[0002] Water-based laminating adhesive is a method of processing the surface of printed products to improve the glossiness and strength of the printed products and enhance the aesthetic effect. Water-based wet laminating is popular among customers for its high strength, easy recycling and no pollution of the laminated printed products.

[0003] The laminating process is widely used in various packages, ranging from small medicine boxes and craft boxes to large outer packaging boxes and various product packaging. Water-based glue has been widely used in plastic packaging materials and has good environmental protection and adhesion. In the existing water-based glue laminating device, during the glue coating process, the glue is first applied to the surface of the rubber roller and then in contact with the cardboard, so that the glue adheres to the surface of the cardboard, and then the lamination is completed after being bonded with the film.

Figure 1 and Figure 2The fully automatic water-based film coating device for medical packaging boxes includes a body 10, a glue coating assembly 20, two sets of film coating guide assemblies 30, two sets of hydraulic cylinders 40 and a conveying motor 50. The glue coating assembly 20 is installed in the middle section of the body 10, and the conveying motor 50 is installed and fixed on the outer wall of the body 10, and the conveying motor 50 drives the glue coating assembly 20 to coat the paperboard 60 passing through the glue coating assembly 20. The two sets of film coating guide assemblies 30 are symmetrically arranged on the right side of the body 10, and the two sets of hydraulic cylinders 40 are respectively installed and fixed on the opposite sides of the body 10, and each set of hydraulic cylinders 40 drives to adjust the position state of the adjacent film coating guide assemblies 30, so that the two sets of film coating guide assemblies 30 support and guide the film 70 to fit under the paperboard 60 coated with the colloid to complete the film coating process.

[0021] See also Figure 1 , a plurality of supporting rollers 12 are arranged on the inner left side of the body 10, and the plurality of supporting rollers 12 are arranged in an array at equal intervals along the length direction of the body 10, and the ends of each group of supporting rollers 12 are rotatably connected to the body 10. The plurality of supporting rollers 12 are all located below the transmission roller 25 in the gluing assembly 20, and the height of the spacing between the plurality of supporting rollers 12 and the transmission roller 25 is adapted to the thickness of the paperboard 60, so that the supporting rollers 12 can be used to assist in guiding and supporting the paperboard 60 during the transmission process. The inner left side and the inner right side of the body 10 are also formed with support platforms 11 protruding upward. The support platform 11 located on the inner left side of the body 10 supports and fixes the lower part of the gluing assembly 20; the support platform 11 located on the inner right side of the body 10 supports the lower part of the laminated paperboard 60 and the film 70, so that the laminated paperboard 60 can be supported by the support platform 11 below it during the continuous transmission process. A plurality of lower pressing rollers 13 are arranged in an array above the support platform 11 located on the right side of the body 10. The ends of each group of lower pressing rollers 13 are rotatably connected to the body 10. The spacing between the plurality of lower pressing rollers 13 and the support platform 11 located on the right side of the body 10 is adapted to the thickness of the paperboard 60, so that when the laminated paperboard continues to be transmitted on the corresponding support platform, the lower pressing rollers 13 can also be used to assist in closely fitting the paperboard 60 and the film 70.

[0022] See also Figure 3The gluing assembly 20 includes a colloid chamber 21, a gluing roller 22, a gluing auxiliary roller 23 and two transmission rollers 25. The gluing roller 22 and the gluing auxiliary roller 23 are both rotatably connected to the colloid chamber 21, and the gluing auxiliary roller 23 is located directly above the gluing roller 22. A water-based colloid is injected into the inner cavity of the colloid chamber 21, and the top of the outer wall of the gluing roller 22 is exposed above the water-based colloid. When the paperboard 60 is transmitted between the gluing roller 22 and the gluing auxiliary roller 23, the gluing roller 22 and the gluing auxiliary roller 23 can be rotated by friction, and the gluing roller 22 can apply the colloid on the lower surface of the paperboard 60. Excessive colloid can also drip during the transmission of the paperboard 60 to prevent excessive colloid from adhering to its surface. Extension brackets 24 are formed on both the front and rear sides of the top of the colloid chamber 21. The two transmission rollers 25 are symmetrically rotatably connected between the extension brackets 24 located on the front and rear sides of the colloid chamber 21, and the two transmission rollers 25 are separated by the gluing auxiliary roller 23. The output end of the conveying motor 50 is connected to the driving roller 25 near the supporting roller 36 in the film coating guide assembly 30. When the conveying motor 50 drives the driving roller 25 connected thereto to rotate, the driving roller 25 and the supporting roller 36 located therebelow can press the paperboard 60 coated with the colloid and the film 70 located therebelow tightly together and continue to convey to the right.

The middle part of the end seat 32 is rotatably connected to a placement roller 33, and a limiting disk 34 is fixedly connected to the outer wall of one end of the placement roller 33 close to the movable portion 31. When placing the film 70, the rolled film 70 is placed on the two sets of film coating guide assemblies 30, and then the placement rollers 33 in the two sets of film coating guide assemblies 30 move toward each other and extend into the middle of the rolled film, so that the rolled film 70 is supported on the placement rollers 33 of the two sets of film coating guide assemblies 30, and the limiting disks 34 on the two sets of placement rollers 33 are used to limit the front-back position of the film 70. A support roller 36 is arranged above the placement roller 33, and its axial direction is parallel to the placement roller 33. The end of the support roller 36 facing the movable part 31 is rotatably connected thereto, and the support roller 36 is located directly below the transmission roller 25 driven to rotate by the conveying motor 50, and cooperates with the transmission roller 25 to convey the cardboard for lamination. The limiting part 35 is at the same height as the cardboard 60, and the limiting parts 35 in the two sets of lamination guide assemblies 30 limit the front and rear positions of the cardboard 60, so that the two sets of limiting parts 35 can adjust the cardboard 60 to be directly above the film 70, so that the two sets are aligned in the front and rear direction; and the lamination cardboard can also use the limiting parts 35 to wipe the edge of the cardboard during transportation to reduce colloid residue.
