Description

Technical Field

[0001] The utility model relates to the technical field of determination of tobacco filling value. Specifically, it relates to a sample recovery and cleaning system for a tobacco filling value measuring bucket. Background Art

[0002] The quality of tobacco shreds has a great influence on the sensory quality of cigarettes and also has a greater impact on the effective operation rate of cigarette making and tipping equipment. The filling ability of tobacco shreds and the loss in the tobacco processing process basically determine the tobacco consumption per case of cigarettes, and even affect the consumption of other materials. As an important index for quality control in the tobacco processing production process of cigarettes, the tobacco filling value has received extensive attention and emphasis in the industry. Therefore, tobacco filling value measuring instruments have been widely used, providing a scientific detection means for quality control in the tobacco processing production of the industry.

[0003] At present, there is only one measuring bucket in the tobacco filling value measuring instruments on the market. When conducting detection, it is necessary to manually feed materials into the measuring bucket, then place the measuring bucket at the measuring position for detection. After the detection is completed, the measuring bucket is manually cleaned. Then, materials are manually fed again to conduct the next filling value detection. Such repeated operations result in high labor intensity, high labor cost, and low detection efficiency.

[0004] Therefore, it is necessary to automate the existing tobacco filling value measuring instruments to improve the detection efficiency, reduce the labor intensity, and lower the labor cost. After the sample test is completed, how to recover the sample and clean the measuring bucket is the key point of the transformation.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

A number of U-shaped clamping plates arranged in a circumferential array are integrally formed on the outer circumference of the rotating drive plate. Each cup body is respectively clamped in the U-shaped groove of each corresponding U-shaped clamping plate. Rotating plungers are installed on both sides of the U-shaped groove on the U-shaped clamping plate. Positioning grooves are opened on the circular ring flange of the corresponding cup body at the positions corresponding to the rotating plungers, and the lower ends of the rotating plungers are correspondingly inserted into the corresponding positioning grooves.

[0014] Based on the above, the cleaning component includes an electric push rod. The electric push rod is vertically arranged directly above the cup body at the cleaning station. The piston rod of the electric push rod extends from the lower end of the cylinder body. A brush head is fixedly installed at the lower end of the piston rod of the electric push rod. The outer diameter of the brush head is the same as the inner diameter of the cup body.

[0015] Based on the above, it further includes a partition plate, which is horizontally arranged above each cup body. The four sides of the partition plate are fixedly supported on the bottom plate through vertical support plates. A first through hole corresponding vertically to the cup body at the material cleaning station is opened on the partition plate.

Specifically, the utility model is provided with at least three cup barrel assemblies, and each cup barrel assembly is circumferentially and arrayed on the reference plate. The rotary assembly drives each cup barrel assembly to intermittently rotate on the reference plate at an angle between adjacent two cup barrel assemblies. When the cup barrel assembly rotates to the feeding station, a quantitative amount of tobacco sample is filled into the cup body. Then, the cup barrel assembly rotates to the measuring station, and the filling value of the tobacco sample in the cup body is measured. After measuring the filling value, the cup barrel assembly rotates to the material cleaning station. The piston rod of the electric push rod extends downward, so that the brush head extends into the lower cup body, and then the tobacco sample in the cup body is pushed out, and the tobacco sample falls into the waste collection barrel through the first and second material dropping holes for recovery. At the same time, the brush head synchronously cleans the inner wall of the cup body to ensure that the tobacco sample in the cup body is cleaned up. The cleaned cup barrel assembly can then rotate back to the feeding station in a cycle, realizing continuous cyclic operation, improving the detection efficiency, reducing the labor intensity, lowering the labor cost, cleaning the cup body while recovering the sample, and being beneficial to the transformation of the automatic test of the tobacco filling value.

