Description

Technical Field

[0001] The utility model relates to a device for measuring the hardness of cigarette samples. Background Technique

[0002] Cigarette hardness is an important physical index of cigarettes. If the cigarette hardness is too low, problems such as damage to the appearance during cigarette transportation and the dropping of the combustion cone during consumer smoking may occur. If the cigarette hardness is too high, problems such as an increase in cigarette draw resistance, an increase in the content of smoke components, and an increase in tobacco consumption may occur. Therefore, appropriate cigarette hardness is very important for both the appearance and sensory experience of cigarettes. In addition, cigarette hardness directly reflects the tobacco content of the cigarette stick, so cigarette hardness is also an important reference index for formulating cigarette weight standards.

[0003] In the prior art, Chinese Patent Application CN202022229507.8 discloses a cylindrical sample hardness detection unit, including a frame and a hardness detection device installed on the frame, and further including a sample feeding device. The sample feeding device includes a first sample guiding device, a second sample guiding device, and a sample pushing device. The first and second sample guiding devices and the sample pushing device are all installed on the frame. The first sample guiding device is located above the second sample guiding device, and the sample pushing device is located to the right of the second sample guiding device. A gap is formed between the first sample guiding device and the second sample guiding device. After passing through the first sample guiding device, the sample can enter the second sample guiding device. The sample pushing device can move in the gap and can push the sample located in the second sample guiding device to the hardness detection device for detection.

[0004] In the above prior art, only the same position of the sample can be detected. If other positions need to be detected, manual adjustment is required, which is very inconvenient. Content of the Utility Model

[0005] In view of this, the utility model provides a multi-point hardness measurement device, which can realize the multi-point hardness detection of cigarette samples.

[0006] To solve the above technical problems, the technical solution of the utility model is to adopt a multi-point hardness measurement device, including a detection module for detecting the hardness of cigarette samples and a material conveying module for conveying cigarette samples;

[0007] The material conveying module includes a receiving cylinder, which can rotate from the receiving position to the detection position, so that the cigarette samples loaded into the receiving cylinder rotate from the receiving position to the detection position; it also includes a pushing mechanism for pushing the cigarette samples in the receiving cylinder towards the detection module. The pushing mechanism includes a pushing rod, and the pushing rod can move axially along the receiving cylinder when it is in the detection position, so as to push the cigarette samples in the receiving cylinder axially along the receiving cylinder when it is in the detection position; the distance that the pushing rod moves axially along the receiving cylinder when it is in the detection position can be adjusted, so as to adjust the position of the cigarette samples entering the detection module.

[0008] As an improvement, it further includes a slide rail arranged axially parallel to the receiving cylinder at the detection position. A slider that can move along the slide rail is arranged on the slide rail; the pushing rod is arranged on the slider.

[0009] As a further improvement, the bottom and side walls of the receiving cylinder are provided with sliding grooves. One end of the pushing rod is connected to the slider, and the other end extends into the receiving cylinder.

[0010] As another even further improvement, it further includes a scale arranged axially along the slide rail.

[0011] As an improvement, the detection module includes a weight assembly for pressing on the sample branch and a distance detection device for measuring the distance of compression of the sample branch by the weight assembly.

[0012] As an improvement, the detection position of the sample branch is horizontal, and the pressing direction of the weight assembly is vertical; the weight assembly includes a weight body and a driving mechanism for driving the weight body to move vertically; the weight body includes a loading weight and a preloading weight. The loading weight is slidably connected to the driving mechanism by a sleeve, so that the loading weight can float up and down; the preloading weight includes a core rod and a pressing head. The core rod penetrates the sleeve and can slide axially along the sleeve; the pressing head is connected to the lower end of the core rod and extends out of the sleeve; the preloading weight can float up and down, and when the preloading weight floats up, the pressing head can abut against the lower end of the sleeve.

[0013] As an improvement, both ends of the sleeve are tapered sleeves.

[0014] As an improvement, an air bearing is arranged between the sleeve and the driving mechanism.

[0015] As an improvement, the detection module further includes a load platform for carrying the sample branch for hardness detection, and the load platform is located below the weight assembly.

[0016] As an improvement, the distance detection device is a laser ranging probe located above the weight mechanism, and the laser ranging probe detects the compression amount of the sample branch by detecting the displacement of the core rod.

