Description

Technical Field

[0001] This application relates to the technical field of grinding equipment, and in particular to a grinding and cleaning device for color steel plate processing. Background Technology

[0002] Color-coated steel sheet refers to pre-painted steel sheet, which is produced on a continuous mill using cold-rolled strip steel or galvanized strip steel (electroplated and hot-dip galvanized) as the substrate. After surface pretreatment (degreasing and chemical treatment), one or more layers of liquid coating are applied by roller coating, followed by baking and cooling to obtain the sheet material.

[0003] Before painting, the surface of the color steel plate usually needs to be sanded to remove burrs and defects. Then, the paint is applied to make the paint adhere more firmly to the color steel plate.

[0004] Currently, when grinding, a grinding machine is usually used to directly grind the upper and lower side walls of the color steel plate. However, the grinding roller of the grinding machine is a single piece, while the length and width of the color steel plate vary. When grinding color steel plates of different sizes, the contact position between the grinding roller and the color steel plate is also different. This can result in the upper part of the grinding roller being worn while the other part remains unworn. When the grinding roller becomes worn, the entire grinding roller needs to be replaced, which leads to high costs.

[0005] Therefore, a new technical solution is needed to address the above problems. Summary of the Invention

[0006] In order to reduce processing costs by eliminating the need to replace the entire grinding roller after it wears out, this application provides a grinding and cleaning device for color steel plate processing.

[0007] This application provides a color steel plate processing, grinding, and cleaning device, which adopts the following technical solution:

[0008] A color steel plate processing, grinding and cleaning device includes a frame, a conveying mechanism mounted on the frame for conveying workpieces, a grinding mechanism for grinding workpieces, and a cleaning mechanism for cleaning workpieces.

[0009] The conveying mechanism includes a plurality of conveying rollers rotatably connected to the frame and a conveying drive component that drives the conveying rollers to rotate. Adjacent conveying rollers are connected by chains and rotate synchronously.

[0010] The grinding mechanism includes several base rollers rotatably connected to the frame, a grinding drive component for driving the base rollers to rotate, several grinding discs detachably connected to the outer wall of the base rollers, and a limiting component for limiting the position of the grinding discs. The outer wall of the base rollers can fit against the surface of the workpiece, the grinding discs cover the outer surface of the base rollers, and the grinding discs can abut against the workpiece.

[0011] By adopting the above technical solution, the color steel plate is fed into the grinding mechanism through the conveying mechanism. The grinding mechanism grinds the surface of the color steel plate. After grinding is completed, it is successfully rinsed by the cleaning mechanism. When the grinding disc is worn, the grinding disc can be disassembled and replaced, so that the base roller can continue to process the color steel plate without replacing the entire base roller, thereby reducing the cost in the color steel plate processing process.

[0012] Optional: The base roller is hollow, and the outer wall of the base roller has several connecting holes communicating with its inner cavity. Each grinding disc is provided with several connecting blocks, and the connecting blocks pass through the connecting holes and are inserted into the base roller.

[0013] The limiting component includes a rotating shaft coaxially rotatably connected inside the base roller, a plurality of limiting rods disposed on the outer wall of the rotating shaft, and fasteners that limit the rotation of the rotating shaft. The limiting rods can be respectively inserted into a connecting block, and the limiting rods can maintain contact with the inner wall of the base roller.

[0014] By adopting the above technical solution, when replacing the grinding disc, the rotating shaft is rotated to disengage the limiting rod from the connecting block. Then, the connecting block of the grinding disc can be removed from the connecting hole, thus disassembling the worn grinding disc. After that, the connecting block of the new grinding disc is inserted into the connecting hole, and the rotating shaft is rotated in the opposite direction to insert the limiting rod into the connecting block, thus fixing the grinding disc. During the disassembly and installation process, only the rotating shaft needs to be rotated to fix the grinding disc, making the disassembly and installation process of the grinding disc more convenient.

[0015] Optionally: the polishing disc has an arc of 180 degrees, adjacent polishing discs are fixedly connected, a snap-fit ​​groove is provided on the end of the polishing disc parallel to its axis, and a snap-fit ​​block is provided on the other end of the polishing disc, the snap-fit ​​block can be embedded in the snap-fit ​​groove of the adjacent polishing disc.

