Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette production, in particular to a copper chain cleaning method. BACKGROUND

[0002] In the production process of cut tobacco, the cutting process is an important link to ensure the quality of cut tobacco, and the feeding module of the cutting machine (i.e. the copper chain conveying device of the cutting machine) is a key component to ensure the uniformity of cut tobacco. In the actual production process, the material is between the upper copper chain and the lower copper chain, and the cutting machine equipment will exert a large extrusion force on the material. Therefore, the tobacco dust, fragments, tobacco oil and tobacco scale in the material are easy to adhere to the surface of the copper chain and accumulate in the grooves of the copper chain, causing abnormal phenomena such as jamming, deformation, bulging, deviation and misplacement of the copper chain during operation, affecting the feeding effect, and further causing uneven cut tobacco, which seriously affects the quality of cut tobacco. In addition, the deformation of the copper chain also causes serious wear of the cutting machine and the copper chain, resulting in shutdown of the cutting machine due to failure, and increasing the maintenance cost of the equipment.

[0003] Therefore, in order to ensure the quality of cut tobacco and reduce machine wear, production workshop personnel generally clean the surface of the copper chain with a steel wire brush, scraper and other tools after production ends each day or when the cigarette brand is changed, and remove the tobacco dust and other residues in the grooves of the copper chain. However, since the number of grooves of the copper chain is large, generally up to three or four hundred, and each time the manual cleaning needs the operator to hold a steel wire brush or scraper and clean repeatedly along the direction of the grooves, which is time-consuming and labor-intensive, resulting in low cleaning efficiency of the copper chain. SUMMARY

[0004] The present application aims to solve the technical problem of low efficiency of manual cleaning of the copper chain in the prior art. To solve this problem, the present application provides a copper chain cleaning method, which can automatically clean the grooves on the surface of the copper chain, improve the cleaning efficiency of the copper chain, and more conveniently ensure the cleaning effect of the copper chain by using mechanical cleaning instead of manual operation.

[0005] To solve the above technical problem, the embodiments of the present application disclose a copper chain cleaning method based on a copper chain cleaning system comprising a cleaning module. The cleaning module comprises a scraper provided with a plurality of protrusions arranged along a straight line at intervals. The shape of each protrusion matches the shape of the groove of the copper chain so that the protrusion can extend into the groove to clean the groove. The copper chain cleaning system stores the number of cleaning times. The copper chain cleaning method comprises:

[0006] A first moving step: driving the cleaning module to move to a preset position;

[0007] A position detection step: detecting whether the scraper and the corresponding groove of the copper chain are in the same vertical plane. If yes, the next step is executed.

[0008] The second moving step is to drive the cleaning module to ascend in the vertical direction to the cleaning position so that each protrusion extends into the corresponding groove;

[0009] The cleaning step is to drive the scraper to repeatedly move in the first direction so that each protrusion cleans the corresponding groove;

[0010] The moving resetting step is to stop the movement of the scraper in the first direction, drive the cleaning module to move to the preset position, and drive the copper bar chain to move forward by the preset distance when the movement time of the scraper reaches the target movement time or the movement times of the scraper reach the target movement times.

[0011] The judging step is to judge whether the cleaning times stored in the copper bar chain cleaning system are greater than or equal to the set cleaning times after the cleaning times are accumulated by 1, and if yes, the cleaning times stored in the copper bar chain cleaning system are cleared; otherwise, the first moving step is returned.

[0012] In the cleaning process, the copper bar chain is intermittently moved, the cleaning module cleans a section of the copper bar chain each time, the copper bar chain is moved by a distance, and the relative positions of the grooves of the copper bar chain and the cleaning module are detected through the feedback mechanism. When each protrusion on the cleaning module extends into the corresponding groove, the cleaning is started, each protrusion repeatedly moves in the corresponding groove of the copper bar chain surface to clean the residues in the groove, and when the cleaning of the current section of the copper bar chain is completed, the copper bar chain is automatically operated to move the next section of the adjacent copper bar chain to the cleaning area for automatic cleaning. The scheme greatly improves the cleaning effect and efficiency.

