2. Basic process flow
The main equipment is composed of manual feeding→ uncoiling unit I, II→ two-roller clamping machine I→ two-roller clamping machine II→ head shearing machine (two groups), → welding machine→ riveting machine→ flattening roller→ tensioning machine I (four rolls), → inlet loop→ double roller centering mechanism I→ tensioning machine II (S roller) → pre-degreasing → roller brushing machine I→ degreasing → roller brushing machine II→ washing I→ washing II→ pure water washing→ hot air blowing device l→ chemical roller coating machine→ passivation drying oven→ forced air cooling device → tensioner III. (S roll) → S roll centering mechanism→ primer roller coating machine→ primer leveling→ primer curing furnace→ forced air cooling device 2→ primer strong cooling chamber (water cooling) S roller → S roller centering mechanism III.→ hot air blowing device 2→S roller tensioner IV.(S roller) → turn to centering mechanism IV. (S roller) → topcoat roller coating machine 1.2→ topcoat leveling→ topcoat curing furnace→ forced air cooling device 3→ topcoat strong cooling chamber (water cooling) → S roller centering mechanism V.→ hot air blowing device 3→ tensioning machine V. (double S roller) → outlet loop → centering mechanism VI. (double roller) → cold laminating unit→ S roller tensioning machine VI. (S roller) → belt clipping shearing machine III.→ two-roller clamping machine IV.→ servo retractionThe winding unit → manual discharge (with belt rewinder). The main equipment also includes electronic control system, hydraulic system, and pneumatic system. Auxiliary equipment also has a steel coil mobile trolley.
