Description

Technical Field

[0001] This invention belongs to the field of detection device technology, specifically relating to a cigarette holder rubbing detection device and its usage method. Background Technology

[0002] With social development, in the tobacco industry, consumers not only have higher requirements for the taste of cigarettes themselves, but also for various other aspects of a cigarette's appearance, which also affect their opinion on a cigarette.

[0003] According to feedback from our social survey, some consumers squeeze and rub the cigarette filter while smoking, evaluating its rebound as a measure of cigarette quality. If, after applying considerable force and squeezing and rubbing the filter, the diameter of the filter differs significantly from its original size, the user will perceive this as a quality issue, severely impacting their evaluation of the cigarette's quality.

[0004] In our tobacco industry, this issue has not been given enough attention in the past. Even when cigarettes are shipped out of the factory, the cigarette holders are tested. Due to the lack of relevant equipment, the testing is done manually. Workers squeeze and rub the cigarette holders by hand to evaluate whether they are qualified. However, since different people have different strengths, the judgment of whether they are qualified depends entirely on experience, and the test results are unreliable. Summary of the Invention

[0005] The purpose of this invention is to provide a cigarette holder kneading detection device and its usage method. Through the cooperation of a physical property testing platform, a support mechanism, a motion mechanism and a squeezing mechanism, a constant squeezing and kneading force is applied to the cigarette holder. The deformation of the cigarette holder before and after squeezing and kneading is detected, and the quality of the cigarette holder is determined based on the data. The detection results are highly reliable.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A cigarette holder crumpling detection device includes a physical property testing platform and a mounting frame. The physical property testing platform includes a platform body, a lifting arm, a mounting arm, and a pressure detection head. The physical property testing platform is connected to a height measuring mechanism for monitoring the lifting height of the mounting arm. The mounting frame is mounted on the platform body, and a placement platform is mounted on the mounting frame. The placement platform is equipped with a support mechanism, a motion mechanism, and a squeezing mechanism. The support mechanism is used to support the cigarette, the motion mechanism is used to drive the support mechanism to reciprocate, and the squeezing mechanism is used to squeeze the cigarette holder.

[0008] Furthermore, the support mechanism includes a horizontal column that is laterally slidably mounted on the placement platform, and the upper part of the cross-section of the horizontal column is arc-shaped. This structural design, with the arc-shaped upper horizontal column simulating finger support of the cigarette, results in higher detection accuracy.

[0009] Further defining the motion mechanism, it includes a first slide rail and a motor fixedly mounted on the placement platform. A first groove is formed on the lower end face of the horizontal column, allowing it to slide slidably on the first slide rail via the first groove. A connecting block is fixedly mounted on the power output end of the motor, and a rotating shaft is mounted on the connecting block. The power output shaft of the motor is parallel to and does not overlap with the rotating shaft. A secondary block is fixedly mounted on one end of the horizontal column, and the horizontal column and secondary block are integrally formed in a T-shape. A first slot is formed on the secondary block, and the rotating shaft passes through the first slot. This structural design, through the rotation of the motor and the eccentric setting of the rotating shaft, can drive the horizontal column to move back and forth, thereby coordinating the sliding connection between the horizontal column and the first slide rail, and the squeezing mechanism to squeeze the cigarette mouthpiece, completing the squeezing and kneading of the cigarette mouthpiece. The structure is simple and easy to use.

[0010] Further specifying, the extrusion mechanism includes a pressure roller, with sleeves vertically fixedly installed at both ends of the pressure roller. Two guide rods are vertically fixedly installed on the placement platform, with the sleeves fitted onto the guide rods. A pressure block is installed on the pressure roller. This structural design, through the cooperation of the sleeves and guide rods, utilizes the gravity of the pressure roller and pressure block to extrude force onto the cigarette mouthpiece, ensuring that the pressure remains constant during the extrusion and kneading of the cigarette mouthpiece.

[0011] Furthermore, the pressure block is detachably mounted on the pressure roller. This structural design allows for adjustment of the pressure applied to the cigarette by replacing pressure blocks of different weights during actual use, thus broadening its adaptability.

