Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting machines, and particularly to an exhaust type laser cutting machine. Background Art

[0002] Laser cutting is a high-precision and high-speed thermal cutting method. It uses a laser beam with a high energy density to irradiate the surface of the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point. At the same time, a high-speed air flow coaxial with the beam is used to blow away the molten material, thereby realizing the cutting of the workpiece.

[0003] The patent with the publication number CN215091415U relates to a laser cutting machine with an exhaust device. A gantry is provided on the body of the laser cutting machine. A cross beam is provided in the middle of the gantry. A laser cutting head assembly is installed on the cross beam. An upper dust suction hood is installed above the laser cutting head assembly. The left side of the dust suction device box is connected to a lower dust suction hood through a pipeline. The upper part of the dust suction device box is connected to a water pump through a water supply pipe of a spraying device. The water pump is connected to the bottom of the dust suction device box through a water suction pipe. The right side of the dust suction device box is connected to an air pump through an exhaust pipe. A slag removal port is provided at the bottom in front of the dust suction device box. A spraying device is provided above the interior of the dust suction device box. The beneficial effect of this device is that the upper dust suction hood above the laser cutting head assembly and the lower dust suction hood below the workbench can effectively collect the dust during laser cutting. The spraying device in the dust suction device box plays a role in purifying the dust gas and reducing the dust pollution generated by laser cutting. However, during the process of cutting the sheet material, the steel is prone to shift, which may lead to the problem that the cutting will shift during the cutting of the steel, resulting in the dislocation of the steel cutting. Therefore, an exhaust type laser cutting machine is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an exhaust type laser cutting machine for the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: An exhaust type laser cutting machine includes a support table, a housing is fixedly connected to the top of the support table, and a gantry is arranged on the top of the support table; an exhaust device is arranged on the inner wall of the housing, a slag removal device is arranged on the top of the support table, and an anti-jamming device is arranged at the bottom of the slag removal device; the exhaust device includes a suction fan, a cutter, a suction hood, a hose, a hollow table, a double-shaft motor, a threaded rod, an L-shaped plate, and a fixing plate. The suction fan is fixedly connected to the inner wall of the housing, the cutter is slidably connected to the surface of the gantry, the suction hood is fixedly connected to the right side of the cutter, the hose is fixedly communicated with the front of the suction hood, the hollow table is fixedly connected to the top of the support table, the double-shaft motor is fixedly connected to the top of the support table, the threaded rod is rotatably connected to the output end of the double-shaft motor, the L-shaped plate is threadedly connected to the circumferential surface of the threaded rod, the fixing plate is fixedly connected to the top of the L-shaped plate, the right side of the suction fan is fixedly communicated with the left side of the hose, the bottom of the L-shaped plate is in contact with the top of the hollow table. When cutting steel, the movement of the L-shaped plate drives the movement of the fixing plate, so that the steel to be cut placed on the top of the hollow table can be fixed, reducing the vibration generated during the steel cutting process, thereby improving the accuracy of the steel plate cutting. At the same time, the suction hood can follow the movement of the cutter, and the smoke generated during the laser cutting process can be immediately sucked out, avoiding damage to the laser cutting equipment caused by the particles and impurities generated by the laser cutting.

