[0002] Cardboard is also called paperboard. It is a thick paper sheet made of various pulps and interwoven with fibers. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Generally, cardboard is defined as paper with a basis weight of more than 250g / m2 and a thickness of more than 0.5mm. Cardboard has a wide range of applications, including but not limited to the packaging industry, household goods, office supplies, handicrafts and electronic products. With the improvement of environmental awareness, the market demand for cardboard as a green and renewable material is also growing.

[0030] The implementation principle of a feeding device for cardboard processing in an embodiment of the present application is as follows: when in use, the cardboard can be placed between two L-shaped frames 11, and the cardboard frame is limited in the L-shaped groove. At this time, the third motor 10 can be started according to the thickness of the cardboard, and the third motor 10 drives the screw 27 to rotate, and the screw 27 drives the slider 19 to move up and down, and the slider 19 drives the baffle 9 to move up and down, and the baffle 9 can move upward into the storage groove 20 to store the excess part. At the same time, when the baffle 9 moves, the part that passes through the L-shaped frame 11 is limited, which can prevent the baffle 9 from shifting when it moves up and down. After adjusting the position, the second motor 12 can be started, and the second motor 12 drives one of the rotating shafts 16 to rotate, and one of the rotating shafts 16 drives the driving wheel 24 to rotate, and the driving wheel 24 drives the belt 18 to rotate, and the belt 18 drives The driven wheel 17 rotates with another rotating shaft 16, thereby driving the belt 18 to move. The movement of the belt 18 drives the mounting block 23 to move. The movement of the mounting block 23 drives the push column 22 to move. The push column 22 pushes the cardboard at the bottom outward, buffers it through the connecting plate 8, and enters the conveyor belt 2 through the inclined plate 7. At the same time, the first motor 14 is started, and the first motor 14 drives the active roller 25 to rotate. The active roller 25 drives the conveyor belt 2 to rotate. The conveyor belt 2 drives the driven roller 26 to rotate, thereby driving the conveyor belt 2 to rotate. The conveyor belt 2 drives the cardboard forward to be transmitted through the cardboard quality detector 5 to detect whether the cardboard is damaged. After detecting damage, the cardboard quality detector 5 transmits the model to the hydraulic cylinder 15. The hydraulic cylinder 15 starts to drive the push plate 4 to push the cardboard to the placement plate 3, thereby removing the defective cardboard.
