Description

Technical Field

[0001] This application relates to the technical field of crushing equipment, and in particular to a waste automobile resource recycling and processing equipment. Background Technology

[0002] With societal progress and development, the number of cars on the road is increasing. Since cars have a limited lifespan, they are often dismantled in factories for recycling. The car body is primarily made of metal; after other parts are removed, a crusher is typically used to crush the car body to facilitate metal recovery. Replacing virgin materials with recycled materials (such as metals and plastics) in production significantly reduces energy consumption during manufacturing, achieving direct energy savings. Furthermore, most existing crushers use energy-efficient motors for even better energy conservation.

[0003] For example, Chinese patent document CN112705312B discloses a crusher for dismantling scrapped automobiles, including a shell and a crushing device. The shell has an inlet and an outlet. The crushing device includes a drive motor and two parallel crushing rollers. The drive motor is located outside the shell, and the crushing rollers are located inside the shell. The crushing device is located between the inlet and the outlet. It also includes a feeding device and a screening device. The feeding device includes a feeding cylinder and a feeding plate. The feeding cylinder is rotatably connected to the outer wall of the shell. The feeding plate includes a connecting plate and a support plate. The connecting plate is rotatably connected to the piston rod of the feeding cylinder. One side of the connecting plate near the inlet is rotatably connected to the shell, and the other side is connected to the support plate. The screening device is located below the outlet and is used to screen metal. In use, the metal to be crushed falls from the feeding outlet into the shell and above the two crushing rollers. The crushed metal falls onto the screening screen. The vibrator is turned on, and the screen vibrates. Small pieces of metal fall through the mesh of the screen onto the conveyor belt below for further processing. Large pieces of metal move to the lower side of the screen under the vibration of the vibrator and fall into the recycling bin below.

[0004] In the aforementioned related technologies, the broken metal falls onto the screening screen. The vibrator is turned on, and the vibrator drives the screening screen to vibrate. Small pieces of metal fall from the mesh of the screen onto the conveyor belt below, while larger pieces of metal remain above the screening screen. Then, under the vibration of the vibrator, the larger pieces of metal move to the lower side of the screening screen and fall into the collection box below. During the screening process, some broken metal may get stuck in the mesh of the screening screen. If the metal stuck in the mesh cannot fall off under vibration, it will affect the screening efficiency of the screening screen. Summary of the Invention

[0005] This application provides a waste vehicle resource recovery and recycling device, which aims to solve the problem of metal getting stuck in the mesh of the screening screen in related technologies.

[0006] The technical solution adopted in this application for a waste vehicle resource recovery and recycling equipment is as follows: A waste automobile resource recycling and processing device includes a frame and a crushing shell mounted on the frame. The crushing shell contains a crushing assembly for crushing automotive metal parts. An energy-saving electric motor is mounted on the frame to drive the crushing assembly. The crushing shell has a feed inlet and a screening assembly at the feed inlet. The screening assembly screens the crushed metal. The screening assembly includes a mounting frame within the crushing shell, a first screening screen fixed to the mounting frame, and a second screening screen slidably connected to the first screening screen. The mesh size of the first screening screen is the same as that of the second screening screen. The first screening screen has a hollow structure. The second screening screen is located inside the first screening screen and slides within it. A control assembly is mounted on the mounting frame to drive the second screening screen to slide on the first screening screen.

[0007] By adopting the above technical solution, when crushing metal, a robotic arm puts metal parts from scrapped cars into the crushing housing through the feed inlet, and then they fall onto the crushing assembly. The crushing assembly crushes the metal parts, and the crushed metal falls onto the first screening screen. The crushed metal is screened through the overlapping screening holes of the first and second screening screens. During the screening process, some metal gets stuck in the overlapping mesh of the first and second screening screens. If it is not cleaned in time, it will affect the screening effect. At this time, the control component drives the second screening screen to move. During the movement of the second screening screen, the overlapping area of ​​the screening holes on the first and second screening screens becomes smaller, which squeezes the metal stuck in the screening holes. During the squeezing process, the metal becomes smaller. Then the control component drives the second screening screen to reverse and reset. Finally, the smaller metal falls out of the overlapping screening holes of the first and second screening screens, thus achieving the purpose of automatically cleaning the screening screen holes. Since the crushing roller is driven by an energy-saving motor, high efficiency and energy saving can be achieved.

