From the earliest PP material to the popular AR material today, it has gone through more than 5 years of development and has been slowly accepted by the majority of people. In the production process of the existing protective film, in order to ensure that the cut protective film moves along the specified direction on the conveyor belt, two limit plates are usually added above the conveyor belt to make the protective film move along the two limit plates. However, when the protective film is on the conveyor belt, it will be squeezed with the limit plate, causing the protective film to bend and fold, which will affect the subsequent process; therefore, a protective film guide device is proposed to address the above problems.
