Description

Technical Field

[0001] This invention belongs to the field of metal sheet processing technology and relates to a device for treating surface defects of hot-rolled pickled steel sheets. Background Technology

[0002] Hot-rolled pickled steel sheets, with their excellent surface quality, high dimensional accuracy, and good stamping performance, are widely used in various industrial fields such as automobile manufacturing, construction machinery, home appliance production, and steel structure processing. During the production and processing of hot-rolled pickled steel sheets, the surface of the sheets is prone to defects such as deep pits and dents due to the influence of rolling process, pickling process, and conveying and transfer processes. The edges are also prone to residual defects such as burrs, oxide scale, and shear marks. These surface and edge defects can seriously affect the quality of subsequent processing, such as causing stress concentration and cracking during stamping, reducing coating adhesion, and even affecting the structural strength and service life of the final product. Therefore, it is necessary to carry out targeted cleaning and treatment of surface and edge defects of hot-rolled pickled steel sheets.

[0003] Currently, existing technologies mainly employ rigid grinding mechanisms, which use motors to drive grinding wheels to directly contact and grind the surface of the board. However, the grinding force of rigid grinding mechanisms is difficult to control precisely. When cleaning deep pit defects, it is very easy to cause secondary damage such as scratches and indentations to the surrounding normal board surface. It is especially unsuitable for hot-rolled pickled boards with high surface quality requirements.

[0004] The existing edge cleaning equipment has insufficient reliability in adhering the grinding wheel to the edge of the board. Most equipment adopts a fixed spacing installation structure, which cannot adapt to slight positional deviations during the board conveying process. This can easily lead to problems such as the grinding wheel detaching from the edge of the board, resulting in missed cleaning, or excessive squeezing of the board, causing edge deformation.

[0005] Therefore, we propose a surface defect treatment device for hot-rolled pickled steel plates to solve the problems mentioned above. Summary of the Invention

[0006] In view of this, in order to solve the above problems, the present invention provides a device for treating surface defects of hot-rolled pickled steel plates.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for treating surface defects of hot-rolled pickled steel plates, comprising:

[0008] Mainframe;

[0009] A material conveying module is mounted on the main frame and is used to convey sheet metal along the conveying direction;

[0010] The deep pit cleaning module is installed on the main frame and located above the conveying path of the material conveying module;

[0011] The deep pit cleaning module includes a drive motor III, a flange connecting plate driven to rotate by the drive motor III, a plurality of traction steel cables with one end fixedly connected to the bottom of the flange connecting plate, and a grinding head fixedly connected to the other end of each of the traction steel cables.

[0012] When the drive motor III drives the flange connecting plate to rotate, centrifugal force is used to drive each of the grinding heads to unfold outward and rotate at high speed to perform flexible grinding and cleaning on the upper surface of the plate.

[0013] An edge cleaning mechanism is provided on the main frame corresponding to the side of the plate;

[0014] The edge cleaning mechanism includes a drive motor IV, an edge grinding wheel driven to rotate by the drive motor IV, and an elastic support assembly;

[0015] The elastic support assembly is used to apply a biasing force to the edge grinding wheel so that it always abuts against the side of the plate.

[0016] As a further improvement to the above technical solution:

[0017] The material conveying module includes two drive shafts rotatably mounted on the main frame, drive sprockets fixed on each drive shaft, drive chains tensioned on the corresponding drive sprockets, and multiple connecting base plates fixedly connected between the two drive chains.

[0018] A buffer rubber pad is embedded on the top surface of the connecting substrate.

[0019] The deep pit cleaning module also includes multiple support columns fixed on the main frame and a lifting adjustment plate that can be lifted and lowered and sleeved on the support columns;

[0020] The drive motor III is fixedly installed on the top of the lifting adjustment plate; a power drive shaft is rotatably arranged on the lifting adjustment plate, the flange connecting plate is fixedly connected to the bottom end of the power drive shaft, and the output end of the drive motor III is connected to the power drive shaft through a synchronous belt transmission mechanism.

[0021] The top ends of the plurality of supporting columns are fixedly connected to a top mounting plate, and the top mounting plate is provided with an internal threaded sleeve;

[0022] The deep pit cleaning module also includes a lifting adjustment screw, which is threaded into the internal threaded sleeve, and its bottom end is rotatably connected to the lifting adjustment plate.

