Description

Technical Field

[0001] The utility model belongs to the technical field of paper protective film production, in particular to a calendering device for producing paper protective film. Background Art

[0002] Paper protective film is a covering layer applied to the surface of paper, which is mainly composed of two main components: substrate and coating. Its main function is to provide paper with additional waterproof, oil-proof, anti-fouling, anti-wear and other properties to extend the life of paper and improve its performance.

[0003] There are some disadvantages in the use of calendering equipment, such as: the calendering equipment cannot compact paper protective films of different thicknesses, resulting in a reduced range of use of the device. At the same time, the calendering equipment cannot adjust the size and angle of the air blowing when dissipating the paper protective film. A large air blowing volume may cause the thinner paper protective film to be directly impacted and damaged. The concentrated wind force can only quickly dissipate the heat of the thicker paper protective film. The air outlet angle cannot be dispersed, which may cause the thinner paper protective film to be blown crooked. In view of this, we propose a calendering equipment for the production of paper protective film. Utility Model Content
