Description

Technical Field

[0001] This utility model relates to the field of cigarette mold box technology, and in particular to a self-cleaning ash blowing device for cigarette mold box production. Background Technology

[0002] Cigarette packaging machines are crucial equipment in cigarette production, responsible for packaging cigarettes in a 7-6-7 arrangement into packs. The internal cigarette conveying mechanism includes synchronous pulleys, a synchronous belt fitted onto the pulleys, and cigarette molds mounted on the outer surface of the synchronous belt. Packaging machines can operate at speeds up to 400 packs per minute. The cigarette conveying mechanism requires continuous material feeding and changing, constantly inputting and outputting cigarettes from the cigarette molds. During the conveying process, due to processes such as patting and alignment, agitation and loosening, as well as the directional movement and vibration of the belt, tobacco shreds at the cigarette ends can easily fall out and become stuck in the cigarette molds and the pulley supports, affecting the stability of the equipment. Therefore, production personnel add dust removal devices to the cigarette conveying mechanism to prevent... Dust or tobacco embedded in the cigarette mold box is blown out. For example, Chinese patent document CN202222191272.7 discloses a dust removal device and packaging machine for a cigarette conveying mechanism, used to remove tobacco dust from the cigarette conveying mechanism. The cigarette conveying mechanism has a first guard plate and a second guard plate on each side, which are parallel to each other. The dust removal device includes: a suction hood, which is located on the first guard plate, with multiple upper suction ports along a first direction. The cigarette mold box passes through each upper suction port sequentially as it moves along the first direction. The suction hood is connected to a workshop dust collection channel, which provides negative pressure to the upper suction ports; and a blowing mechanism, including multiple jet nozzle groups, each jet nozzle group located on the second guard plate, with the output end of each jet nozzle group facing the cigarette mold box or the timing belt. This patent effectively cleans tobacco dust from the cigarette conveying mechanism, preventing tobacco dust from entering the packaging with the cigarette assembly, improving product quality, and also avoiding excessive tension of the timing belt. However, during the blowing process, a large amount of dust and soot are scattered, especially when the dust removal equipment is turned on and off. The dust will fly to the outside of the first and second guard plates, affecting the operator's work and also affecting the product quality.

[0003] Therefore, it is necessary for those skilled in the art to provide a self-cleaning dust blowing device for cigarette mold box production, which can clean the cigarette mold box separately, prevent dust or smoke from scattering, ensure a clean production environment, and improve product quality.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please see Figure 1 , Figure 2 This utility model provides a self-cleaning dust removal device for cigarette mold box production, used to remove dust and clean the cigarette conveying mechanism 20. The cigarette conveying mechanism 20 includes a driving component 21, a conveying component 22 that rotates around the driving component 21, and a cigarette mold box 23 that is installed on the conveying component 22 and moves with the conveying component 22. The driving component 21 includes, but is not limited to, a motor. The conveying component 22 is strip-shaped and is installed on the output shaft of the driving component 21. The conveying component 22 rotates around the output shaft of the driving component 21 under the drive of the driving component 21, thereby driving the cigarette mold box 23 on the conveying component 22.

[0024] In this embodiment, the specific structure of the cigarette conveying mechanism 20 can be found in a nested cigarette fixing box conveying mechanism disclosed in Chinese Patent CN216611742U. The specific structure will not be described in detail here.

[0025] Please see Figures 3-7 The self-cleaning dust-blowing device for cigarette mold box production includes a dust-collecting housing 10, which is a hollow square shell structure. A blowing device 11 and a suction device 12 are installed on the dust-collecting housing 10. The conveying component 22 on the cigarette conveying structure 20 passes through the dust-collecting housing 10. The blowing device 11 and the suction device 12 on it blow dust and suction dust on the cigarette mold box 23 installed on the conveying component 22 to achieve self-cleaning.

[0026] This utility model places the cleaning process of the cigarette mold box 23 inside the sealed dust collection housing 10. The blowing device 11 and the suction device 12 are both installed in the internal cavity of the dust collection housing 10, which effectively prevents the scattering of dust and smoke, ensures the cleanliness of the processing environment, and greatly reduces the size of the processing equipment.

[0027] Furthermore, the side wall of the vacuum cleaner housing 10 is provided with an opening 16, which penetrates the walls of two opposite side walls of the vacuum cleaner housing 10. The conveying component 22 is connected in the two openings 16 and is movably disposed in the vacuum cleaner housing 10, thereby enabling the sequential cleaning of multiple cigarette mold boxes 23 on the conveying component 22.

[0028] In this embodiment, the through hole 16 is opened in the middle of the side wall of the dust collection housing 10, ensuring that there is enough cavity inside the dust collection housing 10 for installing the blowing device 11 and the suction device 12.

[0029] In this embodiment, an extended partition 18 is provided inside the dust collection housing 10 at the outlet 16. The extended partition 18 is sleeved on the outside of the conveyor 22. A barrier curtain 19 is installed on the extended partition 18. The barrier curtain 19 is made of plastic film and is attached to the outside of the conveyor 22. In use, the barrier curtain 19 isolates the inside of the dust collection housing 10 from the outside, forming a relatively sealed structure. This ensures that dust and smoke cannot escape from the internal cavity of the dust collection housing 10, improving the cleaning and recycling effect and thus ensuring the cleanliness of the processing environment.

