Problems solved by technology

[0005] 1. Tobacco stick-type heat-not-burn products take a long time to warm up. Since the filamentous tobacco filler tightly packed along the axis of the cigarette prevents the heat from propagating from the central heating sheet to the outer tobacco filler along the radial direction of the cigarette, the tobacco The central area of ​​the rod is fully heated, but the outer peripheral area away from the central heating sheet is not sufficiently heated, the heat utilization efficiency is low, and the overall heating of the tobacco rod is uneven
In addition, since the shredded tobacco fillers arranged in the axial direction are packed tightly and the heating sheet is inserted into the tobacco rod axially, the resistance is relatively large when the tobacco rod is inserted and pulled out, and the heating sheet is easy to break
[0006] 2. Granular tobacco type heat-not-burn products have low compatibility, and can only use their own pods, with small smoke volume and mild tobacco taste
Although patents have reported tobacco particle-type heat-not-burn cigarettes that look similar to traditional cigarettes (CN201811489706.3, CN201811487278.0, CN201811488351.6), they are mainly manufactured by adding granular tobacco fillers to paper empty tubes. Cigarettes, the particles are in a loose state in this type of non-rolling cigarettes. In order to prevent the particles from falling from the cigarettes, it is necessary to add a blocking device to the end (open end) of the cigarette away from the mouth rod to seal the particles. Increased the complexity of cigarette manufacturing and posed new challenges to the high temperature resistance, sealing and air permeability of the sealing device
The paper empty tube is made of multiple layers of paper, which has high hardness, poor air permeability and heat transfer efficiency
In addition, cigarettes cannot be manufactured through the rolling process because paper empty tubes are used to fill granules to manufacture cigarettes, and automatic cigarette manufacturing equipment cannot be used for assembly line operations to manufacture cigarettes

Embodiment 1

[0048] A method for manufacturing non-combustible cigarettes based on flocking technology, the method includes a flocking process and a cigarette rolling process; wherein, the flocking process sequentially includes a cloth rolling step, a gluing step 8, and a flocking step , drying step 9, washing step 10. The flocking step adopts an electrostatic flocking method.

[0049] Such as figure 1 As shown, the specific operations of each step of the flocking process are as follows:

[0050] The cloth rolling step: place 3 rolls of cigarette paper in the paper feeding system;

[0051] The gluing step 8: spraying the adhesive 2 on the inner surface of the cigarette paper 3;

[0052] The flocking step: embedding and fixing the tobacco filler 1 in the adhesive 2 coated on the inner wall of the cigarette paper 3 of the cigarette;

[0053] The drying step 9: drying and curing the adhesive 2 on the surface of the cigarette paper 3 flocked with the tobacco filler 1 at a certain temperatu...

Embodiment 2

[0064] A method for manufacturing non-combustible cigarettes based on flocking technology, the only difference from Example 1 is that the flocking step adopts mechanical flocking.

[0065] The equipment used in the mechanical flocking step can use existing suitable mechanical flocking equipment, and only adjust the mechanical and electrical parameters of the equipment according to the characteristics of the cigarette paper and tobacco filler.

[0066] The specific operation is as follows:

[0067] The cigarette paper 3 coated with the adhesive 2 is passed over a set of polygonal rollers 7 which rotate rapidly to vibrate the cigarette paper 3 and drive the tobacco filler 1 into the adhesive 2 . The tobacco filler 1 is applied to the cigarette paper 3 from a hopper 4 by gravity. The tobacco filler 1 is adhered to the surface of the cigarette paper 3 to form a densely packed flocking layer 20 .

Embodiment 3

[0070] Such as image 3 3-1 is a radial cross-sectional view of a tobacco segment of a non-burning cigarette manufactured using the manufacturing method of Example 2 of the present invention. The cigarette rod comprises a tobacco segment including the cigarette paper layer 31 wrapped in the outermost periphery. The cigarette paper layer 31 is a hollow cylindrical structure, and the inner wall of the cigarette paper layer 31 is provided with an adhesive layer 21 , and the tobacco filler particles 11 are fixedly bonded to the adhesive layer 21 . The tobacco filler particles 11 are circumferentially arranged along the inner wall of the cigarette paper layer 31 to form a tobacco filler particle layer, the number of the tobacco filler particle layer is one layer, and the number of the binder layer is one layer . The inside of the cigarette paper layer 31 is filled with the tobacco filler particles 11 to be hollow. The adhesive layer 21 is formed by coating the adhesive 2 . The ...

Abstract

The invention belongs to the technical field of heating cigarette manufacturing, and particularly relates to a method for manufacturing a non-combustion type cigarette based on a flocking technology.The method comprises a flocking procedure and a cigarette rolling and connecting procedure. The flocking procedure comprises a flocking step, and the flocking step is to flock the tobacco filler (1) on the cigarette paper. The method for manufacturing the non-combustion type cigarette based on the flocking technology is provided for the first time, the flocking technology is adopted for automatically flocking filamentous or fibrous or granular tobacco to the surface of cigarette paper, then the cigarette rolling and connecting procedure is connected, and the non-combustion type cigarette can be obtained. When the cigarette is filled with tobacco filler particles, the complex process of adopting a plugging device at the opening end of the cigarette is omitted. When the cigarette is filled with tobacco filler filaments or fibers, the heat resistance of heat spreading in the radial direction of the cigarette is greatly reduced, and the defects that an existing cigarette is large in heat resistance, low in heat transfer rate and uneven in heating are overcome.

Description

technical field [0001] The invention belongs to the technical field of heating cigarette manufacturing, in particular to a method for manufacturing non-combustible cigarettes based on flocking technology. Background technique [0002] In recent years, the sales volume of commercially available new heat-not-burn tobacco products represented by iQOS has continued to rise, and the recognition and acceptance of consumers have increased significantly. Its heat-not-burn tobacco sticks (cigarettes) are closer to the shape of traditional cigarettes. The tobacco filler in the tobacco rod is a filamentous filler, which is arranged along the axial direction of the cigarette rod, and the tobacco rod (cigarette rod) is heated by inserting the central heating sheet of the tobacco rod along the axial direction of the tobacco rod to generate inhalable smoke. Another type of heat-not-burn tobacco product represented by ploom tech adopts the pod (capsule) form between the traditional cigarett...