[0023] It also includes sliding guide rod I and retaining ring;

[0024] The sliding guide rod I passes through the power drive shaft and the flange connecting plate and is slidably disposed therein, and its bottom end is connected to the retaining ring through multiple auxiliary support rods;

[0025] Multiple traction cables are threaded through the retaining ring;

[0026] The power drive shaft is also equipped with fastening screws for locking the sliding guide rod I.

[0027] It also includes two sets of bearing housings II and material holding rollers;

[0028] The two sets of bearing seats II are fixed on the main frame and are respectively located on both sides of the material conveying module. The material holding roller is rotatably arranged between the two sets of bearing seats II for pressing the plate from above.

[0029] The edge cleaning mechanism is mounted on the bearing housing II;

[0030] It also includes a fixed support arm, an adjusting rod, and two hinged connecting rods;

[0031] The fixed support arm is fixed to the bearing seat II;

[0032] The two ends of the two hinged links are respectively hinged to the fixed support arm and the adjusting rod, so that the adjusting rod can swing relative to the fixed support arm;

[0033] The edge grinding wheel is rotatably mounted on the component mounting seat at the end of the adjusting rod via a component mounting shaft;

[0034] The drive motor IV is fixed on the adjusting rod and connected to the component mounting shaft via a synchronous belt transmission mechanism.

[0035] The component mounting base is also rotatably equipped with two positioning guide rollers, which are respectively located on both sides of the edge grinding wheel to clamp and guide the edge of the plate.

[0036] The elastic support assembly includes a sliding guide rod II, a spring, and a limiting ring;

[0037] The sliding guide rod II is slidably inserted into the adjusting rod, and one end of it is provided with a guide ball and abuts against the fixed support arm. The limiting ring is fixed to the sliding guide rod II.

[0038] The spring is sleeved outside the sliding guide rod II, with its two ends abutting against the adjusting rod and the limiting ring, respectively.

[0039] The outer circumferential surface of the edge grinding wheel is provided with an annular groove that matches the thickness of the plate.

[0040] The beneficial effects of this invention are as follows:

[0041] 1. The hot-rolled pickled steel plate surface defect treatment equipment disclosed in this invention integrates a material conveying module, a deep pit cleaning module, and a workpiece edge cleaning mechanism. It can simultaneously complete the flexible cleaning of deep pit defects on the upper surface and the precise cleaning of edge burrs and oxide scale during the continuous conveying of the steel plate. It eliminates the need for multiple processing steps in sections, effectively shortens the overall treatment cycle of surface defects of hot-rolled pickled steel plates, improves continuous operation capability, and adapts to the needs of industrial mass production. Compared with traditional segmented processing equipment, it avoids the cumbersome process of multiple positioning and transfer of steel plates, reduces the time consumption of process connection and positioning error, and further improves production efficiency.

[0042] 2. The hot-rolled pickled plate surface defect treatment equipment disclosed in this invention uses a material conveying module to drive the connecting substrate and buffer rubber pad through a transmission sprocket and transmission chain to realize the conveying of the plate. The buffer rubber pad can avoid damage caused by hard contact with the lower surface of the plate. At the same time, in conjunction with the rotation and clamping action of the material holding roller, it can effectively prevent the plate from deviating or jumping during the conveying process. The positioning guide roller in the edge cleaning mechanism can continuously guide the edge of the plate to ensure that the edge of the plate is always precisely aligned with the edge grinding wheel. By using the physical bias of the spring force and the physical limit of the roller, the grinding module is "locked" to the edge of the steel plate. No matter how the width of the steel plate changes or serpentine deviation occurs, the guide roller will push the entire grinding module to move horizontally synchronously, realizing the precise removal of edge defects by "blind operation".

[0043] 3. The hot-rolled pickled steel plate surface defect treatment equipment disclosed in this invention uses a traction steel cable to connect the flange connecting plate and the grinding head. The flange connecting plate is rotated by the drive motor III, and the grinding head is driven to rotate at high speed and expand outward by centrifugal force, so as to realize the flexible cleaning of deep pit defects on the surface of the plate. Compared with the rigid grinding structure, this flexible cleaning method can be precisely applied to the deep pit defect area, while avoiding secondary damage such as scratches and indentations to the normal surface of the plate. It is especially suitable for the treatment of hot-rolled pickled steel plates with high surface quality requirements, effectively ensuring the integrity and surface quality of the plate body.

