s6: under the condition of a certain feeding amount, the inclination of the upper surface of the foaming sponge 10 positioned at the front section of the foaming gallery 1 tends to be stable, and an included angle between the inclined upper surface of the material and the horizontal plane is defined as B1;
s7: because the foaming sponge 10 at the front section of the foaming gallery 1 is a thick substance with high fluidity, the top surface of the thick substance is of a cambered surface structure; in the foaming process of step S6, the radian of the arc surface is observed by naked eyes, and when the radian is too high, the angle adjusting guide rod 71.1 is adjusted upwards to lift the films 72 at the two ends of the foaming sponge 10 upwards, so as to increase the heights of the edges at the two ends of the thick object, and as the films 72 are lifted, the top surface of the thick object tends to a plane, and the top surface of the thick object tends to a plane by naked eyes; at the moment, the included angle between the angle adjusting guide rod 71.1 and the horizontal plane is recorded and defined as A2;
s8: keeping the angle of A2 unchanged, attaching the film 72 to both sides of the foaming sponge 10 and driving with the foaming sponge 10, and finishing the one-time foaming work when the foaming sponge 10 is fully distributed in the whole foaming corridor 1.
As shown in FIG. 6, the cutting line is used as a reference surface, more sponge blocks need to be cut, and the sponge is wasted due to the fact that the radian of the top surface of the sponge is large and the sag H is long.
As shown in figure 7, by adopting the side film lifting device in the technical scheme, the sag H can be reduced, the top surface of the sponge tends to be flat, the sponge to be cut is less, the height of the effectively used sponge block can be increased, and the quantity of finished products is increased.
