-
Product description
Automatic production line: discharging, primer, primer drying, surface coating, surface coating drying, cooling, material storage, automatic winding.
1. The unwinding unit can realize non-stop coil change, continuous production, improve production efficiency and reduce waste.
2. Precision roll coating, imported precision screw adjustment to control the coating amount, accurate measurement.
3. Drying oven, traditional side door opening or cylinder opening and closing type, filled with rock wool for insulation, each group of drying oven is equipped with proportional valve for independent temperature control, and high temperature resistant and antistatic canvas conveyor belt is used to transport the film to prevent stretching
4. Tension control system, the whole machine adopts floating roller and tension detector for segmented tension control, so as to keep the material running smoothly, without wrinkle and small shrinkage
5. The material storage mechanism adopts linear guide rail and precision guide wheel to store materials up and down, makes rational use of space, and the storage length can reach 12m
6. Automatic surface coiling, automatic tube taking, automatic coiling, automatic cutting, automatic coiling without shutdown, reducing manual operation and accurate meter counting.
