The present embodiment is written in a progressive manner.

[0019] As shown in Figures 1 to 8 A sampling container cleaning mechanism for tobacco moisture content sampling, comprising a cleaning unit 2 composed of a clamping part 3 and a cleaning part 4, the clamping part 3 is used for fixing the sampling container 1, and the cleaning part 4 is used for cleaning the inside of the sampling container 1; The cleaning part 4 comprises a vertical pipe 5, a side brush 7 and a flat brush 8, a plurality of side openings 6 are formed on the outer wall of the vertical pipe 5, and the water or air conveyed in the vertical pipe 5 is sprayed out through the plurality of side openings 6, the side brush 7 is in contact with the inner side wall of the sampling container 1 and is used for cleaning it, and the flat brush 8 is in contact with the bottom of the sampling container 1 and is used for cleaning it; Wherein, the sampling container 1 is invertedly buckled on the cleaning part 4, the side brush 7 and the side opening 6 are located on both sides of the vertical pipe 5 respectively, and the cleaning part 4 rotates in the sampling container 1; In the present application, the sampling container 1 can be fixed on the clamping part 3 and cleaned inside by the cleaning part 4. In order to facilitate the timely discharge of impurities inside the sampling container 1, the sampling container 1 is generally inverted and cleaned. In this way, the impurities can be directly discharged from the opening position of the sampling container 1 by gravity and water flow. The vertical pipe 5 is located at the rotation axis position of the cleaning part 4, and the vertical pipe 5 is vertical. When the sampling container 1 is inverted and placed on the cleaning part 4, the sampling container 1 is located outside the vertical pipe 5. The vertical pipe 5 can support the side brush 7 and the flat brush 8. The side brush 7 is parallel to the vertical pipe 5. In this way, when the side brush 7 cleans the inside of the sampling container 1, the side brush 7 can contact the inner wall of the sampling container 1 along the axis direction of the sampling container 1. In this way, when the side brush 7 rotates with the cleaning part 4, it can clean the inner wall of the sampling container 1 comprehensively. The flat brush 8 can contact the bottom of the sampling container 1. When the cleaning part 4 rotates, it can clean the bottom of the sampling container 1. In this way, the side brush 7 and the flat brush 8 realize comprehensive cleaning of the inside of the sampling container 1. The cleaning method is mainly based on the rotation of the side brush 7 and the flat brush 8 around the axis of the sampling container 1. In use, the sampling container 1 is inverted and placed on the outside of the vertical pipe 5, the side brush 7 and the flat brush 8 of the cleaning part 4, and the clamping part 3 fixes the sampling container 1. The vertical pipe 5 supplies water and sprays it into the inner wall and bottom of the sampling container 1 through the side openings 6, thereby realizing the cleaning of the sampling container 1. At the same time, the cleaning part 4 is rotated to make the side brush 7, the flat brush 8 and the side openings 6 rotate synchronously. The side brush 7 and the flat brush 8 clean the inner wall and the bottom of the sampling container 1, and at the same time, the side openings 6 comprehensively flush the inside of the sampling container 1. When the cleaning part 4 rotates for one round, the flushing work is completed. The water sprayed by the side openings 6 flushes out all the impurities in the sampling container 1. Then, the vertical pipe 5 delivers air, and the side openings 6 start to discharge air flow to dry the inside of the sampling container 1. In this way, the comprehensive and automatic cleaning of the inside of the sampling container 1 is completed. It should be noted that in order to improve the cleaning effect or avoid impurities remaining, the cleaning part 4 can be rotated for at least two rounds. In some embodiments, in order to improve the continuity of the cleaning of the sampling container 1, a vertical column 33 can be provided, and a rotating disc 32 is rotatably arranged on the vertical column 33. A plurality of cleaning units 2 are annularly arranged on the rotating disc 32. In this way, the rotation of the rotating disc 32 can drive the circumferential movement of the plurality of cleaning units 2. The cleaning units 2 can cyclically move among the loading station, the cleaning station, the drying station and the unloading station. The sampling containers 1 on the cleaning units 2 can sequentially pass through the above stations and complete the corresponding operations. By using the automatic cleaning method to clean the impurities inside the sampling container 1, the operation method can be effectively simplified, the time for cleaning the sampling container 1 can be shortened, and the work efficiency can be improved. At the same time, since the side brush 7 and the flat brush 8 can clean different positions inside the sampling container 1, the cleaning effect can be improved, and impurities can be avoided.

