[0053] The stacking and unloading mechanism 5 is arranged at the other end of the conveying mechanism 2, and is used to re-stack and unload the packaging boxes 100 filled with absorbent paper in groups.

[0054] The convenience of refilling the packaging box 100 is designed, and the specific structure is as follows: the packaging box material rack 13 includes a plurality of first vertical rods 132 arranged axially along the second material opening 121 and a top cover 131 connected to the top of the first vertical rods 132, and an opening for refilling the packaging box 100 is arranged on the top of the top cover 131, and an avoidance gap is arranged on the side of the opening. The above design allows the packaging box 100 to be refilled in the packaging box material rack 13 by holding the packaging box 100 and placing it between the first vertical rods 132, and the hand can be moved down along the avoidance gap to facilitate the replenishment of a large number of stacked packaging boxes 100.

[0057] The above-mentioned material separation component 14 is designed to separate and tilt the stacked packaging boxes 100 one by one from bottom to top, so as to achieve the simultaneous separation and loading of the stacked packaging boxes and improve the loading efficiency. Figure 3-5 As shown: The initial state of the device before loading is as follows Figure 3As shown in the first usage state, at this time, the first supporting surface 1411 and the third supporting surface 1421 support the packaging box 100 at the bottom to prevent it from falling; then the first telescopic motor 143 drives the first frame 141 to move inward, so that the first supporting surface 1411 is separated from the side wall of the packaging box 100, and the second supporting surface 1412 cooperates with the fourth supporting surface 1422 to abut against the top edge of the packaging box 100 on the upper layer of the bottom packaging box 100, so that the upper packaging box 100 is positioned, and the right end of the bottom packaging box 100 has a tendency to rotate and fall downward. At this time, Figure 4 As shown in the second usage state; thereafter, the second frame body 142 is driven to move in the opposite direction relative to the first frame body 141, so that except for the bottommost packaging box 100, the other upper packaging boxes 100 are pushed by the fourth supporting surface 1422 to move up along the packaging box material rack 13 and separate from the bottommost packaging box 100, and the third supporting surface 1421 separates from the bottommost packaging box 100, so that the supporting and positioning force on it is removed, and its right end sinks and falls on the conveying mechanism 2 at an angle, thereby preventing the packaging box 100 from falling parallel to the conveying mechanism 2, resulting in obvious collision, damage to the quality of the packaging box 100 and excessive production noise. At this time, Figure 5 Use state three. After loading a packaging box 100, the two frames are reset to use state one in reverse order, that is, the second frame 142 is reset, the packaging box 100 in the packaging box material rack 13 is moved down and reset, and supported by its support surface, the first frame 1411 is reset, and the packaging box 100 is supported laterally by the first support surface 1411 to prevent it from sliding down, and then the above operation cycle can be performed to load the packaging boxes 100 one by one.

[0064] Specific as Figure 8 , 9 As shown, when the above-mentioned mechanism is used, the lifting plate 53 is lifted by the fourth telescopic motor 531, so that it passes through the avoidance opening at the end of the conveying mechanism 2, and the packaging box 100 filled with absorbent paper thereon is lifted, and then falls after passing through the limiting plate 511. The packaging box 100 is elastically avoided and supported by the limiting plate 511, and then the above-mentioned operation is repeated. When the set stacking number of packaging boxes 100 is reached, the fifth telescopic motor 543 drives the pushing mechanism 54 to move, so that the comb-shaped pushing plate 542 pushes the assembled packaging box 100 in the corresponding assembly frame 51, so that it moves to the unloading platform 52, waiting for the downward process to be processed and transferred.
