Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery, specifically to a cigarette machine air chamber suction ribbon cleaning device. Background Technology

[0002] A cigarette rolling machine is a machine that rolls tobacco into cigarettes using cigarette paper. It consists of four main parts: tobacco feeding, forming, cutting, and weight control, as well as auxiliary parts such as printing and dust removal. The forming part comprises two parts: the suction belt and the cigarette gun. The suction belt is a porous conveyor belt through which the tobacco is transported to the cigarette gun. To promptly clean any debris carried by the suction belt, cigarette rolling machines are usually equipped with a suction belt cleaning device. Traditional cigarette rolling machines use ordinary tobacco, which is easy to clean. However, heated cigarette rolling machines use reconstituted tobacco, which has a high glycerin content and is very sticky, making it difficult to clean off the suction belt.

[0003] Utility model patent CN219519698U discloses a ribbon cleaning device, including a suction chamber and a suction ribbon rotatably disposed within the suction chamber. A cleaning box is located within the suction chamber, and the suction ribbon passes through the cleaning box. A cleaning mechanism is located within the cleaning box, comprising an air inlet pipe, a suction pipe, and an upper pressure block. The upper pressure block is positioned above the suction ribbon, and its lower surface has multiple air holes for blowing air onto the suction ribbon. The upper pressure block is connected to the air inlet pipe, and the input end of the suction pipe is located below the suction ribbon, while its output end extends to the outside of the cleaning box. This ribbon cleaning device has a simple structure. As the suction ribbon passes through the cleaning box, the cleaning mechanism removes impurities from the ribbon, which are then sucked away by the suction pipe. This prevents impurities from drifting within the suction chamber and entering the bearings of the roller assembly or being drawn into the cigarette machine through the suction port of the suction chamber, thus preventing equipment damage. However, this ribbon cleaning device uses a suction-type cleaning method, which has relatively low suction power and is not suitable for cleaning highly viscous reconstituted tobacco. Utility Model Content

[0004] In order to utilize high-pressure airflow to clean highly viscous residues on the suction ribbon and improve cleaning ability and effect, the technical solution adopted by this utility model is: a cigarette machine wind chamber suction ribbon cleaning device, including a wind chamber and a suction ribbon rotatably disposed in the wind chamber;

[0005] A negative pressure port is provided on one side of the air chamber, and an air nozzle for airflow into the suction ribbon is provided on the top of the air chamber. A collection trough is provided below the suction ribbon, and the collection trough is connected to the negative pressure port through a guide pipe. The negative pressure port is used to introduce negative pressure into the collection trough through the guide pipe.

[0006] Based on the above, in order to facilitate the collection of blown-off residue by the collection tank, the collection tank is arranged vertically and vertically corresponding to the jet nozzle.

[0007] Based on the above, in order to facilitate the control of the high-pressure gas flow rate in the nozzle, a throttling mechanism is provided on the nozzle.

[0008] Based on the above, in order to vertically spray air onto the suction ribbon, the bottom of the air nozzle passes through the side wall of the air chamber and is positioned above the suction ribbon.

[0009] Based on the above, the jet nozzle is connected to a high-pressure gas.

[0010] Based on the above, the negative pressure interface is externally connected to a negative pressure mechanism, which can be a blower.

[0011] Based on the above, in order to expand the collection range, the top width of the collection trough is greater than the outlet width of the jet nozzle.

[0012] This utility model has substantial features and progress compared with the prior art. Specifically, the cigarette machine air chamber suction ribbon cleaning device provided by this utility model cleans the suction ribbon by using high pressure and negative pressure respectively. On the one hand, it can use the air passage to blow out high pressure airflow to clean the debris remaining on the suction ribbon, and the debris that has been cleaned off is taken away through the guide pipe.

[0013] Simultaneously, the guide pipe directs the positive pressure airflow from the air duct to the air intake of the air chamber, preventing airflow turbulence inside the air chamber and sucking away the high-pressure air and blown-off residue along with it. This allows for the use of high-pressure airflow to clean highly viscous residues on the suction belt. Therefore, this device features strong cleaning ability and excellent cleaning effect.

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0018] Example 1

[0019] This embodiment provides a cigarette machine air chamber suction ribbon cleaning device, such as... Figure 1 , Figure 2 As shown, a cigarette machine air chamber suction ribbon cleaning device includes an air chamber 1 and a suction ribbon 3 rotatably disposed within the air chamber 1. A negative pressure port 8 is provided on one side of the air chamber 1, and an air nozzle 7 for spraying air onto the suction ribbon 3 is provided on the top of the air chamber 1. A collection trough 5 is provided below the suction ribbon 3, and the collection trough 5 is connected to the negative pressure port 8 via a guide pipe 6. The negative pressure port 8 is used to introduce negative pressure into the collection trough 5 through the guide pipe 6.

[0020] To facilitate control of the high-pressure gas flow rate within the nozzle 7, a throttling mechanism 4 is provided on the nozzle 7. For vertical jetting of the suction ribbon 3, the bottom of the nozzle 7 passes through the side wall of the air chamber 1 and is positioned above the suction ribbon 3.

[0021] Specifically, the jet nozzle 7 is externally connected to high-pressure gas. The negative pressure interface 8 is externally connected to a negative pressure mechanism, which can be a blower. The suction ribbon 3 rotates cyclically via the suction ribbon pulley assembly 2.

[0022] Example 2

[0023] This embodiment provides a cigarette machine air chamber suction ribbon cleaning device. The main difference from embodiment 1 is that in this embodiment, in order to facilitate the collection of blown-off residues by the collection trough 5, the collection trough 5 and the air nozzle 7 are arranged vertically and vertically in correspondence.

[0024] Example 3

[0025] This embodiment provides a cigarette machine air chamber suction ribbon cleaning device. The main difference from embodiment 1 is that, in order to expand the collection range, the top width of the collection groove 5 is greater than the air outlet width of the jet nozzle 7.

[0026] Specifically, the working principle of the cigarette machine air chamber suction ribbon cleaning device provided by this utility model is as follows:

[0027] High-pressure air is blown onto the suction ribbon through a throttling mechanism and a jet nozzle, blowing off the residue on the ribbon. At the same time, the negative pressure interface guides the negative pressure through a guide pipe to a collection tank, which then sucks away the high-pressure air blown out by the jet nozzle and the blown-off residue.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
