Description

Technical Field

[0001] This utility model relates to the field of equipment cleaning technology, and in particular to a self-cleaning device for the imaging environment of a smoke spectral cleaning device. Background Technology

[0002] In the tobacco production and processing, the removal of impurities has a significant impact on cigarette production. During the tobacco leaf processing, various impurities mixed in with the tobacco leaves can damage processing equipment, and the cigarettes made from tobacco leaves contaminated with impurities will seriously affect the taste and have a negative impact on consumers' sensory evaluation.

[0003] Currently, machine vision inspection methods are relatively mature, and the tobacco industry has applied them to the impurity removal process of tobacco materials. However, visual inspection methods have strict requirements for the stability of the imaging environment. The stability of the imaging environment affects the acquired image samples, which in turn affects the detection of the machine vision inspection algorithm. If the imaging environment is unstable, it may lead to misjudgment by the visual inspection algorithm, reducing the removal rate of impurities and increasing the removal rate of non-impurities.

[0004] Poor image quality can be caused by a variety of factors, among which smoke dust adhering to the isolation plate of the background panel in smoke spectral cleaning equipment, and water stains remaining after moisture condensation, are the main contributors to image quality degradation. Cleaning these stains requires manual insertion of cleaning tools into narrow crevices, which cannot clean the entire isolation plate, leaving water stains in certain areas. Therefore, there is an urgent need for a self-cleaning device for the imaging environment of smoke spectral cleaning equipment to comprehensively clean stains in the imaging environment and improve image quality. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a self-cleaning device for the imaging environment of a smoke spectral cleaning equipment. This invention uses a cleaning cloth feeder to lay a cleaning cloth on an isolation plate, and then uses a telescopic cleaner to move the cleaning cloth to wipe the isolation plate, thereby improving the convenience and efficiency of cleaning.

[0006] The technical solution to the technical problem solved by this utility model is as follows:

[0007] This application provides a self-cleaning device for the imaging environment of a smoke spectral cleaning device. The smoke spectral cleaning device includes an imaging chamber, the bottom surface of which is an isolation plate. The self-cleaning device for the imaging environment includes a cleaning cloth feeder and a telescopic cleaner arranged opposite to each other. The telescopic cleaner is spaced above the isolation plate, and the cleaning cloth feeder is located outside the isolation plate.

[0008] The cleaning cloth feeder includes a rotating roller and a cutter. The cleaning cloth is wound around the rotating roller and extends toward the imaging chamber. The cutter is located above the cleaning cloth. The rotating roller brings the cleaning cloth into the imaging chamber and the cutter cuts the cleaning cloth as it moves down, so that the cleaning cloth falls onto the isolation plate.

[0009] The telescopic cleaner includes a cleaning drive, a telescopic rod, and a cloth fixing plate connected to the left end of the telescopic rod. The cleaning drive drives the cloth fixing plate to press down the cleaning cloth, and the cleaning drive also drives the telescopic rod to extend and retract, thereby moving the cloth fixing plate and wiping the isolation plate with the cleaning cloth.

[0010] As an improvement to the above solution, the cleaning fabric feeder includes a fabric box, the rotating roller and the cutter are both located inside the fabric box, the fabric box has an outlet, and the cleaning fabric extends from the outlet into the imaging chamber.

[0011] As an improvement to the above solution, a fabric discharge chamber is formed at the bottom of the fabric box, the lower edge of the outlet is flush with the partition plate, the fabric discharge chamber is located below the outlet, and the waste clean fabric on the partition plate falls into the fabric discharge chamber from the outlet.

[0012] As an improvement to the above solution, the telescopic rod includes a first rod, a second rod, a third rod, and a fixed section connected sequentially from left to right;

[0013] The cleaning drive unit includes a first transmission component, a second transmission component, and a third transmission component located inside the telescopic rod. The first transmission component drives the first rod to extend and retract, the second transmission component drives the second rod to extend and retract, and the third transmission component drives the third rod to move up and down, thereby driving the fabric fixing plate to move up and down.