[0017] The beneficial effects of the present utility model are as follows:

[0018] The present utility model pushes the sample branch to the detection module through the pushing rod, and the pushing distance can be adjusted. Therefore, each part of the sample branch can be pushed to the detection module, so as to realize the hardness detection at multiple points. The present utility model does not require manual adjustment of the position of the sample branch. By presetting the detection points, the hardness of multiple positions of the sample branch can be detected at one time, greatly improving the detection efficiency and reducing the labor intensity of the operator.

Detailed implementation manners

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the specific implementation manners.

[0026] As Figure 1 shown, the present utility model provides a multi-point hardness measurement device, including a detection module for hardness detection of the sample 100 and a material transfer module for transferring the sample;

[0027] The material transfer module includes a material receiving cylinder 34, and the material receiving cylinder 34 can rotate from the material receiving position to the detection position, so that the sample 100 loaded into the material receiving cylinder 34 rotates from the material receiving position to the detection position; it also includes a pushing mechanism for pushing the sample 100 in the material receiving cylinder 34 towards the detection module. The pushing mechanism includes a pusher rod 310, and the pusher rod 310 can move axially along the material receiving cylinder 34 when it is in the detection position, so as to push the sample 100 in the material receiving cylinder 34 axially along the detection position of the material receiving cylinder 34; the distance that the pusher rod 310 moves axially along the detection position of the material receiving cylinder 34 can be adjusted, so as to adjust the position of the sample entering the detection module.

[0028] The utility model pushes the sample to the detection module through the pushing rod 310, and the pushing distance can be adjusted. Therefore, each part of the sample can be pushed to the detection module, so as to realize the hardness detection at multiple points. The utility model does not require manual adjustment of the position of the sample. By presetting the detection points, the hardness of multiple positions of the sample can be detected at one time, greatly improving the detection efficiency and reducing the labor intensity of the operator.

[0029] Specifically, as Figure 2 、 Figure 3 shown, in this embodiment, there is also a slide rail 35 arranged parallel to the axial direction of the receiving cylinder 34 at the detection position. A slider 37 that can move along the slide rail 35 is arranged on the slide rail 35; the pushing rod 310 is arranged on the slider 37. The slider 37 is driven by a linear driving mechanism 39. The cooperation of the slide rail 35 and the slider 37 is used to drive the pushing rod 310, so that the action of the pushing rod 310 is more accurate and convenient to control. Of course, other devices can also be used to drive the pushing rod 310, such as an electric push rod, etc., and the utility model does not make any restrictions.

[0030] As Figure 4 shown, for the convenience of arrangement, in this embodiment, the bottom and side walls of the receiving cylinder 34 are provided with chutes. Of course, in order to prevent the sample 100 from slipping from the bottom, the width of the chute should be smaller than that of the sample. One end of the pushing rod 310 is connected to the slider 37, and the other end extends into the receiving cylinder 34. It can be foreseen that the pushing rod 310 is relatively flat and can extend into the chute. Of course, the position where the pushing rod 310 contacts the sample 100 can be relatively wide, so as to increase the contact area and avoid unbalanced force.

[0031] In some embodiments, there is also a scale 36 arranged along the axial direction of the slide rail 35. The pushing distance of the sample 100 can be obtained through the scale on the scale 36, so as to judge the position where it is inspected.

[0032] In this embodiment, the receiving cylinder 34 is rotated by 90° by the swing arm 32, that is, from the receiving position in the vertical position to the detection position in the horizontal position. The swing arm 32 is driven by a rotary cylinder 38. In some other embodiments, a receiving plate 33 linked to the receiving cylinder 34 can also be provided. When the hardness detection is not carried out, the sample coming from the previous process directly falls onto the receiving plate 33 and is sent to the next process without entering the receiving cylinder 34. In order to judge whether the sample 100 accurately enters the receiving cylinder 34, a feeding detection device 31 can also be provided.

[0033] As Figure 5 shown, in this embodiment, the detection module includes a weight assembly 42 for pressing the sample and a distance detection device 41 for measuring the distance by which the weight assembly 42 compresses the sample.

[0034] Specifically, the detection position of the sample branch is horizontal, and the pressing direction of the weight assembly 42 is vertical; the weight assembly 42 includes a weight body and a driving mechanism 46 for driving the weight body to move vertically; the weight body includes a loading weight 421 and a preloading weight 422, and the loading weight 421 is slidably connected to the driving mechanism 46 by a sleeve 423, so that the loading weight 421 can float up and down; the preloading weight includes a core rod 424 and a pressing head 422, the core rod 424 penetrates through the sleeve 423 and can slide along the axial direction of the sleeve 423; the pressing head 422 is connected to the lower end of the core rod 424 and extends out of the sleeve 423; the preloading weight can float up and down, and when the preloading weight floats up, the pressing head 422 can abut against the lower end of the sleeve 423.

