Description
Technical field
The present invention relates to a kind of cutting head in tobacco product production machine, that be used at least one continuous bar.
More specifically, cutting head according to the present invention can be applied to cut the production of cigarettes machine of at least one continuous cigarette rods valuably, or is applied to cut the cigarette filter production machine of at least one continuous filtration mouth bar.
More specifically, cutting head according to the present invention can be applied to produce the two-wire machine of cigarette product valuably, that is to say, machine is axially characterized with the parallel mode of advancing of mouth through two continuous bars side by side.
Background technology
The cutting head of prior art comprises cylinder, and this cylinder is limited two circular sidewalls and turning circle cylindrical wall, and this cylindrical wall is connected to each other two sidewalls to form obturator.Said cylinder is around corresponding rotation rotation and on its side, carry two opposite cutter hubs, and these two opposite cutter hubs protrude in same turret wall.
Specifically, cutter hub is assemblied in the corresponding cutter hub fixator that connects cylinder.Cutter hub fixator and corresponding cutter hub can rotate around corresponding rotation with respect to cylinder, this axis be radially and perpendicular to the axis of cylinder rotation.
Thereby cutting head connects corresponding counter blade equipment forms cutter unit.Counter blade equipment generally includes the rotating circular disk conveyer belt, and it has installation a plurality of cutter hub guide bushings within it, thereby lining circulation contact respective rods keeps it horizontal, thereby each cutter hub guide bushing provides the cutter hub can be through the central channel that cuts.In other words, when cutter hub through the time in order to stop bar to rock and to vibrate, each bar is kept laterally by lining.
Because continuously bar is advanced at a predetermined velocity and cut and must carry out continuously and vertical with direct of travel, each must follow bar to advance with the speed of bar gait of march coordination by this way near cutter hub of being cut bar.
In this, in the cutting head of prior art, cylinder leads as follows: the rotation of cylinder produces predetermined α angle with respect to the direct of travel of bar.Therefore said α angle determines the scope of velocity component, and this velocity component is parallel to the speed of bar and therefore strictly gets in touch with cigarette that will cut or filter-tip size.In this; Must should be mentioned that give in the process of cutter hub guide bushing motion at carousel, each cutter hub guide bushing rotates with such a speed; This speed has the component that equals the bar gait of march, so modulate through the cutter hub passage of groove intactly.
In addition, must should be mentioned that continuous bar must be cut with direct of travel with meeting at right angles.For this purpose, each cutter hub is directed with respect to cylinder by this way, at least when cutter hub and bar near the time and the direct of travel of bar meet at right angles.
The device of adjusting the angle position of cutter hub was positioned in the cylinder and operated cutter hub by this way being used to of being fit to: keep cutter hub and bar direct of travel meet at right angles one when cutter hub be positioned at bar place one or even changing to kinds of cigarettes or the filter tip size after.
In other words, when the length of indivedual cigarette sticks or filter tip bung need change, it was necessary changing the α angle that is formed between cylinder rotation and the continuous bar direct of travel.This is to accomplish through the inclination angle that changes cylinder.Therefore adjusting device above-mentioned operates cutter hub as follows: when cutter hub arrived continuous bar, cutter hub was perpendicular to the bar direct of travel.
In the cutting head of prior art, to give an example, adjusting device is included in the universal drive shaft of operating between cylinder installation shaft and the cutter hub fixator.
Therefore, each cutter hub fixator is two rotation swings that limit between the position around each cutter hub fixator, and therefore when each cutter hub fixator passes through continuous bar, each cutter hub fixator roughly meets at right angles with the direct of travel of continuous bar.
Yet the advantage at the α angle that cylinder tilts is not considered in this correction; Cutter hub only accurately meets at right angles at a cutting position and bar; And near this position; The cutter hub slight inclination, this be since around cutter hub fixator rotation around longitudinal axis wave, and owing to wind rotation with the oblique axis cylinder of α angle lapping.
Therefore, unfriendly, when each cutter hub during through corresponding cutter hub guide bushing because cutter hub waves in the circle that limits, cutter hub with meet at right angles to bar direct of travel inaccuracy continuously.In other words, in continuous bar cutting process, cutter hub waves around their rotating shaft with corresponding cutter hub fixator.
This has two main shortcomings at least.At first, therefore, the cigarette sticks or the filter tip bung that obtain are not with accurate right angle cuts.
