Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically a steel plate decoating device. Background Technology

[0002] In the metal processing and manufacturing industry, cleaning the coatings on the surface of steel plates is a common process. Steel plates may be coated with multiple layers of coating during use, and these coatings need to be removed during steel plate refurbishment, reprocessing, or recycling.

[0003] Existing methods for cleaning steel plate coatings mainly rely on manual operation or simple machinery. Workers soak or spray the steel plate surface with paint remover (such as organic solvents) and manually scrape off the coating with tools such as scrapers and wire brushes. This is labor-intensive and inefficient. In addition, paint remover usually contains volatile organic compounds (VOCs), and long-term exposure to these chemicals may cause health problems for workers. Using fixed roller brushes or sandblasting equipment to remove the coating also requires manual adjustment of the steel plate position or equipment parameters, which is inefficient and has poor adaptability to various steel plate specifications.

[0004] Therefore, there is a need for a steel plate coating removal device that can improve coating removal efficiency, reduce labor intensity, reduce direct contact between operators and harmful substances, and be adaptable to steel plates of different sizes. Utility Model Content

[0005] The purpose of this invention is to provide a steel plate decoating device to solve the problems mentioned in the background art, so as to improve the efficiency of coating removal and reduce the health risks to workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A steel plate decoating device includes a support frame, the support frame including a base, and a cleaning mechanism movably disposed inside the support frame. The cleaning mechanism includes two mounting frames that are movably disposed opposite to each other, allowing the two mounting frames to move towards or away from each other. A cleaning roller, a rubber roller, and a spray pipe are respectively mounted on the mounting frames. The cleaning roller is movably mounted on the mounting frames and driven to rotate by a drive device. The liquid inlet end of the spray pipe is connected to a paint remover storage tank via a hydraulic pump. A first transmission mechanism for moving the steel plate in and out of the support frame is disposed at the bottom of the support frame between the two mounting frames.

[0008] As a further embodiment of this utility model: in order to enable the support frame to adapt to steel plates of different sizes in the vertical direction and to assist the first transmission mechanism in driving the steel plates, the base is fixedly connected to two side plates, the upper end of the side plates is movably connected to a top plate, and the lower surface of the top plate is provided with a second transmission mechanism.

[0009] As a further embodiment of this utility model: in order to facilitate the movement of the steel plate in and out of the support frame, the base is provided with a groove along the longitudinal direction, the first transmission mechanism is rotatably connected to the inside of the groove, and two support side plates are symmetrically fixed on the lower surface of the top plate along the longitudinal direction, and the second transmission mechanism is connected between the two support side plates.

[0010] As a further embodiment of this utility model: In order to facilitate the movement of the mounting frame and enable the rubber roller to clamp the steel plate, a slide rail is provided on the base, and a slider is slidably connected to the slide rail. The slider is fixedly connected to the mounting frame, so that the mounting frame can move along the slide rail.

[0011] As a further embodiment of this utility model: in order to drive the mounting bracket to move relative to the support frame, the side plate and the mounting bracket are movably connected by a driving device.

[0012] As a further embodiment of this utility model: in order to move the steel plate in and out of the support frame, both the first transmission mechanism and the second transmission mechanism are composed of multiple concave rollers.

[0013] As a further embodiment of this utility model: in order to facilitate the clamping of the steel plate by the rubber roller and the cleaning roller to clean the surface of the steel plate, at least two rubber rollers are configured on each mounting frame, and the cleaning roller is located between the two rubber rollers.

[0014] As a further embodiment of this utility model: in order to evenly spray the paint remover onto the surface of the steel plate, the outer wall of the spray pipe is evenly provided with liquid outlet holes facing the steel plate along the length direction.

[0015] As a further embodiment of this utility model: in order to clean the residual coating on the surface of the steel plate, an air jet pipe is installed on the mounting bracket, the air jet pipe is connected to an air pump through a pipe, and the outer wall of the air jet pipe is evenly provided with air holes facing the steel plate along the length direction.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model features a novel structure. A first transmission mechanism and a second transmission mechanism are installed on the top and bottom plates of the support frame, with the top plate movably connected to the upper end of the side plate.

[0028] Please see Figure 1-5In this embodiment of the invention, a steel plate decoating device includes a support frame 1, which includes a base 11. Two side plates 12 are welded to opposite sides of the base 11. Each side plate 12 has a driving device 3 13 at both ends of its top. The upper end of each driving device 3 13 is welded to one end of a top plate 14. The driving device 3 13 is used to adjust the height of the top plate 14 relative to the base 11 to accommodate steel plates of different specifications. Two supporting side plates 141 are symmetrically welded along the longitudinal centerline on the lower surface of the top plate 14. A second transmission mechanism 3 is connected between the two supporting side plates 141, allowing the second transmission mechanism 3 to rotate relative to the supporting side plates 141. The driving device 3 13 adjusts the height of the top plate 14, causing the second transmission mechanism 3 to press the steel plate downwards, assisting in the movement of the steel plate and enhancing its stability.

