Description

Technical Field

[0001] This invention belongs to the field of polishing equipment technology, specifically a device for rapid grinding, polishing and quality inspection of reflective glass beads for highway tunnels. Background Technology

[0002] As a crucial component of transportation infrastructure, highway tunnels rely heavily on their lighting and safety warning systems. Reflective glass beads, a key element in reflective marking materials for highway tunnels, significantly improve visibility within the tunnel by reflecting vehicle headlights back to the driver's eyes, effectively enhancing driving safety. In practical applications, the performance indicators of reflective glass beads, especially their surface smoothness and reflectivity, directly determine the warning effect of reflective markings. Therefore, meticulous grinding and polishing of reflective glass beads to meet their stringent optical performance requirements has become a critical step in ensuring traffic safety in highway tunnels.

[0003] In actual production, multi-stage polishing is often required to achieve ideal optical performance of reflective glass beads. Existing methods typically involve using multiple independent polishing devices. After the first stage of polishing, the glass beads need to be removed from the current device, undergo intermediate processing such as manual cleaning, and then transferred to another polishing device for the next stage of polishing. However, using multiple devices for graded polishing not only requires more investment in equipment but also occupies more production space, increasing the company's production costs and operational pressure. At the same time, the transfer of glass beads also increases the workload of operators and affects product production efficiency.

[0004] Therefore, the present invention provides a device for rapid grinding, polishing and quality inspection of reflective glass beads for highway tunnels. Summary of the Invention

[0009] Preferably, the baffle assembly A includes two slide rods, each slidably mounted on the inner wall of the lower support. One end of each slide rod is fixedly mounted with a limiting plate, which is in contact with the upper support. The other end of each slide rod is fixedly mounted with a connecting block B. A middle baffle is fixedly mounted between the inner walls of the two connecting blocks B. The middle baffle overlaps the top of the polishing disc. The annular filter plate is located between the middle baffle and the inner baffle.

[0010] Preferably, the rotating assembly includes a rotating seat, the inner wall of which is rotatably connected to the outer wall of the turntable, a drive motor is fixedly installed at the bottom of the rotating seat, the output shaft of the drive motor passes through the rotating seat and is fixedly connected to the turntable, and a plurality of columns are evenly fixedly installed at the bottom of the rotating seat, the ends of the columns away from the rotating seat being fixedly connected to the inner wall of the chip discharge hopper A.

[0011] Preferably, the cross-section of the polishing plate is recessed, a collection box is fixedly installed on the outer wall of the chip discharge hopper A, the collection box is located outside the polishing disc, the bottom of the collection box is inclined, and a baffle assembly B is provided on the outer side of the polishing disc.

[0012] Preferably, the baffle assembly B includes a connecting block C, and two connecting blocks C are provided. The two connecting blocks C are respectively fixedly installed on the ends of the two lower supports away from the connecting block A. An outer baffle is fixedly installed between the inner walls of the two connecting blocks C, and the inner wall of the outer baffle is slidably connected to the outer wall of the polishing disc.

[0013] Preferably, a guide box is fixedly installed on one side of the collection box, a square filter plate is fixedly installed on the inner wall of the guide box, and a chip discharge hopper B is fixedly installed at the bottom of the guide box, with the chip discharge hopper B located below the square filter plate.

[0014] Preferably, a base is provided below the chip discharge hopper A, and a plurality of support legs are fixedly installed on the top of the base, with the ends of the support legs away from the base being fixedly connected to the chip discharge hopper A.

A discharge box is fixedly installed at one end of the test tank, and a feed box is fixedly installed at the other end of the test tank. The feed box is connected to a guide box.

[0016] The beneficial effects of this invention are as follows: 1. This invention divides the polishing area into two parts: coarse polishing and fine polishing, by setting a "cone"-shaped coarse polishing plate at the center of the polishing disc and a fine polishing plate located outside the coarse polishing plate. This allows the glass beads to undergo preliminary coarse polishing on the coarse polishing plate to remove larger imperfections and rough parts on the surface, and then slide onto the fine polishing plate for fine polishing, further improving the smoothness and reflectivity of the glass bead surface, thus realizing a graded polishing function in one device.