[0008] Optionally, the control component includes a control rod fixed to the second screening mesh and a control cylinder fixed to the control rod. The cylinder body of the control cylinder is fixed to the mounting frame. The control rod is located at the bottom of the second screening mesh, and the control cylinder is located at the bottom of the mounting frame. A moving groove is provided at the bottom of the first screening mesh, and the control rod is slidably connected in the moving groove.

[0009] By adopting the above technical solution, when it is necessary to adjust the overlapping area of ​​the screening mesh holes on the first screening mesh and the second screening mesh, the control cylinder drives the control rod to move, and the control rod drives the second screening mesh to slide on the first screening mesh, thereby adjusting the overlapping area of ​​the screening mesh holes on the first screening mesh and the second screening mesh.

[0010] Optionally, the crushing shell is provided with a pushing chamber. One end of the pushing chamber is connected to the inside of the crushing shell above the first screening screen, and the other end is also connected to the inside of the crushing shell. One end of the pushing chamber is located above the crushing roller, and the other end is located below the crushing roller. A pushing component is provided in the pushing chamber. The pushing component is used to push large pieces of metal above the screening component into the crushing component, and the large pieces of metal are crushed again by the crushing component.

[0011] By adopting the above technical solution, the large pieces of metal after crushing cannot fall from the screening mesh of the first and second screening meshes. At this time, the large pieces of metal on the first screening mesh are pushed by the pushing component to move from the opening at the lower end of the pushing chamber to the opening at the upper end, and finally enter the crushing shell from the upper opening. The large pieces of metal are crushed again by the crushing component, so that the size of the crushed metal meets the standard.

[0012] Optionally, the pushing assembly includes a mounting ring rotatably connected inside the crushing shell, a mounting rod fixed on the mounting ring, and a pushing plate fixed on the mounting rod. The pushing plate is arranged along the length direction of the rotation axis, and the pushing plate is provided with a first pushing groove. Multiple first pushing grooves are provided, and the multiple first pushing grooves are evenly spaced along the length direction of the pushing plate.

[0013] By adopting the above technical solution, the mounting ring rotates, which drives the mounting rod to move. The mounting rod drives the pusher plate to move, and the pusher plate pushes the metal on the first screening screen to move from the opening at the lower end of the pusher chamber to the opening at the upper end. Finally, it enters the crushing shell through the upper opening, and the large pieces of metal are crushed again by the crushing components, which makes the crushing process more convenient.

[0014] Optionally, the pusher plate is provided with a movable plate, and the movable plate is provided with a second pusher groove. Multiple second pusher grooves are provided and spaced apart along the length direction of the movable plate. The movable plate slides on the pusher plate. The crushing shell is provided with a pusher assembly, which is used to drive the movable plate to move on the sliding plate and adjust the overlapping area of ​​the first pusher groove and the second pusher groove.

[0015] Optionally, the pusher plate is provided with a support spring, one end of which is fixed to the movable plate and the other end is fixed to the pusher plate.

[0016] Optionally, the mounting frame is slidably connected inside the crushing shell, and a reset assembly is provided inside the crushing shell. The reset assembly is used to drive the mounting frame and the first and second screening screens set inside the mounting frame to reset. The reset assembly includes a reset rod fixed on the crushing shell and a reset spring sleeved on the reset rod. One end of the reset spring is fixed on the mounting frame, and the other end is fixed on the inner wall of the crushing shell.

[0017] Optionally, the pushing assembly includes a pushing block fixed to the inner wall of the crushing housing and a pushing rod fixed to the moving plate. The pushing block is provided with a pushing inclined surface. The supporting spring pushes one end of the pushing rod to abut against the pushing inclined surface. The pushing inclined surface is used to connect the inner wall of the crushing housing and the surface of the pushing block. The surface of the pushing block protrudes from the inner wall of the crushing housing.

[0018] Optionally, an installation shaft is rotatably connected inside the crushing shell, and a baffle is fixedly installed on the installation shaft. The baffle is used to block the opening at the upper end of the pushing chamber.

[0019] Optionally, the mounting frame is tilted so that one side of the mounting frame is higher than the other side, and both the first screening screen and the second screening screen on the mounting frame are tilted.

