In the present embodiment, manufacture paper with pulp in process at described single-part stationery 10, include and wrinkling step is carried out to paper, to make the single-part stationery 10 of manufacturing paper with pulp out, there is chill mark structure.
Understandable, in the present invention, the papermaking process not specific requirement of described single-part stationery 10, existing papermaking process can use, and has the single-part stationery 10 of chill mark structure as long as can manufacture paper with pulp out.
(2) described single-part stationery 10 is reeled to form single-part stationery paper roll 20;
Usually, manufacturing paper with pulp and reeling of paper belongs to two different operations of same paper machine, therefore, in the ordinary course of things, in the present embodiment, described single-part stationery 10 manufacture paper with pulp and winding steps completes in same paper machine.
Certainly, in the present invention, for the restriction that the equipment of manufacturing paper with pulp and reeling of single-part stationery 10 is not special, existing papermaking process and winding apparatus can use, and form described single-part stationery paper roll 20 as long as final.
(3) according to the predetermined number of plies, separately traction is carried out to unreel out multiple separate single-part stationeries 21 at least two described single-part stationery paper rolls 20, and the laminated paper 30 of the mutual stacked formation non-rolling state of each single-part stationery 21 that will pull out separately.
In the present embodiment, the number of described single-part stationery paper roll 20 is three, uses nip rolls group 40 to draw separately described three single-part stationery paper rolls 20.Corresponding with described three single-part stationery paper rolls 20, described nip rolls group 40 comprises the first nip rolls group 41, second nip rolls group 42 and the 3rd nip rolls group 43, and each nip rolls group is corresponding for drawing to form single-part stationery 21 to it with a single-part stationery paper roll 20.
Preferably, in the present embodiment, described first nip rolls group 41, second nip rolls group 42 and the 3rd nip rolls group 43 have included guiding roller, extension roller and idler roller, wherein, described guiding roller is used for leading to single-part stationery 10, described extension roller is used for paper stretch is opened, the degree of tension that described idler roller keeps certain for making paper.
Preferably, the haulage speed of described first nip rolls group 41, second nip rolls group 42 and the 3rd nip rolls group 43 is identical.
In the present embodiment, the single-part stationery 21 drawn separately by described first nip rolls group 41, second nip rolls group 42 and the 3rd nip rolls group 43 converges at superimposed roller 50 to be overlapped into laminated paper 30.
(4) according to different product demands, aft-loaded airfoil is carried out to described laminated paper 30.
In the present invention, aft-loaded airfoil can be carried out according to different production demands to described laminated paper 30.Such as, when laminated paper paper handkerchief produced by needs, can cut to form multiple laminated paper paper handkerchief unit to described laminated paper 30 according to predetermined length, more described laminated paper paper handkerchief unit be folded afterwards, packaging and other steps to be to form laminated paper paper handkerchief.
In traditional laminated paper production technology, paper machine, after completing copy paper, just volume forms single-part stationery paper roll, needs through rewinding process to form laminated paper paper roll, carries out aft-loaded airfoil to form paper for daily use product laminated paper paper roll being carried out uncoiling afterwards.That is, in traditional laminated paper production technology, before laminated paper enters aft-loaded airfoil, need multiple single-part stationery paper roll first to be carried out rewinding and form laminated paper paper roll, again laminated paper paper roll is carried out uncoiling afterwards and form laminated paper to carry out aft-loaded airfoil.Generally, in traditional laminated paper production technology, rewinding process mainly completes three tasks: one, excision body paper burr; Its two, view picture body paper is cut into some machine tables that meets and produces the body paper of fabric width; Its three, control the coil diameter of rewinding paper roll, make it to meet the specification that aft-loaded airfoil board is produced.But, in traditional laminated paper production technology, it ignores the impact of rewinding process on paper sheet thickness completely, in rewinding process, paper can be stretched thinning under the effect of winding force, paper after tension-thining pressurizes through the rewinding of rewind roll again, paper is made to remain on the state of tension-thining and the thickness before cannot stretching being returned to, have a strong impact on the thickness of paper, simultaneously, what also can be superimposed with each other because of rewinding pressurization between each single-part stationery in laminated paper is more closely knit, further increases the thickness loss of laminated paper.