[0044] 4. The hot-rolled pickled steel plate surface defect treatment equipment disclosed in this invention features a deep pit cleaning module. The height of the lifting adjustment plate can be adjusted via a lifting adjustment screw, thereby adjusting the distance between the grinding head and the upper surface of the plate to adapt to the cleaning needs of deep pit defects of different depths. The height of the retaining ring can be adjusted via the sliding guide rod I to adjust the tension of the traction steel cable, ensuring cleaning stability. The spring force of the elastic support component can adapt to different contact force requirements. The adjustability of the multi-structure allows the equipment to adapt to the treatment of hot-rolled pickled steel plates of different specifications and defect types, significantly improving the versatility and applicability of the equipment and reducing the equipment investment costs for enterprises for different types of steel plates.

[0045] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0058] Example 1

[0059] like Figures 1-7 As shown, a surface defect treatment device for hot-rolled pickled steel sheets is used to treat deep pit defects, edge burrs, oxide scale, and other defects on the surface of hot-rolled pickled steel sheets. It can realize continuous conveying of the sheets and synchronous defect treatment.

[0060] The equipment includes a main frame 1, which is formed by welding profiles. The top has evenly distributed mounting holes for precise fixing of various components, and the bottom has an anti-slip structure to enhance the stability of the equipment. A material conveying module 3 is mounted on the top of the main frame 1, and a drive motor I4 is bolted to it. The drive motor I4 is connected to the main frame 1 via a motor mount, and a locating pin is provided on the connection surface between the motor mount and the main frame 1 to ensure accurate installation of the drive motor I4. The drive motor I4 drives the material conveying module 3 to move the conveyed material. An external protective shell 2 is also bolted to the top of the main frame 1. Figure 1 The outer protective shell 2 (which is half of the whole) surrounds the material conveying module 3. A transparent observation window is provided on one side for operators to easily view the internal working status, and a chip discharge port is provided at the bottom for easy collection and discharge of flying debris. The material conveying module 3 is located inside the outer protective shell 2, which prevents the spread of flying debris generated during the cleaning process and simultaneously collects the debris.

[0061] Two sets of bearing seats II5 are bolted to the top of the main frame 1. These two sets of bearing seats II5 are located on either side of the material conveying module 3. Each bearing seat II5 contains a rolling bearing. A material holding roller 6 is rotatably mounted between the two sets of bearing seats II5. Both ends of the material holding roller 6 pass through the inner rings of the rolling bearings in the two sets of bearing seats II5, with an interference fit to ensure smooth rotation. Two drive motors II7 are fixed to the top of the main frame 1 via a motor bracket. The motor bracket is bolted to the main frame 1. The output end of the drive motor II7 is connected to one end of the material holding roller 6 via a synchronous belt and synchronous pulley. The synchronous pulleys are fixed to the output shaft of the drive motor II7 and the end of the material holding roller 6 via flat keys. The synchronous belt is tensioned and fitted onto the two synchronous pulleys to ensure stable power transmission. The drive motor II7 drives the material holding roller 6 to rotate, and the rotation of the material holding roller 6, in conjunction with the material conveying module 3, achieves stable conveying of the sheet material.