[0006] Preferably, the slag removal device includes a fixed rod, a support spring, a pressing plate, an inclined plate, a lower pressing strip, an inclined block, and a first elastic telescopic plate. The fixed rod is fixedly connected to the top of the hollow table. The support spring is sleeved on the circumferential surface of the fixed rod. The pressing plate is slidably connected to the circumferential surface of the fixed rod. The inclined plate is fixedly connected to the left side of the fixed plate. The lower pressing strip is fixedly connected to the front part of the inclined plate. The inclined block is fixedly connected to the rear part of the pressing plate. The first elastic telescopic plate is fixedly connected to the top of the hollow table. The slag removal device further includes a cleaning roller, a first transmission wheel, and a rotating roller. The cleaning roller is fixedly connected to the inner wall of the telescopic end of the first elastic telescopic plate. The first transmission wheel is fixedly connected to the central shaft of the cleaning roller. The rotating roller is rotatably connected to the inner wall of the hollow table. The left sides of the lower pressing strip and the inclined block are in contact with each other. The top of the support spring is fixedly connected to the bottom of the pressing plate. When fixing the steel, the downward movement of the inclined block drives the pressing plate to move, so that the top of the steel can be pressed tightly, making the steel plate cut more stably during the cutting process. At the same time, when the steel is placed on the top of the hollow table, the dust on the surface of the steel plate can be scraped off, thus avoiding that more dust on the surface may scatter part of the light beam during the laser cutting process, reducing the effective energy transfer of the laser beam to the workpiece, resulting in a decrease in cutting speed and efficiency. It can also be automatically adjusted according to the thickness of the steel plate through the first elastic telescopic plate. At the same time, the rotating roller rotates, which can reduce the friction between the steel plate and the hollow table, making it easier for the steel plate to be discharged and fed.

[0007] Preferably, the anti-jamming device includes a fixed block, a reciprocating screw rod, a moving bracket, and an arc plate. The fixed block is fixedly connected to the top of the support table. The reciprocating screw rod is rotatably connected to the inner wall of the fixed block. The moving bracket is movably connected to the circumferential surface of the reciprocating screw rod. The arc plate is fixedly connected to the top of the moving bracket. The anti-jamming device further includes a convex block, a second elastic telescopic plate, and a second transmission wheel. The convex block is fixedly connected to the bottom of the hollow table. The second elastic telescopic plate is fixedly connected to the top of the moving bracket. The second transmission wheel is fixedly connected to the circumferential surface of the reciprocating screw rod. The top of the arc plate is in contact with the circumferential surface of the rotating roller. The circumferential surface of the second transmission wheel is in contact with the circumferential surface of the rotating roller. The telescopic end of the second elastic telescopic plate is in contact with the bottom of the convex block. When the steel plate is placed on the top of the hollow table, the movement of the moving bracket drives the arc plate to move, so that the slag generated on the surface of the rotating roller during the cutting process can be cleaned, thus avoiding the rotating roller from being stuck, making it difficult to push out and place the steel plate, and at the same time causing vibration to the hollow table, so that the slag on the surface of the hollow table can be shaken off, and the slag falls into the collection box at the bottom of the support table, which is convenient for workers to clean the device.

[0008] The present invention adopts the above technical solutions and can bring the following beneficial effects: 1. The exhaust type laser cutting machine, through the coordinated operation among the support table, the outer shell, the gantry, the exhaust fan, the cutter, the suction hood, the hose, the hollow table, the double-shaft motor, the threaded rod, the L-shaped plate and the fixing plate, when cutting steel, the movement of the L-shaped plate drives the movement of the fixing plate, so that the steel to be cut placed on the top of the hollow table can be fixed, reducing the vibration generated during the steel cutting process, thereby improving the cutting accuracy of the steel plate. At the same time, the suction hood can move along with the cutter, and the smoke generated during the laser cutting process can be immediately sucked out, avoiding the damage to the laser cutting equipment caused by the particles and impurities generated by laser cutting.

[0009] 2. The exhaust type laser cutting machine, through the coordinated operation among the fixing rod, the support spring, the pressing plate, the inclined plate, the lower pressing strip, the inclined block, the elastic telescopic plate I and the cleaning roller, when fixing the steel, the downward movement of the inclined block drives the movement of the pressing plate, so that the top of the steel can be pressed tightly, enabling the steel plate to be cut more stably during the cutting process. At the same time, when the steel is placed on the top of the hollow table, the dust on the surface of the steel plate can be scraped off, thus avoiding the situation that too much dust on the surface may cause partial scattering of the light beam during laser cutting, reducing the effective energy transfer of the laser beam to the workpiece, resulting in a decrease in cutting speed and efficiency. It can also be automatically adjusted through the elastic telescopic plate I according to the thickness of the steel plate. At the same time, the rotating roller rotates, reducing the friction between the steel plate and the hollow table, making it easier for the steel plate to be discharged and fed.

