Description

Technical Field

[0001] This invention relates to the field of material handling equipment technology, and in particular to a surface material stripping and extraction device, method and system. Background Technology

[0002] In the fields of powder material production and chemical processing, it is often necessary to peel off and recycle materials adhering to the inner wall of containers. In the existing technology, such operations are usually carried out by manual scraping or simple mechanical scrapers combined with independent dust collection.

[0003] However, existing processing methods have the following technical problems: On the one hand, the size of the mechanical scraping structure is usually fixed, making it difficult to adapt to containers with different inner diameters, resulting in poor equipment versatility and frequent tooling changes when changing container specifications; on the other hand, there is often a spatial distance between the stripping operation point and the material collection point, and the material is very easy to fly and escape secondary at the moment it is stripped from the inner wall, which not only causes material waste and environmental pollution, but also increases the difficulty of subsequent cleaning. Summary of the Invention

[0004] The main objective of this invention is to propose a surface material peeling and extraction device, method, and system, which aims to achieve radial adaptive adhesion of the peeling end to the inner wall of the container and spatial coupling between peeling and in-situ suction.

[0006] Preferably, the stripping actuator further includes a radial adjustment drive mechanism and a guide assembly; The radial adjustment drive mechanism is configured to drive the peeling end to move along the guide assembly to adjust the radial extension length of the peeling end.

[0007] Preferably, the peeling end includes a peeling blade; The peeling blade is mounted on the sliding end of the guide assembly via a blade holder. The cutting edge of the peeling blade is inclined toward the tangential direction of the inner wall of the container so as to form a scraping contact when rotating. The radial adjustment drive mechanism includes a telescopic cylinder, the cylinder body of which is fixed to the center hub of the stripping actuator, and the piston rod of which is connected to the blade holder.

[0008] Preferably, the suction assembly further includes a follower connection structure; The suction port is fixed to the rotation center or side of the peeling actuator through the follower connection structure, so as to keep the relative position of the suction port and the peeling end constant during the lifting and rotation of the peeling actuator.

[0009] Preferably, the stripping actuator further includes a plurality of guide vanes arranged radially around the central hub; One end of each of the guide vanes is connected to the outer circumferential surface of the central hub, and the other end extends to the inner wall of the outer frame near the stripping actuator. The guide vanes have a curved shape and are configured to gather the peeled-off attached material towards the center of the suction port when the peeling actuator rotates.

[0010] Preferably, the frame is equipped with a lifting drive mechanism; The rotary drive mechanism, the stripping actuator, and the suction assembly are all installed at the output end of the lifting drive mechanism, so as to drive the whole assembly to lift and lower through the lifting drive mechanism to adapt to containers of different depths.

[0011] Preferably, the top of the stripping actuator is provided with a dust cover; The material suction assembly also includes a negative pressure generator and a material storage bin; The suction port is connected to the input end of the negative pressure generator through the suction pipe, and the output end of the negative pressure generator is connected to the storage bin. The dust cover, the suction port, the suction pipe, the negative pressure generator and the storage bin form a closed negative pressure air path from the stripping point to the storage bin.

[0012] Preferably, it also includes a conveying mechanism and a pressure monitoring element; The conveying mechanism is located at the bottom of the frame and is configured to carry and convey the container to the working position below the stripping actuator; The pressure monitoring device is installed on the inner wall of the conveying mechanism and is configured to monitor the pressure between the container and the conveying mechanism in real time, and feed the pressure signal back to the control system to adjust the running length of the conveying mechanism.

[0013] Furthermore, the present invention also provides a method for peeling and removing surface material, comprising: Place the peeling actuator into the container and adjust the radial extension length of the peeling end of the peeling actuator so that the peeling end fits against the inner wall of the container. Drive the peeling end to rotate to peel off the material adhering to the inner wall of the container; During the peeling process at the peeling end, the attached material that has been peeled off is sucked up in situ through a suction port that is adjacent to the peeling actuator.

The control cabinet is communicatively connected to the surface material stripping and removal equipment, and upstream and downstream conveyor lines are used to transport the containers.

