The bottom support 162 is connected to a hot sealing glue return plate 164, and the outlet of the hot sealing glue return plate 164 is connected to one side of the hot sealing glue pool 1.

[0025] It should be noted that, in this embodiment, the height of the first guide roller 12 is lower than the height of the coating and feeding roller 14 to ensure that the bottom of the aluminum foil at the bottom of the first guide roller 12 is closely fitted with the top of the coating and feeding roller 14, thereby ensuring the subsequent application of the heat-sealing adhesive. The height of the scraper roller 163 is slightly higher than the coating and feeding roller 14, thereby ensuring that the excess heat-sealing adhesive material adhering to the aluminum foil is collected without damaging the thickness of the heat-sealing adhesive applied on the aluminum foil, thereby ensuring the quality.

[0026] Furthermore, by arranging an excess heat-sealing adhesive collecting assembly 16 on one side of the coating feeding roller 14, on the one hand, the uniformity of the coating thickness of the aluminum foil is ensured, and on the other hand, the aluminum foil is prevented from adhering to the excess heat-sealing adhesive due to other reasons, and the excess material is collected, so as to ensure the yield rate, improve the production efficiency, reduce the cost, and ensure the consistency and quality of the product;

[0029] It should be noted that, in this embodiment, a heat-sealing glue sedimentation stirring component 2 is provided inside the heat-sealing glue pool 1 at the bottom of the coating and feeding roller 14, and the glue inside the heat-sealing glue pool 1 is stirred by the heat-sealing glue sedimentation stirring component 2 to prevent the glue from sedimentation, and the heat-sealing glue sedimentation stirring component 2 is fixed on the outer end of the coating and feeding roller 14;

[0032] When in use, an external driving device drives the smearing feeding roller 14 to rotate, and the bottom of the smearing feeding roller 14 dips the glue inside the heat-sealing glue pool 1. When the heat-sealing glue dipped on the outer wall of the smearing feeding roller 14 reaches the glue thickness limiting roller 15, the thickness between the glue thickness limiting roller 15 and the smearing feeding roller 14 is the thickness of the smearing heat-sealing glue, and the excess smearing heat-sealing glue is limited and removed by the glue thickness limiting roller 15. The smearing feeding roller 14 rotates to evenly smear the medicinal aluminum foil. The moving rod 24 is connected to the fixed flange 21, and the fixed flange 21 is connected to the end of the coating and feeding roller 14. The stirring rod 24 follows the movement of the coating and feeding roller 14 to stir. The stirring rod 24 makes a circular motion to stir the glue inside the heat-sealing glue pool 1.

The collected heat-sealing glue enters the heat-sealing glue pool 1 through the heat-sealing glue reflux plate 164.
