The invention discloses a paper sheet pressing machine with graphite press plates. The paper sheet pressing machine comprises a bracket, a stainless steel nut, a screw rod, an upper press plate and a lower press plate; and both the upper press plate and the lower press plate are respectively of a steel steel-lining graphite structure, in each steel lining graphite structure, the inner part is full of graphite, and the outer side is coated by steel. The paper sheet pressing machine with the graphite press plates, disclosed by the invention, has corrosion resistance, ensures that the upper and lower press plates are smooth, is long in service life, and ensures that after being pressed, a wet paper sheet manufactured and sheeted in a lab is characterized by uniformly-reduced moisture, evenly-distributed fibers, and flat surface.
Description
technical field [0001] The invention belongs to the field of papermaking equipment, and in particular relates to a paper press machine with a graphite pressing plate. Background technique [0002] The working principle of the paper sheet press machine used in the laboratory sheet copying: use the stainless steel screw connected to the upper pressing plate to adjust the position of the upper pressing plate to fix it, put the formed wet paper between the upper and lower pressing plates, and use an absorbent cloth between the pressing plate and the wet paper separated. Start the hydraulic pump to make the lower platen rise and press the wet paper sheet with the upper platen, thereby increasing the density and smoothness of the hand-sheet, reducing the moisture content of the paper sheet, and increasing the strength of the hand-sheet. The material for making the upper and lower pressure plates is usually stainless steel, which can prevent rust. However, various chemicals are u...
