[0014] This invention provides a dual-platform automated laser cutting machine. It has the following advantages:

[0015] (1) In this invention, the material is cooled by the laser cutting machine body in conjunction with the cooling device to prevent the material from overheating during the cutting process, which would cause the material to expand or deform locally, warp or burn. At the same time, the liquid inside the hollow column is used to make the laser cutting machine body move slowly to prevent the laser beam from being processed too quickly, which would result in insufficient processing time between the material and the laser beam, which would prevent the material from being fully melted or vaporized, thus affecting the cutting quality and causing problems such as uneven cutting edges, cracks or burrs. At the same time, the gas is ejected through the connecting pipe by the pressure of the sealing plate, which will cool the laser cutting machine body and prevent the laser cutting machine body from overheating due to continuous use, which may affect the subsequent cutting effect.

[0016] (2) This invention, through the setting of rotating plate, fixed plate and limiting plate, enables the material to be quickly replaced after the laser cutting machine body is cut, without the need for manual replacement, which improves safety and overall work efficiency. At the same time, the trapezoidal plate and long plate material are used to limit the material during the cutting process to prevent the material from shaking up and down during the cutting process, which affects the cutting accuracy. Meanwhile, the position of the material is adjusted by the roller to prevent the position from shifting during the cutting process, which affects the cutting accuracy.

[0017] (3) In this invention, the connecting rod moves to drive the fixed rod to move away from the second processing table, so that the fixed rod pulls the connecting rope to drive the slider to slide. The slider and the rotating plate drive the material to move out of the machine box, so as to realize the quick replacement of materials and prevent the subsequent processing from being affected. At the same time, by adjusting the angle of the adjusting plate, the material falls slowly to prevent the materials from colliding and being damaged due to falling too fast.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-3 One embodiment of the present invention is: a dual-platform automated laser cutting machine, including a chassis 1, a base 2 fixedly installed at the bottom of the chassis 1, a linear motor 3 fixedly installed at the top of the inner wall of the chassis 1, a first processing table 4 fixedly installed at the bottom of the inner wall of the chassis 1, and a second processing table 5 fixedly installed at the bottom of the inner wall of the chassis 1; a protective device, disposed on the inner wall of the chassis 1, the protective device including a support frame 6, a laser cutting machine body 7, a cooling device 8, a hollow column 9, a hollow rod 10, a water inlet 11, a sealing plate 12, a pneumatic cylinder 13, and a connecting pipe 14, which, in conjunction with the cooling device 8, cools the material during the cutting process to prevent overheating of the material during the cutting process. The support frame 6 is fixedly installed on the linear motor 3, and the laser... The cutting machine body 7 is fixedly installed at the bottom of the support frame 6, the cooling device 8 is fixedly installed at the bottom of the support frame 6, the hollow column 9 is fixedly installed on the inner wall of the machine box 1, the hollow rod 10 is fixedly installed on the inner wall of the hollow column 9, the water inlet hole 11 is opened on the surface of the hollow rod 10, the sealing plate 12 is fixedly installed on the surface of the hollow rod 10, the pneumatic cylinder 13 is slidably installed on the inner wall of the hollow column 9, the pneumatic cylinder 13 is fixedly installed at the output end of the linear motor 3, and the connecting pipe 14 is fixedly installed at the bottom of the pneumatic cylinder 13 to prevent the laser cutting machine body 7 from moving too fast, which may result in insufficient processing time between the laser beam and the material, so that the material is not fully melted or vaporized, thereby affecting the cutting quality and causing problems such as uneven cutting edges, cracks or burrs.

[0030] The sealing plate 12 contacts the inner wall of the pneumatic cylinder 13, improving the sealing effect of the pneumatic cylinder 13. The hollow column 9 is filled with liquid, and the cooling device 8 is located on both sides of the laser cutting machine body 7.

