Durable Compound Doctor Blade Holder for Industrial Printing Machine

          Pneumatic Doctor Blade is a key device in paper machinery for cleaning the surfaces of drying cylinders, press rollers and other equipment. It precisely controls the scraper pressure (linear pressure range 0.3-1.5 MPa) through a Pneumatic system to efficiently remove residual paper scraps, rubber compound and impurities, ensuring the quality of paper surface and the stability of equipment operation. Its main body is made of 304 stainless steel or tungsten carbide coated blades (with a thickness of 1-6mm), suitable for roller diameters of Φ800-6000 mm, and the working temperature can reach 180°C. The products include standard type, Air-Cushioned type (flexible contact to prevent roller surface damage) and Oscillating type (Oscillating for uniform cleaning). They support PLC intelligent control (pressure ±2% error) and modular quick-change design. With an IP65 protection level, they are suitable for high-speed paper machines (≤2000 m/min). It saves energy by 15%-20%, complies with the ISO 15361 standard, and is widely used in the production lines of cultural paper, toilet paper and packaging paper.