[0030] The following is a further detailed description of the technical solution of the present utility model through specific embodiments

[0031] As Figures 1-8 shown, this embodiment provides a sample recovery and cleaning system for a tobacco filling value measuring bucket, including a bottom plate 1, a reference plate 2, at least three cup bucket assemblies with openings at both the top and bottom, a rotary assembly, a material cleaning assembly, and a waste collection bucket 3

[0032] The reference plate 2 is fixed on the upper surface of the bottom plate 1. Each cup and bucket assembly is arranged in a circumferential array on the reference plate 2. The rotating assembly is installed on the bottom plate 1 and fixedly connected to each cup and bucket assembly. The rotating assembly drives each cup and bucket assembly to intermittently rotate on the reference plate 2 at an angle between adjacent two cup and bucket assemblies. The lower end of the cup and bucket assembly is in sealed sliding contact with the upper surface of the reference plate 2;

[0033] There are three working stations on the reference plate 2 along the movement track of the cup and bucket assembly: a feeding station, a measuring station, and a material cleaning station. The feeding station, the measuring station, and the material cleaning station are arranged in sequence according to the rotation direction of the cup and bucket assembly. The reference plate 2 is provided with a first blanking hole 4 at the material cleaning station. The bottom plate 1 is provided with a second blanking hole 5 at the material cleaning station. The inner diameter of the second blanking hole 5 ≥ the inner diameter of the first blanking hole 4 ≥ the inner diameter of the cup and bucket assembly. The outer diameter of the cup and bucket assembly > the inner diameter of the first blanking hole 4;

[0034] The material cleaning assembly is arranged above the material cleaning station and is used to push out the cut tobacco in the cup and bucket assembly located at the material cleaning station and clean the inner wall of the cup and bucket assembly, so that the cut tobacco falls through the first blanking hole 4 and the second blanking hole 5;

[0035] The waste collection bucket 3 is arranged below the bottom plate 1 and directly below the second blanking hole 5, and is used to receive the cut tobacco pushed out from the cup and bucket assembly by the material cleaning assembly.

[0036] The cup and bucket assembly includes a cup body 6. The cup body 6 is open at both the upper and lower ends. A circular ring flange 7 is integrally formed on the outer circumference of the lower end of the cup body 6. The lower end of the circular ring flange 7 is fixedly connected to a bottom support 8 sleeved on the lower end of the cup body 6. A circular ring step in contact with the lower end of the cup body 6 is integrally formed on the inner circle of the lower end of the bottom support 8. The inner diameter of the circular ring step is the same as the inner diameter of the cup body 6. The outer diameter of the bottom support 8 > the inner diameter of the first blanking hole 4 ≥ the inner diameter of the cup body 6. The lower end surface of the bottom support 8 presses on the upper surface of the reference plate 2 and is in sealed sliding contact with the upper surface of the reference plate 2. The contact between the bottom support 8 and the reference plate 2 is smooth. After the quantitative cut tobacco is filled into the cup body 6, it rotates on the reference plate 2 with the cup body 6, and the bottom support 8 ensures that as little cut tobacco as possible leaks out.

[0037] The rotating assembly includes a rotating drive plate 9 and a hollow rotating platform 10. The rotating drive plate 9 is arranged directly above the reference plate 2. The hollow rotating platform 10 is fixedly installed in the middle of the bottom plate 1. A central hole is provided in the middle of the reference plate 2. The hollow rotating platform 10 is located in the central hole of the reference plate 2. The rotating drive plate 9 is fixedly installed at the upper end of the hollow turntable of the hollow rotating platform 10. A number of U-shaped clamping plates 11 arranged in a circumferential array are integrally formed on the outer circumference of the rotating drive plate 9. Each cup body 6 is respectively clamped in the U-shaped grooves of the corresponding U-shaped clamping plates 11. Rotary plungers 12 are installed on both sides of the U-shaped groove on the U-shaped clamping plate 11. Positioning grooves are provided on the circular flange 7 of the corresponding cup body 6 at the positions corresponding to the rotary plungers 12. The lower ends of the rotary plungers 12 are correspondingly inserted into the corresponding positioning grooves. During operation, the hollow turntable of the hollow rotating platform 10 drives the rotating support plate to rotate intermittently. The angle of each rotation is the angle between adjacent two cup bodies 6. Furthermore, the rotating support plate drives each cup body 6 to rotate by a certain angle together, ensuring that when the cup body 6 rotates once, it is exactly located at the position where the previous cup body 6 is located. The rotary plunger 12 is used for positioning and restricting the cup body 6.

