[0029] Aluminium foil is contacted with plastic film to form composite film after gluing mechanism 2, composite film is laminated in proper order through laminating mechanism 3, drying mechanism 4.

[0030] The utility model through inlet end's glue pipe 22 and several branch glue pipes 23 are connected to evenly deliver glue to glue head 24, aluminium foil obtains even glue distribution when passing through glue head, subsequently, scraper 25 can be adjusted in position under the action of driving assembly and utilize lug 251 to control the evenness of glue layer thickness and distribution, to improve the adhesion quality of aluminium foil and plastic film;Laminating mechanism 3 is arranged in the middle of base 1, and the composite film is pressed to ensure that the composite film is laminated firmly;Drying mechanism 4 is used to dry and solidify glue after composite is completed, to improve production efficiency and product quality.Due to the integrated design of the above structure, the gluing, laminating and drying processes can be continuously completed in the same device, avoiding the low efficiency and uneven glue layer caused by independent operation of multiple equipment in traditional process, and reducing the risk of loss or pollution of aluminium foil and plastic film during transfer, so as to improve the sealing performance and strength of the package.The utility model guarantees that the device structure is simple and easy to maintain, fully utilizes the synergistic effect of base 1 and each functional mechanism, and significantly improves the production quality and efficiency of aluminium foil bag.

[0031] As an embodiment of the utility model, the top of the gluing frame 21 is provided with a first through hole, the driving assembly comprises a screw rod 26 arranged in the first through hole and a knob 27 arranged at the upper end of the screw rod 26, the lower end of the screw rod 26 is connected with the scraper 25, the first through hole is beneficial to the arrangement and up-down movement of the screw rod 26; the knob 27 is arranged at the upper end of the screw rod 26 and is used for manual or automatic rotation operation, and the scraper 25 is driven to be finely adjusted up and down through the threaded cooperation. Thus, the gap between the scraper 25 and the aluminum foil can be more accurately controlled during the gluing process, and the coating thickness and uniformity of the glue on the surface of the aluminum foil are ensured. The structure is not only convenient to adjust during use, but also can quickly adjust the position of the scraper 25 according to the actual needs of the aluminum foil material, the viscosity of the glue and the like, and effectively improves the gluing precision and adaptability. Through the design of the above-mentioned driving assembly, the problems of inconvenience and unstable gluing caused by repeated disassembly and reliance on fixed height in the traditional device are solved, and the initial glue layer state when the aluminum foil is compounded with the plastic film is further ensured, which lays a good foundation for subsequent lamination and drying.

[0032] As an embodiment of the utility model, the inner wall of the gluing frame 21 is provided with a guide groove 28, both ends of the scraper 25 are provided with sliding blocks, the sliding blocks correspond to the guide grooves 28 one by one, both ends of the side of the scraper 25 close to the glue outlet head 24 are provided with baffles 29, and the guide groove 28 can enable the scraper 25 to stably slide or adjust along the fixed track; the sliding blocks arranged at both ends of the scraper 25 cooperate with the guide grooves 28, which not only ensures the stability of the scraper 25 during operation, but also enables more accurate height adjustment on the gluing area, so that the glue is uniformly spread.

The backing plate 35 is arranged below the compression roller 34 to provide a flat supporting surface for the composite film, so as to ensure the smooth running and close lamination of the composite film during the lamination process. Through the structure, the aluminum foil and the plastic film are synchronously transmitted to the lamination area after the completion of the gluing, and efficient compounding is realized under the pressure of the lifting push rod 32 and the compression roller 34.

When the composite film enters and leaves the lamination area, the tensioning roller 36 maintains appropriate and stable tension, which not only effectively prevents problems such as wrinkles and deviation, but also reduces the quality risks caused by material relaxation or excessive stretching at the connection of multiple processes. Since the tensioning roller 36 cooperates with the compression roller 34, the backing plate 35 and the lifting push rod 32 in the laminating mechanism 3, the aluminum foil can smoothly enter the lamination area together with the plastic film after gluing, and the smooth state is maintained before being conveyed to the drying mechanism 4, so that the bonding strength of the composite film is higher and the appearance is more flat, effectively improving the overall quality and production efficiency of the aluminum foil bag.

After the composite film enters the inlet 42 and is heated inside the box body 41, it is output from the outlet 43, which can effectively shorten the drying period and reduce the defective rate. Compared with the traditional one-way heating or open drying device, the relatively closed heating plate 44 and heating wire 45 structure arranged at the bottom can form a relatively uniform heat field inside, avoiding the problems of temperature difference from top to bottom or insufficient local temperature. Not only the bonding strength and the apparent quality of the aluminum foil bag are improved, but also the overall production efficiency is improved.

In addition, by reasonably setting the air volume and air speed of the fan 471, the temperature and airflow can be further accurately controlled, avoiding the drying dead angle or local overheating phenomenon caused by uneven heat distribution, thereby improving the quality stability of the final product and reducing energy consumption, the structure can also fully utilize the heat energy inside the box 41, reduce heat loss and production energy consumption, and reflect the improvement of the drying process and the consideration of energy-saving effect of the utility model.

[0038] As an embodiment of the utility model, the top of the box 41 is equipped with a first temperature sensor 491, and the heating plate 44 is equipped with a second temperature sensor 492, the first temperature sensor 491 can monitor the temperature environment of the whole inside the box 41 in real time, for judging the distribution and stability of the overall heat field in the drying process, the second temperature sensor 492 can accurately sense the temperature near the heating plate 44 or the heating wire 45 and feedback control, to keep the heat output of the area within the appropriate range. By monitoring the internal environment temperature of the box 41 and the local temperature of the heating plate 44 through the two temperature sensors respectively, the speed of the fan 471 and the heating power can be adjusted more flexibly, avoiding local overheating or uneven drying caused by too high temperature or too large temperature gradient, thereby ensuring the rapid solidification of the glue while considering energy consumption management. The structure not only shortens the drying time and improves the finished product quality of the aluminum foil bag, but also further enhances the automation and safety of the device, so that the utility model has more advantages than the traditional device in temperature accurate control and efficient drying.
