[0050] Cardboard paper has a high stiffness. If the folded surface is small, the adjacent surfaces of the folded surface may become loose after forming due to the tension of the paper. Card boxes are formed from cardboard, with the overlapping surfaces glued together. The two folded surfaces of the card box are not glued. After the box is filled with items, the storage cavity is sealed by a plug and socket: the folded surface is folded over to cover the storage cavity opening, the two adjacent surfaces overlap, and the plug and socket are plugged in. Currently, this packaging method is used manually to package products in workshops. However, after the product is placed in the box, the structure of the manually made box is relatively loose, and some boxes may even open automatically, causing inconvenience in product use.

[0051] In view of this, the present invention provides a method for pre-folding incoming cardboard materials, wherein: Figure 1 This is a schematic diagram of the steps of an embodiment of the method for pre-folding incoming cardboard provided by the present invention. Figure 1 The present invention provides a method for pre-folding incoming cardboard, which specifically includes the following steps:

[0052] S10, providing an entity with sharp corners, aligning and pressing the to-be-folded line of the incoming cardboard material with the edge of the entity;

[0053] S20, folding the cardboard material along the edge to obtain a crease, so that two adjacent surfaces of the crease line are attached to the surface where the solid edge is located;

[0054] S30. After taking out the entity, flatten and fold the two adjacent sides along the indentation line.

[0055] The pre-folding method for cardboard materials provided in the technical solution of the present invention can be used to process cardboard, effectively avoiding the problem in conventional techniques where cardboard, due to its high stiffness, easily unfolds freely, thereby causing the card box structure to become loose or even automatically open. In the present invention, the pre-folding method for cardboard materials can pre-fold the stiff cardboard to form creases. When the cardboard is subsequently stacked into a card box, it can be folded along the existing creases, significantly reducing the possibility of the cardboard unfolding and rebounding. The resulting card box product is more reliable in quality, with a sturdy and non-loose card box structure that is not easily disintegrated, resulting in higher processing and production efficiency.

[0056] The present invention also provides a pre-folding process for a card box, which can be found in Figure 2 , specifically including the following steps:

[0057] S100: The card box includes a paper mold material with a to-be-folded line, wherein the paper mold material is made of cardboard;

[0058] S200, pressing the incoming paper mold material onto an adsorption platform, wherein the adsorption platform has the same size as one surface of the incoming paper mold material;

[0059] S300, providing a rectangular mold to be pressed on a surface of the incoming paper mold material, wherein the rectangular mold can be covered by at least three consecutive surfaces of the incoming paper mold material;

[0060] S400, pushing and folding the three consecutive surfaces of the paper mold material along the rectangular mold to form a shape;

[0061] S500, taking out the mold, and then flattening the space between two adjacent surfaces of the indentation line on the paper mold material so that the two surfaces are relatively attached;

[0062] S600, unfold the incoming cardboard and compact it with a large template.

[0063] It should be noted that the large template here refers to a template with an area larger than the fixed pressure area of ​​the cardboard material. The large template can make the compaction effect of the cardboard material better, make the folds deeper, and facilitate subsequent processing.

[0064] Specifically, taking out the mold in S500 includes: S510, taking out the mold along the vertical direction of the adsorption platform.

[0065] Specifically, the forming of the three consecutive surfaces of the paper mold material by pushing and folding the paper mold material along the rectangular mold in S400 includes: S410, further including a forming cavity, and the adsorption platform can float along the forming cavity;

[0066] The rectangular mold and the paper mold material are sunk into the molding cavity together to mold three consecutive surfaces of the paper mold.

[0067] Specifically, the step of taking out the large template to flatten the incoming paperboard in S600 includes: S610, taking out the large template along a direction parallel to the adsorption platform;

[0068] The large template has a wedge-shaped end portion, and the wedge-shaped end portion is pressed against the incoming paper mold material in a parallel direction to the large template and is slid across the incoming paper mold material to flatten it.

[0069] The following describes the pre-folding method in conjunction with a specific device. This embodiment provides a pre-folding device for a card box. In the technical solution of the present invention, see Figure 3 , shown is the paper model material 500. For details, please see Figure 4 The pre-folding device 1000 of the card box includes a carrier 100, a pre-forming station 200, a flattening and folding station 300 and an unfolding station 400. The carrier 100 is provided with an adsorption platform 110 for adsorbing the paper mold material 500. The pre-forming station 200 is used to form the paper mold material 500. The flattening and folding station 300 is used to fold two adjacent surfaces of the paper mold material. The unfolding station 400 is used to unfold the overlapped paper mold material 500.

