Description
Technical field
The present invention relates to a kind of according to claim 1 as described in the preamble for manufacturing chopped fiber/cut staple
Fibre cutting machine.
Background technology
In order to manufacture chopped fiber, it is known that fibre cutting equipment, from the silk being made up of staple fibre in fibre cutting equipment
Beam is made short cut staple.The equipment or be configured to single-stage or be configured to two grades.The process of single-stage is comprising artificial
The melt-spun of fiber, merged into tow, the stretching of tow and further heat treatment.Additionally, if necessary in crimping machine
In make artificial fiber crimp.Finally, by tow cutting short-forming fiber in fibre cutting machine.During two grades, during this period
The staple fibre for being merged into fibre bundle is stored in storing kettle.In so-called fiberline, drawn from multiple storing kettles
Go out fibre bundle, tow is formed by the fibre bundle.In fiberline, carry out the further treatment of tow, its end by
The tow is cut off in fibre cutting machine.The chopped fiber being made for example can be used as the substitute of cotton fiber during follow-up.
Such fibre cutting machine is described in document DE3105877A1.In knife rest, multiple cutters are flatly
It is arranged to a circle.Blade for tow to be cut into chopped fiber is radially oriented herein.Ring is formed in the way of to abut blade
Shape passage, tow is directed in the way of multiple-turns wound in the circular passage.Circular passage passes through blade, knife rest and hold-down ring
Formed.Not only knife rest but also hold-down ring is pivotally supported by, wherein, knife rest can be rotated by means of drive shaft.
The pivot center of knife rest and hold-down ring is at an angle to each other herein, so that the height of circular passage persistently changes.In circular passage
Such region in tow is cut into chopped fiber, i.e. the height of circular passage is reduced to turning point always in this region,
Height increases again since it.In above-mentioned zone, towards the direction of blade be applied on tow a power by hold-down ring.Depending on product
Depending on product and other manufacturing parameters, described cutting zone extends in the about a quarter of the circumference of knife rest.Chopped fiber is at it
In the collection vessel being arranged under fibre cutting machine being fallen after cutting due to gravity.Each cutter is by its blade and two
The flank of tool is constituted, and when fibre cutting machine works, is slided along the flank of tool after its cut-out by the chopped fiber that blade cuts out
It is dynamic.Thus, the pressure being applied on cutter perpendicular to the flank of tool and the frictional force stretched parallel to the flank of tool are produced.Institute
To act the pressure on the flank of tool, because the flank of tool is parallel to knife rest axes orientation and thus relative to logical
Crossing the power that hold-down ring is applied on tow has angle.In limiting case, the angle is corresponding to knife rest axis and compression annulate shaft
Angle between line.On the minimum point of the height of circular passage, the pressure being applied on cutter is almost nil, because
Here the power for being applied on tow by hold-down ring and being therefore applied on the flank of tool stretches parallel to the flank of tool.It is known at this
Occur in the device, pressure that is applied on cutter is generally very high, and this causes the opposite with its direct of travel tight of cutter
Bend again.Thus, the risk of cracking of cutter is very high.There is the use of intensity high in terms of bend loading accordingly by selection
Can overcome this cracking of cutter in the material of cutter.However, this material is not suitable for use in cutting tool because its have it is low
Hardness is so as to blade Fast Wearing.The blade of so abrasion causes fitly to cut.
The content of the invention
Thus it is an object of the invention to provide such fibre cutting machine, wherein avoid the occurrence of cracking of cutter and
However but fibre cutting machine also have performance and cutting power high.
According to the present invention, the target pass through make between the flank of tool and knife rest axis of cutter formed tool angle in
At least one realizes between 2 ° to 15 °.By this way, the minimum pressure being applied on the flank of tool is made.
The present invention is also different from the device shown in document DE3506282A1.Show there for cutting banding
Although or strip article device it is equally tilting with cutter, the also other basic arrangement knot with cutter
Structure, thus enforceable cutting process is entirely different.Here, cutter is arranged vertically, thus blade parallel to and be not orthogonal to knife
Frame axis stretches.In this cutters layout structure, tow multiple-turns wound cutter itself, rather than such as in fibre of the invention
Knife rest is wound in dimension cutting machine like that.Except the power being applied to by tow separately through the winding on blade, additionally by
Pressure is applied on tow towards the direction of blade in contact roller.With the apparatus according to the invention on the contrary, the power only exists
It is applied on tow on a little and is applied in larger angular regions rather than as in the case of when using hold-down ring
On tow.To be similar to point-like power be applied on tow caused on direct of travel before contact roller to be produced from tow it is grand
Rise.In cutting, the protuberance is eliminated again, wherein, extruding work is completed in tow itself.Due to the extrusion process, compress
The power of wheel is redirect on the direction opposite with the direct of travel of cutter.In fibre cutting machine of the invention, this is not formed
Plant protuberance.Thus, the cutting force in two kinds of devices sets up entirely different, therefore two kinds of devices are comparable.
In fibre cutting machine of the invention, the cutting of tow is carried out in the following manner, i.e. by means of inclined
Be pressed onto tow on blade by hold-down ring.Described above, by means of the tilting of cutting tool according to the present invention side, it is applied to knife
Have the pressure on side and thus the bend loading of cutter is minimized.At this point it is noted that in cutting process
The bend loading of period cutter is change.In order to show the phenomenon, refer to the attached drawing and its description exactly.It is curved except cutter
Outside bent load, because its is tilting, the friction between chopped fiber and the flank of tool also reduces, thus need less energy be used for into
Row cutting.The bend loading of reduction brings lot of advantages and many optimization fibre cutting machines and its possibility of work.For example, with
Fibre cutting machine with the flank of tool arranged parallel to knife rest axis is compared, and output is significantly improved, without losing short fibre
Dimension quality, or improve cracking of cutter quantity.Additionally, the tieing that may be present in tow will not immediately result in cracking of cutter.