[0013] Optionally, in the copper bar chain cleaning method provided in the embodiment of the application, after the moving resetting step and before the judging step, the method further includes:

[0014] The cleaning detection step is to collect the image of the cleaned groove, judge whether the cleaning is in place according to the collected image, and if yes, the next step is executed; otherwise, an alarm is sent to remind the operator whether to clean again. If the operator chooses to clean again, the copper bar chain is driven to move reversely by the preset distance and then the position detection step is returned.

[0015] Optionally, in the copper bar chain cleaning method provided in the embodiment of the application, the copper bar chain cleaning system further stores a cleaning reference image.

If they are in the same vertical plane, the next step is performed; otherwise, the copper bar chain is driven to run in reverse to adjust the relative position of the protrusion on the scraper and the corresponding groove to be in the same vertical plane.

[0047] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0048] The application provides a copper bar chain cleaning method, which can be performed based on a copper bar chain cleaning system comprising a cleaning module, the cleaning module comprising a scraper provided with a plurality of protrusions arranged in a straight line at intervals, the shape of each protrusion being matched with the shape of a groove of the copper bar chain so that the protrusion can extend into the groove to clean the groove, and the copper bar chain cleaning system storing a cleaning number. Specifically, the copper bar chain cleaning method comprises: driving the cleaning module to move to a preset position; detecting whether the scraper and the corresponding groove of the copper bar chain are in the same vertical plane, if yes, driving the cleaning module to ascend to a cleaning position in the vertical direction so that each protrusion extends into the corresponding groove; driving the scraper to repeatedly move in a first direction so that each protrusion cleans the corresponding groove; when the movement time of the scraper reaches a target movement time or the movement number of the scraper reaches a target movement number, controlling the scraper to stop moving in the first direction, and driving the cleaning module to move to the preset position, and driving the copper bar chain to move forward by a preset distance; after the cleaning number stored in the copper bar chain cleaning system is added by 1, judging whether the cleaning number is greater than or equal to a set cleaning number; if yes, resetting the cleaning number stored in the copper bar chain cleaning system to 0; otherwise, returning to execute the above steps.

[0049] Specifically, the preset distance is equal to the distance between the two protrusions farthest apart in the extension direction of the scraper.

[0050] Further, the set cleaning number can be calculated according to the total length of the copper bar chain and the length of the scraper, and the set cleaning number satisfies the following relationship:

[0051]

[0052] wherein, is a floor function, x is a floor of x, M represents the set cleaning number, L represents the total length of the copper bar chain, S represents the length of the scraper, and a represents an adjustment parameter, 0 < a ≤ 1.

[0053] In the execution of the cleaning process, the copper bar chain adopts intermittent motion, after the cleaning module finishes cleaning a section of the copper bar chain, the copper bar chain moves a distance, and through the feedback mechanism, when each protrusion on the cleaning module extends into the corresponding groove, the cleaning is started, each protrusion repeatedly moves in the corresponding groove of the copper bar chain surface to clean the residues in the groove, and when a section of the copper bar chain is cleaned, the copper bar chain is automatically operated to move the next adjacent copper bar chain to the cleaning area for automatic cleaning. The present application greatly improves the cleaning effect and efficiency.

[0054] The copper bar chain cleaning method of the application will be described below.

[0055] Reference Figures 1 to 5The copper busbar chain cleaning system includes a cleaning module 1, a control module 8, a drive module, and a camera module 5, wherein the drive module and the camera module 5 are electrically connected to the control module 8.

[0056] Specifically, the drive module is connected to the cleaning module 1 and can be used to drive the cleaning module 1 to move away from or towards the copper busbar chain 201. Further, the drive module includes a second horizontal drive mechanism 2 and a vertical drive mechanism 3. The second horizontal drive mechanism 2 can drive the cleaning module 1 along a second direction (…). Figure 3 and Figure 5 (As shown in the Y direction) the vertical drive mechanism 3 can drive the cleaning module 1 along the vertical direction (as shown in the Y direction) to move. Figure 1 , Figure 3 and Figure 5 (As shown in the Z-direction). The camera module 5 can be used to acquire images of its area (hereinafter referred to as the image acquisition area) and transmit the acquired images to the control module 8 so that the control module 8 can analyze and process the images.

