Description

Technical Field

[0001] This application relates to the field of steel plate and composite plate cleaning technology, and in particular to a steel plate adhesive roller assembly that allows for the replacement of adhesive paper without stopping the machine. Background Technology

[0002] In the deep processing of steel plates and composite panels, surface coating is a core and crucial process for improving the overall performance of the panels, including corrosion resistance, wear resistance, and decorative properties. It is widely used in many industrial fields such as steel structures, building materials decoration, precision sheet metal, and appliance panels. During the initial processing stages, including cutting, grinding, conveying, and storage, the surface of the panels is highly susceptible to contaminants such as dust, metal shavings, particulate impurities, and fibrous debris. If these impurities are not thoroughly removed before coating, it will directly lead to quality defects such as insufficient coating adhesion, blistering, pinholes, orange peel texture, and raised particles. This not only significantly reduces the finished product yield but also affects the accuracy of subsequent processing such as bending, bonding, and assembly, severely restricting overall product quality and market reputation. Therefore, high-precision, continuous surface dust removal treatment before coating is a necessary pre-process to ensure the quality of steel plate and composite panel coating.

[0003] Currently, the mainstream equipment for surface dust removal operations before coating steel plates and composite panels in the industry is the traditional adhesive roller dust removal device. Its core structure is a metal roller wrapped with adhesive paper. By relying on the adhesiveness of the adhesive paper surface to contact the plate surface, dust and particulate impurities are adsorbed and removed. Compared with dust removal by blowing or brushing, it has the advantages of high dust removal accuracy, no secondary dust generation, and suitability for processing flat plates. It is widely used in plate pretreatment production lines.

[0004] However, adhesive paper is a disposable consumable with a limited adsorption capacity per use. As dust removal continues, the surface of the adhesive paper quickly accumulates dust, debris, and other impurities, significantly reducing its stickiness and drastically decreasing its dust removal efficiency. If not replaced in time, it cannot meet the high-precision dust removal standards for boards, directly causing poor coating of batches of boards. Currently, the replacement of adhesive paper relies entirely on manual operation. When the adhesive paper becomes ineffective, the entire board processing production line must be stopped, and the old adhesive paper must be manually torn off and new adhesive paper re-wrapped and pasted. Production can only be restarted after the replacement is completed and the equipment is properly debugged. This replacement process is cumbersome and time-consuming, causing frequent production line shutdowns and significantly reducing the continuous processing efficiency of boards, making it unsuitable for high-speed assembly line production.

[0005] In summary, existing traditional adhesive roller dust removal equipment suffers from numerous drawbacks, such as frequent consumable replacements, the need for manual operation during downtime, poor production continuity, and low processing efficiency. It cannot meet the current production demands for high-precision, high-efficiency, and automated continuous dust removal in steel plates and composite panels. Therefore, there is an urgent need to develop an adhesive roller assembly equipment that can achieve downtime-free, automatic paper changing, and continuous and efficient dust removal to address the core pain points of existing technologies. Summary of the Invention

[0006] In order to replace the adhesive paper without stopping the machine and improve the dust removal efficiency, this application provides a steel plate adhesive roller assembly for replacing the adhesive paper without stopping the machine.

[0007] The technical solution provided in this application for a steel plate adhesive roller assembly that allows for non-stop replacement of adhesive paper is as follows: A steel plate sticky roller assembly for non-stop sticky paper replacement includes a frame with two sets of dust removal mechanisms symmetrically arranged on the frame. Each dust removal mechanism includes a rubber roller and a sticky roller rotatably connected to the frame. The axes of the sticky roller and the rubber roller are parallel to each other and are in contact with each other. A steel plate passes between the two rubber rollers. Multiple layers of sticky paper are wound around the outside of the sticky roller. The multiple layers of sticky paper are stacked and wound radially around the outer wall of the roller. Adjacent layers of sticky paper are separated from each other and are set independently. A winding assembly that automatically hooks up a single layer of sticky paper is provided on the frame.

