[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] See also Figure 1-4 , the utility model provides a technical solution:

[0026] Embodiment 1: A transmission belt tension adjustment mechanism, including a slider fixing seat 1, a driving wheel 9 and a driven wheel 10, a slider baffle 4 is arranged on the top of the slider fixing seat 1, a locking nut 6 is fixedly connected to the top of the slider baffle 4, a tension adjustment screw 5 is threadedly connected to the locking nut 6, and an adjustment block 11 is rotatably connected to one end of the tension adjustment screw 5, and a belt pressing slider 2 is fixedly connected to the front of the adjustment block 11, and a connecting column 18 is fixedly connected to the outer wall of the belt pressing slider 2, and five bearings 3 are arranged on the outer wall of the other end of the connecting column 18, and limiting grooves 13 are provided on both sides of the slider fixing seat 1, and the limiting blocks 12 are fixedly connected to the left and right sides of the adjustment block 11, and the limiting blocks 12 are mutually connected with the limiting grooves 13. Correspondingly, the limit block 12 is slidably connected in the limit groove 13, the belt clamping slider 2 is slidably connected to the outside of the slider fixing seat 1, the driven wheel 10 is connected to the driving wheel 9 by a belt, and the bearing 3 is arranged above the belt. Slide grooves 16 are provided on both sides of the belt clamping slider 2, and a pair of locking screws 7 are provided on the outside of the belt clamping slider 2, and several inner holes 17 are provided on both sides of the outside of the slider fixing seat 1, and the locking screws 7 penetrate the slide grooves 16 and extend into the inner holes 17, and a pair of sockets 14 are provided on the top of both sides of the slider fixing seat 1, and a pair of plug plates 15 are fixedly connected on both sides of the bottom of the slider baffle 4, and the plug plates 15 correspond to the plug plates 14, and the plug plates 15 are slidably connected in the plug holes 14.

[0027] The slider fixing seat 1 is installed on one side between the driven wheel 10 and the driving wheel 9, and is used to adjust the tightness of the transmission belt. When the belt is loose, the adjustment block 11 is driven to adjust downward by turning the tension adjustment screw 5 and fixing the position with the locking nut 6. At the same time, the adjustment block 11 is constrained inside the limit groove 13 of the limit blocks 12 on both sides to ensure that the movement direction of the adjustment block 11 is consistent. When the adjustment block 11 moves downward, the bearing 3 on the belt clamping slider 2 will move downward accordingly, applying pressure to the belt until the appropriate tightness is reached. Once adjusted to the appropriate position, the locking screw 7 will be positioned at the inner hole 17 of the slider fixing seat 1 and tightened through the slide groove 16 to fix the belt clamping slider 2 to prevent vibration during work. At the same time, the slider baffle 4 can be directly pulled out of the socket 14 through the plug plate 15 for replacement and maintenance. This combination makes the adjustment of the tightness of the transmission belt more accurate and quick.

[0028] Embodiment 2: The difference between this embodiment and embodiment 1 is that, a plurality of gaskets 8 are sleeved on the outer wall of the connecting column 18, and the gasket 8 is arranged between the bearings 3 on both sides, a thread groove 21 is opened inside one end of the connecting column 18, and a fixing screw 19 is arranged outside the connecting column 18, and the fixing screw 19 is threadedly connected in the thread groove 21, a plurality of fixing columns 20 are arranged on the inner wall at the rear end of the fixing screw 19, and the fixing columns 20 are rotatably connected to the outside of the connecting column 18.

[0029] The design of the bearing 3 effectively reduces the friction between the transmission belt tension adjustment slider and the belt, thereby extending the service life of the belt. In addition, the gasket 8 provided between the two bearings 3 can effectively separate them to prevent them from rubbing and interfering with each other, further improving the stability of the belt system. When installing the bearing 3, the fixing screw 19 is rotated so that it gradually enters the thread groove 21. The fixing column 20 will gradually approach the bearing 3 and install it on the connecting column 18. When the bearing 3 needs to be replaced, the fixing screw 19 only needs to be rotated in the opposite direction to quickly remove the bearing 3 for replacement. This design makes the installation and replacement of the bearing 3 simple and improves the efficiency of maintenance.

[0030] When working, the transmission belt, as a mechanical transmission device, mainly functions to transmit power from the driving wheel 9 to the driven wheel 10 to realize the operation of the machine. Therefore, the tightness of the belt is very important to the operation of the equipment. When the belt tightness needs to be adjusted, the slider fixing seat 1 is first installed on one side between the driven wheel 10 and the driving wheel 9. When the belt becomes loose, the tension adjustment screw 5 is rotated. When the tension adjustment screw 5 is rotated, it is positioned by the locking nut 6, thereby driving the adjusting block 11 to adjust downward. At the same time, the adjusting block 11 cooperates with the limit blocks 12 on both sides to be limited in the limit groove 13, so as to ensure that the moving direction of the adjusting block 11 is consistent. When the adjusting block 11 moves downward, the bearing 3 on the belt tightening slider 2 will be driven to move downward. The bearing 3 can effectively reduce the friction between the transmission belt tension adjustment slider and the belt, and prolong the service life of the belt. At this time, the bearing 3 will press the belt down until it is of suitable tightness. At this time, after the position is determined, the belt is tightened. By aligning the locking screw 7 with the position of the inner hole 17 on the slider fixing seat 1 and passing it through the slide groove 16, the locking screw 7 is tightened at this time, thereby achieving the function of fixing the belt pressing the slider 2 to prevent the problem of vibration during work. Through the cooperation between them, a more accurate and quick adjustment of the tightness of the transmission belt is achieved. At the same time, a gasket 8 is arranged between the two bearings 3 to separate them to prevent mutual interference and friction. By rotating the fixing screw 19, when the fixing screw 19 gradually enters the thread groove 21, the fixing column 20 will slowly approach the bearing 3, thereby fixing the bearing 3 on the connecting column 18. At the same time, when the bearing 3 is damaged, the fixing screw 19 is rotated in the opposite direction, the bearing 3 can be quickly disassembled and replaced, and the locking screw 7 can be screwed out at the same time, and then the slider baffle 4 is pulled out from the insertion hole 14 through the plug plate 15 by pulling upwards, so that the disassembly and maintenance can be carried out quickly, which greatly improves the work efficiency.