Secondly, in cutting process, cutter hub not necessarily contacts the cutter hub guide bushing, yet, slightly contact with the cutter hub guide bushing.More particularly, this contact more similarly is to occur in that cutter hub gets into and when withdrawing from the slit of cutter hub guide bushing.Except infringement cutter hub and/or lining, this contact causes that cutter hub shakes.This shakes and causes further mistake and the inaccuracy in continuous bar cutting process.
In addition, must should be mentioned that also in the cutting head of prior art that it is impossible adopting more than two cutting heads.In fact, if adopted more a plurality of cutting heads, can increase the coarse risk of cutting and cutter hub breakage to unacceptable degree by shaking of causing of normally used adjusting device.
The feeding equipment has also been assembled in cutting head above-mentioned inside, and the constantly outside feeding cutter hub of feeding equipment compensates the wearing and tearing of cutter hub in the use.These feedings equipment is inserted cutting head and relative complex usually, and their shared spaces make installation 180 ° the unusual difficulty of two cutter hubs each other.Further, just in time because they are placed in the cutting head, they are difficult to regular maintenance.
Summary of the invention
In this article, basic fundamental target of the present invention provides a kind of cutting head in tobacco product production machine, that be used at least one continuous bar, and it has overcome the shortcoming of prior art above-mentioned.
More particularly, purpose of the present invention provides a kind ofly produces cutting head in the machine, that be used at least one continuous bar at tobacco product, lasting precision when it can guarantee to cut at least one continuous bar.
Another object of the present invention is to overcome the cutter hub wear problems to avoid frequent daily and additional maintenance simultaneously.
Pointed technical goal and listed purpose through a kind of tobacco product produce in the machine, be used at least one.The cutting head of individual continuous bar comes basic realization, and it comprises the technical characterictic of stating in corresponding one or more claim.

The specific embodiment
With reference to accompanying drawing, numeral 1 integrally is illustrated in tobacco product and produces cutting head in the machine, that be used at least one continuous bar.
Cutting head 1 is positioned at the downstream of the unit (not shown) that is used to produce at least one continuous bar 2.
Particularly, cutting head 1 is positioned at the downstream of unit of downstream or the production continuous filtration mouth bar 2 of the unit that produces continuous cigarette rods 2.
Preferably, described cutting head 1 is positioned at the downstream of the unit that produces a pair of continuous bar 2, and these continuous bars 2 are placed to parallel and advance at equidirectional along common feeding axis " D ".Therefore, cutting head 1 preferably is applied to the two-wire machine.
Therefore, when cutter hub 4 rotation and when extending to the continuous bar 2 that will cut, each bar 2 self is under roughly the same condition.See that from more details cutting head 1 comprises a plurality of cutter hubs 4, these cutter hub 4 peripheries are connected to supporter 3 and the equal angular separation that separates each other, ground preferably, and cutting head 1 comprises 4 cutter hubs 4.
As shown in the figure, supporter 3 comprises two cross part 5a, 5b, and they are structurally separated from one another but interrelated, and they each all around corresponding rotation A1, A2 rotation.
At length, the 5a of first connects motor (accompanying drawing is not shown) as follows: rotate and more particularly rotate around pivot R1 around rotation A1.
The rotation A1 of the 5a of first produces the α angle with the feeding axis " D " of continuous bar 2, and this angle becomes according to cigarette to be cut or filter-tip size.
In fact, a velocity component of α angle decision cutter hub 4, the feeding axis " D " and the direct of travel of this velocity component and bar 2 is consistent in rotary course.
Related with the 5a of first as stated second portion 5b more particularly drives around pivot R2 rotation and by the 5a of first around rotation A2 rotation, and it is obvious to become in the explanation hereinafter.
At length, second portion 5b is connected to back shaft 14 restrictions of second portion 5b at its rotation A2 place.
Must should be mentioned that, the part 5a of supporter 3,5b side by side and the skew.In other words, the rotation A1 of part 5a, 5b, A2 is always parallel but separate.Must should be mentioned that also the pivot R1 of part 5a, 5b, R2 are positioned on the straight line that is parallel to feeding axis " D ".
In order to change to cigarette to be cut or filter-tip different size, the α angle must change with the variation of the inclination of the 5a of first.Therefore the inclination of second portion 5b correspondingly changes as follows: rotation A1, A2 keeping parallelism.Further, follow this operation, feeding axis " D " keeping parallelism of the pivot R1 of coupling part 5a, 5b, the straight line of R2 and continuous bar 2.
