Structure description
1. Color feeding roller
Diameter / roller width: Φ270x2100, 20# carbon steel seamless
steel pipe, chrome-plated, roller bearings SN510
Chrome thickness: 0.06mm
Quality assurance: the roller surface roughness: Ra0.5
Roller surface runout: ≤0.01mm
2. Backing roller
Diameter / roll width: Ф490x2100, 20# carbon steel rolling, roller bearing SN516
Covering Material:High-quality neoprene synthetic rubber
Rubber Hardness :Shore 78 º ± 2
Cladding thickness: 20mm
Roller surface runout: ≤0.02mm
3. Paint tray
Paint 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 cylinders
Scraper beam is steel plate welded structure. Rotating bearing is plain bearings, model GE80ES. 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 clamping Fine 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.
7.drive type:
Roller is drove by the hardened tooth surface reducer, inverter motor, coupling, and other components. Backing roller, 5.5kw, feed roller, 1.5kw.
