Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a laser cutting machine that is easy to clean. Background Technology

[0002] A laser cutting machine uses a laser emitted from a laser source to focus a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] Most laser cutting machines on the market are inconvenient to clean and cannot automatically unload materials, which easily leads to the accumulation of workpiece fragments on the machine tool, requiring manual cleaning and wasting time. After cutting, the cut workpieces also need to be manually removed, reducing work efficiency. Therefore, this utility model proposes a laser cutting machine that is easy to clean to solve the above problems. Utility Model Content

A slide rail is provided on the right side of the base. A connecting rod is fixedly connected to the outer side of the second bend. The bottom end of the connecting rod is slidably connected to the inside of the slide rail. A cylinder is fixedly installed on the right side of the base. The output end of the cylinder is fixedly connected to the bottom end of the connecting rod.

[0007] A further improvement is that the dust removal mechanism includes a bag filter, a fan, a suction pipe, an exhaust pipe, and a delivery pipe. The bag filter is located on the right side of the base, and the fan is located on the right side of the bag filter. The input end of the fan is connected to the top of the bag filter through the suction pipe, and the bottom of the bag filter is connected to one end of the second bend through the delivery pipe. The output end of the fan is connected to the exhaust pipe.

[0008] A further improvement is that the gas pipeline is equipped with a spark catcher, which includes a duct, a rotating shaft, a small shaft, a partition, and rotating guide vanes. The bottom of the spark catcher is equipped with a storage tank.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-5 As shown, this embodiment proposes a laser cutting machine that is easy to clean, including a base 1 and a ramp 2. The ramp 2 is located on the right side of the base 1, and a support frame 5 is fixedly connected to the left side of the ramp 2. A laser generator 6 is fixedly installed on the top of the support frame 5. A fixture 7 is located on the left side of the support frame 5, and a rotating platform 16 is located on the left side of the fixture 7. A dust collection mechanism is located on the right side of the base 1, and a dust removal mechanism is located on one side of the dust collection mechanism. One end of the pipe is passed through the interior of the fixture 7 and continues to move forward until the cutting point of the pipe is located below the laser generator 6. The rotating platform 16 is equipped with a rotary motor, sprockets and chains, which can drive the two rotating wheels at the top to rotate in the same direction. The pipe contacts the rotating wheels and rubs against each other, causing the pipe to rotate. The laser generator 6 emits a laser to automatically cut the pipe. The cut pipe is automatically rolled out to the outside through the ramp 2. Smoke and dust are generated during the cutting process. They are first collected by the dust collection mechanism and then transported to the dust removal mechanism for processing.

[0021] The dust collection mechanism includes a first bend 8, a telescopic pipe 9, a second bend 10, a connecting rod 11, a slide rail 12, and a cylinder 13. The first bend 8 is fixedly connected to the right side of the base 1. One end of the first bend 8 is connected to the second bend 10 via the telescopic pipe 9. A slide rail 12 is provided on the right side of the base 1. A connecting rod 11 is fixedly connected to the outer side of the second bend 10, and the bottom end of the connecting rod 11 is slidably connected to the inside of the slide rail 12. A cylinder 13 is fixedly installed on the right side of the base 1, and the output end of the cylinder 13 is fixedly connected to the bottom end of the connecting rod 11. The fan 18 draws air from inside the bag filter 17, creating a negative pressure inside the bag filter 17. The bag filter 17 is connected to the second bend 10 via the air supply pipe 21. The first bend 8 and the second bend 10 are connected to each other via the telescopic pipe 9. The first bend 8 is directly opposite the cutting point of the laser generator 6, while the second bend 10 is directly opposite the cutting pipe. This is used to draw in the smoke and dust from the cutting point and the inside of the pipe, and transport it to the inside of the bag filter 17 for processing, separating the dust from the air, which facilitates cleaning of the laser cutting machine.