Compared with traditional technology for making daily used paper, the present invention completes at paper machine and to manufacture paper with pulp and after forming single-part stationery paper roll, according to the requirement of paper for daily use product to the number of plies, directly utilize draw gear to draw separately multiple single-part stationery paper roll, afterwards each single-part stationery pulled out separately is laminated to each other to be formed the laminated paper being used for aft-loaded airfoil.By such manner, the first coil paper formed after above-mentioned production technology provided by the present invention eliminates manufacture paper with pulp to paper machine completely involves in the step of row rewinding, the advantage done like this is: multiple single-part stationery paper roll directly draws separately because laminated paper production technology provided by the present invention eliminates rewinding step completely and forms laminated paper by (1), like this, even if paper is meeting tension-thining under the effect of tractive force in distraction procedure, but pressurize owing to there is no rewinding, therefore the extended state of paper can not be shaped under pressure, it is after follow-up formation laminated paper, the state before being stretched can also be returned to, thus make paper before entering into aft-loaded airfoil section, its thickness obtains actv. and retains, (2) usual, all can carry out wrinkling with the thickness increasing paper in process manufactured paper with pulp by paper machine to paper, paper after wrinkling is after stacked formation laminated paper, each single-part stationery in laminated paper is fitted together to each other mutually by the fold of self, and in rewinding process, each other chimeric of each single-part stationery also can become relative close under the effect of the pressure, thus cause the integral thickness of laminated paper to decline, after the present invention omits rewinding step, the each single-part stationery drawn respectively will be fitted together to mutually with relatively fluffy state, like this, before laminated paper enters aft-loaded airfoil section, actv. remains the thickness of laminated paper.
Through experimental verification: in the production technology of traditional Multi-layer living paper, paper is after copy paper, just volume and rewinding step, before it enters aft-loaded airfoil section, the thickness loss of paper is 16 ~ 25%, suppose that the gross thickness of rolling up each individual layer unreeling out by each just coil paper is 200 μm, so after rewinding, after entering before processing sections, the thickness of the laminated paper formed from each single-part stationery becomes 150 ~ 168 μm; And use above-mentioned laminated paper production technology provided by the present invention, after paper is directly pulled and forms laminated paper after just rolling up, after entering before processing sections, the thickness loss of sheet paper products is 8 ~ 15%, equally, when the gross thickness of rolling up each individual layer unreeling out by each just coil paper is 200 μm, through production technology provided by the present invention, it is after entering before processing sections, and the thickness of laminated paper is 170 ~ 184um.Provable thus, relatively with prior art, laminated paper production technology provided by the present invention, can the thickness of actv. reservation paper before paper enters aft-loaded airfoil section.Compared with prior art, under identical working condition, produce the paper for daily use product of the identical number of plies, the product that laminated paper production technology provided by the present invention obtains more consolidation, more sturdy, bag Gao Genggao, more have appearance.Laminated paper production technology operating process provided by the present invention reduces simultaneously, and tooling cost reduces.
Understandable; in common paper production; the manufacturing paper with pulp of single-part stationery, just volume all belong to papermaking front end operation; and the single-part stationery paper roll obtained after just rolling up also often can be sold as product separately; therefore; in the production technology of laminated paper provided by the present invention, manufacturing paper with pulp and just rolling up step of single-part stationery can be omitted, and directly use has completed the initial feed that the single-part stationery paper roll just rolled up is used as laminated paper production technology provided by the present invention.That is, directly can draw to multiple single-part stationery paper roll the laminated paper forming non-rolling state respectively, then the direct laminated paper to this non-rolling state carries out aft-loaded airfoil.
Certainly, because laminated paper production technology provided by the present invention does not have rewinding step, therefore, according to different need of productions, in the process that each single-part stationery 21 is drawn, the steps such as excision burr can be carried out to individual single-part stationery 21.
Understandable, according to different needs, after above-mentioned steps provided by the present invention, the laminated paper of described non-rolling state may be used for producing the laminated paper such as paper in reel, paper handkerchief product.
Present invention also offers a kind of laminated paper using above-mentioned laminated paper production technology to produce, it is laminated by least two-layer single-part stationery, compared with the gross thickness of described at least two-layer single-part stationery before the described laminated paper of stacked formation, the gross thickness loss of described at least two-layer single-part stationery after the described laminated paper of stacked formation is 8 ~ 15%.
In addition, those skilled in the art also can do other change in spirit of the present invention.Therefore these changes done according to the present invention's spirit, all should be included within the present invention's scope required for protection.
