Description

Technical Field

[0001] The invention belongs to the technical field of tipping paper detection, in particular to an online automatic detection system for tipping paper product quality. Background Art

[0002] Tipping paper is a special paper that connects the filter tip to the cigarette stick. Combined with high-transparency forming paper and other technologies, it can effectively reduce the production of tar, nicotine and carbon monoxide in cigarettes, and have a great impact on the characteristics and style of cigarette smoking. Traditional tipping paper testing includes appearance, performance, biology, etc. The instrument is mainly composed of an air permeability meter host, an air source, a voltage stabilizer, a timing device, etc. At the same time, auxiliary tools such as a thickness gauge, a paper cutter, and tweezers are prepared. According to the testing standards for tipping paper, including YC171-2009 "Tipping Paper for Cigarettes" or the tobacco industry standard manual, the technical requirements, test methods, inspection rules and packaging, labeling, etc. for cigarette tipping paper are stipulated. For example, at least 10 circular specimens with a diameter of 30-50 mm should be cut from the tipping paper sample. During the cutting process, the specimens should be protected from wrinkles, damage or contamination. If the testing requirements for tipping paper are low in the early stage of production, the tipping paper sample can be directly held for testing. If the quality test of tipping paper is conducted after production, the tipping paper sample needs to be pre-treated. The sample should be equilibrated in a standard environment with a temperature of 23±2°C and a relative humidity of 50±5% for at least 4 hours to achieve a stable moisture absorption state. The sample should then be transferred or placed in a testing position using a sample container to avoid contamination. Only in this way can the air permeability test of the tipping paper be carried out.

[0003] However, during the balancing process of the tipping paper, operators need to perform tedious operations such as sampling, transfer, and storage, which prolongs the time spent on the pre-processing of the tipping paper test and affects the test efficiency. At the same time, excessive contact will cause the tipping paper samples to be contaminated with grease or absorb more dust. Dust particles may block the air pores of the tipping paper, resulting in low air permeability measurement values. Moreover, the uneven distribution of dust will cause large differences in the air permeability measurement results of different parts, affecting the accuracy and repeatability of the test. In addition, the more times the sample is transferred, the higher the risk of mechanical damage such as wrinkling and stretching during the pre-processing process. This will change its internal structure, cause air permeability deviations, and further affect the air permeability test accuracy of the tipping paper. Summary of the Invention

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings shown in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example 1:

[0044] In order to effectively solve the above problems, as shown in the accompanying drawings of the specification Figures 1-15 As shown, the online automatic detection system for tipping paper product quality includes a main unit 1, an air source, a detection device, and a timing device. The main unit 1 is the main structure of a conventional online automatic detection device for tipping paper air permeability. The air source is a conventional air supply device equipped with the device for the required air filling. The detection device is a conventional air permeability test bench.

[0045] A sample storage box 11 is installed on one side of the host 1, and a channel 12 is provided inside the sample storage box 11. One end of the channel 12 is located on one side of the sample storage box 11, and the other end is located on the other side adjacent to the sample storage box 11. An electric push rod 13 is provided on one side of the corner of the L-shaped channel 12, and a motor 14 is provided on the other side. A convex plate 15 is rotatably connected between the motor 14 and the channel 12, and the motor 14 is connected to one side of the convex plate 15 with a rubber soft connection;

[0046] The sample box 16 slides inside the channel 12. A sample box 16 consists of two half boxes 17. A card rod 18 is slidably connected to one half box 17 by a spring, and a card slot 19 is provided on the other half box 17. Sealing rings 2 are evenly provided on the half box 17 and are close to the inner and outer sides of the half box 17 respectively. An annular cutter 21 is provided between the two sealing rings 2; a groove 22 is provided on one side of the sample box 16 and a convex block 23 is provided on the other side, and the groove 22 is engaged with the protruding part of one side of the convex plate 15; a cover plate 24 is installed in the center of the half box 17, and an air inlet pipe 25 and an air exhaust pipe 26 are symmetrically provided in the half box 17, and the air outlet holes in the air inlet pipe 25 and the air exhaust pipe 26 are inclined toward the center position; an electric telescopic rod 27 is provided in the sample storage box 11, and the telescopic end of the electric telescopic rod 27 rises and falls, driving the gas flow end of the gas source to move and connect the air inlet pipe 25 and the air exhaust pipe 26;

