The "dust collection device" is a device designed to remove foreign substances that have been removed by the doctor device. The doctor device is installed for the purpose of removing foreign substances from the roll, so it naturally generates foreign substances that are removed by the blade. Depending on the installation condition of the doctor device, foreign substances may accumulate on the blade surface or in the catch pan. Accumulated foreign substances can sometimes fall into the line as large clumps, potentially causing issues such as scratches. To break this negative cycle, this dust collection device has been developed. This device automatically removes foreign substances, preventing their accumulation and allowing for a longer maintenance cycle for the doctor device. 【Features】 ■ Automatically removes foreign substances ■ Prevents accumulation of foreign substances ■ Allows for a longer maintenance cycle for the doctor device *For more details, please refer to the PDF materials or feel free to contact us.

The "Oscillation Device" is a device that periodically slides the main body of the doctor device. The doctor device is used to remove foreign substances from the roll, so the doctor blade must always be in contact with the roll, which is a rotating body, for its intended purpose. However, as the doctor device is used, foreign substances removed by the blade can accumulate at the blade tip, potentially adversely affecting the roll. Such a situation can be resolved by periodically sliding the entire blade. Additionally, by operating the oscillation device, the wear of the entire blade can be equalized, resulting in an extended blade lifespan and a stable doctoring effect. 【Features】 ■ Prevents accumulation of foreign substances at the blade tip by allowing the blade to constantly slide laterally ■ Equalizes wear across the entire blade ■ Extends the lifespan of the blade ■ Achieves a stable doctoring effect *For more details, please refer to the PDF document or feel free to contact us.

We will introduce an example of a blade holder that has been divided using a double air tube method. By using a split blade holder, it is possible to control the doctor ring more precisely. 【Example】 <Triple Split with Double Air Tube Method> ■Merits of splitting the pressurized air tube - Since the pressurized air tube can be split and controlled individually, it is possible to change the line pressure of the blade between the center of the roll and the left and right sides. - Even when the roll crown is large, it can follow without increasing the overall line pressure of the blade, allowing for a significant doctor ring effect with minimal burden on both the blade and the roll. - The blade is made from a single piece, so the joint part of the holder split can also smoothly create a doctor ring. *For more details, please refer to the PDF materials or feel free to contact us.
