[0002] In today's life, whether it is food or clothing, cartons are used for packaging or storage. And with the improvement of people's living standards, the demand for the appearance, quality and quantity of cartons is also getting higher and higher. A formed carton first needs to cut the paper into a certain shape, and then go through folding, binding, etc. to be made. At present, in the production process of cartons, for the cutting of paper, a cardboard die-cutting machine is generally used to directly complete the processes of feeding, die-cutting and discharging the cardboard. Using a cardboard die-cutting machine to complete the integrated operation saves time. After the die-cutting machine die-cuts the cardboard, it is necessary to collect the cardboard. At this time, the cardboard is conveyed onto the material receiving table body. A conveying belt is arranged on the material receiving table body. The ends of adjacent cardboard are overlapped. The cardboard in front overlaps on the cardboard behind, so that when the cardboard in front is conveyed to the end of the material receiving table body, it is blocked and stopped. The subsequent cardboard then inserts under the previous cardboard along the movement direction of the cardboard, and finally the cardboard is neatly stacked. Then the operator transports a stack of cardboard to other places for placement.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects. When the cardboard enters the material receiving table body from the die-cutting machine, the overlapping cardboard cannot maintain the overlap well continuously, which ultimately affects the stacking effect of the cardboard and the production efficiency.