[0014] As an improvement to the above solution, the cleaning drive unit further includes a first drive motor and a second drive motor located within the fixed section;

[0015] The first transmission assembly includes a first gear connected sequentially from right to left, and a first rack, a second rack, and a third rack arranged horizontally. The first drive motor is connected to the first gear. The first gear and the first rack mesh and drive each other. The first rack and the second rack mesh and drive each other through a pair of gears. The second rack and the third rack mesh and drive each other through another pair of gears. The left end of the third rack is connected to the first rod, thereby driving the first rod to extend and retract in the left and right directions.

[0016] The second transmission assembly includes a second gear, a fourth rack, and a fifth rack that are sequentially connected from right to left. The first drive motor is connected to the second gear. The fourth rack and the fifth rack are driven by a pair of meshing gears. The left end of the fifth rack is connected to the second rod, thereby driving the second rod to extend and retract in the left and right directions.

[0017] The third transmission component includes a sixth rack, which includes a horizontal connecting section and a vertical rack section connected to the right end of the horizontal connecting section. The left end of the horizontal connecting section is connected to the third rod. The second drive motor is connected to the vertical rack section. The second drive motor causes the sixth rack to move up and down through the gear and rack transmission method, thereby causing the fabric fixing plate to move down and press the cleaning fabric onto the isolation plate.

[0018] As an improvement to the above solution, the fabric fixing plate is arranged parallel to the isolation plate and its width is adapted to the width of the isolation plate, and the width of the cleaning fabric is equal to the width of the fabric fixing plate.

[0019] As an improvement to the above solution, the fabric fixing plate is connected to the first rod through a connecting plate, and the upper end face of the connecting plate is inclined to the left.

[0020] As an improvement to the above solution, the imaging environment self-cleaning device further includes a controller and a scanner located in the imaging chamber. The controller is communicatively connected to a data comparator, which stores spectral information of a clean isolation plate. The scanner scans the isolation plate and uploads its spectral information to the data comparator. The data comparator compares the current spectral information of the isolation plate with the stored spectral information of a clean isolation plate. If the comparison result indicates that stains have appeared on the isolation plate, the controller controls the cleaning cloth feeder to lay the cleaning cloth on the isolation plate and controls the telescopic cleaner to start the cleaning action.

[0021] As an improvement to the above solution, a reflector is also provided in the imaging chamber. The scanner is located in the upper part of the imaging chamber, and the reflector is located on the upper part of the opposite side of the scanner.

The telescopic rod extends and retracts, causing the cloth fixing plate to move left and right. Then, the partition plate is wiped by the cleaning cloth, realizing automatic and comprehensive cleaning of the partition plate, improving the convenience, efficiency and comprehensiveness of cleaning.

[0034] Example 1

[0035] See Figure 1-4 This embodiment provides a self-cleaning device for the imaging environment of a smoke spectral cleaning device, including a smoke spectral cleaning device 1. The smoke spectral cleaning device 1 includes an imaging chamber 1-1, and the bottom surface of the imaging chamber 1-1 is an isolation plate 1-2. The self-cleaning device for the imaging environment in this embodiment also includes a cleaning cloth feeder 2 and a telescopic cleaner 3.

[0036] The telescopic cleaner 3 is spaced above the partition plate 1-2, and the cleaning cloth feeder 2 is located outside the partition plate 1-2 and directly opposite the left side of the telescopic cleaner 3.

