In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] The current dispersed feeding device lacks a protective device on the rotating shaft, which will cause tobacco and other materials to be entangled on the rotating shaft after a long period of operation. Excessive accumulation of material residues on the rotating shaft will cause the rotating shaft to fail to achieve the ideal working effect, and even cause the rotating shaft to get stuck and malfunction, thereby damaging the device.

[0036] In this regard, the present embodiment provides a material distributor, which can protect the rotating shaft, prevent the tobacco material from being entangled on the rotating shaft, and improve the service life of the material distributor; and the material distributor can also efficiently disperse tobacco and other materials, and can adjust the flow rate of tobacco and other materials. The material distributor can be used in laboratories and tobacco factories, etc., to achieve the functions of dispersing and conveying tobacco and other materials.

[0037] Please refer to Figures 1 to 4 As shown, the material mixer includes a hopper 1, a rotating shaft 2, a driving device 3, a protective sleeve 4, and a material distribution plate 5. A material storage cavity 11 is provided in the hopper 1, and a feed port 12 and a discharge port 13 are also provided on the hopper 1. The feed port 12 and the discharge port 13 are both connected to the material storage cavity 11, and the material can flow through the feed port 12, the material storage cavity 11, and the discharge port 13 in sequence; the rotating shaft 2 is arranged in the material storage cavity 11; the driving device 3 is connected to the rotating shaft 2 in a transmission manner, and the driving device 3 drives the rotating shaft 2 to rotate; the protective sleeve 4 is arranged in the material storage cavity 11, and the rotating shaft 2 is rotatably arranged in the protective sleeve 4, and the protective sleeve 4 is fixed on the hopper 1; the material distribution plate 5 is connected to the rotating shaft 2, and the rotating shaft 2 drives the material distribution plate 5 to rotate when the rotating shaft 2 rotates. The material distribution plate 5 is located below the discharge port 13, and the material flows through the material distribution plate 5, and the material distribution plate 5 is used to disperse the material flowing through.

[0038] Specifically, in the present embodiment, the material flows into the material holding cavity 11 from the feed port 12, and then the material flows downward along the inner wall of the hopper 1 and flows out from the discharge port 13; in the process of the material in the material holding cavity 11 flowing downward, the protective sleeve 4 is sleeved on the outer side of the rotating shaft 2, so that the material cannot be entangled on the rotating shaft 2, thereby realizing the protection of the rotating shaft 2, and the rotating shaft 2 is rotatably passed through the protective sleeve 4, so the rotating shaft 2 can rotate normally and continuously. The setting of the protective sleeve 4 protects the rotating shaft 2, thereby increasing the service life of the material mixer. After flowing out of the discharge port 13, the material falls onto the distribution plate 5, and the distribution plate 5 rotates to disperse the fallen material into a state that is easy to process. In the present embodiment, the driving device 3 is specifically a motor.

[0039] In other embodiments, the material distribution tray 5 may also be disposed above the discharge port 13 and located in the material holding cavity 11 , so that the material is first dispersed by the material distribution tray 5 and then flows out from the discharge port 13 .

[0040] Alternatively, if Figure 2 As shown, the material distribution plate 5 includes a plurality of material distribution pieces 51 and a sleeve 52, the sleeve 52 is connected to the plurality of material distribution pieces 51, the sleeve 52 is fixedly sleeved on the rotating shaft 2, and the plurality of material distribution pieces 51 are arranged at intervals on the outer peripheral surface of the sleeve 52. Specifically, in this embodiment, there are gaps between the adjacent material distribution pieces 51 on the sleeve 52, so that the dispersed materials can fall from the gaps under the action of gravity, thereby preventing the materials from accumulating on the material distribution plate 5.