[0031] In this embodiment, the linear motor 3 moves, driving the laser cutting machine body 7 to move. The laser cutting machine body 7 performs laser cutting on the material. During the cutting process, a cooling device 8 cools the material to prevent overheating, which could lead to localized expansion, deformation, warping, or burning. The linear motor 3 moving towards the first processing table 4 drives the pneumatic cylinder 13 to move towards the first processing table 4. This movement of the pneumatic cylinder 13 forces the liquid inside the hollow column 9 through the water inlet 11 into the pneumatic cylinder 13. As the pneumatic cylinder 13 moves towards the first processing table 4, it gradually seals the water inlet 11. 1. With a reduced quantity, the speed at which liquid enters the pneumatic cylinder 13 through the water inlet 11 becomes slower. This prevents the laser cutting machine body 7 from moving too fast, which could result in insufficient processing time between the laser beam and the material, preventing the material from fully melting or vaporizing and thus affecting the cutting quality. This could lead to uneven cutting edges, cracks, or burrs. Simultaneously, when the pneumatic cylinder 13 moves towards the first processing table 4, the sealing plate 12 will compress the gas inside the pneumatic cylinder 13. The gas, compressed by the sealing plate 12, will be ejected through the connecting pipe 14. The gas ejected through the connecting pipe 14 will cool down the laser cutting machine body 7, preventing the equipment from overheating due to continuous use, which could affect the subsequent cutting effect.

[0032] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, a pushing device is provided at the bottom of the support frame 6. The pushing device includes a connecting rod 151, a rotating shaft 152, a rotating plate 153, a fixed plate 154, and a limiting plate 155. The connecting rod 151 is fixedly installed on the surface of the support frame 6, the rotating shaft 152 is rotatably installed on the surface of the connecting rod 151, the rotating plate 153 is fixedly installed on the surface of the rotating shaft 152, the fixed plate 154 is fixedly installed on the top of the rotating shaft 152, and the limiting plate 155 is fixedly installed on the connecting rod 151, thereby realizing material replacement and improving overall work efficiency.

[0033] A support base 156 is fixedly installed on the surface of the connecting rod 151. A pulley 157 is rotatably installed on the inner wall of the support base 156. A trapezoidal plate 158 is slidably installed on the top of the second processing table 5. A long plate 159 is fixedly installed on the surface of the trapezoidal plate 158. An elastic telescopic rod 1510 is fixedly installed on the surface of the trapezoidal plate 158. A connecting seat 1511 is fixedly installed on the free end of the elastic telescopic rod 1510. A roller 1512 is fixedly installed on the top of the connecting seat 1511 to prevent the material from shaking up and down during laser cutting, which would affect the cutting accuracy.

[0034] A torsion spring is provided between the rotating shaft 152 and the connecting rod 151. The rotating shaft 152 is reset by the torsion spring. The pulley 157 is in contact with the surface of the trapezoidal plate 158. A spring is provided between the second processing table 5 and the trapezoidal plate 158. The trapezoidal plate 158 is reset by the spring. The side of the trapezoidal plate 158 near the pulley 157 is set as an inclined surface.

[0035] An adjustment device is located at the bottom of the connecting rod 151. The adjustment device includes a fixed rod 161, a rotating shaft 162, a connecting rope 163, a slider 164, a rotating plate 165, a baffle 166, and an adjustment plate 167. The fixed rod 161 is fixedly installed at the bottom of the connecting rod 151. A groove is provided on the inner wall of the second processing table 5. The slider 164 is slidably installed on the inner wall of the groove. The rotating shaft 162 is rotatably installed on the top of the groove. One end of the connecting rope 163 is fixedly installed on the surface of the fixed rod 161, and the other end of the connecting rope 163 is fixedly installed on the surface of the slider 164. The rotating plate 165 is rotatably installed on the top of the slider 164. The baffle 166 is fixedly installed on the circumferential surface of the rotating plate 165. The adjustment plate 167 is rotatably installed on the inner wall of the machine housing 1. The rotating plate 165 pushes the processed parts to move outside the machine housing 1 to prevent them from affecting subsequent processing.

[0036] A rotating rod 168 is fixedly installed at the bottom of the rotating shaft 162, and a gear 169 is fixedly installed at the bottom of the rotating rod 168. A slide groove is opened at the bottom of the housing 1, and a rack 1610 is slidably installed on the inner wall of the slide groove. A connecting push rod 1611 is fixedly installed on the surface of the rack 1610. When the adjusting plate 167 rotates upward, it will contact the falling material, so that the material falls slowly and prevents the materials from colliding and being damaged due to falling too fast.