[0008] By adopting the above technical solution, when the user uses the equipment, the steel plate passes between the rubber rollers of the two sets of dust removal mechanisms. The rubber rollers rotate and squeeze the conveyed steel plate, fully adhering to the surface of the steel plate, transferring and adsorbing impurities such as dust and iron powder on the surface of the steel plate to their own roller surface. The outer wall of the adhesive roller is wrapped with multiple layers of independent, non-adhesive adhesive paper, which remains in constant contact with the rubber roller surface. This allows for the continuous re-adhesion and absorption of various impurities adsorbed by the rubber roller, thoroughly cleaning the roller surface and ensuring effective dust removal. This enables continuous and efficient dust removal for steel plates. When the outermost layer of adhesive paper becomes saturated with dust and loses its stickiness after prolonged use, the winding assembly on the frame precisely hooks and separates the damaged single layer of adhesive paper from the roller surface without disturbing the intact inner layer. The winding assembly then winds up at a uniform speed, completely peeling off the waste paper. After the surface waste paper is removed, a new, independent layer of adhesive paper is automatically exposed on the outer wall of the roller. This new paper immediately contacts and adheres to the rubber roller, quickly restoring the dust removal operation. The two dust removal mechanisms can complete the paper replacement operation independently or simultaneously, adapting to the double-sided dust removal needs of steel plates. The equipment requires no downtime for paper replacement, avoiding production line interruptions caused by traditional equipment downtime for material changes, and significantly improving the continuous production efficiency of steel plates. Featuring a layered, independent adhesive paper peel-off design, it allows for precise replacement of damaged paper layers without wasting intact adhesive paper, effectively saving on consumable costs. Simultaneously, it automates paper changing, eliminating the need for frequent manual monitoring and roll replacement, reducing labor intensity and on-site operational safety hazards.

[0009] Optionally, the sticky roller is detachably connected to the frame. The frame has mounting holes on both sides corresponding to the position of the sticky roller. A positioning plate is fixedly connected to the mounting hole with bolts. A slider is slidably connected to the positioning plate. The two ends of the roller shaft of the sticky roller are fixedly connected to the slider. A guide post is fixedly connected to the top of the slider. The guide post is vertically slidably connected to the positioning plate. A return spring is provided on the outer sleeve of the guide post.

[0010] By adopting the above technical solution, during user operation, the return spring can drive the slider and the dust-adhesive roller to slide vertically adaptively along the guide column, ensuring that the dust-adhesive roller always elastically abuts against the rubber roller. This adapts to variations in steel plate thickness and conveyor vibrations, avoiding issues such as gaps or excessive compression caused by rigid contact, and ensuring uniform and stable adhesion pressure, effectively improving dust removal consistency. For later maintenance, the roller can be quickly disassembled and installed directly through the frame mounting port without disassembling the entire machine structure, significantly simplifying the maintenance process and improving repair efficiency.

[0011] Optionally, the winding assembly includes a take-up motor connected to both symmetrical sides of the frame. A screw is fixedly connected to the output shaft of the take-up motor. A limit plate is fixedly connected to the frame. The screw passes through the limit plate and is threadedly connected to the limit plate. A hook is fixedly connected to the end of the screw. A retaining ring is provided at the end of each layer of adhesive paper. The retaining ring is used for the hook to be inserted. A drive assembly is provided inside the frame to drive the screw to move vertically and drive the hook to take the adhesive paper downward.

[0012] By adopting the above technical solution, during operation, the take-up motor drives the screw to rotate. The screw and the limiting plate form a threaded transmission, driving the end hook to feed vertically upward, allowing the hook to accurately engage and lock the retaining ring of the surface layer of expired adhesive paper. As the adhesive paper is peeled off layer by layer and consumed, the outer diameter of the paper layer continuously decreases, and the position of the retaining ring gradually approaches the center of the roller shaft. The screw can adaptively adjust the lifting stroke to ensure that the hook always accurately engages and hooks the retaining ring, preventing disengagement or missed hooking. After the engagement and positioning are completed, the drive component inside the frame is activated, driving the screw and the hook to move vertically downward as a whole, pulling the expired adhesive paper smoothly off the peeling roller, realizing automatic downward conveying and centralized collection of waste paper layers, and automatically completing the single-layer waste paper separation and winding operation throughout the entire process.

