Description

Technical Field

[0001] This application relates to the field of intelligent manufacturing equipment industry, and in particular to a cleaning system for conveying equipment. Background Technology

[0002] Conveying equipment plays a central role in modern logistics sorting systems, especially in the automated sorting of express parcels. This type of equipment typically uses a conveyor belt as the main transport structure, with sorting components evenly distributed on the belt surface to automatically sort parcels to different sorting slots.

[0003] In related technologies, a typical conveyor cleaning system includes a conveyor belt body, multiple sorting rollers arranged on the conveyor belt, and inclined transfer rollers located below the conveyor belt to drive the sorting rollers to rotate. To address the problem of reduced friction caused by dust accumulation on the sorting rollers due to long-term use, the device includes a cleaning mechanism downstream of the transfer rollers. This cleaning mechanism includes a cleaning bracket fixed to the frame and a cleaning roller rotatably connected to the cleaning bracket. The cleaning roller maintains constant contact with the sorting rollers, and the relative movement between them scrapes away dust from the surface of the sorting rollers, thus maintaining their frictional performance.

[0004] However, existing cleaning systems still have the following shortcomings. The fixed structure in which the sweeping rollers and sorting rollers are always in contact presents the following technical problems in actual operation: Since the sweeping rollers cannot adaptively adjust according to the degree of contamination or wear of the sorting rollers, long-term constant pressure contact not only easily leads to unnecessary wear of the sweeping rollers and sorting rollers, shortening their service life, but also causes ineffective power consumption when the sorting rollers are only lightly contaminated, as continuous contact cleaning is still performed. At the same time, the fixed contact pressure is also difficult to guarantee the effective removal of contamination of different degrees, resulting in insufficient stability of cleaning effect. Summary of the Invention

[0005] This application provides a conveyor cleaning system that solves the problem that the cleaning rollers and sorting rollers are always in contact, which causes unnecessary wear during operation.

[0006] The technical solution adopted in the embodiments of this application is as follows: In a first aspect, embodiments of this application provide a conveyor cleaning system, comprising a frame, on which a conveyor belt body is mounted, the conveying direction of the conveyor belt body being consistent with the length direction of the frame, a first drive for driving the conveyor belt body to operate is provided inside the frame, a sorting component is mounted on the conveyor belt body for sorting objects on the conveyor belt body, a cleaning base is provided downstream of the sorting component, a plurality of cleaning rollers are rotatably connected to the upper surface of the cleaning base for cleaning the sorting component, a fixed base is provided at the bottom of the cleaning base, the fixed base is fixedly connected to the frame, a second drive is fixedly connected to the fixed base, the output shaft of the second drive is fixedly connected to the cleaning base, and the second drive is used to lift the cleaning base so that the cleaning rollers contact the sorting component.

[0007] By adopting the above technical solution, the sweeping rollers are integrated into the sweeping base, and the second drive is used to lift the sweeping base. This allows for control over the contact and separation between the sweeping rollers and the sorting components according to actual needs, significantly extending the service life of both the sweeping and sorting rollers while reducing drive energy consumption. Furthermore, when cleaning operations are required, the second drive can precisely control the lifting height, ensuring the sweeping rollers adhere to the sorting components with appropriate pressure. This ensures effective cleaning while reducing damage caused by excessive pressure, thereby improving the overall reliability and ease of maintenance of the system.

[0008] In one optional implementation, the bottom of the fixed base is detachably connected to a negative pressure box and a dust collection box. The upper surface of the cleaning base has collection holes corresponding to each cleaning roller. The fixed base is funnel-shaped and completely encloses the cleaning base. A centrifugal fan is installed inside the negative pressure box. The inlet of the centrifugal fan is connected to the bottom of the fixed base, and the outlet of the centrifugal fan is connected to the dust collection box.

[0009] By adopting the above technical solution, collection holes are opened on the cleaning base corresponding to each cleaning roller, allowing dust shed during the cleaning process to enter the funnel-shaped fixed base below in a timely manner through the collection holes. The fixed base completely encloses the cleaning base, forming a sealed channel, effectively reducing dust escape into the equipment or environment. The negative pressure generated by the centrifugal fan draws in the dust-laden airflow and transports it to the dust collection box, achieving centralized dust recovery. The detachable connection between the negative pressure box and the dust collection box facilitates regular cleaning and maintenance, ensuring the cleanliness of the working environment, while reducing the re-adhesion of dust onto the sorting rollers, thus achieving a sustained improvement in cleaning effectiveness.

