Detailed ways

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other instances, some technical features known in the art are not described in order to avoid confusion with the present invention.

As shown in Figures 1 to 3, an X-ray inspection system, hereinafter referred to as "the system". The system includes a base assembly, the base assembly includes a support column 14 placed on the ground, a bottomless frame 2 fixed on the support column 14 and extending outward from the middle of one side to form a receiving space, passing through the frame 2 The workbench 13 extending to both sides, the cover plate 10 placed on the frame 2, the lead curtain 11 installed above the two sides of the frame 2, the bottom mounting plate of the support column 14 has wheels 7, so The workbench 13 is provided with a conveyor belt 12; the X-ray inspection assembly includes the tape machine 1 installed on the workbench 13, and the photoelectric module 3 externally installed on the tape machine 1 is installed on the frame 2. The X-ray rack 4 below the inner side of the frame 2, a plurality of detector boxes 9 installed above and on one side of the frame 2, the collimator 6 installed on the inner side of the frame 2, and the The electrical installation frame 8 above the inner side of the frame 2, a shielding plate 5 is installed in the side of the frame 2 with the accommodating space, one end of the shielding plate 5 is connected with the X-ray frame 4, and the other end is connected with the X-ray frame 4. The upper ends of the collimators 6 are connected.

The specific working process is as follows: when the object passes through the external photoelectric module 3 on the conveyor belt 12, the photoelectric module 3 converts the electrical signal into an optical signal, and the X-rays pass through the timer 6 to turn the divergent X-rays into parallel beams , the object enters the lead curtain 11 and is sent to the channel, the X-ray scans the object, and the X-ray energy is converted into an electrical signal for recording through the detection box, and the photoelectric module 3 installed on the other side of the lead curtain then transmits the light. The signal is converted into an electrical signal so that a complete image is scanned.

Assuming the channel height H=1m, the distance dimension L2=262mm from the lead curtain 11 to the photoelectric module 3 in the traditional X-ray inspection system, if the tape speed v=0.8m/s, then the distance dimension from the photoelectric module 3 to the center of the main beam L3=vt=o.8m/s×o.8s=0.64m=640mm, L2+L3=902mm<H, at this time, the length of the equipment is L=2H+150=2150mm; if the speed of the tape is v=1m/s, Then the distance between the photoelectric module 3 and the center of the main beam is L3=vt=1m/s×o.8s=0.8m=800mm, L2+L3=1062mm>H, and the length of the device is L=2L2+2L3+150=2 ×262+2×800+150=2274mm; if the speed of the tape is v=1.2m/s, then the distance dimension L3=vt=1.2m/s×o.8s=0.96m=960mm from the photoelectric module 3 to the center of the main beam , L2+L3=1222mm>H, at this time the length of the equipment L=2L2+2L3+150=2×262+2×960+150=2594mm.

In this utility model, if the height of the channel is H=1m, if the tape speed is v=0.8m/s, v=1m/s, v=1.2m/s, it only needs to satisfy L2+L3>H, and the length of the equipment is all For L=2H+150=2150mm, it is only necessary to adjust the size of the distance L1 from the external photoelectric module 3 to the lead curtain 11 to satisfy L1+L2+L3>vt, and the equipment can be used normally.
