Abstract
Disclosed is a multi-functional electric drawing pencil sharpener which driven by a miniature direct current electric motor and is slowed down to transfer by a gear system. Four different cutting tools and grinding tools are capable of cutting pencils and lead cords to meet the various technical requirements of drawing. In particular, under the control of mechanical assistance, the utility model is capable of cutting out desired flat-mouth lead cord for drawing thick solid line, and the thickness and length completely conforms to the technical requirements. The utility model has the advantages of time saving, sanitation and cleanness, small size and convenience for carrying.
Description
The utility model is a kind of pencil sharpener of cutting the system drawing pencil.
The desired flat lead for retractable pencil of chewing during the general manual pencil sharpener system of can not cutting is drawn then uses the manual system of cutting of pocket knife as the flat lead for retractable pencil of chewing of the system of will cutting, and is not only time-consuming, easily broken, but also easily do dirty hand and figure tool etc.
The system of cutting that is intended to the utility model satisfies the pencil of the required various specification requirements of drawing, the electric device of lead for retractable pencil.
The utility model is finished by following mode: motor (4) rotates after connecting power supply, and the deceleration transmission system that forms by gear and axle drives four part work.First and second part is the deceleration transmission system driven rotary work that pencil sharpener frame (8), (13) are formed by gear (27), (1), (3), (10), (7), (12) and axle (11), (23).Third part is: serrated knife (17), (18) are by gear (27), (1), (25), (2), (19) and axle (23), (20), (16) driven rotary.So as long as pencil is sent in the six prismatic holes gradually, blade (14), with the wooden part of the rotary cutting pencil of pencil sharpener frame (13).Pencil continues to advance, and then the two edges of lead for retractable pencil saw is removed in serrated knife (17), (18), the desired width of heavy line during the residue width charts just.When lead for retractable pencil is reached 8 millimeters by saw, lead for retractable pencil will back down a normally closed interlock (32), cut off motor power, stop cutting automatically.As draw and need fine line or when writing, then operate clutch handle, again pencil to be sent in another six prismatic hole, blade (5) is whittled into pencil lead coniform with the rotation of pencil sharpener frame (8).Emery wheel (21) is used for the required various difform lead for retractable pencils of grinding.PA-system can the ejected electron music during cutting.
The utility model multifunctional electric pencil sharpener adopts machinery control cutting, and firmly evenly, lead for retractable pencil is frangibility not, and can shorten and cut the system time, can concentrate swarf, repeatedly uses once and removes.Sanitation and hygiene, long service life, volume is little, is easy to carry.
Now in conjunction with the accompanying drawings invention is described in further detail.
Fig. 1 is the top plan view of the utility model concrete structure.
Fig. 2 is a front view.
Fig. 3 is the control schematic diagram of motor and PA-system.
Be an embodiment of the present utility model below:
Housing of the present utility model becomes a rectangular enclosure with shell (29) with bolting by shell (28), it is characterized in that having in the housing bracing frame of two band annulus and baffle plate, the effect of baffle plate is to block the pencil wood chip to splash everywhere in housing, base plate has correspondingly been opened two mouths, is furnished with removable cover, its effect is storage, clear plumbous crumb, the supporting seat that support motor (4) are arranged, the housing inboard have one embed the axle (11) cylindrical hole, the positive inboard of housing has two and embeds pencil sharpener frame (8), (13) cylindrical hole, the outside, hole is six prismatic holes, diameter is 6～9 millimeters, its effect is to overcome the swing of pencil when cutting, and six prismatic holes and cylindrical hole are the same garden hearts.There is a through hole on the housing right side, an and protruding cuboid cavity, its effect is to cover emery wheel (21), avoids other object to contact with it, prevents that plumbous bits from splashing everywhere, be convenient to repeatedly use once and remove, the grinding workbench is provided, and housing has three through holes, does the voltage-stabilized power supply hole respectively, switch hole, clutch gear operator delthyrium.Be provided with the position of dry cell chamber and Music centre loudspeaker in the housing.Whole housing is made by plastic material.
Miniature cocurrent electromotor (4) is fixed on the base, on the axle (11) bossing is arranged, and the one top embeds in the hole, the positive inboard garden of housing, and the other end is fixed on the supporting seat (9).Axle (16), (20), (23) are fixed on supporting seat (24), (26), and its supporting seat is fixed in base plate one groove by screw.Housing through-hole is worn on one top of axle (23), stretches into shell inner cavity, and gear (27) is fixed on the motor shaft, and gear (1), (25) and emery wheel (21) are fixed on the axle (23).Bevel gear (3) and gear (10) are fixed on the axle (11), and bevel gear (3) makes to turn to and changes 90 degree.The interior garden of gear (10) has a groove, and its negative area is meshed with the bossing of axle (11), and the operation clutch handle can move axially gear (10), has only the work of a pencil sharpener frame thereby can make at every turn, saves the energy.Umbrella or garden sheet shape serrated knife are adopted in serrated knife (17), (18), its effect is the sawing lead for retractable pencil, serrated knife (17), (18) are separately fixed on axle (16), (20), can regulate distance between two serrated knife by adjusting distance between supporting seat (24), (26), so that reach the required thickness of cutting lead for retractable pencil.
Pencil sharpener frame (13), (8) cast with plastics.It is characterized in that pencil sharpener frame (13), endoporus are made of garden cylindricality and garden platform shape.5 millimeters of garden column lengths, it is the diameter of lead for retractable pencil that the long 22-24 millimeter of garden platform shape, platform shape hole Xiao Yuan correct.Rectangle single dege blade (14), (5) are used bolt (6), (15) to be fixed on pencil sharpener frame (13), (8) respectively and are had on the plane of a screw, its cutting edge each point and garden platform or garden awl bus coincide, the groove of pencil sharpener frame (13), (8) one ends projection garden ring is meshed with garden ring on the housings support frame respectively, another garden styletable embeds respectively in the garden post of shell inboard, and its post hole, garden and pencil sharpener frame (13), (8) are same axial lines.So both made pencil sharpener frame location, and can make the pencil sharpener frame do circumferentially to rotate stably again along its axial line.Bossing on pencil sharpener frame (13) and (8) is meshed with gear (7), (12) interior garden negative area, and the rotation of gear (7), (12) promptly drives the rotation of pencil sharpener frame.
