Abstract
The utility model relates to pulp technology for making paper, and particularly relate to a kind of air-cushion type slewing rollers, its structure comprises the roller of hollow, the surface of roller offers several pores, the surface coverage of roller has one deck air cushion, and air cushion is provided with several perforates, and perforate is communicated with pore; One end of roller connects air inlet pipe, and air inlet pipe is connected with blower fan.Compared with prior art, paper, through air-cushion type slewing rollers, makes glue fully infiltrate in paper, and the blow gas pressure of air cushion can assist shaping at paper of glue, avoid glue be bonded on cylinder face when paper enters cylinder dried and cause the pollution to paper, and then ensure that the cleanliness factor of paper.
Description
Technical field
The utility model relates to pulp technology for making paper, particularly relates to a kind of air-cushion type slewing rollers.
Background technology
Along with the raising of people's living standard, the quality requirement of people to the wrapping paper of articles for use is more and more higher, and paper is totally one of them very important index, and it badly influences the quality of packages printing and the outward appearance of packing box itself.Therefore, the clean degree how improving paper is a very important link in paper technology.
In paper technology, top sizing covers one deck glue on paper, and the sizing material just after applying glue also rests on paper surface, and effectively do not penetrate in paper and go, therefore the adhesion of glue and paper is also not strong.Traditional method is, paper can enter drying cylinder at once and carry out drying after top sizing, so just cause the part sizing material not strong with paper adhesion to be bonded on the cylinder face of drying cylinder, when then this sizing material adheres to paper again, just define dirty point, thus have a strong impact on the cleanliness factor of paper.
Summary of the invention
The purpose of this utility model is avoid weak point of the prior art and provide a kind of air-cushion type slewing rollers, and these air cushion slewing rollers contribute to the shaping of glue and paper, improves the cleanliness factor of paper.
The purpose of this utility model is achieved through the following technical solutions:
There is provided a kind of air-cushion type slewing rollers, comprise the roller of hollow, the surface of described roller offers several pores, and the surface coverage of described roller has one deck air cushion, and described air cushion is provided with several perforates, and described perforate is communicated with described pore;
One end of described roller connects air inlet pipe, and described air inlet pipe is connected with blower fan.
Wherein, described air cushion is set to the air cushion of sheet.
Wherein, described air cushion is aluminium flake.
Wherein, several perforates described setting in column and be distributed in the surface of described air cushion equably.
Wherein, described blower fan is frequency conversion fan.
the beneficial effects of the utility model:
Air-cushion type slewing rollers of the present utility model, comprise the roller of hollow, and the surface of roller offers several pores, and the surface coverage of roller has one deck air cushion, and air cushion is provided with several perforates, and perforate is communicated with pore; One end of roller connects air inlet pipe, and air inlet pipe is connected with blower fan.During work, paper web is after sizing applicator top sizing, first pass through this air-cushion type slewing rollers, and then enter drying cylinder and carry out drying, now blower fan is blown in the roller of air cushion slewing rollers by air inlet pipe, paper is at the air cushion through air cushion turning roll surface, because the perforate of gas by air cushion surface blows out, paper is not contacted with roll surface, and make to maintain a certain distance between paper and air cushion, thus keep the tension force of paper, so just give glue and fully infiltrate into time in paper, and the blow gas pressure of air cushion can assist shaping at paper of glue, avoid glue be like this bonded on cylinder face when paper enters cylinder dried and cause the pollution to paper, and then ensure that the cleanliness factor of paper.
Accompanying drawing explanation
Utilize accompanying drawing to be described further the utility model, but the content in accompanying drawing is not formed any restriction of the present utility model.
Fig. 1 is the structural representation of air-cushion type slewing rollers of the present utility model.
Reference numeral:
Roller 1;
Air cushion 2;
Perforate 3;
Blower fan 4.
Detailed description of the invention
With the following Examples and accompanying drawing the utility model is described in further detail.
Air-cushion type slewing rollers of the present utility model, as shown in Figure 1, comprise the roller 1 of hollow, the surface of roller 1 offers several pores, the surface coverage of roller 1 has one deck air cushion 2, and air cushion 2 is provided with several perforates 3, and perforate 3 is communicated with pore, one end of roller 1 connects air inlet pipe 3, and air inlet pipe 3 is connected with blower fan 4.
During work, paper web is after sizing applicator top sizing, first pass through this air cushion 2 formula slewing rollers, and then enter drying cylinder and carry out drying, now blower fan 4 is blown in the roller 1 of air cushion 2 slewing rollers by air inlet pipe 3, paper is when the air cushion 2 of air cushion 2 turning roll surface, because the perforate 3 of gas by air cushion 2 surface blows out, paper is not contacted with roll surface, and make to maintain a certain distance between paper and air cushion 2, thus keep the tension force of paper, so just give glue and fully infiltrate into time in paper, and the blow gas pressure of air cushion 2 can assist shaping at paper of glue, avoid glue be like this bonded on cylinder face when paper enters cylinder dried and cause the pollution to paper, and then ensure that the cleanliness factor of paper.
Concrete, air cushion 2 is set to the air cushion 2 of sheet, is fitted in better on the surface of roller 1 to make air cushion 2.
Concrete, air cushion 2 is set to aluminium flake, in order to dispel the heat better, is gone out by the heat conduction on roller 1 surface.
Concrete, several perforates 3 setting in column and be distributed in the surface of air cushion 2 equably, to make circumferentially to form stable blast at roller 1, keeps the tension force of paper, contributes to shaping at paper of glue.
Concrete, blower fan 4 is frequency conversion fan 4, thus can automatically regulate the electric machine frequency of frequency conversion fan 4 automatically to regulate blast size, and the distance controlled between paper and air cushion 2 is 10 ~ 15mm.If distance is too near, paper is easily encountered air cushion 2 formula slewing rollers and breaks, and if the distance is too far, and paper easily wafts, and is unfavorable for the shaping of glue.
Finally should be noted that; the restriction of above embodiment only for illustration of the technical solution of the utility model but not to the utility model protection domain; although be explained in detail the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
