[0036] Working principle: first, start the motor 3, the output shaft of the motor 3 through the output shaft 1 4 drive two gear 5 synchronous rotation. Gear 5 through the meshing connection with rack plate 8, drive rack plate 8 in the sliding hole 1 6 and sliding hole 3 32 inside up and down sliding. The sliding of the rack plate 8 drives the rotating shaft 9 to move up and down accordingly, and the rotating shaft 9 drives the tensioning roller 10 to move synchronously. In the process of the tensioning roller 10 rising or falling, the tensioning degree of the adhesive tape can be effectively adjusted. In this way, the uneven gluing caused by insufficient tension of the adhesive tape is avoided, and the tension stability of the adhesive tape during gluing is ensured.

[0037] Next, start the heating rod 20 located in the containing box 19, heat the glue in the containing box 19, prevent the glue from solidifying due to cooling in low temperature environment.

The function of the scraper 31 is to scrape the glue dropped on the outer surface of the adhesive tape after the glue dropping of the glue outlet head 25 is completed, so that the glue is uniformly distributed on the surface of the adhesive tape. In this way, not only the uniform gluing can be ensured, but also the accumulation or uneven thickness of the glue can be avoided, thereby improving the product quality of the adhesive tape.
