is jammed, adjust the vibration frequency in combination with the vibration amplitude and the tilt angle of the feeding bowl.
4. Find the optimal frequency: Continue adjusting until the best feeding efficiency is achieved (material moves steadily, continuously, without splashing out or jamming).
5. Notes: Record the optimum vibration frequency for each material and operating condition for future use.

Tips and notes when adjusting vibration frequency

Adjusting the vibration frequency of a vibrating feeder needs to be done carefully to ensure safety and efficiency. Here are some important tips and notes:

Safety first

• Power off: Always disconnect the power supply before performing any operation on the vibrating feeder, including adjusting the vibration frequency. This helps prevent electric shock accidents.

Adjust slowly

• Look closely: When increasing or decreasing the vibration frequency, do it in small steps and observe the flow of material in the feed bowl.
• Avoid sudden adjustments: Sudden changes in vibration frequency can cause strong vibrations, affecting the stability of the machine and possibly damaging the equipment or materials.

Keep clean

• Clean the feeding bowl: Make sure the vibrating feed bowl is clean before operation. Dirt and debris can clog or damage the equipment.

Take careful notes

• Save parameters: Once you have found the appropriate vibration frequency for each material, record these parameters for future use.
• Save time: Recording saves time on adjustments and ensures consistency in the production process.

Conclude

Vibration frequency is an important factor affecting the performance of the vibrating feeder. Determining and adjusting the vibration frequency to suit each type of material and production requirements will help optimize the feeding efficiency. This improves productivity and product quality.

Remember that testing and adjusting the vibration frequency is necessary to achieve the best feeding effect. By observing and adjusting the vibration frequency, you can ensure that the vibrating feeder operates stably, continuously and efficiently.
