[0027] As the improvement of the above scheme, multiple electric push rod one 33, push block 34 and roller bar 35 are arranged in the inside of upper roller plate 31 with interval, the middle two groups of electric push rod one 33, push block 34 and roller bar 35 are distributed in V shape, the roller bar 35 distributed in V shape can roller the high barrier film 6 after compounding from different directions, and then can sufficiently level the glue solution in barrier film, so that the glue solution is coated more evenly;

[0028] In the embodiment, the film feeding mechanism 2 includes a first film feeding roller 21, a second film feeding roller 22 and a pressing roller 23. The first film feeding roller 21 and the second film feeding roller 22 are arranged at the inner side of the mounting bracket 1A end with interval. The gluing device 5 is located between the first film feeding roller 21 and the second film feeding roller 22. When the film of the first film feeding roller 21 passes through the gluing device 5, the gluing device 5 will coat glue on the film. The side, away from the first film feeding roller 21, of the second film feeding roller 22 is provided with the pressing roller 23. The pressing roller 23 is arranged vertically and mirror image. The pressing roller 23 can press the high barrier film 6 after gluing.

[0029] The implementation principle of the first embodiment is as follows: when the composite device is used to compound the high barrier film, the first roller and the second roller in the film feeding mechanism 2 send the base film to the roller mechanism 3 after gluing by the gluing device 5. At this time, the multiple roller bars 35 in the roller mechanism 3 can roller and level the high barrier film 6 after compounding. The roller bars 35 distributed in V shape cooperate with the roller bars 35 distributed horizontally to level the high barrier film 6 from multiple directions, so that the glue solution in the high barrier film 6 is coated more evenly. Thus, the glue solution unevenness can be prevented from causing bubbles in the high barrier film 6, which affects the quality of the high barrier film after compounding.

[0030] In the above embodiment, the following is further given on the basis of the above embodiment: Figures 1-3

[0031] In order to make the glue solution in the high barrier film after gluing and leveling dry more fully, the following design is given in this embodiment:

[0032] The drying mechanism 4 includes drying covers 41, drying boxes 42, mounting plates 43, fans 44, and heating wires 45. The drying covers 41 are mirror images. Ventilation openings 46 are formed on the outer sides of the drying covers 41. The drying boxes 42 are arranged on the inner sides of the drying covers 41. Multiple ventilation grooves are formed in the middle of the drying boxes 42. The ventilation grooves are divided into air inlet grooves and air outlet grooves. The mounting plates 43 are arranged in the middle of the air inlet grooves and the air outlet grooves. The multiple fans 44 are arranged in the middle of the mounting plates 43. The fans 44 can provide power for the air in the air inlet grooves and the air outlet grooves. The heating wires 45 are arranged at the bottom of the air inlet grooves. The heating wires 45 can heat the air flowing in the ventilation grooves, so that the hot air can flow above the high barrier film after compounding. The air inlet grooves and the air outlet grooves are arranged in sequence. The air inlet grooves and the air outlet grooves arranged in sequence cooperate with each other, so that the hot air is quickly removed after drying the high barrier film, the hot air uniformly and fully dries the high barrier film, avoids the evaporation of the glue solution in the drying area due to poor ventilation, which affects the normal volatilization of the glue solution, and prevents the high barrier film from whitening due to insufficient drying, which affects the quality.

[0033] As an improvement of the above scheme, multiple drying boxes 42 are arranged at intervals on the inner side of the drying cover 41. Auxiliary drying assemblies are arranged between the drying boxes 42. The multiple drying boxes 42 can adjust the drying temperature and the air speed according to the volatilization stage of the glue solution. In the inlet area, the temperature can be relatively low, so that the glue solution is preliminarily volatilized, and air bubbles are avoided on the surface of the glue layer due to rapid boiling of the glue solution. The temperature is increased in the middle area to accelerate the volatilization of the solvent. The temperature is slightly reduced in the outlet area to make the glue layer stable and solidified, which is beneficial to improve the quality and stability of the high barrier film after compounding.

[0034] In this embodiment, the auxiliary drying assemblies are arranged in pairs. The auxiliary drying assemblies include adjustment boxes 47, electric push rods 48, and control frames 49. The electric push rods 48 are arranged in the adjustment boxes 47. The control frames 49 are arranged at the ends of the electric push rods 48. The leveling rods 491 are arranged on the inner sides of the control frames 49. The electric push rods 48 can control the pressure of the leveling rods 491 on the high barrier film body. When the high barrier film 6 is dried, the auxiliary rod assemblies can press and level the high barrier film body multiple times, so that the high barrier body always maintains good tension and close adhesion between multiple films during the drying process.

[0035] ​The implementation principle of the second embodiment is that after the high barrier film 6 is coated with glue, the high barrier film 6 will enter the drying mechanism 4, at this time, the electric fan 44 in the drying box 42 operates, the air heated by the heating wire 45 is blown on the surface of the barrier film body through the air inlet groove, at the same time, the air of the barrier film body is quickly sucked out by the air suction groove, so that the barrier film body is in a stable and uniform drying state, thereby preventing the evaporation of the glue liquid in the drying area due to poor ventilation, affecting the normal volatilization of the glue liquid, and preventing the high barrier film from being whitened due to insufficient drying, thereby preventing the quality of the high barrier film from being affected.
