TECHNICAL FIELD
[0001] The present application relates to the technical field of magnetic sorting mechanism, in particular to a continuous magnetic sorting mechanism. BACKGROUND
[0002] In the material sorting technical field of the present application, the continuous mesh belt sintering furnace is the core equipment for batch production of magnetic materials, and is one of the key links in the production process. It is to efficiently separate the magnetic products attached to the stainless steel mesh belt of the sintering furnace after sintering from the mesh belt and transfer them to the subsequent processing or collection station to ensure the continuity of production and product quality.
[0003] Most enterprises still adopt manual material collection mode. The operator needs to continuously stand by at the tail of the sintering furnace and use a shovel plate to shovel the products on the stainless steel mesh belt one by one. This mode not only has high labor intensity and low single operation efficiency, resulting in high production cost, but also, more importantly, the rigid contact between the shovel plate and the product can easily cause appearance damage such as corner impact and surface scratching of the product. Especially for precise magnetic components, the damage rate can reach 5%-10%, which seriously affects the product quality stability and increases the cost of rework of defective products.
[0004] Some enterprises try to replace manual operation with simple magnetic sorting mechanism. However, such mechanisms generally have design defects. The pressure detection link is missing or too rigid. Some mechanisms do not have product height detection components and directly rely on preset parameters for operation, which has poor adaptability. A few mechanisms with detection function use metal pressure detection components, which can easily scratch the product surface and still cannot avoid quality risks. SUMMARY

[0021] Please see Figures 1-5This invention provides a technical solution: a continuous magnetic sorting mechanism, comprising a fixed frame 1, a fully magnetic active roller 2, and a non-magnetic active roller 10. The fully magnetic active roller 2 is mounted at one end of the fixed frame 1, and the non-magnetic active roller 10 is mounted at the other end. A magnetic roller conveyor belt 6 surrounds the outer sides of the fully magnetic active roller 2 and the non-magnetic active roller 10. A connecting magnetic attraction device 13 is installed on the fixed frame 1 between the fully magnetic active roller 2 and the non-magnetic active roller 10. The inner corners of the fixed frame 1 are mounted on a frame 9 via lifting and adjusting components 8, and the fixed frame 1 is fixed by supports. There is a magnetic roller drive device 7, which drives the fully magnetic active roller 2 to rotate through the transmission component 15. A pressure testing device 5 is installed at the end of the fixed frame 1 on the outer side of the fully magnetic active roller 2. The sintering furnace stainless steel mesh belt 4 is located below the fully magnetic active roller 2 and the pressure testing device 5. The sintering furnace stainless steel mesh belt 4 is installed on the main frame 3 of the tail of the sintering furnace. A transfer conveyor belt 12 is set below the non-magnetic active roller 10. The non-magnetic active roller 10 is slidably adjusted at one end of the magnetic attraction device 13 by the tension adjustment frame 11. A tension adjustment component 14 is installed on the tension adjustment frame 11. The pressure testing device 5 includes a pressure testing device mounting frame 501 mounted on a fixed frame 1, four sets of pressure testing adjustment telescopic rods 503 passing through the pressure testing device mounting frame 501, and a pressure testing rubber roller 510 mounted on the lower end of the pressure testing adjustment telescopic rod 503 via a pressure testing wheel axle 509. A telescopic rod synchronous connecting rod 506 is fixed to the upper end of the pressure testing adjustment telescopic rod 503. A return spring 504 is provided between two adjacent sets of pressure testing adjustment telescopic rods 503. The two ends of the return spring 504 are hung on spring fixing hooks 505 on the pressure testing device mounting frame 501 and the telescopic rod synchronous connecting rod 506. A pressure testing position sensor 508 is mounted on the outside of the return spring 504 via a support. A pressure testing position contact plate 507 is fixed on the telescopic rod synchronous connecting rod 506 corresponding to the position of the pressure testing position sensor 508.
[0022] The pressure testing device mounting bracket 501 has a pressure testing adjustment telescopic rod 503 fixed on its outer side, and a pressure testing telescopic limit ring 502 is fixed on the rod. The spring fixing hook 505 on the pressure testing device mounting bracket 501 is an adjustable height structure.