[0013] Optionally, the drive assembly includes a support plate fixedly connected to the frame, a drive motor fixedly connected to the support plate, a bidirectional reciprocating screw fixedly connected to the output shaft of the drive motor, a sliding plate threadedly connected to the bidirectional reciprocating screw, connecting plates fixedly connected to both sides of the sliding plate, and a limit plate and a take-up motor fixedly connected to the connecting plates.

[0014] By adopting the above technical solution, during operation, the drive motor drives the vertically arranged bidirectional reciprocating screw to rotate, causing the sliding plate to make a stable vertical linear reciprocating motion along the guide column. This, in turn, drives the limiting plate, the take-up motor, the screw, and the latch to move downwards synchronously, pulling the locked and deactivated adhesive paper downwards at a uniform speed. This ensures the waste adhesive paper is smoothly and completely removed from the adhesive roller, completing automatic peeling and waste collection. After the operation is completed, the drive assembly can reset the entire structure, awaiting the next paper replacement operation.

[0015] Optionally, two guide plates are fixedly connected to the inner wall of the frame, forming a feeding gap between the guide plates. The screw and the hook are located at both ends of the feeding gap between the two guide plates. A receiving box is provided at the bottom of the guide plate. A feeding roller is rotatably connected to the receiving box near the guide plate. A guide slope is opened at the bottom of one of the guide plates. The guide slope and the feeding roller cooperate to guide the sticky paper into the receiving box.

[0016] By adopting the above technical solution, during the user's operation, when the sticky paper is peeled off downwards due to the hook traction failure, the sticky paper moves vertically downwards along the feeding gap between the guide plates, effectively limiting lateral deviation and ensuring a neat and centered feeding trajectory. When the sticky paper reaches the bottom of the guide plate, the guide slope of one side of the guide plate guides the paper at an angle, which, together with the rotatable feeding roller, assists in conveying and reduces frictional resistance, allowing the peeled waste sticky paper to smoothly turn and be smoothly guided into the collection box below, completing the automatic centralized collection of waste. The double guide plate limit constraint on the movement trajectory of the waste paper can effectively prevent the waste sticky paper from deviating, wrinkling, or jamming, ensuring a smooth and unblocked feeding process. The guide slope and the rotating feeding roller work together to significantly reduce the pulling and wear of the sticky paper as it descends, avoiding problems such as tearing and residue sticking to the wall, and improving the integrity and stability of the feeding process.

[0017] Optionally, the roller shaft of the adhesive roller is symmetrically provided with slots at both ends, each slot having a different depth. Two locking rods are fixedly connected to the edge of each layer of adhesive paper, the locking rods are locked into the slots, and the locking rings are fixedly connected to the locking rods.

[0018] By adopting the above technical solution, when the user uses the structure, the multiple layers of adhesive paper can be arranged independently and in a staggered manner along the radial direction of the roller, which completely avoids interlayer adhesion and mutual entanglement, and ensures that only the outer layer of the failed paper is peeled off by force when changing paper, without causing the inner layer of new paper to loosen and shift.

[0019] Optionally, electrodes are provided on the inner wall of the frame at positions corresponding to the two rubber rollers. The electrodes abut against the ends of the rubber rollers. The rubber rollers are made of semi-conductive rubber. The electrodes are used to generate static electricity on the surface of the rubber rollers to attract dust from the steel plate.

[0020] By adopting the above technical solution, users continuously energize the conductive rubber roller during use, causing a uniform electrostatic adsorption force to be generated on the surface of the rubber roller. This electrostatic adsorption principle captures fine dust, floating impurities, and lightweight particles from the steel plate surface, overcoming the limitation of purely physical contact dust removal methods in cleaning fine dust. Compared to traditional purely adhesive dust removal methods, electrostatic dust removal significantly improves cleanliness, thoroughly removing ultrafine dust from the steel plate surface and eliminating the residue of fine impurities. Simultaneously, the selected conductive rubber material possesses excellent conductivity, wear resistance, and elasticity, stabilizing the electrostatic field to ensure uniform and continuous electrostatic adsorption, while also allowing for flexible extrusion and conveying of the steel plate, preventing scratches and indentations.

