[0018] Therefore, the present utility model provides the following effects and / or advantages:

[0019] 1. By adding the discharging mechanism in this application, the driving end of the pouring drive device drives the transverse moving member to move horizontally towards the pouring side, pushing the flipping member to slide horizontally. Then one end slides down along the flipping area, and the other end is restricted by the transverse moving member and flips towards the pouring side, so as to drive the pouring member to move horizontally and then flip to pour materials into the discharging device. Thus, it can realize the full-automatic and rapid discharging of the cut tobacco sample after sampling and weighing by the sampling and weighing mechanism, improve the discharging speed of the cut tobacco sample, avoid contaminating the cut tobacco sample during discharging, further improve the production efficiency of cigarette batching, ensure the production quality, and accelerate the product R & D speed.

[0020] 2. By adding the inversion area in this application, after the pouring member flips to the vertical position, it can be further flipped to an angle greater than ° with the top facing downwards, so as to realize the complete downward introduction of the cut tobacco contained in the pouring member into the discharging device, avoid the situation that there is cut tobacco residue in the pouring member during pouring, resulting in incorrect weight of the cut tobacco sample output by the discharging device, improve the integrity of pouring by the pouring device and the accuracy of discharging by the discharging device, and further ensure the stability and accuracy of discharging of the discharging mechanism.

[0021] 3. After the weighing pan is placed on the weighing device and sufficient tobacco leaves are weighed, the driving end of the blanking driving device moves horizontally along the lifting area and the driving groove to push the guide plate and the transverse moving member upward, so that the turning frame rises to connect with the weighing pan. The driving end of the blanking driving device continues to move horizontally to the limiting area and then abuts against the bottom of the driving groove, so that when the driving end of the blanking driving device continues to move horizontally, it pushes the transverse moving member to move horizontally, and further makes the transverse moving member push the turning member to move horizontally and then turn, driving the turning frame and the weighing pan to move horizontally and then turn over for blanking. Thus, after the blanking member drops and disengages from the weighing pan, the weighing function can be realized through the weighing pan. After the turning frame rises to connect with the weighing pan, the blanking function can be realized by driving the weighing pan to move horizontally and then turn over through the turning frame, realizing the rapid switching between the weighing step and the blanking step, improving the functionality of the blanking member, saving the redundant steps of moving the tobacco leaves from the weighing device to the blanking member, and further improving the blanking speed after the weighing of the tobacco leaf sample.

[0022] 4. After a receiving box has received the tobacco leaves output from the hopper, the turntable rotates until the guiding area where the receiving box is located is coaxial with the box conveyor belt, and the next receiving box is aligned with the lower end of the hopper to continue receiving materials. Subsequently, the telescopic end of the box-out cylinder retracts to drive the box-out push plate to push the receiving box to move horizontally to the box conveyor belt for positive rotation and discharging. Thus, on the premise of realizing the full-automatic discharging of the receiving box, through the setting of a number of receiving boxes, the next-level receiving box can be quickly supplemented for receiving materials, greatly saving the replacement interval of the receiving box, enabling the blanking device to continuously blank without stopping work, improving the fluency and continuity between the blanking step and the receiving step of the discharging mechanism, and further improving the discharging efficiency of the discharging mechanism.

[0023] 5. After a receiving box moves horizontally to the discharging position of the box conveyor belt and the next receiving box is aligned with the lower end of the hopper to continue receiving materials, first, a new receiving box is reversely input by the box conveyor belt to the end close to the turntable, and then the swing cylinder is used to push one end of the swing rod to swing around the rotation point, driving the box-in cylinder to swing to the position directly above the box conveyor belt and the box-in push plate to be located on the side of the new receiving box away from the turntable. Thus, through the extension of the telescopic end of the box-in cylinder, the new receiving box is pushed to be supplemented into the vacant guiding area. On the premise of realizing the full-automatic assembly of a number of receiving boxes into the corresponding guiding areas through the cooperation between the box conveyor belt and the box-in driving device, after a receiving box discharges materials, during the time when the next receiving box receives materials, a new receiving box can also be supplemented into the vacant guiding area through the cooperation between the box conveyor belt and the box-in driving device, improving the assembly efficiency of the receiving box and avoiding the interruption of receiving materials of the receiving box from affecting the discharging efficiency.