[0047] The rubber flexible connection is used for rubber products that act as flexible connections between metals. For example, the motor 14 drives the transmission shaft to rotate through a rubber block connection, which can absorb the displacement during the rotation of the transmission shaft, that is, the motor 14 absorbs the vibration of the convex plate 15 during rotation through the rubber flexible connection; the electric push rod 13, the electric telescopic rod 27 and the motor 14 are conventional electric drive devices, and the motor 14 is a conventional type that can cycle forward and reverse; the channel 12 is a groove with an L-shaped cross-section. The worker holds the cylindrical sample box 16 and inserts it into the channel 12. When inserting, the two sides of the sample box 16, one side faces the worker, and the other side faces the motor 14. The outer ring surface of the sample box 16 contacts the inner wall of the channel 12 and is restricted by the channel 12, so that when the sample box 16 moves toward the motor 14, the sample box 16 moves in a fixed posture with one side facing the worker and the other side facing the motor 14 until the horizontal groove 22 and the convex plate 15 are engaged with each other, and the convex plate 15 is in a static state at this time; then, when the second sample box 16 is inserted, the groove 22 of the second sample box 16 is engaged with the horizontal protrusion 23 of the first sample box 16 when it is static, and the third sample box 16 is connected in this way; when the sample box 16 is in a static state in the channel 12, the groove 22 and the protrusion 23 are connected with each other, and the groove 22 is in a horizontal state. The telescopic end of the electric telescopic rod 27 drives the gas flow end of the air source to move and connect to the air inlet pipe 25, so that the air source can inflate the interior of the sample box 16 and replace the internal air, thereby adjusting the temperature and humidity of the tipping paper sample and balancing the sample;

[0048] Each half box 17 is provided with an air inlet pipe 25 and an air extraction pipe 26, and ventilation can be achieved in a variety of ways. For example, electric telescopic rods 27 are respectively provided at the top and bottom of the sample box 16. The electric telescopic rod 27 located at the top descends, driving the air supply end of the air source to communicate with the air inlet pipes 25 on the two half boxes 17. The electric telescopic rod 27 located at the bottom rises, driving the air extraction end of the air source to communicate with the air extraction pipes 26 on the half boxes 17, thereby completing the effect of replacing the air inside the sample box 16 and achieving air flow; or the electric telescopic rod 27 is only provided at the top of the sample box 16, and a valve such as a pressure relief valve is provided in the air extraction pipe. When the air filled in the sample box 16 is too high, the air inside the sample box 16 is discharged from the air extraction pipe 26 through the pressure relief valve.

[0049] Specific working process: When no sample is taken, the sample box 16 is separated into two half boxes 17;

[0050] When sampling, the worker places the two half boxes 17 on either side of the tipping paper, and then merges the two half boxes 17. The latching rod 18 on one half box 17 enters the latching groove 19 in the other half box 17. The latching rod 18 and the latching groove 19 are locked with each other, and the sealing rings 2 on the two half boxes 17 contact and overlap and press tightly to maintain the sealing effect between the two half boxes 17. After the sealing rings 2 overlap, the cutter 21 contacts and cuts the tipping paper. Since the cutter 21 is located between the two sealing rings 2, the cut edge of the sample is located in the sealed space between the two sealing rings 2. Impurities such as paper scraps and paper fibers generated during the cutting process are sealed in this space, preventing impurities generated during frequent cutting from floating on the sample surface, interfering with the cleanliness of the sample surface, and affecting the accuracy of the air permeability test.

[0051] Furthermore, even if workers clean the sample surface, manual cleaning is often not uniform, resulting in uneven distribution of impurities on the sample surface. That is, one part of the sample surface may have fewer impurities, while another part may have more. This can cause large differences in the air permeability measurement results of different parts, affecting the accuracy and repeatability of the tipping paper quality test.