[0010] 3. The exhaust type laser cutting machine, through the coordinated operation among the fixing block, the reciprocating lead screw, the moving bracket, the arc-shaped plate, the convex block, the elastic telescopic plate II and the transmission wheel II, when the steel plate is placed on the top of the hollow table, the movement of the moving bracket drives the movement of the arc-shaped plate, so that the slag generated on the surface of the rotating roller during the cutting process can be cleaned, thus avoiding the situation that the rotating roller is stuck, making it difficult to push out and place the steel plate, and at the same time causing vibration to the hollow table, so that the slag on the surface of the hollow table can be shaken off, and the slag falls into the collection box at the bottom of the support table, facilitating the cleaning of the device by the worker.

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0014] Please refer to Figures 1 - 8, an embodiment of the present invention is: an exhaust type laser cutting machine, including a support table 1, a housing 2 is fixedly connected to the top of the support table 1, and a gantry 3 is arranged on the top of the support table 1; an exhaust device 4 is arranged on the inner wall of the housing 2, a slag removal device 5 is arranged on the top of the support table 1, and an anti-jamming device 6 is arranged at the bottom of the slag removal device 5; the exhaust device 4 includes a suction fan 41, a cutter 42, a suction hood 43, a hose 44, a hollow table 45, a dual-axis motor 46, a threaded rod 47, an L-shaped plate 48, and a fixing plate 49.

The movement of the cutter 42 drives the suction hood 43 to move, so that the suction hood 43 can follow the cutter 42 to move, and then the smoke generated during the laser cutting process can be immediately sucked out, avoiding damage to the laser cutting equipment caused by the particles and impurities generated by laser cutting. The hose 44 is fixedly connected to the front of the suction hood 43, the hollow table 45 is fixedly connected to the top of the support table 1, the dual-axis motor 46 is fixedly connected to the top of the support table 1, the threaded rod 47 is rotatably connected to the output end of the dual-axis motor 46, the L-shaped plate 48 is threadedly connected to the circumferential surface of the threaded rod 47, the fixing plate 49 is fixedly connected to the top of the L-shaped plate 48, the right side of the suction fan 41 is fixedly connected to the left side of the hose 44, and the bottom of the L-shaped plate 48 is in contact with the top of the hollow table 45. At the same time, when cutting the steel, first place the steel flat on the top of the hollow table 45. At this time, the dual-axis motor 46 is started, and the dual-axis motor 46 drives the L-shaped plate 48 to move to the left. The movement of the L-shaped plate 48 drives the fixing plate 49 to move, so that the steel to be cut placed on the top of the hollow table 45 can be fixed, reducing the vibration generated during the cutting of the steel, and improving the accuracy of the steel plate cutting.

