Product Description


Paper Machinery Parts Making Machine Stainless Carbon Steel Ceramic Glass Fiber HDPE Epoxy Resin Coating Cleaning Cutting Circle Phosphor Bronze Doctor Blade

Once in the maintenance period, the doctor blade is usually easily ignored. But some simple routine maintenance can keep the equipment running efficiently.One of the most effective ways to check the same problem is to check the blade with vision. The following table shows the different types of blade wear and the corresponding treatment methods. This inspection method is very effective.

Problem Reason Measure
Uneven wear, frequent blade replacement 1. The surface of roller or dryer is uneven
2. The doctor holder is damaged or dirty
3. Sediment
1. Use a softer blade
2. Clean, repair or replace the doctor holder
3. Use abrasive blade
Excessive wear on middle or edge of blade 1. The blade is not installed on the top of the roller
2. The old blade sinks (or leaves) the roller or dryer
1. Refit or add gasket at the back of blade if necessary
2. Replace the old and sunken blade
Excessive wear at one end of blade The displacement of blade is not parallel to the axial direction of roller or dryer Add gasket, if necessary, move bearing and bracket to adjust scraper parallel to axial direction
The blade is worn evenly, but the end face is rough 1. There is deposit on the surface of roller or dryer
2. The pressure of blade is too high
3. The material of blade is too hard
1. Use abrasive blade when necessary
2. Reduce the pressure
3. Use a slightly soft blade
Excessive wear in sheet area The sheet leaves sediment on the roller or dryer 1. Use abrasive blade when necessary
2. Trim the edge of blade frequently
3. Use blade with slotted end to prevent excessive pressure on both ends of roller or dryer
Excessive wear out of sheet area The sheet lubricates the roller or dryer Use blade with slotted end
Local depression The blade is damaged, electrostatic (discharge/ electrolysis /heating) Insulate the blade from the holder or use a non-metallic blade
The blade produces burr 1.The material of the blade is too soft
2. The pressure is too high
3. The angle of the blade is too small
1. Use a slightly hard scraper
2. Reduce the pressure
3. Adjust the bearing or bracket to increase the angle, and use the instrument to check and correct the angle

Function

Although the doctor blade seems to be a set of simple paper machine equipment, and the investment is not large, its role is not small at all. It can keep the paper machine rollers and fabrics (forming fabric, press felt, dry fabric, etc.) clean, extend the cleaning cycle and fabric service life of the paper machine, maintain the normal operation of the paper machine and the stability of paper quality, so as to produce huge benefits.

Principle

Paper Machinery Parts Making Machine Stainless Carbon Steel Ceramic Glass Fiber HDPE Epoxy Resin Coating Cleaning Cutting Circle Phosphor Bronze Doctor Blade
The blade removes contaminants and water from the roller / dryer surface by holding the blade in a fixed position and swinging back and forth under the same pressure, such as swinging on the smooth press roll to remove debris due to paper surface breakage.

Classification and Features

Paper Machinery Parts Making Machine Stainless Carbon Steel Ceramic Glass Fiber HDPE Epoxy Resin Coating Cleaning Cutting Circle Phosphor Bronze Doctor Blade
Classification
Doctor blade is a common mechanical device in paper machine, which can be divided into two types: one is the blade used for cleaning such as rolls (including the roller of net / press section, dryer cylinder ); the other is functional doctor blade, such as coating blade and creping doctor.

Features
1.Triple tempt for optimum wear resistance.
2.Long service life for an extra clean cut of tissue paper, toilet roll.
3.Precise heat treatment.
4.Excellent cutting longevity and wear resistance.
5.High intensity,high toughness,small thermal deformation.
6.Blades are eliminated unwanted and uncontrollable residual stress.
