Fig. 1 shows a box surface sterilization device implementation form according to the present invention, which includes:

two electron beam emitters 1a and 1b which are opposite in space and in staggered arrangement, under the arrangement, the two electron beam generators can be arranged oppositely from top to bottom, a distance is staggered in the transmission direction of the box, one electron beam emitter 2 emits downward, the other electron beam emitter emits upward, the box is transported by a transmission roller, the upper surface or the inner part of the box is irradiated and sterilized by the electron beam emitter emitting downward, after leaving the electron beam emitter emitting downward, the box enters the electron beam emitter emitting upward, and the lower surface of the box is irradiated and sterilized, and the up-and-down arrangement is just an implementation mode, in the specific operation, the electron beam emitters can be arranged on the left side and the right side of the box, the front side and the rear side of the box according to the requirement, or the arrangement with an inclined angle in the transmission direction is realized as long as the relative complete irradiation can be carried out on any two sides of the box, the other faces can be assisted by deflection magnets which are matched with the two sides of the box in the transmission direction;

at least one set of deflection magnets 3 disposed opposite to each other in space on both sides of the case to push the electron beams beyond the width of the case toward each side of the case, in which the electron beams beyond the width of the case require that the length of the band-shaped electron beams emitted from the electron beam emitters must exceed the width of the case, and the electron beam lead-out length can be designed to be longer than the width of the case according to the inclination angle of the side surface of the case, thereby facilitating adjustment of the irradiation dose on the side surface

In the specific operation, the electron beam generator is described in the top-bottom layout, and as shown in fig. 9-12, for the electron beam emitter emitting downward, the excessive electron beam beyond the width of the box continues to fly downward, and passes through the deflecting magnets oppositely disposed at both sides of the box, and the magnetic field of the deflecting magnet pushes the side surface of the box, so as to perform radiation sterilization on the side surface of the box. Deflecting the magnetic field distribution of the magnet so that the electron beam deflection angles at both sides completely cover the side surface of the box; when the box just enters the irradiation area of the downward electron beam emitter, the electron beams which are not shielded by the upper surface of the box are deflected by the deflection magnets on the two sides, and the front surface of the box is subjected to irradiation sterilization treatment. After the front surface of the box passes through the irradiation region, the electron beam deflected by the deflection magnet is irradiated to the side surface of the box to process the side surface. The deflected electron beam starts to irradiate the rear surface of the box when the side surface of the box leaves the irradiation area until the rear surface completely leaves the irradiation area.

Referring to fig. 5 to 8, for the upward electron beam emitter, when the box just enters the irradiation region of the upward electron beam emitter, the electron beam not blocked by the lower surface of the box and the electron beams deflected by the deflection magnets on both sides perform the radiation sterilization process on the front surface of the box. After the front surface of the box passes through the irradiation region, the electron beams which are not blocked by the lower surface of the box and the electron beams which are deflected by the deflection magnets on both sides are irradiated to the side surface of the box to process the side surface. The deflected electron beam and the electron beam not blocked by the lower surface start to irradiate the rear surface of the cartridge until the rear surface completely leaves the irradiation zone. The upper and lower surfaces of the box face the electron beam emitter extraction window, and when passing through one electron beam emitter, the dosage received is larger than the dosage received by the side surface of the box. However, since the upper and lower surfaces can only receive electron beam irradiation from one emitter, and the side surface of the box can receive co-irradiation from two electron beam emitters, which corresponds to two times of irradiation, the total dose of irradiation is substantially equivalent to the dose received by the upper and lower surfaces of the box.

This scheme is through the magnet that deflects with electron beam emitter matched with, has strengthened the irradiation dose of box side surface, has reduced the difference of irradiation dose between six surfaces of box, when guaranteeing that minimum irradiation dose satisfies the requirement of disinfecting, the power of electron beam emitter output can reduce, prolongs electron beam emitter's life.

Referring to fig. 1, a system for applying a cassette surface sterilization apparatus includes:

the sterilizing device is used for uniformly sterilizing six sides of the boxes on the transmission assembly;

a shielding chamber 4 for packaging the sterilization device and ensuring that the irradiation rays do not leak outwards;

a transport assembly 5 for completing the input and output of the box, which is used for inputting the external box into the shielding chamber, ensuring the irradiation dose of the box in the shielding chamber in the transport direction (realized by adjusting the transport speed), and outputting the irradiated box outwards;

wherein, the screened room is provided with double-shielded door group 8 respectively at the input side 6 of box 9, output side 7, and the state of opening of each group double-shielded door is the overall arrangement that staggers, in this kind of structure, through the input side at the screened room, output side (import, export) set up the matched with double-shielded door, its effect lies in can be according to the transmission position of box, open and close the shielded door, in order to guarantee at any moment, import and export all have at least one shielded door to be in the complete closed state, be used for blockking the ray in the work and reveal, and this kind of double-shielded door structure, make the inside maze that need not to turn of screened room, take up an area of little, can directly be applied to on the production line, need not to transport the box to other irradiation mechanism and disinfect, cost is controllable, and the practicality is good, and adaptability is good.

In another example, the spacing between the sets of double-shielded doors in the shielded room is configured to be greater than the length of the cassette. In the specific operation, the distance between the two shielding doors is at least longer than the length of one box, so as to ensure that at any moment, at least one shielding door is in a completely closed state at an inlet and an outlet, and at least one box can be accommodated between the two doors under the state, taking the input side as an example, the outermost shielding door is opened firstly, so that at least one box is positioned between the two shielding doors, the outer shielding door is closed, the inner shielding door is opened, when the box completely leaves the inner shielding door, the inner shielding door is closed, the box is output to the position of an electron beam emitter, irradiation sterilization is carried out, after the sterilization is finished, the box is moved to the output side double shielding door group, the opening and closing modes of the output side double shielding door group are the same as the input side, the position of the box is sensed through a matched sensor in the whole process, and the opening and closing states of the shielding doors are further controlled, automatic control and continuous production are realized.

In another example, the transmission assembly is configured to adopt roller transmission, in this structure, the roller transmission is adopted, continuous production can be realized, the transmission rate can be adjusted in a subsection mode, and meanwhile, the gap between the rollers needs to ensure that the electron beam positioned below passes through the transmission assembly to irradiate the surface of the box.