According to the present invention, each linkage unit 6 comprises fixture 7,8, and this fixture 7,8 is used for fixing the position on plane, corresponding cutter hub 4 place.More specifically, in the process that cutter hub 4 and supporter 3 rotate about rotation A1, A2 as one, this fixture 7,8 keeps the planes, cutter hub 4 place and the feeding axis " D " of continuous bar to meet at right angles consistently.
The preferred embodiment of concrete referenced in schematic, fixture 7,8 (there is more details definition the back and describes) is four bar linkage types.More particularly, thus each linkage unit 6 cooperates with part 5a, the 5b of supporter 3 and forms four bar linkages.Therefore, cutter hub plane, 4 place and continuously the formed angle in interval between the feeding axis " D " of bar 2 in the rotary course of the rotation A1 of supporter 3, A2, keep constant at cutter hub 4.
More particularly, each linkage unit 6 comprises the corresponding cutter hub fixator 7 that carries corresponding cutter hub 4.
More specifically, therefore each cutter hub fixator 7 is connected to supporter 3 at the outer rim 3a of supporter 3, so that this cutter hub fixator 7 self rotates with respect to supporter 3.In other words, each cutter hub fixator 7 connects part 5a, the 5b of supporter 3 rotatably.
In this, each linkage unit 6 comprises the pair of pin 8 related with each cutter hub fixator 7.Especially, the pin of each in the said pair of pin 8 is connected to corresponding cutter hub fixator 7 5a of first and the second portion 5b of supporter 3 separately.
Along with the propelling of describing will be clearer, the corresponding cutter hub fixator 7 that pin 8 allows to be associated with it is around the first rotation B1, B2 and the second rotation E1, E2 rotation.The first rotation B1, B2 and the second rotation E1, E2 are vertical.
As shown in the figure; Each pin 8 comprises the first tube-like piece 9a and the second tube-like piece 9b; This first tube-like piece 9a defines the first rotation B1, B2 and rotatably inserts cutter hub fixator 7, and this second tube-like piece 9b defines the second rotation E1, E2 and rotatably inserts the 5a of first or the second portion 5b of supporter 3.
The first tube-like piece 9a and the second tube-like piece 9b are connected to each other to whole and meet at right angles each other.
Particularly, the first tube-like piece 9a is contained in the corresponding connection lining 10 of cutter hub fixator 7, and the second tube-like piece 9b is contained in by in the part 5a of supporter 3, the radial hole 11 that 5b forms.
Therefore, through cutter hub fixator 7, each linkage unit 6 supports corresponding cutter hub 4, and this cutter hub 4 is both around rotating with axis A1, the rectangular said rotation E1 of A2, E2, also around rotating with rotation E1, the rectangular said rotating shaft B1 of E2, B2.
In an illustrated embodiment, each pin 8 is T shapes roughly.Yet in unshowned alternate embodiment, pin 8 can have any other shape, gives an example, and such as L shaped or cross, thereby defines the first rotation B1, B2 and the second rotation E1, the E2 that is perpendicular to one another.
Therefore, each cutter hub fixator 7 rotates with respect to part 5a, 5b by this way, keeps and the pivot R1 of the part 5a that is connected supporter 3,5b, the straight line parallel of R2.
More details; Shown in accompanying drawing 3; Here C1 representes the intersection point between an E1 and the B1; C2 representes the intersection point between an E2 and the B2, and cutter hub 4 is installed in the cutter hub fixator 7 as follows: the part 4a that works of cutter hub 4 meets at right angles with the straight line that is connected center C 1 and C2, and whenever the line that connects center C 1 and C2 in use all keeps and the line parallel that is connected center R1 and R2.
In other words, the second rotating shaft E1 that radially is provided with around part 5a, 5b of each cutter hub fixator 7, E2 rotation along supporter 3.The second rotating shaft E1, E2 and the first rotating shaft B1, B2 are vertical, and also rotating shaft A1, the A2 with part 5a, 5b is vertical, and the second rotating shaft E1, E2 are through part 5a, the pivot R1 of 5b, R2.
Of specification, said fixture 7,8 is the cutter hub fixator 7 that is bonded to each other and sell 8 and limit.
Next, significantly, fixture 7,8 is limited linkage unit 6.
As already mentioned, the linkage unit 6 of cutter hub 4 and part 5a, the 5b of supporter 3 define four bar linkages.
