A new device for mixing and applying granular materials

Abstract

The invention belongs to the field of particle adsorption equipment, and specifically relates to a new type of granular material mixing and applying device, which includes a fixed panel, a large adsorption wheel and a small adsorption wheel, and a plurality of rings are evenly distributed on the large adsorption wheel for absorbing wood pulp. For the first adsorption window of fluff pulp, a plurality of second adsorption windows are evenly distributed in a ring on the small adsorption wheel; the first fan-shaped warehouse is fixed on the first shaft seat, and the arc surface of the first fan-shaped warehouse is open, and it is in line with the large The inner wall of the adsorption wheel is fitted, and the small adsorption wheel is set in the first fan-shaped chamber; the second fan-shaped chamber is fixed on the second shaft seat, and the arc surface of the second fan-shaped chamber is open and fits with the inner wall of the small adsorption wheel. The first sector chamber communicates with the first external negative pressure generator; the second sector chamber communicates with the external second negative pressure generator. The beneficial effect of the invention is that the wood pulp cotton wadding of the granular material can be equidistantly and non-uniformly and accurately distributed on the large adsorption wheel; the utilization rate of the material can be improved, the waste can be reduced, and the cost can be reduced.

Description

technical field [0001] The invention belongs to the field of particle adsorption equipment, and in particular relates to a novel device for mixing and applying granular materials. Background technique [0002] In the production process of sanitary napkin cores, in order to use materials more efficiently, reduce waste, and reduce production costs, materials must be used more accurately in specific positions. Taking polymer mixing as an example, in the production process, the polymer particles are first mixed with wood pulp fluff pulp, and then evenly adsorbed on the forming hub to form a sanitary napkin core. In the above-mentioned production process, because the mixed wood pulp fluff pulp is evenly distributed to form a sanitary napkin core, for the water-absorbing area that needs to be concentrated on the product, the content of the mixed wood pulp fluff pulp is not much different from other areas, resulting in a water-absorbing effect. The phase is not ideal, the water ab...

Problems solved by technology

In the above-mentioned production process, because the mixed wood pulp fluff pulp is evenly distributed to form a sanitary napkin core, for the water-absorbing area that needs to be concentrated on the product, the content of the mixed wood pulp fluff pulp is not much different from other areas, resulting in a water-absorbing effect. The phase is not ideal, the water absorption is low, and the water absorption is slow

And in the parts where the water absorption of the product is not large, or even the areas that do not need to absorb water, the mixed wood pulp fluff pulp is evenly absorbed, which causes unnecessary waste of materials and increases production costs. The equipment adopts a negative pressure adsorption wheel to rotate and adsorb, which cannot reach the level of uneven adsorption of wood pulp fluff pulp, that is, to form a spaced type
