[0032] The application scope of electron irradiation technology is getting wider and wider, and it can be used in the fields of industrial material modification, food and medical treatment. In the field of irradiation processing, there are two main mainstream methods: isotope irradiation and electron accelerator irradiation. Among them, the gamma rays emitted by isotopes have strong penetrating power and a wide processing range, but there are safety issues in the use of isotope irradiation processing; electron accelerators are safe and convenient to use, but the electron beams emitted by electron accelerators have weak penetrating power and a small processing range. Therefore, by adding an X-ray conversion target to the electron accelerator, the electron beam generated by the electron accelerator is used to bombard one side of the X-ray conversion target, and X-rays can be generated on the other side of the X-ray conversion target. X-rays have the characteristics of strong penetrating power. By adding an X-ray conversion target to the electron accelerator, the electron accelerator can have two working modes: electron beam irradiation mode and X-ray irradiation mode, so that the application range of the electron accelerator is wider.

[0033] The X-ray conversion target used for the electron irradiation accelerator is fixedly installed directly below the scanning box of the electron irradiation accelerator. In the process of switching between the two irradiation modes of the electron irradiation accelerator, it is usually necessary to manually dismantle or install the X-ray conversion target and its fixed structure, which makes the switching between the two irradiation modes of the electron irradiation accelerator not convenient enough.

[0034] On this basis, an embodiment of the present application provides an X-ray conversion target moving device. When using this device, there is no need to manually disassemble or install the X-ray conversion target, and the two irradiation modes of the electron irradiation accelerator can be freely switched, that is, the X-ray conversion target can be automatically moved from the initial position to directly below the scanning box, or from directly below the scanning box to the initial position.

With this lifting component 31, the support member 32 can be driven to move up and down along the guide rod 313 relative to the base 1 by only adjusting the position of the lifting nut 316 on the lifting screw 315, and the height of the support member 32 can be adjusted, so that the distance between the X-ray conversion target 4 above the support member 32 and the scanning box can be adjusted, thereby making the device suitable for different installation environments, thereby increasing the applicability of the device.

[0042] In a possible implementation of the embodiment of the present application, a threaded hole may be provided on the positioning slider 314, the axis of the threaded hole is perpendicular to the sliding direction of the positioning slider 314, and a locking screw is provided in the threaded hole of the positioning slider 314. After the height of the X-ray conversion target 4 is adjusted by the lifting nut 316, the positioning slider 314 and the guide rod 313 may be locked and fixed by screwing the locking screw, so that the positioning slider 314 can no longer slide freely relative to the guide rod 313, thereby improving the stability of the lifting component 31, and further improving the stability of the X-ray conversion target moving device.

[0043] In a possible implementation of the embodiment of the present application, as Figure 1 and Figure 2 As shown, the moving component 33 includes a sliding component 331 and a driving component 332. The sliding component 331 is arranged between the support member 32 and the moving platform 2. The driving component 332 is arranged between the support member 32 and the moving platform 2. The moving platform 2 moves relative to the supporting member 32 along the sliding component 331 driven by the driving component 332. By setting the driving component 332, the moving platform 2 can be driven to move in the horizontal direction.

The lead screw 3324 is arranged in the bearings. The lead screw 3324 is rotatably connected to the support member 32 through the bearings and the bearing seats. The bearings can support the lead screw 3324 and reduce the friction force, thereby improving the transmission efficiency of the driving member 3321 and extending the service life of the driving member 3321; the lead screw nut 3326 is fixedly connected to the mobile platform 2. Under the drive of the driving member 3321, the lead screw 3324 rotates, so that the lead screw nut 3326 moves along the axial direction of the lead screw 3324, thereby driving the mobile platform 2 to move. Exemplarily, the driving member 3321 can be a servo motor, a stepper motor or a common electric motor.

[0047] In a possible implementation of the embodiment of the present application, the driving member 3321 and the lead screw 3324 may be connected via a coupling 3322. Exemplarily, the driving member 3321 and the lead screw 3324 are connected via a flexible coupling, so that the relative displacement of the axis of the output shaft of the driving member 3321 and the axis of the lead screw 3324 can be compensated.

[0048] In a possible implementation of the embodiment of the present application, see Figure 5 , Figure 5 Schematic diagram of the structure of the mobile platform of the X-ray conversion target moving device provided in the embodiment of the present application.

[0049] In a possible implementation of the embodiment of the present application, see Figure 6 and Figure 7 , Figure 6 This is a front view of the X-ray conversion target moving device provided in an embodiment of the present application. Figure 7 The left side view of the X-ray conversion target moving device provided in the embodiment of the present application. The driving assembly 332 can also be a structure including a cylinder 3327 and a piston rod connecting member 3329. The cylinder 3327 is fixedly arranged on the support member 32, and the piston rod 3328 of the cylinder 3327 is fixedly connected to the piston rod connecting member 3329. Figure 5 The mobile platform 2 shown is fixedly connected to the mobile platform 2 by screws through the driving fixing hole 24. When the cylinder 3327 is actuated, the piston rod 3328 moves axially, thereby driving the mobile platform 2 to move.

[0050] See also Figure 8 , Figure 8 Functional schematic diagram of the X-ray conversion target moving device provided in the embodiment of the present application. The X-ray conversion target moving device provided in the embodiment of the present application is set at a position corresponding to the scanning box 5 of the electron irradiation accelerator. First, the device is fixed on a pre-set table by the base 1; then the distance between the X-ray conversion target 4 and the scanning box 5 is adjusted by the lifting component 31 so that the entire device is located at the desired position. After the device is installed, the user can control the drive component 332 to start and stop the motor and rotate forward and reverse, drive the lead screw 3324 to rotate, or move the piston rod 3328 of the cylinder 3327, thereby driving the mobile platform 2 to move, thereby realizing the positioning and movement of the X-ray conversion target 4.

[0051] For example, when the motor rotates forward, or the piston rod 3328 is pushed out, the X-ray conversion target 4 moves to the bottom of the scanning box 5 and stays there, at which time the irradiation mode of the electron irradiation accelerator is converted from electron beam to X-ray; when the motor rotates reversely, or the piston rod 3328 is retracted, the X-ray conversion target 4 moves from under the scanning box 5 back to the initial position and remains there, at which time the irradiation mode of the electron irradiation accelerator is changed back to the initial electron beam irradiation mode.
