Quantitative canning machine for irregular materials

Abstract

Disclosed in the invention are an irregular material quantitatively filling machine and a quantitatively filling method. The irregular material quantitatively filling machine comprises a first time weighing device, a main feeding device, a second time weighing device and a compensation feeding device which are sequentially arranged along the conveying direction and controlled by a programmable controller. The main feeding device is used for constant-volume filling of irregular material to realize major filling of container, and then the compensation feeding device is used for fine-adjustment filling to realize constant-weight filling, so that filling is more precise and can effectively meet the requirements of filling standards in terms of volume and weight. Besides, in the whole filling process, the containers are conveyed by a conveying device to different stations and automatically weighed, filled etc. It has the characterization of high level automatization, hence realizing rapid filling, improving production efficiency, and being suitable for large-scale production. In addition, the structure of the whole machine is compact in arrangement, reducing the space occupied by the machine and benefiting the integral arrangement of a workshop.

Description

technical field [0001] The invention relates to the technology in the field of material canning, in particular to a quantitative filling machine for irregular materials. Background technique [0002] Most of the items appear in bottles or bags, which is convenient for storage, transportation and use. The initial canning method is through manual canning. When canning, people need to add or adjust the amount of materials many times to make it as close as possible to the standard canning volume. Obviously, there are many shortcomings in manual canning, such as: The efficiency is low, the production cost is high, it is not suitable for large-scale production, and the precision of canning is low. [0003] Later, weighed cans measured by electronic scales appeared. This canning method can meet the weight of the canned materials each time. However, there are many materials that are irregular in shape, such as pickles. Materials, granular Chinese patent medicines, etc. Therefore, ...

AI Technical Summary

Problems solved by technology

The initial canning method is through manual canning. When canning, people need to add or adjust the amount of materials many times to make it as close as possible to the standard canning volume. Obviously, there are many shortcomings in manual canning, such as: Low efficiency, high production cost, not suitable for large-scale production, low precision of canning, etc.

[0003] Later, weighed cans measured by electronic scales appeared. This canning method can meet the weight of the canned materials each time. However, there are many materials that are irregular in shape, such as pickles. Materials, granular Chinese patent medicines, etc. Therefore, the same weight of the same irregular material may have a large difference in volume. In real life, items of the same standard often require approximately the same volume. Therefore, it is difficult to meet the requirements of canning if the weighing method alone is used for canning; and, in the prior art, there is also a volumetric method to achieve canning, for example, by adopting a single horizontal turntable , install a scraper on the surface of the turntable, peel off the excess material at the mouth of the measuring cup when filling the can, and some are by tilting the turntable, etc.; for the same volume of the same irregular material, its weight is also quite different. Its canned volume is very inaccurate

[0004] For the canning of the above-mentioned irregular materials, there is no fully automatic equipment for canning and accurate canning. Therefore, this is a topic of great research value.
