[0032] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0033] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] like Figure 1As shown, this utility model provides a tobacco dispensing device. The tobacco dispensing device includes a hopper 1, a channel opening and closing mechanism 4, a dispensing mechanism 2, and a position adjustment mechanism 3. The top of the hopper 1 has a feeding channel 11, and the bottom of the hopper 1 has at least two spaced-apart discharge channels 12. The channel opening and closing mechanism 4 is installed in the hopper 1 and is configured to open or close the discharge channels 12. The dispensing mechanism 2 includes a dispensing roller 21 and a first drive motor 22. The dispensing roller 21 is rotatably installed in the hopper 1 and located in the feeding channel 11. The first drive motor 22 can drive the dispensing roller 21 to rotate at a preset direction and speed, and the position adjustment mechanism 3 is installed in the hopper 1 and can adjust the position of the dispensing roller 21 so that the dispensing roller 21 can distribute tobacco material into the corresponding discharge channels 12 according to a preset ratio. The tobacco dispensing device is also equipped with a controller, which is connected to the first drive motor 22, the position adjustment mechanism 3 and the channel opening and closing mechanism 4 to control their operation; a position sensor 36 is installed on the feeding channel 11 to monitor the position and moving distance of the dispensing roller 21, and the position sensor 36 is connected to the controller.

[0036] Specifically, when it is necessary to change the distribution ratio of tobacco material entering the discharge channel 12, the discharge channel 12 that does not need to discharge is first closed by the channel opening and closing mechanism 4. Then, the controller controls the position adjustment mechanism 3 to adjust the position of the distribution roller 21 in the feed channel 11. The controller controls the first drive motor 22 to drive the distribution roller 21 to rotate at a preset position with a preset direction and a preset speed. The tobacco material falls onto the distribution roller 21 and is then thrown out. The tobacco material falls into the inlet of each discharge channel 12 according to the preset falling path, so that the tobacco material can be distributed to each opened discharge channel 12 according to the preset ratio, thereby realizing the distribution of tobacco material.

[0037] In this embodiment, the controller controls the position adjustment mechanism 3 to adjust the position of the distributing roller 21, which can replace manual adjustment of the position of the distributing roller 21. The distributing roller 21 rotates at the target position at a preset speed and preset direction, thereby distributing the tobacco material into the corresponding discharge channel 12 according to a preset ratio. This eliminates the need to manually adjust the position of the distributing roller 21 to adjust the distribution ratio of the tobacco material, saving adjustment time, reducing labor intensity, avoiding delays in production progress, and thus improving production efficiency.

[0038] It should be noted that the controller contains data relating the position, direction, and speed of the dispensing roller 21 to the range of tobacco material falling. Based on this data and the monitoring information from the position sensor 36, the controller can control the operation of the first drive motor 22, the position adjustment mechanism 3, and the channel opening / closing mechanism 4 to achieve the desired dispensing effect. Preferably, the controller can also be a controller with a control panel for operation by a staff member.

[0039] It should also be noted that the inlets of each discharge channel 12 can be considered to be on the same horizontal plane. When the tobacco material falls, its projection perpendicular to this horizontal plane is the falling area. The area of ​​the falling area overlapping with the inlet of the discharge channel 12 is called the falling area of ​​the discharge channel 12. This falling area corresponds to the flow rate of the tobacco material in the discharge channel 12. When the flow rate of the tobacco material in a discharge channel 12 is higher or lower than the expected value, the rotation speed and position of the distributing roller 21 can be adjusted to decrease or increase the falling area, thereby adjusting the flow rate of the tobacco material in the discharge channel 12.

[0040] like Figure 2 As shown, in some embodiments of this utility model, at least two discharge channels 12 include a first channel 121, a second channel 122 and a third channel 123 distributed sequentially along the length of the hopper 1. The three channels are arranged at intervals at the bottom of the hopper 1, and their tops are connected to form a channel opening and closing space. The channel opening and closing mechanism 4 is arranged in the channel opening and closing space and cooperates with the position movement of the distributing roller 21 to open or close the discharge channel 12.