[0022] The dust removal mechanism includes a bag filter 17, a fan 18, a suction pipe 19, an exhaust pipe 20, and a gas delivery pipe 21. The bag filter 17 is located on the right side of the base 1, and the fan 18 is located on the right side of the bag filter 17. The input end of the fan 18 is connected to the top of the bag filter 17 through the suction pipe 19, and the bottom of the bag filter 17 is connected to one end of the second bend pipe 10 through the gas delivery pipe 21. The output end of the fan 18 is connected to the exhaust pipe 20. After the dust-laden gas enters the bag filter 17... Large dust particles enter the dust hoppers of each unit through the guide device and fall directly into the dust hopper due to inertial separation. The remaining dust-laden gas rises into the filter bag area, where the dust is trapped on the outer surface of the filter bag. The purified gas enters the clean air chamber through the filter bag opening and is discharged into the atmosphere by the fan 18 and the exhaust pipe 20. As filtration proceeds, the dust on the outer surface of the filter bag thickens, and the resistance of the bag filter 17 increases. When the resistance reaches the set value, the dust removal device is activated, and the filter bag expands instantaneously through pulse jet cleaning and other methods, shaking off the surface dust into the dust hopper, thus completing the dust removal process.

[0023] The gas supply pipe 21 is equipped with a spark catcher 22, which includes a duct, a rotating shaft, a small shaft, a baffle, and rotating guide vanes. A storage bin is provided at the bottom of the spark catcher 22. When high-temperature flue gas containing sparks enters the spark catcher 22, the airflow first passes through a specially constructed airflow guide plate. Due to the principle of aerodynamics, the airflow generates a vortex under the action of the guide plate, forming a swirling flow. Under the action of the swirling flow, sparks and dust in the flue gas collide with the guide vanes, baffle, or pipe wall. During the collision, the sparks are extinguished due to loss of kinetic energy, and the dust is captured and settles into the storage bin, improving the safety of the dust removal equipment.

[0024] The fixture 7 is rotatably connected to a rotating disk 23. A spiral strip 24 is provided on one side of the rotating disk 23. Multiple clamping blocks 25 are equidistantly slidably connected to the outside of the fixture 7. The back side of the clamping blocks 25 is threadedly connected to the spiral strip 24. The fixture 7 is provided with a rotating mechanism that matches the rotating disk 23.

[0025] The rotating mechanism includes a gear ring 14, a gear 15, and a self-locking motor 26. The gear ring 14 is fixedly connected to the other side of the rotating disk 23. The self-locking motor 26 is fixedly installed on the top of the fixture 7. The output end of the self-locking motor 26 passes through the interior of the fixture 7 and is fixedly connected to the gear 15. The outer walls of the gear ring 14 and the gear 15 mesh with each other. The output end of the self-locking motor 26 drives the gear 15 to rotate. The gear 15 meshes with the gear ring 14, and the gear ring 14 is fixed to the rotating disk 23 as one piece. The self-locking motor 26 can drive the rotating disk 23 to rotate inside the fixture 7. The fixture 7 restricts the movement trajectory of the clamping block 25. The clamping block 25 is threadedly engaged with the rotating disk 23 through a spiral strip 24. While the self-locking motor 26 drives the rotating disk 23 to rotate in both directions, it can also drive the clamping block 25 to move linearly back and forth. Adjusting one end of the clamping block 25 to fit against the outer wall of the pipe is used to limit the movement of the pipe.

[0026] A conveying roller 3 is fixedly installed on the left side of the base 1. Guide plates 4 are symmetrically arranged on both sides of the top of the conveying roller 3. The bottom of the pipe is in contact with the top of the base 1. The guide plates 4 can restrict the position of the pipe so that the center of the pipe and the center of the fixture 7 are on the same straight line. The conveying roller 3 rotates in a clockwise direction and can drive the pipe to move towards the fixture 7.

[0027] In this laser cutting machine, the fan 18 draws air from inside the bag filter 17, creating a negative pressure inside the bag filter 17. The bag filter 17 is connected to the second bend 10 via the air supply pipe 21, and the first bend 8 and the second bend 10 are connected to each other via the telescopic pipe 9. The first bend 8 is directly opposite the cutting point of the laser generator 6, while the second bend 10 is directly opposite the cutting pipe. This is used to extract the smoke and dust from the cutting point and the inside of the pipe, and transport it to the inside of the bag filter 17 for processing, separating the dust from the air, which facilitates cleaning of the laser cutting machine.