[0020] By adopting the above technical solution, due to the inclined setting of the installation frame, both the first and second screening screens on the installation frame are inclined. Then, the crushed metal falls onto the first screening screen. Because the first screening screen is inclined, large pieces of metal will move to one end of the bottom of the first screening screen. Finally, it is convenient for the pushing component to push the large pieces of metal into the crushing roller, so that the crushing roller can crush the large pieces of metal again.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The control component drives the second screening screen to move. During the movement of the second screening screen, the overlapping area of ​​the screening holes on the first and second screening screens decreases, which squeezes the metal stuck in the screening holes. During the squeezing process, the metal becomes smaller. Then, the control component drives the second screening screen to reverse and reset. Finally, the metal that has become smaller will fall out of the screening holes where the first and second screening screens overlap, thus achieving the purpose of automatically cleaning the screening screen holes. Since the crushing roller is driven by an energy-saving motor, high efficiency and energy saving can be achieved.

[0022] 2. Large pieces of metal after crushing cannot fall through the screening holes of the first and second screening screens. At this time, the large pieces of metal on the first screening screen are pushed by the pushing component to move from the lower opening of the pushing chamber to the upper opening, and finally enter the crushing shell through the upper opening. The crushing component crushes the large pieces of metal again, thereby making the size compliance rate of the crushed metal higher. Attached Figure Description

[0031] The following combination Figures 1-7 This application will be described in further detail.

[0032] This application discloses a waste vehicle resource recovery and recycling device. (Refer to...) Figures 1 to 7A waste automobile resource recycling and processing device includes a frame 1 and a crushing shell 11 mounted on the frame 1. A crushing component 2 is installed inside the crushing shell 11 for crushing automobile metal parts. A drive component is installed on the frame to drive the crushing component 2. An inlet 12 and an outlet 13 are provided on the crushing shell 11. A screening component 3 is installed at the outlet 13 for screening the crushed metal. At the same time, a pushing component 4 is installed inside the crushing shell 11 to push large pieces of metal above the screening component 3 into the crushing component 2. The crushing component 2 further crushes the large pieces of metal, while smaller pieces of metal fall onto a conveying component through the screening component 3 and are then conveyed by the conveying component below.

[0033] The crushing assembly 2 includes two rotating shafts 21 rotatably connected to the crushing housing 11 and crushing rollers 22 fixed on the rotating shafts 21. The two crushing rollers 22 crush the parts of the scrapped car, which facilitates the subsequent recycling of the crushed metal. The drive assembly is used to drive the two rotating shafts 21 to rotate in opposite directions. Then, the metal to be crushed is put into the crushing housing 11 through the feed port 12, and the metal is crushed and recycled by the two oppositely rotating crushing rollers 22.

[0034] The drive assembly includes a reducer fixed on the frame 1 and a motor fixed on the frame 1. The output shaft of the motor is fixedly connected to the input shaft of the reducer on the frame 1, and the output shaft of the reducer is fixedly connected to the rotating shaft 21. In this embodiment, since there are two rotating shafts 21, there are also two drive assemblies. Each drive assembly corresponds to one rotating shaft 21. During the operation of the two motors, the two rotating shafts 21 are driven to rotate in opposite directions. During the rotation of the rotating shafts 21, the crushing rollers 22 will be driven to rotate. The metal inside the crushing housing 11 is crushed by the two rotating crushing rollers 22.

[0035] In this embodiment, to improve energy efficiency, the motor is configured as an energy-saving motor. The energy-saving motor uses high conductivity materials (such as cast copper rotor) to reduce resistance loss, uses low iron loss silicon steel sheets to reduce hysteresis and eddy current effects, improves the cooling system to avoid overheating, and uses permanent magnet synchronous technology to replace traditional excitation with neodymium iron boron magnets to eliminate copper loss and improve the power factor. Combined with frequency conversion control, the speed is dynamically adjusted according to the load so that the motor always operates in the high-efficiency range, thereby achieving energy saving.

[0036] The screening assembly 3 includes a mounting frame 31 disposed within the crushing shell 11, a first screening screen 32 fixed on the mounting frame 31, and a second screening screen 33 slidably connected to the first screening screen 32. The mesh size of the first screening screen 32 is the same as that of the second screening screen 33. The first screening screen 32 is a hollow structure, and the second screening screen 33 is disposed inside the first screening screen 32 and slides inside the first screening screen 32. A control assembly 5 is disposed on the mounting frame 31. The control assembly 5 is used to drive the second screening screen 33 to slide on the first screening screen 32. By adjusting the position of the second screening screen 33, the overlapping area of ​​the meshes on the first screening screen 32 and the second screening screen 33 can be adjusted.

