Abstract
Description
Technical Field
[0001] The present application relates to the technical field of thickness detection, and in particular to a thickness detection device and a production system. Background Art
[0002] Heat-not-burn tobacco products are a new type of tobacco product. Since the core material in heat-not-burn tobacco products does not participate in combustion, the large amount of harmful substances produced by high-temperature combustion and decomposition are reduced, thereby reducing harm to the human body and reducing pollution to the environment.
[0003] There are two main methods for online thickness detection of cigarette core materials in related technologies, one is contact type and the other is non-contact type. The contact type usually uses a probe to press against the cigarette core material and exert a certain pressure on the cigarette core material to detect the thickness of the cigarette core material online under the premise of meeting the thickness measurement pressure; however, the probe is prone to wear after working for a long time and requires regular maintenance, which affects production efficiency and increases production costs. The non-contact type usually uses a laser ranging probe to scan the cigarette core material in opposite directions; however, the non-contact type cannot meet the pressure standard for thickness detection, resulting in low accuracy of the measurement results.

[0036] Embodiment 1
[0037] See also Figures 1 to 3 This embodiment provides a thickness detection device 100. The thickness detection device 100 is used to detect the thickness of a workpiece 200 online.
[0038] The test piece 200 in this embodiment may be a tobacco core material in a heat-not-burn tobacco product.
[0039] See also Figure 1 , define the height direction of the thickness detection device 100 as the first direction X; and the length direction of the thickness detection device 100 as the second direction Y.
[0040] The first direction X is perpendicular to the second direction Y. It is understandable that the above definition is only for facilitating the understanding of the relative position relationship of the various parts in the thickness detection device 100 and should not be construed as a limitation to the present application.
[0041] See also Figure 1 The thickness detection device 100 mainly includes a frame 110 , a transmission module 120 and a measurement module 130 .
[0042] The frame body 110 includes a first bracket 111 , a second bracket 112 , and a third bracket 113 arranged side by side along the second direction Y, and the second bracket 112 and the third bracket 113 are symmetrically arranged with the first bracket 111 as the center.
[0043] The transmission module 120 includes a first rotating member 121, a second rotating member 122, and a third rotating member 123. The first rotating member 121 is rotatably disposed on the first bracket 111, the second rotating member 122 is rotatably disposed on the second bracket 112, and the third rotating member 123 is rotatably disposed on the third bracket 113. The second rotating member 122 and the third rotating member 123 are symmetrically disposed with the first rotating member 121 as the center, and the first rotating member 121, the second rotating member 122, and the third rotating member 123 are not disposed in a colinear manner.
[0044] The test piece 200 is simultaneously wound around the first rotating member 121, the second rotating member 122, and the third rotating member 123. Under the joint action of the first rotating member 121, the second rotating member 122, and the third rotating member 123, the test piece 200 can be driven, so that the thickness detection device 100 can detect the thickness of the test piece 200 while the test piece 200 keeps moving.
[0045] The second rotating member 122 and the third rotating member 123 have a rotation speed difference, so that the test piece 200 has a certain tension. The tension of the test piece 200 can make the test piece 200 press the first rotating member 121 along the first direction X, thereby ensuring that the test piece 200 meets the thickness measurement pressure standard.
[0046] The measuring module 130 is disposed on the first bracket 111 ; the probe of the measuring module 130 is directed toward the first rotating member 121 in the first direction X.
[0047] The probe of the measuring module 130 can measure the distance from the workpiece 200 on the first rotating member 121 to the probe, and then obtain the thickness of the workpiece 200 on the first rotating member 121 through calculation.
[0048] The thickness of the object to be tested 200 is the distance from the probe to the first rotating member 121 minus the distance from the probe to the object to be tested 200 on the first rotating member 121 .
[0049] The thickness detection device 100 of this embodiment can measure the thickness of the test piece 200 online under the condition of meeting the thickness detection pressure standard. Since there is a certain distance between the probe of the measuring module 130 and the test piece 200, wear between the probe of the measuring module 130 and the test piece 200 is effectively avoided.
[0050] Exemplarily, the first rotating member 121, the second rotating member 122 and the third rotating member 123 are all rotating rollers, and the axial direction of the first rotating member 121 is perpendicular to the first bracket 111, the axial direction of the second rotating member 122 is perpendicular to the second bracket 112, and the axial direction of the third rotating member 123 is perpendicular to the third bracket 113.
