[0002] The weight detector is an automated device mainly used for online dynamic weighing of products passing through the automated packaging line. It can detect products with unqualified weight during continuous working and can automatically classify products. The weight detector is a device for detecting product weight in industrial production.

[0004] However, the weight detection machine in patent authorization number CN216174362U only has the function of detecting the weight of the product. Usually, the appearance of the product needs to be inspected after weighing. Therefore, another device for product appearance inspection is required, which not only takes up space on the production line, but also increases the time of product transportation when transferring from the weighing production line to the appearance inspection production line, thereby affecting the overall efficiency of product production. Therefore, we propose a weight detection machine that integrates appearance inspection to solve the above problems. Utility Model Content
