DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] like Figures 1 to 9 As shown, the present invention provides a technical solution: a marble slab production device, comprising a workbench 1, a support plate 2 is symmetrically arranged above the workbench 1, a rubber pad 3 is fixedly connected to the top of the support plate 2, a clamping plate 4 is arranged on both sides of the rubber pad 3, the inner wall of the clamping plate 4 is slidably connected with a positioning plate 5, the clamping plate 4 and the positioning plate 5 are connected by a nut, a fixed platform 7 is arranged above the support plate 2, the top of the fixed platform 7 is fixedly connected to a motor 6, the output shaft of the motor 6 is fixedly connected to a grinding wheel 8, driving components for driving the fixed platform 7 to lift and lower are arranged on both sides of the fixed platform 7, hooking components connecting the clamping plate 4 and the fixed platform 7 are arranged on both sides of the fixed platform 7, a flipping component for driving the clamping plate 4 to rotate is arranged on the side of the clamping plate 4, and double pulling components are arranged on both sides of the support plate 2, the double pulling components are used to drive the two support plates 2 to pull apart and tilt each other.

[0033] During operation: In the initial state, the two support plates 2 remain horizontal and merged together, and the rubber pad 3 is also in a horizontal state, providing a stable base for the entire grinding process. The operator carefully places the plate to be ground on the upper surface of the rubber pad 3 to ensure that the plate is centered. Then, the operator slowly twists the nut to make the positioning plate 5 steadily lower until it fits the top surface of the plate, thereby tightening the center position of both sides of the plate to prevent the plate from shifting during the grinding process;

[0034] When performing the grinding work, the fixed platform 7 is first driven to descend steadily by the driving component, and the grinding wheel 8 gradually approaches the upper surface of the stone slab. When the grinding wheel 8 is about to fit the upper surface of the plate, the side surface of the fixed platform 7 will generate a certain pressure on the surfaces of the two clamping plates 4, so that the unground lower surface of the plate is evenly squeezed by the rubber pad 3. The rubber pad 3 is made of highly elastic and wear-resistant material and can undergo adaptive deformation, thereby effectively supporting the unground lower surface of the plate, avoiding the uneven bottom surface affecting the stable placement of the plate and the grinding accuracy. When the grinding wheel 8 fits the surface of the plate, the motor 6 is started to drive the grinding wheel 8 to rotate for grinding. During the grinding process, the operator can observe the grinding effect and adjust the operating parameters of the driving component in time to ensure the grinding quality.

[0035] After the first side of the plate is polished, the driving assembly drives the grinding wheel 8 to rise and reset. When the grinding wheel 8 rises to a certain height (a certain distance must be left between it and the plate to provide space for the plate to rise and turn over), the hooking assembly reliably connects the fixed platform 7 and the clamping plate 4. After the fixed platform 7 continues to rise and move for a distance, it will drive the entire plate to rise through the clamping plate 4. When the plate rises to a certain height (a height that does not affect the smooth turning of the plate), the clamping plate 4 triggers the turning assembly, which drives the plate to turn 180 degrees through the clamping plate 4, so that the other side of the plate that is not polished faces straight up. When the plate falls back above the rubber pad 3, the unpolished side faces up, ready for the polishing work on the other side;

[0036] When the plate is turned over, the debris dropped from the surface of the rubber pad 3 will also fall into the collection groove of the workbench 1.

[0037] Through the above embodiment, after the first surface of the plate is polished, when the polishing wheel 8 rises to a certain height to provide enough space for the plate to rise and flip, the hook connecting assembly reliably connects the fixed table 7 and the clamping plate 4 together, and the connection enables the subsequent rising action of the fixed table 7 to be transmitted to the clamping plate 4, thereby driving the entire plate to rise to a suitable height and trigger the flipping assembly to flip. After one surface of the plate is polished, the plate can be quickly and accurately lifted and flipped, thereby improving the efficiency of the entire marble plate polishing work; the double-pulling assembly tilts the support plate 2 and the rubber pad plate 3 by pulling them apart, so that the debris falls into the collection groove opened in the workbench 1, avoiding the influence of the debris on the placement and polishing accuracy of the plate, ensuring the polishing quality, and timely cleaning of the debris by the double-pulling assembly reduces the wear of the rubber pad plate 3, prolonging the service life of the entire device.

