Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic product processing, and more specifically relates to an automatic screening and feeding device for magnetic products. Background Art

[0002] The automatic screening and feeding device is used to screen magnetic products (such as nails) in abrasives. The automatic screening and feeding device consists of a frame, a strong magnetic roller, a driving roller, a motor group, a conveyor, a feed hopper, a discharge plate and a conveyor belt. When the automatic screening and feeding device screens nails in abrasives, the material is poured into the feed hopper and falls into the conveyor. When the conveyor starts, it drives the material to move to the strong magnetic roller. Since the nails are magnetically adsorbed by the strong magnetic roller, they are separated from the abrasive and then fall into the collection bucket from the end of the conveyor. The motor drives the driving roller to rotate, thereby driving the conveyor belt to rotate, causing the strong magnetic roller to rotate, so that the nails follow the conveyor belt and fall into the discharge plate from the end of the driving roller, thereby completing the automatic screening of nails and abrasives.

[0003] The inventor discovered in his daily work that when the automatic screening and feeding device is in use, the nails are separated from the abrasive due to the magnetic adsorption of the strong magnetic roller. When the strong magnetic roller adsorbs the nails, the nails may be magnetized, making them magnetic, which may cause the nails to be adsorbed together, which may indirectly lead to disadvantages for subsequent processing of the nails.
