Description

Technical Field

[0001] The utility model relates to the field of cutting devices, in particular to a cutting device with a dustproof structure. Background Art

[0002] The circular saw is an efficient and precise cutting tool, mainly used for cutting materials such as steel, wood, and plastic. The working principle of the circular saw is to drive the saw blade to rotate at high speed through a motor, and use the saw teeth to cut the material into the required size. During the cutting process, the auxiliary tool holder and the guide rail play the role of fixing the workpiece and the saw blade to ensure cutting accuracy and efficiency. In addition, the circular saw machine can also adjust the height and translation of the saw blade according to the different materials to achieve the best cutting effect. It is widely used in furniture manufacturing, construction and other fields. In the field of construction, circular saws are generally used to cut tiles or bricks. A large amount of dust will be generated during the cutting process. In order to reduce the generation of dust, water needs to be sprayed on the blade during the cutting process. This dust removal method consumes a lot of water and is inconvenient to operate. For this reason, a cutting device with a dustproof structure is proposed. Summary of the invention

[0012] During use, the rotor in the circular saw body will drive the drive shaft to rotate. After the drive shaft rotates, it will drive the fan blades and the worm gear shaft to rotate. After the fan blades rotate, negative pressure will be formed in the volute, allowing outside air to enter the circular saw body and the air pipeline. The air entering the circular saw body will dissipate the heat for it. The air entering the air pipeline will blow into the dust cover. When the air blows into the dust cover, the worm gear shaft will drive the impeller in the turbine pump to rotate, causing water to be sprayed out through the atomizing nozzle.

[0021] Specifically, the rotor in the circular saw body 1 will drive the driving shaft 503 to rotate. After the driving shaft 503 rotates, it will drive the fan blades 502 and the worm gear shaft 604 to rotate. After the fan blades 502 rotate, negative pressure will be formed in the volute 501, allowing the outside air to enter the circular saw body 1 and the air pipeline 504. The air entering the circular saw body 1 will dissipate the heat for it, and the air entering the air pipeline 504 will be blown to the inside of the dust cover 505.

[0022] The water supply mechanism 6 includes a turbine pump 601 fixed to the back of the volute 501, a water inlet 602 and a water outlet 603 are fixedly installed on the turbine pump 601, a worm shaft 604 is connected to the turbine pump 601, the water outlet 603 is connected to a water pipeline 605, an atomizing nozzle 606 is fixedly installed at the end of the water pipeline 605, screws are provided on the turbine pump 601, the turbine pump 601 is fixed to the volute 501 by the screws, an installation port is opened at the connection between the air pipeline 504 and the dust cover 505, the atomizing nozzle 606 is installed at the connection between the air pipeline 504 and the dust cover 505 through the installation port, one end of the water pipeline 605 is connected to the turbine pump 601, and the other end of the water pipeline 605 is connected to the atomizing nozzle 606.

[0023] Specifically, when air blows toward the inside of the dust cover 505, the worm gear shaft 604 will drive the impeller in the turbine pump 601 to rotate, causing water to be sprayed out through the atomizing nozzle 606. The water sprayed out through the atomizing nozzle 606 will be fully mixed with the air in the air pipeline 504 and enter the dust cover 505, so that the water and the dust generated by cutting are fully in contact to form mud.

When it is actually used, the cutting saw blade 4 is first driven to rotate by the rotor inside the circular saw body 1. When the cutting saw blade 4 rotates, the rotor inside the circular saw body 1 will also drive the driving shaft 503 to rotate. After the driving shaft 503 rotates, it will drive the fan blades 502 and the worm gear shaft 604 to rotate. After the fan blades 502 rotate, negative pressure will be formed in the volute 501, so that the outside air enters the inside of the circular saw body 1 and the air pipeline 504. The air entering the inside of the circular saw body 1 will dissipate the heat for it. The air entering the air pipeline 504 will blow into the dust cover 505. When the air blows into the dust cover 505, the worm gear shaft 604 will drive the impeller in the turbine pump 601 to rotate, so that water is sprayed out through the atomizing nozzle 606. The water sprayed through the atomizing nozzle 606 will be fully mixed with the air in the air pipeline 504 and enter the dust cover 505, so that the water and the dust generated by cutting are fully in contact to form mud, thereby reducing the generation of dust.
