Description

Technical Field

[0001] This utility model belongs to the field of rust removal technology, and in particular to a rust removal device for steel plate surfaces. Background Technology

[0002] During the production process of ribbon weaving machines, various steel plate components (such as frame side plates, guide plates, worktables, etc.) are required. These steel plates are prone to rust during storage or use. If they are used directly for assembly or production, it will affect the assembly accuracy and service life of the ribbon weaving machine, and may also cause scratches and contamination on the ribbon products. Existing devices have weak double-sided synchronous cleaning capabilities, which will lead to uneven rust removal of steel plates and low efficiency. Thick rust residue will affect the assembly accuracy of the ribbon weaving machine, and may also cause scratches and contamination on the ribbons. Dust dispersion will exacerbate environmental hazards and increase rework and maintenance costs.

[0003] A search revealed Chinese patent document (authorization announcement number CN212947145U), which discloses a rust removal device for steel plates used in machining. The device comprises: a base; two support plates, both fixedly mounted on the top of the base; a crossbeam fixedly mounted on the top of the two support plates; and a first groove formed at the bottom of the crossbeam. This rust removal device for steel plates provides the advantages of being able to remove rust from steel plate surfaces without dead angles and is suitable for removing rust from steel plates of various sizes. While it meets basic usage requirements, its weak ability to clean both sides simultaneously leads to uneven rust removal, low efficiency, and thick rust residue affecting the assembly accuracy of the webbing machine. It also easily causes scratches and pollution on the webbing, and dust dispersion exacerbates environmental hazards, increasing rework and maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a rust removal device for steel plate surfaces to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel plate surface rust removal device, comprising a support platform for support, a fixing frame for providing stable installation space fixedly installed on one side of the support platform, and an adjustment frame fixedly installed on the side of the fixing frame;

[0006] The adjustment frame has a circular groove inside for providing stable vertical movement space. A rotating column for limiting rotational displacement is rotatably installed inside the adjustment frame. Opposing threaded columns for providing opposing rotational forces are connected to both ends of the rotating column. An internal threaded moving frame is symmetrically threaded about the outer periphery of the opposing threaded column about the rotating column. The internal threaded moving frame is symmetrically slidably disposed up and down inside the circular groove about the rotating column.

[0007] Preferably, the ends of the opposing threaded columns are equipped with rotating handles for adjusting the position of the internal threaded moving frames, and the outer peripheries of the two internal threaded moving frames are connected with connecting rods. The interior of the fixed frame is provided with a guide groove, and a movable hollow column is fixedly installed at the end of the connecting rod away from the internal threaded moving frame.

[0008] Preferably, the movable hollow column is slidably disposed inside the guide groove, and a spring for providing adaptive thrust is connected inside the movable hollow column. The end of the spring is connected to a movable disk, and the movable disk is slidably disposed inside the movable hollow column.

[0009] Preferably, the outer periphery of the movable hollow column is connected to a support block for support, the support block has a rotating shaft inside, and the outer periphery of the rotating shaft is equipped with a rust-removing wheel for removing rust from the steel plate surface.

[0010] Preferably, a fixed plate is fixedly installed on the other side of the support platform. The surface of the fixed plate is provided with a sliding groove for sliding at the end of the rotating shaft. Two sliding plates for support are slidably connected to the side of the fixed plate away from the rust removal wheel. A second drive motor for providing stable driving force is installed on the side of the two sliding plates away from the fixed plate. The output shaft of the second drive motor is connected to the end of the rotating shaft through a coupling.

[0011] Preferably, a conveying roller for conveying steel plates is installed on the top of the support platform, a vertical support for support is fixedly installed on the side of the conveying roller, and a pressing roller for positioning the steel plates is movably connected to the side of the vertical support.

