[0042] Such as Figures 1 - 6As shown in the figure, in this embodiment, the device for evenly packing tobacco leaves in a tobacco industry humidifying machine includes a bracket 1, a driving mechanism 2, a smoke baffle 3, a scraper 4, and a detection component. Among them, the bracket 1 is erected on the conveying roller path 100, the driving mechanism 2 is arranged on the bracket 1, the smoke baffle 3 can be located between the mesh box 200 on the conveying roller path 100 and the discharge opening of the electronic belt scale 300, and the smoke baffle 3 is arranged on the driving mechanism 2. The smoke baffle 3 can slide relative to the bracket 1 under the action of the driving mechanism 2 to open or block the opening of the mesh box 200. The smoke baffle 3 is used to temporarily store the tobacco leaf material conveyed by the electronic belt scale 300 to the mesh box 200. The scraper 4 is arranged on the bracket 1 and is in contact with the smoke baffle 3. The scraper 4 is used to scrape the tobacco leaf material on the smoke baffle 3 into the empty mesh box 200. The detection component includes a first sensor and a control circuit board electrically connected to the first sensor. The first sensor is installed on the conveying roller path 100 and is used to detect the weight of the mesh box 200 on the conveying roller path 100. The control circuit board is used to control the opening or closing of the driving mechanism 2. Specifically, the tobacco leaf material is evenly conveyed by the electronic belt scale 300 into the mesh box 200 on the conveying roller path 100. After the mesh box 200 is packed, it is conveyed by the conveying roller path 100 to the vacuum backtracking process, and the next mesh box 200 repeats the above steps. The bracket 1 is erected on the conveying roller path 100, the smoke baffle 3 is arranged at the driving end of the driving mechanism 2, and the smoke baffle 3 is located between the discharge opening of the electronic belt scale 300 and the opening of the mesh box 200. When the mesh box 200 has just been packed, the smoke baffle 3 is used to temporarily store the tobacco leaf material falling from the discharge opening. The scraper 4 can slide and cooperate under the action of the driving mechanism 2 to scrape the tobacco leaf material temporarily stored on the smoke baffle 3 into the next mesh box 200. The first sensor is set as a weighing sensor and is installed on the conveying roller path 100. The driving mechanism 2 is controlled to open or close by detecting the weight of the mesh box 200.

[0043] The working principle of the device for evenly packing tobacco leaves in a tobacco industry humidifying machine is as follows: Multiple wire mesh boxes 200 are successively conveyed to the lower part of the discharge opening of the electronic belt scale 300 through the conveying roller path 100 for packing tobacco leaf materials. In the initial state, the opening of the wire mesh box 200 located below the discharge opening is in an open state, that is, the smoke baffle 3 does not block the opening of the wire mesh box 200. Then, the electronic belt scale 300 drops a fixed weight of tobacco leaf materials into the wire mesh box 200 through the discharge opening. When the first sensor detects that the weight of the wire mesh box 200 reaches the set value, which is the sum of the weight of the wire mesh box 200 itself and the weight of the tobacco leaf materials, the packing of the tobacco leaf materials in the wire mesh box 200 is completed. The first sensor sends a high level to the control circuit board, and the control circuit board can control the driving mechanism 2 to open. The driving mechanism 2 drives the smoke baffle 3 to block the opening of the wire mesh box 200. When the smoke baffle 3 is between the discharge opening and the opening of the wire mesh box 200, the first sensor sends a low level to the control circuit board, and the control circuit board can control the driving mechanism 2 to close, and the smoke baffle 3 stops moving. Although the electronic belt scale 300 stops working, the tobacco leaf materials with acceleration continue to fall at the end discharge opening of the electronic belt scale 300 under the action of inertia. At this time, the falling tobacco leaf materials will fall on the smoke baffle 3. The packed wire mesh box 200 is transported to the next process through the conveying roller path 100. At the same time, the next empty wire mesh box 200 is transported to directly below the discharge opening through the conveying roller path 100. At this time, when the first sensor detects that the weight of the wire mesh box 200 is its own weight, the first sensor sends a high level to the control circuit board, and the control circuit board can control the driving mechanism 2 to open. The driving mechanism 2 drives the smoke baffle 3 to move in a direction gradually away from the discharge opening. During the movement of the smoke baffle 3, the scraping plate 4 fits with the smoke baffle 3, and the scraping plate 4 slides relative to the smoke baffle 3, so that the tobacco leaf materials temporarily stored on the smoke baffle 3 are scraped into the empty wire mesh box 200. At the same time, the electronic belt scale 300 drops the tobacco leaf materials into the wire mesh box 200 through the discharge opening. When the smoke baffle 3 returns to the initial position, the first sensor sends a low level to the control circuit board, and the control circuit board can control the driving mechanism 2 to close, and the smoke baffle 3 stops moving. When the first sensor detects that the weight of the wire mesh box 200 reaches the set value, the first sensor sends a high level to the control circuit board, and the control circuit board can control the driving mechanism 2 to open. The driving mechanism 2 drives the smoke baffle 3 to block the opening of the wire mesh box 200. The device for evenly packing tobacco leaf materials in a tobacco industry humidifying machine does not need to transform the original equipment and achieves the effect of assisting in packing. Through the mutual cooperation of the smoke baffle 3 and the scraping plate 4, it is ensured that the weight of the tobacco leaf materials in each wire mesh box 200 is consistent. At the same time, it is avoided that the tobacco leaf materials broken and fallen at the discharge opening after each packing fall on other equipment such as the conveying roller path 100, avoiding environmental pollution. Moreover, this part of the tobacco leaf materials can be scraped into the next wire mesh box 200 to avoid material waste.