[0012] Furthermore, a second slide rail is fixedly installed on the placement platform. The first and second slide rails are parallel. A support frame is installed on the crossbar. A second groove is formed on the lower end face of the free end of the support frame. The free end of the support frame is slidably mounted on the second slide rail through the second groove. This structural design, by supporting the free end of the cigarette with the support frame, can prevent the free end of the cigarette from sagging.

[0013] Furthermore, a U-shaped limiting frame is installed on the upper surface of the free end of the support frame. This structural design, by limiting the free end of the cigarette with the U-shaped limiting frame, can prevent the cigarette from curling up during the squeezing and kneading process.

[0014] Furthermore, a limiting frame is installed on the placement platform. The limiting frame is V-shaped, and a limiting plate is fixedly installed at the end of the limiting frame away from the horizontal column. This structural design, through the V-shaped limiting frame, can center the position of the cigarette placed on the horizontal column, so that when the pressure testing head of the physical property testing platform presses down, it can press precisely onto the cigarette. The limiting plate further limits the axial position of the cigarette, ensuring that when the mouthpiece of the same specification of cigarette is squeezed and rubbed, the squeezing and rubbing position is the same, improving the testing accuracy.

[0015] Further specifying, a slide block is fixedly installed on the placement platform, and the limiting frame is slidably installed on the slide block. A top plate is fixedly installed on the end of the slide block near the horizontal column. With this structural design, the limiting frame is slidably installed on the placement platform; when needed, it can be slid to the corresponding position, and after use, the limiting frame can be pulled out, making it more convenient to use. The top plate limits the maximum movement of the limiting frame towards the horizontal column. When positioning a cigarette, simply push the limiting frame to the position where it rests against the top plate to complete the positioning of the cigarette, making it even more convenient to use.

[0016] The present invention also discloses a method for using a cigarette holder rubbing detection device, comprising the following steps:

[0017] 1) Install the mounting bracket onto the platform;

[0018] 2) Without placing the extrusion mechanism on the support mechanism, place the cigarette on the support mechanism so that the mouthpiece of the cigarette is directly below the pressure detection head. The lifting arm of the physical property testing platform drives the installation arm to descend at a constant speed so that the pressure detection head presses on the mouthpiece of the cigarette.

[0019] 3) The pressure detection head continues to descend, squeezing the mouthpiece of the cigarette. Record the downward pressure distance A of the mounting arm when the pressure detection head detects the pressure.

[0020] 4) After recording, the pressure detection head is reset by lifting the lifting arm, and then the squeezing mechanism is installed on the placement platform so that the free end of the cigarette mouthpiece is located between the two support mechanisms and the squeezing mechanism, so that the cigarette mouthpiece is squeezed.

[0021] 5) Activate the motion mechanism to drive the support mechanism to reciprocate, and rub the cigarette mouthpiece while it is being squeezed;

[0022] 6) After kneading for a certain period of time, remove the squeezing mechanism and place the cigarette mouthpiece back into the middle of the support mechanism;

[0023] 7) The lifting arm of the physical property testing platform drives the installation arm to descend at a constant speed until the pressure testing head presses down on the mouthpiece of the cigarette again;

[0024] 8) The pressure detection head continues to descend, squeezing the mouthpiece of the cigarette. Record the downward pressure distance B of the mounting arm when the pressure detection head detects the pressure.

[0025] 9) Compare the pressure distance A and pressure distance B. The height difference between pressure distance A and pressure distance B is the deformation of the cigarette mouthpiece after it has been subjected to the pressure corresponding to the design data and then rubbed. This deformation can be used to determine the recovery ability of the cigarette mouthpiece after being subjected to the pressure corresponding to the design data and then rubbed. If the height difference is within the error range, it is judged as qualified; otherwise, it is judged as unqualified.

[0026] The invention employing the above technical solution has the following advantages:

[0027] 1. Through the cooperation of the physical property testing platform, support mechanism, motion mechanism and extrusion mechanism, a constant extrusion and kneading force is applied to the cigarette mouthpiece. The deformation of the mouthpiece before and after extrusion and kneading is detected. The quality of the mouthpiece is determined based on the data. The test results are highly reliable.

[0028] 2. By rotating the motor and using the eccentric setting of the rotating shaft, the horizontal column can be driven to move back and forth, thereby cooperating with the sliding connection between the horizontal column and the first slide rail, and the squeezing mechanism to squeeze the mouthpiece of the cigarette, thus completing the squeezing and kneading of the mouthpiece of the cigarette. The structure is simple and easy to use.

