[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming, etc. Its notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts.

[0003] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated product to quickly melt, vaporize, ablate, or reach ignition point. At the same time, the molten material is blown away by a high-speed airflow coaxial with the beam, thereby cutting the workpiece.

[0004] In the related art, after the sheet metal is cut, a blanking mechanism is needed to blank the cut sheet metal. In the process of cutting and blanking sheet metal, the existing laser cutting machine usually uses manual blanking, but the accuracy of manual blanking is low, and the sheet metal can only be moved to an approximate position. It takes a lot of time to accurately move to the cutting position of the sheet metal, which leads to low cutting efficiency of the sheet metal.

[0005] Therefore, it is necessary to provide a laser cutting machine unloading mechanism to solve the above technical problems. Utility Model Content

[0024] When the device is in use, the sheet metal parts are unloaded by the unloading mechanism 2, and the moving direction of the sheet metal parts is limited by the limiting mechanism 3 during the unloading process to avoid large deviation of the sheet metal parts during the movement.

[0025] The unloading mechanism 2 includes a rotatable threaded sleeve 21 arranged on the inner side of the left side of the unloading box 1, and a screw rod 22 is arranged on the inner horizontal thread of the threaded sleeve 21.

[0028] A groove is provided on the inner side of the discharge box 1 for use with the slide rod 31, which can allow the slide rod 31 to slide up and down. Through the setting of the spring 33, a downward pressure can be applied to the first rotating frame 34, and then the first rotating frame 34 and the first pressure wheel 35 can be used to limit the moving direction of the sheet metal.

[0029] A protection box 25 is provided on the right side of the unloading box 1 , a first gear 26 is rotatably provided on the right side of the inner wall of the protection box 25 , a second gear 27 is provided on the surface of the threaded sleeve 21 , and the second gear 27 meshes with the first gear 26 .

[0030] The inner side of the protection box 25 is provided with a groove which cooperates with the screw rod 22 and can provide the screw rod 22 with left and right movement.

[0031] A motor 28 for driving the first gear 26 to rotate is disposed on the right side of the protection box 25 , and an output end of the motor 28 is fixedly connected to the right side of the first gear 26 .

The moving distance of the push plate 23 can be observed by the setting of the scale rod 24. When the specified cutting distance is reached, the motor 28 is turned off, and the electric telescopic rod 4 is turned on. The electric telescopic rod 4 drives the second rotating frame 5 and the second pressing wheel 6 to move downward, thereby pressing and fixing the position of the sheet metal part to avoid shaking of the rear side of the sheet metal part when cutting the sheet metal part.
