[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Example 1, as Figures 1 to 10 As shown, a laser cutting device for steel plate processing comprises a support leg 1 and a storage box 2 arranged on the side of the support leg 1 for receiving the cut steel plate, the upper part of the support leg 1 is provided with a plurality of racks 3 parallel to each other for supporting the steel plate to be cut, the upper part of the support leg 1 is also provided with a cutting platform 4, and the lower part of the support leg 1 is also provided with a protective frame 5 for receiving slag generated during welding, and a jacking mechanism 7 is provided at the rear between the protective frame 5 and the rack 3. When the cutting platform 4 cuts the steel plate, the slag falls into the protective frame 5 through the gap between the plurality of parallel racks 3, and some of the slag is not cooled in time and adheres to the surface of the rack 3, so the inner side of the support leg 1 is also provided with a slag removal mechanism 8 for removing the slag adhered to the surface of the plurality of racks 3. When in use, the slag particles on the surface of the rack 3 are lifted in cooperation with the jacking mechanism 7 to be removed so that they fall into the inside of the protective frame 5 for collection; Furthermore, a reversing assembly 6 is provided in the middle of the protective frame 5, so that the slag dropped into the inside of the protective frame 5 enters the reversing assembly 6 in an inclined shape through the protective frame 5. When the slag removal mechanism 8 removes the slag attached to the surface of the rack 3 and drives the cut steel plate to perform auxiliary unloading at the same time, the internal structure of the reversing assembly 6 is cooperated to discharge the dropped slag out of the device.

[0022] The cutting platform 4 in this case is composed of a three-axis laser cutting platform consisting of guide rails, gantry beams and columns, ball screws + servo motors, laser cutting heads and control systems in the prior art, which will not be elaborated in detail in this solution.

[0023] In this case, the steel plate to be cut is first hoisted onto the upper part of the rack 3 installed above the support leg 1 by an external mechanical hoist. The steel plate is supported by the teeth on the surface of the rack 3. Then the cutting platform 4 is started, and the internal structure of the cutting platform 4 operates to cut the steel plate. When the high-temperature slag generated during the cutting process contacts the surface of the rack 3, it partially melts and adheres to the surface of the rack 3 before it is completely solidified. At the same time, some spark-like slag falls directly into the interior of the protective frame 5 through the gap between two adjacent racks 3. During the falling process, the slag quickly comes into contact with the air, causing its temperature to drop below the melting point and turn into solid particles. After the steel plate is cut, the internal structure of the jacking mechanism 7 set on both sides of the protective frame 5 is started to push upward. Then, during the rising process of the internal structure of the jacking mechanism 7, its internal structure knocks the internal structure of the slag removal mechanism 8 sliding between the support legs 1 to generate vibration, so that the slag falling through the two adjacent racks is vibrated by the slag removal mechanism 8 and falls off from the inside of the slag removal mechanism 8 to the lower part. At the same time, the jacking mechanism 7 is continuously pushed upward, and then the internal structure of the slag removal mechanism 8 is pushed through the two adjacent racks 3 to the top of the rack 3, and the cut steel plate is removed from the rack 1 at the same time. 3 surface is lifted up and leaves the surface of rack 3, and then the internal structure of slag removal mechanism 8 is started to run. During the operation, its internal structure can roll backward along the surfaces of several racks 3, and at the same time, the slag adhering to the surface of rack 3 is scraped off and falls off. In the process of rolling backward, the internal structure of slag removal mechanism 8 drives the structure under the steel plate to turn over slowly, and synchronously drives the steel plate to turn over on the surface of the internal structure of slag removal mechanism 8, and uses gravity to make the steel plate slide along the inclined surface into the inside of storage box 2, without the need for manual handling of the cut steel plate, thereby greatly reducing manual intervention and reducing labor costs; The residue removed by vibration and scraping naturally falls into the reversing assembly 6 provided in the middle of the protective frame 5, and then the internal components of the reversing assembly 6 are synchronously driven to rotate during the process of the internal structure of the slag removal mechanism 8 scraping the slag backward. During the rotation of the internal components of the reversing assembly 6, the fallen slag can be transported and discharged to the outside of the overall device.

One side of the two racks 3 75 is provided with limit columns 74 installed on both sides of the protective frame 5. The two limiting columns 74 are used to limit the rack three 75 on the same side to prevent the rack three 75 from falling off during the rotation of the driving gear two 76. The output shaft surfaces of the two electric telescopic rods 71 ​​are provided with L-shaped plates 72 that push the rack three 75 to drive the gear two 76 to rotate.

A rotating rod 827 is rotatably provided on one side of several of the fixed blocks 826, which can push the lifting component 85 to flip and assist in unloading the steel plate.

[0030] In the above, first, the support frame 83 is lifted upward to a certain distance by the two electric telescopic rods 71, and at the same time, the lifting assembly 85 is driven by the lifting of the support frame 83 to lift the cut steel plate away from the surface of the rack 3, and at the same time, the two support blocks 821 are driven to rise to a certain height, and a rack 2 822 is slidingly provided above the two support blocks 821, and a gear 1 823 is provided on the surface of the two racks 2 822 that mesh with them, and a rotating shaft 824 is provided between the two gears 1 823. There are thorn discs 825 that can rotate to remove slag from the surfaces of multiple racks 3 at intervals between the rotating shafts 824.