[0023] The tension adjustment assembly 14 includes bearing seats 1401 mounted on the shafts at both ends of the non-magnetic drive roller 10, and an adjustment slider 1402 fixed below the bearing seats 1401. The adjustment slider 1402 is slidably mounted on the slide rail 1403, and a nut is fixed in the groove at the end of the slide rail 1403. A fine adjustment screw 1404 is screwed into the nut, and the end of the fine adjustment screw 1404 is rotatably connected to the adjustment slider 1402.
[0024] The pressure testing rubber roller 510 is made of soft, wear-resistant silicone rubber, and the outer circumferential surface of the pressure testing rubber roller 510 is provided with anti-slip and wear-resistant texture.
[0025] The transmission assembly 15 includes a driven synchronous pulley fixed to the shaft end of the fully magnetic drive roller 2, a drive synchronous pulley fixed to the output shaft of the magnetic roller drive device 7, and a synchronous belt sleeved on the outside of the drive synchronous pulley and the driven synchronous pulley. The transmission ratio between the drive synchronous pulley and the driven synchronous pulley is 1:1 to 1:3, and the inner circumferential surface of the synchronous belt is provided with meshing teeth that are adapted to the tooth grooves of the pulleys.
[0026] The lifting adjustment assembly 8 adopts either a worm gear lifting adjustment mechanism or a turnbuckle. The worm gear lifting adjustment mechanism includes a worm, a worm wheel meshing with the worm, and an adjustment handwheel that drives the worm to rotate.
[0027] The spring-loaded fixing hook 505 is threadedly connected to the pressure testing device fixing frame 501 and the telescopic rod synchronous connecting rod 506 via external threads. The hook has height scale lines engraved on its outer side, and its height adjustment range is 0-50mm. The hook end of the spring-loaded fixing hook 505 is equipped with an anti-disengagement buckle.
[0028] The pressure position sensor 508 is a contact displacement sensor. The initial gap between the pressure position sensor 508 and the pressure position contact plate 507 is 1-3mm. The signal output terminal of the pressure position sensor 508 is electrically connected to the external control system through a wire to provide feedback on the height detection signal.
[0029] The connecting magnetic suction device 13 is made of permanent magnet splicing, and the connecting magnetic suction device 13 is detachably connected to the fixed frame 1 by bolts. The distance between the side of the connecting magnetic suction device 13 facing the magnetic roller conveyor belt 6 and the outer surface of the magnetic roller conveyor belt 6 is 5-15mm. At the same time, the length of the connecting magnetic suction device 13 is adapted to the width of the magnetic roller conveyor belt 6.
[0030] Before practical application, the pre-adjustment of the mechanism needs to be completed: Adjust the overall height of the fixed frame 1 by adjusting the lifting and adjusting component 8. If a worm gear lifting and adjusting mechanism is used, rotate the adjusting handwheel to drive the worm gear to rotate, thereby realizing the extension and retraction of the lifting and adjusting component 8. If a turnbuckle is used, adjust the length directly by turning the turnbuckle to ensure that the initial gap between the magnetic roller conveyor belt 6 and the sintering furnace stainless steel mesh belt 4 is properly matched. Adjust the preload of the return spring 504 by adjusting the spring fixing hook 505. According to the product specifications, refer to the height scale line on the outside of the hook and screw the spring fixing hook 505 to the corresponding height. The anti-disengagement buckle at the end of the hook can prevent the return spring 504 from falling off. At the same time, the pressure test telescopic limit ring 502 limits the pressure test adjustment. The maximum extension stroke of the telescopic rod 503 is controlled to prevent excessive extension and contraction from damaging components. The tension of the magnetic roller conveyor belt 6 is adjusted by using the tension adjustment component 14. The fine-tuning screw 1404 is rotated to drive the adjusting slider 1402 to slide along the slide rail 1403, thereby moving the bearing seats 1401 at both ends of the non-magnetic drive roller 10. This allows for fine-tuning of the distance between the non-magnetic drive roller 10 and the fully magnetic drive roller 2, ensuring that the tension of the magnetic roller conveyor belt 6 is appropriate and preventing slippage or excessive stretching during operation. In addition, the initial gap between the pressure position sensor 508 and the pressure position contact plate 507 is calibrated to maintain it at 1-3mm. At the same time, a stable electrical connection is established between the pressure position sensor 508 and the external control system to ensure real-time signal transmission.
