The automatic weighing and packaging device comprises a supporting part, and an isolation hood is arranged at the upper end of the supporting part; a protective door is arranged on the isolation hood, a feeding device is arranged at the upper end of the supporting part, the protective door close to the feeding device is the input end, and a weighing device, a carrying mechanical arm, an automatic vacuum plastic packaging device and a conveying device are further arranged in the isolation hood; the conveying device is sequentially provided with an automatic vacuum plastic packaging device, a marking and labeling machine and a visual proofreading device from the input end to the output end, the labeling machine is externally connected with an alarm device, and gross weight electronic scales fixed to the supporting part are arranged on the two sides of the marking and labeling machine correspondingly; and a precision electronic scale, the visual proofreading device and the two gross weight electronic scales are all in communication connection with the labeling machine. In addition to the feeding process, operators do not make contact with products with bare hands any more, the products are prevented from being polluted, weighing is accurate, and the automation degree is high.

Description

technical field [0001] The invention relates to automatic weighing and packaging equipment for precious metal particles and a weighing method thereof, belonging to the technical field of packaging equipment. Background technique [0002] Gold is the elemental form of the chemical element gold (chemical element symbol Au), a soft, golden-yellow, corrosion-resistant precious metal. Gold is one of the rarer, most precious and highly valued metals. In the world, gold is generally measured in ounces. In ancient China, "two" was used as the unit of gold. It is a very important metal. It is not only a special currency used for reserve and investment, but also an important material for jewelry industry, electronics industry, modern communication, aerospace industry and other sectors. With the development of modern society and the improvement of the quality of life, people's demand for some highly ornamental items with the function of adding value and maintaining value is gradually...
