Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to an intelligent laser cutting device for zoned dust removal. Background Technology

[0002] Laser cutting machines are widely used due to their high precision and fast processing efficiency. Under the irradiation of the laser beam, the surface of the material is quickly heated to the ignition temperature, and then undergoes a violent combustion reaction with oxygen, releasing a large amount of heat. This causes small pores filled with steam to form inside the material, which are surrounded by molten metal walls. These steam and molten substances are carried away by the auxiliary airflow and float in the workshop, forming dust and smoke.

[0003] The hazards of smoke and dust are easily overlooked by operators. The high temperature generated by the laser acts on the processed material, producing a large amount of steam and smoke. These fumes often contain a large number of chemical components, which are extremely harmful to the human body. In addition, some gases produced by laser cutting (such as carbon dioxide) are more likely to damage the human respiratory system.

[0004] While existing laser cutting equipment has dust removal capabilities, the fans come into contact with the metal particles during the conveying process. The metal particles collide under high-speed influence, which can lead to electrical equipment failure over time. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent laser cutting device for zoned dust removal. The screen plate inside the dust removal air box can intercept and filter the smoke and dust entering the air box, preventing some metal particles from entering the pipeline with the smoke and affecting the fan structure, thus solving the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent laser cutting device for zoned dust removal, comprising a dust removal processing table, a dust removal air box at one end of the dust removal processing table, a ball bearing support plate at the other end of the dust removal processing table, a laser cutting unit above the dust removal processing table, wherein a toothed plate is provided on the outer surface of the dust removal processing table, horizontal guide rails are provided on both sides of the toothed plate, and limit shaft plates are provided at both ends of the horizontal guide rails, three sets of collection trolleys are provided below the dust removal processing table, a support frame is provided below the toothed plate, the support frame is connected to the dust removal processing table by bolts, a shaft frame air duct is provided below the support frame, and a dust suction air chamber is provided below the shaft frame air duct.

[0007] Furthermore, the collection trolley is located below the dust suction chamber, wherein the bottom of the collection trolley is provided with pulleys, and a crossbeam is provided between the dust suction chambers, and the crossbeam is connected to the dust removal processing table by bolts.

[0008] Furthermore, eaves are provided on both sides of the crossbeam, and the eaves are connected to the crossbeam by bolts. Hydraulic foot supports are provided around the bottom of the dust removal processing table, and a cable tray is provided above the hydraulic foot supports. The eaves can prevent falling dust from scattering in areas other than the collection trolley, thereby improving the dust collection efficiency.

[0009] Furthermore, a top cover is provided above the shaft frame air duct, and the top cover is connected to the shaft frame air duct through a slot. Air vents are provided on both sides of the shaft frame air duct. One end of the shaft frame air duct is provided with an air duct outlet, which extends into the interior of the dust removal air box. The air inside the shaft frame air duct is drawn away to form a negative pressure. At this time, the dust generated by cutting will be sucked into the interior of the shaft frame air duct by the air vents on both sides. During the process of absorbing dust, some dust particles will sink into the truck bed after contacting the object surface, while the remaining smaller particles and smoke will enter the dust removal air box through the shaft frame air duct.

[0010] Furthermore, the dust removal air box has two air chambers inside, with a screen plate between them. The screen plate is connected to the dust removal air box via a slot. A guide fan is provided on one side of each air chamber, and a fan hose is provided on the outside of the guide fan. A door is provided on the outside of the dust removal air box, and the door is rotatably connected to the dust removal air box via a hinge.

[0011] Furthermore, the dust extraction chamber is configured with a conical structure, and an insert plate is provided inside the shaft frame duct. The insert plate is slidably connected to the shaft frame duct. A guide plate is provided on the outer surface of the insert plate, and a herringbone plate is provided between the guide plates. The guide plate and the insert plate are connected by a slot, and the herringbone plate and the insert plate are configured as an integral structure. The herringbone plate can collect particulate matter in the flue gas through a chip collection groove, causing it to fall into the lower truck bed for recycling.

[0012] Furthermore, the guide plate is configured as a triangular structure, located inside the windshield slot, and the inner side of the herringbone plate is provided with a chip retention groove. The shaft frame air duct is installed above the crossbeam, and the guide plate and windshield slot are distributed in a corresponding manner. The design of the guide plate can avoid strong airflow collision on both sides.

[0013] Furthermore, the laser cutting unit includes a gantry support shaft and a horizontal slide shaft. The gantry support shaft is slidably connected to the dust removal processing table via a horizontal guide rail. A motor module is provided at one end of the gantry support shaft, and a lifting cutter is provided on one side of the gantry support shaft. The lifting cutter is slidably connected to the gantry support shaft. The gantry support shaft, together with the horizontal slide shaft and the lifting cutter, can achieve multi-angle and directional cutting adjustments.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this invention, the shaft frame duct is horizontally placed below the toothed plate, with one end connected to the dust removal air box. The dust removal air box is connected to the external dust removal fan equipment through a pipe. During operation, the air inside the shaft frame duct is drawn out to form a negative pressure. At this time, the dust generated by cutting is sucked into the shaft frame duct by the air windows on both sides. During the process of absorbing dust, some dust particles will sink into the truck bed after contacting the surface of the object. The remaining smaller particles and flue gas will enter the dust removal air box through the shaft frame duct. The screen plate inside the dust removal air box can intercept and filter the dust entering the air box, preventing some metal particles from entering the pipe with the flue gas and affecting the fan structure.

[0016] 2. In this invention, the outer side of the insert plate is provided with two structures, namely a guide plate and a fishbone plate. The guide plate is distributed in correspondence with the windshield slot. The design of the guide plate can avoid strong airflow collision on both sides. The fishbone plate can collect particulate matter in the flue gas through the chip collection groove, so that it falls into the truck bed below for recycling. Attached Figure Description
