[0002] Roto-molding, also known as rotational molding, rotational molding, rotational molding, etc., is a thermoplastic hollow molding method. The method is to first add the plastic raw material into the mold, and then the mold is continuously rotated along two vertical axes and heated. Under the action of gravity and heat energy, the plastic raw material in the mold is gradually and evenly coated, melted and adhered to the entire surface of the mold cavity, forming into the required shape, and then cooled and shaped into a product. In the production and processing of environmentally friendly plastic runway materials, a roto-molding machine is required to perform roto-molding on the environmentally friendly plastic runway materials.

[0036] like Figure 2 As shown, a fan is provided inside the blowing cover 47 .

[0037] A fan is arranged in the blowing hood 47 to blow moisture from the material side and accelerate the cooling and heat dissipation of the material.

[0038] The following is a detailed description of the working principle of the rotational molding machine used in the production of environmentally friendly plastic track materials.
