[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 4 In an embodiment of the present invention, a conveyor belt tensioning mechanism includes a bottom plate 8, a base 6 is provided on the top of the bottom plate 8, a first mounting plate 5 is symmetrically fixedly installed on the top of the base 6, and a rotating shaft 12 is passed through the two first mounting plates 5 for rotation connection, a rotating plate 10 is fixedly installed on one end of the rotating shaft 12, one of the rotating plates 10 is threadedly connected with a first bolt 2, and the other ends of the two rotating shafts 12 are fixedly installed with a fixed plate 1, and a squeezing roller 17 is rotatably installed between the two fixed plates 1, and a first rubber pad and a second rubber pad are fixedly installed on the front sides of the fixed plate 1 and the first mounting plate 5, respectively, one end of the second bolt 13 is pressed against the surface of the first rubber pad, and one end of the first bolt 2 is pressed against the surface of the second rubber pad.

[0021] A motor 9 is fixedly mounted on one side of the top of the base plate 8, and a screw rod 4 is fixedly mounted on the output shaft of the motor 9. The screw rod 4 passes through the base 6 and is threadedly connected to the base 6. A slide groove 7 is slidably connected to the top of the base plate 8, and the base 6 is slidably connected to the slide groove 7.

[0022] A guide groove 3 is provided on one of the fixed plates 1, and a slider 15 is slidably connected to the inside of the guide groove 3. A mounting roller 11 is fixedly installed on one end of the slider 15, and a cleaning roller 16 is fixedly installed on the outside of the mounting roller 11. A second mounting plate 14 is fixedly installed on the front side of the slider 15, and a second bolt 13 is threadedly connected to the second mounting plate 14.

[0023] The motor 9 is electrically connected to an external power source via a wire.

[0024] The working principle of this utility model is:

[0025] When the utility model is used, the screw rod 4 is driven by the motor 9 to rotate, and the rotation of the screw rod 4 will drive the base 6 to move along the slide groove 7 under the guidance of the slide groove 7, thereby adjusting the position of the tensioning mechanism according to the situation. Subsequently, the rotating plate 10 is rotated clockwise to drive the fixed plate 1 to rotate. The rotation of the fixed plate 1 will make the pressure roller 17 approach the surface of the conveyor belt. Continuing to rotate clockwise will make the squeezing roller 17 abut against the surface of the conveyor belt more tightly, realizing the adjustment of the tension of the conveyor belt. After the position of the rotating plate 10 is determined, the first bolt 2 is rotated so that one end of the first bolt 2 is pressed against the surface of the first rubber pad to fix the position of the rotating plate 10, thereby realizing the determination of the rotation angle of the fixed plate 1. When it is necessary to clean the surface of the conveyor belt, the second bolt 13 is loosened so that the slider 15 can slide inside the guide groove 3 and slide the slider 15 until the surface of the cleaning roller 16 is in contact with the surface of the conveyor belt. At this time, the idling conveyor belt allows the surface of the conveyor belt and the surface of the cleaning roller 16 to move relative to each other, so that the cleaning roller 16 can clean the surface of the conveyor belt.
