[0029] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0030] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0031] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0032] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0033] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0034] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0035] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0036] In the cigarette processing and production process, tobacco shreds are stored in a tobacco storage room. When the cigarette rolling equipment needs to process the tobacco shreds, they are sequentially transported through a conveyor, a vibrator, and an inclined conveyor to a tobacco feeder. The tobacco feeder then transports the tobacco shreds through pipes to the cigarette rolling equipment. In the existing technology, because the tobacco feeder is large and inconvenient to move, the tobacco shreds need to be manually moved to the feeding device (conveyor) multiple times, which is labor-intensive and inefficient.

[0037] To address the aforementioned problems, this embodiment provides a tobacco processing system, including a cigarette rolling machine and a feeding device, see reference. Figures 1-4 The feeding device includes a feeding assembly, a hopper 10, a connecting pipe 20, and a blower assembly. The hopper 10 is connected to the cigarette rolling machine via the connecting pipe 20 and a flexible pipe. A pulley is installed at the bottom of the feeding assembly. The hopper 10 is located at the discharge end of the feeding assembly. The hopper 10 is funnel-shaped with an open end at the top, the inner diameter of which is larger than the inner diameter of the closed end. Tobacco shreds enter the hopper 10 through the feeding assembly and the open end. A through hole is provided on the side wall of the hopper 10 near the closed end. The connecting pipe 20 is located in the through hole and communicates with the hopper 10, allowing the tobacco shreds to exit the hopper 10 through the connecting pipe 20. The blower assembly is located inside the hopper 10 to loosen the tobacco shreds and blow them into the through hole. By placing the hopper 10 on the feeding assembly and moving the feeding assembly to the location of the tobacco shreds, manual handling of the tobacco shreds is avoided, saving labor costs and improving the efficiency of reprocessing recycled tobacco shreds.

[0038] In this embodiment, the blower assembly includes a high-speed fan and an air compressor. It should be noted that since the tobacco loosening equipment and blower assembly are mature technologies in the prior art, they will not be described in detail here. Specifically, the connecting pipe 20 can be configured as multiple sections, or it can be a combination of rigid pipe and flexible pipe.

[0039] Furthermore, to increase the efficiency of tobacco entering the cigarette rolling machine, two through holes and two connecting pipes 20 are provided opposite each other. In other embodiments, more than two through holes and two connecting pipes 20 can be provided depending on the size of the hopper 10 to improve the tobacco feeding efficiency.

[0040] Furthermore, the hopper 10 has a square cross-section, and two through holes are provided on the two first sidewalls 11 of the hopper 10. In other embodiments, the cross-section of the hopper 10 may be circular or triangular.

[0041] Furthermore, the feeding device also includes a guide member 30, which is disposed on the horizontal central axis of the second side wall 12 of the hopper 10 and has two arc-shaped guide surfaces. The two arc-shaped guide surfaces extend from the central axis of the hopper 10 toward the two through holes to guide the tobacco to the through holes. In this embodiment, the guide member 30 is configured as two guide plates 31, one end of which is connected to each other and the connecting end is located on the horizontal central axis of the hopper 10, and the other end extends toward the two through holes respectively. The two guide plates 31 are recessed toward the central axis. In other embodiments, the guide member 30 can be configured as a block. Specifically, the width of the guide plate 31 is the same as the gap between the two second side walls 12. This prevents the tobacco from falling directly into the bottom of the hopper 10 and accumulating.

[0042] Furthermore, the guide member 30 also includes a fixing plate 32, with two guide plates 31 welded or screwed to the fixing plate 32, and the fixing plate 32 fixed to the second side wall 12.

[0043] Furthermore, the second sidewall 12 is rotatably provided with an operation window 40. In this embodiment, the operation window 40 is square, and a hinge 41 is provided at the lower end of the operation window 40 for rotating the operation window 40. A buckle or quick clip 42 is provided at the upper end of the operation window 40 for easy and quick fixation of the operation window 40. The operator can open the operation window 40 to clean the inside of the hopper 10.

[0044] Furthermore, transparent observation windows 50 are provided vertically on both first sidewalls 11. Specifically, a detection component 60 is provided on the outside of the first sidewall 11 to detect the accumulation of tobacco shreds in the hopper 10 through the transparent observation windows 50. In this embodiment, the transparent observation windows 50 can be made of glass or resin, etc.

[0045] Furthermore, the feeding device also includes a flap assembly 70, which includes a first flap 71. The first flap 71 is rotatably disposed on the inner side of the second side wall 12 along the central axis in the horizontal direction. The rotating end of the first flap 71 can swing around in the horizontal direction to selectively guide the tobacco shreds to one of the two through holes. Specifically, the first flap 71 can achieve three postures. When the first flap 71 is placed vertically along the central axis, both through holes can supply tobacco shreds. When the first flap 71 swings to the right, the left through hole can supply tobacco shreds. When the first flap 71 swings to the left, the right through hole can supply tobacco shreds. By selectively controlling the first flap 71, one feeding device can supply tobacco shreds to two cigarette machines, improving the tobacco shred supply efficiency.

[0046] Furthermore, the width of the first flap 71 is the same as the distance between the two second sidewalls 12. The rotating end of the first flap 71 is provided with a rotating shaft, which can be connected to a motor or a handle to control the swing of the first flap 71 electrically or manually. Furthermore, the flap assembly 70 also includes a second flap 72, which has the same structure as the first flap 71. The second flap 72 is vertically spaced below the first flap 71 to prevent the first flap 71 from being unable to guide the tobacco due to the excessive length of the hopper 10.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
