Product Description
Corrugated cardboard production line
Pit machine fully closed wallboard, high thickness casting base, large area positioning surface structure, large and small roll structure, oblique low center of gravity design, flip paste seat structure.
The soft contact structure of pressure roll and paste roll of pit machine is easy to adjust.
Double-sided stacked structure, three-point support structure, split drive main drive.
Pit machine cavity tube core paper, pit arc plate, peripheral heating Corrugated Roller, cavity tube hot cylinder, double-sided cavity tube inlet arc plate, cavity tube hot plate, steam spray hot plate.
Pit machine 4 groups of proportional valve control, double-sided machine four groups of proportional valve control, steam pressure fine regulation, production line steam secondary utilization, return water pressure back to the boiler to achieve the third utilization of steam. Realize the efficient utilization of steam system.
The high efficiency transmission chain design, such as direct connection, synchronous belt, precision gear and bevel gear, is adopted to realize the high efficiency and energy saving of the transmission system, such as energy saving and high efficiency motor, closed loop vector frequency conversion drive and so on.
The high precision structure of glue gap, the precision adjustment of gap in electric cylinder transmission, the slurry supply system of diaphragm pump and the automatic feeding system can realize the efficient and non-destructive transportation of glue. The pit machine is standardized with a water cooler to cool the hydraulic system and reduce the temperature of the pulp basin at the same time, so as to prevent a large amount of condensation of glue at low gelatinization temperature.
