Description

Technical Field

[0001] This invention relates to the technical field of cleaning structures, and in particular to a cleaning mechanism for a sampling container used for tobacco moisture content testing. Background Technology

[0002] To test the quality of tobacco, especially its moisture content, it is usually necessary to extract representative samples from a large batch of tobacco. These samples need to be placed in a dedicated sampling container for transport to a laboratory or on-site testing point for moisture determination. As the carrier of the sample, the cleanliness of the sampling container itself has a decisive impact on the accuracy and reliability of the test results. Any foreign matter remaining on the inner wall of the container, such as tobacco dust, grease, moisture, or other contaminants left over from previous samples, may contaminate the newly loaded sample to be tested, leading to significant deviations in the test results. Therefore, cleaning the sampling container is an important measure to improve the accuracy of the test.

[0003] Traditional cleaning methods are mainly done by workers who use brushes or spray nozzles to scrub and rinse the containers to remove impurities. After that, the containers are dried. However, since tobacco moisture content testing covers the entire tobacco production process, the testing volume is large and the testing frequency is high. Manual cleaning of sampling containers would result in a slow supply of containers, which would not be able to meet the testing needs. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a cleaning mechanism for a sampling container used for tobacco moisture content testing, the specific technical solution of which is as follows: The present invention provides a cleaning mechanism for a sampling container for testing the moisture content of tobacco, comprising a cleaning unit consisting of a clamping part and a cleaning part, wherein the clamping part is used to fix the sampling container and the cleaning part is used to clean the inside of the sampling container; The cleaning unit includes a vertical tube, a side brush, and a flat brush. The outer wall of the vertical tube has several side openings. Water or air transported inside the vertical tube is sprayed out through the side openings. The side brush contacts the inner side wall of the sampling container and is used to clean it. The flat brush contacts the bottom of the sampling container and is used to clean it. The sampling container is inverted on the cleaning section, the side brush and the side opening are located on both sides of the vertical tube, and the cleaning section rotates inside the sampling container.

[0005] Furthermore, the side brush is rotatably connected to the vertical tube via several parallel support arms, and a support seat is slidably provided at the bottom of the flat brush, the support seat being rotatably connected to the top of the vertical tube. The side brush has a horizontal transition section at its top, which is used to clean the connection area between the inner wall and the bottom of the sampling container. The end of the transition section is rotatably connected to the flat brush.

[0006] Furthermore, the connection position between the transition section and the flat brush is offset from the axis of the vertical tube.

[0007] Furthermore, the cleaning unit also includes a secondary brush one, a secondary brush two, and a shoulder brush. The shoulder brush is located at the bottom of the side brush and is used to clean the shoulder part of the inner wall of the sampling container near its opening. The secondary brush one is located at the bottom of the shoulder brush and is used to clean the inner wall of the sampling container at the opening. The secondary brush two is located at the bottom of the secondary brush one and is used to clean the outer edge of the sampling container at the opening.

[0008] Furthermore, a movable sleeve is slidably fitted on the outer wall of the vertical tube, and the movable sleeve is rotatably connected to one of the support arms through an inclined push-pull rod. The movable sleeve is connected to the auxiliary brush one through an inclined slope plate. The auxiliary brush one and the auxiliary brush two are fixedly connected, while the auxiliary brush one and the shoulder brush can be detached.

[0009] Furthermore, the outer wall of the movable sleeve is provided with several notches, and a roller is rotatably arranged in each notch. The roller is in driving contact with the outer wall of the vertical tube. Each roller is provided with a connecting rod, and a rolling element is rotatably arranged at the end of the connecting rod. The rolling element is used to squeeze the shoulder of the inner side wall of the sampling container near its opening and fix the sampling container on the clamping part.

[0010] Furthermore, the clamping part includes a cone, a plurality of sliders that are inclined and slidably located inside the cone, and a rubber sleeve located between the plurality of sliders. The rubber sleeve is provided with two baffles, and the sliders are located between the two baffles. The top of the rubber sleeve is provided with a shoulder support for supporting the shoulder of the outer wall of the sampling container. The rubber sleeve and the cone are connected by several springs. The bottom of the cone is connected to a discharge pipe, and the bottom of the vertical pipe and the bottom of the movable sleeve slide through the discharge pipe.

[0011] Furthermore, adjacent sliders are slidably connected by several sliding rods.

[0012] The beneficial effects of this invention are as follows: By using an automatic cleaning method to remove impurities from the inside of the sampling container, the operation can be effectively simplified, the cleaning time of the sampling container can be shortened, and the work efficiency can be improved.

