The National Intellectual Property Administration information shows that Hefei Zhongchen Light Industry Machinery Co., Ltd. has obtained a patent titled "A Rotary Blow Molding Machine with Bottle Bottom Cooling Device," with the authorization announcement number CN 222681732 U, and the application date being April 2024.

The patent abstract shows that the utility model discloses a rotary blow molding machine with a bottle bottom cooling device, which belongs to the technical field of PET bottle production. It includes a transfer star wheel, a heating machine, a mechanical gripper one, a blow molding mold, a mechanical gripper two, and a bottle bottom cooling device. The bottle bottom cooling device includes a compressed air recovery component, a compressed air cooling channel, and a bottle bottom cooling component. During operation, the compressed air recovery component conveys the recovered compressed air to the compressed air cooling channel. The compressed air is cooled through the compressed air cooling channel and then conveyed to the bottle bottom cooling component. The bottle bottom cooling component uses the cooled compressed air to cool the bottom of the bottle, preventing the bottle bottom from shrinking due to untimely cooling, which would affect the performance and quality of the bottle. Moreover, the recycled compressed air is cooled through the compressed air cooling channel to cool the bottle bottom, without increasing additional compressed air consumption or requiring extra refrigeration equipment.
