Description

Technical Field

[0001] This invention relates to the field of metal product screening technology, and more specifically, to a product screening device for intelligent manufacturing of metal materials and its usage method. Background Technology

[0002] Metallic materials refer to materials with properties such as luster, ductility, electrical conductivity, and thermal conductivity. They are generally divided into ferrous metals and non-ferrous metals. Ferrous metals include iron, chromium, manganese, etc. Among them, steel is a basic structural material. Due to its good hardness, strength, and luster, steel is often used to make industrial parts. Bearing sleeves are an industrial product made of steel. After the bearing sleeves are cast, a screening device is needed to screen the processed bearing sleeves to separate good and defective bearing sleeves.

[0003] An efficient bearing ring screening device with publication number CN111069050A is disclosed. The device collects bearing rings into the feed inlet through a conveyor chain in the feeding assembly, and conveys the bearing rings through a push cylinder and a push plate. The bearing rings are cleaned by the screening assembly and screened by the screening plate, thereby improving the operation efficiency.

[0004] However, when inspecting bearing sleeves, this device cannot inspect the inner wall of the bearing sleeve. During the casting process, some bearing sleeves deform during cooling, resulting in irregular protrusions on the inner wall. Such bearing sleeves cannot meet the product's usage requirements.

[0005] In view of this, this application proposes a product screening device for intelligent manufacturing of metal materials and its usage method. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention proposes a product screening device for intelligent manufacturing of metal materials and its usage method.

A U-shaped rod is fixed to the side of the transmission rod away from the fine screen, and the striking plate is located on the inner wall of the U-shaped rod.

[0014] Furthermore, the rejection assembly includes a side plate, which is fixed to one side of the push block. A first spring is fixed to the inner wall of the side plate, and a push plate is fixed to the bottom of the first spring. A lifting plate is fixed to one side of the push plate. The lifting plate is trapezoidal in shape and is located at the top of a set of insert rods. A pad is fixed to the bottom of the lifting plate.

[0015] Furthermore, the cleaning component includes a support block fixed to the inner wall of the push block, a cleaning block fixed to the side of the support block away from the push block, and a brush fixed to the side of the cleaning block away from the support block, the brush being disposed on one side of a set of clips.

[0016] Furthermore, the cleaning block has an air intake hole on the side near the brush. Multiple sets of air intake holes are arranged in parallel on one side of the cleaning block. A transmission pipe is fixed to the inner wall of the support block. The transmission pipe is located on one side of the air intake hole. The transmission pipe is a telescopic pipe. The bottom of the transmission pipe extends into the inner wall of the cleaning cylinder. An air intake hood is fixed to the side of the transmission pipe that extends into the inner wall of the cleaning cylinder. The bottom of the transmission pipe and the air intake hood are located between the fine screen and the coarse screen.

[0017] The technical effects and advantages of the product screening device and its usage method for intelligent manufacturing of metal materials according to the present invention are as follows:

[0018] (1) By setting a rod and a sleeve on the outer wall of the second conveyor belt, the present invention can insert the rod and the sleeve into the inner wall of the bearing sleeve body when it is necessary to screen the bearing sleeve body. Due to the characteristics of the sleeve being made of sponge material, when the bearing sleeve body with irregular protrusions on the inner wall is encountered, it will be stuck on the sleeve. Therefore, when the bearing sleeve body is removed from the top of the first conveyor belt, the bearing sleeve body with a complete and qualified inner wall will first fall down into the turning cylinder by gravity, while the bearing sleeve body with irregular protrusions on the inner wall will continue to move to one side until the rejection component removes the unqualified bearing sleeve body from the outer wall of the sleeve. This facilitates the screening of qualified bearing sleeve bodies and separates the bearing sleeve bodies with irregular protrusions on the inner wall, solving the problem that the inner wall of the bearing sleeve body is not easy to detect.

[0019] (2) By installing a rotary motor, a circular plate and a partition on the inner wall of the tilting cylinder, the qualified bearing sleeve body can be tilted between the two sets of partitions, thereby changing the position of the qualified bearing sleeve body. When the suction force generated by the fan cleans the metal debris on the outer wall of the qualified bearing sleeve body, the different positions of the qualified bearing sleeve body can be adjusted to facilitate the cleaning of the metal debris on the outer wall of the qualified bearing sleeve body. The protective pad installed on the outer wall of the partition can protect the outer wall of the qualified bearing sleeve body and prevent the qualified bearing sleeve body from being damaged during tilting.

