Description

Self-sealing smoke generation section with isolating sheet and particle type cigarette

Technical Field

The utility model belongs to the technical field of heating cigarettes, and particularly relates to a self-blocking smoking section with a spacer and a particle type cigarette.

Background

Particle type cigarette props up is a neotype heating type cigarette in recent years, and it replaces tobacco sheet as smoking material with the granule of fuming, and the granule of fuming is heated more evenly than the tobacco sheet, and smog is also more smooth and easy than tobacco sheet class HNB cigarette along the interparticle clearance diffusion, consequently is liked by the consumer deeply.

The particle cigarette is formed by filling smoking particles into a paper cylinder with a sealed far lip end to form a particle section, and arranging a porous fixing part section (or a gear part), a cooling section (which can be a cavity section with holes or a cavity section filled with cooling materials) and a filtering section at the downstream of the particle section. Because the particles being smoked are loose and fluid, if unrestrained, they will flow into the downstream cavity section when the cigarette is placed horizontally, and these particles flowing downstream will not be heated effectively by the heater, and the smoking effect will be affected, so all particle-type cigarette structures at present are designed with the parts for restraining the particles being smoked from flowing around, wherein the upstream of the particles is usually restrained by the sealing film, and the downstream is restrained by the porous fastener section (or gear piece).

The porous fixing piece section material is usually ceramic or silica gel, and the center and/or the periphery of the porous fixing piece section material is provided with an axial through hole or a vent groove which can allow smoke particles to pass through but not allow the smoke particles to pass through, so that the smoke particles can be blocked and the smoke can be transmitted. In addition, when inserting resistance heating element or electromagnetism heating element and carrying out the central heating in the granule section, porous firmware section can also prevent the granule of being fuming from promoting porous firmware section itself and moving downstream under the propulsion of heating plate insertion force because of with fiber container inner wall interference fit. However, the presence of the porous anchoring portion increases the overall length of the cigarette, and it is therefore always desirable by those skilled in the art to simplify the structure of the porous anchoring portion and to reduce the volume of the porous anchoring portion.

The present invention has been made to solve the above problems.

Example 1

As shown in fig. 1, a first embodiment provides a self-sealing smoking segment I comprising: the smoke tube comprises a smoke tube 1, a front end spacer 3 arranged at the far lip end of the smoke tube 1, a rear end spacer 2 arranged at the near lip section end part (namely, the near lip end) of the smoke tube 1 and smoke particles 9 arranged between the front end spacer 3 and the rear end spacer 2. The smoke tube 1, the front end spacing block 3 and the rear end spacing block 2 are coaxially arranged.

As shown in fig. 2, the rear end spacer 2 has the following specific structure: the rear end spacer 2 is integrally a sheet-like member including: an annular frame 21 and a central diaphragm 22 bonded to the distal lip end side of the annular frame 21. The "distal lip end" is shown in the front view of fig. 2 as the back of the annular frame 21. The edge of the central membrane 22 near the lip end is an area covered by the annular frame 21, the center of the side is an area not covered by the annular frame 21, the area not covered by the annular frame 21 is a circle, and a through hole or a gap 222 is arranged on the circle. Fig. 2 is a circular through hole. The size of the through holes is smaller than the average diameter of the smoker particles so as to retain the smoker particles from entering and leaking.

In fig. 2, the annular frame 21 is in the shape of a circular ring. The central diaphragm 22 is in the shape of a circular disc having a diameter equal to the outer diameter of the annular frame 21. When the central diaphragm 22 and the annular frame 21 are combined, the outer edges of the two completely overlap.

The central diaphragm 22 is made of 25-100 g/m²Tissue paper of (2). The material of the annular frame 21 is 200-500 g/m²The jam of (2). The purpose is as follows: the strength of the annular frame 21 is greater than that of the central diaphragm 22, so that when the rear end spacer 2 is filled into the smoke tube 1 by interference fit, the annular frame 21 can bear a certain squeezing action and still be supported in the smoke tube 1.