[0041] Alternatively, if Figure 2 As shown, the cross section of the material dividing member 51 is a right triangle, the first right-angled side 511 of the right triangle is parallel to the axis of the rotating shaft 2, the second right-angled side 512 of the right triangle is perpendicular to the axis of the rotating shaft 2, and the hypotenuse 513 of the right triangle is inclined downward. Specifically, in this embodiment, the cross section of the material dividing member 51 is designed to be a right triangle, and the hypotenuse 513 of the right triangle is inclined downward. When the material dividing plate 5 rotates, a centrifugal force inclined downward is generated, which can better throw the material downward, which can effectively prevent the material from accumulating on the material dividing plate 5 and disperse the material through centrifugal force.

[0042] Alternatively, if Figure 2 As shown, the intersection of the second right-angled side 512 and the oblique side 513 is flush with or exceeds the edge of the discharge port 13. Specifically, in this embodiment, it is configured so that the outermost side of the projection of the distribution plate 5 in the vertical direction is flush with or exceeds the outermost side of the projection of the discharge port 13 in the vertical direction, thereby ensuring that the falling materials can be received by the distribution piece 51 of the distribution plate 5 and rotated to scatter.

[0043] Alternatively, if Figure 1 , Figure 3 , Figure 4 As shown, the material mixer also includes a hopper shell 6, which has a accommodating space 61. The hopper 1 is located in the accommodating space 61 and is connected to the hopper shell 6. The feed port 12 and the discharge port 13 are both connected to the accommodating space 61. The material distribution plate 5 is located in the accommodating space 61. The hopper shell 6 also has a first opening 62 and a second opening 63. The first opening 62 and the second opening 63 are both connected to the accommodating space 61. The first opening 62, the feed port 12, the discharge port 13, and the second opening 63 are arranged in sequence along the axial direction of the rotating shaft 2. Specifically, in this embodiment, a hopper shell 6 is further provided in the material leveler, and a accommodating space 61 is opened inside the hopper shell 6. The hopper 1 is located in the accommodating space 61 and is connected to the hopper shell 6, and the distribution plate 5 is also located in the accommodating space; the hopper shell 6 plays a role in protecting the hopper 1, the rotating shaft 2, the protective shaft sleeve 4 and the distribution plate 5, and preventing the external environment from affecting the hopper 1, the rotating shaft 2, the protective shaft sleeve 4 and the distribution plate 5.

[0044] Furthermore, the feed port 12 and the discharge port 13 are both connected to the accommodating space 61. Such an arrangement ensures that the material can flow smoothly between the feed port 12, the discharge port 13 and the accommodating space 61. The hopper shell 6 is also provided with a first opening 62 and a second opening 63. The first opening 62 and the second opening 63 are both connected to the accommodating space 61. Since the accommodating space 61 is also connected to the feed port 12 and the discharge port 13, the first opening 62, the second opening 63, the feed port 12 and the discharge port 13 are all connected. The first opening 62, the feed port 12, the discharge port 13 and the second opening 63 are arranged in sequence along the axial direction of the rotating shaft 2. The first opening 62 is at the top of the material refining machine. Therefore, the material flows through the first opening 62, the feed port 12, the material cavity 11, the discharge port 13 and the second opening 63 in sequence. When the material flows from the discharge port 13 to the second opening 63 , the material contacts the material distribution plate 5 and is dispersed by the material distribution plate 5 , and then flows out of the material distributor from the second opening 63 .

[0045] Due to the existence of the hopper shell 6, the entire process of material flow is protected by the hopper shell 6, which effectively avoids the external environment from interfering with the working process of the material mixer.

