[0036] See also Figure 1 , Figure 5 As shown, this embodiment provides a container sterilization device, including a frame 1, a turntable 2 rotatably arranged on the frame 1 around its own axis, an electron beam irradiation mechanism 4 arranged on the frame 1 and located outside the circumference of the turntable 2, and a first body 6 arranged on the frame 1 and having a shielding cavity, wherein the turntable 2 is arranged in the first body 6, and the electron beam irradiation mechanism 4 is connected to the first body 6. The electron beam irradiation mechanism 4 includes an electron beam generator 41 and an electron beam irradiation window 42 located on the irradiation path of the electron beam generator 41.
[0037] In this embodiment, the turntable 2 is a star wheel, and the frame 1 is also provided with a feed wheel 7 which can rotate around its own axis and is used to cooperate with the turntable 2 to feed materials, and a discharging wheel 8 which can rotate around its own axis and is used to cooperate with the turntable 2 to discharge materials. The feed wheel 7 and the discharging wheel 8 are both arranged in the first main body 6, and the axis lines of the feed wheel 7, the discharging wheel 8 and the turntable 2 are parallel to each other and are all arranged in the vertical direction.
[0038] See also Figure 2 As shown, it is the junction of the feed wheel 7 and the turntable 2; see Figure 3 As shown, it is the junction of the turntable 2 and the discharge wheel 8.
[0039] The container sterilizing device further comprises a plurality of clamping mechanisms 3 arranged evenly spaced in the circumferential direction on the turntable 2 and used for clamping the containers one by one, see Figure 7-8 As shown, the clamping mechanism 3 includes a connecting member 31 arranged on the turntable 2, a rotating member 32 arranged in the connecting member 31 and rotatable around a direction parallel to the axis of the turntable 2, a gear 33 coaxially arranged on the rotating member 32, and a clamping member 34 arranged on the rotating member 32 and used for clamping the container mouth.
[0040] In this embodiment, the clamping member 34 includes a pair of clamping jaws, which can be opened and closed by rotating around the direction perpendicular to the axis of the turntable 2. The clamping jaws are provided with a torsion spring 341 for providing elastic restoring force to drive them to close. The pair of clamping jaws are used to clamp the container so that it is arranged coaxially with the gear 33. The electron beam emitted by the electron beam irradiation mechanism 4 is perpendicular to the axis of the gear 33, and the axis of the gear 33 is parallel to the axis of the turntable 2. Figure 4 As shown, when the container passes through the electron beam irradiation mechanism 4 and the rotating member 32 drives the container to rotate, the entire outer surface of the container can be evenly irradiated by the electron beam irradiation mechanism 4, thereby ensuring uniform sterilization of the entire container.
[0041] See also Figure 5-6As shown, the container sterilizing device further includes a guide member 5 disposed on the frame 1, the guide member 5 having an outer circumferential surface disposed coaxially with the turntable 2, an arcuate gear ring 51 for meshing with the gear 33 is disposed on the outer circumferential surface of the guide member 5, and the arcuate gear ring 51 is located on the side of the guide member 5 facing the electron beam irradiation mechanism 4. In this embodiment, the arcuate gear ring 51 is entirely located in the positive irradiation area of the electron beam irradiation mechanism 4, that is, the arcuate gear ring 51 is aligned with the electron beam irradiation window 42 along the irradiation direction of the electron beam.
[0042] The gear 33 comprises a cylindrical first body 331, a tooth tip group 332 and a guide post 333 arranged in sequence along the circumferential direction and convexly arranged on the outer peripheral portion of the first body 331, and the guide post 333 is used to abut against the outer circumferential surface of the guide member 5 before and after the gear 33 passes through the arc gear ring 51. The first arc segment where the tooth tip group 332 is located and the second arc segment where the guide post 33 is located form a complete circle.
[0043] See also Figure 2 As shown, it is the junction of the feed wheel 7 and the turntable 2, at which time the gear 33 is attached to the guide member 5 through the guide column 333; see Figure 3 As shown, it is the junction of the turntable 2 and the discharge wheel 8, at which the gear 33 is also attached to the guide member 5 through the guide column 333. Through the setting of the guide column 333, the gear 33 can be attached to the guide member 5 at the same angle before and after passing through the arc gear ring 51, so as to ensure smooth connection with the feed wheel 7 and the discharge wheel 8.
[0044] In this embodiment, the guide member 5 is a guide ring, the outer diameter of which is larger than the outer diameter of the turntable 2. One end of the connecting member 31 is connected to the turntable 2, and the other end of the connecting member 31 extends outward from the guide ring along the radial direction of the turntable 2, so that the gear 33 can mesh with the outer side of the arc-shaped gear ring 51. Figure 2-3 As shown, the gear 33 is disposed on the upper portion of the rotating member 32 , and the gear 33 is higher than the connecting member 31 and is at the same height as the guide ring.
[0045] See also Figure 6 As shown, the side of the guide column 333 used to abut the outer circumferential surface of the guide ring is a concave arc surface 3331, and the radius of the arc surface 3331 is the same as the radius of the outer circumferential surface of the guide ring. Through this arrangement, during the container conveying process (before reaching the arc gear ring 51 and after passing the arc gear ring 51), the arc surface 3331 of the guide column 333 can always be in close contact with the outer circumferential surface of the guide ring. This structure has the following advantages:
[0046] First, the guide column 333 can play a guiding role, ensuring the stable transmission of the container before and after the tooth tip group 332 and the arc-shaped gear ring 51 are engaged;
[0047] Secondly, the guide column 333 can play a positioning role, so that the tooth tip group 332 can always stably mesh with the arc gear ring 51 at a set angle, ensuring that the container is accurately positioned in the electron beam irradiation area, so as to further ensure the all-round sterilization effect on the container.
[0048] In this embodiment, the guide ring is a closed circular ring.
[0049] In another embodiment, the guide ring is an arc whose two ends pass through the feed point (i.e., the intersection of the feed wheel 7 and the turntable 2) and the discharge point (i.e., the intersection of the turntable 2 and the discharge wheel 8). Obviously, the arc passes through the irradiation area of the electron beam irradiation mechanism 4.
[0050] In this embodiment, the arc length of the tooth tip group 332 is the same as the arc length of the arc-shaped gear ring 51, so as to ensure that the container can stably rotate through a set angle.
[0051] The working process of this embodiment is described in detail below:
[0052] The feeding wheel 7 transfers the container to the turntable 2, so that the container is clamped by the clamping member 34 on the turntable 2, completing the feeding handover;
[0053] During the process of the container rotating and conveying on the turntable 2, the guide column 333 cooperates with the guide member 5 to ensure its stable conveyance until it passes through the arc gear ring 51;
[0054] Under the meshing action of the arc-shaped gear ring 51 and the tooth tip group 332, the container rotates around its own axis during the rotational conveying process, and at the same time receives the electron beam irradiation from the electron beam irradiation mechanism 4. After a fixed number of meshing teeth, the tooth tip group 332 is disengaged from the arc-shaped gear ring 51, and then continues to cooperate with the guide column 333 and the guide member 5 to ensure the stable conveying of the container.
[0055] The turntable 2 transfers the container to the discharge wheel 8 to complete the discharge handover.
[0056] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
