Abstract
The utility model relates to pencil sharpeners, in particular to an automatic pencil feeding device for the pencil sharpeners. The automatic pencil feeding device comprises a support and a rotary disc which are arranged in a pencil sharpener housing, the rotary disc is movably mounted on the support, a through hole is formed in the centers of the support and rotary disc to allow a pencil holder to penetrate, the support is provided with two parallel bearings, each bearing seat is provided with a rotary shaft provided with a friction wheel and a transmission wheel, the rotary disc is driven through a lower transmission mechanism to rotate, the outer edge of the transmission wheel is provided with teeth, and the upper surface of the rotary disc is provided with a rack which is engaged with the teeth and which is in a ring shape. According to the automatic pencil feeding device for the pencil sharpeners, the transmission structure with the engaged teeth is adopted, skipping between the friction wheel and the transmission wheel and between the transmission wheel and the rotary disc can be eliminated, the mechanisms are capable of rotating with the transmission mechanism accurately, and pencil feeding and discharging efficiency is improved greatly.
Description
Technical field
The utility model relates to penknife, particularly a kind of automatic pencil feeding device for pencil sharpener.
Background technology
The pen clip feed arrangement of known penknife is all located at penknife hull outside, by two elastic guide rods, be positioned on housing, the spring force of mat elastic guide rod by penholder send into, operate comparatively loaded down with trivial details.For this reason, dealer has formerly also done suitable improvement, Chinese utility model patent has been announced a kind of " automatic pencil feeding device for pencil sharpener ", the patent No. is 201020647480.8, this scheme adopts wheel disc and rubber ring friction, band dynamic bearing by penholder send into, this scheme partial solution the problems referred to above of having determined, but be in use prone to the situation of advance and retreat pen difficulty and idle running, trace it to its cause is to be mainly embodied in following two aspects, the one, because each parts spacing is larger, between ebonite fluted disc and soft rubber circle, easy skid, cannot go forward one by one penholder; The 2nd, the contact-making surface of drive and friction pulley is planar structure, and coefficient of friction is little, between drive and friction pulley, easily skids, and in the time of drive idle running, friction pulley is motionless, causes the propelling action of penholder to complete.
Utility model content
The purpose of this utility model is to provide a kind of automatic pencil feeding device for pencil sharpener of the pen of can smooth and easyly advancing and retreat.
The purpose of this utility model is achieved through the following channels: a kind of automatic pencil feeding device for pencil sharpener, it comprises support and the rotating disk being loaded in penknife housing, rotating disk is movably installed on support, support and rotating disk central authorities are provided with the through hole passing for penholder, on described support, there are side by side two pairs of bearing blocks, one rotating shaft is installed on each bearing block, rotating shaft is provided with friction pulley and drive, described rotating disk drives rotation by the transmission mechanism of below, described drive foreign steamer is along being provided with the gear teeth, and disk upper surface is provided with the tooth bar that cast is arranged that is with gear teeth meshing.
As the further optimization of this programme, drive and friction pulley, near installation, are provided with curved on the contact-making surface of drive and friction pulley.
The utility model automatic pencil feeding device for pencil sharpener, the drive mechanism of employing engaged gears, is difficult for skidding between friction pulley and drive and between drive and rotating disk, and each mechanism can accurately follow transmission mechanism rotation, has greatly improved the efficiency of advance and retreat pens.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model integral installation structural representation;
Fig. 2 is that the utility model is automatically to pen device plan structure schematic diagram;
Fig. 3 is that the utility model is automatically to pen device side structure schematic diagram;
In figure, support 1, rotating disk 2, bearing block 3, through hole 4, rotating shaft 5, friction pulley 6, drive 7, the gear teeth 8, tooth bar 9, transmission mechanism 10, curved 11.
The specific embodiment
As Fig. 1, Fig. 2, shown in Fig. 3, the utility model automatic pencil feeding device for pencil sharpener, it comprises support 1 and the rotating disk 2 being loaded in penknife housing, rotating disk 2 is movably installed on support 1, support 1 and rotating disk 2 central authorities are provided with the through hole 4 passing for penholder, on described support 1, there are side by side two pairs of bearing blocks 3, one rotating shaft 5 is installed on each bearing block 3, rotating shaft 5 is provided with friction pulley 6 and drive 7, described rotating disk 2 drives rotation by the transmission mechanism 10 of below, described drive 7 foreign steamers are along being provided with the gear teeth 8, rotating disk 2 upper surfaces are provided with the tooth bar 9 that cast is arranged that is with the gear teeth 8 engagements.Drive 7 near installation, in order to prevent skidding between drive 7 and friction pulley 6, is provided with curved 11 on the contact-making surface of drive 7 and friction pulley 6 with friction pulley 6, for regulating friction force, plays the effect of automatic clutch.Drive 7 is accurate with the split design feel of rotating shaft 5, when cutting, and drive 7 automatic clutch, after fining away, drive 7 dallies automatically.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
