Abstract
The utility model discloses an automatic pencil feeding device of a pencil sharpener. The automatic pencil feeding device of the pencil sharpener is simple in structure and durable. The automatic pencil feeding device of the pencil sharpener is used for solving the technical problem that an existing automatic pencil feeding device of a pencil sharpener is complex in structure, high in noise and prone to damage. The automatic pencil feeding device of the pencil sharpener comprises a fixed frame and a rotary disk arranged on the fixed frame, wherein a sleeving connection hole is formed in the fixed frame, a shaft sleeve is arranged on the rotary disk, and is arranged in the sleeving connection hole in a rotary mode, a transmission shaft is further connected to the fixed frame in a pivot mode, and is driven by rotation of the rotary disk to rotate, even grooves are formed in the rotary disk, and a rubber wheel and a clamping sleeve are installed on the transmission shaft. The automatic pencil feeding device of the pencil sharpener is simple in structure and high in pencil sharpening speed, time and labor are saved, and the automatic pencil feeding device of the pencil sharpener is free of noise and durable.
Description
Technical field
The utility model relates to a kind of penknife, and what be specifically related to a kind of simple in structure, durable a kind of penknife enters pen device automatically.
Background technology
Tradition pencil sharpener automatically enter that pen device comprises fixed mount and the rotating disk which is provided with and by the gear shaft of driven by rotary disc, during work, from gear shaft, drive pencil to move in pencil machine, after pencil sharper has been got well, if user does not feel that now pencil is cut, continue to make dial rotation, gear shaft still can drive pencil inwardly to enter pen, pencil is excessively cut, cause unnecessary waste.
For this reason, someone has designed the patent (China Patent No.: 201120395255.4) of a kind of by name " a kind of penknife automatically enter pen device ", it comprises fixed mount and the rotating disk which is provided with, on fixed mount, offer sleeve joint hole, rotating disk is provided with axle sleeve, and described axle sleeve is located in sleeve joint hole rotationally, is also articulated with gear shaft on fixed mount, gear shaft can rotation under the rotarily driving of rotating disk, on described axle sleeve and between rotating disk and fixed mount, is provided with spring; During use, this device assembles with body, cutting tool group and the swing handle of pencil sharpener, swing handle drives cutting tool group to rotate, cutting tool group drives axle sleeve and dial rotation, rotating disk gear shaft is rotated, gear shaft drives pencil to move in body, and when pencil touches cutting tool group, cutting tool group is cut pencil; After pencil sharper is good; pencil withstands cutting tool group, now, has larger resistance on pencil; gear shaft is owing to having frictional force thereby also having larger resistance with pencil; owing to being provided with spring between rotating disk and fixed mount, when gear shaft is subject to larger resistance when motionless, in dial rotation process, contact with gear shaft and be subject to reaction force; and then Compress Spring; make to occur skidding between rotating disk and gear shaft, pencil enters pen no longer inward, effectively protects pencil excessively not cut.This design preferably resolves the pen device that automatically enters of traditional pencil machine and does not feel that pencil cuts because of user, continue dial rotation, gear shaft still drives pencil inwardly to enter pen, pencil is excessively cut, cause the problem of unnecessary waste, simple in structure, easy to use, therefore obtain the extensive approval in market.
But in actual production process, because parts are more, complex structure, wastes time and energy during manufacture, during use, due to the interlock interlock of projection on rotating disk and gear shaft, during pencil rotation, speed is slower, and feel is stiff and noise is larger, fragile.
Utility model content
The technical problems to be solved in the utility model be current penknife automatically enter pen device complex structure, noise is larger, fragile, provide a kind of simple in structure, cut that pen speed degree is fast, time saving and energy saving, noiselessness, long-lived penknife automatically enter pen device.
For achieving the above object, the utility model adopts following technical proposals: a kind of penknife automatically enter pen device, comprise fixed mount and the rotating disk which is provided with, on fixed mount, offer sleeve joint hole, rotating disk is provided with axle sleeve, and described axle sleeve is located in sleeve joint hole rotationally, on fixed mount, be also articulated with power transmission shaft, power transmission shaft is rotation under the rotarily driving of rotating disk, offers uniform groove on described rotating disk, and rubber wheel and retaining sleeve are installed on power transmission shaft.
Between described rubber wheel and rotating disk, be provided with gap.
Groove on described rotating disk is located at the opposite side of axle sleeve.
Described rubber wheel is soft plastic wheel, and rotating disk is hard plastic glue rotating disk, and retaining sleeve 52 is software rubber sleeve.
Described rotating disk is provided with bulge loop, and bulge loop is positioned at axle sleeve one side and the same outside that is located in axle sleeve.
Adopt the utility model after said structure, output more uniform groove on rotating disk, load onto rubber wheel on power transmission shaft, when cutting, cutting tool group drives rotating disk, driven by rotary disc rubber wheel, and then makes software rubber sleeve friction pencil cut pen work; Between rubber wheel and rotating disk, be provided with gap, in cutting a process, comparatively fast, power transmission shaft also rotates comparatively fast, thereby cut pen speed degree, also accelerates in rubber wheel rotation; And rubber wheel adopts in manufacturing process, be soft plastic, rotating disk adopts hard plastic glue, and one soft one almost has not a particle of noise firmly in cutting a process; The utility model pencil can automatically go forward one by one or exit, both lighter, operation easy to use.
