Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machine tools, in particular to a dust suction and cooling type laser cutting machine tool. Background Art

[0002] Laser cutting machine is a processing equipment, which focuses the laser emitted from the laser into a high-power density laser beam through the optical path system, and then irradiates the laser beam to the surface of the workpiece, so that the workpiece reaches the melting point or boiling point and then cuts. However, in the process of laser cutting, there is a more obvious disadvantage that the dust generated is large, and these high-energy laser beams are also accompanied by a lot of heat, so the working environment is very poor, which will have a great impact on the health of the workers. Even if cutting is done in a closed space to isolate the cutting and the workers, it is not applicable to all workpieces. For example, if the cutting piece is large, it may require frequent transfer of the workpiece. Summary of the invention

[0059] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0060] like Figure 1-Figure 15 As shown, a dust suction and cooling laser cutting machine tool comprises a working platform 1, and a movable moving frame 2 is arranged on the working platform 1, and a laser head is arranged on the moving frame 2. At the same time, an air inlet 3 and an air outlet 4 are arranged on both sides of the working platform 1, and the air inlet 3 and the air outlet 4 are connected through a fan 5, and the fan 5 is located below the working platform 1, and a filter box 6 is arranged between the air inlet 3 and the fan 5, and a cooling box 7 is arranged between the air outlet 4 and the fan 5.

[0061] Therefore, during actual use, the fan 5 is used to flow the dust and hot air on the working platform 1 through the air inlet 3 and the filter box 6 to filter and absorb the dust, and the filtered hot air is flowed through the cooling box 7 by the fan 5 and blown out from the air outlet 4 to cool the workpiece and the environment on the working platform 1 and blow the dust and hot air toward the air inlet 3.

[0062] Therefore, the present invention uses the fan 5, filter box 6 and cooling box 7, air inlet 3 and air outlet 4 to remove dust and cool the workpiece and the environment after cutting, and adopts a circulation setting so that the air on the working platform 1 can be reasonably used without relying on air from other places.

[0063] Moreover, as the hot air is drawn away, the cold air, which is heavier, will drop downward, thus playing a preliminary cooling role.

[0064] Secondly, the air inlet member 3 has a built-in partition 33 to divide the interior of the air inlet member 3 into three air inlet areas, and the air outlet member 4 has a built-in partition 43 to divide the interior of the air outlet member 4 into three air outlet areas, and the three air inlet areas of the air inlet member 3 correspond one to one with the three air outlet areas of the air outlet member 4.

[0065] Therefore, in actual use, the present invention can vacuum and cool down the work platform 1 in different areas, and then when processing other areas, vacuum and cool down the processed areas, that is, they can operate synchronously.

[0066] like Figure 3-Figure 6 As shown, the structure of the filter box 6 is as follows: first, a water tank 61 for storing water is arranged at the bottom of the filter box 6, and a water pump 62 connected to the water tank 61 is arranged at the top of the filter box 6, and the connection between the water tank 61 and the water pump 62 is located in the upper half of the water tank 61.

[0067] At the same time, the filter box 6 is built with a partition three 63 to divide the interior of the filter box 6 into three filter areas, and the three filter areas correspond one to one to the three air inlet areas, and the three filter areas are all connected to the water tank 61, and a filter element 1 64 and a filter element 2 65 are arranged in each filter area, and a rotatable nozzle 66 is arranged between the filter element 1 64 and the filter element 2 65, and the nozzle 66 is connected to the water pump 62 and a water outlet is arranged at the bottom of the nozzle 66.

[0068] Therefore, in actual use, the hot air with dust first passes through the filter element 1 64 and is washed by the water sprayed by the nozzle 66, and then passes through the filter element 2 65, so multiple filtrations are achieved, and the water washing also has a certain cooling effect on the hot air. In addition, holes are opened on both sides of the filter box 6 to allow air circulation, and holes are opened on the top of the filter box 6 so that the water pump 62 is connected to the nozzle 66.

[0069] Secondly, water is circulated, so that water utilization is more sufficient. At the same time, since dust will sink to the bottom of the water after being washed by water, the connection between the water tank 61 and the water pump 62 is located in the upper half of the water tank 61, thereby avoiding dust being brought along when the water circulates.