[0029] The base 11 has a groove 111 along its longitudinal centerline. The first transmission mechanism 4 is rotatably connected inside the groove 111. The first transmission mechanism 4 is driven and rotated by the second drive device 5 to actively move the steel plate in and out of the support frame 1, facilitating subsequent paint removal and cleaning of the steel plate. The first transmission mechanism 4 and the second transmission mechanism 3 are vertically aligned to form an adjustable-gap steel plate conveying channel. In this embodiment, the second transmission mechanism 3 and the first transmission mechanism 4 have the same structure, consisting of a main shaft and rollers rotatably connected to the main shaft. The two ends of the main shaft are respectively connected to the two support side plates 141, so that the steel plate is located in the recess of the roller during movement, reducing the possible shaking of the steel plate during movement and avoiding safety risks. To improve stability, multiple rollers can be horizontally arranged. The base 11 is welded with a slide rail 16 that is perpendicular to the side plate 12 in the length direction. The slide rail 16 is slidably connected to a slider 17. A mounting bracket 21 is welded on the slider 17, so that the mounting bracket 21 can move along the slide rail 16. This allows the distance between the mounting bracket 21 and the steel plate to be adjusted according to the different thicknesses of the steel plate, ensuring that the mounting bracket 21 can fully contact the surface of the steel plate.

[0030] The cleaning mechanism 2 includes two mounting frames 21 that are movably arranged relative to each other. The mounting frames 21 are rotatably connected to the cleaning rollers 22. The cleaning rollers are driven and rotated by the drive device 26 to clean the coating on the steel plate. The mounting frames 21 are fixedly connected to the rubber rollers 23. At least two rubber rollers 23 are configured on each mounting frame to facilitate the clamping of the steel plate by the rubber rollers 23. The cleaning rollers 22 are installed between the rubber rollers 23 to keep the steel plate stable during movement. The mounting frames 21 are movably connected to the side plate 12 through the drive device 15. The drive device 15 is used to adjust the distance between the mounting frames 21 and the side plate 12 so that the distance between the two mounting frames 21 can be adjusted according to the thickness of the steel plate, so that the rubber rollers 23 can clamp the steel plate. In this embodiment, the drive device 1 26 and the drive device 2 5 are set as motors, and the drive device 3 13 and the drive device 4 15 can be set as hydraulic cylinders or pneumatic cylinders, so as to facilitate the adjustment of the height of the top plate 14 and the distance between the cleaning mechanism 2 and the steel plate, respectively, to adapt to steel plates of different sizes.

[0031] The mounting frame 21 is welded with a spray pipe 24, which is connected to a hydraulic pump 114 via a pipe 113. The hydraulic pump 114 is connected to a paint remover storage tank 112 via a pipe 113. The outer wall of the spray pipe 24 has uniformly distributed outlet holes 241 facing the steel plate along its length. The paint remover is sprayed out through the outlet holes 241, which facilitates uniform spraying of the paint remover onto the steel plate surface, making the coating easier to remove and clean. The mounting frame 21 is also welded with an air jet pipe 25, which is connected to an air pump 115 via a pipe 113. The outer wall of the air jet pipe 25 has uniformly distributed air holes 251 facing the steel plate along its length. The air jet pipe 25 sprays gas from the air holes 251, which allows the coating remaining on the steel plate to be blown away from the steel plate surface, further ensuring the coating removal effect.

[0032] This utility model has a novel structure and stable operation. In use, a small portion of the steel plate is first vertically placed between the two mounting brackets 21. The drive device 3 13 is then activated, which moves the top plate and adjusts the height of the second transmission mechanism 3. After fixing the steel plate between the second transmission mechanism 3 and the first transmission mechanism 4, the drive device 3 13 is turned off. The drive device 2 5 is then activated, which drives the first transmission mechanism 4, moving the entire steel plate between the two mounting brackets 21. The hydraulic pump 114 is then activated, transporting the paint remover from the paint remover storage tank 112 to the spray pipe 24. The paint remover is then evenly sprayed onto the steel plate surface through the outlet hole 241. The drive device 2 5 is then turned off. After the initial paint removal spraying, the steel plate is left to stand for a period of time. After the paint remover has fully reacted with the coating on the steel plate surface, drive device 4 15 is activated, driving the two mounting brackets 21 to move towards each other along the slide rail 16 until the rubber roller 23 clamps the steel plate. Then drive device 4 15 is turned off. At the same time, drive device 2 5 and drive device 1 26 are activated, causing the steel plate to move repeatedly in and out between the two mounting brackets. The cleaning roller 22 is driven to rotate to clean the coating on the steel plate surface. The air pump 115 is activated, and the air pump 115 delivers gas to the air jet pipe 25. The gas is then sprayed onto the steel plate surface through the air hole 251 to blow off the residual coating on the steel plate surface. After the coating is cleaned, drive device 4 15 is activated, driving the two mounting brackets 21 to move away from each other along the slide rail 16. The rubber roller 23 releases the steel plate. Drive device 2 5 is activated, driving the first transmission mechanism 4 to move the steel plate out between the two mounting brackets 21.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