[0038] The material cleaning assembly includes an electric push rod 13. The electric push rod 13 is vertically arranged directly above the cup body 6 at the material cleaning station. The piston rod of the electric push rod 13 extends from the lower end of the cylinder body. A brush head 14 is fixedly installed at the lower end of the piston rod of the electric push rod 13. The outer diameter of the brush head 14 is the same as the inner diameter of the cup body 6. When the cut tobacco in the cup body 6 rotates to the material cleaning station after passing through the filling value measurement and follows the cup body 6, the piston rod of the electric push rod 13 extends downward, so that the brush head 14 extends into the lower cup body 6, directly pushing the cut tobacco in the cup body 6 downward, enabling the cut tobacco to fall into the lower waste collection bucket 3 through the first blanking hole 4 and the second blanking hole 5. At the same time, the brush head 14 cleans the inner wall of the cup body 6. After that, the piston rod of the electric push rod 13 contracts upward and resets, pulling the brush head 14 out of the cup body 6 and resetting, realizing the recovery of samples while being able to clean the cup body 6.

[0039] The sample recovery and cleaning system of the cut tobacco filling value measurement bucket in this embodiment further includes a partition plate 15. The partition plate 15 is horizontally arranged above each cup body 6. The four sides of the partition plate 15 are fixedly supported on the bottom plate 1 through vertical support plates 22. A first through hole 16 corresponding to the cup body 6 at the material cleaning station up and down is provided on the partition plate 15. An L-shaped fixed support plate 17 located on one side of the first through hole 16 is fixedly installed on the partition plate 15. The upper side plate of the L-shaped fixed support plate 17 is horizontally arranged directly above the first through hole 16. The lower end of the cylinder body of the electric push rod 13 is fixedly installed at the top of the upper side plate of the L-shaped fixed support plate 17. A second through hole corresponding to the first through hole 16 up and down is provided on the upper side plate of the L-shaped fixed support plate 17. The piston rod of the electric push rod 13 passes downward through the second through hole and the first through hole 16. The outer diameter of the brush head 14 is less than or equal to the inner diameter of the first through hole 16.

[0040] The lower surface of the partition plate 15 is fixedly installed with a dust-proof cylinder 18 located directly above the rotary drive plate 9. The dust-proof cylinder 18 is arranged in the middle of each cup body 6. The outer diameter of the dust-proof cylinder 18 is the same as the outer diameter of the rotary drive plate 9. There is a gap between the lower end of the dust-proof cylinder 18 and the upper surface of the rotary drive plate 9. The outer edge of the upper surface of the rotary drive plate 9 is fixedly installed with a polytetrafluoroethylene ring 19 located in the gap.

[0041] The bottom plate 1 is also fixedly connected with a dust-proof ring 20 located directly below the rotary drive plate 9. The dust-proof ring 20 is located in the central hole of the reference plate 2. There is a gap between the upper end of the dust-proof ring 20 and the lower surface of the rotary drive plate 9. The outer circumference of the dust-proof ring 20 is in close contact with the inner circle of the reference plate 2. The dust-proof cylinder 18, the polytetrafluoroethylene ring 19 and the dust-proof ring 20 all play a role in dust prevention, that is, preventing dust from entering the hollow rotary platform 10.

[0042] The reference plate 2 is an annular plate with a round inner and square outer shape. The upper surface of the bottom plate 1 is provided with a square groove adapted to the size of the reference plate 2. The reference plate 2 is fixedly embedded in the square groove, and the upper surface of the reference plate 2 is flush with the upper surface of the bottom plate 1.

[0043] The outer diameter of the rotary drive plate 9 is the same as the inner diameter of the reference plate 2.

[0044] In order to ensure the level of the reference plate 2, a level 21 can be set on the reference plate 2, and the reference plate 2 is adjusted according to the level 21 when adjusting the level.
