Description

Technical Field

[0001] This invention belongs to the technical field of steel plate processing equipment, and in particular relates to a comprehensive steel plate rust removal device. Background Technology

[0002] Steel plates are used in many fields, and hot-rolled steel plates are generally used. During production, stains and rust inevitably appear on their surface. Therefore, before use, the stains and rust on their surface need to be treated to meet production requirements.

[0003] Existing steel plate rust removal technologies typically employ two methods: roller brushes and flat brushes. Flat brush rust removal usually utilizes the horizontal reciprocating motion of the brush body to remove rust from the steel plate. This method generally only works on the top and bottom surfaces of the steel plate, neglecting the sides. This necessitates additional rust removal mechanisms for the sides, thus affecting the overall rust removal efficiency. Furthermore, flat brush rust removal equipment requires brush replacement after a period of use. Since the brush body and its drive mechanism are usually bolted together, the disassembly and replacement of the brush body is time-consuming, leading to prolonged downtime and further impacting the rust removal efficiency. Therefore, there is an urgent need to research a comprehensive, all-encompassing steel plate rust removal device to address these issues. Summary of the Invention

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1-3As shown, the present invention is a full-coverage steel plate rust removal device, including a pair of parallel crossbeams 1; the two crossbeams 1 are connected by multiple conveying rollers 2; a reciprocating drive mechanism 3 is installed between the two crossbeams 1; a pair of movable columns 4 parallel to the conveying rollers 2 are connected to the reciprocating drive mechanism 3; the reciprocating drive mechanism 3 can drive the two movable columns 4 to move relative to each other; one movable column 4 is located above the conveying roller 2; the other movable column 4 is located between any two adjacent conveying rollers 2; a bearing strip 5 parallel to the conveying roller 2 is attached to the adjacent two sides of the two movable columns 4; both ends of the bearing strip 5 are integrally formed with flanges 501; the bearing strip 5 and the two flanges 501 form a "]" shaped structure; multiple conventional brush bristles 502 in the art are vertically fixed on the side of the bearing strip 5 away from the movable column 4 and the opposite inner sides of the two flanges 501. In use, the steel plate is placed horizontally on the conveying roller 2 for conveying. The reciprocating drive mechanism 3 drives the two movable columns 4 to move relative to each other, causing the bearing strip 5 at the bottom of one movable column 4 to brush the upper surface and side of the steel plate, and the bearing strip 5 at the top of the other movable column 4 to brush the lower surface and side of the steel plate. This achieves full-coverage rust removal treatment of the steel plate and effectively improves the rust removal efficiency of the steel plate.