[0017] 2. This invention features an annular filter plate between the coarse polishing area and the fine polishing area, which can accurately separate glass beads from coarse polishing debris. When the glass beads have completed coarse polishing and are distributed above the annular filter plate under the obstruction of the inner baffle and the material blocking component A, the polishing disc rotates, causing the glass beads to move. At this time, the fine debris generated by coarse polishing can pass through the annular filter plate, while the glass beads are effectively blocked above the filter plate, ensuring the complete separation of debris and glass beads and providing a clean environment for subsequent fine polishing.

[0018] 3. After the polishing work is completed, the automatic telescopic rod retracts, causing the inner baffle to move up. The material blocking component B then releases the restriction on the finely polished glass beads. While the polishing disc rotates to clean the coarsely polished glass beads, the finely polished glass beads will be thrown out under the action of centrifugal force. This automatic feeding method does not require manual intervention, which greatly improves production efficiency and reduces errors and labor intensity caused by manual operation.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 9As shown in the embodiment of the present invention, a rapid grinding and polishing device for reflective glass beads in highway tunnels includes a polishing disc 1. A coarse polishing plate 2, which is conical in shape, is fixedly installed at the center of the polishing disc 1. A fine polishing plate 3, which is annular in shape and located outside the coarse polishing plate 2, is fixedly installed on the inner wall of the polishing disc 1. An inner baffle 4 is provided at the top of the polishing disc 1, and a lifting assembly is provided above the inner baffle 4 to drive the inner baffle 4 to move up and down. A turntable 5 is fixedly installed at the bottom of the polishing disc 1, and a rotating assembly is provided below the turntable 5 to drive the turntable 5 to rotate. During polishing, the glass beads to be polished are placed inside the inner baffle 4. The glass beads inside the inner baffle 4 will be located on the coarse polishing plate 2. After the polishing medium is introduced, the rotating assembly is activated, which drives the polishing disc 1 to rotate. The coarse polishing plate 2 rotates along with the polishing disc 1 to coarsely polish the glass beads. After the glass beads have completed coarse polishing, the lifting assembly raises the inner baffle 4. Since the coarse polishing plate 2 is conical, the glass beads slide down the inclined surface of the inner baffle 4 onto the fine polishing plate 3 after being unrestrained by the inner baffle 4. After the finely polished glass beads slide down onto the fine polishing plate 3, the lifting assembly lowers the inner baffle 4. At this time, a new glass bead is introduced into the inner side of the inner baffle 4, and the rotating assembly is activated. Under the action of the rotating assembly, the polishing disc 1 drives the coarse polishing plate 2 and the fine polishing plate 3 to rotate together, achieving synchronous coarse and fine polishing. In summary, this invention achieves this by setting a conical shape at the center of the polishing disc 1. The coarse polishing plate 2 and the fine polishing plate 3 located outside the coarse polishing plate 2 divide the polishing area into coarse and fine polishing sections. This allows the glass beads to undergo preliminary coarse polishing on the coarse polishing plate 2 to remove larger surface imperfections and rough areas, before sliding onto the fine polishing plate 3 for fine polishing, further improving the smoothness and reflectivity of the glass bead surface. This achieves a multi-stage polishing function within a single device. The coarse polishing plate 2 is designed in a conical shape. After the inner baffle 4 rises, the coarse polishing plate 2 utilizes its inclined surface to allow the glass beads to slide naturally and smoothly onto the fine polishing plate 3 without the need for additional power or complex guiding devices. This ensures a smooth transition between different polishing stages. This invention enables multi-stage polishing of glass beads with a single device, eliminating the need for additional equipment for enterprises. Investing more funds in purchasing specialized equipment for rough and fine polishing significantly reduces equipment purchase costs for businesses, especially smaller companies with limited funds. This allows them to save substantial funds for other production processes or business expansion. Since multiple machines are not needed to polish glass beads, the device effectively reduces the space required for production. It enables simultaneous rough and fine polishing without requiring operators to transfer glass beads from one machine to another, greatly shortening the production cycle and reducing wasted time in intermediate steps. Operators can achieve continuous polishing production on a single machine, improving production efficiency and meeting the market's high demand for reflective glass beads for highway tunnels.

