Description

Technical Field

[0001] This utility model relates to the field of metal scrap technology, specifically a metal scrap processing device. Background Technology

[0002] Manual collection or simple vacuum cleaners are difficult to handle large-scale processing scenarios, with problems such as insufficient suction and limited capacity. Metal scraps are easily scattered or blown away, leading to environmental pollution and resource waste. They are not effectively separated from metal scraps with high magnetic permeability and strong magnetism, such as iron, nickel, and steel. Furthermore, the compressed scraps are mixed with impurities such as oil and dust, resulting in high energy consumption and low metal recovery rate when smelting and reusing.

[0003] The utility model with announcement number CN222449430U relates to a waste recycling device for metal door and window processing, including an upper shell structure, a lower shell structure, and a support structure. The lower shell structure is located at the bottom of the upper shell structure. The upper shell structure and the lower shell structure are connected by a snap-fit ​​method. The support structure is located at the bottom of the lower shell structure. The lower shell structure and the support structure are fixedly connected. By setting up a hose and a centrifugal fan, the waste can be sucked in through the hose. By setting up a collection box in the lower shell, the waste can be collected and recycled. By setting up a screening component in the lower shell structure, the waste of different sizes can be screened. By setting up a magnetic suction plate in the large particle collection box, magnetically attracted and non-magnetically attracted metal can be separated.

[0004] The above-mentioned technical solution, by having a switch door on the collection box, allows the collection box to be pulled out by the handle when it is necessary to clean the debris inside, and the debris can be poured out directly through the switch door, which improves the work efficiency of employees. However, the metal debris is of different sizes, and large pieces of metal debris are easy to get stuck inside the hose and cause blockage. The magnetic suction plate is fixed in position, and it is easy for the magnetic suction plate to be filled with metal debris. The metal debris on the magnetic suction plate cannot be automatically collected, requiring frequent manual shutdowns for cleaning. The magnetic suction plate is not electrified, so manual cleaning requires frequent scraping or tapping of the magnetic suction plate. The sharp edges of the metal debris can easily cut the operator's hands. Summary of the Invention

[0005] The purpose of this invention is to provide a metal scrap processing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A metal scrap processing device includes a crushing component at the bottom of the feed inlet, a screening component at the bottom of the crushing component, two vertically arranged first collection slots at the bottom of the screening component near the left end, a separation component for magnetic separation of metal scraps at the inside of the housing corresponding to the first collection slots, and cleaning components symmetrically arranged at the front and back of the first collection slots.

[0008] The crushing assembly includes two symmetrically arranged crushing rollers and a plurality of crushing teeth arranged at equal intervals on the crushing rollers. A rotary motor is provided at one end of the front crushing roller.

[0009] The screening assembly includes a screen plate at the bottom of the crushing roller and springs at the bottom of each of the four corners of the screen plate. A support rod is provided in the middle of the springs, and a vibration motor is provided near the bottom of the rear end of the screen plate.

[0010] The separation assembly includes cylindrical cams symmetrically arranged at the front and rear, and an electromagnetic chuck plate located in the middle of the cylindrical cams;

[0011] The cleaning component includes a first rotating shaft and a first rotating rod located at the inner end of the first rotating shaft. A second rotating rod is located at the inner end of the first rotating rod. A slide rail is located at the bottom of the first rotating shaft. A groove is formed in the middle of the slide rail. A moving block is located at one end of the second rotating rod corresponding to the groove. A scraper is located between the moving blocks at both the front and rear ends.

[0012] Preferably, the rotary motor has a support plate at its bottom, the output shaft of the rotary motor is coaxially connected to the front crushing roller, a plurality of crushing teeth are welded and fixed to the crushing roller at corresponding positions, each crushing roller has a gear at its right end, the two gears at the front and rear ends mesh with each other, the gears are symmetrically arranged with the rotary motor at the front and rear ends, the right end of the rear crushing roller is rotatably connected to the inner wall of the housing at the corresponding position, the front first double synchronous wheel and the front gear are coaxially connected to the rotary motor, the rear first double synchronous wheel has a pin in the middle, the pin is rotatably connected to the inner wall of the housing at the corresponding position, and the outer ring of the front and rear first double synchronous wheels is fitted with a first synchronous belt.

