Description

Technical Field

[0002] CO2 cutting is an industrial processing technology that uses a laser beam to convert CO2 gas into laser energy, and then focuses the laser beam on the workpiece to cut, weld or mark with high energy density. This technology is usually used for the processing of metal materials, such as steel, aluminum, etc. CO2 cutting has the advantages of fast, accurate and highly automated, and has been widely used in the field of industrial manufacturing.

[0003] A carbon dioxide five-axis cutting head dust suction device in the prior art (Announcement No.: CN219746642U) starts the cutting knife and the exhaust fan at the same time, the cutting knife cuts the material, and the dust generated is sucked into the first pipe through the barrel cover and transported to the storage box. The dust splashed to the surrounding area is sucked into the second pipe through the circular hole below the cutting knife, and then transported to the storage box. The mutual cooperation of the first dust suction component and the second dust suction component is conducive to better adsorption of dust. However, the device is easy to suck the cut small-volume parts into the first pipe during use, and it is not possible to distinguish between dust and parts well. At the same time, the filter plate will gradually become clogged during use, and it needs to be frequently disassembled and cleaned, which reduces the dust suction efficiency. Therefore, it is urgent to design a carbon dioxide cutting head dust suction device that can avoid sucking away parts and has high dust suction efficiency. Utility Model Content

[0023] When in use, a dust collection mechanism is formed by arranging a first dust collection box 2, a second dust collection box 7 and a dust collecting funnel 8. The dust passes through the first dust collection box 2 and the second dust collection box 7 in sequence with the air flow. The dust and parts can be distinguished and isolated through the dust collection holes 15 at the bottom of the first dust collection box 2 to prevent the parts from entering the dust collection mechanism. The dust is filtered and blocked by the filter plate 11 in the second dust collection box 7, and then stays in the dust collecting funnel 8 for centralized collection. During the dust collection process, the air flow drives the fan 10 to rotate, and then drives the bending shaft 12 to rotate. The bending shaft 12 drives the scraper 13 to clean one side of the filter plate 11 to avoid dust accumulation and affect the circulation of air flow. The rotation of the bending shaft 12 can drive the spiral blade 14 to rotate. The spiral blade 14 can be made of low-density and wear-resistant polyethylene material. The rotation of the spiral blade 14 can block dust particles in the air flow, reduce the collision of dust particles with the filter plate 11, increase the service life of the filter plate 11, reduce the number of shutdowns for maintenance of the filter plate 11, and thus improve the dust collection efficiency of the equipment.

[0024] In this embodiment, a smooth inclined surface for draining dust is provided at the bottom of the second dust collection box 7, a valve is provided at the bottom outlet of the dust collecting funnel 8, a protective cover 3 is fixedly installed at the bottom of the first dust collection box 2, an annular pipe 9 is fixedly installed in the protective cover 3, a plurality of jet pipes 4 are threadedly connected around the annular pipe 9, and the plurality of jet pipes 4 are all inclinedly arranged, and a plurality of avoidance grooves adapted to the jet pipes 4 are provided around the bottom of the protective cover 3, a support plate is fixedly installed on one side of the first dust collection box 2, a blower 5 is fixedly installed at the bottom of the support plate, an air inlet end of the blower 5 is connected to one end of the air suction cover 6 through an air pipe, and an air outlet end of the blower 5 is connected to the annular pipe 9 through the air pipe through the protective cover 3.

[0025] When in use, the blower 5 generates an air flow with a certain air pressure to suck the dust into the second dust suction box 7 for filtering and collection. The filtered air flow is discharged into the annular duct 9 through the air outlet end of the blower 5, and then the plate around the cutting head body 1 is blown through multiple air jet pipes 4 to blow away dust, debris and other impurities on the surface of the plate to prevent these impurities from affecting the cutting accuracy. The protective cover 3 is made of silicone rubber. Silicone rubber has the advantages of high temperature resistance and elasticity. It can protect the cutting head body 1. When encountering obstacles, it can play a buffering role through its elastic deformation to prevent the obstacles from directly contacting the cutting head body 1, thereby improving the practicability of the equipment.

The bending shaft 12 drives the scraper 13 and the spiral blade 14 to rotate. The scraper 12 can clean one side of the filter plate 11 during its rotation. The spiral blade 14 can block most of the dust particles from directly colliding with the filter plate 11, thereby protecting the filter plate 11. The filtered dust and other impurities are then collected through the dust collecting funnel 8, thereby avoiding frequent maintenance of the filter plate 11 and improving the working efficiency of the equipment. The jet system composed of the annular pipe 9 and the jet pipe 4 is used to clean the cutting area, thereby improving the cutting accuracy of the cutting head body 1.
