[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] like Figure 1 As shown, the floating storage device for steel plates before pickling includes a storage component 1, a leveling component 2, and a pickling tank 3. One end of the storage component 1 is connected to the pre-processing device of the steel plate 4, and the other end of the storage component 1 is sequentially connected to the leveling component 2 and the pickling tank 3 along the conveying direction of the steel plate 4. The storage component 1 is used to temporarily store the steel plate 4, the leveling component 2 is used to level and transport the steel plate 4, and the pickling tank 3 is used to pickle the steel plate 4. The lower end of the steel plate 4 is rotatably connected to the storage component 1, the leveling component 2, and the pickling tank 3. With the storage component 1, the pickling process of the steel plate 4 is relatively slow. In order to avoid stopping the entire process during the pickling process of the previous batch of steel plates 4, the steel plates 4 of the pre-processing device can be temporarily stored in the storage component to solve the problem of speed mismatch between processes, save time, reduce costs, and improve work efficiency.
[0031] like Figure 1As shown, the storage component 1 includes two sets of transition platforms 11, a base plate 12, and first rollers 121. The two sets of transition platforms 11 are arranged axially symmetrically. One set of transition platforms 11 is connected to the pre-processing device of the steel plate 4, and the other set of transition platforms 11 is connected to the leveling component 2. The base plate 12 is arranged axially between the two sets of transition platforms 11. The two ends of the multiple sets of first rollers 121 are rotatably connected to the base plate 12, and the lower end of the steel plate 4 is rotatably connected to the periphery of the first rollers 121. The base plate 12 is provided to abut against the lower end surface of the steel plate 4 when it falls, preventing the surface of the steel plate 4 from being scratched and reducing the defect rate.
[0032] like Figure 2 As shown, the transition platform 11 includes a support plate 111, a rotating shaft 112, a drive unit 113, two limiting plates 114, two positioning pins 115, a roller frame 116, and a second roller 117. One end of the support plate 111 is connected to the pre-processing device or leveling assembly 2 of the steel plate 4. The roller frame 116 is hinged to the support plate 111 via the rotating shaft 112. Multiple second rollers 117 are sequentially rotatably connected to the roller frame 116 along the traveling direction of the steel plate 4. The drive unit 113 is located inside the support plate 111, and the output end of the drive unit 113 is fixedly connected to the rotating shaft 112. A limiting plate 114 is provided on each side of the lower end of the support plate 111. A positioning pin 115 is provided in each of the two inner sidewalls of the roller frame 116. The periphery of each positioning pin 115 is slidably connected to a corresponding limiting plate 114. The drive unit 113 is a servo motor, which is existing technology. The servo motor model is HG-SR81. When the production line starts running, the controller is turned on, and the controller controls the drive unit 113 to rotate. The drive unit 113 drives the rotating shaft 112 to rotate, and the rotating shaft 112 drives the roller frame 116 to rotate. The position of the roller frame 116 is limited by the sliding of the positioning pin 115 within the limit plate 114. When the roller frames 116 at both ends are closed, the steel plate 4 is transported out from the previous processing device and transported to the subsequent leveling assembly 2 and pickling tank 3 under the action of the second roller 117. When there is a steel plate 6 being pickled in the pickling tank 3, there is no need to stop the entire production line. The controller controls the drive unit 113 to rotate, lowering the roller frames 116 at both ends, and the steel plate 4 will fall naturally under the action of gravity.
[0033] like Figure 3 and Figure 4As shown, the leveling assembly 2 includes a frame 21, a power roller 22, a driven roller 23, a sprocket 24, a chain 25, and a drive motor 26. One end of the frame 21 is connected to the transition platform 11, and the other end of the frame 21 is connected to the pickling tank 3. Multiple power rollers 22 are sequentially rotatably connected to the two side walls of the frame 21 along the traveling direction of the steel plate 4. The outer periphery of the power rollers 22 is rotatably connected to the lower surface of the steel plate 4. Multiple driven rollers 23 are sequentially rotatably connected to the two side walls of the frame 21 along the traveling direction of the steel plate 4. The outer periphery of the driven rollers 23 is rotatably connected to the upper surface of the steel plate 4. The driven rollers 23 and the power rollers 22 are arranged alternately. One end of each power roller 22 is fitted with a sprocket 24. Multiple sprockets 24 are fitted with chains 25 to form a synchronous transmission structure. The drive motor 26 is installed at the bottom of the frame 21, and the movable end of the drive motor 26 is connected to any one of the sprockets 24. The drive motor 26 is existing technology, model MS1H4-40B30CB. When the steel plate 4 passes through, the controller controls the drive motor 26 to rotate, and drives the power roller 22 through the sprocket 24 and chain 25. The power roller 22 and driven roller 23 repeatedly roll over both sides of the steel plate 4 to flatten the steel plate 4 and eliminate internal stress. A leveling component 2 is provided, which can flatten the steel plate 4, eliminate the small deformation of the steel plate 4 in the storage component 1, and also eliminate the internal stress of the steel plate 4, facilitating subsequent pickling operations.
[0034] like Figure 5 As shown, the pickling tank 3 includes a pickling tank body 31 and an overflow pipe 32. One end of the pickling tank body 31 is connected to the leveling component 2. The pickling tank body 31 is provided with an overflow hole. The overflow pipe 32 is installed on the outer wall of the pickling tank body 31. One end of the overflow pipe 32 is connected to the overflow hole, and the other end of the overflow pipe 32 is connected to an acid recovery device. Multiple nozzles 33 are provided inside the pickling tank body 31. The nozzles 33 are used to spray acid to rinse the steel plate 4. Multiple bosses 34 are also provided inside the pickling tank body 31. The bosses 34 are used to form a vortex to impact the steel plate 4. When the steel plate 5 passes through, the nozzles 33 spray acid to rinse the steel plate. The multiple bosses can form a vortex with the acid to impact the steel plate 4 during the movement of the steel plate, thereby accelerating the pickling speed and improving the pickling efficiency.
[0035] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
[0037] The working process of the floating storage device before steel plate pickling:
[0038] When the production line starts running, the controller is turned on. The controller controls the drive unit 113 to rotate. The drive unit 113 drives the rotating shaft 112 to rotate. The rotating shaft 112 drives the roller frame 116 to rotate. The position of the roller frame 116 is limited by the sliding of the positioning pin 115 in the limit plate 114. When the roller frames 116 at both ends are closed, the steel plate 4 is transported out from the pre-processing device and transported to the subsequent leveling component 2 and pickling tank 3 under the action of the second roller 117. When the steel plate 4 passes through, the controller controls the drive motor 26 to rotate, and drives the power roller 22 through the sprocket 24 and chain 25. The power roller 22 and driven roller 23 repeatedly roll the two sides of the steel plate 4 to flatten the steel plate 4 and eliminate internal stress. The steel plate 4 enters the pickling tank, and acid is sprayed out through the nozzle 33 to pickle the steel plate 4. When there is a steel plate 6 being pickled in the pickling tank 3, there is no need to stop the entire production line. The controller controls the drive unit 113 to rotate and lowers the roller frames 116 at both ends. The steel plate 4 will fall naturally under the action of gravity to match the speed between each production process.
