Product Description

Paper Machine High Speed Stainless Steel 316 Doctor Blade for Paper MakingBlade holders position the doctor or roll cleaning blade firmly against the roll, accommodate roll surface irregularities, facilitate rapid blade changes, and, within limits, compensate for thermal expansion.

Proper doctoring or roll cleaning is critical to many industrial processes and goes beyond choosing a doctor or roll cleaning blade.

We build our blade holders for consistent performance in the most demanding environments. LEIZHAN blade holders are manufactured to our precise standards and lead the industry in durability. 
 

K-35 Blade Holder

1. The pressurization method depends on its own weight. Generally, the knife is manually lifted and closed. However, in some important occasions, the line pressure, the doctor blade can be lifted and the pressurization can be adjusted remotely by the air cylinder. Such as the tension roller doctor blade in the wire section of the paper machine, and the dryer doctor blade in the drying section.
2. Through the fine adjustment bolt, the pressure of the blade can be adjusted.

Single air bag blade

Since only one hose is used to realize the two functions of loading and unloading, the hose is assembled in the factory and fixed in cold position to ensure very fast and trouble-free replacement. Only one hose means that only one connecting air pipe is needed, reducing the cost of installation. The blade holder has a flat surface and can be installed with a paper blowing pipe.

Double air bag single blade

Paper Machine High Speed Stainless Steel 316 Doctor Blade for Paper Making
The doctor blade system is composed of a pneumatic thumb, a blade body, and a swinging device. The core component is the pneumatic thumb, which is connected to the blade body through a rotating shaft. The doctor blade is inserted in the middle of the pneumatic thumb knife magazine. The pressure of the blade is pressurized by the pneumatic thumb. The two pneumatic tires and pressure relief are completed. The blade body is used to fix the pneumatic thumb. It must have sufficient rigidity and straightness.
The double air-bag blades can able to keep the roller surface clean while maintaining a proper lineal pressure and angle and protecting materials. Besides, it can reduce ends down and paper defects, effectively protect roller surface, prolong the service life of roller, and reduce the frequency of shutdown for replacement and maintenance, thus improving the economic benefit. 

Advantage:
1.The air-bag can make the blade contact with any point of the roller very well and prevent scratching the roller.
2. Adjust the pressure of the air supply through the pressure reducing valve, so that the line pressure can be effectively controlled.
3.The thickness of the blade can be freely selected from 1mm up to 6mm, and the blade can be easily replaced.

Double air bag double blade

Paper Machine High Speed Stainless Steel 316 Doctor Blade for Paper Making
The double-blade system, made up by two air-bag blades, it means using two air-bag blades at the same time. It is used to remove the moisture and dirt attached to the roller surface. During the operation, plenty of pores will form on the roller surface as well as on the abrasive side of edge. Therefore, small dirt and moisture will enter into the back surface of blade through these pores. Some dirt will be taken away be paper, while some will attach to the back of blade, forming lumps which will drop after a long time, thus causing paper breakage and even machine halt. Such condition is even more serious for the stone roller in the press section. In addition, a great lineal pressure exerted by the blade may produce negative pressure at the back of blade which causes plenty of dirt to gather on the front of blade, thus seriously affecting product quality.
Application of double air bag double doctor blade:
The double-blade system is equipped in the central press section, couch roll in the net section and so on. Under the action of centrifugal force, the moisture and fine fibers will be thrown away from the pores of couch roll and vacuum compression roller, and then attach to the first blade which is able to destroy their surface tension, remove part of moisture and fine fibers and form a small negative pressure behind the blade. The second blade will clear away the moisture and fine fibers expelled from the pores by the small negative pressure.