[0038] As shown in Figures 3 and 4 , the driving assembly includes two inner groove slides 10, which are fixedly installed on the top of the workbench 1. The inner walls of the inner groove slides 10 are slidably connected with inner sliding blocks one 11. The fixed table 7 is fixedly connected between one side of the two inner sliding blocks one 11. The upper part of one of the inner groove slides 10 is fixedly installed with a hydraulic cylinder 9. The output shaft of the hydraulic cylinder 9 is fixedly connected with the top of one of the inner sliding blocks one 11.

[0039] When the polishing work is needed, the hydraulic cylinder 9 is started, and the output shaft drives the inner sliding block one 11 to slide downward in the inner wall of the inner groove slide 10. As the fixed table 7 descends, the polishing wheel 8 gradually approaches the upper surface of the marble plate placed on the rubber pad plate 3, until the polishing wheel 8 is about to adhere to the upper surface of the plate. Similarly, after polishing is completed, the output shaft of the hydraulic cylinder 9 is retracted upward, and through the rising of the fixed table 7, the polishing wheel 8 gradually moves away from the upper surface of the plate.

[0040] As shown in Figures 3 to 6 , one side of the two clamping plates 4 is fixedly connected with a rotating connecting rod 14. One end of the rotating connecting rod 14 is rotatably connected with an inner sliding block two 13. The inner sliding block two 13 is slidably connected with the inner wall of the inner groove slide 10 and is adapted to each other. The bottom of the inner sliding block two 13 is fixedly connected with a return spring 28. One end of the return spring 28 is fixedly connected with the inner wall of the inner groove slide 10. The bottom of the inner sliding block one 11 is fixedly connected with a pressing rod 12.

[0041] During operation: when the hydraulic cylinder 9 drives the inner slider 11 to descend along the inner groove slide 10, the lower pressure rod 12 moves downward synchronously with the inner slider 11. During the descending process, the lower pressure rod 12 will gradually approach and finally contact the inner slider 2 13, exerting a downward pressure on the inner slider 2 13. The inner slider 2 13 is affected by this downward pressure, overcomes the elastic force of the reset spring 28, and slides downward along the inner wall of the inner groove slide 10, so that the clamping plate 4 drives the plate to move downward, allowing the uneven bottom surface of the plate to be pressed into the interior of the rubber pad 3. The rubber pad 3 undergoes adaptive deformation to provide effective support for the plate, thereby preventing the uneven bottom surface from affecting the stable placement of the plate and the grinding accuracy.

[0042] like Figures 4 to 6 As shown, the hooking assembly has two L-shaped connecting plates 23, and the two L-shaped connecting plates 23 are respectively fixedly connected to the other side of the inner slider 2 13, and the other side of the inner slider 1 1 is fixedly connected with a side connecting plate 20, and the bottom of the side connecting plate 20 is fixedly connected with a hinge 21, and the shaft of the hinge 21 is fixedly connected with a hook plate 22, and the outer side of the hook plate 22 is in contact with one side of the L-shaped connecting plate 23, and a torsion spring 24 is fixedly connected between the inner side of the hook plate 22 and one side of the hinge 21, and one side of the hinge 21 is fixedly connected with a limiting plate 25, and the inner side of the limiting plate 25 is in contact with the outer wall of the hook plate 22.

