Description
Technical field
The present invention relates to a kind of schooling apparatus, particularly relate to a kind of automatic pencil-sharpener of propelling pencil lead core.
Background technology
Along with the continuous attention of people to environment, various environment protection type pencils arise at the historic moment.As propelling pencil, not only environmental protection but also convenient.But it is easily broken that the propelling pencil lead for retractable pencil is too carefully write, and lead for retractable pencil is crossed slightly then cutting trouble, manually cut inconvenient and easily broken core, and pencil sharpener not really is applicable to propelling pencil, particularly artificial pencil sharpener, because firmly unbalanced, and frangibility lead for retractable pencil more when volume is cut.Therefore, the use of propelling pencil is difficult to be extensive use of owing to not cutting the lead for retractable pencil instrument preferably.
Summary of the invention
The objective of the invention is is at above-mentioned the deficiencies in the prior art, and a kind of automatic pencil-sharpener of propelling pencil lead core is provided.This volume sharpener can be rolled up automatically and cut the propelling pencil lead for retractable pencil, and is easy to use and reliable, simple in structure, frangibility lead for retractable pencil not, cutting quality height.
Technical scheme of the present invention comprises, body is located at the pencil guide hole on the body, be connected in the hob head of body, be connected in the hobboing cutter that is provided with the hobboing cutter gear on the hob head, be arranged with a ring gear on the described hobboing cutter gear, described hob head is connected with automatic drive.
Described automatic drive comprises drive motors and corresponding electric-controlled switch, is connected in the travelling gear of hob head, be connected to this travelling gear and drive motors axle by worm screw, worm-wheel shaft, and the Worm gear mechanism that constitutes of worm-gear toothing assembly.
Described electric-controlled switch is the position switch of being located on the described pencil guide hole.
Described position switch comprises that its two ends are respectively equipped with anti-decylization parallel connection and lead in the guide pipe of described pencil guide hole, is positioned at guide pipe, which is provided with the feeler lever that supports bulge loop, is located at the spring on the described feeler lever, and corresponding dynamic and static contact.
Described hobboing cutter blade limit is parallel with the axis of hobboing cutter, and the axis of described hobboing cutter favours axis one angle of described hob head.
Described hobboing cutter blade limit favours described hobboing cutter axis one angle, and described cutter shaft line parallel is in described hob head axis.
Described body is provided with a measured hole.
Propelling pencil lead for retractable pencil volume sharpener of the present invention is easy to use and reliable, simple in structure.Even more ideal for the propelling pencil result of use of lead for retractable pencil more than 0.7-1.0.Because hobboing cutter blade direction is pointed to the tangential direction of lead for retractable pencil all the time, thereby lead for retractable pencil is cut and is different from the grinding method of general pencil sharpener.Particularly adopt to drive volume automatically and cut, it is even that its depth of cut and volume are cut dynamics, thereby cutting effect is good, frangibility lead for retractable pencil not when volume is cut.Simultaneously owing to be provided with the lead for retractable pencil instrument connection, cut as long as roll up according to quantitative length, lead for retractable pencil can avoid waste.
Description of drawings
Fig. 1 is one embodiment of the invention theory structure schematic diagram.Fig. 2 is hobboing cutter and a hob head theory structure schematic diagram in another embodiment of the present invention.
The specific embodiment
Now also the invention will be further described in conjunction with the accompanying drawings by embodiment.As shown in Figure 1, among first kind of embodiment of the present invention, as shown in Figure 1: worm screw 24 is installed on the axle of drive motors 25, is meshing with each other with worm gear on the worm-gear toothing assembly 22.Worm-gear toothing assembly 22 is fixed on the main body 4 by worm-wheel shaft 23, and the gear of worm-gear toothing assembly 22 is meshing with each other with the travelling gear 20 that is fixed on the hob head axle 15 of hob head 5.
Body is made up of main body 4 and cover plate 11, hob head 5 is movably connected on the main body 4 through hob head axle 15, hobboing cutter 18 blade limits 26 are parallel to cutter shaft 17, hobboing cutter 18 favours hob head axis one angle through cutter shaft 17 with hobboing cutter 18 axis and is movably connected on the hob head 5, and the hobboing cutter gear 19 that is fixedly arranged on the cutter shaft 17 with cutter shaft 17 coaxial lines is meshing with each other with the interior ring gear 3 that is fixedly arranged on the main body 4.Pencil guide hole 16 is fixedly arranged on the cover plate 11 with hob head 5 coaxial lines and corresponding to hobboing cutter 18, and shape and size that the size of pencil guide hole 16 and shape and propelling pencil body 13 insert the part of pencil guide hole 16 adapt.
One end of the guide pipe 28 of position switch is fixedly arranged on a sidewall of pencil guide hole 16 and UNICOM in pencil guide hole 16; The anti-decylization that is positioned at pencil guide hole 16 1 ends on the guide pipe 28 is the anticreep bulge loop 2 that is fixed on guide pipe 28 inwalls, the anti-decylization of its relative other end is for being threadedly connected to the plug formula anticreep bulge loop 8 of guide pipe 28, and the appearance wall is provided with and is with a spring 9 on the feeler lever 27 of supporting bulge loop 10 and is located in the guide pipe 28 corresponding to the extending part of anode copper sheet 6 and grows in guide pipe 28 two ends.Static contact 7, movable contact spring 6 are installed on the main body 4 corresponding to feeler lever 27.
The operation principle and the course of work of the electronic volume core of propelling pencil lead for retractable pencil cutter are as follows:
Propelling pencil 13 is inserted in the pencil guide hole 16, when the pen of propelling pencil 13 is bored feeler lever 27 medial extremitys of inclined-plane contact position switch, propelling pencil 13 just feeler lever 27 to extrapolation, movable contact spring 6 is contacted with static contact 7, battery in the battery compartment is drive motors 25 power supplies through lead 21, motor 25 rotations drive the central axis rotation of hob head 5 around lead for retractable pencil 14 after worm screw 24, worm-gear toothing assembly 22 and travelling gear 20 slow down; And the hobboing cutter gear 19 in the hob head 5 is meshed with ring-like internal gear 3, when hob head 5 centers on the central axis rotation of lead for retractable pencil 14, drives hobboing cutter gear 19 and hobboing cutter 18 rotations.When propelling pencil 13 continued inwardly to insert, the hobboing cutter 18 of rotation began to cut lead for retractable pencil 14; When the inclined-plane in the inclined-plane of the nib of the propelling pencil 13 contact propelling pencil guide hole 16, lead for retractable pencil 14 has been cut, and transfers to propelling pencil 13, and the feeler lever 27 of position switch resets by spring 9, and dynamic and static 6,7 is separated, and drive motors 25 stops operating, and finishes to roll up and cuts.
Hobboing cutter blade limit 26 favours the size of the center line angle of hob head 5 and determines with the tapering of the required cutting of lead for retractable pencil.Cover plate 11 is provided with a lead for retractable pencil measured hole 12, and to measure the length and the size of lead for retractable pencil, the length that volume is cut lead for retractable pencil is the effective length of hobboing cutter blade.
In second kind of embodiment of the present invention as shown in Figure 2, hobboing cutter 18 blade limits 26 favour axis one angle of cutter shaft 17, and both axis of cutter shaft 17 and hobboing cutter gear 19 parallel with the axis of hob head axle 15 to be eccentric in hob head axle 15 1 distances and are connected on the hob head 5.