[0020] Further, the side brush 7 is rotationally connected with the vertical pipe 5 through a plurality of mutually parallel supporting arms 9, and the bottom of the flat brush 8 is slidingly provided with a supporting seat 10, which is rotationally connected with the top of the vertical pipe 5; Wherein, the top of the side brush 7 is provided with a horizontal transition part 11, which is used for cleaning the connecting area between the inner side wall and the bottom of the sampling container 1, and the end of the transition part 11 is rotationally connected with the flat brush 8; Since the side brush 7 and the flat brush 8 are in contact with the inner side wall and the bottom of the sampling container 1 respectively, the distance between the side brush 7 and the vertical pipe 5 is large, the horizontal length of the flat brush 8 is large, and the caliber of the opening position of the sampling container 1 is small compared with the internal diameter of the sampling container 1, so the flat brush 8 and the side brush 7 will block the opening position of the sampling container 1, which causes the sampling container 1 to be unable to be smoothly inverted on the cleaning part 4. In order to reduce the overall volume of the cleaning part 4, the above structure can be used. When it is needed to invert the sampling container 1 on the cleaning part 4, the side brush 7 is pushed to move upward. Since the plurality of supporting arms 9 connect and guide the side brush 7, the side brush 7 remains in a vertical state and is close to the vertical pipe 5, thereby reducing the distance between the side brush 7 and the vertical pipe 5. The movement of the side brush 7 drives the flat brush 8 to move synchronously through the transition part 11. Due to the limitation of the supporting seat 10, the flat brush 8 will slide on the supporting seat 10, and the flat brush 8 will gradually change from a horizontal state to an inclined state. The flat brush 8 drives the supporting seat 10 to rotate on the vertical pipe 5, thereby reducing the length of the horizontal projection of the flat brush 8. In this way, the projection area of the cleaning part 4 on the horizontal plane is reduced, so that the sampling container 1 is smoothly inverted on the cleaning part 4. By setting the transition part 11, the smooth transition connection between the side brush 7 and the flat brush 8 can be realized, and the area between the inner side wall and the bottom of the sampling container 1 can be conveniently cleaned, avoiding the generation of cleaning dead angles.

[0021] Further, the connecting position of the transition part 11 and the flat brush 8 deviates from the axis of the vertical pipe 5. Since the gap position between the transition part 11 and the flat brush 8 cannot effectively clean the bottom of the sampling container 1 when they are connected, if the gap position is located on the axis of the vertical pipe 5, a cleaning blind area will appear. If the gap position deviates from the axis of the vertical pipe 5, i.e. the gap position is located on one side of the vertical pipe 5, the part of the flat brush 8 located on the other side of the vertical pipe 5 will clean the part missed by the gap position when the cleaning part 4 rotates, thereby improving the comprehensiveness of cleaning.

[0022] Further, the cleaning part 4 further comprises a sub-brush 12, a sub-brush 13 and a shoulder brush 17, the shoulder brush 17 is arranged at the bottom of the side brush 7, and the shoulder brush 17 is used for cleaning the shoulder of the inner wall of the sampling container 1 near the opening position, the sub-brush 12 is arranged at the bottom of the shoulder brush 17 and is used for cleaning the inner wall of the opening position of the sampling container 1, and the sub-brush 13 is arranged at the bottom of the sub-brush 12 and is used for cleaning the outer edge of the opening position of the sampling container 1; As shown in Figure 5 The shoulder brush 17, the sub-brush 12 and the sub-brush 13 are arranged in sequence at the lower side of the side brush 7, and the shapes thereof are consistent with the shape of the opening position of the sampling container 1, so that when the cleaning part 4 rotates, the inner wall, the shoulder and the outer edge of the opening position of the sampling container 1 can be cleaned by the sub-brush 12, the sub-brush 13 and the shoulder brush 17, so as to avoid the same impurities remaining at the opening position of the sampling container 1 and affecting the detection work.