[0019] like Figures 1 to 8 As shown, a cleaning mechanism for a sampling container for tobacco moisture content testing according to the present invention includes a cleaning unit 2 consisting of a clamping part 3 and a cleaning part 4. The clamping part 3 is used to fix the sampling container 1, and the cleaning part 4 is used to clean the inside of the sampling container 1. The cleaning unit 4 includes a vertical pipe 5, a side brush 7, and a flat brush 8. Several side openings 6 are provided on the outer wall of the vertical pipe 5. Water or air transported in the vertical pipe 5 is sprayed out through the side openings 6. The side brush 7 contacts the inner side wall of the sampling container 1 and is used to clean it. The flat brush 8 contacts the bottom of the sampling container 1 and is used to clean it. The sampling container 1 is inverted on the cleaning section 4, the side brush 7 and the side opening 6 are located on both sides of the vertical tube 5, and the cleaning section 4 rotates inside the sampling container 1. In this invention, the sampling container 1 can be fixed on the clamping part 3, and the cleaning part 4 is used to clean the inside of the sampling container 1. To facilitate the timely discharge of impurities inside the sampling container 1, the sampling container 1 is generally cleaned upside down, so that impurities can be discharged directly from the opening of the sampling container 1 by gravity and water flow. The vertical tube 5 is located at the rotation axis of the cleaning part 4, and the vertical tube 5 is vertical. When the sampling container 1 is upside down on the cleaning part 4, the sampling container 1 is located outside the vertical tube 5, and the vertical tube 5 can support the side brush 7 and the horizontal brush 8. The side brush 7 and the vertical tube The side brush 7 is parallel to the sampling container 1, so that when cleaning the inside of the sampling container 1, the side brush 7 can contact the inner wall of the sampling container 1 along the axis of the sampling container 1. Thus, when the side brush 7 rotates with the cleaning part 4, it can thoroughly clean the inner wall of the sampling container 1. The flat brush 8 can contact the bottom of the sampling container 1. When the cleaning part 4 rotates, it will clean the bottom of the sampling container 1. Thus, the side brush 7 and the flat brush 8 are used to achieve a thorough cleaning of the inside of the sampling container 1. This 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 placed upside down on the outside of the vertical tube 5, side brush 7, and flat brush 8 on the cleaning unit 4, and the clamping part 3 fixes the sampling container 1. The vertical tube 5 supplies water and sprays it onto the inner wall and bottom of the sampling container 1 through several side ports 6, thereby cleaning the sampling container 1. At the same time, the cleaning unit 4 is rotated, so that the side brush 7, flat brush 8 and side ports 6 rotate synchronously. The side brush 7 and flat brush 8 clean the inner wall and bottom of the sampling container 1, while the side ports 6 thoroughly rinse the inside of the sampling container 1. When the cleaning unit 4 rotates one revolution, the rinsing work is completed. The water sprayed from the side ports 6 flushes out all the impurities in the sampling container 1. Then, the vertical tube 5 supplies air, and the side ports 6 start to discharge airflow. The airflow dries 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 the residue of impurities, the cleaning part 4 can be rotated at least twice. In some embodiments, to improve the continuity of cleaning of the sampling container 1, a column 33 can be set, and a turntable 32 is rotatably set on the column 33. Several cleaning units 2 are arranged in a ring on the turntable 32. The rotation of the turntable 32 can drive the several cleaning units 2 to move in a circular motion. The cleaning units 2 can circulate in positions such as loading station, cleaning station, drying station, and unloading station. The sampling container 1 on the cleaning unit 2 can pass through the above stations in sequence and complete the corresponding operation. By using an automatic cleaning method to remove impurities from the inside of the sampling container 1, the operation can be effectively simplified, the cleaning time of 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] Furthermore, the side brush 7 is rotatably connected to the vertical tube 5 via several parallel support arms 9, and the bottom of the flat brush 8 is slidably provided with a support seat 10, which is rotatably connected to the top of the vertical tube 5. The side brush 7 has a horizontal transition section 11 at its top. The transition section 11 is used to clean the connection area between the inner wall and the bottom of the sampling container 1. The end of the transition section 11 is rotatably connected to the flat brush 8. Since the side brush 7 and the flat brush 8 contact the inner wall and bottom of the sampling container 1 respectively, the distance between the side brush 7 and the vertical tube 5 is relatively large, and the horizontal length of the flat brush 8 is relatively large. However, the diameter of the opening of the sampling container 1 is smaller than the internal diameter of the sampling container 1. Therefore, the flat brush 8 and the side brush 7 will block the opening of the sampling container 1, preventing the sampling container 1 from being smoothly inverted onto the cleaning section 4. To reduce the overall volume of the cleaning section 4, the above-mentioned structure can be adopted. When it is necessary to invert the sampling container 1 onto the cleaning section 4, the side brush 7 is pushed upward. Due to the support arms 9 supporting the side brush... 7 is connected and guided, so the side brush 7 remains vertical and close to the vertical tube 5, thereby reducing the distance between the side brush 7 and the vertical tube 5. The movement of the side brush 7 will drive the flat brush 8 to move synchronously through the transition part 11. Due to the limitation of the support base 10, the flat brush 8 will slide on the support base 10, and the flat brush 8 will gradually change from a horizontal state to an inclined state. The flat brush 8 drives the support base 10 to rotate on the vertical tube 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 can be easily inverted on the cleaning part 4. By setting the transition section 11, a smooth transition connection between the side brush 7 and the flat brush 8 can be achieved, and it is convenient to clean the area between the inner wall and the bottom of the sampling container 1, avoiding the creation of cleaning dead corners.