[0057] For example, such as Figure 3 As shown, the cleaning module 1 includes a cleaning drive unit 103 and a plurality of protrusions 10221 arranged in a straight line at intervals. The shape of each protrusion 10221 matches the shape of the groove 2011 of the copper busbar chain 201 so that the protrusion 10221 can extend into the groove 2011. The cleaning drive unit 103 can drive each protrusion 10221 in its corresponding groove 2011 along a first direction ( Figure 1 , Figure 3 and Figure 5 The copper busbar chain (shown in the X direction) moves repeatedly to clean the groove 2011. Specifically, during the cleaning process of the copper busbar chain cleaning system, the copper busbar chain 201 operates intermittently, and each movement covers a preset distance. That is, after cleaning each section of the copper busbar chain, the chain moves forward a preset distance so that the next section to be cleaned moves to the cleaning area. Specifically, the preset distance is less than or equal to the distance between the two furthest protrusions 10221 along the extension direction of the scraper (i.e., the second direction), so as to ensure that the groove of each copper busbar chain can be cleaned.

[0058] Generally, the length of the copper strip chain 201 is longer, and the length (or number) of each protrusion 10221 on the cleaning module 1 is limited, so the cleaning of the copper strip chain 201 is usually completed in multiple times. Specifically, the cleaning module 1 can be arranged to be substantially unchanged in the second direction and the vertical direction during each cleaning, and the protrusions 10221 on the module only clean the grooves 2011 on the surface of the copper strip chain 201 in the cleaning area. After the grooves 2011 on the current copper strip chain 201 in the cleaning area are cleaned, the copper strip chain 201 is run forward, so that the next section of the copper strip chain 201 moves to the cleaning area to perform cleaning on the section of the copper strip chain 201. Specifically, after a section of the copper strip chain 201 in the cleaning area is cleaned, the cleaning module retreats to a preset position, and the copper strip chain 201 is run forward by a preset distance, so that the section of the copper strip chain 201 that has been cleaned moves out of the cleaning area, and the next section of the copper strip chain 201 adjacent to it moves to the cleaning area. Then the cleaning module 1 moves to the preset position first, and then moves upward so that the protrusions 10221 on the cleaning module 1 extend into the grooves 2011 of the copper strip chain 201 in the cleaning area. Then the cleaning drive part 103 drives each protrusion 10221 to repeatedly move in the groove 2011, and the accumulated residues such as soot and oil in the groove 2011 are removed by the friction between the protrusion 10221 and the groove 2011. Specifically, in order to balance the cleaning effect and cleaning efficiency, the preset distance of the copper strip chain 201 running each time is equal to the distance between the two protrusions 10221 farthest apart.

[0059] The cleaning module 1, the driving module 2 and the camera module 5 constitute a copper strip chain cleaning assembly 100. During specific cleaning, the copper strip chain cleaning assembly 100 is arranged below the copper strip chain. Specifically, as shown in Figure 2 The copper strip chain cleaning system further comprises a support module 6, the cleaning module 1 is installed on the support module 6, and the support module 6 is further used to connect with the rack 202 of the tobacco cutting machine, so that the cleaning system is fixedly installed on the tobacco cutting machine to facilitate the cleaning of the copper strip chain 201 of the tobacco cutting machine.

[0060] Specifically, the cleaning module 1 further comprises a fixing part 101. The fixing part 101 is connected with the support module 6, so that the cleaning module 1 can be installed on the support module 6.

[0061] Specifically, the cleaning drive part 103 can reciprocate relative to the fixing part 101 along a first direction between a first cleaning position and a second cleaning position, wherein the first direction is perpendicular to the extension direction of the copper strip chain 201 (i.e. the second direction). That is, the protrusions 10221 can move vertically relative to the extension direction of the groove 2011 in the groove 2011, so as to facilitate the cleaning of the inner surface of the groove 2011.