[0015] The technical solution provided by this invention fundamentally solves the two major technical problems of poor versatility and dust dispersion in traditional equipment by coordinating the radial telescopic design of the peeling actuator with the follow-up proximity setting of the suction port. Specifically, the radially adjustable peeling end breaks the limitations of fixed-size tooling, allowing a single device to seamlessly adapt to containers of various inner diameters, significantly reducing equipment investment and replacement costs. The constant spatial proximity between the suction port and the peeling end, combined with the centripetal convergence effect of the rotating guide vanes, highly couples the mechanical peeling action and the pneumatic collection action in microscopic spacetime, so that the material is captured by negative pressure the moment it detaches from the inner wall, completely cutting off the dust diffusion path. This improves the material recovery rate while meeting stringent environmental protection and occupational health requirements. Attached Figure Description

[0023] This invention provides a surface material peeling and extraction device. Figures 1 to 2 This is an embodiment of the surface material stripping and extraction device provided by the present invention.

[0024] Please refer to the following: Figures 1 to 2The surface material peeling and removal device 100 includes a frame 1, a rotary drive mechanism 2, a peeling actuator 3, and a suction assembly 4. The rotary drive mechanism 2 is mounted on the frame 1. The peeling actuator 3 is connected to the output end of the rotary drive mechanism 2. The peeling actuator 3 has a peeling end that can extend and retract radially. The peeling end is configured to rotate under the drive of the rotary drive mechanism 2 to peel off the attached material from the inner wall of the container 9. The suction assembly 4 includes a suction port 41. The suction port 41 is arranged adjacent to the peeling actuator 3 and is configured to perform in-situ suction of the peeled attached material when the peeling end peels off the attached material.

[0025] The rotary drive mechanism 2 is mounted on the frame 1, and the peeling actuator 3 is connected to the output end of the rotary drive mechanism 2. The peeling actuator 3 has a radially extendable peeling end, which is configured to rotate under the drive of the rotary drive mechanism 2 to peel off the attached material from the inner wall of the container 9. The radial extension of the peeling end is a functional limitation, the core of which is to enable the working radius of the peeling actuator 3 to be dynamically adjustable, thereby adapting to containers 9 with different inner diameters. In actual operation, when facing a container 9 with a larger inner diameter, the peeling end extends outward to increase the working radius; when facing a container 9 with a smaller inner diameter, the peeling end retracts inward to reduce the working radius. This radial adaptive mechanism allows a single device to be compatible with containers 9 of various sizes without changing tooling, fundamentally solving the technical problem of poor versatility of traditional fixed-size peeling devices. It should be understood that the specific mechanical structure for realizing this radial extension function can take many forms, such as linear drive combined with guide slider, linkage mechanism, or hydraulic telescopic rod, etc., as long as it can achieve continuous or graded adjustment of the radial position of the peeling end, it falls within the protection scope of this embodiment.

[0026] The suction assembly 4 includes a suction port 41, which is positioned adjacent to the peeling actuator 3. It is configured to perform in-situ suction of the peeled material when it is peeled off at the peeling end. In this embodiment, "adjacent positioning" means that the suction port 41 and the peeling actuator 3 maintain synchronous movement or relative stillness in space. Specifically, regardless of the lifting height or rotation phase of the peeling actuator 3, the suction port 41 always moves closely following the peeling end or maintains a constant close spatial relationship with it. This design ensures that the peeling point is the suction point, allowing the attached material to be immediately captured by negative pressure the moment it detaches from the inner wall of the container 9, preventing secondary scattering and escape of the material under gravity or centrifugal force. It should be noted that the adjacent positioning is not limited to rigidly fixing the suction port 41 directly to the peeling actuator 3. An independent linkage mechanism can also be used to maintain a preset following trajectory between the suction port 41 and the peeling end, as long as the relative position of the two during operation meets the requirements for in-situ, immediate suction.