[0020] (3) While the circular plate rotates, it can drive the L-shaped rod to rotate together. The rotation of the L-shaped rod pushes one side of the striking plate upward, so that the bottom of the striking plate hits the bottom of the inner wall of the U-shaped rod. After the L-shaped rod passes the striking plate, the second spring resets the striking plate to hit the top of the inner wall of the U-shaped rod. This process is repeated to continuously hit the U-shaped rod, causing it to vibrate continuously. The vibration generated by the U-shaped rod is transmitted to the fine screen through the transmission rod, thereby improving the efficiency of shaking off metal debris from the fine screen.

[0021] (4) By setting a support block, a cleaning block and a brush on the inner wall of the push block, the outer wall of the cassette that passes through the inner wall of the push block can be cleaned and the metal debris on the outer wall of the cassette can be scraped off. The suction generated by the transmission pipe can make the suction hole on one side of the cleaning block generate suction, which can easily suck the scraped metal debris into the transmission pipe and transmit the metal debris into the cleaning cylinder through the transmission pipe. At the same time as cleaning the outer wall of the cassette, it is convenient to collect and process the cleaned metal debris.

[0022] (5) By setting up a first collection box, a second collection box and a third collection box, it is convenient to collect and store qualified bearing sleeve bodies, unqualified bearing sleeve bodies and metal scraps separately. By setting a glass plate on the top of one side of the first collection box, the second collection box and the third collection box, it is convenient for the operator to observe the capacity inside the first collection box, the second collection box and the third collection box through the glass plate, and to pull the handle in time to take out the full first collection box, the second collection box and the third collection box.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Reference Figure 1-4 A product screening device for intelligent manufacturing of metal materials includes a base 1, a cleaning cylinder 2 fixedly connected to the top of the base 1, a flipping cylinder 3 fixedly connected to one side of the cleaning cylinder 2, a support platform 4 fixedly connected to the top of the cleaning cylinder 2, a first conveyor belt 5 provided on the inner wall of the support platform 4, a bearing sleeve body 6 provided at the top of the first conveyor belt 5, a detection mechanism for detecting bearing sleeve assemblies provided at the top of one side of the base 1, and a rejection component for removing defective bearing sleeve bodies 6 provided on one side of the detection mechanism.

[0039] The top of the flipping cylinder 3 is fixedly connected to a first collection cover 13. The inner wall of the flipping cylinder 3 is provided with a flipping assembly for flipping the bearing sleeve body 6. The first collection cover 13 is located at the bottom of one side of the first conveyor belt 5. The top of the base 1 on the side away from the cleaning cylinder 2 is fixedly connected to a second collection cover 14. The second collection cover 14 is located at the bottom of the rejection assembly. The inner wall of the cleaning cylinder 2 is provided with a cleaning assembly for cleaning the bearing sleeve body 6. The inner wall of the base 1 is provided with a collection assembly for collecting the bearing sleeve body 6.

[0040] To address the issue of inconvenient inspection of the inner wall of the bearing sleeve body 6, when screening of the bearing sleeve body 6 is required, multiple sets of bearing sleeve bodies 6 can be quantitatively conveyed via the first conveyor belt 5, ensuring equal spacing between the sets. When the bearing sleeve bodies 6 are transported to a designated location, the first conveyor belt 5 can be stopped. Subsequently, the multiple equidistant sets of bearing sleeve bodies 6 are inspected by an inspection component. After inspection, qualified bearing sleeve bodies 6 fall into the first collection hood 13. The first collection hood 13 allows the qualified bearing sleeve bodies 6 to be collected downwards into the tilting cylinder 3, where they are then tilted. The assembly flips over qualified bearing sleeve bodies 6, and simultaneously cleans the qualified bearing sleeve bodies 6 during the flipping process using a cleaning component inside the cleaning cylinder 2, removing any residual metal debris from the surface of the bearing sleeve bodies 6. After flipping and cleaning the qualified bearing sleeve bodies 6, they fall into the collection component. A rejection component removes unqualified bearing sleeve bodies 6 into the second collection hood 14, where they fall into the collection component. The collection component then stores the qualified and unqualified bearing sleeve bodies 6 separately.