[0044] Further, continue to refer to Figures 1 - 6, the driving mechanism 2 includes a first motor, a first lead screw 21 and a slider 22. The first motor is arranged on the bracket 1, the output end of the first motor is connected to the first lead screw 21, the slider 22 is in transmission connection with the first lead screw 21, and the slider 22 is connected to the smoke baffle 3. The smoke baffle 3 can slide along the length direction of the first lead screw 21 under the action of the first motor. Specifically, the first motor is in communication connection with the control circuit board. When the control circuit board sends a start signal to the first motor, the first motor rotates, the first lead screw 21 connected to the output end of the first motor rotates, the slider 22 is sleeved on the first lead screw 21, and the slider 22 is in threaded cooperation with the first lead screw 21, converting the rotational motion of the first lead screw 21 into a linear motion of the slider 22 along its axis. The slider 22 drives the smoke baffle 3 to slide to open or block the opening of the net box 200.

[0045] Further, continue to refer to Figures 1 - 6 , the tobacco leaf material uniform boxing device for the tobacco industry rehumidifier further includes a surrounding baffle 5. The surrounding baffle 5 includes a first surrounding part 51, a second surrounding part 52 and an intermediate surrounding part 53 connecting the first surrounding part 51 and the second surrounding part 52. The first surrounding part 51 and the second surrounding part 52 are arranged at intervals on both sides of the smoke baffle 3, and the intermediate surrounding part 53 is arranged at one end of the smoke baffle 3 away from the feeding port of the electronic belt scale 300. Specifically, the first surrounding part 51, the intermediate surrounding part 53 and the second surrounding part 52 are sequentially connected and enclosed into a U-shaped structure, ensuring that the tobacco leaf material on the smoke baffle 3 will not spill and can only be scraped into the net box 200 through the opening of the U-shaped surrounding baffle 5 by the scraper 4.

[0046] Further, continue to refer to Figures 1 - 6 , the scraper 4 includes a fixing part 41 and a scraping part 42. The fixing part 41 is arranged on the bracket 1 and is erected above the smoke baffle 3. The scraping part 42 is connected to the fixing part 41 and is in contact with the smoke baffle 3. The scraping part 42 is in a U-shaped structure. Specifically, the scraping part 42 slides and fits above the smoke baffle 3 through the fixing part 41. The U-shaped scraping part 42 can collect the tobacco leaf material on the smoke baffle 3 to the middle and scrape it all into the net box 200, preventing the tobacco leaf material on the smoke baffle 3 from spilling outside the net box 200.