[0013] In this invention, the two crushing rollers at the front and rear ends are integrally formed with the corresponding gears. By turning on the rotary motor, the gears and the first double synchronous pulley at the front end are driven to rotate, which in turn drives the first synchronous belt to rotate, so that the gears at the front and rear ends and the corresponding crushing rollers rotate in opposite directions. The rotary motor is set to provide a stable power source. It cooperates with the staggered crushing teeth on the two crushing rollers to crush the metal scrap entering the feed inlet, reducing the degree of blockage of the metal scrap at the feed inlet.

[0014] Preferably, the spring has a base at its bottom, the vibrating motor has a motor box on its exterior, the motor box is welded and fixed to the screen plate, and the housing has a second storage groove at the front end corresponding to the screen plate.

[0015] In this invention, the screen plate is tilted at 15 degrees, with the front end of the screen plate being lower than the rear end. One end of the base is bonded and fixed to the inner wall of the housing. The upper and lower ends of the spring are bonded and fixed to the screen plate and the base, respectively. The top of the support rod is welded and fixed to the screen plate, and the bottom of the support rod is provided with a support groove corresponding to the base. The support rod and the support groove are slidably connected. The support rod cooperates between the screen plate and the base, which helps the screen plate to move stably up and down in the vertical direction. The spring absorbs the vibration energy of the screen plate through elastic deformation. A vibration motor is set at the bottom of the screen plate to reduce the situation of metal scraps clogging the mesh. At the same time, metal scraps larger than the mesh are sent into the second collection groove.

[0016] Preferably, the right end of the top cylindrical cam is provided with a second double synchronous pulley, and the left end of the top cylindrical cam and both the left and right ends of the bottom cylindrical cam are provided with third synchronous pulleys. The right end of the second double synchronous pulley at the front end and the outer ring of the left end of the first double synchronous pulley on the front crushing roller, and the right end of the second double synchronous pulley at the rear end and the outer ring of the left end of the first double synchronous pulley on the rear crushing roller are fitted with a second synchronous belt. The left end of the second double synchronous pulley at the right end of the cylindrical cam and the corresponding outer ring of the bottom third synchronous pulley, and the outer rings of the two third synchronous pulleys distributed vertically on the left end of the cylindrical cam are fitted with a third synchronous belt. The outer ring surface of the cylindrical cam has a closed curved groove, and the front and rear ends of the electromagnetic chuck and the corresponding positions inside the closed curved groove are provided with rotating blocks.

[0017] In this invention, a rotary motor drives the first double-linked synchronous pulley to rotate, which in turn drives the second double-linked synchronous pulley inside the second synchronous belt to rotate. This causes the top cylindrical cam, coaxially connected to the second double-linked synchronous pulley, to rotate synchronously. The rotation of the second double-linked synchronous pulley drives the third synchronous pulley inside the third synchronous belt to rotate, thus achieving synchronous rotation of the bottom cylindrical cam. When the electromagnetic chuck is energized, the coil inside generates a strong magnetic field. The magnetic lines of force penetrate the outer surface of the electromagnetic chuck and attract ferromagnetic metal debris. The rotating block is rotatably connected to the electromagnetic chuck. This rotatable connection facilitates the adjustment of the rotating block to align with the closed curved groove, enabling the rotating block to drive the electromagnetic chuck to move horizontally back and forth. The closed curved groove is wider at the bottom and narrower at the top, preventing the rotating block from falling out of the groove during movement. The electromagnetic chuck facilitates the loading of various items. Metal scraps such as iron, nickel, and steel with high magnetic permeability and strong magnetism are separated and adsorbed for collection. The length of the electromagnetic chuck is adapted to the inner wall of the first collection tank, the width of the electromagnetic chuck is the same as the width of the screen plate, and the length of the electromagnetic chuck is longer than the screen plate, so as to adsorb the metal scraps falling through the screen plate. The top electromagnetic chuck and the bottom electromagnetic chuck are placed alternately. The staggered placement of the two electromagnetic chucks can increase the coverage of the magnetic field on the inner wall of the shell. When the two cylindrical cams rotate synchronously, the rotating block drives the upper and lower electromagnetic chucks to move horizontally back and forth in the shell. Sliding openings are opened at the inner walls of the front and rear ends of the first collection tank at the same level as the rotating block, so as to facilitate the movement of the electromagnetic chucks into the first collection tank and facilitate continuous magnetic separation and adsorption collection of metal scraps.

[0018] Preferably, a first bevel gear is provided between the outer ring of the left end of the cylindrical cam and the third synchronous pulley, a second bevel gear is provided at the outer end of the first bevel gear, a fourth synchronous pulley is provided at the middle of the outer end of the second bevel gear, and a second rotating shaft is provided between the second bevel gear and the fourth synchronous pulley.