[0041] Reference Figure 3-6 The detection mechanism includes a bracket 7, which is fixed to the top of one side of the base 1. A hydraulic cylinder 8 is fixed to the top of one side of the bracket 7. A push block 9 is fixed to the output end of the hydraulic cylinder 8. Two sets of cleaning components for cleaning the sleeve 12 are provided on the inner wall of the push block 9. A second conveyor belt 10 is provided at the bottom of the push block 9. An insertion rod 11 is fixed to the top of the second conveyor belt 10. A sleeve 12 is fixed to the outer wall of the insertion rod 11. The sleeve 12 is made of sponge. The outer wall of the sleeve 12 fits against the inner wall of the bearing sleeve body 6. Multiple sets of sleeves 12 are provided and are distributed in parallel on the outer wall of the second conveyor belt 10. The distance between two sets of insertion rods 11 is the same as the distance between two sets of bearing sleeve bodies 6.

[0042] When the first conveyor belt 5 transports multiple sets of equidistant bearing sleeve bodies 6 to a designated location, the hydraulic cylinder 8 can be activated. The hydraulic cylinder 8 pushes the push block 9 downwards, simultaneously causing the second conveyor belt 10 at the bottom of the push block 9 to move downwards as well. Since the spacing between the multiple sets of insertion rods 11 is consistent with the distance between the multiple sets of bearing sleeve bodies 6, it is easy for the insertion rods 11 to be inserted into the inner wall of the bearing sleeve body 6. After the multiple sets of insertion rods 11, which are located on the outer wall of the second conveyor belt 10, are inserted into the inner wall of the multiple sets of bearing sleeve bodies 6, because the ferrule 12 is made of sponge, when the ferrule 12 is inserted into the inner wall and there are irregular protrusions, the irregular protrusions will be stuck on the outer wall of the ferrule 12, increasing the friction between the bearing sleeve body 6 and the ferrule 12. This allows the irregular bearing sleeve body 6 to be pushed into place. The bearing sleeve body 6 is secured to the outer wall of the sleeve 12. Then, the second conveyor belt 10 is activated, causing the second conveyor belt 10 to move multiple sets of insert rods 11 and the sleeve 12 to one side. At the same time, the bearing sleeve body 6 on the outer wall of the sleeve 12 will slide together. When the bearing sleeve body 6 slides to the edge of the first conveyor belt 5, the bearing sleeve body 6 with a flat inner wall will fall downward into the first collection cover 13 due to its own weight. The bearing sleeve body 6 with irregular protrusions on the inner wall will be restricted by the sponge material of the sleeve 12 and will not fall. When the bearing sleeve body 6 with irregular protrusions on the inner wall passes the top of the second collection cover 14, the defective bearing sleeve body 6 will be removed from the outer wall of the sleeve 12 by the rejection component and fall into the second collection cover 14.

[0043] Reference Figure 1-2 The collection assembly includes a first collection box 15, which is disposed at the bottom of the flipping cylinder 3. A guide slope 17 is fixed to the inner wall of the first collection box 15. A third collection box 26 is inserted into the inner wall of the base 1 and disposed at the bottom of the cleaning cylinder 2. A second collection box 16 is disposed on one side of the base 1 and disposed at the bottom of the second collection cover 14. A glass sheet 27 is fixed to the top of one side of each of the first collection box 15, the second collection box 16, and the third collection box 26. A handle 28 is fixed to one side of each of the first collection box 15, the second collection box 16, and the third collection box 26.

