In order to avoid deformation of the finished product produced by the bitumen carpet tile production line, on the one hand, the tension film of the traction substrate is reduced to be excessively stretched; at the same time, the flatness of the substrate is adjusted, and the position of the adjustment roller can be adjusted by adjusting the position of the adjustment roller. The flatness of the material. Of course, for personalized printing, we can also add some flattening rolls or bending rolls to the appropriate part before compounding to stretch the film.
On the other hand, in the process of adjusting the pressure of the composite roll of the bitumen carpet tile production line, special attention should be paid to adjusting the composite pressure between the two composite rolls. In addition, cleaning the composite roll and replacing the damaged rubber press roll can also prevent the composite product from wrinkling.
When designing the bitumen carpet tile production line, if a preheating roller is added before the composite to preheat the surface of the second unwinding substrate, the temperature of the second unwinding substrate and the coated substrate before the composite is substantially the same, It also prevents curling of the composite film after it has cooled.