[0051] In some embodiments, see Figure 1 The frame body 110 further includes a base 114 ; the first bracket 111 is fixed on the base 114 , and the second bracket 112 and the third bracket 113 are respectively slidably matched with the base 114 .
[0052] The second bracket 112 and the third bracket 113 can move on the base 114 in opposite directions or in opposite directions along the second direction Y, thereby changing the contact area between the test piece 200 and the first rotating member 121 and changing the pressure of the test piece 200 pressing the first rotating member 121 along the first direction X to meet different thickness detection pressure standards.
[0053] Exemplarily, the base 114 is provided with a slide rail extending along the second direction Y; one end of the first bracket 111 along the first direction X is fixed to the base 114; the second bracket 112 and the third bracket 113 are respectively slidably matched with the slide rail through corresponding sliders, so that the second bracket 112 and the third bracket 113 move along the second direction Y on the base 114.
[0054] See also Figure 1 and Figure 2 , since the second bracket 112 and the third bracket 113 are symmetrically arranged with the first bracket 111 as the center; when the second bracket 112 and the third bracket 113 move toward each other along the second direction Y, the distance between the second rotating member 122 and the third rotating member 123 decreases, so that the contact area between the test piece 200 and the first rotating member 121 increases. When the second bracket 112 and the third bracket 113 move away from each other along the second direction Y, the distance between the second rotating member 122 and the third rotating member 123 increases, so that the contact area between the test piece 200 and the first rotating member 121 decreases.
[0055] The contact area between the test piece 200 and the first rotating piece 121 can be calculated by the following formula:
[0056]
[0057] Among them, S is the contact area between the test piece 200 and the first rotating member 121; r is the radius of the first rotating member 121; L is the width of the first rotating member 121; a is the angle between the test piece 200 and the horizontal plane at the point where the test piece 200 and the first rotating member 121 are tangent; b is the arc corresponding to the arc length of the area where the test piece 200 and the first rotating member 121 are connected.
[0058] It is worth noting that since the second rotating member 122 and the third rotating member 123 are symmetrically arranged with the first rotating member 121 as the center, and the first rotating member 121, the second rotating member 122 and the third rotating member 123 are not arranged in a colinear manner, 2a=b.
[0059] By moving the second bracket 112 and the third bracket 113 toward each other or away from each other, the values of a and b are changed, thereby adjusting the contact area S between the test piece 200 and the first rotating piece 121 .
[0060] The pressure of the test piece 200 on the first rotating piece 121 along the first direction X can be calculated by the following formula:
[0061] N=F×sin a
[0062] Wherein, N is the pressure of the test piece 200 on the first rotating member 121 along the first direction X; F is the tension of the test piece 200; a is the angle between the test piece 200 and the horizontal plane at the tangent point between the test piece 200 and the first rotating member 121.
[0063] The greater the speed difference between the first rotating member 121 and the second rotating member 122 , the greater the tension F of the test piece 200 .
[0064] When the tension F of the test piece 200 is constant, the larger the contact area between the test piece 200 and the first rotating member 121 is, the greater the pressure N of the test piece 200 on the first rotating member 121 along the first direction X is.
[0065] The relationship between the pressure P that the test piece 200 is required to withstand during measurement, the pressure N of the test piece 200 on the first rotating member 121 along the first direction X, and the contact area S between the test piece 200 and the first rotating member 121 is:
[0066]
[0067] It can be seen from the above relationship that by adjusting the speed difference between the second rotating member 122 and the third rotating member 123, or adjusting the distance between the first rotating member 121 and the second rotating member 122, the test piece 200 can meet the required pressure P standard when measuring the thickness online.
[0068] In some embodiments, the base 114 is provided with a slide rail extending along the second direction Y; one end of the first bracket 111 along the first direction X is fixed to the base 114; the second bracket 112 and the third bracket 113 are respectively slidably matched with the slide rail through corresponding sliders, so that the second bracket 112 and the third bracket 113 move along the second direction Y on the base 114.
[0069] In some embodiments, see Figure 1 The first rotating member 121 is arranged at one end of the first bracket 111 away from the base 114 along the first direction X; the height of the first rotating member 121 along the first direction X is higher than the heights of the second rotating member 122 and the third rotating member 123; the measuring module 130 is located on a side of the first rotating member 121 away from the base 114.
[0070] Further, the second rotating member 122 is slidably matched with the second bracket 112 along the first direction X, so that the second rotating member 122 can move on the second bracket 112 along the first direction X. The third rotating member 123 is slidably matched with the third bracket 113 along the first direction X, so that the third rotating member 123 can move on the third bracket 113 along the first direction X.
