面向皮带撕裂视觉检测的输送机皮带减振研究

Research on Vibration Reduction of Conveyor Belt for Visual Detection of Belt Tears

摘要: 针对带式输送机的皮带振动导致基于机器视觉检测的皮带撕裂裂纹图像模糊问题，研制了一套弹簧减振式机械装置。该减振装置采用弹簧 + 螺杆串联 + 滚动轴承结构，既能灵活调节弹簧的预紧力从而有效抑制皮带振动，又能利用滚动摩擦降低皮带磨损和噪声。针对弹簧设计提出了以能量守恒理论为依据，推导出弹簧劲度系数计算公式，并结合机械设计手册查表计算获得弹簧选型与外形参数尺寸，再将这些参数计算值导入有限元仿真分析其减振效果，最后通过带式输送机试验平台试验验证了弹簧设计的正确性和减振装置的有效性。

Abstract: A spring damping mechanical device has been developed to address the issue of blurred images of belt tearing and cracks based on machine vision detection caused by belt vibration in belt convey-ors. The vibration damping device adopts a spring and screw series connection and rolling bearing structure, which can flexibly adjust the pretightening force of the spring to effectively suppress belt vibration and reduce belt wear and noise through rolling friction. Based on the theory of energy conservation, a formula for calculating the spring stiffness coefficient was proposed for spring de-sign. The spring selection and external parameter dimensions were obtained through a table lookup in the mechanical design manual. These parameter calculation values were then imported into finite element simulation to analyze their vibration reduction effect. Finally, the correctness of the spring design and the effectiveness of the vibration reduction device were verified through belt conveyor test platform experiments.