[0015] The slag removal device 5 includes a fixed rod 51, a support spring 52, a pressing plate 53, an inclined plate 54, a lower pressing strip 55, an inclined block 56, and a first elastic telescopic plate 57. The fixed rod 51 is fixedly connected to the top of the hollow platform 45. The support spring 52 is sleeved on the circumferential surface of the fixed rod 51. The pressing plate 53 is slidably connected to the circumferential surface of the fixed rod 51. The inclined plate 54 is fixedly connected to the left side of the fixed plate 49. The lower pressing strip 55 is fixedly connected to the front part of the inclined plate 54. The inclined block 56 is fixedly connected to the rear part of the pressing plate 53. When fixing the steel, the movement of the fixed plate 49 drives the inclined plate 54 to move. The movement of the inclined plate 54 drives the lower pressing strip 55 to move. During the movement of the lower pressing strip 55, it will contact the inclined block 56, and generate a downward extrusion force on the inclined block 56 through the inclined plane, forcing the inclined block 56 to move downward. The downward movement of the inclined block 56 drives the pressing plate 53 to move, so as to press the top of the steel, making the steel plate cut more stably during the cutting process. The first elastic telescopic plate 57 is fixedly connected to the top of the hollow platform 45. The slag removal device 5 further includes a cleaning roller 58, a first transmission wheel 59, and a rotating roller 510. The cleaning roller 58 is fixedly connected to the inner wall of the telescopic end of the first elastic telescopic plate 57. The first transmission wheel 59 is fixedly connected to the central axis of the cleaning roller 58. The rotating roller 510 is rotatably connected to the inner wall of the hollow platform 45. The left sides of the lower pressing strip 55 and the inclined block 56 are in contact with each other. The top of the support spring 52 is fixedly connected to the bottom of the pressing plate 53. At the same time, when the steel is placed on the top of the hollow platform 45, the top of the steel plate will contact the top of the first transmission wheel 59, causing the first transmission wheel 59 to generate frictional force with the top of the steel plate and drive the first transmission wheel 59 to rotate. The rotation of the first transmission wheel 59 drives the cleaning roller 58 to rotate, so as to scrape off the dust on the surface of the steel plate, thereby avoiding too much dust on the surface, which may cause part of the laser beam to be scattered by the dust during the laser cutting process, reducing the effective energy transfer of the laser beam to the workpiece, resulting in a decrease in cutting speed and efficiency. It can also be automatically adjusted through the first elastic telescopic plate 57 according to the thickness of the steel plate. At the same time, when the steel plate is placed on the top of the hollow platform 45, the hollow platform 45 will contact the rotating roller 510 and drive the rotating roller 510 to rotate, thereby reducing the frictional force between the steel plate and the hollow platform 45 and making it easier for the steel plate to feed and discharge materials.

[0016] Working principle: When cutting steel, first place the steel flat on the top of the hollow table 45. At this time, the double-shaft motor 46 starts. The start of the double-shaft motor 46 drives the L-shaped plate 48 to move leftward. The movement of the L-shaped plate 48 drives the fixed plate 49 to move, so that the steel to be cut placed on the top of the hollow table 45 can be fixed, reducing the vibration generated during the cutting of the steel, and thus improving the cutting accuracy of the steel plate. At the same time, after the steel plate is fixed, the gantry 3 will drive the cutter 42 to move according to the pre-set program, so that the steel can be cut into different sizes and shapes. The movement of the cutter 42 drives the suction hood 43 to move, so that the suction hood 43 can move with the cutter 42, and then the smoke generated during the laser cutting can be immediately sucked out, avoiding damage to the laser cutting equipment caused by the particles and impurities generated by the laser cutting.

[0017] When fixing the steel, the movement of the fixed plate 49 drives the inclined plate 54 to move. The movement of the inclined plate 54 drives the pressing strip 55 to move. During the movement of the pressing strip 55, it will contact the inclined block 56 and generate a downward extrusion force on the inclined block 56 through the inclined plane, forcing the inclined block 56 to move downward. The downward movement of the inclined block 56 drives the pressing plate 53 to move, so that the top of the steel can be pressed tightly, enabling the steel plate to be cut more stably during the cutting process. At the same time, when the steel is placed on the top of the hollow table 45, the top of the steel plate will contact the top of the first driving wheel 59, causing the first driving wheel 59 to rotate due to the frictional force with the top of the steel plate. The rotation of the first driving wheel 59 drives the cleaning roller 58 to rotate, so that the dust on the surface of the steel plate can be scraped off, and further avoiding that too much dust on the surface may scatter part of the light beam during the laser cutting process, reducing the effective energy transfer of the laser beam to the workpiece, resulting in a decrease in cutting speed and efficiency. It can also be automatically adjusted through the elastic telescopic plate 57 according to the thickness of the steel plate. At the same time, when the steel plate is placed on the top of the hollow table 45, the hollow table 45 will contact the rotating roller 510 and drive the rotating roller 510 to rotate, thereby reducing the frictional force between the steel plate and the hollow table 45, making it easier for the steel plate to be discharged and fed.

