Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

With reference to fig. 1-2, a sterilization device for preforms 4 of the type described above comprises a sterilization unit, an irradiation unit and a heating unit through which the preforms 4 are conveyed in sequence. In this embodiment, the sterilisation unit comprises a first thumbwheel assembly 5, the illumination unit comprises a second thumbwheel assembly 6 and the heating unit comprises a third thumbwheel assembly 7. A plant for sterilizing preforms 4 of the type described above also comprises a feeding assembly 8 for feeding the preforms 4 into the first wheel assembly 5, a first transition wheel 9 interposed between the first wheel assembly 5 and the second wheel assembly 6, and a second transition wheel 10 interposed between the second wheel assembly 6 and the third wheel assembly 7. The preform 4 is used to prepare a sterile bottle.

Referring to fig. 1-2, a blank feeding assembly 8, a first thumb wheel assembly 5, a first transition thumb wheel 9, a second thumb wheel assembly 6, a second transition thumb wheel 10 and a third thumb wheel assembly 7 are respectively arranged on the frame in a manner of rotating around the axis direction of the blank feeding assembly; the preforms 4 are sequentially conveyed through the six in the rotation process of the six.

The first thumb wheel assembly 5 is provided with nozzles 1, and a plurality of nozzles 1 are uniformly arranged on the first thumb wheel assembly 5 at intervals along the circumferential direction and are used for spraying disinfectant steam into the preforms 4 fed into the first thumb wheel assembly 5 in a one-to-one correspondence manner. In this embodiment, the disinfecting solution is a solution containing hydrogen peroxide.

The second wheel assembly 6 is provided with ultraviolet lamps 2, and a plurality of ultraviolet lamps 2 are uniformly arranged on the second wheel assembly 6 at intervals along the circumferential direction and are used for irradiating the preforms 4 fed into the second wheel assembly 6 in a one-to-one correspondence manner so as to activate the disinfectant therein and sterilize the corresponding preforms 4.

The third wheel assembly 7 is provided with a heating oven for radiantly heating the preforms 4 to evaporate the sterilizing liquid remaining therein.

The sterilizing liquid is irradiated and activated by the ultraviolet lamp 2 to sterilize the preform 4, and then the preform 4 is heated by the heating furnace to evaporate the residual sterilizing liquid, so that the sterilizing liquid basically has no residue, and the problem that the bottle forming quality is not fully influenced by insufficient vaporization of the sterilizing liquid is avoided.

Referring to fig. 3, the injection direction of the nozzle 1 is vertically downward and parallel to the axial center line direction of the preform 4. The nozzle 1 is intended to inject sterilizing fluid vapour along one inner wall of the preform 4 and along the other inner wall of the preform 4. The blow-off is defined here as the fact that the sterilizing liquid vapour, after having returned upwards in a substantially U-shaped path, can rise again at least to the level of the top of the preform 4. By means of this spraying, the sterilizing liquid vapour sprayed out of the nozzle 1 is able to cover the entire inner surface of the preform 4.

Referring to fig. 4, the direction of the spray from the nozzle 1 is at an angle to the direction of the axis of the preform 4. The nozzle 1 is intended to spray the sterilizing fluid vapour uniformly onto the inner surface of the preform 4 in a spiral downward direction. By this spraying, the sterilizing liquid sprayed from the nozzle 1 spirals down along the inner surface of the preform 4 and can be uniformly adhered to the entire inner surface of the preform 4.

Through the two spraying modes, on the basis of ensuring that the disinfectant can be uniformly attached to the inner surface of the preform 4, the consumption of the disinfectant is reduced, the cost is saved, and the problem that the molding quality of the bottle is not fully influenced due to insufficient gasification caused by accumulation of the disinfectant is also avoided.

The second wheel assembly 6 is provided with a lifting mechanism 11 for driving the ultraviolet lamps 2 to move up and down in a one-to-one correspondence manner so as to extend into the preforms 4 in a one-to-one correspondence manner. Referring to fig. 5, the elevating mechanism 11 is used to extend the ultraviolet lamp 2 into the preform 4 to sufficiently sterilize the inner surface of the preform 4 after a certain period of irradiation.

Referring to fig. 6, the oven comprises an infrared lamp provided on the third wheel assembly 7 for irradiating the preforms 4 to the first temperature. Each preform 4 corresponds to a plurality of infrared lamps arranged at intervals from top to bottom. The first temperature is greater than or equal to the vaporization temperature of the disinfecting liquid. By this arrangement, the sterilizing liquid remaining on the preforms 4 can be sufficiently evaporated, leaving substantially no sterilizing liquid remaining. The first temperature may also be equal to the high-stretch temperature of the preform 4, for enabling the preform 4 to be raised to the blow-moulding temperature before entering the blow-moulding station. Wherein the temperature of the preform 4 in the high elastic state is greater than the evaporation temperature of the sterilizing liquid.

The following specifically explains the working process of this embodiment:

the blank feeding thumb wheel feeds the preform 4 into the first thumb wheel assembly 5, the nozzle 1 sprays the sterilizing fluid vapor into the preform 4 so as to be uniformly adhered to the inner surface of the preform 4;

the preforms 4 in the first dial wheel assembly 5 enter the second dial wheel assembly 6 through the first transition dial wheel 9, the lifting mechanism 11 drives the ultraviolet lamp 2 to descend into the preforms 4, the ultraviolet lamp 2 irradiates in the preforms 4 for a period of time during the autorotation process of the second dial wheel assembly 6, so as to activate the sterilizing liquid therein to sterilize the preforms 4, and then the lifting mechanism 11 drives the ultraviolet lamp 2 to ascend to separate from the preforms 4;

the preforms 4 in the second wheel assembly 6 pass through the second transition wheel 10 into the third wheel assembly 7, where the preforms 4 are irradiated by infrared lamps in a heating oven to a first temperature to evaporate the sterilizing liquid remaining in the preforms 4.