[0019] In this invention, the first bevel gear is coaxially connected to the cylindrical cam. The rotation of the second double synchronous pulley and the third synchronous pulley respectively drives the corresponding first bevel gear to rotate. The second bevel gear and the fourth synchronous pulley are welded and fixed to the corresponding parts of the first rotating shaft. The first rotating shaft is rotatably connected to the corresponding part of the inner wall of the housing. The second bevel gear meshes with the first bevel gear, so that the rotation of the first bevel gear drives the second bevel gear, the fourth synchronous pulley and the first rotating shaft to rotate synchronously. The rotation of the fourth synchronous pulley drives the fifth synchronous pulley in the fourth synchronous belt to rotate synchronously. At this time, the rotary motor is turned on to drive the crushing component and the separation component to run synchronously.

[0020] Preferably, the outer end of the first rotating shaft is provided with a fifth synchronous pulley, and the outer ends of the fifth synchronous pulley and the fourth synchronous pulley are fitted with a fourth synchronous belt. The first rotating shaft is welded and fixed to the first rotating rod. The outer end of the first rotating rod is rotatably connected to the corresponding position of the second rotating rod. The second rotating rod is rotatably connected to the top of the moving block. The moving block is slidably connected to the slide rail. The moving block and the scraper are integrally formed.

[0021] In this invention, the fifth synchronous wheel is welded and fixed to the second rotating shaft. The rotation of the fifth synchronous wheel drives the first rotating rod, which is welded and fixed to the second rotating shaft, to rotate synchronously. This enables the second rotating rod, which is rotatably connected to the first rotating rod, to rotate around the second rotating shaft. The slide rail is bonded and fixed to the inner wall of the first storage groove, causing the moving block, which is rotatably connected to the second rotating rod, to move back and forth along the slide groove on the slide rail. The slide groove limits the forward and backward movement range of the scraper, enabling the scraper to move smoothly. The scraper is perpendicular to the slide rail, and the bottom position of the scraper is adapted to the top of the electromagnetic suction plate. When the electromagnetic suction plate moves into the first storage groove, the moving block moves, causing the scraper to move back and forth on the top surface of the electromagnetic suction plate.

[0022] Preferably, the inner wall of the housing is provided with a power-off button at a horizontal position corresponding to the front end of the first storage slot and the electromagnetic suction plate, and power-on buttons are provided on the inner walls of both the front and rear ends of the housing. A slot plate is provided at the inner end of the first storage slot, and the top of the slot plate is rotatably connected to the first storage slot at a position corresponding to it. A rectangular block is provided near the top of one end of the slot plate, and the rectangular block and the slot plate are integrally formed.

[0023] In this invention, the power-off button and the power-on button are respectively connected to the corresponding electromagnetic suction plates via wires. The power-off button is located on the inner wall of the first storage slot, so that opening and closing the first storage box does not trigger the power-off button. When the electromagnetic suction plate moves to the slot plate, it pushes the slot plate to rotate into the first storage slot. When the entire electromagnetic suction plate enters the first storage slot, its outer end touches and presses the power-off button. The power-off button is then forcibly separated from the contact point by a spring reset mechanism, cutting off the circuit. At this time, the metal scraps adsorbed on the side and bottom of the electromagnetic suction plate detach from the electromagnetic suction plate and fall into the first storage slot. Meanwhile, the scraper pushes the metal scraps back and forth into the first collection slot on the top surface of the electromagnetic suction plate. The range of the slot plate rotating in the opposite direction to the first collection slot causes the rectangular block to touch and press the power button. When the electromagnetic suction plate moves from the inside of the first collection slot to the middle of the housing, the electromagnetic suction plate pushes the slot plate to rotate towards the middle of the housing, causing the rectangular block to touch and press the power button, forming a current path. At this time, the electromagnetic suction plate has the effect of adsorbing metal scraps. The separation component and cleaning component are set inside the housing to facilitate the automatic scraping and collection of ferromagnetic metal scraps when the rotating motor is turned on.

[0024] Preferably, the first and second storage slots are respectively provided with a first storage box for collecting ferromagnetic metal waste and a second storage box for collecting metal waste that has not passed through the screen plate after being crushed. A third storage slot is opened at the bottom of the shell, and a third storage box for collecting non-ferromagnetic metal waste is provided in the third storage slot.