[0021] Optionally, a positioning column is slidably connected to the frame, the electrode is fixedly connected to the end of the positioning column, and a compression spring is sleeved on the positioning column, with the compression spring located between the electrode and the frame.

[0022] By adopting the above technical solution, when the user uses the device, the clamping spring continuously provides elastic clamping force to push the positioning column to slide and feed, so that the electrode is always in close contact with the end of the rubber roller. This can effectively compensate for the wear of the roller body rotation, assembly gaps and contact gaps caused by equipment vibration, and avoid problems such as loose electrode contact, poor connection and power failure.

[0023] Optionally, the rubber roller is fitted with an isolation sleeve on its outer casing to isolate static electricity.

[0024] By adopting the above technical solution, when the user uses the device, the electrodes energize the rubber roller body to generate static electricity. The isolation cylinder can effectively prevent the static electricity of the rubber roller body from being conducted to the metal roller shaft, accurately locking the static electricity in the working area on the surface of the rubber roller, avoiding static electricity loss and dispersion. This not only accurately limits the electrostatic field and prevents static electricity from being conducted along the roller shaft to metal parts such as the frame and transmission structure, avoiding the risk of the whole machine being electrified or leaking electricity, but also improves the safety of equipment operation. Furthermore, it can eliminate static electricity shunting loss, ensure that the static electricity strength on the surface of the rubber roller is stable and sufficient, avoid the decrease in dust removal capacity due to static electricity decay, and continuously ensure the adsorption effect of fine dust.

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0029] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0030] This application discloses a steel plate adhesive roller assembly for replacing adhesive paper without shutting down the machine, as shown in the following embodiments. Figure 1The system includes a frame 1 and two sets of dust removal mechanisms 2 symmetrically arranged on the frame 1. The two sets of dust removal mechanisms 2 are arranged vertically, and steel plates pass through the two sets of dust removal mechanisms 2 to remove dust from both sides of the steel plates. The two sets of dust removal mechanisms 2 have the same structure, and the following description uses one set as an example.

[0031] Reference Figure 2 The dust removal mechanism 2 includes a rubber roller 21 and a dust-adhesive roller 22 rotatably connected to the frame 1. The axes of the dust-adhesive roller and the rubber roller 21 are parallel to each other and the dust-adhesive roller 22 and the rubber roller 21 are abutted together. A steel plate passes through the space between the two rubber rollers 21. A power motor 215 is connected to one of the rubber rollers 21. Multiple layers of dust-adhesive paper 221 are wound around the outside of the dust-adhesive roller 22. The rolls of multiple layers of dust-adhesive paper 221 are stacked and wound radially around the outer wall of the roller. Adjacent rolls of dust-adhesive paper are separated from each other and set independently. A winding assembly 23 that automatically hooks up a single layer of dust-adhesive paper is provided on the frame 1. This structural design allows the rubber roller 21 and the adhesive roller 22 to work together to continuously and effectively adsorb impurities on the surface of the steel plate during dust removal operations. Moreover, when the adhesive paper becomes ineffective, the winding assembly 23 can precisely peel off the ineffective single layer of adhesive paper, enabling paper replacement without stopping the machine. This significantly improves the continuous production efficiency of steel plates. At the same time, the layered independent adhesive paper peeling design allows for precise replacement of ineffective paper layers, avoiding waste of intact adhesive paper and effectively saving consumable costs.

[0032] Reference Figure 2 and Figure 3 Specifically, the rubber roller 21 includes a roller body and a roller shaft. The roller body is made of semi-conductive rubber, such as conductive nitrile rubber, conductive chloroprene rubber, and conductive polyurethane. These rubber materials combine good conductivity, wear resistance, and elasticity, stabilizing the electrostatic field to ensure uniform and continuous electrostatic adsorption, while also allowing for flexible extrusion and conveying of the steel plate, avoiding scratches and indentations. The roller shaft supports the roller body and enables rotation. During installation, the roller body is fitted onto the roller shaft, with the two fitting tightly to ensure stable rotation of the rubber roller 21. The power motor 215 can be directly connected and fixed to the roller shaft, or it can be connected to the roller shaft of the rubber roller 21 through a transmission device to provide power for the rotation of the rubber roller 21. The transmission device can be a belt drive, chain drive, or gear drive, etc. For example, when using a belt drive, a drive pulley is installed on the output shaft of the power motor 215, and a driven pulley is installed on the roller shaft of the rubber roller 21. The drive pulley and the driven pulley are connected by a belt, so when the power motor 215 rotates, it drives the rubber roller 21 to rotate.

