Abstract
Description
Technical Field
[0001] This utility model relates to the field of machinery, and in particular to a multi-layer composite buffer roller part. Background Technology
[0002] A multi-layer composite buffer roller is a functional component designed to meet the needs of mechanical, electronic, and other equipment for shock absorption and energy dissipation during operation. It aims to effectively reduce the impact of equipment vibration and shock, improve equipment stability and service life. This multi-layer composite buffer roller is widely used in automated production lines, precision instruments, automobile manufacturing, and other fields. It not only significantly improves the shock absorption performance of equipment and reduces equipment failure rates, but also provides strong support for the efficient and stable operation of equipment, which is of great significance to promoting the high-quality development of related industries.
[0003] Integrating materials science, structural optimization, and functional integration technologies, this multi-layered composite buffer roller provides efficient and stable buffer protection for equipment operation. Featuring a gradient composite structure design, adaptive buffer adjustment function, anti-aging and corrosion-resistant treatment, standardized interface adaptation, and visualized wear monitoring, this multi-layered composite buffer roller improves buffering efficiency compared to traditional buffer components through optimized structure and materials. It is widely used in machinery manufacturing, logistics transportation, mining and other fields, and is especially suitable for heavy equipment and automated production lines with stringent requirements for buffering performance and reliability.
[0004] Stress transfer and deformation between different material layers exhibit hysteresis. When an external impact force suddenly acts, the molecular chain movement and elastic deformation of the buffer layer material require a certain amount of time to complete energy absorption and dispersion, making it unable to respond quickly to the impact. This results in the impact force not being effectively buffered in a timely manner, and the initial impact peak being too large, which can easily damage the protected components. Consequently, the buffer parts may not be able to quickly return to their initial state, and may be unable to continuously and efficiently perform their buffering function, limiting their application in scenarios with high requirements for response speed. To address these issues, a multi-layer composite buffer roller-type part is proposed. Utility Model Content

[0033] A support ring 6 is fixedly connected to the inner wall of the outer shell 1. A movable column 7 is fixedly connected to the top of the support ring 6. The support ring 6 provides support for the movable column 7. A rack 8 is fixedly connected to the front side of the movable column 7. The linear movement of the rack 8 can drive the movable column 7 and the support ring 6 to move together. A groove 9 is provided on the inner wall of the outer shell 1. The groove 9 provides space for the internal components. A shock-absorbing pad 10 is fixedly connected to the bottom of the support ring 6. The shock-absorbing pad 10 can absorb part of the impact force and reduce the impact force on the support ring 6 and other internal components. A multi-layer buffer assembly is provided at the bottom of the shock-absorbing pad 10.
[0034] Reference Figure 2 and Figure 4 The buffer assembly includes a spring 11, the top end of which is fixedly connected to the bottom end of the shock-absorbing pad 10. A sliding ring 12 is fixedly connected to the bottom end of the spring 11, providing support for the spring 11. A support column 13 is fixedly connected to the bottom end of the sliding ring 12, which transmits the elastic force to the spring 11 and the spring 14. The spring 14 is sleeved on the outside of the support column 13, and the sliding ring 12 provides support for the spring 14.
[0035] Reference Figures 2 to 3 The outer teeth of the rack 8 and the outer teeth of the gear 3 are meshed together. The meshing transmission converts the rotational motion of the motor 2 into the linear motion of the moving column 7. The top of the moving column 7 is fixedly connected to the inner wall of the groove 2 9. The moving column 7 can drive the outer shell 1 to move together. The top of the spring 2 14 is fixedly connected to the bottom of the sliding ring 12. The outer wall of the sliding ring 12 is slidably connected to the inner wall of the groove 2 9.
[0036] The sliding ring 12 slides along the inner wall of the groove 2 9 to adjust the elastic force of the spring 2 14. The bottom end of the spring 2 14 is fixedly connected to the shock-absorbing pad 2 15. The bottom end of the shock-absorbing pad 2 15 is fixedly connected to the inner wall of the groove 2 9. The shock-absorbing pad 2 15 can absorb the remaining vibration of the spring 2 14. The bottom end of the support column 1 13 is fixedly connected to two fixed blocks 16. The fixed blocks 16 provide support for the rotating block 17. The rotating block 17 is rotatably connected to the adjacent side of the two fixed blocks 16. The bottom end of the rotating block 17 is fixedly connected to the active end 18.
[0037] The rotating connection of the rotating block 17 allows the active end 18 to flexibly adjust its angle. The top of the outer shell 1 is fixedly connected to the support column 29, and the top of the support column 29 is rotatably connected to the driven end 20. The support column 29 provides stable support for the driven end 20. The spring 11 is made of phosphor bronze.

The spring 24 is made of chrome vanadium steel. The chrome vanadium steel spring 24 has high strength, high toughness and good fatigue resistance, and can withstand greater impact and pressure.
[0038] Working principle: When motor 2 drives gear 3 to rotate clockwise, gear 3 drives motor 2 to move downward. Motor 2 drives moving column 7 to slide downward. Moving column 7 drives outer shell 1 and support ring 6 to move downward. Support ring 6 compresses spring 11 downward through shock-absorbing pad 10. Outer shell 1 stretches spring 14 downward through shock-absorbing pad 2 15. At this time, the damping operation is completed, which can effectively dissipate a large amount of impact energy and improve the buffering effect.
[0039] When motor 2 drives gear 3 to rotate counterclockwise, gear 3 drives motor 2 to move upward. Motor 2 drives moving column 7 to slide upward. Moving column 7 drives outer shell 1 and support ring 6 to move upward. Support ring 6 stretches spring 11 upward through shock-absorbing pad 10. Outer shell 1 compresses spring 14 upward through shock-absorbing pad 15. At this time, the damping operation is completed, making it more sensitive to small impacts and enabling the buffer to respond quickly.
[0040] Spring 11 is made of phosphor bronze. As the first line of defense in the multi-stage shock absorption structure, it not only maintains stable elastic performance in long-term use due to its good elasticity, wear resistance and corrosion resistance, but also provides initial buffer for Spring 2 14 below. The phosphor bronze material of Spring 11 can effectively absorb the energy generated by small vibrations and slow down the speed of vibration transmission.
[0041] Spring 214 is made of chromium vanadium steel. Its high strength, high toughness and excellent fatigue resistance make it a key barrier against strong impacts. Spring 214, made of chromium vanadium steel, can withstand greater impact and pressure. After the initial shock absorption by spring 11, it further absorbs the remaining vibration energy, complementing spring 11 to form a highly efficient multi-stage shock absorption structure. This comprehensively reduces the impact of vibration on internal components and ensures stable operation of the equipment.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
