The driving motor 28 is started, and its output end rotates, and the rotating rod 29 is driven to rotate through the pulley mechanism 30, thereby driving the driving wheel 32 to rotate through friction, thereby driving the driven wheel 33 pressed against the driving wheel 32 to rotate, and then driving the connecting shaft 22 to rotate. At this time, the ratchet 24 on the connecting shaft 22 and the ratchet 25 on the gear 23 are engaged and separated.

When the connecting shaft 22 rotates, it drives the electro-magnetic roller 17 to rotate, and the surface of the rotating electro-magnetic roller 17 is cleaned by the cleaning brush 35.

[0032] Principle of the present invention: When in use, the cutting mechanism 3 is slidably arranged on the gantry 2, and the metal sheet on the conveying roller mechanism is cut by the cutting mechanism 3; The electrically controlled magnet roller 17 is energized to have magnetic attraction, and the drive motor 18 is started, which drives the reciprocating screw 19 to rotate, and then drives the screw sleeve 20 to move, drives the connecting shaft 22 to move, drives the gear 23 to move, and with the assistance of the rack 21, the moving gear 23 rotates, and then drives the pawl 25 to rotate, and then drives the ratchet 24 engaged with the pawl 25 to rotate, and then drives the connecting shaft 22 to rotate, so that the connecting shaft 22 rotates and moves, and then drives the electrically controlled magnet roller 17 fixedly connected to the connecting shaft 22 to rotate while moving, and the energized electrically controlled The magnet roller 17 adsorbs the metal waste particles to its surface and adsorbs them relatively evenly to avoid aggregation. When the electro-magnetic roller 17 moves back to the cleaning mechanism 11 (during the movement of the electro-magnetic roller 17, the pawl 25 and the ratchet wheel 24 are separated from each other and will not drive the electro-magnetic roller 17 to rotate at a uniform speed), the drive motor 18 stops running at the end of the frame 1, the electro-magnetic roller 17 is powered off, and the adsorbed metal waste particles fall to the end of the platen of the frame 1, so that the metal waste particles are cleaned out from the deeper part of the frame 1, which is convenient for cleaning. When the connecting shaft 22 is displaced, the fixed plate 14 is driven to move, and the annular protection belt 13 is driven to fit the rotating rod 12 to perform annular motion. The upper and lower ends of the annular protection belt 13 fit the upper and lower end surfaces of the placement groove 9, and the placement groove 9 is closed to prevent metal waste particles from entering the reciprocating screw 19 and the screw sleeve 20, thereby avoiding affecting the operation of the reciprocating screw 19 and the screw sleeve 20; To ensure the cleanliness of the electro-magnetic roller 17, the electro-magnetic roller 17 moves to the cleaning mechanism 11 and the power is cut off. At this time, the driven wheel 33 presses against the driving wheel 32, and the driving motor 28 is started, and its output end rotates, and the rotating rod 29 is driven to rotate through the pulley mechanism 30, thereby driving the driving wheel 32 to rotate. Through the friction force, the driven wheel 33 pressed against the driving wheel 32 is driven to rotate, and then the connecting shaft 22 is driven to rotate. At this time, the ratchet 24 on the connecting shaft 22 and the ratchet 25 on the gear 23 are engaged and separated. Therefore, there will be no conflict and jamming with the stopped displacement mechanism 15. When the connecting shaft 22 rotates, it drives the electro-magnetic roller 17 to rotate, and the surface of the rotating electro-magnetic roller 17 is cleaned by the cleaning brush 35.

Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the authorization requirements.