[0012] Preferably, a first drive motor for providing driving force is installed at the bottom of the support platform, and the output shaft of the first drive motor is connected to a belt drive unit via a coupling. The output end of the belt drive unit is equipped with an extrusion conveying roller group for increasing the conveying and positioning capability.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This steel plate surface rust removal device effectively solves the problem of weak double-sided synchronous cleaning capability thanks to the symmetrically arranged rust-removing wheel assembly and the adaptive elastic drive structure. The structure, through the cooperation of the opposing threaded columns of the adjustment frame and the internal threaded moving frame, can flexibly adjust the initial distance between the upper and lower rust-removing wheels to adapt to steel plates of different thicknesses. The springs inside the moving hollow columns transmit continuous elastic thrust through the moving disc, which acts on the rust-removing wheels via the support block and rotating shaft, causing them to adaptively conform to the upper and lower surfaces of the steel plate. Combined with the second drive motor driving the rust-removing wheels to rotate at high speed synchronously, it achieves double-sided synchronous rust removal. This avoids uneven rust removal caused by unilateral cleaning, significantly improves rust removal efficiency, thoroughly removes thick rust residue, and ensures the assembly accuracy of the webbing machine. The elastic fit design reduces webbing scratches and contamination caused by hard contact, reducing rework and equipment maintenance costs due to substandard rust removal.

[0015] This steel plate surface rust removal device benefits from a structure consisting of conveying rollers, pressing rollers, extrusion conveying rollers, a first drive motor, and a belt drive unit. The first drive motor drives the conveying rollers and extrusion conveying rollers to operate synchronously via the belt drive unit, forming continuous conveying power. The pressing rollers position and press the steel plate from the top, while the extrusion conveying rollers squeeze and fix it from both sides. The three components work together to prevent the steel plate from deviating or slipping during conveying. The stable conveying rhythm ensures that the steel plate passes through the high-speed rotating rust removal wheel at a uniform speed, enabling continuous rust removal operations. This improves overall work efficiency and ensures uniform rust removal on the steel plate surface. At the same time, precise positioning and conveying reduces abnormal friction between the steel plate and the rust removal wheel, further reducing the probability of scratches. Combined with the efficient cleaning effect of simultaneous double-sided rust removal, it achieves a dual improvement in rust removal quality and work efficiency, indirectly reducing subsequent processing costs.

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0025] like Figures 1 to 4 The steel plate surface rust removal device shown includes a support platform 1 for support, a fixing frame 3 for providing stable installation space is fixedly installed on one side of the support platform 1, and an adjustment frame 2 is fixedly installed on the side of the fixing frame 3.

[0026] The adjustment frame 2 has a circular slide groove 201 inside for providing stable vertical movement space. The adjustment frame 2 has a rotating column 203 inside for limiting rotational displacement. The two ends of the rotating column 203 are connected to opposing threaded columns 202 for providing opposing rotational force. The outer periphery of the opposing threaded column 202 is symmetrically threaded with an internal threaded moving frame 204 about the rotating column 203. The internal threaded moving frame 204 is symmetrically and slidably arranged up and down inside the circular slide groove 201 about the rotating column 203.

[0027] A rotating handle 205 for adjusting the position of the internal thread moving bracket 204 is installed at the end of the opposing threaded column 202. Connecting rods 206 are connected to the outer periphery of both internal thread moving brackets 204. A guide groove 301 is provided inside the fixed frame 3. A movable hollow column 302 is fixedly installed at the end of the connecting rod 206 away from the internal thread moving bracket 204. The movable hollow column 302 is slidably disposed inside the guide groove 301. A spring 303 for providing adaptive thrust is connected inside the movable hollow column 302. A movable disk 304 is connected to the end of the spring 303, and the movable disk 304 slides... The movable hollow column 302 is located inside the movable hollow column 302. The outer periphery of the movable hollow column 302 is connected to a support block 305 for support. The support block 305 has a rotating shaft 306 inside it. The outer periphery of the rotating shaft 306 is equipped with a rust-removing wheel 307 for removing rust from the steel plate surface. Rotating the rotating handle 205 on the rotating adjustment frame 2 drives the rotating column 203 and the opposing threaded columns 202 at both ends to rotate synchronously. Since the internal threaded moving frame 204 is threadedly connected to the opposing threaded column 202 and slides symmetrically in the circular slide groove 201, the two sets of internal threaded moving frames 204 move vertically in opposite directions along the circular slide groove 201. The internal threaded movable frame 204 drives the movable hollow column 302 to slide synchronously in the guide groove 301 of the fixed frame 3 via the connecting rod 206, thereby adjusting the initial distance between the upper and lower sets of rust removal wheels 307 to adapt to steel plates of different thicknesses; the spring 303 inside the movable hollow column 302 provides adaptive thrust through the movable disc 304 to ensure that the rust removal wheel 307 always fits in contact with the surface of the steel plate and avoids hard contact damage.