As shown in fig. 3, the front end spacer 3 has the following specific structure: the front end spacer 3 is a sheet-like member including: an annular sheet 31 and a central spacer 32 bonded to the near lip end side of the annular sheet 31. The "near-lip side" is shown as the back of the ring segment 31 in the front view of fig. 3. Wherein, the center of the ring-shaped piece 31 is provided with a widened cross-shaped reserved gap 311. The boundary lines of the crossed reserved notch 311 are smooth curves without broken lines, so that the supporting effect can be improved, and the certain point can be prevented from being torn.

The cross-shaped reserved gap 311: 1. the radial strength of the ring-shaped piece 31 is enhanced to enhance the supporting function of the ring-shaped piece 31, prevent the ring-shaped piece 31 or the central isolation piece 32 from being torn, and 2, have the function of relatively guiding the sheet-type heating element so that the sheet-type heating element can be accurately inserted into the cross-shaped heating seam 321.

The center of the central isolation sheet 32 is provided with a cross-shaped heating seam 321, and the cross-shaped heating seam 321 is positioned in the center of the cross-shaped reserved gap 21. The cross-shaped heating seam 321 has the following functions: 1 when the cigarette of the utility model uses the central needle type or central rod type heating element for heating, the central isolation sheet 32 part at the heating seam 321 in the cross shape is easy to deform along the situation and is not torn when the heating element is inserted; 2 after the central heating element is pulled out of the cigarette, the central part of the central spacer 32 deformed can be restored to the original state or be restored to the original state by elasticity, and the particle smoking material in the cigarette is still blocked, so that the smoking set or the use environment is prevented from being polluted.

A central tearing-proof slit 322 which forms a certain angle with the cross-shaped heating seam 321 is arranged at the center of the cross-shaped heating seam 321. As shown in fig. 3, the central tear preventing slit 322 is two lines passing through the center of the heating slit 321 having a cross shape. Two central tear preventing slits 322 are arranged crosswise. The two central tear seams 322 and the cross-shaped heating seam 321 are in a shape of a Chinese character 'mi'. Each of the heating slits 321 in the cross shape is provided with 2 middle tearing slits 323 and 1 end tearing slits 324 which are distributed at intervals from the center along four directions. The middle tear seam 323 and the end tear seam 324 are perpendicular to the cross-shaped heating seam 321 communicating therewith. The length c of the central tear resistant seam 322 is 1/10 the length of the cross-shaped heating seam 321. Since the deformation of the sheet is smaller as the distance from the center of the heating slit 321 becomes larger, the length a of the end tearing preventive slit 324 is 0.5 to 0.8 times the length b of the middle tearing preventive slit 323. The front end spacer 3 is in a disc shape.

The central tear preventing seam 322, the middle tear preventing seam 323, and the end tear preventing seams 324 in combination function to: 1. when the heating element matched with the cigarette is a sheet type heating element or a cross-shaped heating element, when the heating element is inserted, the central spacing sheet 32 can be deformed in a self-adaptive manner along the directions of the central anti-tearing seam 322, the middle anti-tearing seam 323 and the tail end anti-tearing seam 324 by utilizing the elasticity of the paper, and the central spacing sheet 32 is not easy to tear; 2. after the sheet heating element or the cross heating element is pulled out of the cigarette, the central isolation sheet 32 can restore to the original shape or restore to the original shape by the elasticity of the paper, and still block the particle fuming material in the cigarette, so as to prevent the smoking set or the use environment from being polluted; 3. meanwhile, the cross-shaped heating slit 321, the central tear-preventing slit 322, the middle tear-preventing slit 323, and the end tear-preventing slits 324 allow air to flow in when suction is applied, since they are not completely sealed.

The central isolation sheet 32 can be 25-100 g/m²The annular sheet 31 of the thin paper can be 200-500 g/m²The jam of (2). The annular plate 31 has a greater strength than the central spacer 32.

