Description

Technical Field

[0001] The utility model relates to the technical field of tobacco detection equipment, in particular to a calibration device for a cigarette hardness detector and a cigarette hardness detection device. Background Art

[0002] The hardness of a cigarette is an important physical and technical index in the cigarette production process, which reflects the fullness and distribution of the tobacco filling in the cigarette, and is also related to other physical indexes of the cigarette, such as weight, draw resistance, etc., and affects people's smoking experience.

[0003] In the process of using a cigarette hardness detector to detect the hardness of a cigarette, the moving mechanism of the cigarette hardness detector moves up and down to drive the weight up and down, and a certain pressure is applied to the cigarette through the weight and the pressure head. The hardness of the cigarette is judged according to the deformation of the cigarette under pressure. Before the hardness detection, usually, the pressure head and the weight need to be removed, weighed with a balance and then reinstalled. The sum of the weighed weight of the weight and the weight of the pressure head is the applied pressure weight, and this applied pressure weight is used as the applied pressure parameter of the cigarette hardness detector.

[0004] However, in the actual hardness measurement process, there is a moving friction force between the weight and the moving mechanism, which may cause the actual pressure applied to the cigarette to be inconsistent with the weighed applied pressure weight, resulting in a low detection accuracy of the cigarette hardness.

All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present utility model belong to the scope of protection of the present utility model.

"Upper" and "lower". The terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific situations.

[0024] The following will describe Figure 1 and Figure 2 the cigarette rod hardness detector calibration device and the cigarette rod hardness detection device of the present utility model.

[0025] As Figure 1 and Figure 2 shown, the calibration device 100 for the cigarette rod hardness detector provided by the embodiment of the present utility model includes a mounting base 11 and a calibration main body 12. The calibration main body 12 is provided with a pressure-receiving part 123. The mounting base 11 is used to connect with the cigarette rod hardness detector 200, and the calibration main body 12 is mounted on the mounting base 11 so that the pressure-receiving part 123 is opposite to the pressing head 22 of the cigarette rod hardness detector 200. The calibration main body 12 is used to detect the load applied by the pressing head 22 to the pressure-receiving part 123.

[0026] Specifically, referring to Figure 2 , the cigarette rod hardness detector 200 includes a detection table 21, a pressing head 22 and a weight 23. The detection table 21 is provided with a mounting position 213 adapted to the sample to be measured. The pressing head 22 is arranged above the mounting position 213 in the vertical direction. The moving mechanism on the detection table 21 drives the pressing head 22 to move in the vertical direction. One end of the pressing head 22 faces the mounting position 213, and the other end of the pressing head 22 is connected to the weight 23. When using the cigarette rod hardness detector 200 to detect the hardness of the sample to be measured, the pressing head 22 is pressed on the sample to be measured, and the weight 23 and the pressing head 22 apply pressure to the sample to be measured as a whole.

[0027] The calibration device 100 for the cigarette rod hardness detector provided by the embodiment of the present utility model is used to calibrate the pressure application parameter of the cigarette rod hardness detector 200. During the calibration process, the pressure-receiving part 123 is arranged below the pressing head 22, and the situation of the sample to be measured being pressed is simulated by the pressure-receiving part 123. The pressure received by the pressure-receiving part 123 from the pressing head 22 is the pressure received by the sample to be measured during actual testing.

[0028] The calibration steps are as follows: Connect and fix the calibration device 100 for the cigarette rod hardness detector with the cigarette rod hardness detector 200 through the mounting base 11, and make the pressure-receiving part 123 opposite to the pressing head 22; the moving end of the moving mechanism moves downward so that the pressing head 22 and the weight 23 are pressed on the pressure-receiving part 123 as a whole. At this time, the total pressure applied by the pressing head 22 and the weight 23 to the pressure-receiving part 123 is detected by the calibration main body 12, that is, the pressure application value; record this pressure application value and input it as the pressure application parameter into the cigarette rod hardness detector to complete the calibration. When testing the sample to be measured subsequently, the hardness of the sample to be measured is evaluated with this pressure application parameter.

[0029] Among them, before calibrating the pressure application value, the weight 23 can be removed, and the moving end of the moving mechanism moves downward so that the single pressing head 22 is pressed on the pressure-receiving part 123. At this time, the pressure applied by the pressing head 22 to the pressure-receiving part 123 is detected by the calibration main body 12, that is, the pre-pressure value. So as to select a suitable pressing head 22 to pre-press the sample to be measured when testing samples to be measured with different specifications.

[0030] The calibration device 100 for the cigarette rod hardness detector provided by the embodiment of the utility model, by setting the mounting base 11 and the calibration main body 12, the calibration main body 12 is connected to the cigarette rod hardness detector 200 through the mounting base 11, so that the pressure receiving part 123 of the calibration main body 12 is opposite to the pressing head 22 of the cigarette rod hardness detector 200. The pressing head 22 applies pressure to the pressure receiving part 123 to simulate the pressure applied by the pressing head 22 to the sample to be tested during actual testing, and the calibration main body 12 detects this pressure and takes this pressure value as the pressure application parameter to realize the on-line calibration of the cigarette rod hardness detector 200, thereby avoiding the inconsistency between the pressure actually applied to the cigarette rod and the applied pressure weight obtained by weighing, and improving the detection accuracy of the cigarette rod hardness.

