[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Cartons are produced in different sizes according to the needs of use, and are used to package products of different sizes and quantities. In the process of carton production, it is usually necessary to glue the cardboard (that is, the state of the carton when it is unfolded), and glue needs to be applied during gluing. After the glue is applied, the cardboard needs to be pressed to make the glue firmly bonded;
[0003] When pressing the cardboard, glue is usually applied to the adhesive surface of the cardboard first, and then the cardboard is pressed. When pressing the cardboard, the cardboard is usually pressed directly into place at one time by a pressing roller, which causes the glue between the two layers of cardboard to be easily ejected from between the cardboards due to the instantaneous pressure, affecting the quality of the cardboard;

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides Figure 1 - Figure 5 The laminating device for packaging carton paperboard shown in the figure comprises a laminating platform 1 and a gluing roller 2 arranged on the laminating platform 1, wherein the gluing roller 2 is the prior art, and a plurality of glue outlet holes are provided on the surface of the gluing roller 2, which is driven by a driving motor and is not described in detail here. Concave plates 3 are fixedly provided at both ends of the laminating platform 1, and the cross-section of the concave plates 3 is concavely arranged. A plurality of movable laminating modules 4 are arranged on the inner sides of the two concave plates 3, and the laminating modules 4 also comprise a center rod 5 movably arranged on the inner side of the switch concave plate 3, and two limit plates 8 are fixedly provided on the outer side of the center rod 5, and one side of the limit plate 8 slides in contact with the other side of the concave plate 3, and a connecting plate 9 is movably provided on the side of the concave plate 3 corresponding to the limit plate 8, and the connecting plate 9 is fixedly connected to one end of the corresponding limit plate 8, and a laminating roller 6 for laminating paperboards is fixedly provided on the outer side of the center rod 5, and the heights of the plurality of laminating rollers 6 are gradually increased.
[0024] By increasing the number of laminating rollers 6, the paperboards that are pressed once are divided into multiple laminating operations when laminating the paperboards, so as to reduce the single pressure force when laminating the paperboards, prevent the glue from bursting out, and increase the force-bearing time between the two paperboards, so as to prevent the bonding failure caused by the separation of the paperboards;
[0025] A plurality of rectangular grooves 7 are formed through one side of the concave plate 3 , and the end of the center rod 5 moves inside the rectangular groove 7 .
[0026] Two central grooves 11 are provided at the upper end of the pressing table 1. A plurality of fixing rods 12 are fixedly provided on the inner wall of the central groove 11. A telescopic plate 13 is provided in the fixing rod 12 through a spring connection. An inner scraper 14 is fixedly provided at one end of the telescopic plate 13. The inner scraper 14 and the telescopic plate 13 contact the outer side of the cardboard.
[0027] By setting the 14 telescopic plates 13 of the inner scraper, the glue squeezed out from both ends of the cardboard is automatically scraped off when the cardboard is pressed, and the edges of the cardboard are sealed with glue by the multiple 14 telescopic plates 13 of the inner scraper when the cardboard moves, so that the squeezed glue is reused to improve the overall quality of the cardboard.
[0028] Two guide rods 10 are fixedly provided on the inner side of the concave plate 3 , and the guide rods 10 movably pass through the corresponding connecting plates 9 to ensure the movement of the connecting plates 9 .
[0029] An electric cylinder 15 is fixedly provided inside the concave plate 3, and the output end of the electric cylinder 15 is fixedly connected to one end of the corresponding connecting plate 9. Through the setting of the electric cylinder 15, the height of the pressing module 4 can be adjusted as a whole according to the thickness and quantity of the cardboard.
[0030] Working principle: the operator turns on the driving motor to rotate the glue-coating roller 2 to apply glue to the surface of the cardboard being conveyed, so that the cardboard contacts the pressing module 4, so that the first pressing roller 6 presses the cardboard, performs preliminary pressing on the cardboard to prevent the glue from bursting out due to the instantaneous high pressure, and then the cardboard passes through multiple pressing rollers 6. When the pressing rollers 6 press the cardboard, the glue corresponding to the edge of the cardboard is scraped off by the setting of the telescopic plate 13 and the inner scraper 14, and the glue is used for the second time to apply glue to the edge of the cardboard;
[0031] When the thickness of the cardboard changes, the operator controls the electric cylinder 15 so that the electric cylinder 15 drives the connecting plate 9. Through the limitation of the guide rod 10, the connecting plate 9 can only move back and forth in one direction. The connecting plate 9 drives multiple limiting plates 8 to move, and the limiting plates 8 drive the center rod 5 to move. The center rod 5 drives the pressing roller 6 to move, and the initial pressing distance of the pressing roller 6 is adjusted. When the thickness of the cardboard changes, the telescopic plate 13 drives the inner scraper 14 to press against the surface of the cardboard through the spring.