[0010] In one optional implementation, the fixed base is provided with receiving plates on both sides, and the second drive is configured as two, which are respectively fixed to the receiving plates on both sides of the fixed base. The fixed base is provided with a protective cover, which is a telescopic plate structure. The outer plate of the protective cover is detachably connected to the bottom of the cleaning base, and the inner plate of the protective cover is detachably connected to the upper surface of the fixed base. The size of the protective cover is preset to completely cover all collection holes. The receiving plates and the second drive are both located outside the protective cover.

[0011] By adopting the above technical solution, a protective cover is installed to seal the gap between the sweeping base and the fixed base. The protective cover adopts a telescopic plate structure, which can extend and retract with the raising and lowering of the sweeping base, always maintaining complete coverage of the collection hole area and preventing dust from leaking out from the side gaps. The second drive is fixed to the receiving plate and located outside the protective cover, which not only ensures the stable transmission of driving force but also reduces the corrosion of the drive components by dust. The receiving plate enhances the structural strength of the fixed base and provides a stable mounting base for the second drive, ensuring that the negative pressure system can operate efficiently at any working height, thus protecting the drive components from dust contamination and extending the equipment's lifespan.

[0012] In one alternative implementation, the dust collection box is equipped with multi-stage filters.

[0013] By adopting the above technical solution and installing multi-stage filters inside the dust collection box, the incoming dust-laden airflow can be filtered in stages, intercepting dust particles of different sizes in sequence, reducing the direct emission of fine dust into the atmosphere or clogging of subsequent pipes. The multi-stage filtration design improves filtration efficiency, extends the single cleaning cycle, and reduces the load on the centrifugal fan, helping to maintain stable negative pressure suction and ensuring the long-term reliability of the dust collection system.

[0014] In one optional implementation, the sorting assembly includes sorting rollers, a transfer frame, and transfer rollers. Several sorting rollers are rotatably connected to the conveyor belt body. The transfer frame is fixedly connected to the frame, and the transfer rollers are rotatably connected to the transfer frame. The transfer frame and transfer rollers are arranged in two sets, located on opposite sides of the conveyor belt body in the conveying direction. The transfer rollers are in direct contact with the sorting rollers. The transfer rollers are designed to be inclined to drive the sorting rollers to rotate, thereby sorting items on the conveyor belt body.

[0015] By employing the above technical solution, the inclined transfer rollers make frictional contact with the sorting rollers, driving the sorting rollers to rotate laterally, thereby applying lateral force to the packages on the conveyor belt to achieve sorting. Two sets of transfer rollers are symmetrically arranged on both sides of the conveyor belt and can be controlled independently to achieve bidirectional sorting. This structure is compact and reliable, utilizing friction to drive the process without an additional power source, efficiently completing the automatic sorting of packages. It ensures that the cleaning rollers can accurately act on the sorting roller surfaces that require cleaning, thus improving the targeting and effectiveness of cleaning.

[0016] In one optional implementation, a central controller is provided on the frame, and an infrared camera is provided in the frame corresponding to the cleaning base. The infrared camera is electrically connected to the central controller. Each cleaning roller is provided with an independent third drive, which is used to drive the cleaning roller to rotate actively. Both the second drive and the third drive are electrically connected to the central controller. The central controller can determine the contamination status based on the characteristics such as the surface color and light reflection characteristics of the sorting roller transmitted by the infrared camera, so as to drive the cleaning base to rise and the cleaning roller to rotate actively.

[0017] By adopting the above technical solution, an infrared camera monitors the contamination status of the sorting roller surface in real time. The central controller determines the degree of contamination based on image features and controls the second drive to lift the cleaning base so that the cleaning roller contacts it. Simultaneously, the third drive is activated to make the cleaning roller actively rotate for cleaning. This reduces energy consumption and wear caused by blindly performing periodic cleaning. Cleaning is only initiated when the contamination reaches a certain threshold, thereby maximizing the utilization of equipment resources. The independent third drive enables the cleaning roller to rotate actively, enhancing cleaning power. Especially for stubborn stains, the effect can be optimized by adjusting the speed and direction. Through the combination of visual perception and automatic control, precise triggering and adaptive adjustment of cleaning operations are achieved, improving cleaning efficiency.