Referring to fig. 4, the second embodiment provides a particle type cigarette, which comprises the self-plugging smoking section I of the first embodiment, and a cooling section II and a filter section III downstream of the self-plugging smoking section I.

The outer pipes of the cooling section II and the filter tip section III can be hollow pipes inserted with the smoke pipe 1 or hollow pipes integrally formed with the smoke pipe 1.

As shown in fig. 5, the third embodiment provides another rear-end separator 2. The difference between fig. 5 and the rear end spacer 2 in fig. 2 is: the circular through hole is replaced by an Contraband-shaped slit.

The advantages of the "Contraband" shaped slit are as follows: 1. when the hole is punched, the middle chip removal process of punching the through hole is saved; 2. the Contraband-shaped gap can not only utilize the elastic action of the spacer paper to better block the blocked particles, but also be opened towards the direction close to the lip end under the action of the suction force and the elastic action of the paper during the suction, and has good effect on the smooth passing of the smoke like a one-way valve combined in parallel; 3. the 'Contraband' shape gap width that unilateral interval set up is slightly bigger than circular through-hole, has reduced the preparation density of trompil cutting die on the paper die-cutting board, has just also reduced the preparation degree of difficulty. 3. When the whole isolation sheet is made of paper, the manufacturing cost of the paper cutter template is obviously less than the mold opening cost of the plastic part metal mold in the prior art.

As shown in fig. 6, the fourth embodiment provides another rear-end spacer 2. The differences between fig. 6 and the rear end spacer 2 in fig. 2 are: the circular through hole is replaced by a C-shaped gap.

The C-shaped gap has the advantages of the Contraband-shaped gap, and has the following characteristics:

compared with the Contraband-shaped gap, the C-shaped gap is simpler to manufacture because any one of the two cutting dies is used, the maximum nominal size of actual open holes of the two cutting dies is consistent to ensure the blocking effect on granular materials, and is smaller than the average diameter of granules, and the C-shaped cutting die is formed at one time without the problems that a cutter at the vertical corner of a square hole cutting die is difficult to machine and form or a cutter at the right angle is difficult to machine.

The effect of blocking particles is also better because square holes with the same side length and C-shaped holes with the same diameter have the same maximum nominal opening size, but the diagonal size of Contraband is larger than the diameter of the C-shaped holes, namely the actual hole area of the square holes is larger than the maximum actual size of the C-shaped holes, so that the blocking effect of the C-shaped holes is better.

As shown in fig. 7, the fifth embodiment provides a rear-end separator 2. The difference between fig. 7 and the rear end spacer 2 in fig. 2 is: the rear end spacer 2 further includes: and another annular frame 21, the two annular frames 21 sandwiching the central diaphragm 22.

As shown in fig. 8, the sixth embodiment provides a rear end spacer 2. The difference between the rear end spacer 2 in fig. 8 and fig. 6 is: the annular inner edge line of the annular frame 21 is circular, and the annular outer edge line is regular octagon.

As shown in fig. 9, the seventh embodiment provides a front end spacer 3. The difference between fig. 9 and the front end spacer 3 in fig. 3 is: the front end spacer 3 further includes another annular piece 31, and the two annular pieces 31 sandwich the center spacer 32.

As shown in fig. 10, the eighth embodiment provides a front end spacer 3. The difference between the front end spacer 3 in fig. 10 and fig. 9 is: the annular outer edge lines of the annular sheets 31 are regular octagons.

In fig. 8 or fig. 10, the outer diameter of the regular octagon is slightly larger than the inner diameter of the smoke tube 1. When the front end isolation sheet 3 or the rear end isolation sheet 2 is installed in the smoke tube, the slight extrusion deformation of the regular polygon convex end point and the point contact connection of the smoke tube 1 and the regular polygon non-contact arc section with proper elastic deformation are utilized. This is easier to install and more secure than the "line contact" between the disc-shaped spacer and the smoke tube 1 of the first embodiment. Meanwhile, the gap between the regular polygon front end spacer 3 or the rear end spacer 2 and the arc of the smoke tube 1 can be ventilated and can separate smoke particles.

