Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting of wood-based panels, in particular to a laser cutting device with a wet smoke dust removal device. Background Technique

[0002] With the progress of science and technology, in the manufacturing process of knife molds, laser cutting is used to process wood-based panels by laser cutting. However, a large amount of smoke and dust will be generated during laser cutting, and directly discharging it into the air will cause serious air pollution. For the smoke and dust generated by laser cutting, dust removal treatment needs to be carried out first. Currently, dust removal devices are mainly divided into two categories: dry type and wet type. Dry dust removal devices include bag filters, cyclone dust collectors, and electrostatic precipitators, etc. Among them, bag filters have high energy consumption, short service life, and the dust removal bags are easy to block; cyclone dust collectors have long dust removal pipelines, and it is not easy to remove fine dust; although electrostatic precipitators have good dust removal effects, they are expensive, and their dust removal devices are also easy to block. Therefore, a wet dust removal device with good dust removal effect, long service life, and low price is needed.

[0003] Generally, the wet dust removal device on the market refers to a device with several spray heads installed in a dust removal tower, a circulating sedimentation tank and a conditioning reservoir installed at the bottom of the dust removal tower, which can recycle the spray liquid and treat the dust sprayed down. However, there is a lack of a dust removal device dedicated to laser cutting equipment on the market, and ordinary dust removal devices on the market are difficult to be used in laser cutting equipment. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a laser cutting device with a wet smoke dust removal device that can not only collect and remove the smoke and dust generated by the laser cutting device.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A laser cutting device with a wet smoke dust removal device, including a frame, a workbench, an X-direction translation module installed on the frame, a Y-direction translation module installed on the X-direction translation module, a Z-direction lifting seat installed on the Y-direction translation module, and a laser cutting head installed on the Z-direction lifting group. The laser cutting head is located above the workbench, and further includes a smoke absorption cabinet, an air inlet opened at the bottom of the smoke absorption cabinet, and an exhaust port opened at the top of the smoke absorption cabinet. The frame is installed with a dust suction hood communicated with the air inlet through a pipeline, and a spraying component is installed in the smoke absorption cabinet.

[0006] Preferably, the dust suction hood is located below the workbench and extends to the entire workbench.

[0007] Preferably, the frame is installed with a translation device for driving the dust suction hood to move horizontally synchronously with the laser cutting head.

[0008] Preferably, the spraying assembly includes a water inlet, at least three horizontally arranged water pipes communicated with the water inlet, and at least three spray heads opened on the water pipes.

[0009] Preferably, at least two horizontally arranged partitions are provided on the inner wall of the smoke absorption cabinet, and at least two partitions are arranged staggeredly on the left and right inner walls of the smoke absorption cabinet.

[0010] Preferably, an umbrella-shaped cover and a vertical rod for supporting the umbrella-shaped cover are provided at the end of the air inlet. There is a gap between the end of the air inlet and the umbrella-shaped cover, and the outer diameter of the umbrella-shaped cover is larger than the outer diameter of the end of the air inlet.

[0011] The beneficial effects of the present invention are as follows: The present invention provides a laser cutting device with a wet smoke dust removal device. In practical applications, the dust generated by the laser cutting head acting on the wooden board is sucked by the dust removal device through the dust suction hood into the smoke absorption cabinet, and is fully mixed with the water droplets sprayed by the spraying assembly. After the dust is inhaled and fused with the water droplets, it falls into the drain pipe and is discharged, realizing deep purification of the dust, with high reliability and strong practicability.

[0013] Figure 2 is a sectional structural schematic diagram of the smoke dust removal device in the present invention. Detailed Embodiments

[0014] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments. The content mentioned in the embodiments does not limit the present invention.

[0015] As Figures 1 to 2 shown, a laser cutting device with a wet smoke dust removal device includes a frame 1, a workbench 2, an X-direction translation module 3 installed on the frame 1, a Y-direction translation module 4 installed on the X-direction translation module 3, a Z-direction lifting seat installed on the Y-direction translation module 4, and a laser cutting head 5 installed on the Z-direction lifting group. The laser cutting head 5 is located above the workbench 2. It further includes a smoke absorption cabinet 6, an air inlet 61 opened at the bottom of the smoke absorption cabinet 6, and an exhaust port 62 opened at the top of the smoke absorption cabinet 6. The frame 1 is installed with a dust suction hood 63 communicated with the air inlet 61 through a pipeline, and a spraying assembly is installed in the smoke absorption cabinet 6.

[0016] In practical applications, the dust generated by the laser cutting head 5 acting on the wooden board is sucked into the smoke absorption cabinet 6 by the dust removal device through the dust suction hood 63, and is fully mixed with the water droplets sprayed by the spraying assembly. After the dust is inhaled and fused with the water droplets, it falls into the drain pipe 65 and is discharged, achieving deep purification of the dust, with high reliability and strong practicability.

[0017] In this embodiment, the dust suction hood 63 is located below the workbench 2, and the dust suction hood 63 extends to the entire workbench 2. It is used to quickly and timely suck the dust generated by the laser head into the dust suction hood 63, effectively preventing the generated dust from entering the air and polluting the environment, with a higher environmental protection level.

[0018] It should be added that the frame 1 is equipped with a translation device that drives the dust suction hood 63 to move horizontally synchronously with the laser cutting head 5. By using the translation device, the dust suction hood 63 can follow the movement of the laser cutting head 5, more efficiently and accurately absorb the dust, and also achieve the above technical effects, with higher reliability.

[0019] In this embodiment, the spraying assembly includes a water inlet 64, at least three horizontally arranged water pipes 65 communicated with the water inlet 64, and at least three spray heads 66 opened on the water pipes 65. The design of more spray heads 66 strengthens the thorough fusion of the dust and the water droplets, improves the absorption rate of the dust, and the purification effect is more prominent.

[0020] In this embodiment, at least two horizontally arranged partitions 67 are provided on the inner wall of the smoke absorption cabinet 6, and at least two partitions 67 are arranged alternately on the left and right inner walls of the smoke absorption cabinet 6. Without increasing the volume of the smoke absorption cabinet 6, the flow path of the dust mixed gas in the smoke absorption cabinet 6 is extended, thereby increasing the fusion strength between the dust mixed gas and the water droplets, further improving the absorption rate of the dust, and achieving more thorough purification.

[0021] In this embodiment, an umbrella-shaped cover 68 and a vertical rod for supporting the umbrella-shaped cover 68 are provided at the end of the air inlet 61. There is a gap between the end of the air inlet 61 and the umbrella-shaped cover 68, and the outer diameter of the umbrella-shaped cover 68 is larger than the outer diameter of the end of the air inlet 61. This effectively prevents the water sprayed by the spray head 66 from flowing back into the air inlet 61, with higher reliability and stronger practicability.