[0062] Exemplarily, the relative reciprocating motion between the cleaning driving part 103 and the fixed part 101 can be realized by the form of the gear 1032 and the rack 1011. Specifically, the fixed part 101 comprises the rack 1011 arranged along the first direction, the cleaning driving part 103 comprises the motor 1031 and the gear 1032 engaged with the rack 1011, the motor 1031 is connected with the control module 8, and the output end of the motor 1031 is connected with the gear 1032, and the gear 1032 can reciprocate along the first direction relative to the rack 1011 under the driving of the motor 1031.

[0063] Specifically, as shown in the figure, Figure 3 the fixed part 101 comprises a strip arranged along the first direction, the side of the strip is provided with the rack 1011 extending along the first direction, the cleaning driving part 103 comprises the motor 1031, the bottom of the motor 1031 is mounted on the bottom plate, and the output end of the motor 1031 penetrates through the bottom plate and is connected with the gear 1032, and the cleaning part 102 is mounted on the bottom plate. When the motor 1031 operates, the output end of the motor 1031 drives the gear 1032 to rotate, since the gear 1032 is engaged with the rack 1011 and the rack 1011 is fixed relative to the support module 6, the gear 1032 moves along the first direction, and simultaneously drives the mounting plate and the cleaning part 102 and the motor 1031 on the mounting plate to move along the first direction synchronously, and by adjusting the forward rotation and the reverse rotation of the motor 1031, it can be realized that the gear 1032 moves forward along the first direction or reversely along the first direction. In actual operation, the forward rotation and the reverse rotation time of the motor 1031 can be set according to actual situation to realize the cleaning of the protrusion 10221 to the groove 2011.

[0064] Exemplarily, the cleaning module 1 further comprises the cleaning part 102, and the cleaning part 102 comprises the support plate 1021, the scraper 1022 and the fastener.

[0065] Specifically, the support plate 1021 has a certain length in the second direction, and the first end of the support plate 1021 is provided with the first mounting hole, wherein the end of the support plate 1021 close to the copper bar chain 201 is the first end. The second mounting hole 1023 is further provided on the scraper 1022, and the scraper 1022 is mounted on the support plate 1021 through the fastener penetrating through the second mounting hole 1023 and the first mounting hole. Optionally, the scraper 1022 can be a finger plate, that is, the top of the scraper 1022 is provided with the protrusion 10221, and the protrusion 10221 is in the shape of a finger, and the scraper 1022 in this shape can facilitate the cleaning of the groove 2011.

[0066] Specifically, by setting the first mounting hole and the second mounting hole 1023, the position of the scraper 1022 on the support plate 1021 can be adjusted according to actual conditions, so as to facilitate the subsequent cleaning of the protrusions 10221 on the scraper 1022 to the groove 2011. Optionally, the first mounting hole and / or the second mounting hole 1023 are also holes extending in the second direction, which can be a waist-shaped hole, a strip-shaped hole, etc. In some other embodiments of the present application, the first mounting hole and / or the second mounting hole 1023 can also be several holes arranged at intervals. Specifically, the first mounting hole and / or the second mounting hole 1023 can be one or more rows of holes arranged at intervals in the second direction, and when it is necessary to adjust the position of the scraper 1022 on the support plate 1021, only need to correspond the second mounting hole 1023 on the scraper 1022 with a corresponding hole in the first mounting hole, and then lock it through a fastener (such as a bolt).

[0067] As shown in Figure 3 and Figure 4 , the vertical driving mechanism 3 is connected with the fixed part 101 of the cleaning module 1, and is used to drive the cleaning module 1 to move in the vertical direction, so that each protrusion 10221 extends into its corresponding groove 2011 (as shown in Figure 7 ) or separates from the corresponding groove 2011.

[0068] Specifically, the copper strip chain cleaning system can be arranged below the copper strip chain 201 of the tobacco cutting machine, and the vertical driving mechanism 3 can drive the cleaning module to move to the lowest limit position (below the copper strip chain). When the copper strip chain 201 is running, the copper strip chain cleaning system below the copper strip chain 201 can have a certain distance with the copper strip chain 201, so as not to affect the running of the copper strip chain 201; and when the copper strip chain needs to be cleaned, the copper strip chain 201 to be cleaned is run to the cleaning area, the cleaning part 102 is lifted by the vertical driving mechanism 3 so that the protrusions 10221 thereon can extend into the groove 2011, and then the protrusions 10221 are driven by the cleaning driving part 103 to move repeatedly in the groove 2011 to remove the accumulated soot and other substances in the groove 2011. Optionally, the vertical driving mechanism 3 is a pneumatic cylinder, and the fixed part 101 of the cleaning module 1 is connected with the output end of the pneumatic cylinder.

