Product Description

Product Description

Reasonable doctor blade technology is very important in industrial processing applications. Reasonable doctor blade technology far exceeds the choice of the doctor blade. Scraper fixtures are also very important. The clamp must be able to reasonably position the scraper blade so that it closely adheres to the roller. To a certain extent, it can accept and accommodate the irregularity of the roller surface. It can be adjusted according to different thermal expansion degrees to facilitate frequent blade replacement. LEIZHAN's solutions provide a full range of doctor fixtures for most roller positioning and applications

Air-bag Type
The air-bag control form can give full play to the flexibility of the gasbag. The balanced contact with the roller surface prevents it from damaging the roller surface. The lineal pressure can be automatically adjusted by regulating the pressure of the source gas. The available blade is inflexible thickness and is easy to manage and replace. The roller will not be damaged when the blade is replaced, thus achieving high working efficiency. 

F-type
It is a kind of common blade holder in the paper-making industry. It is pressurized by self-weight and is operated with a handle. No source gas is needed. An air cylinder may be equipped to regulate and control the lineal pressure and the opening and closing of the blade. The contact pressure between the holder and the roller surface can be adjusted by fine-tuning the screw. 

Yankee Blade Holder for Cylinder Drying
The oil-pressure pipe within the holder can prevent the holder from deforming. It can be well attached to the blade, thus offering good stability. Besides, it uses low linear pressure and produces a high cleaning efficiency. The use of an air-bag blade holder enables the roller to fully contact the blade, thus offering favorable flexibility. No fine-tuning is required. In addition, the blade is of good rigidity and corrugates stably. It is able to provide 1,500~3,500N/m lineal pressure required by corrugation.
 

 

Features

1. Double airbag single doctor blade holder

• The airbag can make the contact of the blade and the roller at any point is very balanced, preventing the roller from being scratched.
• Adjust the pressure of the air supply through the pressure reducing valve, so that the line pressure can be effectively controlled.
• The thickness of the blade can be freely selected from 1mm to 6mm, and the blade replacement is convenient.

2. Double air bag and double doctor blade holder

• Install double doctor blade holder in the center press section and net section rolls. Due to the centrifugal force, the water and fine fibers in the hole of the vacuum pressure roller will not flow out and adhere to the roller doctor blade to destroy its surface tension, remove some water and fine fibers, and form a tiny negative pressure after the doctor blade to remove the water in the hole. After the fiber is completely discharged, it is cleaned by the second doctor blade.
• Prevent the net from regaining moisture and improve the dryness of the net. Experience has shown that after the vacuum roll uses pneumatic tire pressurized double doctor blade holder, the paper output dryness of the wire can be increased by 10-25%, and the investment cost can be recovered in a short time. At the same time, it can ensure the cleaning in the roll hole and the water content of the paper banner of the wire. Uniformity; the use of pneumatic tire pressure double doctor blade holder on the right roller of the press can thoroughly clean the water and fine fibers on the roller surface to prevent paper breaks and paper defects.
• The double doctor blade holder is divided into ABCD double doctor blade holder and ABC CM type double doctor blade holder. We will design according to the customer's specific situation and provide customers with choices.

3. Wrinkle air bag type doctor blade holder for Yankee

• The choice of Yankee type wrinkle doctor blade holder using ABC airbag type doctor blade holder fixture, the roller has good contact flexibility with the doctor blade holder in full width. No detailed adjustments are required. Moreover, the doctor blade holder has good rigidity and stable wrinkling. It can stably provide the 1500~3500N/m line pressure required for wrinkling.