[0031] At present, cigarette rod hardness detectors that meet national standards are used for cigarette rod hardness detection. Relevant national standards stipulate that the diameter of the pressing head is 12 mm, and the test area is a rectangular plane of 20 mm × 20 mm. The bottom end of the pressing head 22 is only 12 mm away from the maximum distance of the test area, and the test space is very small, which is not convenient for the setting of the calibration device 100 for the cigarette rod hardness detector.

[0032] In this regard, the calibration main body 12 in the calibration device 100 for the cigarette rod hardness detector provided by the embodiment of the utility model includes a main body 121 and a weighing beam 122. As Figure 1 shown, the weighing beam 122 is connected to the main body 121 and extends in a direction away from the main body 121, and the pressure receiving part 123 is arranged at one end of the weighing beam 122 away from the main body 121.

[0033] Specifically, the weighing beam 122 is a slender structure relative to the main body 121, and one end of it away from the main body 121 can extend into the very small test space between the pressing head 22 and the test area, so that the pressure receiving part 123 is opposite to the pressing head 22, avoiding structural interference between the calibration device 100 for the cigarette rod hardness detector and the cigarette rod hardness detector 200.

[0034] It should be noted that, when the test space permits, the pressure receiving part 123 can be arranged on the main body 121 without setting the weighing beam 122.

[0035] Furthermore, a strain gauge (not shown in the figure) is arranged on the weighing beam 122 for detecting the deformation of the weighing beam 122, and the strain gauge is electrically connected to the main body 121.

[0036] Specifically, the strain gauge is arranged along the length direction of the weighing beam 122. When one end of the weighing beam 122 is subjected to the pressure of the pressing head 22, it will bend and deform, and the strain gauge will deform accordingly and convert this deformation into a corresponding electrical signal and input it into the main body 121. The main body 121 determines the pressure received by the pressure receiving part 123 according to this electrical signal.

[0037] In some alternative embodiments, the pressure applied to the pressure-receiving part 123 may not be sensed by the strain gauge on the weighing beam 122. For example, a pressure sensor may be provided on the pressure-receiving part 123, and the pressure sensor is electrically connected to the calibration body 12. The pressure applied to the pressure-receiving part 123 is sensed by the pressure sensor and output to the main body 121.

[0038] The cigarette rod hardness detector calibration device 100 provided by the embodiment of the present invention further includes a weighing piece 124. The weighing piece 124 is detachably arranged on the pressure-receiving part 123 and is used to contact the pressing head 22.

[0039] It can be understood that the weighing piece 124 is arranged on the pressure-receiving part 123 as a gasket to prevent the pressing head 22 from directly contacting the pressure-receiving part 123 and avoid wear of the pressure-receiving part 123 under the long-term action of the pressing head 22.

[0040] Among them, the weighing piece 124 is detachably connected to the weighing beam 122. For example, the weighing piece 124 and the weighing beam 122 are fixedly connected by bolts. Specifically, the weighing piece 124 is provided with a countersunk hole, and the weighing beam 122 is provided with a first mounting hole corresponding to the countersunk hole. The weighing piece 124 is connected to the weighing beam 122 by a screw passing through the countersunk hole and the first mounting hole. The head of the screw is not higher than the upper surface of the weighing piece 124 to ensure the flatness of the upper surface of the weighing piece 124.

[0041] Furthermore, the pressure-receiving part 123 is provided with a positioning groove 1231, and the weighing piece 124 is arranged in the positioning groove 1231. When installing the weighing piece 124, the weighing piece 124 can be first placed in the positioning groove 1231 for preliminary positioning, and then the weighing piece 124 is fixed. The external dimension of the positioning groove 1231 can be slightly larger than that of the weighing piece 124 and is adapted to the external shape of the weighing piece 124. For example, if the weighing piece 124 is set as a rectangular piece, the positioning groove 1231 is correspondingly set as a rectangular groove.

[0042] In an alternative embodiment, the weighing beam 122 is detachably connected to the main body 121. Specifically, the main body 121 includes a housing and a processing unit arranged in the housing, and the weighing beam 122 is detachably connected to the housing.

[0043] The cigarette rod hardness detector calibration device 100 is usually installed on the edge of the detection table 21 of the cigarette rod hardness detector 200. The distances between the installation positions 213 on different models of cigarette rod hardness detectors 200 and the edge of the detection table 21 are different. In this embodiment, by detachably connecting the weighing beam 122 to the main body 121, the replacement of the weighing beam 122 can be realized. Different lengths of weighing beams 122 are combined with the main body 121 to adapt to different models of cigarette rod hardness detectors 200, improving the versatility of the cigarette rod hardness detector calibration device 100.

