Description

Technical Field

[0001] This utility model relates to the field of stone cutting technology, specifically a dust reduction mechanism for stone cutting machines. Background Technology

[0002] Stone materials are divided into natural stone and artificial stone, both of which can be used as building decoration materials. Natural stone refers to stone materials extracted from natural rock formations and processed into block or slab shapes. Granite and marble are the main natural stone materials used for building decoration. During the processing of natural stone, cutting machines are used to cut the stone to meet different architectural and decorative needs.

[0003] For example, utility model patent CN221985480U discloses a dust suppression mechanism for a stone cutting machine. This utility model utilizes a combination of structures such as a strip plate, a cutting mechanism, a water spraying mechanism, and a storage mechanism to recycle and reuse wastewater, reducing the demand for fresh water and helping to conserve limited water resources. Furthermore, its wastewater recycling and re-sedimentation process is relatively simple, requiring no additional investment of manpower and resources. Operators only need to periodically clean the sedimentation tank and check the equipment's operation to ensure effective dust suppression.

[0004] However, the existing technology used in the dust suppression mechanism of the stone cutting machine relies solely on water spray pipes to spray water onto the stone for dust suppression. When the cutting machine is cutting the stone, the sprayed water source is difficult to penetrate into the cutting surface in time, which can easily cause a small amount of dust to overflow and affect the dust suppression effect. Utility Model Content

[0005] This utility model provides a dust reduction mechanism for a stone cutting machine to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a dust suppression mechanism for a stone cutting machine, comprising a hollow cutting table, and further comprising: a fixed frame disposed on the top surface of the hollow cutting table, a positioning rod disposed on one side of the fixed frame, a spray pipe disposed at one end of the positioning rod, and dust suction hoods installed on both sides of the fixed frame; a filter box disposed on the bottom surface of the hollow cutting table, a slot being provided on one side of the filter box, a filter drawer being inserted into the slot, and a negative pressure fan being installed on the surface of the filter box away from the filter drawer; and a water pump disposed on the outer surface of the filter box, with a scrubbing air spray pipe passing through the output end of the water pump.

[0007] As a preferred embodiment of this utility model, a drive assembly is fixedly installed on one side of the fixed frame, and a cutting machine is fixedly installed at the bottom of the drive assembly. The drive assembly is used to drive the cutting machine to move.

[0008] As a preferred technical solution of this utility model, the driving component includes a servo motor fixedly mounted on one side of the fixed frame, and a threaded screw fixedly mounted on the output end of the servo motor. An electric push rod is threadedly connected to the surface of the threaded screw. The servo motor drives the threaded screw to rotate, causing the electric push rod to reciprocate laterally.

[0009] As a preferred technical solution of this utility model, a collection pipe is fixedly provided on the top surface of the dust collection hood, and one end of the collection pipe is connected to the inside of the filter box. The dust collection hood and the collection pipe are used to absorb smoke and dust.

[0010] As a preferred embodiment of this utility model, a microporous filter plate is fixedly provided on the bottom surface of the filter drawer, a handle is fixedly installed on one side of the filter drawer, and a sealing strip is fixedly provided on the inner wall of the slot. The sealing strip is used to seal the connection between the filter drawer and the filter box.

[0011] As a preferred embodiment of this utility model, a water pump is provided through the input end of the water pump, one end of the water pump is provided through the inside of the filter box, and the air washing nozzle is fixedly provided on the inner wall of the filter box. The air washing nozzle is used to collect the gas in the collection pipe to reduce dust.

[0012] As a preferred technical solution of this utility model, a drain pipe is provided through the bottom of the outer surface of the filter box, a valve is fixedly installed on the surface of the drain pipe, a limit groove is opened on the top surface of the fixing frame, the top of the electric push rod is slidably disposed inside the limit groove, and the valve controls the opening and closing of the drain pipe.

[0013] Compared with the prior art, this utility model provides a dust suppression mechanism for stone cutting machines, which has the following beneficial effects: This dust suppression mechanism for stone cutting machines, consisting of a spray pipe, a dust suction hood, and a negative pressure fan, works as follows: During stone cutting, a water pump draws clean water from the bottom of the filter box and sprays it onto the stone surface through the spray pipe, reducing dust generated during cutting. Simultaneously, the negative pressure fan draws air out of the filter box, creating suction that captures and collects the overflowing dust into the filter box through the collection pipe and dust suction hood. This combination of spray dust suppression and negative pressure dust suction provides a more comprehensive and effective dust suppression solution.