[0052] Moreover, after the two half boxes 17 are combined into a sample box 16, the sample is clamped and fixed in the middle. The worker can achieve the purpose of contactless sample transfer through the sample box 16, isolating the contact between the outside world and the sample, reducing the contamination of the sample before testing, and improving the detection accuracy. The clamping and fixing of the sample by the half box 17 can also ensure that the sample is always kept flat during the transfer and testing process, avoiding the occurrence of creases and other errors in the sample, which may cause changes in the internal structure of the sample and affect the sample detection.

[0053] The cam 15 is connected to the plurality of sample boxes 16 when the sampling is finished, and the cam 15 is in a horizontal state when the cam 15 is at rest. Then, the motor 14 drives the cam 15 to rotate through the connection mode of the rubber soft connection. The cam 15 drives the sample box 16 to rotate in the channel 12 through the connection between the cam portion and the groove 22. At the same time, a plurality of balls can be evenly arranged in the channel 12 to reduce the friction generated by the rotation of the sample box 16 in the channel 12, reduce the force required for the motor 14 to drive the cam 15, and reduce the force applied to the rubber soft connection; the motor 14 drives the sample box 16 to rotate forwardly by a certain angle through the cam 15 and then reversely by the same angle. For example, the sample box 16 rotates forward 90 degrees and then reverses 90 degrees. The sample box 16 drives the sample to swing, and the dust on the surface of the sample is thrown off or thrown when the sample is in a flat and upright state, completing the contactless cleaning while keeping the sample flat, avoiding the sample from being damaged during cleaning, resulting in the occurrence of the situation that the detection work is affected, thereby improving the practicality of the online automatic detection system for the quality of the tipping paper product;

[0054] After the sample is swung for a period of time, it stops and the sample box 16 is in a static state. The electric telescopic rod 27 drives the air source to connect the air inlet pipe 25 and the air extraction pipe 26 respectively. The air inlet pipe 25 blows air at an angle toward the sample surface, and the air extraction pipe 26 extracts air into the sample box 16 to remove impurities. This achieves the effect of air flow inside the sample box 16 flushing impurities on the sample surface while improving the cleanliness of the sample surface without contacting the sample, thereby reducing the impact of impurities on the permeability test and improving practicality. In addition, the air inlet pipe 25 blows air at an angle toward the sample surface to prevent the blowing from damaging the sample. At the same time, the air flow is not blocked between the sample and the cover plate 24, thereby improving the air flow flushing effect and the cleaning effect. In addition, the air extraction pipe 26 is located at the bottom of the sample box 16, and impurities fall and gather at the bottom of the sample box 16. The air extraction pipe 26 can remove impurities within a short distance, reducing the flow range of impurities in the sample box 16, avoiding secondary contamination, and improving the cleanliness of the sample box 16. After using the air flow to flush for a period of time, the above-mentioned impurity removal and air flow flushing steps can be repeated multiple times.

[0055] After cleaning is completed, the gas source injects gas for balancing into the sample box 16. Since each tipping paper is located in a separate sample box 16 for balancing, compared with the method of stacking in a constant temperature box in the prior art, the internal space of the sample box 16 is relatively small, and the heat capacity of the internal material is also small. For example, when heating or cooling a small chamber, the amount of heat required to change is relatively small, and the temperature is more likely to change in response to control measures; in contrast, a large chamber contains more material and air and has a larger heat capacity. To change its temperature, a large amount of heat needs to be absorbed or released, which makes the temperature change slower, shortens the balancing time, and reduces the detection time; and, since the small chamber has a smaller space, the heat propagation path therein is relatively short, making it easier to achieve uniform temperature distribution, and can act more evenly on various parts of the sample box 16, reducing local overheating or overcooling, improving the balancing effect, and reducing the impact of balancing problems on detection;

