Description

Technical Field

[0001] The utility model relates to the technical field of pure water production, in particular to a bottle blank feeding machine. Background Art

[0002] Purified water refers to water that has been specially treated or filtered to remove impurities, microorganisms and harmful substances. It is high-purity, colorless, tasteless, odorless and free of impurities. After preparation, purified water is generally bottled and sold.

[0003] The production process of bottles usually involves blow molding the processed preforms. Before blow molding, a feeder is needed to feed the preforms one by one. For example, Chinese patent CN212949125U discloses a preform preheating feeding mechanism, which is provided with a heating component in an insulating box. When the conveyor line drives the preforms through the insulating box, a preheating operation can be performed first, so that the preforms can be preheated to a certain temperature, that is, the preforms have a certain preheating temperature when they are placed in the blowing mold, thereby reducing the preheating time in the blowing mold or even eliminating the need for preheating, thereby improving production efficiency. However, the heating component uses hot air for heating, and the hot air heating effect is not obvious for plastics, and the preform heating effect is not good enough. Therefore, we propose a preform feeder. Utility Model Content
