Description

Technical Field

[0001] The present application relates to the technical field of tobacco quality detection, and in particular to tobacco quality detection equipment and methods. Background Art

[0002] During cigarette production, the effective removal of impurities such as stems and puffs plays a critical role in ensuring cigarette quality. If these impurities remain in the tobacco, they can easily lead to serious quality issues such as punctured, empty, and broken cigarettes, significantly impacting the consumer's smoking experience and product reputation. Therefore, in actual cigarette production, stems and puffs must be removed as much as possible to ensure the quality of the finished cigarettes.

[0003] In related technologies, the traditional approach to determining tobacco quality relies on manual sampling. Specifically, in one testing method, an operator extracts a tobacco sample, manually removes and weighs impurities such as stems, and calculates the ratio of the removed impurities to the total sample mass to determine whether the stems and other impurities have been removed. In another testing method, an operator visually inspects or manually touches the tobacco to detect the number of stems and other impurities in the tobacco, thereby determining whether the removal of these impurities has been completed.

[0004] However, all of the above judgment methods require manual subjective judgment on the presence of stem tags. However, since different inspectors have different judgment standards for stem tags, the measurement results are unstable and have low accuracy, and cannot accurately provide effective quality feedback for the production process. Summary of the Invention

[0005] Based on this, it is necessary to provide a tobacco quality detection device and method for improving the detection accuracy in tobacco quality detection.

[0014] Calculating the tobacco density corresponding to the volume data and the weight data according to a second preset relationship;

[0015] When the density of the tobacco shreds is greater than or equal to a preset density, the quality of the tobacco shreds is judged to be qualified;

[0016] Otherwise, the quality of the tobacco is judged to be unqualified.

[0017] The above-mentioned tobacco quality inspection device and method, in this embodiment, uses weight and optical inspection components to automatically collect weight and height data and calculate tobacco density, thereby improving the accuracy of tobacco quality inspection and providing good data support for impurity removal, thereby enhancing the quality of impurity removal. Furthermore, compared with traditional manual inspection methods, this method improves inspection efficiency and reduces errors caused by manual inspection, thus enhancing the reference value of tobacco quality judgment.

DETAILED DESCRIPTION

[0032] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0033] like Figure 1 as well as Figure 2 As shown, the present application provides a tobacco quality detection device 100 , which includes a carrying component 110 , a weight detection component 120 , an optical detection component 130 and a control component 140 .

[0034] The weight detection assembly 120 is mounted on the support assembly 110. The weight detection assembly 120 includes a weight detection element 122 and a weighing carrier 121. The weighing carrier 121 is provided with a weighing chamber 1211. The weight detection element 122 is used to obtain weight data of the tobacco pile within the weighing chamber 1211. In this embodiment, the weighing carrier 121 can be used to load waste tobacco from the tobacco removal process. This waste tobacco includes stems, puffs, and the like. When loaded within the weighing chamber 1211, the waste tobacco forms a tobacco pile.

[0035] The optical detection component 130 is mounted on the supporting assembly 110. The optical detection component 130 is used to detect the height data of the tobacco pile.

[0036] Control component 140 is in communication with weight detector 122 and optical detector 130. Control component 140 receives weight and height data, calculates the tobacco density of the tobacco pile based on the weight and height data, compares the tobacco density with a preset density, and determines that the tobacco is of acceptable quality when the tobacco density is greater than or equal to the preset density. Control component 140 may be a programmable logic controller (PLC), a microcontroller (MCU), an industrial personal computer (IPC), or the like, without further limitation.

[0037] Specifically, the tobacco quality detection device 100 is as follows: Figure 3 As shown, it can be applied to implement an impurity removal detection method.

[0038] Tobacco quality testing methods include:

[0039] S100 , obtaining weight data of the tobacco pile in the weighing cavity 1211 provided in the weighing carrier 121 , obtaining the bottom area of ​​the weighing cavity 1211 , and obtaining height data of the tobacco pile.