[0037] When the mesh openings on the first screening mesh 32 and the second screening mesh 33 completely overlap, the screening component 3 will screen out the largest metal. The position of the second screening mesh 33 can be adjusted as needed via the control component 5. Then, the crushed metal is screened through the first and second screening meshes 32 and 33. If metal gets stuck at the overlapping mesh openings of the first and second screening meshes 32 and 33, the control component 5 can move the second screening mesh 33. During this movement, the stuck metal can be squeezed. After squeezing, the second screening mesh 33 resets, and the squeezed metal falls out of the overlapping mesh openings, thus clearing the stuck metal. Simultaneously, the control component 5 can also move the second screening mesh 33 in the opposite direction. When the second screening mesh 33 moves in the opposite direction, the overlapping area of ​​the mesh openings of the first and second screening meshes 32 and 33 increases, facilitating the falling of stuck metal and thus achieving the purpose of easily clearing the stuck metal from the mesh openings.

[0038] The control component 5 includes a control rod 51 fixed to the second screening screen 33 and a control cylinder 52 fixed to the control rod 51. The cylinder body of the control cylinder 52 is fixed to the mounting frame 31. The control rod 51 is located at the bottom of the second screening screen 33, and the control cylinder 52 is located at the bottom of the mounting frame 31. A moving groove is provided at the bottom of the first screening screen 32, and the control rod 51 is slidably connected in the moving groove. In this embodiment, two control cylinders 52 are provided, which makes it easier to adjust the position of the second screening screen 33. In addition, in order to improve the screening efficiency of the screening component 3, a vibration motor is provided on the mounting frame 31. The vibration motor vibrates the first screening screen 32 and the second screening screen 33. Since the vibration motor is prior art, the specific structure and working principle of the vibration motor will not be described in detail in this embodiment.

[0039] The mounting frame 31 is tilted so that one side of the mounting frame 31 is higher than the other side. Due to the tilted setting of the mounting frame 31, both the first screening screen 32 and the second screening screen 33 on the mounting frame 31 are tilted. This facilitates the movement of large pieces of metal on the surface of the first screening screen 32 towards the lower position. Finally, it is easy for the pushing component 4 to push the large pieces of metal back into the space between the two crushing rollers 22. The two crushing rollers 22 crush the large pieces of metal again. During the entire crushing process, there is no need to collect the large pieces of metal separately, which makes the amount of crushed metal more in line with the requirements, thereby improving the overall crushing efficiency of the metal.

[0040] A pushing chamber 6 is provided inside the crushing shell 11. One end of the pushing chamber 6 is connected to the interior of the crushing shell 11 above the first screening screen 32, and the other end is also connected to the interior of the crushing shell 11. One end of the pushing chamber 6 is positioned above the crushing roller 22, and the other end is positioned below the crushing roller 22. Then, the pushing assembly 4 pushes the metal on the first screening screen 32 from the lower opening to the upper opening of the pushing chamber 6, and finally enters the area above the two crushing rollers 22 through the upper opening of the pushing chamber. The two crushing rollers 22 then crush the large pieces of metal again. By pushing the large pieces of metal on the first screening screen 32 back into the crushing rollers 22 through the pushing assembly 4, the crushing efficiency can be improved, and energy saving can be achieved.

[0041] An installation shaft 61 is rotatably connected inside the crushing housing 11. A baffle 62 is fixedly installed on the installation shaft 61. The baffle 62 is used to block the opening at the upper end of the pushing chamber 6. By setting the baffle 62, metal can be prevented from entering the pushing chamber 6 from the upper opening during the crushing process. When the pushing assembly 4 pushes the material upward, the pushing assembly 4 and the metal on the pushing assembly 4 will push the baffle 62 to rotate outward. At this time, the opening at the upper end of the pushing chamber 6 is opened, which allows the metal on the pushing assembly 4 to enter the crushing roller 22 from the upper opening of the pushing chamber 6, thereby further crushing large pieces of metal. A torsion spring is sleeved on the installation shaft 61. One end of the torsion spring is fixed to the installation shaft 61, and the other end is fixed to the crushing housing 11. The torsion spring resets the baffle 62, and the reset baffle 62 blocks the opening above the pushing channel.