[0069] In addition, the advantage of setting the vertical driving mechanism 3 also lies in that when the protrusions 10221 complete the cleaning of a certain section of the copper strip chain 201, the vertical driving mechanism 3 can drive the cleaning module 1 to move in the second direction so that the protrusions 10221 separate from the groove 2011, so as to facilitate the movement of the copper strip chain 201 or the movement of the cleaning system.

[0070] Specifically, the second horizontal driving mechanism 2 is connected with the cleaning module 1, and is used to adjust the relative position of the cleaning module 1 and the copper strip chain 201 in the second direction, so that each protrusion 10221 can be in the same vertical plane with its corresponding groove.

[0071] Specifically, the second horizontal driving mechanism 2 comprises a second driving part 21, a second sliding block 22 and a second sliding rail 23. The second sliding rail 23 extends along the third direction, the second sliding block 22 is slidably arranged on the second sliding rail 23, the number of the second sliding rails 23 is two, and the second sliding rails 23 are arranged along the first direction at intervals. Each of the second sliding rails 23 is slidably arranged with a second sliding block 22, and the second driving part 21 is arranged between the two second sliding rails 23. The fixing part 101 of the cleaning module 1 is fixedly installed on the upper end faces of the second driving part 21 and the second sliding block 22, and the output end of the second driving part 21 is connected with the fixing part 101 of the cleaning module 1, so that the second driving part 21 can drive the fixing part 101 to move along the third direction.

[0072] Specifically, as shown in Figure 5 and Figure 3 The second driving part 21 can be a lead screw driving device, which comprises a lead screw 211, a lead screw driving motor 212 and a connecting part with a threaded sleeve arranged on the lead screw. The lead screw 211 is connected with the lead screw driving motor 212, the extension direction of the lead screw 211 is parallel to the extension direction of the copper strip chain 201, the entire cleaning module 1 is connected to the upper end face of the connecting part through the mounting plate, and the upper end face of the second sliding block 22 is also connected with the bottom end of the cleaning module 1. The lead screw driving motor 212 drives the lead screw 211 to rotate, so as to drive the connecting part, the second sliding block 22 connected with the connecting part and the cleaning mechanism to move along the extension direction of the copper strip chain 201, thereby adjusting the position of the cleaning module 1 along the third direction on the supporting module 6.

[0073] Exemplarily, the second driving part 21 is also electrically connected with the control module 8.

[0074] Exemplarily, the copper strip chain cleaning system can further comprise a first horizontal driving mechanism 4 connected with the cleaning module 1, and the first horizontal driving mechanism 4 is used to drive the cleaning module 1 to move along the first direction. In this way, the collision between the cleaning system and the copper strip chain 201 can be further prevented.

[0075] Specifically, as shown in Figure 6 The first horizontal driving mechanism 4 comprises a first sliding rail 41 extending along the first direction and a first sliding block 42 slidably arranged on the first sliding rail 41, and the upper end face of the first sliding block 42 is connected with the cleaning part 102 through the bottom plate 104. The first sliding block 42 is connected with a first driving motor, so as to drive the first sliding block 42 to slide along the first sliding rail 41.