[0047] Further, continue to refer to Figures 1 - 6, the support 1 includes a first support 11 and a second support 12. The first support 11 and the second support 12 are arranged in parallel. There are two conveying roller paths 100, and the two conveying roller paths 100 are arranged in parallel. The first support 11 and the second support 12 are respectively erected on the two conveying roller paths 100. Specifically, a single conveying roller path 100 transports the net box 200 longitudinally, and the two parallel conveying roller paths 100 are used to transport the net box 200 transversely. By clamping the two conveying roller paths 100 with the first support 11 and the second support 12 respectively, and through the mutual cooperation of the smoke baffle 3 and the scraper 4, multiple net boxes 200 are packed in sequence. The device for evenly packing tobacco leaf materials in a tobacco industry humidifying machine does not need to transform the original equipment, so as to achieve the effect of assisting in packing. Moreover, the support 1 is convenient for the installation of sensors, control circuit boards and actuators, and does not hinder the transportation of the net box 200.

[0048] Furthermore, continue to refer to Figures 1 - 6 , the device for evenly packing tobacco leaf materials in a tobacco industry humidifying machine further includes a material guiding mechanism 6. The material guiding mechanism 6 is located below the discharging opening of the electronic belt weigher 300, and the material guiding mechanism 6 is slidably arranged on the support 1 and is used for the tobacco leaf materials falling loosely. Specifically, the material guiding mechanism 6 includes a material guiding roller 61, a second motor and a second lead screw 62. The second motor is arranged on the support 1, the output end of the second motor is connected to the second lead screw 62, the axis direction of the material guiding roller 61 is perpendicular to the vertical direction of the falling tobacco leaf materials, the material guiding roller 61 is in transmission connection with the second lead screw 62, the material guiding roller 61 is slidably located below the discharging opening of the electronic belt weigher 300, and the material guiding roller 61 can slide along the length direction of the second lead screw 62 under the action of the second motor. The second motor is in communication connection with the control circuit board. When the control circuit board sends a signal to the second motor, the second motor rotates, the second lead screw 62 connected to the output end of the second motor rotates, one end of the material guiding roller 61 is sleeved on the second lead screw 62 and is in threaded cooperation with the first lead screw 21, converting the rotational motion of the second lead screw 62 into the linear motion of the material guiding roller 61 along the axial direction of the second lead screw 62. The material guiding roller 61 reciprocally slides above the opening of the net box 200 to loosen the falling tobacco leaf materials.

[0049] Furthermore, continue to refer to Figures 1 - 6 , there are multiple material guiding mechanisms 6, and the multiple material guiding mechanisms 6 are arranged at intervals along their sliding directions. Specifically, in order to further impact and loosen all the falling tobacco leaf materials, multiple material guiding rollers 61 are slidably arranged above the opening of the net box 200. The multiple material guiding rollers 61 reciprocally slide and the area swept by the sliding can cover the opening of the net box 200, so that all the falling tobacco leaf materials can be evenly scattered by the material guiding rollers 61, and the uniformity of the tobacco leaf materials after packing is good.

[0050] Furthermore, continue to refer to Figures 1 - 6, the tobacco leaf material uniform packing device for the tobacco industry rehumidifier further includes a second sensor, which is arranged at the bottom of the smoke baffle 3 and electrically connected to the control circuit board. The second sensor is used to detect whether there is tobacco leaf material in the mesh box 200. Specifically, when the empty mesh box 200 is transported to the lower part of the feeding port through the conveying roller path 100, the second sensor detects that there is no tobacco leaf material in the mesh box 200 and sends a high level to the control circuit board. The control circuit board can control the driving mechanism 2 to drive the smoke baffle 3 to open the opening of the mesh box 200. At the same time, the control circuit board is communicatively connected to the material guiding mechanism 6, and the control circuit board can control the material guiding mechanism 6 to slide relative to the bracket 1 at the opening of the mesh box 200 to loosen the falling tobacco leaf material, so that the packed tobacco leaf material is loose and uniform. When the second sensor detects that there is tobacco leaf material in the mesh box 200 and the first sensor detects that the weight of the mesh box 200 reaches the set value, that is, the mesh box 200 completes the packing of the tobacco leaf material, the control circuit board can control the material guiding mechanism 6 to stop sliding.
