SF-360-2500 Model Quick Change Roll Type Single Facer Hood Suction Structure

SF-360-2500 Model Quick-Change Roll Type Single Facer

Structural features:

• Main corrugated roller: ￠360mm (depending on the type of corrugated), pressure roller ￠415mm, preheating roller ￠400mm.
• The negative pressure design is adopted, and the heat loss is low, so that the core paper can be evenly pressed and attached to the surface of the corrugated roller, so that the corrugated paper can be better formed. Because the pressure is even, the top of the corrugated paper can be better and evenly coated with glue, so that the single-sided corrugated paper can be better fitted.
• Quickly change the roller, about 15 minutes, when changing the corrugated roller, use a trolley to drag the whole set of corrugated rollers into the machine, fix it on the machine base, and lock it with just one button switch to quickly and easily complete the fixing of the corrugated roller.
• The corrugated roller is made of 48Crmo high-quality alloy steel, and is heat-treated: quenching and tempering-rough turning-inner hole fine boring-shaft head baking-welding-tempering stress relief-fine turning-rough grinding-intermediate frequency quenching-CNC grinder fine grinding-tungsten carbide treatment. Surface hardness is above HRC60. The diameter of the corrugated roller is ¢360mm, and the surface hardness is above HRC60. The bearings of the key parts of the roller and the pressure roller are Havalo bearings.
• The pressure roller is ¢415mm, the surface is ground and chrome-plated; the air pressure controls the up and down movement, and the material is medium carbon steel No. 45, quenched and tempered.
• The glue roller unit adopts an overall external moving structure, which can be moved out of the machine for maintenance during maintenance, which improves work efficiency; the diameter of the glue roller is ￠270mm, and the surface is polished and engraved with 30 lines of pit-type mesh processing and hard chrome-plated. The surface of the scraper roller is polished and hard chrome-plated.
• The glue coating part can be moved as a whole, and the replacement of the glue coating roller is quick and convenient.
• The preheating roller adopts a seamless steel pipe produced by Tiangang ¢400mm, all connected with metal hoses
• The corrugated roller, pressure roller, etc. adopt a highly stable airbag control system, and also have a pressure control buffer effect.
• The glue quantity control is electrically adjusted, the glue isolation device is electrically operated, and the glue coating system can operate independently when the main machine stops to prevent the glue from drying up.
• The mobile glue coating system is not only easy to clean, but also more conducive to maintenance and repair work.
• The simple operation control system, touch screen operation interface, and color graphics display the operation status, function selection, fault indication, troubleshooting and parameter setting, which can show that this machine is fully functional, easy to operate and user-friendly.
• The built-in pre-adjuster with spray system adjusts the temperature and moisture of the core paper.
• The main and auxiliary corrugated rollers and pressure roller bearings are all made of high-temperature grease to ensure the bearing life and smooth operation.
