Of course, there may also be a distance between the input end of the first conveying track 1111 and the output end of the second conveying track 1112. In other embodiments of the present invention, the conveying assembly 111 further comprises a third conveying track, and the first conveying track 1111 and the second conveying track 1112 are connected by the third conveying track.
In an embodiment, the conveying structure 110 further includes a reversing assembly 113, the reversing assembly 113 is disposed at an output end of the first conveying track 1111, and the reversing assembly 113 is configured to push the product 200 to be sterilized of the first conveying track 1111 to the second conveying track 1112. The reversing assembly 113 can change the conveying direction of the products to be sterilized 200, so that the front, back, left and right directions of the products to be sterilized 200 on the first conveying track 1111 are different from the front, back, left and right directions of the products to be sterilized 200 on the second conveying track 1112.
Specifically, the reversing assembly 113 is disposed at an output end of the first conveying track 1111, and when the first conveying track 1111 conveys the product 200 to be killed to the output end of the first conveying track 1111, the reversing assembly 113 can push the product 200 to be killed from the first conveying track 1111 to the second conveying track 1112, and the second conveying track 1112 drives the product 200 to be killed to move along the second direction. When the product 200 to be sterilized is on the first conveying track 1111, the product 200 to be sterilized is in the front-back direction along the first direction, and the direction perpendicular to the first direction is in the left-right direction; after the products to be sterilized 200 are pushed to the second conveying track 1112, the products to be sterilized 200 are forward and backward along the second direction on the second conveying track 1112, which is the left and right direction of the products to be sterilized 200 on the original first conveying track 1111, and the direction perpendicular to the second direction of the products to be sterilized 200 is the forward and backward direction of the products to be sterilized 200 on the original first conveying track 1111. It should be noted that the front, rear, left, and right directions of the present invention are based on the movement direction.
Thus, after the product 200 to be sterilized passes through the first irradiation region in the first conveying track 1111, the product 200 to be sterilized is irradiated and sterilized up, down, left and right by the electron beam irradiation structure 120; then, the product 200 to be sterilized is pushed to the second conveying track 1112 through the reversing assembly 113 to change the front, back, left and right directions of the product 200 to be sterilized, so that the product 200 to be sterilized is irradiated and sterilized through the second irradiation region at the left and right sides of the product 200 to be sterilized, namely the front and back directions of the product 200 to be sterilized on the first conveying track 1111, and the front, back, left, right, upper and lower surfaces of the product 200 to be sterilized are sterilized.

The detection member 1132 is provided on the limiting member 1131, and the detection member 1132 can detect whether the product 200 to be sterilized moves in place. The detection member 1132 is matched with the pushing member 1133, and the detection member 1132 controls the pushing member 1133 to move according to the movement condition of the product 200 to be sterilized.

Optionally, the controller 140 is a control chip, a PLC controller 140, an industrial personal computer, or the like.
The movement to the home position here means that the product to be sterilized 200 moves to the end of the first conveying track 1111 so that the detecting member 1132 can detect the position of the product to be sterilized 200. Alternatively, the detecting member 1132 may detect the product to be sterilized 200 in a contact manner, or may detect the product to be sterilized 200 in a non-contact manner. Optionally, the detecting member 1132 is a sensor. Further, the detecting member 1132 is a laser sensor or a contact sensing member. Optionally, the limiting member 1131 is a limiting baffle.

When the second conveying track 1112 drives the products to be sterilized 200 to move out of the conveying track, the controller 140 controls the third irradiator 1221 and the fourth irradiator 1222 to stop working.
In an embodiment, the distance of the irradiation windows 12116 of the third irradiator 1221 and/or the fourth irradiator 1222 relative to the second transport track 1112 is adjustable. That is, the position of the third irradiator 1221 and/or the fourth irradiator 1222 is adjustable.

For example, when only the surface of the product 200 to be sterilized is irradiated for sterilization, the energy range of the electron beam may be selected to be within the range of 120kev to 150kev by each irradiator, or the energy range of the electron beam may be adjusted according to different packaging materials of the product to be sterilized. When it is desired to perform radiation sterilization of the outer package and the interior of the product 200 to be sterilized, the energy range of the electron beam may be adjusted so that the electron beam can pass through the outer package of the product to be sterilized to perform radiation sterilization of the interior product.
