A flow-guided mixing head for a polyurethane foaming machine

Abstract

The utility model relates to polyurethane foaming machine technical field discloses a guide formula mixing head for polyurethane foaming machine, including the connecting head, the outside of connecting head is provided with several groups of needle valve. That is used for polyurethane foaming machine's guide formula mixing head, through the setting of air inlet subassembly, when using, after the material enters needle valve, the on-off of blast pipe is realized through the accurate control of solenoid valve, and the blast pipe imports gas to needle valve inside immediately, and the pressure gauge real -time monitoring the air pressure situation in blast pipe to guarantee air pressure stability, and the stable air pressure can form the even boost and flow rate regulation and control to the material in needle valve, effectively avoid the problem of uneven flow rate caused by material viscosity change or pipeline resistance fluctuation, and the material enters the inside of mixing pipe with consistent flow rate steadily, so that the quantity of material is consistent when entering the inside of mixing head, thereby ensuring the uniformity and stability of subsequent foaming process.
