Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking, and in particular relates to a papermaking forming net and papermaking equipment. Background Art

[0002] As a key component of a papermaking machine, the papermaking forming mesh undertakes the important task of paper sheet forming and dehydration. According to different needs and conditions, the material and specifications of the papermaking forming mesh are also different. The commonly used papermaking forming meshes on the market include single-layer forming mesh, double-layer forming mesh, two-layer and a half forming mesh and three-layer forming mesh, among which the three-layer forming mesh is the more commonly used papermaking forming mesh in high-speed paper machines. Although the existing papermaking forming mesh can basically complete the paper sheet forming and dehydration tasks, its shortcomings are that the papermaking layer of the existing papermaking forming mesh is uneven and the fiber support index is not high, resulting in obvious mesh marks on the surface of the paper, making the fiber and filler retention rate of the paper not high, and there are shortcomings such as high water rejection and slow dehydration, which cannot meet the requirements of special paper for high-speed and low-weight packaging. Therefore, a special paper papermaking forming mesh is needed. Utility Model Content

[0006] Furthermore, the four corners of the middle-layer net are connected with docking components, and the docking components include an inner fixing part, and the inner fixing part is connected to the side of the middle-layer net. The outer wall of the inner fixing part is fixedly connected with a spring, the outer end of the spring is connected with an outer fixing part, and the outer part of the outer fixing part is fixedly connected with a collar.