[0028] A fixed plate 4 is fixedly installed on the other side of the support platform 1. The surface of the fixed plate 4 is provided with a sliding groove 401 for sliding at the end of the rotating shaft 306. Two sliding plates 402 for support are slidably connected to the side of the fixed plate 4 away from the rust removal wheel 307. A second drive motor 403 for providing stable driving force is installed on the side of the two sliding plates 402 away from the fixed plate 4. The output shaft of the second drive motor 403 is connected to the end of the rotating shaft 306 through a coupling. After the second drive motor 403 is started, its output shaft drives the rotating shaft 306 to rotate through the coupling. The rotating shaft 306 drives the outer circumferential rust removal wheel 307 to rotate at high speed, forming the power for rust removal operation. Since the slide plate 402 is slidably connected to the side of the fixed plate 4, and the end of the rotating shaft 306 is slidably fitted in the sliding groove 401 of the fixed plate 4, when the moving hollow column 302 drives the support block 305 and the rotating shaft 306 to move, the slide plate 402 slides synchronously with the rotating shaft 306 to ensure the stable rotation of the rotating shaft 306; the elastic force of the spring 303 is transmitted to the rotating shaft 306 through the moving disc 304, the moving hollow column 302, and the support block 305, so that the rust removal wheel 307 adaptively fits the upper and lower surfaces of the steel plate to achieve synchronous rust removal operation.

[0029] A conveying roller 101 for conveying steel plates is installed on the top of the support platform 1. A vertical support 102 for support is fixedly installed on the side of the conveying roller 101. A pressing roller 103 for positioning the steel plates is movably connected to the side of the vertical support 102. A first drive motor 104 for providing driving force is installed at the bottom of the support platform 1. The output shaft of the first drive motor 104 is connected to a belt drive unit 105 through a coupling. An extrusion conveying roller group 106 for increasing the conveying and positioning capability is installed at the output end of the belt drive unit 105. After the first drive motor 104 is started, its output shaft drives the belt drive unit 105 to rotate through the coupling. The belt drive unit 105 drives the extrusion conveying roller group 106 and the conveying roller 101 to rotate synchronously, forming the power for conveying steel plates. After the steel plate is placed on the conveyor roller 101, the pressing roller 103 on the side of the vertical support 102 positions and presses the top of the steel plate. The extrusion conveyor roller group 106 extrudes and positions the steel plate from both sides to prevent deviation and slippage during the conveying process. Under the synergistic action of the conveyor roller 101 and the extrusion conveyor roller group 106, the steel plate is smoothly conveyed to the direction of the rust removal wheel 307. The surface rust is removed by the high-speed rotating rust removal wheel 307, realizing continuous rust removal operation.

[0030] To ensure the stable and efficient operation of the steel plate surface rust removal device, protective measures should be formulated from five dimensions: environmental control, maintenance, material compatibility, component calibration, and standardized operation. These measures aim to mitigate the impact of various factors on the normal operation of the equipment. Specifically, regarding environmental control, the two core hazards of dust and moisture need to be addressed. Rust dust generated by the high-speed rotation of the rust removal wheel 307 during rust removal operations can easily penetrate sliding structures such as the circular groove 201, guide groove 301, and sliding groove 401. It also adheres to the surfaces of the opposing threaded column 202 and the rotating shaft 306, leading to component jamming or accelerated wear. A sealed dust cover should be installed in the working area of ​​the rust removal wheel 307, and a negative pressure dust collection device should be used to collect dust in real time. Residual dust on the surfaces of the conveyor roller 101 and the extrusion conveyor roller group 106 should be cleaned regularly to prevent particulate matter from affecting the conveying positioning accuracy. The ambient humidity needs to be controlled below 60%. A humid environment can easily lead to secondary corrosion of steel plates, corrosion failure of spring 303, and short circuits in the electrical components of the first drive motor 104 and the second drive motor 403. Dehumidification equipment needs to be provided in the workshop, and hidden parts such as the bottom of the support platform 1 and the back of the fixing plate 4 should be regularly ventilated and dried to prevent moisture from corroding the components.