[0041] Specifically, along the length of the feeding channel 11, the side of the feeding channel 11 closest to the tobacco material conveying device is the rear plate 113, and the opposite side is the front plate 112. The first channel 121, the second channel 122, and the third channel 123 are sequentially connected to the bottom of the feeding channel 11 along the direction from the front plate 112 to the rear plate 113, and all three extend downwards at an incline. The side containing the rear plate 113 is defined as the rear side, and the side containing the front plate 112 is defined as the front side, wherein the first channel 121 extends at an incline towards the front, and the second channel 122 and the third channel 123 extend at an incline towards the rear. When it is necessary to close part of the discharge channel 12, the position adjustment mechanism 3 adjusts the position of the distributing roller 21 to assist the channel opening and closing mechanism 4 in closing part of the discharge channel 12.

[0042] In some embodiments of this utility model, the channel opening and closing mechanism 4 includes a rotatable first distributing plate 41 and a second distributing plate 42, and two rotary actuators 43 corresponding to the two. The first distributing plate 41 is rotatably connected to the hopper 1 via a first rotating shaft and is located at the entrance of the first channel 121. One rotary actuator 43 can drive the first distributing plate 41 to rotate via the first rotating shaft to open or close the entrance of the first channel 121. The second distributing plate 42 is rotatably connected to the hopper 1 via a second rotating shaft and is located at the entrance of the second channel 122. The other rotary actuator 43 can drive the second distributing plate 42 to rotate via the first rotating shaft to open or close the entrance of the second channel 122. The distributing roller 21 can move to or away from the entrance of the third channel 123 to close or open it.

[0043] Specifically, two rotary actuators 43 are mounted on the side plate of the feed channel 11 and are respectively connected to the first rotary shaft and the second rotary shaft. When the tobacco material does not need to be discharged from the second channel 122, the rotary actuators 43 drive the second distributing plate 42 to rotate, thereby closing the entrance of the second channel 122. When the tobacco material does not need to be discharged from the third channel 123, the distributing roller 21 can move above the entrance of the third channel 123 to prevent the tobacco material from entering the third channel 123.

[0044] In some embodiments of this utility model, the feeding channel 11 includes two side plates spaced apart in its width direction. The side plates are provided with strip-shaped perforations 111 extending along the length direction of the feeding channel 11. The two ends of the distributing roller 21 are rotatably mounted in the two strip-shaped perforations 111 through connecting shafts 23. The position adjustment mechanism 3 can drive the distributing roller 21 to move in the strip-shaped perforations 111 and can position the distributing roller 21. The first drive motor 22 is connected to one of the connecting shafts 23 to drive the distributing roller 21 to rotate.

[0045] Specifically, when it is necessary to adjust the position of the distributing roller 21, the position adjustment mechanism 3 drives the distributing roller 21 to move in the strip-shaped perforation 111; and when the distributing roller 21 moves to the target position, the position adjustment mechanism 3 can position the distributing roller 21 in the strip-shaped perforation 111.

[0046] like Figure 3 As shown, in some embodiments of this utility model, the position adjustment mechanism 3 includes a material roller driving mechanism 34 and a guide mechanism 31. The guide mechanism 31 is installed on the outer side of the side plate of the feeding channel 11. The connecting shaft 23 of the material distribution roller 21 is installed on the guide mechanism 31. The material roller driving mechanism 34 is connected to the guide mechanism 31 and can drive the material distribution roller 21 to move linearly in the strip-shaped perforation 111 through the guide mechanism 31.

[0047] Specifically, the connecting shaft 23 of the distributing roller 21 is mounted on the guide mechanism 31, and the distributing roller 21 can rotate relative to the guide mechanism 31. The roller drive mechanism 34 can drive the distributing roller 21 to move linearly in the strip-shaped perforation 111 through the guide mechanism 31 to adjust the position of the distributing roller 21. Furthermore, the movement of the distributing roller 21 does not affect its rotation, so it is not necessary to completely shut down the first drive motor 22 when adjusting the position of the distributing roller 21.

[0048] In some embodiments of this utility model, the guiding mechanism 31 includes a connecting plate 32, two sliders and two guide rails 33. The two guide rails 33 are respectively installed on the upper and lower sides of the strip-shaped through hole 111. The guide rails 33 extend along the length direction of the feeding channel 11. The connecting plate 32 is slidably connected to the two guide rails 33 by the two sliders respectively. A connecting shaft 23 of the distributing roller 21 passes through the middle of the connecting plate 32 and is rotatably connected to the connecting plate 32.

