An inkjet printer is a computer peripheral that produces hard copies of a text document or photo by spraying droplets of ink onto paper.
In the inkjet printing mechanism, the print head has several tiny nozzles, also called jets. As the paper moves past the print head, the nozzles spray the ink onto it, forming the characters and images.
The Problems of Inkjet Printer transferring the ink
During high-speed printing, the inkjet printer needs to continuously deliver ink to the nozzle, and the ink will continue to decrease. In order to ensure a continuous supply of ink, the ink tube is usually inserted into an external ink barrel and a pump is used to deliver the ink to the auxiliary ink cartridge for transfer.
Inkjet printers often adopt diaphragm pumps as ink delivery pumps, or collect and discharge waste ink. Although diaphragm pumps are cheap, when transferring solvent-based inks or inks with high viscosity, the pump will be damaged or the flow rate will be unstable during the delivery process. And it will also cause problems such as dead corners of ink residue in the pump.
Peristaltic Pump Applied in Inkjet Printer
Precision peristaltic pump also called peristaltic tube pump is an innovative pumps solving the micro liquid transferring, filling and dispensing. The peristaltic pump works by squeezing and releasing the tube through a roller to push the liquid froward. It features dry running, self-priming and no contamination.
Peristaltic pumps are widely used in the pharmaceutical, food, chemical and other industries to transport media that are sensitive, viscous, highly corrosive, abrasive, and have high purity requirements.
Ink delivery
- Precise ink supply: The peristaltic pump accurately control the ink delivery volume, ensuring that the nozzle obtains a stable and continuous ink supply during high-speed printing. Thereby it ensure the printing quality, making the pattern colorful and clear, and avoiding ink interruption and ink leakage. Its transmission accuracy can usually reach about 1%, which is crucial for some inkjet printing jobs that require high color accuracy.
- Transferring various inks: It can deliver various types of inks, including water-based inks, solvent-based inks, UV-curable inks, etc., as well as inks of different viscosities and chemical properties. For inks with higher viscosity, peristaltic pumps can better overcome resistance and deliver them, without being easily damaged or experiencing unstable flow like some traditional diaphragm pumps; they can also deliver inks containing granular pigments smoothly. , will not cause nozzle clogging.
- Best suction and lift: The suction and lift capabilities are strong, generally more than 5 meters, which makes the printer more flexible when connecting to external ink barrels. You can choose the appropriate ink barrel position according to actual needs without worrying about ink The problem of not being able to be delivered to the nozzle smoothly.
Waste ink collection and treatment
- Stable collection: During the printing process, a certain amount of waste ink will be generated, and the peristaltic pump can be used to collect and discharge the waste ink. It can provide a stable negative pressure to ensure that waste ink can be collected into the waste ink storage device in a timely and effective manner, preventing waste ink from accumulating around the printhead and adversely affecting the printhead and printing quality.
Prevent backflow: The peristaltic pump has good sealing and one-way delivery function. When collecting waste ink, it can effectively prevent the waste ink from flowing back into the nozzle or ink supply system, ensuring the normal operation of the inkjet printer.
