AI Technical Summary
In existing automatic screw conveying devices, the elastic components lack elastic adjustment functions, which leads to the attenuation of the elastic coefficient and the increase of vibration amplitude during long-term high-load operation. This affects the orientation and sorting accuracy, increases noise, and may even cause damage to parts.
The moving block system, driven by a lead screw and motor, adjusts the initial compression of the buffer spring to regulate its elasticity, thereby controlling the vibration amplitude and bounce to achieve a buffering effect.
Effective adjustment of the buffer spring force reduces equipment vibration amplitude, improves orientation and sorting accuracy, reduces noise, and extends equipment life.