[0049] Specifically, the material roller drive mechanism 34 is connected to the connecting plate 32 and can drive the connecting plate 32 to move linearly on the guide rail 33 to adjust the position of the material distribution roller 21.

[0050] In some embodiments of this utility model, there are two guide mechanisms 31, which are respectively installed on the two side plates of the feeding channel 11 to enhance the stability of the material distribution roller 21 during the position adjustment process. The material roller driving mechanism 34 can drive the two connecting plates 32 to move along their corresponding guide rails 33.

[0051] In some embodiments of this utility model, the material roller drive mechanism 34 includes two lead screws 38, a transmission chain 35, and a second drive motor 37. The two lead screws 38 correspond to two connecting plates 32 respectively. The two ends of the lead screws 38 are rotatably mounted on the side plates. The lead screws 38 extend along the length direction of the feed channel 11. Nuts are threaded on the lead screws 38, and the nuts are fixedly connected to the corresponding connecting plates 32. The second drive motor 37 is fixedly connected to the end of one of the lead screws 38. The ends of the two lead screws 38 are connected by the transmission chain 35 to achieve synchronous rotation.

[0052] Specifically, the transmission chain 35 connects the two lead screws 38 via gears, so that the second drive motor 37 drives the two lead screws 38 to rotate synchronously. The connecting plate 32, which is fitted with a nut on the lead screw 38, moves on the guide rail 33 due to the rotation of the lead screw 38, thereby driving the material distribution roller 21 to move.

[0053] In some embodiments of this utility model, the outer peripheral surface of the dispensing roller 21 is provided with grooves distributed in multiple rows and columns to increase the friction between the outer peripheral surface of the dispensing roller 21 and the tobacco material.

[0054] The tobacco dispensing device is also equipped with a controller, which is connected to the first drive motor 22, the second drive motor 37, and the two rotary drives 43 to control their operation. A position sensor 36 is provided on the side plate of the feeding channel 11. The position sensor 36 is located above the strip-shaped perforation 111 and can monitor the position and movement distance of the connecting shaft 23 of the dispensing roller 21. The position sensor 36 is connected to the controller.

[0055] Specifically, the controller imports data on the correspondence between the position, direction, and speed of the dispensing roller 21 and the falling range of the tobacco material. Based on this correspondence data and the monitoring information from the position sensor 36, the controller can control the operation of the first drive motor 22, the second drive motor 37, and the two rotary drives 43 to achieve the expected dispensing effect.

[0056] Another aspect of this utility model provides a tobacco material conveying device, which includes the tobacco dispensing device in the above embodiments.

[0057] Specifically, the tobacco material conveying equipment adopts the tobacco dispensing device of the above embodiment, so it can also achieve the above technical effects.

[0058] The operation process of the tobacco dispensing device of this utility model will be illustrated by the following examples 1-7.

[0059] Example 1

[0060] like Figure 4 As shown, when the tobacco material exits only from the first channel 121, the second distribution plate 42 closes the entrance to the second channel 122. At this time, the bottom side of the second distribution plate 42 is close to the junction of the first channel 121 and the second channel 122. The distribution roller 21 can be slightly moved to the left to prevent the distribution roller 21 from blocking the tobacco material from entering the first channel 121. The distribution roller 21 rotates clockwise at a high speed A1 (for example, the speed range of A1 can be 245 r / min - 273 r / min), causing the tobacco material to fall onto the distribution roller 21 and be thrown into the first channel 121. During this process, the second distribution plate 42 closes the entrance to the second channel 122 to prevent some tobacco material from entering the second channel 122.

[0061] Example 2

[0062] like Figure 5 As shown, when the tobacco material exits only from the second channel 122, the first dividing plate 41 closes the first channel 121, and the second dividing plate 42 opens the second channel 122. The bottom side of the second dividing plate 42 is close to the junction of the second channel 122 and the third channel 123. The dividing roller 21 is moved to the left and positioned above the left side of the second channel 122 to prevent it from blocking the tobacco material from entering the second channel 122. The dividing roller 21 rotates clockwise at a low speed A2 (for example, the speed range of A2 can be 109 r / min - 136 r / min). At this time, the distance the tobacco material is thrown out is shorter than the distance it is thrown out when the dividing roller 21 rotates at a high speed A1, thus causing the tobacco material to fall into the second channel 122.

