As a type of bulk materials feeder, the vibrating feeder is widely used in industries such as food, mining, coal, and building materials for the transportation of bulk raw materials due to its advantages such as high efficiency, low noise, anti - clogging, adjustable amplitude/frequency, and maintenance - free.

To improve the production efficiency of the factory using the vibrating feeder, first of all, we need to understand the structure of the vibrating feeder. After clearly sorting out our own needs, we can get a customized vibrating feeder.

The structure of the vibrating feeder is very simple, mainly composed of a vibrating motor, a conveying trough/pipe, a vibration - exciting frame, supports, springs, liners, etc. To determine whether a vibrating feeder is of good quality, the most important thing is to look at the selection and design of the vibrating motor and the vibration - exciting frame. The vibrating feeder manufacturer needs to calculate based on parameters such as the handling capacity, bulk density, and size of the bulk materials to select a suitable vibrating motor and design the angle, length, etc. of the vibration - exciting frame.

Vibrating Motor

The vibrating motor is the power core of the vibrating feeder. It usually adopts a double - output - shaft eccentric block structure. By adjusting the angle between the eccentric blocks, the magnitude of the exciting force can be changed. After being powered on, it drives the equipment to generate directional vibration, thereby propelling the materials to move forward along the trough. Its rotational speed and exciting force parameters directly determine the conveying efficiency and amplitude stability of the feeder.

Conveying Trough / Pipe

The conveying trough (or conveying pipe) is the material - carrying and conveying channel of the vibrating feeder. The trough body mostly has a trough - shaped or plate - shaped structure, while pipes are suitable for the closed - conveying scenarios of powders and small particles. Its shape, length, and inclination angle need to be designed according to the material characteristics and conveying requirements. During operation, it reciprocates with the vibration system, and realizes continuous conveying by means of the throwing or sliding of the materials. Some trough bodies are designed to be segmented for easy installation and maintenance.

Vibration - exciting Frame

The vibration - exciting frame is the force - transmission and connection component of the vibrating feeder. It is generally rigidly connected to the vibrating motor and the conveying trough. Its function is to evenly transmit the exciting force generated by the vibrating motor to all parts of the conveying trough, ensuring that the entire trough body vibrates synchronously and avoiding local stress concentration. At the same time, it can also play a role in fixing the vibrating motor, ensuring the installation stability of the motor under high - frequency vibration conditions.

Support

The support is the support and installation foundation of the vibrating feeder. It is mainly used to fix the equipment on the foundation or frame. Its structural form needs to match the overall weight and vibration characteristics of the feeder. It is usually designed as a welded steel or cast - steel structure, having sufficient strength and stiffness to withstand the dynamic load during the operation of the equipment. Some supports can also adjust the height and inclination angle to meet different installation and conveying requirements.

Spring

The spring is a key component for vibration isolation and buffering of the vibrating feeder. It is installed between the support and the vibration - exciting frame (or conveying trough), and is mainly divided into types such as spiral springs and rubber springs. During operation, the spring can not only support the self - weight of the equipment, but also absorb vibration energy, reduce the transmission of equipment vibration to the foundation, prevent resonance from occurring, and at the same time, through its own elastic deformation, assist in maintaining the stable amplitude of the vibration system.

Liner

The liner is a protective and wear - resistant component laid on the inner wall of the conveying trough. Its materials are mostly wear - resistant steel plates, polyurethane, rubber, and other wear - resistant and impact - resistant materials. Its function is to protect the conveying trough body from the direct scouring and wear of the materials, and extend the service life of the trough body. In addition, liners of different materials can also adjust the friction coefficient between the materials and the trough body, optimize the conveying speed and fluidity of the materials, and prevent the materials from adhering to the trough wall.
