[0028] Techniques, methods, and systems known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0029] Example 1: As Figure 1 The illustration shows only one embodiment of the present invention. A tobacco material uniform dispersion device includes a feeding section 1, a conveying section 2 disposed below the feeding section 1, and a blower section disposed between the feeding section 1 and the conveying section 2. The feeding section 1 includes a feeding trough 11 and a vibrator 12 for driving the feeding trough 11 to vibrate. The conveying section 2 includes a first conveyor belt 21 disposed below the feeding trough 11 and a second conveyor belt 22 disposed below the first conveyor belt 21. The conveying speed of the first conveyor belt 21 is less than the conveying speed of the second conveyor belt 22. The blower section includes a fan disposed between the feeding trough 11 and the first conveyor belt 21 and a controller electrically connected to the fan.

[0030] In this invention, the tobacco material 5 first enters the feeding section 1, then enters the conveying section 2, and finally exits to obtain the dispersed tobacco material. Specifically, the tobacco material is conveyed from the feeding trough 11 of the feeding section 1 to the conveying section 2, and passes through the blower at the end of the feeding trough 11 to reach the conveying section 2. The conveying section 2 includes a first conveyor belt 21 and a second conveyor belt 22 located below the first conveyor belt 21. That is, the tobacco material falling from the end of the feeding trough 11 first reaches the first conveyor belt 21, and then falls from the end of the first conveyor belt 21 onto the second conveyor belt 22.

[0031] Here, the air blowing part comprises a fan arranged between the feeding groove 11 and the first conveying belt 21 and a controller electrically connected with the fan, actually, the air outlet of the fan is arranged between the feeding groove 11 and the first conveying belt 21, the fan can be arranged at any sufficient space and is communicated with the air outlet through an air outlet pipe, in addition, the controller can control the start and stop of the fan and can control the air volume of the air outlet of the fan.

[0032] Since the dispersing device in the utility model can disperse various types of tobacco materials, the fan is a variable speed fan with large specifications, and is preferably arranged below the feeding part 1 and has the air outlet arranged between the feeding groove 11 and the first conveying belt 21, so that the fan is convenient to maintain and check.

[0033] In this way, the fan is used to blow air to the tobacco materials to achieve the first dispersing effect, and the dispersing effect is better.

[0034] Of course, in order to further improve the air blowing dispersing effect, the utility model also arranges a vibrator 12 for driving the feeding groove 11 to vibrate below the feeding groove 11, so that the feeding groove 11 is vibrated and spread, thereby preliminarily spreading and dispersing the tobacco materials 5 passing through the feeding groove 11, and then the tobacco materials 5 can be fully dispersed by the air blowing of the air outlet when reaching the end of the feeding groove 11.

[0035] In addition, the conveying part 2 comprises a conveying belt 21 and a driving roller 22 for driving the conveying belt 21 to convey, and the conveying belt 21 has sufficient area to catch the tobacco materials 5 blown by the air blower and convey the tobacco materials.

[0036] In addition, the conveying speed of the first conveying belt 21 is less than the conveying speed of the second conveying belt 22, so that the tobacco materials fall from the first conveying belt 21 to the second conveying belt 22 again and are thinned by differential speed, thereby completing the uniform spreading process of the final materials.

[0037] In summary, in the utility model, the tobacco materials are first loosened and spread in the feeding groove by the vibrator, then the tobacco materials at the end of the feeding groove are blown by the fan and fall to the first conveying belt, and finally the tobacco materials fall from the first conveying belt to the second conveying belt with higher speed to be dispersed by differential speed, so that the tobacco materials are fully dispersed and can be dispersed for various tobacco pieces, tobacco stems and tobacco shreds, and the dispersing effect is effectively improved, and the utility model can be applied to high-precision visual identification.

[0038] Example two, as Figure 1 , 2As shown, only for one embodiment of the utility model, on the basis of embodiment one, a tobacco material uniform dispersion device in the utility model, the lower side of feeding groove 11 is connected with electrostatic generator 14;In addition, the lower side of feeding groove 11 is connected with electrostatic generator 14;Actually, the lower side of the end of feeding groove 11 is connected with electrostatic generator 14, electrostatic generator 14 is connected with feeding groove 11, and electrostatic generator 14 is connected with feeding groove 11, and the process of vibrating and making tobacco material spread is attached to tobacco material, so that tobacco material falls from feeding groove 11, and due to the electrostatic effect, tobacco material is separated in the air, and the dispersion effect is better, and tobacco material is finally uniformly dropped on the first conveying belt 21 under the action of gravity.