[0023] Further, a moving sleeve 14 is slidably arranged on the outer wall of the vertical pipe 5, the moving sleeve 14 is rotationally connected with a supporting arm 9 through an inclined push-pull rod 15, and the moving sleeve 14 is connected with the sub-brush 12 through an inclined slope plate 16; The sub-brush 12 is fixedly connected with the sub-brush 13, and the sub-brush 12 is detachably arranged with the shoulder brush 17; Since the sub-brush 12, the sub-brush 13 and the shoulder brush 17 are used for cleaning different regions of the opening position of the sampling container 1, the sub-brush 12, the sub-brush 13 and the shoulder brush 17 can form an arc shape, which cannot directly match the opening position of the sampling container 1 when the sampling container 1 is inverted and placed on the cleaning part 4, so that the shoulder brush 17 and the sub-brush 12 are detachable, that is, the arc shape is detachable, so as to facilitate combination and cleaning of the opening position of the sampling container 1; The moving sleeve 14 can provide support for the sub-brush 12 and the sub-brush 13, and when the moving sleeve 14 moves, it will push the corresponding supporting arm 9 to rotate through the push-pull rod 15, so as to move the side brush 7 and push the flat brush 8 to incline, at this time, the cleaning part 4 is deformed and folded, the side brush 7 drives the shoulder brush 17 to move synchronously and separate from the sub-brush 12; the inclined arrangement of the slope plate 16 can be used for guiding the sampling container 1 when the bottle opening position of the sampling container 1 contacts the slope plate 16, so that the sub-brush 12 and the sub-brush 13 can smoothly contact the corresponding positions on the sampling container 1.

[0024] Further, a plurality of openings 18 are formed in the outer wall of the moving sleeve 14, a roller 19 is rotationally arranged in each opening 18, the roller 19 is in transmission contact with the outer wall of the vertical pipe 5, a connecting rod 20 is arranged on each roller 19, an end of the connecting rod 20 is rotationally arranged with a rolling body 21, and the rolling body 21 is used for pressing the shoulder of the inner wall of the sampling container 1 near the opening position and fixing the sampling container 1 on the clamping part 3; When the movable sleeve 14 moves relative to the vertical tube 5, the movable sleeve 14 drives the roller 19, the connecting rod 20 and the rolling body 21 thereon to move synchronously. Since the roller 19 is in driving contact with the outer wall of the vertical tube 5, the roller 19 rotates in the notch 18, and the roller 19 drives the connecting rod 20 and the rolling body 21 to rotate upward or tilt downward. like Figure 5 As shown, when the movable sleeve 14 moves upward and pushes the side brush 7 and the flat brush 8 to retract, the roller 19 rotates synchronously and drives the connecting rod 20 and the rolling body 21 to move upward. At this time, the connecting rods 20 and the rolling bodies 21 are all close to the vertical tube 5, thereby facilitating the smooth inversion of the sampling container 1 on the cleaning portion 4. When the movable sleeve 14 moves downward, the side brush 7 and the flat brush 8 return to the working position. At this time, the connecting rod 20 and the rolling body 21 tilt downward, and the rolling body 21 contacts the shoulder position of the inner wall of the sampling container 1, thereby utilizing the rolling bodies 21 to generate downward pressure on the sampling container 1. The sampling container 1 is pressed onto the clamping portion 3. At the same time, since the plurality of rolling bodies 21 synchronously provide a force to the shoulder position inside the sampling container 1, the plurality of rolling bodies 21 can realize the fixed-axis positioning of the sampling container 1, so that the sampling container 1 and the vertical tube 5 are coaxial. In this way, when the cleaning portion 4 rotates, the side brush 7 can contact all positions of the inner wall of the sampling container 1, and the force between the side brush 7 and the sampling container 1 is uniform; since the cleaning portion 4 can rotate relative to the sampling container 1, the rolling body 21 can roll on the shoulder position of the inner wall of the sampling container 1, thereby avoiding friction.

