Description

Technical Field

[0001] The present disclosure relates generally to the field of tobacco equipment, and more particularly to a fixing device and a detection device. Background Art

[0002] In the processing technology of tobacco production, tobacco materials need to go through a series of production processes such as loosening and rehydration, flavoring and adding materials, and flash evaporation. In these production processes, it is usually necessary to atomize the feed liquid used for tobacco materials into fine particles through a nozzle so that the feed liquid can be evenly attached to the tobacco materials. Therefore, the atomization of the nozzle directly affects the process quality of the tobacco materials, which further affects the quality and taste of the finished tobacco products prepared with the tobacco materials. If the atomization of the nozzle is too poor, the finished tobacco products will be downgraded and retained, or even the finished tobacco products will be scrapped, causing significant economic losses. Utility Model Content

[0003] A brief overview of the disclosure is given below in order to provide a basic understanding of some aspects of the disclosure. However, it should be understood that this overview is not an exhaustive overview of the disclosure. It is not intended to identify the key or important parts of the disclosure, nor is it intended to limit the scope of the disclosure. Its purpose is simply to give some concepts of the disclosure in a simplified form as a prelude to a more detailed description given later.

[0004] In the silk-making process of tobacco production, the nozzle usually atomizes and sprays the liquid inside a closed space such as a drum for conveying tobacco materials. Therefore, it is necessary to confirm whether the atomization of the nozzle meets the requirements to avoid affecting the quality of the processed tobacco materials. In the related art, production operators need to go to the site regularly to manually confirm the atomization of the nozzle. This manual observation method mainly judges the atomization of the nozzle based on the atomization of the nozzle seen by the production operator at a specific observation angle. Therefore, since it is impossible to fully observe the atomization of the nozzle, the accuracy of the atomization of the nozzle judged by the manual observation method is low.

[0005] In order to overcome the problem of low accuracy in judging the atomization condition of the nozzle in the related art, the embodiments of the present disclosure propose the following solution.

[0006] According to a first aspect of the present disclosure, a fixing device is provided, comprising: a retractable component, comprising a fixed portion and a movable portion mounted on the fixed portion and movable relative to the fixed portion; an angle adjustment seat, mounted on the movable portion and rotatable relative to the movable portion; and a video box for mounting a shooting device, mounted on the angle adjustment seat, the shooting device being configured to capture an image of atomization conditions of a nozzle for tobacco material.

[0007] In some embodiments, the movable part is sleeved on the fixed part, the movable part has a hole, and the movable part is mounted on the fixed part by a fastener passing through the hole.

[0008] In some embodiments, the angle adjustment seat is installed on the first surface of the movable part, and the angle adjustment seat can rotate at any angle relative to an axis perpendicular to the first surface.

[0009] In some embodiments, the fixing device further includes: a drop cover installed above the video box.

[0010] In some embodiments, the video box is completely covered by the drop cover when looking down at the fixture.

[0011] In some embodiments, the fixing device further comprises: a window protection cover installed at a position on the video box corresponding to the camera in the shooting device.

[0012] In some embodiments, the fixing device further includes: a light source protection cover installed at a position on the video box corresponding to the light source in the shooting device.

[0013] In some embodiments, the fixing device further comprises: a flexible wire tube, one end of the flexible wire tube is connected to the fixing portion, and the other end of the flexible wire tube is connected to the video box.

[0014] In some embodiments, the fixing device further includes: a junction box installed on the end surface of the fixing portion.

[0015] In some embodiments, the fixture is mounted on a bracket of the nozzle and is in the same horizontal plane as the nozzle.

[0016] According to a second aspect of the present disclosure, a detection device is provided, comprising: a fixing device as described in the first aspect of the present disclosure; a shooting device; and a control system, the control system receiving data of an image shot by the shooting device, and detecting atomization conditions of a nozzle based on the image data.

[0017] In some embodiments, the detection device also includes: an electronic control system electrically connected to the control system, the electronic control system transmits operating data to the control system, the operating data indicating whether the nozzle is in an operating state of spraying liquid; and the control system receives the operating data and controls the shooting device to shoot in response to the operating data indicating that the nozzle is in an operating state of spraying liquid.