[0025] In this utility model, the first, second, and third storage boxes are each provided with a handle on their surface. The handle is glued and fixed to the surface of the corresponding storage box. A third storage slot is opened at the corresponding position of the shell and the third storage box. The first, second, and third storage boxes are respectively snapped and fixed to the corresponding first and second storage slots. The user can take out the first storage box by using the handle and pour out the ferromagnetic metal waste in the box. The metal waste larger than the screen size in the second storage box is fed back into the feed port for crushing. The user can take out the third storage box and pour out the non-ferromagnetic metal waste in the box.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] 1. This utility model crushes metal scraps by setting a crushing component at the feed inlet, thereby reducing the volume of the metal scraps. In conjunction with the screen plate with a vibrating motor, it reduces the situation where metal scraps larger than the mesh size get stuck on the screen plate. The metal scraps passing through the screen plate are smaller in size, increasing the density of metal scraps accumulated inside the first and second storage boxes. By setting two sets of cylindrical cams inside the shell and placing electromagnetic suction plates at different vertical positions in the middle of the cylindrical cams, the magnetic suction plates can be increased by turning on the rotary motor to drive the electromagnetic suction plates to move back and forth horizontally.

[0028] 2. This utility model uses a scraper that moves back and forth inside the first storage slot to push the magnetic metal debris from the mobile phone on top of the electromagnetic suction plate after the power-off button is touched. This eliminates the need for manual stopping of the machine and manually tapping the electromagnetic suction plate to collect the magnetic metal debris. When the electromagnetic suction plate moves out of the first storage slot, it causes the rectangular block on the slot plate to touch the power-on button, reducing the manual power-on and power-off process and improving the convenience of using the device.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Please see Figures 1-9This embodiment provides a technical solution:

[0046] A metal scrap processing device includes a housing 1 and a feed inlet 10 at the top of the housing 1. A crushing component 2 is provided at the bottom of the feed inlet 10. The crushing component 2 includes two symmetrically arranged crushing rollers 21 and a plurality of crushing teeth 210 arranged at equal intervals on the crushing rollers 21. A rotary motor 20 is provided at one end of the front crushing roller 21. A support plate is provided at the bottom of the rotary motor 20. The output shaft of the rotary motor 20 is coaxially connected to the front crushing roller 21. The plurality of crushing teeth 210 are welded and fixed to the crushing rollers 21 at corresponding positions. A gear 23 is provided at the right end of each crushing roller 21. The two gears 23 at the front and rear ends mesh with each other. A first double synchronous pulley 22 is symmetrically arranged between the gear 23 and the rotary motor 20. The right end of the rear crushing roller 21 is rotatably connected to the inner wall of the housing 1 at the corresponding position. The front first double synchronous pulley 22, the front gear 23 and the rotary motor 20 are coaxially connected. A pin is provided in the middle of the rear first double synchronous pulley 22. The pin is rotatably connected to the inner wall of the housing 1 at the corresponding position. A first synchronous belt 220 is sleeved on the outer ring of the front and rear first double synchronous pulleys 22.

[0047] In this invention, the two crushing rollers 21 at the front and rear ends are integrally formed with the corresponding gears 23. By turning on the rotary motor 20, the gears 23 and the first double synchronous pulley 22 are driven to rotate, and at the same time, the two first synchronous belts 220 are driven to rotate, so that the gears 23 at the front and rear ends and the corresponding crushing rollers 21 rotate towards each other. The rotary motor 20 is set to provide a stable power source. It cooperates with the staggered crushing teeth 210 on the two crushing rollers 21 to crush the metal scrap entering the feed inlet 10, thereby reducing the degree of blockage of the metal scrap in the feed inlet 10.

[0048] The inner wall of the housing 1 is provided with a power button 112 at the horizontal position corresponding to the front end of the first storage slot 11 and the electromagnetic suction plate 41. Power buttons 14 are provided on the inner walls of both the front and rear ends of the housing 1. A slot plate 110 is provided at the inner end of the first storage slot 11. The top of the slot plate 110 is rotatably connected to the first storage slot 11 at the corresponding position. A rectangular block 111 is provided near the top of one end of the slot plate 110. The rectangular block 111 and the slot plate 110 are integrally formed.