[0044] After a qualified bearing sleeve body 6 falls from the flipping cylinder 3, it will fall into the first collection box 15 set on the inner wall of the base 1. By setting a guide slope 17 at the bottom of the first collection box 15, the multi-compartment bearing sleeve bodies 6 can be rolled according to the guidance of the guide slope 17, preventing qualified bearing sleeve bodies 6 from accumulating in one place in the first collection box 15. By setting a third collection box 26 at the bottom of the cleaning cylinder 2, the metal debris cleaned from the qualified bearing sleeve bodies 6 can be collected. By setting a second collection box 16 at the bottom of the second collection cover 14, the unqualified bearing sleeve bodies 6 can be collected, thereby classifying and storing qualified bearing sleeve bodies 6, unqualified bearing sleeve bodies 6, and cleaned metal debris. By setting a glass plate 27 at the top of one side of the first collection box 15, the second collection box 16, and the third collection box 26, the operator can easily observe the capacity inside the first collection box 15, the second collection box 16, and the third collection box 26 through the glass plate 27, so as to take out the first collection box 15, the second collection box 16, and the third collection box 26 when they are full.

[0045] Reference Figure 1-2 The cleaning assembly includes a blower 18, which is fixed to the inner wall of one side of the cleaning cylinder 2. A coarse screen 20 is fixed to the side of the tilting cylinder 3 near the cleaning cylinder 2. A fine screen 19 is fixed to the inner wall of the cleaning cylinder 2. The fine screen 19 is inclined and is located between the second collection box 16 and the blower 18.

[0046] After the qualified bearing sleeve body 6 falls into the tilting cylinder 3, the blower 18 can be started to generate a suction force to one side, thereby sucking the debris in the bearing sleeve body 6 to one side. By setting a coarse screen 20, it is easy to remove the metal debris in the qualified bearing sleeve body 6, and at the same time, the qualified bearing sleeve body 6 is isolated in the tilting cylinder 3. By setting a fine screen 19, the metal debris can be isolated on one side of the fine screen 19. Since the fine screen 19 is set at an angle, when the blower 18 stops working, the metal debris on one side of the fine screen 19 will fall downward into the third collection box 26 by gravity.

[0047] Reference Figure 2-5 The flipping assembly includes a rotary motor 21, which is fixed to the inner wall of the flipping cylinder 3 on the side away from the coarse screen 20. A rotating rod 22 is fixed to the output end of the rotary motor 21. A circular plate 23 is fixed to the outer wall of the rotating rod 22. A partition plate 24 is fixed to the side of the circular plate 23 near the coarse screen 20. Multiple sets of partition plates 24 are arranged and distributed circumferentially on one side of the circular plate 23. A protective pad 25 is fixed to the outer wall of the partition plate 24. The inner wall of the cleaning cylinder 2 is provided with a transmission assembly for improving the filtration efficiency of the fine screen 19.

[0048] When a qualified bearing sleeve body 6 falls into the tilting cylinder 3, it will fall between two sets of adjacent partitions 24. The outer wall of the partition 24 is provided with a rubber protective pad 25 to protect the outer wall of the bearing sleeve body 6. The rotary motor 21 is started, which drives the rotating rod 22 at the output end to rotate. When the rotating rod 22 rotates, it will drive the circular plate 23 to rotate together. The multiple sets of partitions 24 set on the circular plate 23 will also rotate together. Therefore, the position of the bearing sleeve body 6 will change, so that the suction force generated by the fan 18 can clean the bearing sleeve body 6 at different angles, making it easier to clean the metal debris on the outer wall of the bearing sleeve body 6.

[0049] Reference Figure 8-9 The transmission assembly includes an L-shaped rod 35, which is fixed to the side of the circular plate 23 away from the partition plate 24. An opening is provided on one side of the cleaning cylinder 2, which is located on the side of the rotary motor 21. A circular rod 36 is fixed to the inner wall of the opening, and a striking plate 37 is rotatably connected to the outer wall of the circular rod 36. The striking plate 37 penetrates the inner wall of the tilting cylinder 3. A second spring 38 is fixed to the inner wall of the tilting cylinder 3. The second spring 38 is inclined and its bottom is fixed to the top of the striking plate 37. A transmission rod 40 is fixed to one side of the fine screen 19. The side of the transmission rod 40 away from the fine screen 19 extends out of the cleaning cylinder 2. A U-shaped rod 39 is fixed to the side of the transmission rod 40 away from the fine screen 19, and the striking plate 37 is located on the inner wall of the U-shaped rod 39.