[0076] The copper bar chain cleaning system provided by the application adopts a power cleaning device to scrape and clean the residues in the grooves 2011 on the surface of the copper bar chain 201, wherein the scraper 1022 adopts a finger plate form, facilitating the cleaning of the residues in the grooves 2011. During the cleaning process, since the length of the scraper 1022 on the cleaning part 102 is limited, each time of cleaning can only be performed on a section of the copper bar chain 201, and therefore, the intermittent movement of the copper bar chain 201 can be adopted. After the scraper 1022 completes the cleaning of a section of the copper bar chain 201 each time, the copper bar chain 201 moves by a distance equal to the length of the scraper 1022. The relative distance between the grooves 2011 on the copper bar chain 201 and the scraper 1022 is detected by the camera module 5, and then the position of the protrusion 10221 on the scraper 1022 is adjusted to correspond to the position of the groove 2011 on the copper bar chain 201 by the positioning and adjusting module. Then, the protrusion 10221 is extended into the groove 2011 on the surface of the copper bar chain 201 (as shown in Figure 2 Fig. 6) by the vertical driving mechanism 3, and the protrusion 10221 is repeatedly moved in the groove 2011 on the surface of the copper bar chain 201 by the cleaning driving part 103 to clean the residues in the groove 2011.

[0077] Further, the control module 8 of the copper bar chain cleaning system stores the number of cleaning times, as shown in Figure 8 Fig. 6. The copper bar chain cleaning method provided by the application includes the following steps:

[0078] The first moving step S1: driving the cleaning module to move to a preset position.

[0079] Specifically, the step S1 can be performed by the control module 8, the second horizontal driving mechanism 2 and the vertical driving mechanism 3. The control module 8 first controls the vertical driving mechanism 3 to drive the cleaning module 1 to descend to the lowest limit position along the vertical direction, and then controls the second horizontal driving mechanism 2 to drive the cleaning module 1 to move to the preset position along the second direction; wherein the first direction, the second direction and the vertical direction are perpendicular to each other.

[0080] The position detection step S2: detecting whether the scraper and the corresponding groove on the copper bar chain are in the same vertical plane, and if yes, performing the next step.

[0081] Specifically, the control module 8 also stores the original position image. The above position detection step specifically includes: the camera module 5 collects the image in the image collection area, transmits the collected image to the control module 8, and compares the received image with the original position image in the control module 8 to determine whether the scraper and the corresponding groove on the copper bar chain are in the same vertical plane. If yes, the next step is performed, otherwise, the copper bar chain is driven to run reversely at a low speed to adjust the relative position of the protrusion on the scraper and the corresponding groove to be in the same vertical plane.

[0082] Specifically, the camera module 5 can include an image acquisition terminal, which can feed the collected images or videos to a display device in real time to facilitate personnel to watch and master the cleaning site situation. Further, the image acquisition terminal is composed of a camera, lighting and other components, and is installed on the automatic cleaning device rack in a static state. When installed, the image acquisition terminal is installed forward with the copper chain running direction as a reference.

[0083] The second moving step S3: the control module 8 controls the vertical driving mechanism 3 to drive the cleaning module 1 to ascend in the vertical direction to the cleaning position so that each protrusion extends into the corresponding groove.

[0084] Specifically, when the cleaning module 1 ascends in the vertical direction to the cleaning position so that each protrusion extends into the corresponding groove, the camera module can collect the images in the image acquisition area, and the control module can compare the images with the cleaning position comparison images to determine whether the protrusion extends into the corresponding groove.

[0085] Specifically, the cleaning position comparison image and the origin position comparison image can be obtained by the following steps:

[0086] Manually operating the vertical driving mechanism to drive the cleaning module to descend in the vertical direction to the lowest limit position;

[0087] Manually operating the second horizontal driving mechanism to drive the cleaning module to run in the second direction to the midpoint position;

[0088] Manually operating the vertical driving mechanism to drive the cleaning module to ascend in the vertical direction, and adjusting the vertical driving mechanism and the second horizontal driving mechanism to make the protrusion fit with the corresponding groove;

[0089] The camera module 5 collects the images in the image acquisition area and transmits them to the control module 8 for storage as cleaning position comparison images;

[0090] Manually operating the vertical driving mechanism to drive the cleaning module to descend in the vertical direction to the lowest, and the camera module 5 collects the images at this position and transmits them to the control module 8 for storage as origin position comparison images.

[0091] The cleaning step S4: driving the scraper to move repeatedly in the first direction to clean the corresponding groove by each protrusion.

