Disclosure of Invention
The invention aims to provide a base paper unwinding mechanism and a toilet paper slitting and rewinding device to overcome the defects of easy layering between base papers and unstable production process in the prior art.

a raw paper unwinding mechanism comprises an unwinding support, a raw paper roll arranged on the unwinding support and a humidifying spraying mechanism; the base paper is arranged on the base paper roll, and the humidifying spraying mechanism sprays and humidifies the unreeled base paper surface.
The invention discovers that after the original rewinding machine performs multilayer slitting rewinding of base paper, the combination between layers is poor due to different smoothness of two surfaces of paper sheets, and the paper layering is serious due to the poor combination condition between layers of each paper sheet of finished paper after the subsequent production and processing; and the poor binding property causes static electricity generated by friction between papers of different layers, thereby causing adverse effect on the production process.
The invention adds a water mist spraying device near the paper roll to spray the paper sheets in the cutting rewinding process, so as to form uniform water mist in a certain range on the paper surface, the paper sheets absorb moisture in the conveying process, so that the paper industry becomes soft, and after passing through the guide roller, a plurality of layers of paper sheets are tightly attached together. According to the invention, the spraying and humidifying mechanism is additionally arranged on the unwinding mechanism of the base paper, so that the base paper is sprayed and humidified, and static electricity generated in the whole process of slitting and rewinding the base paper is eliminated through the spraying and humidifying, thereby improving the stability of the production process. After the base paper surface is subjected to spray humidification, the base paper surface is softer, so that the interlayer combination among multiple layers of paper sheets is improved, and the combination among multiple layers of base paper is more stable.
The humidifying and spraying mechanism is provided with a plurality of nozzles which are uniformly arranged along the width direction of the base paper surface.
The arrangement distance of the nozzles is 10-20% of the width of the base paper.
The distance between the nozzle and the paper surface of the base paper is 50-150 mm.
The water spraying amount of the humidifying spraying mechanism to the base paper surface is 0.5-5% of the mass of the base paper surface.
The water content of the toilet paper product ranges from 5% to 9%.
In order to achieve a better effect, the process of the invention has requirements on the water spraying quantity and the uniformity of water spraying, and the water spraying quantity cannot be too large, otherwise, too much paper sheet is easy to absorb water on the paper surface to deform, or water drops are formed on the paper surface to cause the increase of the rewinding paper breaking waste rate; the water spraying amount is too small, the effects of softening the base paper and eliminating static electricity are not enough, and the improvement effect is not obvious.
The invention also provides a toilet paper slitting and rewinding device adopting the base paper unwinding mechanism, which comprises a paper guiding mechanism, a slitting mechanism and a rewinding mechanism, wherein the unwinding mechanism is arranged on the toilet paper slitting and rewinding device.
The toilet paper slitting and rewinding device further comprises a water content detection mechanism of the toilet paper product and a PLC, wherein the PLC is in signal connection with the humidifying spraying mechanism and the water content detection mechanism.
The number of the paper rolls and the humidifying spraying mechanisms is the same as the number of layers of toilet paper products.
The paper guiding mechanism comprises a paper guiding roller, and the multiple layers of base paper are adhered into a whole after being extruded by the paper guiding roller.
Compared with the prior art, the invention has the following advantages:
(1) by spraying and humidifying the base paper, the static electricity generated in the cutting and rewinding process is eliminated, so that the production is more stable;
(2) after the base paper is subjected to spray humidification, the interlayer bonding among multiple layers of paper sheets is improved;
(3) the spray humidification applies aerodynamics to pressurize water to the nozzles, and then the water is uniformly distributed to the traveling area of the paper by the nozzles, and the method is safe and clean.