[0018] In some embodiments, the control system transmits detection data to the electronic control system, the detection data indicating the atomization condition of the nozzle; and the electronic control system receives the detection data and, in response to the atomization condition of the nozzle not meeting the requirements, controls the nozzle to stop spraying the liquid.

[0019] In some embodiments, the detection device further includes: a pneumatic system electrically connected to the electronic control system, the pneumatic system providing a positive pressure environment to the video box in response to receiving a control signal from the electronic control system.

[0020] The advantage of the embodiments disclosed herein is that a fixing device with a simple structure, convenient use, and strong practicality is provided, the angle adjustment seat where the video box for mounting the shooting device is located can be rotated to adjust the angle of the shooting device, and the movable part of the retractable part where the angle adjustment seat is located can be moved relative to the fixed part to adjust the position of the shooting device. In this way, the fixing device can cooperate with the shooting device to shoot the atomization of the nozzle from different positions and angles, thereby facilitating the subsequent more accurate judgment of the atomization of the nozzle based on the images at different positions and angles.

[0028] Various exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0029] The following description of at least one exemplary embodiment is in fact merely illustrative and is in no way intended to limit the present disclosure and its application or use. That is, the structures and methods herein are shown in an exemplary manner to illustrate different embodiments of the structures and methods in the present disclosure. However, those skilled in the art will appreciate that they merely illustrate exemplary ways of the present disclosure that can be implemented, rather than exhaustive ways.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] The fixture according to various embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It is understood that the actual fixture may also include other components, but in order to avoid blurring the main points of the present disclosure, these other components are not discussed herein and the accompanying drawings are not shown. In addition, for reference purposes only, similar terms such as "first", "second", "third", "fourth" may also be used herein, and are therefore not intended to be limited. For example, unless the context clearly indicates, the words "first", "second", "third", "fourth" and other such numerical terms relating to structures or elements do not imply an order or sequence.

[0033] Figure 1 A schematic structural diagram of a fixing device 100 according to some embodiments of the present disclosure is shown.

[0034] like Figure 1 As shown, the fixing device 100 includes a retractable component 112 , and the retractable component 112 includes a fixing portion 1124 and a movable portion 1122 mounted on the fixing portion 1124 and movable relative to the fixing portion 1124 .

[0035] In some embodiments, the movable portion 1122 is sleeved on the fixed portion 1124, the movable portion 1122 has a hole 1122-2, and the movable portion 1122 is installed on the fixed portion 1124 by a fastener 1122-4 (such as but not limited to a bolt, a pin, etc.) passing through the hole 1122-2. For example, when it is necessary to adjust the shooting position of the shooting device, the fastener 1122-4 can be loosened first, and then the movable portion 1122 is moved to the desired position and then the fastener 1122-4 is inserted into the hole 1122-2 to fix the movable portion 1122. Therefore, it can also be considered that the length of the hole 1122-2 in the direction in which the movable portion 1122 moves indicates the range of the shooting position that the movable portion 1122 can adjust.

[0036] Understandable, although Figure 1 The hole 1122-4 shown in the figure is a whole long hole, but this is only exemplary and not restrictive. Those skilled in the art may also set the hole 1122-4 as a series of multiple holes with a certain spacing between adjacent holes or adopt any other form of structure to achieve the movement and fixation of the movable part 1122 relative to the fixed part 1124.

[0037] The number of fasteners 1122-4 passing through the hole 1122-2 may be Figure 1 The plurality of holes shown may also be one. In some embodiments, the movable portion 1122 has a plurality of holes 1122-2, and the movable portion 1122 is mounted on the fixed portion 1124 by a fastener 1122-4 passing through each hole 1122-2. For example, the movable portion 1122 has two holes 1122-2 arranged opposite to the fixed portion 1122, one or more fasteners 1122-4 passing through one of the holes 1122-2 are mounted on one surface of the fixed portion 1124, and one or more fasteners 1122-4 passing through the other hole 1122-2 are mounted on the other surface of the fixed portion 1124. In this way, the movable portion 1122 can be more firmly fixed to the fixed portion 1124.