[0037] A second torsion spring is provided between the rotating plate 165 and the slider 164. The rotating plate 165 is reset by the second torsion spring. A third torsion spring is provided between the adjusting plate 167 and the housing 1. The adjusting plate 167 is reset by the third torsion spring. The baffle 166 is in contact with the surface of the slider 164. The gear 169 meshes with the surface of the rack 1610.

[0038] In this embodiment, during operation, the linear motor 3 drives the support frame 6 to move towards the first processing table 4, which in turn drives the connecting rod 151 to move towards the first processing table 4. The movement of the connecting rod 151 towards the first processing table 4 causes the rotating shaft 152 and the rotating plate 153 to move towards the first processing table 4. The rotating plate 153, moving towards the first processing table 4, comes into contact with the material, causing it to rotate upwards. When the rotating plate 153 disengages from the material, it resets via a torsion spring. Simultaneously, the linear motor 3 drives the rotating plate 153 to move away from the first processing table 4. This movement causes the rotating plate 153 to come into contact with the material. Limited by the fixed plate 154, the rotating plate 153 pushes the material towards the second processing table 5, enabling material replacement and improving overall work efficiency. The movement of the connecting rod 151 away from the first processing table 4... The movable support 156 and pulley 157 move away from the first processing table 4. When the pulley 157 moves away from the first processing table 4, it will contact the trapezoidal plate 158. The pulley 157 will push the trapezoidal plate 158 to move towards the middle of the second processing table 5. When the trapezoidal plate 158 moves towards the middle of the second processing table 5, it will drive the long plate 159 to move towards the middle of the second processing table 5. When the long plate 159 moves towards the middle of the second processing table 5, it will limit the material and prevent the material from shaking up and down during laser cutting, which would affect the cutting accuracy. At the same time, when the trapezoidal plate 158 moves towards the middle of the second processing table 5, it will drive the elastic telescopic rod 1510, the connecting seat 1511 and the roller 1512 to move towards the middle of the second processing table 5. When the roller 1512 moves towards the middle of the second processing table 5, it will contact the material. The position of the material is adjusted by the roller 1512 to prevent the material from shifting, which would cause the cutting position to shift during laser cutting and affect the cutting accuracy.

[0039] The movement of connecting rod 151 towards the first processing table 4 causes fixed rod 161 to move towards the first processing table 4. The movement of fixed rod 161 towards the first processing table 4 causes connecting rope 163 to move towards the first processing table 4. The movement of connecting rope 163 towards the first processing table 4 causes slider 164 and rotating plate 165 to move towards adjusting plate 167. Rotating plate 165 pushes the processed parts out of the machine housing 1 to prevent interference with subsequent processing. Simultaneously, as the material moves from the first processing table 4 to the second processing table 5, the material pushes rotating plate 165 downwards, and rotating plate 165 does not obstruct the material. When processing is complete, slider 164 drives rotating plate 165 to push the material away for recycling. During this pushing process, baffle 166 will move the rotating plate 165. The limit switch facilitates the rotating plate 165 to push the material out of the second processing table 5. At the same time, when the connecting rope 163 is pulled, it will drive the rotating shaft 162 to rotate. The rotation of the rotating shaft 162 will drive the rotating rod 168 to rotate. The rotation of the rotating rod 168 will drive the gear 169 to rotate. The rotation of the gear 169 will drive the rack 1610 to move towards the adjusting plate 167. The movement of the rack 1610 towards the adjusting plate 167 will drive the connecting push rod 1611 to push the adjusting plate 167 to rotate upward. The upward rotation of the adjusting plate 167 will contact the falling material, causing the material to fall slowly and preventing the material from colliding and being damaged due to falling too fast. At the same time, when the connecting rope 163 resets, it will drive the rotating shaft 162 to rotate in the opposite direction. The reverse rotation of the rotating shaft 162 will cause the adjusting plate 167 to lose support and rotate downward, improving work efficiency.
