AI Technical Summary
The gear set structure of the existing paper roll device cannot be adjusted according to the weight of the consumables, resulting in mismatched power output when dealing with consumables of different weights, which affects the lifespan of the equipment and the quality of the consumables.
A paper roller with mechanically adjustable speed was designed. By adjusting the lever, the meshing of the output gear with linkage gears of different numbers of teeth is controlled, so as to realize flexible adjustment of the transmission ratio. Combined with the damper, stability is provided to ensure the stability of gear meshing.
It enables flexible matching of transmission ratio according to the weight of consumables, improves the adaptability and operational stability of the equipment, avoids gear shift due to vibration, broadens the applicable scenarios, and ensures the consistency of consumable winding and the reliability of the equipment.