[0040] In one example, the bottom area can be obtained by obtaining the bottom area of ​​the weighing cavity 1211 in the weighing carrier 121 from a storage device. In another example, the bottom area can be obtained by obtaining the bottom area of ​​the tobacco pile using the optical detection element 130. In yet another example, the bottom area can be obtained by manual measurement.

[0041] The height data may be, but is not limited to, any one of the highest height, the lowest height, and the average height in the tobacco pile.

[0042] S200: Calculate and obtain volume data corresponding to the height data and the bottom area according to a first preset relationship.

[0043] S300: Calculate the tobacco density corresponding to the volume data and the weight data according to the second preset relationship.

[0044] S400: Determine whether the density of the tobacco shreds is greater than or equal to a preset density.

[0045] It's understandable that impurities like stems and puffs are generally heavier but smaller in volume, meaning their density is higher than that of normal tobacco. Therefore, a higher density in the tobacco pile indicates a higher proportion of stems and puffs in the waste tobacco, which in turn indicates higher tobacco quality. Based on this, when the tobacco density is greater than or equal to the preset density, it indicates that there is little normal tobacco in the waste tobacco pile and more stems. In this case, the tobacco quality is better (i.e., the removal of stems and other impurities in the tobacco is more effective, with most or even all of them removed), and no adjustments to the impurity removal process are required.

[0046] When the tobacco density is less than the preset density, the tobacco is judged to be of unqualified quality. Similarly, when the tobacco density is less than the preset density, it means that there is more normal tobacco in the tobacco pile, and the waste tobacco needs to be re-piled for screening and filtering to avoid excessive loss of normal tobacco.

[0047] To facilitate understanding, the tobacco quality detection method is described in detail below with reference to some implementation scenarios.

[0048] In one implementation scenario, let weight data be M; let volume data be V, height data be h; and tobacco density be ρ.

[0049] There is a preset relationship so that ; a and b are correction coefficients.

[0050] ; c and d are correction coefficients.

[0051] In one example, the shape of the tobacco pile is a rectangular parallelepiped. In this case, the height data may refer to the average height of the tobacco pile, with a=1 and b=0.

[0052] In another example, the shape of the tobacco pile is a cone. In this case, the height data may refer to the highest height of the tobacco pile. , b=0.

[0053] Thus, the tobacco quality inspection device 100 in this embodiment, through the weight detection element 122 and the optical detection element 130, can automatically collect weight and height data and calculate tobacco density, thereby improving the accuracy of tobacco quality inspection, providing good data support for tobacco quality during the impurity removal process, and facilitating improved impurity removal quality. Furthermore, compared with traditional manual inspection methods, this method can improve inspection efficiency and reduce errors caused by manual inspection, thereby enhancing the reference value of tobacco quality judgment.

[0054] Understandably, see Figure 4 as well as Figure 6 As shown, the optical detector 130 detects distance by emitting light and measuring the time difference between the emitted and received light. Specifically, in this embodiment, the vertical height between the optical detector 130 and the bottom of the weighing chamber 1211 can be measured in advance, denoted as h0. The actual height between the optical detector 130 and the surface of the tobacco pile can then be determined through detection, denoted as h'. The result is h = h0 - h'.

[0055] Furthermore, in some embodiments, Figure 7 As shown, the height data includes the minimum height and maximum height of the tobacco pile. The first preset relationship includes a first sub-preset relationship, a second sub-preset relationship, and a third sub-preset relationship. The minimum height of the tobacco pile refers to the minimum height between the upper surface and the lower surface of the tobacco pile; the maximum height of the tobacco pile refers to the maximum height between the upper surface and the lower surface of the tobacco pile.

[0056] like Figure 7 As shown, the above step S200 also includes:

[0057] S210: Obtain the height difference between the highest altitude and the lowest altitude.

[0058] Here, let the highest height be h1 and the lowest height be h2. Let the height difference be △h, then △h=h1-h2.

[0059] S220: Acquire a preset relationship corresponding to the height difference.

[0060] When the height difference is less than or equal to the first value, the volume data is calculated according to the first sub-preset relationship.

[0061] That is, assuming the first value is X1, that is, when Δh≤X1, the volume data is calculated according to the first sub-preset relationship.

