[0040] The present application provides a ternary composite structure of a heating type cigarette, such as Figure 1As shown, it includes a filter rod segment 1, a particle segment 2 and a filter tip segment 3 which are connected in sequence. The filter rod segment 1 is provided with a low suction resistance filter rod, the particle segment 2 is provided with metal powder, and the filter tip segment 3 is provided with an opening 31.

[0041] Through the ternary composite structure, a low-resistance filter rod is added to the front filter rod segment 1 to block the particle segment 2, so that tobacco particles are not easy to fall off during the insertion and removal of the heated cigarette. The particle segment 2 is provided with metal powder.

[0042] In one embodiment, the low suction resistance filter rod has a pressure drop of 10-100 Pa / cm and a length of 2-5 mm.

[0043] Furthermore, the particle segment 2 is provided with tobacco particles, the tobacco particles contain a smoke generating agent, and the metal powder includes an iron-nickel alloy powder. The particle segment 2 has a length of 22-30 mm.

[0044] In one embodiment, the steps of preparing the iron-nickel alloy powder include:

[0045] (1) low-temperature drying, crushing and screening the tobacco dust raw material;

[0046] (2) adding iron-nickel alloy powder and a thickener, granulating, and microwave drying to obtain tobacco powder particles with a microporous structure;

[0047] (3) spraying the tobacco dust particles obtained in step (2) and adding 10-50% of a smoke generating agent to obtain low-temperature heated non-combustion tobacco particles with a particle size of 100-130 mesh;

[0048] In another embodiment, in the above step (3), the iron-nickel alloy is separately prepared into alloy particles having the same size as the tobacco particles, and the alloy particles are mixed with the tobacco particles in the particle segment 2; so that the mass of the alloy particles accounts for 10-50% of the total mass of the particle segment 2.

[0049] Adding metal alloys to the particle section 2 through the filling device 5 makes the tobacco particles heated more evenly and fully, and the smoke volume is more sufficient, which is beneficial to improving the sensory smoking quality.

[0063] (5) The cut cigarettes are moved along the conveyor to the twisting and joining position, and enter the twisting and joining device 9 at the twisting and joining position to complete the twisting, wrapping and rolling of the cigarettes to obtain finished cigarettes.

[0064] The smoking device of the present application scheme uses a commercially available electromagnetic heating smoking device, which heats the filter rod segment 1 and the particle segment 2 to generate smoke to release aroma. The smoke further passes through the filter segment 3, and the burning sensation is reduced to a suitable smoking temperature.

[0065] As an embodiment of this application:

[0066] The conveyor belt 4 is a filter rod forming machine conveyor belt 4. The receiving device 6 above the conveyor belt 4 includes a base fixed to the conveyor belt 4. The base extends upward to form a semi-cylindrical groove 61 with an opening facing upward. A half-height gram-weight forming paper is arranged in the groove 61. In this embodiment, the forming paper is selected to be 120 grams;

[0067] The shaping paper moves in the groove 61 following the conveyor belt 4. When it moves to the filling position, the filling device 5 located above the filling position is sequentially provided with a filter rod feeding module 51, a particle filling module 52 and a filter tip feeding module 53. A low-resistance filter rod, tobacco and metal particles and a acetate tip rod are placed into the shaping paper through the filter rod feeding module 51, the particle filling module 52 and the filter tip feeding module 53 to obtain a ternary composite structure of a filter rod segment 1, a particle segment 2 and a filter tip segment 3; wherein the low-resistance filter rod is 3 mm long, the particle segment 2 is 15 mm long, the acetate tip rod is 15 mm long, and alloy powder and a thickener are added to the particle segment 2, granulated, and microwave dried to obtain tobacco dust particles with micropores, and a smoke generating agent is sprayed and added to the tobacco dust particles to obtain low-temperature heating non-combustion tobacco particles with a particle size of 100-130 meshes;

[0068] After the filling is completed, the paper continues to move along the conveyor belt 4 to the splicing position, and the shaping paper placement device 7 above the splicing position puts shaping paper to cover the ternary composite structure, and splices with the original half shaping paper; in this process, the splicing and fixing of the shaping paper can adopt the splicing gluing method in the prior art.

[0069] After the splicing is completed, the conveyor belt 4 moves to the cutting position and is cut by the cutting device 8;

[0070] After the cutting is completed, the cigarettes are moved along the conveyor belt 4 to the twisting and splicing position, and the cigarettes are twisted and rolled by the twisting and splicing device 9;

[0071] At the same time, a laser punching device is also provided. In this embodiment, the filter segment 3 is provided with a pressure drop of 100-300Pa / cm.

The shaping paper placement device 7 is provided with a half shaping paper that has been cut in advance, and only one cut shaping paper is dropped each time when falling, so that its opening is downwardly spliced ​​with the shaping paper in the groove 61. The shaping paper placement device 7 is provided with a feeding device, and the feeding device is provided with a push rod. When the shaping paper falls, the push rod is moved down by a preset distance to push the shaping paper to dock with the shaping paper in the groove 61, so as to avoid the shaping paper in the shaping paper placement device 7 from shifting during the falling process and enhance the stability of the shaping paper splicing.

[0072] In addition, a glue dispenser is provided. When the filling reaches the splicing position, the glue dispenser dispenses glue on the ternary composite structure obtained by the filler, and the glue is applied to the surface of the shaping paper located in the groove 61, that is, at the splicing position with the other half of the shaping paper. Then, the shaping paper placing device 7 drops the other half of the shaping paper for splicing, further enhancing the splicing stability and firmness of the two halves of the shaping paper, and avoiding relative displacement between the two halves of the shaping paper during the subsequent movement. In addition, this method does not require the shaping paper in the groove 61 to be coated with a glue layer in advance, thereby avoiding the glue layer from sticking to the filling material when the filling device 5 is filling.

[0073] The unloading equipment can select a hydraulic rod, or select a motor-screw combination to realize the reciprocating movement of the push rod, and the specific implementation method can be realized with the help of existing technology.
