[0035] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0036] refer to Figure 1-10 , a discharging mechanism for a tobacco weighing device, comprising: a discharging device 1 and a discharging device 2 distributed up and down, wherein the discharging device 2 is used for receiving and discharging the material;

[0037] The material pouring device 1 comprises: a fixed seat 11, a guide plate 12 arranged on the fixed seat 11 and having one end as a material pouring side 121, and a flipping member 13, a transverse member 14 and a material pouring member 15 for holding tobacco shreds located on the side of the guide plate 12 away from the fixed seat 11, the guide plate 12 is penetrated by a guide long hole 122 extending laterally toward the material pouring side 121 and then extending obliquely downward to form a flipping area 1211, the transverse member 14 is laterally slidably connected to the guide plate 12, and the fixed seat 11 is provided with a member for driving the transverse member The material dumping drive device 16 of the material dumping device 16 is configured to be horizontally shifted, wherein one end of the flipping member 13 is slidably disposed in the guide slot 122, and the other end rotates through the horizontal shifting member 14 and connects the material dumping member 15; the driving end 161 of the material dumping drive device 16 drives the horizontal shifting member 14 to move horizontally toward the material dumping side 121, and pushes 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 horizontal shifting member 14 to flip toward the material dumping side 121, so as to drive the material dumping member 15 to flip and dump the material into the discharging device 2 after horizontal shifting. Specifically, the material dumping drive device 16 is a screw drive device, and its driving end 161 is disposed at the side and driven to move horizontally left and right. In other embodiments, the material dumping drive device 16 can be configured as other existing horizontal shifting drive devices, such as a cylinder.

[0038] The arrangement of the above structure can realize the fully automatic and rapid pouring and discharging of the tobacco samples taken and weighed by the tobacco weighing equipment, thereby increasing the discharging speed of the tobacco samples and avoiding contamination of the tobacco samples during discharging, thereby improving the production efficiency of cigarette ingredients, ensuring production quality, and accelerating product research and development.

[0039] In order to further increase the flipping angle of the pouring piece 15 and avoid tobacco residue causing incorrect weight of tobacco output by the discharging device 2, the end of the flipping zone 1211 extends obliquely upward toward the pouring side 121 to form an inverting zone 1222; when the transverse moving piece 14 moves laterally toward the pouring side 121 and pushes one end of the flipping piece 13 to slide down along the flipping zone 1211 to between the flipping zone 1211 and the inverting zone 1222, the flipping piece 13 and the pouring piece 15 are flipped to a vertical position toward the pouring side 121, and the pouring piece 15 is flipped 90° at this time, and the transverse moving piece 14 continues to move laterally toward the pouring side 121 to pull one end of the flipping piece 13 to slide up along the inverting zone 1222 and the other end continues to flip toward the pouring side 121, and the pouring piece 15 continues to flip to the top facing down, and at this time, the pouring piece 15 is flipped more than 90°. Therefore, by adding the inverting area 1222, the pouring piece 15 can be further turned over to an inverting angle greater than 90° with the top facing downward after being turned over to the vertical direction, so that all the tobacco contained in the pouring piece 15 can be downwardly introduced into the discharging device 2, avoiding the presence of tobacco residue in the pouring piece 15 during pouring, which would cause the weight of the tobacco sample output by the discharging device 2 to be incorrect, thereby improving the integrity of the pouring device 1 and the accuracy of the discharging of the discharging device 2, thereby ensuring the stability and accuracy of the discharging of the discharging mechanism.

[0040] The tobacco weighing device includes a weighing device 4. In order to enable the pouring piece 15 to simultaneously combine the weighing function of weighing through the weighing device 4 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 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 4 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 piece 14 to rise, so that the turning frame 152 rises and connects to the weighing plate 151. 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 piece 14 to move laterally while continuing to move laterally, thereby causing the transverse moving piece 14 to push the turning piece 13 to move laterally and then flip, thereby driving the turning frame 152 and the weighing plate 151 to move laterally and then 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 4 to the tipping piece 15, and further improving the speed of tipping after the tobacco sample is weighed.

[0041] 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.

[0042] In order to improve the stability of the unloading device 1, the transverse member 14 is connected to the guide plate 12 by transverse sliding rails 124 and transverse sliding blocks 142, the limiting long holes 123, the transverse sliding rails 124, and the guide long holes 122 are arranged from top to bottom in sequence, the transverse sliding blocks 142 are arranged in the middle of the transverse member 14, the flip member 13 is located between the transverse member 14 and the guide plate 12, the upper end of the transverse member 14 extends upwardly in an inclined direction away from the unloading side 121 and is provided with the driving groove 141, and the lower end extends vertically downward and is provided with a The lifting area 1231 is located on the side of the guide long hole 122 away from the dumping side 121, and the side of the limiting long hole 123 close to the fixed seat 11 is recessed to form a limiting groove 1232, and the side of the guide long hole 122 away from the fixed seat 11 is recessed to form a guide groove 1223, and the driving end 161 and one end of the flipping member 13 are respectively slidably arranged in the limiting groove 1232 and the guide groove 1223 through bearings. Specifically, the bearings are set as deep groove ball bearings. Thus, the middle part of the transverse member 14 is supported to slide transversely through the cooperation of the transverse slide rail 124 and the transverse slider 142, and is not restricted by the driving end 161 and the flipping member 13 at the upper and lower ends. At the same time, the setting of the limiting slide groove 1232 and the guide slide groove 1223 on both sides of the guide plate 12 improves the structural stability of the guide plate 12, and improves the stability of the material unloading drive device 16 driving the transverse member 14 to move transversely and push the flipping member 13 to flip after moving transversely, thereby improving the overall stability of the material unloading device 1.

