Description

Technical Field

[0001] The utility model relates to the technical field of bottle preform cooling, in particular to a bottle preform cooling device. Background Art

[0002] After the PET masterbatch is melted and extruded into a preform in the injection molding machine, there is some residual material at the tail. Before entering the next process, the residual material at the tail of the preform needs to be cut off on a tail cutting machine. When cutting the tail of the preform, the preform is required to be in a hard state after cooling. However, since the newly extruded preform is hot and still in a hot and sticky state, it is difficult to be shortened by the tail cutting machine. Therefore, the newly extruded preform needs to be cooled.

[0003] For example, the utility model patent with announcement number CN216579081U discloses a highly efficient automatic cooling device for preforms, which relates to the field of preform cooling. The device comprises a hood fixedly mounted on a conveyor belt, on which a blowing assembly for blowing air to the preforms on the conveyor belt is arranged, and the hood is opened on both sides along the conveying direction of the conveyor belt. When the utility model is in use, the staff adjusts the height of the fan according to the actual height of the preforms, unscrews the bolts and nuts between the connecting ears and the side plates, flips the support plate of a suitable height downward, rotates the support plate to a horizontal state and abuts against the limit plate, and locks the support plate to the limit plate by the cooperation of the bolts and nuts, and then places the top plate on the support plate in a horizontal state, so that the connecting ears pass through the clamping grooves and are clamped with the clamping grooves, thereby realizing the clamping connection between the top plate and the support plate, realizing the adjustment of the height of the top plate, and then realizing the adjustment of the height of the fan, thereby improving the cooling effect on the preforms.

[0004] However, when the utility model is used, the staff needs to manually adjust the height of the fan according to the actual height of the bottle blank, which is cumbersome to operate, increases the labor intensity of the workers, and has a poor use effect. Utility Model Content
