Equipment Introduction
The single-sided water-based membrane coating machine is composed of a unwinding unit, a preheating unit, a traction coating unit, an electric heating hot air oven drying unit, a shaping cooling unit, a winding unit, and an electronic control system; Apply the stirred slurry evenly on the substrate, ensuring that the size, weight, etc. are within the design specifications. After drying and shaping treatment, roll it up to prepare for the subsequent process. This machine is suitable for evenly coating water-based coatings on electronic diaphragm layers. This machine integrates light, machinery, and electricity, and is carefully designed, manufactured, and assembled. It has uniform coating, neat winding surface, stable running tension, and convenient operation, making it an ideal water-based coating equipment for diaphragms.
Characteristic DescriptionThe control adopts COTRUST PLC, with stable operation and user-friendly operation;
The unwinding and rewinding are automatically changed at two workstations, saving time and improving efficiency
The unwinding and correction system adopts a universal source ultrasonic correction system, which is sensitive in action and has high accuracy;
The winding correction adopts a universal source ultrasonic belt misalignment function correction system, which is sensitive in action and has high accuracy;
The winding meter can be stored multiple times and historical records can be displayed;
The coating is sealed scraper kiss coating, with controllable accuracy and uniform adhesive application
Traction vacuum roller traction reduces film scratches and improves product quality
The guide roller of the oven adopts a fully active transmission to overcome tension fluctuations caused by membrane thermal deformation
Winding gap type follow-up pressure roller ensures stable winding tension
The mechanical design, processing, and assembly standards of the entire machine are unified, and the wall panels are processed in pairs. After annealing treatment, they are bored and milled multiple times in the machining center, ensuring the precision of the entire machine