[0050] When the circular plate 23 rotates, it drives the L-shaped rod 35 on one side of the circular plate 23 to rotate counterclockwise. When the L-shaped rod 35 moves to the bottom of the striking plate 37, it pushes the side of the striking plate 37 located on the inner wall of the tilting cylinder 3 upward, while simultaneously compressing the second spring 38. The side of the striking plate 37 extending out of the inner wall of the tilting cylinder 3 moves downward and strikes the bottom of the inner wall of the U-shaped rod 39, causing the U-shaped rod 39 to vibrate. This vibration is then transmitted to the fine screen 19 through the transmission rod 40, causing the fine screen to vibrate. The screen 19 vibrates slightly, which helps to shake metal debris off the fine screen 19. As the L-shaped rod 35 continues to rotate upward, it will continue to compress the second spring 38 until the L-shaped rod 35 passes the beater plate 37. Then the second spring 38 pushes the beater plate 37 to reset. The side of the beater plate 37 that extends out of the flipping cylinder 3 will beat the top of the inner wall of the U-shaped rod 39 during the reset, which can make the U-shaped rod 39 vibrate again, thereby improving the efficiency of shaking metal debris off the fine screen 19.

[0051] Reference Figure 6-7The rejection assembly includes a side plate 29, which is fixed to one side of the push block 9. A first spring 30 is fixed to the inner wall of the side plate 29. A push plate is fixed to the bottom of the first spring 30. A lifting plate 31 is fixed to one side of the push plate. The lifting plate 31 is trapezoidal in shape and is located at the top of a set of insert rods 11. A pad 34 is fixed to the bottom of the lifting plate 31. A vertical rod 32 is fixed to one side of the lifting plate 31. A push rod 33 is fixed to the bottom of the vertical rod 32. There are two sets of vertical rods 32 and push rods 33, which are symmetrically distributed on both sides of the lifting plate 31. The two sets of push rods 33 are located on both sides of a set of retaining sleeves 12.

[0052] When a set of insert rods 11 at the top of the second conveyor belt 10 passes the bottom of the lifting plate 31, the trapezoidal shape of the lifting plate 31 allows the insert rods 11 to gradually enter the bottom of the lifting plate 31 along the slope on one side. Simultaneously, this pushes the lifting plate 31 upwards and compresses the first spring 30. As the lifting plate 31 rises, it drives the two sets of vertical rods 32 and push rods 33 on both sides to move upwards together until the lifting plate 31 is pushed to the top. At the same time, the bottom of the push rods 33 is also moved to the top of the outer wall sleeve 12 of the set of insert rods 11 below the second conveyor belt 10. When a set of insert rods 11 at the bottom of the second conveyor belt 10 passes the bottom of the lifting plate 31, a set of insert rods 11 at the top of the second conveyor belt 10 will pass through the bottom of the lifting plate 31. After the bottom of the lifting plate 31 loses its thrust, the first spring 30 will push the push plate and the lifting plate 31 to reset downwards. At the same time as the lifting plate 31 resets, it will drive the vertical rod 32 and the push rod 33 to reset downwards together. Since the push rod 33 is located on both sides of the sleeve 12, when the push rod 33 moves downwards, it will push the unqualified bearing sleeve body 6 on the outer wall of the sleeve 12 downwards, causing the unqualified bearing sleeve body 6 to fall downwards into the second collection cover 14.

[0053] Reference Figure 10-11 The cleaning component includes a support block 41, which is fixed to the inner wall of the push block 9. A cleaning block 42 is fixed to the side of the support block 41 away from the push block 9. A brush 43 is fixed to the side of the cleaning block 42 away from the support block 41. The brush 43 is disposed on one side of a set of card sleeves 12.

[0054] As the insertion rod 11 and the ferrule 12 move with the second conveyor belt 10, they pass through the inner wall of the push block 9. The two sets of cleaning blocks 42 and brushes 43 provided on the inner wall of the push block 9 clean the outer wall of the ferrule 12 as it passes through the inner wall of the push block 9, thus scraping off the metal debris adhering to the outer wall of the ferrule 12.

