[0015] Beneficial Effects

[0016] The utility model provides a bubble-free winding device for protective film processing. Compared with the prior art, it has the following beneficial effects:

[0017] (1) The bubble-free winding device for processing the protective film is provided with a fixed seat, a first motor, a rotating shaft and a first connecting plate. After the protective film is wound up, the first motor is started, and the first motor drives the first connecting plate to rotate through the rotating shaft. The first connecting plate drives the second motor and the winding roller to rotate, so that the winding rollers on both sides are replaced. When the staff removes the wound protective film, the second motor drives another winding roller to rotate to wind up the protective film. A new protective film can be wound up while the protective film is disassembled, thereby increasing the winding speed and improving the work efficiency.

[0018] (2) The bubble-free winding device for processing the protective film has a tensioning mechanism. The pressure roller squeezes the protective film on the supporting roller under the action of the spring. The pressure roller increases the resistance of the protective film when it moves, thereby ensuring that the protective film between the pressure roller and the winding roller is always in a tensioned state, ensuring that wrinkles and bubbles are not generated during the winding process of the protective film, and ensuring the winding quality of the protective film; starting the first cylinder, the first cylinder drives the second connecting plate to move downward, and the second connecting plate squeezes the spring. The pressure of the spring on the moving frame increases, thereby increasing the squeezing force of the pressure roller on the protective film, thereby adjusting the resistance of the protective film during the winding process.
