Description

A kind of tobacco leaf grading stem-butts cutting off cutter

Technical field

The utility model relates to a kind of tobacco leaf grading stem-butts cutting off cutter, belongs to tobacco redrying classification processing knife saw.

Technical background

Tobacco leaf grading is the prerequisite that tobacco leaf carries out modern industry redrying processing, tobacco leaf is distinguished according to certain industrial grading standard intraocular by its method, tobacco leaf after just baking is distinguished according to qualify requirements such as leaf color, growth site, oil content thickness, to adapt to the requirement of module proportioning redrying in modern tobacco leaf process.And the tobacco leaf of the one-tenth handle purchased from tobacco grower's hand in the face of tobacco commercial company, stem-butts to be drawn first exactly and untie, then could implement graded operation.According to relevant regulations, stem-butts must be that therefore this draws disconnected as the tobacco leaf tied up with regard to needing by stem-butts cutting off process by the tobacco bales ligation of the similar or lower slightly one-level of this tobacco leaf degree forming.Tobacco belongs to Solanaceae, and its passages through which vital energy circulates toughness after just examining moisture regain is comparatively strong, through finding actual production process investigation, is difficult to disposable cut-out stem-butts with small-sized knife saws such as general fruit knife, paper knives, and repeatedly cuts, draws and affect operating efficiency; And easily cut broken whole tobacco leaf with large-scale knife saws such as reaping hooks, can affect its quality, large-scale cutter inconvenience is simultaneously carried, and also there is potential safety hazard.

Summary of the invention

The purpose of this utility model is to provide a kind of tobacco leaf grading stem-butts cutting off cutter, and rationally, structure is simple, easily implements, easy to use for its structure.

The purpose of this utility model is achieved in that the blade of more than handle of a knife is interior warp architecture, and interior curved saw blade is equipped with in interior curved side, and blade top is hinged with interior bending band cutting edge point of a knife, and articulated position is provided with the locked button of point of a knife.

The interior curved side of blade is with notch, and the saw blade of upper and lower two ends respectively with installing hole inserts in notch, with the installing hole corresponding with saw blade on blade, saw blade and blade is fixed by fixed screw, when being convenient to change after saw blade corrosion or wearing and tearing; The introversion angle of blade and saw blade is 25 ~ 30 °, and the introversion angle of point of a knife is 20 ~ 25 °.

The inner side of handle of a knife and blade connecting position fills bossed safe handle, and when preventing from holding cutter, palm slides to blade, ensures the safety of user; The Surface Machining of handle of a knife has anti-skidding rag, handle of a knife slippage hand when preventing firmly.

Saw blade 6 thickness is 0.5 ~ 0.70mm, and on saw blade 6, sawtooth number is 33 ~ 37 teeth.

The jointed shaft of point of a knife and blade is screw jointed shaft, equally when being convenient to change after point of a knife corrosion or wearing and tearing.

The beneficial effects of the utility model are: the utility model has done Curve guide impeller to stem-butts cutting off cutter used in extension set stem-butts cutting off process, and blade is changed into the design of interior musical form, blade is divided into knife saw portion and nose part, and can dismantle; Interior musical form design can carried out stem-butts drawing more easily stressed in stem-butts cutting off process; Saw blade on blade can split the passages through which vital energy circulates of stem-butts by sawed-off or saw easily, and the introversion point of a knife sword of nose part can be scratched fast and be sawed the stem-butts split, and the durability of this device obtains enhancing simultaneously; Nose part hinged adduction design also make its security be improved.This stem-butts cutting off cutter also can be applied in industries such as a lot of similar tobacco leaf extension set stem-butts cutting off, packaging dismountings, can obtain good benefit.

Accompanying drawing explanation

Further illustrate below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of the utility model tobacco leaf grading stem-butts cutting off cutter.

In figure: handle of a knife 1, anti-skidding rag 2, safe handle 3, blade 4, notch 5, saw blade 6, fixed screw 7, fixed screw 8, point of a knife 9, point of a knife sword 10, point of a knife ridge 11, the locked button 12 of point of a knife, screw 13.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further details.

The shank section (handle of a knife 1, safe handle 3) that this tobacco leaf grading stem-butts cutting off cutter comprises, knife saw portion (blade 4, saw blade 6, fixed screw 7,8), nose part (point of a knife 9, screw 13, point of a knife is locked buckle 12).The handle of a knife 1 of shank section is carved with anti-skidding rag 2, and there is safe handle 3 inner side that handle of a knife connects knife saw position, and when preventing from holding cutter, palm slides to blade.In knife saw portion and nose part adopt, musical form designs, the blade 4 in knife saw portion and saw blade 6 introversion 25 ~ 30 °.Saw blade 6 can dismounting and change, saw blade 6 has 2 screw installing holes, fixes with fixed screw 7,8 and blade 4.The point of a knife 9 of nose part is carved with screw hinge hole, and hinged by fixed screw 13 and blade 4, articulated position is also configured with the locked button 12 of point of a knife of spring-like cutter, and after taking off fixed screw 13, nose part can be dismantled down and carry out polishing or changing.After the locked button 12 of point of a knife is allocated to locking position, point of a knife 9 and blade 4 are combined closely, irremovable, ensure that normal use; And after the locked button 12 of point of a knife is allocated to unlocked position, point of a knife can adduction, prevents from producing potential safety hazard when putting to surrounding people.

The operation principle of this device is: hold handle of a knife 1, safe handle 3 is withstood outside forefinger, thumb rides over the other side of handle of a knife, the sawtooth of the saw blade 6 in stem-butts cutting off knife saw bar portion is pressed close to need in the stem-butts of stem-butts cutting off, pull at and draw, sawtooth, by sawed-off for the sturdy main warp arteries and veins of stem-butts, then taken advantage of a situation down and is drawn, by the point of a knife sword 10 on nose part point of a knife 9 by being drawn disconnected by sawed-off stem-butts, reach the object dissolving stem-butts.

When knife saw portion saw blade 6 gets rusty, after passivation or breakage, takes off the holding screw 7,8 on blade 4, just saw blade 6 can be taken off from notch 5 and carry out polishing or changing.After new saw blade 6 is mounted to notch 5, tighten holding screw 8,7.

When the point of a knife sword 10 on point of a knife 9 weares and teares, gets rusty or after passivation, unclamped by the screw 13 on blade 4, just point of a knife 9 can be taken off polishing, after polishing is loaded onto, holding screw 13.
