[0001] This utility model relates to the field of waste metal processing technology, specifically to a waste metal recycling device. Background Technology
[0002] Scrap metal recycling equipment is a key piece of equipment used to process various types of scrap metal and achieve resource reuse. It transforms scrap metal into reprocessable raw materials through a series of processes. Common equipment includes crushers, which break large pieces of scrap metal into smaller pieces for easier subsequent processing; magnetic separators, which separate ferromagnetic metals based on their magnetic differences; and eddy current separators, which separate non-ferromagnetic metals such as copper and aluminum.
[0003] In traditional scrap metal recycling operations, due to the varying textures and shapes of scrap metal, metal fragments are easily stuck in the roller gaps during crushing, hindering the normal operation of the crushing rollers, causing the crushing process to be interrupted, and significantly reducing efficiency. This not only affects crushing efficiency but may also exacerbate roller surface wear, shorten equipment life, and increase maintenance costs. Therefore, a scrap metal recycling device is proposed. Summary of the Invention

[0023] As shown in Figures 1 to 4, a scrap metal recycling device includes a crushing box 1, which is a hollow rectangular box. A feed funnel 2 is fixedly installed on the top of the crushing box 1. Two crushing rollers 3 are movably installed inside the crushing box 1. Two servo motors 4 for driving the two crushing rollers 3 to rotate are fixedly installed on the rear wall of the crushing box 1. A screen 5 is fixedly installed in the crushing box 1. Discharge ports 6 are opened on the left and right sides of the crushing box 1. Two brushes 7 are arranged inside the crushing box 1. Two sets of telescopic rod assemblies 8 are arranged at the bottom of each brush 7. A transmission assembly 9 for driving the corresponding two sets of telescopic rod assemblies 8 to extend and retract is arranged below each brush 7. A flattening assembly 10 for pre-compressing the scrap metal is arranged on the top of the crushing box 1. It should be noted that the scrap metal is first fed through the feed funnel 2. The scrap metal is fed into the crushing chamber 1, and two servo motors 4 are simultaneously activated to drive the two crushing rollers 3 to rotate, causing the two crushing rollers 3 to rotate in opposite directions. When the scrap metal passes between the two crushing rollers 3, it will be crushed into metal fragments. To prevent the metal fragments from adhering to the surface of the crushing rollers 3, two sets of transmission components 9 are activated at the same time, causing the two sets of transmission components 9 to drive the corresponding two sets of telescopic rod components 8 to extend and retract, so that the two brushes 7 continuously contact the surface of the adjacent crushing rollers 3. The brushes 7 are used to sweep away the metal fragments adhering to the surface of the crushing rollers 3. To further improve the crushing efficiency, when the scrap metal is fed into the crushing chamber 1 through the feed funnel 2, the flattening component 10 can be used to flatten the scrap metal, so that the scrap metal can be more easily crushed into metal fragments between the two crushing rollers 3.
[0024] The telescopic rod assembly 8 includes mounting rods 801. Two mounting rods 801 are fixedly installed on the inner walls of the left and right sides of the crushing box 1, respectively. A cylinder 802 is fixedly installed on the top of each mounting rod 801. A movable rod 803 is movably installed inside each cylinder 802. The top of each movable rod 803 is fixedly connected to an adjacent brush 7. A spring 804 is fixedly installed at the bottom of each movable rod 803. Each spring 804 is fixedly installed inside the corresponding mounting rod 801. It should be noted that, due to the telescopic properties of the spring 804, when the brush 7 is pushed close to the adjacent crushing roller 3, the brush 7 will drive the two movable rods 803 connected to it to move synchronously. Each movable rod 803 will drive the corresponding spring 804 to stretch. When the force pushing the brush 7 disappears, the spring 804 will contract and drive the corresponding movable rod 803 and the brush 7 away from the adjacent crushing roller 3.
[0025] The transmission assembly 9 includes an actuator motor 901. Two actuator motors 901 are fixedly installed on the rear wall of the crushing box 1. The output end of each actuator motor 901 extends into the interior of the crushing box 1 and is fixedly connected to a gear 902. A rotating shaft 903 is movably installed between each pair of adjacent mounting rods 801. A cam 904 is fixedly installed on each rotating shaft 903. A gear 905 is fixedly installed on each rotating shaft 903. Each gear 905 meshes with the adjacent gear 902. It should be noted that by starting the actuator motor 901, the actuator motor 901 can drive the gear 902 to rotate. The gear 902 can drive the corresponding gear 905 to rotate. The gear 905 can drive the corresponding rotating shaft 903 and cam 904 to rotate. During the rotation, the cam 904 can continuously push the brush 7 towards the adjacent crushing roller 3.
[0026] The flattening assembly 10 includes vertical rods 1001. Two vertical rods 1001 are provided on the top of the crushing box 1. Hydraulic rods 1002 are fixedly installed on the side of the two vertical rods 1001 that are close to each other. A pressing plate 1003 is fixedly installed at the output end of each hydraulic rod 1002. It should be noted that the scrap metal is placed between the two pressing plates 1003, and then the two hydraulic rods 1002 are activated, so that the two pressing plates 1003 gradually move closer to flatten the scrap metal in the middle.
[0027] The flattening assembly 10 also includes connecting blocks 1004. Four connecting blocks 1004 are fixedly installed on the top of the crushing box 1. Each vertical rod 1001 has a threaded hole 1005 on its side wall. The two connecting blocks 1004 on the front side have tapping holes 1006 on their side walls, and the two connecting blocks 1004 on the rear side have threaded grooves 1007 on their side walls. Each threaded groove 1007 is connected to the adjacent tapping hole 1006 and threaded hole 1005 by a bolt 1008. It should be noted that if it is not necessary to flatten the scrap metal, the two bolts 1008 can be rotated to disengage each bolt 1008 from the corresponding threaded hole 1005, tapping hole 1006, and threaded groove 1007, thereby removing the two vertical rods 1001 from the top of the crushing box 1.
[0028] The screen 5 is inclined downward from right to left, and the inner bottom surface of the crushing box 1 is inclined downward from left to right. It should be noted that larger metal fragments will stay on the surface of the screen 5, slide down from high to low and be discharged from the corresponding discharge port 6, while smaller metal fragments will stay on the inner bottom surface of the crushing box 1, slide down from high to low and be discharged from the corresponding discharge port 6.
[0029] In summary:
[0030] First, scrap metal is fed into the crushing box 1 through the feeding hopper 2, and two servo motors 4 are started simultaneously to drive two crushing rollers 3 to rotate, so that the two crushing rollers 3 rotate in opposite directions. When the scrap metal passes between the two crushing rollers 3, it will be crushed into metal fragments. To prevent metal fragments from adhering to the surface of the crushing rollers 3, two sets of transmission components 9 are started simultaneously, so that the two sets of transmission components 9 drive the corresponding two sets of telescopic rod components 8 to extend and retract, so that the two brushes 7 continuously contact the surface of the adjacent crushing rollers 3, and use the brushes 7 to sweep away the metal fragments adhering to the surface of the crushing rollers 3. To further improve the crushing efficiency, when the scrap metal is fed into the crushing box 1 through the feeding hopper 2, the flattening component 10 can be used to flatten the scrap metal, so that the scrap metal can be more easily crushed into metal fragments between the two crushing rollers 3.