[0033] Example 2: Based on Example 1, as follows Figures 3-6As shown, the reciprocating drive mechanism 3 includes a power assembly 301 mounted below the conveyor roller 2; a reciprocating push-pull assembly 302 is horizontally connected to the power assembly 301; the reciprocating push-pull assembly 302 is mounted on two crossbeams 1; a pair of lifting assemblies 303 are vertically connected to the reciprocating push-pull assembly 302; a rotating assembly 304 is horizontally connected to each of the two lifting assemblies 303; the two rotating assemblies 304 are respectively connected to two movable columns 4; the power assembly 301 includes a drive shaft 3011 arranged parallel to the conveyor roller 2; a first mounting block 3012 is rotatably connected to both ends of the drive shaft 3011; the two first mounting blocks 3012 are respectively welded to the lower surface of the two crossbeams 1; a first mounting block 3012... The lower horizontal bolt of 12 is connected to a first servo motor 3013; the output shaft of the first servo motor 3013 is keyed to a first pulley 3014; the first pulley 3014 is connected to a second pulley 3015 via a synchronous belt drive; the second pulley 3015 is keyed to the outer periphery of the drive shaft 3011; both ends of the drive shaft 3011 are keyed to third pulleys 3016; the two third pulleys 3016 are respectively connected to fourth pulleys 3017 via synchronous belt drives; the two fourth pulleys 3017 are respectively keyed to the outer periphery of a pair of coaxially arranged drive shafts 3018; a second mounting block 3019 is rotatably connected to each of the two drive shafts 3018; the two second mounting blocks 3019 are respectively... Welded to the upper surfaces of the two crossbeams 1; the reciprocating push-pull assembly 302 includes a pair of guide rails 3021 respectively horizontally bolted to the opposite outer surfaces of the two crossbeams 1 and a pair of gears 3022 respectively keyed to the outer periphery of the two drive shafts 3018; both guide rails 3021 are arranged parallel to the crossbeams 1; a pair of sliders 3023 are slidably connected to each of the two guide rails 3021; ​​mounting plates 3024 are vertically bolted to each of the two pairs of sliders 3023; racks 3025 parallel to the guide rails 3021 are horizontally welded to each of the two pairs of mounting plates 3024; the two pairs of racks 3025 mesh with the two gears 3022 respectively; the lifting assembly 303 includes a pair of conventional one-way pneumatic... Cylinder 3031; Two one-way cylinders 3031 are vertically bolted to mounting plates 3024 on two guide rails 3021 facing the same end; the output ends of the two one-way cylinders 3031 are vertically bolted to L-shaped seats 3032; the rotating assembly 304 includes a pair of rotating shafts 3041 that are vertically bolted to the two end faces of the movable column 4; the two rotating shafts 3041 are rotatably connected to the vertical sections of the two L-shaped seats 3032 of the lifting assembly 303; one end of one rotating shaft 3041 is coaxially fixed to the output shaft of a second servo motor 3042 through a conventional coupling in the art; the second servo motor 3042 is horizontally bolted to the vertical section of an L-shaped seat 3032.In use, the first servo motor 3013 drives the first pulley 3014 to reciprocate in both forward and reverse directions. This causes the first pulley 3014 to drive the gear 3022 to reciprocate in both forward and reverse directions via the second pulley 3015, drive shaft 3011, third pulley 3016, fourth pulley 3017, and transmission shaft 3018. The gear 3022 then drives the two movable columns 4 to move relative to each other via the rack 3025, mounting plate 3024, lifting assembly 303, and rotating assembly 304. This allows the brush bristles 502 to act on the surface of the steel plate, effectively ensuring the rust removal efficiency of the steel plate.

[0034] Among them, such as Figures 5-8 As shown, the movable column 4 has a square cross-section perpendicular to its length; the movable column 4 has a receiving chamber 402; each of the four sides of the movable column 4 has multiple through holes 401 arranged side by side along its length, communicating with the receiving chamber 402; a positioning mechanism 6 is installed in the receiving chamber 402; the positioning mechanism 6 includes a mounting column 601 horizontally bolted to the receiving chamber 402 and multiple sets of iron columns 602 that slide through the through holes 401 on the movable column 4; the mounting column 601 is arranged parallel to the movable column 4; each of the four sides of the mounting column 601 is bolted to an electromagnet 603 corresponding to the iron column 602; one end of the iron column 602 is welded to the bearing strip 5; the other end of the iron column 602 can be attracted to the electromagnet 603. When it is necessary to replace the bearing strip 5, first stop the power unit 301, then drive the L-shaped seat 3032 to move away from the crossbeam 1 through the one-way cylinder 3031. Then, drive the movable column 4 to rotate 90° through the second servo motor 3042 via the rotating shaft 3041. Then, de-energize the electromagnet 603 corresponding to the iron column 602 on the bearing strip 5. Finally, manually pull out the bearing strip 5 to remove it from the movable column 4. Then, insert the iron column 602 on the new bearing strip 5 into the through hole 401 and make the iron column 602 abut against the electromagnet 603. Then, energize the electromagnet 603 to make the iron column 602 attract to the electromagnet 603, thereby locking the position of the new bearing strip 5. This not only facilitates the replacement of the bearing strip 5, but also effectively improves the replacement efficiency of the bearing strip 5, while reducing the downtime of the entire device and ensuring the rust removal efficiency of the steel plate.