[0016] By adopting the above technical solution, the position of the grinding disc is limited by the interlocking of the locking groove and the locking block, and the connection between the grinding discs. This ensures that the position of the end of the grinding disc remains stable during the grinding process, thereby making the grinding process of the grinding disc stable.

[0017] Optionally: The inner wall of the base roller is fixed with several reinforcing blocks, which are respectively disposed on both sides of the connecting hole, and the limiting rod can pass through two reinforcing blocks at the same time.

[0018] By adopting the above technical solution, the movement of the limiting rod is guided by the reinforcing block, so that the limiting rod can be properly inserted into the connecting block during the movement, thus making the fixing process of the lower limiting rod to the grinding disc less affected.

[0019] Optionally, a number of magnetic components are fixed on the outer wall of the base roller, and the magnetic components can be attracted to the grinding disc.

[0020] By adopting the above technical solution, the grinding disc can still be connected to the outer wall of the base roller after the limiting rod is disengaged from the connecting block, thus making the installation process of the grinding disc more convenient.

[0021] Optionally: An extension disc is fixed to the end face of the rotating shaft, an adjustment groove is passed through the end face of the extension disc, an adjustment block is fixed to the end face of the base roller and embedded in the adjustment groove, the adjustment block can abut against the adjustment groove to limit the rotation range of the extension disc, and the fastener passes through the extension disc and is fixed to the base roller.

[0022] By adopting the above technical solution, the rotation amplitude of the rotating shaft is limited by the cooperation of the extension plate and the adjustment block, so that the limit rod will not move after it is separated from the connecting block. This prevents the limit rod from falling directly off the reinforcing block and also makes the subsequent process of the limit rod being inserted into the connecting block less affected.

[0023] Optionally: The end of the base roller is detachably connected to a driving component that drives the rotating shaft to rotate. The driving component is sleeved on the end face of the base roller and can rotate synchronously. A rotating wheel is rotatably connected to the driving component. Several driving rods are fixed on the rotating wheel. Several driving grooves that cooperate with the driving rods are opened on the end face of the rotating shaft. The driving rods can be inserted into the driving grooves.

[0024] By adopting the above technical solution, the drive wheel is connected to the base roller, and the rotating wheel is connected to the rotating shaft, thereby applying forces in opposite directions to the drive wheel and the rotating shaft to make the rotating shaft rotate. There is a position where force is directly applied during the rotation of the rotating shaft, which makes the rotation process of the rotating shaft more convenient.

[0025] Optionally, the cleaning mechanism includes a water storage tank, a plurality of nozzles mounted on a frame, and a water pump that drives liquid into the nozzles. The nozzles are respectively mounted on the upper and lower sides of the conveying roller, and the outlet of the nozzles faces the workpiece.

[0026] By adopting the above technical solution, after the color steel plate is polished, it passes between two nozzles, and the water jets from the nozzles wash away the debris on the color steel plate.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The grinding disc is detachably connected to the base roller, so that the grinding disc can be replaced directly after it is worn, without having to replace the entire base roller, thereby reducing production costs;

[0029] 2. The position of the base roller is defined by the drive wheel sleeved outside the base roller, and the rotation wheel connected to the rotation shaft applies force to the rotation shaft, thereby realizing the relative rotation of the base roller and the rotation shaft. In the process of the relative rotation of the rotation shaft and the base roller, there is a position where force can be directly applied, making the rotation process of the rotation shaft more labor-saving.

Detailed Implementation

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] This application discloses a color steel plate processing, grinding, and cleaning device, such as... Figure 1 As shown, it includes a frame 1, a conveying mechanism 2 for conveying workpieces mounted on the frame 1, a grinding mechanism 3 for grinding workpieces mounted on the frame 1, and a cleaning mechanism 4 for cleaning workpieces mounted on the frame 1.