[0024] like Figures 1 to 6 and Figure 8 As shown, the lifting assembly includes a gantry frame 6 located above the inner baffle 4. An automatic telescopic rod 7 is fixedly installed on the horizontal section of the gantry frame 6. An upper bracket 8 is fixedly installed on the output shaft of the automatic telescopic rod 7. Lower brackets 9 are fixedly installed at both ends of the upper bracket 8. Connecting blocks A10 are fixedly installed at one end of each of the two lower brackets 9. The inner walls of both connecting blocks A10 are fixedly connected to the outer wall of the inner baffle 4. When it is necessary to transfer the coarsely polished glass beads to the fine polishing area, the automatic telescopic rod 7 is activated. The upper support 8 is pulled upwards during the retraction process. As the upper support 8 moves upwards, it will drive the lower support 9 to move upwards as well. When the lower support 9 moves upwards, it will drive the inner baffle 4 to move upwards through the connecting block A10. After the inner baffle 4 moves upwards, it will release the restriction on the glass beads inside it. The glass beads that have completed the coarse polishing will slide down the inclined surface of the coarse polishing plate 2 to the top of the fine polishing plate 3. Then the automatic telescopic rod 7 will descend, causing the inner baffle 4 to move downwards, thereby separating the coarse polishing area from the fine polishing area again, providing conditions for the subsequent simultaneous coarse polishing and fine polishing.

[0025] like Figures 3 to 4 , Figures 6 to 7 and Figure 9As shown, a chip removal groove 11 is provided on the top of the polishing disc 1, and an annular filter plate 12 is fixedly installed on the inner wall of the chip removal groove 11. A chip removal hopper A13 is provided below the polishing disc 1, and an extension plate 14 is fixedly installed at the bottom of the polishing disc 1. The extension plate 14 is located inside the chip removal hopper A13. A baffle assembly A is provided above the polishing disc 1. An annular filter plate 12 is provided between the coarse polishing area and the fine polishing area. After the glass beads have completed coarse polishing, the automatic telescopic rod 7 retracts, causing the inner baffle 4 to move upward. Before the glass beads slide down to the top of the fine polishing plate 3, they will be blocked by the baffle assembly A. When the glass beads are distributed above the annular filter plate 12, the rotating assembly is activated, causing the polishing disc 1 to rotate. As the polishing disc 1 rotates, it moves the glass beads. During this movement, the debris generated during coarse polishing passes through the annular filter plate 12 and is discharged through the chip discharge groove 11, thus achieving automatic debris handling and preventing debris from affecting subsequent fine polishing. The debris discharged through the chip discharge groove 11 is then concentrated and discharged by the chip discharge hopper A13. The extension plate 14 is designed to prevent debris from passing through the polishing disc 1 and... The glass beads are ejected through the gap between the chip removal hoppers A13. In summary, the present invention sets an annular filter plate 12 between the coarse polishing area and the fine polishing area, which can accurately separate the glass beads from the coarse polishing debris. When the glass beads have completed coarse polishing and are distributed above the annular filter plate 12 under the obstruction of the inner baffle 4 and the material blocking component A, the polishing disc 1 rotates and drives the glass beads to move. At this time, the fine debris generated by coarse polishing can pass through the annular filter plate 12, while the glass beads are effectively blocked above the filter plate, ensuring the complete separation of debris and glass beads. This provides a clean environment for subsequent fine polishing. Through effective chip removal and material blocking design, the debris generated during coarse polishing can be completely removed, preventing these debris from adhering to the surface of the glass beads in the fine polishing stage and affecting the fine polishing effect. The clean working environment allows the fine polishing plate 3 to better polish the glass beads, thereby significantly improving the surface smoothness and reflective performance of the glass beads, meeting the high-quality requirements of reflective glass beads for highway tunnels. The automated chip removal process reduces manual intervention, and operators do not need to frequently clean debris or adjust the position of the glass beads, saving a lot of time and energy.