[0035] Example 3: Based on Example 2, as follows Figures 1-2 and Figure 9As shown, each of the two movable columns 4 is equipped with a loading and unloading mechanism 7 on one side; the loading and unloading mechanism 7 includes a bidirectional moving assembly 701; a pair of receiving frames 702 parallel to the conveying roller 2 are horizontally connected to the bidirectional moving assembly 701; the bidirectional moving assembly 701 can drive the two receiving frames 702 to move relative to each other; the two receiving frames 702 are located on opposite sides of the movable column 4; both receiving frames 702 have a "[" shaped structure, and the side openings of the receiving frames 702 face the movable column 4; the length of the receiving frame 702 is slightly shorter than the length of the bearing strip 5, that is, the bearing strip 5 is slidably mounted on the receiving frame 702. When placed within frame 702, the side of the two flanges 501 furthest from the bearing strip 5 abuts against the vertical section of the receiving frame 702, but the two flanges 501 slightly protrude from both ends of the receiving frame 702. This is to facilitate clamping the bearing strip 5. One receiving frame 702 is used to place the bearing strip 5 removed from the movable column 4; the other receiving frame 702 is used to place the bearing strip 5 to be installed on the movable column 4. Both receiving frames 702 are equipped with clamping components 703 for limiting the position of the bearing strip 5. The bidirectional moving component 701 includes a support plate parallel to the conveying roller 2. Support strip 7011; both ends of support strip 7011 are vertically welded with columns 7012; the two columns 7012 are respectively welded to the two crossbeams 1; a third servo motor 7013 is horizontally bolted to one side of support strip 7011; the output shaft of the third servo motor 7013 passes through support strip 7011 and is coaxially fixed to a bidirectional screw 7014 perpendicular to the conveyor roller 2 through a conventional coupling in the art; both threaded sections of the bidirectional screw 7014 are threadedly fitted with transmission blocks 7015; the two transmission blocks 7015 are respectively bolted to the two receiving frames. At the upper part of 702, a guide rod 7016 is arranged parallel above the bidirectional screw 7014; one end of the guide rod 7016 is bolted to the support strip 7011; the support strip 7011 slides through the two transmission blocks 7015; the clamping assembly 703 includes a bidirectional cylinder 7031 that is horizontally bolted to the vertical section of the receiving frame 702; both output ends of the bidirectional cylinder 7031 are coaxially fixed with pull rods 7032; the ends of the two pull rods 7032 away from the bidirectional cylinder 7031 are bolted with clamping pieces 7033 that are parallel to the flange 501.In use, the new support plate 5 is first placed in a receiving frame 702, and the support plate 5 is clamped by the clamping piece 7033 on the receiving frame 702. After the second servo motor 3042 drives the movable column 4 to rotate 90° via the rotating shaft 3041, the old support plate 5 on the movable column 4 is moved towards the other receiving frame 702. Then, the third servo motor 7013 drives the bidirectional screw 7014 to rotate, causing the two receiving frames 702 to move closer to the movable column 4. This achieves the sliding fit of the old support plate 5 in the other receiving frame 702 and the insertion of the iron column 602 on the new support plate 5 into the through hole 401 and the corresponding electromagnetic... When the iron 603 comes into contact with each other, the electromagnet corresponding to the old support plate 5 is de-energized and the electromagnet corresponding to the new support plate 5 is energized. The clamping piece 7033 on another receiving frame 702 clamps the old support plate 5 and the clamping piece 7033 on one receiving frame 702 releases the new support plate 5. Then, the double screw 7014 drives the two receiving frames 702 to reset, thereby removing the old support plate 5 from the movable column 4 and installing the new support plate 5 on the movable column 4. This realizes the automated loading and unloading of the support plate 5, further shortens the replacement time of the support plate 5, and ensures the overall effectiveness of the device.
