Description

Technical Field

[0001] The utility model relates to the technical field of tobacco performance parameter measurement, and specifically, to an environmental cleaning device for a rotary multi-station filling value measuring instrument. Background Art

[0002] A filling value measuring instrument is a special device used to detect materials to be measured such as cut tobacco, expanded cut tobacco, sheeted tobacco, cut stem, expanded cut stem, and finished blended cut tobacco. The process is to put the material to be measured into a measuring cylinder, then apply pressure to the material to be measured from top to bottom, and observe the change in the compression amount of the material to be measured to reflect its filling value.

[0003] When carrying out the automation transformation of the filling value measuring instrument, a solution with multiple operating stations set by means of rotary motion has been developed, which can be used to implement automated cyclic detection. For example, the utility model with the application number CN113834773A and the name: A rapid detection device for cut tobacco filling value adopts this solution.

[0004] However, the position of the measuring cylinder in this solution is fixed, and it can only feed materials but cannot discharge them. The discharging process requires the participation and cooperation of many additional devices, which is not convenient. To solve this problem, the applicant intends to remove the bottom of the measuring cylinder and adopt a sliding and sealing cooperation with the support platform to solve this problem. However, leakage is inevitable during long-term operation, resulting in the retention of tobacco powder and other impurities in the environment, so it is necessary to clean up these impurity pollution situations.

[0005] In order to solve the above existing problems, people have been seeking an ideal technical solution. Content of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art, and thus provide an environmental cleaning device for a rotary multi-station filling value measuring instrument that cleans the environment of the walking path of the measuring cylinder of the filling value measuring instrument to prevent the accumulation of residues.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is: an environmental cleaning device for a rotary multi-station filling value measuring instrument, including a rotary mechanism, a support platform, a plurality of measuring cylinders, and a plurality of cleaning brushes;

[0008] The rotary mechanism is used to drive a plurality of measuring cylinders and a plurality of cleaning brushes to perform circular motion;

[0009] The measuring cylinder is a cylindrical structure with a through top and bottom. The bottom of the measuring cylinder is in sliding and sealing cooperation with the support platform, and a discharge port is arranged on the support platform corresponding to the movement track of the measuring cylinder;

[0010] The measuring cylinder and the cleaning brush are arranged at intervals. The distal end of the lower bristles of the cleaning brush is closely attached to the upper end surface of the support platform. The movement track of the cleaning brush coincides with that of the measuring cylinder, and is used to push and sweep the residues to the discharge port.

[0011] Based on the above, the rotating mechanism includes a rotating motor, a rotating cylinder and a driving plate. The rotating motor drives the rotating cylinder to rotate. The rotating cylinder and the driving plate are fixed. The cleaning brush is installed around the driving plate through a brush connecting arm.

[0012] Based on the above, arc-shaped clamping grooves are arranged around the driving plate, and the measuring cylinder is installed in each arc-shaped clamping groove.

[0013] Based on the above, a flange is arranged on the outer side of the bottom end of the measuring cylinder. A flexible sealing ring is installed at the bottom end of the flange, and the bottom end of the flexible sealing ring is equal to or lower than the bottom end of the measuring cylinder.

[0014] Based on the above, a spinning mechanism is arranged at the notch of the arc-shaped clamping groove, and the spinning mechanism is used to press the flange from top to bottom.

[0015] Based on the above, it further includes a top plate. The top plate and the support platform are connected by side walls to form a semi-closed cavity. The upper end of the cleaning brush is provided with upper bristles, and the distal end of the upper bristles is used to clean the bottom of the top plate.

[0016] Based on the above, a feeding station and a measuring station are arranged on the top plate corresponding to the movement track of the measuring cylinder. A sealing plate is arranged at the bottom end of the bottom plate between the feeding station and the measuring station. The sealing plate is at the same height as the top end of the measuring cylinder and is used to close the top opening of the measuring cylinder. The upper bristles of the cleaning brush are used to clean the sealing plate.

[0017] Based on the above, the cleaning brush includes a main body part, upper bristles and lower bristles arranged at the upper and lower ends of the main body part. A U-shaped groove is arranged in the middle of the main body part. One end of the brush connecting arm is clamped into the U-shaped groove for installation and locked by bolts. The other end of the brush connecting arm is plate-shaped and locked to the outer periphery of the driving plate by bolts.

[0018] The utility model has substantial features and progress compared with the prior art. Specifically, after the measuring cylinder is transformed into a cylindrical structure with a through top and bottom, although the sealing performance between the measuring cylinder and the support platform can be optimized to improve the sealing of the measuring cylinder, the tobacco sample to be measured usually contains a lot of powder, and these powders are likely to escape from the gaps of the sliding sealing structure to the external environment. To avoid the accumulation of these fine powder residues in the external environment, a cleaning brush that moves synchronously with the measuring cylinder is arranged between two adjacent measuring cylinders to clean the support platform. The escaped powder residues are pushed by the cleaning brush through the discharge port and discharged from the discharge port, effectively solving the potential safety and hygiene hazards caused by the accumulation of powder residues.

[0024] The technical solutions of the present utility model will be further described in detail below through specific embodiments.

[0025] As Figures 1-3 shown, an environmental cleaning device of a rotary multi-station filling value measuring instrument includes a rotary mechanism 1, a support platform 2, a plurality of measuring cylinders 3 and a plurality of cleaning brushes 4.