[0049] In this invention, the power off button 112 and the power on button 14 are respectively connected to the corresponding electromagnetic suction plate 41 via wires. The power off button 112 is located on the inner wall of the first storage slot 11, so that opening and closing the first storage box 113 does not trigger the power off button 112. When the electromagnetic suction plate 41 moves to the slot plate 110, the electromagnetic suction plate 41 pushes the slot plate 110 to rotate into the first storage slot 11. When the entire electromagnetic suction plate 41 enters the first storage slot 11, the outer end of the electromagnetic suction plate 41 touches and squeezes the power off button 112. The power off button 112 is forced to separate the contacts through the spring 310 reset mechanism, cutting off the circuit. At this time, the metal waste adsorbed on the side and bottom of the electromagnetic suction plate 41 detaches from the electromagnetic suction plate 41 and falls into the first storage slot 11. In the first collection slot 11, the scraper 56 simultaneously pushes the metal scraps back and forth into the first collection slot 11 on the top surface of the electromagnetic suction plate 41. The range of the rotation of the slot plate 110 in the opposite direction to the first collection slot 11 causes the rectangular block 111 to touch and press the power button 14. When the electromagnetic suction plate 41 moves from the inside of the first collection slot 11 to the middle of the inside of the housing 1, the electromagnetic suction plate 41 pushes the slot plate 110 to rotate towards the middle of the housing 1, causing the rectangular block 111 to touch and press the power button 14, forming a current path. At this time, the electromagnetic suction plate 41 has the effect of adsorbing metal scraps. The separation component 4 and the cleaning component 5 are set inside the housing 1 to facilitate the automatic scraping and collection of ferromagnetic metal scraps when the rotary motor 20 is turned on.

[0050] Secondly, the first storage slot 11 and the second storage slot 12 are respectively provided with a first storage box 113 for collecting ferromagnetic metal waste and a second storage box 120 for collecting metal waste that has not passed through the screen plate 31 after being crushed. A third storage slot 13 is opened at the bottom of the shell 1, and a third storage box 130 for collecting non-ferromagnetic metal waste is provided in the third storage slot 13.

[0051] In this utility model, the first storage box 113, the second storage box 120, and the third storage box 130 are each provided with a handle. The handle is glued and fixed to the surface of the corresponding storage box. The shell 1 and the third storage box 13 are respectively provided with a third storage slot 13. The first storage box 113, the second storage box 120, and the third storage box 130 are respectively snapped and fixed to the corresponding first storage slot 11 and second storage slot 12. The user takes out the first storage box 113 by the handle and pours out the ferromagnetic metal waste in the box. The metal waste in the second storage box 120 that is larger than the screen size is fed back into the feed port 10 for crushing. The third storage box 130 is taken out and the non-ferromagnetic metal waste in the box is poured out.

[0052] Specifically, the bottom of the crushing component 2 is provided with a screening component 3. The bottom of the screening component 3 is provided with two vertically arranged first storage slots 11 near the left end. The screening component 3 includes a screen plate 31 at the bottom of the crushing roller 21 and springs 310 at the bottom of each of the four corners of the screen plate 31. A support rod is provided in the middle of the springs 310. A vibration motor 30 is provided near the bottom of the rear end of the screen plate 31. A base 32 is provided at the bottom of the springs 310. A motor box is provided outside the vibration motor 30. The motor box is welded and fixed to the screen plate 31. The housing 1 is provided with a second storage slot 12 at the corresponding front end of the screen plate 31.

[0053] In this invention, the screen plate 31 is tilted at 15 degrees, with the front end of the screen plate 31 being lower than the rear end. One end of the base 32 is bonded and fixed to the inner wall of the housing 1. The upper and lower ends of the spring 310 are bonded and fixed to the screen plate 31 and the base 32, respectively. The top of the support rod is welded and fixed to the screen plate 31. The bottom of the support rod is provided with a support groove corresponding to the base 32. The support rod and the support groove are slidably connected. The support rod cooperates between the screen plate 31 and the base 32, which helps the screen plate 31 to move stably up and down in the vertical direction. The spring 310 absorbs the vibration energy of the screen plate 31 through elastic deformation. A vibration motor 30 is set at the bottom of the screen plate 31 to reduce the situation where metal scraps block the mesh. At the same time, metal scraps larger than the mesh size are sent into the second collection groove 12.

