In the present embodiment, the single-part stationery 21 that is drawn separately by described the first nip rolls group 41, the second nip rolls group 42 and the 3rd nip rolls group 43 converges to be overlapped into laminated paper 30 at superimposed roller 50 places.
(4) according to different product demands, described laminated paper 30 is carried out rear processing.
In the present invention, can come described laminated paper 30 is carried out rear processing according to different production demands.For example, when needs are produced the laminated paper paper handkerchief, can cut to form a plurality of laminated paper paper handkerchiefs unit to described laminated paper 30 according to predetermined length, afterwards again to described laminated paper paper handkerchief unit fold, packaging and other steps to be to form the laminated paper paper handkerchief.
In traditional laminated paper production technology, the paper machine is copied paper, after just volume forms the single-part stationery paper roll, is needed form the laminated paper paper roll through the rewinding process finishing, afterwards after the laminated paper paper roll carried out uncoiling carrying out processing to form the paper for daily use product.That is to say that in traditional laminated paper production technology, first being processed after laminated paper enters need to be carried out a plurality of single-part stationery paper rolls first rewinding and be formed the laminated paper paper roll, the laminated paper paper roll is carried out afterwards uncoiling again and forms laminated paper to carry out rear processing.Usually, in traditional laminated paper production technology, the rewinding process is mainly finished three tasks: one, excision body paper burr; Its two, the view picture body paper is cut into some body paper that machine table is produced fabric width that meet; Its three, the coil diameter of control rewinding paper roll makes it to meet the specification that rear machine table is produced.Yet, in traditional laminated paper production technology, it has ignored the impact of rewinding process on paper sheet thickness fully, in the rewinding process, the paper attenuation that under the effect of rewinding power, can be stretched, paper after the tension-thining pressurizes through the rewinding of rewind roll again, so that remaining on the state of tension-thining, paper can't return to the thickness before that stretches, had a strong impact on the thickness of paper, simultaneously, what also can be superimposed with each other because of the rewinding pressurization between each single-part stationery in the laminated paper is more closely knit, has further strengthened the thickness loss of laminated paper.
Compare with traditional technology for making daily used paper, the present invention the paper machine finish manufacture paper with pulp and form the single-part stationery paper roll after, according to the requirement of paper for daily use product to the number of plies, directly utilize draw gear to come a plurality of single-part stationery paper rolls are drawn separately, each single-part stationery that will pull out separately afterwards is laminated to each other to be formed for the laminated paper of rear processing.By such manner, above-mentioned production technology provided by the present invention has been omitted fully the manufacture paper with pulp first coil paper of rear formation of paper machine has been involved in the step of capable rewinding, the advantage of doing like this is: (1) has been omitted the rewinding step fully and directly a plurality of single-part stationery paper rolls has been drawn separately and formed laminated paper owing to laminated paper production technology provided by the present invention, like this, even paper is meeting tension-thining under the effect of tractive force in distraction procedure, but owing to there is not the rewinding pressurization, therefore the extended state of paper can not finalized the design under pressure, it is behind follow-up formation laminated paper, can also return to the state before being stretched, thereby so that paper is after entering into before the processing sections, its thickness obtains actv. to be kept; (2) common, in the paper machine is manufactured paper with pulp process, all can carry out paper wrinkling to increase the thickness of paper, paper after process is wrinkling is behind stacked formation laminated paper, each single-part stationery in the laminated paper is mutually chimeric each other by the fold of self, and in the rewinding process, also can become relatively tight under the effect that is entrenched in pressure each other of each single-part stationery, thereby cause the integral thickness of laminated paper to descend, after the present invention omits the rewinding step, each single-part stationery of traction will be mutually chimeric with relatively fluffy state respectively, like this, before the processing sections, actv. has kept the thickness of laminated paper after laminated paper enters.
Process experimental verification: in the production technology of traditional Multi-layer living paper, paper through copying paper, just the volume and the rewinding step after, after it enters before the processing sections, the thickness loss of paper is 16 ~ 25%, suppose that the gross thickness of rolling up each individual layer that unreels out by each first coil paper is 200 μ m, after passing through rewinding so, after entering before the processing sections, become 150 ~ 168 μ m by the thickness of the formed laminated paper of each single-part stationery; And use above-mentioned laminated paper production technology provided by the present invention, paper is through after directly being pulled the formation laminated paper after just rolling up, after entering before the processing sections, the thickness loss of sheet paper products is 8 ~ 15%, equally, when the gross thickness of rolling up each individual layer that unreels out by each first coil paper is 200 μ m, through production technology provided by the present invention, before processing sections, the thickness of laminated paper is 170 ~ 184um after entering for it.Provable thus, relatively with prior art in, laminated paper production technology provided by the present invention after paper enters before the processing sections, thickness that can actv. reservation paper.Compared with prior art, under identical working condition, produce the paper for daily use product of the identical number of plies, the resulting product of laminated paper production technology provided by the present invention more consolidation, more sturdy, bag Gao Genggao, more appearance arranged.Laminated paper production technology operating process simultaneously provided by the present invention reduces, and tooling cost reduces.
Understandable; in common paper production; the manufacturing paper with pulp of single-part stationery, just volume all belongs to papermaking front end operation; and also often can sell as product separately through the single-part stationery paper roll that obtains after just rolling up; therefore; in the production technology of laminated paper provided by the present invention, the manufacturing paper with pulp and just roll up step and can omit of single-part stationery, and directly the initial feed that the first single-part stationery paper roll of volume is used as laminated paper production technology provided by the present invention has been finished in use.That is to say, can directly draw respectively to form the laminated paper of non-reeling condition to a plurality of single-part stationery paper rolls, then direct laminated paper to this non-reeling condition carries out rear processing.
Certainly, because laminated paper production technology provided by the present invention does not have the rewinding step, therefore, according to different need of productions, can in the process that each single-part stationery 21 is drawn, excise the steps such as burr to individual single-part stationery 21.
Understandable, according to different needs, through after the above-mentioned steps provided by the present invention, the laminated paper of described non-reeling condition can be for the production of laminated paper products such as paper in reel, paper handkerchiefs.