[0039] At the same time, the second conveying belt 22 is provided with a conductive strip 23, so that the second conveying belt 22 is a conductive structure, and the static electricity is released after the tobacco material falls on the second conveying belt 22, and the process of thinning and dispersion is completed.

[0040] It should be noted that the first conveying belt 21 is an insulating part, so that the tobacco material falling on the first conveying belt 21 still has static electricity, and when the tobacco material falls from the end of the first conveying belt 21 on the second conveying belt 22, it is still separated and dispersed by static electricity, so that the tobacco material is subjected to two times of differential dispersion by static electricity, and after the tobacco material falls on the second conveying belt 22, the static electricity is released, and the dispersion effect of the tobacco material is better.

[0041] Of course, the number of conductive strips 23 is at least one, and actually, a plurality of conductive strips 23 are arranged on the second conveying belt 22, so that the static electricity on the tobacco material is fully released.

[0042] In summary, the tobacco material in the utility model is subjected to four times of dispersion: first time: vibrating and spreading by vibrator 12;Second time: repulsion between tobacco materials due to static electricity;Third time: air dispersion of tobacco material with static electricity by fan blowing;Fourth time: differential dispersion of tobacco material with static electricity falling from the end of the first conveying belt 21 on the second conveying belt 22;The dispersion effect of the tobacco material subjected to four times of dispersion is better.

[0043] In addition, the first conveying belt 21 is connected with the first driving roller 211;The second conveying belt 22 is connected with the second driving roller 221, the first driving roller 211 is electrically connected with the first motor 212;The second driving roller 221 is electrically connected with the second motor 222.

[0044] Here, the first motor 212 and the second motor 222 are stepless speed change motors, which can control the two times of differential value of tobacco material falling.

[0045] Embodiment three, as Figure 1 ,2 As shown, this is only one embodiment of the present invention. Based on any of the above embodiments, the present invention provides a tobacco material uniform dispersion device, which further includes a dispersion chamber 4. The feeding part 1, the conveying part 2 and the blowing part are all disposed in the dispersion chamber 4. An operation screen 41 is provided on the side of the dispersion chamber 4.

[0046] Of course, both the vibrator 12 and the electrostatic generator 14 are electrically connected to the operation panel.

[0047] Example 4, as Figure 1 , 2 As shown, this is only one embodiment of the present invention. Based on any of the above embodiments, in the tobacco material uniform dispersion device of the present invention, the feeding trough 11 is provided with a feeding bin 13. The feeding bin 13 is a funnel-shaped structure that is larger at the top and smaller at the bottom, which can fully guide the tobacco material to the feeding trough 11.

[0048] Furthermore, the height of the end of the feed trough 11 near the feed bin 13 is not lower than the height of the end of the feed trough 11 near the transmission section 2, so that when the tobacco material is vibrated by the vibrator 12 in the feed trough 11, it is not only fully spread out, but can also be displaced and transmitted along the inclined surface of the feed trough 11 towards the transmission section 2 under vibration.

[0049] In this utility model, a baffle plate is provided in front of the fan. The baffle plate is located on the upper side of the first conveyor belt 21. The tobacco material will reach the baffle plate under the blowing of the fan, and then fall from the baffle plate onto the first conveyor belt 21 below the baffle plate. Of course, the baffle plate is a non-metallic part, or an insulating part, preferably a plastic part, to prevent the static electricity on the tobacco material from being released too early.

[0050] Here, the fan is tilted upwards, which means that the air outlet of the fan is tilted upwards away from the feed trough 11, so that the tobacco material is blown away from the end of the feed trough 11 by the airflow and blown towards the first conveyor belt 21. When hot, the end of the feed trough 11 is located between the air outlet of the fan and the baffle plate.

[0051] In utility models, there are many structural design methods for the conductive strip 23. It can be perpendicular to the transmission direction of the second transmission belt 22, such as... Figure 1 As shown; it can also be parallel to the transmission direction of the second transmission band 22, such as... Figure 2 As shown; it can also be set at an angle, but not shown in the figure; it only requires that the conductive strips 23 be distributed on the second conveyor belt 22 to release the static electricity of the tobacco material in time.

[0052] Finally, a recycling hopper 24 is provided on the lower side of the second conveyor belt 22.