[0027] Through the aforementioned architecture, the radial expansion and contraction characteristics of the peeling end enable the equipment to be widely adaptable to containers 9 of various sizes. Simultaneously, the close proximity and follow-up arrangement of the suction port 41 and the peeling actuator 3 highly couples the mechanical peeling action and the pneumatic collection action in a microscopic spatiotemporal manner. This synergistic effect not only significantly improves the equipment's process flexibility and production efficiency but also cuts off the dust diffusion path at the source, effectively solving the technical challenges of poor versatility and environmental pollution inherent in existing technologies.

[0028] Through the radial telescopic design of the peeling end, the device can dynamically adjust the working radius to adapt to containers 9 with different inner diameters, solving the problem that a single device cannot be compatible with containers 9 of multiple specifications. At the same time, by setting the suction port 41 and the peeling execution member 3 adjacent to each other, the suction port 41 always moves closely with the peeling operation point, and the material is captured immediately when it leaves the inner wall, thus suppressing the diffusion and dispersion of dust from the source.

[0029] Therefore, in the technical solution provided by the present invention, the rotary drive mechanism 2 is installed on the frame 1, the peeling actuator 3 is connected to the output end of the rotary drive mechanism 2, the peeling actuator 3 has a peeling end that can be extended and retracted radially, the peeling end is configured to rotate under the drive of the rotary drive mechanism 2 to peel off the attached material on the inner wall of the container 9, and the suction assembly 4 includes a suction port 41, the suction port 41 is arranged adjacent to the peeling actuator 3, and is configured to perform in-situ suction of the peeled attached material when the peeling end peels off the attached material.

[0030] In an embodiment of the present invention, the peeling actuator 3 further includes a radial adjustment drive mechanism and a guide assembly; the radial adjustment drive mechanism is configured to drive the peeling end to move along the guide assembly to adjust the radial extension length of the peeling end.

[0031] Specifically, the guide assembly provides a precise linear constraint trajectory for the radial movement of the peeling end, effectively withstanding the tangential reaction force and radial impact force generated during the peeling operation, preventing the peeling end from deflecting or jamming under stress. This guiding mechanism ensures the smoothness and repeatability of the radial adjustment process, allowing the peeling end to maintain its preset working posture against the inner wall of container 9, thereby guaranteeing a uniform peeling effect. It should be understood that the specific form of the guide assembly is not limited to the linear guide rail shown in the figure; it can also be a guide rod slider mechanism, a dovetail groove structure, or other mechanical components that can provide single-degree-of-freedom linear motion constraints, as long as they can achieve stable radial guidance of the peeling end.

[0032] Furthermore, the peeling end includes a peeling blade; the peeling blade is mounted on the sliding end of the guide assembly via a blade holder, and the cutting edge of the peeling blade is inclined toward the tangential direction of the inner wall of the container 9 to form a scraping contact during rotation; the radial adjustment drive mechanism includes a telescopic cylinder, the cylinder body of the telescopic cylinder is fixed to the central hub 31 of the peeling actuator 3, and the piston rod of the telescopic cylinder is connected to the blade holder.

[0033] The mechanical advantage of the tangentially inclined setting is that when the peeling actuator 3 rotates at high speed, the cutting edge of the peeling blade does not act on the attached material in a vertical impact manner, but rather cuts into the material layer at a progressive shearing angle. Compared to vertical impact, shearing scraping can significantly reduce the instantaneous impact load, reduce the risk of mechanical damage to the inner wall of container 9, and at the same time, make the cutting force evenly distributed along the cutting edge direction, avoiding stress concentration that could lead to blade breakage or premature wear. In addition, the shearing action can peel off the attached material in a more continuous sheet or strip form, rather than pulverizing it into fine particles. This physically reduces the difficulty of subsequent negative pressure suction and improves the overall collection efficiency.