[0035] When performing hardness detection, the driving mechanism 46 drives the weight body to move downward. Initially, due to gravity, the preloading weight 422 will extend downward and not contact the lower end of the sleeve 423. As the whole continues to descend, the preloading weight 422 first contacts the sample branch 100 to achieve preloading. The weight body continues to move downward. The preloading weight 422 cannot continue to move downward due to the obstruction of the sample branch 100, while the loading weight 421 will continue to move downward until the sleeve 423 on the loading weight 421 contacts the preloading weight 422, thereby jacking up the entire loading weight 421. At this time, the total weight of the entire loading weight 421 plus the preloading weight 422 falls on the sample branch 100. By detecting the displacement of the core rod 424 from the completion of preloading to when the total weight of the loading weight 421 and the preloading weight 422 falls on the sample branch 100 through the distance detection device 41, the amount of compression of the sample branch 100 can be obtained, and thus the hardness of the sample branch 100 can be calculated.

[0036] In some embodiments, the upper end of the sleeve 423 is a tapered sleeve with a larger upper part and a smaller lower part, and the upper end of the core rod 424 is a tapered body that fits with the tapered sleeve at the upper end of the sleeve 423 to prevent the core rod 424 from slipping out of the sleeve 423.

[0037] In some other embodiments, an air bearing 425 is provided between the sleeve 423 and the driving mechanism 46 to reduce the sliding resistance and make the measurement structure more accurate.

[0038] For the convenience of detection, the detection module further includes a load platform 43 for carrying the sample branch 100 for hardness detection, and the load platform 43 is located below the weight assembly 42. The sample branch 100 is pushed onto the load platform 43 by the pusher rod 310, and then the pressure is applied by the weight assembly 42 to complete the detection. It can be foreseen that, for the convenience of arrangement, an installation seat 44 for installing the load platform 43 is also included.

[0039] In order to detect whether the sample branch 100 is in place, a material in-place detection device 45 can also be provided. Of course, it is also possible to directly detect whether the sample branch 100 is in place through the detection module.

[0040] In this embodiment, the distance detection device 41 is preferably a laser ranging probe located above the weight mechanism 42, and the laser ranging probe detects the compression amount of the sample 100 by detecting the displacement of the detection core rod 424.

[0041] Of course, in order to facilitate the control of the entire device, a control center 12 can also be set up to operate the entire device through the human-machine interaction interface 21. In addition, the above-mentioned control center 12, detection module, and material transfer module can all be installed on the same reference installation panel 11.

[0042] The working process of the present utility model is as follows:

[0043] When the sample 100 enters from the previous process or is directly placed in the receiving cylinder 34 manually, the incoming material detection device 31 detects the sample 100, that is, the device switches from the standby mode to the working mode (note: in the standby mode, the receiving cylinder 34 is in the vertical receiving position, waiting for the sample 100 to enter).

[0044] Sample 100 enters the receiving cylinder 34 → The incoming material detection device 31 detects the sample 100 → Activates the "multi-point hardness measurement device" (note: switches from the standby mode to the working mode) → The rotary cylinder 38 works to drive the swing arm 32, causing the receiving plate 33 and the receiving cylinder 34 to change their postures by 90° and enter the detection position → After the magnetic induction sensor on the rotary cylinder 38 detects that the rotation is in place → The linear drive mechanism 39 works, causing the slider 37 on the slide rail to move, and pushing the sample 100 into the detection module 40 through the push rod (note: the distance for pushing the sample 100 can be set by the operator through the human-machine interaction operation interface 21 of the control center). → When the material in-place detection device 45 detects the sample 100 and meets the set pushing distance, the weight assembly 42 drives the sample 100 to be pre-compressed under the drive of the linear module of the drive mechanism 46 → After the pre-compression is completed, the formal pressure is applied → After both the pre-compression and the pressure application are completed, the laser detection probe 41 obtains a certain amount of measurement data through the relative displacement amount of the core rod in the weight assembly 42 → After measuring the hardness value of the sample 100, the air blowing hole on the mounting seat 44 blows out air to blow the sample 100 off the load platform 43 → Completes the hardness measurement work of one sample 100.

[0045] The above is only the preferred embodiment of the present utility model. It should be noted that the above preferred embodiment should not be regarded as a limitation of the present utility model. The protection scope of the present utility model should be subject to the scope defined by the claims. For those of ordinary skill in the art in this technical field, without departing from the spirit and scope of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
