[0002] Steel plates are flat steel materials cast from molten steel and pressed after cooling. When in use, steel plates need to be cut into required shapes by numerical control cutting machine tools such as laser cutting machines.

[0003] The patent with the publication number CN218503610U discloses a "laser cutting machine, including a bottom plate, and an installation frame is fixedly connected to the top of the bottom plate. Through the settings of the bottom plate, the installation frame, the laser cutting machine body, the placement plate, the fixing plate, the connecting frame, the movable groove, the threaded rod, the threaded block, the connecting block and the lifting rod, the rotation of the threaded rod can drive the threaded block, the connecting block and the placement plate to move along the inner cavity of the movable groove, so as to move the cut metal plate on the top of the placement plate to the external environment, solving the problem that since the metal plate is cut into multiple metal plates with smaller areas, and some metal plates are located at the center of the cutting platform, it is impossible for the staff to directly take away the cut metal plates".

[0004] Regarding the above related technologies, the inventor believes that the laser cutting machine lacks a dust removal device, and the high-temperature soot generated during the operation process will spread, seriously affecting the working environment and human health. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a steel plate cutting device, and the specific technical solutions are as follows:

[0006] A steel plate cutting device includes a machine tool, a guide rail installed on the top of the machine tool, a cutting mechanism installed on the top of the machine tool and moving along the guide rail, and an industrial control computer installed on one side of the machine tool and capable of controlling the cutting mechanism to cut the steel plate into corresponding shapes according to drawing software and network downloaded files. A dust suction mechanism for sucking the high-temperature soot generated during the cutting of the steel plate is arranged on one side of the cutting mechanism, and a treatment mechanism for purifying and treating the high-temperature soot is arranged on the other side of the cutting mechanism. The treatment mechanism includes a water tank fixedly arranged on the outer wall of the cutting head of the cutting mechanism.

[0007] By adopting the above technical solutions, the dust suction mechanism can suck the high-temperature soot generated during the cutting operation, reduce the diffusion of the soot, and introduce the high-temperature soot into the water in the treatment mechanism through the pressurizing and air guiding mechanism, so as to purify and remove the sulfurized smoke and metal dust in the high-temperature soot, and cool down the exhausted gas after purification.

The dust suction mechanism includes a dust suction box fixedly provided on the outer wall of the cutting head of the cutting mechanism, and a suction fan fixedly provided in the middle of the dust suction box. One end of the dust suction box is fixedly provided with a suction air pipe for sucking the high-temperature smoke and dust generated by the cutting mechanism cutting the steel plate. A maintenance door for people to perform maintenance is rotatably provided on one side of the dust suction box.

[0009] By adopting the above technical solution, after the suction fan operates, the high-temperature smoke and dust generated when the cutting head of the cutting mechanism cuts the steel plate will be sucked into the dust suction box through the suction air pipe.

[0010] Optionally, the pressurizing air guiding mechanism includes a first air pipe fixedly provided in the dust suction box at the end far from the suction air pipe, an air pressurizing pump fixedly provided on the outer wall of the top end of the first air pipe, and a second air pipe fixedly provided at one end of the air pressurizing pump and having the bottom end leading into the water body in the water tank.

[0011] By adopting the above technical solution, the air pressurizing pump can connect the first air pipe and the second air pipe, and the first air pipe and the second air pipe can introduce the high-temperature flue gas in the dust suction box into the water in the water tank.

[0012] Optionally, the stirring mechanism includes a motor fixedly provided at the bottom of the outer wall of the water tank, and a stirring member fixedly provided at the top of the output end of the motor and used for breaking the bubbles discharged from the bottom end of the second air pipe. A drain pipe is fixedly provided at the bottom of the inner wall of the water tank, and a valve located outside the water tank is fixedly installed at one end of the drain pipe.

[0013] By adopting the above technical solution, after the motor operates, it will drive the stirring member to rotate, thereby breaking the bubbles formed by the high-temperature smoke and dust passing into the water, improving the solubility of the high-temperature smoke and dust in the water, and enabling the high-temperature smoke and dust to come into fuller contact with the water.

[0014] In summary, the present utility model has at least the following beneficial effects:

[0015] 1.

Through the settings of the industrial control computer, the cutting mechanism can be controlled to cut the steel plate into corresponding shapes according to the drawing software and network downloaded files, simplifying the operation process, improving the cutting efficiency and accuracy. After the motor runs, it will drive the stirring part to rotate, thereby breaking the bubbles formed by the high-temperature soot passing into the water, increasing the solubility of the high-temperature soot in the water, enabling the high-temperature soot to come into more sufficient contact with the water, and thus improving the purification effect of the high-temperature soot.

The guide rail 11 is used to support and guide the movement of the cutting mechanism 12 on the steel plate. The cutting mechanism 12 can accurately cut the steel plate according to the shape drawn in the industrial control computer 13. The machine tool 1, the guide rail 11, the cutting mechanism 12 and the industrial control computer 13 constitute an existing numerical control cutting machine tool such as a laser cutting machine, and its internal structure and control principle have been publicly known, so no further elaboration will be made here.

[0024] The industrial control computer 13 can generate cutting path data in real time through the drawing function of drawing software such as CAD. This data is converted into instructions recognizable by the cutting mechanism 12 through the internal control system, driving the cutting mechanism 12 to cut according to the drawn shape. The industrial control computer 13 can also be connected to a remote server, allowing users to upload or download preset cutting shape files through the network, further enriching the selection and customization of cutting shapes. The above are all public technologies of numerical control cutting machine tools such as existing laser cutting machines, and will not be elaborated here.

