Description

TECHNICAL FIELD

[0001] The present application relates to the field of laser cutting equipment, in particular to a five-axis laser cutting equipment for dental mold manufacturing. BACKGROUND

[0002] Through the 3D printing technology, the batch production of the dental mold can be realized without opening the mold. After the production of the dental mold, the laser cutting equipment is used to cut the excess support structure on the surface of the dental mold. The batch of dental molds are transported by the transportation equipment, and then the dental molds are placed on the five-axis machine table by the mechanical hand. The laser is used to cut the excess structure on the surface of the dental mold. After the cutting is completed, the dental mold is taken off from the five-axis machine table by the mechanical hand and placed in the material receiving frame.

[0003] During the laser cutting of the dental mold, the sintering of the dental mold material will produce pungent smoke. If the smoke is randomly dispersed in the factory area, it will seriously affect the air quality in the factory area. Therefore, the suction mechanism is needed to suck and purify the smoke. However, due to the small size of the dental mold, the laser processing space is also relatively small. If the suction port is large, it is far away from the laser cutting, which causes the smoke to be unable to be completely sucked and purified. If the suction port is small, it can be close to the processing part of the laser cutting, but the smoke is easy to escape. Therefore, the commonly used suction mechanism on the market cannot effectively suck and purify the smoke generated by the laser cutting station. SUMMARY

[0025] The odor adsorption unit includes an activated carbon box 31 located above the fixed disc 18, the activated carbon box 31 is fixed in the inside of the sleeve 11, a plurality of air holes 40 are arranged on the upper and lower end surfaces of the sleeve 11, a plurality of activated carbon particles are placed in the inside of the activated carbon box 31, and the outer diameter of the activated carbon particles is much larger than the outer diameter of the air holes 40, a fixed cylinder 32 is fixedly arranged at the center of the activated carbon box 31, and the fixed cylinder 32 is rotatably sleeved on the outer surface of the input end of the gear differential 15, an isolation rotating cylinder 39 is rotatably arranged in the inside of the activated carbon box 31, and the isolation rotating cylinder 39 and the fixed cylinder 32 are coaxially distributed, a stirring part is further arranged in the inside of the isolation rotating cylinder 39, the stirring part is used for stirring the activated carbon particles in the inside of the activated carbon box 31, the activated carbon particles are distributed between the activated carbon box 31 and the isolation rotating cylinder 39, when the gas in the smoke moves upward and passes through the activated carbon box 31, the activated carbon particles in the inside of the activated carbon box 31 can adsorb the odor in the gas, and the gas is purified. Embodiment two: please refer to Figure 9 and Figure 10The embodiment is further illustrated to other embodiments. The dialing component includes a plurality of rotating rods 35 which are circumferentially equidistantly distributed and are rotatably assembled inside the isolation rotating cylinder 39, and the axis of the rotating rod 35 is perpendicular to the axis of the fixed cylinder 32. The inside of the fixed cylinder 32 is provided with a partition layer, and one end of the partition layer is fixedly provided with a second bevel gear 33. The outer surface of the input end of the gear differential 15 is further fixedly sleeved with a sleeve ring 37, and the sleeve ring 37 is distributed in the middle of the partition layer. The end of the rotating rod 35 extending into the inside of the isolation rotating cylinder 39 is rotatably assembled with a connecting rod 38, and the connecting rod 38 is fixed with the sleeve ring 37. The outer surface of each rotating rod 35 is further fixedly sleeved with a third bevel gear 34 which is in meshing connection with the second bevel gear 33. The outer surface of each rotating rod 35 is further fixedly provided with a dialing plate 36. When the input end of the gear differential 15 rotates with the sleeve ring 37, the sleeve ring 37 will rotate the rotating rod 35 and the isolation rotating cylinder 39 in the inside of the activated carbon box 31 through the connecting rod 38, and the rotating rod 35 can also rotate by the meshing of the third bevel gear 34 and the second bevel gear 33. The dialing plate 36 can continuously dial a plurality of activated carbon pellets, so that the activated carbon pellets in the inside of the activated carbon box 31 can uniformly absorb the odor in the smoke.

[0026] The air holes 40 are not distributed on the upper and lower end surfaces of the isolation rotating cylinder 39, because the inside of the isolation rotating cylinder 39 is not placed with activated carbon. When the gas in the smoke passes through the inside of the isolation rotating cylinder 39, the gas odor in the smoke cannot be purified.

[0027] The outer diameter of the third bevel gear 34 is smaller than the outer diameter of the second bevel gear 33. By the difference in outer diameter, when the sleeve ring 37 rotates one circle with the connecting rod 38, the third bevel gear 34 can rotate multiple circles with the rotating rod 35. Working principle: when the operation of the motor 14 drives the gear differential 15 through the two meshing first bevel gears 17, the impeller 16 can quickly rotate, and the impeller 16 can send air upward, that is, the left flared portion 12 inhales, and the right flared portion 12 blows. The gas discharged from the right flared portion 12 can be blown in the form of a wind ring to the smoke generated by laser cutting towards the left flared portion 12 port under the guidance of the conical flow dividing cylinder 13, so that the left flared portion 12 can more fully and effectively absorb the smoke and deliver the smoke upward. When the smoke is upwardly delivered through the sleeve 11, the solid particle impurities in the smoke will adhere to the lower end surface of the filter element 20, that is, the filter element 20 can isolate the solid impurities in the smoke, and the gas continues to be delivered upward. When the gas passes through the air holes 40 and passes through the activated carbon box 31, the activated carbon pellets placed in the inside of the activated carbon box 31 can absorb and purify the odor in the gas, and then the gas is discharged through the right flared portion 12. Through the above-mentioned gas circulation type of smoke filtering and purifying treatment, the smoke can be effectively and fully absorbed.

[0028] When the motor 14 drives the gear differential 15 to operate, the rotating ring 19, the fixed disc 18 and the first rotating shaft 23 will rotate at the same time. When the filter element 20 rotates, the upper edge of the opening part 22 can scrape off the solid impurities adhered to the lower end surface of the filter element 20, until the solid impurities fall into the inner part of the straight cylinder 21. Under the rotation of the first rotating shaft 23 with the helical blade 24, the solid impurities can be transferred to the direction of the magnetic attraction receiving box 26. In this scheme, it is considered that the solid impurities have certain adhesion. In order to ensure that the solid impurities can effectively fall into the inner part of the magnetic attraction receiving box 26, the second rotating shaft 42 can lift the curved rod 29 through the cam 30 and then release it instantly when rotating. Through the elastic reset of the spring 27, the piston disc 41 quickly moves downward to compress the gas, so that when the high-pressure gas flow washes downward, it can impact the solid impurities adhered to the surface of the helical blade 24, so that the solid impurities can quickly fall into the inner part of the magnetic attraction receiving box 26.

[0029] In this scheme, when the input end of the gear differential 15 rotates with the sleeve ring 37, the several rotating rods 35 can revolve while also rotating, so that the poking plate 36 constantly pokes the activated carbon round particles piled in the activated carbon box 31, so that the several activated carbon round particles in the activated carbon box 31 can constantly change positions, so that the several activated carbon round particles can uniformly absorb the peculiar smell components in the gas, so as to avoid that when the activated carbon round particles are replaced later, the activated carbon round particles in the lower layer are in the absorption saturation state, while the activated carbon round particles in the upper middle layer are not yet in the absorption saturation state, so as to improve the utilization efficiency of the activated carbon round particles.
