[0016] 2. This packaging box folding machine sets a block and uses the block to limit the two flip bodies. When the tension spring pulls the two flip bodies towards each other, the flip bodies flip to the maximum extent to fit with the block. When the flip bodies fit with the block, the angle between the flip bodies and the bottom surface of the limit plate is obtuse. Then, when the limit plate drops next time, the angle between the two flip bodies will not be acute, so as to facilitate the flipping of the flip bodies next time. It has a stable use effect and reduces the probability of sticking.

[0017] 3. By setting an elastic member, the elastic member is a hollow sac, and air is inflated into the air storage cavity of the elastic member through an air nozzle. The elastic member has a certain elasticity. After the two flip bodies are flipped to an outward-facing eight state, the elastic member contacts the top surface of the cardboard to achieve another limit on the cardboard, which can reduce the displacement of the cardboard when it is folded to a greater extent.

The two rollers 22 can roll on the top of the packaging box and flatten the packaging box. A sliding channel 30 is opened at the bottom of each flip body 20, and the sliding body 21 slides in the sliding channel 30. A spring is arranged in the sliding channel 30, one free end of the spring is fixedly connected to the flip body 20, and the other end of the spring is fixedly connected to the top surface of the sliding body 21. The spring can push the sliding body 21 toward the package and move;

Both ends of the roller shaft 22 are rotatably connected to the inner wall surface of the sliding body 21 respectively. In this scheme, two reversible flipping bodies 20 are provided, and a sliding body 21 is provided under each flipping body 20. The sliding body 21 is pushed down in the corresponding sliding channel 30 by a spring, and the sliding body 21 drives the roller shaft 22 to contact the top surface of the packaging box. As the limiting plate 12 descends, the two flipping bodies 20 reversely flip, and then the two roller shafts 22 roll on the top surface of the cardboard, simulating a human palm to flatten the cardboard from the middle to both sides, so that the cardboard remains flat and limits the cardboard, which can achieve the purpose of positioning and leveling, and has better practicality.

[0027] like Figure 3 As shown, the sorting component also includes a stopper 23, the bottom surface of the limit plate 12 is fixedly connected with two stops 23, and the stops 23 can limit the turning angle of the flip body 20, and the stopper 23 forms a trapezoidal block structure, the inclined surface of the stopper 23 faces the flip body 20, and the wall surface of the stopper 23 is fixedly connected with a tension spring, and the tension spring is fixedly connected to the flip body 20, and the top of the flip body 20 is rotatably connected to the bottom surface of the limit plate 12.

As the limiting plate 12 descends, the two flip bodies 20 flip in the opposite direction, and then the two rollers 22 roll on the top surface of the cardboard, simulating a human palm to flatten the cardboard from the middle to both sides, and inflate the air storage cavity of the elastic member 24 through the air nozzle. The elastic member 24 has a certain elasticity. After the two flip bodies 20 flip to the outward eight state, the elastic member 24 contacts the top surface of the cardboard to achieve another limit on the cardboard.
