In the press and dryer part, the doctor blade continuously removes fine fibers, sizing agents, and chemical deposits adhering to the surfaces of the press rolls and dryer. In case of paper breakage or feeding, the doctor blade effectively peels the paper sheet from the roll surface, guiding it into the waste paper pit, preventing paper web entanglement on the rolls and causing equipment damage and downtime. On the coating machine, the coating doctor blade precisely controls the amount of coating applied to the paper surface, eliminating defects such as streaks and drips, directly affecting the printability of the coated paper. On a toilet paper machine, the creping doctor blade works in conjunction with the Yankee dryer cylinder to create fine wrinkles in the paper sheet through precise scraping, giving toilet paper its softness and bulk.

The selection of doctor blade material requires comprehensive consideration of roll surface material, operating temperature, wear resistance requirements, and operating speed. A high-quality doctor blade depends not only on the material but also on precise manufacturing processes. When selecting doctor blade, the following technical specifications should be given priority: balance between hardness and toughness; blade shape design; dimensional accuracy; and oscillation mechanism.

We are committed to providing customized doctor blade solutions for various paper machines (cultural paper machines, packaging paper machines, tissue paper machines, and specialty paper machines). Whether you need highly wear-resistant ceramic coating blades, EP composite blades to protect the roll surface, or precision creping blades, we can meet your needs.
