In general, if there are quality problems with industrial brushes, it is usually due to obvious quality issues with the bristles (such as broken threads, hair removal, etc.). However, in addition to identifying the quality of the bristles, it is also necessary to analyze the processing technology. Common case analyses are as follows:

1. The density of bristles is low. Some brush manufacturers, in order to save on wire costs, have few bristles per hole or insufficient brush hole density, resulting in sparse overall bristle volume on the brush roller, soft and weak bristle surface, low grinding efficiency, and unknown reasons for users to increase back pressure or speed to improve efficiency. As a result, the bristles are overloaded and their lifespan is greatly reduced.

2. Brush and plant hair tilted. When pressing U-shaped metal strips, special attention should be paid to whether the bristles are smooth. If there is cross tilting, the resistance of the bristles in the opposite direction will increase significantly during the operation of the brush roller, which is prone to breakage and greatly reduces the service life of the brush roller.

3. The brush sheds (breaks) hair. There are mainly two situations: single bundle shedding and local shedding (breakage) of hair. Single bundle hair removal is due to poor stability of hair transplantation, which is mainly related to the size of the drill hole, the number of hair grafts, the depth, and the number of hair roots. Generally, it can be detected by tensile testing of a single bundle of hair; Local hair removal is mainly caused by broken hair, which is mainly related to the dynamic balance of the brush roller, the quality of the bristles, and the quality of the planted (pressed) hair (density, inclination, pressure damage, resin curing, etc.). Through careful observation, the crux of the problem can be identified.

4. Processing crushed bristles. When the bristles are damaged during hair planting or stamping, their strength and durability are greatly affected, or if the contact surface at the root of the bristles is very sharp or rough, the durability of the bristles will also be reduced, shortening their service life.

5. Brushing and trimming hair is too long. When the length of the brush filament is too long, it is not the cutting surface of the brush filament that is working, but the side of the brush filament that is working. More importantly, the amplitude (angle) of each wire swing increases significantly. At 800-2500 revolutions per minute, the stress and fatigue coefficient of the brush filament foundation multiply, leading to abrasive brush filament breakage and brush roller deformation.

6. Differences in processing techniques. Sometimes brush makers use their familiar techniques instead of other processes, which can also result in poor quality. For example, metal stamping brushes have a higher density and harder brush surface, resulting in lower pressure during use. Additionally, there is a small amount of space for the bristles to move at the root, which can reduce the impact force at the root. In pneumatic mechanical processing, the service life of the brush is significantly longer than that of the bristle processing brush.

2、 The application of industrial brushes in the textile industry

The textile industry can use a variety of brush products, and the main types of industrial brushes include the following: setting machine brush wheel, grinding machine brush, brush machine brush, combing machine brush, brown brush, fine yarn machine brush, grinding machine brush, and polishing cloth wheel.

Flocking machine brush roller

Among them, the singeing machine uses brush rollers made of bristles such as pig bristles or nylon, and the roller shaft is injection molded with 45 # round steel. The woven fabric has a lot of excess fur, and the purpose of the singeing roller is to brush out these excess fur. There is an open flame below the brush roller to burn off these fur.

In addition, there is another type of brush that is the opening roller of the slitting machine. The slitting roller is made of 45 # round steel roller shaft and bristles made of nylon and other materials. The bristles are planted in a zigzag pattern from the middle to both sides. The brush roller feeds the fabric into the roll, and the zigzag pattern is used to brush the fabric on both sides to make it straight; Needle plate edge pressing brush wheel, with an injection molded body in the middle and mostly bristles made of pig bristles, is used to press the fabric edge onto the needle plate of the machine through the pressure of the bristles.