[0018] Please refer to Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, the anti-jamming device 6 includes a fixed block 61, a reciprocating lead screw 62, a moving bracket 63, and an arc-shaped plate 64. The fixed block 61 is fixedly connected to the top of the support table 1. The reciprocating lead screw 62 is rotatably connected to the inner wall of the fixed block 61. The moving bracket 63 is movably connected to the circumferential surface of the reciprocating lead screw 62. The arc-shaped plate 64 is fixedly connected to the top of the moving bracket 63. When the steel plate is placed on the top of the hollow table 45, the rotation of the rotating roller 510 will contact the second transmission wheel 67 and generate frictional force, thereby driving the second transmission wheel 67 to rotate. The rotation of the second transmission wheel 67 drives the reciprocating lead screw 62 to rotate. The rotation of the reciprocating lead screw 62 drives the moving bracket 63 to reciprocate. The movement of the moving bracket 63 drives the arc-shaped plate 64 to move, so that the slag generated on the surface of the rotating roller 510 during the cutting process can be cleaned, and thus the jamming of the rotating roller 510 can be avoided, which may cause the steel plate to be difficult to push out and put in. The anti-jamming device 6 further includes a convex block 65, an elastic telescopic plate two 66, and a second transmission wheel 67. The convex block 65 is fixedly connected to the bottom of the hollow table 45. The elastic telescopic plate two 66 is fixedly connected to the top of the moving bracket 63. The second transmission wheel 67 is fixedly connected to the circumferential surface of the reciprocating lead screw 62. The top of the arc-shaped plate 64 is in contact with the circumferential surface of the rotating roller 510. The circumferential surface of the second transmission wheel 67 is in contact with the circumferential surface of the rotating roller 510. The telescopic end of the elastic telescopic plate two 66 is in contact with the bottom of the convex block 65. At the same time, the movement of the moving bracket 63 drives the elastic telescopic plate two 66 to move. When the elastic telescopic plate two 66 moves and contacts the convex block 65, the convex block 65 will exert an extrusion force on the elastic telescopic plate two 66 to compress the elastic telescopic plate two 66. When the elastic telescopic plate two 66 moves and passes over the convex block 65, the elastic telescopic plate two 66 will no longer be subjected to the extrusion force of the convex block 65 and will reset, and will generate vibration on the hollow table 45, so that the slag on the surface of the hollow table 45 can be shaken off, and the slag will fall into the collection box at the bottom of the support table 1, which is convenient for workers to clean the device.

[0019] Working principle: When the steel plate is placed on the top of the hollow table 45, the rotation of the rotating roller 510 will contact the second driving wheel 67 and generate frictional force, thereby driving the second driving wheel 67 to rotate. The rotation of the second driving wheel 67 drives the reciprocating lead screw 62 to rotate, and the rotation of the reciprocating lead screw 62 drives the moving bracket 63 to move reciprocally. The movement of the moving bracket 63 drives the arc-shaped plate 64 to move, so as to clean the slag generated on the surface of the rotating roller 510 during the cutting process, thereby avoiding the jamming of the rotating roller 510, which may cause the steel plate to be difficult to push out and put in. At the same time, the movement of the moving bracket 63 drives the second elastic telescopic plate 66 to move. During the movement of the second elastic telescopic plate 66, it will contact the convex block 65. When contacting, the convex block 65 will generate a squeezing force on the second elastic telescopic plate 66, causing the second elastic telescopic plate 66 to compress. When the second elastic telescopic plate 66 moves and passes over the convex block 65, the second elastic telescopic plate 66 will no longer be subjected to the squeezing force of the convex block 65 and will reset, and will generate vibration on the hollow table 45, so as to shake off the slag on the surface of the hollow table 45, making the slag fall into the collection box at the bottom of the support table 1, thereby facilitating the cleaning of the device by the worker.

Each component not clearly defined in this embodiment can be implemented by using the prior art.
