[0002] Marble is a high-quality building material, commonly used for flooring, walls, countertops, and more. Marble processing typically involves cutting, polishing, and carving to create finished products that meet design requirements. Marble slabs are a common substrate for marble processing. Marble processing involves many steps, often requiring the slabs to be flipped between adjacent steps to process the back side.

[0003] Existing methods for flipping marble slabs mostly involve using clamping and flipping equipment and suction cup robotic arms. Suction cup robotic arms can only flip lighter marble slabs, while clamping and flipping equipment can flip heavier marble slabs. However, these equipment are relatively expensive and cannot continuously flip the slabs, resulting in low work efficiency. Utility Model Content

[0021] 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.

[0022] Please see Figures 1-5 In this embodiment of the present invention, a marble processing flipping device includes two horizontally symmetrically placed conveyors 1. Each conveyor 1 includes multiple conveying units 11, which are arranged in parallel and equidistant. The driving ends of the multiple conveying units 11 are connected in series on a drive shaft 12 to drive the multiple conveying units 11 to work simultaneously. One end of the drive shaft 12 is connected to the driving end of a first motor 13 through a coupling.

[0023] A tilting mechanism 2 is provided between two conveyors 1. The tilting mechanism 2 includes a support 201 with an "H"-shaped structure. A rotating drum 202 is provided on the inner side of the upper end of the support 201. The rotating drum 202 is a cylindrical structure with one end closed. A shaft column 207 is integrally formed in the middle of the closed end of the rotating drum 202. The shaft column 207 is rotatably connected to one end of the support 201 through a bearing. Four first through slots 203 are provided on the outer wall of the rotating drum 202 at equal intervals. Four sets of tilting blade assemblies are also distributed on the outer wall of the rotating drum 202. Each set of tilting blade assemblies includes two rows of tilting blade units. The two rows of tilting blade units are symmetrically arranged on both sides of the first through slots 203. Each row of tilting units includes multiple tilting blades 204 arranged at equal intervals.

[0024] Two rows of rotating blade units are aligned and parallel, and multiple conveying units 11 and multiple rotating blades 204 are staggered. The rotating mechanism 2 also includes a fixed cylinder 205 inserted into the open end of the rotating drum 202. The outer end of the fixed cylinder 205 is fixed to the bracket 201, and two symmetrically distributed second through slots 206 are opened on the outer wall of the fixed cylinder 205. A second motor 208 for driving the rotating drum 202 to rotate is installed on one side wall of the bracket 201.

[0025] The outer diameter of the fixed cylinder 205 is matched with the inner diameter of the rotating cylinder 202. The outer wall of the fixed cylinder 205 and the inner wall of the rotating cylinder 202 are both smooth surfaces. The height of the top of the conveying roller 112 is higher than the height of the upper surface of the outer shell 111, and the height of the top of the conveying roller 112 is not lower than the position height of the bottom horizontal plane of the second through groove 206. The second through groove 206 is the same size as the first through groove 203. When the first through groove 203 and the second through groove 206 coincide, the upper surface of one row of flipping units is on the same horizontal plane as the bottom horizontal plane of the second through groove 206.

[0026] In this embodiment, by setting a flipping mechanism 2 between the two conveyors 1, the marble slabs can be continuously flipped using their combined operation, greatly improving the efficiency of marble slab flipping. Furthermore, depending on the working conditions, horizontal conveying or flipping conveying can be selected, further expanding the functionality of marble slab processing and transfer to meet processing and conveying requirements.

[0027] Specifically, when the marble slab is conveyed to the conveyor 1 in the previous process, it can be conveyed according to actual needs. When it is necessary to flip the marble slab, the conveyor 1 can transport the marble slab to one side of the rotating drum 202, and then the second motor 208 drives the rotating drum 202 to rotate. The rotating drum 202 will drive the flipping blade assembly to move, thereby lifting the marble slab on the conveyor 1. At the same time, after the rotating drum 202 rotates, the second through groove 206 on the fixed cylinder 205 will be misaligned with the first through groove 203 on the rotating drum 202. Thus, the outer wall of the fixed cylinder 205 will block the first through groove 203 on the rotating drum 202, so as to prevent the marble slab from passing through the first through groove 203.

[0028] When the second motor 208 drives the drum 202 to rotate 180 degrees and then stops rotating, the marble slab has been flipped over and placed on a conveyor 1 on the opposite side. The conveyor 1 on the opposite side will then transport the marble slab to the next process.

[0029] When it is not necessary to flip the marble slabs for transport, simply control the drum 202 to not rotate. The horizontally conveyed marble slabs will pass through the first through groove 203 and the second through groove 206 (the first through groove 203 and the second through groove 206 are in an overlapping state) and be transported to the opposite conveyor 1. The opposite conveyor 1 will then transport the marble slabs to the next process.

[0030] It should be noted that the flipping mechanism 2 in this solution is only suitable for medium or thick marble slabs.

[0031] Please refer to this carefully. Figures 1-5 The conveying unit 11 includes a housing 111. Multiple conveying rollers 112 are arranged at equal intervals on the inner side of the housing 111. One of the conveying rollers 112 is connected to the drive shaft 12. The middle of each of the other multiple conveying rollers 112 is provided with a rotating shaft. The drive shaft 12 and the rotating shaft are rotatably connected to the two side walls of the housing 111 through bearings. A groove is provided on one outer side wall of the housing 111. The same number of gears 113 as the conveying rollers 112 are evenly distributed in the groove. The multiple gears 113 are respectively connected to one end of the rotating shaft and the outer wall of the drive shaft 12, and the multiple gears 113 are connected to each other through a chain 114.

[0032] In this embodiment, the conveyor 1 consists of multiple conveying units 11. These units are driven from the same end by a drive shaft 12, which in turn drives the conveyor rollers 112 via gears 113 and chains 114, achieving synchronous rotation and conveying. In this design, one end of the conveyor 1 connects and fixes the multiple conveying units 11, while the other end remains unfixed. This allows for a staggered distribution with the tilting blade assembly. When the marble is conveyed by the conveyor 1 to one side of the rotating drum 202, the tilting blade assembly can lift and tilt the marble slab.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