[0037] For the convenience of those skilled in the art to understand, the embodiments will now be further described in detail in conjunction with the accompanying drawings for the structure of the present utility model:

[0038] Refer to Figures 1-12 , a tobacco weighing device, comprising: a feeding mechanism, a sampling and weighing mechanism, and a discharging mechanism. The feeding mechanism is used to convey a storage box containing tobacco. The sampling and weighing mechanism is used to sample and weigh the tobacco in the storage box to form a tobacco sample. The discharging mechanism includes a tipping device 1 and a discharging device 2 distributed vertically. The discharging device 2 is used to receive and discharge materials;

[0039] The charging device 1 includes: a fixed seat 11, a guiding plate 12 provided on the fixed seat 11 and having a charging side 121 at one end, and a flipping member 13, a transverse moving member 14, and a charging member 15 for containing the cut tobacco sample located on the side of the guiding plate 12 away from the fixed seat 11. A guiding long hole 122 is provided through the guiding plate 12 and extends horizontally towards the charging side 121 and then extends obliquely downwards to form a flipping area 1211. The transverse moving member 14 is slidably connected to the guiding plate 12 horizontally. A charging driving device 16 for driving the transverse movement of the transverse moving member 14 is provided on the fixed seat 11. One end of the flipping member 13 is slidably disposed in the guiding long hole 122, and the other end rotatably penetrates through the transverse moving member 14 and is connected to the charging member 15. The driving end 161 of the charging driving device 16 drives the transverse moving member 14 to move horizontally towards the charging side 121, pushing the flipping member 13 to slide horizontally, and then one end slides down along the flipping area 1211, and the other end is restricted by the transverse moving member 14 and flips towards the charging side 121, so as to drive the charging member 15 to move horizontally and then flip to discharge the material into the discharging device 2. Specifically, the charging driving device 16 is a screw driving device, and its driving end 161 is disposed on the side and is driven to move left and right horizontally. In other embodiments, the charging driving device 16 can be set as other existing transverse movement driving devices, such as a cylinder, etc.

[0040] With the above structure, it is possible to realize the full-automatic and rapid charging and discharging of the cut tobacco sample after sampling and weighing by the cut tobacco weighing device, improve the discharging speed of the cut tobacco sample, avoid contaminating the cut tobacco sample during discharging, thereby improving the production efficiency of cigarette blending, ensuring the production quality, and accelerating the product R & D speed.

[0041] In order to further increase the flipping angle of the emptying member 15 and avoid incorrect weights of the cut tobacco output by the discharging device 2 due to cut tobacco residue, the end of the flipping area 1211 extends obliquely upward toward the emptying side 121 to form an inverted area 1222; when the traversing member 14 traverses toward the emptying side 121 and pushes one end of the flipping member 13 to slide down along the flipping area 1211 to between the flipping area 1211 and the inverted area 1222, the flipping member 13 and the emptying member 15 flip toward the emptying side 121 to the vertical. At this time, the emptying member 15 flips 90°. The traversing member 14 continues to traverse toward the emptying side 121 to pull one end of the flipping member 13 to slide up along the inverted area 1222, and the other end continues to flip toward the emptying side 121. The emptying member 15 continues to flip until the top faces downward. At this time, the emptying member 15 flips more than 90°. Thus, through the addition of the inverted area 1222, the emptying member 15 can be further flipped to a flipping angle greater than 90° with the top facing downward after flipping to the vertical, so as to empty all the cut tobacco contained in the emptying member 15 downward into the discharging device 2, avoid the situation of cut tobacco residue in the emptying member 15 during emptying, which may lead to incorrect weights of the cut tobacco samples output by the discharging device 2, and improve the integrity of emptying of the emptying device 1 and the accuracy of discharging of the discharging device 2, thereby ensuring the stability and accuracy of discharging of the discharging mechanism.

