[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the application. Meanwhile, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.

[0029] Usually, the cigarette loading and unloading machine system is only equipped with one negative pressure system to provide negative pressure for various drums on the production line. This causes the negative pressure of the drum responsible for conveying the filter rods to be affected by other drums. Especially when the negative pressure of other drums is larger, the negative pressure of the drum responsible for conveying the filter rods will become smaller accordingly, resulting in the risk of filter rods falling during the process of conveying the filter rods.

[0030] For this purpose, refer to Figure 1 The present application provides a cigarette receiving and loading machine system, which includes a first negative pressure system 100 and a second negative pressure system 200. The first negative pressure system 100 is connected to a first drum wheel 300 for conveying filter rods and a second drum wheel 400 for conveying cigarettes (for example, including a smoke inlet drum wheel, a cigarette cutting drum wheel, a separation drum wheel, a merging drum wheel, etc.) to provide negative pressure to the first drum wheel 300 during the process of the first drum wheel 300 conveying filter rods, and to provide negative pressure to the second drum wheel 400 during the process of the second drum wheel 400 conveying cigarettes. The second negative pressure system 200 is connected to the first drum wheel 300 to provide negative pressure to the first drum wheel 300. The first drum wheel 300 includes a first drum wheel body 301 and a first air valve 302 connected to the first drum wheel body 301. The first negative pressure system 100 and the second negative pressure system 200 are respectively connected to the first air valve 302 to provide negative pressure to the first drum wheel body 301.

[0031] Among them, reference Figure 2 The second negative pressure system 200 includes a mounting seat 1, a negative pressure source 2 and a connecting pipe 3. The mounting seat 1 is arranged in gas communication with the first air valve 302. The negative pressure source 2 and the mounting seat 1 are connected through the connecting pipe 3. The negative pressure source 2 is used to generate negative pressure to provide negative pressure for the first air valve 302.

[0032] Specifically, an additional negative pressure system is provided for the first drum 300, which can ensure that the negative pressure provided by the first air valve 302 to the first drum body 301 is sufficient, and reduce the risk of the filter rod falling due to insufficient negative pressure during the process of conveying the filter rod by the first drum body 301. It can also ensure that impurities such as cigarette dust in the negative pressure pipe connected to the first air valve 302 are sucked away in time, reduce pipe blockage, make the negative pressure provided by the first air valve 302 more stable, and thus improve the stability of filter rod conveying.

[0033] In some embodiments, the second negative pressure system 200 only provides negative pressure for the first drum wheel 300. Specifically, the first negative pressure system 100 is a common negative pressure system in the original receiving machine system. On this basis, a second negative pressure system 200 is added to provide negative pressure for the first drum wheel 300. The second negative pressure system 200 and the first negative pressure system 100 do not interfere with each other, so that the negative pressure of the first drum wheel 300 is less affected by other drum wheels, further improving the negative pressure stability of the first drum wheel 300 and reducing the risk of filter rods falling.

[0034] In some embodiments, the first drum 300 comprises a filter rod straightening drum. The second negative pressure system 200 can increase the suction force of the filter rod straightening drum, reduce the risk of filter rods not being in place during the straightening process, and improve the stability of filter rod transfer.

[0035] In other embodiments, the first drum 300 further includes a cutting drum and a staggered drum. That is, the cutting drum, the staggered drum, and the filter rod straightening drum are all used to transfer filter rods, and share the first air valve 302. Thus, the second negative pressure system 200 can provide negative pressure to the cutting drum, the staggered drum, and the filter rod straightening drum at the same time through the first air valve 302, thereby improving the stability of the filter rod transfer at each drum.

[0036] refer to Figure 3 In some embodiments, the mounting base 1 includes at least two pipe interfaces 11. At least two pipe interfaces 11 are respectively connected to the negative pressure source 2 through the connecting pipe 3. The two pipe interfaces 11 can ensure the air volume between the mounting base 1 and the negative pressure source 2, so that the negative pressure provided by the second negative pressure system 200 is more sufficient and stable.

[0037] refer to Figure 4 In some embodiments, the mounting base 1 further includes a body 12 and a groove 13. The groove 13 is provided on one side of the body 12 for connecting with the first air valve 302, and at least two pipe interfaces 11 are connected with the groove 13. The groove 13 is used to connect with the first air valve 302, thereby increasing the air circulation space between the mounting base 1 and the first air valve 302, and ensuring the air volume.

[0038] In order to further increase the air circulation space between the mounting base 1 and the first air valve 302 , in some embodiments, the groove 13 extends along the length direction of the main body 12 .

[0039] In some embodiments, the main body 12 is threadedly connected to the first air valve 302. In this way, the mounting base 1 and the first air valve 302 can be easily disassembled or connected.

[0040] In some embodiments, a plurality of threaded holes (eg, three) are disposed at intervals on the main body 12 to improve the connection stability between the main body 12 and the first air valve 302 .

[0041] In some embodiments, the main body 12 is a rectangular plate-shaped member. The rectangular plate-shaped member is easy to manufacture and convenient to open the groove 13 and the pipe interface 11 on the rectangular plate-shaped member within a limited space.

[0042] refer to Figure 2 In some embodiments, the second negative pressure system further includes an adapter 4 and a reducer 5. The input end of the adapter 4 is used to connect to the mounting seat 1. The output end of the adapter 4 is used to connect to the first end of the reducer 5. The second end of the reducer 5 is used to connect to the negative pressure source 2.

[0043] Specifically, the adapter 4 has two input ends and one output end, and the two input ends are respectively connected to the two pipe interfaces 11 through the two connecting pipes 3, thereby the airflows in the two connecting pipes 3 are aggregated in the adapter 4. Since the pipe diameter of the negative pressure source 2 does not match the pipe diameter of the output end of the adapter 4, a reducing joint 5 is provided to connect the negative pressure source 2 to the output end of the adapter 4 through the reducing joint 5.

[0044] In some embodiments, the adapter 4 includes a three-way connector, which is hung on the wall of a production workshop to facilitate the pipeline layout and has a neat and beautiful appearance.

[0045] refer to Figure 2 In some embodiments, the reducer 5 includes a docking section 51 and a reducing section 52. The first end of the docking section 51 is used to connect to the output end of the adapter 4. The second end of the docking section 51 is used to connect to the first end of the reducing section 52. The second end of the docking section 51 is used to connect to the negative pressure source 2. The diameters of the docking section 51 and the reducing section 52 are different. The diameter of the reducing section 52 matches the diameter of the negative pressure source 2.

[0046] Specifically, the reducer 5 is configured according to the requirements, and it is only necessary to match the diameter of the docking section 51 with the diameter of the output end of the adapter 4 , and to match the diameter of the reducer section 52 with the diameter of the pipeline of the negative pressure source 2 .

[0047] In other embodiments, the docking section 51 and the diameter-reducing section 52 may be arranged to be detachably connected, for example, connected to each other by threads. In this way, when the negative pressure source 2 is changed, resulting in a change in the diameter of the negative pressure source, only a new diameter-reducing section 52 may be designed and replaced to ensure that the first end of the diameter-reducing section 52 matches the second end of the docking section 51, and the second end of the diameter-reducing section 52 matches the pipeline of the negative pressure source 2, without having to replace the docking section 51, thereby reducing the design cost.

[0048] The present application also provides a cigarette production system, including the cigarette receiving and loading machine system as described above.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution for protection in the present application.