[0037] See Figure 4 and 5 The cleaning cloth feeder 2 includes an openable cloth box 2-1, a rotating roller 2-2 and a cutter 2-3 located inside the cloth box 2-1. Cleaning cloth 2-4 is wound around the rotating roller 2-2. An outlet 2-5 is provided on the right side of the cloth box 2-1 for the cleaning cloth 2-4 to extend into the imaging chamber 1-1. The vertically movable cutter 2-3 is positioned above the outlet 2-5. Driven by a first drive unit, the rotating roller 2-2 rotates, causing the cleaning cloth 2-4 to enter the isolation plate 1-2 inside the imaging chamber 1-1 through the outlet 2-5. Then, a second drive unit 2-6 drives the cutter 2-3 downwards to cut the cleaning cloth 2-4, causing the cut cleaning cloth 2-4 to fall onto the isolation plate 1-2. The length (left-right distance) of the cleaning cloth 2-4 is one-fifth the width of the isolation plate 1-2, and its width (front-back distance) matches the width of the isolation plate 1-2. Among them, the first driving component and the second driving component 2-6 are both drive motors. The drive motor that drives the cutter 2-3 drives the cutter 2-3 to move up and down through gear and rack transmission.

[0038] Furthermore, the lower edge of the outlet 2-5 is flush with the partition plate 1-2, and the outlet 2-5 forms a cloth discharge cavity 2-7 for storing waste cleaning cloth 2-4; after the cleaning process is completed, the telescopic cleaner 3 extends to the left to push the cleaning cloth 2-4 out of the imaging part and falls from the outlet 2-5 into the cloth discharge cavity 2-7.

[0039] See Figure 6 and 7The telescopic cleaner 3 includes a cleaning drive component, a telescopic rod, and a cloth fixing plate 3-5 connected to the left end of the telescopic rod. The cloth fixing plate 3-5 is arranged parallel to the isolation plate 1-2, and its width is adapted to the width of the isolation plate 1-2, that is, the width of the cloth fixing plate 3-5 is equal to the width of the cleaning cloth 2-4. The cleaning drive component drives the telescopic rod to extend to the left, so that the cloth fixing plate 3-5 is above the cleaning cloth 2-4 on the isolation plate 1-2. The cleaning drive component then drives the telescopic rod and the cloth fixing plate 3-5 to move downward as a whole, causing the cloth fixing plate 3-5 to press down so that the cleaning cloth 2-4 is tightly attached to the isolation plate 1-2. The extension and retraction of the telescopic rod causes the cloth fixing plate to move left and right, thereby wiping the isolation plate 1-2 with the cleaning cloth 2-4. The friction between the cloth fixing plate 3-5 and the cleaning cloth 2-4 is greater than the friction between the cleaning cloth 2-4 and the isolation plate 1-2, which can prevent the cleaning cloth 2-4 from sliding or falling off during the cleaning process, thereby maintaining its stability on the cloth fixing plate 3-5.

[0040] Specifically, the telescopic rod includes a first rod 3-1, a second rod 3-2, a third rod 3-3, and a fixed section 3-4 connected sequentially from left to right. The first rod 3-1 and the second rod 3-2 can extend and retract left and right, and the third rod 3-3 can move up and down relative to the fixed section 3-4. When cleaning is not required, the first rod 3-1 and the second rod 3-2, after retracting, together with the fabric fixing plate 3-5 and the third rod 3-3, are located in the redundant space on the right side of the imaging chamber 1-1, without affecting the imaging environment of the smoke spectral cleaning device 1. The fixed section 3-4 can be located in the redundant space inside the imaging chamber or outside the imaging chamber 1-1.

[0041] The cleaning drive unit includes a first transmission assembly, a second transmission assembly, and a third transmission assembly located inside the telescopic pole. The cleaning drive unit also includes a first drive motor 3-7 and a second drive motor 3-8 located within the fixed section 3-4.

[0042] The first transmission assembly includes a first gear 3-9 connected sequentially from right to left, and a horizontally arranged first rack 3-10, second rack 3-11, and third rack 3-12. A first drive motor 3-7 is connected to the first gear 3-9. The first gear 3-9 and the first rack 3-10 mesh, and the first rack 3-10 and the second rack 3-11 are connected by a pair of gears. The second rack 3-11 and the third rack 3-12 are connected by another pair of gears. The left end of the third rack 3-12 is connected to the first rod 3-1, thereby driving the first rod 3-1 to extend and retract in the left-right direction.

