Online weighing and filling machine and filling method

Abstract

The invention discloses an online weighing and filling machine and a filling method. The online weighing and filling machine comprises a to-be-filled empty box conveyer, a main filling area, a box transition conveyer, a weighing supplementary filling area and a filled box conveyer. A box support plate corresponding to and matched with the to-be-filled empty box conveyer is arranged in the main filling area. A main filling machine is arranged above the box support plate. Boxes filled by the main filling machine are conveyed onto the box transition conveyer. Weighing modules corresponding to andmatched with the box transition conveyer are arranged in the weighing supplementary filling area. A supplementary filling machine is arranged above the weighing modules and supplements materials in real time according to the weighing conditions of the weighing modules. The boxes supplemented and filled by the supplementary filling machine are conveyed to the filled box conveyer. According to theonline weighing and filling machine and the filling method, a two-time filling mode is adopted, in addition, before secondary supplementary filling, the boxes are weighed independently through the mutually separated weighing modules and are then supplemented correspondingly according to the real-time weighing conditions, and filling precision is higher.

Description

technical field [0001] The invention belongs to the technical field of material filling, and in particular relates to an online weighing filling machine and a filling method. Background technique [0002] In the existing material filling production process, the pre-quantitative filling method is usually used, that is, the filling volume is determined before the material filling, and the quantitative filling is carried out according to the previously adjusted filling volume during the filling process. . The existing filling method can meet the production process with low filling precision requirements, but for the production process with high filling precision requirements, it is easy to cause the problem that the filling volume is not accurate enough, and for the filling of some complex materials, such as Due to the inherent characteristics of the filling material, that is, the filling material is in a solid-liquid mixed and uneven state, the filling of hot pot bottom mater...

Problems solved by technology

The existing filling method can meet the production process with low filling precision requirements, but for the production process with high filling precision requirements, it is easy to cause the problem that the filling volume is not accurate enough, and for the filling of some complex materials, such as Due to the inherent characteristics of the filling material, that is, the filling material is in a solid-liquid mixed and uneven state, the filling of hot pot bottom material on the market is easy to cause filling problems due to the difference in density of the solid-liquid mixture material during the filling process. The accuracy of the amount is extremely low, which cannot meet the production requirements of accurate metering and filling, and seriously affects the final product quality