[0070] In the technical solution provided by the present invention, the pre-folding device 1000 for the card box includes a carrier 100, a pre-forming station 200, a flattening and folding station 300, and an unfolding station 400. To prevent the manufactured card box from having a loose structure, in this solution, a pre-forming mechanism 210 on the pre-forming station 200, a flattening and folding mechanism 310 on the flattening and folding station 300, and an unfolding mechanism 410 on the flattening station 400 are used to pre-fold creases on the card paper specifically for stacking the card boxes. The unfolding mechanism 410 is then used to unfold the stacked card paper, facilitating subsequent folding and closing into a card box. The solution of the present invention, by pre-folding the creases on the card paper, makes the subsequent stacking of the card paper into a card box more convenient, solving the problem of loose card box packaging structure and the possibility of the packaging box opening automatically, improving the work efficiency of packaging box production, and increasing production benefits.

[0071] As previously mentioned, the card box pre-folding device 1000 includes a carrier 100, a pre-forming station 200, a flattening and folding station 300, and an unfolding station 400. Specifically, the pre-forming station 200 is equipped with a pre-forming mechanism 210, which includes a pre-folding mold 213. The pre-folding mold 213 is arranged to move vertically along the carrier 100. When moving downward, it presses the incoming paper mold 500 onto the carrier 100. The main purpose of this process is to fix the incoming paper mold 500.

[0072] The preforming mechanism 210 includes two pre-folding shovel blocks 211 and a first actuator 212. The two pre-folding shovel blocks 211 have a range of motion that allows them to move toward and away from each other. The first actuator 212 drives the two pre-folding shovel blocks 211. The two pre-folding shovel blocks 211 move toward each other to fold the two sides of the incoming paper mold material 500 in half.

[0073] Furthermore, to make the folding effect better, see Figure 5 Each pre-folding shovel block 211 includes a mounting plate 211a, a first shovel block 211b, and a second shovel block 211c; the first shovel block 211b is fixed on the mounting plate 211a, and the first shovel block 211b has a movable stroke along the up and down directions of the carrier 100, and the second shovel block 211c is located on the opposite sides of the carrier 100, and the two second shovel blocks 211c have a movable stroke that approaches and moves away from each other, and the first driver 212 drives the connection between the mounting plate 211a and the second shovel block 211c.

[0074] Also, see Figure 6To facilitate subsequent processing, the flattening and folding station 300 is equipped with a flattening mechanism 310. The flattening mechanism 310 includes a pressing block 311, which is movable in the vertical direction along the carrier 100. When moving downward, it presses the incoming paper mold material 500 onto the carrier 100. The flattening mechanism 310 is connected to a second driver 312. The pressing block 311 has a vertical movable stroke along the carrier 100 and is used to compress the incoming paper mold material 500 processed by the two pre-folding shovel blocks 211. The second driver 312 drives the pressing block 311.

[0075] Specifically, see Figure 7 An unfolding mechanism 410 is provided on the unfolding station 400. The unfolding mechanism 410 includes a support protrusion 411 and a support driver 412. The support protrusion 411 is movably arranged in the direction of approaching and moving away from the carrier 100, so that when the support protrusion 411 moves in the direction of approaching the carrier 100, the paper mold material 500 is flattened, and the support driver 412 drives the connected support protrusion 411.

[0076] In order to improve the expansion effect of the opening, further, the width of the opening protrusion 411 is gradually narrowed along the expansion direction.

[0077] As mentioned above, the carrier 100 is provided with an adsorption platform 110, which is used to adsorb the paper mold material 500. Figure 3 The adsorption platform 110 includes a supporting plate 111 and an air suction hole 112 . The air suction hole 112 is opened on the supporting plate 111 and is used to adsorb the paper mold material 500 .

[0078] Furthermore, in order to achieve a better positioning effect for the incoming paper mold material 500 , a positioning protrusion 113 may be protrudingly provided on the support carrier 111 , and the positioning protrusion 113 is used to cooperate with the positioning hole of the incoming paper mold material 500 for installation.
