Rewinding roller structure used in toilet paper rewinding machine and rewinding method thereof

The invention provides a rewinding roller structure used in a toilet paper rewinding machine and a rewinding method thereof. The rewinding roller structure comprises an upper rewinding roller, a lower rewinding roller, a rear rewinding roller and a compression roller which are installed in sequence, wherein the compression roller has the same linear speed with the rear rewinding roller. The rewinding roller structure is characterized in that the compression roller is contacted with the rear rewinding roller in an opening and closing manner duly by the driving of a driving mechanism in the process of the rewinding of the base paper and the base paper being snapped when the upper rewinding roller speeds up. As the invention adopts the structure that the compression roller can be contacted with the rear rewinding roller in an opening and closing manner, the compression roller does not contact with the rear rewinding roller when the patterned toilet paper performs normal rewinding, thus ensuring that the patterned toilet paper is not deformed, leading the finished products thereof to possess good bulking intensity and flexibility, and ensuring good handfeel effect of users; when the upper rewinding roller performs paper snapping by speeding up, the compression roller is compressed with the rear rewinding roller duly, ensuring the accuracy and reliability of the cutting of the toilet paper and the continuity of the work; and the invention is also characterized by simple and smart structure and applicability and reliability.

Production method of lightweight paper

The invention discloses a production method of lightweight paper. The production method comprises a wood pulp proportioning step and a mixing step. Needle BCMTP chemimechanical pulp and needle bleached chemical wood pulp are proportioned and pulped; a neutral sizing agent, cationic starch, cationic polyacrylamide and talcum powder are used; then a paper manufacturing process is performed. Importedneedle wood pulp and broadleaf wood bleached sulfate pulp are respectively pulped and blended, and various additives are added; the blend is conveyed into an approaching system for dehydration forming through a wet part and then is further dehydrated through a squeezing part; after pre-drying, semi-dry calendaring and surface sizing are performed, the product is dried through a drying part; the product is baked at low temperature, subjected to soft calendaring finishing and wound. First of all, high bulkiness is achieved, and the flatness and the tensile strength of paper are not affected, sothe production method is suitable for high-speed printing; secondly, no flourescent brightener is contained; compared with common coated paper, offset paper and lightweight paper, the lightweight paper produced according to the method is relatively dark and has a color close to the primary color of wood pulp, so that visual fatigue cannot be caused by long-time reading.

Method for producing carbon-free and thermosensitive body paper by using large proportion of chemithermomechanical pulp

The invention discloses a method for producing a carbon-free and thermosensitive body paper by using large proportion of chemithermomechanical pulp, comprising the working procedures such as sizing, discharging pulp by a pulp flowing box, dewatering by a mesh part, dewatering in a squeezing way, previously drying, coating, carrying out post drying, carrying out press polish, and reeling. The raw materials used by the sizing working procedure are chemithermomechanical pulp and chemical pulp according to the proportion of (6-7.5):(3-3.5), enabling the chemithermomechanical pulp and the chemical pulp subjected to the sizing working procedure to be respectively flowed and transported to different parts of a pulp discharge working procedure of the pulp flowing box, the pulp flowing box in the pulp flowing box sizing working procedure is a three-layer pulp flowing box, the chemical pulp of the sizing working procedure is evenly distributed into an upper-layer pulp distribution system and a lower-layer pulp distribution system of the pulp flowing box, the chemithermomechanical pulp flows to a middle-layer pulp distribution system of the pulp flowing box, and the three-layer pulp flowing out of the pulp flowing box is dewatered by the mesh part. According to the method, not only can the fineness and the smoothness of the surface of a finished paper be guaranteed, but also the paper can not be faded and aged after being stored for a long term.

Drying method of traditional Chinese medicine thick paste

The invention relates to a drying method of traditional Chinese medicine thick paste. The method comprises the steps that traditional Chinese medicine extract to be dried is concentrated into thick paste with relative density of above 1.10; the thick paste is paved into a dry container whose upper part is irradiated by light wave, and the thickness is controlled to be 2mm to 5mm; the container is vacuumized until the vacuum degree is above 0.6MPa; light wave irradiation is started to heat and dry the material for 45 minutes to 180 minutes, and a dry product is obtained. In addition, electric heating or steam heating is added at a lower part, so as to dry the thick paste. Due to the fact that the adopted light wave can directly penetrate through the material, compared with a drying method which adopts electric heating or steam heating, according to the drying method of traditional Chinese medicine thick paste, the drying speed is higher, the heating uniformity is good, the defects of no easiness in microwave heating control and electromagnetic leakage are overcome, a metal structure is allowed to exist in the equipment during work, no-load heating and static heating of the equipment are allowed, particularly the auxiliary electric heating or steam method is added at the lower part, heating is carried out simultaneously up and down, the drying time is obviously shortened, and a significant effect in keeping heat sensitive components and easily oxidized components during a drying process is achieved. The operation and control are simple, and the large-scale production is suitable.
