Description

Technical Field

[0001] This utility model relates to the field of floor drain polishing technology, specifically to an automated device for polishing the surface of floor drains. Background Technology

[0002] A floor drain is a drainage device installed on the ground or floor surface, primarily used to remove standing water from indoor floors. It typically consists of the drain body, a grate, and a water trap. The drain grate filters hair, debris, and other imperfections, preventing them from clogging the drain pipes.

[0003] In existing technologies, the production of floor drains involves multiple processes, including polishing. Polishing is a crucial step in the floor drain production process, and its importance cannot be underestimated. Polished floor drains not only have a smoother surface but also effectively improve their corrosion resistance. A smooth surface reduces the adhesion of dirt and impurities, lowering the risk of corrosion due to long-term use.

[0004] However, the lack of an efficient and stable internal fixing structure during the polishing process makes it difficult for the floor drain to maintain a stable position when subjected to polishing pressure. This causes the floor drain to easily shift, shake, or deviate due to external impacts during the polishing process. Once the position of the floor drain changes, the contact state between the polishing tool and the floor drain surface becomes unstable, directly causing uneven polishing, which seriously affects the flatness and smoothness of the floor drain surface, thereby reducing product quality and increasing the defect rate. To address this, we propose an automated device for polishing the surface of floor drains. Utility Model Content

[0011] In some embodiments, the bottom end of the fixing tube is fixedly connected to the inner wall of the sub-disc, the top side of the sub-disc is in contact with the bottom side of the mother disc, a magnet is provided on the inner wall of the sub-disc, the inner wall of the sub-disc is in contact with the outer side of the magnet, and the inner side of the magnet is in contact with the outer side of the fixing tube.

[0015] 1. Place the four drain bodies one by one on the fixed pipe, start the motor to make the gear ring start rotating. During the rotation, the four gears will mesh synchronously, causing the connecting rod to start rotating. Then, the pressing plate applies external force to the inner rod in the fixed pipe by using the inclined surface during the rotation. Naturally, the inner rod will move synchronously in the fixed pipe. There are four inner rods, each connected to a backing plate. As they move, the backing plates will contact the inside of the drain body, thus fixing the drain body from the inside. This ensures that the drain body maintains a stable position when facing the pressure applied by the grinding tool during the grinding process.

[0016] 2. Start the grinding equipment in the top plate. At this time, by extending the telescopic rod at the bottom of the sub-plate, the drain body is raised to a higher position, allowing the drain body to contact the grinding equipment. Then, the four drain bodies can be ground simultaneously. Because the grinding disc of the grinding equipment is circular, the pressure between the drain body and the grinding equipment can be increased by adjusting the extension length of the telescopic rod.

One side of the limit plate 18 is fixedly connected to the other end of the limit plate 18. One end of the limit plate 18 is fixedly connected to the inner wall of the fixed tube 13. The bottom end of the connecting rod 14 is rotatably connected through the inner wall of the sub-disc 11. A motor 113 is provided on the inner wall of the sub-disc 11. One end of the motor 113 is fixedly connected to the outer side of the inner wall of the sub-disc 11. A gear ring 111 is provided at the output end of the motor 113. The output end is fixedly connected to the center of the gear ring 111. A gear 110 is provided on the outer side of the gear ring 111. The outer side of the gear ring 111 and the outer side of the gear 110 are rotatably meshed. The top side of the gear 110 is fixedly connected to the bottom end of the connecting rod 14. A drain body 114 is provided on one side of the plate 19. One side of the plate 19 contacts the inner side of the drain body 114. One side of the drain body 114 contacts the inner wall of the mother plate 12. The bottom end of the fixing tube 13 is fixedly connected to the inner wall of the daughter plate 11. The top side of the daughter plate 11 contacts the bottom side of the mother plate 12. A magnet 115 is provided on the inner wall of the daughter plate 11. The inner wall of 1 is in contact with the outer side of magnet 115, the inner side of magnet 115 is in contact with the outer side of fixed tube 13, a telescopic rod 112 is provided on the bottom side of sub-disc 11, the bottom side of sub-disc 11 is fixedly connected to the top of telescopic rod 112, a base plate 116 is provided at the bottom end of telescopic rod 112, the bottom end of telescopic rod 112 is fixedly connected to the top side of base plate 116, a top plate 117 is provided on one side of base plate 116, one side of base plate 116 is fixedly connected to the side of top plate 117, a grinding device 118 is provided on the bottom side of top plate 117, and the bottom side of top plate 117 is fixedly connected to one end of the top side of the center of grinding device 118.

[0026] In use, this automated drain surface grinding and polishing device employs a sub-disc 11 designed to stably withstand the grinding pressure on the drain body 114 during the grinding process. The sub-disc 11 has four fixed tubes 13, each containing identical components. By placing the four drain bodies 114 one by one onto the fixed tubes 13, and starting the motor 113 (which houses the inner wall of the sub-disc 11), the gear ring 111 begins to rotate. During this rotation, the four gears 110 mesh synchronously. A connecting rod 14 is connected to the top of each gear 110 and is located within the fixed tube 13, allowing the connecting rod 14 to open... When the rotation begins, a pressing plate 15 is fixedly connected to the top of the connecting rod 14. Then, during the rotation, the pressing plate 15 applies external force to the inner rod 16 in the fixed tube 13 by using the inclined surface. Naturally, the inner rod 16 will move synchronously in the fixed tube 13. There are four inner rods 16, each of which is connected to a backing plate 19. As they move continuously, the backing plate 19 will contact the inner side of the drain body 114, thereby fixing the drain body 114 internally. This ensures that the drain body 114 maintains a stable position when facing the pressure applied by the grinding tool during the grinding process, and will not be displaced, shaken or shifted due to external impact. This effectively avoids problems such as uneven grinding and missed grinding.