[0038] Continue to refer Figure 1 The fixing device 100 further includes an angle adjustment seat 110 mounted on the movable portion 112 and rotatable relative to the movable portion 112. In some embodiments, the angle adjustment seat 110 is mounted on a first surface of the movable portion 112, and the angle adjustment seat 110 can rotate at any angle relative to an axis perpendicular to the first surface. Figure 1As shown, the angle adjustment seat 110 is mounted on the top surface 1122-6 of the movable part 112, and the angle adjustment seat 110 can be arbitrarily rotated within the range of 0° to 360° around an axis l perpendicular to the top surface 1122-6 of the movable part 112. When the spray angle of the nozzle changes, the movable part 112 can be rotated accordingly so that the shooting device to be described below follows the angle change of the nozzle, thereby ensuring the image integrity and usability of the atomization condition of the nozzle captured.

[0039] Continue to refer Figure 1 , the fixing device 100 also includes a video box 108 for installing a shooting device, the video box 108 is installed on the angle adjustment seat 110, and the shooting device (not shown in the figure) is configured to shoot an image of the atomization condition of the nozzle for tobacco material. As some implementations, the shooting device may include a light source (not shown in the figure) and a camera (not shown in the figure). As mentioned above, the nozzle is usually installed in or extends into a dark environment such as the inside of the drum. Therefore, in order to shoot an image that can indicate the atomization condition of the nozzle, it is necessary to provide certain lighting conditions for the camera. In some embodiments, the lighting range of the light source and the shooting range of the camera intersect the range of the liquid sprayed by the nozzle. In some embodiments, the video box 108 also has a first hole and a second hole corresponding to the positions of the camera and the light source, respectively, wherein the first hole allows the camera to capture images outside the video box 108, and the second hole allows the light of the light source to be emitted to the outside of the video box 108.

[0040] In the above embodiment, the video box 108 for mounting the shooting device is mounted on the angle adjustment seat 110, and the angle adjustment seat 110 is mounted on the movable part 1122 of the retractable part 112. When the position of the movable part 1122 is adjusted and / or the angle of the angle adjustment seat 110 is adjusted, the shooting position and / or shooting angle of the shooting device will change accordingly. Therefore, through the angle adjustment seat 110 and the retractable part 112, the shooting position and shooting angle of the shooting device can be flexibly adjusted, so as to capture various images of the atomization conditions of the nozzles desired by the production operators, which helps to improve the accuracy of the atomization conditions of the nozzles finally determined.

[0041] It should be noted that, since the shooting device is installed inside the video box 108, in this article, the position of the shooting device and the position of the video box 108 may not be distinguished.

[0042] In some embodiments, Figure 1As shown, the fixture 100 may further include a flexible wire tube 116, one end of which is connected to the fixture 1124, and the other end of which is connected to the video box 108. The flexible wire tube 116 may be used to protect various cables of the fixture 100 (for example, but not limited to, signal cables and power cables for cameras in the video box, power cables for light sources in the video box, etc.). As some implementations, the flexible wire tube 116 includes a material with high softness and deformability (for example, but not limited to rubber, plastic, elastomer, etc.), for example, the flexible wire tube 116 may be a metal snake tube, so as to avoid cable pulling caused by hard connection when the movable portion 1122 and / or the angle adjustment seat 110 are adjusted.

[0043] In some embodiments, Figure 1 As shown, the fixture 100 may further include a junction box 114 mounted on the end surface of the fixing portion 1124. The junction box 114 may be used to accommodate various cables of the fixture 100 (e.g., the signal cable and power cable for the camera and the power cable for the light source as described above) to facilitate the wiring installation of the fixture 100.

