Detailed Description

The technical scheme of the invention is further explained by combining the attached drawings.

Referring to fig. 1-3, the preforms 4 are transported on the transport star 3, above which the electron beam irradiation means 1 are mounted, and on the side of the transport trajectory of the preforms 4, guide magnets 5 are mounted.

The axis of the bottle blank 4 extends along the vertical direction, and the irradiation direction of the electron beam 2 can be parallel to the axis of the bottle blank 4 or form an angle with the axis of the bottle blank 4. The bottle blank 4 has an upward opening, the electron beam 2 irradiates the bottle blank 4 from top to bottom, part of the electron beam 2 enters the bottle blank 4 along the opening of the bottle blank 4 to sterilize the whole inner surface of the bottle blank 4, and part of the electron beam 2 irradiates the outside of the bottle blank 4.

The guide magnet 5 includes a plurality of pairs of magnets, and a gap for allowing the bottle preform 4 to pass through is provided between each pair of magnets. In the present embodiment, the longitudinal extension direction of the magnet is parallel to the axial line direction of the bottle preform 4, the upper end of the magnet is equal to the upper end of the bottle preform 4, and the lower end of the magnet is equal to the lower end of the bottle preform 4. The electron beam 2 emitted to the outside of the preform 4 is deflected by the magnet to irradiate the outer surface of the preform 4, thereby sterilizing the entire outer surface of the preform 4.

Because the surface area of the bottle blank 4 is smaller than that of the bottle after blow molding, the bottle blank 4 is directly irradiated and sterilized by the electron beam 2 and then blown, and the energy consumption of the electron beam 2 can be saved. In the embodiment, the electron beam 2 is the EDS electron beam 2 with low energy, which further saves the energy consumption of the electron beam 2 and reduces the sterilization cost of the preform 4.

(2) irradiating the other part of the electron beams 2 to the outer side of the bottle blank 4, and changing the irradiation direction of the part of the electron beams 2 through a guide magnet 5 arranged at the outer side part of the bottle blank 4 so as to sterilize the whole outer surface of the bottle blank 4; the guide magnet 5 is provided on the side of the movement locus of the preform 4 to deflect the irradiation direction of the other part of the electron beam 2 so as to irradiate the outer surface of the preform 4 passing through the guide magnet 5.

A bottle blowing method comprises the following steps:

(2) irradiating the other part of the electron beams 2 to the outer side of the bottle blank 4, and changing the irradiation direction of the part of the electron beams 2 through a guide magnet 5 arranged at the outer side part of the bottle blank 4 so as to sterilize the whole outer surface of the bottle blank 4; the guide magnet 5 is arranged on the side surface of the motion track of the bottle blank 4 to deflect the irradiation direction of the other part of the electron beam 2 so as to irradiate the outer surface of the bottle blank 4 passing through the guide magnet 5;