[0037] The conveying mechanism 2 includes a plurality of conveying rollers 21 rotatably connected to the frame 1 and a conveying drive component 22 for driving the conveying rollers 21 to rotate. In this embodiment, the conveying drive component 22 is a motor. A reducer is connected to the output shaft of the conveying drive component 22. The output shaft of the reducer is connected to a conveying roller 21 through a gear, thereby driving the conveying roller 21 to rotate. The conveying rollers 21 are arranged in a horizontal direction, and adjacent conveying rollers 21 are connected by chains, so that the conveying rollers 21 can rotate synchronously.

[0038] like Figure 1 and Figure 2 As shown, the grinding mechanism 3 includes two base rollers 31 rotatably connected to the frame 1, a grinding drive component for driving the base rollers 31 to rotate, several grinding discs 32 detachably connected to the outer wall of the base rollers 31, and a limiting component 33 for limiting the position of the grinding discs 32. The base rollers 31 are arranged vertically, allowing the workpiece to pass between the two base rollers 31. In this embodiment, the grinding drive component is a motor, and a reducer is connected to the output shaft of the grinding drive component. The output shaft of the reducer is connected to one base roller 31 via gears, and the two base rollers 31 are connected via gears, thereby enabling the grinding drive component to drive the base rollers 31 to rotate in opposite directions. Figure 3 As shown, the outer surface of the base roller 31 is irregularly shaped and can mate with the irregularities on the color steel plate. The base roller 31 includes two semi-cylindrical splicing parts 311. The sidewalls of the splicing parts 311 that are close to each other are open. The two splicing parts 311 are fixed together by bolts to form a columnar base roller 31. The grinding disc 32 has an arc of 180 degrees. It is spliced ​​together to form a complete ring and is fitted over the base roller 31. The grinding disc 32 can cover the outer wall of the base roller 31, so that the color steel plate can be ground by the grinding disc 32 during the rotation of the base roller 31. After the grinding disc 32 wears out, it can be replaced.

[0039] like Figure 2 and Figure 4As shown, the grinding disc 32 includes a metal sheet 322 and a friction disc 321 disposed outside the metal sheet 322. Several connecting blocks 323 are disposed on the side wall of the metal sheet 322 near the base roller 31. Several connecting holes 312 communicating with the inner cavity of the base roller 31 are opened on the outer wall of the base roller 31. The connecting blocks 323 can pass through the connecting holes 312 and be inserted into the base roller 31. The outer wall of the connecting block 323 is in contact with the inner wall of the connecting hole 312. The limiting member 33 includes a rotating shaft 331 coaxially rotating within the base roller 31, several limiting rods 332 disposed on the outer wall of the rotating shaft 331, and fasteners 333 for limiting the rotation of the rotating shaft 331. Several connecting rods 334 are circumferentially disposed on the outer wall of the rotating shaft 331. The limiting rods 332 are disposed at the ends of the connecting rods 334 away from the rotating shaft 331. The limiting rods 332 are arc-shaped, and their outer walls are in contact with the inner wall of the base roller 31. The limiting rod 332 can be inserted into the connecting block 323 to limit the position of the connecting block 323, so that the connecting block 323 will not fall out of the connecting hole 312, thereby keeping the connection of the grinding disc 32 stable.

[0040] like Figure 4 As shown, in order to make it easier for the limiting rod 332 to pass through the connecting block 323, several reinforcing blocks 34 are also fixed on the inner wall of the base roller 31. The reinforcing blocks 34 are arranged on both sides of the connecting block 323. The limiting rod 332 can pass through two reinforcing blocks 34 at the same time, thereby using the reinforcing blocks 34 to limit the position of the limiting rod 332, making it easier for the limiting rod 332 to pass through the connecting block 323.

[0041] like Figure 2 As shown, to prevent accidents such as warping of the end face of the grinding disc 32 facing its direction of movement during the grinding process, several locking grooves 325 are formed on the end face of the metal disc 322 parallel to its axis. Several locking blocks 324 are fixed on the other end face of the metal disc 322. The locking blocks 324 can be inserted into the locking grooves 325, thereby using the structure of the grinding disc 32 itself to limit the position of the grinding disc 32, so that the grinding disc 32 can remain stable during the grinding process.

