Description

One kind is used for the high-strength corrugating medium's pressing device of light basis weight

【Technical field】

A kind of paper making equipment is the utility model is related to, it is especially a kind of to be used for the high-strength corrugating medium's pressing device of light basis weight.

【Background technology】

Currently, traditional paper industry is moving towards low-carbon, environmental protection, the road of Green Development.Have benefited from industrial goods packaging and Express Logistics industry is fast-developing, package paper and board product sustainable growth, in order to effectively improve production efficiency and product quality, Energy consumption and supplies consumption are reduced, controls CO2 emission, enterprise inside the circle is for the high-strength corrugating medium's production technology of light basis weight Research and development never stop.

For using wastepaper as raw material production light basis weight high-strength corrugating medium, it is maximum the problem of be that adhesion is poor between fiber, paper Page low intensity, l Water Paper page transmittance process easily break paper, cause the reduction of paper machine production efficiency, and energy consumption cost is high.Existing production corrugation The press section of a paper machine of core paper uses suction press+blind drilled press more, and when producing light basis weight corrugating medium, press section failure is more, Web dryness can not effectively improve, and l Water Paper page paper injection is difficult, and page produces more paper defects in press section, such as broken end, gives a discount, embossing Deng.The corrugated paper machine of some production light basis weight products is used unipress+big roll-in instead and squeezed, but big roll-in is squeezed for wet web dryness The effect of raising is limited, it is impossible to gives full play to the effect that big roll-in is squeezed, the comprehensive benefit of acquirement can not offset input power consumption And operating cost, cause energy consumption cost still higher.

【Utility model content】

The technical problems to be solved in the utility model be to provide simple in construction, production efficiency is high, the one of stable and reliable operation Kind is used for the high-strength corrugating medium's pressing device of light basis weight.

What the purpose of this utility model was realized in：

One kind is used for the high-strength corrugating medium's pressing device of light basis weight, including the first pressure roller, vacuum pressure roller, center stone roll and the Two pressure rollers, first pressure roller and the vacuum pressure roller are tangent and the first pressed zone is formed at point of contact, the vacuum pressure roller with The center stone roll is tangent and the second pressed zone is formed at point of contact, and the center stone roll is tangent with second pressure roller and is cutting Point place the 3rd pressed zone of formation, on first pressure roller, vacuum pressure roller and the second pressure roller rotating around provided with the first woollen blanket, second mao Blanket and the 3rd woollen blanket, first woollen blanket and first pressure roller are tangential at first pressed zone, second woollen blanket with The vacuum pressure roller is tangential at the first pressed zone and the second pressed zone, and the 3rd woollen blanket is tangential on institute with second pressure roller State at the 3rd pressed zone.

One kind as described above is used for the high-strength corrugating medium's pressing device of light basis weight, first pressure roller and the vacuum pressure Have angle α between the line of centres of roller and the line of centres of the vacuum pressure roller and the center stone roll, and α be 114 °- 118°。

One kind as described above is used for the high-strength corrugating medium's pressing device of light basis weight, the vacuum pressure roller and the middle cardiolith Have angle β between the line of centres of roller and the line of centres of the center stone roll and second pressure roller, and β be 138 °- 142°。

Compared with prior art, the utility model has the following advantages that：

1st, the utility model is cancelled big roll-in and squeezed, in press section of a paper machine independently using the first pressure roller, vacuum pressure roller, middle cardiolith The four-roller three that roller and the second pressure roller are formed presses unipress, simplifies structure of press section, improves paper injection efficiency, reduces press section power Consumption；

2nd, the layout structure of Curve guide impeller pressure roller, optimization l Water Paper page enter nip angle and outgoing nip peel angle, realize three The stable squeezing of individual pressed zone, ensure to squeeze out the stability of the mass dryness fraction of page；

3rd, the characteristics of being adapted to production light basis weight high-strength corrugating medium, realize that pressed zone is symmetrically squeezed, it is poor to reduce page two sides, Smooth transmission of the l Water Paper page in each pressed zone is realized, improves the efficiency and product quality of pressed zone.

【Brief description of the drawings】

Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, wherein：

Fig. 1 is structural representation of the present utility model.

【Embodiment】

One kind is used for the high-strength corrugating medium's pressing device of light basis weight, including the first pressure roller 1, vacuum pressure roller 2, center stone roll 3 With the second pressure roller 4, the first pressure roller 1 is tangent with vacuum pressure roller 2 and the first pressed zone 5, vacuum pressure roller 2 and center are formed at point of contact Stone roll 3 is tangent and the second pressed zone 6 is formed at point of contact, 3 and second pressure roller of center stone roll, the 4 tangent and formation the 3rd at point of contact Pressed zone 7, rotating around provided with the first woollen blanket 8, the second woollen blanket 9 and the 3rd mao on the first pressure roller 1, the pressure roller 4 of vacuum pressure roller 2 and second Blanket 10, the first woollen blanket 8 and the first pressure roller 1 are tangential at the first pressed zone 5, and the second woollen blanket 9 is tangential on the first pressure with vacuum pressure roller 2 Squeeze at the pressed zone 6 of area 5 and second, the 3rd woollen blanket 10 and the second pressure roller 4 are tangential at the 3rd pressed zone 7.

Between first pressure roller 1 and the line of centres and the line of centres of vacuum pressure roller 2 and center stone roll 3 of vacuum pressure roller 2 into One angle α, and α is 114 ° -118 °.

Between the line of centres of the pressure roller 4 of the line of centres and center stone roll 3 and second of vacuum pressure roller 2 and center stone roll 3 into One angle β, and β is 138 ° -142 °.

The utility model enters the first pressed zone 5 in use, l Water Paper page adsorbs in the second woollen blanket 9 times through vacuum pressure roller 2, wet Page is squeezed by the first woollen blanket 8 and the second woollen blanket 9 in the first pressed zone 5 and carries out double dewatering.L Water Paper page is due to vacuum pressure roller 2 Suction-operated under and drive and lower be further dehydrated into the second pressed zone 6.Due between l Water Paper page and the second woollen blanket 9 Surface tension be less than its surface tension between center stone roll 3, leave l Water Paper page and the second woollen blanket 9 behind the second pressed zone 6 Separation, and continue to be dehydrated as center stone roll 3 enters the 3rd pressed zone 7.Now the mass dryness fraction of l Water Paper page obtains larger raising, with After the sur-face peeling of cardiolith roller 3, attracted by paper web stabilizer lower into follow-up drying section.
