Benzene board equipment - fully automatic foam sheet forming machine characteristics

　　It is made of high-quality section steel by welding and aging heat treatment. The machine has high strength, no deformation and can bear the expansion force of high-density products.

　　The electrical part adopts the advanced programmable logic controller (PLC) control system to ensure the stability and reliability of the electrical system and reduce the failure probability in the process of machine operation.

　　Hydraulic system is used to control mold opening, mold closing, ejector and mold locking. Compared with the pneumatic device, the hydraulic system has the characteristics of stability, high pressure and incompressibility, so it has less faults, large clamping force and reliability in operation, and there will be no serious leakage in operation. This can reduce energy consumption and improve the production environment; At the same time, the production efficiency can be increased by 3% ~ 10%.

　　Using automatic feeding gun and negative pressure feeding, the production efficiency is improved, and the plate density is uniform and the appearance is flat and smooth.

　　The steam control system adopts automatic ball valve control, which makes the performance of the machine more stable, safe and longer service life.

　　All pipelines are automatically controlled, with multiple automatic safety protection measures such as overpressure alarm and automatic pressure reduction, as well as three-level protection measures such as computer monitoring, pressure feedback and automatic exhaust of electrically controlled full open safety valve.

　　The hydraulic cylinder is used to open the die cavity from the front side, and the plate is pushed laterally, which saves nearly half of the working area than pushing the plate from the length direction. Only one side of the mold cavity is opened to reduce steam leakage, which not only saves energy, but also is conducive to product molding, and increases the safety factor of the equipment.

　　The expandable polystyrene penetration molding process is adopted, which is heated and insulated for three times. It has the characteristics of strong penetration ability, good adhesion, fast molding speed, less gas consumption, flat plate surface and energy saving.

　　The operation program of the machine is jointly controlled by computer, hydraulic and pneumatic to realize full automation, so that the program action of the machine is accurate, reliable, safe and efficient. Each program can work according to the preset time and analog input signal, and automatically transfer to the next program. Therefore, it can produce plates with different densities in the range of 4 ~ 35kg / m3, and has the ability to adapt to different process requirements. One machine is multi-purpose and one machine is multi-functional.
