In recent years, new types of tobacco have been rapidly developed, and heated cigarettes are gradually moving into the global market with low-harm characteristics. In the tobacco industry, heated non-burning cigarettes have been commonly referred to as heated cigarettes. The heating cigarette adopts a low-temperature heating and baking mode, and the smoking section of the conventional internal heating cigarette is relatively short, and is generally 12-20mm. The cutting length of the cigarette rods manufactured by the common cigarette making machine is shortest to be about 50mm under the influence of the cutting principle of the cutter head of the existing cigarette making machine. The current feeding mechanism for heating the four-length smoke generating section of the cigarettes can cut the four-length smoke generating section produced by the cigarette machine into a single-length smoke generating section, enter a tipping machine, combine with a double-length filter tip to form a combination of a single-length smoke generating section, a double-length filter tip section and a single-length smoke generating section, and finally form a complete cigarette after cutting and turning. The following disadvantages may occur with this attachment method:
1. in the rubbing and connecting process of the connector, the smoke section is too short and is positioned on two sides of the whole body, so that the roundness of the cigarettes is poor;
2. the smoke section is generally shorter and the filter tip section is relatively longer, when the filter tip section is wrapped by tipping paper, the whole filter tip section and part of the smoke section are required to be covered, the proportion of the tipping paper in the whole cigarette length is greatly increased compared with that of a traditional cigarette, and the consumption of tipping materials is increased;
3. a part of heating cigarettes adopt laser drilling, the drilling position is generally in a filter tip section, if the current tipping form is adopted, laser at least needs to be penetrated through tipping paper and filter rod forming paper at the same time, the power consumption requirement on a laser drilling machine is higher, and the tipping speed can be influenced correspondingly.

The specific meaning of the above terms in the present embodiment can be understood in a specific case by those of ordinary skill in the art.
To make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in further detail below.
Fig. 1 shows a conventional bonding process. In the traditional cigarette tipping process, a filter tip section is cut into a double-length main body, a smoke section is connected into a tipping machine through receiving, cutting, parallel cutting and re-cutting, and separation to form an inner double-row and outer double-row single-length smoke section, and the inner double-row and inner double-row single-length smoke section and the double-length filter tip section form a single-length smoke section, a double-length filter tip section and a single-length smoke section, namely the filter tip section is arranged in the middle, the smoke section is arranged at two ends of the axial direction of the filter tip section, and the single-length smoke section, the double-length filter tip section and the single-length smoke section are wrapped into a whole through tipping paper, so that a double-length cigarette is wrapped, and the combination is divided into two from the middle to form two complete cigarettes. As can be seen in fig. 1 and 2, the conventional cigarette tipping process cuts the central filter segment so that the filter segment is fully wrapped with tipping paper and the smoke segment is only partially wrapped. The internal heating cigarette is long in filter tip section and short in smoke section, so that more tipping paper is consumed in comparison with a traditional tipping mode, and the outward end part of the smoke section is easy to leak threads in the tipping process.
Referring to fig. 3, the present invention provides a cigarette tipping process comprising the steps of: cutting raw materials: cutting the multiple length filter tip section into 1 time length filter tip sections, and cutting the multiple length smoke generating section into 2 time length smoke generating sections; splicing: centering the 2-time long cigarette making section, respectively arranging two sections of 1-time long filter tip sections at two axial ends of the 2-time long cigarette making section for splicing, and wrapping and rubbing the two sections by using tipping paper to form 2-time long cigarettes; cutting cigarettes: and cutting the cigarettes with the length of 2 times along the axial direction from the middle to form cigarettes with the length of 1 time.
The multiple length filter segments may be, for example, 4-fold length filter segments or 6-fold length filter segments, and the multiple length filter segments may be cut to form two or more 1-fold length filter segments. The multiple length cigarette making section can be, for example, 4 times length cigarette making section, and two sections of 2 times length cigarette making section with the same length can be obtained after cutting. The multiple length herein refers to the multiple length of the length that the cigarette has after being finally formed by itself. For example, a 4-fold length filter segment is 4 times the length of the filter segment forming the interior of the cigarette and a 2-fold length smoke segment is 2 times the length of the smoke segment forming the interior of the cigarette.