[0014] This dust suppression mechanism for stone cutting machines, through the setup of a filter drawer and a scrubbing nozzle, collects mixed gas from the collection pipe and dust hood. After entering the filter box, the gas flows towards the negative pressure fan, where the scrubbing nozzle sprays water onto the mixed gas, causing the mixed solid dust to be adsorbed and suppressed, preventing secondary dust generation. The filter drawer and microporous filter plate filter impurities from the water, allowing the water to be repeatedly recycled for use in the spray pipe and scrubbing nozzle, thus saving water resources and reducing processing costs.

The filter drawer 7 and the microporous filter plate 14 filter the impurities in the water, so that the water can be repeatedly recycled for the spray pipe 4 and the scrubbing nozzle 10, which helps to save water resources and reduce processing costs.

[0019] Specifically, a drive assembly 11 is fixedly installed on one side of the mounting bracket 2, and a cutter 12 is fixedly installed at the bottom of the drive assembly 11.

[0020] In this embodiment, the drive component 11 is used to drive the cutting machine 12 to reciprocate on the surface of the fixed frame 2.

[0021] Specifically, the drive assembly 11 includes a servo motor 111 fixedly mounted on one side of the mounting frame 2. A threaded screw 112 is fixedly mounted on the output end of the servo motor 111, and an electric push rod 113 is threadedly connected to the surface of the threaded screw 112.

[0022] In this embodiment, the servo motor 111 drives the threaded screw 112 to rotate, which in turn drives the electric push rod 113 to move, and the electric push rod 113 drives the cutting machine 12 to rise and fall.

[0023] Specifically, a collection pipe 13 is fixedly installed on the top surface of the dust hood 5, and one end of the collection pipe 13 is connected to the inside of the filter box 6.

[0024] In this embodiment, the dust hood 5 captures the overflowing dust and transports it to the interior of the filter box 6 through the collection pipe 13.

[0025] Specifically, a microporous filter plate 14 is fixedly installed on the bottom surface of the filter drawer 7, a handle is fixedly installed on one side of the filter drawer 7, and a sealing strip is fixedly installed on the inner wall of the slot.

[0026] In this embodiment, the sealing strip is used to seal the connection between the filter drawer 7 and the filter box 6, and the microporous filter plate 14 is used to filter and purify the water source.

[0027] Specifically, a water pump 9 has a water pump pipe installed at its input end, and one end of the water pump pipe is installed inside the filter box 6. The air washing nozzle 10 is fixedly installed on the inner wall of the filter box 6.

[0030] In this embodiment, the limiting groove is used to limit the electric push rod 113.

[0031] The working principle and usage process of this utility model are as follows: First, the stone is placed on the hollow cutting table 1. When cutting the stone, the water pump 9 draws out the clean water source at the bottom of the filter box 6 and sprays it onto the cut surface of the stone through the spray pipe 4 to reduce the dust generated during stone cutting. Then, the servo motor 111 is turned on, which drives the threaded screw 112 to rotate, causing the electric push rod 113 to drive the cutting machine 12 to move back and forth horizontally. The electric push rod 113 drives the cutting machine 12 to press down and cut the stone. Then, the negative pressure fan 8 is turned on to draw the air out of the filter box 6 to generate suction. The overflowing dust is captured and collected into the filter box 6 through the collection pipe 13 and the dust suction hood 5. The dust suppression mechanism that combines spray dust suppression and negative pressure dust suction has a more comprehensive and better dust suppression effect. Afterwards, the mixed gas collected by the collection pipe 13 and the dust hood 5 enters the filter box 6 and flows towards the negative pressure fan 8. The washing air nozzle 10 sprays water onto the mixed gas, so that the mixed solid dust is adsorbed and reduced, avoiding secondary dust. The filter drawer 7 and the microporous filter plate 14 filter the impurities in the water, so that the water can be repeatedly recycled for the spray pipe 4 and the washing air nozzle 10, which helps to save water resources and reduce processing costs. Next, pull the handle to open the filter drawer 7 and clean the impurities on the microporous filter plate 14.