Example 2

This example discloses a method for preparing the self-sealing smoking segment I in the first embodiment. In the whole preparation method, the related equipment comprises: the device comprises a first diaphragm filling mechanism 4, a smoke tube filling and clamping mechanism 5, a support rod mechanism 6, a rear end spacer conveying mechanism 7, a hopper 8, a front end spacer conveying mechanism 10 and a second diaphragm filling mechanism 11.

In the utility model, because the relative relation of the drawings of each station is continuous and is limited to space, in order to ensure that the drawing of each station is large enough and can be seen clearly, four reference surfaces are specially set, wherein I is a membrane input reference surface, II is a membrane transmission reference surface, III is a reference surface for isolating membrane installation, and IV is a membrane support member reference surface. In each station, all reference surfaces are on the same horizontal plane.

In fig. 11, at a station a, the first suction plate 42 sucks one piece of the rear end spacer 2 in a negative pressure manner for standby. The specific operation is as follows:

the first film loading mechanism 4 includes: a first upper cylinder 44, a first piston rod 43 and a first suction cup 42 which are coupled to each other. The rear end spacer transport mechanism 7 stores therein the rear end spacer 2. The rear spacer transport mechanism 7 is used to transport the rear spacers 2 to the film filling mechanism 4. The specific structure of the rear-end spacer conveying mechanism 7 is not limited.

The first piston rod 43 of the first upper cylinder 44 is a shaft member having a first through hole 45 formed in the center thereof. The first through hole 45 communicates with a negative pressure source. The first suction cup 42 is mounted to the lower portion of the first upper cylinder 44. The first suction disk 42 is opened with axially extending first suction holes 41. The first through hole 45 communicates with the first suction hole 41. The first air suction holes 41 in the first suction cup 42 are uniformly distributed at the positions, close to the offset edge, of the first suction cup 42, so that the annular frame 21 of the rear end spacer 2 to be installed is ensured to be in contact with the first air suction holes 41. This ensures that the first suction pad 42 can normally suck the rear end spacer 2 sent from below the first suction pad 42 when the negative pressure is transmitted from the first through hole 45 to the first suction hole 41. In the initial position, the bottom end surface of the first suction cup 42 is flush with the reference surface I. When the rear end spacer 2 is conveyed out from the rear end spacer conveying mechanism 7 to the position where the membrane filling mechanism 4 is located, one piece of rear end spacer 2 is sucked by the first suction disc 42, so that pressure change in the first suction hole 45 is caused, and then the first upper air cylinder 44 and the first suction disc 42 in the pneumatic system are triggered to lift the height of one piece of rear end spacer 2 upwards. Thereafter, the rear-end spacer conveying mechanism 7 exits this station.

IV reference level is as follows: an axially extending support rod 62 is provided in the support rod mechanism 6. The upper end of the support rod 62 is coupled to the support end surface 61 by a spring 63. The lower end of the support rod 62 is coupled to a support cylinder 64 by a spring 63. In the initial state, the support end face 61 is flush with the support datum level 6 and the spring 63 is in a compressed state. The support bar 62 is in the lowermost position. At this point, the work of station a is complete. The whole set of installation mechanism (comprising the first membrane filling mechanism 4 and the support rod mechanism 6) is shifted to the next station.

Referring to fig. 12-15, in the process of b station, initial time-b station and +3 time, the smoke tube 1 and the rear end spacer 2 are filled, or the smoke tube filling clamping mechanism 5 finishes filling the smoke tube 1 in the process of turning from the a station to the b station.

The smoke tube loading and clamping mechanism 5 comprises a smoke tube loading mechanism and a smoke tube clamping mechanism. The smoke tube clamping mechanism is provided with an axial smoke tube accommodating cavity.

