Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, in particular to a linked smoke exhaust device for a laser cutting machine. Background Art

[0002] The laser cutting machine works by emitting a high-energy laser beam from the cutting head to irradiate the workpiece, causing the workpiece surface to reach the melting point or boiling point, and then using high-pressure gas to blow away the molten metal debris to complete the cutting of the workpiece. Laser cutting has a small heat-affected zone, no mechanical stress on the incision, and high cutting accuracy. Therefore, it is widely used in industry. The smoke hazards generated by laser cutting machines are easily ignored by operators. The high temperature generated by the laser acts on the processing material to produce a large amount of steam and smoke. These fumes contain a large amount of chemical components, which are also very harmful to the human body. Inhalation of a large amount of dust may even cause respiratory infections, which is not conducive to the health of the operator.

[0003] Publication No. CN 220161508 U discloses a smoke exhaust device for a laser cutting machine, including a cutting machine body, a sliding assembly is provided at the upper end of the cutting machine body, a laser head assembly is provided on the sliding assembly, dust suction pipe assemblies are provided on both sides of the cutting machine body, a filter assembly is connected to the lower end of the dust suction pipe assembly, a pressing assembly is slidably connected to the sliding assembly, and a solenoid valve is provided to control the gas absorption of the connecting pipes at different positions, and the solenoid valve control switch is turned on by longitudinal movement of an L-shaped pressing column. The device has a high degree of automation, cooperates with the filtering device to reduce the emission of toxic gases, and protects the health of the staff. However, the patent still has the following problems in actual use: Although the smoke exhaust device of the laser cutting machine can use the dust suction pipe assembly to absorb the smoke generated by laser cutting, since the pipe mouth of the dust suction pipe assembly is arranged on both sides of the entire device and the cutting position is far away, it is not possible to absorb smoke and dust well. Part of the smoke will drift into the air, thereby polluting the air, and will affect the health of the operator if inhaled. At the same time, the smoke exhaust device of the laser cutting machine does not protect the laser head assembly, resulting in the laser head assembly being exposed to the air for a long time, which has a certain impact on the service life of the laser head assembly.

The specific contents are as follows: 1. By setting up the smoking mechanism, not only can the winding motor be used to drive the winding roller to rotate, so that the winding wire rope can bypass the supporting roller and drive the fixed block and the rotating plate to rotate, but also the first smoking hood and the laser cutting equipment can be rotated out from the inside of the cutting collection box, so as to facilitate the cutting of the laser cutting equipment.

The first translation motor drives the first translation threaded rod to rotate, so that the first translation threaded sleeve and the first translation sliding sleeve drive the longitudinal support frame to move horizontally. At the same time, the longitudinal motor drives the longitudinal threaded rod to rotate, so that the longitudinal threaded sleeve drives the first smoking hood and the laser cutting equipment to move longitudinally, so as to realize the all-round movement of the laser cutting equipment, so as to facilitate cutting in different directions. The bidirectional motor drives the smoking fan to rotate, so that the connecting hose can generate a certain suction force, so as to absorb the smoke generated by the laser cutting, so as to prevent the smoke from drifting into the air, thereby causing air pollution, and at the same time to prevent the operator from inhaling the smoke into the body, thereby causing harm to the body.

When the connecting hose generates suction, the spiral characteristics of the spiral blade can be used to drive the rotating bearing to rotate, thereby further improving the suction of the first smoking hood and improving the efficiency of smoke absorption. The reducer and the cleaning spiral scraper are driven to rotate by the bidirectional motor. The dust and smoke solid particles filtered on the surface of the filter can be cleaned by the cleaning spiral scraper to avoid the dust and solid particles from colliding with the smoking fan, thereby causing damage to the smoking fan. The second translation motor drives the second translation threaded rod to rotate, so that the second translation threaded sleeve and the second sliding sleeve drive the translation limit plate to move horizontally, so that the rotating support rod drives the rotating plate to rotate, which can realize the rotation of the rotating plate. At the same time, the winding motor and the winding wire rope can realize the lifting and moving of the rotating plate, thereby adjusting the height of the first smoking hood and the laser cutting equipment, which is convenient for controlling the depth of laser cutting. When the rotating plate rotates and tilts, the gravity of the counterweight block at the bottom of the rotating smoking hood is used to keep the rotating smoking hood in a horizontal state, so that the rotating smoking hood always covers the top of the cutting part, thereby improving the effect of smoke absorption. 2. By setting up the smoke exhaust mechanism, not only can the purification solution inside the purification box be used to preliminarily absorb harmful substances in the flue gas, but the adsorption carbon plate inside the filter bracket can also be used for secondary treatment of the flue gas, thereby improving the effect of flue gas absorption. At the same time, by rotating the rotating clamping block, the rotating clamping block can be moved from the inside of the filter bracket, so as to facilitate the removal of the adsorption carbon plate from the inside of the filter bracket, and facilitate the rapid cleaning or replacement of the adsorption carbon plate. By setting up multiple adsorption carbon plates, the adsorption carbon plates can be replaced without stopping the machine, thereby improving the working efficiency of the entire linked smoke exhaust device.