[0025] Refer to Figure 1 , a number of shock-absorbing cushion irons 14 are fixedly arranged at the bottom edges of the machine tool 1 and the industrial control computer 13. The shock-absorbing cushion irons 14 can support and shock-absorb the machine tool 1 and the industrial control computer 13.

[0026] Refer to Figure 1 , Figure 3 and Figure 4 , on one side of the cutting mechanism 12, there is a dust suction mechanism for sucking the high-temperature smoke and dust generated during the cutting of the steel plate, and on the other side of the cutting mechanism 12, there is a treatment mechanism for purifying the high-temperature smoke and dust. The dust suction mechanism includes a dust suction box 2 fixedly arranged on the outer wall of the cutting head of the cutting mechanism 12, and a suction fan 21 fixedly arranged in the middle of the dust suction box 2. One end of the dust suction box 2 is fixedly provided with a suction air pipe 22 for sucking the high-temperature smoke and dust generated by the cutting mechanism 12 when cutting the steel plate. The bottom end of the suction air pipe 22 is directly opposite to the bottom end of the cutting head of the cutting mechanism 12. The suction fan 21 can be a negative pressure fan, a suction fan or other fans with a suction effect.

[0027] Refer to Figure 1 , Figure 3 and Figure 4 , after the suction fan 21 operates, it will suck the high-temperature smoke and dust generated by the cutting head of the cutting mechanism 12 when cutting the steel plate into the dust suction box 2 through the suction air pipe 22. A maintenance door 23 for people to repair is rotatably arranged on one side of the dust suction box 2, and people can open the maintenance door 23 to repair and maintain the internal components of the dust suction box 2.

[0028] Refer to Figure 1 , Figure 3 and Figure 4, the processing mechanism includes a water tank 3 fixedly arranged on the outer wall of the cutting head of the cutting mechanism 12. A pressure-boosting air guiding mechanism is arranged in the cutting mechanism 12 for boosting the high-temperature smoke and dust sucked by the dust suction mechanism and guiding it into the water in the water tank 3. The pressure-boosting air guiding mechanism includes a first air pipe 4 fixedly arranged in the dust suction box 2 at the end far from the air suction pipe 22, an air booster pump 41 fixedly arranged on the outer wall of the top end of the first air pipe 4, and a second air pipe 42 fixedly arranged at one end of the air booster pump 41 and with the bottom end leading into the water body in the water tank 3. The air booster pump 41 is fixedly installed on the top of the dust suction box 2. The air booster pump 41 can connect the first air pipe 4 and the second air pipe 42. The first air pipe 4 and the second air pipe 42 can guide the high-temperature flue gas in the dust suction box 2 into the water in the water tank 3.

[0029] After the suction fan 21 operates, the high-temperature flue gas sucked into the dust suction box 2 will be sent into the first air pipe 4, and after being boosted by the air booster pump 41, it will be introduced into the water in the water tank 3 through the second air pipe 42. Among them, the sulfur smoke in the high-temperature flue gas will react with the water in the water tank 3 and thus be removed. The metal dust in the high-temperature flue gas will be adsorbed by the water and thus be removed, so as to purify the high-temperature flue gas. And the heat in the high-temperature flue gas will exchange heat with the water in the water tank 3, thereby cooling the exhaust gas discharged into the workshop after purification. People can change the water in the water tank 3 to reduce the water temperature in the water tank 3.

[0030] Refer to Figure 1 、 Figure 3 and Figure 4 , a drain pipe 31 is fixedly arranged at the bottom of the inner wall of the water tank 3. One end of the drain pipe 31 is fixedly installed with a valve 32 located outside the water tank 3. The valve 32 can be a ball valve. After people open the valve 32, the drain pipe 31 will be unblocked, so as to drain the water in the water tank 3 and change the water in the water tank 3.

The stirring member 34 can be a dispersion disk, a stirring paddle and other objects that can break the bubbles and have a certain stirring effect.

[0032] After the motor 33 operates, it will drive the stirring member 34 to rotate to break the bubbles formed by the high-temperature smoke and dust passing into the water, improve the solubility of the high-temperature smoke and dust in the water, and enable the high-temperature smoke and dust to contact and react with the water more fully.

[0033] The implementation principle of a steel plate cutting device according to an embodiment of the present invention is as follows:

[0034] During use, the cutting mechanism 12 can cut the steel plate on the machine tool 1. High-temperature smoke and dust will be generated during cutting. At this time, the suction fan 21 will suck the high-temperature smoke and dust into the dust suction box 2, and send the high-temperature flue gas sucked into the dust suction box 2 into the first air duct 4 along with the exhaust of the suction fan 21. At this time, after being pressurized by the air booster pump 41, the high-temperature flue gas will be introduced into the water in the water tank 3 through the second air duct 42;

[0035] Among them, the sulfurized smoke in the high-temperature flue gas will react with the water in the water tank 3 and thus be removed, and the metal dust in the high-temperature flue gas will be adsorbed by the water and thus be removed, thereby purifying the high-temperature flue gas. The heat in the high-temperature flue gas will exchange heat with the water in the water tank 3, thereby cooling the exhaust gas discharged into the workshop after purification;

[0036] At the same time, after the motor 33 runs, it will drive the stirring member 34 to rotate to break the bubbles formed by the high-temperature smoke and dust passing into the water, improve the solubility of the high-temperature smoke and dust in the water, enable the high-temperature smoke and dust to contact and react with the water more fully, and the stirring member 34 can stir the water in the water tank 3, so that the water in the water tank 3 can contact the high-temperature flue gas more evenly, improving the purification effect of the high-temperature smoke and dust.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
