Research And Application Of Continuous Glass Fiber Mat Doffing System

Glass fiber continuous mat is a new type of composite reinforcement material that is widely used.It is made up of multiple glass fiber strands as a bunch of glass fibers,which are distributed freely on the matrix material,and the multiple glass fibers are overlapped and laid flat,and then stitched or bonded by an adhesive to form a flaky product.It is widely used in the FRP production field.In order to adapt to the industrial use environment,and there is high requirement for isotropy of glass fiber continuous mat in industrial production.To achieve this requirement and process continuous mats that satisfy the requirements,it is necessary to design a device that guides the movement of continuous glass fiber filaments,build a doffing system,and ensure that the continuous glass fibers are evenly distributed on the mesh belt through accurate control.The research content of this paper includes the following parts: Analyzed the research background and development status of continuous glass fiber continuous mat production technology,and explained the direction and significance of the subject research;According to the production process and the specific requirements put forward by the cooperative unit,design the mechanical structure scheme design and overall control scheme of each part of the doffing equipment,and a reasonable design scheme was determined;Design the specific mechanical structure,select and check the components and action components of each actuator,and use 3D drawing software to model and simulate;Set up a control system with programmable controller as the core controller,calculate and allocate input and output ports,and select the corresponding hardware modules,according to the control requirements of the actuators,draw the wiring block diagram of the system,the main circuit diagram of the system and control principle diagrams of relevant actuators,and complete the assembly and wiring of the control cabinet according to the drawings;Construct a control and monitoring system composed of PLC and master computer,write effective control programs to ensure the stable and safe operation of the doffing system,and use configuration software to develop a human-computer interaction interface to effectively achieve the real-time monitoring of the doffing system.The continuous fiberglass mat production line equipped with this doffing system can produce and process a variety of continuous fiberglass mats with standard widths and weight specifications.The doffing equipment designed in this subject optimizes the mechanical structure and control system of the doffing and felting equipment,and provides a new idea for the design of continuous felt production equipment.