[0056] Moreover, due to the small internal space of the sample box 16, when the sample absorbs or releases water, the water vapor circulates rapidly within the limited space due to the small space, allowing the water vapor exchange between the sample and the surrounding environment to reach equilibrium more quickly. In a larger space, water vapor diffuses over a wider range, and the sample needs longer to influence the large amount of surrounding water vapor to reach an equilibrium state that is compatible with its own moisture content. During the sample equilibrium process, the uniform temperature and humidity environment facilitates the simultaneous and uniform absorption or loss of water by all parts of the sample, thereby shortening the equilibrium time. In contrast, a larger space may have temperature and humidity gradients, and the environments of different parts of the sample may vary slightly, resulting in inconsistent equilibrium processes and prolonged overall equilibrium time. The air circulation in a smaller space is relatively stable, without excessive and complex air flow interference. The stable air environment helps maintain the water vapor boundary layer on the sample surface, making the water exchange process more regular and facilitating faster equilibrium. In contrast, a larger space may have more air flow factors, such as natural convection and ventilation. These airflows will continuously carry away or bring in water vapor, interfering with the equilibrium process between the sample and the surrounding water vapor, resulting in longer equilibrium time. In addition, the sample can be individually balanced through the sample box 16 without being affected by stacking.

[0057] After the sample is balanced, the convex plate 15 and the sample box 16 are in a static state, the protruding part of the convex plate 15 and the groove 22 on the sample box 16 are in a horizontal state, and the ends are facing the channel 12 and the telescopic end of the electric push rod 13. The telescopic end of the electric push rod 13 extends to push the sample box 16 away from the convex plate 15 and move it out of the sample storage box 11 from the other end of the channel 12; when the worker tests the balanced sample, the cover 24 can be removed to expose the sample without touching the sample throughout the process, which reduces the risk of affecting the sample while improving the convenience of use.

[0058] Example 2:

[0059] On the basis of embodiment 1, one side of the cover plate 24 is rotatably connected to a rotating rod 3, and one end of the rotating rod 3 is rotatably connected to a roller 31, a surface of the roller 31 is provided with an adhesive layer, the surface of the roller 31 contacts the inner wall of the half box 17, and a counterweight is provided in the roller 31; one side of the rotating rod 3 is provided with a cloth 1 32, and one side of the cover plate 24 is provided with a cloth 2 33, and the cloth 1 32 contacts the cloth 2 33; one side of the rotating rod 3 is rotatably connected to a rotating shaft 34, and the surface of the rotating shaft 34 is provided with an adhesive layer, and the surface of the rotating shaft 34 contacts the surface of the cloth 2 33; one side of the cover plate 24 is provided with a spike 35, and the spike 35 is facing away from the cloth 2 33; the diameter of the sample box 16 is 30-50 cm. When the sample box 16 is installed and merged, the distance between the outer wall of the half box 17 and the outer wall of the cover plate 24 meets the installation size of the motor. To ensure the rotation of the rotating rod 3, the worker can also install a motor on the cover plate 24, the output end of the motor is connected to the rotating rod 3, and the motor is controlled to rotate by wireless technology;

[0060] The cover plate 24 is evenly provided with baffles 36 on one side, and the baffles 36 are symmetrically distributed. The baffles 36 are located on the side of the second cloth 33 close to the air inlet pipe 25, and the baffles 36 are away from the tipping paper.

[0061] The baffle 36 is arranged obliquely toward the exhaust pipe 26, and a guide plate 37 is evenly arranged on one side of the baffle 36;

[0062] Both cloth one 32 and cloth two 33 are conventional synthetic fiber cloths, which are easy to generate static electricity when rubbing against each other. In addition, when cloth one 32 and cloth two 33 generate static electricity due to frictional contact, the sample is not in a state of equilibrium, and the effect of static electricity generated by friction between cloth one 32 and cloth two 33 will not be affected. Moreover, cloth one 32 and cloth two 33 are located in the internal space of the sample box 16 and generate static electricity due to friction, which is less affected by the humidity of the external environment. The roller 31 increases the weight by adding a counterweight block, etc., thereby increasing the movement inertia of the roller 31 and the rotating rod 3. The roller 31 rolls along the inner wall of the half box 17 to remove impurities, thereby improving the cleanliness of the sample box 16.

