Description

Technical Field

[0001] The utility model relates to the technical field of metal part polishing, in particular to an automatic polishing device for metal parts. Background Technique

[0002] During the long-term storage of small parts such as screws, their outer surfaces will rust or adhere to other substances. When polishing metal parts such as screws, a polishing device is required.

[0003] In the patent application with the authorization publication number CN211163442U, the authorization publication date of August 4, 2020, and the name "A Metal Surface Treatment and Polishing Device", it includes a frame. Inside the frame, a collection tank and a sieve frame are successively connected from bottom to top. On one outer wall of the frame, a motor A is fixedly connected. The power output end of the motor A is sleeved with a synchronous belt, and a power box is sleeved outside the synchronous belt. The other end of the synchronous belt is sleeved on a gear reducer, and the gear reducer is fixedly connected to one side of the top of the frame. The utility model provides a metal surface treatment and polishing device. By providing a sieve mesh and a sieve frame, the polished metal material inside the drum is poured out from the discharge port and rolls down along the inclined sieve mesh. The vibration motor on one side of the frame is energized to drive the frame and the sieve mesh to vibrate, accelerating the separation of the metal and abrasive materials such as steel sand. The abrasive materials sifted through the sieve mesh fall into the collection tank and are collected for reuse.

[0004] Although the existing metal part polishing device can polish metal parts and collect the abrasive materials falling into the collection tank for reuse, it is found in use that the metal part polishing device can only polish metal parts in batches. After polishing, manual loading and unloading are required. During loading and unloading, the polishing device cannot continue to work, which not only requires manual assistance and cannot automatically complete the polishing of metal parts, but also has low working efficiency and is inconvenient to use. Therefore, we propose an automatic polishing device for metal parts to solve the problems raised above. Content of the Utility Model

[0016] 3. Beneficial effects:

[0017] Adopting the technical solution provided by the present utility model, compared with the prior art, the automatic polishing device for metal parts of the present utility model is as follows:

[0018] (1) The conveyor belt transports the metal parts into the flow channel. Abrasives are arranged in the flow channel. The vibration mechanism drives the vibrating disk to vibrate, causing the vibrating disk to drive the metal parts and the abrasives to move spirally downward in the flow channel through vibration. During the movement, the surface of the metal parts is polished by the abrasives. The polished metal parts fall into the discharge port along with the abrasives, and then fall into the filter box. Through the screening mechanism arranged in the filter box, the metal parts and the abrasives are screened. The metal parts fall onto the conveyor belt through the discharge port and the discharge hopper, and the abrasives enter the return cylinder. The screw rod drives the abrasives to move upward and re-enter the flow channel through the discharge pipe. With this polishing device and in cooperation with the conveyor belt, the polishing of metal parts can be automatically completed, and the metal parts can be polished continuously, effectively improving the polishing efficiency of metal parts.

[0019] (2) After the parts, abrasives, and rust blocks fall into the filter box, they are preliminarily screened by the filter screen. The parts flow along the inclined filter screen towards the discharge port, while the abrasives and rust blocks fall onto the guide plate through the mesh holes of the filter screen and flow towards the magnetic roller along the inclined guide plate. At the same time, the second motor drives the magnetic roller to rotate. For the abrasives and rust blocks passing through the magnetic roller, the rust blocks are adsorbed onto the surface of the magnetic roller, while the abrasives continue to flow and fall from the end of the guide plate, and then fall to the bottom of the filter box. When the magnetic roller rotates, the rust blocks attached to the magnetic roller are scraped off by the scraping plate and flow into the slag collection box along the scraping plate. Through the arranged screening mechanism, the parts, abrasives, and rust blocks can be screened.

[0020] (2) The screened abrasives fall to the bottom of the filter box, enabling the abrasives to enter the return cylinder through the inclined feed pipe. At the same time, the first motor drives the screw rod to rotate, driving the abrasives in the return cylinder to move upward and re-falling into the flow channel through the inclined discharge pipe, so that the abrasives can be recycled.

