Description
[technical field]
The present invention relates to a kind of electric pencil planer.
[background technology]
Traditional electric pencil planer need manually send pen, and needs manually firmly to hold with a firm grip pencil in the pencil working angles, also need manually extract pencil after cutting finishes, and uses very inconvenient.
[utility model content]
The objective of the invention is to overcome above-mentioned technical defective, provide a kind of and can realize pencil auto-feed and the electric pencil planer that withdraws from automatically.
The invention discloses a kind of propelling pencil and dig, comprise motor, transmission mechanism, automatic cutting mechanism is characterized in that: described propelling pencil digs and further comprises an automatic advance and retreat mechanism and slip ring changement.
Compared with prior art, the present invention has following characteristics:
Because pencil advance and retreat motion path is provided with intermeshing internal thread swivel nut and the movable double-screw bolt of external screw thread, the rotating campaign of swivel nut is converted to the advance and retreat back and forth movement of movable double-screw bolt, and the auto-feed that realizes pencil effectively reaches to be withdrawed from automatically.
Owing to be respectively arranged with elastic sheet switch at the swivel nut two ends, movable double-screw bolt circumference is provided with two axis of guides, and elastic sheet switch and the movable double-screw bolt axis of guide link, thereby has guaranteed the displacement of movable double-screw bolt back and forth movement, and the switch connection problem in having avoided rotatablely moving.
Owing to be provided with into moving switch of style of writing and two metal slip rings on knife rest, touch switch and slip ring are realized rotatablely moving synchronously, and slide bar compresses slip ring and long-term and slip ring generation friction, thereby solve the switch connection problem in rotatablely moving effectively.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:

The specific embodiment
A kind of propelling pencil digs, the transmission mechanism that comprises motor 22, driven by motor 22, cutting mechanism automatically, an advance and retreat mechanism automatically, slip ring changement.
With reference to figure 1, the transmission mechanism that described motor 22 drives comprises fiery ox 23, electron plate 19, gear train 21, support 18, knife rest 15, swivel nut 11, movable double-screw bolt 5.Motor 22 drive gear set 21, knife rest 15 are socketed on the ultimate gear of gear train 21, and knife rest 15 connects swivel nut 11 simultaneously, and so movable double-screw bolt 5 is done back and forth movement under the driving of swivel nut 11.Be provided with a through hole in the described movable double-screw bolt 5, this through hole is the inlet of pencil cutting movement.
With reference to figure 1 and Fig. 4, described automatic cutting mechanism comprises knife rest 15, hobboing cutter 31, gear ring 30.Hobboing cutter 31 connects together with knife rest 15, make hobboing cutter 31 to rotate with knife rest 15, hobboing cutter 31 1 ends are connected with a hobboing cutter gear (figure does not show), this hobboing cutter gear is meshed with gear ring 30, thereby make hobboing cutter 31 produce circular motion, finish the cutting movement of pencil around the pencil that enters knife rest 15 centre bores.
With reference to figure 2 and Fig. 3; a described automatic advance and retreat mechanism comprises swivel nut 11; coupling ring 10, travel switch, movable double-screw bolt 5, rubber school ring 3, axle 7, axle 29, reset switch, fixed cap 1; described travel switch comprises shell fragment 8, shell fragment 9, becket 6; stroke in order to restraint double-screw bolt 5; described reset switch comprises shell fragment 2, shell fragment 30, becket 4, in order to the initial position of geocoded activity double-screw bolt 5.Swivel nut 11 rotates with knife rest 15, and pass through screw-threaded engagement with movable double-screw bolt 5, movable double-screw bolt 5 garden Zhou Kaiyou two through hole, difference socket axle 7 and axle 29, movable double-screw bolt 5 both ends of the surface are fixed with becket 4 and becket 6 simultaneously, its endoporus socket rubber ring 3, the becket 4,6 and the axle 7,29 that are positioned on the movable double-screw bolt 5 keep certain distance respectively. Shell fragment 2,30 is socketed in axle 7,29 upper end respectively, and coaxial 7,29 be fixed on the fixed cap 1 together, and shell fragment 8,9 is socketed in the lower end of axle 7,29 respectively simultaneously, and coaxial 7,29 are fixed on the coupling ring 10 together.The rotation of swivel nut 11 causes movable double-screw bolt 5 to make back and forth movement on axle 7,29 like this, and is range to touch shell fragment 8,9, and touching shell fragment 2,30 is initial position.
With reference to figure 4, described slip ring changement comprises the touch switch group that is fixed on the knife rest 15 and the first slip ring group, the second slip ring group, described touch switch group comprises slide block 12, stage clip 13, switch 14, pencil is entered by knife rest 15 centre bores, force the slide block 12 under stage clip 13 pressure outwards to move, trigger touch switch 14.The described first slip ring group comprises slip ring 24, slide bar 17, stage clip 16, slip ring 24 is socketed on the knife rest 15, rotate with knife rest 15, slide bar 17 compresses slip ring 24 under stage clip 16 pressure, long-term and slide bar 17 generation frictions when slip ring 24 rotates, switch 14 connects slip ring 24 by lead (figure does not show) simultaneously, slide bar 17 connects electron plate 19 by lead (figure does not show), realize the commutation transfer of switch connection, the described second slip ring group comprises slip ring 25, slide bar 26, stage clip 27, and its operation principle is identical with the first slip ring group.
Although the present invention is disclosed by above example, but scope of the present invention is not limited thereto, do not departing under the condition of the present invention design, more than each element or construct available under the similar or equivalent element understood of technical field personnel construct or replace.