[0026] like Figures 5 to 8As shown, the baffle assembly A includes two slide rods 15, each slidably mounted on the inner wall of the lower support 9. A limiting plate 16 is fixedly mounted on one end of each slide rod 15, and the limiting plates 16 are in contact with the upper support 8. A connecting block B17 is fixedly mounted on the other end of each slide rod 15. A middle baffle 18 is fixedly mounted between the inner walls of the two connecting blocks B17. The middle baffle 18 overlaps the top of the polishing disc 1, and the annular filter plate 12 is located between the middle baffle 18 and the inner baffle 4. When the telescopic rod 7 retracts, causing the lower support 9 to initially move upward, the lower support 9 will not move upward because the slide rod 15 is slidably connected to the lower support 9. The lower support 9 moves upward until it is in contact with the limiting plate 16, at which point the inner baffle 4 releases its restriction on the glass beads. At this time, the middle baffle 18 restricts the glass beads, causing them to distribute in the chip removal area. When the polishing disc 1 rotates, the debris generated by the coarse polishing will pass through the annular filter plate 12 and be discharged. After the chip removal is completed, the automatic telescopic rod 7 continues to retract, causing... As the lower support 9 continues to move upward, it drives the slide bar 15 upward via the limiting plate 16. The slide bar 15 then drives the middle baffle 18 upward via the connecting block B17, thereby releasing the restriction on the glass beads and allowing the cleaned glass beads to enter the polishing plate 3 for polishing. In summary, the material blocking component A achieves a staged and precise material blocking function. When the automatic telescopic rod 7 retracts and the lower support 9 initially moves upward, the middle baffle 18 first restricts the glass beads, keeping them in the chip removal area for chip discharge. During this stage, the middle baffle 18 effectively prevents the glass beads from prematurely sliding down to the polishing plate 3, providing conditions for chip removal. After chip removal is completed, the automatic telescopic rod 7 continues to retract, and the lower support 9 drives the middle baffle 18 upward via the limiting plate 16, releasing the restriction on the glass beads and allowing the cleaned glass beads to smoothly enter the polishing area for polishing. This staged material blocking control method ensures the accurate transition of the glass beads at different polishing stages, improving the precision and quality of the polishing process.

[0027] like Figures 3 to 4 and Figure 6 As shown, the rotating assembly includes a rotating base 19, the inner wall of which is rotatably connected to the outer wall of the turntable 5. A drive motor 20 is fixedly installed at the bottom of the rotating base 19, and the output shaft of the drive motor 20 passes through the rotating base 19 and is fixedly connected to the turntable 5. Several columns 21 are evenly fixedly installed at the bottom of the rotating base 19, and the ends of the columns 21 away from the rotating base 19 are fixedly connected to the inner wall of the chip hopper A13. The rotating base 19 is connected to the chip hopper A13 through the columns 21, providing stable and reliable support for the entire rotating assembly. When polishing is performed, the drive motor 20 is started, and the drive motor 20 drives the turntable 5 to rotate. When the turntable 5 rotates, it drives the polishing disc 1 to rotate, thereby providing power for the polishing work.

[0028] like Figures 1 to 4 and Figure 6As shown, the cross-section of the polishing plate 3 is recessed. A collection box 22 is fixedly installed on the outer wall of the chip hopper A13. The collection box 22 is located outside the polishing disc 1, and its bottom is inclined. A baffle assembly B is provided on the outer side of the polishing disc 1. During polishing, the baffle assembly B restricts the glass beads being polished, ensuring that the glass beads are positioned above the polishing plate 3 for polishing, preventing them from being thrown out. After polishing, when the automatic telescopic rod 7 retracts and the inner baffle 4 moves upward, the baffle assembly B moves upward along with the inner baffle 4, thereby releasing the baffle assembly from the polished glass beads. Due to the concave cross-section of the fine polishing plate 3, the finely polished glass beads remain inside the plate. When the polishing disc 1 rotates to clean the coarsely polished glass beads, the finely polished glass beads are thrown out by centrifugal force, thus achieving automatic feeding. The thrown-out glass beads enter the collection box 22 and are discharged by the inclined surface at its bottom. After the coarsely polished glass beads have finished cleaning, the middle baffle 18 moves upward, causing the glass beads to slide towards the fine polishing plate 3. Because the cross-section of the fine polishing plate 3 is concave, the glass beads remain inside the plate, preventing them from overflowing and being discharged. As described above, when the polishing work is completed, the automatic telescopic rod 7 retracts, causing the inner baffle 4 to move upward. The material-blocking component B then releases the restriction on the finely polished glass beads. While the polishing disc 1 rotates to clean the coarsely polished glass beads, the finely polished glass beads are flung out under centrifugal force. This automatic feeding method requires no manual intervention, greatly improving production efficiency and reducing errors and labor intensity caused by manual operation. When the middle baffle 18 moves upward, allowing the coarsely polished and cleaned glass beads to slide towards the fine polishing plate 3, the concave section of the fine polishing plate 3 plays a crucial role. It effectively prevents the glass beads from overflowing the fine polishing plate 3, avoiding damage from the coarsely polished glass beads. The mixing of the polished glass beads with the finely polished glass beads is crucial for ensuring the quality of the final product. This ensures that each batch of glass beads is precisely polished according to the established process flow, improving the product qualification rate and stability. The fine polishing plate 3, the collection box 22, and the baffle assembly B work together to form a smooth and continuous process flow. From the fine polishing and positioning of the glass beads to the automatic unloading and collection after fine polishing, and then to preventing the mixing of coarse and finely polished glass beads, each link is closely connected without the need for frequent manual intervention and adjustment. This continuous process flow greatly improves production efficiency, shortens the production cycle, and reduces production costs.

