It should be noted that when the cardboards stacked in the middle of the feeding mechanism 2 are successively conveyed to the inside of the base 3, the cutting mechanism 4 is immediately started to cut the cardboards, and the cardboards after cutting will be conveyed to the conveyor closer to the base 3. The conveyor belt 5 is moved to the surface of the conveyor belt 5, and then the conveyor belt 5 transports the cardboard to the side away from the base 3. After the cardboard is transported out of the surface of the conveyor belt 5 away from the base 3, the cardboard is immediately pressed down and fixed by the pressing component 6 and the conveyor belt 5 stops transporting. At this time, three servo motors 701 are started at the same time. Each servo motor 701 drives the corresponding U-shaped rod 702, the movable block 704, and the cleaning rack 705 to rotate 180 degrees. Since the two sets of cleaning components 7 close to the base 3 can be moved to the position of the appropriate cardboard width by the driving component 8 in advance, and each can be respectively moved according to the position of each cut on the four sides of the cardboard The movable block 704 moves to the corresponding position, so when each cleaning rack 705 rotates, the waste in the corresponding incision will be knocked down, and then the downward pressure of the pressing component 6 on the cardboard will be released and the two sets of conveyor belts 5 will be started to transport the cardboard to the surface of the conveyor belt 5 far away from the base 3, and then the cardboard will be pressed down and fixed by the pressing component 6 and the two sets of conveyor belts 5 will be closed, so that the servo motor 701 located between the two sets of conveyor belts 5 drives the corresponding U-shaped rod 702, the movable block 704, and the cleaning rack 705 to rotate another 180 degrees, and the waste in the incision on the side of the cardboard close to the base 3 will be knocked down to avoid the waste being still placed in the cardboard incision.

[0023] like Figure 1As shown, the pressing assembly 6 includes a cross bar 601, the cross bar 601 is fixedly installed inside the base 3, a mounting rod 602 is fixedly installed on the side wall of the cross bar 601, and two hydraulic rods 603 are fixedly installed on the bottom of the mounting rod 602. A pressing plate 604 is fixedly installed at the output end of each hydraulic rod 603. It should be noted that the two hydraulic rods 603 can be started separately to drive the corresponding pressing plates 604 to move downward, and the two pressing plates 604 can be used to press down and fix the cardboards on the surfaces of the two groups of conveyor belts 5.

[0024] like Figures 1 to 3 As shown, the driving component 8 includes a slide groove 801, and the inner bottom surface of the base 3 is provided with a slide groove 801, and a bidirectional screw 802 is movably installed inside the slide groove 801. A servo motor 803 for driving the bidirectional screw 802 to reciprocate is fixedly installed on the side wall of the base 3, and sliders 804 are respectively threadedly connected at both ends of the bidirectional screw 802, and a vertical rod 805 is fixedly installed on the top of each slider 804. Each servo motor 701 is fixedly installed on the top of an adjacent vertical rod 805 or a vertical rod 9. It should be noted that the servo motor 803 drives the bidirectional screw 802 to reciprocate to make the two sliders 804 approach or move away from each other, and the movement of each slider 804 will drive the vertical rod 805 connected to it and the corresponding cleaning component 7 to move synchronously, so that the two groups of cleaning components 7 close to the base 3 are moved to a position with a suitable cardboard width.

[0025] like Figure 1 , Figure 2 As shown, the cleaning component 7 also includes a groove 703, and the inner symmetrical side walls of each U-shaped rod 702 are respectively provided with grooves 703, and the inner hollow area of ​​each groove 703 passes through the end of the corresponding U-shaped rod 702 away from the adjacent servo motor 701, and each movable block 704 is movably installed between two adjacent grooves 703. It should be noted that by moving each movable block 704 inside the corresponding two grooves 703, each cleaning rack 705 can be moved to the corresponding cardboard cut position, and the movable block 704 can be slid out from the corresponding two grooves 703.

[0026] like Figure 1 , Figure 2 As shown, the material cleaning component 7 also includes a bar hole 706. The top of each U-shaped rod 702 is provided with a bar hole 706. The top of each movable block 704 is fixedly installed with a screw rod 707 that passes through the corresponding bar hole 706. Each screw rod 707 is threadedly connected with a nut 708. It should be noted that when each movable block 704 is moved to a suitable position, the corresponding nut 708 is rotated respectively to fix each movable block 704 at the current position.

[0027] like Figure 1 , Figure 2 As shown, the movable block 704 is a cross-shaped structure, and the top surface of each cleaning rack 705 is located on the same horizontal line as the top surfaces of the two conveyor belts 5. It should be noted that since the movable block 704 is a cross-shaped structure, the risk of the movable block 704 shaking and detaching inside the corresponding two grooves 703 can be avoided. The top surface of each cleaning rack 705 is located on the same horizontal line as the top surfaces of the two conveyor belts 5, which can facilitate the transportation of cardboard from the surface of the conveyor belt 5 closer to the base 3 to the surface of the conveyor belt 5 farther from the base 3.

[0028] In summary:

[0029] When the cardboards stacked in the middle of the feeding mechanism 2 are successively conveyed to the inside of the base 3, the cutting mechanism 4 is immediately started to cut the cardboards. After the cutting, the cardboards will be conveyed to the surface of the conveyor belt 5 close to the base 3, and then the conveyor belt 5 will transport the cardboards to the side away from the base 3. After the cardboards are transported out of the surface of the conveyor belt 5 on the side away from the base 3, the cardboards are immediately pressed down and fixed by the pressing component 6 and the conveyor belt 5 stops transporting. At this time, three servo motors 701 are started at the same time. Each servo motor 701 drives the corresponding U-shaped rod 702, the movable block 704, and the cleaning rack 705 to rotate 180 degrees. Since the two sets of cleaning components 7 close to the base 3 can be moved by the driving component 8 in advance, To a position of suitable cardboard width, and each movable block 704 can be moved to a corresponding position according to the position of each incision on the four sides of the cardboard, so when each cleaning rack 705 rotates, the waste in the corresponding incision will be knocked down, and then the pressing component 6 on the cardboard is released and the two sets of conveyor belts 5 are started to transport the cardboard to the surface of the conveyor belt 5 far away from the base 3, and then the cardboard is pressed down and fixed by the pressing component 6 and the two sets of conveyor belts 5 are closed, so that the servo motor 701 located between the two sets of conveyor belts 5 drives the corresponding U-shaped rod 702, the movable block 704, and the cleaning rack 705 to rotate another 180 degrees, and the waste in the incision on one side of the cardboard close to the base 3 is knocked down to avoid the waste still being placed in the cardboard incision.
