Description

Technical Field

[0001] This invention relates to the field of tobacco stem processing technology, and in particular to a tobacco stem combing device. Background Technology

[0002] Cutting tobacco stems into shreds and mixing them into tobacco shreds can improve the utilization rate of tobacco raw materials, reduce production costs, and achieve the goals of reducing consumption and improving the combustibility of cigarettes.

[0003] Traditional tobacco stem cutting mostly involves directly conveying the stems into a shredder via a conveyor. Since the tobacco stems enter the shredder in a naturally disordered state, they are not all cut on the same cross section. As a result, the cut stems vary greatly in shape and thickness, with inconsistent lengths and thicknesses. This not only affects the appearance and uniformity of the stems but also impacts subsequent processing. Poor uniformity of the stems in cigarette blending ultimately affects the quality of the cigarettes.

[0004] In existing technologies, most methods involve setting a blocking mechanism on the conveying mechanism. The blocking mechanism includes several protrusions. When the conveyor belt of the conveying device conveys the tobacco stems, the tobacco stems move relative to the protrusions. When the transverse tobacco stems abut against the protrusions, one end of the tobacco stem is blocked by the protrusions, while the other end continues to move. The tobacco stems then rotate from "transverse" to "vertical", thereby achieving the sorting of the tobacco stems.

[0005] However, in actual use, when there are many tobacco stems being transported, the tobacco stems are blocked by subsequent tobacco stems when the protrusion pushes them to rotate, thus causing a blockage in the transport. This requires manual cleaning and a reduction in the amount of tobacco stems being transported. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a tobacco stem combing device to solve the problem in the prior art that when combing tobacco stems by protrusions, the transport of a large number of tobacco stems can easily cause transport blockage.

[0007] The present invention solves the above-mentioned technical problems through the following technical means:

[0008] A tobacco stem sorting device includes a conveying mechanism, a blocking mechanism, and a stem-pulling mechanism. The blocking mechanism is fixedly installed inside the conveying mechanism, and the stem-pulling mechanism is located above the blocking mechanism. The stem-pulling mechanism includes a mounting shell, a rotating shaft, and multiple stem-pulling components. The mounting shell is fixedly installed on the conveying mechanism, and the rotating shaft is rotatably installed inside the mounting shell. A driving component is fixedly installed at one end of the mounting shell, and the driving component is kinetically connected to the rotating shaft. The multiple stem-pulling components are fixedly installed at equal intervals on the rotating shaft along its length. Each stem-pulling component includes a fixing ring and multiple stem-pulling parts, all of which are fixedly connected to the fixing ring. The fixing ring is fixedly connected to the rotating shaft. The blocking mechanism includes multiple blocking blocks, and when the rotating shaft drives the stem-pulling parts to rotate, the stem-pulling parts can pass between two adjacent blocking blocks.

[0009] Furthermore, the stem-pulling component includes a connecting rod and a stem-pulling rod. One end of the connecting rod is fixedly connected to a fixing ring, and the other end is rotatably connected to the stem-pulling rod. The stem-pulling rod is provided with a directional component. When the stem-pulling rod pulls the tobacco stem, the directional component makes the stem-pulling rod perpendicular to the conveying mechanism.

[0010] Furthermore, the lever includes two identical paddles, the top ends of which are rotatably mounted on both sides of the connecting rod. The directional assembly includes multiple first directional rods and multiple second directional rods. The same first directional rod is fixedly connected between two paddles of adjacent levers that are close to each other. A second directional rod is fixedly connected to the paddle near the end wall of the mounting housing. An annular groove is formed on the end wall inside the mounting housing, and the end of the second directional rod is slidably inserted into the annular groove.

[0011] Furthermore, the paddle includes a connecting part and a paddle lever part. The connecting part is rotatably connected to the connecting rod. The paddle lever part is provided with two rods. The connecting part has a sliding hole. The rods are slidably inserted into the sliding hole. A spring is sleeved on the rod. One end of the spring is fixedly connected to the connecting part, and the other end is fixedly connected to the paddle lever part.

[0012] Furthermore, annular strips are provided on both the inner and outer sides of the annular groove.

