Description

Technical Field

[0001] This utility model relates to the field of tobacco shred separation technology, and in particular to a tobacco shred separation system. Background Technology

[0002] During 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, the tobacco shreds are lifted from the silo and enter the feed hopper through the lifting mechanism. The tobacco shreds are then transported to the feeder by wind power, and the feeder transports the tobacco shreds through pipelines to the cigarette rolling equipment.

[0003] In the existing technology, the hopper is equipped with air ducts on both sides to adapt to changing the conveying direction of tobacco shreds. That is, it can convey tobacco shreds on one side or both sides to simultaneously serve two tobacco feeders. However, with two air ducts in the same hopper, when conveying on one side, the tobacco shreds may accidentally enter the air duct on the side that does not need to be conveyed due to the wind force. This not only wastes the tobacco shreds but also causes the air duct to become clogged, affecting the material distribution efficiency and effect of the hopper. Utility Model Content

[0004] The purpose of this utility model is to provide a tobacco shred sorting system to solve the problem in the prior art where two air ducts are set in the same hopper. When conveying on one side, the tobacco shreds will accidentally enter the air duct on the side that does not need to be conveyed due to the wind force. This not only wastes the tobacco shreds but also causes the air duct to be blocked. The system reduces the waste of tobacco shreds and improves the efficiency and effect of tobacco shred sorting.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] In the existing technology, the hopper is equipped with air ducts on both sides to adapt to changing the conveying direction of tobacco shreds. That is, it can convey tobacco shreds on one side or both sides to simultaneously serve two tobacco feeders. However, with two air ducts in the same hopper, when conveying on one side, the tobacco shreds may accidentally enter the air duct on the side that does not need to be conveyed due to the wind force. This not only wastes the tobacco shreds but also causes the air duct to become clogged, affecting the material distribution efficiency and effect of the hopper.

[0038] To address the aforementioned problems, this embodiment provides a tobacco shred dispensing system, see reference. Figure 1 and Figure 2 The tobacco shred sorting system includes a hopper, a lifting mechanism, and a conveying mechanism 100.

[0039] Furthermore, the hopper is used to store tobacco shreds, and the lifting mechanism is used to lift the tobacco shreds in the hopper to a higher position. Specifically, the lifting mechanism includes three third conveyor belts, two of which are horizontally positioned and staggered vertically, and the third conveyor belt is inclined and connected to the two horizontally positioned third conveyor belts. The outlet of the hopper is located above the lower third conveyor belt. After the tobacco shreds fall onto this third conveyor belt, they are conveyed to a higher position by the inclined third conveyor belt and then discharged via the higher third conveyor belt. Specifically, a support member is provided at the bottom of the lifting mechanism to support it. In other embodiments, the third conveyor belt can also be a single conveyor belt, with a pressure roller installed at the angle between the horizontal and inclined directions of the third conveyor belt. It should be noted that since the hopper and lifting mechanism are prior art, their control structures and specific materials are not listed here.

[0040] Furthermore, the conveying mechanism 100 is disposed below the discharge end of the lifting mechanism for receiving and conveying tobacco shreds. The conveying mechanism 100 includes a first conveying component 110 and a second conveying component 120. The first conveying component 110 can convey tobacco shreds in a first direction, and the second conveying component 120 can convey tobacco shreds in a second direction, which are opposite to each other. The conveying mechanism 100 can move along the first and second directions to adjust the tobacco shreds falling into the first conveying component 110 and / or the second conveying component 120. By providing a movable conveying mechanism 100, when tobacco shreds need to be conveyed on one side, the first conveying component 110 or the second conveying component 120 can be moved below the discharge end of the lifting mechanism. When tobacco shreds need to be conveyed on both sides, both the first conveying component 110 and the second conveying component 120 can be located below the discharge end of the lifting mechanism, thereby reducing tobacco shred waste and improving the efficiency and effectiveness of tobacco shred distribution.

[0041] Specifically, the first conveying assembly 110 includes a first conveyor belt 111, a first driving roller 112, and a first driven roller 113. The first conveyor belt 111 is wound around the roller surfaces of the first driving roller 112 and the first driven roller 113. Rotation of the first driving roller 112 drives the first conveyor belt 111 to convey tobacco shreds along a first direction, and the first driven roller 113 is driven to rotate by the first conveyor belt 111. The second conveying assembly 120 includes a second conveyor belt 121, a second driving roller 122, and a second driven roller 123. The second conveyor belt 121 is wound around the roller surfaces of the second driving roller 122 and the second driven roller 123. Rotation of the second driving roller 122 drives the second conveyor belt 121 to convey tobacco shreds along a second direction, and the second driven roller 123 is driven to rotate by the second conveyor belt 121. Specifically, the belt surfaces of the first conveyor belt 111 and the second conveyor belt 121 are staggered in the vertical direction, and the projections of the central axes of the first driven roller 113 and the second driven roller 123 in the horizontal direction coincide. When the first driven roller 113 and the second driven roller 123 are aligned in the vertical direction, the ends of the first conveyor belt 111 and the second conveyor belt 121 will coincide in the horizontal direction, thus preventing the tobacco from falling through the gap between the first conveyor belt 111 and the second conveyor belt 121 when the tobacco is conveyed on both sides.