[0062] When the height difference is greater than the first value and less than or equal to the second value, the volume data is calculated according to the second sub-preset relationship.

[0063] That is, let the second value be X2. That is, when X1<Δh≤X2, the volume data is calculated according to the second sub-preset relationship.

[0064] When the height difference is greater than the second value, the volume data is calculated according to the third sub-preset relationship.

[0065] That is, when Δh>X2, the volume data is calculated according to the third sub-preset relationship.

[0066] For ease of understanding, the specific execution process of step S200 is described in detail below with reference to some example scenarios.

[0067] like Figure 4 As shown, when the height difference is less than or equal to a first value (e.g., equal to 0), that is, when Δh ≤ X1, the shape of the tobacco pile can be considered to be similar to a rectangular parallelepiped. The first sub-preset relationship can be related to the calculated volume of the rectangular parallelepiped. For example, the first sub-preset relationship satisfies any of the following formula relationships:

[0068] .......(1);

[0069] .......(2);

[0070] .......(3); where h1≤h3≤h2. In one example, h3= .

[0071] b is the correction coefficient.

[0072] like Figure 5 As shown, when the height difference is greater than the first value and less than or equal to the second value, that is, X1<△h≤X2, the tobacco pile can be considered to be arranged in a combined graphic configuration formed by a rectangular parallelepiped and a pyramid. The second sub-preset relationship can be related to the calculated volume of the rectangular parallelepiped and the pyramid. For example, the second sub-preset relationship satisfies the following formula:

[0073] .......(4); where b is the correction coefficient.

[0074] like Figure 6As shown, when the height difference is greater than the second value, that is, Δh>X2, the tobacco pile can be considered to be arranged in a cone. The third sub-preset relationship can be related to the calculated volume of the cone. For example, the third sub-preset relationship satisfies the following formula:

[0075] .......(5); where b is the correction coefficient.

[0076] In a specific example, the bottom area data of the weighing cavity 1211 can be obtained from the storage library. Assuming that the bottom area is 100 cm 2 Based on the data from the optical detection unit 130, assuming h1 = 15 cm and h2 = 5 cm, the height difference △h is calculated as h1 - h2 = 15 cm - 5 cm = 10 cm.

[0077] Assume X1 = 5 cm, X2 = 10 cm, and b = 0. Since Δh = 10 cm = X2, the second sub-preset relationship is selected to calculate the volume data.

[0078] The second sub-preset relationship adopts the above formula (4), namely:

[0079] ≈ 833cm 3 .

[0080] Calculate the tobacco density based on the weight and volume data. Assuming the detected weight data is 500g, then =500 / 833 = 0.6g / cm 3 =600kg / m 3 .

[0081] In an example, assuming the preset density is less than 200~600kg / m 3 In one example, if the detected tobacco density is too high, it can be determined that the tobacco density is greater than or equal to the preset density, and the quality of the sample tobacco can be determined to be qualified.

[0082] In this way, by considering the lowest and highest heights of the tobacco pile, calculating the height difference, and selecting different preset relationships based on the height difference to calculate the volume, the actual volume of the tobacco pile can be more accurately reflected, thereby improving the accuracy of tobacco quality testing. Furthermore, multiple preset relationships can adapt to tobacco piles of different shapes, enriching the application scenarios of tobacco quality testing device 100 and simplifying the complex calculation process. It eliminates the need to use calculus and other methods to determine the actual shape of the tobacco pile, thereby improving calculation efficiency.

[0083] In addition, in order to improve the detection accuracy of tobacco density, in some embodiments, Figure 8 As shown, the above step S100 specifically includes:

[0084] S110 , obtaining weight data of the tobacco pile in the weighing chamber 1211 .

[0085] S120 , obtaining the bottom area of ​​the weighing cavity 1211 .

[0086] S130: Obtain height data of the tobacco pile.

[0087] S131 : The optical detection component 130 obtains an actual detection distance value between the optical detection component 130 and the surface of the tobacco pile.

[0088] S132, the vertical height between the optical detection component 130 and the bottom of the cavity;

[0089] S133 , obtaining an angle between the light emitted by the optical detection component 130 and a direction perpendicular to the direction of gravity.