[0063] Specific working process: When the sample box 16 rotates the sample forward and backward, the sample box 16 swings the rotating rod 3 and the roller 31. When the sample box 16 switches the rotation direction during the forward and reverse rotation, the rotating rod 3 and the roller 31 are affected by the inertia of the movement and produce reciprocating swings, such as the pendulum on the wall clock swinging back and forth. The rotating rod 3 drives the cloth 1 32 to rub the cloth 2 33, so that static electricity is generated on the cloth 2 33 due to friction. Since most of the impurities on the sample are light impurities such as paper scraps and paper fibers, they are easily adsorbed by static electricity. The cloth 2 33 uses the static effect to adsorb the impurities on the surface of the sample on its surface, improving the cleaning efficiency while avoiding contact. The rotating rod 3 drives the rotating shaft 34 to swing, and the surface of the rotating shaft 34 contacts the second cloth 33 through the viscose layer, so that the rotating shaft 34 rolls on the surface of the second cloth 33. The rotating shaft 34 uses the viscose layer to remove impurities adsorbed on the surface of the second cloth 33, thereby improving the adsorption capacity of the second cloth 33 and preventing the surface of the second cloth 33 from adsorbing too many impurities that affect the adsorption capacity. In addition, when the rotating rod 3 stops swinging, the electrostatic effect of the second cloth 33 is reduced. Since the impurities adsorbed on the second cloth 33 have been removed by the adhesion of the rotating shaft 34, the self-cleaning work is completed, thereby improving the cleanliness of the sample box 16 and preventing the sample from being contaminated by secondary contamination.

[0064] Furthermore, before taking samples, workers will test the temperature and humidity of the tipping paper. If the temperature and humidity differ greatly from the indicators, the sample needs to extend the balancing time. If the temperature and humidity differ little from the indicators, the sample can be balanced for a shorter time. Therefore, after cleaning is completed and the balance is entered, the motor 14 is used to indirectly drive the rotating rod 3 to swing again. The rotating rod 3 stirs the air inside the sample box 16, drives the air flow around the sample, promotes the continuous renewal of the air, makes it easier for water vapor in the environment to reach the sample surface, and the moisture on the sample surface is also easier to diffuse into the environment, thereby accelerating the humidity balance speed of the sample.

[0065] Furthermore, the stirring of the rotating rod 3 enhances air flow, which helps transfer heat between the sample and the surrounding environment. During the equilibrium process, the sample may experience heat changes due to the absorption or loss of water. By accelerating heat exchange, the sample temperature can be more quickly aligned with the ambient temperature, thus avoiding changes in moisture state and instability in the equilibrium process caused by temperature differences.

[0066] Moreover, the stirring of the rotating rod 3 can also fully mix the air around the sample, ensuring that the humidity, temperature and other conditions in the environment are more uniform and consistent at all locations around the sample. This can avoid local differences that lead to different equilibrium speeds in different parts of the sample, so that the entire sample can reach a more uniform and accurate equilibrium state. For example, if there is no stirring, the sample on the side close to the air inlet pipe 25 may absorb water faster due to the high water vapor concentration in the surrounding area, while the other side may absorb water slower, resulting in uneven sample humidity.

[0067] Then, after stirring for a period of time, the motor 14 drives the sample box 16 to rotate back and forth significantly through the convex plate 15, so that the swing amplitude of the rotating rod 3 increases. When the rotating rod 3 drives the cloth 1 32 to swing forward and pass through the spike 35 and then reverse, the inclined spike 35 penetrates into the cloth 1 32, thereby fixing the rotating rod 3 by inserting into the cloth 1 32;

[0068] When the air is blown out through the air inlet pipe 25, its kinetic energy is large, and with the sample in a vertical state, it is easy to blow impurities off. When the air flows close to the exhaust pipe 26, its kinetic energy is weaker and it is not easy to blow impurities away. This makes the effect of the impurity removal on the sample different. By providing the baffle 36, when the air from the air inlet pipe 25 blows into the exhaust pipe 26 and passes through the baffle 36, the baffle 36 blocks the air flow, reducing the cross-sectional area of the air flow. According to the effect of the narrow tube effect, the air flow is accelerated when passing through the cloth 2 33, increasing the kinetic energy of the air, improving the impurity removal effect, and improving the uniformity of the air flushing the sample. When the air is accelerated to flow through the surface of the cloth 2 33, it can also blow away impurities on the surface of the cloth 2 33, improving the cleanliness of the surface of the cloth 2 33 and maintaining its working capacity. When the air flows in a fixed direction in the sample box 16, since the inner wall of the sample box 16 is curved, dead corners are reduced, and impurities are blown by the air along the curved inner wall of the sample box 16 into the suction pipe, preventing impurities from floating and accumulating in the dead corners inside.