A filter box 9 is installed in the middle of the top end of the base 1. An inlet port 10 is opened in the middle of the top end of the filter box 9. The discharge port 4 and the inlet port 10 are connected and communicated through a connecting hose 11. A discharge port 12 is opened at one end of the filter box 9 near the upper part. A discharge hopper 13 is installed outside the filter box 9 corresponding to the discharge port 12;

[0033] A return material cylinder 14 is installed at the top of one end of the base 1 away from the discharge hopper 13. A spiral rod 15 is rotatably connected inside the return material cylinder 14. A first motor 16 is installed at the top end of the return material cylinder 14. The shaft end of the first motor 16 is fixedly connected to the spiral rod 15. The middle part of the bottom end of the filter box 9 is connected and communicated with the return material cylinder 14 through a feed pipe 17. One side of the return material cylinder 14 near the upper part of the vibrating bowl 2 is communicated with a discharge pipe 18. A screening mechanism is arranged inside the filter box 9;

[0034] The conveyor belt conveys the metal parts into the runner 3. Abrasives are arranged in the runner 3. The vibrating mechanism drives the vibrating bowl 2 to generate vibration, so that the vibrating bowl 2 drives the metal parts and the abrasives to move downward in a spiral shape in the runner 3 through vibration. During the movement, the surface of the metal parts is polished by the abrasives. The polished metal parts fall into the discharge port 4 along with the abrasives, and then fall into the filter box 9. Through the screening mechanism arranged in the filter box 9, the metal parts and the abrasives are screened. The metal parts fall onto the conveyor belt through the discharge port 12 and the discharge hopper 13. The abrasives enter the return material cylinder 14, and the spiral rod 15 drives the abrasives to move upward and re-enter the runner 3 through the discharge pipe 18.

[0035] Please refer to Figures 1 to 5, the vibration mechanism includes a first leg 5. The first legs 5 are fixedly connected to the top of the base 1 near the ring side at equal intervals. A second leg 6 is fixedly connected to the bottom of the vibration disk 2 corresponding to the first leg 5. A spring 7 is fixedly installed between the first leg 5 and the second leg 6. Vibration motors 8 are symmetrically installed at the bottom of both sides of the vibration disk 2. The middle of the top end of the first leg 5 is fixedly connected to a guide frame 26. A guide groove 27 is formed at the top of the guide frame 26. A guide rod 28 is fixedly connected to the bottom of the second leg 6 corresponding to the guide groove 27. The spring 7 is sleeved outside the guide frame 26 and the guide rod 28. The feed pipe 17 is arranged obliquely downward from the filter box 9 to the return cylinder 14. The discharge pipe 18 is arranged obliquely downward from the return cylinder 14 to the vibration disk 2. And the opening at one end of the discharge pipe 18 away from the return cylinder 14 is located above the flow channel 3. The vibration disk 2 is connected to the base 1 through the spring 7 to form a flexible connection. Thus, when the vibration motors 8 work, they drive the vibration disk 2 to vibrate, so as to polish the metal parts. At the same time, through the guiding structure formed by the guide frame 26 and the guide rod 28, the vibration of the vibration disk 2 is guided, and the spring 7 can be supported at the same time to prevent the spring 7 from being distorted. And the screening mechanism screens the parts, abrasives and rust blocks. The screened abrasives fall to the bottom of the filter box 9, so that the abrasives enter the return cylinder 14 through the inclined feed pipe 17. At the same time, the first motor 16 drives the screw rod 15 to rotate, driving the abrasives in the return cylinder 14 to move upward, and re-falling into the flow channel 3 through the inclined discharge pipe 18, so as to recycle the abrasives.