[0042] The feeding assembly 4 includes a mounting ring 41 rotatably connected within the crushing housing 11, a mounting rod 42 fixed to the mounting ring 41, and a feeding plate 43 fixed to the mounting rod 42. The feeding plate 43 is arranged along the length direction of the rotating shaft 21. The feeding plate 43 is provided with a first feeding groove 44. Multiple first feeding grooves 44 are provided and are evenly spaced along the length direction of the feeding plate 43. A moving plate 45 is provided on the feeding plate 43. Multiple second feeding grooves 46 are provided on the moving plate 45 and are spaced along the length direction of the moving plate 45. The moving plate 45 slides on the pushing plate. A pushing assembly 7 is provided on the crushing housing 11. The pushing assembly 7 is used to drive the moving plate 45 to move on the sliding plate and then adjust the overlapping area of ​​the first feeding groove 44 and the second feeding groove 46.

[0043] The mounting frame 31 is slidably connected inside the crushing housing 11, and a reset assembly 8 is provided inside the crushing housing 11. The reset assembly 8 is used to reset the mounting frame 31 and the first screening screen 32 and the second screening screen 33 disposed inside the mounting frame 31. The reset assembly 8 includes a reset rod 81 fixed on the crushing housing 11 and a reset spring 82 sleeved on the reset rod 81. One end of the reset spring 82 is fixed on the mounting frame 31, and the other end is fixed on the inner wall of the crushing housing 11. During the process of the mounting ring 41 driving the mounting rod 42 and the pusher plate 43 to rotate in the opposite direction, the pusher plate 43 will push the mounting frame 31, the first screening screen 32 and the second screening screen 33 to move downward. A rotating assembly is provided on the crushing shell 11. The rotating assembly is used to drive the mounting ring 41 to rotate. The mounting ring 41 drives the mounting rod 42 to rotate. The mounting rod 42 drives the pusher plate 43 and the moving plate 45 on the pusher plate 43 to rotate. During the forward rotation, the pusher plate 43 and the moving plate 45 push large pieces of metal into the feed inlet 12. Under the action of the pushing assembly 7, during the forward rotation of the pusher plate 43 and the moving plate 45, the overlapping area of ​​the first pusher groove 44 and the second pusher groove 46 becomes smaller, pushing the metal that the screening assembly 3 cannot screen into the area above the crushing roller 22. During the reverse rotation, the pusher plate 43 and the moving plate 45 increase the overlapping area of ​​the first pusher groove 44 and the second pusher groove 46, thereby reducing the movement of the metal above the first screening screen 32 pushed by the pusher plate 43 and the moving plate 45. In this embodiment, the rotating component is mounted on the rotating motor, which is fixed on the frame 1, and the output shaft of the rotating motor is fixedly connected to the mounting ring 41. The rotating motor drives the mounting ring 41 to rotate.

[0044] A support spring 63 is provided on the pusher plate 43. One end of the support spring 63 is fixed to the moving plate 45, and the other end is fixed to the pusher plate 43. Under the action of the support spring 63, the second pusher groove 46 on the moving plate 45 is misaligned with the first pusher groove 44 on the pusher plate 43, and the overlapping area of ​​the first pusher groove 44 and the second pusher groove 46 is greater than the overlapping area of ​​the mesh on the first screening screen 32 and the mesh on the second screening screen 33, so that the large pieces of metal on the first screening screen 32 can be pushed into the pusher chamber 6.