[0092] When the cleaning step is completed, a cleaning detection step can be further performed to detect the cleaning effect, that is, the camera module 5 collects an image of the cleaned groove (which is located in the image collection area), and the control module 8 determines whether the cleaning is in place according to the collected image, and if so, the next step is performed; otherwise, an alarm is issued to remind the operator whether to clean again. Further, if the operator chooses to clean again, the copper bar chain is driven to move reversely by a preset distance and then returns to the position detection step S2.

[0093] Specifically, the control module 8 also stores a cleaning reference image (i.e. an image of the copper bar chain groove with ideal cleaning effect), and the control module 8 compares the image collected by the camera module 5 with the cleaning reference image to determine whether the cleaning is in place.

[0094] Specifically, the control module 8 can be an industrial computer with a human-computer interaction interface, and the camera module 5 is electrically connected to the industrial computer. The camera module 5 can feed back the cleaning effect to the human-computer interaction interface of the industrial computer in the form of images or videos in real time, which is convenient for the manager to view in real time. Specifically, the human-computer interaction interface can display the collected image and the cleaning reference image, and display the difference between the two images and a pop-up window for the operator to choose whether to clean again.

[0095] As shown in Figure 1 The copper bar chain cleaning system also includes an alarm device 7 electrically connected to the control module 8. Specifically, when the control module 8 detects cleaning abnormalities or the protrusion 10221 does not match the groove 2011 in place, the alarm device can be prewarned to remind relevant personnel to implement manual intervention. Specifically, in the control module 8, problem copper bar chain pictures can also be stored in the database, and during the cleaning process, pictures are collected in real time for comparison to determine whether abnormal phenomena (such as copper bar chain cracks, deformation or hair clamping, etc.) occur, and then an abnormal signal is sent to the alarm device 7 to issue an alarm.

[0096] Specifically, a visual recognition model database is constructed in the control module 8, which stores various reference images. Further, the visual recognition model database can also use self-learning and deep learning technology to improve the recognition accuracy of cleaning effect determination and position determination.

[0097] The movement reset step S5: when the movement duration of the scraper reaches the target movement duration or the movement number of the scraper reaches the target movement number, the control module 8 controls the scraper to stop moving in the first direction, drives the cleaning module to move to a preset position, and drives the copper bar chain to move forward by a preset distance.

[0098] Specifically, the target number of movements or the target movement time can be set in advance in the control module, when the movement time or the number of movements of the scraper meets the set condition, the control module controls the cleaning driving part to stop running, and the control module 8 further controls the driving module to drive the cleaning module to move to the preset position, and the control module 8 controls the copper chain to move in the forward direction by the preset distance S0.

[0099] Specifically, the preset distance S0 is less than or equal to the distance S between the two protrusions farthest apart in the extension direction of the scraper, that is, S0 = a * S, where a is an adjustment parameter, and the value of a satisfies 0 < a < 1.

[0100] The judgment step S6: after the cleaning number stored in the copper chain cleaning system is accumulated by 1, it is judged whether the cleaning number is greater than or equal to the set cleaning number; if it is greater than or equal to the set cleaning number, the cleaning number stored in the copper chain cleaning system is cleared; otherwise, return to execute the first moving step.

[0101] Specifically, the set cleaning number can be calculated according to the total length of the copper chain and the length of the scraper, and the set cleaning number satisfies the following relationship:

[0102]

[0103] Wherein, is a floor function, which means rounding x down, M represents the set cleaning number, L represents the total length of the copper chain, S represents the distance between the two protrusions farthest apart in the extension direction of the scraper, and a represents an adjustment parameter, 0 < a < 1.

[0104] The copper chain cleaning method provided by the application can clean the residues in the groove 2011 on the surface of the copper chain 201 of the cutting machine in real time, avoid the feeding problem caused by the groove 2011 being filled with residues, and further ensure the cutting effect of the cutting machine and the quality of the tobacco, prolong the service life of the copper chain 201 of the tobacco factory, and reduce the difficulty of manually cleaning and maintaining the copper chain 201, improve the production efficiency and benefit, provide necessary technical support and protection for the online cleaning and maintenance research of the copper chain 201 of the cutting machine in the tobacco industry, and have strong popularization and application value.
