Technical Field

[0001] The utility model relates to the technical field of automatic parts feeding systems, in particular to a servo automatic feeding bin. Background Art

[0002] In an automated production line, the feeding silo is one of the key devices to ensure production continuity and stability. At present, there are many feeding silos on the market, most of which use mechanical or pneumatic feeding methods. However, these existing technical solutions have shortcomings in feeding accuracy, response speed, and material adaptability. Especially when the material properties change greatly or the feeding amount needs to be precisely controlled, the existing technology often cannot meet the production needs.

[0003] Specifically, mechanical feeding silos usually feed materials through a motor-driven screw conveyor mechanism, but their feeding accuracy is greatly affected by the wear of the screw conveyor mechanism, and their response speed is slow, making it difficult to adapt to rapidly changing production needs. Although pneumatic feeding silos have a faster response speed, their feeding accuracy is greatly affected by air pressure fluctuations, and they have certain requirements on the properties of the materials, and their adaptability is poor, so we need a servo automatic feeding silo to solve the above problems.

Two sets of long racks and slide rails are provided on the back of the main frame to match them. When the servo motor is started, it drives the reducer to operate, thereby further driving the gears to operate, so that the entire mechanism can move up and down along the guide rail.
