AI Technical Summary

Technical Problem

During the production and processing of existing canned food cans, some can openings become deformed and irregular, resulting in defective products that cannot meet the requirements for subsequent packaging. Currently, the screening mainly relies on manual inspection, which leads to low work efficiency.

Method used

Design an automatic rejection device, including a conveyor, a camera, a cylinder, a pusher plate, and a limiting component. The camera detects defective products and the cylinder drives the pusher plate to push them out. The limiting component ensures that the product is centered, thus achieving automated screening.

Benefits of technology

It has enabled automated screening of defective canned goods, improved work efficiency, reduced manual intervention, and enhanced the level of automation in the production process.

Abstract

The utility model relates to the technical field of food processing, in particular to an automatic waste rejecting device for nutritious food processing, which comprises a mounting frame and a rejecting component, and the rejecting component comprises a controller, a support, a conveyor, a limiting component, a camera, an air cylinder and a push plate. Products needing to be detected are placed on the conveyor to be conveyed through equal difference arrangement, photographing detection is conducted through the camera in the conveying process, when unqualified products are detected through photographing, the push plate is driven by the air cylinder to push the defective products out of the device, and the push plate is convenient to push due to the arc-shaped design; the limiting component is used for limiting the positions of the two sides of the product in the conveying process, it is guaranteed that the product is kept in the middle, shooting of a camera is facilitated, and the problems that in the production and machining process of existing cans, defective products with part of can openings deformed irregularly appear and do not conform to follow-up packaging, and the working efficiency is low due to the fact that manual detection is usually adopted in existing screening are solved.