[0033] Electrodes 211 are positioned on the inner wall of the frame 1 corresponding to the positions of the two rubber rollers 21. The electrodes 211 abut against the ends of the rubber rollers 21, and the electrodes 211 generate static electricity on the surface of the rubber rollers 21 to attract dust from the steel plate. A positioning post 212 is slidably connected to the frame 1, and the electrodes 211 are fixedly connected to the ends of the positioning post 212. A compression spring 213 is sleeved on the positioning post 212, and the compression spring 213 is located between the electrodes 211 and the frame 1. The electrodes 211 continuously energize the conductive rubber rollers 21, causing the surface of the rubber rollers 21 to generate a uniform electrostatic adsorption force. Relying on the principle of electrostatic adsorption, it captures fine dust, floating impurities, and light particles on the surface of the steel plate, overcoming the shortcomings of pure physical contact dust removal in cleaning fine dust. Compared with traditional pure adhesive dust removal methods, electrostatic dust removal can significantly improve cleanliness, thoroughly remove ultrafine dust from the surface of the steel plate, and eliminate the residue of fine impurities. The compression spring 213 continuously provides elastic clamping force, pushing the positioning column 212 to slide and feed, so that the electrode 211 is always in close contact with the end of the rubber roller 21. This can effectively compensate for the wear of the roller body rotation, assembly gaps and contact gaps caused by equipment vibration, and avoid problems such as loose contact, poor connection and power failure of the electrode 211.

[0034] Specifically, the rubber roller 21 has an isolation cylinder 214 surrounding its roller shaft, which is used to isolate static electricity. The electrode 211 energizes the rubber roller 21 to generate static electricity, and the isolation cylinder 214 can effectively prevent the static electricity on the rubber roller 21 from being conducted to the metal roller shaft, precisely locking the static electricity in the working area on the surface of the rubber roller 21, preventing static electricity loss and dispersion. This not only precisely limits the electrostatic field and prevents static electricity from being conducted along the roller shaft to metal parts such as the frame 1 and transmission structure, avoiding the risk of the whole machine being electrified or leaking current, but also eliminates static electricity shunting loss, ensuring that the static electricity strength on the surface of the rubber roller 21 is stable and sufficient, preventing the dust removal capacity from decreasing due to static electricity decay, and continuously ensuring the adsorption effect of fine dust.

[0035] Reference Figure 1 and Figure 4The dust-adhesive roller 22 is detachably connected to the frame 1. Mounting ports 11 are provided on both sides of the frame 1 corresponding to the positions of the dust-adhesive roller 22. Positioning plates 12 are bolted to the mounting ports 11. Vertical grooves 121 are provided within the positioning plates 12, and sliders 122 are slidably connected within the grooves 121. Both ends of the roller shaft of the dust-adhesive roller 22 are fixedly connected to the sliders 122. A guide shaft 123 is fixedly connected to the top of the sliders 122 and slidably connected to the positioning plates 12. A return spring 124 is fitted over the guide shaft 123. The return spring 124 can drive the sliders 122 and the dust-adhesive roller 22 to slide vertically adaptively along the guide shaft 123, ensuring that the dust-adhesive roller 22 always elastically abuts against the rubber roller 21. This adapts to variations in steel plate thickness and conveying vibrations, avoiding gaps or excessive compression caused by rigid contact, ensuring uniform and stable bonding pressure, and effectively improving dust removal consistency. During later maintenance, the rollers can be quickly installed and removed directly through the mounting port 11 on the frame 1 without disassembling the entire machine structure, which greatly simplifies the maintenance process and improves maintenance efficiency.

