The box body 1 is arranged in a cylindrical shape, and the mounting cylinder 2 is fixedly mounted on the inner wall of the box body 1. The mounting cylinder 2 is provided with a plurality of mounting openings 21. The plurality of bar magnets 5 are respectively fixedly mounted in the corresponding mounting openings 21. Two rotating shafts 3 which are parallel to each other are rotatably mounted in the mounting openings 21. An upper roller 31 and a lower roller 32 are respectively fixedly mounted on the two rotating shafts 3. The upper roller 31 and the lower roller 32 are respectively connected to the same transmission shaft 31 and the lower roller 32. The conveyor belt 33 is provided with a plurality of conveyor motors 34, and the rotating shaft 3 located at the top is axially fixedly connected to the output shaft of the corresponding conveyor motor 34, so that the metal adsorbed and separated by the bar magnet 5 can be conveyed upward. The upper roller 31 is provided with a plurality of annular grooves 311, and annular magnets 312 are fixedly installed in the plurality of annular grooves 311, so that the metal on the conveyor belt 33 passing through the upper roller 31 can be adsorbed, thereby ensuring that the metal follows the conveyor. The belt 33 moves to a side close to the inner wall of the box body 1, the feed hopper 11 is fixedly installed on the top of the box body 1 and is connected to the box body 1, a circular opening is opened at the bottom of the box body 1, and a fixing rod 4 is fixedly installed on the inner wall of the feed hopper 11 and the inner wall of the circular opening, a connecting rod 41 is radially fixedly installed on the upper fixing rod 4, a mounting box 42 is fixedly installed on the bottom end of the connecting rod 41, a driving motor 43 is fixedly installed in the mounting box 42, a spiral auger 44 is axially fixedly installed on the output shaft of the driving motor 43, and the spiral auger The bottom end of the dragon 44 is radially rotatably installed on the fixed rod 4 below, which can provide stable support for the driving motor 43 and the spiral auger 44. At the same time, with the cooperation of the driving motor 43 and the spiral auger 44, the PET bottle pieces that have not been discharged from the circular mouth in time after entering the installation cylinder 2 can be flipped upwards, thereby avoiding the inclusion of unseparated metal in the PET bottle pieces. At the same time, when the driving motor 43 rotates in the opposite direction, the auxiliary unloading effect can be achieved. The outer bottom of the box body 1 is provided with discharge ports 12 corresponding to the number of installation ports 21.

[0027] In this embodiment, the longitudinal section of the installation box 42 is conical, which can guide the PET bottle flakes entering the installation cylinder 2 through the feed hopper 11 toward the direction close to the conveyor belt 33, so that the metal in the PET bottle flakes can be better separated with the assistance of the bar magnet 5.
