[0016] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a corrugated cardboard production and cutting device, including a corrugated cardboard cutting body 1, a long circulation conveyor belt 2 is installed in the corrugated cardboard cutting body 1, short circulation conveyor belts 21 are installed on both sides of the long circulation conveyor belt 2, the short circulation conveyor belt 21 protrudes from one side of the long circulation conveyor belt 2, two material discharge positioning push plates 22 are fixedly connected to the outer wall of the long circulation conveyor belt 2, two supporting friction pads 3 are fixedly connected to the side wall of the corrugated cardboard cutting body 1, a connecting pressing plate 31 is provided above the supporting friction pad 3, and an elastic friction pad 32 is fixedly connected to the bottom end of the connecting pressing plate 31.

[0017] In this embodiment: the staff lays the corrugated cardboard on the top of the long circulation conveyor belt 2 and the short circulation conveyor belt 21, and the corrugated cardboard is partially located below the connecting plate 31 and the elastic friction pad 32. The connecting plate 31 and the elastic friction pad 32 move downward under the action of the telescopic rod 33 and the connecting folding rod 34. The connecting plate 31 and the elastic friction pad 32 cooperate with the supporting friction pad 3 to squeeze the corrugated cardboard, and the corrugated cardboard is positioned by the friction force between the supporting friction pad 3 and the elastic friction pad 32 and the corrugated cardboard until the material discharge positioning push plate 22 moves to the upper position. And gradually fit with the edge of the corrugated cardboard. In this process, when the corrugated cardboard is tilted to a certain extent, the part of the corrugated cardboard tilted outward contacts the material discharging positioning push plate 22. The tilted corrugated cardboard will gradually turn over under the action of friction resistance until the corrugated cardboard is flush with the material discharging positioning push plate 22. The corrugated cardboard is pushed to a predetermined position by the material discharging positioning push plate 22, and then the cutting mechanism on the corrugated cardboard cutting body 1 cuts the corrugated cardboard. After the cutting is completed, the long circulation conveyor belt 2 and the short circulation conveyor belt 21 move again to transport the corrugated cardboard to the corrugated cardboard The edge of the cutting machine body 1 is cut, and the staff takes down the corrugated cardboard. The long circulation conveyor belt 2, the short circulation conveyor belt 21 and the material discharging positioning push plate 22 can more conveniently complete the loading, positioning and unloading of the corrugated cardboard, reducing the time for the staff to load, unload and position the corrugated cardboard. With the help of the cooperation between the long circulation conveyor belt 2 and the two short circulation conveyor belts 21, one side of the long circulation conveyor belt 2 can protrude outward to provide space for the staff's limbs, so that the staff can manually hold the corrugated cardboard and place it flat on the long circulation conveyor belt 2, the short circulation conveyor belt 21 and the supporting friction plate. After rubbing the top of the pad 3, the corrugated cardboard will not be partially lifted. When the pressing plate 31 and the elastic friction pad 32 are connected to pressurize and position the corrugated cardboard, creases will not be formed in the suspended position of the corrugated cardboard. The elastic friction pad 32 is a soft material and will not exert excessive pressure on the corrugated cardboard, and will not cause the corrugated cardboard to deform or be damaged. When the device is produced, the long circulation conveyor belt 2 and the short circulation conveyor belt 21 are polished to avoid excessively rough surfaces of the long circulation conveyor belt 2 and the short circulation conveyor belt 21, which may lead to excessive friction between the long circulation conveyor belt 2 and the short circulation conveyor belt 21 and the corrugated cardboard.

[0018] The two supporting friction pads 3 are symmetrically distributed on both sides of the long circulation conveyor belt 2, and the top of the supporting friction pad 3 is flush with the top of the long circulation conveyor belt 2 and the short circulation conveyor belt 21; by setting the supporting friction pad 3, the corrugated cardboard under the connecting pressure plate 31 and the elastic friction pad 32 can be supported.

[0019] An inner support pad 11 is fixedly connected to the inner wall of the corrugated cardboard cutting body 1, and the inner support pad 11 is in contact with the inner walls of the long circulation conveyor belt 2 and the short circulation conveyor belt 21; by providing the inner support pad 11, the long circulation conveyor belt 2 and the short circulation conveyor belt 21 can be supported so that the long circulation conveyor belt 2 and the short circulation conveyor belt 21 can support the corrugated cardboard in a flush manner.

[0020] A driving shaft 23 is installed in the corrugated cardboard cutting body 1, a long driven shaft 24 is installed in the corrugated cardboard cutting body 1, and a short driven shaft 25 is installed in the corrugated cardboard cutting body 1; by setting the driving shaft 23, the long circulation conveyor belt 2 and the short circulation conveyor belt 21 can be driven at the same time, so that the long circulation conveyor belt 2 and the short circulation conveyor belt 21 maintain synchronous linear speed movement to stably convey the corrugated cardboard, the long driven shaft 24 can support the other end of the short circulation conveyor belt 21, and the short driven shaft 25 can support the other end of the long circulation conveyor belt 2.

[0021] A telescopic rod 33 is fixedly connected to the top of the supporting friction pad 3, and a connecting folding rod 34 is fixedly connected to the output shaft of the telescopic rod 33. The connecting folding rod 34 is fixedly connected to the connecting pressure plate 31. By setting the telescopic rod 33, the positions of the connecting pressure plate 31 and the elastic friction pad 32 can be adjusted through the connecting folding rod 34. The extension and retraction of the telescopic rod 33 is controlled by a controller and a control switch. When the corrugated cardboard is discharged, the output shaft of the telescopic rod 33 extends to lift the connecting pressure plate 31 and the elastic friction pad 32 upward.

[0022] The working principle and use process of the utility model are as follows: the staff lays the corrugated cardboard on the top of the long circulation conveyor belt 2 and the short circulation conveyor belt 21, and the corrugated cardboard is partially located below the connecting pressing plate 31 and the elastic friction pad 32. The connecting pressing plate 31 and the elastic friction pad 32 move downward under the action of the telescopic rod 33 and the connecting folding rod 34. The connecting pressing plate 31 and the elastic friction pad 32 cooperate with the supporting friction pad 3 to squeeze the corrugated cardboard, and the corrugated cardboard is positioned by means of the friction between the supporting friction pad 3 and the elastic friction pad 32 and the corrugated cardboard until the material is discharged. The positioning push plate 22 moves to the upper position and gradually fits with the edge of the corrugated cardboard. The material discharging positioning push plate 22 pushes the corrugated cardboard to the predetermined position, and then the cutting mechanism on the corrugated cardboard cutting body 1 cuts the corrugated cardboard. After the cutting is completed, the long circulation conveyor belt 2 and the short circulation conveyor belt 21 move again to convey the corrugated cardboard to the edge position of the corrugated cardboard cutting body 1, and the staff takes the corrugated cardboard off, which makes it more convenient to complete the loading, positioning and unloading of the corrugated cardboard, and reduces the time for the staff to load, unload and position the corrugated cardboard.