[0090] S134. Calculate and obtain height data corresponding to the actual detected distance value, vertical height value, and angle according to the third preset relationship.

[0091] For ease of understanding, the following is combined with an embodiment, such as Figure 9 As shown, the above step S130 is described in detail with an example.

[0092] Assuming that the actual detection distance is h3, the vertical height between the optical detection element 130 and the bottom of the cavity is h0, the included angle is θ, and the height data is h.

[0093] In one embodiment, Taking θ=30°, h0=30cm, h3=24cm as an example, then cm.

[0094] Generally, the installation angle of the optical detection component 130 may vary depending on the equipment installation location and environment. In this embodiment, by measuring and calculating the angle, it can adapt to different detection environments, improve detection accuracy, and enrich the application scenarios of the tobacco quality detection equipment 100.

[0095] In some embodiments, such as Figure 1 、 Figure 10 as well as Figure 11 As shown, the tobacco quality inspection device 100 further includes a gripping assembly 150, a release assembly 160, and a moving assembly 170. The gripping assembly 150 and the moving assembly 170 are mounted on the carrier assembly 110. The carrier 200 to be inspected is provided with a locking portion 200a. The gripping assembly 150 is provided with a locking engagement portion 150a. When the locking portion 200a and the locking engagement portion 150a are connected, the gripping assembly 150 grips and engages with the carrier 200 to be inspected, which is loaded with tobacco.

[0096] The moving assembly 170 is in driving connection with the grabbing assembly 150 to drive the grabbing assembly 150 to translate in a direction away from or toward the weighing carrier 121, so that the grabbing assembly 150 can drive the locking portion 200a and the locking mating portion 150a to be detachably connected. The carrier 200 to be tested is provided with a carrying cavity 210 and an opening 220, which is connected to the carrying cavity 210. The releasing assembly 160 is driven and engaged with the carrier 200 to drive the carrying cavity 210 to pour out the tobacco through the opening 220, so that the tobacco in the carrying cavity 210 can be transferred to the weighing cavity 1211.

[0097] In one example, see you later Figure 2 The control component 140 is in communication with the release component 160 and the moving component 170 , and the control component 140 is also used to drive the release component 160 and the moving component 170 .

[0098] Specifically, the method for using the tobacco quality inspection device 100 in the above embodiment is as follows: the moving assembly 170 is driven, so that the moving assembly 170 drives the grabbing assembly 150 to move in a direction away from the weighing carrier 121. At this time, the moving assembly 170 can drive the grabbing assembly 150 in a direction close to the carrier 200 to be inspected, thereby enabling the grabbing assembly 150 to reach the position of the carrier 200 to be inspected. Subsequently, the locking portion 200a of the grabbing assembly 150 can be connected to the locking mating portion 150a, and the moving assembly 170 is driven again, so that the moving assembly 170 drives the grabbing assembly 150 in a direction close to the weighing carrier 121.

[0099] When the grasping component 150 drives the carrier 200 to be detected to move to the position of the weighing carrier 121, the release component 160 is driven to allow the carrying cavity 210 to pour out the tobacco through the opening 220, and then the tobacco in the carrying cavity 210 can be transferred to the weighing cavity 1211.

[0100] In this way, through the cooperation of the moving component 170, the grabbing component 150 and the releasing component 160, the tobacco in the carrying cavity 210 can be transferred to the weighing cavity 1211, realizing the tobacco taking and placing process without manual delivery, thereby improving the convenience of using the tobacco quality detection equipment 100.

[0101] It should be noted that the grabbing assembly 150 in the above embodiment can be a combination of a motor and a hook, or a combination of a cylinder and a clamp, etc., and no further limitations are given here.

[0102] In one embodiment, see Figure 10The grabbing assembly 150 includes a first power source 151, a transmission assembly 152, and a grabbing arm 153. The first power source 151 is in transmission connection with the transmission assembly 152, so that the first power source 151 can drive the transmission assembly 152 to extend and retract along the height direction Z. The grabbing arm 153 is connected to the transmission assembly 152. A locking engagement portion 150a is provided on the grabbing arm 153.

