The Guanshentai Automatic Screen Printing Machine for Centrifuge Tubes is specialized equipment designed for precision screen printing on the outer surfaces of cylindrical tubular containers, such as centrifuge tubes, test tubes, and cryovials. Integrating automatic tube loading, surface flame/corona treatment, precision 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 products. It achieves printing speeds of 30–60 tubes per minute and can print various graphic elements, including graduation marks, symbols, brand logos, and usage instructions.
Key Advantages:
Precision Curved-Surface Printing: Uses servo-driven, synchronized control of tube rotation and squeegee movement to ensure graphics remain undistorted and free from stretching on the curved surface. Printing precision reaches ±0.1 mm, delivering crisp, complete graphics suitable for fine text and dense graduation marks.
Uniform Ink Layer with Strong Adhesion: Features a pre-printing flame or corona treatment station to effectively enhance surface tension and ink adhesion. When used with specialized UV or solvent-based inks, the printed layer is resistant to abrasion and alcohol wiping, meeting the durability standards required for laboratory consumables.
Optional Multi-Color Registration: Can be configured for single-color or two-color printing based on process requirements. A precision positioning system ensures high-accuracy registration for multi-color patterns, accommodating complex logos and markings.
Scratch-Free Transport: Utilizes non-metallic, flexible guide rails throughout the transport process, combined with a pneumatic flexible clamping and positioning mechanism. This prevents tube wall scratches and rim deformation during printing, ensuring superior product appearance.
Intelligent Curing System: Equipped with high-efficiency UV-LED curing lamps or an infrared hot-air drying system. Ink dries immediately upon printing without tackiness or peeling, allowing products to proceed directly to packaging without the need for a resting period.
Material-Shortage Detection and Protection: Includes systems for detecting tube shortages in the hopper, photoelectric positioning for print alignment, and automatic monitoring of squeegee pressure. The machine halts printing if no tube is present and triggers an alarm in the event of a jam, ensuring continuous, stable operation.
Broad Material Compatibility: Compatible with centrifuge tubes and test tubes made from various materials—such as PP, PE, PS, PETG, and glass—accommodating diameters of 10–30 mm and lengths of 50–150 mm; rapid changeovers are achieved by simply swapping track molds.
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 recipes can be saved. Changeovers are quick and easy, allowing general operators to run the machine after minimal training.
Applications:
Widely applicable to surface marking and printing on various cylindrical tubular containers, including life science consumables (centrifuge tubes, micro-centrifuge tubes, PCR tubes, cryovials), medical consumables (vacuum blood collection tubes, urine tubes, sputum cups), personal care packaging (cosmetic tubes, perfume vials), and laboratory equipment. With its precise, efficient, and stable printing performance, the Guanshentai automatic centrifuge tube screen printing machine helps manufacturers of laboratory consumables automate their tube marking processes, thereby enhancing brand recognition and market competitiveness.
