[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] Combination Figures 1-6A roller conveyor stone cutting production line includes a first frame 1, with a central control panel mounted on the side wall of the first frame 1. The central control panel is electrically connected to various electrical control components in the production line. Gantry frames 2 are respectively mounted on both sides of the top of the first frame 1. A three-dimensional moving cutting mechanism 3 is installed between the two gantry frames 2, which can move flexibly in three dimensions to perform cutting operations. Two second frames 4 are fixedly connected to both sides of the first frame 1. A first roller conveyor 5 is mounted on the top of each of the two second frames 4. A drive motor is installed in each second frame 4. The first roller conveyors 5 are connected to the drive motors via chain transmission assemblies. The drive motors drive the first roller conveyors 5 through the chain transmission assemblies. One roller conveyor 5 rotates, thereby conveying the stone from one side of the production line to a position close to the first frame 1. One of the second frames 4 is equipped with a feeding mechanism 6 on its exterior. The feeding mechanism 6 transports the stone onto the first roller conveyor 5. A conveying mechanism 7 is set at the top of the first frame 1 between two gantry frames 2. A support component 8 is set inside the conveying mechanism 7. A guide and positioning component 9 is set between the support component 8 and the conveying mechanism 7. The conveying mechanism 7 further conveys the stone to the cutting area. The support component 8 provides stable support when the stone is cut, and the guide and positioning component 9 ensures that the stone maintains a precise position during the cutting process. The three work together to ensure the accuracy and stability of the stone cutting.

[0025] Furthermore, the conveying mechanism 7 includes a mounting frame 71, with a second roller conveyor 72 mounted on the top of the mounting frame 71. A drive motor is installed in the mounting frame 71, and the second roller conveyor 72 is connected to the drive motor via a chain transmission assembly. It is used to receive the stone conveyed by the first roller conveyor 5 and continue to convey it to the cutting station. Multiple linear bearings 73 are mounted in a rectangular array at the bottom of the mounting frame 71. Each linear bearing 73 has a guide column 74 slidably connected inside it. The bottom end of each guide column 74 is fixedly connected to the top of the first frame 1. A lifting assembly 75 for lifting the mounting frame 71 is provided between the first frame 1 and the mounting frame 71. The lifting assembly 75 can control the lifting of the mounting frame 71 according to the stone cutting requirements, so that the second roller conveyor 72 cooperates with the wooden blocks 83 in the support assembly 8 to realize the switching of the stone support state. The linear bearings 73 and the guide columns 74 cooperate with each other to provide precise guidance for the lifting of the mounting frame 71, ensuring that its lifting process is stable and reliable.

[0026] Furthermore, the lifting assembly 75 includes two connecting rods 751, which are located on the outer sides of two opposite side walls of the mounting frame 71. Each connecting rod 751 has a crank arm 752 hinged to both ends. A rotating shaft 753 is fixedly connected between every two corresponding crank arms 752 on both sides of the mounting frame 71. Two seated bearings 754 are rotatably connected to the surface of each rotating shaft 753. The two seated bearings 754 are fixedly connected to both sides of the top of the first frame 1. A support shaft 755 is fixedly connected to the end of each crank arm 752 away from the connecting rod 751. A support bearing 756 is fixedly connected to the surface of the support shaft 755. A support plate 757 is fixedly installed above the support bearing 756 at the bottom of the mounting frame 71. A hydraulic cylinder 758 is hinged to one end of one of the connecting rods 751. The hydraulic cylinder is hinged to the side wall of the mounting frame. When the mounting frame 71 needs to be lifted, the hydraulic cylinder 758 extends, pushing the connecting rod 751 to move. The connecting rod 751 drives the hinged... The crank arm 752 rotates around the rotating shaft 753. When the crank arm 752 rotates, it drives the support shaft 755 and the support bearing 756 to move upward and towards the cylinder until the support bearing 756 contacts the support plate 757 at the bottom of the mounting frame 71. Due to the guiding effect of the guide column 74 and the linear bearing 73, the support bearing 756 slides on the surface of the support plate 757, which in turn drives the support plate 757 and the mounting frame 71 to move upward, thereby raising the mounting frame 71 and the second roller conveyor 72 at its top. When it is necessary to lower the mounting frame 71, the cylinder 758 retracts, pulling the connecting rod 751, causing the crank arm 752 to rotate in the opposite direction. The support shaft 755 and the support bearing 756 move downward and away from the cylinder. Under its own weight and driven by the crank arm 752, the mounting frame 71 slides down along the guide column 74 through the linear bearing 73. The second roller conveyor 72 then descends until the stone falls onto the wooden block 83 of the support assembly 8, completing the descent of the mounting frame 71.

[0027] Furthermore, the support assembly 8 includes a support frame 81 fixedly connected to the top of the first frame 1. Multiple support frames 82 are fixedly connected to the top of the support frame 81, and the multiple support frames 82 are evenly distributed in the gap between each pair of adjacent rollers in the second roller conveyor 72. A wooden block 83 is provided on the top of each support frame 82. When the mounting frame 71 is lowered, the second roller conveyor 72 falls between the support frames 82, and the wooden block 83 provided on the top of the support frame 82 can effectively support the stone.

