[0014] The following is a detailed description of the specific implementation of the utility model in conjunction with the accompanying drawings:

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "back", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0016] The utility model discloses a paper box forming mechanism, comprising an inner mold 1 for assembling an inner box, a clamping member 6 for clamping a paperboard on the inner mold 1, and a folding assembly 2 for folding the paperboard, wherein the folding assembly 2 comprises a first side folding assembly 21 and a second side folding assembly 22, wherein the first side folding assembly 21 comprises a first folding member 211 and a first driving member 212 for driving the first folding member 211 to rise and fall, and the second side folding assembly 22 comprises a second folding member 221, a second driving member 222 for driving the second folding member 221 to rise and fall, and a third driving member 221 for driving the second folding member 221 to approach or move away from the inner mold 1. Part 223, the first folding part 211 and the second folding part 221 are located on the opposite sides of the inner mold 1 and below the inner mold 1. The first folding part 211 and the second folding part 221 are most preferably folding rollers. In the implementation case of the utility model, it also includes a third folding part 3 for folding the paperboard toward the box mouth and an inner folding socket 4 for inserting the paperboard into the inner box. The inner folding socket 4 is arranged at the tail of the inner mold 1, and the inner mold 1 is also provided with a fourth driving part 5 for driving the inner folding socket 4 to slide. When the inner box is set on the inner mold 1, the third folding part 3 can be moved to the position of the inner box mouth to fold the paperboard toward the inner box mouth.

[0017] By adopting the above technical scheme, when in use, the inner box is put on the inner mold 1, and then the clamping member 6 clamps the cardboard on the inner box, and further the first driving member 212 and the second driving member 222 work to drive the first folding member 211 and the second folding member 221 to rise, and the third driving member 223 further drives the second folding member 221 to extend, so that the cardboard can be adhered to the inner box, and at the same time the third folding member 3 works to fold the cardboard at the box mouth of the inner box so that it is horizontally arranged at the box mouth position, and further the fourth driving member 5 drives the inner folding socket 4 to move, and the cardboard at the box mouth is inserted into the inner box to achieve the folding and adhesion of the cardboard. The first driving member 212, the second driving member 222, the third driving member 223, and the fourth driving member are most preferably cylinders, and of course they can also be motors or electric cylinders.

[0018] The third folding member 3 includes a first plug-in piece 31, a second plug-in piece 32, a third plug-in piece 33 and a fourth plug-in piece 34. The fourth driving member 5 is most preferably provided with two, one of which can drive the inner folding socket 4 to the box opening position of the inner box, and the other can drive the inner folding socket 4 to insert into the inner box. Because the third folding member 3 needs to be withdrawn after folding the cardboard, in order to prevent the cardboard from resetting, the inner folding socket 4 is first moved to the box opening position to prevent it from resetting, so that the cardboard can be folded into the inner box more stably. The first plug-in piece 31 and the second plug-in piece 32 are located on opposite sides of the inner mold 1, the third plug-in piece 33 is located below the inner mold 1, and the fourth plug-in piece 34 is provided on the second folding member 221. The second folding member 221 is most preferably also provided with an extension section extending obliquely downward. 2211, while driving the fourth plug 34 to work, when there is excess part on the side of the cardboard, the extension section 2211 can fold it downward, thereby wrapping the folded side of the first folding piece 211, and also includes a fifth driving member 7 that drives the first plug 31 to move, a sixth driving member 8 that drives the second plug 32 to move, and a seventh driving member 9 that drives the third plug 33 to move. The fourth plug 34 is arranged on the second folding piece 221 and moves synchronously therewith, so that the excess cardboards in four directions can be folded to the box mouth position, and the fourth plug 34 is arranged on the second folding piece 221, which can reduce the setting of one driving member. The fifth driving member 7, the sixth driving member 8, and the seventh driving member 9 are most preferably cylinders, and of course electric cylinders or motors can also be used.

[0019] The inner folding socket 4 is also provided with a support plate 10 for supporting outward so that the folded cardboard adheres to the inner box, and an eighth driving member 20 for driving the support plate 10 to extend and retract, so that the cardboard folded into the inner box can be fully adhered to the inner box, which can prevent the edge from warping and prevent the folded cardboard from detaching from the inner wall of the inner box. The eighth driving member 20 is most preferably a cylinder, and of course it can also be a motor or an electric cylinder.

[0020] The support plates 10 are provided with four groups, one of which is located at the top of the inner folding socket 4, another is located at the bottom of the inner folding socket 4, and the remaining two are arranged on the sides of the inner folding socket 4. The cardboard folded into the inner box in four directions can be supported so that it is fully bonded to the inner box to prevent prying edges, and can also prevent the cardboard from being flipped open by friction when the inner box is removed. When the equipment is assembled on the machine platform, it is most preferred that the inner mold 1 can be adjusted up and down relatively.
