Seiko Landing, Empowering Research and Development of New Materials | Suzhou Zhanheng Intelligent POY Spinning Testing Machine Successfully Completed Installation and Commissioning

Recently, the POY spinning testing machine independently developed and manufactured by Suzhou Zhanheng Intelligent Technology Co., Ltd. successfully completed the installation of the whole machine, system debugging and trial spinning, and all the process indicators reached the design standards, successfully achieving the start-up and trial operation. The successful completion of the equipment delivery and commissioning indicates that Zhanheng Intelligent's complete set delivery capability in the field of chemical fiber experimental equipment has been continuously consolidated, which can provide a stable and reliable pre-oriented yarn research and development test platform for universities and new material enterprises, and help the rapid development and process verification of differentiated fibers and new polymer filament materials.

POY pre-oriented yarn is a basic filament product in chemical fiber industry, which is widely used in textile and garment, industrial textiles and other fields. POY spinning testing machine is mainly used in laboratory and pilot stage, simulating the whole process of industrial melt spinning, completing melt extrusion, metering and distribution, spinning, cooling by side blowing, oiling, bundling and high-speed winding of polyester, polyamide, polylactic acid and other polymer chips, helping R&D personnel to quickly explore process parameters such as formula, temperature, pressure and winding speed, evaluating the performance of finished fiber products under small batch conditions, greatly shortening the period from laboratory research to industrialization landing, and effectively reducing the risk of industrial trial production. As the core precision equipment of chemical fiber research and development, this equipment has strict requirements on installation accuracy, environmental control and system coordination. Any slight installation deviation will directly affect the forming stability and fiber index uniformity of tow.

Since the start of this project, Zhanheng Intelligent has set up a special technical service team to carry out on-site survey and technical disclosure in advance, and formulate a detailed implementation plan for equipment entry, hoisting in place, pipeline wiring and debugging in combination with the space layout of the customer's laboratory, floor bearing, power supply and gas supply, and clean conditions of temperature and humidity. In the installation and implementation stage, the technical team completed the leveling and positioning of the main engine base, the extruder, the spinning box, the metering pump, the side blowing cooling unit, the oiling system, the guide wire mechanism and the precise assembly of the high-speed winding head in strict accordance with the ISO9001 quality management standard. In the pipeline and electrical construction, the melt pipeline and air pipeline are sealed, and the temperature, pressure and speed sensors are checked and shielded to avoid potential risks such as signal interference, melt leakage and wind field fluctuation. Self-inspection and recheck are carried out in each process to ensure that the mechanical coaxiality and levelness meet the technical specifications of precision spinning equipment.

After the main equipment is installed in place, the project enters the stage of fine debugging, and strictly follows the three-level debugging process of "single machine no-load debugging, system linkage debugging and raw material load trial spinning". In the no-load stage, technicians conduct power-on detection on each independent unit one by one, check the PLC control system, man-machine interaction interface, alarm and safety interlock functions, test the temperature control accuracy of multi-stage heating module of extruder, calibrate the melt conveying stability of metering pump, check the running status of start-stop, commutation and tension control of winding system, troubleshoot abnormal transmission sound, jamming and parameter drift, and repeatedly calibrate key parameters such as temperature, pressure and wind speed to ensure the stable and reliable independent operation of each unit.

After the no-load verification is completed, the project is transferred to the whole system linkage debugging, and the complete process link from raw material feeding to silk cake winding is opened. Technicians gradually optimize the distribution of lateral blowing temperature, wind speed and wind pressure, debug the oil tanker speed and oil supply flow, match the guide wire path, and eliminate the hidden dangers of tow jitter, drifting and broken wire. In the trial spinning process, polyester chips are selected to carry out the actual spinning test, and the core process parameters such as extrusion temperature, melt pressure, metering pump output and winding speed are continuously fine-tuned, and the key indicators such as tow appearance, size uniformity, breaking strength and elongation are monitored in real time. After several rounds of parameter iterative optimization, POY precursor with stable molding and uniform index was successfully produced by the equipment, and the state of continuous long-term trial operation was stable, and all technical parameters met the requirements of customers for new material research and development.

At the final stage of commissioning, Zhanheng Intelligent Technology Team simultaneously conducted on-site operation training, and explained the equipment principle, process flow, parameter setting, daily maintenance points, common fault identification and emergency treatment methods to customers' R&D personnel, so as to help customers quickly master the equipment operation ability and ensure the subsequent independent material test. At the same time, the project team completed the handover of complete sets of equipment drawings, operation manuals, calibration records and process reference documents, and established a long-term technical service docking channel to provide continuous support for subsequent process iteration, equipment maintenance and upgrading.

As a high-tech enterprise deeply involved in the field of chemical fiber intelligent experimental equipment, Suzhou Zhanheng Intelligent focuses on the research and development, manufacturing and complete delivery of spinning testing machines and high-performance fiber pilot equipment, and has the integrated service capability from scheme design, equipment manufacturing, on-site installation and debugging to technical training. Companies continue to adhere to independent technological innovation, relying on modular equipment architecture and high-precision process control system, to create spinning test equipment that meets the research and development needs of different polymer materials. The products can cover a variety of new material development scenarios, such as conventional polyester nylon, bio-based fiber and functional modified fiber, giving consideration to test flexibility and data repeatability, helping customers reduce research and development costs and accelerate the transformation of new material achievements.

The successful installation and debugging of POY spinning testing machine project is another practical verification of the technical strength and field service ability of Zhanheng intelligent equipment. In the future, Suzhou Zhanheng Intelligent Technology Co., Ltd. will continue to optimize POY, FDY, BCF and high-performance fiber series test equipment based on the development needs of chemical fiber new material industry, constantly polish the product stability and intelligence level, deepen the collaboration with Industry-University-Research of scientific research institutes and new material enterprises in universities, empower fiber material innovation with precision experimental equipment, and continuously contribute to the high-quality development of domestic synthetic fiber industry.
