Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a desiccant feeding device. Background Art

[0002] Desiccant refers to a substance that can remove moisture from moist substances. It is usually divided into two categories: chemical desiccants, such as calcium sulfate and calcium chloride, which dry by combining with water to form hydrates; physical desiccants, such as silica gel and activated alumina, which dry by physically adsorbing water. The above two types of desiccants should reduce the time they are exposed to the air after production and packaging to avoid excessive exposure of the desiccant processed into a single package to the air, resulting in reduced drying effect or failure during use.

[0003] The existing desiccant feeding device generally includes a vibrating material tray and a conveyor belt arranged at the output end of the vibrating material tray. In the above structure:

[0004] (1) The opening of the vibrating tray causes the desiccant packs in the tray to be exposed to the air for a long time and cause a reaction;

[0005] (2) When the desiccant package falls naturally into the packaging bag at the end of the conveyor belt, in order to ensure that the desiccant package can fall into the packaging bag accurately, limit side plates are provided on both sides of the conveyor belt. The setting of the limit side plates causes the desiccant package to get stuck with the limit side plates at the end of the conveyor belt, resulting in the desiccant package being unable to be bagged in time, increasing the time it is exposed to the air.
