Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0027] Please refer to Figures 1-6 The utility model provides a technical scheme: the tensioning mechanism of transmission belt, including setting up in strip winding machine 1 for to transmission belt 3 is carried out tensioning's tensioning assembly 4:
[0028] Tensioning assembly 4 includes:
[0029] Mounting frame 42, setting up in strip winding machine 1;
[0030] Tensioning piece 44, liftable setting in the inside of mounting frame 42 and with transmission belt 3 is connected, for to transmission belt 3 is carried out tensioning;
[0031] Adjusting part, setting in the lower end of mounting frame 42 and with tensioning piece 44 is connected, for adjusting the position of tensioning piece 44 in mounting frame 42.
[0032] Need to explain is, when working, mounting frame 42 is installed between the two supporting rollers 5 on strip winding machine 1, and the supporting roller 5 is fixed on the mounting shaft 2 on the strip winding machine 1, when the transmission belt 3 is loose or the installation position and the friction between the equipment need to be adjusted, rotate the adjusting part, drive the tensioning piece 44 to move down in the inside of the mounting frame 42, in the process of moving down of the tensioning piece 44, the transmission belt 3 moves with the tensioning piece 44, so that the tensioning piece 44 tightens the transmission belt 3, through the combined design of the mounting frame 42, the tensioning piece 44 and the adjusting part, the quick adjustment of the tensioning degree of the transmission belt 3 is realized, the user only needs to rotate the adjusting part to easily adjust the tensioning degree of the transmission belt 3, the tensioning piece 44 is liftable in the inside of the mounting frame 42, so that the tensioning degree of the transmission belt 3 can be adjusted in a larger range, the needs of different equipment and application scenarios are met, the friction between the transmission belt 3 and the equipment is reduced, the service life of the transmission belt 3 is prolonged, and the risk of equipment failure is reduced.
[0033] In an embodiment, the lower end of the mounting frame 42 is provided with a limiting frame 421, and the interior of the mounting frame 42 is provided with a moving groove 42101 for the movement of the tensioning member 44.
[0034] In this way, referring to Figure 4 and Figure 5 , the presence of the limiting frame 421 can effectively limit the movement of the tensioning member 44 or other components in the vertical direction, ensuring the stable position of the components in the mounting frame 42, preventing them from falling off or shifting, and the moving groove 42101 provides a clear movement path for the tensioning member 44, ensuring that the tensioning member 44 can move along the predetermined trajectory when under stress or operation, thereby improving the stability and reliability of the mechanical system. Through the moving groove 42101, the tensioning member 44 can be adjusted within a certain range to adapt to different tensioning needs or working conditions.
[0035] In an embodiment, the tensioning member 44 includes a moving block 441 slidingly arranged inside the moving groove 42101, a connecting shaft 442 passing through the interior of the moving block 441, and a tensioning roller 443 sleeved on the connecting shaft 442, and the transmission belt 3 is sleeved on the tensioning roller 443.
[0036] In this way, referring to Figure 6 , the moving block 441 can slide within the moving groove 42101, which means that the position of the tensioning roller 443 can be adjusted as needed. By changing the position of the tensioning roller 443, the tension of the transmission belt 3 can be flexibly adjusted to ensure that the transmission belt 3 operates in the best state. The tensioning roller 443 is sleeved on the connecting shaft 442, providing stable support for the transmission belt 3. This design ensures that the transmission belt 3 does not slip due to insufficient tensioning during operation, and also does not overwear due to excessive tensioning.
[0037] In an embodiment, the adjusting member includes a screw rod 45 rotatably arranged at the lower end of the moving block 441 and a rotating block 451 arranged at the lower end of the screw rod 45, the screw rod 45 passes through the limiting frame 421, and the lower end of the limiting frame 421 is provided with a threaded hole 42102 threadedly connected with the screw rod 45.
[0038] In this way, referring to Figure 4 , and Figure 5 , the threaded connection between the screw rod 45 and the threaded hole 42102 provides a precise adjustment mechanism. By rotating the rotating block 451, the extension length of the screw rod 45 can be finely adjusted, thereby precisely controlling the position of the moving block 441 within the moving groove 42101, and further precisely adjusting the tension of the transmission belt 3. The design of the rotating block 451 makes the adjustment operation very simple. Maintenance personnel only need to use tools or manually rotate the rotating block 451 to easily adjust the tension of the transmission belt 3 without the need to disassemble or replace any components, greatly improving work efficiency.
[0039] In one embodiment, an observation port 42103 for observing the installation position of the movable block 441 is provided on one side of the mounting frame 42.
[0040] This design is for reference. Figure 5 The observation port 42103 allows operators to directly observe the specific position of the moving block 441 within the moving groove 42101, thereby quickly determining the tension of the transmission belt 3. This intuitiveness makes the monitoring and adjustment process simpler and faster, improving work efficiency.
[0041] In one embodiment, the strip winding machine 1 is provided with a mounting rod 41 for supporting the mounting frame 42.
[0042] This design is for reference. Figures 3-5 The mounting rod 41 provides a stable support for the mounting frame 42, preventing it from shifting or deforming due to vibration or external force during operation. This stability helps ensure that the tension of the transmission belt 3 remains constant, avoiding damage to the transmission belt 3 or affecting the performance of the equipment due to improper tension.
[0043] In one embodiment, a guide roller 43 for supporting the transmission belt 3 is provided at the upper end of the mounting frame 42.
[0044] This design is for reference. Figure 4 The guide roller 43 provides stable support for the transmission belt 3, which helps to maintain the smooth operation of the transmission belt 3. During the operation of the strip winding machine 1, the transmission belt 3 may be affected by various external forces. The presence of the guide roller 43 can effectively reduce the vibration and offset of the transmission belt 3, and improve the transmission accuracy and stability.
