Not only is the rolling efficiency low, but the width of the rolled protective film is fixed and the adaptability is low. Therefore, a separation rolling device for protective film processing is needed to solve the above problems. Utility Model Content

When the two movable plates that are close to each other move to a suitable position, the winding roller can be divided into three winding structures outside, and the motor is controlled to work. The rotating winding roller can roll up three groups of protective films of different sizes according to actual conditions, and the rolling efficiency is high. In the rolling process, the three groups of protective films are separated by two groups of several piston rods;
