Description

Technical Field

[0001] The invention relates to the field of surface cleaning, in particular to a surface cleaning device for coating. Background Art

[0002] Before painting the workpiece, in order to improve the adhesion of the paint, the outer surface of the workpiece needs to be processed. Among them, improving the flatness of the substrate surface is very important for the casting surface. The cleaning device must be used to thoroughly remove the molding sand, welding slag and rust, otherwise it will affect the appearance of the coating.

[0003] However, most of the existing surface cleaning devices use angle grinders, etc. Since some workpieces have relatively narrow gaps, their grinding discs cannot extend into the gaps, and thus cannot effectively clean the gaps with smaller widths. In addition, their grinding discs have a certain curvature, which makes it inconvenient for the device to grind relatively flat surfaces. In addition, their grinding discs are inconvenient to disassemble and assemble. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a surface cleaning device for coating.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a surface cleaning device for coating, comprising a support plate, an outer shell and a cover plate, the support plate and the cover plate are respectively arranged at two ends of the outer shell, and the support plate is fixedly connected to the bottom of the outer shell, a second rotating shaft and a third rotating shaft are rotatably plugged on the plate wall of the support plate close to the cover plate, the second rotating shaft and the third rotating shaft are respectively arranged at two ends of the support plate, and a first transmission roller and a second transmission roller are respectively fixedly sleeved on the shaft walls of the second rotating shaft and the third rotating shaft; A fourth rotating shaft is rotatably plugged on the plate wall of the support plate away from the cover plate, a toggle block is fixedly connected to the fourth rotating shaft, the toggle block is movably connected to the support plate, both ends of the toggle block are rotatably plugged with a fifth rotating shaft, two arc-shaped through grooves are provided on the plate wall of the support plate corresponding to the two fifth rotating shafts, one end of the fifth rotating shaft away from the toggle block movably passes through adjacent arc-shaped through grooves and is fixedly connected to a support roller, and a grinding belt is commonly transmission-connected on the roller walls of the two support rollers and the first transmission roller and the second transmission roller; A travel groove is provided on one side of the outer shell body close to the cover plate, a travel plate is slidably inserted into the interior of the travel groove, one end of the travel plate inserted into the interior of the travel groove is fixedly connected to a tension spring, the other end of the tension spring is connected to the inner wall of the travel groove, one end of the travel plate extending out of the travel groove is hinged to the cover plate, and corresponding through holes are provided on the plate wall of the cover plate corresponding to the first rotating shaft, the second rotating shaft, the third rotating shaft and the two fifth rotating shafts, and the ends of the first rotating shaft, the second rotating shaft, the third rotating shaft and the two fifth rotating shafts are movably inserted into adjacent through holes.

[0006] Specifically, a motor is installed on the outer plate wall of the support plate away from the cover plate. The output end of the motor is fixedly connected to the first rotating shaft through a coupling. The other end of the first rotating shaft moves through the support plate and is fixedly sleeved with a transmission wheel. The transmission wheel is connected to the second transmission roller through a transmission belt.

One end of the travel plate 23 inserted into the travel groove 22 is fixedly connected with a tension spring 24, and the other end of the tension spring 24 is connected to the inner wall of the travel groove 22. One end of the travel plate 23 extending out of the travel groove 22 is hinged to the cover plate 25, and corresponding through holes 26 are provided on the plate wall of the cover plate 25 corresponding to the first rotating shaft 5, the second rotating shaft 7, the third rotating shaft 9 and the two fifth rotating shafts 16, and the ends of the first rotating shaft 5, the second rotating shaft 7, the third rotating shaft 9 and the two fifth rotating shafts 16 are movably inserted into adjacent through holes 26.

[0017] A motor 4 is installed on the outer plate wall of the support plate 1 away from the cover plate 25. The output end of the motor 4 is fixedly connected to the first rotating shaft 5 through a coupling. The other end of the first rotating shaft 5 can move through the support plate 1 and is fixedly sleeved with a transmission wheel 6. The transmission wheel 6 is connected to the second transmission roller 10 through a transmission belt 11. The motor 4 can drive the second transmission roller 10 to rotate through the transmission wheel 6 and the transmission belt 11, thereby starting the driving device.

[0018] A holding frame 3 is fixedly connected to one side of the outer shell 2. The setting of the holding frame 3 can make the device more convenient when holding.

[0019] A mounting frame 19 is inserted into the outer wall of the outer shell 2 close to the holding frame 3, and a brush plate 20 is inserted into the top of the other end of the mounting frame 19. The brush plate 20 passes through one end of the mounting frame 19 and contacts the grinding belt 27. The mounting frame 19 can prevent the debris generated during the grinding process from splashing onto the user's arm, and the brush plate 20 can scrape off the debris remaining on the grinding belt 27.

[0020] A limiting ball block 14 is fixedly connected to the plate wall of the toggle block 12 close to the support plate 1, and a plurality of matching limiting ball grooves 15 are provided on the plate wall of the support plate 1 at equal intervals corresponding to the limiting ball block 14, and the limiting ball block 14 is matched with the limiting ball grooves 15, and the limiting ball grooves 15 matched with the limiting ball block 14 and arranged at equal intervals can limit and lock the toggle block 12.

[0021] A battery 21 is embedded in the inner top of the outer shell 2 . The battery 21 is electrically connected to the motor 4 . The battery 21 can provide electrical energy for the motor 4 .

[0022] When in use, the grip frame 3 is held by hand, and the motor 4 is started by the PLC controller. The output end of the motor 4 drives the first rotating shaft 5 to rotate. When the first rotating shaft 5 rotates, it can drive the second transmission roller 10 to rotate through the transmission wheel 6 and the transmission belt 11. When the second transmission roller 10 rotates, it can drive the grinding belt 27 to rotate along the transmission roller and the support roller 18, so that the grinding belt 27 can grind the workpiece. During the grinding process, since the diameter of the first transmission roller 8 is small, the grinding belt 27 can extend to a gap with a smaller width for grinding, and its transmission roller and support roller 18 can make part of the grinding belt 27 extend into a planar structure, so that the device can effectively grind the surface of the workpiece to be flat; When the grinding belt 27 is disassembled and assembled, the cover plate 25 is pulled in the direction away from the support plate 1. When the cover plate 25 is pulled, it can drive the hinged stroke plate 23 to extend outward along the stroke groove 22, and the tension spring 24 is extended under the force. When the cover plate 25 is separated from the rotating shaft, the cover plate 25 can be flipped upward. At this time, the cover plate 25 and the stroke plate 23 will contact with the outer shell 2 under the tension of the tension spring 24 and be temporarily limited. After the cover plate 25 is flipped, the toggle block 12 is rotated again. When the toggle block 12 rotates with the fourth rotating shaft 13 as the axis, it can drive the limiting ball block 14 to be clamped into the adjacent limiting ball groove 15, and the toggle block 12 can also drive the fifth rotating shaft 16 to rotate along the arc-shaped through groove 17 when rotating. When the fifth rotating shaft 16 rotates, it can drive the support roller 18 to separate from the grinding belt 27, as shown in the attached figure. Figure 4 As shown, at this time, the grinding belt 27 loses the support of the support roller 18 and is in a loose state. The grinding belt 27 can be easily disassembled and replaced. After the replacement is completed, the toggle block 12 is rotated to reset the support roller 18. Finally, the cover plate 25 is pulled away from the outer shell 2. After the cover plate 25 is pulled until it can be flipped downward and reset, the pull on the cover plate 25 can be released. The cover plate 25 will stably support and limit the rotating shaft through the through hole 26.