[0021] Furthermore, the connection position between the transition section 11 and the flat brush 8 is offset from the axis of the vertical tube 5; Since the gap between the transition section 11 and the flat brush 8 cannot effectively clean the bottom of the sampling container 1, if the gap is located on the axis of the vertical tube 5, a cleaning blind spot will appear. However, if the gap is deviated from the axis of the vertical tube 5, that is, if the gap is located on one side of the vertical tube 5, the part of the flat brush 8 on the other side of the vertical tube 5 will clean the part missed by the gap when the cleaning section 4 rotates, thereby improving the comprehensiveness of cleaning.

[0022] Furthermore, the cleaning unit 4 also includes a secondary brush 12, a secondary brush 2 13, and a shoulder brush 17. The shoulder brush 17 is located at the bottom of the side brush 7 and is used to clean the shoulder of the inner wall of the sampling container 1 near its opening. The secondary brush 12 is located at the bottom of the shoulder brush 17 and is used to clean the inner wall of the sampling container 1 at the opening. The secondary brush 2 13 is located at the bottom of the secondary brush 12 and is used to clean the outer edge of the sampling container 1 at the opening. like Figure 5 As shown, the shoulder brush 17, auxiliary brush 12, and auxiliary brush 2 13 are arranged sequentially on the lower side of the side brush 7, and their shapes are consistent with the shape of the opening of the sampling container 1. Thus, when the cleaning part 4 rotates, the auxiliary brush 12, auxiliary brush 2 13, and shoulder brush 17 can be used to clean the inner wall, shoulder, and outer edge of the opening of the sampling container 1, avoiding the presence of impurities at the opening of the sampling container 1 and preventing them from affecting the testing work.

[0023] Furthermore, a movable sleeve 14 is slidably sleeved on the outer wall of the vertical pipe 5. The movable sleeve 14 is rotatably connected to a support arm 9 through an inclined push-pull rod 15. The movable sleeve 14 is connected to the auxiliary brush 12 through an inclined slope plate 16. Among them, secondary brush 12 and secondary brush 2 are fixedly connected, while secondary brush 12 and shoulder brush 17 can be detached; Since the auxiliary brush 12, auxiliary brush 2 13 and shoulder brush 17 clean different areas of the opening of the sampling container 1, they can form an arc shape. When the sampling container 1 is upside down on the cleaning part 4, this shape cannot be directly matched with the opening of the sampling container 1. Therefore, it is necessary to adopt a method in which the shoulder brush 17 and auxiliary brush 12 can be separated, that is, the arc shape can be disassembled, so as to facilitate assembly and cleaning of the opening of the sampling container 1. The movable sleeve 14 provides support for the auxiliary brush 12 and auxiliary brush 2 13. When the movable sleeve 14 moves, it pushes the corresponding support arm 9 to rotate through the push-pull rod 15, thereby moving the side brush 7 and pushing the flat brush 8 to tilt. At this time, the cleaning part 4 deforms and retracts, and the side brush 7 drives the shoulder brush 17 to move synchronously and separate from the auxiliary brush 12. The inclined setting of the slope plate 16 can be used to guide the sampling container 1 when the bottle mouth position of the sampling container 1 contacts the slope plate 16, so that the auxiliary brush 12 and auxiliary brush 2 13 can smoothly contact the corresponding positions on the sampling container 1.