[0070] Furthermore, if the filter element is a simple filter screen, the distance can be adjusted so that the nozzle 66 can play a role in cleaning the filter element.

[0071] At the same time, the rotation structure of the nozzle 66 is: first, the nozzle 66 is Z-shaped and includes a main pipe 661 and side pipes 662 located at both ends of the main pipe 661, and water outlets are provided at the bottom of the main pipe 661 and the side pipe 662. Therefore, when water enters from the main pipe 661 and flows to the side pipe 662, the force exerted by the water on the side pipe drives the nozzle 66 to rotate.

[0072] A water pipe is provided on the top of the nozzle 66, and the water pipe is connected to the water pump 62, and multiple nozzles 66 can be provided on the water pipe to increase the contact between water and air.

[0073] like Figure 3-Figure 6 As shown, other detailed structures of the filter box 6 are as follows: first, the top of the filter box 6 has an opening 67, and the bottoms of the filter element 1 64 and the filter element 2 65 enter from the opening 67 and are located in the filter box 6, and the tops of the filter element 1 64 and the filter element 2 65 are exposed.

[0074] Therefore, in actual use, since the top is exposed, it can be held by hand for easy replacement.

[0075] A guiding and moving structure of bars and grooves is used between the filter element and the partition plate 3 63 and between the filter element and the inner wall of the filter box 6 to achieve guidance and movement.

[0076] At the same time, the filter element 1 64 and the filter element 2 65 are respectively provided with a filter hole 1 and a filter hole 2, and the aperture of the filter hole 1 is larger than the aperture of the filter hole 2.

[0077] Therefore, in actual use, step filtration is achieved by setting different apertures to make the filtration more complete.

[0078] Furthermore, the transverse cross-sections of the filter element 1 64 and the filter element 2 65 are wavy.

[0079] Therefore, in actual use, the wavy cross-section increases the contact area with the air, thereby making the filtration more complete.

[0080] Furthermore, water-absorbing items such as anhydrous calcium chloride can be built into the filter element 65 to absorb moisture in the air and ensure the dryness of the air.

[0081] like Figure 10-13 As shown, the structure of the valve body 8 is as follows: first, the fan 5 and the filter box 6 as well as the air outlet 4 and the fan 5 are connected through a transport pipeline, and the transport pipeline includes a main pipeline and a branch pipeline, wherein the branch pipeline corresponds to the air inlet area or the air outlet area one by one, and a valve body 8 is provided at the connection between the main pipeline and the branch pipeline.

[0082] At the same time, the valve body 8 is built with a partition plate 81 to divide the interior of the valve body 8 into three diversion areas, and a movable baffle 82 is arranged on the valve body 8, and one end of the baffle 82 passes through the valve body 8 and is connected to the electromagnetic component, and the baffle 82 is provided with three diversion holes 821 corresponding to the three diversion areas, and a main port 83 and three diversion ports 84 are respectively opened on both sides of the valve body 8, and a distance is set between the end of the partition plate 81 close to the main port 83 and the inner wall of the valve body 8.

[0083] Therefore, in actual use, when the diverter hole 821 is located in the partition plate 81 or in the side wall of the valve body 8, the main port 83 and the diverter port 84 are not connected, and the baffle 82 is driven to move by the electromagnetic component, so that one of the diverter holes 821 is exposed, thereby connecting the main port 83 and the diverter port 84.

[0084] Therefore, the present invention realizes three disconnections with one valve body by setting the baffle 82, instead of requiring three valve bodies, thereby simplifying the structure and reducing costs.

[0085] The electromagnetic assembly includes a moving iron core, a stationary iron core and a coil, and the moving iron core is connected to the baffle 82. When the coil is energized, a magnetic field is generated between the moving iron core and the stationary iron core, thereby driving the moving iron core to move.

[0086] like Figure 10-13As shown, other detailed structures of the valve body 8 are as follows: first, a heat sink is sleeved on one end of the baffle 82 connected to the electromagnetic assembly, or a heat insulating member is provided between the baffle 82 and the electromagnetic assembly.

[0087] Therefore, in actual use, heat dissipation or heat insulation is provided to prevent heat from being transferred to the electromagnetic component, thereby preventing the heat from affecting the electromagnetic component.