[0029] 3. By cooperating with the sleeve and guide rod, the pressure roller and pressure block are used to squeeze the cigarette mouthpiece, ensuring that the pressure remains unchanged during the process of squeezing and kneading the cigarette mouthpiece.

[0030] 4. The U-shaped limiting frame restricts the free end of the cigarette, preventing the cigarette from curling up during the squeezing and kneading process;

[0031] 5. The V-shaped limiting frame can center the cigarette on the horizontal column, so that the pressure testing head of the physical property testing platform can press down and squeeze the cigarette. The limiting plate further limits the axial position of the cigarette, ensuring that the squeezing and kneading position is the same when squeezing and kneading the mouthpiece of the same specification of cigarette, thus improving the testing accuracy.

[0048] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0049] like Figures 1 to 7 As shown, a cigarette holder rubbing detection device of the present invention includes a physical property testing platform 1 and a mounting frame 2. The physical property testing platform 1 includes a platform body 11, a lifting arm 12, a mounting arm 13 and a pressure detection head 14. The physical property testing platform 1 is connected to a height measuring mechanism for monitoring the lifting height of the mounting arm 13. The mounting frame 2 is mounted on the platform body 11, and a placement platform 3 is mounted on the mounting frame 2. The placement platform 3 is equipped with a support mechanism, a motion mechanism and a squeezing mechanism. The support mechanism is used to support the cigarette stick 10, the motion mechanism is used to drive the support mechanism to reciprocate, and the squeezing mechanism is used to squeeze the cigarette holder of the cigarette stick 10.

[0050] The support mechanism includes a horizontal column 41, which is slidably mounted on the placement platform 3. The upper part of the cross-section of the horizontal column 41 is arc-shaped. The arc-shaped upper part of the horizontal column 41 simulates the support of a finger on the cigarette 10, resulting in higher detection accuracy.

[0051] The motion mechanism includes a first slide rail 51 and a motor 5 fixedly mounted on the placement platform 3. A first groove is formed on the lower end face of the horizontal column 41, through which the horizontal column 41 is slidably mounted on the first slide rail 51. A connecting block 501 is fixedly mounted on the power output end of the motor 5, and a rotating shaft 502 is mounted on the connecting block 501. The power output shaft of the motor 5 is parallel to and does not coincide with the rotating shaft 502. A secondary block 511 is fixedly mounted on one end of the horizontal column 41. The horizontal column 41 and the secondary block 511 are integrally formed in a T-shape. A first slot 512 is formed on the secondary block 511, and the rotating shaft 502 passes through the first slot 512. Through the rotation of the motor 5, and utilizing the eccentric setting of the rotating shaft 502, the horizontal column 41 can be driven to reciprocate, thereby coordinating the sliding connection between the horizontal column 41 and the first slide rail 51, and the squeezing mechanism squeezing the mouthpiece of the cigarette 10, thus completing the squeezing and kneading of the mouthpiece of the cigarette 10. The structure is simple and easy to use.

[0052] The extrusion mechanism includes a pressure roller 61, with sleeves 62 vertically fixed at both ends of the pressure roller 61. Two guide rods 63 are vertically fixed on the placement platform 3, with the sleeves 62 fitted onto the guide rods 63. A pressure block 30 is installed on the pressure roller 61. Through the cooperation of the sleeves 62 and the guide rods 63, the pressure roller 61 and the pressure block 30 are used to extrude force onto the mouthpiece of the cigarette 10, ensuring that the pressure remains constant during the process of extruding and kneading the mouthpiece of the cigarette 10.

[0053] The pressure block 30 is detachably mounted on the pressure roller 61. In actual use, the pressure applied to the cigarette 10 can be adjusted by replacing the pressure block 30 with one of different weights, thus adapting to a wider range of applications.

[0054] A second slide rail 52 is also fixedly installed on the placement platform 3. The first slide rail 51 and the second slide rail 52 are parallel. A support frame 42 is installed on the cross column 41. A second groove 420 is opened on the lower end face of the free end of the support frame 42. The free end of the support frame 42 is slidably installed on the second slide rail 52 through the second groove 420. The support frame 42 supports the free end of the cigarette 10, which can prevent the free end of the cigarette 10 from sagging.