[0043] In order to further increase the material pouring speed, the number of the material pouring devices 1 is set to two and they are symmetrically arranged. The side close to the guide plate 12 of the two material pouring devices 1 is the material pouring side 121. The discharging device 2 includes a material receiving box 21 corresponding to the material pouring side 121 and used for receiving materials.

The two blowing nozzles 31 are connected to an external blowing device and are used to blow the tobacco in the flipped material pouring part 15 downward into the hopper 3. Thus, the pouring speed is improved by setting up two pouring devices 1, and the tobacco shreds after pouring are guided by adding a hopper 3 to ensure that all the tobacco shreds fall into the receiving box 21. At the same time, the two blowing devices can prevent tobacco shreds from remaining in the pouring piece 15, ensure that the pouring piece 15 is completely poured after being turned over, and improve the pouring speed and pouring integrity.

[0044] In order to realize the fully automatic discharging of the discharging device 2, the discharging device 2 also includes a support frame 22, a turntable 24 driven by a rotary drive device 23 and arranged on the support frame 22, a material box conveyor belt 25 arranged on one side of the turntable 24, and a box discharging drive device 26. Specifically, the rotary drive device 23 is set as a rotary motor, and the turntable 24 is provided with a plurality of pairs of guide rib groups 242 extending radially and forming guide areas 241 therebetween at intervals in the circumferential direction. The plurality of guide areas 241 are each provided with the material receiving box 21 and one of the material receiving boxes 21 corresponds to the lower end of the hopper 3. The box discharging drive device 26 includes a box discharging support seat 261 arranged on the support frame 22. , a box discharging cylinder 262 is arranged on the box discharging support seat 261, and the telescopic end of the box discharging cylinder 262 extends horizontally along the material box conveyor belt 25 and is connected to a box discharging push plate 263 located between several of the material receiving boxes 21; after one of the material receiving boxes 21 has received the tobacco output by the hopper 3, the turntable 24 rotates to the guide area 241 where the material receiving box 21 is located, which is coaxial with the material box conveyor belt 25, and the next material receiving box 21 is aligned with the lower end of the hopper 3 to continue receiving the material, and then the telescopic end of the box discharging cylinder 262 retracts to drive the box discharging push plate 263 to push the material receiving box 21 to move horizontally to the material box conveyor belt 25 to convey and discharge the material in a forward direction. Therefore, under the premise of fully automatic material discharge from the material receiving box 21, the setting of a plurality of material receiving boxes 21 can realize the rapid filling and receiving of the next-level material receiving box 21, which greatly saves the replacement interval of the material receiving box 21, so that the material pouring device 1 can continuously pour materials without stopping, thereby improving the smoothness and continuity between the material pouring step and the material receiving step of the material discharging mechanism, thereby improving the material discharging efficiency of the material discharging mechanism.

[0045] 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 drive device 27, which includes a box feeding support seat 271 arranged on the support frame 22, a rocker arm 272 rotatably connected to the box feeding support seat 271 to form a rotation point 273, a box feeding cylinder 274 arranged at one end of the rocker arm 272, and a swing cylinder 275 rotatably connected to the support frame 22 at one end, the telescopic end of the box feeding 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 cylinder 275 is tilted and rotated upward to be connected to the other end of the rocker arm 272, and the swing cylinder 275 is used to drive one end of the rocker arm 272 to swing around the rotation point 273, so as to drive the box feeding cylinder 274 to swing to just above the material box conveyor belt 25 or away from the material box conveyor belt 25. Therefore, after one of the receiving boxes 21 moves horizontally to the box conveyor belt 25 to discharge the material, and when the next receiving box 21 is aligned with the lower end of the hopper 3 to continue receiving the material, the new receiving box 21 is first reversed and input to the end close to the turntable 24 through the box conveyor belt 25, and then the swing cylinder 275 pushes one end of the swing rod 272 to swing around the rotation point 273, driving the box feeding cylinder 274 to swing to the top of the box conveyor belt 25 and the box feeding push plate 276 is located on the side of the new receiving box 21 away from the turntable 24, so that the telescopic end of the box feeding cylinder 274 extends out to push the new receiving box 21 to fill the position and enter the vacant guide area 241. The above structure, under the premise of realizing the fully automatic assembly of several receiving boxes 21 into the corresponding guide areas 241 through the cooperation between the material box conveyor belt 25 and the box feeding drive device 27, can also, after one receiving box 21 discharges the material, fill in the new receiving box 21 into the vacant guide area 241 during the time when the next receiving box 21 receives the material through the cooperation between the material box conveyor belt 25 and the box feeding drive device 27, thereby improving the assembly efficiency of the receiving box 21 and avoiding the interruption of the receiving box 21 in receiving the material and affecting the discharge efficiency.

[0046] In order to improve the stability of the discharging device 2, the angle between one end and the other end of the swing rod 272 is an obtuse angle with the opening facing upward, thereby increasing the swing angle of the swing rod 272 after being driven by the swing cylinder, and increasing the swing stroke of the box feeding cylinder to avoid interference with the work of other devices and improve the adaptability of the box feeding drive device 27. The box feeding support seat 271 is respectively provided with an upper limit column 2711 and a lower limit column 2712 located on the upper and lower sides of the swing rod 272, so that the swing direction of the swing rod 272 is limited by the upper limit column 2711 and the lower limit column 2712 to avoid the swing rod 272 from being too The excessive swing may cause the driving failure of the swing cylinder 275 or the collision between the box feeding cylinder and the box conveyor belt 25. The box outlet support seat 261 is provided with a limit plate 2611 which is parallel to the telescopic end of the box outlet cylinder 262.
