Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in FIG. 1 ~ 4, the automatic pencil feeding mechanism for the pencil sharpener comprises 2 pencil feeding assemblies 7 and a turbine 2 which are reversely arranged and clamped on a mounting frame 1 side by side, wherein each pencil feeding assembly 7 comprises a pencil feeding rubber roller 4, an impeller 3 and a spring 6 which are sequentially sleeved on a rotating shaft 5, and a slipping mechanism is arranged at the connecting position between the impeller 3 and the pencil feeding rubber roller 4.
In this embodiment, a rib position 301 is arranged on one end surface of the impeller 3, a plurality of arc-shaped grooves 401 are arranged on the end surface of the pen feeding rubber roller 4 connected with the impeller 3, and the rib position 301 is clamped in the arc-shaped grooves 401. When the impeller 3 is subjected to an excessive rotating force, the rib 301 slides out of the arc-shaped groove 401, and the slip is generated.
In this embodiment, one end of the rotating shaft 5 is provided with a start-stop protruding ring 501, and the pen feeding rubber roller 4 is abutted against the start-stop protruding ring 501 without the end surface of the arc-shaped groove 401.