[0103] The transmission assembly 152 can convert the motion vector along the height direction Z into the motion vector along the first direction X, so that the transmission assembly 152 can drive the grab arm 153 to extend and retract along the first direction X, so that the locking fitting portion 150a moves in a direction close to or away from the locking portion 20a. Figure 2 The control component 140 is in communication connection with the first power source 151 , and the control component 140 is used to drive the first power source 151 .

[0104] It is understood that the specific implementation process of the grasping assembly 150 can be as follows: when the first power source 151 drives the grasping arm 153 to extend and retract along the height direction Z through the transmission assembly 152, the locking portion 200a can be brought closer to the locking mating portion 150a. At the same time, the transmission assembly 152 can convert the motion vector along the height direction Z into a motion vector along the first direction X, so that the grasping arm 153 can swing in the direction close to the locking portion 200a along the first direction X, so that the locking mating portion 150a is separated from the locking portion 200a, and there is no movement obstruction between the locking mating portion 150a and the locking portion 200a. After the locking mating portion 150a is aligned with the locking mating portion 150a, the grasping assembly 150 can continue to be driven, so that the grasping arm 153 drives the locking mating portion 150a to swing in the direction close to the locking portion 200a, thereby connecting the locking mating portion 150a with the locking portion 200a, and realizing the grasping assembly 150 to grasp the carrier 200 to be detected.

[0105] In this way, the first power source 151 cooperates with the transmission of the grabbing arm 153 through the transmission component 152, so that the grabbing arm 153 has a motion vector in the height direction Z and the first direction X. This is different from the need to set up multiple power sources to separately control the movement of the grabbing arm 153 in different directions. This embodiment is beneficial to reducing the setting of driving components, thereby reducing costs and is beneficial to the miniaturization of the tobacco quality detection equipment 100.

[0106] Furthermore, the transmission assembly 152 enables the grabbing arm 153 to have a motion vector in both the first direction X and the height direction Z, so that the grabbing arm 153 can be more accurately aligned with the locking portion 200a of the carrier to be detected 200, thereby improving the alignment accuracy of the grabbing and reducing the risk of grabbing failure or damage to the carrier to be detected 200 due to position deviation.

[0107] It should be noted that the transmission assembly 152 in the above embodiment can be, but is not limited to, a connecting rod assembly, a matching assembly of a gear and a rack, etc., and no excessive restrictions are imposed here.

[0108] In one embodiment, see Figure 10 The transmission assembly 152 includes a first transmission member 1521 and a second transmission member 1522. One end of the first transmission member 1521 is in transmission connection with the first power source 151. The other end of the first transmission member 1521 is provided with a sliding portion 1521a on one end of the grabbing arm 153, and a sliding engagement portion 1531 on the other end. The second transmission member 1522 is connected to the supporting assembly 110. The grabbing arm 153 is rotatably mounted on the second transmission member 1522.

[0109] At least a portion of the sliding portion 1521a or at least a portion of the sliding fitting portion 1531 is tilted relative to the height direction Z. Assuming that the direction in which the first power source 151 drives the grab arm 153 to descend through the transmission assembly 152 is the first direction X, at least a portion of the sliding portion 1521a or at least a portion of the sliding fitting portion 1531 is tilted relative to the height direction Z means that: in one example, when the grab assembly 150 is assembled to the carrier assembly 110 and is engaged with the carrier 200 to be inspected, at least a portion of the sliding portion 1521a or at least a portion of the sliding fitting portion 1531 is tilted and extends gradually away from the locking portion 200a along the first direction X. In another example, when the grab assembly 150 is assembled to the carrier assembly 110 and is engaged with the carrier 200 to be inspected, at least a portion of the sliding portion 1521a or at least a portion of the sliding fitting portion 1531 is tilted and extends gradually toward the locking portion 200a along the first direction X.

[0110] When the first power source 151 drives the first transmission member 1521 to telescopically move along the height direction Z, the sliding portion 1521 a and the sliding fitting portion 1531 are limitedly slidingly fitted.

