The specific embodiment
Fig. 1 among all figure shows a device 1 that is used to form continuous cigarette rods 2, and its constitutes the part of cigarette-making machine.
Like this one device 1 comprises a conveyer 3, by this conveyer to a Continuous Flow 4 that forms the entry position 5 feeding tobacco particles of station 6, to produce the continuous cigarette rods 2 that advances to the direction 7 of being scheduled to along predetermined path 8.Forming station 6 is traditional embodiment, thereby no longer it is further described.
The form of preferably a kind of air-breathing belt 9 of conveyer 3, described air-breathing belt be looped around in the each end (the one end only is shown among Fig. 1) can around be parallel to each other and the axial rotation roller 10 of level on.Air-breathing belt 9 forms the ring of a closure of surrounding chamber 11, and this chamber 11 is connected to negative pressure source (not shown) by means of relevant pipeline 12, and is delimited by the wall 13 that penetrates SS 14 at the place, bottom.
The bottom branch 15 of conveyer 9 and the operation of wall 13 sliding-contacts ground, and can be when occurring at the vertical rising head pipeline 16 (among Fig. 1, only showing left part) of fibrous tobacco particle P under being arranged on bottom branch 15, by suction they are maintained, so that tobacco particle forms Continuous Flow 4.
Device 1 is in the running of 5 places, entry position of the station 6 that forms continuous cigarette rods 2, and it comprises the conveyer 7 of one one-tenth ring, and its branch extends under the bottom of air-breathing belt 9 branch 15, and occupies a zone of converging with this belt 9.
The conveyer 17 of embarking on journey passes through around roller 18 (figure 1 illustrates one of them), and comprises that a top branch 19, this top branch be arranged to and be used for support a workbench 20 sliding-contacts from the band of rolling up the cigarette paper 21 that unwinding is got off on 22.
Air-breathing belt 9 is discharged into tobacco core material stream 4 on the band of paper 21, and with its carrier band to forming in the station 6, form in station at this, with this identical paper 21 described tobacco core material is sealed.
For being prepares tobacco core material stream 4 with its subsequent step that is encapsulated in the paper 21, and form the predetermined portions C (referring to Fig. 4 b to 4d) of closely knit combination, flow out in order to prevent core material cutting tip from single cigarette in the subsequent step of manufacture process.Therefore, device 1 comprises: be installed on stream 4 predefined paths of being followed 8 and at one first clipping device 23 that forms station 6 early-stage works, in first clipping device, the 23 downstreams work of relative direction of feed 7 and be used for making the closely knit device 24 of the tobacco core material part consistent with aforementioned portion C, and one second clipping device 25 of working in the downstream of compacting apparatus 24.
The compacting apparatus 24 and second clipping device 25 are traditional types.In an example shown, compacting apparatus 24 is cam-operated force-applying member (each production line is provided with), and second clipping device 25 comprises the circular shear blade of a pair of reverse rotation.
Under first trimming device 23 and second trimming device 25 cell therefor is set in a conventional manner, schematically indicates to be denoted as 26 square, these containers are arranged to collect the broken tobacco that cut operation removes.By traditional retracting device (not shown), callable broken tobacco is drawn back cycle of treatment.
Shown in Fig. 2,3 and 4, first clipping device 23 is used for reducing flowing 4 thickness in the presumptive area corresponding to aforementioned predetermined closely knit portion C, therefore synchronous with compacting apparatus 24 in running.
Compacting apparatus 24 and first is pruned mechanism 23 and is synchronously worked with a cutter (not shown) of similar type, described cutter setting is arranged on the downstream that forms station 6, and periodically continuous cigarette rods is divided into singlely, and make dense region consistent with all cutting tip.
More precisely, and see also Fig. 4 a, 4b, 4c and 4d, because the thickness of the stream 4 that transports out from rising head pipeline 16 is irregular and is uneven profile (intentionally having emphasized this point among Fig. 4 a), therefore, only carry out first shearing procedure (Fig. 4 b) along the predetermined portions C that is predefined for the effect that stands compacting apparatus 24, the thickness that makes these described portion C so evenly is a predetermined value S1 (Fig. 4 c).
After compression step, carry out one second shearing procedure (Fig. 4 d) along the whole length convection current 4 of stream, form a preset thickness that is denoted as S2 like this.
By this way, just only pruned once, consequently obviously reduced the degree of deterioration of final tobacco quality without undergoing the part N of the effect of compacting apparatus 24.
Referring to Fig. 2 and 3, first clipping device 23 that is designed to carry out first shearing procedure comprises a rotating knife 27, and this rotating knife separates a distance that equates with the first thickness S1 with the bottom branch 15 of air-breathing belt 9.
Or rather, rotating knife 27 comprises the disk 28 that at least one blade 30 is housed, and described blade radially stretches out from the periphery 29 of disk 28.
As shown in Figure 2, disk 28 only has a blade 30, and this blade is the circular arc with the concentric circle of disk.The radius of the quantity of the single blade 30 that disk 28 is had, angular distance that each blade 30 is surrounded on the edge 29 of disk 28 and blade 30 is the design parameters that can change according to the specification of the characteristic of the cigarette of being produced or machine, and does not influence protection scope of the present invention.
When rotating knife 27 was in position with flow of tobacco 4 interferences, blade 30 brushes were against a location or a ram 31, and described ram 31 is by being arranged to transverse to disk plane, 28 place and being parallel to stream 4 and the wall 32 that extends constitutes.For favourable, this ram 31 can also move back and forth along the direction that is parallel to the predetermined direction of feed 7 that flow of tobacco 4 followed, and synchronous with rotating knife 27, to avoid the sliding-contact with the motion of blade 30 by the motion of accompanying blade 30.
In fact, when blade 30 skimmed over flow of tobacco 4, ram 31 was along identical direction V1 and with the speed displacement identical with blade 30.Then, when blade 30 is finished complete once circulation and when interference position is rotated, ram 31 will be along opposite direction V2 displacement, to arrive its starting position (Fig. 2) again.
Shown in preferred embodiment in, flow of tobacco 4 advances along a limiting groove 34, described limiting groove is created between the sidewall that is denoted as 33a and 33b.When cutter 27 was in interference position, blade 30 played the effect of an enclosed slot 34.
To become and be apparent that, the present invention has overcome the shortcoming relevant with prior art, and as described and shown in first clipping device 23 in realized pointed purpose, this first clipping device 23 circulates and synchronously works with compacting apparatus 24, thereby has reduced the thickness of flow of tobacco 4 in the selected location consistent with aforesaid predetermined closely knit portion C.
The method according to this invention and device are having positive role aspect the quality of improving the recovery tobacco.
In fact, to stand two parts of pruning action only be the portion C that is compacted to tobacco core material stream 4.
Thereby can reach a conclusion, the average-size that reclaims tobacco particle will be bigger than the particle that constitutes the chip that two shearing procedures in succession remove.
If the average-size of described particle increases, then the filling capacity of tobacco compared with prior art is improved, and final cigarette will have, and more uniform tobacco core material distributes from the end to the end.
At last, overall bigger recovery tobacco particle is in follow-up processing operation or will combine more securely with fibrous material when the smoker handles, and can easily not be scattered from the end of cigarette.
Have two cigarette rods and form Fig. 2 of cigarette-making machine of production lines and Fig. 3 and can see second tobacco core material stream 4, second groove 34 and second cutter 23 shown in broken lines from relating to.