[0025] Furthermore, the clamping portion 3 includes a cone 22, a plurality of sliders 23 that slide obliquely and slideably on the inner side of the cone 22, and a rubber sleeve 24 located between the sliders 23. The rubber sleeve 24 is provided with two stop edges, and the slider 23 is located between the two stop edges. A shoulder support 25 is provided on the top of the rubber sleeve 24 for supporting the shoulder of the outer wall of the sampling container 1. The rubber sleeve 24 is connected to the cone 22 by a plurality of springs 26. A discharge pipe 28 is provided at the bottom of the cone 22. The bottom of the vertical pipe 5 and the bottom of the movable sleeve 14 slide through the discharge pipe 28. The conical cylinder 22 can be fixed on the rotating disc 32 by bolts, the inner shape of the conical cylinder 22 is conical, by using the shape characteristics, when the plurality of sliding blocks 23 move synchronously up and down, the distance between them synchronously approaches or moves away, thereby the plurality of sliding blocks 23 can squeeze or loosen the rubber sleeve 24, the two stoppers on the rubber sleeve 24 can be used to limit the sliding blocks 23, thereby the rubber sleeve 24 is clamped on the plurality of sliding blocks 23; the bottle opening position of the sampling container 1 can be inserted into the rubber sleeve 24, and the shoulder position of the sampling container 1 can be overlapped on the shoulder support 25, when the plurality of rolling bodies 21 in the cleaning part 4 press the sampling container 1 downward, the sampling container 1 can push the plurality of sliding blocks 23 and the rubber sleeve 24 to move downward, the plurality of sliding blocks 23 approach each other and squeeze and fix the bottle opening position of the sampling container 1 by using the rubber sleeve 24, at this time the spring 26 is elastically deformed; when the sampling container 1 is cleaned, the impurities in it can be discharged through the conical cylinder 22 and the discharge pipe 28; Since the cleaning part 4 needs to rotate, the cleaning part 4 further comprises a rotating wheel 29 and a support plate 31 located below the discharge pipe 28, the vertical pipe 5 is installed on the rotating wheel 29, the rotating wheel 29 is eccentrically provided with a pneumatic cylinder 30, the movable end of the pneumatic cylinder 30 is connected with the moving sleeve 14, thereby the pneumatic cylinder 30 can drive the moving sleeve 14 to move on the vertical pipe 5, the rotating wheel 29 can be rotatably installed on the support plate 31, the support plate 31 is fixed on the bottom of the rotating disc 32, when the rotating wheel 29 rotates, it can drive the cleaning part 4 to rotate; in order to realize the rotation of the rotating wheel 29, a transmission ring 34 can be arranged on the stand column 33, the plurality of rotating wheels 29 are connected with the transmission ring 34 through transmission belts 35, thereby when the rotating disc 32 rotates, the transmission ring 34 and the transmission belts 35 can make each rotating wheel 29 in a state of rotation, of course, an independent motor structure can also be arranged for each rotating wheel 29.

[0026] Further, the adjacent two sliding blocks 23 are slidably connected through the plurality of sliding rods 27; When the plurality of sliding blocks 23 squeeze the rubber sleeve 24, the gap between the adjacent two sliding blocks 23 cannot provide effective squeezing to the rubber sleeve 24, by using the plurality of sliding rods 27 arranged between the adjacent two sliding blocks 23, the overall squeezing effect in the circumferential direction of the rubber sleeve 24 can be realized, when the adjacent two sliding blocks 23 relatively move, the sliding rod 27 can slide relative to the sliding block 23; in some embodiments, in order to avoid the separation of the sliding rod 27 and the sliding block 23, a protrusion or the like structure for limiting the movement space of the sliding rod 27 can be arranged on the sliding block 23.

[0027] The above is only the preferred embodiment of the present application, it should be pointed out that, for ordinary skilled in the art, without departing from the technical principles of the present application, a plurality of improvements and modifications can also be made, these improvements and modifications should also be regarded as the protection scope of the present application.
