Abstract
The utility model relates to a pencil sharpener with an annular oblique-edge continuous-casting cutter head. The utility model comprises a case body, a scrap collection box, a clamping box, a cutter frame, an inner gear, a cutter shaft, a cutter head, a planet wheel and a handle. The utility model is characterized in that the spiral angle of a spiral oblique cutter edge on the surface of the annular cutter head which is fixedly arranged at the middle part of the cutter shaft is twenty-nine DEG. The screw pitch is thirty MM. The slope of the oblique cutter edge is thirty DEG. The edge-tip angle of the oblique cutter edge is twenty DEG. The utility model has the advantages of reasonable structure, simpler manufacture, low cost, high cutting quality and small cutting force.
Description
The utility model relates to the oblique sword continuous casting of a kind of annular type cutter head pencil sharpener, is applicable to sharpen a pencil.
The hand-rail type pencil sharpener of selling on the market, its appearance and size and structure are basic identical, and cutter head is the annulus body, helical angle at the oblique blade of the lip-deep spirality of annulus body cutter head is 70 °-85 °, and pitch is 90mm, and it is low that this product is made efficient, the production cost height also poorly uses.
The purpose of this utility model is that traditional pencil sharpener is improved, and makes its structure more reasonable, makes and more becomes simple, and production cost is low, and cutting force is little, the cutting quality height.
The oblique sword continuous casting of a kind of annular type cutter head pencil sharpener comprises:
Casing, this casing supporting pencil sharpener, bottom half is provided with fixing hole, and with clip, the casing left side is provided with circular hole, and the upper right side of casing is provided with endoporus;
Bits collecting box, this bits collecting box is the box of drawer type structure, places bottom in the casing, can extract out from the casing left side;
The clamping case, this clamping case is packed in casing left outer top, twitches about energy, is provided with the compression spring of clamping pencil in the clamping case;
Knife rest, this knife rest is provided with a pair of circular hole, and its knife rest left side is enclosed within the circular hole in casing left side;
Internal gear, this internal gear are the round casing that is provided with the locating wedge platform, its outside circle cover face and casing upper right side endoporus Joint, and the right side endoporus of internal gear is sleeved on the right side of knife rest;
Cutter shaft, these cutter shaft two ends are contained in a pair of circular hole of knife rest;
Cutter head, this cutter head is the annulus body, is sleeved on the middle part of cutter shaft;
Planetary gear, this planetary gear and cutter head continuous casting together, the engagement of its planetary gear and internal gear;
Handgrip, this handgrip are packed on the little axle of knife rest one end;
It is characterized in that: the helical angle that is packed in the oblique blade of spirality on the annulus body cutter head surface at cutter shaft middle part is 29 °, and pitch is 30mm, and tiltedly the gradient of blade is 30 °, and tiltedly blade blade tip angle is 20 °.
Because adopt technique scheme, the utility model structure is more reasonable, to make and more become simple, production cost is low, and cutting force is little, and cutting quality is good.
Fig. 1 is the utility model structure chart.
Fig. 2 is cutter head structure figure.
Fig. 3 is the cutter head sectional drawing.
Fig. 4 is the A-A profile of Fig. 2.
In conjunction with the accompanying drawings the utility model is further described as follows:
The oblique sword continuous casting of a kind of annular type cutter head pencil sharpener is the improvement to prior art, comprising: casing 1, and this casing supporting pencil sharpener, bottom half is provided with fixing hole, and with clip, the casing left side is provided with circular hole, and the upper right side of casing is provided with endoporus; Bits collecting box 2, this bits collecting box is the box of drawer type structure, places bottom in the casing, is used to collect the wood chip that cuts, when wood chip was full of bits collecting box, bits collecting box can be extracted out from the casing left side, outwells wood chip; Clamping case 3, this clamping case is packed in casing left outer top, twitches about energy, is provided with the compression spring of clamping pencil in the clamping case; Knife rest 4, this knife rest is provided with a pair of circular hole, and its knife rest left side is enclosed within the circular hole in casing left side, and the right side is enclosed within the endoporus of internal gear, and knife rest is spatial rotational under handgrip drives; Internal gear 5, this internal gear are the round casing that is provided with the locating wedge platform, its outside circle cover face and casing upper right side endoporus Joint, and by locating wedge platform location, the right side endoporus of internal gear is sleeved on the right side of knife rest; Cutter shaft 6, these cutter shaft two ends are contained in a pair of circular hole of knife rest, are used for supporting cutter head; Cutter head 7, this cutter head is the annulus body, is sleeved on the middle part of cutter shaft; Planetary gear 8, this planetary gear and cutter head continuous casting together, the engagement of its planetary gear and internal gear; Handgrip 9, this handgrip are packed on the little axle of knife rest one end; It is characterized in that: the helical angle that is packed in the oblique blade of spirality on the annulus body cutter head surface at cutter shaft middle part is 29 °, and pitch is 30mm, and tiltedly the gradient of blade is 30 °, and tiltedly blade blade tip angle is 20 °.
When desiring to sharpen a pencil, an end of pencil is put into the clamping case, pencil can left and right sides tap in the clamping case, and by the effect clamping pencil of compression spring.When handgrip rotates, drive knife rest, cutter head, planetary gear rotate together, because of internal gear is the upper right side endoporus that is packed in casing, so internal gear maintains static, and planetary gear rotates along internal gear, drives the cutter head high speed rotating, and pencil is under the compression spring effect simultaneously, also feeding is given lentamente, realizes cutting.Cutting finishes, the limiting stand on the pencil-lead contact knife rest, and pencil no longer feeds.Cutter head idle running, the power on the handgrip obviously reduces, and an at this moment bright pencil is cut fully, takes out pencil, has cut a pencil and has needed 10 seconds, the cutting quality height.
