Description
Technical field
The utility model relates to a kind of paper making equipment, especially a kind of positive and negative coating sizing applicator.
Background technology
The production of general printing paper is divided into paper pulp and two basic processes of papermaking, and slurrying is exactly with the method for machinery, the method for chemistry or the method that both combine, plant fiber material to be become true qualities paper pulp or bleached pulp from solution.Papermaking is the paper pulp fiber that is suspended in water, is combined into through various processing the page that conforms with various requirement.The enough use raw material of 4～6 months generally need be stored in the paper mill, makes raw material process spontaneous fermentation in storage, is beneficial to slurrying, guarantees simultaneously the continuous production of paper plant.Through material papering section, the raw materials such as reed, wheat straw and timber are cut into tablet (for producing chemical pulp) or wood disconnected (for producing ground wood pulp), again little tablet raw material is put into and adds chemical liquid in boiling vessel, carry out boiling with steam, raw material is cooked into paper pulp, or wood is forfeited worn into paper pulp on wood grinder, also can regrind into paper pulp through boiling to a certain degree.Then with a large amount of clear water, paper pulp is washed, and by screening and purification, thick sheet, knot, stone and sand etc. in slurry are removed.According to the requirement of paper kind, with bleaching agent, paper pulp is floated to desired whiteness again, then utilizes beating equipment to pull an oar.Then add the various auxiliary materials such as the filler that improves paper performance, sizing material, sizing agent in paper pulp, and again purify and screen, serving at last paper machine batches, and carries out cutting and rewinding or cut producing roll web and sheet paper through wet end drainage, press dewatering, cylinder dried, press polish.If produce and to produce coated printing paper, need dry middle part or produce roll web to realize by coating processing.
Existing coating applying glue equipment is of all kinds, but otherwise be exactly to involve great expense, if it were not for being exactly complicated operation, waste time and energy, cause the papermaking cost to increase.
The utility model content
Problem to be solved in the utility model is to improve the problem of positive and negative coating sizing applicator in background technology.
in order to overcome the above problems, the utility model provides a kind of positive and negative coating sizing applicator, comprise the material loading back flow roll, the first dip coated roller, the second dip coated roller, the 3rd dip coated roller, the coating metering roll, the first elevating hopper, the second elevating hopper and a plurality of live-roller, described the first elevating hopper, in the second elevating hopper, coating liquid is housed, described the first dip coated roller and material loading back flow roll side by side corresponding and they between leave a gap, described coating metering roll and live-roller side by side corresponding and they between leave a gap, the latter half of described the first dip coated roller is soaked in the coating liquid in the first elevating hopper, described the second dip coated roller, the latter half of the 3rd dip coated roller is soaked in the coating liquid in the second elevating hopper, described the second elevating hopper is higher than the first elevating hopper.
Described paper is provided with drying plant from the outlet correspondence that the gap between coating metering roll and live-roller passes.
