Description

Technical Field

[0001] This utility model relates to the field of fruit juice production technology, and in particular to an automatic inkjet printing and packaging production line for fruit juice beverages. Background Technology

[0002] With the development of large-scale and standardized production in the beverage industry, the demand for product traceability, production information labeling, and anti-counterfeiting is becoming increasingly prominent. As fast-moving consumer goods, fruit juice beverages must have their packaging clearly labeled with information such as production date, batch number, shelf life, barcode, and QR code to meet regulatory compliance and supply chain management requirements.

[0003] However, traditional inkjet printing systems suffer from inconvenient adjustment of the inkjet head and environmental sensitivity in practical applications, which directly affects production efficiency and inkjet printing quality. Early inkjet heads were mostly fastened to the bracket with bolts, and adjusting the printing height or angle required manually tightening and loosening the screws, which was inconvenient. In addition, the visual inspection system may misjudge the inkjet printing quality due to light reflection, resulting in missed printing, which required manual spot checks and re-scraping. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and propose an automatic inkjet printing packaging production line for fruit juice beverages. This line can improve the quality of inkjet printing and allow products with unqualified inkjet printing to be rejected and reworked.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The slider 25 moves along the slide 24 and the angle of the rotating plate 22 is adjusted by the push rod 28 to adapt to different discharge direction requirements. The fastener 27 locks the position of the connecting plate 26 to ensure guiding stability.

[0030] Working principle: The conveyor belt 2 moves the fruit juice beverage to the right, where it is coded by the spray nozzle 10. It then exits from the right side of the protective cover 18 and continues to move to the right. A high-definition camera 14 captures an image of the coded fruit juice beverage to check for any missed coded entries. If any missed entries are found, the electric push rod 12 pushes the push plate 13 forward, pushing the missed juice out of the opening 11. The screw 17 rotates, causing the adjusting plate 15 to move towards the center, adjusting the distance between the two adjusting plates 15 to accommodate different sizes of fruit juice beverages. The connecting plate 26 can slide left and right through the slider 25 and the chute 24. The connecting plate 26 drives the push rod 28, which in turn rotates the rotating plate 22, adjusting the distance between the ends of the two rotating plates 22 to limit the direction of fruit juice beverage transport. The electric lifting slide rail 3 drives the lifting block 4 to move vertically according to the preset bottle height. The first clamping plate 5 moves back and forth in front of the lifting block 4 via the U-shaped plate 6, adjusting the distance between the spray nozzle 10 and the fruit juice beverage.
