For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figures 1 to 3 As shown, the tension adjustment component for the belt conveyor of this embodiment includes a frame 1, a conveyor belt 2 and a motor 3. The conveyor belt 2 is installed on the frame 1, and the conveyor belt 2 is driven by the motor 3. A mounting frame 4 is installed below the frame 1 and inside the conveyor belt 2. Mounting components are installed at both ends of the mounting frame 4. The mounting components are used to install the mounting frame 4 on the frame 1. A screw rod 6 is installed through a screw hole on the upper end of the mounting frame 4, and an adjusting head 7 is installed on the upper end of the screw 6. A movable plate 8 is rotatably connected to the lower end of the screw 6. A movable frame 9 is movably installed at the lower end of the movable plate 8. A tensioning wheel 10 is rotatably connected to the movable frame 9. The screw rod 6 is driven to rotate by rotating the adjusting head 7, and the screw 6 drives the movable plate 8 to move downward. The movable plate 8 drives the tensioning wheel 10 on the movable frame 9 to extend the belt downward, thereby realizing the tension adjustment of the belt.

[0022] Specifically, the installation assembly includes a fixed rod 501, a movable ring 502, a fixed plate 503, a fixed ring 504 and a locking bolt 505. Fixed rods 501 are installed at both ends of the installation frame 4. The movable ring 502 is installed in a sleeve-type manner on the surface of the fixed rod 501. The fixed plate 503 is installed on the surface of the movable ring 502. The fixed plate 503 is installed on the surface of the fixed rod 501 on the side of the fixed plate 503 close to the installation frame 4. The locking bolt 505 is installed on the surface of the fixed ring 504 through a screw hole. One end of the locking bolt 505 extends to the surface of the fixed rod 501. The movable ring 502 is driven to slide on the surface of the fixed rod 501 by moving the fixed plate 503, so that the two fixed plates 503 are in contact with the inside of the frame 1, and the fixed plate 504 is used to limit the fixed plate 503 so that the fixed plate 503 is located between the frame 1 and the fixed ring 504, which is convenient for installing the installation frame 4 on various types of belt conveyors and has certain applicability.

[0023] Furthermore, the fixing plate 503 is L-shaped, and the two fixing plates 503 are in contact with the frame body 1 respectively.

[0024] Furthermore, guide rods 11 are installed on the upper ends of the movable plates 8 on both sides of the screw rod 6. The upper ends of the guide rods 11 pass through the mounting frame 4 through through holes. The guide rods 11 guide the movement of the movable plates 8 to prevent the movable plates 8 from rotating when moving. The upper ends of the guide rods 11 are located below the adjusting head 7. When a tool is used to rotate the adjusting head 7, the guide rods 11 will not block the tool.

[0025] Furthermore, moving rods 12 are installed through through holes on both sides of the upper end of the moving plate 8, and the moving frames 9 are jointly installed on the lower ends of the two moving rods 12. Elastic springs 13 are installed on the surfaces of the moving rods 12 between the moving frames 9 and the moving plate 8. When the tensioning wheel 10 below the moving frame 9 contacts the belt, the moving frame 9 compresses the elastic spring 13 to realize the movable installation of the moving frame 9, which is convenient for maintaining a certain pressure when the tensioning wheel 10 contacts the belt.

[0026] Furthermore, a limit plate 14 is installed on the upper end of the moving rod 12 above the moving plate 8 . The setting of the limit plate 14 prevents the moving rod 12 from falling off the moving plate 8 .

[0027] The method of using this embodiment is as follows: when installing the tensioning wheel 10, the moving fixed plate 503 drives the moving ring 502 to slide on the surface of the fixed rod 501, so that the two fixed plates 503 are in contact with the inside of the frame 1, and the fixed ring 504 is used to limit the fixed plate 503 so that the fixed plate 503 is located between the frame 1 and the fixed ring 504, thereby achieving the installation of the mounting frame 4, and then the adjusting head 7 is rotated using a tool, the adjusting head 7 drives the screw 6 to rotate, the screw 6 drives the moving plate 8 to move downward, the moving plate 8 drives the tensioning wheel 10 on the movable frame 9 to move downward, so that the tensioning wheel 10 extends downward to the belt, thereby achieving the adjustment of the belt tension, and effectively improving the adjustment efficiency of the belt tension.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