[0055] Reference Figure 10-11The cleaning block 42 has an air intake hole 44 on the side near the brush 43. Multiple sets of air intake holes 44 are arranged in parallel on one side of the cleaning block 42. A transmission pipe 45 is fixed to the inner wall of the support block 41. The transmission pipe 45 is located on one side of the air intake hole 44. The transmission pipe 45 is a telescopic pipe. The bottom of the transmission pipe 45 extends into the inner wall of the cleaning cylinder 2. An air intake hood 46 is fixed to the side of the transmission pipe 45 that extends into the inner wall of the cleaning cylinder 2. The bottom of the transmission pipe 45 and the air intake hood 46 are located between the fine screen 19 and the coarse screen 20.

[0056] When the cleaning block 42 and the brush 43 clean the outer wall of the sleeve 12, the bottom of the transmission tube 45 is located on the inner wall of the cleaning cylinder 2, and the bottom of the transmission tube 45 is provided with a suction hood 46 for expanding the suction power, so suction power can be provided to the transmission tube 45. The top of the transmission tube 45 is installed in the support block 41, so the suction power in the transmission tube 45 will extend out through the suction hole 44 opened on the cleaning block 42, which can adsorb the scraped fine metal debris into the inner wall of the cleaning block 42 and suck it into the transmission tube 45, so that the fine metal debris is sucked into the flipping cylinder 3.

[0057] Working Principle: To address the issue of inconvenient inspection of the inner wall of the bearing sleeve body 6, when screening of the bearing sleeve body 6 is required, multiple sets of bearing sleeve bodies 6 can be quantitatively conveyed via the first conveyor belt 5, ensuring equal spacing between them. When the bearing sleeve body 6 is transported to the designated location, the first conveyor belt 5 can be stopped, and then the hydraulic cylinder 8 is activated. The hydraulic cylinder 8 pushes the push block 9 downwards, simultaneously moving the second conveyor belt 10 at the bottom of the push block 9 downwards as well. Since the spacing of the multiple sets of insertion rods 11 matches the distance between the multiple sets of bearing sleeve bodies 6, it is easy for the insertion rods 11 to be inserted into the inner wall of the bearing sleeve body 6. After the multiple sets of insertion rods 11, which are set on the outer wall of the second conveyor belt 10, are inserted into the inner wall of the multiple sets of bearing sleeve bodies 6, the clamping sleeve... Material 12 is made of sponge. Therefore, when the irregular protrusions on the inner wall of the sleeve 12 are inserted, the irregular protrusions will be stuck on the outer wall of the sleeve 12, increasing the friction between the bearing sleeve body 6 and the sleeve 12. This allows the irregularly shaped bearing sleeve body 6 to be stuck on the outer wall of the sleeve 12. Then, the second conveyor belt 10 is started, causing multiple sets of insertion rods 11 and sleeves 12 to move to one side. At the same time, the bearing sleeve body 6 on the outer wall of the sleeve 12 will slide together. When the bearing sleeve body 6 slides to the edge of the first conveyor belt 5, the bearing sleeve body 6 with a flat inner wall will fall downwards into the first collection cover 13 due to its own weight, and then fall downwards into the tilting cylinder 3, until it falls between two sets of adjacent partitions 24. The outer wall of the partition 24 is made of rubber. The rubber protective pad 25 protects the outer wall of the bearing sleeve body 6. Starting the rotary motor 21 and the fan 18 causes the fan 18 to generate a suction force to one side, thus drawing metal debris from the bearing sleeve body 6 to one side. A coarse screen 20 facilitates the removal of qualified metal debris from the bearing sleeve body 6, while simultaneously isolating the qualified bearing sleeve body 6 within the tilting cylinder 3. A fine screen 19 isolates the metal debris on one side of the fine screen 19. Simultaneously, the rotary motor 21 drives the output rod 22 to rotate counterclockwise. The rotation of the rod 22 causes the circular plate 23 to rotate as well, and the multiple sets of partitions 24 on the circular plate 23 also rotate, thus changing the position of the bearing sleeve body 6, facilitating airflow. The suction force generated by the machine 18 cleans the bearing sleeve body 6 at different angles, facilitating the removal of metal debris from the outer wall of the bearing sleeve body 6. When the circular plate 23 rotates, it drives the L-shaped rod 35 on one side of the circular plate 23 to rotate counterclockwise. When the L-shaped rod 35 moves to the bottom of the striking plate 37, it lifts the side of the striking plate 37 located on the inner wall of the tilting cylinder 3 upwards, simultaneously compressing the second spring 38. The side of the striking plate 37 extending out of the inner wall of the tilting cylinder 3 moves downwards and strikes the bottom of the inner wall of the U-shaped rod 39, causing the U-shaped rod 39 to vibrate. This vibration is transmitted to the fine screen 19 via the transmission rod 40, causing the fine screen 19 to vibrate slightly, thus helping to shake off metal debris from the fine screen 19. As the L-shaped rod 35 continues to rotate upwards...The second spring 38 will continue to be compressed until the L-shaped rod 35 passes the striking plate 37. Then, the second spring 38 pushes the striking plate 37 to reset. The side of the striking plate 37 extending out of the tilting cylinder 3 will strike the top of the inner wall of the U-shaped rod 39 during reset, causing the U-shaped rod 39 to vibrate again, thereby improving the efficiency of shaking metal debris off the fine screen 19. Since the fine screen 19 is tilted, when the fan 18 stops working, the metal debris on one side of the fine screen 19 will fall downwards into the third collection box 26 due to gravity. After the qualified bearing sleeve body 6 falls from the tilting cylinder 3, it will fall into the first collection box 15 located on the inner wall of the base 1. By providing a guide slope 17 at the bottom of the first collection box 15, the multi-compartment bearing sleeve bodies 6 can roll according to the guide slope 17, preventing the qualified bearing sleeve bodies 6 from accumulating in one place in the first collection box 15.

