Description

Technical Field

[0001] The utility model relates to automatic quantitative flour packaging equipment, belonging to the technical field of flour production and packaging. Background Art

[0002] Packaging equipment refers to equipment that can complete all or part of the product and commodity packaging process. The packaging process includes filling, wrapping, sealing and other major processes, as well as related processes before and after, such as cleaning, stacking and disassembly. In the flour production process, packaging is the most critical step. Flour needs to be bagged in a quantitative manner to ensure that each bag of flour can be quantitatively weighed.

[0003] For example, an automatic quantitative flour packaging device with patent publication number CN202320037092.5 includes a base, a quantitative piece, a slide plate, a quantitative barrel, a cylinder and a storage barrel. The base is fixedly connected to the quantitative piece, the base is slidably connected to the slide plate, the slide plate is fixedly connected to the quantitative barrel, and a cylinder is arranged between the quantitative barrel and the slide plate.

[0004] Since the above-mentioned flour packaging equipment fills and packages flour through quantitative barrels, the flour is mostly filled in an inclined surface after being discharged and filled, which easily leads to incomplete spreading after reaching the scale line, resulting in the overall amount of flour not meeting the demand, which indirectly affects the quantitative packaging effect of flour.
