Precise macromolecule adding device

Abstract

The invention relates to the field of preparation of disposable hygienic products, in particular to an accurate macromolecule adding device which comprises a storage hopper and a blowing pipe barrel communicating with the storage hopper, the blowing pipe barrel comprises a blowing pipe, a feeding pipe and a compressed air pipe, the blowing pipe is horizontally arranged, the outlet end of the blowing pipe is connected with a plurality of discharging pipes which are horizontally arranged in parallel, the free ends of the discharging pipes are gradually reduced to form discharging ports, the discharging pipes incline downwards to enable the discharging ports to be arranged in a high-low staggered mode, and the feeding pipe is arranged at the inlet end of the blowing pipe and communicates with the storage hopper. The included angle between the feeding pipe and the blowing pipe is 110-160 degrees, and the compressed air pipe is arranged at the inlet end of the blowing pipe and is coaxial with the blowing pipe. The device is reasonable in structure, high polymer materials can be effectively and uniformly mixed with cotton pulp/wood pulp before a core body is formed, and the yield of disposable hygienic products is increased.

Description

technical field [0001] The invention relates to the field of preparation of disposable sanitary products, in particular to a polymer precision adding device. Background technique [0002] At present, in the field of disposable hygiene products, the common absorbent core system is as follows: use wood pulp paper to be pulverized by a pulverizer, mix it with polymers in the forming chamber, and absorb it on the forming template through high-pressure suction to form a cotton core. Blow air onto the wick underlying material. At present, the cotton core is mixed with wood paddle and SAP. When the SAP absorbs liquid, the core will swell locally, and the expanded core will form agglomerates, and the local weight will increase. When the wearer walks, the core will swing with the limbs. The agglomerated core is easy to shift, causing fault dispersion and other phenomena in the core, which affects the performance of the product. [0003] Therefore, the applicant's prior patent 20172...

Problems solved by technology

[0004] However, during the molding process of the absorbent core, the wood pulp is pulverized at high speed and blown into the mixing chamber from the pipeline. The negative pressure of the mechanism is instantly absorbed in the cotton core templates of the mold wheel mechanism. The time for uniform mixing of wood pulp and polymer materials in the mixing chamber is short, which makes it uneven when mixed with wood pulp, resulting in The absorbent core of disposable sanitary products is unevenly diverted during use, and the phenomenon of fluid accumulation, agglomeration, breakage and layering occurs, which seriously affects the secondary absorption of disposable sanitary products and reduces the cost of disposable sanitary products. quality