[0034] In terms of the driving method, the radial adjustment drive mechanism includes a telescopic cylinder. The cylinder body of the telescopic cylinder is fixed to the central hub 31 of the peeling actuator 3, and the piston rod of the telescopic cylinder is connected to the blade holder. This embodiment selects a telescopic cylinder instead of a motor screw module as the radial drive source based on comprehensive considerations of specific working conditions. First, the dust concentration in the peeling operation environment inside the container 9 is extremely high. The precision threaded pair of the motor screw module is easily invaded by fine powder, leading to jamming or loss of precision. The telescopic cylinder, with its sealed piston structure, naturally possesses excellent dustproof and anti-pollution capabilities, long maintenance cycles, and high reliability. Second, the peeling blade generates a large radial impact load the moment it contacts the inner wall of the container 9. The compressed air inside the cylinder has natural elastic buffering characteristics, which can effectively absorb impact energy and protect the drive mechanism from rigid damage. Under the same impact, the motor screw is prone to thread deformation or coupling failure. Furthermore, the cylinder has a fast telescopic response speed, which can quickly complete the adjustment and locking of the radial position when changing to different specifications of the container 9, significantly shortening the equipment changeover preparation time and improving the overall cycle efficiency of the production line. Of course, in special application scenarios where the adjustment accuracy is extremely high and the working environment is relatively clean, alternative solutions such as stepper motors combined with ball screws or linear motors can be used to realize the function of radial adjustment drive mechanism. However, for the high dust and strong impact working conditions targeted in this embodiment, telescopic cylinder is the optimal choice that balances durability, safety and efficiency.

[0035] In an embodiment of the present invention, the suction assembly 4 further includes a follower connection structure; the suction port 41 is fixed to the rotation center or side of the peeling actuator 3 through the follower connection structure, so as to keep the relative position of the suction port 41 and the peeling end constant during the lifting and rotation of the peeling actuator 3.

[0036] Specifically, the follower connection structure rigidly couples the suction port 41 to the motion system of the peeling actuator 3, making it an inseparable functional module of the peeling actuator 3. Regardless of the lifting height of the peeling actuator 3 to adapt to containers 9 of different depths, and regardless of its rotation phase angle, the suction port 41 always maintains a preset spatial distance and orientation relationship with the peeling end. This constant relative positional relationship is the physical basis for achieving efficient in-situ suction. It ensures that the negative pressure capture area always accurately covers the peeling operation point, eliminating the suction attenuation blind zone or capture lag caused by the relative displacement of the two. It should be understood that the specific implementation of the follower connection structure is not limited to the central shaft sleeve method shown in the figure. It can also be a lateral cantilever bracket, flange bolt connection, or other mechanical connection that can synchronously drive the suction port 41 and the peeling actuator 3. As long as the relative posture of the two remains unchanged in three-dimensional space, it falls within the protection scope of this embodiment.

[0037] Furthermore, the peeling actuator 3 also includes a plurality of guide vanes 32 arranged radially around the central hub 31; one end of each guide vane 32 is connected to the outer circumferential surface of the central hub 31, and the other end extends to the inner wall of the outer frame 33 of the peeling actuator 3; the guide vane 32 has a curved surface shape and is configured to gather the peeled attached material toward the center to the suction port 41 when the peeling actuator 3 rotates.

[0038] The above design is an active enhancement of passive material suction relying solely on negative pressure. From the perspective of fluid dynamics and particle dynamics, when the stripping actuator 3 rotates at high speed, the curved guide vanes 32 not only act as mechanical pushers to directly move the material scattered at the bottom of the container 9 towards the center, but more importantly, their specific curved contours create a low-pressure zone pointing towards the center of rotation on the windward side of the vanes during rotation, thereby generating a continuous centripetal airflow. This centripetal airflow, combined with the mechanical thrust, forms a composite centripetal transport mechanism that can overcome the inertia of the material itself and the frictional resistance of the container 9 wall, actively converging the stripping material originally dispersed in the edge area to the vicinity of the suction port 41 located in the center.

