The transmission method of the second transmission gear 22 is the same as that of the first transmission gear, that is, the rotor of the second transmission motor 76 is fixedly connected to one of the second rotating shafts 21, and the second transmission motor 76 can drive the second rotating shaft 21 to rotate, thereby driving the second transmission gear 22 corresponding to the second rotating shaft 21 to rotate. Since the second transmission gears 22 are meshed with each other, the rotation of one of the second transmission gears 22 can be driven to drive the other transmission gears to rotate.

[0072] Please refer to Figure 3 A fifth door-type support frame 77 is fixed on the right side of the glue-applying support 1, and an exhaust funnel 78 is horizontally fixed on the fifth door-type support frame 77. The exhaust funnel 78 is connected to the external air cooling dryer through an air pipe. In this embodiment, the external air cooling dryer blows the cooled and dry air to the surface of the paper after glue coating through the exhaust funnel 78, so as to achieve the effect of quickly cooling the glue on the surface of the paper, so that the glue is quickly and evenly attached to the surface of the paper, reducing the influence of factors such as the external environment.

[0073] Working principle: adjust the distance between the first adjustment limit plate 53 and the second adjustment limit plate 54, and the distance between the third adjustment limit plate 57 and the fourth adjustment limit plate 58 respectively, so that the above distances are adapted to the width of the paper 81, and the paper 82 to be glued is conveyed above the first glue guide roller 2 and the third glue guide roller 4, and after passing through the fourth glue guide roller 5, it is guided to the bottom of the second glue guide roller 3. During the guiding process, the paper will be limited between the first adjustment limit plate 53 and the second adjustment limit plate 54, and between the third adjustment limit plate 57 and the fourth adjustment limit plate 58.

[0074] When the paper 81 is guided to the bottom of the first glue application box 10, the first glue application liner is attached to the surface of the paper through the first telescopic cylinder 32 and the second telescopic cylinder 35, and the glue discharge cylinder 68 is started to move downward. With the cooperation of the booster pump 70, the glue in the glue discharge box is discharged into the interior of the first glue application box 10 through the first glue delivery pipe 8 at a constant pressure, and is discharged into the interior of the first glue application disk 16 through the first glue inlet hole 15, and then discharged through the first glue application hole 18. The first transmission motor 74 is started to drive the first glue application disk 16 to rotate. At the same time, the first regulating cylinder 37 drives the first glue application box 10 to move back and forth on the surface of the paper, so that the glue is evenly applied to the surface of the paper 81.

[0075] When the paper 81 is guided to the bottom of the second glue application box 19, the second glue application liner is attached to the surface of the paper through the third telescopic cylinder 43 and the fourth telescopic cylinder 47, and the glue discharge cylinder 68 is started to move downward. With the cooperation of the booster pump 70, the glue in the glue discharge box is discharged into the interior of the second glue application box 19 through the second glue delivery pipe 9 at a constant pressure, and is discharged into the interior of the second glue application disk 25 through the second glue inlet hole 24, and then discharged through the second glue application hole 80. The second transmission motor 76 is started to drive the second glue application disk 25 to rotate. At the same time, the second regulating cylinder 45 drives the second glue application box 19 to move back and forth on the surface of the paper, so that the glue is evenly applied to the surface of the paper 81.

[0076] When the glued paper 81 is guided to the exhaust funnel 78, the dry cold air blown out by the exhaust funnel 78 will quickly cool and dry the glue on the surface of the paper 81, so that the glue is quickly and firmly attached to the surface of the paper.

[0077] During the gluing process, the height of the fourth gluing guide roller 5 is adjusted by the fifth telescopic cylinder 63 and the sixth telescopic cylinder 65 so that the paper 81 maintains a certain tension.
