Principle of curved screen printer
The unfolded surface of a cylinder is a cuboid, and a cuboid rolled up is a cylinder. In mechanical principles, the meshing of gears and racks can be used to simulate the relative motion of cylinders and cuboids respectively. The trajectory of the generatrix of the rack and the generatrix of the gear overlap when meshing transmission occurs. If the screen is fixed on the rack and the cylindrical product is fixed on the gear, the screen will form a rectangular unfolded surface on the surface of the cylinder. This is the principle of the curved screen printer.
Structure of curved screen printer
• Printing head: including scraper and screen. The scraper pushes the ink through the screen for printing. The screen printer with up and down movement of the workbench, the printing head remains stationary. Some curved screen printers require the printing head to move up and down while the workbench remains stationary.
• Substrate fixture: used to fix various bottles such as red wine bottles and beer bottles to ensure the stable position of the bottles during printing. It can usually be adjusted according to the size and shape of the bottles. The substrate fixture can be blown and is used for relatively soft bottles. If the bottle only needs to be printed in one color, friction transmission can reduce costs. If color matching is required, the fixture must be equipped with transmission gears.
• Transmission system: enables the substrate fixture to rotate or move, so that the bottle surface is fully in contact with the screen plate to achieve curved surface printing. Semi-automatic screen printing machines mainly use gear rack transmission.
Features of curved screen printing machines
• Wide applicability: can print bottles of various shapes such as red wine bottles and beer bottles, whether cylindrical or special curved bottles.
• Easy operation: workers only need to place the bottle on the fixture and start the machine to complete the printing process, without complex operating skills.
• Good printing effect: can clearly print high-quality patterns and text on curved objects, the pattern has strong adhesion and is not easy to fade.
• High production efficiency: Continuous printing can be achieved, which is especially beneficial for mass production of hot-selling products and can meet market demand.

Function |
|
| Summary: | For the printing of cylinders, elliptical cylinders, cones, especially hollow plastic containers, the most preferred choice is the curved surface screen printing machine. The curved surface screen printing machine transfers the left and right movement of the flat screen to the curved surface product through gear transmission or friction transmission. For the printing machinery on the linear contact surface, the continuous rotation of the product, and the part in contact with the surface will continuously receive the ink transfer on the screen to achieve printing. The significant difference between the curved surface screen printing machine and the flat screen printing machine is that its fixture actually completes the rotation of the product, and the rotation process is in linear contact with the movement of the screen, and no slippage can occur. Therefore, the main elements of the curved screen printing machine are: screen printing screen, screen printing ink, screen printing squeegee, and the squeegee on the curved screen printing machine is usually a squeegee with a triangular cross-section. The screen printing jig has various forms, and its main feature is to ensure the precise and stable rotation of the product. The curved screen printing machine can print tiny cylinders such as straws and pen refills with a diameter of 1mm, and can also print plastic barrels, oil barrels, and water heater shells with a diameter of more than 500mm. Screens and fixtures will do. |