[0046] Alternatively, if Figure 1 , Figure 3 , Figure 4 As shown, a connecting seat 8 is also installed above the hopper shell 6. The connecting seat 8 is arranged along the axial direction of the rotating shaft 2. The connecting seat 8 and the hopper shell 6 are detachably connected, which is convenient for the subsequent disassembly and assembly of the connecting seat 8 on the hopper shell 6. The driving device 3 is detachably connected to the top of the connecting seat 8, and a bearing (not shown in the figure) is installed in the connecting seat 8. The rotating shaft 2 passes through the bearing and is connected to the output shaft of the driving device 3. The connecting seat 8 supports the rotating shaft 2. In this way, when the connecting seat 8 is disassembled above the hopper shell 6, the fasteners connecting the hopper shell 6 and the connecting seat 8 are removed, and the connecting seat 8 can be separated from the hopper shell 6; when the connecting seat 8 is disassembled, the driving device 3 and the rotating shaft 2 can be disassembled from the material leveler together, and the driving device 3 is subsequently disassembled from the connecting seat 8. When the driving device 3 is disassembled, the rotating shaft 2 is also disassembled from the connecting seat 8 together with the driving device 3. During installation, the driving device 3, the rotating shaft 2 and the connecting seat 8 can be conveniently and quickly installed in the material leveler by reverse operation. Disassembly and installation are convenient and quick.

[0047] Alternatively, if Figure 1As shown, the material leveler also includes an adjustment mechanism 7, which is used to adjust the relative position of the hopper shell 6 and the hopper 1 along the axial direction of the rotating shaft 2. Specifically, in this embodiment, the material distribution plate 5 is connected to the rotating shaft 2, and the rotating shaft 2 is indirectly fixedly connected to the hopper shell 6. When the relative position of the hopper shell 6 and the hopper 1 is adjusted, the material distribution plate 5, the rotating shaft 2 and the hopper shell 6 are all kept stationary, and the hopper 1 moves up and down along the axial direction of the rotating shaft 2, so that the distance between the discharge port 13 on the hopper 1 and the material distribution plate 5 changes with the adjustment of the adjustment mechanism 7. When the hopper 1 moves upward along the axial direction of the rotating shaft 2, the distance between the discharge port 13 and the material distribution plate 5 increases, and the flow rate of the material outflow increases accordingly; when the hopper 1 moves downward along the axial direction of the rotating shaft 2, the distance between the discharge port 13 and the material distribution plate 5 decreases, and the flow rate of the material outflow decreases accordingly. In this way, the distance between the discharge port 13 and the material distribution plate 5 is adjustable through the adjustment mechanism 7 to adjust the flow rate of the material outflow.

[0048] Alternatively, if Figure 1 As shown, there are multiple adjustment mechanisms 7, and the multiple adjustment mechanisms 7 are evenly distributed along the circumference of the rotating shaft 2. Specifically, in this embodiment, two adjustment mechanisms 7 are provided, and the two adjustment mechanisms 7 are evenly distributed along the circumference of the rotating shaft 2. The rotating shaft 2 is installed at the center of the material leveler, so the two adjustment mechanisms 7 are symmetrically arranged on both sides of the axis with the axis of the rotating shaft 2 as the symmetry center. In this way, by adjusting the two adjustment mechanisms 7 together, the hopper 1 will not be deflected to one side during the adjustment process, that is, the axis of the hopper 1 and the axis of the hopper shell 6 are in a coincident state, ensuring that the overall structure of the material leveler is in a better working state.

[0049] Alternatively, if Figure 1 As shown, the adjustment mechanism 7 includes a bolt 71 and an adjustment nut 72, the rotating shaft 2 is arranged in the vertical direction, the bolt 71 passes through the hopper housing 6 and the hopper 1 in sequence from top to bottom along the axial direction of the rotating shaft 2 and is screwed to the adjustment nut 72, and the adjustment nut 72 is located below the hopper 1 and abuts against the hopper 1. Specifically, in this embodiment, the adjustment mechanism 7 includes a bolt 71 and an adjustment nut 72, and the adjustment nut 72 and the bolt 71 are threadedly connected, so the adjustment nut 72 can rotate on the bolt 71. The adjustment nut 72 is below the hopper 1 and abuts against the hopper 1, and the movement of the hopper 1 on the bolt 71 can be driven by the rotation of the adjustment nut 72 on the bolt 71. Since the rotating shaft 2 is arranged in the vertical direction, the hopper 1 can move up in the vertical direction by rotating the adjustment nut 72 upward, and the hopper 1 can move down in the vertical direction by rotating the adjustment nut 72 downward and cooperating with gravity, thereby realizing the relative movement between the hopper 1 and the hopper housing 6.

