The inside of the movable seat 707 is located at the outer wall of the first spur gear 711 and is slidably connected to a tooth block 712. The top of the movable seat 707 is rotatably connected to a rotating disk 714. The bottom end of the rotating disk 714 is fixedly connected to a first threaded rod 713. The first threaded rod 713 extends to the inside of the tooth block 712. The shielding mechanism 8 includes a transverse groove 801, which is opened on the outer wall of the guide frame 702. The inner wall of 801 is slidably connected with a horizontal plate 802, the inside of the guide frame 702 is slidably connected with an extrusion block 803 extending to the inner cavity of the horizontal groove 801, a first spring 804 is connected between the extrusion block 803 and the guide frame 702, the inner part of the guide frame 702 is located on the outer wall of the extrusion block 803 and is rotatably connected with a second gear 805, the inner part of the guide frame 702 is located on the outer wall of the second gear 805 and is slidably connected with an insertion block 806, the bottom end of the insertion block 806 extends to the bottom of the guide frame 702, a slot 807 for inserting the insertion block 806 is opened at the top of the collection box 701, and the horizontal plate 802 is fixed to the inner wall of the horizontal groove 801 by the mounting mechanism 9.

[0031] In this embodiment: when collecting materials, the materials move along the conveyor 2, and non-magnetic materials fall directly from the magnetic roller 3. The magnetic materials are attracted by the magnetic roller 3 and move to the magnetic plate 6 until they are separated from the magnetic plate 6 and fall down. The materials pass through the guide frame 702 and fall into the collection box 701 for collection. When the materials in the collection box 701 are processed, the cross plate 802 is inserted into the cross groove 801, and the cross plate 802 blocks the inner cavity of the guide frame 702. The materials fall on the cross plate 802 for temporary collection. At the same time, the cross plate 802 contacts the extrusion block 803, pushing the extrusion block 803 to move, causing the first spring 804 to be squeezed. The movement of the extrusion block 803 drives the second gear 805 to rotate, and the rotation of the second gear 805 drives the insertion block 806 to move out of the slot 807, canceling the fixation of the collection box 701.

[0032] At this time, the second motor 705 can be started, and the second motor 705 drives the screw rod 706 to rotate. The screw rod 706 rotates to drive the movable seat 707 to slide in the movable groove 704. The movable seat 707 moves through the groove 708 to drive the collection box 701 to move, and the collection box 701 is separated from the guide frame 702 until the movable seat 707 moves to one end of the movable groove 704.

The tooth block 712 moves to drive the first spur gear 711 to rotate, and the first spur gear 711 rotates to drive the connecting shaft 710 to rotate. The connecting shaft 710 rotates to drive the positioning plate 709 to rotate. The positioning plate 709 rotates and separates from the collection box 701, so that the collection box 701 can slide out of the opening of the slide groove 703 without lifting the collection box 701.

[0033] When the material in the collection box 701 is processed, the collection box 701 is placed in the slide groove 703, located on one side of the movable seat 707.

The movement of the movable seat 707 drives the collection box 701 to move to the bottom of the guide frame 702. At this time, the cross plate 802 can be moved out of the cross groove 801, and the material temporarily collected at the top of the cross plate 802 falls into the collection box 701 for collection. At the same time, the extrusion block 803 is reset by the elastic force of the first spring 804. The resetting of the extrusion block 803 drives the second gear 805 to rotate. The rotation of the second gear 805 drives the insertion block 806 to insert into the slot 807, thereby fixing the collection box 701 to prevent the collection box 701 from loosening during the collection process, resulting in waste of materials, and facilitating the cleaning operation of the collection box 701 without stopping the machine.
