Description

A packaging inspection device for a food processing line

technical field

The utility model relates to the field of packaging detection devices, in particular to a packaging detection device for food processing lines.

Background technique

In food processing and packaging line operations, whether food packaging is qualified directly affects the effective shelf life of food. In the process of packaging inspection, it is generally necessary to reject products with substandard packaging and empty packaging. The detection method in the prior art is to detect the problems of unqualified packaging and empty packaging one by one, and when unqualified packaging or empty packaging is detected, an alarm is issued one by one, and then the post personnel go to the corresponding position to carry out manual removal. The detection method in the prior art has following shortcoming:

1. The detection device in the prior art is complex in structure, difficult to operate, and high in detection cost.

2. The detection of unqualified packaging and the detection of empty packaging are divided into two steps, which leads to the extension of food processing and packaging lines. Unnecessary economic expenditures are caused, which affect the company's efficiency.

3. For bagged food and boxed food, the existing detection device is only suitable for the detection of one type of food, and has a single function.

4. For food packaged with nitrogen gas, when the effective seal width of the food bag seal is narrow, although the food bag has been sealed, the seal of the food bag is easy to crack due to the narrow effective seal width during transportation or handling. If it is opened, the food inside the food bag will be in contact with the outside world, which will seriously affect the shelf life of the food.
