Description

Background technique

Most items appear in bottles or bags, which is convenient for storage, transportation and use. The original canning method was through manual canning. When filling, people need to add or adjust the amount of material multiple times to make it as close as possible to the standard can. It is obvious that there are many shortcomings in manual canning, for example: canned Inefficient, high production costs, not suitable for large-scale production, low canning accuracy.

Later, there was a weighing canned meter that was metered by an electronic scale. The canning method can meet the standard of the weight of each canned material, but there are many materials with irregular shapes, for example, pickles. Materials, granular Chinese patent medicines, etc. Therefore, the same weight of the same irregular material may have a large difference in its volume. In real life, articles of the same standard often need approximately the same amount in volume. In order to indicate the same standard, it is difficult to meet the canning requirements by simply weighing the cans; and, in the prior art, the canning is achieved by the volumetric method, for example, by using a single horizontal turntable. The scraper plate is installed on the surface of the turntable. When the can is installed, the excess material at the cup mouth is peeled off, and some are passed through the inclined turntable type; for the same volume of the same irregular material, the weight is also quite different.
