A single cardboard is placed between the driven roller 3 and the active roller 4 manually or through a conveyor. The active roller 4 rotates and under the action of squeezing, the cardboard is squeezed and conveyed forward. The cardboard after preliminary squeezing falls on the top of the lifting plate 10, and the driving unit drives the lifting screw 9 to slowly unload the material, so that the height of each drop is close to the thickness of the cardboard, and the cardboard is preliminarily pressed in this cycle, and an electronic counter is provided on one side of the roller frame 2. When the pressing value reaches a preset value, the active roller 4 stops conveying and pressing, and the driving unit drives the lifting frame 8 to move to the top. Under the action of the travel switch, the No. 2 cylinder 18 drives the limit baffle 19 to move down, and the No. 1 cylinder 13 conveys the folded cardboard to the limit baffle 19 through the limit pull plate 15. The cardboard contacts the limit baffle 19, thereby pressing the paper The position of the plate is adjusted. Under the action of the timer, after the limit baffle 19 briefly contacts the cardboard, the No. 2 cylinder 18 lifts the limit baffle 19, and the No. 1 cylinder 13 drives the limit pull plate 15 to move under the lifting and pressing plate 20, and pushes out the pressed cardboard under the lifting and pressing plate 20. Through the driven roller and the active roller, the extrusion strength and speed of the cardboard can be accurately controlled to ensure the pressing quality of the cardboard; the application of the driving part and the lifting screw rod enables the equipment to adjust the feeding height according to the cardboard of different thicknesses, so as to stack the cardboard, so as to realize automatic stacking. Through the adjustable screw rod lift and the lifting and pressing plate, the pressing height of the entire equipment can be adjusted to make it suitable for production requirements of different specifications; the design of the pushing assembly and the limit baffle plate optimizes the conveying and positioning process of the cardboard, reduces the need for manual adjustment, and improves the overall production fluency.
