The tensioning device, as a crucial component of a belt conveyor, is crucial for ensuring its proper operation.

[0003] The prior art patent CN214113898U discloses a belt tensioning device and belt conveyor. The patent conceals the adjustment screw behind the guide rail and shields it on both sides with baffles, preventing it from being exposed. This reduces the risk of rust and damage, reduces the frequency of replacement or repair, lowers costs, and improves production efficiency. The device also offers a low failure rate, easy maintenance, and simple assembly and disassembly. However, in actual use, the following deficiencies remain: In practice, the device cannot adjust the conveyor belt's tension in the horizontal and vertical directions, failing to meet the needs of workers and reducing work efficiency.

[0004] Therefore, a tensioning device for a belt conveyor is needed to solve the problem in the prior art that the conveyor belt cannot be tensioned and adjusted in the transverse and vertical directions. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the embodiments.

[0022] See also Figure 1-4 The present invention provides a belt conveyor tensioning device, comprising a support column 100, one end of which is fixedly connected to a fixing frame 101. A transverse tensioning assembly 200 is provided on one end of the fixing frame 101, and a vertical tensioning assembly 300 is provided in the middle of the fixing frame 101. A first mounting frame 102 is fixedly connected to one side of the fixing frame 101, and a servo motor 103 is fixedly connected to the interior of the first mounting frame 103. The support column 100 ensures the device maintains stability during operation, connects the power supply, and turns on the servo motor 103.

[0023] The transverse tensioning assembly 200 includes a second mounting frame 201 and a bidirectional motor 202. One end surface of the second mounting frame 201 is fixedly connected to a side surface of the fixing frame 101. The second mounting frame 201 is fixedly connected to the bidirectional motor 202. Vertical plates 203 are fixedly connected to both ends of a side surface of the fixing frame 101. The output end of the bidirectional motor 202 is fixedly connected to a rotating rod 204, which is rotatably connected to the vertical plate 203. One end surface of the rotating rod 204 is fixedly connected to a first bevel gear 205. When the bidirectional motor 202 is turned on, the output end of the bidirectional motor 202 drives the rotating rod 204 to rotate, which in turn drives the first bevel gear 205 to rotate.

[0024] The fixing frame 101 has transverse slots 207 formed on both sides thereof. A threaded rod 208 is rotatably connected to one side of the transverse slot 207. The threaded rod 208 extends through one end of the fixing frame 101 and is fixedly connected to a second bevel gear 206. The second bevel gear 206 meshes with the first bevel gear 205. Rotation of the first bevel gear 205 drives the second bevel gear 206, which in turn drives the threaded rod 208.

[0025] The threaded rod 208 is threadedly connected to a moving block 209. One side surface of the moving block 209 is fixedly connected to the first connecting post 104. One side surface of the first connecting post 104 is rotatably connected to the first rotating roller 105. The rotation of the threaded rod 208 causes the moving block 209 to slide within the transverse slot 207. The moving block 209 then moves the first connecting post 104, which in turn drives the first rotating roller 105 to move synchronously.

[0026] A second connecting post 106 is rotatably connected to one side surface of the fixed frame 101. One end surface of the second connecting post 106 is fixedly connected to the output terminal of the servo motor 103. A second rotating roller 107 is fixedly connected to one side surface of the second connecting post 106. A conveyor belt 108 is sleeved on the surfaces of both the second rotating roller 107 and the first rotating roller 105. The output terminal of the servo motor 103 drives the second connecting post 106 to rotate, which in turn drives the second rotating roller 107 to rotate. The second rotating roller 107 drives the conveyor belt 108 to rotate, and the conveyor belt 108 drives the first rotating roller 105 to rotate.

[0027] The vertical tensioning assembly 300 includes an electronic telescopic rod 301, which is fixedly connected to a side surface of the fixing frame 101. Vertical slots 302 are defined on both sides of the fixing frame 101. The output end of the electronic telescopic rod 301 is fixedly connected to a connecting plate 303. The output end of the electronic telescopic rod 301 drives the connecting plate 303 to move within the vertical slot 302, which in turn drives the fixing plate 304 to move.

[0028] A fixing plate 304 is fixedly connected to one side surface of the connecting plate 303, and a vertical tensioning roller 305 is fixedly connected to one side surface of the fixing plate 304. The movement of the fixing plate 304 drives the vertical tensioning roller 305 to move synchronously.

[0029] According to the above working process, it can be known that: the staff first connects the equipment to the power supply, then turns on the switch of the servo motor 103, and drives the second connecting column 106 to rotate through the output end of the servo motor 103, and the second connecting column 106 drives the second rotating roller 107 to drive, and the second rotating roller 107 drives the conveyor belt 108 to rotate, and the conveyor belt 108 drives the first rotating roller 105 to rotate, so that the conveyor is running. When it is necessary to tension the conveyor belt 108, the equipment is stopped, and then the switch of the bidirectional motor 202 is turned on, and the output end of the bidirectional motor 202 drives the rotating rod 204 to rotate, and the rotating rod 204 drives the first bevel gear 205 to rotate, and the first bevel gear 205 drives the second bevel gear 206 to rotate, and the second bevel gear 206 drives the threaded rod 208 to rotate, and the threaded rod 208 is rotated. The rod 208 drives the moving block 209 to move in the horizontal slot 207, the moving block 209 drives the first connecting column 104 to move, and the first connecting column 104 drives the first rotating roller 105 to move, thereby driving the first rotating roller 105 to adjust the horizontal tension of the conveyor belt 108. When it is necessary to adjust the vertical tension of the conveyor belt 108, the output end of the electronic lifting and retracting rod 301 drives the connecting plate 303 to move in the vertical slot 302, the connecting plate 303 drives the fixed plate 304 to move, and the fixed plate 304 drives the vertical tensioning roller 305 to move, thereby adjusting the vertical tension of the conveyor belt 108, meeting the needs of the staff, improving transportation efficiency, avoiding unnecessary waste of resources, and greatly improving the practicality of the equipment.
