Product Description

Product Description

The pneumatic tire pressurized scraper body is made of all stainless steel. The scraper device is composed of a pneumatic thumb, a scraper body, and a swing device. The core component is the pneumatic thumb, which is connected to the scraper body through a rotating shaft, and the scraper blade is inserted in the middle of the pneumatic thumb knife magazine. The pressurization of the scraper is completed by the pressurization and decompression of the pneumatic thumb with two pneumatic tires. The scraper body is used to fix the pneumatic thumb, and it must have sufficient rigidity and straightness. In order to better protect the roller surface, the scraper needs to swing back and forth at a constant speed. Depending on the use environment, the swing device has two options: pneumatic and electric. In order to facilitate the roll change, the scraper body can be installed on the scraper body to be rotated by a cylinder to obtain more space.

K-35 Stainless steel holder

Single air bag blade

In order to meet the special needs of customers, the carbon fiber composite scraper clip is developed. The scraper clip has the characteristics of durable, light weight and corrosion resistance, which can eliminate vibration, keep the roller surface and cylinder surface clean, and is easy to install and maintain.

Its simple structure, easy operation and superior performance will improve the scraper cleaning to a new height. Aste-sbcfsf is an optimized combination of 100% composite tool holder and top plate, which has excellent banner flexibility and can help the blade fully fit the roller surface.
Simple, fast and safer maintenance Aste-sbcfsf tool holder can be easily pulled out from the operation side of the paper machine for inspection and maintenance on the floor of the workshop. In this way, the cleaning of knife clip and hose will have larger space, and the maintenance work will be safer and easier.
The simple structure of aste-sbcfsf is the goal of design, which also means that there are fewer failure components. Since only one hose is used to realize loading and unloading functions, aste-sbcfsf hose is factory assembled and cold fixed to ensure very fast and trouble free replacement. Only one hose means only one connecting pipe is needed, which reduces the installation cost. The surface of the tool holder is flat and can be installed with a paper blowing tube.

Double air bag single blade

The scraper device is composed of a pneumatic thumb, a scraper body, and a swinging device. The core component is the pneumatic thumb, which is connected to the scraper body through a rotating shaft. The scraper blade is inserted in the middle of the pneumatic thumb knife magazine. The pressure of the scraper is pressurized by the pneumatic thumb. The two pneumatic tires and pressure relief are completed. The scraper body is used to fix the pneumatic thumb. It must have sufficient rigidity and straightness.
The double air-cell 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 airbag can make the contact between the blade and the roller at any point is very balanced, and prevent the roller from being scratched.
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 to 6mm, and the blade can be easily replaced.

Double air bag double blade

he double-blade device, made up by two air-cell blades, it means using two air-cell 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 device 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.
