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 drawings and specific implementations.
[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 set above the workbench; the water spray end of the water spray structure 100 is perpendicular to the workbench upward, and its water inlet 1211 is connected to the The water outlet of the water pump 400 is connected; the water inlet of the water pump 400 is in communication with the water storage cavity of the water tank 300; the water pressure provided by the water pump 400 provides for the water flow to break up and spray out at the water spray structure 100 power.
[0029] The water spray structure 100 is an atomizing nozzle, including a top cover 110 and a nozzle...

The invention relates to the field of blow molding, in particular to a plastic bottle bottom water cooling device. The plastic bottle bottom water cooling device comprises a machine frame, a water tank, a water pump and water spraying structures. A water inlet of the water pump is communicated with a water storage cavity of the water tank; water pressure provided by the water pump provides power for scattering and spraying out water flow at the water spraying structures. According to the content, the water pump of the plastic bottle bottom water cooling device pumps out water inside the water tank and sprays water out of spraying ports of the water spraying structures, finally sprayed water makes contact with the bottom of a plastic bottle, and therefore the effect of rapidly cooling the bottom of the plastic bottle is achieved. Preferably, the water spraying structures are atomizing nozzles, so that water sprayed by the water spraying structures is in a mist shape, and the effect for cooling the bottom of the plastic bottle through the plastic bottle bottom water cooling device is better.
Description
Technical field [0001] The invention relates to the field of blow molding, in particular to a bottom water cooling device for plastic bottles. Background technique [0002] Most common carbonated beverages, drinking water, fruit juices and tea beverages in life are packaged in PET plastic bottles, and PET plastic bottles are also widely used in food, chemical, pharmaceutical packaging and many other fields. [0003] PET material is amorphous at room temperature, with disordered molecular arrangement and uniformity. The molding process of plastic bottles is to heat the preform above 110°C, and then use a stretch rod to blow up and expand (commonly known as bottle blowing) to form a plastic bottle of the required shape and size in the mold. The PET material will crystallize when it is heated above 100°C. The bottom part of the plastic bottle is the thickest crystal and will have anisotropic characteristics. The stress in different directions is different, causing hidden dangers. Wh...