[0044] The main body 121 in the cigarette hardness tester calibration device 100 provided in the embodiment of the utility model includes a processing unit and a display unit 1211. The processing unit is used to determine the load applied by the pressure head 22 to the pressure receiving part 123. The processing unit and the display unit 1211 are in communication connection.

[0045] Specifically, the processing unit is electrically connected to the strain gauge or pressure sensor described in the above embodiment, and determines the load on the pressure-bearing part 123 according to the received electrical signal. The display unit 1211 is used to display the load value for the operator to observe and record.

[0046] The main body 121 further includes a battery 1212, and the processing unit and the display unit 1211 are electrically connected to the battery 1212 respectively. The battery 1212 may be a storage battery or a dry cell. It should be noted that the cigarette hardness tester calibration device 100 may also be provided with a power connector, which is connected to an external power source through the power connector. Of course, the battery 1212 or the power connector may be provided separately, or the battery 1212 and the power connector may be provided simultaneously.

[0047] Furthermore, the battery installation slot of the body 121 is arranged on a side thereof facing away from the mounting seat 11 , that is, usually on an upward side of the body 121 , so as to facilitate installation and removal of the battery 1212 .

[0048] In some embodiments of the utility model, the mounting base 11 is provided with a second mounting hole 112, and the cigarette hardness tester 200 is provided with a reserved hole corresponding to the second mounting hole 112. The mounting base 11 is detachably connected to the cigarette hardness tester 200 by means of fixing parts such as bolts passing through the second mounting hole 112 and the reserved hole, so as to facilitate the assembly and disassembly of the calibration device before and after the calibration work.

[0049] In some embodiments of the utility model, the verification body 12 is detachably connected to the mounting seat 11, specifically, the body 121 is detachably connected to the mounting seat 11, which can facilitate the maintenance of the verification body 12, and the verification body 12 can be configured with mounting seats 11 of different structural shapes to adapt to different models of cigarette hardness testers 200, thereby improving the versatility of the cigarette hardness tester verification device 100. Optionally, the verification body 12 is connected to the mounting seat 11 by bolts.

[0050] In some embodiments of the present invention, the mounting seat 11 is provided with a limiting portion 111 , and at least one side of the verification body 12 is in limiting cooperation with the limiting portion 111 .

[0051] Specifically, a counterbore is provided on the mounting base 11, and the calibration main body 12 is arranged on the counterbore. The counterbore has at least one side surface, and at least one side surface serves as a limiting portion 111 to be in limiting cooperation with the calibration main body 12. When installing the calibration main body 12 and the mounting base 11, the installation position of the main body 121 is defined by the side surface of the counterbore, that is, at least one side of the main body 121 abuts against the corresponding side surface of the counterbore, and then the main body 121 is fixedly connected to the mounting base 11. As Figure 1 shown, the counterbore has one side surface, and one side of the main body 121 abuts against this side surface.

[0052] It should be noted that the limiting portion 111 is not limited to the counterbore design. For example, it can also be a strip-shaped protrusion protruding from the mounting base 11.

[0053] The embodiment of the present utility model also provides a cigarette rod hardness detection device. As Figure 2 shown, the cigarette rod hardness detection device includes a cigarette rod hardness detector 200 and the cigarette rod hardness detector calibration device 100 described in any one of the above embodiments. Among them, the cigarette rod hardness detector 200 includes a base 211, a sample table 212 and a pressing head 22. The sample table 212 is movably arranged on the base 211. The sample table 212 is provided with a mounting position 213 adapted to the sample to be measured. The mounting base 11 is detachably connected to the base 211. In the vertical direction, the pressing head 22 is located above the pressed portion 123, and the pressed portion 123 is located above the mounting position 213.

[0054] Among them, the detection table 21 described in the above embodiment includes a base 211 and a sample table 212. A motion mechanism is installed on the base 211. The moving end of the motion mechanism is movable relative to the base 211 in the vertical direction, so that the pressing head 22 and the weight 23 arranged thereon move up and down. When the pressing head 22 presses on the pressed portion 123, the weight 23 and the pressing head 22 as a whole apply pressure to the pressed portion 123.

[0055] The cigarette rod hardness detector 200 further includes a driving mechanism. The driving mechanism is connected to the sample table 212 and is used to drive the sample table 212 to move along the axis direction of the sample to be measured, and cooperate with the up and down movement of the moving end of the motion mechanism to realize the continuous detection of multiple samples to be measured.

[0056] Further, the cigarette rod hardness detector 200 further includes a weight 23. One end of the pressing head 22 faces the pressed portion 123, and the other end of the pressing head 22 is connected to the weight 23. The moving end of the motion mechanism is connected with a bushing 24, and the bushing 24 is sleeved on the pressing head 22. After the moving end of the motion mechanism moves downward to make the pressing head 22 contact the pressed portion 123 or the sample to be measured, when the moving end of the motion mechanism continues to move downward, the pressing head 22 and the weight 23 as a whole can be pressed on the pressed portion 123 or the sample to be measured.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
