The pneumatic scraper swinger is an important part in the papermaking production line. By driving the scraper to reciprocate, it can effectively clean the impurities on the roller surface or cylinder surface and ensure the quality of paper production. It has played an important role in the domestic papermaking production line, as follows:
Working principle: The pneumatic scraper swinger is usually powered by compressed air, and is internally provided with a reversing valve and a double air cavity. By controlling the air intake and exhaust of the air cavity, the piston shaft is driven to perform continuous bidirectional swinging motion, and then the scraper body connected with it is driven to reciprocate along the axial direction of the drying cylinder or roller, so that axial shearing force is generated between the scraper blade and the cylinder surface or roller surface to remove surface dirt.
Performance advantages:
Adaptable to harsh working conditions: imported ultra-high temperature resistant seals, imported stainless steel and copper as the whole material and coated on the surface, can work in the high temperature environment of 180℃, and can adapt to the harsh environment with acid-base water mist in the screen pressing part.
Simple maintenance: relatively simple structure, no dynamic wear, little maintenance and low failure rate. Its control valve is integrated under a sealed protective cover, and the air connection adopts a single air connector, which simplifies the installation, operation and maintenance.
Stable operation: it can provide accurate and stable uniform oscillation, compensate the change of bearing force when the bearing is worn, ensure that the scraper always keeps a good contact with the roller surface or cylinder surface, and effectively remove impurities.
Energy saving and environmental protection: clean air is used as the power medium, which reduces the energy consumption of the factory, is safe and reliable, and has no pollution and harm to the environment.
Help the development of papermaking production line;
Improve production efficiency: the pneumatic scraper swinger can make the scraper fit the roller surface or cylinder surface better, effectively solve the problems of pulp winding on the roller surface and pulp accumulation in the scraper, reduce the downtime caused by equipment failure, and improve the operation efficiency of the paper production line, especially in high-speed paper machines.
Improve product quality: By continuously and steadily driving the scraper to clean the impurities on the roller surface or cylinder surface, it can prevent the accumulation of dirt, avoid the quality problems such as holes and spots on the paper, ensure the uniform and smooth surface quality of the paper, and improve product quality.
Reduce the production cost: because it reduces the wear of rollers and other parts, it prolongs the service life of equipment, reduces the frequency of equipment maintenance and replacement, and then reduces the related maintenance cost and downtime loss, which is helpful to reduce the production cost of paper-making enterprises.
