The main thing that will use the ring knife in the pad printing machine is the oil cup pad printing machine. The oil cup pad printing machine needs to use a ceramic ring knife to scrape the ink during the printing process to ensure the uniform distribution of the ink and the printing quality. Ceramic ring knives are usually made of zirconia ceramic, which has the characteristics of high wear resistance and high strength, and can adapt to the long-term use needs of pad printing machines 12.

The role of ring knife in pad printing machine

The role of ring knife in pad printing machine mainly includes the following aspects:

Scraping Ink: The ring knife is used to scrape the ink in the oil cup to ensure that the ink is evenly distributed on the printing plate, so as to achieve high-quality printing results.

Evenly distributed ink: Through the scraping action of the ring knife, the ink can be evenly distributed on the printing plate, avoiding too much or too little ink, and ensuring the clarity and consistency of the printed matter.

Adapt to high-intensity use: Ceramic ring knife has the characteristics of high wear resistance and high strength, which can maintain stable performance in long-term use, reduce replacement frequency and reduce maintenance costs.

The material and type of ring knife

Ring knives are usually made of ceramic materials, common materials include zirconia ceramic. This material has high hardness, high wear resistance and corrosion resistance, and can adapt to the high-intensity use needs of pad printing machines. Different types of ring knives may vary in size and shape, but the basic function is to better scrape and distribute the ink13.

Maintenance and replacement of ring knives

During use, ring knives need to be checked and maintained regularly to ensure that they are working properly. If the ring knife is found to be severely worn or malfunctioning, it needs to be replaced in time. When replacing, attention should be paid to choosing a ring knife that matches the model of the pad printing machine to ensure the best printing effect and service life
