Description

Technical Field

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

[0002] Bottle blanks are formed by injection molding, which involves filling raw materials into the gun mold of a mold at a specific temperature and pressure, and then formed under the working conditions of an injection molding machine. After injection molding, they become semi-finished intermediates, and then blow molded into end products. End products include plastic bottles, oil barrels, cosmetic boxes, shampoo plastic bottles, spray bottles and other packaging containers, which are essential products for people's daily lives. Bottle blanks usually have temperature after being molded by an injection molding machine, so a cooling device is needed to cool the bottle blanks.

[0003] However, in the assembly line operation of bottle blank production, the existing device usually requires a cooling device with a larger floor space in order to increase the cooling time of the bottle blank, which cannot meet the requirement of ensuring that the bottle blank has sufficient cooling time while requiring a smaller floor space, and the use effect is poor. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a spiral preform cooling device, which solves the technical problem that the prior cooling device occupies a large area in assembly line operation.

[0006] Preferably, the gas filter assembly includes a filter box, in which a first filter plate and a second filter plate are inserted, one side of the filter box is connected to a connecting pipe, the connecting pipe is connected to the air inlet end of the fan, and the other side of the filter box is provided with an opening.

[0007] Preferably, the filter box is detachably connected with a sealing cover.

[0008] Preferably, a filter screen is fixedly disposed in the opening.

[0009] Beneficial Effects

[0010] The utility model provides a spiral preform cooling device, which has the following beneficial effects: by providing a spiral baffle and allowing the preform to roll or slide on it, the residence time of the preform in the cylinder can be increased, thereby increasing the cooling time of the preform and reducing the footprint of the device; the air can be filtered through the first filter plate and the second filter plate in the filter box to prevent dust in the air from entering the interior of the preform.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] See also Figure 1-2 The utility model provides a technical solution: a spiral preform cooling device, comprising a cylinder 1, a receiving hopper 2 is arranged on the top of the cylinder 1, a central cylinder 3 is fixedly arranged at the center of the cylinder 1, a plurality of blowing holes 4 are arranged on the side wall of the central cylinder 3, a spiral baffle 5 is fixedly arranged between the central cylinder 3 and the cylinder 1, forming a channel for the bottle blank to roll, and cold air is blown out through the blowing holes 4 to cool the bottle blank, a plurality of exhaust holes 6 are arranged on the side wall of the cylinder 1, and the heated gas is discharged out of the cylinder 1 through the exhaust holes 6, a discharging hopper 7 connected to the bottom of the spiral baffle 5 is fixedly arranged at the bottom of the cylinder 1, and the cooled bottle blank will be discharged out of the cylinder 1 through the discharging hopper 7, and a fan 8 is fixedly arranged below the cylinder 1, and the air outlet end of the fan 8 is connected to the central cylinder 3, and the central cylinder 3 is supplied with air through the fan 8, and the air inlet end of the fan 8 is connected with a gas filter component.

[0016] As an embodiment of the utility model, the gas filter assembly includes a filter box 10, in which a first filter plate 11 and a second filter plate 12 are inserted, one side of the filter box 10 is connected to a connecting pipe 9, the connecting pipe 9 is connected to the air inlet end of the fan 8, and the other side of the filter box 10 is provided with an opening, and external air enters the filter box 10 through the opening, and enters the central tube 3 through the connecting pipe 9 after being filtered by the first filter plate 11 and the second filter plate 12.

[0017] As an embodiment of the utility model, a sealing cover 13 is detachably connected to the filter box 10 , and the sealing cover 13 can be opened to clean or replace the first filter plate 11 and the second filter plate 12 .
