Description
Technical Field
The utility model belongs to the technical field of papermaking, and particularly discloses a scraper for producing paper.
Background
In the production process of toilet paper, the correct wrinkling process is the key for feeding high-grade toilet paper. Creping is the peeling of a sheet against the surface of a dryer, with the sheet slightly curling to create a crepe. It is the effect of creping that gives the tissue paper its good hand and softness, which is also different from normal tissue paper. Thus, the creping process has a significant impact on the softness and feel of the toilet paper.
In the process of producing creped toilet paper, the creping process is realized by the fact that a scraper blade on a paper machine frame is abutted against a paper sheet on a drying cylinder through a weighted lever by the edge of the scraper blade through the rotation of the drying cylinder. When the edge of the scraper blade rubs against the surface of the drying cylinder to be blunted, the paper veins of the paper sheet become thick, the paper sheet becomes soft and poor, and even the paper sheet is broken because local wrinkling cannot occur, so that the scraper blade generally needs to be detached after being used for a period of time, and can be continuously used after the edge of the scraper blade is ground flat by a knife grinder; at present, the crimping tool rest frames are connected and fixed into a whole through a stud, the crimping tool rest frames need to be stopped and adjusted by means of tools, the adjustment work is very inconvenient, the production efficiency is influenced, and the labor cost is increased.
Disclosure of Invention
The utility model aims to provide a scraper for producing paper, which aims to solve the problems of low production efficiency and inconvenient operation caused by the fact that the scraper needs to be polished after being used for a period of time in the production and processing of a wrinkling process of toilet paper.
