A permanent magnet brake is provided on one side of the loading roller 3231, and the permanent magnet brake is used to drive the loading roller 3231 to rotate. The recovery roller 3232 is connected to the fixed plate 321 and is located below the loading roller 3231 for recovering the back adhesive tape roll. The guide roller group 3233 is connected to the fixed plate 321. The guide roller group 3233 is located between the loading roller 3231 and the recovery roller 3232 and is used to guide the back adhesive tape to wind around the tape tearing platform 3222. If the manipulator directly tears off the back adhesive, it will cause the back adhesive to wrinkle or even be damaged. Therefore, using the tape tearing platform 3222 assembly to replace the manipulator to tear off the back adhesive can avoid the back adhesive from wrinkling or being damaged and obtain a complete back adhesive. The utilization rate of the back adhesive is improved. The tape tearing platform 3222 moves back and forth under the drive of the connecting plate 3221 to tear off the back adhesive.

[0096] In this embodiment, the film tearing device 4 has the same structure as the tape tearing platform 3222 assembly.