[0055] A U-shaped limiting frame 43 is installed on the upper surface of the free end of the support frame 42. The U-shaped limiting frame 43 limits the free end of the cigarette 10, which can prevent the cigarette 10 from curling up during the squeezing and kneading process.

[0056] A limiting frame 7 is also installed on the placement platform 3. The limiting frame 7 is V-shaped, and a limiting plate 72 is fixedly installed at the end of the limiting frame 7 away from the horizontal column 41. The V-shaped limiting frame 7 can center the position of the cigarette 10 on the horizontal column 41, so that when the pressure detection head 14 of the physical property testing platform 1 is pressed down, it can be pressed onto the cigarette 10. The limiting plate 72 further limits the axial position of the cigarette 10, ensuring that when the mouthpiece of the same specification of cigarette 10 is squeezed and rubbed, the squeezing and rubbing position is the same, thus improving the detection accuracy.

[0057] A slide block 73 is fixedly installed on the placement platform 3, and a limiting frame 7 is slidably installed on the slide block 73. A top plate 74 is fixedly installed on the end of the slide block 73 near the horizontal column 41. The limiting frame 7 is slidably installed on the placement platform 3. When needed, it can be slid to the corresponding position. After use, the limiting frame 7 can be pulled out for easier use. The top plate 74 limits the maximum movement of the limiting frame 7 towards the horizontal column 41. When positioning the cigarette 10, the limiting frame 7 can be pushed directly to the position where it rests against the top plate 74 to complete the positioning of the cigarette 10, making it more convenient to use.

[0058] The method of using the cigarette holder rubbing detection device according to this embodiment includes the following steps:

[0059] 1) Install the mounting bracket 2 onto the platform 11;

[0060] 2) Without placing the compression mechanism on the support mechanism, place the cigarette 10 on the support mechanism so that the mouthpiece of the cigarette 10 is directly below the pressure detection head 14 (e.g., Figure 7As shown, the lifting arm 12 of the physical property testing platform 1 drives the mounting arm 13 to descend at a constant speed, so that the pressure detection head 14 presses on the mouthpiece of the cigarette 10.

[0061] 3) The pressure detection head 14 continues to descend, squeezing the mouthpiece of the cigarette 10, and the downward pressure distance A of the mounting arm 13 when the pressure detection head 14 detects the pressure is recorded;

[0062] 4) After recording is completed, the pressure detection head 14 is reset by the lifting arm 12, and then the compression mechanism is installed on the placement platform 3, so that the free end of the cigarette mouthpiece of the cigarette 10 is located between the two support mechanisms and the compression mechanism, so that the cigarette mouthpiece of the cigarette 10 is compressed (e.g., Figure 1 and Figure 2 (as shown);

[0063] 5) Start the motion mechanism to drive the support mechanism to reciprocate. While the mouthpiece of cigarette 10 is being squeezed, the mouthpiece of cigarette 10 is being rubbed.

[0064] 6) After kneading for a certain period of time, remove the squeezing mechanism and place the mouthpiece of cigarette 10 back into the middle of the support mechanism (e.g., Figure 7 (as shown);

[0065] 7) The lifting arm 12 of the physical property testing platform 1 drives the installation arm 13 to descend at a constant speed until the pressure detection head 14 presses down on the mouthpiece of the cigarette 10 again.

[0066] 8) The pressure detection head 14 continues to descend, squeezing the mouthpiece of the cigarette 10, and the downward pressure distance B of the mounting arm 13 when the pressure detection head 14 detects the pressure is recorded.

[0067] 9) Compare the downward pressure distance A and the downward pressure distance B. The height difference between the downward pressure distance A and the downward pressure distance B is the deformation of the cigarette mouthpiece of cigarette 10 after being subjected to the pressure corresponding to the design data and being rubbed. Through this deformation, the recovery ability of the cigarette mouthpiece of cigarette 10 after being subjected to the pressure corresponding to the design data and being rubbed can be judged. If the height difference is within the error range, it is judged as qualified; otherwise, it is judged as unqualified.

[0068] The foregoing has provided a detailed description of a cigarette holder rubbing detection device and its usage method provided by the present invention. The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