In the tipping process of the embodiment, the 1-time long filter tip is arranged at two ends of the smoke generating section to form a combination of the 1-time long filter tip section, the 2-time long smoke generating section and the 1-time long filter tip section, the combination is arranged in parallel, the combination is wrapped by tipping paper, and then the tipping paper is split from the middle, namely the smoke generating section positioned in the middle is split, and the obtained 1-time long cigarette is shown in figure 4. The tipping paper is applied to the middle part of the cigarette with the length of 2 times, so that the fuming section in the cigarette with the length of 1 time finally formed can be completely wrapped by the tipping paper.
In the invention, the study objects are arranged in parallel, namely in the same column, namely the axial directions of the study objects are positioned in the same straight line, and the study objects are arranged in parallel, namely in the same row, namely the radial directions of the study objects are positioned in the same straight line.
Specifically, referring to fig. 3, in the above raw material splitting step, the multiple-length smoke generating segment is located at the position a, and the multiple-length smoke generating segment is split into parallel 2-length smoke generating segments, namely, 2-length smoke generating segments at the position B, and the parallel 2-length smoke generating segments, namely, 2-length smoke generating segments at the position B are arranged according to the y direction in fig. 3. Thereafter, the 2-fold length of smoke segments are gathered together in the same row and delivered downstream. For example, a 4-fold long smoke generating section is cut into two side-by-side 2-fold long smoke generating sections, namely, two 2-fold long smoke generating sections form two rows which are respectively used as raw materials of 2-fold long cigarettes. The 2-time long cigarette emitting sections are gathered into the same row, for example, two parallel 2-time long cigarette emitting sections which are just cut can be staggered, namely, parallel materials are arranged in a staggered mode, so that the axial directions of the two sections are not in the same straight line, specifically, for example, the two 2-time long cigarette emitting sections at the position B are respectively arranged front and back to form two 2-time long cigarette emitting sections shown at the position C, one section is arranged at the position of the same row as the other section, namely, the two 2-time long cigarette emitting sections at the position D are arranged along the x direction to form two 2-time long cigarette emitting sections which are arranged side by side, and then the two 2-time long cigarette emitting sections are sequentially conveyed to the downstream.
Further, in the raw material cutting step, after the multiple length filter tip sections are cut, parallel 1-time length filter tip sections composed of two sections are formed, and the parallel 1-time length filter tip sections are separated in the axial direction, so that an interval is formed between the two parallel 1-time length filter tip sections in the axial direction, and the interval is transmitted to the downstream. Thus, a 2-fold length of the segment is delivered downstream and placed in the gap, after which the segment-segment is gathered and spliced.
Specifically, the multiple length filter tip section is a 4-time length filter tip section, and in the raw material segmentation step, the multiple length filter tip section also comprises the steps of carrying out primary segmentation on the 4-time length filter tip section to obtain a 2-time length filter tip section, and carrying out secondary segmentation on the 2-time length filter tip section after being gathered into the same row to form two rows of 1-time length filter tip sections. The same row is formed, for example, by first arranging two 2-fold length filter segments which are in parallel relationship after cutting, so that the two filter segments are staggered front and back, and then placing one of the two filter segments in the same row with the other filter segment, and sequentially transferring the two filter segments to the downstream. Correspondingly, the multiple long smoke generating section is a 4-time long smoke generating section, the 4-time long smoke generating section is cut to form a 2-time long smoke generating section, and the 2-time long smoke generating section is just matched with two separated filter tip sections to form a 2-time long cigarette. In other embodiments, the multiple length filter segments are 6 times longer filter segments, and the parallel double cutters can be used to cut the 6 times longer filter segments once to obtain three parallel 2 times longer filter segments, and then the three 2 times longer filter segments are gathered into the same row and then cut twice to form three rows of 1 times longer filter segments, each row comprising two 1 times longer filter segments. Correspondingly, the multiple length cigarette emitting sections can be arranged to match the number of the cut filter tip sections after cutting, and the multiple length cigarette emitting sections and the two separated 1-time length filter tip sections are matched to form a 2-time length cigarette.
Further, in the cigarette segmentation step, two parallel cigarettes with the length of 1 time are formed after the middle segmentation, then the two parallel cigarettes with the length of 1 time are adjusted to be parallel cigarettes with the same orientation, namely, the two cigarettes with the length of 1 time are positioned in the same row, and then the cigarettes are transmitted to the downstream.
In addition, the cigarette cutting step further comprises the step of detecting whether the cigarettes with the length of 1 time are qualified or not, if not, rejecting, and if so, transmitting to downstream for outputting. For example, it may be detected whether a cigarette is leaking, loose-tipped, or missing filter segments or smoke segments.

