The Application of Peristaltic Pump in the Delivery of Ink in Inkjet Printers

Hours

        The peristaltic pump is capable of accurately transporting various high-viscosity inks, with suction and lift capabilities exceeding 5 meters. Additionally, the peristaltic pump can easily change the direction of flow and has the function of a stop valve, eliminating the need for check valves in the pipeline. The precision of its transportation can reach up to 1%, and it is very convenient to adjust the speed. Therefore, when used as an ink pump, the peristaltic pump is an ideal choice.

        During the high-speed printing process of an inkjet printer, itDuring the high-speed printing process of an inkjet printer, it is necessary to continuously transport ink to the printhead. As a result, the ink in the cartridge will gradually decrease. To ensure a continuous supply of ink, the ink tube is usually inserted into an external ink tank, and a pump is used to transport the ink to a secondary ink cartridge for intermediate storage. Inkjet printers often use diaphragm pumps as ink transport pumps or to collect and discharge waste ink. While this type of pump is relatively inexpensive, it may cause damage to the pump or unstable flow when transporting solvent-based or highly viscous inks. Additionally, it can lead to issues such as residual ink in the pump and dead corners.

        MN1 is a constant speed micro peristaltic pump driven by a 12V or 24V DC power supply, with adjustable flow rate (by selecting different motor speeds). The MN1 peristaltic pump is equipped with a DC geared motor, ensuring high reliability and stability during ink transportation. It prevents the pump from ceasing liquid output or ink suction due to pump tube wear.

        Some peristaltic pumps without gearboxes rely on three wheels surrounding the motor shaft. The shaft rotates at high speed, driving the three wheels to perform planetary motion. The transmission is achieved solely through friction between the shaft and the wheels. If the pump tube or wheel wear occurs, the pump will stop dispensing fluid, and it may even cease operation when the outlet resistance increases.