[0043] The second transmission assembly includes a second gear 3-13, a fourth rack 3-14, and a fifth rack 3-15 connected sequentially from right to left. A first drive motor 3-7 is connected to the second gear 3-13. The fourth rack 3-14 and the fifth rack 3-15 are driven by a pair of meshing gears. The left end of the fifth rack 3-15 is connected to the second rod 3-2, thereby driving the second rod 3-2 to extend and retract in the left-right direction.

[0044] The third transmission assembly includes a sixth rack 3-16, which comprises a horizontal connecting section and a vertical rack section connected to the right end of the horizontal connecting section. The left end of the horizontal connecting section is connected to the third rod 3-3. The second drive motor 3-8 is connected to the vertical rack section via a gear and rack transmission. The second drive motor 3-8 causes the sixth rack 3-16 to move up and down through the gear and rack transmission, which in turn causes the third rod 3-3 to move up and down, thereby causing the fabric fixing plate 3-5 to move down and press the cleaning fabric 2-4 onto the isolation plate 1-2.

[0045] During operation, the first drive motor 3-7 starts, driving the first gear 3-9 and the second gear 3-13 to move. The rotation of the first gear 3-9 drives the first rack 3-10 to move, transmitting power to the second rack 3-11 through a pair of gears. The second rack 3-11, under the rotation of another pair of gears, drives the third rack 3-12 to move, thereby causing the first rod 3-1 to extend and retract in the left and right directions. The second gear 3-13 drives the second rod 3-2 to extend and retract in the left and right directions through the same meshing transmission method. In addition, when the first rod 3-1 and the second rod 3-2 are fully extended to the left, the cloth fixing plate 3-5 is located directly above the cleaning cloth 2-4. The third transmission component then operates, and the third rod 3-3 drives the cloth fixing plate 3-5 to move down, pressing the cleaning cloth 2-4 tightly onto the isolation plate 1-2.

[0046] The fabric fixing plate 3-5 is connected to the first rod 3-1 through the connecting plate 3-6. The upper end face of the connecting plate 3-6 is tilted to the left so that the telescopic rod can extend and retract sequentially without touching the isolation plate 1-2.

[0047] Example 2

[0048] This embodiment is basically the same as Embodiment 1 above, except that:

[0049] The imaging environment self-cleaning device in this embodiment also includes a controller, a scanner 1-3, a reflector 1-4, and a light source 1-5 located in the imaging chamber 1-1. The scanner 1-3 is located at the upper part of the imaging chamber 1-1, and the reflector 1-4 is located at the upper part of the opposite side of the scanner 1-3. The controller is communicatively connected to a data comparator, which stores the spectral information of the clean isolation plate 1-2.

[0050] Scanner 1-3 emits infrared light through an infrared emitter onto reflector 1-4, which then illuminates the isolation plate 1-2. The infrared light reflected by the isolation plate 1-2 illuminates an infrared receiver, scanning the isolation plate 1-2 and uploading its spectral information to a data comparator. The data comparator compares the current spectral information of the isolation plate 1-2 with the stored spectral information of a clean isolation plate 1-2 to determine residual dirt. If the determination result indicates that stains are detected on the isolation plate 1-2, the controller controls the cleaning cloth feeder 2 to lay the cleaning cloth 2-4 onto the isolation plate 1-2 and controls the telescopic cleaner 3 to start the cleaning operation.

[0051] It should be noted that the controller in this application simply uses a PLC control system to perform data comparison of spectral information and start / stop control of the cleaning fabric feeder and the telescopic cleaner (specifically, a Siemens S7-414 PLC controller can be used). Data comparison and start / stop control based on a PLC control system are already quite mature technologies in the prior art. This embodiment does not intend to, and does not involve, any improvement to the microcontroller control board itself, the microcontroller control program, or the computer program. Any existing microcontroller control technology that can achieve the data communication, numerical comparison, and other functions of this embodiment should be applicable to this embodiment.

[0052] It should also be noted that, in this embodiment, directional terms such as up, down, left, right, front, and back are all in the form of... Figure 2 Based on.

[0053] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