[0018] In one optional implementation, the surface of the cleaning base is provided with a plurality of micro nozzles, which can spray cleaning agent. A micro filter screen is detachably connected to the nozzle head of the micro nozzle. The micro nozzles face the cleaning roller. The cleaning roller has a built-in friction sensor. The friction sensor, the micro nozzles and the central controller are electrically connected. The central controller can determine the degree of pollution based on the friction data transmitted by the friction sensor. When the friction coefficient is low, it drives the micro nozzles to spray cleaning agent.

[0019] By adopting the above technical solution, the friction sensor detects the friction coefficient between the sweeping roller and the sorting roller in real time. When the detected friction coefficient is lower than a set threshold, the central controller activates the micro-nozzle to spray an appropriate amount of detergent to dissolve and soften the dirt, which is then removed by the rotation of the sweeping roller. A micro-filter at the micro-nozzle head prevents impurities in the detergent from clogging the nozzle, ensuring uniform spraying. The chemical assistance significantly improves the cleaning ability for complex contaminants. Simultaneously, feedback from the friction sensor makes the use of detergent more precise, reducing waste or secondary pollution caused by overspraying. This achieves a fusion of physical and chemical cleaning methods, and dynamic adjustments based on real-time friction data improve the system's applicability.

[0020] In one optional implementation, the cleaning roller has a multi-layer structure, consisting of, from the inside out, a roller base layer, a heating wire layer uniformly embedded in the surface of the roller base layer, an electrical insulation layer covering the heating wire layer, and a working surface layer. The heating wire is electrically connected to a central controller, the working surface layer has a built-in humidity sensor, the humidity sensor is electrically connected to the central controller, and the electrical insulation layer is made of an insulating and thermally conductive material.

[0021] By adopting the above technical solution, a multi-layer composite design is used, incorporating a built-in heating wire and humidity sensor. The humidity sensor monitors the humidity of the roller surface or the environment in real time. When excessive humidity is detected, leading to increased dirt adhesion, the central controller activates the heating wire. Heat is rapidly transferred to the working surface layer through a highly thermally conductive insulation layer, causing a moderate increase in the roller surface temperature. This accelerates moisture evaporation and reduces dirt adhesion, thereby restoring the cleaning effect. The working surface layer, which directly contacts the dirt, must possess both wear resistance and thermal conductivity. The electrical insulation layer ensures electrical safety without affecting heat transfer. Through active heating, the system can adapt to varying working conditions, achieving a stable cleaning performance.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating the cleaning rollers into a liftable cleaning base and controlling their contact and separation from the sorting components via a second drive, an on-demand cleaning mode is achieved. Compared to a fixed contact structure, this solution significantly reduces unnecessary friction between the cleaning rollers and the sorting rollers, extending their service life and reducing energy waste caused by continuous operation. When cleaning is required, the second drive precisely controls the lifting height, ensuring the cleaning rollers engage with appropriate pressure, guaranteeing cleaning effectiveness while reducing damage caused by excessive pressure, effectively improving the overall system reliability and ease of maintenance. 2. Collection holes are made on each cleaning roller on the cleaning base, forming an integrated dust collection channel with a funnel-shaped fixed base, negative pressure box, and dust collection box. Dust shed during cleaning enters the sealed channel through the collection holes and is then drawn into the dust collection box by a centrifugal fan for centralized collection, effectively reducing dust escape and secondary pollution. The detachable negative pressure box and dust collection box facilitate cleaning and maintenance. Multi-stage filters intercept dust-laden airflow in stages, reducing fan load and maintaining stable negative pressure, significantly improving cleaning durability and the cleanliness of the working environment. 3. An intelligent adaptive cleaning system is constructed by integrating a central controller, infrared camera, friction sensor, and humidity sensor. The infrared camera monitors the contamination level of the sorting rollers in real time and precisely triggers cleaning actions; the friction sensor detects changes in the coefficient of friction and activates micro-nozzles to spray cleaning agent as needed to enhance the removal of stubborn stains; the humidity sensor automatically activates the built-in heating wire when it detects humid conditions, accelerating moisture evaporation and reducing dirt adhesion. Through multi-sensor fusion and collaborative control, precise triggering of cleaning operations, multi-mode switching, and all-weather adaptability are achieved, significantly improving cleaning efficiency and intelligence under complex working conditions.