[0042] The tobacco weighing device includes a weighing device 73. In order to enable the pouring piece 15 to simultaneously combine the weighing function of weighing through the weighing device 73 and the pouring function after weighing, so as to realize the rapid switching between the weighing step and the pouring step, the guide plate 12 is penetrated with a limiting long hole 123 which extends laterally in the direction away from the pouring side 121 and then extends obliquely upward to form a lifting area 1231. The guide plate 12 is slidably connected to the fixed seat 11 up and down. Specifically, the guide plate 12 is slidably connected to the fixed seat 11 up and down through a slide rail and a slider. One end of the transverse moving piece 14 is recessed with a driving groove 141 adapted to the lifting area 1231. The driving end 161 is slidably penetrated in the limiting long hole 123 and the driving groove 141 in turn. The pouring piece 15 includes a piece filled with tobacco and used for weighing. The weighing plate 151 and the turning frame 152 connected to the turning piece 13 and located below the weighing plate 151 are detachably arranged; after the weighing plate 151 is placed on the weighing device 73 to receive a sufficient amount of tobacco for weighing, the driving end 161 moves laterally along the lifting area 1231 and the driving groove 141 to push the guide plate 12 and the transverse moving member 14 to rise, so that the turning frame 152 rises and connects to the weighing plate 151, and the driving end 161 continues to move laterally until it is separated from the lifting area 1231 and then abuts against the bottom of the driving groove 141, so that the driving end 161 pushes the transverse moving member 14 to move laterally when continuing to move laterally, and then the transverse moving member 14 pushes the turning piece 13 to move laterally and then flip, driving the turning frame 152 and the weighing plate 151 to move laterally and flip and dump the material. Thereby, after the tipping piece 15 is lowered and separated from the weighing plate 151 by the tipping frame 152, the weighing function can be realized through the weighing plate 151; after the tipping frame 152 is raised and connected to the weighing plate 151, the tipping function can be realized by driving the weighing plate 151 to move horizontally and then tip over by the tipping frame 152, thereby realizing rapid switching between the weighing step and the tipping step, improving the functionality of the tipping piece 15, saving redundant steps of moving the tobacco from the weighing device 73 to the tipping piece 15, and further improving the speed of tipping after the tobacco sample is weighed.

[0043] In order to facilitate the convenience of detachable connection between the weighing plate 151 and the flip frame 152, the outer wall of the weighing plate 151 extends outward to form a plurality of first magnetic attraction parts 1511, and the flip frame 152 is arranged in a square frame shape around the outer periphery of the weighing plate 151 and has a plurality of second magnetic attraction parts 1521 corresponding to the plurality of first magnetic attraction parts 1511 on the side. Specifically, the first magnetic attraction parts 1511 and the second magnetic attraction parts 1521 are respectively embedded with magnetic blocks; the flip frame 152 rises and connects to the weighing plate 151 through the magnetic attraction of the first magnetic attraction parts 1511 and the second magnetic attraction parts 1521. Thus, the convenience of detachable connection between the weighing plate 151 and the flip frame 152 is improved through the magnetic connection, and the quick connection and separation between the two are realized, thereby realizing the quick switching between the weighing function and the pouring function of the pouring piece 15.

[0044] To improve the stability of the emptying device 1, the transverse moving member 14 is horizontally slidably connected to the guiding plate 12 through a transverse sliding rail 124 and a transverse sliding block 142. The limiting long hole 123, the transverse sliding rail 124, and the guiding long hole 122 are distributed from top to bottom in sequence. The transverse sliding block 142 is disposed in the middle of the transverse moving member 14. The turning member 13 is located between the transverse moving member 14 and the guiding plate 12. The upper end of the transverse moving member 14 extends obliquely upward away from the emptying side 121 and is provided with the driving groove 141. The lower end extends vertically downward and is penetrated by the rotation of the turning member 13. The lifting area 1231 is located on the side of the guiding long hole 122 away from the emptying side 121. One side of the limiting long hole 123 close to the fixed seat 11 is recessed to form a limiting sliding groove 1232. One side of the guiding long hole 122 away from the fixed seat 11 is recessed to form a guiding sliding groove 1223. The driving end 161 and one end of the turning member 13 are respectively slidably disposed in the limiting sliding groove 1232 and the guiding sliding groove 1223 through bearings. Specifically, the bearings are deep groove ball bearings. Thus, through the cooperation of the transverse sliding rail 124 and the transverse sliding block 142, the middle part of the transverse moving member 14 is supported for horizontal sliding, and it is not restricted by the driving end 161 and the turning member 13 at the upper and lower ends to deflect. At the same time, through the arrangement of the limiting sliding groove 1232 and the guiding sliding groove 1223 on both sides of the guiding plate 12, the structural stability of the guiding plate 12 is improved, and the stability of the emptying driving device 16 driving the transverse moving member 14 to move horizontally and push the turning member 13 to turn horizontally is improved, thereby improving the overall stability of the emptying device 1.