[0054] In addition, the first storage slot 11 is symmetrically equipped with cleaning components 5 at the front and back. The cleaning components 5 include a first rotating shaft 50 and a first rotating rod 53 at the inner end of the first rotating shaft 50. A second rotating rod 530 is provided at the inner end of the first rotating rod 53. A slide rail 55 is provided at the bottom of the first rotating shaft 50. A slide groove 550 is opened in the middle of the slide rail 55. A moving block 54 is provided at one end of the second rotating rod 53 corresponding to the slide groove 550. A scraper 56 is provided in the middle of the moving blocks 54 at both the front and rear ends. A fifth synchronous wheel 51 is provided at the outer end of the first rotating shaft 50. A fourth synchronous belt 510 is sleeved on the outer end of the fifth synchronous wheel 51 and the fourth synchronous wheel 46. The first rotating shaft 50 is welded and fixed to the first rotating rod 53. The outer end of the first rotating rod 53 is rotatably connected to the corresponding position of the second rotating rod 530. The second rotating rod 53 is rotatably connected to the top of the moving block 54. The moving block 54 is slidably connected to the slide rail 55. The moving block 54 and the scraper 56 are integrally formed structures.

[0055] In this utility model, the fifth synchronous wheel 51 is welded and fixed to the second rotating shaft 52. The rotation of the fifth synchronous wheel 51 drives the first rotating rod 53, which is welded and fixed to the second rotating shaft 52, to rotate synchronously. This enables the second rotating rod 530, which is rotatably connected to the first rotating rod 53, to rotate around the second rotating shaft 52. The slide rail 55 is bonded and fixed to the inner wall of the first storage groove 11. This drives the moving block 54, which is rotatably connected to the second rotating rod 530, to move back and forth continuously along the slide groove 550 on the slide rail 55. The slide groove 550 limits the forward and backward movement range of the scraper 56, enabling the scraper 56 to move smoothly. The scraper 56 is perpendicular to the slide rail 55, and the bottom position of the scraper 56 is adapted to the top of the electromagnetic suction plate 41. When the electromagnetic suction plate 41 moves into the first storage groove 11, the moving block 54 moves and drives the scraper 56 to move back and forth on the top surface of the electromagnetic suction plate 41.

[0056] The housing 1 contains a separation component 4 for magnetically separating metal scraps, located inside the first receiving groove 11. The separation component 4 includes symmetrically arranged cylindrical cams 40 and an electromagnetic suction plate 41 between the cylindrical cams 40. A second double-linked synchronous wheel 42 is located at the right end of the top cylindrical cam 40. Third synchronous wheels 43 are located at the left end of the top cylindrical cam 40 and at both ends of the bottom cylindrical cam 40. The right end of the second double-linked synchronous wheel 42 at the front end is connected to the outer ring of the left end of the first double-linked synchronous wheel 22 on the front crushing roller 21. A second synchronous belt 420 is fitted around the right end of the second double synchronous pulley 42 at the top rear end and the left end of the first double synchronous pulley 22 on the rear crushing roller 21. A third synchronous belt 430 is fitted around the outer ring of the second double synchronous pulley 42 at the right end of the cylindrical cam 40 and the corresponding third synchronous pulley 43 at the bottom. Two third synchronous pulleys 43 distributed vertically on the left end of the cylindrical cam 40 are fitted around their outer rings. A closed curved groove 400 is opened on the surface of the outer ring of the cylindrical cam 40. Rotating blocks 410 are provided at both ends of the electromagnetic chuck and the corresponding positions inside the closed curved groove 400.