[0069] By evenly arranging the guide plates 37, the air is evenly separated by the guide plates 37 when contacting the baffles 36, and then the air between adjacent guide plates 37 contacts the baffles 36 again, thereby improving the uniformity of air flow between the fabric 2 33 and the sample, improving the uniformity of impurity removal, and reducing the impact of uneven impurity removal on air permeability testing.

[0070] Example 3:

[0071] On the basis of the second embodiment, the sample storage box 11 is provided with a vibration block 38, and the top of the vibration block 38 is arc-shaped; the outer edge surface of the sample box 16 is evenly provided with a wavy vibration groove 39, and the top of the vibration block 38 extends into the vibration groove 39;

[0072] A pressing rod 4 is provided on one side of the convex plate 15, and a pressing plate 41 is slidably connected to the pressing rod 4, and the sample box 16 is located between the pressing plate 41 and the convex plate 15; the pressing rod 4 is a conventional long-rod bolt fastener, and a threaded hole is provided on the convex plate 15. After one end of the pressing rod 4 passes through the pressing plate 41 and the edge of the sample box 16, it is screwed into the threaded hole, fixing the sample box 16 on the convex plate 15 and moving with it;

[0073] The sample box 16 is evenly provided with rubber rings 42 , and the rubber rings 42 are located at the mutually inserted connecting portion of the two air inlet pipes 25 and the mutually inserted connecting portion of the two air extraction pipes 26 in one sample box 16 .

[0074] Specific working process: During the forward and reverse rotation of the sample box 16, the sample box 16 drives the vibration groove 39 to reciprocate through the vibration block 38, causing the sample box 16 to vibrate. The sample box 16 drives the sample to vibrate, and the impurities on the vertical sample are shaken off by the vibration. In combination with the electrostatic adsorption effect of the second cloth 33, on the one hand, the cleaning efficiency is improved, and on the other hand, the light impurities are adsorbed by the second cloth 33 and collected by the rotating shaft 34, while the heavy ones fall into the exhaust pipe 26 at the bottom of the sample box 16, reducing the effect of impurity drifting. The sample box 16 drives the convex plate 15 to rotate, and the convex plate 15 absorbs vibration through the rubber flexible connection.

[0075] When installing the sample box 16, first loosen the pressing rod 4 until the pressing rod 4 is disengaged from the convex plate 15, then remove the pressing plate 41, put the sample box 16 into the channel 12 and match the groove 22 with the convex block 23, and then reinstall the pressing plate 41 back on the pressing rod 4. After one end of the pressing rod 4 passes through the pressing plate 41 and the edge of the sample box 16, screw it into the threaded hole of the convex plate 15, and fix the sample box 16 on the convex plate 15, completing the connection of multiple sample boxes 16. When you need to take out the sample box 16, remove the pressing rod 41. By tightening the rod 4, the sample box 16 can slide on the protruding part of the convex plate 15, and the telescopic end of the electric push rod 13 drives the sample box 16 to move, and pushes it out along the channel 12 toward the telescopic end of the electric push rod 13, and then re-tightens the clamping rod 4, which is convenient for installation and removal and improves the convenience of use; and the clamping rod 4 passes through the edge of the sample box 16, on the one hand, it will not interfere with the internal operation of the sample box 16, and on the other hand, it prevents the clamping rod 4 from excessively contacting the inner wall surface of the channel 12 and affecting the rotation of the sample box 16 in the channel 12;

[0076] When the two half boxes 17 are merged, the air inlet pipe 25 on one half box 17 is inserted into the air inlet pipe 25 on the other half box 17 and sealed by the rubber ring 42, and the exhaust pipe 26 is also connected in the above manner; when sampling, the two half boxes 17 need to be merged. Before the two half boxes 17 are merged, the two air inlet pipes 25 and the exhaust pipe 26 first pierce through the tipping paper and then merge to perform sampling. After the air inlet pipe 25 and the exhaust pipe 26 penetrate the tipping paper, the tipping paper is fixed and flattened by the air inlet pipe 25 and the exhaust pipe 26, which facilitates sampling of the sample box 16 and avoids the tipping paper from being bent or folded to damage the sample structure during the sampling process; in addition, the exhaust pipe 26 and the air inlet pipe 25 can also assist in the merging of the half boxes 17, improve the convenience of use, and avoid repeated sampling due to sampling failure.