[0031] Maintenance and upkeep must be performed precisely according to schedule to ensure stable performance of all components. For rotating components, the lubricating oil levels of the first drive motor 104 and the second drive motor 403 must be checked monthly, and the appropriate type of lubricating oil must be replaced quarterly to prevent motor overheating or decreased transmission efficiency. The belt drive unit 105 must have its belt tension checked weekly, and aged or loose belts must be adjusted or replaced promptly to prevent slippage that could affect the synchronous operation of the conveyor roller 101 and the extrusion conveyor roller group 106. Regarding sliding and threaded structures, the internal threaded moving frame 204 and the opposing threaded column 202, the moving hollow column 302 and the guide groove 301 must be coated with anti-rust grease weekly, and impurities in the threads and grooves must be cleaned to prevent the internal threaded moving frame 204 from jamming during adjustment and the moving hollow column 302 from sliding poorly. The sliding groove 401 and the sliding plate 402 must be cleaned of foreign objects regularly to ensure that the sliding plate 402 slides smoothly and synchronously when the rotating shaft 306 moves. Regarding vulnerable parts, the rust removal wheel 307 needs to be checked for wear weekly based on the workload. When the rust removal teeth become dull or cracks appear, it should be replaced immediately to avoid incomplete rust removal. The spring 303 needs to be tested for elasticity monthly, and springs that have lost their elasticity should be replaced to ensure that it provides stable adaptive thrust through the moving disc 304. The pressing roller 103 needs to be checked for rotational flexibility regularly, and rollers that are stuck or severely worn should be replaced in a timely manner to ensure the positioning effect of the steel plate.

[0032] Material selection must consider both the materials of the device components and the quality of the steel plate pretreatment. Key components should be made of corrosion-resistant, high-strength materials. For example, the rotating shaft 306 should be made of stainless steel, while the support block 305, fixing frame 3, and adjusting frame 2 should be made of high-strength alloy steel to prevent deformation or damage after prolonged stress or contact with rust dust. The rust-removing wheel 307 requires the selection of appropriate abrasives based on the steel plate material. Wear-resistant diamond abrasive wheels should be used for high-strength steel plates, while corundum abrasive wheels should be used for ordinary steel plates to prevent incompatibility between the abrasive and the steel plate, which could lead to low rust removal efficiency or scratches on the steel plate surface. Before feeding, the steel plate must be pretreated to remove large pieces of welding slag, oil, and other impurities from the surface. This prevents hard impurities from impacting the rust-removing wheel 307 and causing damage to the roller body, while also reducing oil adhesion to the surface of the conveyor roller 101 and its impact on conveying friction.

[0033] Component alignment and calibration are crucial for ensuring coordinated equipment operation. During installation and maintenance, it is essential to ensure precise thread engagement between the internal threaded moving frame 204 and the opposing threaded column 202, without slippage or misalignment. When rotating the handle 205, the synchronous movement of the upper and lower sets of internal threaded moving frames 204 must be verified to prevent imbalance in the spacing adjustment of the rust removal wheel 307. The sliding clearance between the moving hollow column 302 and the guide groove 301 must be maintained between 0.1-0.3mm. Excessive clearance can cause the support block 305 to wobble, while insufficient clearance can cause jamming. Fine-tuning with shims is necessary to ensure proper fit. The parallelism of the conveying roller 101 and the extrusion conveying roller group 106 must be calibrated to ensure synchronous rotation. Simultaneously, the height of the vertical support 102 and the pressing roller 103 should be adjusted to ensure moderate pressure from the pressing roller 103 on the steel plate, avoiding both excessive pressure that could deform the steel plate and insufficient pressure that could affect the positioning effect. The rust removal system must ensure that the axes of the upper and lower rust removal wheels 307 are parallel, and that the coaxiality error between the rotating shaft 306 and the output shaft of the second drive motor 403 is controlled within the allowable range, so as to avoid uneven rust removal of the steel plate or increased vibration of the components caused by the eccentric operation of the rust removal wheel 307.