Referring to fig. 12, at the b station, at the initial time, the first suction cup 42 sucks one piece of the rear end spacer 2 for standby under the action of the negative pressure. Below the I standard, the smoke tube loading and clamping mechanism 5 loads (clamps, inserts or clamps) the smoke tube 1 into the smoke tube clamping mechanism, and transfers the smoke tube 1 to the position shown in fig. 12, so that the smoke tube 1 is coaxially arranged with the first piston rod 43 and the supporting rod 62 of the supporting cylinder 64, and the far lip end of the smoke tube 1 is vertically placed upwards. The pipe loading mechanism may be of conventional design, such as a robot or the like, but may of course be a continuously feedable tubular conveyor feeder.

Fig. 13 shows the end face support at the time +1 at the b-position. The supporting cylinder 64 installed on the supporting rod mechanism 6 receives the action command, and the supporting rod 62 drives the supporting end surface 61 to extend into the smoke tube 1, so that the top of the supporting end surface 61 is equal to the far lip end of the smoke tube 1.

Fig. 14, at the b station, +2, the rear end spacer 2 is loaded. Under the action of the upper first upper cylinder 44 of the rear end spacer 2, the first piston rod 43 pushes the first suction disc 42 and drives the rear end spacer 2 adsorbed below to be loaded into the smoke tube 1. Meanwhile, the support cylinder 64 below the reference plane IV is placed in the neutral position air pressure state, at which time the support end surface 61 and the support rod 62 and the spring 63 are pushed down by the first piston rod 43. The spring 63 adds a certain damping in the process of being compressed, and assists the rear end spacer 2 to stably move downwards to a preset position in parallel, so that the rear end spacer is not inclined in the process of moving downwards. The area in the smoke tube 1 above the rear end spacer 2 forms a smoke agent containing area.

FIG. 15, at position b, time +3, reset. First, the negative pressure in the first vent hole 45 in the first piston rod 43 is closed to separate the first suction cup 42 from the rear end spacer 2, and then the first upper cylinder 44 is returned to the reference I position to level the bottom end surface of the first suction cup 42 with the reference I.

In fig. 16-17, fuming particles 9 are filled in the station c, the initial time to the station c and the +1 time.

In station c, as shown in fig. 16, a hopper 8 capable of quantitative filling is used for filling the smoke tube 1 with the fuming particles 9 at the initial moment. When the hopper 8 runs to the position that the hopper opening is over the center of the far lip end of the smoke tube 1, a filling signal is obtained, the valve 81 of the hopper 8 is opened, and the quantitative smoke particles 9 in the hopper 8 can be injected into the smoke agent containing area above the spacing piece 2 at the rear end in the smoke tube 1.

In fig. 17, at the c +1 station, the hopper 8 loading mechanism withdraws the far lip end of the smoke tube 1, the second diaphragm loading mechanism 11 operates near the far lip end of the smoke tube 1, and the front spacer conveying mechanism 10 conveys the front spacer 2, which specifically operates as follows: the second film loading mechanism 11 includes: a second upper cylinder 114, a second piston rod 113 and a second suction cup 112 connected to each other. The hopper 8 filled with the fuming particles 9 is evacuated above the far lip end of the smoke tube 1. Meanwhile, before the second diaphragm loading mechanism 11 is switched over the far lip end of the smoke pipe 1, the front end spacer delivery mechanism 10 delivers the front end spacer 2 from the direction perpendicular to the paper surface to the lower side of the second suction cup 112, and one piece of the front end spacer 2 is sucked by the second suction cup 112, causing the pressure change in the second through hole 115. Then, the second upper cylinder 114 lifts the second suction cup 112 together with the first front end spacer 2 to the highest position, so that the lower edge of the first front end spacer 2 coincides with the reference 1, and then the second diaphragm filling mechanism 11 moves to the central position above the far lip end of the smoke pipe 1.

