Plastic particle detection device

The utility model provides a plastic particle detection device which comprises a main body mechanism which comprises a placing plate and a collecting box arranged on one side of the placing plate, the adsorption mechanism comprises a supporting plate arranged at the top of the placing plate, a top plate arranged at one end of the supporting plate, a linear sliding rail arranged at the bottom of the top plate, a hydraulic cylinder arranged at the bottom of the linear sliding rail, an electromagnet plate arranged at the bottom of the hydraulic cylinder and a metal plate arranged at the bottom of the electromagnet plate; when the plastic particle collecting device is used, the hydraulic cylinder drives the electromagnet plate to move downwards, after a metal plate at the bottom of the electromagnet plate makes contact with plastic particles at the top of the containing plate, the plastic particles with metal chippings are adsorbed and then lifted, the linear sliding rail drives the plastic particles with the met