In other words, the 5a of first of supporter 3 and second portion 5b define the corresponding crank of four bar linkages, and cutter hub fixator 7 defines the respective link that is connected to crank.
Like accompanying drawing 3, clearly the rotation A1 of four bar linkages and A2 do not meet at right angles with plane, crank place.Therefore link motion is not plane motion, and spatially extends.
Allow cutter hub fixator 7 to rotate around the first rotation B1, B2 about pin 8, the first tube-like piece 9a, and the second tube-like piece 9b allow cutter hub fixator 7 to rotate around the second rotating shaft E1, E2 with respect to part 5a, 5b with respect to part 5a, 5b.
On the other hand, cutter hub fixator 7 comprises the shell wall 12 that is used for cutter hub 4, and cutter hub 4 stops and is fixed on the said shell wall.
In other words, the plane 13a on surface 13 is arranged at the rectangular position of feeding axis " D " with continuous bar 2, and supports the part 4a that works of cutter hub 4.
Advantageously, curved surface 13 is taken in the storage compartment of cutter hub 4, and when working part 4a wearing and tearing and constantly during aggravation, this storage compartment is used to replace the part of the part 4a that works of cutter hub 4.As shown in Figure 3, the storage compartment 4b of cutter hub 4 is attached to the curved surface 13 that holds it.
Cutting head 1 according to the present invention is connected with counter blade equipment (not shown in the accompanying drawing) so that form the cutter unit that tobacco product is produced machine.
Counter blade equipment comprises the rotating circular disk conveyer belt that a plurality of cutter hub guiding pieces are installed.When the cutter hub guiding piece rotated, they moved towards corresponding bar continuously, in bar is completely contained in lining.
Each lining comprises corresponding groove, this groove allow cutter hub through such mode through the cutter hub guide bushing, shake or vibrate to keep the clean bar that do not cause with cutting accurately.
Like Figure 11,12, shown in 13; About cutter hub 4 and its storage compartment 4b; Said linkage unit 6 comprises the motion 28 that promotes cutter hub 4 with cutter hub fixator 7, and its surface 13 along cutter hub 4 shell walls 12 promotes cutter hub 4, more particularly promotes the storage compartment 4b of cutter hub 4.
Next, motion 28 defines the recovery device 19 of the part 4a that works that is used to recover cutter hub 4.
More particularly, the end 30 that works is frustoconical, below with explanation reasons.
Second pin 31 is contained in the part 32 of the first tube-like piece 9a by this way: slide on the both direction shown in arrow F3, F24 along axis B2.Second pin 31 has first terminal 33 and second terminal 34, the first terminal 33 and faces outside terminal 30, the second terminal 34 protrusions, the first tube-like piece 9a that work of first pin 29.
More particularly, two ends 33 of second pin 31 be hemispherical with 34, understand explanation below the reason.
Like Fig. 1,2, shown in 4, lever 35 is hinged on the top 36 of cutter hub fixator 7.
More particularly, lever 35 is around vibrating the flat part 36a that axis X is articulated in top 36, shown in Figure 11 and 13.
The free end 37 of lever 35 contacts with second terminal 34 of second pin 31.
At the pin joint place, lever 35 is bonded to screw 38, and this screw 38 extends in the top 36 along axis D1, this axis D1 and axis X consistent and perpendicular to first and second the pin 29,31.
Shown in figure 13, axis normal at one end has the dentation profile 39a that meshes with screw 38 in the axle 39 of axis D1.
Shown in figure 12, the other end of axle 39 is through idle pulley 39b, and mesh as follows with axle 39 coaxial supply rolls 40: the idle pulley 39b of insertion allows supply roll 40 only to rotate in a direction, will introduce more details below.
The outer surface of cylinder 40 contacts with cutter hub 4.Cylinder 40 each quoted cutter hub 4 along with lever 35 around rotation X swing and the predetermined stroke of advancing, shown in arrow F5.
Obviously, the predetermined stroke that cutter hub 4 advances is the function of the radial dimension of dentation profile 39a and cylinder 40, thereby when cutter hub 4 wearing and tearing and lasting aggravation, cutter hub 4 is moved to recover the part 4a that works of cutter hub 4 along shell wall 12.
In use, in the preset time interval and according to the wearing and tearing on the cutter hub 4, compressed air source 41 transmits into a series of air pulsings in the second tube-like piece 9b.
Air pulsing moves first pin 29 along axis E 2 on arrow F1 direction.Because the shape of frustoconical, the end 30 that works of first pin 29 little by little meshes first end 33 of second pin 31 and knocking of stipulating.