[0026] The rotary mechanism 1 is used to drive the plurality of measuring cylinders 3 and the plurality of cleaning brushes 4 to perform circular motion;

[0027] The measuring cylinder 3 has a cylindrical structure with through top and bottom. The bottom of the measuring cylinder 3 is in sliding and sealing fit with the support platform 2, and a discharge port 21 is provided on the support platform 2 corresponding to the movement track of the measuring cylinder 3.

[0028] The measuring cylinder 3 and the cleaning brush 4 are arranged at intervals. The distal end of the lower bristles 41 of the cleaning brush 4 is closely attached to the upper end surface of the support platform 2, and the movement track of the cleaning brush 4 coincides with the movement track of the measuring cylinder 3, for pushing the residues to the discharge port 21.

[0029] Principle description:

[0030] Based on the requirements of multi-station detection and discharging automation, a rotary structure is set up. The measuring cylinder 3 is driven by rotary motion to switch between different stations to achieve different functions. In this embodiment, it at least includes a feeding station, a measuring station and a discharging station. In this cycle, the material to be measured enters the measuring cylinder and then makes a rotary motion synchronously with the measuring cylinder. Although the sealing performance of the sliding sealing structure at the bottom of the measuring cylinder can be optimized, there is also a balance between cost and performance, resulting in the inability to fully prevent fine tobacco dust particles from escaping from the sliding sealing structure.

[0031] In addition, during this cycle, the top of the measuring cylinder is open, and fine powder is also easy to escape from the open top to the environment and finally accumulate on the support platform.

[0032] To solve the above problems, a cleaning brush 4 is arranged between two adjacent measuring cylinders 3. Both the cleaning brush 4 and the measuring cylinder 3 are installed on the rotary mechanism 1 and make a circular motion synchronously.

[0033] The residues such as powder escaping from the measuring cylinder 3 can be timely swept by the following cleaning brush 4. When the cleaning brush 4 passes through the discharge port 21, the swept powder residues are discharged from the discharge port 21, thus completing the cleaning of the multi-station walking track, eliminating the potential hygiene and safety hazards, and preventing the hygiene problems caused by the accumulation and mildew of the powder.

[0034] Of course, there are inevitably corners in the cleaning and hygiene of this measuring device, and it still needs to be disassembled, washed and maintained regularly. However, the setting of the cleaning brush in this solution can delay the frequency of disassembly, washing and maintenance to a certain extent and reduce the maintenance cost.

[0035] In this embodiment, the rotary mechanism 1 includes a rotary motor (not shown in the figure), a rotary cylinder 12 and a driving plate 13. The rotary motor is installed at the lower end of the support platform. The rotary motor drives the rotary cylinder 12 to rotate. The rotary cylinder 12 and the driving plate 13 are fixed to achieve synchronous rotation. The cleaning brush 4 is installed around the driving plate 13 through a brush connecting arm 44.

[0036] Specifically, in this embodiment, it further includes a top plate 5. The top plate 5 and the support platform 2 are connected by a side wall 6 to form a semi-closed cavity. The upper end of the cleaning brush 4 is provided with upper bristles 42, and the distal end of the upper bristles 42 is used to clean the bottom of the top plate. Corresponding to the movement track of the measuring cylinder, a feeding station and a measuring station are arranged on the top plate 5.

[0037] As Figure 4 shown, to ensure the sealing of the measuring cylinder 3 before measurement, ensure the water sealing effect, and avoid water evaporation, a sealing plate 51 is provided at the bottom end of the bottom plate between the feeding station and the measuring station. The sealing plate 51 is at the same height as the top end of the measuring cylinder 3 and is used to seal the top opening of the measuring cylinder 3. Its material can be selected from materials with sealing properties such as polytetrafluoroethylene. The upper bristles 42 of the cleaning brush 4 are used to clean the sealing plate 51.

[0038] Therefore, in the optimal embodiment, the cleaning brush 4 includes a main body portion 43, upper bristles 42 and lower bristles 41 provided at the upper and lower ends of the main body portion 43. A U-shaped groove is provided in the middle of the main body portion 43. One end of the brush connecting arm 44 is snapped into the U-shaped groove and locked by a bolt. The other end of the brush connecting arm 44 is plate-shaped and locked to the outer periphery of the driving plate 13 by a bolt.

[0039] To achieve the stability of the sliding seal of the measuring cylinder 3, arc-shaped clamping grooves are provided around the driving plate 13, and the measuring cylinder 3 is installed in each arc-shaped clamping groove.

[0040] A flange 31 is provided on the outer side of the bottom end of the measuring cylinder 3. A flexible sealing ring 32 is installed at the bottom end of the flange 31. The bottom end of the flexible sealing ring 32 is equal to or lower than the bottom end of the measuring cylinder 3. In this embodiment, the flexible sealing ring can be made of polytetrafluoroethylene or rubber.

[0041] A spinning mechanism 33 is provided at the notch of the arc-shaped clamping groove. The spinning mechanism 33 is used to press the flange from top to bottom. The spinning mechanism 33 can be a pre-tightening bolt or a pin bolt with a spring, etc.

[0042] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed in the present invention.
