Abstract

The utility model relates to a kind of paper forming devices, belong to pulp technology for making paper.Including drive roll, forming net, overflow launder, table roll, suction box, deflector roll, into stock tank and net slot;Overflow launder and the two sides that net slot is respectively arranged on into stock tank, drive roll are fixed in rack with deflector roll and are connected by forming net, and table roll and suction box form arc-shaped structure and surround outside by forming net;The upper surface of suction box is covered with aperture, two sides are equipped with table roll, top is equipped with exhaust tube.The utility model structure is simple, easy to use, solves the problems, such as the quantitative unevenness of paper or so, while independent suction box solves the problems, such as that negative pressure is consistent in cylinder mould machine cylinder mould machine cylinder mould, keeps paper even closer, improves the quality of paper.

Description

A kind of paper forming device
Technical field
The utility model relates to a kind of paper forming devices, belong to pulp technology for making paper.
Background technique
Paper machine forming part structure and performance have decisive role to the formation of page and the quality of paper.Forming part is main Effect is to be dehydrated finely dispersed fiber, forms uniform l Water Paper, obtains highly organized wet web.Established paper web It is dewatered to certain mass dryness fraction (moisture of 95% or more removing), is the most important part of paper machine, affects yield and quality.
Currently, conventional papermaking constant part has long mesh paper making machine, cylinder mould machine, paper machine of the laminated network and open type oblique net paper machine. Long mesh paper making machine, cylinder mould machine, the online concentration of open type oblique net paper machine are high, and fiber is easy wadding and gathers, and the paper evenness of formation is poor, breathe freely Property is poor, and pulling force ratio can not be adjusted page in length and breadth, not be able to satisfy the needs of speciality paper.Oblique net paper machine produces sheet uniformity very great Cheng Degree depends on pulp distributor, and left and right is quantitatively poor to be difficult to control;Cylinder mould machine can generate lumps in forming process, and fiber is easy wadding It is poly-, cause the phenomenon that paper is irregular.
Utility model content
The technical problems to be solved in the utility model is in view of the deficiencies of the prior art, to propose a kind of paper forming device, Arc-shaped structure is formed by suction box and table roll, the quantitative unevenness of paper or so is solved the problems, such as, keeps paper even closer, mention The high quality of paper.
In order to solve the above technical problems, the utility model provides a kind of paper forming device, including drive roll 1, forming net 2, overflow launder 3, table roll 4, suction box 5, deflector roll 6, into stock tank 7 and net slot 8;Overflow launder 3 and net slot 8 is respectively arranged on into stock tank 7 Two sides, drive roll 1 and deflector roll 6 are fixed in rack and are connected by forming net 2, and table roll 4 and suction box 5 form arc-shaped structure And outside is surrounded by forming net 2;The upper surface of the suction box 5 is covered with aperture, two sides are equipped with table roll 4, top is equipped with exhaust tube 9, suction box 5 is each independent from each other, and can individually be controlled the negative pressure value of each suction box, be opened on each 5 panel of suction box There are numerous small holes, under the pumping of exhaust tube 9, liquid can be flowed away by aperture by exhaust tube, and fiber is retained in wire side, be formed Paper.
In the utility model, forming net can be the metal meshes such as stainless (steel) wire, copper mesh, nylon wire, polyester webs or organic material Expect net;Table roll is the cylinder deflector roll that can be freely rotated, and reduces the friction of forming net and suction box.
When the utility model is used, slurry flows into net slot into stock tank, then flows into net slot, to slurry overflow to overflow When slot, the negative pressure value 0.001MPa-0.02MPa of each suction box is adjusted, it can obtain the l Water Paper of forming.
The utility model structure is simple, easy to use, solves the problems, such as the quantitative unevenness of paper or so, while independent suction Water tank solves the problems, such as that negative pressure is consistent in cylinder mould machine cylinder mould machine cylinder mould, keeps paper even closer, improves the product of paper Matter.
