The working principle or the using method is as follows:
when the laser starts to work, after an operator inputs the attribute of the plate material into the laser device, the laser device controls the corresponding electric push rod 81 to push out forwards according to the attribute of the plate material, at this time, the laser device starts to work, the three-coordinate walking part 2 controls the laser head 3 to slide forwards, the unlocking plate 822 abuts against the sliding pin 731 on the locking device 73 to slide inwards, so that the wire take-up wheel 723 is unlocked, the wire take-up rack 821 is meshed with the wire take-up gear 724 while the wire take-up wheel 723 is unlocked, at this time, the laser head 3 slides forwards continuously to slide forwards, so that the wire take-up gear 724 is driven to rotate, so that the wire draw 726 is tightened, the sliding pressure contact block 715 is driven to slide towards the piston block 711, so that the syringe elastic piece 714 is compressed, so that the elastic force acts on the piston block 711, and the piston block 711 has pressure.
When the laser starts to work, the driving motor 24 drives the whole three-coordinate walking part 2 to slide on the guide rail 12, before the laser head 3 is located above the roller 41, the moving rack 22 on the three-coordinate walking part 2 is meshed with the rolling gear 42 in advance, at the moment, the three-coordinate walking part 2 continues to slide backwards, so that the moving rack 22 drives the rolling gear 42 to rotate, and the rolling gear 42 rotates due to the fact that the lower portion of the rolling gear 42 is meshed with the fixed rack 11, the roller 41 is driven to slide backwards, the roller 41 is separated from the position under the laser head 11, and therefore when the laser cuts a plate, generated slag cannot be sputtered on the roller, and further slag cannot be adhered.
Since the roller 41 is rotatably disposed on the roller shaft 411 and the rolling gear 42 is disposed on the rolling shaft 411, when the moving rack 22 drives the rolling gear 42 on one side to rotate, the whole roller shaft 411 is driven to rotate, so that the rolling gear 42 on the other side also rotates, and thus both ends of the roller 41 move simultaneously, and the roller 41 can move smoothly.
When the three-coordinate traveling unit 2 leaves the area where the roller 41 is located, the guide base 43 is restored to the initial position by the first elastic member 44.
When the moving rack 22 drives the rolling gear 42 to rotate forward, the roller shaft 411 drives the guide seat 43 to move forward, so as to drive the phoenix string airbag 461 to elongate and increase the internal space thereof, at the moment, the internal air pressure is reduced, so that the sliding plug 462 slides inward under the action of the air pressure, so as to communicate the outside with the inside of the phoenix string airbag 461, the external air enters the inside of the phoenix string airbag 461, after the moving rack 22 is disengaged from the rolling gear 42, the guide seat 43 loses the forward acting force, so as to return to the initial position under the action of the first elastic member 44, so that the guide seat 43 moves backward, so as to drive the phoenix string airbag 461 to compress, so as to reduce the internal space thereof, so that the internal air pressure is increased, the sliding plug 462 is pushed to slide outward, so as to block the air inlet, the internal air pressure is continuously increased when the space is continuously reduced, so that the internal air pressure is ejected from the air ejecting port 463 to act on the fixed rack 11, and cleaning dust and tiny particles on the fixed rack 11.
When the moving rack 22 drives the rolling gear 42 to rotate backwards, the roller shaft 411 drives the guide seat 43 to move backwards, so as to drive the phoenix string airbag 461 to compress, so that the internal space thereof is reduced, therefore, the internal air pressure is increased, the sliding plug 462 is pushed to slide outwards to block the air inlet, the internal air pressure is continuously increased when the space is continuously reduced, so that the internal air pressure is sprayed out from the air spraying port 463 to act on the fixed rack 11 to clean dust and tiny particles on the fixed rack 11, after the moving rack 22 is disengaged from the rolling gear 42, the backward acting force of the guide seat 43 is lost, so that the guide seat returns to the initial position under the action of the first elastic element 44, the guide seat 43 is driven to move forwards to drive the phoenix string airbag 461 to elongate, so that the internal space thereof is increased, at the moment, the internal air pressure is reduced, so that the sliding plug 462 slides inwards under the action of the air pressure to communicate the outside with the interior of the phoenix string airbag 461, the outside air enters the inside of the phoenix balloon 461.
When the laser starts to set the tool, because the laser does not work, no heat is generated, and the bimetallic strip 63 deforms, so that the double-layer transparent shielding piece 64 is transparent, and the sight of an operator can well see through the double-layer transparent shielding piece 64 to observe the position of the laser head.
When the laser equipment starts to work, the laser head 3 descends by a certain height, at the moment, the rolling steel balls 66 on the outer cover frame 61 at the bottom of the laser head are abutted against the plate, no gap exists between the plate and the plate, the laser cutting plate is actually focused on a light spot, and then the plate on the spot is melted, so a large amount of heat can be generated, at the moment, the rolling steel balls 66 are abutted against the periphery of the melted plate, so that the heat on the plate can be well collected and transferred to the outer cover frame 61, the bimetallic strip 63 in the plate is deformed, the liquid storage bag 62 is pressed and contacted, the liquid storage bag 62 is deformed, the space in the liquid storage bag is reduced, the solution with low light transmittance in the liquid storage bag is extruded into a gap in the middle of the double-layer transparent shielding piece 64, the double-layer transparent shielding piece 64 becomes opaque, and strong light generated by internal laser is shielded and cannot penetrate through the double-layer transparent shielding piece 64.
Since the bimetal 63 deforms and presses and contacts the liquid storage bag 62 and the pressure contact rod 764, the blocking slider 761 slides inwards, the through hole 765 is communicated with the injection channel 751, at the moment, since the piston block 711 is pressed, after the injection channel 751 is communicated, the dye in the needle cylinder 712 enters the injection port 75 through the dye pipe 74, the dye acts on the plate material through the injection channel 751, and since the injection port 75 is provided with a plurality of groups, the dye can be sprayed on the cut plate and the retained plate no matter how the laser head 3 travels, and the corresponding colors of different plate materials are different, so that the plate material of the same material can be sprayed with the same color no matter the plate is a waste plate or a required plate, and the material property of the plate material can be identified according to the color.
After the laser operation is completed, the laser head is lifted upwards, the rolling steel balls 66 are separated from the surface of the plate, the heat on the plate is not conducted to the rolling steel balls 66, so that the temperature of the outer cover frame 61 is rapidly reduced, the bimetallic strip 63 is restored to the initial state, the pressure contact between the bimetallic strip 63 and the liquid storage bag 62 is eliminated, the liquid storage bag 62 is restored to the initial state, the internal space is also restored to the initial state, the solution with low light transmittance in the gap between the double-layer transparent shielding piece 64 returns to the liquid storage bag 62, and the double-layer transparent shielding piece 64 is restored to the transparent state again.
At this time, the bimetal 63 is restored to the initial state, the press contact on the press contact rod 764 disappears, the blocking slider 761 is pushed forward under the action of the blocking elastic member 762, and therefore, the spraying channel 751 is misaligned with the through hole 765, so that the spraying channel 751 is no longer through, the dye is no longer sprayed, and the color spraying of the plate is realized only when the laser is used for cutting.
