Description

Moistureproof adsorption filter screen cover of powder filling head Technical Field The utility model relates to the technical field of powder filling equipment, in particular to a moistureproof adsorption filter screen cover of a powder filling head. Background The powder filling machine is used as an important material split charging device, is widely applied to industries such as medicine, food, chemical industry and the like, and is used for quantitatively filling various powdery materials (such as medicinal powder, milk powder, seasonings, additives and the like) according to set weight or volume. Common types of existing powder filling mechanisms comprise screw type filling, vacuum type filling, gravity type filling and the like, wherein a filling head is used as a key component for material output, and the filling precision and the production efficiency are directly related. However, in the practical application process, due to the influence of environmental factors such as higher environmental humidity of workshops and flying dust, adhesion and caking phenomena occur at the filling head in the powder conveying process, metering errors are caused to reduce the filling precision, materials are easy to stay, microorganisms are bred, and the mouthfeel and preservability (such as mildew) of food powder products are finally influenced. Once the blocking or adhesion phenomenon occurs, the disassembly and the cleaning are usually carried out by stopping, the cleaning procedure is complicated, the stopping time is long, and the production continuity and the overall efficiency are greatly influenced. Therefore, a need exists to design a moisture-proof adsorption filter screen cover of a powder filling head to meet the modern production and processing requirements. Disclosure of utility model The utility model aims to provide a moistureproof adsorption filter screen cover of a powder filling head, which can locally and actively dehumidify and protect the filling head, effectively prevent powder from adhering and agglomerating due to wetting at the filling head, reduce the frequency of equipment which is required to be shut down and cleaned due to blockage, further improve the continuity and stability of filling production and improve the quality and preservability of powder products.
