[0022] In this embodiment, when the punch is lowered, processing is performed through the feed hole 20, and a stopper 11 is provided in the head to resist the waste material during processing to prevent the waste material from sticking or getting stuck in the punch.

[0023] Place the cartons to be drilled on the movable plate 4, fix the position of the cartons by adjusting the push plate 5 and the side baffle 18, start the driving assembly to drive the movable plate 4 to the bottom of the gantry 7, and drill holes in the cartons. After the drilling is completed, drive the movable plate 4 away from the gantry 7 through the first electric slide rail 2 to drill the next group of cartons.

[0024] Furthermore, a first electric slide rail 2 is disposed in each of the two support frames 1 , a slider 3 is slidably disposed on the surface of the first electric slide rail 2 , and the movable plate 4 is fixedly connected to the slider 3 .

[0025] In this embodiment, the slider 3 is driven to slide by the first electric slide rail 2, thereby driving the movable plate 4 to move forward, thereby driving the carton to move on the support frame 1, so as to perform a punching operation on the carton.

[0026] Furthermore, the driving assembly includes a accommodating box 12, which is laterally arranged between the two supporting frames 1 and located at the bottom of the movable plate 4. A motor 13 is arranged on one side of the accommodating box 12, and the output shaft of the motor 13 is fixedly connected to a screw rod 16, and a threaded sleeve 14 is threadedly connected to the surface of the screw rod 16, and a connecting plate 17 is fixedly connected to the surface of the threaded sleeve 14, and the bottom of the push plate 5 is fixedly connected to the connecting plate 17.

[0036] When the carton needs to be placed on the movable plate 4, the side baffles 18 are expanded outward to ensure that the carton can be completely placed on the movable plate 4. After the placement is completed, the side baffles 18 are clamped inward by the second electric slide rails 19 to ensure the stability of the carton during the movement and also ensure stability during the punching process.

[0037] Furthermore, a collecting frame 21 for collecting cartons is provided at the bottom of the movable plate 4 and between the two supporting frames 1 .

[0038] In this embodiment, the discharge hole 20 is located in the middle of the movable plate 4 and is used for the waste to fall after the carton is punched.