[0045] To further improve the emptying speed, the number of the emptying devices 1 is set to two and they are symmetrically arranged. The adjacent sides of the guiding plates 12 of the two emptying devices 1 are the emptying sides 121. The discharging device 2 includes a receiving box 21 corresponding to the emptying side 121 and used for receiving materials. A hopper 3 with upper and lower ports respectively corresponding to the emptying side 121 and the receiving box 21 is provided between the emptying device 1 and the discharging device 2. A blowing nozzle 31 corresponding to the emptying members 15 of the two emptying devices 1 is provided in the middle of the hopper 3. The two blowing nozzles 31 are connected to an external blowing device and are used to blow the cut tobacco in the turned emptying member 15 downward into the hopper 3. Thus, the emptying speed is improved through the arrangement of the two emptying devices 1, and the cut tobacco after emptying is guided through the addition of the hopper 3 to ensure that all the cut tobacco falls into the receiving box 21. At the same time, through the arrangement of the two blowing devices, the cut tobacco can be prevented from remaining in the emptying member 15, ensuring complete emptying after the emptying member 15 is turned, and improving the emptying speed and the emptying integrity.

[0046] To achieve the full-automatic discharging of the discharging device 2, the discharging device 2 further includes a support frame 22, a turntable 24 rotatably arranged on the support frame 22 and driven by a rotary driving device 23, a cartridge conveyor belt 25 arranged on one side of the turntable 24, and a cartridge discharging driving device 26. Specifically, the rotary driving device 23 is a rotary motor. A plurality of pairs of guiding rib groups 242 extending radially and forming a guiding area 241 therebetween are arranged on the turntable 24 at circumferential intervals. The receiving cartridges 21 are arranged in a plurality of the guiding areas 241, and one receiving cartridge 21 corresponds to the lower end of the hopper 3. The cartridge discharging driving device 26 includes a cartridge discharging support seat 261 arranged on the support frame 22 and a cartridge discharging cylinder 262 arranged on the cartridge discharging support seat 261. The telescopic end of the cartridge discharging cylinder 262 extends transversely along the cartridge conveyor belt 25 and is connected with a cartridge discharging push plate 263 located between a plurality of the receiving cartridges 21. After a receiving cartridge 21 has received the cut tobacco output from the hopper 3, the turntable 24 rotates until the guiding area 241 where a receiving cartridge 21 is located is coaxial with the cartridge conveyor belt 25, and the next receiving cartridge 21 is aligned with the lower end of the hopper 3 to continue receiving the material. Subsequently, the telescopic end of the cartridge discharging cylinder 262 retracts to drive the cartridge discharging push plate 263 to push a receiving cartridge 21 to move horizontally onto the cartridge conveyor belt 25 for forward conveying and discharging. Thus, on the premise of realizing the full-automatic discharging of the receiving cartridge 21, the rapid replacement and positioning of the next-level receiving cartridge 21 are realized through the arrangement of a plurality of receiving cartridges 21, greatly saving the replacement interval of the receiving cartridges 21, enabling the pouring device 1 to continuously pour without stopping work, improving the smoothness and continuity between the pouring step and the receiving step of the discharging mechanism, and further improving the discharging efficiency of the discharging mechanism.

[0047] In order to improve the efficiency of assembling several of the receiving boxes 21 onto the turntable 24, the discharging device 2 further includes a box feeding driving device 27. The box feeding driving device 27 includes a box feeding support base 271 provided on the support frame 22, a swing rod 272 rotatably connected to the box feeding support base 271 to form a rotation point 273, a box feeding air cylinder 274 provided at one end of the swing rod 272, and a swing air cylinder 275 with one end rotatably connected to the support frame 22. The telescopic end of the box feeding air cylinder 274 extends along the material box conveyor belt 25 and is connected to a box feeding push plate 276. The telescopic end of the swing air cylinder 275 is obliquely upward and rotatably connected to the other end of the swing rod 272. The swing air cylinder 275 is used to drive one end of the swing rod 272 to swing around the rotation point 273, so as to drive the box feeding air cylinder 274 to swing above the material box conveyor belt 25 or away from the material box conveyor belt 25. Thus, after one receiving box 21 is laterally moved to the discharge position of the material box conveyor belt 25 and the next receiving box 21 is aligned with the lower end of the hopper 3 to continue receiving materials, first, the material box conveyor belt 25 is reversely rotated to input a new receiving box 21 to the end close to the turntable 24, and then the swing air cylinder 275 is used to push one end of the swing rod 272 to swing around the rotation point 273, driving the box feeding air cylinder 274 to swing above the material box conveyor belt 25 and the box feeding push plate 276 to be located on the side of the new receiving box 21 away from the turntable 24. Thus, the telescopic end of the box feeding air cylinder 274 extends to push the new receiving box 21 to make up the position and enter the vacant guiding area 241. On the premise that the above structure realizes the full-automatic assembly of several receiving boxes 21 into the corresponding guiding areas 241 through the cooperation between the material box conveyor belt 25 and the box feeding driving device 27, after one receiving box 21 is discharged, during the time when the next receiving box 21 is receiving materials, a new receiving box 21 can be made up the position and enter the vacant guiding area 241 through the cooperation between the material box conveyor belt 25 and the box feeding driving device 27, improving the assembly efficiency of the receiving boxes 21 and avoiding the interruption of the receiving of the receiving boxes 21 from affecting the discharging efficiency.

