Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing
Go out all other embodiments obtained under the premise of creative work, shall fall in the protection scope of this application.
A kind of cut-off knife of strip cutting machine described herein, cut-off knife 100 include integrally formed cutter hub 11 and are located at
Notch 15 on cutter hub 11, wherein, the cutter hub 11 is string configuration, and the knife bottom 12 of 11 bottom side of cutter hub is a plane, knife
The knife spine 13 at 11 top of body is also planar structure, and knife bottom 12 is upwardly extended collectively constitutes solid cuboid column knot with knife spine 13
Structure, 12 top end of knife bottom extend the point of a knife 14 formed with 13 top of knife spine for cutting cloth obliquely；It is beaten with integration
Mill forms overall structure, and intensity is higher, and cutting property stiff stability is high, has lasting service life, be easily installed with it is fixed
Effect.
In the embodiment of the present application, the spool b of cloth rotates counterclockwise, by cut-off knife 100 gradually to spool b's
Center is stretched into, and then cuts the cloth that cloth forms web-like.
Shown in Fig. 1 to Fig. 4, a kind of cut-off knife of strip cutting machine, cut-off knife 100 is used including integrally formed cutter hub 11
Top is formed knife edge structure, and then realize the structure of blade by the metal derby of integrated column or block structure by polishing,
The cutter hub 11 of blade-shaped structure is greatly enhanced, stability is stronger, and have high intensity cuts effect.
Notch 15 on the top of block-like cutter hub 11 is set, web-like cloth is cut by notch 15, wherein,
The cutter hub 11 is string configuration, sets the block structure of strip, is used convenient for long-term polishing, further improves use
Service life.
The knife bottom 12 of 11 bottom side of cutter hub is a plane, its bottom is set as plane, convenient for it being fixed installation.
The knife spine 13 at 11 top of cutter hub is also planar structure, top is set as planar structure during installation, just
In carry out positioning compacting or screens installation.
Knife bottom 12 is upwardly extended collectively constitutes solid cuboid column structure with knife spine 13, using solid construction, not only
Increase the stability of cutter hub 11, and formed the entirety of more conventional structure, be not only convenient for installation and manufacture easy to produce.
12 top end of knife bottom extends the point of a knife 14 formed with 13 top of knife spine for cutting cloth obliquely.Adequately profit
With point of a knife 14, adequately ensure its marginal position sharpness, to realize constantly cutting to cloth roll, it is to revolve that this, which cuts process,
It is gradually carried out during turning.
The point of a knife 14 is triangular prism shape structure, and the end of prism is sharp sword, the bottom of prism and the end pair of cuboid
It connects to form totality.Polishing can be carried out directed along the end of cuboid can form the oblique side in both sides of triangular prism.Not only
Ensure cutting property, and ensure a firm globality.
The top at knife bottom 12 upwardly extends the blade 15 being formed between point of a knife 14 for cutting cloth.By the side of prism
Edge is adequately polished, and is formed the blade 15 with cutting edge, is fully polished to form cut edge along marginal position using blade 15.
The front side of the point of a knife 14 is polished to form flat sword side 16, and sword side 16 tilts polishing and forms inclination from top to bottom
Sharp sword because structure with strip forms sword side 16, the edge of yardage roll is constantly cut by sword side 16.And then sword
The top that side 16 extends point of a knife 14 tilts down the another sharp sword to form cutting cloth.
16 bottom side of sword side is polished the crisperding 17 to be formed and be recessed in oriented point of a knife 14.During being cut on sword side 16,
In order to improve 16 bottom of sword side to cloth cut and cutting effect, setting cut edge with internal hook shape structure, accelerate to cut out
To the stability of cloth cutting during cutting.
The hook angle a for cutting is formed between the blade 15 of 14 downside of the crisperding 17 and point of a knife.In the process used
In, the effect that cuts to form height sets crisperding 17, for different clothes cut the setting of intensity,
The range for hooking angle a is in the range of 90 degree to 150 degree.Its intensity of cropped cloth is smaller, angle
Degree is set bigger, according to the difference for cutting intensity, is polished the angle that cuts for hooking angle a.
The number of degrees for hooking angle a are 120 degree, wherein, larger range can be applicable in by being set as 120 degree, replaced and cut out
The frequency of knife 100 is relatively low, and it is more to be applicable in the cloth cut.
Length relation is five times to ten times between the long m of knife of the cut-off knife 100 and the wide n of knife.To ensure the firm of cut-off knife 100
Property, during use, according to the difference of the strength of materials, ratio between the two is set, with cut-off knife during use
It bends.
The tail end of the knife spine 13 is equipped with a positioning port 131 to lower recess, it is carried out along the knife spine 13 of cut-off knife 100
Location and installation, for cut-off knife position is avoided to move, setting positioning port 131 carries out location and installation to it, it is ensured that while firm,
Ensure that cutting stablizing for position carries out.
The foregoing is merely embodiments herein, moreover, the title that parts are taken in the application can not also
Together, the title being not intended to limit in the application.To those skilled in the art, the application can have various modifications and variations.
All any modification, equivalent replacement, improvement and so within the design of the application and principle, should be included in the power of the application
Within sharp claimed range.
