[0023] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described, but the present invention is not limited to these embodiments.

[0024] Example 1

[0025] A feeding device, such as Figure 1 As shown: Includes several material cutting frames 1, according to Figure 1 In the direction of the center, several feeding frames 1 are arranged sequentially along the front-to-back direction. Each feeding frame 1 is side-sealed, with an inlet at the top and an opening at the bottom. The interior is hollow and communicates with the inlet and opening, thus forming a feeding channel. The feeding frame 1 is typically composed of four steel plates connected sequentially. The steel plates can be square, forming a cuboid structure; or they can be isosceles trapezoids, forming a shape like... Figure 1 The bucket-shaped feeding frame 1 shown is a feeding frame 1 with an inlet area larger than an outlet area, and its inner wall is inclined to facilitate feeding. In addition, in this embodiment, the bottom outlet end faces of several feeding frames 1 are located on the same horizontal plane.

[0026] Below several feeding frames 1, a guide frame 2 is also provided. The guide frame 2 is also side-sealed, with an inlet at the top and an opening at the bottom. It is hollow inside and communicates with the inlet and opening, thus forming a guiding channel. In this embodiment, the guide frame 2 is composed of four square steel plates connected sequentially to form a cuboid structure. When the guide frame 2 moves below a feeding frame 1, the inner cavity of the guide frame 2 communicates with the inner cavity of that feeding frame 1, forming a complete channel for the tobacco material to pass through, thus completing the feeding of the tobacco material. The top inlet area of ​​the guide frame 2 should not be less than the bottom outlet area of ​​the feeding frame 1 to ensure that the material in the feeding frame 1 can completely enter the guide frame 2.

[0027] In some embodiments, a dustproof curtain 21 can be installed at the bottom outlet of the guide frame 2 to prevent material leakage and dust generation caused by material spillage. The dustproof curtain 21 is usually made of a wear-resistant flexible material, such as a rubber sheet. After being rolled into a cylindrical shape, the upper end is fixed to the outer wall or bottom end face of the guide frame 2, and the lower end is suspended. If necessary, a distance can be cut vertically upward at the lower end of the cylindrical dustproof curtain 21 to form at least two friction parts. The friction parts can abut against the conveyor belt of the subsequent process located at the outlet of the guide frame 2, and the opening between adjacent friction parts allows the material to leave the inner cavity of the dustproof curtain 21 under the action of the conveyor belt.

[0028] To prevent tobacco material from leaking through the gap between the feeding frame 1 and the guide frame 2 during feeding, and to facilitate connection between the guide frame 2 and different feeding frames 1, the guide frame 2 and any feeding frame 1 are detachably connected. The detachable connection method is not limited; in this embodiment, a magnetic connection is used, which simplifies assembly and disassembly. Specifically, an iron plate is installed on the outlet end face of the feeding frame 1, and an electromagnet is installed on the inlet end face of the guide frame 2. By energizing or de-energizing the electromagnet, the connection or disconnection between the guide frame 2 and the feeding frame 1 is controlled.

[0029] To move the guide frame 2 below the unloading frame 1 that needs to be unloaded, an adjustment structure is also included. The adjustment structure is not limited; to ensure the accuracy of the movement of the guide frame 2, in this embodiment, the adjustment structure first includes a guide member 31. The guiding direction of the guide member 31 is the same as the arrangement direction of the several unloading frames 1. Commonly used guide members 31 are tracks or slide rails. Tracks often cooperate with wheels, and slide rails often cooperate with sliders. In this embodiment, as... Figure 1 As shown, the arrangement direction of the several feeding frames 1 is a straight line from front to back, and the guide member 31 is a track, the guiding direction of which is its length direction, which is also a straight line from front to back. In order to ensure the balance of the guide, there are two tracks, which are arranged parallel to each other on both sides of the guide frame 2. In some embodiments, if the arrangement direction of the several feeding frames 1 is curved, the track can also be set to a corresponding curved shape.

[0030] The adjustment structure further includes a power component 32 for driving the guide frame 2 to move along the guide member 31. The structure of the power component 32 is not limited. For example, when the guide member 31 is a slide rail, the power component 32 can be a slider that can be inserted into the slide rail. Then, the slider is connected to the guide frame 2. In use, the guide frame 2 is pushed to move below the corresponding unloading frame 1. Another example is as in this embodiment, such as... Figure 2As shown, the guide member 31 adopts a track. The power member 32 includes wheels 321 rotatably mounted on opposite sides of the guide frame 2, and a motor 322 for driving the wheels 321. Specifically, the motor 322 body is mounted on the guide frame 2, and the output shaft of the motor 322 is connected to the wheel axle of the wheels 321 via a reducer. The wheels 321 are then mounted on the two tracks. Driven by the motor 322, the wheels 321 can rotate, and simultaneously, under the action of friction, they move along the track. When using a straight track, ordinary wheels 321 can be used; when using a curved track, it is preferable to set the outer diameter of the wheels 321 to increase gradually from away from the guide frame 2 to closer to the guide frame 2. This arrangement is similar to train tracks and train wheels, ensuring that the wheels 321 remain close to the track as the guide frame 2 moves along the curve.

[0031] In some implementations, the feeding frame 1 is equipped with a positioning device, such as an infrared sensor or laser detection, to detect whether the guide frame 2 has moved into place.