[0029] like Figures 2 to 3 , Figures 5 to 6 and Figure 8As shown, the material blocking assembly B includes connecting blocks C23. There are two connecting blocks C23, which are fixedly installed on the ends of the two lower supports 9 away from the connecting block A10. An outer baffle 24 is fixedly installed between the inner walls of the two connecting blocks C23. The inner wall of the outer baffle 24 is slidably connected to the outer wall of the polishing disc 1. During polishing, the outer baffle 24 is fitted on the outside of the polishing disc 1 to block the glass beads and prevent them from being thrown out of the device by the high-speed rotation of the polishing disc 1, thus providing a relatively closed polishing space for the glass beads. The outer baffle 24 is connected to the lower support 9 through the connecting blocks C23. When the lower support 9 moves up and down, causing the inner baffle 4 to move, the outer baffle 24 will move synchronously with the inner baffle 4, providing conditions for automatic material discharge.

[0030] like Figures 1 to 2 and Figure 10 As shown, a guide box 25 is fixedly installed on one side of the collection box 22. A square filter plate 26 is fixedly installed on the inner wall of the guide box 25. A chip discharge hopper B27 is fixedly installed at the bottom of the guide box 25, and the chip discharge hopper B27 is located below the square filter plate 26. The bottom of the collection box 22 is inclined. The glass beads entering the collection box 22 will enter the guide box 25 under the guidance of their own gravity on the inclined surface, thereby realizing the discharge of the glass beads. When the glass beads move in the guide box 25, they will pass over the square filter plate 26. The square filter plate 26 will allow the debris generated by fine polishing to pass through and be discharged. However, due to their large size, the glass beads cannot pass through the square filter plate 26, thereby achieving effective separation of the glass beads and debris, and achieving the purpose of cleaning the glass beads after fine polishing. After the debris passes through the square filter plate 26, it will be discharged through the chip discharge hopper B27.

[0031] like Figure 1 As shown, a base 28 is provided below the chip hopper A13, and several support legs 29 are fixedly installed on the top of the base 28. The ends of the support legs 29 away from the base 28 are all fixedly connected to the chip hopper A13. The chip hopper A13 is connected to the base 28 through the support legs 29, so that the chip hopper A13 and the base 28 are connected into a whole, which enhances the overall integrity of the device, makes the whole device more stable during operation, effectively reduces shaking, avoids the impact of device instability on the grinding and polishing accuracy, and ensures the processing quality of glass beads.

[0032] like Figures 1 to 2 and Figures 10 to 11As shown, a quality inspection device for rapid grinding and polishing of reflective glass beads for highway tunnels includes two fixed frames 30, which are fixedly installed on the top of a base 28. A test tank 31 is fixedly installed between the fixed frames 30. A discharge box 32 is fixedly installed at one end of the test tank 31, and a feed box 33 is fixedly installed at the other end of the test tank 31. The feed box 33 is connected to a guide box 25. The two fixed frames 30 fix the test tank 31, providing a solid and reliable support for the test tank 31. After the glass beads enter the guide box 25, they will enter the test tank 31 through the feed box 33. The test tank 31 will inspect key quality indicators such as particle size, roundness, and surface smoothness of the glass beads. After the inspection is completed, the glass beads will be discharged through the discharge box 32.

The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
