Aiming at the problem of bottle recycling counting, an intelligent and environmentally friendly device for bottle recycling is designed. This device counts through the sensor. During the process of placing the bottle, the vibration of the flip plate structure will occur, which will affect the accuracy of the bottle count. In order to reduce the vibration of the flip plate and improve the accuracy of counting, spring and damper were added into the counting device to establish the vibration mechanics model of the device. Then, MATLAB was used to carry out simulation analysis on the model to select and optimize the spring elastic coefficient k value and damping coefficient c value of the damper. Through the physical model test, the selected elastic coefficient k and damping coefficient c were further verified to meet the expectations. The test results show that the k and c values selected by MATLAB simulation analysis can achieve the ideal damping effect. The method provides reference value for the count of bottle recovery in environmental protection industry.
