Problems solved by technology

In actual production, after the paper is coated with slurry, it needs to be squeezed and dehydrated by pressing rollers. When the pressing roller squeezes the slurry, the slurry in the middle part of the paper will be squeezed and dispersed to both sides, resulting in the middle of the paper being formed. Part of the formation is lower than that on both sides, which affects the quality of the paper

Abstract

The invention discloses a paper forming mechanism for diverting slurry, aiming to solve the technical problem that when the paper on the forming net is extruded and dehydrated, the slurry in the middle part is squeezed and spreads to both sides, so that the evenness of the paper is deteriorated , including a feeding channel and a diversion molding assembly, the feeding channel includes a forming net and a number of feed pipes, the diversion molding component includes a first guide, a second guide and a pressure roller, the slurry is transported to the forming net and Conveying synchronously with it, the first area guides the slurry to the middle of the forming net, and after reaching the second area, it diverts the flow at the second guide to ensure the distribution of the slurry on the forming net. It is more reasonable, and when it reaches the third area, the pulp in the middle part is still more than the pulp on both sides. After being squeezed and dehydrated by the pressing roller, the paper has uniform uniformity and simple structure.

Description

technical field [0001] The invention relates to the field of papermaking machinery and equipment, in particular to a paper forming mechanism for diverting slurry. Background technique [0002] Formation, defined as the visible appearance when held against a light. Formation is actually an external manifestation of the uniformity of fibrous tissue, mainly the size, clarity and distribution of flocculation in the paper sheet. The importance of formation Paper formation is the first sensory index of people. Formation not only affects the aesthetic value of paper, but also affects the physical and optical properties of paper. It is one of the most basic and important indicators of paper quality; almost All paper quality indicators are closely related to evenness; not only that, evenness is also known as the "Miss Public Relations" for products to win the market and users; what's more, some people compare evenness to "the face of paper-making enterprises". [0003] Therefore, p...