[0036] Please refer to Figures 1 to 5, the screening mechanism includes a filter screen 19. The filter screen 19 is installed inside the filter box 9 corresponding to the discharge port 12. A guide plate 20 is installed inside the filter box 9 near the lower part of the filter screen 19. A magnetic roller 21 is rotatably connected above the end of the filter box 9 near the guide plate 20. A second motor 22 is installed outside the filter box 9 corresponding to the magnetic roller 21. The shaft end of the second motor 22 is fixedly connected to the magnetic roller 21. A slag discharge port 23 is opened at the end of the filter box 9 corresponding to the magnetic roller 21. A scraping plate 24 is installed inside the slag discharge port 23. A slag collection box 25 is installed at the end of the base 1 corresponding to the scraping plate 24. Both the filter screen 19 and the guide plate 20 are inclined. The filter screen 19 is inclined downward in the direction of the discharge port 12, and the inclination directions of the filter screen 19 and the guide plate 20 are opposite. One end of the scraping plate 24 close to the magnetic roller 21 has a conical cross-section, and the scraping plate 24 abuts against the outer surface of the magnetic roller 21 through the conical end. After the parts, abrasives, and rust blocks fall into the filter box 9, they are preliminarily screened by the filter screen 19, so that the parts flow along the inclined filter screen 19 in the direction of the discharge port 12, while the abrasives and rust blocks fall onto the guide plate 20 through the mesh holes of the filter screen 19 and flow along the inclined guide plate 20 in the direction of the magnetic roller 21. At the same time, the second motor 22 drives the magnetic roller 21 to rotate. Among the abrasives and rust blocks passing through the magnetic roller 21, the rust blocks are adsorbed onto the surface of the magnetic roller 21, while the abrasives continue to flow and fall from the end of the guide plate 20, and then fall to the bottom of the filter box 9. When the magnetic roller 21 rotates, the rust blocks attached to the magnetic roller 21 are scraped off by the scraping plate 24 and flow into the slag collection box 25 along the scraping plate 24. Through the set screening mechanism, the parts, abrasives, and rust blocks can be screened.

[0037] Working principle: When using this automatic polishing device for metal parts, as Figures 1 to 4 shown, first, the conveyor belt transports the metal parts into the flow channel 3. Abrasives are arranged in the flow channel 3. The vibration mechanism drives the vibration disk 2 to vibrate, so that the vibration disk 2 drives the metal parts and abrasives to move spirally downward in the flow channel 3 through vibration. During the movement, the surface of the metal parts is polished by the abrasives. The polished metal parts fall into the discharge port 4 along with the abrasives, and then fall into the filter box 9. Through the screening mechanism arranged in the filter box 9, the metal parts and abrasives are screened. The metal parts pass through the discharge port 12 and the discharge hopper 13 and fall onto the conveyor belt, and the abrasives enter the return material cylinder 14. The spiral rod 15 drives the abrasives to move upward and re-enter the flow channel 3 through the discharge pipe 18. Through this polishing device, in cooperation with the conveyor belt, the polishing of metal parts can be automatically completed, and the metal parts can be polished continuously, effectively improving the polishing efficiency of metal parts;

[0038] After the parts, abrasives and rust blocks fall into the filter box 9, they are preliminarily screened through the filter screen 19, so that the parts flow along the inclined filter screen 19 towards the discharge port 12, while the abrasives and rust blocks fall onto the diversion plate 20 through the mesh holes of the filter screen 19 and flow along the inclined diversion plate 20 towards the magnetic roller 21. At the same time, the second motor 22 drives the magnetic roller 21 to rotate. For the abrasives and rust blocks passing through the magnetic roller 21, the rust blocks are adsorbed onto the surface of the magnetic roller 21, while the abrasives continue to flow and fall from the end of the diversion plate 20 and then onto the bottom of the filter box 9. When the magnetic roller 21 rotates, the rust blocks attached to the magnetic roller 21 are scraped off by the scraping plate 24 and flow along the scraping plate 24 into the slag collection box 25. Through the provided screening mechanism, the parts, abrasives and rust blocks can be screened. The screened abrasives fall onto the bottom of the filter box 9, and the abrasives enter the return cylinder 14 through the inclined feed pipe 17. At the same time, the first motor 16 drives the screw rod 15 to rotate, driving the abrasives in the return cylinder 14 to move upward and re-falling into the flow channel 3 through the inclined discharge pipe 18, so that the abrasives can be recycled.

[0039] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
