Technical Field

[0002] In the papermaking process, the paper fibers and fillers in the pulp are hydrophobic and tend to flocculate, which often makes it difficult to produce paper with uniform performance and strength that meets the requirements. An additive needs to be added to increase the viscosity of the pulp to facilitate the uniform dispersion of the fibers and fillers, so that the paper is uniform, smooth, flexible and has no holes, and the papermaking performance is stable. It is not easy to break the paper and generate powder during papermaking. At the same time, it can improve the tensile force and dry and wet strength of the paper and save pulp. The added additive is called a papermaking dispersant. There are many kinds of papermaking dispersants, mainly carboxylate dispersants such as LBD-1 dispersant, starch modification, etc. In the preparation process of papermaking dispersants, the raw materials need to be quantitatively proportioned. Traditional batching technology is manual quantitative addition, which is inefficient. Utility Model Content

The output end of each driving motor 16 is respectively connected to a screw rod 17, and the end of each screw rod 17 is rotatably connected to a support plate, and the support plate is vertically fixed to the top wall of the feeding pipe 2.
