Description

A high-efficiency vibrating feeder

technical field

The utility model relates to the technical field of feeding mechanical equipment, in particular to a high-efficiency vibrating feeder.

Background technique

The vibrating feeder is also called the vibrating feeding machine. In the production process, it can uniformly, regularly and continuously feed the bulk and granular materials from the storage bin to the receiving device. The general vibrating feeder is A relatively complete elastic system with dual-mass directional forced vibration. The whole system works in a low critical resonance state. The electromagnetic exciter is mainly used to drive the tank to reciprocate at a certain inclination to make the material in the tank move along the tank; electromagnetic vibration The feeder has simple structure, easy operation, no lubrication, low power consumption, can evenly adjust the amount of ore feeding, and is generally used for loose materials.

According to the installation method, the vibration feeder can be divided into suspension type and table type; because the suspension type electromagnetic vibration feeder can be directly hung at the discharge port, compared with the table type electromagnetic vibration feeder, its tank volume is small, so it is very convenient. It is suitable for equipment with a small amount of output each time; but in actual use, it is found that since the electromagnetic exciter is located at the tail of the tank, the vibration force generated by the electromagnetic exciter is directly applied to the tail of the tank, causing the head of the tank to be in contact with the tank. The vibration speed at the tail of the tank body is different; when the material is piled on the tank body instantly from the equipment, due to the impact of the material, it is very easy to make the material piled at the tail of the tank body fall out; at the same time, due to the gap between the electromagnetic exciter and the tank body The included angle problem, when vibrating, the vibration force generated by the electromagnetic exciter is divided into horizontal component force and vertical component force, and only the vibration feeding depends on the horizontal component force, so the vibration intensity of the tank is not enough. It makes the conveying efficiency low, and it is easy to cause the material to accumulate in the tank, resulting in inaccurate feeding, and the material cannot be screened.
