[0019] Start the extrusion blower 3, which extrude the melted blow molding material, so that the blow molding material passes through the cold air machine 5, the circular hole on the support plate 2, the through hole on the top plate 7 and the herringbone frame 8, and the extrusion blower 3 blows the blow molding material into a cylindrical shape. Start the cold air machine 5, and the cold air machine 5 blows out cold air inwards to cool the cylindrical blow molding material. Finally, the blow molding material is extruded from the top of the herringbone frame 8 for the next processing. The method of using the cold air machine 5 to cool the blow molding material can improve the cooling efficiency of the blow molding material.

[0020] It also includes a cylinder 6, two cylinders 6 are fixedly arranged between the support plate 2 and the fixed plate 4, and the piston rods of the cylinders 6 are fixedly connected to the top of the fixed plate 4. After the air cooler 5 is started, the cylinder 6 is started again, so that the piston rod of the cylinder 6 moves up and down to drive the fixed plate 4 to move up and down, which can expand the cooling range of the air cooler 5 and improve the cooling efficiency of the air cooler 5 on the blow molding material.

[0021] It also includes a hollow tube 10, a condenser 11, a water-cooling box 12, a first water pump 13, a second water pump 14, an extension plate 20 and a connecting pipe 21. The rear side of the support plate 2 is fixedly connected to the extension plate 20, the top of the extension plate 20 is fixedly connected to the water-cooling box 12, the water-cooling box 12 is filled with condensate, the bottom of the water-cooling box 12 is fixedly connected to the first water pump 13, the left side of the water-cooling box 12 is fixedly connected to the second water pump 14, the second water pump 14 passes through the extension plate 20, a plurality of hollow tubes 10 are fixedly provided on the left and right sides of the herringbone frame 8, the front and rear sides of adjacent hollow tubes 10 are fixedly connected to the connecting pipes 21, the condenser 11 is connected between the first water pump 13 and the second water pump 14, and the hollow tube 10 and the connecting pipe 21 are both connected to the condenser 11.

[0022] After starting the extrusion blower 3, the air cooler 5 and the cylinder 6, start the first water pump 13 and the second water pump 14. The second water pump 14 draws the condensate in the water cooling box 12 into the condenser tube 11. The condensate in the condenser tube 11 is transported to the hollow tube 10 through the connecting tube 21. The first water pump 13 draws the condensate in the hollow tube 10 into the water cooling box 12 through the connecting tube 21 and the condenser tube 11, so that the condensate in the water cooling box 12 circulates in the connecting tube 21, the condenser tube 11 and the hollow tube 10. When the blow molding material moves upward to contact the hollow tube 10, the hollow tube 10 can further cool the blow molding material.

The method of using the cold air machine 5 to cool the blow molding material can improve the cooling efficiency.

[0027] After starting the first water pump 13 and the second water pump 14, start the vacuum pump 16. The vacuum pump 16 extracts the air in the spiral empty tube 15 through the ventilation pipe 17 and the air intake pipe 18 and circulates the air for cooling. The outer wall of the spiral empty tube 15 contacts the condensate in the water cooling box 12, which can cool the condensate in the water cooling box 12, thereby cooling the hollow tube 10.

[0028] The reinforcing plate 9 can reinforce the herringbone frame 8 to prevent the herringbone frame 8 from shifting and causing the blow molding material to be unable to be extruded normally.

[0029] The cover 19 can prevent workshop impurities from entering the water cooling box 12 and contaminating the condensate, and can also prevent the condensate from spilling out of the water cooling box 12 .
