The self-checking component includes an automatic iron detection sensor and a controller. The signal output terminal of the automatic iron detection sensor is electrically connected to the controller, and the controller is electrically connected to the drive power unit of the scrap iron conveyor belt.

Several baffles are fixedly connected at equal intervals to the outside of the belt 9. 15; Side frame 3, which is fixedly connected to the outside of one side of the frame 1. A drive mechanism is provided on one side of the side frame 3. The drive mechanism includes a transmission box 10 fixedly connected to the outside of the side frame 3 and one side of the frame 1, and a motor 11 fixedly connected to the top of the side frame 3. Three coaxially fixed synchronous pulleys 12 are rotatably connected to the right side of the inside of the transmission box 10 through bearings. A synchronous pulley 13 is rotatably connected to the left side of the inside of the transmission box 10 through bearings. The output shaft of the motor 11 is fixedly connected to the synchronous pulley 13. The synchronous pulley 13 and the synchronous pulleys 12 on the same side are connected by synchronous belt drive. A synchronous pulley 14 is fixedly connected to one end of the driven roller 7. The synchronous pulley 14 and the synchronous belt on the same side are connected by synchronous belt drive. Wheel 12 is connected via synchronous belt drive; a cleaning mechanism is provided on the side of the frame 1 near the side frame 3. The cleaning mechanism includes a brush roller 16 located on the side of the frame 1 near the side frame 3, and a connecting shaft 27 rotatably connected to the end of the frame 1 near the transmission box 10 via bearings. A synchronous belt pulley 28 is fixedly connected to the end of the connecting shaft 27 away from the brush roller 16. The synchronous belt pulley 28 and the synchronous belt pulley 12 on the same side are connected via synchronous belt drive. The brush roller 16 is in rolling contact with the belt 9. The drive mechanism cooperates with the cleaning mechanism and the rolling mechanism. A positioning plate 17 is fixedly connected to the end of the connecting shaft 27 away from the synchronous belt pulley 12. A rectangular section is opened in the middle of the end of the positioning plate 17 away from the connecting shaft 27. The end of the brush roller 16 near the positioning plate 17 is fixedly connected to the slot 18, and a rectangular insert 19 matching the rectangular slot 18 is fixedly connected to the end of the frame 1 away from the connecting shaft 27. A screw 20 is internally threaded to the end of the frame 1 away from the connecting shaft 27.

This completely solves the technical problem that the spring mechanism in traditional iron removers is easily blocked and jammed by iron filings, resulting in malfunction. This ensures the long-term reliability of the cleaning mechanism.

[0014] Furthermore, by adopting an arrangement in which the brush roller 16 rolls in contact with the surface of the belt 9, and by utilizing the characteristic of the brush bristles naturally bending when the baffle 15 passes by, the residual iron impurities on the working surface of the belt 9 and the side of the baffle 15 are cleaned simultaneously, which significantly improves the iron removal efficiency and cleaning effect, and solves the technical defect of the existing equipment that does not clean the baffle 15 properly.

[0015] Working principle: After the motor 11 starts, it drives the synchronous pulley 13 on its output shaft to rotate. The synchronous pulley 13 drives the synchronous pulley 12 located on the right side inside the transmission box 10 to rotate via a synchronous belt. The synchronous pulley 12 group, which is coaxially fixed, rotates as a whole. The synchronous pulley 12 group drives the synchronous pulley 14 fixed to one end of the driven drum 7 to rotate via another synchronous belt, thereby driving the driven drum 7 to rotate. On the other hand, it also drives the synchronous pulley 28 fixed to one end of the connecting shaft 27 to rotate via a synchronous belt. The rotational power of the driven drum 7... The material is transmitted to the drive drum 6 via belt 9, causing belt 9, which is wrapped around drive drum 6, driven drum 7, and two guide rollers 8, to begin circulating. When material containing iron impurities passes through the area of ​​belt 9 above frame 1, the strong magnetic field generated by permanent magnet 2 attracts the iron impurities to the surface of belt 9. These impurities are then blocked by the equally spaced and fixed baffles 15, moving along with belt 9. When belt 9 carrying iron impurities moves to an area far from the effective range of the permanent magnet 2's magnetic force, the magnetically attracted iron impurities fall off smoothly under gravity. Simultaneously, the synchronous pulley 28... The rotation drives the connecting shaft 27 to rotate. The end of the connecting shaft 27 away from the transmission box 10 engages with the rectangular slot 18 of the positioning plate 17 on it and the rectangular insert 19 at one end of the brush roller 16, transmitting torque to the brush roller 16 and causing it to rotate synchronously. The brush roller 16 maintains rolling contact with the surface of the belt 9. When the baffle 15 on the belt 9 moves to the bristles of the brush roller 16, the bristles naturally bend to pass the baffle 15 and thoroughly remove any residual iron impurities from the baffle 15. When the area of ​​the belt 9 with attached iron impurities reaches the brush roller 16, the rotating brush roller 16... 6. Brush off any remaining iron impurities to complete the cleaning process; the other end of the brush roller 16 is radially positioned by the insertion and engagement of the central groove 25 with the fixed post 23 fixed on the fixed plate 22, and axially limited by the insertion and engagement of the annular groove 26 with the fixed ring 24 on the fixed plate 22. The fixed plate 22 is adjustablely locked on the frame 1 by the screw 20 and the handwheel 21. By rotating the handwheel 21, the screw 20 and the fixed plate 22 can be adjusted to move forward and backward on the frame 1, thereby realizing the assembly and disassembly of the fixed plate 22 and the brush roller 16.

[0016] It should be noted that the brush roller 16 in this technical solution can be a conventional brush roller assembly in the art (such as a nylon brush roller or a composite fiber brush roller). Its specific selection can be conventionally selected and adjusted by those skilled in the art according to the characteristics of the material being processed (such as humidity, particle size, and abrasiveness). This falls within the scope of application of known technology and does not affect the implementation of the core innovation of this solution or the realization of its beneficial effects.

[0017] Furthermore, a telescopic dust cover (not shown in the figure) is fitted at the threaded connection between the screw 20 and the frame 1. This telescopic dust cover has a corrugated pipe structure. One end of the telescopic dust cover is rotatably connected to a sealing disc (not shown in the figure) fixedly fitted onto the screw 20, and the other end is fixedly connected to the mounting surface of the frame 1. This dynamic sealing assembly, consisting of the telescopic dust cover and the sealing disc, is a conventional technical means in this field for sealing components that have both rotation and axial movement. This falls within the scope of known technology and does not affect the implementation of the core innovation of this solution or the realization of its beneficial effects.

[0018] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
