Description

Technical Field

[0001] This invention relates to the field of stone processing equipment technology, and in particular to an intelligent automatic grinding machine for stone processing. Background Technology

[0002] Existing intelligent automatic grinding machines for stone processing are specialized equipment for stone surface grinding and polishing processes. They are widely used in building decoration, stone product processing, and other fields. The core of the machine consists of a frame, grinding system, positioning and clamping device, intelligent control system, and auxiliary components. The frame is a heavy-duty steel structure that provides stable support. The grinding system includes multiple grinding heads that are driven by motors to rotate at high speed. The grinding heads can be equipped with abrasives of different grit sizes to adapt to different processes such as rough grinding, fine grinding, and polishing. The positioning and clamping device mostly uses hydraulic or pneumatic clamps to securely fix the stone. Some machines support simultaneous processing at multiple stations. The intelligent control system is based on a PLC and combined with touch screens, sensors, etc. It can preset processing parameters to achieve automated continuous processing. Some high-end machines integrate visual recognition technology to preliminarily detect the size of the stone. Auxiliary components include cooling systems, dust removal devices, safety guardrails, emergency stop switches, and other safety components. Although the overall equipment improves the degree of automation, it has limitations such as poor adaptability to irregularly shaped stones, difficulty in balancing accuracy and efficiency, high grinding head maintenance costs, and insufficient real-time monitoring of stone conditions.

[0003] Existing intelligent automatic grinding machines for stone processing mostly employ fixed table or linear conveyor structures for their processing stations. The grinding mechanism typically can only translate along a preset axis or make limited angular adjustments with a single rotating axis. The overall processing trajectory is standardized linear or planar. For irregularly shaped stones, such as curved countertops, wavy decorative panels, and three-dimensional carved stone, the grinding heads at fixed stations struggle to conform to complex contours due to irregular curved surfaces, protrusions, or depressions. When processing the edges of curved stones, traditional grinding machines can only perform linear grinding, requiring multiple manual adjustments to the stone's placement angle. This not only results in uneven edges or curvature but also easily leads to sharp corners and uneven curvature. Grinding marks are produced; for stones with three-dimensional carvings, the grinding head cannot penetrate deep into the carving gaps or recessed areas, easily resulting in missed grinding or over-grinding, which damages the integrity of the carving details. In addition, some irregularly shaped stones require multi-angle bevel grinding, but the angle adjustment range of existing grinding machines is limited, making it impossible to accurately match the bevel angle. This results in a large deviation between the processed stone and the design drawings, requiring additional manual correction, which increases processing costs and reduces production efficiency. It is difficult to meet the diverse processing needs of irregularly shaped stones and has certain adverse effects on people's use. In order to solve the shortcomings of existing technology, we propose an intelligent automatic grinding machine for stone processing. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, efficient and precise processing of flat and irregularly shaped stone is achieved through multi-structure collaboration. For flat stone, the first servo motor drives the rotating block and sliding rod in linkage, and with the guidance of the limit frame and horizontal sliding sleeve, the horizontal grinding head moves smoothly back and forth, ensuring the flatness of the surface grinding. For irregularly shaped or textured stone, the second servo motor drives the movable grinding head to deflect through bevel gear transmission, and the third servo motor drives the threaded rod and connecting rod in linkage to further optimize the grinding trajectory and adapt to the processing of irregular edges and corners. The design of buffer spring and lifting ring ensures transmission stability and avoids vibration affecting accuracy. This design solves the problem of poor adaptability of traditional equipment to irregularly shaped stone, realizes multi-scenario processing of single equipment, and improves processing flexibility and finished product accuracy.

[0015] 2. In this invention, wastewater and debris are collected in the inner collection tank and then guided to the collection screen frame by the inclined surface of the upper clamp. The fourth servo motor drives the deflection centrifugal block to vibrate the screen frame. Combined with multiple sets of buffer springs, the screening effect is enhanced, effectively separating solids and liquids. The filtered wastewater is diverted to the grinding head through a water pump, multiple sets of water pipes and three-way flexible hoses for cooling and rinsing. The entire process does not require additional water supply, greatly reducing water consumption and wastewater discharge and treatment costs. The buffer structure ensures the stability of the screening and circulation process, avoids equipment failure, and further improves the economy and environmental protection of the processing.

[0016] 3. In this invention, a fifth servo motor drives a synchronous wheel transmission, which in turn drives the deflection frame to flip through the deflection block and connecting rod linkage. The second electric telescopic rod controls the anti-slip clamp to clamp the stone, ensuring a stable flipping process. At the same time, the synchronous wheel, in conjunction with the rotating column and connecting rod, pushes the third deflection block to slide, driving the push plate to reset the flipped stone to the transport device. The Y-shaped movable groove and baffle design ensure precise sliding stroke, and the two sets of mirror structures ensure uniform force distribution. This design eliminates the need for manual intervention in the flipping process, solving the cumbersome problem of manual handling and flipping required in traditional double-sided processing, shortening the processing interval, ensuring production continuity, and improving batch processing efficiency.