[0027] After the fixing work is completed, a top plate 117 is designed above the mother plate 12. By activating the grinding device 118 in the top plate 117, the length of the telescopic rod 112 at the bottom of the daughter plate 11 is extended, so that the drain body 114 is raised on the original basis, and the drain body 114 comes into contact with the grinding device 118. Then, the four drain bodies 114 can be ground synchronously. Since the grinding disc of the grinding device 118 is circular, the pressure between the drain body 114 and the grinding device 118 can be increased by adjusting the extension length of the telescopic rod 112.

[0028] Secondly, once completed, the rotation of the motor 113 causes the gear ring 111 to reverse, and the pressing plate 15 no longer exerts external force on the inner rod 16. At this time, since a spring piece 17 is designed in the inner rod 16, and a limit plate 18 is fixed at the other end of the spring piece 17, the energy release of the spring piece 17 causes the inner rod 16 to retract, so that the backing plate 19 no longer exerts a fastening force on the drain body 114. The limit plate 18 can allow the inner rod 16 to move in a specified path during the movement of the inner rod 16, avoiding the drain body 114 from becoming loose due to uneven fastening force.

[0029] Finally, a magnet 115 is designed in the sub-panel 11. Under the action of the magnet 115, the iron filings generated during the grinding process can be attracted. When grinding the drain body 114, the iron filings will fly everywhere. If they are not cleaned up in time, they will not only be scattered on the workbench, but may also diffuse into the air. The magnet 115 firmly attracts the iron filings, preventing them from scattering and preventing workers from inhaling iron filings, thus protecting the health of the operators.

[0030] Example 2: Please refer to Figure 1 The disassembly mechanism 2 includes a side plate 21. The upper and lower ends of the side plate 21 are respectively provided with a sub-plate 11 and a mother plate 12. The upper and lower ends of the side plate 21 are respectively engaged with the inner walls of the sub-plate 11 and the mother plate 12. The inner wall of the side plate 21 is provided with a bolt 22. The inner wall of the side plate 21 is rotatably connected to the outer thread of the bolt 22. One end of the bolt 22 is rotatably connected to the inner thread of the mother plate 12.

[0031] After the daughter disk 11 and the mother disk 12 are connected, the side plate 21 is inserted into the inner wall of both disks. Then, bolts 22 are used to connect the side plate 21 to the mother disk, thereby fixing the daughter disk 11 and the mother disk 12 and preventing them from shifting in their corresponding positions. Then, in the opposite manner, the bolts 22 are removed, and the side plate 21 is moved out of the daughter disk 11 and the mother disk 12. At this point, the daughter disk 11 and the mother disk 12 are separated, fully exposing the magnet 115. This allows workers to clean the iron filings thoroughly and without any blind spots. If the iron filings are not cleaned, the adsorption performance of the magnet 115 will be affected.

[0032] Please see Figures 1-5Four drain bodies 114 are placed one by one on the fixed pipe 13. Since a motor 113 is designed inside the inner wall of the sub-plate 11, starting the motor 113 causes the gear ring 111 to rotate. During rotation, the four gears 110 mesh synchronously. A connecting rod 14 is connected to the top of each gear 110. The connecting rod 14 is located in the fixed pipe 13, causing it to rotate. A pressing plate 15 is fixedly connected to the top of the connecting rod 14. During rotation, the pressing plate 15 applies external force to the inner rod 16 in the fixed pipe 13 using its inclined surface. Naturally, the inner rod 16 will move synchronously within the fixed pipe 13. There are four inner rods 16, each connected to a backing plate 19. As the backing plates 19 move continuously, they will contact the floor... The inner side of the drain body 114 is contacted, thereby fixing the drain body 114 internally. This ensures that the drain body 114 maintains a stable position when facing the pressure applied by the grinding tool during the grinding process. Then, the grinding device 118 in the top plate 117 is started. At this time, by extending the length of the telescopic rod 112 at the bottom of the sub-plate 11, the drain body 114 is raised to a higher position than before, so that the drain body 114 contacts the grinding device 118. This allows the four drain bodies 114 to be ground synchronously. Since the grinding disc of the grinding device 118 is annular, the pressure between the drain body 114 and the grinding device 118 can be increased by adjusting the extension length of the telescopic rod 112.

[0033] Insert the side plate 21 into the inner wall of both, and then use bolts 22 to connect the side plate 21 to the mother plate, thereby fixing the daughter plate 11 and the mother plate 12 so that they will not shift after they are in the corresponding positions. At the same time, in the opposite way, remove the bolts 22 and move the side plate 21 out of the daughter plate 11 and the mother plate 12. At this time, the daughter plate 11 and the mother plate 12 are separated, so that the magnet 115 is fully exposed, which makes it easy for the staff to clean the iron filings from all directions without dead corners.