Detailed Implementation

[0028] The present application will be further described in detail below with reference to all the accompanying drawings in the embodiments of the present application.

[0029] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after the connection. It should be understood that when component A is fixedly connected to component C via component B, changes in the relative positional relationship due to deformation of components A, B, and C are permissible. The integrated structure obtained by the two components through a one-piece molding process means that during the formation of one of the two components, that component is connected to the other component, without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to connect the two components.

[0030] The directional terms mentioned in the embodiments of this application, such as "upper", "lower", "side", etc., are only for reference to the direction of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0031] The term "multiple" refers to at least two. The term "more than" includes the stated number. The term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0032] This application discloses a cleaning system for conveying equipment.

[0033] Reference Figure 1 A conveying equipment cleaning system includes a frame 1 as the overall installation base. The frame 1 is a steel frame structure used to support and accommodate the various components of the entire system. A central controller is installed on the frame 1.

[0034] A conveyor belt body 2 is installed on the frame 1. The conveying direction of the conveyor belt body 2 is consistent with the length direction of the frame 1, and it is used to carry and transport items such as express parcels.

[0035] A first drive 14 is installed inside the frame 1. The first drive 14 specifically includes components such as a drive motor, a reducer, and a transmission roller. It is connected to the conveyor belt body 2 via a chain to provide it with stable conveying power.

[0036] Reference Figure 1 and Figure 2 A sorting assembly is provided on the conveyor belt body 2. The sorting assembly includes multiple sorting rollers 3, a transfer frame 6, and transfer rollers 7.

[0037] Reference Figure 1 The sorting roller 3 is uniformly rotated and connected to the conveyor belt body 2, and the rotation axis of the sorting roller 3 is perpendicular to the conveying direction of the conveyor belt body 2.

[0038] Reference Figure 1 and Figure 2 The transfer frame 6 is fixedly connected to the frame 1, and its position corresponds to the area where sorting operations need to be performed. The transfer rollers 7 are rotatably connected to the transfer frame 6, and the transfer frame 6 and the transfer rollers 7 are set in two sets, located on both sides of the conveyor belt body 2 in the conveying direction.

[0039] The transfer roller 7 maintains direct contact with the sorting roller 3, and the axis of rotation of the transfer roller 7 is designed to be inclined relative to the horizontal plane. When the transfer roller 7 is driven to rotate by an external power, it drives the sorting roller 3 to rotate through friction. Because the transfer roller 7 is inclined, the direction in which it drives the sorting roller 3 to rotate forms an angle with the conveyor belt conveying direction, thereby applying a lateral thrust to the packages on the conveyor belt, causing them to slide out from the side of the conveyor belt and enter the designated sorting slot, thus realizing automatic sorting.

[0040] Reference Figure 2 and Figure 4 A cleaning device is located downstream of the sorting assembly along the conveying direction, downstream of the transfer roller 7. This cleaning device includes a cleaning base 10, which is situated entirely within the specified location. Figure 1 Below the conveyor belt body 2.

[0041] Reference Figure 3 and Figure 4 Several cleaning rollers 8 are rotatably connected to the upper surface of the cleaning base 10. These cleaning rollers 8 are used to interact with the upper surface, as shown in the reference. Figure 1 The sorting rollers 3 come into contact with and are cleaned.

[0042] Several micro-nozzles are provided on the surface of the cleaning base 10. These micro-nozzles are positioned towards the cleaning roller 8 and are used to spray cleaning agent.

[0043] Reference Figure 4 The cleaning base 10 has several brushes along its edge.

[0044] The nozzle of the micro-nozzle is detachably connected to a micro-filter screen to filter impurities in the cleaning agent and prevent clogging.

[0045] Reference Figure 3 The cleaning roller 8 adopts a multi-layer composite structure, consisting of a roller base layer, an electric heating wire layer uniformly embedded in the surface of the roller base layer, an electrical insulation layer covering the electric heating wire layer, and an outermost working surface layer from the inside out.

[0046] The heating wire is electrically connected to the central controller to generate heat. A humidity sensor, also electrically connected to the central controller, is built into the working surface to monitor the humidity on the roller surface or in the environment in real time.

