[0002] Conveyor belts refer to fabric belts mounted on conveyors for transporting objects. They are generally classified as cotton conveyor belts, rubber conveyor belts, and plastic conveyor belts. Later, influenced by technological advancements in machinery manufacturing, motors, chemical and metallurgical industries, conveyor belt conveyors have been continuously improved and have gradually come to complete the internal transport functions of workshops.

[0003] After a period of operation, most existing conveyor belts will become slack due to loss of elasticity or other reasons. Slack conveyor belts will reduce the initial tension, thereby reducing the conveying efficiency. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a conveyor belt tension adjustment mechanism. It solves the problem that after a period of operation, most existing conveyor belts will become loose due to loss of elasticity or other reasons. The loosening of the conveyor belt will reduce the initial tension, thereby reducing the conveying efficiency.

[0005] To achieve the above objectives, this utility model provides a conveyor belt tension adjustment mechanism, including two symmetrically arranged mounting seats. Two mounting plates are symmetrically fixedly connected to the upper ends of the two mounting seats. A conveyor belt is arranged between the two mounting plates. A first tension adjustment component is arranged between the two mounting plates. A second tension adjustment component is arranged at the lower end of the conveyor belt. The tension of the conveyor belt is adjusted from above by the first tension adjustment component, and the tension of the conveyor belt is adjusted from below by the second tension adjustment component.

Each mounting rod is symmetrically fixedly connected to two connecting rods. The corresponding two connecting rods are jointly fixedly connected to an upper top roller.

[0008] The beneficial effects of this utility model are:

[0009] By activating two cylinders, the telescopic ends of the two cylinders drive the lower pressure roller to move downwards via the fixed base. The lower pressure roller presses against the conveyor belt, adjusting the tension of the conveyor belt from the top. By activating two geared motors, the output ends of the geared motors drive the second rotating rod to rotate via the transmission structure. The second rotating rod drives the upper top roller to rotate via the mounting rod and connecting rod. The two upper top rollers rotate upwards relative to each other and press against the conveyor belt, adjusting the tension of the conveyor belt from the bottom, ensuring that the conveyor belt can transport goods normally.

[0010] Preferably, each of the transmission structures includes a first gear and a second gear, each of the first gears being fixedly sleeved on a first rotating rod, and each of the second gears being fixedly sleeved on a second rotating rod, with the first gears and the second gears meshing together.

[0011] Preferably, the two mounting plates are rotatably connected at both ends to a drive roller and a driven roller, and the conveyor belt is sleeved on the drive roller and the driven roller.

The two corresponding connecting rods 907 are jointly fixedly connected to an upper top roller 908.

[0026] In summary, the improvement of this embodiment lies in:

[0027] By activating two cylinders 802, the telescopic ends of the two cylinders 802 drive the lower pressure roller 804 to move downward through the fixed seat 803. The lower pressure roller 804 presses on the conveyor belt 5, and the tension of the conveyor belt 5 is adjusted from the upper end of the conveyor belt 5. By activating two geared motors 901, the output ends of the geared motors 901 drive the second rotating rod 905 to rotate through the transmission structure. The second rotating rod 905 drives the upper top roller 908 to rotate through the mounting rod 906 and the connecting rod 907. The two upper top rollers 908 rotate upward relative to each other and press against the conveyor belt 5. The tension of the conveyor belt 5 is adjusted from the lower end of the conveyor belt 5 to ensure that the conveyor belt 5 can transport goods normally.

[0028] Based on the above, other structures also need to be disclosed in detail, such as:

[0029] Please see Figure 3 Considering that the first rotating rod 902 drives the second rotating rod 905 to rotate, each transmission structure includes a first gear 903 and a second gear 904. Each first gear 903 is fixedly sleeved on the first rotating rod 902, and each second gear 904 is fixedly sleeved on the second rotating rod 905. The first gear 903 and the second gear 904 are meshed together, and the first rotating rod 902 drives the second rotating rod 905 to rotate through the first gear 903 and the second gear 904.

[0030] Please see Figure 1 and Figure 2 The two mounting plates 2 are rotatably connected at both ends to a drive roller 3 and a driven roller 4. The conveyor belt 5 is fitted on the drive roller 3 and the driven roller 4. A conveyor motor 10 is fixedly installed on one of the mounting plates 2. The output end of the conveyor motor 10 is fixedly connected to the drive roller 3. The output end of the conveyor motor 10 drives the drive roller 3 to rotate. The drive roller 3, in conjunction with the driven roller 4, can drive the transmission belt to move.

[0031] Please see Figure 2 In order to install the cylinder 802, a first fixing plate 801 is fixedly connected to both mounting plates 2, and the two cylinders 802 are symmetrically fixedly installed on the first fixing plate 801.

[0032] Please see Figure 3 In order to install the geared motor 901, the first rotating rod 902 and the second rotating rod 905, a rectangular plate 6 is fixedly connected to both mounting bases 1.

[0034] In summary, the working principle of this solution is as follows:

[0035] When adjusting the tension of the conveyor belt 5, two cylinders 802 are activated. The telescopic ends of the two cylinders 802 drive the lower pressure roller 804 downward through the fixed seat 803. The lower pressure roller 804 presses on the conveyor belt 5, and the tension of the conveyor belt 5 is adjusted from the upper end of the conveyor belt 5. Two reduction motors 901 are activated. The left reduction motor 901 rotates clockwise, and the right reduction motor 901 rotates counterclockwise. The output end of the reduction motor 901 drives the first rotating rod 902 to rotate. The first rotating rod 902 drives the second rotating rod 905 to rotate through the first gear 903 and the second gear 904. The second rotating rod 905 drives the upper top roller 908 to rotate through the mounting rod 906 and the connecting rod 907. The two upper top rollers 908 rotate upward relative to each other and press against the conveyor belt 5. The tension of the conveyor belt 5 is adjusted from the lower end of the conveyor belt 5 to ensure that the conveyor belt 5 can transport goods normally.

[0036] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