On the other hand, when identical output is completed by fibre cutting machine, compared with the cutter arranged parallel to knife rest axis, often
It is weaker that individual tilting cutter is all embodied as stability.So, cutter is embodied as thinner, that is to say, that with each other
Closer to the flank of tool, so as to further reduce friction of the chopped fiber at the flank of tool.
In preferred form of implementation of the invention, compressing the subtended angle formed between ring axis and knife rest axis at 4 ° and
In scope between 15 °.Thus, the optimal cutting force between tow and blade can be produced.Tow is being not necessarily this consumption
Chopped fiber is reliably cut into the case of excessive power.According to that what kind of tow should be cut into what kind of final product, slightly
Micromodification becomes optimal angle.Here, not only the single fiber number of the single long filament of the total fiber number of tow but also tow has important work
With.Additionally, the polymer for being made from it tow is also critically important.The desired characteristic of final products, the length of such as chopped fiber
Play an important role.
Preferably, tool angle opens on the contrary with cutter direct of travel.During cutting, power and the cutter of hold-down ring are advanced
Act in the opposite direction.In order to reduce the bend loading being applied on the flank of tool, the flank of tool must be located at as far as possible with by
On the force vector identical direction that hold-down ring is applied on the flank of tool by tow.So, when the flank of tool and force vector that
When this is parallel, in the absence of bend loading.
In preferred form of implementation of the invention, all cutters all have identical tool angle.In this fibre cutting
When machine works, the chopped fiber of phase homogenous quantities is produced.Here, the characteristic variations very little of single chopped fiber.
Advantageously, two flank of tools of same cutter are parallel to each other.This cutter can simply and therefore cost advantages
Ground manufacture.Additionally, this cutter can form identical and constant width cutting channel.It means that in two adjacent knives
The distance between two relative flank of tools of tool are constant.Reduction of the distance on the direct of travel of chopped fiber can cause
Frictional force between chopped fiber and the flank of tool is improved, and this should be avoided by.
In another form of implementation of fibre cutting machine of the invention, two flank of tools of same cutter are relative
At an angle to each other.When the angle between the flank of tool reduces on the direct of travel of chopped fiber, can further reduce and be applied to
Bend loading on cutter, this is further exaggerated advantage already described above.
In preferred form of implementation of the invention, cutter is made up of hard metal.Hard metal is especially suitable for use as cutting
Instrument is cut, because its extremely abrasive damage.So, in the working time very long blade also keep it is sharp and can fitly by
Tow cuts into chopped fiber.Although hard metal only has relatively low bending strength, due to cutting tool according to the present invention
Arrangement, its even no longer must as in the case of in the known fibre cutting machine with hold-down ring height.
By means of device characteristic illustrated above, manufacture there can be extraordinary property in the case where cracking of cutter is minimized
The high-quality chopped fiber of energy.

On force vector may be logically divided into two components, one perpendicular to the component of the flank of tool and one parallel to the flank of tool 11 point
Amount.Vertical component causes the bending of cutter, and cutter must have corresponding bending strength high.Parallel force component is used to overcome
Friction between chopped fiber and the flank of tool 11.In order that the bend loading in being applied to cutter 9 is by whole
Integration during individual cutting zone 23 is minimized, and cutter 9 is inclined a tool angle 17.Tool angle 17 two flank of tools 11 with
Produced between knife rest axis 7.Tool angle 17 opens on the contrary with the direct of travel of cutter 9, so as to make at cutting beginning portion 21
The vertical force component used on cutter 9 is smaller.It is reasonably, all values with identical tool angle 17 of all cutters 9.It is preferred that
Ground, subtended angle 16 is between 4 ° and 15 °.In order to realize optimal cutting, depending on the characteristic of tow 1 and chopped fiber to be generated,
Subtended angle 16 is changed.Corresponding tool angle 17 is between 2 ° and 15 °.Thus, the bend loading being applied on cutter can be reduced.Such as
Fruit subtended angle 16 and tool angle 17 are all 15 °, then bend loading before cutting end portion 22 at 90 ° of cutting beginning portion 21 etc.
In zero.In order that the integration of the bend loading being applied on cutter is minimized, tool angle 17 be preferably 0 ° and subtended angle 16 it
Between average value or median.In so selection tool angle 17, acted on the flank of tool 11 at cutting beginning portion 21
Force vector is observed positioned at the front end of cutter 9 in rotation direction.At this point, maximum power is made on the contrary with rotation direction
Use on cutter 9.Power in the perpendicular acting to cutter 9 reduces in ensuing cutting process, until it locates to reach on one point
To null value.The point is nearly seated at the center of cutting zone 23.Here, force vector is just parallel to two flank of tools 11.From
In the cutting process of the continuation that the center is lighted, force vector is applied to the observation in rotation direction and is located on the rear side of cutter 9
On the flank of tool 11.The vertical component of the power being applied on the flank of tool 11 increases, until cutting end portion, reaches it in this place
Maximum.Thus, cutter 9 is bent loading and in the second cutting section on the contrary in the first cutting section with rotation direction
In loading is bent in rotation direction.Thus, generally speaking, with the flank of tool 11 parallel to knife rest axis 7 the phase of cutter 9
Than, hence it is evident that reduce the integrally bending load on whole cutting zone 23.Additionally, except the bend loading being applied on cutter
Reduce up to 50%, also reduce the friction load being applied on cutter, so as to reach identical cutting power, it is only necessary to by pressing
Be applied to smaller power on blade 10 by tight ring 12.