[0039] In contrast, without the structure of the guide vanes 32, relying solely on the negative pressure of the central suction port 41, the attached material is easily thrown towards the inner wall edge of the container 9 or even splashed upwards under the action of centrifugal force when the peeling actuator 3 rotates. This results in a large amount of material escaping from the effective negative pressure capture area, causing a significant decrease in collection efficiency and secondary dust pollution. In this embodiment, the curved guiding effect of the guide vanes 32 cleverly converts the rotational kinetic energy into a centripetal transport force that is conducive to material collection, changing "centrifugal diffusion" to "centripetal aggregation," significantly improving the control capability of the gas-solid two-phase flow and the material recovery rate. It should be noted that the number, radius of curvature, and installation angle of the guide vanes 32 can be optimized and adjusted according to the material characteristics (such as particle size, density, viscosity) and rotation speed range. For example, a larger curvature can be used for lightweight and easily airborne powders to increase the aerodynamic aggregation effect, while the number of vanes can be increased for heavy particles to enhance the mechanical pushing effect. These modifications are all within the protection scope of this invention.

[0040] In the technical solution of the present invention, the frame 1 is provided with a lifting drive mechanism 5; the rotary drive mechanism 2, the stripping actuator 3 and the suction assembly 4 are integrally installed at the output end of the lifting drive mechanism 5, so as to drive the whole to lift and lower through the lifting drive mechanism 5 to adapt to the containers 9 of different depths.

[0041] Specifically, the lifting drive mechanism 5 provides the device with vertical positional adjustment freedom, enabling it to flexibly adjust the initial working height and working stroke of the stripping actuator 3 and the suction assembly 4 according to the actual depth of the container 9. When processing deep-cavity containers 9, the lifting drive mechanism 5 can lower the core working module to the bottom area of ​​the container 9 to begin operation, and gradually raise it as the stripping process progresses; when processing shallow tray-type containers 9, the lifting stroke can be shortened to avoid ineffective empty travel. This adaptive capability in the vertical dimension, combined with the radial extension capability of the stripping end in the aforementioned embodiment, constitutes a two-dimensional compatible system for the geometric dimensions of the container 9, significantly expanding the applicability and process flexibility of the equipment. It should be understood that the specific implementation of the lifting drive mechanism 5 is not limited to the electric slide rail module shown in the figure, but can also be a hydraulic cylinder, a gear and rack transmission chain, a winch, or other drive components that can provide stable linear lifting motion, as long as they can achieve the controllable lifting function of the entire working module, they all fall within the protection scope of this embodiment.

[0042] Furthermore, the top of the stripping actuator 3 is provided with a dust cover 6; the suction assembly 4 also includes a negative pressure generator and a storage bin 42; the suction port 41 is connected to the input end of the negative pressure generator through a suction pipe, and the output end of the negative pressure generator is connected to the storage bin 42. The dust cover 6, the suction port 41, the suction pipe, the negative pressure generator and the storage bin 42 form a closed negative pressure air path from the stripping point to the storage bin 42.

[0043] The core design of this closed negative pressure airway lies in constructing a material transport channel that is physically isolated from the external environment. Specifically, the dust cover 6, acting as a barrier at the beginning of the airway, covers the opening of container 9 or extends into the interior of container 9 during operation, effectively blocking external airflow from interfering with the stripping area and preventing internal dust from spreading outward. The negative pressure generator continuously draws in, maintaining a slightly negative pressure state below atmospheric pressure throughout the airway. This means that even if there are tiny gaps at the airway connections, the airflow direction is always from the outside in, rather than from the inside out, thus fundamentally eliminating the possibility of dust spillage. After being captured at the suction port 41, the stripped material is transported in a sealed manner through the suction pipe to the storage bin 42 for temporary storage, without contacting the workshop environment throughout the process. Compared to traditional open-loop dust collection or manual material shoveling methods, this closed-loop airflow design not only significantly improves material recovery rates and avoids waste of valuable materials, but more importantly, it cuts off the path of harmful dust transmission into the working environment, effectively protecting the respiratory health and occupational safety of operators and meeting the stringent environmental and occupational health requirements of modern industrial production. It should be noted that the negative pressure generator can be in the form of various negative pressure sources such as Roots blowers, centrifugal blowers, vacuum generators, or Venturi tubes; the storage silo 42 can also integrate a filtration and separation device to achieve clean emissions after gas-solid separation. These variations are all within the scope of protection of this invention.

