[0032] The cooling component includes an air collecting tube 7 , the interior of which is provided with evenly distributed air outlets 18 , a connecting pipe 6 is fixedly connected to the left side of the air collecting tube 7 , one end of the connecting pipe 6 is fixedly connected to a fan 5 , and the fan 5 is fixedly connected to the upper part of the extrusion box 4 .
[0033] The raw material is blown out through the extruder head 22 to form a plastic bag. At the same time, the fan 5 is started to allow the wind to enter the interior of the air collecting tube 7 through the connecting pipe 6, and the plastic bag is cooled without dead angles through the air outlet 18 to prevent it from sticking together during winding.
