Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a sandblasting device for stone surface treatment. Background Technology

[0002] Sandblasting machines use compressed air as power to form a high-speed jet that propels abrasive materials (steel grit, quartz sand, corundum, glass sand, resin sand, etc.) at high speed onto the surface of the workpiece to be treated. This causes changes in the mechanical properties of the workpiece's outer surface. Sandblasting can remove impurities, discoloration, and oxide layers from the workpiece surface, while also roughening the surface, eliminating residual stress, and increasing the surface hardness.

[0003] A Chinese patent, CN220113086U, describes a sandblasting machine for stone processing. It includes a conveying mechanism to transport the stone, followed by a sandblasting mechanism to sandblast the stone surface. A reciprocating mechanism ensures comprehensive sandblasting. A recycling mechanism collects any sandblasting material that falls into the base during the process, preventing waste. However, the angle and height of the sandblasting head are not adjustable. Over-sandblasting can expose more of the underlying stone color, creating a noticeable color difference between the over-sanded areas and the under-sanded areas, affecting the overall aesthetics of the stone. For example, over-sandblasting can lead to uneven color depths in colored marble, damaging its original color and pattern. Furthermore, sandblasting edges is inconvenient. Therefore, this patent proposes a sandblasting device for stone surface treatment to address these issues. Utility Model Content

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] like Figure 1-4 As shown, the present invention proposes a sandblasting device for stone surface treatment, comprising a hollow base 1 and a frame 2 connected above the base 1. A conveyor 12 is installed inside the base 1, and a sand box 13 is fixedly installed at the top of the base 1. A collection hopper 11 is installed below the conveyor 12 and a sandblasting circulation component is connected to the sand box. A U-shaped frame 3 with its opening facing downward is installed inside the base 1. A sandblasting head 6 is installed below the U-shaped frame 3 and its rear side is connected to the bottom of the sand box 13 through a flexible hose. A drive mechanism is installed inside the U-shaped frame 3 to drive the sandblasting head 6 to move left and right and adjust its front and back angle. An adjustment unit for adjusting the height of the U-shaped frame 3 is installed at the top of the frame 2.

[0023] In an optional embodiment, the adjustment unit includes two first hydraulic cylinders 4 vertically disposed at the top of the frame 2, the telescopic ends of the two first hydraulic cylinders 4 being connected to the top of the U-shaped frame 3.

[0024] It should be noted that, since sandblasting is required for stones of different sizes and thicknesses, if the position of the sandblasting head is fixed, spraying thicker stones will damage the stone surface, while spraying thinner stones will result in insufficient sandblasting intensity due to the distance. Therefore, if sandblasting is required for stones of different sizes, the distance between the sandblasting head and the stone needs to be changed. At the same time, to achieve different effects, the angle of the sandblasting head needs to be adjusted. The two first hydraulic cylinders 4 drive the U-shaped frame 3 to move up and down, changing the height of the sandblasting head, thereby changing the distance between the sandblasting head 6 and the stone. By changing the angle of the sandblasting head 6 through the drive mechanism, the sandblasting head 6 is connected to the sandblasting circulation component to supply sand to the inside of the sand box 13.

[0025] In an optional embodiment, the drive mechanism includes a motor 51, an adjusting roller 52, a moving part 53, a limiting rod 54, and a rotating assembly. The motor 51 is located on the left side of the U-shaped frame 3. One end of the adjusting roller 52 is coaxially connected to the output shaft of the motor 51, and the other end is rotatably connected to the right side wall of the U-shaped frame 3. The limiting rod 54 is connected between the left and right walls of the U-shaped frame 3. The moving part 53 is slidably disposed on the limiting rod 54, and the rotating assembly is disposed on the moving part 53.

[0026] In an optional embodiment, the adjusting roller 52 is provided with a sliding groove, and the top end of the moving member 53 is provided with a sliding shaft that is slidably connected to the inner wall of the sliding groove.

[0027] It should be noted that the starting motor 51 drives the adjusting roller 52 to rotate, causing the moving part 53 to move left and right continuously, thereby sandblasting the stone below. The limiting rod 54 is used to limit the moving part 53 to prevent it from deflecting during movement, and also drives the rotating component to rotate.

[0028] In an optional embodiment, the rotating assembly includes a connecting frame 71, a second hydraulic cylinder 72, and a sliding frame 73. The connecting frame 71 is hinged to the bottom end of the moving member 53, and the sliding frame 73 is slidably disposed on the front side of the connecting frame 71. The moving member 53 is connected to a fixed rod, and the second hydraulic cylinder 72 is hinged between the fixed rod and the sliding frame 73. The sandblasting head 6 is connected to the top wall of the connecting frame 71, and its outlet faces downward.

[0029] In an optional embodiment, a groove is provided on the front side of the connecting frame 71, and the sliding frame 73 is slidably disposed in the groove and extends the front side of the connecting frame 71.

[0030] It should be noted that when adjusting the angle of the sandblasting head 6, the second hydraulic cylinder 72 is activated. The telescopic rod of the second hydraulic cylinder 72 retracts, pulling the connecting frame 71. The connecting frame 71 is L-shaped. During adjustment, the connecting frame 71 drives the sandblasting head 6 to rotate together. After rotation, it is convenient to sandblast different types of stone.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
