[0002] Agricultural film is a common plastic product used to cover farmland. It helps to increase ground temperature, maintain soil moisture, and promote seed germination and rapid growth of seedlings. After being extruded through a melt extruder, agricultural film is prone to deformation due to its high temperature. Therefore, the extruded film needs to be cooled and shaped.

[0003] The existing Chinese patent with announcement number CN206217149U discloses a device for rapid cooling and shaping of plastic products. The above-mentioned existing technical solution has the following defects. Although the above-mentioned technical solution can remove the cooling water remaining on the surface of the plastic agricultural film while cooling and shaping the plastic agricultural film, thereby preventing the cooling water remaining on the surface of the plastic agricultural film from affecting the next plastic agricultural film packaging process and speeding up the production speed of the plastic agricultural film, in the above-mentioned technical solution, the cooling water is sprayed out by a spray head to spray and cool the plastic agricultural film, which can only spray and cool one side of the plastic agricultural film and cannot cool the plastic agricultural film in all directions. Therefore, it is easy to reduce the cooling and shaping effect of the plastic agricultural film, thereby easily reducing its processing quality. Utility Model Content
