An embodiment is substantially as shown in figures 1 to 5 of the accompanying drawings, a splitting mechanism comprising a first splitting assembly 1 and a second splitting assembly 2. The first and second flow dividing assemblies 1 and 2 are rotatably provided and are located on both left and right sides of the transport member 3, respectively. Both the first and second flow dividing assemblies 1, 2 comprise a turning end for turning and a mating end for mating with each other.

The support frames are arranged on two sides of the transport component 3, and the rotating ends of the first flow dividing assembly 1 and the second flow dividing assembly 2 are both arranged on the support frames. The rotating end can be connected in a rotatable manner through a rotating shaft. The first and second flow dividing assemblies 1 and 2 are rotatable about their respective rotational ends.

The first and second flow dividing assemblies 1, 2 are both arranged above a transport member 3, the transport member 3 being used for transporting articles. The transport element 3 may be a conveyor belt 10.

When it is desired to remove an article from the transport element 3, the first and second flow diversion assemblies 1, 2 are then moved such that the mating ends of the first and second flow diversion assemblies 1, 2 are in abutting engagement with each other. After that, when the article contacts the first and second diverting assemblies 1 and 2, the article is blocked by the first and second diverting assemblies 1 and 2, and is deviated from the transporting direction of the transporting member 3 along with the arrangement direction of the first and second diverting assemblies 1 and 2.

It should be noted that, in this embodiment, after the first flow dividing assembly 1 and the second flow dividing assembly 2 are engaged and matched, the total length of the first flow dividing assembly 1 and the second flow dividing assembly 2 must be larger than the width of the transporting member 3, so as to avoid the first flow dividing assembly 1 and the second flow dividing assembly 2 from having a gap when being engaged, such that articles pass through the first flow dividing assembly 1 and the second flow dividing assembly 2.

The first flow dividing assembly 1 and the second flow dividing assembly 2 in this embodiment both include a blocking member 11 and a conveying unit 12, and the blocking member 11 is specifically a mounting frame, and the mounting frame is rectangular. The conveying unit 12 is provided on the mounting frame. The blocking member 11 is adapted to counteract articles located on the transport member 3, and the conveying unit 12 is adapted to move the blocked articles such that the articles are eventually removed from the transport member 3.

The specific working process is as follows: when the article on the transport member 3 is blocked by the blocking member 11, the article is then brought into contact with the conveying unit 12 provided on the blocking member 11. The article is then moved by the conveyor unit 12 so that the conveyor unit removes the article from the transport unit 3 for inspection by security personnel.

It should be noted that, in order to avoid small articles from passing through the gap between the blocking member 11 and the transport member 3, the blocking member 11 is disposed at a height slightly higher than the top of the transport member 3 in this embodiment.

The specific structure of the transport component 3 in the embodiment comprises a conveyor belt and a driving motor, wherein the conveyor belt is arranged on the surface of the blocking component 11 in a surrounding manner. Meanwhile, the two ends of the blocking part 11 are respectively provided with a transmission roller, and the transmission rollers tightly support the two ends of the conveying belt, so that the conveying belt can be driven to move by the transmission rollers. In the embodiment, the transmission roller is in transmission connection with the driving motor, and when the driving motor rotates, the transmission roller rotates along with the driving motor, so that the conveyer belt matched with the transmission roller rolls.

It should be noted that, the sliding groove 7 and the sliding block not only can be mutually matched, but also can realize driving rotation of the split assembly. Meanwhile, the matching between the sliding groove 7 and the sliding block also plays a role in fixing the split assembly, so that the split assembly is prevented from falling down after long-time use.

The moving assembly 6 in the present embodiment mainly includes a first sliding module 61, a second sliding module 62, and a driving motor.

The first sliding module 61 is fixedly connected with the first transmission part 643, the second sliding module 62 is fixedly connected with the second transmission part 644, and the driving motor is in transmission fit with the first sliding module 61 and the second sliding module 62.

When the driving motor rotates, the first and second sliding modules 62 then perform linear motion, and thus the first and second connection members 4 and 5 connected to the first and second sliding modules 61 and 62 perform translational motion. When the first connecting part 4 and the second connecting part 5 move in a translational manner, the first diversion assembly 1 and the first diversion assembly 1 can be driven to rotate through the cooperation of the sliding groove 7 and the sliding block.

The first sliding module 61 and the second sliding module 62 in this embodiment are a sliding rod and a sliding rail, the sliding rail is fixedly arranged on the supporting frame, the sliding rod can perform relative linear motion relative to the sliding rail, and the sliding rod is fixedly connected with the first connecting component 4 and the second connecting component 5 respectively.

Since the gears on the output shaft of the driving motor need to mesh with the gears of the first transmission member 643 and the second transmission member 644, the gears on the output shaft of the driving motor, the gears on the first transmission member 643 and the gears on the second transmission member 644 that cooperate with the driving motor are all helical gears.

The whole transmission process is as follows: when the drive motor rotates, the gear on the output shaft of the drive motor rotates, and the first transmission part 643 and the second transmission part 644 meshed with the gear rotate accordingly. Further, since the first transmission member 643 is connected to the first sliding module 61, the second transmission member 644 is connected to the second sliding module 62, and the first sliding module 61 and the second sliding module 62 can simultaneously perform linear movement (the movement directions of the first sliding module 61 and the second sliding module 62 are opposite). Then, since the first sliding module 61 and the second sliding module 62 are connected with the first splitting assembly 1 and the second splitting assembly 2 through the first connecting member 4 and the second connecting member 5, respectively, the first sliding module 61 and the second sliding module 62 can rotate simultaneously.