As described above, the multiple length filter segments that the cigarette tipping machine of the invention can be used to cut may be 4-length filter segments or 6-length filter segments, which after cutting may form two or more 1-length filter segments. The cigarette tipping machine of this embodiment sets up 1 time length filter tip at the both ends of fuming section, forms the combination parallel arrangement of "1 time length filter tip section+2 time length fuming section+1 time length filter tip section". The tipping paper feeding device 3 transmits the cut tipping paper to the splicing device 4 through the roller, and the '1 time long filter tip section +2 time long smoke generating section +1 time long filter tip section' which are arranged in parallel is rolled in the process of rotating the roller.

The smoke generating segment cutting wheel 22 of this embodiment is provided with a cutting portion, and the cutting portion contacts with the smoke generating segment on the smoke generating segment cutting wheel 22, for example, cuts a 4-time length smoke generating segment into two segments of parallel materials with equal length. The slitting section includes a spacing rail (not shown) that fixes the 4-fold length of the object and a fuming section cutter 25, and cuts it into two equal length sections with the fuming section cutter 25. The smoke section slitting wheel 22 transmits the two parallel smoke sections after cutting to the smoke section dislocation wheel 23, and the smoke section dislocation wheel 23 dislocates the two parallel materials, so that the two parallel materials can be arranged in a front-back dislocation and continuously conveyed to the downstream, namely, the two parallel materials are conveyed to the smoke section gathering wheel 24. The smoke generating segment gathering wheel 24 is used for gathering the smoke generating segments with the length of 2 times and transmitting the smoke generating segments to the downstream.
The filter segment feeding device 1 comprises a slitting assembly and a separating wheel 15.

Criteria for eligibility are, for example, detection of whether a cigarette is leaking, or whether a loose-end cigarette is present, or whether a missing smoke segment or filter segment is present. If the cigarettes are qualified, the qualified cigarettes are transmitted to the downstream, and if the cigarettes are not qualified, the cigarettes can be rejected through a rejection wheel 48. The rejecting wheel 48 can reject cigarettes detected as unacceptable by the detecting wheel 47 by compressed air, for example. In addition, the cigarette tipping machine of the present embodiment further includes a sampling wheel 49 connected to the reject wheel and an output wheel 40 connected to the sampling wheel 49. The sampling wheel 49 allows for non-stop sampling by the tipping machine when cigarette sampling is desired. The output wheel 40 outputs the finished cigarettes to downstream facilities.
With the above-described cigarette tipping process and cigarette tipping machine, in one embodiment, the total length of the heated cigarette is 45mm and the diameter is 7.2mm. The length of the smoke generating section and the length of the filter tip section are respectively 15mm and 30mm, and the length of the tipping paper is 18mm. That is, the length of the smoke generating section (4 times length) is 60mm, the length of the filter tip section (4 times length) is 120mm, and the length of the tipping paper (2 times length) is 36mm.
In another embodiment, the total length of the heated cigarette is 46mm and the diameter is 7.8mm. The length of the smoke generating section and the filter tip section are 13mm and 33mm respectively, and the length of the tipping paper is 17mm. That is, the length of the smoke generating section (4 times length) is 52mm, the length of the filter tip section (4 times length) is 132mm, and the length of the tipping paper (2 times length) is 34mm.
Compared with the traditional mode, the cigarette tipping process or the cigarette tipping machine using the cigarette tipping machine of the invention has the following advantages:
(1) The smoke generating section is positioned in the middle after being rubbed and cut off in the final stage, so that the rubbing roundness of the cigarettes can be improved, and the end part yarn falling in the process is reduced;
(2) Because the internal heating cigarette smoke section is much shorter than the filter tip section, the consumption of tipping paper can be reduced by wrapping tipping paper on the smoke section;
(3) For the heated cigarettes needing to be subjected to laser drilling on the filter tip section, the cigarettes manufactured by the tipping technology only need to be perforated with the forming paper, so that the energy consumption of laser drilling can be effectively reduced, and the overall production efficiency of the cigarettes is improved;
(4) Because the cigarette paper and the tipping paper are wrapped outside the smoke generating section, the appearance of the smoke generating section is more upright and is not easy to deform, and meanwhile, substances in the smoke generating section are prevented from penetrating out of the cigarette paper to influence the attractiveness of the cigarette paper.
While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a further detailed description of the invention with reference to specific embodiments, and it is not intended to limit the practice of the invention to those descriptions. Various changes in form and detail may be made therein by those skilled in the art, including a few simple inferences or alternatives, without departing from the spirit and scope of the present invention.