[0044] In another embodiment of the present invention, a conveying mechanism 7 and a pressure monitoring device 8 are also included; the conveying mechanism 7 is disposed at the bottom of the frame 1 and configured to carry and convey the container 9 to the working position below the stripping actuator 3; the pressure monitoring device 8 is installed on the inner side wall of the conveying mechanism 7 and configured to monitor the pressure between the container 9 and the conveying mechanism 7 in real time, and feed the pressure signal back to the control system to adjust the running length of the conveying mechanism 7.

[0045] Specifically, the conveying mechanism 7 is responsible for the automatic transfer and precise positioning of the container 9 in the production line, enabling the container 9 to be stably transferred to the stripping operation area without manual handling and alignment. This not only reduces the labor intensity of operators but also ensures the consistency of the initial position of the container 9 relative to the stripping actuator 3 during each operation, providing a reliable benchmark for subsequent radial adaptive adjustment. It should be understood that the specific implementation of the conveying mechanism 7 is not limited to the electric push rod and slide rail structure shown in the figure. It can also be a belt conveyor, chain conveyor line, roller conveyor unit, or AGV trolley, etc., as long as it can realize the function of carrying and fixed-point conveying of the container 9, it falls within the protection scope of this embodiment.

[0046] A pressure monitoring component 8 is installed on the inner wall of the conveying mechanism 7 to monitor the pressure between the container 9 and the conveying mechanism 7 in real time and feed the pressure signal back to the control system to adjust the running length of the conveying mechanism 7. This design establishes a flexible protective closed-loop mechanism for the container 9. In actual operation, since the container 9 (such as a graphite crucible) is usually made of brittle materials with limited compressive strength, if the positioning thrust of the conveying mechanism 7 is too large or the stroke is too long, the container 9 is prone to cracking or hidden damage due to interference compression, resulting in costly material loss and safety hazards. In this embodiment, the pressure monitoring component 8 senses the contact force in the clamping or abutting state in real time. When the detected pressure value approaches the preset safety threshold, the control system immediately instructs the conveying mechanism 7 to stop advancing or retract for fine adjustment, thereby keeping the force within the safe bearing range of the container 9. This dynamic adjustment strategy based on force feedback fundamentally eliminates the risk of breakage caused by rigid positioning and significantly improves the operational safety of the equipment and the product yield. It should be noted that the pressure monitoring component 8 can be a variety of mechanical sensing elements such as strain gauge pressure sensor, thin film pressure switch, piezoelectric ceramic sensor or torque sensor; its installation position is not limited to the inner wall of the conveying mechanism 7, and can also be set below the bearing platform, at the end of the clamping arm or other positions that can directly or indirectly reflect the force state of the container 9. All these variations are within the protection scope of the present invention.

[0047] Through the cooperation of the aforementioned conveying mechanism 7 and pressure monitoring component 8, this embodiment not only ensures the core stripping and collection function, but also improves the automated logistics interface and safety protection system of the whole machine, enabling the device to be seamlessly integrated into the continuous production line, and still maintain reliable protection of the vulnerable container 9 under unattended operation, demonstrating the maturity and practicality of the equipment in industrial applications.

