Problems solved by technology

[0003] Some food packaging will fill the packaging bag with protective gas to ensure that the food is not easy to deteriorate. If the airtightness of the packaging bag is not good, it will cause adverse effects such as moisture, rot, and crushing of the food inside. However, the current gas The tightness test cannot be applied to the assembly line of the food factory, and only a small number of product sampling tests can be carried out

Embodiment 1

[0053] Such as Figure 1-7As shown, this embodiment provides a transmission device for testing the airtightness of food packaging, including a bracket 1, a transmission mechanism, a spring pressing mechanism and a main control mechanism, and the main control mechanism includes a processor 2 and a driving device 3 , the processor 2 is connected to the drive device 3;

[0054] The conveying mechanism includes two independent conveying belts 4, the conveying belts 4 are connected with the driving device 3, and are used to convey the articles to be inspected and the inspected articles;

[0055] The support 1 is arranged on the periphery of the transmission mechanism, and the support 1 includes a camera 5 connected to the processor 2 for acquiring images of objects to be detected on the conveyor belt 4 and The image is sent to the processor 2;

[0056] The spring pressing mechanism is arranged on the support 1, and the spring pressing mechanism includes a loading platform 6, a fl...

Embodiment 2

[0073] Such as Figure 8 As shown, a working method of a conveying device for testing the airtightness of food packaging includes the following working steps:

[0074] S101: The camera device 5 acquires an image on the conveyor belt 4 and sends the image to the processor 2;

[0075] S102: The processor 2 determines whether the item to be detected has filled the channel according to the image;

[0076] S103: If yes, the processor 2 outputs a first rotation signal to the driving device 3, and the driving device 3 drives the reversing block 12 to rotate clockwise by 90 degrees;

[0077] S104: the processor 2 outputs an extension signal to the driving device 3, and the driving device 3 drives the telescopic device 8 to extend a preset length;

[0078] S105: the processor 2 outputs a pop-up signal to the driving device 3, and the driving device 3 drives the pop-up device 10 to start;

[0079] S106: The resistance sensor 11 detects the force value of the soft ball 13 and sends th...

Embodiment 3

[0108] Such as Figure 10 As shown, before the item to be detected enters the channel, it also includes:

[0109] The processor 2 outputs a third rotation signal to the driving device 3, and the driving device 3 drives the rotating device 14 to rotate downward by 90 degrees.

[0110] The processor 2 judges whether the items to be detected are evenly distributed in front of the channel according to the received images;

[0111] If not, the processor 2 outputs a sorting signal to the driving device 3, and the driving device 3 drives a sorting arm to evenly arrange the items to be detected in front of each entrance of the channel.

[0112] Specifically, during the process of putting the items to be detected on the conveyor belt 4, the accumulation of items may occur. When the accumulated items enter the distribution device 7 together, the telescopic device 8 will not be able to extend the preset length.

[0113] In order to avoid the above situation, a rotating device 14 and an...

Description

technical field [0001] The invention relates to the field of food testing, in particular to a conveying device for testing the airtightness of food packaging and a working method thereof. Background technique [0002] Food safety is related to the health of consumers. Food safety is not only related to the material of the food itself, but also to the packaging of the food. Therefore, the airtightness index of food packaging is an important testing item for packaged food. [0003] Some food packaging will fill the packaging bag with protective gas to ensure that the food is not easy to deteriorate. If the airtightness of the packaging bag is not good, it will cause adverse effects such as moisture, rot, and crushing of the food inside. However, the current gas Tightness inspection cannot be applied to the assembly line of food products, and only a small amount of product sampling inspection can be carried out. Contents of the invention [0004] Purpose of the invention: In...