[0013] Furthermore, the top of one end of the multiple blocking blocks away from the lever mechanism is fixedly connected to the same horizontal plate, which is fixedly connected to the conveying mechanism.

[0014] Furthermore, the rotating shaft has several threaded holes, the fixing ring has multiple through holes, and a fixing bolt is installed in the through hole, with the end of the fixing bolt threaded into the threaded hole.

[0015] Furthermore, the conveying mechanism includes a conveyor belt and guard plates disposed on both sides of the conveyor belt. The two ends of the mounting shell are respectively fixedly connected to the two guard plates. The driving component is a drive motor, and the output shaft of the drive motor is fixedly connected to the rotating shaft.

[0016] Furthermore, the mounting shell includes a first plate and a second plate, the first plate and the second plate being fixedly connected to the guard plates on both sides of the conveyor belt, and a cover being fixedly installed between the first plate and the second plate.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention sets up a stem-pulling mechanism and a blocking mechanism in cooperation. The drive motor drives the stem-pulling mechanism to rotate in the direction of the conveying mechanism. The stem-pulling component moves the tobacco stem relative to the conveyor belt and makes the tobacco stem abut against the blocking block until one end of the tobacco stem is blocked by the blocking block, while the other end continues to move. The tobacco stem rotates from "horizontal" to "vertical", thus realizing the sorting of the tobacco stem. Since the stem-pulling mechanism moves the tobacco stem to the blocking block in advance, there is no need to worry about the tobacco stem being blocked by subsequent tobacco stems and unable to rotate, causing the problem of conveying blockage.

[0019] 2. By setting up a connecting rod, a stem-pulling rod, and a directional component, when the stem-pulling component rotates and the stem-pulling rod pulls the tobacco stem, the directional component makes the stem-pulling rod perpendicular to the conveying mechanism, thus avoiding the stem-pulling rod from tilting and coming into contact with the tobacco stem, which would cause the tobacco stem to be squeezed and unable to be pulled.

[0020] 3. The present invention slides the connecting part and the stem-pulling part together and provides thrust through a spring. When the stem-pulling part is in contact with the conveyor belt, the connecting rod can drive the connecting part to move, so that the connecting part moves relative to the stem-pulling part, while the stem-pulling part remains in contact with the conveyor belt and pokes the tobacco stems on the conveyor belt until the connecting rod drives the stem-pulling part to disengage from the conveyor belt, which effectively improves the stem-pulling effect of the stem-pulling part.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figures 1-3 As shown, a tobacco stem sorting device of the present invention includes a conveying mechanism, a blocking mechanism, and a stem-pulling mechanism. The blocking mechanism is fixedly installed inside the conveying mechanism, and the stem-pulling mechanism is located above the blocking mechanism. The conveying mechanism is used to convey tobacco stems. Specifically, the conveying mechanism includes a conveyor belt 11 and guard plates 12 disposed on both sides of the conveyor belt 11. The tobacco stems are located on the conveyor belt 11 and move in the same conveying direction as the conveyor belt 11. The guard plates 12 are disposed on both sides of the conveyor belt 11 by brackets to prevent the tobacco stems on the conveyor belt 11 from falling off the conveyor belt 11. It should be noted that the guard plates 12 do not move with the conveyor belt 11.

[0027] The stem-pulling mechanism is used to pull the tobacco stems on the conveyor belt 11. The blocking mechanism is used to cooperate with the stem-pulling mechanism to block the transverse tobacco stems pulled by the stem-pulling mechanism, so that the tobacco stems are rotated from "transverse" to "vertical" under the pull of the stem-pulling mechanism, thereby realizing the sorting of tobacco stems.

[0028] In this embodiment, the stem-picking mechanism includes a mounting shell 2, a rotating shaft 3, and multiple stem-picking components. The two ends of the mounting shell 2 are fixedly connected to two protective plates 12, respectively, so that the mounting shell 2 is fixedly installed on the conveying mechanism. The rotating shaft 3 is rotatably installed inside the mounting shell 2. Multiple stem-picking components are fixedly installed at equal intervals along the length of the rotating shaft 3. In use, the distance between adjacent stem-picking components can be set according to actual needs. It should be noted that, according to actual needs, multiple sets of stem-picking mechanisms and blocking mechanisms can be set on the same conveying mechanism. Along the conveying direction of the conveying mechanism, the gap between adjacent stem-picking components in the stem-picking mechanism gradually decreases, and the gap between adjacent blocking blocks 71 in the blocking mechanism gradually decreases, so as to comb tobacco stems of different lengths.