[0043] During operation: when the inner slider 11 descends, the hook plate 22 is driven to descend together through the side connecting plate 20. During the descending process of the hook plate 22, a part of its outer side is blocked by the outer side of the L-shaped connecting plate 23. Under the obstruction of the L-shaped connecting plate 23, the hook plate 22 rotates around the shaft of the hinge 21. At this time, the torsion spring 24 is compressed to produce elastic deformation. As the inner slider 11 continues to descend, when the hook plate 22 descends to a certain position and passes the obstruction point of the L-shaped connecting plate 23, the hook plate 22 returns to its original position under the rebound action of the torsion spring 24. After the first side of the plate is polished, the inner slider 11 first drives the grinding wheel 8 to rise to a The top of the hook plate 22 contacts the bottom of the L-shaped connecting plate 23. Due to the restriction of the limit plate 25, the hook plate 22 cannot be hinged and rotated around the hinge 21 and the hinge 21, and then the bottom of the L-shaped connecting plate 23 is lifted and moved upward. The L-shaped connecting plate 23 is connected to the clamping plate 4, and finally the plate is driven to start rising through the clamping plate 4. When the plate rises to a certain height (a height that does not affect the smooth flipping of the plate), the clamping plate 4 triggers the flipping assembly, and the flipping assembly drives the plate to flip 180 degrees through the clamping plate 4.

[0044] like Figures 4 to 6 As shown, one end of the shaft of the hinge 21 is fixedly connected to a gear 2 26 , and one side of the inner groove slide 10 is fixedly connected to a rack plate 27 , and the teeth of the gear 2 26 can mesh with the teeth of the rack plate 27 .

[0045] During operation: when the hook plate 22 hooks the bottom of the L-shaped connecting plate 23 and rises until the plate is completely flipped, and continues to rise, the teeth of gear 26 can mesh with the teeth of rack plate 27. Under the action of the meshing of gear 26 and rack plate 27, the shaft of the hinge 21 is forced to rotate, thereby causing the hook plate 22 to rotate around the shaft of the hinge 21, and the hook plate 22 will gradually disengage from the hooking state with the L-shaped connecting plate 23. When the hook plate 22 is completely disengaged from the L-shaped connecting plate 23, the subsequent rising action of the inner slider 11 will no longer drive the clamping plate 4 and the plate to continue to rise. The inner slider 2 13 will drive the clamping plate 4 and the plate to reset under the elastic force of the reset spring 28, waiting for the next hooking operation.

[0046] like Figures 4 and 5 As shown, the flip assembly includes two gears 15, which are fixedly connected to the outer wall of the rotating connecting rod 14 respectively. A rack plate 16 is provided on one side above the gear 15. The teeth of the gear 15 can engage with the teeth of the rack plate 16. The number of teeth of the rack plate 16 is half the number of teeth of the gear 15.

[0047] During operation: when the inner slider 11 drives the clamping plate 4 and the plate to rise, the inner slider 2 13 drives the clamping plate 4 to rise through the rotating connecting rod 14, and the gear 15 fixed on the outer wall of the rotating connecting rod 14 rises accordingly. As the rising height increases, the gear 15 gradually approaches the rack plate 16 until the teeth of the gear 15 begin to mesh with the teeth of the rack plate 16, causing the gear 15 to rotate and flip through the rotating connecting rod 14 and the clamping plate 4, thereby driving the clamped plate to flip. Since the number of teeth on the rack plate 16 is half of the number of teeth on the gear 15, the clamping plate 4 drives the plate to flip 180 degrees, thereby realizing the flipping of both sides of the plate.

[0048] like Figures 4 and 5 As shown, the bottom of the rack plate 16 is fixedly connected to a moving block 17, the top of the workbench 1 is symmetrically fixedly connected to a connecting platform 19, and the top of the connecting platform 19 is fixedly connected to a telescopic rod 18, one end of the telescopic rod 18 is fixedly connected to one side of the moving block 17, and the moving block 17 and the connecting platform 19 are slidably connected.

[0049] During operation: after the plate rises and flips over, the telescopic rod 18 drives the moving block 17 to move along the surface of the connecting platform 19, so that the rack plate 16 moves sideways. When the gear 15 descends, its teeth do not mesh with the teeth of the rack plate 16, ensuring that the flipping assembly drives the plate to flip smoothly and does not flip back when it descends and resets, resulting in the first side still facing up when it falls onto the rubber pad 3.