[0088] Secondly, filter screens are provided on the inner wall of the valve body 8 corresponding to the main port 83 and the diversion port 84 , so as to further filter and prevent dust from entering the valve body 8 .

[0089] like Figure 7-Figure 9 As shown, the structure of the cooling box 7 is: first, the cooling box 7 has a cavity 71 built therein, and the top and one side of the cooling box 7 are respectively provided with an opening 2 72 and an opening 3 73 connected to the cavity 71, wherein the opening 2 72 is provided with a cover 74 for placing or taking out a filler 9 from the cavity 71, and the filler 9 is made of a heat-absorbing material.

[0090] At the same time, a movable cover plate 75 is built into the opening three 73 , and a heat-conducting cooling pipe 76 is arranged on one side of the cover plate 75 , and the cover plate 75 and the cooling pipe 76 move synchronously, and the cover plate 75 is provided with an inlet 751 and an outlet 752 corresponding to the cooling pipe 76 .

[0091] Therefore, in actual use, the filler 9 absorbs heat from the air in the cooling pipe 76 and cools it down, and the movable cover plate 75 can drive the cooling pipe 76 out, thereby facilitating the cleaning or replacement of the cooling pipe 76 .

[0092] like Figure 7-Figure 9 As shown, other detailed structures of the cooling box 7 are as follows: first, connecting strips 753 are provided on both sides of the inner wall of the cover plate 75, and a convex strip 711 is provided on the inner wall of the cavity 71, and a connecting groove 754 is provided on the connecting strip 753 corresponding to the convex strip 711.

[0093] Therefore, in actual use, movement is achieved through the convex strips 711 and the connecting grooves 754. In order to make the movement more stable, a convex strip 711 can also be provided at the bottom of the cavity 71, or four connecting strips 753, two on each side and close to the end corners of the cover plate 75.

[0094] At the same time, filter screens are provided on the inner wall of the cover plate 75 corresponding to the inlet 751 and the outlet 752 , so as to further filter and prevent dust from entering the cooling box 7 .

[0095] like Figure 1 and Figure 14-15 As shown, the air inlet member 3 is provided with a sensor 1 on the partition 1 33 , and a sensor 2 and a sensor 3 are provided on both sides of the partition 1 33 .

[0096] Therefore, in actual use, the area where the mobile rack 2 is located can be known by whether the mobile rack 2 passes through the sensor and the order in which it passes through.

[0097] like Figure 14-15 As shown, the structure of the air inlet member 3 is as follows: first, the air inlet member 3 includes a transverse duct 31 and a longitudinal duct 32, and the transverse duct 31 is located on the working platform 1 and is provided with an air inlet 311, and the longitudinal duct 32 is located on one side of the working platform 1 and is provided with an air outlet 321 corresponding to the filter box 6.

[0098] At the same time, the structure of the air outlet member 4 is as follows: first, the air outlet member 4 includes a horizontal pipe 41 and a vertical pipe 42, and the horizontal pipe 41 is located on the working platform 1 and is provided with an air outlet 411, and the vertical pipe 42 is located on one side of the working platform 1 and is provided with an air inlet 421 corresponding to the cooling box 7.

[0099] Therefore, in actual use, the setting of the transverse pipe ensures that the wind on the working platform 1 blows horizontally and can remove dust and cool the air and workpieces on the working platform 1, while the setting of the longitudinal pipe is used to facilitate the connection with the components under the working platform 1, and the longitudinal pipe cooperates with the transverse pipe to achieve connection and coordination with the working platform 1.

[0100] like Figure 1 As shown, the working platform 1 is provided with a groove 11 on one side of the air inlet 1 311 of the air inlet member 3. Therefore, in actual use, the upper surface of the working platform 1 is located in the middle of the air inlet 1 311 by setting the groove 11, thereby ensuring that dust can enter from the air inlet 1 311.

[0101] Moreover, a blowing pipe is provided on one side of the laser head, and the blowing pipe is used to blow the dust to the side of the air inlet 311 close to the air inlet member 3, so that a part of the dust can be blown away before the fan 5 is operated, so that all the dust can be sucked away when the fan 5 is operated later.

[0102] The above shows and describes the basic principle and main features of the present invention and the advantages of the present invention. At the same time, the present invention is not limited by the above embodiments, so without departing from the principle and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
