Example 1:

the working principle of realizing ray shielding by applying each shielding door in a ray shielding device is as follows:

as shown in fig. 1 to 3, taking an example of providing four shielding doors at each radiation shielding device, the workflow of the radiation shielding device at the input side of the irradiation region includes:

when the plate 1 is transported to the entrance of the ray shielding passage 3 by the transport roller 2 and the distance from the first shielding door 4 satisfies a predetermined value, at this time, the preceding plate has completely passed through the second shielding door 5, and the second shielding door 5 has been in a completely closed state, the first shielding door 4 is opened, and the plate 1 enters the inside of the ray shielding passage 3.

When the plate 1 moves to a distance from the second shielding door 5 to satisfy a predetermined value, at this time, the preceding plate has completely passed through the third shielding door 6, and the third shielding door 6 is in a completely closed state, the second shielding door 5 is opened, the plate 1 continues to be transported by the roller 2 deep into the inside of the radiation shielding passage 3, and the distance satisfies the predetermined value, that is, if the plate movement speed is v, the time required for completely closing the shielding door to completely open is t, the predetermined distance D is equal to or greater than v×t, and the same treatment is performed on the distance between other shielding doors satisfying the predetermined value, which will not be described later.

When the sheet 1 moves to a distance from the third shielding door 6 satisfying a predetermined value, at this time, the preceding sheet has completely passed through the fourth shielding door 7, and the fourth shielding door 7 has been in a completely closed state, the third shielding door 6 is opened, and the sheet 1 continues to be transported deep inside the radiation shielding tunnel 3 by the roller 2.

When the sheet 1 moves to a distance from the fourth shielding door 7 to meet a predetermined value, at this time, the tail of the sheet 1 has completely passed through the first shielding door 4 of the radiation shielding channel 3, and when the tail of the sheet 1 leaves the first shielding door 4 to reach a preset distance, the first shielding door 4 is closed, after the first shielding door 4 is in a completely closed state, the fourth shielding door 7 is opened, the sheet 1 continues to be transported by the roller 2 through the fourth shielding door 7 and enters the irradiation area 8, and the preset distance is greater than or equal to 0, that is, when the sheet leaves the shielding door just, the closing of the shielding door can be started, and the closing of other shielding doors is processed as such and will not be described herein.

When the tail part of the plate 1 moves away from the second shielding door 5 to reach a preset distance, the second shielding door 5 is closed, and the preset distance at the moment is the opening and closing process of the shielding door, so that the plate 1 is guaranteed not to collide with the moving plate, and the necessary safety margin is reserved, for example: 20-50 mm more than the critical position of the collision between the plate and the shielding door.

When the tail of the plate 1 moves away from the third shielding door 6 to reach a preset interval, the third shielding door 6 is closed.

When the tail of the plate 1 moves away from the fourth shielding door 7 by a preset distance, the fourth shielding door 7 is closed.

The sheet 1 thus completes a complete pass through the radiation-shielding tunnel 3. In this scheme, the predetermined value is data obtained by integrating the length and the transmission speed of the plate, and the working state of each door is switched by the input value.
