Product Description 1. The main technical parameterPaper typesthermal paperBase weight 40-100 g/m2Operating Speed80-110 m / min Designed speed 120 m / min (50Hz)Coating typedouble blade knife coaters, three-roller type back coaterCompressed air pressure0.6-0.7 Mpa Saturated steam pressure0.6-0.8 Mpa Coating weight2-20 g/m2 for per coaterDrying typehot air blowing, one sideFinishing typehot cylinders and calenderingMaximum dimensionslength 27500mm, width 5300mm, height 4140mm2. Main structure2.1 The unwinding deviceUnwinding stand is of uniaxial type, with tension control device and magnetic brakes(or motor brake).Pneumatic core shaft: Φ74x1400mm, 2 setsRack is equipped with adjustable frame, the position of the base paper can be adjusted in coating machine. The new paper reel can be prepared on the rack when machine running.2.2 Blade knife coater, 2sets1. Color feeding rollerDiameter / roller width: Φ270x1400 seamless steel pipe, chrome-plated, roller bearings SN208Chrome thickness: 0.1mmQuality assurance: the roller surface roughness: Ra0.05 Roller surface runout: ≤0.01mm Roller surface without wear marks, punch point, thread marks Feeding roll with separate AC variable frequency drive motor, according to process requirement, the feeding roll speed can be adjusted. 2. Backing rollerDiameter / roll width: Ф450x1400, steel rolling, roller bearing SN515Covering Material:High-quality neoprene synthetic rubber Rubber Hardness :Shore 78 o ± 2Cladding thickness: 18mmRoller surface runout: ≤0.02mm3. Paint trayPaint tray made of 1.5mm thick stainless steel SS304, divided into the feed chamber, overflow chamber and backflow chamber, inlet port at the bottom of the trough, in order to promote the liquidity of paint. In the trough it should avoid stagnant dead zones to prevent coating caking; back flow is about 80% of total flow, feed roll manually lifted, with flexible lifting and falling. 4. Coating metering unit The range of Blade angle adjustment:0 ° -30 ° Arm moving:pneumatic cylindersScraper beam is steel plate welded structure. Rotating bearing is plain bearings.Banner coating weight single-point adjustment device is accurate screw thread device. The adjustment spacing of banner coating weight is 50mm.5. Compressed air control systems, 2 sets Equipped with air source treatment components and control components for coater to act: Feeding roller moving Coating tray moving Scraper blade clampingFine tune is between feeding roller and backing roller, to control the clearance between the two rollers. 6. Machine frame: welded by steel plate and profile steel,thought aging treatment.2.3 Hot air drying systemThe system consists of single-sided hot air oven, draught fan, heat exchanger or the gas burner, ventilation door, and air duct.1. Hot air oven, 3 sets Single-sided hot air dryer, of unit form, made of welded profile steel, inner and out surface coated by 1mm steel plate, in the middle it is 50mm thick insulation materials to ensure the inner temperature and ambient air temperature does not exceed 20oC. Air duct made of 1mm galvanized steel plate. Spray nozzle is made of 1.2mm thick profile aluminum alloy with uniform gap. Spray slit width 2.5-3mm.Guide rollers in ovens: Φ100×1400,12 sets in total, roller body of aluminium, roller bearings P205.2. Hot air system, 3 sets Consists of heating fan, heat exchangers or gas burner, filters, ventilation door, air duct.Air ducts of 1mm galvanized steel sheet.Aluminum fin heat exchanger, model LZ1000*1000, each group of 3 pieces, 3 groups in total. If choose the burners, the air stove is direct-fired type, no heat exchange equipment, the system automatically controls the switch, gas and energy efficiency is high.Draft fans: model, 4-72-6C; motor power,7.5kWHeat source: option A: boiler capacity:at least 0.5T/houroption B: gas burner, JG10D(max gas consumption 10 cubic/hour), 3 pieces in all, plus a boiler of 200kg/hour for hot cylinder.2.4 Back coating system, 1 set1.
