This cohesive bandage production line / self adhesive bandage producing machine has the functions of high-precision spraying and dip coating. It has the advantages of two coating methods that can make the coating amount range very wide. It has the characteristics of high tension control accuracy, uniform coating, no scratch on the base material, and flat end face of winding and unwinding. The whole machine adopts the technologies of electric central control, frequency conversion speed regulation, hot air circulation spray drying, etc. to improve the quality of products with advanced technologies.
This equipment is mainly applicable to the production of bandage and cloth base coating. The width of the substrate can reach 1.1m, which is suitable for aqueous coating liquid. Fabric coating with glue uniformly, simple operation and convenient adjustment.
Main technic parameters: 1. Coating width: 450-1100mm adjustable 2. Roller width: 1200mm (diameter of guide roller in the oven 70~90mm) 3. Base material: bandage 4. Safety: protective cover shall be installed for each transmission section. 5. Coating liquid: solvent and water-based glue. 6. Coating technology: 1) adopt high-tech nozzle technology, and equip servo motor to precisely control the round-trip circulation direction of the nozzle. 2) When the maximum coating amount is 50g, the thickness deviation of dry glue per square meter is ±2G 7. Oven length: total length 20 (4m x 5 sections), flat bridge structure 8. Oven heating: electric heating (380V electric oven of heat exchanger is required) and hot air circulation. 9. Oven temperature control: the maximum temperature of hot air in the oven is 135°C, and the accuracy is ± 2°C. the temperature of 5 sections can be set and adjusted independently. 10. Unwinding and winding structure: unwinding and winding single station center type. 11. Unwinding diameter: unwinding Φ1000mm, roll core Φ76mm (1 inch) 12. Winding paper cylinder: 1-3 inches (Φ 76mm) paper cylinder. 13. Power configuration: the complete AC motor is equipped with a precision reducer, and the motor is made in China or imported 14. The winding edge is neat: ± 3mm 15. Transmission in the oven: stainless steel, mesh conveyor belt transmission, limited to prevent material stretching. 16. coating speed: 2-12m/min depend on oven
