Once a paper machine enters the maintenance period, the doctor blade is often easily overlooked. But some simple routine maintenance can keep this device running efficiently and continuously.1. The first very effective routine is to replace the doctor blade as often as needed.
(1) Key points of starting and stopping operation of the wire part of the paper machine:1. Check whether all parts are in good condition, and remove the sundries on the equipment, especially the inside and outside of the net.2. Drop the scrapers of each guide roller and breast roller
When the soft calender and hard calender leads the paper, the paper threading device must be used to lead the paper. Lead paper During the process, when the paper threading device fails, it must be overhauled before the threading device can continue to be put in.
It is widely used in coated white paper and other paper types. Features: The surface hardness of the hard roller is large, and the thickness of the paper is balanced by the action of high temperature and high pressure on each area.
Due to the knowledge of the calender, the soft roll surface material rebounds, so that the roll surface can adapt to any poor uniformity and quantitative changes of the paper. The thinner area of the paper is in contact with the heat roller, and for the thicker area, the thickness will not be greatly reduced. Such thick and thin areas can increase its fine smoothness and eliminate stains.