[0111] It can be understood that the grabbing arm 153 can be rotatably set on the second transmission member 1522, and when the sliding part 1521a slides with the sliding fitting part 1531, since the sliding part 1521a or the sliding fitting part 1531 is tilted relative to the height direction Z, the side wall of the sliding part 1521a will have an oblique upward or oblique downward pressure on the side wall of the sliding fitting part 1531, and then the first transmission member 1521 will press the grabbing arm 153 to rotate relative to the second transmission member 1522, so that the grabbing arm 153 can drive the locking fitting part 150a to rotate in a direction away from the locking part 200a or close to the locking part 200a, thereby achieving accurate alignment of the locking part 200a and the locking fitting part 150a.

[0112] In this way, different from the setting of the transmission component 152 such as the four-bar assembly, in this embodiment, through the sliding cooperation between the sliding part 1521a and the sliding cooperation part 1531, and the grabbing arm 153 can be rotatably set on the second transmission member 1522, the conversion of the motion vector in the height direction Z and the motion vector in the first direction X can be completed. The structure is relatively simple, easy to set up, and has high transmission accuracy, which is beneficial to improving the alignment accuracy of the locking part 200a and the locking cooperation part 150a.

[0113] Further, in some embodiments, Figure 10 The sliding fitting portion 1531 includes a first guide portion 1531a and a second guide portion 1531b. The first guide portion 1531a and the second guide portion 1531b are sequentially arranged and connected along the height direction Z, and the distance between the first guide portion 1531a and the second transmission member 1522 is smaller than the distance between the second guide portion 1531b and the second transmission member 1522.

[0114] When the sliding portion 1521a slidably engages with the first guide portion 1531a, the locking portion 200a and the locking engagement portion 150a are spaced apart. When the sliding portion 1521a slidably engages with the second guide portion 1531b, the locking portion 200a and the locking engagement portion 150a are connected. When the gripping assembly 150 is assembled to grip and engage with the carrier 200 to be inspected, the first guide portion 1531a is tilted away from the locking portion 200a. The second guide portion 1531b is tilted toward the locking portion 200a.

[0115] For ease of understanding, the two side walls of the sliding fitting portion 1531 opposite to each other along the first direction X are defined as a first side wall and a second side wall, respectively. The first side wall is located close to the locking portion 200a, and the second side wall is located away from the locking portion 200a.

[0116] It can be understood that the first guide portion 1531a is tilted in the direction away from the locking portion 200a. When the sliding portion 1521a moves downward in the height direction Z and the sliding portion 1521a is guided and matched with the first guide portion 1531a, an oblique downward abutment pressure is generated on the first side wall of the first guide portion 1531a, thereby causing the grabbing arm 153 to generate an oblique upward reaction force at the end away from the second transmission member 1522, and then causing the grabbing arm 153 to drive the locking matching portion 150a to rotate in the direction away from the locking portion 200a, which facilitates the alignment or disassembly process of the locking portion 200a and the locking matching portion 150a.

[0117] The second guide portion 1531b is tilted in the direction close to the locking portion 200a. When the sliding portion 1521a moves downward in the height direction Z and the sliding portion 1521a is guided and matched with the second guide portion 1531b, an oblique downward abutment pressure is generated on the second side wall of the second guide portion 1531b, thereby causing the grabbing arm 153 to generate an oblique upward reaction force at the end away from the second transmission member 1522, and then causing the grabbing arm 153 to drive the locking matching portion 150a to rotate in the direction close to the locking portion 200a, which facilitates the connection between the locking portion 200a and the locking matching portion 150a.

[0118] In this way, by setting the first guide part 1531a and the second guide part 1531b, the expansion and folding process of the grabbing arm 153 along the first direction X can be completed in the same lifting process, which is beneficial to improving the efficiency of precise alignment of the locking part 200a and the locking matching part 150a.