[0062] A deep pit cleaning module 8 is installed on the top of the main frame 1, between the two material holding rollers 6. The deep pit cleaning module 8 includes a drive motor Ⅲ 87, a flange connecting plate 812, multiple traction steel cables 813, and a grinding head 810, as well as multiple support columns 81. The support columns 81 are fixed in the mounting holes on the top of the main frame 1 by bolts. The multiple support columns 81 are symmetrically distributed. A lifting adjustment plate 83 is mounted on the outer wall of the support column 81. The lifting adjustment plate 83 has a guide hole adapted to the support column 81. The inner wall of the guide hole fits against the outer wall of the support column 81 to ensure that the lifting adjustment plate 83 rises and falls smoothly without deviation. A dustproof sealing ring is embedded in the inner wall of the guide hole of the lifting adjustment plate 83. The dustproof sealing ring fits tightly against the outer wall of the support column 81 to prevent dust from entering the sliding mating surface. The drive motor Ⅲ87 is fixed to the top of the lifting adjustment plate 83 by a motor mount. The motor mount and the lifting adjustment plate 83 are connected by bolts. A rolling bearing is installed through the top of the lifting adjustment plate 83. The outer ring of the rolling bearing is interference-fitted with the lifting adjustment plate 83, and the inner ring of the rolling bearing is interference-fitted with the power drive shaft 89, so as to realize the rotational installation of the power drive shaft 89 on the lifting adjustment plate 83. The flange connecting plate 812 is fixed to the bottom end of the power drive shaft 89 by bolts. The top ends of multiple traction steel cables 813 are fixed to the bottom of the flange connecting plate 812 by rope clamps. The rope clamps tighten the traction steel cables 813 to prevent them from falling off. The grinding head 810 is fixed to the bottom end of the traction steel cables 813 by welding. The output end of the drive motor III 87 is connected to the power drive shaft 89 through a synchronous belt and a synchronous pulley. The synchronous pulley is fixed to the output shaft of the drive motor III 87 and the top end of the power drive shaft 89 by a flat key. The synchronous belt tensioning sleeve is fitted on the two synchronous pulleys. The drive motor III 87 can drive the flange connecting plate 812 to rotate, and use centrifugal force to drive the traction steel cables 813 and the grinding head 810 to rotate. The grinding head 810 uses a grinding block with a certain weight and hardness. When the drive motor Ⅲ87 drives at high speed, the centrifugal force enables the grinding head 810 to obtain sufficient radial speed and kinetic energy. When it is thrown to contact the surface of the plate, its kinetic energy is converted into impact and grinding action on the surface protrusions such as defect edges. At the same time, due to the flexible connection of the traction steel cable 813, the grinding head is allowed to yield in the normal direction, avoiding excessive rigid pressure damage to the flat substrate, thereby achieving a flexible cleaning effect of 'replacing grinding with beating'.

[0063] Multiple supporting columns 81 are bolted to the top of a common top mounting plate 82. An internally threaded sleeve 84 is welded through the top mounting plate 82. A lifting and adjusting screw 85 is threadedly connected inside the internally threaded sleeve 84. A telescopic dust cover is fitted over the lifting and adjusting screw 85, with both ends fixedly connected to the top mounting plate 82 and the lifting and adjusting plate 83, respectively, to prevent dust from entering the threaded mating surface. The bottom end of the lifting and adjusting screw 85 is rotatably connected to the lifting and adjusting plate 83 via a thrust bearing. The thrust bearing is installed in a groove at the top of the lifting and adjusting plate 83 and can withstand the axial force transmitted by the lifting and adjusting screw 85, ensuring that the lifting and adjusting plate 83 only moves up and down and does not rotate with the lifting and adjusting screw 85. A locking nut ring 86 is threaded onto the outer wall of the lifting and adjusting screw 85. The bottom end of the locking nut ring 86 abuts against the top end of the internally threaded sleeve 84. After the position of the lifting and adjusting plate 83 is adjusted, tightening the locking nut ring 86 locks the lifting and adjusting screw 85, preventing the lifting and adjusting plate 83 from shifting during operation.

[0064] A sliding guide rod I88 is slidably mounted through the center of the power drive shaft 89 and the flange connecting plate 812. The contact surfaces of the sliding guide rod I88 with the power drive shaft 89 and the flange connecting plate 812 are smooth, ensuring smooth sliding. Multiple auxiliary support rods 814 are welded to the outer wall of the bottom end of the sliding guide rod I88. These auxiliary support rods 814 are radially distributed, and their outer ends are all welded to the same retaining ring 815. Multiple traction cables 813 are located inside the retaining ring 815. The retaining ring 815 limits the swing range of the traction cables 813 during rotation, preventing them from tangling. A threaded hole is drilled through the outer wall of the power drive shaft 89, and a fastening screw 811 is threaded into the threaded hole. One end of the fastening screw 811 abuts against the outer wall of the sliding guide rod I88. After adjusting the position of the sliding guide rod I88, tightening the fastening screw 811 secures the sliding guide rod I88.