[0057] In this invention, the rotary motor 20 drives the first double synchronous pulley 22 to rotate, which in turn drives the second double synchronous pulley 42 inside the second synchronous belt 420 to rotate. This causes the top cylindrical cam 40, coaxially connected to the second double synchronous pulley 42, to rotate synchronously. The rotation of the second double synchronous pulley 42 drives the third synchronous pulley 43 inside the third synchronous belt 430 to rotate, thus achieving synchronous rotation of the bottom cylindrical cam 40, coaxially connected to the third synchronous pulley 43. After the electromagnetic chuck 41 is energized, the coil inside generates a strong magnetic field. The magnetic lines of force penetrate the outer surface of the electromagnetic chuck 41 and attract ferromagnetic metal waste. The rotating block 410 is rotatably connected to the electromagnetic chuck 41. This rotatable connection facilitates the adjustment of the rotating block 410 to the same direction as the closed curved groove 400, enabling the rotating block 410 to drive the electromagnetic chuck 41 to move horizontally back and forth. The closed curved groove 400 is wider at the bottom and narrower at the top, preventing the rotating block 410 from falling out of the closed curved groove 400 during movement. The electromagnetic chuck 41 is designed to facilitate the movement of metals with high permeability and... Strongly magnetic metal scraps such as iron, nickel, and steel are separated and collected by adsorption. The length of the electromagnetic suction plate 41 is adapted to the inner wall of the first collection groove 11, the width of the electromagnetic suction plate 41 is the same as the width of the screen plate 31, and the length of the electromagnetic suction plate 41 is longer than the screen plate 31, so as to adsorb the metal scraps falling through the screen plate 31. The top electromagnetic suction plate 41 and the bottom electromagnetic suction plate 41 are placed alternately. The alternate placement of the two electromagnetic suction plates 41 can increase the coverage of the magnetic field on the inner wall of the shell 1. When the two cylindrical cams 40 rotate synchronously, the rotating block 410 drives the upper and lower electromagnetic suction plates 41 to move horizontally back and forth in the shell 1. When the two cylindrical cams 40 rotate synchronously, the rotating block 410 drives the electromagnetic suction plates 41 to move horizontally back and forth in the shell 1. Sliding openings are opened at the inner walls of the front and rear ends of the first collection groove 11 and at the same horizontal level as the rotating block 410, so as to facilitate the movement of the electromagnetic suction plates 41 into the first collection groove 11, which facilitates the continuous magnetic separation and adsorption collection of metal scraps.

[0058] It is worth adding that a first bevel gear 44 is provided between the outer ring of the left end of the cylindrical cam 40 and the third synchronous pulley 43, a second bevel gear 45 is provided at the outer end of the first bevel gear 44, a fourth synchronous pulley 46 is provided at the middle of the outer end of the second bevel gear 45, and a second rotating shaft 52 is provided between the second bevel gear 45 and the fourth synchronous pulley 46.

[0059] In this utility model, the first bevel gear 44 is coaxially connected to the cylindrical cam 40. The rotation of the second double synchronous wheel 42 and the third synchronous wheel 43 respectively drives the corresponding first bevel gear 44 to rotate. The second bevel gear 45 and the fourth synchronous wheel 46 are welded and fixed to the corresponding positions of the first rotating shaft 50. The first rotating shaft 50 is rotatably connected to the corresponding position of the inner wall of the housing 1. The second bevel gear 45 meshes with the first bevel gear 44, so that the rotation of the first bevel gear 44 drives the second bevel gear 45, the fourth synchronous wheel 46 and the first rotating shaft 50 to rotate synchronously. The rotation of the fourth synchronous wheel 46 drives the fifth synchronous wheel 51 in the fourth synchronous belt 510 to rotate synchronously. At this time, the rotary motor 20 is turned on to drive the crushing component 2 and the separation component 4 to run synchronously.

[0060] In this embodiment of the metal scrap processing device, when in use, two crushing rollers 21 with several crushing teeth 210 and gears 23 are first placed inside the feed inlet 10. The rear crushing roller 21 is rotatably connected to the housing 1, and the front crushing roller 21 is coaxially connected to the rotary motor 20 on the support base. A pin shaft rotatably connected to the inner wall of the housing 1 is placed at the rear end of the rear crushing roller 21. A first double synchronous wheel 22 is placed at the left end of the pin shaft and the right end of the front gear 23. A first synchronous belt 220 is sleeved on the outer end of the two first double synchronous wheels 22. The screen plate 31 with a vibrating motor 30 is placed above the base 32. The support rod at the bottom of the screen plate 31 is moved into the support groove. The upper and lower ends of the spring 310 are respectively glued and fixed to the bottom of the screen plate 31 and the corresponding position of the base 32. A second storage groove 12 with a second storage box 120 is opened inside the housing 1 at the position corresponding to the front end of the screen plate 31. Two first storage slots 11 are symmetrically arranged vertically at the left and right ends of the interior. Two cylindrical cams 40 with closed curved grooves 400 are vertically distributed at the front and rear ends of the middle of the housing 1. First bevel gears 44 are symmetrically placed at both ends of the cylindrical cams 40. A second double synchronous pulley 42 with a second synchronous belt 420 is placed at the right end of the top cylindrical cam 40. The other end of the second synchronous belt 420 near the rear end of the housing 1 is fitted on the outer ring of the left end of the first double synchronous pulley 22 at the rear end. The other end of the second synchronous belt 420 near the front end of the housing 1 is fitted on the outer ring of the left end of the first double synchronous pulley 22 at the front end. Third synchronous pulleys 43 are placed at the left end of the top cylindrical cam 40 and the left and right ends of the bottom cylindrical cam 40. The third synchronous pulleys 43 arranged vertically on the left end of the cylindrical cam 40, the left end of the second double synchronous pulley 42 on the right end of the cylindrical cam 40, and the outer ring of the third synchronous pulley 43 at the bottom are all fitted with third synchronous belts 430.

