Paper folding rate is greatly reduced, and reduces the use rate of paper to greatest extent.
Working principle of the invention is as follows: by taking 5 layers of corrugated board as an example, when work, steam-admission main pipeline 1 is concentrated by cogeneration of heat and power
Heat supply, therefore, a saturated vapor in steam-admission main pipeline 1 can only achieve 140-160 DEG C of temperature, pressure 5-6kgf/cm2, two
Preheater 5, preregulator 2, pressure roll 7 and Corrugator roller 6 on group single side unit pass through a saturated vapor of above-mentioned low-temp low-pressure
Heating, low-temperature heat reduce the destruction to original paper fiber, ensure that the stabilization of physical index；Preheated, pressure roll 7
With the extruding of Corrugator roller 6,4 gluing of single-side machine, molding, produce two layers of one-sided corrugated board, then multiple preheater 8 to facial tissue into
Row preheating, through 9 gluing of Double-plate machine, molding, two layers of one-sided corrugated board is molded as one with facial tissue, completes 5 layers of corrugated board
Production；In the process, the hot plate 1 of Double-plate machine, hot plate 2 11, hot plate 3 12 are heated using a saturated vapor, out
After the separation of steam-water separator 17, steam is heated to hot plate 4 13 and is used the back-steam come, and water is discharged to through energy-saving type drain valve 15
Backwater main pipeline 14, the return water after 4 13 use of hot plate are discharged to backwater main pipeline 14 through energy-saving type drain valve 15 again.At this point, raw
The temperature and the environment temperature temperature difference of 5 layers of corrugated board of output are smaller, therefore, will not distribute because of heat, moisture during storage
Cause cardboard prying modification.
