[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-5 A laser cutting machine unloading device includes a unloading assembly 2 and a cutting box 1, wherein a laser cutting machine body 101 is installed on the upper part of the cutting box 1, a unloading assembly 2 is arranged on the lower part of the cutting box 1, and anti-slip mechanisms 3 are arranged on both sides of the cutting box 1;

[0029] The unloading assembly 2 includes a pallet 201 located in the middle of the cutting box 1, and a supporting electric telescopic rod 202 is rotatably connected between the bottom of the pallet 201 and the cutting box 1. A movable groove 205 is opened in the middle of the pallet 201, and a connecting rod 206 is slidably connected inside the movable groove 205. The top of the connecting rod 206 is fixedly connected to a push plate rod 207 slidably connected to the pallet 201, and the push plate of the push plate rod 207 overlaps the surface of the pallet 201, and the bottom end of the push plate rod 207 is fixedly connected to a sliding bin 208 slidably connected to the pallet 201; the initial position of the push plate rod 207 is located at both ends of the movable groove 205, and when moving, it will move from one end of the movable groove 205 to the other end, thereby preventing the material main board from hitting the push plate rod 207 when falling.

[0030] A driving motor 209 is installed inside the sliding bin 208, and a gear 210 is fixedly connected to the output end of the driving motor 209. The gear 210 is meshingly connected to a rack 211, and the rack 211 is fixedly connected to a mounting strip. The top of the mounting strip passes through the sliding bin 208 and is fixedly connected to the bottom of the support plate 201. Since the push plate rod 207 can push the material to slide, there is no need for the support plate 201 to be tilted too much, causing the main board of the material to slide directly.

[0031] Collection frames 203 are installed on both the front and rear sides of the interior of the cutting box 1, and first electric push rods 204 are installed at the four corners of the support plate 201, with the pushing end of the first electric push rods 204 facing upward; the collection frame 203 on the front can collect fallen materials, and the collection frame 203 on the back can collect processed material motherboards, such as metal plates and the like.

[0032] The anti-slip mechanism 3 includes a fixed rod 301 fixedly connected to the cutting box 1, and a rocker 304 rotatably connected to the cutting box 1 is provided below the fixed rod 301, and the rocker 304 is snap-connected to the fixed rod 301; a buckle column 305 is fixedly connected to the upper surface of the middle part of the rocker 304, and the buckle column 305 is snap-connected to a connecting block 302 fixedly connected to the fixed rod 301; a clamping rod 303 is connected through the side of the connecting block 302, one end of the clamping rod 303 is snap-connected to the buckle column 305, and the other end of the clamping rod 303 is fixedly connected to a pull ring, and a reset spring 309 is fixedly connected between the pull ring and the connecting block 302; the reset spring 309 can allow the clamping rod 303 to maintain the snap-connected relationship with the buckle column 305. After the clamping rod 303 is pulled, it will pull the clamping rod 303 to reset, ensuring normal engagement next time.

[0033] A tension spring 306 is rotatably connected between the lower middle part of the rocker arm 304 and the inner wall of the cutting box 1, and a pressure plate 307 is fixedly connected to the bottom end of the rocker arm 304, and a reinforcement knob 308 is threadedly connected to the pressure plate 307; a rubber pad is fixedly connected to the bottom of the reinforcement knob 308, and when the support plate 201 remains horizontal, the height of one end of the tension spring 306 is increased to cooperate with the tension of the tension spring 306, thereby increasing the pressure, and finally increasing the friction between the pressure plate 307 and the material main board to prevent the pressure plate 307 from sliding.

[0034] The working principle of this utility model:

[0035] When the utility model is working, the raw material plate is first placed on the support plate 201, and the first electric push rod 204 is started to lift the raw material plate, and then the pull ring is pulled to make the buckle column 305 disengage from the clamping rod 303, so that the tension spring 306 can pull the rocker 304 to rotate downward, so that the pressure plate 307 is in contact with the surface of the raw material plate;

[0036] At this time, the laser cutting machine 101 is started to perform processing, and the material that falls off during processing will fall onto the supporting plate 201;

[0037] When the processing is completed, the supporting electric telescopic rod 202 is started to tilt the support plate 201 toward the front, and the driving motor 209 is started at the same time, so that the gear 210 and the rack 211 can make the sliding bin 208 drive the connecting rod 206 to slide toward the front in the moving groove 205, so that the push plate rod 207 pushes the fallen materials into the collection frame 203 at the front;

[0038] Then, the first electric push rod 204 is started to lower the raw material plate to fit the support plate 201, and the rocker 304 is lifted to make the buckle column 305 engage with the clamping rod 303, and then the support plate 201 is tilted to the back, and the push plate rod 207 is moved to the back, so as to push the processed raw material plate into the collection frame 203 on the back;

[0039] When the support plate 201 tilts toward the front, the tension spring 306 pulls the pressure plate 307 downward, thereby increasing the friction between the raw material plate and the first electric push rod 204 .

[0040] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
