Detailed Description
A pencil sharpener pencil feeding mechanism comprises a pencil feeding mechanism support 1 and a pencil feeding mechanism base 2 which are arranged in a pencil sharpener shell, wherein the pencil feeding mechanism base 2 is fixed on the pencil feeding mechanism support 1, a pencil sharpening knife set 3 is arranged in the pencil feeding mechanism support 1 in a transmission mode, a pencil feeding mechanism eccentric wheel 4 is arranged in the pencil feeding mechanism base 2 in a transmission mode, the inner end of the pencil feeding mechanism eccentric wheel 4 is in transmission connection with a transmission head 501 outside a secondary transmission gear 5, an inner tooth ring 6 is in transmission connection with a shaft sleeve 502 on the inner side of the secondary transmission gear 5, an inner tooth mesh of the inner tooth ring 6 is connected to a movable knife gear 301 of the pencil sharpening knife set 3, the secondary transmission gear 5 is in mesh connection with a primary transmission fluted disc 7, a driving shaft 701 of the primary transmission fluted disc 7 extends out of the pencil sharpener shell, a pencil feeding mechanism eccentric wheel 4 is in transmission connection with a pencil feeding mechanism outer gear 9, an outer mesh of the pencil feeding mechanism outer gear 9 is connected with a pencil feeding mechanism cam 10, the outer side of the pencil feeding mechanism base 2 is fixedly provided with a pencil feeding mechanism clutch gear seat 11, the outer sides of the pencil feeding mechanism outer gear seat 11 are in transmission connection with a pencil feeding mechanism outer gear shaft 13, and the pencil feeding mechanism outer gear wheel 11 is connected to pencil feeding mechanism outer side shafts 13 through the pencil feeding mechanism outer gear shafts 12, and the pencil feeding mechanism outer gear wheels 13 are in transmission connection with pencil feeding clutch gear shafts 13, and the pencil feeding mechanism outer side gear shafts 13 are in transmission connection between the pencil feeding mechanism clutch gear seat 14.
As shown in fig. 1, 2 and 3, when pencil 100 to be cut is inserted into the gap between the two sides of the pencil feeding mechanism belt pulleys 13, the rocker arm 8 rotates clockwise, the rocker arm 8 drives the primary transmission fluted disc 7 to rotate, the primary transmission fluted disc 7 drives the secondary transmission gear 5 to rotate, the secondary transmission gear 5 simultaneously drives the annular gear 6 to rotate and the pencil feeding mechanism eccentric wheel 4 to rotate, the pencil feeding mechanism eccentric wheel 4 drives the pencil feeding mechanism cam 10 to rotate through the pencil feeding mechanism external gear 9, and the pencil feeding mechanism cam 10 is provided with a cam annular gear which is meshed with the pencil feeding mechanism external gear 9 and is not shown in the drawing. The cam teeth 1001 outside the pencil feeding mechanism cam 10 drive the pencil feeding mechanism pinions 14 on the two sides to rotate relatively, the pencil feeding mechanism pinions 14 drive the pencil feeding mechanism belt pulley 13 to rotate, and the pencil feeding mechanism belt pulley 13 drives the pencil 100 to move into the pencil sharpener set 3 and extend into the pencil sharpener set 3. When the inner gear ring 6 rotates, the pencil sharpener set 3 is driven to rotate by the movable knife gear 301, so that the pencil 100 in the pencil sharpener set 3 is cut. When the pencil 100 is cut, the pinion 14 of the pencil feeding mechanism is forcibly separated from the cam gear 1001 (gear separation) by the reverse force of pencil feeding, and the pencil cutting operation is completed. The pencil 100 is forcibly pulled out vertically by force, the separation speed of the pencil 100 is high, the pencil 100 can be separated by reversely rotating the rocker arm 8, but the separation speed is low, and the separation and the withdrawal of the pencil 100 can be realized.
The outer end of the rocker arm 8 is rotatably connected with a rocker arm handshake 801. The hand-held rocker arm handshake 801 rotates more smoothly.
The middle of the pencil feeding mechanism belt pulley 13 is provided with a clamping groove 1301 for clamping the pencil 100 along the circumferential direction. The pencil 100 is clamped more firmly, which is beneficial to the entry of the pencil 100.