[0030] Furthermore, a partition plate 13 is provided in the internal cavity of the dust collection housing 10. The partition plate 13 extends downward from the top wall of the dust collection housing 10 and abuts against the conveyor 22. In this way, the partition plate 13 divides the internal cavity of the dust collection housing 10 from left to right into a dust collection cavity 15 and a dust blowing cavity 14. At the same time, a connecting channel 17 is also formed in the dust collection housing 10 below the conveyor 22. The dust collection cavity 15 and the dust blowing cavity 14 are connected to each other through the connecting channel 17. The blowing device 11 is installed in the dust blowing cavity 14, and the suction device 12 is installed in the dust collection cavity 15. Meanwhile, the cigarette mold box 23 on the conveyor 22 faces the dust blowing cavity 14. In this way, the blowing device 11 blows the dust and cigarette dust on the cigarette mold box 23 into the connecting channel 17, and the suction device 12 blows out the dust and cigarette dust that have entered the dust collection cavity 15, thus completing the cleaning.

[0031] Furthermore, the air blowing device 11 includes a mounting base 111, on which a plurality of air blowing pipes 112 are mounted. An air inlet channel 113 is provided in the wall of the mounting base 111. One end of the air inlet channel 113 is connected to an air pump (not shown in the figure), and the other end of the air inlet channel 113 is connected to the air blowing pipes 112. The end of the air blowing pipes 112 away from the mounting base 111 is located above the cigarette mold box 23. In use, high-pressure gas is introduced into the air inlet channel 113 by the air pump. The high-pressure gas passes through the air inlet channel 113 and the air blowing pipes 112 and is sprayed toward the cigarette mold box 23 to achieve cleaning. Since the conveyor 22 is movably installed inside the vacuum housing 10, the cigarette mold box 23 located on the conveyor 22 moves along with it and continuously passes under the air blowing pipe 112, thereby realizing automatic cleaning of the cigarette mold box 23. Multiple air blowing pipes 112 can effectively ensure the comprehensiveness of cleaning, and the adjustable angle can clean the dead corners of the cigarette mold box 23, improving the cleaning effect.

[0032] Furthermore, the suction device 12 includes a fixed base 121 and a rotating head 122. The fixed base 121 is detachably connected to the inner wall of the suction cavity 15 using fasteners such as bolts or screws. One end of the fixed base 121 penetrates the wall of the suction housing 10, and the other end of the fixed base 121 is movably connected to the rotating head 122. The rotating head 122 has a flat plate-like structure, and multiple suction ports 123 are opened on the side of the rotating head 122 away from the fixed base 121. The fixed base 121 is provided with a suction channel 124. One end of the suction channel 124 is connected to a negative pressure pump (not shown in the figure), and the other end of the suction channel 124 is connected to the suction port 123. In use, the air in the suction channel 124 is drawn out by the negative pressure pump, thereby forming a negative pressure at the suction port 123, so as to suck out the dust or soot in the suction cavity 15, ensuring the stability of use and achieving cleaning.

[0033] In this embodiment, one end of the rotating head 122 is provided with a spherical connector (not shown in the figure), and the fixed base 121 is provided with a spherical locking interface (not shown in the figure). The spherical connector is fitted into the spherical locking interface to ensure that the rotating head 122 can be movably installed in the fixed base 121. The installer can adjust the angle of the rotating head 122 according to the settings of the air blowing device 11 to ensure the accuracy of dust suction.

[0034] In this embodiment, four suction devices 12 are provided, and the four suction devices are evenly arranged on the top wall of the dust suction cavity 15. Multiple dust suction ports 123 are provided and evenly arranged, so as to maximize the dust suction area of ​​the dust suction ports 123, improve the dust removal effect of this utility model, and effectively prevent dust from escaping.

[0035] In this embodiment, the rotating head 122 has a diversion channel (not shown in the figure) inside its wall. The diversion channel connects to multiple suction ports 123. The diversion channel is connected to the air intake channel 124 via a flexible hose. One end of the air intake channel 124 penetrates the wall of the fixed base 121 to connect to the negative pressure pump. The other end of the air intake channel 124 is connected to the diversion channel via the flexible hose, thereby achieving connection between the multiple suction ports 123. The flexible hose is made of plastic. The flexible hose ensures that the rotating head 122 does not affect the connection between the air intake channel 124 and the suction ports 123 while rotating, thus ensuring operational stability.

[0036] The specific operation method of this utility model is as follows: start the cigarette conveying mechanism 20, and continuously input and output cigarettes in the cigarette mold box 23. The partially empty cigarette mold box 23 passes through the dust collection housing 10, and the blowing device 11 on the dust collection housing 10 blows the dust from the cigarette mold box 23. Then, the suction device 12 sucks out the dust and cigarette dust in the dust collection cavity 15 and discharges it to a fixed position to achieve cleaning.

[0037] This invention places the cleaning process of the cigarette mold box 23 within a sealed dust collection housing 10. Both the blowing device 11 and the suction device 12 are installed within the internal cavity of the dust collection housing 10, effectively preventing the dispersion of dust and smoke, ensuring a clean processing environment, and significantly reducing the size of the processing equipment. This invention utilizes the barrier curtain 19 to isolate the interior and exterior of the dust collection housing 10, forming a relatively sealed structure, ensuring that dust and smoke cannot escape from the internal cavity of the dust collection housing 10, improving the cleaning and recycling effect, and thus ensuring a clean processing environment. Simultaneously, since the conveyor 22 is movably installed within the dust collection housing 10, the cigarette mold box 23 located on the conveyor 22 moves along with it and continuously passes under the blowing pipe 112, thereby achieving automatic cleaning of the cigarette mold box 23. Multiple blowing pipes 112 effectively ensure comprehensive cleaning, and the adjustable angle allows for cleaning of the dead corners of the cigarette mold box 23, improving the cleaning effect.

[0038] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