[0050] In order to improve the versatility of the feeding mechanism so that it has the functions of conveying the feeding and discharging of the storage box, the feeding mechanism is arranged on one side of the corresponding rack 8 and includes a plurality of feeding conveyor belts 4 and a plurality of return conveyor belts 5 which are arranged in upper and lower layers. One of the feeding conveyor belts 4 is driven by a lifting drive device 41 to move up and down. The lifting drive device 41 can be set as a lead screw drive assembly arranged vertically. The rack 8 includes a workbench 81 and a discharging area 82 which are distributed up and down. The sampling and weighing mechanism and the pouring device 1 are arranged on the workbench 81, and the discharging device 2 is arranged in the discharging area 82. The hopper 3 penetrates through the workbench 81. When it is necessary to weigh the cut tobacco, the storage box is conveyed to the side of the rack 8 by a plurality of feeding conveyor belts 4 for sampling and weighing by the sampling and weighing mechanism. When it is not necessary to weigh the cut tobacco, the storage box can be conveyed onto one of the conveyor belts 4, and then one of the feeding conveyor belts 4 is driven by the lifting drive device 41 to descend to dock with the return conveyor belt 5, so as to send the storage box back through the return conveyor belt 5. Thus, the feeding mechanism has the functions of conveying the feeding and discharging of the storage box, improving the versatility of the feeding mechanism, and increasing the feeding and return speeds of the storage box.

[0051] Specifically, the number of the sampling and weighing mechanisms is set to two and respectively corresponds to the two discharging devices 1. The sampling and weighing mechanism includes a sampling device 6 and a weighing device 7. The sampling device 6 includes a negative pressure suction cup 62 driven by a cover removal driving device 61 to lift and lower on the feeding conveyor belt 4, a box moving member 64 driven by a box moving driving device 63 to horizontally move between the gaps of the adjacent feeding conveyor belts 4 and the workbench 81, a suction member 66 driven by a sampling driving device 65 to lift and lower corresponding to the box moving member 64, and a horizontal moving driving device 67 for driving the sampling driving device 65 to horizontally move. The weighing device 7 includes a rotating seat 72 located on one side of the box moving member 64 and driven by a wire feeding driving device 71 to rotate, and a weighing scale 73 located on the side of the rotating seat 72 away from the box moving member 64. A flexible vibrating disk 721 for vibrating and discharging materials is provided at the top of the rotating seat 72 and respectively rotates corresponding to the suction member 66 and the weighing scale 73. The discharging device 1 is located on the side of the weighing scale 73 away from the rotating seat 72. The box moving member 64 is located between the adjacent feeding conveyor belts. After the feeding conveyor belt 4 conveys the storage box into the box moving member 64, the negative pressure suction cup 62 descends to adsorb the lid of the storage box and then ascends. The box moving member 64 horizontally moves to below the suction member 66. After the suction member 66 descends into the storage box to suck the cut tobacco, it horizontally moves to the flexible vibrating disk 721 and then deflates to discharge the materials. The rotating seat 72 rotates until the flexible vibrating disk 721 corresponds to the weighing scale 73 and then vibrates and discharges the materials into the weighing pan 151 on the weighing scale 73. Until the preset weight is reached, the rotating seat 72 rotates and resets until the flexible vibrating disk 721 corresponds to the storage box in the box moving member 64, and then vibrates and discharges the remaining cut tobacco back into the storage box. And the flipping frame 152 ascends to connect the weighing pan 151 and then horizontally moves and flips to discharge the materials. Thus, the automatic sampling and weighing operation of automatically taking materials, discharging materials, and weighing the cut tobacco in the storage box by the cut tobacco weighing device is realized. And the whole process is fast and efficient, which can improve the discharging efficiency of the cut tobacco sample, without manual participation, reduce the labor cost and avoid contaminating the cut tobacco at the same time.
