Background technique

Paper machine is the combination plant of paper making, is mainly made of stations such as streaming, molding, squeezing and dryings.It is existing Paper machine because structure of press section limitation, dehydrating amount is few, Paper Moisture is big, do not paste cylinder, falls the reasons such as paper, cannot produce simultaneously Low, Gao Dingliang body paper.

As shown in Figure 1, the press section of existing low basis weight fourdrinier wire large cylinder paper machine, including a press nips, two felt, 55-70g/m can be produced²Low basis weight body paper, how to make the paper machine that can produce low basis weight body paper and produce 75-220g/ m²Height quantify body paper, become the Main Topics and technical problem of current skilled artisan.

In summary, the existing technology has inconveniences and defects in actual use, so it is necessary to be improved.

Utility model content

The technical problems to be solved in the utility model is cannot to produce low, Gao Dingliang body paper simultaneously not for same paper machine Foot, provides a kind of press section of fourdrinier wire large cylinder paper machine, decoration structure features simple design is reasonable, can be realized 55-220g/m²Large span is not With the production of quantitatively body paper, and guarantee good dehydrating effect in paper expressing process.

The utility model uses a kind of following technical scheme: press section of fourdrinier wire large cylinder paper machine, including the second squeezing pressure Area, the second press nips front are equipped with the first press nips.

A kind of prioritization scheme, first press nips are formed by stone roll and rubber roller.

Further, the stone roll, rubber roller are separately mounted in the stud wall of the second rack, stone roll be located at rubber roller just on Side, stone roll pressurize to the rubber roller of lower section.

Further, it is smoothly transmitted between two press nips, felt preferably three.

Further, the felt includes the first felt, the second felt, third felt.

Further, first felt, for page to be sent to the first press nips；Second felt, is used for The page that first press nips come out is sent to the second press nips；The third felt, for going out the second press nips The page come is sent to drying cylinder.

Further, the position of the first felt wrapping is equipped with plain-barreled roll, and a plain-barreled roll is mounted under the second housiung separator Side, another two plain-barreled rolls are separately mounted in the first framework pillar leftward position.

Further, the plain-barreled roll preferably three.

The utility model after the above technical solution is adopted, compared with prior art, has the advantage that

1, same press section of a paper machine can produce low basis weight body paper and the high quantitative body paper of production；

2,55-220g/m can be produced²Large span quantifies body paper；

3, dehydrating effect meets production requirement；

4, the decoration structure features simple design of press section is reasonable.

The utility model is described in detail with reference to the accompanying drawings and examples.

In figure: the first felt of 1-, the second felt of 2-, 3- third felt, 4- page, 5- plain-barreled roll, 6- stone roll, 7- rubber roller, 8- First press nips, the second press nips 9-, the first rack of 10-, the second rack of 11-.

Specific embodiment

For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention Specific embodiment of the present utility model.

A kind of press section of the fourdrinier wire large cylinder paper machine of embodiment 1

As shown in Fig. 2, the utility model provides a kind of press section of fourdrinier wire large cylinder paper machine, including the first press nips 8, Second press nips 9, the first press nips 8 are located at the front of the second press nips 9；First press nips 8 are by 6 He of stone roll The formation of rubber roller 7；The stone roll 6, rubber roller 7 are separately mounted on the column of the second rack 11, and stone roll 6 is located at right above rubber roller 7, stone The rubber roller 7 of 6 pairs of lower sections of roller pressurizes；

6 material of stone roll is natural granite, and 6 surface of stone roll is smooth, can be reduced adherency, the broken end of l Water Paper page, makes roller The easily peelable l Water Paper page of face promotes l Water Paper page to complete primary dewatering；

The rubber roller 7 is encapsulated ironcasting roller, and surface is in corrugated, and has good elasticity.

To make smooth transmission of the page 4 when by the first press nips 8, felt is preferably 3, and felt is first respectively Felt 1, the second felt 2, third felt 3；

First felt 1 is set on the position of first felt 1 wrapping for page 4 to be transmitted to the first press nips 8 There is plain-barreled roll 5, plain-barreled roll 5 realizes spreading；The plain-barreled roll 5 preferably three；First plain-barreled roll 5 and second plain-barreled roll 5 are installed respectively On on the left of 10 column of the first rack, third root plain-barreled roll 5 is mounted on the lower section of 11 crossbeam of the second rack；

Second felt 2, the page 4 for coming out the first press nips 8 are transmitted to the second press nips 9；

The third felt 3, the page 4 for coming out the second press nips 9 are transmitted to drying cylinder and carry out drying and dewatering, take off The page 4 that water is completed is transported to subsequent processing.

The utility model press section is set there are two press nips, after felt preferably 3, low basis weight fourdrinier wire large cylinder paper machine The conversion from low basis weight body paper to high quantitative body paper can be completed in the paper type of production, and the paper of production is either be less than 70g/m²Paper is also possible to up to 220g/m²Paper, 55-220g/m can be produced²Large span different basis weights body paper.

The above is the citing of the utility model preferred forms, wherein the part that do not address in detail is this field The common knowledge of those of ordinary skill.The protection scope of the utility model is based on the contents of the claims, any to be based on this reality The equivalent transformation carried out with novel technical inspiration, is also within the protection scope of the utility model.
