[0001] The invention belongs to the technical field of paper processing, and in particular relates to an online density monitoring device for household paper. Background Art

[0002] With the advancement of science and technology, the equipment used in the production process of household paper is automated and intelligent, the regulation in the production process is more convenient, the operation of the paper machine is more stable, and the production capacity is also improved simultaneously. The automation and intelligence of the equipment have become relatively simpler than the previous production process. The production process still requires accumulated experience to judge and make adjustments. In other words, under the current conditions, the data that can be monitored by the instruments in the production of household paper is also incomplete. It is necessary to find these laws and master them in production to stabilize the production. The density and thickness of paper are the main factors affecting the use effect of paper. The density of paper depends on the density of pulp. When testing pulp in paper production, sensors are usually used to monitor the flowing pulp to collect data to prevent deviations in pulp density. Because the flowing pulp has a certain depth, the sensor monitoring the pulp has a certain error, which in turn affects the paper density and use effect of papermaking. Therefore, a new type of online density monitoring equipment for household paper is designed to change the above technical defects. Summary of the invention