[0019] 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.

[0020] Example 1, as Figures 1-6 As shown, when grinding a flat stone surface, the first servo motor 21 is first started, driving the detachably connected first rotating block 22 to rotate. The rotation of the first rotating block 22 then drives the sliding rod 23, causing the linked second rotating block 25 to move, thus sliding the second rotating block 25 against the outer wall of the first fixed rod 26. Simultaneously, as the second rotating block 25 slides against the outer wall of the first fixed rod 26, it pushes the first fixed rod 26 to slide against the outer wall of the second fixed rod 212. Because... The second fixed rod 212 limits the first fixed rod 26, thereby causing the first fixed rod 26 to reciprocate horizontally, which in turn pushes the first electric telescopic rod 27 and the horizontal grinding head 28 to adjust their positions. The limiting frame 29 at the junction of the first electric telescopic rod 27 and the first fixed rod 26 slides along the limiting groove 210 of the device housing 1 to ensure smooth movement. The horizontal sliding sleeve 211 at the other end of the first fixed rod 26 slides along the second fixed rod 212, and works with the positioning frame 213 to achieve fine adjustment of the lateral position of the horizontal grinding head 28, thus completing the grinding of the stone surface. When grinding irregularly shaped or textured stone is required, the second servo motor 214 on one side of the positioning frame 213 is activated. The second servo motor 214 drives the first bevel gear 222 to mesh with the second bevel gear 223 and rotate. The second telescopic frame 224 at the axis of the second bevel gear 223 pushes the fourth bevel gear 228 to mesh with the third bevel gear 227, causing the movable grinding head 229 to deflect slightly. At the same time, the third servo motors 215 on both sides of the positioning frame 213 drive the threaded rod 218 to rotate, causing the threaded sleeve 216 to move. Through the swing block 217, the first connecting rod 219 is linked, pushing the second connecting rod 226 to adjust the angle, further adjusting the deflection trajectory of the movable grinding head 229 to adapt to the grinding of irregularly shaped stone or textured edges and corners. The lifting ring 221 on one side of the first telescopic frame 220 contacts the outer wall of the second telescopic frame 224 to ensure transmission stability.

[0021] Example 2, as Figures 7-13 As shown, the wastewater and debris generated during grinding fall into the collection tank 31 on the lower side of the device housing 1. The inclined surface of the upper bracket 32 ​​guides the wastewater to the collection screen frame 310. The fourth servo motor 36 is started and installed in the middle of the third movable block 35. The third movable block 35 slides along the first movable groove 34 of the upper bracket 32. The second buffer springs 37 on both sides provide buffering, driving the deflection centrifugal block 38 to rotate, causing the collection screen frame 310 to vibrate. The screening effect is enhanced by the third buffer springs 311 around the perimeter, separating the wastewater and debris. The second movable block 312 is slidably installed in the second movable groove 313 of the lower bracket 33. The fourth buffer springs 320 on both sides ensure the stability of the collection screen frame 310 when it vibrates. The water pump 314 on the first horizontal plate 321 is started, and the filtered wastewater is collected through the water collection port of the third water pipe 318. The wastewater is then transported to the water pump 314 through the second water pipe 317, and then diverted to the horizontal grinding head 28 and the movable grinding head 229 through the first water pipe 315 and the three-way flexible hose 316 to achieve the purpose of circulating water for cooling and rinsing, thus saving water.

[0022] Example 3, as Figures 13-15As shown, when some stone needs to be polished on both sides, the fifth servo motor 42 inside the protective shell 41 is activated. The fifth servo motor 42 drives the first synchronous pulley 43 to rotate, which in turn drives the second synchronous pulley 411 to rotate via a synchronous belt. The first deflection block 44 at the axis of the first synchronous pulley 43 drives the third connecting rod 45 to drive the second deflection block 46, pushing the first rotating column 47 and the deflection frame 48 to flip. The second electric telescopic rod 49 on the deflection frame 48 extends and clamps the stone through the anti-slip clamp 410, completing the flipping action. The second synchronous pulley... The second rotating column 412 at the axis 411 drives the fourth connecting rod 414 to link the linkage rod 417, pushing the third deflecting block 416 to slide along the third movable groove 415 of the second fixed block 413. The baffle on the upper side of the third deflecting block 416 limits the sliding stroke. The two sets of third deflecting blocks 416 move synchronously through the linkage rod 417, driving the second horizontal plate 418 and the third electric telescopic rod 419 to adjust their positions. The push plate 420 of the third electric telescopic rod 419 pushes the stone back to the transport device, realizing the automated connection of double-sided processing. The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