As a result, second pin is 29 along axis B2 translation one stroke on arrow F3 direction, and the trip is limited knocking of giving of first pin 31.
Because second terminal 34 of second pin 31 contacts with the free end 37 of lever 35, second sells 31 mobile levers 35 that cause on the F3 direction is rotated counterclockwise (shown in figure 11).
The rotation of lever 35 is corresponding with the rotation around axis X of the screw 38 that is engaged in dentation profile 39a, thereby causes that axle 39 rotates.
When air pulsing stopped, first pin 29 turned back to the idle structure of first pin 29 in arrow F2 direction translation along axis E 2.Pin 29 can be through elasticity or pneumatic bias unit realization towards the translation of returning of its idle structure.
Valuably, motion 28 uses linkage unit 6 to process, and it keeps the structure of cutting head 1 and does not increase overall dimension.
The end 30 that works of first pin 29 is thrown off first end 33 of second pin 31 gradually, breaks away from first pin 29 fully up to second pin 31.
The rotation of lever 35 is corresponding with the rotation around axis X of the screw 38 that is engaged in dentation profile 39a, thereby causes that axle 39 ground rotate.
In this case, the reverse rotation of lever 35 also can realize through elasticity or pneumatic bias unit.
Valuably, since motion 28 is contained in the linkage unit 6, the size that this can not influence cutting head 1 is easy to carry out daily and extra maintenance.
The present invention has realized above-mentioned purpose, both has been the orientation of cutting head and counter blade unit, also is the recovery of cutting head self.
In fact, as stated, cutter hub jockey and supporter define four bar linkages.
Each cutter hub fixator 7 can be around axle B1 with each cutter hub 4 that therefore is fixed to it rigidly, and the B2 rotation is so that balance derives from the inclination at α angle.
For complete 360 ° of rotations, cutter hub fixator 7 remains parallel to self and the line that is connected center R1 and R2, and this line parallel is in the feeding axis D of bar.
Like this, in cutter hub and supporter one rotary course, whenever cutter hub self all is arranged in a plane, and this plane never changes its orientation with respect to the feeding axis of continuous bar.Obviously, this means that the cut edge and the feeding axis that are applied to continuous bar accurately meet at right angles.
In addition, because the cutter hub nonoscillatory, cutter hub can pass the lining of counter blade equipment, and the risk that does not contact with lining self.
In other words, this has prevented the infringement of cutter hub and/or cutter hub guide bushing and has obtained clean and accurate cutting.
In addition, cutting head of the present invention generally can comprise N cutter hub, and N equals 1 or greater than 1 integer here.
In the embodiment shown in accompanying drawing 5 and 6; The first tube-like piece 9a of the lateral part of qualification T shape pin 8 is patchhole 14 rotatably; This hole 14 is formed at the roughly end of radial arm 15; In two parts with respect to each part 5a, 5b, this arm 15 defines the space 16 that is used to admit cutter hub fixator 7.
Each part 9b that qualification T shape is sold 8 longitudinal components then rotatably is contained in the basic radial hole 17 that is formed at the respective bush that is connected to cutter hub fixator 7.
Clearly illustrate that among this second embodiment that the linkage function of two part 9a and 9b that forms T shape pin 8 is opposite with first embodiment.

Further, each clamp forks 8a comprises the corresponding second tube-like piece 9b, and the second tube-like piece 9b limits the second rotation E1, E2 and rotatably insert the 5a of first or the second portion 5b of supporter 3.
At length, the first tube-like piece 9a is contained among the corresponding connection lining 10a of clamp forks 8a, and the second tube-like piece 9b is contained in each the part 5a that is formed at supporter 3, in the radial hole 11 of 5b.
Therefore, each linkage unit 6 supports corresponding cutter hub 4 through box-like body 18, make cutter hub 4 both can around with axis A1, the rectangular said rotation E1 of A2, the E2 rotation, again can around with rotation E1, the rectangular said rotation B1 of E2, B2 rotation.
Therefore, each box-like body 18 is with respect to part 5a, and the 5b rotation is to remain parallel to the part 5a that connects supporter 3, the pivot R1 of 5b, the straight line of R2.
Further, shown in figure 10, at least the first tube-like piece 9a comprises pipeline 26 in inside, and 26 in pipeline comprises inlet 26a and outlet 26b, can describe their function below in more detail.