Referring to fig. 18 to 20, the front end spacer 2 is loaded at the time of "d", the initial time ". d" and ". sup.2".

Referring to fig. 18, at the initial time of the station d, the second diaphragm filling mechanism 11 rotates or moves to a position right above the far lip end of the cigarette tube 1, and the second piston rod 113 and the second suction cup 112 are coincident with the axis of the cigarette tube 1.

As shown in fig. 19, at the time of +1 at the d-position, the second film loading mechanism 11 pushes the second piston rod 113 and the second suction cup 112 to move downward together, so that the front end spacer 3 pushes down the thickness of the front end spacer 3 under the action of the negative pressure. Then, the negative pressure suction in the second through hole 115 is stopped, and the front end spacer 3 loses the suction of the second suction cup 112. At this station, under the pushing of the second piston rod 113, the front end spacer 3 moves downward to be installed at the far lip end of the smoke tube 1, the stroke is short (the thickness of only one front end spacer 3), the relative auxiliary support of the smoke particles 9 is arranged below the front end spacer 3, and the maximum outer diameter of the front end spacer 3 is in proper interference fit with the inner wall diameter of the smoke tube 1. Therefore, although the front end spacer 3 is not supported by the supporting end surface 61 below the same as the rear end spacer 2, the front end spacer 3 is not turned over. The final blocking of the smoker particles 9 by the front spacer 3 is thus achieved.

As shown in fig. 20, at the time of +2 at the d-position, the second up cylinder 114 raises the second piston rod 113 to the highest position together with the second suction cup 112. The support cylinder 64 moves the support rod 62 down to the lowest position together with the support end surface 61 coupled to the upper end thereof, so that the smoke tube 1 is then released from the restraint.

Then, the second film filling mechanism 11 is evacuated from the station.

Fig. 21, e-station:

and after the smoke tube loading clamping mechanism 5 is removed, the self-plugging fuming section I is manufactured, and a self-plugging fuming section I is obtained. In the self-plugging smoking section I, the rear end spacer 2 is arranged at the near lip section of the smoke tube 1, and a section of cavity is reserved at the near lip end of the smoke tube 1. And then, a filter tip section III is arranged at the lip end close to the smoke pipe 1 of the self-blocking smoking section I, and a cavity is reserved to be used as a cooling section II, so that the finished product particle type cigarette is obtained.

The whole mechanism enters the installation preparation of the next smoke pipe 1 to complete the work of one period.

The positions of the stations can be circumferentially distributed on the circumference of a circle. The feeding mechanisms of the rear-end spacer conveying mechanism 7, the hopper 8 and the front-end spacer conveying mechanism 10 can be conveyed to corresponding stations from outside to inside along the circular radial direction. When the rear end spacer 2 and the front end spacer 3 are installed in the smoke tube 1, which surface of the rear end spacer 2 and the front end spacer 3 faces the lip-near end of the smoke tube 1 is determined according to requirements.

In an alternative embodiment, at station d, +1, the front spacer 2 loaded into the pipe 1 may be replaced with the rear spacer 2 to prepare another pellet-type cigarette, as shown in figure 22. The particle type cigarette comprises a self-blocking smoking section I, a cooling section II and a filter tip section III which are arranged at the downstream of the self-blocking smoking section I. The self-plugging smoking segment I comprises: the smoke tube comprises a smoke tube 1, a rear end spacer 2 arranged at the far lip end of the smoke tube 1, a rear end spacer 2 arranged at the near lip section of the smoke tube 1 and a particle-type smoke substance arranged between the two rear end spacers 2. The smoke tube 1 and the two rear-end spacers 2 are coaxially arranged.

Compared with the same part of the existing particle cigarette, the semi-finished particle heating cigarette produced by the utility model can obviously shorten the occupied length, and is completely made of degradable paper materials, thereby being more environment-friendly. The production equipment is put into one step by adopting the method of the utility model, and the granular cigarettes can be continuously produced.
