The utility model relates to a mineral wool sandwich board PIR edge sealing production system which comprises a white material storage tank, a pentane storage tank, an on-line cutting precision mixer, a transition tank, a black material storage tank and a mixing head. Due to the fact that the using amount of edge sealing materials is small, the mixing effect of polyester and pentane is affected, and edge sealing sandwich boards with high fire resistance cannot be manufactured, the system cuts, extrudes, impacts and disperses white materials and pentane in the mixer by increasing flow feeding, and the mixing effect is improved. Due to the fact that the premixing white material amount consumed by the mixing head is small, discharging of the mixing head cannot be interrupted, and the output of the premixing white material is different from the premixing white material amount consumed by the mixing head, in order to achieve flow balance of the premixing white material and the premixing white material amount consumed by the mixing head, flow balance is achieved by increasing the premixing white material flow + intermittent feeding = small flow of the mixing head + continuous discharging. The middle transfer transition device caches the premixed white material to solve the problem of uninterrupted discharging of the mixing head so as to achieve continuous production, and the major problem that online mixing foaming cannot be achieved due to small flow of polyester and pentane is successfully solved.