[0047] The electrical insulation layer is made of thermally conductive ceramic. When the humidity sensor detects excessive humidity and determines that dirt adhesion is enhanced, the central controller activates the heating wire. Heat is rapidly transferred to the working surface layer through the highly thermally conductive electrical insulation layer, causing the surface temperature of the sweeping roller 8 to rise moderately. This accelerates the evaporation of moisture in the contact area and reduces the adhesion of dirt, allowing the sweeping roller 8 to more effectively remove dirt and restore cleaning performance.

[0048] Reference Figure 1 and Figure 3 A friction sensor is built into the cleaning roller 8 to sense the friction force when the cleaning roller 8 comes into contact with the sorting roller 3 in real time.

[0049] Both the friction sensor and the micro-nozzle are electrically connected to the central controller. The central controller can determine the degree of contamination based on the friction data transmitted by the friction sensor. When the friction coefficient is detected to be lower than a preset threshold, it indicates that there is oil or sticky dirt causing slippage. At this time, the central controller drives the micro-nozzle to start and spray an appropriate amount of cleaning agent onto the surface of the sweeping roller 8 or sorting roller 3 to dissolve or soften the dirt, which is then peeled off by the rotation of the sweeping roller 8.

[0050] Reference Figure 1 and Figure 4 A fixed base 11 is provided below the cleaning base 10. The fixed base 11 is fixedly connected to the frame 1 and serves to support and position the machine. A cavity is provided on the upper surface of the fixed base 11.

[0051] Reference Figure 4 A second drive 15, which is a cylinder, is fixedly connected to the fixed base 11. The output shaft of the second drive 15 is fixedly connected to the cleaning base 10. Through the extension and retraction of the second drive 15, the cleaning base 10 can be driven to move up and down relative to the fixed base 11.

[0052] The fixed base 11 has support plates 13 on both sides. There are two second drives 15, which are fixedly installed on the support plates 13 on both sides of the fixed base 11. This symmetrical arrangement ensures the balanced force and stability of the cleaning base 10 when it is raised and lowered.

[0053] Reference Figure 3 and Figure 4 A protective cover 12 is also provided on the fixed base 11. The protective cover 12 adopts a telescopic plate structure. The outer plate of the protective cover 12 is detachably connected to the bottom of the cleaning base 10, and the inner plate of the protective cover 12 is detachably connected to the upper surface of the fixed base 11. The telescopic stroke of the protective cover 12 matches the lifting stroke of the cleaning base 10, and its size is preset to completely cover the area where all collection holes 9 are located.

[0054] Reference Figure 4 The receiving plate 13 and the second drive 15 are both located outside the protective cover 12. This structure allows the protective cover 12 to extend and retract synchronously with the lifting and lowering of the cleaning base 10, always dynamically sealing the gap between the cleaning base 10 and the fixed base 11, preventing dust from escaping from the side gaps. At the same time, since the second drive 15 is located outside the protective cover 12, it avoids direct contact with the dust-laden airflow, reducing dust corrosion of the drive components and extending the equipment's lifespan.

[0055] Reference Figure 3 and Figure 4 When cleaning is required, the second drive 15 extends, lifting the sweeping base 10, causing the sweeping roller 8 to move upward and contact the lower edge of the sorting roller 3; when cleaning is not required, the second drive 15 retracts, causing the sweeping roller 8 to contact the lower edge of the sorting roller 3. Figure 1 The sorting roller 3 separates. This liftable structure allows the sweeping roller 8 to contact or separate from the sorting component as needed, avoiding unnecessary continuous friction and thus significantly extending the service life of the sweeping roller 8. (Refer to...) Figure 1 This extends the lifespan of the sorting rollers 3 and reduces unnecessary drive energy consumption.

[0056] Reference Figure 3 and Figure 4 The second drive 15 has a controllable stroke, enabling precise control of the sweeping rollers 8, as shown in the reference. Figure 1 The contact pressure of the sorting roller 3 ensures both cleaning effectiveness and prevents damage to the roller due to excessive pressure.

[0057] Reference Figure 3 and Figure 4 The bottom of the fixed base 11 is detachably connected to, as shown in the reference. Figure 1 The cleaning base 10 has a negative pressure box 4 and a dust collection box 5. The upper surface of the cleaning base 10 is provided with collection holes 9 corresponding to the position of each cleaning roller 8. These collection holes 9 penetrate the cleaning base 10 and are used to guide the dust detached by the cleaning roller 8 downward.

