And if the wind speed and the wind volume do not meet the requirements, simultaneously opening the electromagnetic valve and the high-pressure spray nozzle 35.
Moreover, when the surface to be dried is large, the drying area needs to be enlarged, so the second cover 32 is provided with a folding structure, and the length of the second cover in the vertical direction is variable, so that the length of the second cover 32, that is, the size of the drying area can be adjusted according to actual requirements;
According to a preferred embodiment of the present invention, a plurality of limiting rods 37 are vertically arranged in the second cover body 32 at intervals, the limiting rods 37 in the second cover body 32 of the two heating devices are respectively in one-to-one correspondence and are correspondingly arranged, and a certain distance is arranged between the two corresponding limiting rods 37, so that the semi-finished lawn can pass through the distance.

According to a preferred embodiment of the invention, the glue is prepared from the following raw materials in parts by weight:
according to a preferred embodiment of the invention, the foaming agent is any one of sodium dodecyl sulfate, fatty alcohol-polyoxyethylene ether sodium sulfate, rosin soap foaming agent and animal and vegetable protein foaming agent; the thickening agent is a cross-linked polymer emulsion thickening agent containing acidic groups.