[0050] like Figures 7 to 9As shown, the double-pull assembly includes two bearing seats 29, the inner walls of the bearing seats 29 are rotatably connected to the torsion spring shaft 30, the outer wall of the torsion spring shaft 30 is fixedly connected to the inner wall of one end of the support plate 2, and both sides of the bearing seats 29 are fixedly connected to the extrusion blocks 32, and both sides of the inner slider 13 are fixedly connected to the extrusion rod 31, and the extrusion block 32 and the extrusion rod 31 fit together.

[0051] During operation: When the inner slider 2 13 drives the plate to rise, it will drive the extrusion rod 31 to rise synchronously. During the rising process, the inclined surface of the extrusion rod 31 will gradually contact the extrusion block 32 and produce an extrusion effect. Under the continuous extrusion of the inclined surface of the extrusion rod 31, the extrusion block 32 will be subjected to a horizontal thrust, and the thrust will be transmitted to the bearing seat 29, causing the two bearing seats 29 to move to both sides of the workbench 1. Therefore, the two support plates 2 and the rubber pad 3 will be pulled apart from each other, and the distance between the two support plates 2 and the rubber pad 3 will gradually increase, preparing for subsequent tilting.

[0052] like Figures 7 to 9 As shown, the outer walls of both ends of the torsion spring shaft 30 are fixedly connected with a balance rod 35, the bottom of one end of the balance rod 35 is fixedly connected with a hinge seat 36, the inner wall of the hinge seat 36 is hinged with a counterweight block 37, and the top of the workbench 1 is fixedly connected with a plurality of inclined inner groove seats 38, and the counterweight block 37 is slidably connected to the inclined inner groove seat 38.

[0053] During operation: When the two support plates 2 are gradually unfolded and separated by the double-pull assembly, the balance bar 35 fixedly connected to the outer walls of both ends of the torsion spring shaft 30 will change position as the support plates 2 are unfolded. Since the counterweight block 37 is connected to the bottom of one end of the balance bar 35 through the hinge seat 36, and the counterweight block 37 is slidably connected to the multiple inclined inner groove seats 38 fixed on the top of the workbench 1, during the unfolding process of the support plates 2, the counterweight block 37 will move along the inner wall inclined surface of the inclined inner groove seat 38. The inclined surface design of the inclined inner groove seat 38 causes the counterweight block 37 to be subjected to a downward component force when moving, and this component force will be passed through The hinge seat 36 forcibly pulls one end of the balance bar 35 to rotate downward. When the hinge seat 36 rotates downward with one end of the balance bar 35, it will generate a torque on the torsion spring shaft 30, thereby driving the torsion spring shaft 30 to rotate. Because the outer wall of the torsion spring shaft 30 is fixedly connected to the inner wall of one end of the support plate 2, the rotation of the torsion spring shaft 30 will drive the support plate 2 to rotate around the center point of the torsion spring shaft 30 as the axis, eventually causing the surface of the support plate 2 to gradually tilt. At the same time, in order to facilitate the re-merging of the two bearing seats 29, the balance bar 35 drives the surface of the support plate 2 to restore to a flat state when merging.

[0054] like Figure 7 and Figure 9As shown, a receiving plate 33 is fixedly connected to both sides of the workbench 1, a sliding connection is formed between the bearing seat 29 and the inner wall of the receiving plate 33, an elastic rod 34 is fixedly connected between the bottom of the bearing seat 29 and the inner wall surface of the receiving plate 33, and a micro-vibrator 39 is provided at the bottom of the support plate 2.

[0055] During operation: when the inner slider 13 drives the flipped plate to descend and reset, under the action of the elastic rod 34, the two bearing seats 29 return to their original positions, the two support plates 2 are reunited and their surfaces remain flat. Through the provided micro-vibrator 39, after the two support plates 2 are tilted, their surfaces can vibrate, so that the debris can fall into the collection trough better.

[0056] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.
