Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to a coding device for food packaging bags. Background Art

[0002] Food packaging bag coding systems are automated devices that print information such as the production date, batch number, and expiration date on food packaging. These systems typically consist of a printing system, a control system, a transmission mechanism, and an ink supply system. The printing system sprays ink in the form of tiny droplets onto the packaging material, creating legible text or images. The control system controls the content, location, and speed of the printing according to pre-set programming. The transmission mechanism ensures that the printhead accurately prints along the packaging material's path. The ink supply system provides a continuous supply of ink to the printhead.

[0003] Since food packaging bags are light and soft, wrinkles may appear on the surface of the food packaging bags when the barcode is sprayed on them. After the inkjet printer sprays the barcode on the food packaging bags, the food packaging bags are opened and the barcode may be garbled, resulting in unclear barcodes. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The utility model provides support for the swing frame through the cooperation between the pressure plate, the swing frame and the spring, and maintains the stability of the swing frame during rotation. When the sliding column moves downward, the swing frame drives the pressure plate to contact the food packaging bag. After the pressure plate contacts the food packaging bag, it receives resistance, and the pressure plate drives the swing frame to swing outward, smoothing the position of the wrinkles in the food packaging bag while swinging. The outward swinging of the pressure plate simulates a human hand to push the food packaging bag outward to open it. After the food packaging bag is opened outward, the position of the wrinkles is smoothed by the pressure plate, thereby improving the clarity of the barcode spraying.

[0013] 2. The cooperation between the spring 1, the nut 2 and the pull rod of the utility model is achieved by rotating the nut 2 to move the position. After the nut 2 moves the position, the compression spacing of the spring 1 is adjusted. After the spacing is changed, the spring 1 changes the elastic support strength of the guide rail. The guide rail is elastically supported by the spring pair. If the contact force between the pressure plate and the food packaging bag is too large, the springs work together to provide a buffering effect, thereby improving the safety of the food packaging bag.

When the pressure plate 14 swings outward, it drives the swing frame 13 to swing outward at the same time. When the swing frame 13 swings, it compresses the spring 2 17 through the support block 19. After the inkjet printer body 3 completes the inkjet printing operation, the electric push rod 8 drives the slide column 7 to move upward. Subsequently, the spring 2 17 pushes the swing frame 13 and the pressure plate 14 to reset.