[0036] During dust removal operations, the elasticity of the return spring 124 allows the sticky roller 22 to adaptively adjust its position, ensuring good contact with the rubber roller 21 and thus improving the dust removal effect. The detachable design facilitates later maintenance and repair, reducing maintenance time and costs, and improving the overall operating efficiency of the equipment.

[0037] Specifically, the adhesive roller 22 includes a roller shaft and multiple layers of adhesive paper 221. The roller shaft supports the adhesive paper and allows it to rotate, with both ends rotatably connected to the frame 1. The multiple layers of adhesive paper 221 are stacked and wound radially around the outer wall of the roller shaft, with adjacent layers of adhesive paper separated from each other and operating independently. To achieve this independent arrangement, multiple slots 222 are symmetrically provided at both ends of the roller shaft of the adhesive roller 22. Each slot 222 has a different depth, and two locking rods 223 are fixedly connected to the edge of each layer of adhesive paper. The locking rods 223 are engaged in the slots 222, and retaining rings 224 are fixedly connected to the locking rods 223. The slots 222 extend from the edge of the roller shaft of the adhesive roller 22 towards the center. The closer to the inner layer of adhesive paper, the longer the locking rods 223 are, and the deeper the corresponding slots 222 are. This structure allows the multi-layer adhesive paper 221 to be arranged independently and in a staggered manner along the radial direction of the roller, completely avoiding interlayer adhesion and mutual entanglement. This ensures that only the outer, damaged paper layer is subjected to force and peeled off during paper replacement, without causing the inner, new paper layer to loosen or shift. The depth-differentiated slots 222 and the length-matching latching rods 223 precisely adapt to the changes in the diameter of each paper layer, ensuring that the latching rings 224 of each layer of adhesive paper are always in the standard docking position for the corresponding layer. This allows the hooks 234 to stably and accurately hook the latching rings 224 regardless of the depth of paper layer consumption, effectively solving the problems of docking deviation and hook failure after the paper layer decreases.

[0038] Reference Figure 5Specifically, the take-up assembly 23 includes take-up motors 231 connected to the symmetrical sides of the frame 1. A screw 232 is fixedly connected to the output shaft of the take-up motor 231. A limit plate 233 is fixedly connected to the frame 1. The screw 232 passes through the limit plate 233 and is threadedly connected to the limit plate 233. A hook 234 is fixedly connected to the end of the screw 232. Each layer of adhesive paper has a retaining ring 224 at its end for the hook 234 to insert into. A drive assembly 24 is provided inside the frame 1 to drive the screw 232 to move vertically and drive the hook 234 to take the adhesive paper downward. When the take-up motor 231 drives the screw 232 to rotate, the screw 232 and the limit plate 233 form a threaded transmission, driving the end hook 234 to feed vertically upward, so that the hook 234 accurately inserts into and locks the retaining ring 224 of the surface layer of failed adhesive paper. As the adhesive paper is peeled off layer by layer and consumed, the outer diameter of the paper layer continuously decreases. The position of the retaining ring 224 gradually approaches the center of the roller shaft. The screw 232 can adaptively adjust its lifting stroke to ensure that the hook 234 always accurately aligns with and engages the retaining ring 224, preventing any disengagement or missed hooking. After the snap-fit ​​positioning is completed, the drive assembly 24 on the inner side of the frame 1 is activated, driving the screw 232 and the hook 234 to move vertically downwards as a whole. This pulls the exhausted adhesive paper smoothly off the roller, realizing the automatic downward conveying and centralized collection of waste paper layers. The entire process of single-layer waste paper separation and winding is completed automatically.