[0029] A drive component 4 is fixedly mounted on one end of the mounting housing 2. The drive component 4 is connected to the rotating shaft 3 via a transmission connection. In this embodiment, the drive component 4 is a drive motor, and the rotating shaft 3 of the drive motor is fixedly connected to the rotating shaft 3. When the drive motor is working, it drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the tobacco stem-pulling assembly to rotate. The tobacco stem-pulling assembly then moves the tobacco stems on the conveyor belt 11 toward the blocking mechanism. It should be noted that when the drive motor is working, the moving speed of the tobacco stem-pulling assembly must be greater than the conveying speed of the conveyor belt 11 so that the tobacco stem-pulling assembly can move the tobacco stems on the conveyor belt 11.

[0030] In this embodiment, the lever assembly includes a fixing ring 5 and multiple lever components 6. All lever components 6 are fixedly connected to the fixing ring 5, and are distributed at equal angles along the circumference of the fixing ring 5. The fixing ring 5 is fixedly connected to the rotating shaft 3. Specifically, the rotating shaft 3 has several threaded holes 31, and the fixing ring 5 has several through holes 51. Fixing bolts are installed in the through holes 51, and the ends of the fixing bolts are threaded into the threaded holes 31, thus achieving a fixed connection between the fixing ring 5 and the rotating shaft 3. It should be noted that the threaded holes 31 located at the same length position on the rotating shaft 3 form a group, and the threaded holes 31 on the rotating shaft 3 are divided into multiple groups. These multiple groups of threaded holes 31 are evenly spaced to adjust the installation position of the fixing ring 5. The blocking mechanism includes multiple blocking blocks 71. The top of the end of each blocking block 71 away from the lever mechanism is fixedly connected to the same horizontal plate 72, which is fixedly connected to the conveying mechanism. By setting the horizontal plate 72 to connect the multiple blocking blocks 71 together, it is convenient to fix the blocking blocks 71 between the two guard plates 12. It should be noted that a small gap is provided between the bottom of the blocking block 71 and the conveyor belt 11 to prevent the blocking block 71 from wearing down the conveyor belt 11. When the rotating shaft 3 drives the stem-pulling component 6 to rotate, the stem-pulling component 6 can pass between two adjacent blocking blocks 71. The stem-pulling component 6 pushes the tobacco stems on the conveyor belt 11 toward the blocking block 71 until the tobacco stems abut against the blocking block 71. One end of the tobacco stem is blocked by the blocking block 71, while the other end continues to move. The tobacco stems rotate from "horizontal" to "vertical", thus sorting the tobacco stems. Since the stem-pulling mechanism pushes the tobacco stems to the blocking block 71 in advance, there is no need to worry about the tobacco stems being blocked by subsequent tobacco stems, preventing them from rotating and causing conveyor blockage.

[0031] In this embodiment, the stem-pulling component 6 includes a connecting rod 61 and a stem-pulling rod 62. One end of the connecting rod 61 is integrally formed with the fixing ring 5, and the other end is rotatably connected to the stem-pulling rod 62. The stem-pulling rod 62 is provided with a directional component. When the stem-pulling rod 62 pokes the tobacco stem, the directional component makes the stem-pulling rod 62 perpendicular to the conveying mechanism, so as to avoid the stem-pulling rod 62 tilting and contacting the tobacco stem, which would cause the tobacco stem to be squeezed and unable to be poked.

