Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Such as Figure 1-2As shown in the figure, a carton pasting and forming mechanism includes a support table 1 that can be lifted and lowered in the vertical direction, and a first pasting roller group 2, a folding knife assembly 3, a second pasting roller group 21, and a pressing plate assembly 4 that are arranged around the lifting table and successively from top to bottom in the vertical direction. There is a first stop station 11 at the first pasting roller group 2 and the folding knife assembly 3, and a second stop station 12 at the second pasting roller group 21 and the pressing plate assembly 4. The support table 1 stops at the first stop station 11 and the second stop station 12. Both the first pasting roller group 2 and the second pasting roller group 21 include two pasting rollers 22 arranged oppositely, and the two pasting rollers 22 can be moved towards or away from each other. The folding knife assembly 3 includes two translation folding knives 31 that can be translated back and forth and four lateral folding knives 32 that can be moved laterally for feeding. The pressing plate assembly 4 includes four pressing plates 41 arranged around the support table 1, and the four pressing plates 41 can all move closer to or away from the center of the support table 1. It also includes four support frames 5 corresponding to the four pressing plates 41. The four pressing plates 41 are all fixedly installed on the corresponding support frames 5. Below the support frames 5, there is an installation table 6. At the positions corresponding to the four support frames 5 on the installation table 6, there are slide rails 61 for the support frames 5 to slide. On two opposite support frames 5, there are fixedly installed guide rails 51. The four lateral folding knives 32 are slidably installed on the guide rails 51 in pairs. The four pasting rollers 22 are all installed on the four support frames 5. Below the installation table 6, there is a linear guide rail structure 7 for lifting the support table 1.

[0020] By adopting the above technical solutions, in the present utility model, the main improvement lies in the improved setting of the structural positions of the first pasting roller group 2, the folding knife assembly 3, the second pasting roller group 21, and the pressing plate assembly 4. Specifically, during operation, the support table 1 moves up and down from top to bottom, and the support table 1 stops at the first stop station 11 and the second stop station 12. The carton will perform the edge folding operation at the first stop station 11, and the carton will perform the pressing operation at the second stop station 12. In this way, the moving stroke of the support table 1 is shortened, and since there is a certain stroke space between the first pasting roller group 2, the folding knife assembly 3, the second pasting roller group 21, and the pressing plate assembly 4, and there is an activity space between each component and the support table 1, thus, it is possible to form different-sized special-shaped cartons without replacing the components of each component, reducing the problem of reduced production efficiency caused by replacing components, and effectively reducing the forming time of the carton.

[0021] Among them, by providing four support frames 5, two of the support frames 5 can move horizontally in the transverse direction through the slide rails 61, and the other two support frames 5 can move horizontally in the longitudinal direction through the slide rails 61. Thus, when one of the support frames 5 moves, the other support frame 5 arranged opposite to this support frame 5 can move towards or away from each other. In this way, the pressing plate 41 has a larger adjustable space, so that when the pressing plates 41 are moved and adjusted, interference will not occur, and it can meet the pressing operation of special-shaped paper boxes of different sizes.

[0022] Moreover, by providing guide rails 51 on two opposite support frames 5, a horizontal movement adjustment of the lateral folding knife 32 can be realized, and through the movement adjustment of the support frame 5 relative to the slide rail 61, the lateral feeding of the lateral folding knife 32 can be realized. Combined with the horizontal movement of the two translational folding knives 31 relative to the support frame 5, the edge folding operation of the paper box can be realized.

[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