[0061] The rotating blocks 410 at both ends of the electromagnetic chuck 41 are moved into the closed curved groove 400 of the cylindrical cam 40. The groove plate 110 with rectangular blocks 111 is rotatably connected to the inner wall of the first storage groove 11 at the corresponding position. The power off button 112 is placed on the inner wall of the first storage groove 11 near the outer end at the horizontal position of the electromagnetic chuck 41. The power on button 14 is placed on the inner wall at both ends of the housing 1. A first rotating shaft 50 with a second bevel gear 45 is placed on the outer end of the first bevel gear 44. The first rotating shaft 50 is rotatably connected to the housing 1. A section with a rectangular block 111 is placed on the outer ring of the first rotating shaft 50 between the second bevel gear 45 and the inner wall of the housing 1. The fourth synchronous pulley 46 with the fourth synchronous belt 510 is fitted with the outer ring of the fifth synchronous pulley 51 on the outer ring of the second rotating shaft 52. The second rotating shaft 52 passes through the inner wall of the first storage groove 11 and is welded and fixed to the first rotating rod 53 with the second rotating rod 530. The other end of the second rotating rod 530 is rotatably connected to the top of the moving block 54 with the scraper 56. The top of the moving block 54, which is slidably connected to the slide groove 550, is rotatably connected to the second rotating rod 530. The first storage box 113, the second storage box 120 and the third storage box 130 with handles are moved into the corresponding storage grooves respectively.

[0062] After installation, the control switches of the rotary motor 20 and the vibrating motor 30 are activated. The metal scrap to be processed is placed into the feed inlet 10. After passing through two opposing rotating crushing rollers 21 and the crushing teeth 210 on the crushing rollers 21, large pieces of metal scrap are crushed into smaller particles. The crushed metal scrap falls onto the surface of the continuously vibrating screen plate 31. The mesh on the vibrating screen plate 31 retains the larger metal scrap on the top surface of the screen plate 31. The inclined screen plate 31, in conjunction with the vibrating motor 30, transfers the metal scrap retained on the top of the screen plate 31 to the second collection box 1. Inside the screen 20, metal scrap smaller than the mesh size falls through the mesh into the middle of the housing 1, reducing the clogging of the screen plate 31. The rotary motor 20 starts and drives the electromagnetic suction plate 41 to move back and forth along the cylindrical cam 40 and attract ferromagnetic metal scrap. When the electromagnetic suction plate 41 enters the first collection slot 11 and the power off button 112 is pressed, the electromagnetic suction plate 41 is de-energized. The metal scrap attracted by the sides and bottom of the electromagnetic suction plate 41 detaches from the electromagnetic suction plate 41 and falls into the first collection box 113. The scraper 56 inside the first collection slot 11 simultaneously moves the electromagnetic suction plate... The metal scraps at the top of the 41 are pushed into the first storage box 113. The cylindrical cam 40 drives the electromagnetic suction plate 41 to move from inside the first storage slot 11 towards the middle of the housing 1. The electromagnetic suction plate 41 pushes the slot plate 110 to rotate outward from the first storage slot 11, causing the rectangular block 111 on the slot plate 110 to press the power button 14. At this time, the electromagnetic suction plate 41 is powered on and attracts the ferromagnetic metal scraps and continues to move until it reaches the first storage slot 11 at the other end of the housing 1. Then, the power is turned off again and it works with the reciprocating scraper 56 to automatically clean the ferromagnetic metal scraps on the electromagnetic suction plate 41. The step of manually cleaning the electromagnetic suction plate 41 in the shell 1 is eliminated, avoiding the possibility of sharp metal scraps scratching the operator's skin. It also increases the range of the electromagnetic suction plate 41 for adsorbing ferromagnetic metal scraps. The remaining metal scraps adsorbed by the two electromagnetic suction plates 41 arranged vertically fall into the third storage box 130. The user pours the metal scraps in the second storage box 120 into the feed port 10 for re-crushing, screening and magnetic separation until all the metal scraps are processed. Then, the first storage box 113 and the third storage box 130 are pulled out, and the separated metal scraps are taken out and dumped.