[0044] In some embodiments, the fixture 100 is mounted on a bracket of the nozzle and is on the same level as the nozzle. Figure 2 , Figure 2 The schematic diagram schematically shows the relative positional relationship between the nozzle 200, the nozzle bracket 202 (hereinafter referred to as the bracket 202), the junction box 114 and the fixing portion 1124. The position of the fixing portion 1124 can be used to represent the position of the fixing device 100. Therefore, when describing the positions of the nozzle 200 and the fixing device 100 on the bracket 202, the fixing portion 1124 and the fixing device 100 can be ignored. Figure 2As shown, the bracket 202 is located between the end surface of the junction box 114 and the fixing part 1124. For example, the fixing relationship between the junction box 114, the bracket 202 and the end surface of the fixing part 1124 can be formed by one or more of shape locking (such as snap-fitting), material locking (such as fasteners), force locking (such as bonding) and other connection methods that may achieve an effective fixing relationship. In addition, the nozzle 200 and the fixing part 1124 are on the same horizontal plane y so that when the nozzle 200 sprays the liquid, the fixing device 100 will not block the trajectory and area of ​​the liquid sprayed by the nozzle 200, and the nozzle 200 and the liquid sprayed by the nozzle 200 will not block the shooting device of the fixing device 100. Those skilled in the art can understand that since the nozzle 200 and the fixing device 100 are more complex structures in the actual tobacco production process, when the center of mass of the nozzle 200 and the center of mass of the fixing device 100 are on the same horizontal plane, it can be considered that the nozzle 200 and the fixing device 100 are on the same horizontal plane. Of course, it is understandable that those skilled in the art may also reasonably set the relative position relationship between the nozzle 200 and the fixture 100 according to actual processing conditions. For example, the nozzle 200 may also be located above the fixture 100 .

[0045] Combined with reference Figure 3 , Figure 3 A schematic diagram showing the relative positional relationship among the nozzle, the roller and the tobacco material according to some embodiments of the present disclosure. Figure 3 (a) is the main view. Figure 3 (b) is a side view. Figure 3 (c) is a top view. Figure 3 As shown, during the processing, the tobacco material 206 rotates counterclockwise in the drum 204. Similar to the nozzle 200, the fixing device 100 (including the camera) (not shown) except the junction box 114 extends into the drum 204, that is, the tobacco material 206 is likely to be thrown onto the fixing device 100 by the drum 204.

[0046] Therefore, in order to prevent the tobacco material 206 from covering the fixing device 100 (including the camera) and thus affecting the integrity of the image captured by the camera, in some embodiments, such as Figure 1 As shown, the fixture 100 may further include a drop cover 102 mounted above the video box 108 .

[0047] In some embodiments, when looking down (herein, looking from the drop cover 102 toward the retractable member 112 is considered “looking down”) on the fixture 100 , the video box 108 is completely covered by the drop cover 102 .

[0048] Furthermore, since the portion of the fixing device 100 other than the junction box 114 extends into the interior of the drum 204, in order to prevent the tobacco material 206 from damaging the camera during the rotation of the drum 204 and the material liquid sprayed by the nozzle 200 from affecting the electrical components and circuits inside the video box 108, in some embodiments, such as Figure 1 As shown, the fixing device 100 may further include a window protective cover 104 installed on the video box 108 at a position corresponding to the camera (not shown) in the shooting device. The window protective cover 104 has a transparent cover (for example, a transparent cover made of glass, acrylic, etc.) corresponding to the first hole on the aforementioned video box 108 so that the camera can capture the image outside the video box 108.

[0049] Furthermore, since the portion of the fixing device 100 other than the junction box 114 extends into the interior of the drum 204, in order to prevent the tobacco material 206 from damaging the light source during the rotation of the drum 204 and the liquid sprayed by the nozzle 200 from affecting the electrical components and circuits inside the video box 108, in some embodiments, such as Figure 1 As shown, the fixing device 100 may further include a light source protection cover 106 installed on the video box 108 at a position corresponding to the light source (not shown) in the shooting device. The light source protection cover 106 has a transparent cover (for example, a transparent cover made of glass, acrylic, etc.) corresponding to the second hole on the aforementioned video box 108 so that the light source can be emitted to the outside of the video box 108 through the second hole.

[0050] The present disclosure further provides a detection device in another aspect. Figure 4 FIG. 4 is a schematic diagram of a detection device 400 according to some embodiments of the present disclosure. Figure 4 As shown, the detection device 400 includes the fixing device 100 as described in any of the aforementioned embodiments of the present disclosure, a photographing device 410 for photographing an image of the atomization condition of the nozzle for tobacco material, and a control system 420.

[0051] The photographing device 410 includes a light source 412 and a camera 414 that provide certain lighting conditions for the camera 414. Various embodiments of the photographing device 410 are similar to the various embodiments of the photographing device described above, and therefore, the description of the various embodiments of the photographing device described above may be referred to and will not be repeated here.