[0119] It should be noted that the driving cooperation between the release assembly 160 and the carrier to be detected 200 in the above embodiment can be, but is not limited to, the push rod 162 assembly used to cooperate with the carrier to be detected 200 to lift up, so that the carrier to be detected 200 can be rotated and reversed, and the tobacco in the carrying cavity 210 is guided out of the weighing cavity 1211. It can also be through the cooperation between the push rod 162 assembly and some switch modules.

[0120] In combination with any of the above embodiments of the release assembly 160, Figure 10 as well as Figure 12 As shown, the carrier 200 to be inspected is further provided with a switch 230. An opening 220 is provided at the bottom of the carrier 200 to be inspected. The switch 230 covers the opening 220. The switch 230 has an open state in which the switch 230 does not close the opening 220, and a closed state in which the switch 230 closes the opening 220.

[0121] The release assembly 160 includes a second power source, a third transmission member 161, and a push rod 162. The second power source is in transmission connection with the third transmission member 161, driving the third transmission member 161 to extend and retract along the height direction Z. The push rod 162 is connected to the third transmission member 161, enabling the third transmission member 161 to drive the push rod 162 to extend and retract along the height direction Z. When the push rod 162 abuts the switch member 230, the switch member 230 is in the open state. When the push rod 162 is spaced apart from the switch member 230, the switch member 230 is in the closed state.

[0122] In this way, the second power source drives the third transmission member 161 to extend and retract along the height direction Z. When the third transmission member 161 drives the push rod 162 to abut against the switch member 230, the switch member 230 is in an open state, and the tobacco can be poured out through the opening 220. Correspondingly, when the third transmission member 161 drives the push rod 162 to separate from the switch member 230, the switch member 230 is in a closed state, and the tobacco cannot be poured out through the opening 220, thereby ensuring stable storage of the tobacco within the carrier 200 to be detected.

[0123] Furthermore, unlike the method of switching the switch member 230 between the open state and the closed state by means of an electric switch such as a potential switch, in this embodiment, the switch member 230 can be switched between the open state and the closed state by driving the top rod 162 only by the second power source and the third transmission member 161, which is lower in cost and helps to reduce the processing cost of the tobacco quality detection equipment 100.

[0124] In one embodiment, if Figure 12 As shown, the switch member 230 is an elastic door member, which is rotatably arranged on the carrier 200 to be detected. The push rod 162 cooperates with the elastic door member to lift the elastic door member, so that the elastic door member overcomes the elastic force and opens, so that the carrying cavity 210 pours out the tobacco through the opening 220.

[0125] The locking portion 200a and the locking fitting portion 150a in the above embodiment may be, but are not limited to, snap-fit ​​connections, or may be magnetic connections or the like.

[0126] In some embodiments, see Figure 11 The locking portion 200a is a socket, and the locking mating portion 150a is a rod. The rod engages with the socket. In addition, the number of the grabbing arms 153 in the above embodiment can be one or more, such as two or three.

[0127] In some embodiments, see Figure 10 The transmission assembly 152 includes two grabbing arms 153 spaced apart from each other. Both grabbing arms 153 are rotatably mounted on the second transmission member 1522. The first transmission member 1521 includes a first connecting member 1521b and a second connecting member 1521c. One end of the first connecting member 1521b is in transmission connection with the first power source 151, and the first connecting member 1521b is connected to the second connecting member 1521c. The second connecting member 1521c is provided with sliding portions 1521a or sliding engagement portions 1531 on both sides along its length, so that the two sides of the second connecting member 1521c along its length can respectively slide and engage with the two grabbing arms 153.

[0128] In this way, the number of the grab arms 153 can be increased, thereby improving the stability of the grab arms 153 in the grabbing and cooperating process of the carrier 200 to be inspected, thereby avoiding the carrier 200 to be inspected from slipping or failing to be grabbed.

[0129] In some embodiments, see Figure 1 The tobacco quality inspection device 100 further includes a roller assembly 180 , which is installed at the bottom of the supporting assembly 110 to drive the supporting assembly 110 to roll.

[0130] In this way, the setting of the roller assembly 180 enables the carrying assembly 110 to be flexibly moved according to different carriers 200 to be detected or different positions on the production line, facilitating the use of the tobacco quality detection device 100 in different scenarios.

[0131] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
