• Adopting the negative pressure structure of cover suction type, high pressure fan makes the corrugated paper stick on the corrugated roller. It is convenient for gluing and bonding, simple structure and convenient maintenance.
• The frame is made of high-grade cast iron with high strength, good shock absorption and no deformation after tempering.
• The corrugating roller is made of 50crmoa alloy steel, Quenched and tempered, medium frequency quenched and polished. The diameter of the main corrugating roller is 292mm, and the surface of the corrugated roller is tungsten carbide tile roller or chrome plated. High temperature resistant double row roller bearings are used for pad roller and pressure roll bearing. High temperature grease lubrication. Pressure roller. The corrugated roller is pressurized by air bag, which has good buffering effect, long service life and maintenance free.
• The gluing unit can be moved out horizontally as a whole, and it is easy to disassemble and maintain. The cylinder controls the gluing and de gluing action sensitively. The copper plate scrapes and scrapes the glue cleanly. The electric rubber baffle controls the gluing width. The angle sensor, PLC and touch screen are adopted. According to different paper, different speed automatic control glue quantity, no accumulated error.
• The main engine is equipped with large diameter preheater, with concentrated heat and large preheating area, without additional preheating device, and the lower preheating roller is ￠ 600mm. Upper preheating roller ￠ 400mm. Reasonable matching, electric adjustment of preheating angle area. The core paper is equipped with humidifier.
• The gear box universal shaft transmission is adopted, and the gear is hardened by high frequency quenching. Oil bed lubrication, lifetime. Variable frequency motor speed control, energy saving and high efficiency.