[0034] Personnel must strictly follow the standardized procedures during operation to avoid human error affecting equipment operation. Before operation, operators must check the tightness of all component connections, confirming that the rotating handle 205, connecting rod 206, support block 305, etc., are not loose, and that the wiring of the first drive motor 104 and the second drive motor 403 is secure. Adjust the initial spacing of the rust-removing wheels 307 by rotating the handle 205 according to the steel plate thickness, ensuring that the spacing is slightly smaller than the steel plate thickness so that the spring 303 can provide effective contact thrust. Do not rotate the handle forcefully, as this may damage the opposing threaded column 202 or the internal thread moving frame 204. During operation, the steel plate conveying status must be monitored in real time. If the steel plate is found to be off-center, adjust the positioning accuracy of the extrusion conveyor roller group 106 in a timely manner to prevent the steel plate from hitting the rust-removing wheels 307 or getting stuck between the conveyor roller 101 and the extrusion conveyor roller group 106. Do not touch the high-speed rotating rust-removing wheels 307 and the rotating shaft 306 while the equipment is running to avoid safety accidents. After operation, the power must be turned off, dust and debris on the surface of the equipment must be cleaned, the operating status of the components must be recorded, and any abnormalities must be stopped and repaired in time. It is forbidden to operate the equipment with faults.

[0035] Through the above multi-dimensional protection measures, adverse effects from the environment, maintenance, materials, coordination and operation can be effectively avoided, ensuring that core components such as support platform 1, adjustment frame 2, fixed frame 3, and fixed plate 4 work together stably, and key actuators such as conveyor roller 101 and rust removal wheel 307 continue to perform at their best, ensuring that the device can achieve continuous and adaptive rust removal operations in a long-term and efficient manner.

[0036] Working principle

[0037] In use, the first drive motor 104 at the bottom of the support platform 1 starts, and the output shaft drives the belt drive unit 105 via the coupling, which in turn drives the extrusion conveyor roller group 106 to rotate synchronously with the conveyor roller 101 at the top of the support platform 1, forming the power for steel plate conveying. After the steel plate is placed on the conveyor roller 101, the pressing roller 103 on the side of the vertical bracket 102 positions and presses the top of the steel plate, and the extrusion conveyor roller group 106 extrudes and positions it from both sides to prevent deviation and slippage during conveying. Under the combined action of the two, the steel plate is smoothly conveyed towards the rust removal wheel 307. Rotating the handle 205 of the adjusting frame 2 can drive the rotating column 203 and the opposing threaded columns 202 at both ends to rotate synchronously. Because the internal threaded moving frame 204 is threadedly connected to the opposing threaded columns 202 and slides symmetrically in the circular slide groove 201, the two sets of internal threaded moving frames 204 move vertically in opposite directions along the circular slide groove 201. Through the connecting rod 206, the moving hollow column 302 slides in the guide circular groove 301 of the fixed frame 3, adjusting the initial distance between the upper and lower sets of rust-removing wheels 307 to adapt to steel plates of different thicknesses. After the second drive motor 403 on the side of the fixed plate 4 is started, the output shaft drives the rotating shaft 306 to rotate at high speed through the coupling, thereby driving the outer circumferential rust-removing wheels 307 to rotate and generate rust-removing power. Since the slide plate 402 is slidably connected to the side of the fixed plate 4, and the end of the rotating shaft 306 is slidably fitted into the sliding groove 401, when the moving hollow column 302 drives the support block 305 and the rotating shaft 306 to move, the slide plate 402 slides synchronously, ensuring the stable rotation of the rotating shaft 306. The spring 303 inside the moving hollow column 302 provides adaptive thrust through the moving disk 304, which is transmitted to the rotating shaft 306 through the moving hollow column 302 and the support block 305, so that the rust removal wheel 307 is in close contact with the upper and lower surfaces of the steel plate. During the continuous conveying of the steel plate, the high-speed rotating rust removal wheel 307 simultaneously removes rust from the upper and lower surfaces, realizing continuous and adaptive rust removal operation.
