Paper Machine Felt Fabric Guider Control Sensor

The signal sensor is the brain of the pneumatic guider, which consists of a rotating shaft (baffle, roller, turntable) in contact with the felt fabric and an air valve that controls the flow of compressed air. Sun Hong's guider sensor are suitable for paper machines with different speeds ranging from 20m/min to 2000m/min. We provide three materials : copper, stainless steel, and aluminum, and the key parts are made of wear-resistant materials.

Working principle of Felt & Fabric Signal Sensor

Compressed air from the pipeline enters the control valve after the pressure is adjusted by the pressure reducing valve. When the mesh is shifted to the right, the shaft also moves to the right with the felt & fabric. This reduces the tension of the spring, increasing the pressure of the switching valve and reducing the pressure on the other side, causing a pressure difference between the two ends of the actuator cylinder, pushing the piston and driving the guide roller to move forward, correcting the felt & fabric to the left. Conversely, when the felt & fabric moves too much to the left, the shaft also moves to the left, increasing the tension of the spring. The pressure of the switching valve decreases, and the pressure on the other side increases, causing the actuator to drive the guide roller to move backward, correcting the felt & fabric to the right.

Pneumatic Control Box

Different types of guider can be selected based on different temperatures and usage locations (such as dry or wet areas). Different guider can also be equipped with different pneumatic control boxes.