[0032] Specifically, the lever 62 includes two identical lever pieces 621. The tops of the two lever pieces 621 are rotatably mounted on both sides of the connecting rod 61. The directional assembly includes multiple first directional rods 81 and multiple second directional rods 82. The lever pieces 621 of two adjacent levers 62 are fixedly connected to the same first directional rod 81. The lever piece 621 near the end wall of the mounting housing 2 is fixedly connected to the second directional rod 82. An annular groove 21 is formed on the end wall inside the mounting housing 2, and the end of the second directional rod 82 is slidably inserted into the annular groove 21. By setting the lever pieces 621 on both sides of the connecting rod 61, two adjacent levers 6 can be connected through the first connecting rod 61, so that the levers 62 of the levers 6 rotate synchronously. The annular groove 21 restricts the movement trajectory of the second directional rod 82, limiting the movement state of the lever piece 621 to a vertical state. This also prevents the lever 62 from being blocked by the corresponding connecting rod 61 when it rotates to the top, thus avoiding the situation where it cannot maintain a vertical state.

[0033] In this embodiment, annular strips 22 are provided on both the inner and outer sides of the annular groove 21, and the limiting effect of the annular groove 21 can be reinforced by the annular strips 22.

[0034] In this embodiment, the paddle 621 includes a connecting part 63 and a paddle part 64. The connecting part 63 is rotatably connected to the connecting rod 61. The paddle part 64 is provided with two rods 641. The connecting part 63 has a sliding hole, and the rods 641 are slidably inserted into the sliding hole. A spring 65 is sleeved on the rods 641. One end of the spring 65 is fixedly connected to the connecting part 63, and the other end is fixedly connected to the paddle part 64. When the paddle part 64 is in contact with the conveyor belt 11, the connecting rod 61 can drive the connecting part 63 to move, so that the connecting part 63 moves relative to the paddle part 64. The paddle part 64 remains in contact with the conveyor belt 11 and paddles the tobacco stems on the conveyor belt 11. That is, the paddle part 64 moves across the conveyor belt 11 in a relatively horizontal state, paddles the tobacco stems on the conveyor belt 11, until the connecting rod 61 drives the paddle part 64 to disengage from the conveyor belt 11, effectively improving the paddle effect of the paddle part 64.

[0035] In this embodiment, the mounting shell 2 includes a first plate 23 and a second plate 24. The first plate 23 and the second plate 24 are fixedly connected to the guard plates 12 on both sides of the conveyor belt 11. By setting the first plate 23 and the second plate 24, it is convenient to fix the mounting shell 2 on the guard plates 12. A cover 25 is fixedly installed between the first plate 23 and the second plate 24. In this embodiment, the cover 25 is a transparent cover, which makes it convenient for the staff to observe the internal tobacco stem combing.

[0036] The working principle of the tobacco stem combing device in this embodiment is as follows:

[0037] The conveying mechanism operates, with the conveyor belt 11 transporting the tobacco stems towards the stem-pulling mechanism. The drive motor operates, causing the rotating shaft 3 to rotate, which in turn drives the stem-pulling assembly to rotate. The rotational speed of the stem-pulling assembly is greater than the conveying speed of the conveyor belt 11.

[0038] During the rotation of the stem-pulling assembly, when the tobacco stem reaches the stem-pulling mechanism, the connecting rod 61 rotates, causing the pulling plate 621 to gradually move closer to the tobacco stem. When the stem-pulling part 64 connects with the conveyor belt 11, the connecting rod 61 can drive the connecting part 63 to move, causing the connecting part 63 to move relative to the stem-pulling part 64. The stem-pulling part 64 remains connected to the conveyor belt 11, pulling the tobacco stem on the conveyor belt 11. That is, the stem-pulling part 64 moves across the conveyor belt 11 in a relatively horizontal state, pulling the tobacco stem on the conveyor belt 11 and pushing the tobacco stem on the conveyor belt 11 towards the blocking block 71 until the tobacco stem abuts against the blocking block 71. One end of the tobacco stem is blocked by the blocking block 71, while the other end continues to move. The tobacco stem rotates from "horizontal" to "vertical". Subsequently, the connecting rod 61 drives the stem-pulling part 64 to disengage from the conveyor belt 11. The subsequent adjacent connecting rods 61 continue to repeat the upward movement step to achieve cyclic stem-pulling, continuously pushing the tobacco stem to the blocking block 71 for sorting.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
