Description

Technical Field

[0001] The utility model relates to the technical field of two-dimensional code tracing, in particular to a two-dimensional code tracing device for food quality detection. Background Art

[0002] Food safety means that food is non-toxic, harmless, meets the necessary nutritional requirements, and does not cause any acute, subacute or chronic harm to human health;

[0003] In order to facilitate the traceability of food quality and food safety, a QR code is often printed on the surface of the food packaging bag. When the food quality inspector conducts random inspection of the food, he can trace the source by scanning the QR code on the food packaging bag through a QR code traceability device. Most of the existing QR code traceability devices are composed of a bracket and a scanning head. The food is placed on the bracket and then the scanning head is aligned with the QR code on the food packaging bag for scanning. However, in the actual scanning process, since the packaging bag is filled with food, the QR code is easily lifted up by the food, resulting in inaccurate scanning, which requires manual assistance. In addition, the presence of frozen frost or stains on the food packaging bag will also affect the accuracy of the code scanning. Therefore, we propose a QR code traceability device for food quality inspection. Utility Model Content

[0004] The purpose of the utility model is to provide a two-dimensional code traceability device for food quality detection, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a two-dimensional code traceability device for food quality inspection, comprising a base, one side wall of the base is fixedly connected to a support plate, one side wall of the support plate is connected to a cross plate, a two-dimensional code scanning head is fixed to the bottom of the cross plate, both sides of the top of the base are connected to a gantry, a first electric push rod is fixed at the middle of the top of the gantry, the push rod of the first electric push rod movably passes through the gantry and is fixedly connected to a pressure plate, first limiting grooves are opened on both sides of the top of the base, and matching first limiting sliders are inserted on both sides of the inner cavity of the first limiting groove, a third electric push rod is fixedly connected to the side wall of the first limiting slider, the outer end of the third electric push rod is fixedly connected to the inner wall of the first limiting groove, and the top of the first limiting slider is fixedly connected to the end of the gantry.

[0006] By adopting the above technical solution, the food packaging bag is placed on the top of the base, and then the third electric push rod is started to drive the gantries on both sides to move, so that one of the gantries moves to one end of the packaging bag, and then the corresponding first electric push rod drives the corresponding pressure plate to descend and press one end of the packaging bag, and then the other gantry is moved and the pressure plate applies a certain pressure to the packaging bag, so that the moving pressure plate can be used to scrape the adapter inside the packaging bag flat, thereby ensuring that the QR code is in a flat state, thereby ensuring that the QR code scanning head scans the code accurately.

[0007] As a preferred embodiment of the present invention, a sponge strip adapted to the pressing plate is detachably fixed to the bottom of the pressing plate.

[0008] By adopting the above technical solution and setting the sponge strip, the pressing plate can wipe off frost and stains when scraping the surface of the packaging bag, thereby further improving the accuracy of code scanning.

[0009] As a preferred embodiment of the utility model, a second limiting slide groove is opened on one side wall of the support plate, a matching second limiting slide groove is inserted into the inner cavity of the second limiting slide groove, a second electric push rod is fixedly connected to the top of the second limiting slide groove, an outer end of the second electric push rod is fixedly connected to the top of the inner cavity of the second limiting slide groove, and an outer wall of the second limiting slide groove is fixedly connected to the end of the cross plate.

[0010] By adopting the above technical solution, when scanning with the QR code scanning head, starting the second electric push rod can drive the second limit slider to move up and down, thereby driving the cross plate to move up and down, and then adjusting the position of the QR code scanning head, thereby further ensuring the accuracy of scanning.

[0011] As a preferred implementation of the utility model, the two-dimensional code scanning head is arranged directly opposite to the middle of the top of the base.

[0012] By adopting the above technical solution, the accuracy of the two-dimensional code scanning head when scanning codes is further improved.

[0013] As a preferred embodiment of the present invention, adaptive rubber pads are fixed at the four corners of the bottom of the base.

[0014] By adopting the above technical solution and providing the rubber pad, the device as a whole can be prevented from sliding when placed for use, thereby ensuring stability during use.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The technical solution of the present application is a two-dimensional code traceability device for food quality inspection, which uses one of the first electric push rods to drive the pressing plate to press and stabilize one end of the food packaging bag, and then uses another first electric push rod to drive the pressing plate to fit the surface of the packaging bag, and then uses the third electric push rod to drive the gantry to move, so that the pressing plate moves accordingly to scrape the packaging bag flat, thereby ensuring the flatness of the two-dimensional code, thereby ensuring the accuracy of code scanning;

[0017] When the packaging bag is flattened by moving the pressing plate, the sponge strip at the bottom of the pressing plate can be used to wipe the surface of the packaging bag, so as to wipe off the frost or stains at the QR code on the surface of the packaging bag, thereby further improving the accuracy of code scanning.