[0042] Furthermore, the first conveying assembly 110 and the second conveying assembly 120 also include a first tension adjusting roller 114 and a second tension adjusting roller 124, respectively. The first tension adjusting roller 114 is located between the two belt surfaces of the first conveyor belt 111, and the inner belt surface of the first conveyor belt 111 abuts against the surface of the first tension adjusting roller 114. The second tension adjusting roller 124 is located between the two belt surfaces of the second conveyor belt 121, and the inner belt surface of the second conveyor belt 121 abuts against the surface of the second tension adjusting roller 124. The first tension adjusting roller 114 and the second tension adjusting roller 124 are movable to adjust the tension of the first conveyor belt 111 and the second conveyor belt 121.

[0043] Specifically, the first conveying assembly 110 and the second conveying assembly 120 also include a plurality of auxiliary rollers 125. The auxiliary rollers 125 are located at the bottom of the first conveyor belt 111 and the second conveyor belt 121. The first tension adjusting roller 114 and the second tension adjusting roller 124 are located below the auxiliary rollers 125. The top edge of the auxiliary rollers 125 coincides with the bottom edge of the first driving roller 112, the first driven roller 113, the second driving roller 122, and the second driven roller 123. The first tension adjusting roller 114 and the second tension adjusting roller 124 can move horizontally to adjust the tension of the first conveyor belt 111 and the second conveyor belt 121. It should be noted that changing the position of the rollers includes sliding rail movement, telescopic rod driving, cylinder pushing, etc., all of which are existing technologies and will not be listed here.

[0044] Furthermore, the conveying mechanism 100 also includes a driving assembly, which includes a first driving member 131 and a second driving member 132. The first driving member 131 is disposed around the first active roller 112 to drive the first active roller 112 to rotate, and the second driving member 132 is disposed around the second active roller 122 to drive the second active roller 122 to rotate. In this embodiment, both the first driving member 131 and the second driving member 132 are AC motors. In other embodiments, the first driving member 131 and the second driving member 132 may be DC motors or stepper motors, and no limitation is made here.

[0045] Furthermore, the conveying mechanism 100 also includes a limiting component 140, which includes two first limiting plates 141 and two second limiting plates 142. The two first limiting plates 141 are respectively disposed on both sides of the first conveyor belt 111, and the two second limiting plates 142 are respectively disposed on both sides of the second conveyor belt 121. By setting the first limiting plates 141 and the second limiting plates 142, tobacco shreds are prevented from falling off the sides of the first conveyor belt 111 and the second conveyor belt 121 during conveying. In other embodiments, limiting nets or the like can be provided on both sides of the first conveyor belt 111 and the second conveyor belt 121.

[0046] Furthermore, the tobacco shred sorting system also includes a support frame 200 and a moving mechanism 300. The support frame 200 is located at the bottom of the conveying mechanism 100, and the moving mechanism 300 is located at the bottom of the support frame 200. The moving mechanism 300 can drive the support frame 200 to move along the first direction and the second direction, thereby driving the conveying mechanism 100 to move.

[0047] Specifically, the support frame 200 includes a support plate 210, a support rod 220, and a bottom support frame 230. The support plate 210 is disposed on both sides of the first conveyor belt 111 and the second conveyor belt 121. The first driving roller 112, the first driven roller 113, the second driving roller 122, the second driven roller 123, the first tension adjusting roller 114, the second tension adjusting roller 124, and the auxiliary roller 125 are all rotatably fixed to the support plate 210 at both ends. The first limiting plate 141 and the second limiting plate 142 are fixed to the upper part of the support plate 210. One end of the support rod 220 is connected to the support plate 210, and the other end is connected to the bottom support frame 230 to support the conveying mechanism 100. The moving mechanism 300 is disposed at the bottom of the bottom support frame 230. In this embodiment, the support rod 220 includes a support crossbar and two support vertical rods. The two support vertical rods are vertically connected to the two ends of the support crossbar to form a "concave" shape, and the ends of the support vertical rods are connected to the support plate 210.

[0048] Specifically, the moving mechanism 300 includes a guide member 310, a mating member 320, and a driving member 330. The guide member 310 extends along a first direction and a second direction. The mating member 320 mates with the guide member 310. The driving member 330 is disposed on the guide member 310 or the mating member 320 to drive the mating member 320 to move on the guide member 310. In this embodiment, the guide member 310 is configured as a slide rail, the mating member 320 is configured as a pulley, the pulley mates with the slide rail, and the driving member 330 is configured as an AC motor and disposed on the pulley.
