Further, the distance between the forming roller and the supporting roller is matched with the thickness of the leather base material.
Further, heating mechanism is including setting up at leather substrate transfer chain outlying portal frame, forming a plurality of infrared heating head on the portal frame, still be formed with the switching piece on the portal frame, the switching piece has the inclined plane, a plurality of infrared heating head set up on the inclined plane and with the shaping roller is corresponding.
Further, heating mechanism is a plurality of heating strip for setting up on the shaping roller stack shell, heating strip and a plurality of trompil are the setting of staggering.
After the technical scheme is adopted, the utility model relates to a vacuum heating roller device for leather-making, creatively heats the foaming material layer, be in under the condition of softened state at the foaming material layer, recycle vacuum generator forms the negative pressure in the cavity, utilize this negative pressure to attract the foaming material layer after softening, under the dual function of the trompil of extrusion force and stack shell, let the foaming material layer take place the extension, and the shaping goes out outside convex protruding grain, these protruding grains have reached the effect of imitative ostrich skin in the appearance, thereby let ostrich artificial leather's machine-shaping become the reality.
Compared with the prior art, the utility model discloses a realized that vacuum adsorption's mode reaches the purpose of imitative ostrich skin, improved production efficiency greatly, also ensured the quality of product.