[0048] This embodiment provides a method for peeling and removing surface materials. This method is implemented based on the apparatus described in the foregoing embodiment, and reproduces the dynamic collaborative process of radial adaptive peeling and in-situ follow-up collection from an execution perspective. Specifically, the method includes the following steps: In step S100, the peeling actuator 3 is placed inside the container 9, and the radial extension length of the peeling end of the peeling actuator 3 is adjusted so that the peeling end fits against the inner wall of the container 9. In this step, the adjustment action is a crucial step in establishing the operational baseline. Specifically, the operator or control system, based on the specifications of the container 9 to be processed, instructs the radial adjustment drive mechanism to push the peeling end outward or inward along the guide assembly until the working surface of the peeling end forms a preset contact pressure or gap with the inner wall of the container 9. This active adjustment mechanism allows the same set of peeling actuators 3 to seamlessly adapt to containers 9 of various inner diameters without the need to change tooling fixtures. It should be understood that establishing the fit is not only for determining the geometric position but also for providing stable radial support force during subsequent high-speed rotational peeling, preventing the peeling end from shaking or deviating from its trajectory due to centrifugal force or cutting reaction force. In some preferred embodiments, this adjustment process can be performed while the peeling actuator 3 is rotating at low speed, utilizing the rotational homogenization effect to automatically align the peeling end with the center of the container 9, further improving the coaxiality and uniformity of the fit.

[0049] In step S200, the peeling end is driven to rotate to peel off the material adhering to the inner wall of container 9. After radial adhesion is completed, the rotation drive mechanism 2 outputs torque to drive the peeling end to rotate at high speed around the axis. Specifically, the tangential velocity generated by the rotation causes the peeling blade to form a continuous shearing and scraping action relative to the adhering material, gradually peeling off the material layer that has solidified or adhered to the inner wall of container 9. During this process, the peeling end always maintains the radially extended state set in step S to ensure the consistency of the scraping depth. The setting of the rotation speed needs to take into account the hardness and viscosity of the adhering material as well as the wear resistance of the container 9 material. For example, a higher rotation speed can be used for brittle hard crusts to improve crushing efficiency, while a medium to low rotation speed is suitable for sticky soft materials to avoid excessive crushing of the material and increased difficulty in subsequent collection. In addition, if the peeling actuator 3 includes guide vanes 32, the rotation action also generates a centripetal airflow field, providing an aerodynamic basis for subsequent material aggregation.

[0050] In step S300, during the rotating peeling process at the peeling end, the attached material that has been peeled off is sucked in situ through the suction port 41, which is positioned adjacent to the peeling actuator 3. This step is the core feature that distinguishes this method from the existing technology of "peeling first and then vacuuming" or "fixed-point vacuuming". Specifically, "during the rotating peeling process at the peeling end" limits the complete overlap of the suction action and the peeling action on the time axis, that is, as long as peeling is in progress, suction is performed synchronously without any time lag; "adjacent positioning" limits the constant coupling relationship between the suction port 41 and the peeling end in spatial position. No matter what rotational phase or lifting height the peeling end is in, the suction port 41 always moves closely with it and maintains the optimal capture distance. This spatiotemporal dual synchronization mechanism ensures that the attached material enters the effective negative pressure zone immediately after detaching from the inner wall of the container 9, completely eliminating the flight and escape path of the material from the peeling point to the suction point. Compared to traditional step-by-step operations, this method achieves efficient coupling of mechanical stripping kinetic energy and pneumatic transport kinetic energy at the microscopic scale, which not only significantly improves the material recovery rate but also cuts off the channel for dust diffusion into the environment at the source. It should be understood that the effect of in-situ suction can be further enhanced by the mechanical pushing and pneumatic gathering action of the guide vanes 32 in the aforementioned embodiment, actively converging the stripped material dispersed in the edge area to the vicinity of the suction port 41, thereby achieving higher collection efficiency with lower negative pressure energy consumption.

[0051] Through the sequential coordinated execution of steps S100 to S300, this method fully replicates the core functional logic of the device at the process level, achieving efficient, dust-free, and adaptive stripping and collection of materials adhering to the inner wall of multi-specification containers 9. It should be noted that although this embodiment describes the steps in a specific order, in actual operation, there may be parallel or iterative processes between the steps. For example, in continuous lifting and stripping operations, radial adjustment may be dynamically fine-tuned with changes in depth. These variations all fall within the protection scope of this invention.