[0042] like Figure 2 As shown, in order to ensure that the grinding disc 32 can remain connected to the base roller 31 without falling off after the limiting rod 332 is disengaged from the connecting block 323, several magnetic components 313 are bolted to the outer wall of the base roller 31. The magnetic components 313 can attract the metal sheet 322, thereby limiting the position of the grinding disc 32 and making the installation and removal of the grinding disc 32 more convenient.

[0043] like Figure 2 and Figure 3As shown, an extension disc 35 is coaxially fixed to the end of the rotating shaft 331 away from the grinding drive component. An adjustment groove 351 passes through the end face of the extension disc 35. An adjustment block 36 is bolted to the end face of the base roller 31 near the extension disc 35. The adjustment block 36 is embedded in the adjustment groove 351. After the limiting rod 332 is disengaged from the connecting block 323, the adjustment groove 351 can abut against the adjustment block 36, thereby limiting the rotation amplitude of the rotating shaft 331, preventing the limiting rod 332 from detaching from the reinforcing block 34, and making the subsequent insertion of the limiting rod 332 into the connecting block 323 less affected. In this embodiment, the fastener 333 is a bolt. The fastener 333 passes through the extension disc 35. After the limiting rod 332 passes through the connecting block 323 and the two reinforcing blocks 34, the fastener 333 can pass through the base roller 31 and be threadedly fixed to the base roller 31.

[0044] like Figure 3 As shown, to facilitate the rotation of the rotating shaft 331, a drive wheel 5 for rotating the rotating shaft 331 can be detachably connected to the end of the base roller 31 away from the grinding drive wheel 5. The drive wheel 5 is sleeved on the end face of the base roller 31, and the connection position between the drive wheel 5 and the base roller 31 is octagonal, thereby enabling the drive wheel 5 to drive the base roller 31 to rotate. A rotating hole is coaxially passed through the end face of the drive wheel 5, and a rotating wheel 52 is coaxially rotatably connected in the rotating hole. The rotating wheel 52 is annular, and a handle 55 is provided on its end face away from the base roller 31. An extension plate 53 is fixed inside the rotating wheel 52, and several drive rods 54 are fixed on the end face of the extension plate 53 near the base roller 31. Several drive grooves 352 are opened on the end face of the rotating shaft 331 away from the grinding drive component 37, and the drive rods 54 can be inserted into the drive grooves 352. Forces are applied in opposite directions to the drive wheel 5 and the rotating wheel 52, thereby causing the rotating shaft 331 to rotate relative to the base roller 31, thus separating the limit rod 332 from the connecting block 323. During the rotation of the rotating shaft 331 relative to the base roller 31, there is a position where force can be directly applied, making the rotation of the rotating shaft 331 more convenient.

[0045] like Figure 1 As shown, the cleaning mechanism 4 includes a water storage tank 41, a plurality of nozzles 42 mounted on the frame 1, and a water pump 43 that drives liquid into the nozzles 42. The inlet of the water pump 43 is connected to the water storage tank 41, and the outlet of the water pump 43 is simultaneously connected to the inlet of the plurality of nozzles 42. The nozzles 42 are respectively positioned above and below the conveyor roller 21, and the outlets of the nozzles 42 all face the workpiece, thereby using the water jets from the nozzles 42 to clean the debris generated on the surface of the workpiece due to grinding.

[0046] The implementation principle of this embodiment is as follows: the color steel plate passes between two base rollers 31, and the surface of the color steel plate is polished by the grinding disc 32, followed by rinsing with liquid. When the grinding disc 32 needs to be replaced, first loosen the fastener 333 to disengage it from the base roller 31, put the drive wheel 5 on the base roller 31 and insert the drive rod 54 into the drive groove on the rotating shaft 331, apply opposite forces to the drive wheel 5 and the rotating wheel 52 to make the rotating shaft 331 rotate until it abuts against the adjusting block 36. Manually remove the grinding disc 32 that needs to be replaced, install the new grinding disc 32 on the base roller 31 and insert the connecting block 323 into the connecting hole 312, apply opposite forces to the drive wheel 5 and the rotating wheel 52 to make the rotating shaft 331 rotate until it can no longer rotate, remove the drive wheel 5 and tighten the fastener 333.

[0047] The embodiments described in this specific implementation are 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.
