[0002] The invention relates to the technical field of laser cutting devices, and in particular to a laser cutting device used for precision sheet metal machinery manufacturing. Background Art

[0003] Sheet metal is a processing technology for thin metal plates, and laser cutting devices are generally used when cutting thin metal plates. Laser cutting devices use high-power density laser beams to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, evaporated to form holes, and as the beam moves on the material, the holes continuously form a very narrow slit to complete the cutting of the material.

[0004] However, when the traditional laser cutting device is in use, although a collection box is provided inside the machine tool (for collecting the metal sheet and welding slag that falls during cutting), after the laser cutting device cuts the metal sheet, the cut metal sheet will fall into the collection box together with the welding slag, so that the cut metal sheet will be mixed with the welding slag, which makes it very troublesome to take out the metal sheet. In addition, due to the lack of an effective material guiding structure inside the traditional laser cutting device, it is necessary to set up multiple collection boxes inside the machine tool, so that when cleaning the welding slag in the collection box, it is necessary to pour it out one by one, which reduces the convenience of cleaning the welding slag.

[0016] Beneficial Effects

[0017] According to the laser cutting device of each embodiment of the present invention, compared with the traditional laser cutting device, the laser cutting device has a separation mesh plate inside the aggregate frame, so that the cut metal sheet and the welding slag can be automatically separated, so that the cut metal sheet will not be mixed with the welding slag, and when the cut metal sheet is taken out, it is only necessary to first pull the rotating rod upward to pull the sliding block with the plug-in strip out of the rectangular socket, so that the pulled-out plug-in strip can be effectively limited, and then the aggregate frame is manually slid forward to make the aggregate frame slide forward to the upper end surface of the support plate, and then the cut metal sheet on the upper end surface of the separation mesh plate can be taken out. Because the cut metal sheet will not be mixed with the welding slag when taking out the material, it is more convenient to take out the metal sheet.

[0018] In addition, through the setting of the guide hopper, the welding slag falling downward can fall along the mesh holes on the separation screen to the inside of the guide hopper, and then the welding slag can slide into the waste box for collection due to the tilting action of the guide hopper. When the welding slag inside the waste box needs to be cleaned, the waste box only needs to be slid outward from the rectangular opening, and then the welding slag inside the waste box can be poured out and cleaned. During the entire material collecting process, there is no need to set up multiple waste boxes inside the machine tool, so that when cleaning the welding slag in the waste box, only one waste box needs to be poured out, thereby improving the convenience of cleaning the welding slag.

[0019] In addition, through the setting of the linkage mechanism and the knocking mechanism, during the left and right movement of the moving mechanism, a sliding seat on the rear side can move the driving block left and right, so that the chain can rotate clockwise and counterclockwise, thereby driving the first sprocket and the second sprocket to rotate, and then through the first rotating rod, the second rotating rod, the double-groove pulley, the transmission pulley, the two second passive pulleys, and the two rotating shafts to rotate the two cams, so that the other end of the knocking rod can rotate reciprocatingly up and down with the knocking column, so that the lower end of the knocking column can reciprocately knock on the upper end surface of the vibration plate, so that the vibration plate, the aggregate frame and the separation mesh plate are vibrated, so that the welding slag blocked in the mesh holes of the separation mesh plate is cleared, thereby improving the separation effect of the separation mesh plate, and the structure is simple, no manual operation is required, thereby improving the reliability of the separation mesh plate in separating the metal sheet and the welding slag.

[0020] In addition, through the cooperation of the linkage mechanism and the shaking mechanism, during the left and right movement of the moving mechanism, the linkage mechanism can drive the first passive pulley, the transverse rotating shaft, the first bevel gear, the second bevel gear, the vertical rotating shaft and the driving disk to rotate, and then the driving disk can drive one end of the connecting rod to rotate, while the other end of the connecting rod will drive the connecting block and the guide hopper to move back and forth left and right, so that the guide hopper will shake, thereby improving the dropping efficiency of the welding slag inside the guide hopper and avoiding the welding slag from adhering to the guide hopper.

[0049] During the left-right movement of the moving mechanism 3, the two sliding seats 2 will be moved left-right, and the rear sliding seat 2 will move left-right with the driving block 903, and then the driving block 903 will drive the chain 902 to rotate clockwise and counterclockwise, thereby driving the first sprocket 901 and the second sprocket 906 to rotate, thereby driving the double-groove pulley 904 and the transmission pulley 905 to rotate through the first rotating rod and the second rotating rod, and then the double-groove pulley 904 and the transmission pulley 905 respectively rotate with the two second driven pulleys through the belts, so that the two rotating shafts 1001 drive the two cams 1002 to rotate, and the cams 100 When the protrusion rotates to contact the upper end surface of the knocking rod 1003, one end of the knocking rod 1003 is pushed downward, so that the other end of the knocking rod 1003 is tilted upward with the knocking column 1005, and when the protrusion of the cam 1002 is separated from the upper end surface of the knocking rod 1003, one end of the knocking rod 1003 will quickly tilt upward under the action of the spring, and the other end of the knocking rod 1003 will quickly rotate downward with the knocking column 1005, so that the lower end of the knocking column 1005 knocks against the upper end surface of the vibration plate 5, thereby causing the vibration plate 5, the aggregate frame 6 and the separation mesh plate 601 to vibrate, so that the welding slag blocked in the mesh of the separation mesh plate 601 can be cleared.

[0050] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.
