[0002] Natural stones are divided into two types: slate and granite according to their physical and chemical characteristics. Artificial stones are divided into terrazzo and synthetic stones according to the process. Terrazzo is forged from raw materials such as cement and concrete; synthetic stones are made from crushed stones of natural stones, plus adhesives, etc., and are formed by pressing and polishing. With the development of architectural design, stones have long become one of the important raw materials for construction, decoration, roads, and bridge construction. After the stones are cut, it is necessary to grind and deburr their sides. At present, when grinding the edges of stones, a large amount of dust will be generated and fly, causing environmental pollution.

[0003] In view of the above technical problems, for example, the edge grinding equipment for stone processing disclosed in the publication number CN214237499U is provided with a nozzle above the grinding wheel. When the grinding wheel grinds the stone, the nozzle can spray clean water to the contact area between the grinding wheel and the stone, so that the sprayed clean water can prevent dust from flying, and at the same time, the clean water can cool the grinding wheel and the grinding area of the stone and form wet grinding, so as to improve the service life of the grinding wheel.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides an edge grinding device for stone processing, including a fixed frame 1. A material pressing mechanism 2 for preventing material deviation is arranged in the inner cavity of the fixed frame 1. A grinding mechanism 3 for stone edge grinding is also arranged in the inner cavity of the fixed frame 1. A conveying mechanism 4 for limiting and feeding is arranged in the inner cavity of the fixed frame 1. The electric push rod 21 in the material pressing mechanism 2 is fixedly installed on the top of the fixed frame 1:

[0024] The output end of the electric push rod 21 is fixedly installed with a first connecting plate 22. A spring 23 is welded to the bottom of the first connecting plate 22. A second connecting plate 24 is welded to the bottom of the spring 23. A pressing wheel 26 is welded to the bottom of the second connecting plate 24. A vertical rod 25 is fixedly installed on the top of the second connecting plate 24

[0025] Among them, the spring 23 is located outside the vertical rod 25. The top end of the vertical rod 25 penetrates and slides above the first connecting plate 22. A round plate is fixedly installed at the top end of the vertical rod 25, realizing the advantages of stable wheel pressing on the stone, and at the same time ensuring the stable movement of the stone while wheel pressing.

[0026] When pressing the material:

[0027] Use the electric push rod 21 to push the first connecting plate 22 downward until it contacts the stone, and then move downward further. Move according to the required direction. During the secondary downward movement, the spring 23 will be compressed, and the resilient spring 23 will push and press the second connecting plate 24. The second connecting plate 24 drives the pressure wheel 26 to stabilize the stone. At this time, when the stone is driven to move, the pressure wheel 26 rotates accordingly to achieve stable wheel pressing operation.

[0028] Preferably, the grinding mechanism 3 includes a support assembly, a transmission assembly, and an abrasive assembly. The support assembly is arranged on the inner side wall of the fixed frame 1, the transmission assembly is arranged above the support assembly, and the abrasive assembly is arranged below the support assembly.

[0029] As Figure 2 shown, both the first fixed plate 32 and the second fixed plate 33 in the support assembly are fixedly installed on the inner side wall of the fixed frame 1. The first fixed plate 32 and the second fixed plate 33 are arranged at intervals up and down. The motor 31 is fixedly installed on the top of the fixed frame 1. The motor 31 provides power output during edge grinding, and the first fixed plate 32 and the second fixed plate 33 play a role in connection and support.

[0030] As Figure 2 shown, the third grinding wheel 34, the second grinding wheel 35, and the first grinding wheel 36 in the abrasive assembly are all located at the bottom of the first fixed plate 32. Transmission rods are fixedly installed on the tops of the third grinding wheel 34, the second grinding wheel 35, and the first grinding wheel 36. The transmission rods are rotatably connected between the first fixed plate 32 and the second fixed plate 33. The output shaft of the motor 31 is key-connected to the top end of the transmission rod. The first grinding wheel 36 can perform primary grinding, the second grinding wheel 35 can perform fine grinding, and the third grinding wheel 34 can grind the edge corners of the stone.

[0031] As Figure 2 shown, the transmission assembly includes a belt and belt pulleys. A belt pulley is fixedly installed at the top end of the transmission rod, and a belt is sleeved outside the belt pulley, which plays a role in transmitting the rotational force.

[0032] During edge grinding:

[0033] Directly operate the motor 31 to drive the transmission rod on the first grinding wheel 36 to rotate. Through the transmission of the belt and belt pulleys, the transmission rod on the second grinding wheel 35 is driven to rotate. The transmission on the second grinding wheel 35 will also drive the transmission rod on the third grinding wheel 34 to rotate through the transmission of the belt and belt pulleys, so as to achieve the simultaneous rotation of the third grinding wheel 34, the second grinding wheel 35, and the first grinding wheel 36, and thus perform edge grinding operations on the moving stone.

[0034] Furthermore:

[0035] As shown in the figure, the conveyor belt 43 in the conveying mechanism 4 is rotatably connected to the inside of the fixing frame 1. A bracket 41 is bolted to the end of the inner side wall of the fixing frame 1. A limiting wheel 42 is rotatably connected to the inner side wall of the bracket 41, which can realize the alignment and limitation of the stone during feeding and can drive the stone to move.

[0036] First, place the stone on the top of the conveyor belt 43, and the stone can be fed by moving forward with its side in contact with the limiting wheel 42. When moving, the material can be pressed during wheel pressing. At the same time, when contacting the third grinding wheel 34, the second grinding wheel 35, and the first grinding wheel 36, the three rotate to complete the edge grinding operation in sequence.

[0037] In addition, during the edge grinding process of the stone, it can be washed or dust-reduced through the spray pipe.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
