Description

Technical Field

[0001] This application relates to the field of high-density polyethylene container blow molding technology, and in particular to a high-efficiency cooling device for a large hollow blow-molded high-density polyethylene container. Background Technology

[0002] As is well known, polyethylene is one of the five major synthetic resins. Plastic containers, also known as hollow blow-molded containers, are processed by hollow molding methods. In the production process of plastic containers, appropriate blow molding equipment is required to blow mold them to promote their shaping.

[0003] In related technologies, a search revealed that a utility model patent with publication number CN218256711U discloses a blow molding device for a polyethylene plastic container, comprising: a support frame, an air compressor fixedly connected to the support frame, an exhaust pipe fixedly connected to the air outlet of the air compressor, a three-way valve fixedly connected to the top middle of the support frame, a first cylinder assembly connected to the upper side of the support frame, a blow molding nozzle connected to the lower end of the first cylinder assembly, an electrically controlled slide rail provided on the lower side of the support frame, a movable frame connected to the inner end of the electrically controlled slide rail, a second cylinder assembly provided on the upper side of the movable frame, and a blow molding mold connected to each of the second cylinder assemblies.

[0004] Regarding the aforementioned technologies, the applicant has found that although its existing equipment has solved the problems of low efficiency of the air compressor and inability to facilitate the separation of the blow-molded container from the blow mold, it still has the following defects: when the order volume is large and the production line is running around the clock, the cooling system is inefficient and cannot cool the molding quickly, which will lead to a longer production cycle and a decrease in overall production efficiency. Insufficient cooling may also cause uneven container wall thickness, deformation or surface defects, increasing the defect rate.

[0005] Therefore, we propose a high-efficiency cooling device for large hollow blow-molded containers of high-density polyethylene. Utility Model Content

[0017] A fixing mechanism is provided between the operating plate and the base plate, and is used to fix the blow-molded container.

[0018] As a further embodiment of this utility model: the fixing mechanism includes a multi-stage hydraulic rod, which is detachably installed on the top of the operating panel.

The coolant circulates repeatedly under the combined action of the circulating water pump, circulating water pipe, and cooling water tank, thereby cooling the inside of the blow-molded container. At the same time, by starting the suction pump, the water in the recovery tank is transported to the atomizing nozzle through the hose. The atomizing nozzle sprays water mist onto the outside of the blow-molded container, thereby cooling the outside of the blow-molded container. This improves work efficiency and increases the yield of high-quality products. Attached Figure Description

Under the extension and retraction of the multi-stage hydraulic rod 15, the fixed frame 16 is moved downward until it presses against the blow-molded container 6. Then, the circulating water pump 10 is activated, so that the coolant in the cooling water tank 9 flows to the circulating water pipe 7, thereby achieving the purpose of cooling the inside of the blow-molded container 6. Then, the user activates the suction pump 12, so that the water in the recovery water tank 11 flows to the atomizing nozzle 14 under the action of the hose 13. The water is sprayed onto the outer wall of the blow-molded container 6 by the atomizing nozzle 14. Then, the water flows down to the bottom plate 1 under the action of gravity, and flows into the recovery water tank 11 through the return water trough 23 opened on the bottom plate 1, achieving the purpose of water resource recycling and reuse.