[0024] Furthermore, the outer wall of the movable sleeve 14 is provided with several notches 18, and each notch 18 is rotatably provided with a roller 19, and the roller 19 is in transmission contact with the outer wall of the vertical tube 5. Each roller 19 is provided with a connecting rod 20, and the end of the connecting rod 20 is rotatably provided with a rolling element 21. The rolling element 21 is used to squeeze the shoulder of the inner side wall of the sampling container 1 near its opening and fix 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 will drive the roller 19, connecting rod 20 and rolling body 21 on it to move synchronously. Since the roller 19 is in transmission contact with the outer wall of the vertical tube 5, the roller 19 will rotate in the notch 18. The roller 19 drives the connecting rod 20 and 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 flat brush 8 to retract, the roller 19 rotates synchronously and drives the connecting rod 20 and the rolling element 21 to move upward. At this time, several connecting rods 20 and several rolling elements 21 move towards the vertical tube 5, which facilitates the sampling container 1 to be smoothly inverted on the cleaning part 4. When the movable sleeve 14 moves downward, the side brush 7 and flat brush 8 return to their working positions. At this time, the connecting rod 20 and the rolling element 21 tilt downward, and the rolling element 21 contacts the shoulder of the inner wall of the sampling container 1. Thus, the several rolling elements 21 generate downward pressure on the sampling container 1. The sampling container 1 is pressed onto the clamping part 3. At the same time, since several rolling elements 21 simultaneously provide force to the shoulder position inside the sampling container 1, the rolling elements 21 can achieve the fixed axis positioning of the sampling container 1, making the sampling container 1 coaxial with the vertical tube 5. In this way, when the cleaning part 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 part 4 can rotate relative to the sampling container 1, the rolling elements 21 can roll at the shoulder position of the inner wall of the sampling container 1, thereby avoiding friction.

[0025] Furthermore, the clamping part 3 includes a cone 22, a plurality of sliders 23 that are inclined and slidably located inside the cone 22, and a rubber sleeve 24 located between the plurality of sliders 23. The rubber sleeve 24 is provided with two baffles, and the sliders 23 are located between the two baffles. The top of the rubber sleeve 24 is provided with a shoulder support 25 for supporting the shoulder of the outer wall of the sampling container 1. Among them, the rubber sleeve 24 is connected to the cone 22 by several springs 26, and the bottom of the cone 22 is connected to the discharge pipe 28. The bottom of the vertical pipe 5 and the bottom of the movable sleeve 14 slide through the discharge pipe 28. The cone 22 can be fixed to the turntable 32 by bolts. The internal shape of the cone 22 is conical. Utilizing this shape characteristic, when several sliders 23 move up and down synchronously, the distance between them moves closer or further away synchronously. Thus, the several sliders 23 can squeeze or loosen the rubber sleeve 24. The two retaining edges on the rubber sleeve 24 can be used to restrict the sliders 23, thereby making the rubber sleeve 24 stuck on the several sliders 23. The bottle mouth of the sampling container 1 can be inserted into the rubber sleeve 24, and the shoulder of the sampling container 1 can be attached to the shoulder support 25. When several rolling elements 21 in the cleaning part 4 press down on the sampling container 1, the sampling container 1 can push several sliders 23 and the rubber sleeve 24 to move down. The several sliders 23 move closer to each other and use the rubber sleeve 24 to squeeze and fix the bottle mouth of the sampling container 1. At this time, the spring 26 undergoes elastic deformation. When the sampling container 1 is cleaned, the impurities inside can be discharged through the cone 22 and the discharge pipe 28. Since the cleaning section 4 needs to rotate, it also includes a rotating wheel 29 and a support plate 31 located below the discharge pipe 28. The vertical pipe 5 is mounted on the rotating wheel 29, and a cylinder 30 is eccentrically mounted on the rotating wheel 29. The movable end of the cylinder 30 is connected to the movable sleeve 14, so the cylinder 30 can push the movable sleeve 14 to move on the vertical pipe 5. The rotating wheel 29 is rotatably mounted on the support plate 31, and the support plate 31 is fixed to the bottom of the turntable 32. When the rotating wheel 29 rotates, it can drive the cleaning section 4 to rotate. To realize the rotation of the rotating wheel 29, a transmission ring 34 can be set on the column 33. Several rotating wheels 29 are connected to the transmission ring 34 through a transmission belt 35. So when a single turntable 32 rotates, the transmission ring 34 and the transmission belt 35 can be used to make each rotating wheel 29 rotate. Of course, an independent motor structure can also be set for each rotating wheel 29.

[0026] Furthermore, adjacent sliders 23 are slidably connected by several sliding rods 27; When several sliders 23 compress the rubber sleeve 24, the gap between two adjacent sliders 23 cannot provide effective compression to the rubber sleeve 24. By using several sliding rods 27 arranged between two adjacent sliders 23, a comprehensive compression effect in the circumferential direction of the rubber sleeve 24 can be achieved. When two adjacent sliders 23 move relative to each other, the sliding rods 27 can slide relative to the sliders 23. In some embodiments, in order to prevent the sliding rods 27 from separating from the sliders 23, protrusions or other structures for limiting the movement space of the sliding rods 27 can be provided on the sliders 23.

[0027] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
