Description

Coating moisturizing device

Technical Field

The utility model relates to the technical field of coating water replenishing, in particular to a coating water replenishing device.

Background

The papermaking process generally comprises the following main links: 1. pulping: raw material selection, fiber separation by stewing, washing, bleaching, washing and screening, concentration or pulp sheet making and storage for standby; 2. papermaking section: dispersing pulp, removing impurities, refining pulp, pulping, preparing various additives, mixing paper materials, streaming the paper materials, head box, press part, drying part, surface sizing, drying, calendaring and coiling to form paper; 3. coating section: coating base paper, coating by a coating machine, drying, coiling, rewinding and supercalendering; 4. the processing section comprises the following steps: rewinding, cutting a flat plate (or a winding drum), sorting and packaging, and warehousing.

The moisture content of the paper has great influence on printing, the moisture is too low, the paper is brittle, and static electricity is easy to generate in printing; too high a content will make the ink difficult to dry. The moisture change has great influence on various characteristics of paper, and along with the change of the moisture, the quantitative, tensile strength, flexibility, folding endurance and the like of the paper are changed, the paper size is stretched, and even the phenomena of curling, edge curling, wrinkling, lotus leaf edges and the like are generated. In the coating process of a paper coater, water replenishment is generally required before the coating is applied. The water replenishing system used in the coating process of the existing paper coating machine is generally a roll shaft water replenishing device and is used for replenishing water to paper before coating of the coating machine. Such roll-shaft moisturizing devices generally include a water tank and a roll shaft, with the lower portion of the roll shaft directly contacting the water in the water tank so that the roll shaft remains wet. The upper portion of the roller directly contacts the lower surface of the sheet to be coated, and the roller rotates to bring water from the water tank to the surface of the sheet to replenish the sheet with water. However, the disadvantage of this roller shaft device is that: 1. only slightly attaching some moisture to the surface of the paper, the moisture does not penetrate into the paper in a short time, and the moisture is only attached to the surface of the paper; 2. the roller shaft for supplementing water is far away from the gluing distance in the next procedure, so that the water adhered to the surface of the paper is seriously lost in the high-speed running process of the paper, one part of the water is lost due to volatilization, and the other part of the water drops due to the reduction of adhesive force in the transmission process. After the paper reaches a coating station and hot gluing is carried out, the moisture content in the paper is further reduced, so that the paper becomes brittle, curls and the adhesive force of the paper is reduced in the subsequent printing and slitting section. In addition, the water content of different paper in national standard has different numerical ranges and reference values, for example, the coated paper is GB/T10335.1-2005, the delivery water content is 4% -7%, and the reference value is 5.5%. Writing paper is GB/T12654-2018, delivery moisture content is 4% -8%, and reference value is 6%. The thermosensitive paper is GB/T28210-2011, the delivery moisture content is less than 10%, and the water supplementing system used in the existing papermaking process is difficult to meet the national standard requirements when supplementing water to the paper through a roll shaft.

In view of this, according to the search, chinese patent application proposes a water replenishing system (publication No. CN 212052112U) for coating a paper coater, which sprays high-temperature water vapor on the lower surface of paper to make water quickly permeate into the paper for replenishing and controls the water replenishing amount by controlling the flow, but generally the water content of the paper is inversely proportional to the temperature, and the water replenishing of the paper is affected by the high-temperature water vapor, and thus the water replenishing of the paper is affected, and the high-temperature water vapor also causes thermal pollution to the environment, and secondly, water replenishing is performed by spraying water vapor on one side, which is not only inefficient but also not uniform.