[0050] Alternatively, if Figure 1As shown, the adjustment mechanism 7 further includes a first locking nut 73, the first locking nut 73 is threadedly connected to the bolt 71, the first locking nut 73 and the adjusting nut 72 are respectively located on both sides of the hopper 1 and both abut against the hopper 1, and / or the adjustment mechanism 7 further includes a second locking nut 74, the second locking nut 74 is threadedly connected to the bolt 71, the second locking nut 74 is located below the hopper shell 6 and is used to clamp the hopper shell 6 together with the head of the bolt 71. Specifically, in this embodiment, the first locking nut 73 is also threadedly connected to the bolt 71, and the first locking nut 73 can be rotated on the bolt 71; the first locking nut 73 and the adjusting nut 72 are respectively arranged on both sides of the hopper 1 and both abut against the hopper 1. In this way, the hopper 1 is fastened to the adjustment mechanism 7, and the relative shaking amount generated by the hopper 1 and the adjustment mechanism 7 during operation is reduced.

[0051] Or the adjustment mechanism 7 further includes a second locking nut 74, which is also threadedly connected to the bolt 71, and can be rotated on the bolt 71. The second locking nut 74 is arranged below the hopper shell 6 and abuts against the hopper shell 6; the bolt 71 passes through the hopper shell 6, and the head of the bolt 71 is above the hopper shell 6. The second locking nut 74 can clamp the hopper shell 6 together with the head of the bolt 71, and the tightness can be adjusted by rotating the second locking nut 74 on the bolt 71. The adjustment mechanism 7 is fastened to the hopper shell 6 by the cooperation of the bolt 71 and the second locking nut 74, reducing the relative shaking amount generated by the adjustment mechanism 7 and the hopper shell 6 during operation.

[0052] Furthermore, the adjustment mechanism 7 may also include a first locking nut 73 and a second locking nut 74, and the hopper 1 and the hopper housing 6 are indirectly fastened together through the first locking nut 73, the second locking nut 74, the adjustment nut 72 and the bolt 71. When the material mixer is working, the relative shaking between the hopper 1 and the hopper housing 6 is reduced, thereby increasing the service life of the material mixer.

[0053] Alternatively, if Figure 1 and Figure 3 As shown, the hopper 1 is in a conical shape, the feed port 12 is located at the large end of the hopper 1, and the discharge port 13 is located at the small end of the hopper 1. In this arrangement, the feed port 12 is a large port, which is conducive to the material entering the material holding cavity 11 from the feed port 12; the discharge port 13 is a small port, which is conducive to the material gathering along the inner wall of the hopper 1 to the discharge port 13, and then flowing out of the material holding cavity 11.

[0054] The present embodiment also provides a wire drying device, including a vibrating plate conveyor, a screw feeder, and the above-mentioned leveler. One end of the leveler is connected to the vibrating plate conveyor, and the other end of the leveler is connected to the screw feeder. Specifically, in the present embodiment, the upstream device of the leveler is the vibrating plate conveyor, and the upstream device is the screw feeder. The tobacco and other materials are fed into the leveler through the vibrating plate conveyor, and the tobacco and other materials are dispersed by the leveler before being fed into the downstream screw feeder. Since the tobacco and other materials are dispersed by the leveler, the tobacco and other materials in the entire wire drying device can be fully dried, thereby improving the quality of the tobacco and other materials. The wire drying device includes the leveler, and the service life of the leveler is improved, thereby improving the service life of the entire wire drying device.

[0055] Alternatively, if Figure 1 , Figure 3 , Figure 4 As shown, the material leveler also includes a flange 9, which is connected to the hopper housing 6, and the flange 9 is flush with the second opening 63. The flange 9 is provided with a plurality of connection holes, and the plurality of connection holes are spaced apart along the outer circumference of the second opening 63.
