Similarly, the insulation board is sequentially transferred from the fourth coating machine to the fifth drying oven, the third coating machine, the fourth drying oven and the lifting platform on the other side, and the insulation board with the four side surfaces being coated with the polyurea base coat, the polyurea waterproof layer and the fireproof sand apparent layer is obtained. At least one supporting rod is respectively fixed on two opposite surfaces of the obtained heat insulation board, the supporting rods on two sides are placed on a bracket of a continuous production line, the upper end surface and the lower end surface of the heat insulation board can be continuously sprayed, and finally the composite heat insulation board with a five-layer structure on the cross section passing through any group of opposite surfaces of the board body subjected to all-dimensional spraying can be obtained.
When implementing the continuous production line proposed by the present application: the inclination angle of the table top can be changed by driving the second telescopic rod 13 to extend or shorten; the first telescopic rod 13 is driven to extend or contract, so that the height of the table top from the ground can be changed. At the moment, the tiltable lower table top is suitable for workers to conveniently and quickly arrange the heat preservation plate frame on the bracket. And driving the rotating mechanisms on the devices, transferring the heat-insulation boards from the lifting platform 1 to the board pretreatment device 2, and then sequentially transferring the heat-insulation boards to the first oven 3, the first coating machine 4, the second oven 5, the second coating machine 6, the third oven 7 and the lifting platform 1 on the other side. Staff adjusts the mesa low through ordering about first telescopic link 13 and second telescopic link 13, can take off thermal protection composite panel convenient easily.
It should be noted that the above-mentioned embodiments are exemplary, and those skilled in the art can devise various solutions in light of the present disclosure, which are also within the scope of the present disclosure and fall within the scope of the present disclosure. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims. The scope of the invention is defined by the claims and their equivalents.
