- Automatic packaging and stacking system improves transportation safety, reduce manual intervention, and improve efficiency.
Detailed explanation of machine components
Two well-designed hydraulic unwinders, each capable of supporting a 55-ton weight, are attached to a movable trolley to facilitate the effortless unwinding of coils of raw materials. The movable trolley with equipment not only boosts operational flexibility but also significantly enhances productivity.
Dual roll forming machines: An essential piece of machinery on the manufacturing line are these two roll forming machines. The raw components are transformed into polyurethane boards with predetermined sizes and forms using a precision rolling process. The equipment’s steady functioning guarantees the items’ excellent quality and uniformity.
A high-pressure polyurethane foaming machine is the main tool used in the manufacture of polyurethane boards. To make sure the liquid polyester material is thoroughly combined and foams with other additives, high-pressure technology is used. Its self-cleaning system’s nozzle head successfully avoids blockages and guarantees the stability and continuation of output.
Host: In charge of directing and coordinating the actions of every partofn the production line, the host serves as its central control unit. It incorporates sensor technologies and sophisticated control algorithms to guarantee the stability and effectiveness of the whole manufacturing process.
PLC control system: The manufacturing line is powerfully managed and controlled by the sophisticated PLC control system. Operators may simply establish settings, check operational status, and achieve automated production using an easy-to-use operation interface.
Servo motor cutting system: Accurate cutting of polyurethane panels is ensured by the cutting system’s high-precision servo motors. The system can cut materials of various sizes and requirements quickly, accurately, and steadily.
