Detailed Description

The following description of the embodiments of the present application will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The embodiment of the application discloses a water-based laminating device for producing packaging boxes. Referring to fig. 1, the water-based film laminating device for producing the packaging box comprises a machine table 1, a guide roller 2 and a glue coating nozzle 3 arranged on the machine table 1, wherein a pressing accessory 4 for pressing a packaging box paperboard after film lamination is arranged on the machine table 1, a reheating mechanism with a working face pointing to a film on the packaging box paperboard is arranged on the pressing accessory 4, and a heating piece for pressing the packaging box paperboard is arranged on one side, away from the pressing accessory 4, of the coating nozzle 3 on the machine table 1.

The specific heating piece is a heating plate 5 or a heating roller which is arranged parallel to the conveying direction of the package box paperboards, heating wires are arranged in the heating plate 5 or the heating roller, and the surface temperature of the heating plate 5 or the heating roller is more than 70 ℃ and less than 100 ℃.

After setting up like this, when carrying out the tectorial membrane operation of packing carton, packing carton card paper is transmitted at board 1 upper surface, and plastic film is walked around the top of packing carton card paper by being pulled behind the guide roll 2 to press the plastic film to attach on the packing carton card paper under the effect of press fitting 4, glue coating mouth 3 then is pressed the plastic film and is attached on packing carton card paper with aqueous glue before the packing carton card paper, along with the compression molding to the pressure of both attached, can paste the plastic film and press the laminating operation of attaching on the packing carton card paper, realize the packing carton card paper. And because the packing carton card paper is before being smeared glue by glue coating mouth 3, by the heating spare heating for the packing carton card paper is about to be by the temperature of one side of coating glue rise to be close 70 ℃, like this when aqueous glue is coated this side at packing carton card paper, one deck that aqueous glue is close to the packing carton card paper can be adsorbed a part of moisture by packing carton card paper, after plastic film is pressed and is attached on this aqueous glue layer by the bottom stoving, by the stoving of reheat mechanism heating again, can show the time that reduces aqueous glue drying, solidification needs, thereby improve the drying efficiency of aqueous glue on the tectorial membrane packing carton cardboard.

Considering that the aqueous glue is easily solidified into blocks after being dried, the higher temperature on the heating element can interfere the glue in the glue coating nozzle 3 to influence the smooth glue outlet of the coating nozzle 3, therefore, referring to fig. 1, a heat insulation plate 6 is arranged on one side of the heating element, which is close to the coating nozzle 3, so as to reduce the excessive heat transfer on the heating element to the coating nozzle 3.

Meanwhile, referring to fig. 1, two glue guide rods 7 on two sides of the cardboard transmission direction of the split packing box are further installed on the pressing accessory 4, the two glue guide rods 7 are parallel to the upper surface of the machine table 1, the two glue guide rods 7 are arranged in an eight shape, the flaring ends of the two glue guide rods face the coating nozzle 3, optimally, the glue guide rods 7 are arranged on one side, far away from the coating nozzle 3, of the pressing accessory 4, and the pressing accessory 4 is set to be a pressing plate.

After the plastic film is adhered to the packing box paperboard by the pressing accessory 4, redundant water-based glue between the plastic film and the packing box paperboard is extruded to the edge of the packing box paperboard, and then under the guiding action of the two glue guide rods 7 arranged in the shape of the eight, the glue is smoothly guided out to the side of the packing box paperboard, so that the pollution to the packing box paperboard after film coating can be reduced.

And, above-mentioned called reheat mechanism includes the tuyere 8 that sets up along packing carton cardboard width direction, and tuyere 8 is connected with fan 9, and fan 9 air intake or air outlet department are provided with heating device 10, and this heating device 10 sets up to the electric heater strip, and more specifically, tuyere 8 is the slope setting of being reverse in packing carton cardboard transmission direction.

Like this, when the packing carton card paper behind the tectorial membrane passed tuyere 8 below, fan 9 will be blown by the hot air after the heating device 10 to the plastic film of packing carton card paper on, can further heat, dry to the waterborne glue between plastic film and the packing carton card paper to the heating of heating element to the packing carton card paper and tuyere 8 has formed the composite heating stoving to the upper and lower floor of waterborne glue layer to the heating of plastic film, makes the packing carton card paper drying efficiency after the tectorial membrane of this application higher.

The implementation principle of the water-based laminating device for producing the packaging boxes is as follows: when the film coating operation of the packaging box is carried out, the packaging box paperboard is heated by the heating piece before being coated with glue by the glue coating nozzle 3, so that the temperature of one side of the packaging box paperboard, which is to be coated with the glue, is increased to be close to 70 ℃, and when the water-based glue is coated on the side of the packaging box paperboard, a layer of the water-based glue, which is close to the packaging box paperboard, can be adsorbed with a part of water by the packaging box paperboard, and the bottom layer of the water-based glue layer is dried; after the plastic film is pressed on the water-based glue layer dried by the bottom layer, the plastic film is heated and dried by hot air blown by the air nozzle 8, so that the time required for drying and curing the water-based glue can be obviously reduced, and the drying efficiency of the water-based glue on the paperboard of the laminated packaging box is improved.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
