Overview

　　The Guanshentai Automatic Pipette Screen Printing Machine is specialized equipment designed for precision screen printing on the outer surfaces of long, tubular containers such as pipettes, Pasteur pipettes, and droppers. Integrating automatic tube loading, surface flame/corona treatment, precision multi-segment curved-surface screen printing, UV curing/hot-air drying, and automatic unloading, the system automates the entire process—from handling bulk tubes to producing finished, printed units. It is capable of printing various graphic elements, including graduation marks, identification symbols, brand logos, and usage instructions.

　　Key Advantages:

　　Multi-segment Printing for Long Tubes: Utilizing servo-driven axial movement and synchronized rotation—combined with a precision guidance mechanism—the machine supports multi-segment, zoned printing in a single pass. It is particularly well-suited for the continuous, precise printing of full-length graduation marks and markings on pipettes, achieving a printing accuracy of ±0.1mm with crisp, undistorted graphics.

　　Uniform Ink Layer with Strong Adhesion: Equipped with a pre-printing flame or corona treatment station, the machine effectively enhances surface tension and ink adhesion. When used with specialized UV or solvent-based inks, the resulting print is resistant to abrasion and alcohol wiping, meeting the durability requirements for reusable laboratory consumables.

　　Specialized Tube Conveying System: Designed to handle the high aspect ratio and flexibility of pipettes, the system employs specialized flexible guide rails and multi-point positioning supports. This ensures stable transport and precise positioning, preventing the long tubes from wobbling, shifting, or bending during the printing process.

　　Scratch-resistant Design: All contact points utilize non-metallic, flexible materials (such as Teflon, polyurethane, or silicone). The clamping and positioning mechanisms feature adjustable pressure to prevent wall scratches or tip deformation, ensuring high product visual quality.

　　Instant Curing: Equipped with high-efficiency UV-LED curing lamps or an infrared hot-air drying system, the ink dries immediately upon printing. The cured finish is non-tacky and durable, allowing products to proceed directly to packaging without a waiting period, thereby effectively shortening the production cycle.

　　Material Shortage Detection & Protection: Equipped with systems for detecting missing tubes in the hopper, photoelectric positioning for print registration, and automatic squeegee pressure monitoring. The machine skips printing if a tube is missing and automatically stops with an alarm in the event of a tube jam, ensuring continuous, stable operation.

　　Broad Material Compatibility: Compatible with various materials such as PP, PE, PS, PETG, and glass. It accommodates tube lengths of 80–300 mm and diameters of 3–20 mm; switching between product specifications is quick and easy, requiring only a change of track molds and adjustment of the positioning mechanism.

　　User-Friendly Operation: Features a PLC and touchscreen HMI. Parameters such as printing speed, squeegee stroke, screen lift, and curing power can be set with a single touch, and multiple recipe profiles can be saved. Product changeovers are rapid, and general operators can run the machine after minimal training.

　　Applications:

　　Widely used for printing markings on various long, tubular containers, including life science consumables (pipettes, Pasteur pipettes, serological pipettes, disposable droppers), medical consumables (urine droppers, medication droppers), and laboratory equipment. With its precise, efficient, and stable printing performance, the Guanshentai automatic pipette screen printing machine helps laboratory consumable manufacturers automate their long-tube marking processes, thereby enhancing brand recognition and market competitiveness.
