Description

Technical Field

[0001] This utility model relates to the technical field of printing information on tobacco filter stick packaging boxes, and in particular to a thermal foam printer for tobacco filter stick packaging boxes. Background Technology

[0002] In modern tobacco industry production, ensuring the accuracy and traceability of product information is crucial. Printing relevant information and QR codes on filter stick packaging boxes, in particular, not only improves market transparency but also enhances consumer trust in the brand. Traditional manual marking methods are inefficient, error-prone, and unsuitable for large-scale production lines. Therefore, adopting automated label printing equipment has become an inevitable trend in the industry. Thermal inkjet printers (TIJs), with their high efficiency, flexibility, and high-quality printing results, are gradually becoming the preferred tool for label printing on tobacco filter stick packaging boxes. They can quickly print text, barcodes, QR codes, and graphics directly onto packaging materials, greatly improving production efficiency and information accuracy.

[0003] To meet the specific requirements of tobacco filter stick packaging, the printers used on the production line need to possess high adaptability and stability. Firstly, since tobacco filter stick packaging boxes typically contain various information, such as production date, batch number, expiration date, brand logo, and anti-counterfeiting QR codes, the printer must support simultaneous printing of multiple data types while ensuring the clarity and accuracy of every detail. Secondly, considering the speed of the production line, the printer must be able to seamlessly integrate with the line, achieving high-speed printing without affecting product quality. Finally, to handle packaging boxes of different sizes and shapes, the printer also needs a degree of flexibility to adjust the printing position and format. Using advanced printhead combinations, such as side-by-side, overlapping, or matrix combinations, can meet all of these requirements and provide strong support for subsequent quality control.

[0004] However, in practical applications, existing technologies still face several challenges in quickly, accurately, and clearly printing label information on tobacco filter stick packaging boxes. For example, how to ensure perfect integration of the printing system with existing production lines to avoid missed or duplicate printing due to speed mismatch; how to further increase printing speed while maintaining print quality to meet growing production demands; and how to simplify operating procedures so that non-professionals can easily perform routine maintenance and troubleshooting. Based on these considerations, developing a packaging box label printer specifically designed for tobacco filter stick packaging box production lines is particularly important. This printer not only needs high-precision printing capabilities but also good compatibility and ease of use, thereby comprehensively improving the automation and management levels of tobacco production.

A photoelectric sensor is installed in front of the printhead unit to detect whether the tobacco filter stick packaging box has reached the printer area. The printhead unit includes a distance sensor to detect the distance between the printhead unit and the tobacco filter stick packaging box. Using a photoelectric sensor to detect whether the tobacco filter stick packaging box has reached the printer area ensures that the printing action is triggered only at the appropriate time, avoiding missed prints or duplicate prints, and improving printing efficiency and accuracy. Simultaneously, the distance sensor in front of the printhead unit 6 monitors the distance between the printhead and the packaging box in real time, ensuring optimal print quality during the printing process, maintaining clarity even on a high-speed production line.

[0024] like Figure 3 As shown, the printhead unit 6 includes a thermal inkjet printer printhead 10 and a U-shaped slot frame 601. Multiple U-shaped slot frames 601 are fixed side by side, and the U-shaped slot frames 601 are raised sequentially to form a staircase shape. The thermal inkjet printer printhead 10 is installed inside the U-shaped slot frame 601. An assembly plate 602 is also provided on the side of the U-shaped slot frame 601 facing the production line. The assembly plate 602 is provided with perforations corresponding to the printhead. The thermal inkjet printer printhead 10 sprays information onto the tobacco filter rod packaging box through the perforations.

[0025] The stair-like arrangement of the U-shaped slots 601 allows the printheads to be mounted at different heights, enabling multi-line printing and the separate printing of different information, such as production date, batch number, expiration date, brand logo, and anti-counterfeiting QR code. The side-by-side arrangement of the U-shaped slots 601s also allows for increasing or decreasing the number of printheads as needed, further enhancing the printer's usability. In this embodiment, three sets of printheads are used as an example, with three U-shaped slots 601s fixed side-by-side.

[0026] The printer provided by this utility model also includes a control box, such as Figure 4 As shown, the control box receives signals from the photoelectric sensor and the distance sensor, and controls the electric cylinder 5 and the print head to complete the printing of information on the packaging box according to the relevant signals.

[0027] The control box is also equipped with a 5G module, a Wi-Fi module, a network interface, and a USB interface. The text of the tag information can be input into the control box via the network and a USB flash drive, and then printed by the print head.

[0028] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