[0065] An edge cleaning mechanism 9 is installed on each of the two bearing seats II5 on one side. The edge cleaning mechanism 9 includes a drive motor IV 97, an edge grinding wheel 95, an elastic support assembly, and a fixed support arm 91. The fixed support arm 91 is fixed to one side of the bearing seat II5 by bolts. An adjusting rod 93 is provided on one side of the fixed support arm 91. The top of both the fixed support arm 91 and the adjusting rod 93 are provided with pin holes. The two ends of the two hinged connecting rods 92 are respectively connected to the pin holes of the fixed support arm 91 and the adjusting rod 93 through pins. The two ends of the pins are limited by cotter pins to prevent the pins from falling off, so as to realize the rotational connection between the hinged connecting rods 92, the fixed support arm 91, and the adjusting rod 93, forming a quadrilateral structure. One end of the adjusting rod 93 is welded with a component mounting base 94. A rolling bearing is installed through the top of the component mounting base 94. The outer ring of the rolling bearing is interference-fitted with the component mounting base 94, and the inner ring is interference-fitted with the component mounting shaft 910. The edge grinding wheel 95 is fixedly sleeved on the component mounting shaft 910 by a locking nut. The locking nut is tightened at the bottom end of the component mounting shaft 910 to prevent the edge grinding wheel 95 from moving axially. The outer wall of the edge grinding wheel 95 has an annular groove 951. The annular groove 951 is adapted to the thickness of the plate. The edge of the plate can be embedded in the annular groove 951, so that the edge grinding wheel 95 fully fits the edge of the plate, improving the edge cleaning effect. The drive motor Ⅳ97 is fixed to the bottom of the adjusting rod 93 by a motor bracket. The motor bracket is welded to the adjusting rod 93. The output end of the drive motor Ⅳ97 is connected to the component mounting shaft 910 via a synchronous belt and a synchronous pulley. The synchronous pulley is fixed to the output shaft of the drive motor Ⅳ97 and the top of the component mounting shaft 910 by a flat key. The synchronous belt is tensioned and sleeved on the two synchronous pulleys. The top of the adjusting rod 93 and the component mounting shaft 910 are fixed with a protective cover 98 by bolts. The protective cover 98 completely covers the synchronous pulley and the synchronous belt to prevent flying debris from adhering and affecting the transmission, and at the same time prevents the operator from accidentally touching the rotating parts.

[0066] Two fixed mounting shafts 99 are welded through the top of the component mounting base 94. The two fixed mounting shafts 99 are located on both sides of the edge grinding wheel 95. Rolling bearings are fitted on the outer wall of the fixed mounting shafts 99. Positioning guide rollers 96 are installed with interference fit on the outer ring of the rolling bearings. The positioning guide rollers 96 can rotate freely around the fixed mounting shafts 99. When the plate is conveyed, the positioning guide rollers 96 contact the edge of the plate and rotate with the plate, which guides the plate and ensures that the edge of the plate is always aligned with the edge grinding wheel 95.

[0067] The equipment also includes a PLC controller, which is fixedly installed on one side of the main frame 1 and electrically connected to drive motor I4, drive motor II7, drive motor III87, and drive motor IV97 respectively. The PLC controller is used to preset the start-stop sequence and speed parameters of each motor to realize the coordinated operation of the material conveying module 3, material holding roller 6, deep pit cleaning module 8, and edge cleaning mechanism 9. For example, it controls drive motor I4 and drive motor II7 to start conveying the plate synchronously, and after the plate reaches the preset position, drive motor III87 and drive motor IV97 are started to clean defects.

[0068] Example 2

[0069] Reference Figures 1-7 This invention provides a novel technical solution: a surface defect treatment device for hot-rolled pickled steel plates. The elastic support assembly includes a sliding guide rod II 911. An adjusting rod 93 has a through hole inside, through which the sliding guide rod II 911 slides smoothly. The smooth inner wall of the through hole ensures smooth sliding of the sliding guide rod II 911. A dust cover is installed at the through hole end of the adjusting rod 93, covering the outer wall of the sliding guide rod II 911 to prevent dust from entering the through hole. One end of the sliding guide rod II 911 has a ball groove, in which a guide ball 914 is embedded. The ball groove restricts the movement range of the guide ball 914, ensuring that the guide ball 914 can only roll without falling off. A limit ring 913 is welded and fixed to one end of the sliding guide rod II 911. A spring 912 is sleeved on the outer wall of the sliding guide rod II 911. The two ends of the spring 912 abut against the opposite sides of the adjusting rod 93 and the limit ring 913, respectively. Under the elastic force of the spring 912, the guide ball 914 is always in close contact with one side of the fixed support arm 91. Then, the adjusting rod 93 drives the component mounting seat 94 and the edge grinding wheel 95 to apply force towards the edge of the plate, so that the edge grinding wheel 95 is always in contact with the side wall of the plate.

