The problem of.
To achieve the above object, the utility model provides following technical scheme：
A kind of lower resistance microtome knife, including blade, the lower end of the blade are provided with blade, described blade rear end face
The rear end face for being provided with both sides above and below the boss of transitional function, boss is set to stress release section face and rear blade surface, described blade
Inclined lip surface is set on front end face and a section face is before pushed away, and lip surface and before push away and be provided with angle between section face.
It is used as further program of the utility model：The blade thickness is 12-15mm.
It is used as further program of the utility model：The angle of the rear blade surface and lip surface is 9~11 °.
It is used as further program of the utility model：The lip surface and the preceding angle pushed away between section face are 177 °.
It is used as the utility model further scheme：The angle of the stress release section face and blade is 5~6 °.
It is used as the utility model further scheme：The rear blade surface is provided with 24 ° of orifice 8 with lip surface bottom,
Its height is 3~8mm.
Compared with prior art, the beneficial effects of the utility model are：
Blade of the present utility model is novel in design rationally, and the extruding thrust of cutting edge and object fixed part can be greatly reduced
And frictional force, mitigate in slicing processes and damage is compressed and rubbed against to object tangent plane, reduce to the reaction force in slicing processes
Minimum, realizes the accurate, efficient of slicing processes and stable smooth.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer in Fig. 1~4, the utility model embodiment, a kind of lower resistance microtome knife, including blade 1, blade 1
Thickness is 14mm, and the lower end of blade 1 is provided with blade 2, and the rear end face of blade 2 is provided with the boss 3 of 10mm transitional functions, setting it is convex
Platform is suitable with the local compression deformation amount of recovery that fixed part during cutting is produced；Boss about 3 the rear end face of both sides be set to
Gap is 1.5mm stress release section face 4 and the high rear blade surfaces 5 of 35mm, and stress release section face 4 and the angle of blade 1 are 5 °, knife
Inclined 60mm lip surface 6 is set on the front end face of sword 2 and section face 7 is before pushed away, and lip surface 6 and before push away and be provided between section face 7
177 ° of angle, rear blade surface 5 and the angle of lip surface 6 are 10 °, and rear blade surface 5 is provided with 24 ° of orifice 8 with the bottom of lip surface 6,
3~8mm of its height,.
Such a blade coordinates the characteristics of orifice has self-sharpening, by the setting of blade surface and orifice angle, can make
The orifice and sword body of slicer are minimized during incision by the resistance of cigarette bag all directions, be difficult during use because
Abrasion rust.
The orifice of slicer is after object is splitted, and having completed the local compression deformation of cutting can realize that stress is released at once
Put, efficiently separating for follow-up knife face and fixed part can be achieved in the range of relatively short distance, slicer is reduced to greatest extent
Rear knife face and object fixed part between extruding thrust and frictional force, mitigate slicing processes to the extruding of object tangent plane and rub
Wear wound, minimize the reaction force of slicing processes, make every effort to realize the accurate and efficient of slicing processes.
Slicer of the present utility model selects high-strength alloy steel, is processed into using Digit Control Machine Tool, and it is special to coordinate
Technology for Heating Processing, it is ensured that while sword body hardness reaches 58+HRC, still maintain splendid toughness, by fine sharpening,
Highly sharp wear-resisting orifice can be obtained.Be not in wiredrawn edge, chipping phenomenon under normal service condition.With traditional slicer
Blade compares, and sharpens cycle stretch-out more than one times, it is adaptable to the industrial slicer of a variety of industries.
Test example
Industrial microtome knife of the present utility model, by the reality of 6 months on 2 sets of slicers of Kunming Cigarette Factory
Production run is verified, considerably enhances chipping qualities and stability.Compared with using conventional blades dicing effect：In flue-cured tobacco
On the smoked sheet width control system of cigarette bag section, the width control system standard of traditional microtome knife is：± 30mm, but still have often overproof
Situation occurs；And slicer of the present utility model is in production application, it can be ensured that smoked sheet width control system exists：± 10mm with
Interior, cigarette bag slice width realizes uniform stabilization, has prevented the generation of card cigarette disorderly closedown phenomenon, it is ensured that section continuity,
For smoked sheet, continuous cloth provides maximally effective ensure on belt feeder.Slicer can be provided uniformly for the direct ordering cylinder in downstream
Stable feeding, in continuous flow procedure, the peak shown in the flowed fluctuation curve map that ordering cylinder front end belt conveyer scale is monitored
Paddy maximum is that the first order moisture of tobacco workshop production line is precisely controlled creation no more than ± the 3% of setting flow
Optimal prerequisite.
Also demonstrated in the actual production operation of Changsha Cigarette Factory, it is right using industrial microtome knife of the present utility model
The width control system of smoked sheet and the operation stability lifting effect of equipment substantially, have prevented card cigarette machine halt trouble substantially.Particularly exist
Observe that sharp cutting edge structure design makes slicer in the slicing processes of the reconstituted tobacoo cigarette bag bigger than normal to section resistance
Incision resistance significantly reduces, and cutting-off process is smooth, and the slicer motor happened occasionally originally overloads the no longer appearance of phenomenon.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
