The anti-blocking technology and pipeline inner wall treatment process of servo gob feeder directly affect the continuous and stable operation of the equipment.
In industrial production, servo gob feeder is responsible for accurately conveying various materials, but the material characteristics and various factors in the conveying process can easily lead to pipeline blockage, affecting production efficiency and product quality. Anti-blocking technology and pipeline inner wall treatment process are the core to ensure the stable operation of servo gob feeder. In-depth research on the two is of great significance to improving equipment reliability and reducing maintenance costs.
The reasons for servo gob feeder blockage are complex and diverse. From the perspective of material characteristics, materials with high viscosity, high humidity or uneven particles are prone to adhesion and accumulation in the pipeline; some materials agglomerate due to moisture absorption and chemical reactions, causing blockage. In terms of equipment operation, unstable feeding speed and unreasonable design of pipeline bends will hinder the flow of materials; after the servo gob feeder has been running for a long time, the inner wall of the pipeline will be worn and the residual material will solidify, which will gradually reduce the inner diameter of the pipeline and eventually cause blockage. In addition, changes in environmental factors such as temperature and pressure may also increase the risk of blockage.
Blockage can be effectively prevented through mechanical structure optimization. Adopt variable diameter pipeline design, appropriately expand the pipe diameter at the parts prone to blockage (such as feed inlet and bends) to reduce the material accumulation pressure; set guide vanes or spiral conveying structures inside the pipeline to force the material flow and prevent stagnation. In addition, design a detachable pipeline module to facilitate regular cleaning and maintenance; install a vibration device at the pipeline outlet to keep the material in a loose state through high-frequency vibration to reduce the chance of blockage.
The characteristics of the inner wall material of the pipeline directly affect the adhesion and flow of the material. Choose low surface energy materials, such as polytetrafluoroethylene (PTFE), which has a smooth surface and strong non-stickiness, which can reduce the adhesion of materials to the pipe wall; ultra-high molecular weight polyethylene (UHMWPE) has excellent wear resistance and self-lubricating properties, which can reduce material transportation resistance and extend the service life of the pipeline. For corrosive materials, stainless steel lined or ceramic coated pipelines are used, which can not only prevent corrosion but also ensure the smooth inner wall to avoid blockage caused by material loss.
The surface treatment process further enhances the anti-blocking performance of the pipeline. Through electroplating, chemical plating and other methods, a dense metal coating, such as chrome plating and nickel plating, is formed on the inner wall of the pipeline to improve the surface finish and wear resistance. Nano-coating technology is used to construct a nano-scale microstructure on the surface of the pipe wall, and its special surface tension characteristics are used to make it difficult for materials to adhere. In addition, plasma treatment can change the surface chemical properties of the inner wall of the pipeline, increase hydrophilicity or hydrophobicity, adjust the surface wettability according to the material characteristics, and optimize the material flow performance.
Introduce intelligent monitoring and automatic cleaning technology to achieve dynamic management of anti-blockage. Install pressure sensors and flow sensors at key parts of the pipeline to monitor the material conveying status in real time. Once abnormal pressure, decreased flow rate and other signs of blockage are found, the system will immediately alarm and automatically adjust the feeding parameters. Combined with automatic cleaning devices, such as built-in cleaning brushes and high-pressure gas purge systems, residual materials on the pipe wall can be removed in time at the early stage of blockage; some advanced servo gob feeders are also equipped with ultrasonic cleaning functions, which use high-frequency vibrations to disintegrate stubborn materials attached to the pipe wall.
The anti-clogging technology and pipe inner wall treatment process of servo gob feeder are systematic projects, which require comprehensive mechanical structure optimization, material innovation, surface treatment and intelligent technology application. As the requirements for automation and continuity in industrial production continue to increase, anti-clogging technology will develop in the direction of intelligence and adaptation in the future. Through the research and development of new materials and process innovation, more efficient and stable material transportation can be achieved, which will further promote the improvement of manufacturing production efficiency.