[0071] When the second rotating member 122 and the third rotating member 123 gradually approach the base 114 along the first direction X, the angle a between the tested member 200 and the horizontal plane at the tangent point of the tested member 200 and the first rotating member 121 gradually increases, thereby increasing the contact area S between the tested member 200 and the first rotating member 121.
[0072] When the second rotating member 122 and the third rotating member 123 gradually move away from the base 114 along the first direction X, the angle a between the tested member 200 and the horizontal plane at the tangent point of the tested member 200 and the first rotating member 121 gradually decreases, thereby reducing the contact area S between the tested member 200 and the first rotating member 121.
[0073] By changing the heights of the second rotating member 122 and the third rotating member 123 in the first direction X, the contact area S between the test object 200 and the first rotating member 121 can also be adjusted.
[0074] In another embodiment, see Figure 3 The first rotating member 121 is arranged at one end of the first bracket 111 close to the base 114 along the first direction X; the height of the first rotating member 121 along the first direction X is lower than the heights of the second rotating member 122 and the third rotating member 123; the measuring module 130 is located on one side of the first rotating member 121 close to the base 114.
[0075] When the second rotating member 122 and the third rotating member 123 gradually approach the base 114 along the first direction X, the contact area S between the test piece 200 and the first rotating member 121 decreases.
[0076] When the second rotating member 122 and the third rotating member 123 gradually move away from the base 114 along the first direction X, the contact area S between the test piece 200 and the first rotating member 121 increases.
[0077] In some embodiments, the thickness detection device 100 also includes a first driving member and a second driving member; the driving end of the first driving member is connected to the second rotating member 122; the driving end of the second driving member is connected to the third rotating member 123; by respectively adjusting the driving power of the first driving member and the driving power of the second driving member, the second rotating member 122 and the third rotating member 123 can rotate at different speeds, thereby making the test piece 200 have a certain tension.
[0078] Exemplarily, the first driving member and the second driving member are both variable frequency motors.
[0079] In some embodiments, the transmission module 120 further includes a fourth rotating member 124 and a fifth rotating member 125 ; the fourth rotating member 124 is rotatably disposed on the second bracket 112 , and the fifth rotating member 125 is rotatably disposed on the third bracket 113 .
[0080] In some embodiments, the test piece 200 is sequentially wound around the fourth rotating member 124 , the second rotating member 122 , the first rotating member 121 , the third rotating member 123 , and the fifth rotating member 125 .
[0081] The fourth rotating member 124 and the fifth rotating member 125 can change the moving direction of the test piece 200 and increase the tension of the test piece 200 to ensure the transmission stability of the test piece 200 .
[0082] In some embodiments, the fourth rotating member 124 slides with the second bracket 112 along the first direction X; the fifth rotating member 125 slides with the third bracket 113 along the first direction X to further adjust the tension of the test piece 200 .
[0083] The fourth rotating member 124 and the fifth rotating member 125 can be connected to corresponding driving members respectively to adjust the rotation speeds of the fourth rotating member 124 and the fifth rotating member 125 respectively.
[0084] In some embodiments, see Figure 1 and Figure 3 The first rotating member 121 and the measuring module 130 are respectively slidably matched with the first bracket 111 along the first direction X, so as to adjust the distance from the probe of the measuring module 130 to the first rotating member 121 along the first direction X.
[0085] Exemplarily, the measuring module 130 is a laser ranging module.
[0086] In some embodiments, a pressure sensor is disposed on the first rotating member 121 ; the pressure sensor is used to detect the pressure of the test piece 200 along the first direction X on the first rotating member 121 .
[0087] In some embodiments, the thickness detection device 100 further includes a controller, and the controller is electrically connected to the pressure sensor; the data detected by the pressure sensor can be transmitted to the controller via an electrical signal.
[0088] In some embodiments, the controller is also electrically connected to the stepper motor in the slide rail. The controller can adjust the positions of the second bracket 112 and the third bracket 113 along the second direction Y by calculation.
[0089] In some embodiments, the second rotating member 122 is rotationally connected to the second bracket 112 via a first worm gear; the third rotating member 123 is rotationally connected to the third bracket 113 via a second worm gear.
[0090] In some embodiments, the controller is also electrically connected to the first worm gear and the second worm gear, respectively. The controller can adjust the height of the second rotating member 122 and the third rotating member 123 along the first direction X by calculation.
