Problems solved by technology
[0004] In the traditional production process, after blowing the bottle, let the PET plastic bottle that has just been heated and blown be cooled naturally, because the natural cooling time is longer and the degree of crystallization is larger, it is easy to cause the cooled PET bottle to have different crystallization distribution due to different thicknesses. Particles, dents or even cracks appear

Embodiment Construction
[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0027] Such as Figure 1-6 As shown, a plastic bottle bottom water cooling device includes a frame 200, a water tank 300, a water pump 400 and a water spray structure 100;
[0028] The top of the frame 200 is provided with a workbench; the water spray structure 100 is located above the workbench; the water spray end of the water spray structure 100 is vertical to the workbench upwards, and its water inlet 1211 is connected to the workbench. The water outlet of the water pump 400 is connected; the water inlet of the water pump 400 communicates with the water storage chamber of the water tank 300; power.
[0029] The water spray structure 100 is an atomizing nozzle, including a top cover 110 and a nozzle body 120; the nozzle body 120 is provided with a liquid passage 121, an air passage 122, an annu...

The present invention relates to the field of blow molding, in particular to a plastic bottle bottom water cooling device, which includes a frame, a water tank, a water pump and a water spray structure; the water inlet of the water pump communicates with the water storage cavity of the water tank; The water pressure provided by the water pump provides power for the water flow to break up and spray out at the water spray structure. According to the above content, the present invention proposes a water cooling device at the bottom of a plastic bottle, the water pump provided with it will extract the water in the water tank, and the water will be sprayed out from the nozzle provided by the water spray structure, so that the spray water The discharged water contacts the bottom of the plastic bottle, so as to achieve the effect of rapidly cooling the bottom of the plastic bottle. More preferably, the water spray structure is an atomizing nozzle, so that the water sprayed by the water spray structure is in the form of water mist , so that the cooling effect of the plastic bottle bottom water cooling device on the bottom of the plastic bottle is better.
Description
technical field [0001] The invention relates to the field of blow molding, in particular to a plastic bottle bottom water cooling device. Background technique [0002] Most of the common carbonated beverages, drinking water, fruit juice and tea beverages in life are packaged in PET plastic bottles, and PET plastic bottles are also widely used in many fields such as food, chemical, and pharmaceutical packaging. [0003] PET material is an amorphous material at room temperature, and the molecular arrangement is disordered, and the items are uniform. The molding process of plastic bottles is to heat the preform above 110°C, and then use a stretch rod to blow it up (commonly known as bottle blowing) to form a plastic bottle of the required shape and size in the mold. PET material will crystallize when heated above 100°C, and the bottom part of the plastic bottle is the thickest part of the crystal, which will produce anisotropic characteristics, and the stress in different dire...