[0070] The material conveying module 3 includes two bearing seats I 31, both of which are fixedly installed on the top of the main frame 1. A transmission shaft 32 is rotatably mounted inside the bearing seat I 31. Two transmission sprockets 33 are fixedly sleeved on the outer wall of the transmission shaft 32. A transmission chain 34 is connected between the two transmission sprockets 33 on the same side. Multiple connecting base plates 35 are fixedly mounted on the two transmission chains 34. A buffer rubber pad 36 is embedded on the top of the connecting base plate 35. The thickness of the buffer rubber pad 36 is set to 3-5mm, and its Shore hardness is 60-70HA. The output end of the drive motor I 4 is connected to one of the transmission shafts 32. After the drive motor I 4 is started, it can drive the transmission shaft 32 to rotate. The transmission shaft 32 drives the transmission sprocket 33 to rotate. The transmission sprocket 33 drives the transmission chain 34 to move. The transmission chain 34 drives the connecting base plate 35 and the buffer rubber pad 36 to move. The buffer rubber pad 36 contacts the lower surface of the plate, thereby realizing the conveying of the plate.

[0071] The rotating parts of this equipment (such as the bearings in bearing housing I 31 and bearing housing II 5) and sliding parts (such as the support column 81 and lifting adjustment plate 83, and the sliding guide rod II 911 and adjustment rod 93) need to be lubricated regularly, once every 500 hours of operation; the transmission chain 34 needs to be cleaned of surface dust and lubricated regularly; the traction steel cable 813 and spring 912 are wear parts and need to be checked for wear regularly. If there are problems such as breakage or loss of elasticity, they should be replaced in time; the chip discharge port at the bottom of the outer protective shell 2 needs to be cleaned regularly to collect metal chips and avoid accumulation that affects the operation of the equipment.

[0072] When surface defect treatment is required on hot-rolled pickled steel sheets, the sheets are placed on the buffer rubber pad 36 of the material conveying module 3, with the buffer rubber pad 36 adhering to the lower surface of the sheet. Drive motor I4 is started, and drive motor I4 drives one of the transmission shafts 32 to rotate via a coupling. The transmission shaft 32 drives the transmission sprocket 33 to rotate, which in turn drives the transmission chain 34 to move. The transmission chain 34 then drives the connecting base plate 35 and the buffer rubber pad 36 to move synchronously, thereby moving the sheet. Simultaneously, drive motor II7 is started, and drive motor II7 drives the material holding roller 6 to rotate via a synchronous belt and synchronous pulley. The material holding roller 6, in conjunction with the buffer rubber pad 36, clamps the sheet, preventing deviation or jumping during conveying. Start the drive motor Ⅲ87. The drive motor Ⅲ87 drives the power drive shaft 89 to rotate via the synchronous belt and synchronous pulley. The power drive shaft 89 drives the flange connecting plate 812 to rotate. The flange connecting plate 812 drives the traction steel cable 813 to rotate. Under the action of centrifugal force, the grinding head 810 rotates at high speed and unfolds outward. When the plate moves to the bottom of the deep pit cleaning module 8, the high-speed rotating grinding head 810 contacts the deep pit defects on the upper surface of the plate and performs flexible cleaning of the deep pit defects to avoid damaging the normal surface of the plate. When the high-speed rotating grinding head 810 cannot completely cover the surface of the plate, the fastening screw 811 can be turned to release the limit on the sliding guide rod Ⅰ88. At this time, the sliding guide rod Ⅰ88 can be moved up and down to adjust until the high-speed rotating grinding head 810 can completely cover the surface of the plate. Then, the fastening screw 811 is tightened. Then, the lifting adjustment screw 85 is turned to drive the lifting adjustment plate 83 to move downward until the high-speed rotating grinding head 810 contacts the plate. Start the drive motor IV97. The drive motor IV97 drives the component mounting shaft 910 to rotate via the synchronous belt and synchronous pulley. The component mounting shaft 910 drives the edge grinding wheel 95 to rotate. Under the elastic force of the elastic support component, the edge grinding wheel 95 is always in contact with the side wall of the plate. When the plate moves, the rotating edge grinding wheel 95 cleans burrs, oxide scale and other defects on the edge of the plate. The positioning guide roller 96 rotates with the plate and continuously guides the plate. The flying debris generated during the cleaning process is blocked by the outer protective shell 2 and falls to the bottom of the shell. It is discharged through the chip discharge port and collected. The operator can check the internal cleaning situation in real time through the observation window of the outer protective shell 2 to ensure the normal operation of the equipment.