[0052] The control system 420 receives the data of the image captured by the shooting device 410, and detects the atomization condition of the nozzle 200 based on the image data. For example, the control system 420 can be a host computer system that implements the functions of the above-mentioned embodiment, and the memory and processor of the host computer system can store and execute the corresponding image processing algorithm. This article does not specifically limit the specific image processing algorithm for detecting the atomization condition of the nozzle 200 based on the data of the captured image. It can be understood that any suitable image processing algorithm currently known or developed in the future can be stored and executed by the control system 420. In some embodiments, the control system 420 can communicate with the shooting device 410 through a wired method such as a signal cable, or can communicate with the shooting device 410 through a wireless method such as Bluetooth, Wi-Fi, Zigbee, etc. to transmit signals and data.

[0053] In the above embodiment, the detection device 400 is capable of analyzing and detecting the image of the atomization condition of the nozzle 200 for tobacco materials taken in real time, so that the production operator can remotely grasp the atomization condition of the nozzle 200 in real time, so that the production operator can promptly discover and correct the abnormal atomization condition of the nozzle 200, thereby ensuring the stability of the process quality of tobacco products and reducing the production cost of tobacco products.

[0054] In some embodiments, Figure 4 As shown, the detection device 400 may also include an electric control system 430 electrically connected to the control system 420. The electric control system 430 transmits operation data to the control system 420, and the operation data indicates whether the nozzle 200 is in an operation state of spraying liquid. The control system 420 receives the operation data and controls whether the shooting device 410 performs shooting according to the operation data. Specifically, in response to the operation data indicating that the nozzle is in an operation state of spraying liquid, the shooting device is controlled to shoot; otherwise, the shooting device is not controlled to shoot. For example, the liquid sprayed by the nozzle is provided by a flavoring machine. When the nozzle is in an operation state of spraying liquid, the flavoring machine is also in an operation state to transport liquid to the nozzle. Therefore, the operation data may include at least one of the data indicating that the flavoring machine is in an operation state and the liquid flow data. When the flavoring machine is in a non-operating state or the liquid flow data is zero, it means that the nozzle 200 is not in an operation state of spraying liquid. At this time, the control system 420 does not control the shooting device 410 to shoot. When the aromatizer is in operation or the liquid flow data is not zero, it means that the nozzle 200 is in the operation state of spraying liquid. At this time, the control system 420 controls the shooting device 410 to shoot.

[0055] In some embodiments, the control system 420 also transmits detection data to the electronic control system 430, and the detection data indicates the atomization condition of the nozzle 200; accordingly, the electronic control system 430 receives the detection data, and in response to the atomization condition of the nozzle 200 not meeting the requirements, controls the nozzle 200 to stop spraying the liquid. It can be understood that the production operator can reasonably set the requirements for the atomization condition of the nozzle 200 according to the actual tobacco processing technology. Further, in some embodiments, in response to the atomization condition of the nozzle 200 not meeting the requirements, the electronic control system 430 can also issue a warning to the production operator to remind the production operator to handle as soon as possible or directly interrupt the operation of the flavoring machine to stop providing the liquid to the nozzle 200. Therefore, when the detection device 400 detects that the atomization condition of the nozzle 200 does not meet the requirements, it can timely control the nozzle 200 to stop processing and remind the production operator to handle it to minimize the output of low-quality tobacco materials.

[0056] In some embodiments, the detection device 400 may further include a pneumatic system 440 electrically connected to the electronic control system 430. The pneumatic system 440 provides a positive pressure environment to the video box 108 in response to receiving a control signal from the electronic control system 430 (for example, in response to the drum 204 being turned on, the electronic control system 430 will send a signal to the pneumatic system 440 indicating that the pneumatic system 440 is started), so that the air pressure inside the video box 108 is higher than the air pressure outside the video box 108, thereby preventing dust particles inside the drum 204, finely divided parts of the tobacco material 208, and atomized particles of the liquid sprayed by the nozzle 200 from entering the interior of the video box 108 and causing damage to the shooting device 410, its internal electrical components and circuits.

[0057] The systems described in the above embodiments may be implemented by computer chips or entities, or by products with certain functions. A typical implementation device is a server system. Of course, the present disclosure does not exclude that with the development of computer technology in the future, the computer that implements the functions of the above embodiments may be, for example, a personal computer, a laptop computer, a vehicle-mounted human-computer interaction device, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
