Problems solved by technology

Although this utility model can detect the airtightness of plastic packaging in different packaging methods at the same time, it can only detect the airtightness of one food packaging bag at a time. It is a sampling inspection with randomness and low detection efficiency. Not suitable for continuous air tightness testing of food packaging bags
In addition, in the process of testing food packaging bags, it is necessary to use various booster devices such as air pumps, and the entire testing equipment system is relatively complicated.
[0004] Another example is that the invention with application number CN201711302762.7 discloses a packaged food leak detection device, which includes a detection box and a water tank. The upper ends of the left and right sides of the detection box are provided with brackets, and the upper side of the bra

Abstract

The invention relates to a food package sealing performance detection method. The food package sealing performance detection method is characterized by comprising the following steps that a, a food package sealing performance detection system is designed, and comprises a food package bag feeding device, a sealing performance detection mechanism and a sorting mechanism; b, during detection, a detector put food packages onto a food package bag feeding device through manual work or tool assistance; c, food packaging bags are put into a portal frame plate and located between a transmission roller and a grating plate, then a telescopic device is controlled to stretch to feed the packaging bags into a detection water tank, the situation of bubbles in the water tank is shot through a camera, and a shot video is transmitted to a central processing unit; d, if the sealing problem occurs, a processor PLC of the central processing unit controls an air cylinder to stretch out to convey the unqualified food packaging bags into an unqualified product conveying rack, and the unqualified food packaging bags are conveyed out by a third conveying belt, if the sealing problem does not occur, the air cylinder of the air cylinder does not act, and the packaging bags are sent out by a second conveying belt.

Description

technical field [0001] The invention relates to the technical field of food detection, and specifically discloses a method for detecting the airtightness of food packaging. Background technique [0002] With the continuous development of the food industry, more and more food tends to develop in the retail direction, so the retail of food involves the use of more and more packaging bags, but the sealing of the packaging bags affects the packaging to a large extent The safety and quality of internal food, especially for puffed food such as potato chips, the packaging airtightness will affect the taste of the food and affect the reputation of the company. The commonly used packaging airtightness testing equipment on the market is usually a random inspection. . [0003] The utility model with the application number CN201921447909.6 discloses a device for detecting food packaging, including an operation box and a sealed bucket. The operation box is equipped with an air pump and ...
