If the user wants to improve the use efficiency of the soft surface layer polyurethane composite board production line equipment, it is also very important to understand the supporting composition of the soft surface layer polyurethane composite board production line equipment.
The soft surface layer continuous pu sandwich panel line equipment is mainly composed of soft surface layer unwinding system, high pressure foaming system, double crawler system, double crawler heating system, cutting system, electronic control system and other equipment. The composition of these systems and equipment can help the system Improve overall operating efficiency.
The soft surface layer unwinding system of the soft surface layer polyurethane sandwich panel production line is installed on the platform, which can automatically position and control the soft surface layer material.
The feeding system is pneumatic charging, which can temporarily store the roll paper, and can provide a certain tension to the soft paper pulled by the double belt, so as to improve the production efficiency of the polyurethane sandwich panel production line system.
The high-pressure foaming machine mainly includes the following parts: low-pressure feeding device, isocyanate pipeline, polyol pipeline, pneumatic control circuit, polyol mixture pipeline, high-pressure mixing head, etc., which can send foaming and provide effective foaming quality , to improve the curing efficiency of the product.
It is mainly to overcome the foaming pressure generated by polyurethane foaming, thereby speeding up its curing and forming, which can determine the thickness of the composite board and the speed of the pu sandwich panel line.
Using this system can also avoid sheet deformities and scratches and improve the quality of composite sheets. The dual track temperature control system adopts hot air circulation heating, which is sent into the heating air duct by the fan. It can be used to heat the upper and lower track panels that move forward at a constant speed, so that the polyurethane foam is foamed and cured more stably, and the foam can be bonded to the surface of the board. Firmer, making the quality of the foam more high-quality.
According to the required board length parameters, under the premise that the production line of polyurethane sandwich panels does not stop, the finished board is automatically and continuously cut.
The control system of the pu sandwich panel production line is the information heart of the production line, which can ensure that the polyurethane sandwich panel production line can run synchronously with other units, which is convenient for operation.