[0058] Reference Figure 4The fixed base 11 is designed in the shape of a funnel, and its size is set so that the cavity completely covers the cleaning base 10, so that a relatively sealed cavity is formed between the cleaning base 10 and the fixed base 11.

[0059] Reference Figure 1 and Figure 4 A centrifugal fan is installed inside the negative pressure box 4. The inlet of the centrifugal fan is connected to the bottom of the fixed base 11 through a pipe, and the outlet of the centrifugal fan is connected to the dust collection box 5.

[0060] Reference Figure 3 and Figure 4 When the centrifugal fan starts, a negative pressure is generated inside the fixed base 11. During the cleaning process, [refer to...] Figure 1 The dust detached from the sorting roller 3 is sucked into the funnel-shaped fixed base 11 through the collection hole 9 on the cleaning base 10, and then enters with the airflow, as shown in the reference. Figure 1 The dust collection box 5 is used for settling and collection.

[0061] Reference Figure 1 The detachable negative pressure box 4 and dust collection box 5 facilitate regular cleaning and maintenance, ensuring the cleanliness of the working environment and reducing the re-adhesion of dust on the sorting rollers 3, thus improving the durability of the cleaning effect.

[0062] The dust collection box 5 is equipped with a multi-stage filter. The multi-stage filter includes three stages: a pre-filter to intercept large particles, a medium-efficiency filter to intercept medium-sized dust particles, and a high-efficiency filter to intercept fine dust particles.

[0063] After the dust-laden airflow enters the dust collection box 5, it passes through various levels of filters for graded filtration. Dust particles of different sizes are intercepted separately, effectively reducing the direct emission of fine dust into the atmosphere or clogging of subsequent pipelines.

[0064] Reference Figure 1 and Figure 4 An infrared camera is installed in the frame 1 at the position corresponding to the cleaning base 10. The infrared camera is electrically connected to the central controller, and its lens is aimed at the sorting roller 3 area to collect image information of the surface of the sorting roller 3 in real time.

[0065] Reference Figure 3 Each sweeping roller 8 is equipped with an independent third drive 16, which uses a micro motor to drive the sweeping roller 8 to rotate actively.

[0066] Reference Figure 3 and Figure 4 Both the second drive 15 and the third drive 16 are electrically connected to the central controller. The central controller has a pre-set image processing algorithm that can process images transmitted from the infrared camera, referring to… Figure 1The surface color and light reflection characteristics of sorting roller 3 are analyzed and judged, with reference to... Figure 1 The degree of contamination of sorting roller 3.

[0067] Reference Figure 3 and Figure 4 When the pollution level reaches a preset threshold and cleaning is required, the central controller controls the second drive 15 to lift the sweeping base 10 so that the sweeping rollers 8 are aligned with the target area. Figure 1 When the sorting roller 3 comes into contact, the third drive 16 is activated, causing the cleaning roller 8 to rotate actively for cleaning.

[0068] The implementation principle of a conveying equipment cleaning system in this application embodiment is as follows: When the system is running, the central controller monitors the degree of contamination on the surface of the sorting roller 3 in real time through an infrared camera. At the same time, the friction sensor and humidity sensor respectively sense the friction coefficient and ambient humidity when the cleaning roller 8 contacts the sorting roller 3.

[0069] When the pollution level reaches the preset threshold, the central controller instructs the second drive 15 to lift the cleaning base 10, so that the cleaning roller 8 fits into the sorting roller 3, and starts the third drive 16 to make the cleaning roller 8 rotate actively for cleaning.

[0070] If the friction sensor indicates that the friction coefficient is too low, it means that there are stubborn contaminants such as oil stains. In this case, the micro nozzle will be activated to spray cleaning agent to help dissolve the contaminants. If the humidity sensor detects that the humidity is too high, the built-in heating wire will be activated to heat the roller surface through the thermally conductive insulation layer, thereby accelerating the evaporation of moisture and reducing the adhesion of dirt.

[0071] During the cleaning process, the centrifugal fan generates negative pressure within the fixed base 11. The detached dust is drawn into the funnel-shaped fixed base 11 through the collection holes 9 on the cleaning base 10, and then enters the dust collection box 5 where it undergoes graded settling through multi-stage filters. The entire system achieves coordinated operation of visual inspection, physical scraping, chemical assistance, thermal drying, and negative pressure dust collection. It can automatically switch cleaning modes according to actual working conditions to ensure that the sorting rollers 3 are always in optimal working condition.

That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.