[0045] The pushing assembly 7 includes a pushing block 71 fixed to the inner wall of the crushing housing 11 and a pushing rod 73 fixed to the moving plate 45. A pushing inclined surface 72 is provided on the pushing block 71. A support spring 63 pushes one end of the pushing rod 73 to abut against the pushing inclined surface 72. The pushing inclined surface 72 connects the inner wall of the crushing housing 11 with the surface of the pushing block 71. The surface of the pushing block 71 protrudes from the inner wall of the crushing housing 11. During the forward rotation of the pushing plate 43 and the moving plate 45, the support spring 63 causes the pushing rod 73 to first move from the surface of the pushing block 71 to the pushing inclined surface 72, and then move from the pushing inclined surface 72... The metal that the screening assembly 3 cannot screen will move onto the inner wall of the crushing shell 11, and then the overlapping area of ​​the first pushing groove 44 and the second pushing groove 46 will gradually decrease, pushing the metal above the crushing roller 22 into the screen. During the reverse rotation of the pushing plate 43 and the moving plate 45, the pushing rod 73 abuts against the pushing inclined surface 72 from the inner wall of the crushing shell 11, and then moves from the pushing inclined surface 72 to the surface of the pushing block 71. During the movement of the pushing rod 73, the overlapping area of ​​the first pushing groove 44 and the second pushing groove 46 gradually increases. At this time, the pushing plate 43 and the moving plate 45 reduce the movement of the metal above the first screening screen 32.

[0046] Metal from scrapped cars is fed into the crushing housing 11 via a robotic arm. Two crushing rollers 22, rotating in opposite directions, then crush the metal. The crushed metal falls onto the first screening screen 32. Metal that meets the requirements falls through the overlapping screening holes of the first and second screening screens 32 and 33. If metal gets stuck at the overlapping position of the first and second screening screens 32 and 33, the control component 5 can move the second screening screen 33. During this movement, the stuck metal is squeezed. After squeezing, the second screening screen 33 resets, and the squeezed metal falls through the overlapping mesh, thus clearing the stuck metal. Larger pieces of metal remain on the first screening screen 32. The rotating component then drives the pushing component 4 to rotate, pushing the large pieces of metal from the first screening screen 32 into the crushing rollers 22 for further crushing.

[0047] Specifically, during the forward rotation of the pusher plate 43 and the moving plate 45, the support spring 63 causes the push rod 73 to first move from the surface of the push block 71 to the push inclined surface 72, and then from the push inclined surface 72 to the inner wall of the crushing shell 11. Then, the overlapping area of ​​the first push groove 44 and the second push groove 46 gradually decreases, pushing the metal that the screening component 3 cannot screen into the area above the crushing roller 22. During the reverse rotation of the pusher plate 43 and the moving plate 45, the push rod 73 abuts against the push inclined surface 72 from the inner wall of the crushing shell 11, and then moves from the push inclined surface 72 to the surface of the push block 71. During the movement of the push rod 73, the overlapping area of ​​the first push groove 44 and the second push groove 46 gradually increases. At this time, the pusher plate 43 and the moving plate 45 reduce the movement of the metal above the first screening screen 32.

[0048] The implementation principle of the end-of-life vehicle resource recycling equipment in this application embodiment is as follows: The metal of the end-of-life vehicle is put into the crushing housing 11 by a mechanical arm, and then crushed by two crushing rollers 22 rotating in opposite directions. The crushed metal falls onto the first screening screen 32. Metal that meets the requirements falls from the screening holes of the first screening screen 32 and the second screening screen 33 that overlap. When metal gets stuck at the overlapping position of the mesh holes of the first screening screen 32 and the second screening screen 33, the control component 5 can drive the second screening screen 33 to move. During the movement, the stuck metal can be squeezed. After squeezing, the second screening screen 33 is reset. At this time, the squeezed metal falls from the overlapping mesh holes, thereby cleaning the metal stuck in the mesh holes. Larger metals will remain on the first screening screen 32. Then, the rotating component drives the pushing component 4 to rotate. The pushing component 4 pushes the large pieces of metal on the first screening screen 32 into the crushing rollers 22, where they are crushed again. During the forward rotation of the pusher plate 43 and the moving plate 45, the support spring 63 causes the push rod 73 to first move from the surface of the push block 71 to the push inclined surface 72, and then from the push inclined surface 72 to the inner wall of the crushing shell 11. Then the overlapping area of ​​the first push groove 44 and the second push groove 46 gradually decreases, pushing the metal that the screening component 3 cannot screen into the area above the crushing roller 22. During the reverse rotation of the pusher plate 43 and the moving plate 45, the push rod 73 abuts against the push inclined surface 72 from the inner wall of the crushing shell 11, and then moves from the push inclined surface 72 to the surface of the push block 71. During the movement of the push rod 73, the overlapping area of ​​the first push groove 44 and the second push groove 46 gradually increases. At this time, the pusher plate 43 and the moving plate 45 reduce the movement of the metal above the first screening screen 32.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
