Abstract

The utility model relates to an electric pencil sharpener which is designed by the principle of mechanical drive and is characterized in that a sharpening part is composed of three blades which are respectively fixed to a sharpener shelf. One end of the sharpener shelf is connected with a drive shaft. A driven wheel on the drive shaft is connected with a transmission wheel on a motor shaft through a transmission belt. The other end of the drive shaft is provided with a grinding wheel. The utility model has the advantages of simple structure and reasonable design. The electric pencil sharpener not only enhances the quality and the speed of sharpening a pencil, but also enhances the practical use rate of the pencil. The waste of the pencil is decreased to the lowest degree and resource can be largely saved.

Description

Electric pencil sharpener

The utility model relates to a kind of electric pencil sharpener that utilizes the design of machine driving commercial weight.

Pencil is that we modal a kind of article in daily life, and this almost permeates at our everyone first sphere of life, no matter is work, and still study does not all lack, artist especially, and the designer, students in middle and primary schools, even the workman is the article of indispensability.But for many years, people have a slight difficulty, and that sharpens a pencil exactly.It is of a great variety to sell the pencil-knife of praising at present on the market, but kind is single, that must be done with hand exactly, because the firmly size of hand is inhomogeneous, the pencil of cutting out one is that outward appearance is difficult to see, the 2nd, be easy to disconnected core, and the 3rd, the lead for retractable pencil length of cutting out is difficult to grasp, inconvenience during use, four Xiao speed is also very slow.People had invented a kind of manual pencil sharpener again afterwards, but owing to rotate what cut that pen still relies on is the thrust of hand, still exist the uneven problem of exerting oneself, the excessive easily disconnected core of exerting oneself, firmly too small, skin is respectful does not get off for pencil wood, and with the pencil that this pencil sharpener is cut out, in fact pen core can break.Often a pencil is just improper because of sharpening a pencil, and very fast the loss.Its utilization rate I'm afraid limit 1/2 less than, the waste that causes is startling.In order to dwindle this startling numeral, many knowledgeable people have thought that thousand and one way solves this slight difficulty, such as there being the people to find out the method for non-sharpenning pencil; propelling pencil has so just appearred; with the low skin pencil that hand tears, the former cost is too high, then has the lead of protection still disconnected easily.The latter is subjected to also very difficult large-scale popularization of problem and alternative wooden pencils such as environmental limit because crust is too soft.

The purpose of this utility model utilizes the machine driving commercial weight to design a kind of electric pencil sharpener exactly, solves the uneven problem of exerting oneself when manually cutting Wood pencil.

The electric pencil sharpener of the utility model design is made of power section, running part, cutting tip and power unit four parts.Power section is to be become by a micro-electromechanical.Power section is to be made of the follower that is contained in the drive on the motor shaft and be contained on the driving shaft.Cutting tip is to be made of three blades and emery wheel.When turning on the power switch, micromachine is started working, and it drives and passes the sleepy rotation of taking turns, and the belt that connects follower is passed to follower with rotatory force, and follower drives the driving shaft rotation, thereby drives blade and emery wheel rotary work.

The electric pencil sharpener of the utility model design is simple in structure, reasonable in design, owing to used Rational structure electronic and three blades, make when sharpening a pencil firmly very even, the disconnected probability of pencil sharper is just very little, and the sharpening of pen core is changed into the emery wheel mill, makes to cut firmly to become buffing, also make pen core in use owing to the rapid change shape firmly that sharpens a pencil, cut a pencil and only need several seconds.Improved the quality and the speed of cutting pen,, can be country and save a large amount of timber and graphite though cost than general little knife up, has improved the utilization rate of pencil widely.

With reference to the accompanying drawings electric pencil machine structure described in the utility model is carried out detailed narration below.

Accompanying drawing: electric pencil sharpener structural representation

Wherein: 1. the plumbous hole of follower 2. removable covers 3. emery wheels, 4. driving shafts 5. mill 6. lead powder are collected and are closed 7. driving-belts, 8. drives, 9. tool head box, 10. batteries and close 11. knife rests, 12. blades, 13. hold-down screws, 14. sliding rings, groove 15. and cut a hole 16. wood chips and collect and close 17. motors, 18. motors and close the plumbous frame of 19. power switches 20. contacts, 21. mills

Embodiment

Tool head box (9) inside is separated into four spaces, they be respectively the bottom battery close (10), the plumbous frame of mill (21) that closes dividing plate perpendicular to battery is separated into the tool head box middle part that motor closes (18) and (6) are closed in the lead powder collection, a right angle dividing plate links to each other with the tool head box sidewall, and motor is closed (16) by only just being divided into the wood chip collection that can adorn the pencil wood chip.Motor (17) is contained in motor closes, and adorns a drive (8) on motor shaft.At the tool head box inwall, wood chip is collected and to be closed side and open one and cut a hole (15), the hole is provided with sliding ring and sliding tray (14), opposite side wood chip that knife rest closes collect close above open a mill plumbous hole (5), driving shaft (4) one ends dress emery wheel (3), the other end links to each other with knife rest (11), and a follower (1) is adorned in the centre, then driving shaft is fixed on the plumbous frame of mill, belt driving band (7) passes wood chip and collects and to close and lead powder is collected the passageway that forms between closing follower and drive are linked together.Three blades are separately fixed at by hold-down screw (13) to be hated on the frame, and the end just in time is stuck in the sliding tray.Contact (2) was equipped with at two during battery closed, and adorned a power switch (19) on the tool head box, and the tool head box top is a removable cover (2), can open at any time wood chip and lead powder are poured out.

Claims

1. electric pencil sharpener that constitutes by blade and motor, it is characterized in that: its cutting tip is to be made of three blades that are separately fixed on the knife rest, knife rest links to each other with driving shaft one end, follower is contained on the driving shaft, by driving-belt it is linked to each other with drive on the motor shaft, emery wheel is contained in the other end of driving shaft.
