Description

Technical Field

[0001] The utility model relates to the technical field of transmission belt production, in particular to a tension regulating device for rubber transmission belt production. Background Art

[0002] Tension control is a crucial step in the production of rubber transmission belts. As a key component for transmitting power and materials in mechanical equipment, the quality of rubber transmission belts directly impacts the efficiency and reliability of the mechanical system. To ensure optimal performance during use, such as sufficient strength, durability, and appropriate elasticity, tension must be carefully controlled during production. Maintaining constant tension is particularly crucial during the belt's reprocessing stages, such as coating, vulcanization, and cooling, to prevent belt slack or excessive stretching.

[0003] Its Chinese utility model patent application number 201920621490.5 discloses a reeling system for transmission belt production, which includes an unwinding mechanism and a pressure roller mechanism; the unwinding mechanism includes an unwinding roller frame, an unwinding roller support, a material roller and an unwinding disc brake; the pressure roller mechanism includes a base, the base includes a horizontal bracket and a vertical bracket, a rotating guide roller is installed on the horizontal bracket, and a rotating disc brake is provided on the rotating axis of the rotating guide roller; the device can ensure that the cloth roll does not produce obvious wrinkles during the unwinding process, thereby improving the qualified rate of the finished transmission belt.

[0004] However, this system still has some significant drawbacks. While the coordinated use of the stretching mechanism with the unwinding and pressure roller mechanisms can generally achieve uniform tension distribution, once the stretching mechanism is fixed behind the pressure roller mechanism, its position becomes difficult to adjust. This means that dynamic adjustment of the belt tension during production becomes very inconvenient. Furthermore, if the tension is not set correctly, excessive tension can cause irreversible stretching deformation of the belt during processing, exacerbating wear on production equipment and affecting the stable operation and efficiency of the production line.

[0005] Therefore, developing a new tension adjustment device that can not only accurately control the tension of the transmission belt during the production process but also flexibly adjust the position is of great significance for improving product quality and production efficiency.

By driving the two-way screw rod in the opposite direction, the pressure roller can apply pressure to the transmission belt. By adjusting the height of the pressure roller, the contact surface between the pressure roller and the transmission belt is changed, which makes it easier to adjust the tension of the transmission belt, and has good flexibility.

[0017] 2. When the traction force of the rubber transmission belt increases sharply, the pressure will be transferred to the energy absorbing component.

A bidirectional screw rod 6 is provided for rotation inside the shell 5, and a motor 11 is provided on one side of the shell 5 to drive the bidirectional screw rod 6. The output shaft of the motor 11 is connected to one end of the bidirectional screw rod 6, and a support plate 4 is slidably connected inside the frame 3. Adjustment components 7 for adjusting the height of the support plate 4 are provided on both sides of the bidirectional screw rod 6. A pressure roller 8 is provided at the bottom end of the support plate 4, which can prevent it from tilting, thereby lifting the pressure roller 8, making it convenient to lay the rubber transmission belt between the roller 2 and the pressure roller 8, which can limit the rubber transmission belt. By driving the bidirectional screw rod 6 in the opposite direction, the pressure roller 8 can be made to apply pressure to the transmission belt. By adjusting the height of the pressure roller 8, the tension of the transmission belt can be adjusted. An energy absorption component 9 is provided on the top of the pressure roller 8 to ensure stable tension.

[0026] In this embodiment, preferably, the adjustment component 7 includes a threaded sleeve 701, a support 702 is welded to the bottom of the threaded sleeve 701, the support 702 is hinged to the support arm 703 through a pin, one end of the support arm 703 is hinged to the support 2 704 through a pin, the bottom end of the support 2 704 is welded to the top of the support plate 4, and the bidirectional screw 6 can convert the rotational motion into the linear motion of the threaded sleeve 701. Since the support arm 703 is installed in a hinged manner, the threaded sleeve 701 can change the support arm 703 when it moves. 3, the height of the support plate 4 can be adjusted when the angle of the support arm 703 changes. A slider 705 is welded on the top of the threaded sleeve 701, and a support rail 15 is fixed on the inner wall of the top of the shell 5. The slider 705 is slidably connected to the support rail 15. A slide 12 is provided in the middle of the top of the bracket 1, and the support arm 703 is slidably connected to the slide 12. The extension movement of the support arm 703 can be ensured by the slide 12, and the threaded sleeve 701 can be supported and guided by the slider 705 and the support rail 15.

[0027] In this embodiment, preferably, the energy absorbing component 9 includes a roller seat 901, the pressure roller 8 is rotatably connected to the roller seat 901, and guide columns 902 are fixed on both sides of the top of the roller seat 901. The guide columns 902 are slidably connected to the support plate 4, and the surface of the guide columns 902 is provided with an energy absorbing spring 903. The energy absorbing spring 903 is located between the support plate 4 and the roller seat 901, and a limit plate 904 is fixed on the top of the guide column 902. The pressure roller 8 can be supported by the roller seat 901, and the guide column 902 avoids the rigid connection between the roller seat 901 and the support plate 4, enables it to slide, and can guide it. The support between the support plate 4 and the roller seat 901 can be supported by the energy absorbing spring 903. When the traction force of the traction rubber transmission belt increases sharply, the pressure will be transmitted to the energy absorbing spring 903. The energy absorbing spring 903 can be compressed and can shrink, which can drive the pressure roller 8 to rise, thereby reducing the fluctuation of the tension of the rubber transmission belt and improving the tension stability.

[0028] In this embodiment, preferably, a guide block 13 is fixedly provided in the middle of both sides of the support plate 4, and a guide rail 14 is fixedly provided on the inner wall of both sides of the frame 3.

The reinforcement plate 16 can reinforce the bracket 1 to improve its stability, and the bracket 1 can be fixedly installed through the positioning holes.

[0031] When in use, first fix it through the positioning hole at the bottom of the bracket 1, and then drive the bidirectional screw rod 6 through the motor 11. The bidirectional screw rod 6 can convert the rotational motion into the linear motion of the threaded sleeve 701. Since the support arm 703 is installed in a hinged manner, the threaded sleeve 701 can change the inclination angle of the support arm 703 when it moves. When the angle of the support arm 703 changes, the height of the support plate 4 can be adjusted, and the pressure roller 8 can be lifted. Then, the rubber transmission belt is laid between the supporting roller 2 and the pressure roller 8, and then the bidirectional screw rod 6 is driven in the opposite direction by the motor 11, so that the pressure roller 8 applies pressure to the transmission belt, and its tension can be maintained. The height of the pressure roller 8 is adjusted by the support arm 703, and the contact surface between the pressure roller 8 and the transmission belt is changed, which makes it convenient to adjust the tension of the transmission belt during production.

[0032] During operation, the energy absorbing spring 903 of the energy absorbing assembly 9 can evenly transfer the pressure to the roller seat 901, thereby maintaining the pressure stability between the pressure roller 8 and the rubber transmission belt, and avoiding the phenomenon of uneven force on the rubber transmission belt. When the traction force of the rubber transmission belt increases sharply, the pressure will be transferred to the energy absorbing spring 903. The energy absorbing spring 903 can shrink when compressed, and can drive the pressure roller 8 to rise, avoiding the phenomenon of excessive tension, reducing the fluctuation of the tension of the rubber transmission belt, and improving the tension stability.
