AI Technical Summary
Existing feed batching scales experience large instantaneous impact forces when materials are fed, which traditional springs/rubber pads cannot quickly dissipate, leading to instantaneous overload errors in the weighing sensor and residual vibration transmission. Existing vibration damping bases only disperse vertical vibrations, while horizontal vibrations are easily transmitted to the weighing hopper through the support structure, causing secondary vibrations.
A shock-absorbing and buffering mechanism for a feed batching scale was designed, including a hinged buffering mechanism and a multi-directional buffering mechanism. The elastic buffering structure and the ball joint buffering structure are vertically superimposed and connected, and combined with the damping buffering unit to form a composite multi-level buffering structure. It absorbs vertical impact force and decomposes horizontal vibration. Multi-directional shock reduction is achieved by utilizing the sliding fit of the arc-shaped spring plate, the ball and the hemispherical shell, and the viscoelastic energy dissipation characteristics of the damping column.
It effectively absorbs vertical impact force, significantly reduces horizontal vibration transmission rate, shortens vibration decay time, improves weighing accuracy, and ensures long-term stability and accurate weighing of equipment in high humidity environments.