[0052] This embodiment provides a surface material stripping and removal system. The system includes a material stripping and collection device for the inner wall of container 9 as described in the previous embodiment, a control cabinet communicatively connected to the material stripping and collection device, and upstream and downstream conveyor lines for transporting container 9. This embodiment aims to integrate the aforementioned single-unit device into an automated production line, achieving continuous and unmanned material handling operations through system-level collaborative control. It should be noted that although this embodiment uses the surface material processing of graphite crucibles in the production of artificial graphite anode materials as a specific application scenario, this is only a typical application example of the technical solution of this invention and does not constitute a limitation on the scope of protection of this invention. This system is also applicable to other fields requiring automated stripping and collection of deposits on the inner walls of cylindrical or basin-shaped containers 9, such as chemical, metallurgical, food, or pharmaceutical industries.

[0053] Specifically, after the graphitization process of the graphite anode material, a layer of surface material containing impurities usually adheres to the inner wall of the graphite crucible. This layer needs to be peeled off and recycled for subsequent purification and reuse. In the material handling system of this embodiment, the upstream and downstream conveyor lines constitute the main logistics transmission backbone. The upstream end connects to the discharge station of the graphitization furnace, and the downstream end connects to the clean crucible temporary storage area or the next processing step. The control cabinet, as the nerve center of the system, integrates a PLC controller, a human-machine interface, and an electrical drive unit. It establishes communication connections with the rotary drive mechanism 2, lifting drive mechanism 5, radial adjustment drive mechanism, negative pressure generator, and drive motors of the upstream and downstream conveyor lines in the material peeling and collection device on the inner wall of container 9, respectively, to achieve logical interlocking and parameter linkage throughout the entire process.

[0054] In actual operation, the system executes the following automated workflow: First, the graphite crucible loaded with the surface material to be processed is transferred to the stripping station via the upstream conveyor line. The pressure monitoring device 8 on the conveying mechanism 7 provides real-time feedback of the clamping force signal to the control cabinet. When the pressure reaches the preset safety threshold, the conveying mechanism 7 automatically stops and locks its position, ensuring accurate positioning of the crucible and preventing brittle crucible breakage due to interference compression. Subsequently, the control cabinet instructs the lifting drive mechanism 5 to lower the stripping actuator 3 and the suction assembly 4 to the preset depth inside the crucible. At the same time, the radial adjustment drive mechanism automatically adjusts the extension length of the stripping end according to the current crucible specifications, ensuring it precisely fits the inner wall of the crucible. Immediately afterward, the rotary drive mechanism 2 starts, and the stripping end rotates at high speed to shear and scrape the surface material. Simultaneously, the negative pressure generator is activated, and the adjacent suction port 41, with the centripetal convergence assistance of the guide vanes 32, promptly sucks in the dust and particles generated during the stripping process into the closed air passage and transports them to the storage bin 42. After a certain depth of peeling is completed, the lifting drive mechanism 5 is raised at a preset step distance, and the above action is repeated until the entire inner wall of the crucible is cleaned. Finally, the peeling actuator 3 is reset and raised, the downstream conveyor line transports the clean crucible out, and the upstream conveyor line sends the next crucible to be processed, forming a continuous cycle operation.

[0055] Through the aforementioned system integration, this embodiment achieves a leap from single-device functionality to production line-level efficiency. Compared to traditional manual material handling or semi-automatic single-machine operations, this system not only significantly reduces the processing time of a single crucible and substantially improves production cycle time, but more importantly, it constructs a fully enclosed, automated, dust-free operating environment, completely solving the environmental pain points of graphite powder being easily scattered and difficult to collect, and ensuring the occupational health of operators. Simultaneously, the flexible positioning and radial adaptive stripping mechanism based on pressure feedback effectively reduces the loss rate of expensive graphite crucibles, improving overall yield and economic benefits. It should be understood that the control cabinet in this embodiment can be an independent electrical cabinet or an intelligent industrial control computer integrating edge computing capabilities; the upstream and downstream conveyor lines can be roller conveyors, chain conveyors, belt conveyors, or AGV logistics systems; the communication connection method can be a wired bus, industrial Ethernet, or wireless communication protocol. These variations all fall within the protection scope of the material handling system of this invention.