[0063] It should be noted that in Embodiments 1 and 2, since the tobacco material is thrown downwards in the direction towards the front plate 112 after contacting the dispensing roller 21, no tobacco material will enter the third channel 123.

[0064] Example 3

[0065] like Figure 6 As shown, when the tobacco material exits only from the third channel 123, the first dividing plate 41 closes the first channel 121, and the second dividing plate 42 closes the second channel 122. At this time, the bottom side of the second dividing plate 42 is close to the junction of the first channel 121 and the second channel 122. The dividing roller 21 moves to the right so that the space above the third channel 123 is not obstructed. The dividing roller 21 rotates counterclockwise at a high speed A1 (for example, the speed range of A1 can be 245 r / min - 273 r / min). The tobacco material is thrown out after encountering the dividing roller 21 and then falls into the third channel 123.

[0066] Example 4

[0067] like Figure 7 As shown, when the tobacco material exits from the first channel 121 and the third channel 123, the first dividing plate 41 opens the first channel 121, and the second dividing plate 42 closes the second channel 122. The dividing roller 21 moves slightly to the right, positioning itself above the second dividing plate 42. The dividing roller 21 rotates counterclockwise at a high speed A1 (for example, the speed range of A1 can be 245 r / min - 273 r / min). A portion of the tobacco material is thrown into the third channel 123 by the dividing roller 21, while another portion is guided into the first channel 121 as the dividing roller 21 rotates.

[0068] Example 5

[0069] like Figure 8 As shown, when the tobacco material exits from the second channel 122 and the third channel 123, the first dividing plate 41 closes the first channel 121, and the second dividing plate 42 opens the second channel 122. The bottom side of the second dividing plate 42 is close to the junction of the second channel 122 and the third channel 123. The dividing roller 21 remains stationary in the middle position of the strip-shaped perforation 111, that is, the dividing roller 21 is positioned above the extension line of the second dividing plate 42. The dividing roller 21 rotates counterclockwise at a medium-high speed A5 or A3 (for example, the speed range of A3 can be 204 r / min - 245 r / min, and the speed range of A5 can be 163 r / min - 204 r / min). A portion of the tobacco material is thrown downwards into the third channel 123 by the dividing roller 21, and another portion of the tobacco material is guided into the second channel 122 as the dividing roller 21 rotates. It should be noted that in this embodiment, the distance the tobacco material is thrown is shorter than the distance it is thrown when the dividing roller 21 rotates at a high speed A1.

[0070] Example 6

[0071] like Figure 9 As shown, when the tobacco material exits from the first channel 121 and the second channel 122, the first channel 121 opens and the second channel 122 closes. The distributing roller 21 moves to the right and is positioned above the space between the first channel 121 and the second channel 122. The distributing roller 21 rotates counterclockwise at a low speed A2 (for example, the speed range of A2 can be 109 r / min - 136 r / min). Some of the tobacco material moves along with the rotation of the distributing roller 21, and this portion of tobacco material falls into the second channel 122 under the action of gravity. Another portion of the tobacco material falls from the space between the distributing roller 21 and the front plate 112 into the first channel 121.

[0072] Example 7

[0073] like Figure 10 As shown, when the tobacco material is discharged from the first channel 121, the second channel 122, and the third channel 123, the first channel 121 opens, and the second distribution plate 42 opens. The distribution roller 21 moves above the second channel 122 and rotates counterclockwise at a speed of A4 or A5 (for example, the speed range of A4 can be 136 r / min - 163 r / min, and the speed range of A5 can be 163 r / min - 204 r / min). A portion of the tobacco material falling onto the distribution roller 21 is thrown downwards into the third channel 123 by the distribution roller 21, and the remaining tobacco material is guided by the distribution roller 21 into the first channel 121 and the second channel 122 (same as in Embodiment 6).

[0074] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0075] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0076] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