[0024] Working principle: Before using the linkage smoke exhaust device of this laser cutting machine, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.12As shown, first, the entire cutting and collecting box 101 is moved to a specified position by moving the base 155, and the winding motor 104 is used to drive the winding roller 105 to rotate, so that the winding wire rope 106 bypasses the supporting roller 109 and drives the fixed block 107 and the rotating plate 110 to rotate, so that the first smoking hood 126 and the laser cutting device 133 can be rotated out from the inside of the cutting and collecting box 101, so as to facilitate the cutting of the laser cutting device 133. When the laser cutting device 133 is not in use, the laser cutting device 133 can be rotated to the inside of the cutting and collecting box 101, so as to protect the laser cutting device 133 and improve the service life of the laser cutting device 133. The first translation motor 117 drives the first translation threaded rod 118 to rotate, so that the first translation threaded sleeve 119 and the first translation sliding sleeve 121 drive The longitudinal support frame 122 moves laterally, and at the same time, the longitudinal motor 123 is used to drive the longitudinal threaded rod 124 to rotate, so that the longitudinal threaded sleeve 125 drives the first smoking hood 126 and the laser cutting equipment 133 to move longitudinally, thereby realizing the all-round movement of the laser cutting equipment 133, which is convenient for cutting in different directions. The second translation motor 146 drives the second translation threaded rod 147 to rotate, so that the second translation threaded sleeve 148 and the second sliding sleeve 150 drive the translation limit plate 151 to move horizontally, and the rotating support rod 152 drives the rotating plate 110 to rotate, which can realize the rotation of the rotating plate 110 and at the same time cooperate with the winding motor 104 and the winding wire rope 106 to realize the lifting and lowering movement of the rotating plate 110, thereby adjusting the height of the first smoking hood 126 and the laser cutting equipment 133, which is convenient for controlling the depth of laser cutting.

[0025] Secondly, by driving the smoking fan 140 to rotate through the bidirectional motor 139, the connecting hose 134 can generate a certain suction force, which can absorb the smoke generated by laser cutting, prevent the smoke from drifting into the air, thereby causing air pollution, and prevent the operator from inhaling the smoke into the body, thereby causing a certain impact on the health of the body. While the connecting hose 134 generates suction, the spiral characteristics of the spiral blade 132 can be utilized to make the spiral blade 132 drive the rotating bearing 131 to rotate, thereby further improving the suction force of the first smoking hood 126 and the efficiency of smoke absorption. The bidirectional motor 139 drives the reducer 141 and the cleaning spiral scraper 142 to rotate. The cleaning spiral scraper 142 can clean the dust and smoke solid particles filtered on the surface of the filter 136 to prevent the dust and solid particles from colliding with the smoking fan 140, thereby causing damage to the smoking fan 140. While the rotating plate 110 rotates and tilts, the gravity of the counterweight block 130 at the bottom of the rotating smoking hood 129 is used to keep the rotating smoking hood 129 in a horizontal state at all times, so that the rotating smoking hood 129 always covers the top of the cutting part, thereby improving the smoke absorption effect.

[0026] Finally, the purification solution inside the purification box 201 is used to preliminarily absorb the harmful substances in the flue gas, and the adsorption carbon plate 206 inside the filter bracket 204 is used to perform secondary treatment on the flue gas, thereby improving the effect of flue gas absorption. At the same time, the rotating clamping block 208 can be moved from the inside of the filter bracket 204 by rotating the rotating clamping block 208, so as to facilitate the removal of the adsorption carbon plate 206 from the inside of the filter bracket 204, and facilitate the rapid cleaning or replacement of the adsorption carbon plate 206. By setting up multiple adsorption carbon plates 206, the adsorption carbon plates 206 can be replaced without stopping the machine, thereby improving the working efficiency of the entire linked smoke exhaust device.
