For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0025] In one embodiment of the present invention, Figures 1 to 4As shown, a knife-edge belt 21 conveyor is provided, including a base frame 1 and a conveyor belt body 2, the conveyor belt body 2 is installed on the top of the base frame 1, a detection chamber 3 is provided on the top of the base frame 1, a lifting mechanism 31 is provided at the bottom of the detection chamber 3, guide wheels 32 are provided on both sides of the detection chamber 3, and a plurality of thermal imaging sensors 33 are provided in the detection chamber 3.

[0026] Furthermore, a base plate 30 is provided at the bottom of the detection chamber 3. Each of the thermal imaging sensors 33 and each of the guide wheels 32 are mounted on the top of the base plate 30. The output shaft of the lifting mechanism 31 is fixedly mounted to the bottom of the base plate 30. The lifting mechanism 31 includes an installation box 311 and a plurality of lifting cylinders 312 disposed within the installation box 311. The output shafts of the lifting cylinders 312 pass through the top of the base frame 1 and are fixedly mounted to the bottom of the base plate 30. The top of the base frame 1 is also covered with a mounting plate 11. A slot 12 for accommodating the base plate 30 is provided in the middle of the mounting plate 11. Fixing bolts 13 connected to the top of the base frame 1 are provided at the edge of the mounting plate 11. Specifically, when in use, the lifting cylinder 312 is used to push the base plate 30 up and down, thereby driving the guide wheel 32 to tighten or loosen the belt 21 to achieve a tensioning effect; when replacing the belt 21, the lifting cylinder 312 is used to lower the base plate 30, and finally the base plate 30 is stored in the groove body 12. When replacing the belt 21, debris can be prevented from entering the groove body 12 and sticking between the output shaft of the lifting cylinder 312 and the mounting plate 11, thereby ensuring the accuracy of the lifting of the base plate 30 and accurately controlling the tension of the belt 21.

[0027] Furthermore, the conveyor belt body 2 includes a belt 21 and several drive rollers 22 for driving the belt 21 to rotate. Each drive roller 22 is provided with a support rod 23 at both ends, and the bottom of the support rod 23 is fixedly connected to the top of the base frame 1. The conveyor belt body 2 also includes two side guard plates 24. The two side guard plates 24 are provided with several mounting holes 241 for mounting each drive roller 22. Each mounting hole 241 is provided with a bearing. The left and right ends of each drive roller 22 pass through a bearing in a mounting hole 241. The outer side of each mounting hole 241 is provided with a mounting portion 242 for fixing the two ends of the drive roller 22. The conveyor belt body 2 also includes a support plate 25 for supporting the top of the belt 21. The support plate 25 is provided with a support rod 23 on the front and rear sides. The support plate 25 is provided with a tensioning pulley 251 at the bottom, and the tensioning pulley 251 is in rolling engagement with the inner side of the belt 21. Specifically, when the lifting cylinder 312 is used to lift the base plate 30, the two guide wheels 32 press the belt 21, and the bottom part of the belt 21 is lifted up. Finally, the inner side of the bottom part of the belt 21 contacts the tensioning wheel 251, which can reduce the lifting height of the base plate 30 by the lifting cylinder 312 to achieve the effect of tightening the belt 21. Then, a lifting cylinder 312 with a shorter stroke and greater thrust can be used to achieve a better tightening effect of the belt 21.

[0028] Working principle: When in use, the conveyor belt body 2 realizes the function of cargo transportation. After the conveyor belt body 2 completes the cargo transportation operation, the conveyor belt body 2 keeps rotating, and the thermal imaging sensor 33 starts to operate. During the operation of the conveyor belt body 2, the roller 331 rolls with the bottom of the conveyor belt body 2, and the temperature inside the belt 21 will be higher than the temperature outside the belt 21. When cracks appear on the belt 21, the crack is closer to the inside of the belt 21, so the height inside the crack will also be higher than the outside of the belt 21. The temperature distribution of the belt 21 is detected by the thermal imaging sensor 33 to detect whether cracks have occurred on the surface of the belt 21. If cracks occur on the belt 21 and affect the transmission operation, the belt 21 needs to be replaced. During replacement, the detection chamber 3 is lowered by the lifting mechanism 31, so that the two guide wheels 32 are lowered to loosen the belt 21. The old belt 21 is removed and the new belt 21 is installed. Then the lifting mechanism 31 pushes the two guide wheels 32 to compress the belt 21. By setting the detection chamber 3, the tensioning and detection functions of the belt 21 can be realized at the same time, achieving a multifunctional use effect.
