Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to a weighing and counting system. Background Art

[0002] With the development of the times, when various products are packaged, there are unified regulations on the specifications, sizes, parameters, ingredients, and weight of the products; therefore, in the process of product packaging, the weight of the products needs to be strictly inspected. For products whose weight does not meet the requirements, they need to be sorted and reprocessed to ensure the eligibility of the products on the production line; and for products whose weight meets the requirements, their quantity needs to be counted; thus, a machine that can weigh, sort and count the products is needed on the production line.

[0003] At present, in the prior art, there are already weight sorting machines on the market, but these sorting machines are relatively complex in structure, inconvenient to operate, and prone to errors when sorting products, resulting in inconsistent processing, low work efficiency, or the accuracy of weighing results being affected by personnel or other factors.

[0004] Also, during the production process, for products whose weight meets the requirements, the verification and counting of their quantity are often done manually. This method can easily lead to inaccurate measurement of product quantity verification, resulting in technical problems such as wasting manpower and material resources and greatly reducing the economic benefits of the production line.