[0058] The bearing sleeve body 6, with irregular protrusions on its inner wall, is restrained by the sponge-material retainer 12, preventing it from falling off. As the bearing sleeve body 6 passes the top of the second collecting cover 14, the insert rod 11 gradually slides down the slope of the lifting plate 31 to the bottom of the lifting plate 31, simultaneously lifting the lifting plate 31 upwards and compressing the first spring 30. As the lifting plate 31 rises, it drives the two sets of vertical rods 32 and push rods 33 on both sides to move upwards together until the lifting plate 31 is pushed to the top. At the same time, the bottom of the push rod 33... The position is also moved to the top of the outer wall sleeve 12 of a set of insert rods 11 below the second conveyor belt 10. When the set of insert rods 11 at the bottom of the second conveyor belt 10 passes the bottom of the lifting plate 31, the set of insert rods 11 at the top of the second conveyor belt 10 will pass through the bottom of the lifting plate 31. After the bottom of the lifting plate 31 loses its thrust, the first spring 30 will push the push plate and the lifting plate 31 to reset downwards. At the same time as the lifting plate 31 resets, it will also drive the vertical rod 32 and the push rod 33 to reset downwards together. Since the push rod 33 is located on both sides of the sleeve 12, when the push rod 33 moves downwards, it will... The defective bearing sleeve body 6 on the outer wall of the ferrule 12 is pushed downwards, causing it to fall into the second collection hood 14. A second collection box 16 at the bottom of the second collection hood 14 collects the defective bearing sleeve body 6. As the insertion rod 11 and ferrule 12 continue to move with the second conveyor belt 10, they pass through the inner wall of the push block 9. Two sets of cleaning blocks 42 and brushes 43 on the inner wall of the push block 9 clean the outer wall of the ferrule 12 as it passes through, scraping away any metal debris adhering to the outer wall of the ferrule 12. In addition, since the bottom of the transmission pipe 45 is located on the inner wall of the cleaning cylinder 2, and the bottom of the transmission pipe 45 is provided with a suction hood 46 for expanding the suction force, it can provide suction force for the transmission pipe 45. The top of the transmission pipe 45 is installed in the support block 41, so the suction force in the transmission pipe 45 will extend out through the suction hole 44 opened on the cleaning block 42, which can adsorb the scraped fine metal debris into the inner wall of the cleaning block 42 and suck it into the transmission pipe 45, so that the fine metal debris is sucked into the rotating cylinder 3 and blocked again by the fine screen 19, and finally falls into the third collection box 26.