[0039] Specifically, the drive assembly 24 includes a support plate 241 fixedly connected to the frame 1, a drive motor 242 fixedly connected to the support plate 241, a bidirectional reciprocating screw 243 fixedly connected to the output shaft of the drive motor 242, a sliding plate 244 threadedly connected to the bidirectional reciprocating screw 243, a guide post 245 fixedly connected to the support plate 241, and the two sides of the sliding plate 244 slidably connected to the guide post 245. The axial directions of the bidirectional reciprocating screw 243 and the guide post 245 are both vertically arranged. Connecting plates 246 are fixedly connected to the two sides of the sliding plate 244, and the limiting plate 233 and the receiving motor are both fixedly connected to the connecting plate 246. When the drive motor 242 drives the vertically arranged bidirectional reciprocating screw 243 to rotate, it drives the sliding plate 244 to make a stable vertical linear reciprocating motion along the guide column 245. In turn, through the connecting plate 246, it drives the limit plate 233, the take-up motor 231, the screw 232 and the hook 234 to move down synchronously, pulling the locked and deactivated sticky paper down at a uniform speed, so that the waste sticky paper is smoothly and completely separated from the sticky roller 22, completing the automatic peeling and waste collection. After the operation is completed, the drive assembly 24 can drive the entire structure to reset, waiting for the next paper change operation.

[0040] Reference Figure 6Specifically, two guide plates 25 are fixedly connected to the inner wall of the frame 1, forming a feeding gap between the guide plates 25. The screw 232 and the hook 234 are located at both ends of the feeding gap between the two guide plates 25. A receiving box 251 is provided at the bottom of the guide plate 25. A feeding roller 252 is rotatably connected to the receiving box 251 near the guide plate 25. A motor is connected to the feeding roller 252. A guide slope 253 is opened at the bottom of one of the guide plates 25. The guide slope 253 and the feeding roller 252 cooperate to guide the sticky paper into the receiving box 251. During the downward peeling of the sticky paper due to the failure of the hook 234, the sticky paper moves vertically downward along the feeding gap between the guide plates 25, effectively limiting lateral deviation and ensuring a neat and centered feeding trajectory. When the sticky paper reaches the bottom of the guide plate 25, the guide slope 253 of one guide plate 25 guides the paper at an angle, which, together with the rotatable feeding roller 252, assists in conveying and reduces frictional resistance, allowing the peeled waste sticky paper to smoothly turn and be smoothly guided into the lower collection box 251, completing the automatic centralized collection of waste. The double guide plates 25 limit and constrain the movement trajectory of the waste paper, effectively preventing the waste sticky paper from deviating, wrinkling, or jamming, ensuring a smooth feeding process without blockage. The guide slope 253 and the rotating feeding roller 252 work together to significantly reduce the pulling and wear of the sticky paper as it descends, avoiding problems such as tearing and residue sticking to the wall, and improving the integrity and stability of the feeding process.

[0041] The implementation principle of this embodiment is as follows: When performing dust removal operations on steel plates, the power motor 215 drives the rubber roller 21 to rotate, and the rubber roller 21 fully adheres to the steel plate, transferring and adsorbing impurities such as dust and iron powder from the surface of the steel plate to its own roller surface. The multiple layers of independent adhesive paper wrapped around the outer wall of the adhesive roller 22 are always in contact with the surface of the rubber roller 21, continuously adsorbing various impurities adsorbed by the rubber roller 21, ensuring the cyclic dust removal effect of the rubber roller 21. When the outermost layer of adhesive paper in the adhesive roller 22 is saturated with dust and loses its adhesiveness, the take-up motor 231 drives the screw 232 to rotate, causing the hook 234 to insert and lock the retaining ring 224 of the surface adhesive paper that has lost its adhesiveness. Then, the drive assembly 24 drives the screw 232 and the hook 234 to move vertically downward as a whole, smoothly peeling the lost adhesive paper off the roller. At the same time, new adhesive paper immediately comes into contact with and adheres to the rubber roller 21, restoring the dust removal working state. In this process, the rubber roller 21 uses electrostatic discharge generated by the electrode 211 to attract fine dust from the surface of the steel plate. The isolation cylinder 214 ensures the effective utilization of static electricity, and the guide plate 25 and the feeding roller 252 ensure the smooth collection of waste adhesive paper. The entire process does not require stopping the machine to change paper, avoiding the production line interruption caused by the shutdown for material changes in traditional equipment. This significantly improves the continuous production efficiency of steel plates, while saving consumable costs and reducing the intensity of manual maintenance and on-site operational safety hazards.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
