[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0030] like Figures 1 to 10 As shown, a top-illuminated X-ray machine includes: a frame 1, a conveyor belt assembly 2 passing through the frame 1, the conveyor belt assembly 2 including two support plates 21 spaced apart from each other, a first rotating roller 22 disposed on one side of the upper end of the two support plates 21, a second rotating roller assembly 23 disposed on the other side of the upper end of the two support plates 21, a third rotating roller 24 disposed on one side of the lower end of the two support plates 21, a first adjusting assembly 25 disposed between the third rotating roller 24 and the two support plates 21, capable of adjusting the positions of the two rollers 24, and a third adjusting assembly 25 disposed on the other side of the lower end of the two support plates 21. Four drive rollers 26, two of the support plates 21 are provided with mounting positions 211, the fourth drive roller 26 is provided with a mounting part 261 that can be snapped into the fourth drive roller 26, the fourth drive roller 26 is detachably connected to the two support plates 21 through the mounting part 261, a conveyor belt 27 is provided between the fourth drive roller 26, the third rotating roller 24, the second rotating roller assembly 23 and the first rotating roller 22, and when each of the rotating rollers is installed in place, the first adjusting assembly 25 is adjusted so that the third rotating roller 24 moves relative to the two support plates 21, thereby making the conveyor belt 27 taut.

[0031] In use, the first rotating roller 22, the second rotating roller assembly 23, the third rotating roller 24, and the fourth transmission roller 26 are installed on their respective support plates 21. The fourth transmission roller 26 is installed by its mounting part 261 snapping into the mounting position 211 of the support plate 21. Then, the conveyor belt 27 is fitted onto the first rotating roller 22, the second rotating roller assembly 23, the third rotating roller 24, and the fourth transmission roller 26. By operating the first adjusting component 25, the third rotating roller 24 is driven to move relative to the two support plates 21 in a direction away from the fourth transmission roller 26, and the conveyor belt 27 is gradually tightened until it reaches the required tension. When it is necessary to disassemble the conveyor belt 27 and each rotating roller for cleaning, the first adjusting component 25 is operated, and the conveyor belt 27 is released, allowing the conveyor belt 27 and each rotating roller to be disassembled. Installation and disassembly are both very convenient.

[0032] The mounting part 261 is a protruding post that protrudes relative to the fourth transmission roller 26. The mounting position 211 includes a sliding groove 2111 that allows the protruding post to slide laterally and a clearance groove 2112 that communicates with the sliding groove 2111 and is vertical. The sliding groove 2111 is provided with a stop surface 2113 that can abut against the protruding post. When the protruding post slides relative to the sliding groove 2111 and disengages from the clearance groove 2112, the protruding post can abut against the stop surface 2113 to prevent the protruding post from disengaging from the sliding groove 2111.

[0033] By designing the mounting part 261 as a protruding post and providing a mounting position 211 containing a sliding groove 2111 and a clearance groove 2112 on the support plate 21, the installation and disassembly of the fourth drive roller 26 are extremely simple. During installation, simply align the protruding post with the clearance groove 2112 and insert it vertically. The protruding post moves from the clearance groove 2112 into the sliding groove 2111, and then slides laterally along the sliding groove 2111 to its final position. Disassembly is performed in the reverse direction. The stop surface 2113 provided in the sliding groove 2111 forms a limiting position with the protruding post. When the protruding post slides along the sliding groove 2111 until it leaves the area of ​​the clearance groove 2112 and abuts against the stop surface 2113, the stop surface 2113 prevents the protruding post from disengaging from the sliding groove 2111, ensuring the axial and circumferential positioning stability of the fourth drive roller 26 during operation.

[0034] The sliding groove 2111 is further provided with a first limiting surface 2114 and a second limiting surface 2115. When the protrusion abuts against the first limiting surface 2114, the protrusion corresponds to the stop surface 2113. When the protrusion slides outward and abuts against the second limiting surface 2115, the protrusion aligns with the clearance groove 2112. The first limiting surface 2114 and the second limiting surface 2115 added to the sliding groove 2111 provide a clear positioning reference for the sliding trajectory of the protrusion. When the protrusion abuts against the first limiting surface 2114, its position corresponds exactly to the stop surface 2113, and the roller is in a locked state. When the protrusion abuts against the second limiting surface 2115, it is precisely aligned with the clearance groove 2112, and the fourth transmission roller 26 is in a detachable state.

[0035] The first adjustment component 25 includes connecting grooves 251 disposed on the two support plates 21, and a rotating shaft 252 extending outwardly on the third rotating roller 24. The first adjustment component 25 also includes support blocks 253 disposed on each support plate 21, each support block 253 having a through hole 2531. A collar 254 is fitted onto the rotating shaft 252, and an extension post 255 passing through the through hole 2531 is disposed on the collar 254. A locking element 256 is disposed on the extension post 255 that can be connected to it. The through hole 2531 on the support block 253 and the extension post 255 of the collar 254 cooperate to ensure that the rotating shaft 252 of the third rotating roller 24 always moves along a preset straight path during adjustment. During adjustment, simply loosen or tighten the locking element 256, slide the extension post 255 to move the third rotating roller 24 to the target position, and then re-lock it. The support plate 21 is also provided with a guide slope 212 that can be connected to the top surface of the connecting groove 251. The guide slope 212 is used to guide the third rotating roller 24 to slide into the connecting groove 251.

[0036] The second rotating roller assembly 23 includes a connecting frame 41 connected to the two support plates 21. Each connecting frame 41 is detachably connected to each support plate 21. The second rotating roller 232 is connected between the two connecting frames 41. A second adjusting assembly is provided between the second rotating roller 232 and the connecting frame 41.

The extension 2321 is fitted with a sleeve portion 235. The sleeve portion 235 is provided with a connecting rod 236 that can pass through the sliding hole 2341. The connecting rod 236 is provided with a locking member 237 that can be connected to it. The detachable connection design between the connecting frame 41 and the support plate 21 allows the second rotating roller assembly 23 to be quickly assembled and disassembled as an independent module. Simultaneously, when adjustment of the second rotating roller 232 is required, tightening or loosening the locking member 237 allows the connecting rod 236 to move away from or towards the first rotating roller 22, thus adjusting the tension of the conveyor belt 27 relative to the four rollers. The second adjustment assembly cooperates with the first adjustment assembly 25 to adjust the tension of the conveyor belt 27 relative to the four rollers.

[0037] One of the two support plates 21 is provided with a mounting hole 214 through which the mounting rod 11 on the frame 1 can pass. Each of the support plates 21 is also provided with a top plate 215 that can support and abut against the mounting rod 11. The mounting rod 11 passes through the mounting hole 214, and the entire conveyor belt assembly 2 is supported and fixed on the frame 1 by the top plate 215.

[0038] A plurality of connecting plates 216 are provided between the two support plates 21 to support them, and a top support plate 217 is provided between the plurality of connecting plates 216 to support the conveyor belt. The top support plate 217 is provided with a first clearance hole 2171. The connecting plates 216 provide lateral support for the two support plates 21, while the continuous planar support of the top support plate 217 prevents the conveyor belt 27 from localized sagging deformation when conveying items.
