Description

TECHNICAL FIELD

[0001] The present application relates to an automatic weighing and packaging system for granular materials. BACKGROUND

[0002] The laundry beads generally contain concentrated detergents, and the outer membrane is a water-soluble polymer material. The sealed packaging of laundry beads is more convenient for consumers, does not dirty hands, is not easy to spill, and is easy to clean. In addition, the unique low-foaming concentrated color-locked formula of laundry beads is easier to rinse, and only half of the water consumption of general laundry liquid is required.

[0003] The transmission process of traditional granular materials such as beads generally includes the following steps: first, transmission is performed, and then the beads are quantitatively packaged into a material part; second, the material part is packaged into a large package, and finally output.

[0004] The surface viscosity of the beads is large after completing the processing, and the beads are prone to jamming or clogging during the transmission process. In view of the characteristics, a suitable packaging system is developed to reduce adhesion, improve the degree of automation, and reduce the amount of waste products, which is the technical pursuit of the packaging system and process.

[0005] In the prior art, the material part is generally sent into a large packaging bag without weighing, so that the total weight of the large packaging bag is inaccurate. In view of the problems existing in the prior design, the present application is improved to realize automatic weighing, and the packaging bags that do not meet the weight are automatically output. Further, a new set of separation devices and a complete production line are provided. SUMMARY
