[0002] At present, the conventional metering method of the large barrel filling machine used for juice and jam on the market has specification restrictions on packaging size. It cannot meet the filling requirements of 1-25L small bags and 200-250L large barrels at the same time. In addition, the accuracy of the metering instrument of the traditional large barrel filling machine cannot meet the accuracy requirements of 1-25 small bags.

[0003] Patent CN210764276U discloses an integrated filling machine suitable for large barrels or ton barrels, comprising a filling machine body and a filling barrel placement assembly. The filling machine body comprises a housing, a lifting assembly, and a filling gun assembly. The housing is fixedly connected to the ground. The housing, lifting assembly, and filling gun assembly are sequentially connected and arranged in a direction perpendicular to the ground. The filling barrel placement assembly is fixed to the ground and located between the filling gun assembly and the ground. The filling barrel placement assembly includes a primary placement area and a secondary placement area. The primary placement area is for large barrels, and the secondary placement area is for ton barrels. Although this patent can perform filling, weighing, and metering of ton barrels and large barrels, it only targets barrels of different qualities and cannot perform weighing and metering of small bags with completely different packaging types.