[0077] Example 4:

[0078] On the basis of the third embodiment, a vent tube 43 is provided on the cover plate 24, and air bags 44 are provided at both ends of the vent tube 43. One air bag 44 is located inside the sample box 16 and the other is located outside the sample box 16. The two air bags 44 have the same volume and material, and the gas storage capacity in the two air bags 44 reaches a balanced state. The parameters such as the material and size of the air bags 44 are the same.

[0079] A screen 45 is provided on one side of the cover plate 24, and the screen 45 is located on both sides of the tipping paper sample, and the screen 45 is close to the tipping paper;

[0080] A sealing piece 46 is connected to the half box 17 through a spring sliding connection. The sealing piece 46 contacts the exhaust pipe 26 and is used to close the exhaust pipe 26. A sealing block 47 is connected to the inner wall of the half box 17 through a spring sliding connection. The inclined surface of one side of the sealing block 47 contacts one end of the sealing piece 46.

[0081] Specific work flow: workers inject air at normal pressure into one half box 17 and inject air slightly higher than normal pressure into the other half box 17. High-pressure and low-pressure environments are formed on both sides of the sample in the sample box 16, so that the gas on both sides of the sample permeates from high pressure to low pressure. The airbag 44 detects the pressure changes on both sides of the sample, that is, the volume of the airbag 44 in the high-pressure environment inside the sample box 16 is reduced due to the high pressure, and the volume of the external airbag 44 expands. When the high-pressure environment is released, the connection between the inner and outer airbags 44 of the high-pressure environment inside the sample box 16 is restored through the ventilation tube 43. In this process, the time it takes for the airbag 44 to expand and recover can be used to predict the air permeability of the sample. If the airbag 44 in the expanded state recovers in a short time, it means that there are major defects in the tipping paper sample, and there is no need to perform air permeability testing. In this simple way, samples that fail sampling can be screened out in advance, thereby improving sample detection efficiency and convenience of use.

[0082] For example, after assembling the sample box 16, a worker injects air at normal pressure into one half of the box 17 and air at a slightly higher pressure than normal pressure into the other half of the box 17, then waits for a preset time. If the airbag 44 does not recover within the specified time, the sample is successfully collected and placed in the sample storage box 11 for subsequent operations. If the airbag 44 recovers within the specified time, the sample is unsuccessful and a new sample is collected.

[0083] By providing a wire mesh 45, the wire mesh 45 is located on both sides of the tipping paper, and the wire mesh 45 and the cover plate 24 are connected by metal. During the pre-test process, the sample will be squeezed to a slight deformation by the high-pressure environment inside the sample box 16. The wire mesh 45 limits the deformation range of the sample to prevent the sample from being damaged by excessive deformation. Moreover, if the sample deforms and contacts the wire mesh 45, the wire mesh 45 is connected to the cover plate 24, and the wire mesh 45 guides and eliminates the static electricity in the sample, thereby reducing the static electricity generated during the sample sampling process and preventing the sample from absorbing impurities due to static electricity. In addition, the wire mesh 45 can be selected as a striped type, that is, the iron wires in the wire mesh 45 face the same direction, so as to prevent the wire mesh 45 from blocking the air flow inside the sample box 16.

[0084] When the rotating rod 3 swings greatly to complete the fixing work, the rotating rod 3 rolls and squeezes the sealing block 47 through the roller 31, and the inclined surface on one side of the sealing block 47 squeezes one end of the sealing piece 46. The sealing piece 46 moves to close the exhaust pipe 26, and the impurities remaining in the exhaust pipe 26 are sealed inside the exhaust pipe 26, so as to prevent the impurities inside the exhaust pipe 26 from drifting back into the sample box 16 and causing secondary contamination of the sample.