[0031] During normal operation, the products to be sorted are continuously conveyed by the sintering furnace stainless steel mesh belt 4. Before entering the area covered by the magnetic roller conveyor belt 6, the guide guard plate on the side of the discharge section of the sintering furnace stainless steel mesh belt 4 first guides and limits the products to prevent them from deviating from the preset track due to conveying deviation. When the products are conveyed to the bottom of the pressure testing device 5, the pressure testing rubber roller 510 first contacts the upper surface of the products. Since the pressure testing rubber roller 510 is made of soft wear-resistant silicone rubber and has anti-slip and wear-resistant texture on its outer circumference, it can ensure stable contact with the products and avoid scratches or impacts to the product's appearance. The height of the products will push the pressure testing rubber roller 510 to move upward, which in turn drives the pressure testing adjustment telescopic rod 503 to extend and retract upward along the pressure testing device fixing frame 501. The telescopic rod synchronous connecting rod 506 moves synchronously with the pressure testing adjustment telescopic rod 503, causing the return spring 504 to be stretched.
[0032] During this process, the pressure testing position contact plate 507 moves synchronously with the telescopic rod and the connecting rod 506. When the pressure testing position contact plate 507 contacts the pressure testing position sensor 508, the pressure testing position sensor 508 immediately sends a detection signal to the external control system. Based on the product height data fed back by the signal, the external control system drives the lifting adjustment component 8 to make precise fine adjustments, further optimizing the distance between the magnetic roller conveyor belt 6 and the product, and ensuring that the magnetic adsorption effect reaches the best.
[0033] The magnetic roller drive device 7 starts, driving the fully magnetic drive roller 2 to rotate via the transmission assembly 15. The active synchronous pulley in the transmission assembly 15 rotates with the output shaft of the magnetic roller drive device 7, and drives the driven synchronous pulley to rotate via the synchronous belt meshing transmission, ensuring that the magnetic roller conveyor belt 6 runs smoothly at the preset speed. When the fully magnetic drive roller 2 rotates, it drives the magnetic roller conveyor belt 6 to rotate. Under the magnetic action of the fully magnetic drive roller 2, the magnetic roller conveyor belt 6 obtains an adsorption force, adsorbing and separating the product from the stainless steel mesh belt 4 of the sintering furnace, realizing the initial separation of the product from the turnover equipment.
[0034] When the magnetic roller conveyor belt 6, which carries the product, moves to the area of the connecting magnetic attraction device 13, the connecting magnetic attraction device 13 uses the magnetic field formed by the splicing of permanent magnets to guide the product for secondary adsorption. The side of the connecting magnetic roller conveyor belt 6 is kept 5-15mm away from the outer surface of the magnetic roller conveyor belt 6, and its length is adapted to the width of the magnetic roller conveyor belt 6 to ensure that the product does not fall off or deviate during the transfer process. As the magnetic roller conveyor belt 6 continues to move, when the product moves to the area corresponding to the non-magnetic drive roller 10, since the non-magnetic drive roller 2 is non-magnetic, the product loses its adsorption force and falls smoothly onto the transfer conveyor belt 12 below under the action of gravity, completing the final separation and transfer of the product. The transfer conveyor belt 12 transports the product to the subsequent processing or collection station. The whole process is continuous and uninterrupted, realizing the efficient sorting of magnetic materials.
[0035] During operation, the reset spring 504 always provides a reset force to the pressure testing adjustment telescopic rod 503. When the product is removed from the pressure testing rubber roller 510, the reset spring 504 retracts, driving the pressure testing adjustment telescopic rod 503 and the pressure testing rubber roller 510 to reset, waiting for the next batch of products to be tested, ensuring that the pressure testing device 5 continues to work stably.