[0032] Based on the above structure, the feeding device of this application can be completed. When the feeding device of a certain feeding frame 1 delivers material, the motor 322 is started, so that the guide frame 2 moves along the guide member 31 to the bottom of the feeding frame 1. Then the electromagnet is started, so that the guide frame 2 and the feeding frame 1 are connected to form a complete channel for the material to pass through.

[0033] Example 2

[0034] This embodiment is basically the same as embodiment 1, except that the structure of the feeding frame 1 is different.

[0035] Since the feeding frame 1 is fixed, and the guide frame 2 needs to cooperate with the track, neither the feeding frame 1 nor the guide frame 2 can move freely in the vertical direction. Therefore, it is usually necessary to control the end face of the guide frame 2 where the inlet is flush with the end face of the feeding frame 1 where the outlet is to ensure a magnetic connection between the guide frame 2 and the feeding frame 1 without gaps. However, in this case, the guide frame 2 will inevitably come into contact with other feeding frames 1 during the movement, and there will be friction between them. This will affect the movement of the guide frame 2 and also affect the fixation of the feeding frame 1.

[0036] Therefore, in this embodiment, as Figure 3As shown, each feeding frame 1 includes a fixed part 11 and a movable part 12. Both the fixed part 11 and the movable part 12 are cylindrical structures. The fixed part 11 is located at the top, with an inlet at its top; the movable part 12 is located at the bottom, with an outlet at its bottom. Based on this, when the movable part 12 is slidably connected to the fixed part 11 in the vertical direction, the height of the outlet end face of the feeding frame 1 can be adjusted. Specifically, when the feeding frame 1 needs to be connected to the guide frame 2, the movable part 12 is moved down so that the outlet end face can contact the inlet end face of the guide frame 2, completing a seamless magnetic connection; when the feeding frame 1 does not need to be connected to the guide frame 2, the movable part 12 is moved up so that a gap is formed between the outlet end face and the inlet end face of the guide frame 2, without affecting the passage of the guide frame 2 from below.

[0037] The sliding connection method is unrestricted. The fixed part 11 can be fitted over the movable part 12, with a slider on the outer wall of the movable part 12 and a vertical groove on the inner wall of the fixed part 11. The movable part 12 slides vertically through the cooperation of the slider and the vertical groove. Alternatively, the movable part 12 can be fitted over the fixed part 11, with a slider on the inner wall of the movable part 12 and a vertical groove on the outer wall of the fixed part 11. The latter arrangement is preferred. When the movable part 12 is fitted over the fixed part 11, the upper inner diameter of the feeding frame 1 is smaller and the lower inner diameter is larger, making it less likely for material to adhere to the inner wall of the movable part 12 when falling through the feeding frame 1, thus preventing it from affecting the sliding of the movable part 12. Furthermore, even if material adheres to the inner wall of the movable part 12, it can be scraped off by the action of the lower end of the fixed part 11 during the up-and-down movement of the movable part 12.

[0038] To more easily control the movable part 12 of the feeding frame 1 to move downward when necessary and upward when unnecessary, in this embodiment, an elastic element 13 that extends and retracts vertically is provided between the fixed part 11 and the movable part 12. A preferred arrangement is as follows: a first protrusion is provided at the lower end of the outer wall of the fixed part 11, a second protrusion is provided at the upper end of the inner wall of the movable part 12, and the elastic element 13 is provided between the first and second protrusions. The function of the elastic element 13 is as follows: when it is necessary to connect the guide frame 2, the movable part 12 is attracted downward by the magnetic attraction of the electromagnet of the guide frame 2, thus compressing the elastic element 13; when it is no longer necessary to connect the guide frame 2, the electromagnet is disconnected, and the elastic element 13 rebounds upward, pushing the movable part 12 upward through elasticity, thus forming a gap between the outlet end face and the inlet end face of the guide frame 2. Furthermore, in this arrangement, there is no requirement for the outlet end faces of the several feeding frames 1 to be flush, making the installation tolerance of the feeding frames 1 higher.

[0039] In addition, in this embodiment, the guide frame 2 is set as a bucket shape with a large inlet area and a small outlet area, and its inclined inner wall facilitates the sliding of materials.

[0040] Example 3

[0041] A tobacco feeding device, such as Figure 4 As shown, the system includes several feeding devices 4, each providing different materials, such as different flavors of cigarettes. Each feeding device 4 has a conveying device 5 at its outlet for conveying the materials. It also includes a packaging device 6 for receiving the materials. The packaging device 6 includes a feed belt positioned below the outlets of the conveying devices 5, allowing materials from different conveying devices 5 to be received by the same feed belt in the packaging device 6.

[0042] To ensure that the material from the conveying device 5 can smoothly fall onto the feed belt of the packaging device 6, a feeding device as described in Embodiment 1 or Embodiment 2 is also included. Several feeding frames 1 in the feeding device are respectively located at the outlets of each conveying device 5, preferably in a fixed connection. For example, the top inlet end face of the feeding frame 1 is welded to the supports on both sides of the conveyor belt of the conveying device 5. The top inlet area of ​​the feeding frame 1 is not less than the outlet area of ​​the conveying device 5, so that all the material can enter the feeding frame 1. A guide frame 2 in the feeding device is located between the feeding frame 1 and the feed belt.

[0043] When the packaging device 6 needs a certain flavor of cigarettes, the guide frame 2 moves along the guide 31 to the bottom of the corresponding feeding frame 1 of the feeding device 4, and then the electromagnet is activated so that the guide frame 2 and the feeding frame 1 are connected to form a complete channel, so that the cigarettes of the required flavor can fall onto the feeding belt after passing through.
