AI Technical Summary
In the long-term operation of existing feeders, the lubricating oil in the bearings evaporates, causing the oil volume to decrease. This affects the normal lubrication of the bearings, which may lead to overheating, wear, and a decline in equipment performance. Furthermore, the replenishment of lubricating oil is difficult to control, which can easily lead to leakage or increase rotational resistance.
A feeder for easy lubrication is designed. The oil level is observed by an oil level mirror installed outside the bearing housing. The amount of lubricating oil is automatically adjusted by an overflow channel and a micro oil pump. Combined with a filter and a return oil tank, the lubricating oil is kept within the appropriate range to avoid too much or too little.
This system enables proper replenishment of lubricating oil, preventing equipment malfunctions caused by insufficient or excessive oil levels, improving bearing life and feeder stability, and reducing lubricating oil waste and energy consumption.

Description

[0002] The feeder is used for realizing uniform, continuous or intermittent feeding of materials, and is widely applied to conveying or feeding systems of various materials. However, in the long-term and continuous working process of the feeder, the bearing will generate a large amount of heat due to bearing load and friction, so that the temperature of the lubricating oil in the bearing box gradually rises. With the temperature rising, part of the lubricating oil will evaporate, resulting in a decrease in the oil amount of the lubricating oil in the bearing box. The evaporation and reduction of the lubricating oil not only affect the normal lubrication of the bearing, but also may cause the bearing to overheat, wear and even damage due to lack of sufficient lubrication, which not only shortens the service life of the bearing, but also affects the overall performance and stability of the feeder, and further adversely affects the production process.
[0003] In order to ensure the normal operation of the feeder and prolong the service life of the bearing, the operator needs to supplement the lubricating oil in the bearing box from time to time. However, in the actual operation process, it is difficult to grasp the amount of lubricating oil supplement. If the lubricating oil is supplemented too little, the frequency of supplement operation is increased. If too much lubricating oil is supplemented, too much lubricating oil may not only cause the lubricating oil to leak out of the seal of the bearing box, but also increase the rotational resistance of the bearing, affect the normal operation of the bearing, and even affect the overall performance of the feeder.
