Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, specifically a blow molding machine cooling device. Background Technology

[0002] A blow molding machine is a machine that blows bottles into shape. In its simplest terms, it's a machine that softens plastic granules (into liquid) or pre-made bottle preforms into bottles using specific processes. Blow molding machines are convenient, fast, and have a high production capacity. Since their emergence, they have replaced most manual blow molding and are widely used by beverage companies. Most blow molding machines are two-step machines, meaning the plastic raw material must first be made into a preform before blowing. Currently, PET, an environmentally friendly plastic, is commonly used. A blow molding machine, on the other hand, sprays liquid plastic and uses the airflow to blow the plastic body into a mold cavity of a specific shape to create the product. This type of machine is called a blow molding machine. It is also a type of blow molding machine, specifically a hydraulic blow molding machine. Blow molding machines require a cooling system to cool the bottle after the process.

[0003] A prior art patent application (202022011875.5) describes a high-efficiency cooling device for a blow molding machine, comprising a blow molding machine body and a fan intake extending through the upper end of an air-cooled box into its interior. This high-efficiency cooling device for blow molding machines achieves rapid overall cooling through a combination of air and water cooling, increasing the overall cooling speed and effect. However, it cannot perform water cooling on the inside of the bottle, thus affecting the efficiency of bottle cooling in the blow molding machine. Utility Model Content

A blow molding mechanism 16 is provided on the upper side of the base plate 1 via a vertical plate 8. The blow molding mechanism 16 includes a hydraulic cylinder and a lead screw. An air nozzle is provided at the lower end of the hydraulic cylinder. An air pump is provided at one end of the air nozzle via an air supply pipe, which facilitates blow molding processing of multiple blow molding tanks. A fixed mold base 6 is rotatably provided in the middle of the vertical plate 8 via a support plate 2 and a connecting shaft 3. One end of the connecting shaft 3 is connected to a motor 5 via a gear set 4. A movable mold base 7 is provided on one side of the fixed mold base 6. Both the fixed mold base 6 and the movable mold base 7 are equipped with a circulating water cooling tank 12. The circulating water cooling tank 12 is connected to the water storage tank 9 on the base plate 1 through a circulation pipe and a first water pump 11.

Water can be circulated into the circulating water cooling tank 12 through the circulation pipe and the first water pump 11, thereby performing water cooling heat dissipation treatment on the outside of the bottle in the blow molding tank.

[0024] like Figure 1 and Figure 4 As shown, in order to spray water to cool the inside of the bottle, there is also an in-bottle spray water cooling mechanism inside the water storage tank 9. The in-bottle spray water cooling mechanism includes a first water supply pipe 18 installed in the upper part of the water storage tank 9 through a second cylinder 17. A spray head 20 is provided on the upper side of the first water supply pipe 18 through a second water supply pipe 19.
