JLH-TB1100 Self-adhesive bandage coating machine 1. Equipment overview This equipment has the functions of high-precision spraying and dipping. It has two coating methods, which can make the coating amount range widely, with high tension control precision, uniform coating, no scratches on the substrate, and smooth winding and unwinding end faces. The whole machine adopts electric central control, frequency conversion speed regulation, hot air circulation jet drying and other technologies to improve the quality of products with advanced technology. 2. Scope of application: This equipment is mainly suitable for the production of bandage and cloth-based coating. The width of the substrate can reach 1.1M, which is suitable for water-based coating liquid.
Main technical parameters: Coating width: 450-1100mm( adjustable) Roller width: 1200mm (diameter of guide roller in the oven is Φ70~90mm) Substrate material : Bandage Safety: Protective cover is installed for each transmission part. Coating liquid: Solvent-based and water-based glue.
Coating technology:
A : Adopt high-tech nozzle technology, and then equipped with servo motor to precisely control the reciprocating circulation direction of the nozzle.
B: when the maximum coating amount is 50 grams, the deviation of dry glue thickness per square meter is ±2 grams. Oven length: total length 20 (4M × 5 sections), flat bridge structure. Oven heating: Electric heating (380V electric heating box required to enter the heat exchanger), hot air circulation. Oven temperature control: The hot air temperature in the oven is up to 135°C, the accuracy is ±2°C, and the 5-stage temperature independent control can be set and adjusted. Unwinding and rewinding structure: Unwinding and rewinding single-station center type. Unwinding and rewinding diameter: Unwinding Φ1000mm, core Φ76mm (1 inch). Rewinding paper tube: 1-3 inch (Φ76mm) paper tube can be used. Power configuration: ac motor with precision reducer, motor made in China or imported rolling edges neaty : ±3mm Transmission in oven: stainless steel, mesh conveyor belt, limited to prevent material stretching.