[0028] Furthermore, the guide positioning component 9 includes multiple double-rod cylinders 91 fixedly connected to one side of the top of the mounting frame 71. A push plate 92 is installed at the output end of the double-rod cylinder 91. The double-rod cylinder 91 drives the push plate 92 to move through the telescopic action, thereby guiding and positioning the stone laterally and ensuring the accurate position of the stone in the horizontal direction. Multiple corner pressing cylinders 93 are installed on the side of the support frame 81 near the double-rod cylinders 91. The multiple corner pressing cylinders 93 and the multiple double-rod cylinders 91 are alternately distributed in the gap between every two adjacent rollers in the second roller conveyor 72. When the stone falls onto the wooden block 83 of the support component 8, the corner pressing cylinder 93 starts to press down, fixing the stone longitudinally.

[0029] Furthermore, the feeding mechanism 6 includes a third frame 61 that partially covers the second frame 4. A first sliding frame 62 is slidably connected to the crossbeam of the third frame 61 in the horizontal direction. The first sliding frame 62 is driven to slide by a motor gear and rack module. A second sliding frame 63 is slidably connected to the inside of the first sliding frame 62 in the vertical direction. The second sliding frame 63 is also driven to slide by a motor gear and rack module. A suction cup feeding rack 64 is installed at the bottom of the second sliding frame 63. The first sliding frame 62 and the second sliding frame 63 move horizontally and vertically respectively through the drive of the motor gear and rack module. The two work together to precisely control the position of the suction cup feeding rack 64. The suction cup feeding rack 64 grabs the stone through suction and, driven by the first sliding frame 62 and the second sliding frame 63, accurately transports the stone onto the first roller conveyor 5, realizing the automated operation of stone feeding.

[0030] Working principle:

[0031] The first sliding frame 62 slides horizontally on the crossbeam via a motor gear and rack module. The second sliding frame 63 slides vertically within the first sliding frame 62, driven by the motor gear and rack module. Through the coordinated movement of the two, the suction cup loading rack 64 moves to the stone storage area. After the suction cup loading rack 64 adsorbs the stone, it transports the stone to the first roller conveyor 5 at the top of the second frame 4 through the reverse movement of the first sliding frame 62 and the second sliding frame 63. The first roller conveyor 5 is connected to the drive motor via a chain transmission assembly, thereby transporting the stone towards the first frame 1.

[0032] The stone is conveyed via the first roller conveyor 5 to the second roller conveyor 72 of the conveying mechanism 7 at the top of the first frame 1. The second roller conveyor 72 is also connected to the drive motor via a chain drive assembly to continue conveying the stone. During the conveying process, the guide and positioning assembly 9 starts to work. The double-rod cylinder 91 on one side of the top of the mounting frame 71 extends and pushes the push plate 92 to guide and position the stone laterally. When the stone is conveyed to the designated position and the lateral guidance and positioning are completed, the hydraulic cylinder 758 in the lifting assembly 75 retracts, pulling the connecting rod 751, which drives the crank arm 752, which is hinged to the connecting rod 751, to rotate around the rotation axis 753. When the crank arm 752 rotates, it drives the support shaft 755 and the support bearing 756 to move downward and away from the hydraulic cylinder. The linear bearing 73 at the bottom of the mounting frame 71 slides smoothly down along the guide column 74. As the mounting frame 71 descends, the second roller conveyor 72 falls into the gap between the wooden blocks 83 at the top of the support frame 82 in the support assembly 8, and the stone falls on the wooden blocks 83. At this point, the corner-down cylinder 93 presses down to fix the stone longitudinally, ensuring that the stone is stable in position during the cutting process.

[0033] After the stone is positioned and fixed, the three-dimensional moving cutting mechanism 3 between the two gantry frames 2 begins to cut the stone. The three-dimensional moving cutting mechanism 3 can move in three dimensions, enabling precise cutting of different parts and shapes of the stone.

[0034] After cutting, the hydraulic cylinder 758 extends, pushing the connecting rod 751, causing multiple crank arms 752 to rotate around the rotating shaft 753. The rotation of the crank arms 752 moves the support shaft 755 and the support bearing 756 upward and towards the hydraulic cylinder until the support bearing 756 contacts the support plate 757 at the bottom of the mounting frame 71. Due to the guiding effect of the guide column 74 and the linear bearing 73, the support bearing 756 slides on the surface of the support plate 757, while driving the support plate 757 and the mounting frame 71 to move upward. After the mounting frame 71 rises and resets, the second roller conveyor 72 lifts the stone again and starts again, transporting the finished stone to the first roller conveyor 5, completing the entire stone cutting process.

[0035] During the overall operation of the equipment, the lens in the vision acquisition component will collect image information of the cutting area in real time. This image data will be transmitted to the central control console 3 in a timely manner. The operator can observe the cutting process in real time through the display screen of the central control console so as to promptly detect potential problems such as cutting deviation and tool wear, and flexibly adjust the equipment parameters or take corresponding measures according to the actual situation to ensure the smooth progress of the cutting work and the stability of the cutting quality.
