Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A metal sheet surface spraying machine includes a worktable 1, a spraying box 3, a controller 4, and a spraying mechanism 5 arranged above the worktable 1, and a moving mechanism 2 arranged above the worktable 1 for moving the metal sheet out of the spraying area. The moving mechanism 2 includes:

[0027] The sliding unit 21 is disposed above the workbench 1 and includes a fixed frame 211 fixedly installed on the top of the workbench 1, an internal clamping plate 2113 of the fixed frame 211, a sliding frame 2110 slidably installed on the surface of the clamping plate 2113, a rotating frame 2111 rotatably installed inside the sliding frame 2110, and a T-shaped groove 2112 is opened in the side plate of the rotating frame 2111. The rotating frame 2111 slides inside the T-shaped groove 2112 by a T-shaped block on one side of the clamping plate 2113, thereby clamping the metal plate. The metal plate is removed from the spraying area by the sliding frame 2110 sliding on the surface of the clamping plate 2113.

[0028] The flipping unit 22 is disposed on one side of the sliding frame 2110 and is used to flip the metal plate.

[0029] In this embodiment, rectangular grooves 212 and limiting grooves 213 are provided on both the front and rear sides of the fixing frame 211. A secondary pulley 214 and a main pulley 215 are rotatably installed inside the rectangular groove 212. A synchronous belt 216 is fitted on the surface of the secondary pulley 214 and the main pulley 215. A connecting block 217 is fixedly installed on the inner side of the synchronous belt 216. A fixing block 218 is fixedly installed at the bottom end of the connecting block 217. One end of the fixing block 218 is fixedly connected to the sliding frame 2110. The fixing block 218 is located inside the limiting groove 213 and is adapted to slide.

[0030] The rectangular groove 212 and limiting groove 213 on the fixed frame 211, in conjunction with the synchronous belt 216 and connecting block 217, ensure that the sliding frame 2110 slides stably along a predetermined trajectory during movement. The synchronous belt transmission reduces mechanical vibration, improving the accuracy and reliability of the metal plate moving out of / into the spraying area. At the same time, the limiting groove 213 guides the sliding of the fixed block 218, preventing deviation and improving the safety of automated operation.

[0031] In this embodiment, a dual-axis motor 219 is fixedly installed at the right end of the fixing frame 211, and the output shafts at both ends of the dual-axis motor 219 pass through the fixing frame 211 and are fixedly connected to the main pulley 215 for driving the main pulley 215.

[0032] The dual-axis motor 219, model CTD41A, is electrically connected to an external power supply and operated via a user-controlled control panel. The motor directly drives the main pulley 215, achieving bidirectional power transmission through the synchronous belt 216, simplifying the transmission structure and improving drive efficiency. The dual-axis design ensures synchronous movement on both sides, avoiding jamming caused by uneven force on one side. Furthermore, motor control replaces manual operation, significantly reducing the risk of workers being exposed to harmful spraying environments.

[0033] In this embodiment, the flipping unit 22 includes a mounting bracket 221 fixedly installed on the left side of the sliding frame 2110. A cylinder 222 is fixedly installed on the left side of the mounting bracket 221, and a drive column 223 is fixedly installed through the mounting bracket 221 at the output end of the cylinder 222. The drive column 223 is fixedly connected to the left side of the clamping plate 2113.

[0034] The cylinder 222 is model DSNU-20-50-PPV-A. It is electrically connected to an external power source and can be opened and closed by a human-operated control panel. When a metal plate is placed between the rotating frame 2111 and the clamping plate 2113, the cylinder 222 moves to move the clamping plate 2113 to clamp the metal plate.

[0035] In this embodiment, a rotating sleeve 224 is rotatably installed inside the left plate of the sliding frame 2110. A movable slot 226 is provided inside the rotating sleeve 224, and the drive column 223 is limited to move inside the movable slot 226 by means of a protrusion. A positioning groove 225 is provided on the surface of the rotating sleeve 224, and a rotating wheel 227 is fixedly installed on the surface of the rotating sleeve 224 for flipping the rotating frame 2111 and the clamping plate 2113 to achieve the flipping of the metal plate. A sliding rod 228 is slidably installed inside the left plate of the mounting frame 221. A limiting block 229 is fixedly installed at one end of the sliding rod 228, and the limiting block 229 has a protruding end that slides inside the positioning groove 225. A return spring 2210 is fitted on the surface of the sliding rod 228, and the position of the rotating sleeve 224 is fixed by means of the protruding end of the limiting block 229 sliding inside the positioning groove 225.

[0036] The user pulls the sliding rod 228, causing the limiting block 229 to press the return spring 2210. The protruding end of the limiting block 229 moves from the straight groove of the positioning groove 225 to the arc groove of the positioning groove 225. The user rotates the rotating sleeve 224 through the rotating wheel 227. The rotating sleeve 224 drives the clamping plate 2113 and the sliding frame 2110 to rotate through the drive column 223. At the same time, the protruding end of the limiting block 229 slides inside the arc groove of the positioning groove 225. After the rotating sleeve 224 rotates 180 degrees, the return spring 2210 pushes the limiting block 229 with its own elasticity, causing the protruding end of the limiting block 229 to slide into the straight groove on the other side of the positioning groove 225, thereby realizing the flipping of the metal plate and enabling double-sided spraying without disassembling the metal plate.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, firstly, the metal plate is placed between the rotating frame 2111 and the clamping plate 2113. The cylinder 222 runs to push the clamping plate 2113 to move and clamp the metal plate.

[0039] Secondly, the dual-axis motor 219 drives the main pulley 215 to rotate, and the main pulley 215 drives the synchronous belt 216 to rotate through the secondary pulley 214. The synchronous belt 216 drives the connecting block 217 and the fixed block 218 to move horizontally and linearly. The fixed block 218 drives the sliding frame 2110 to move synchronously and linearly, so that the metal plate enters the interior of the spray box 3. The metal plate is sprayed by the three-axis moving device and the painting device of the spraying mechanism 5.

[0040] Next, the dual-axis motor 219 moves in the opposite direction, causing the metal plate to be moved out of the spray box 3. The operator pulls the sliding rod 228, causing the limiting block 229 to press the return spring 2210. The protruding end of the limiting block 229 moves from the straight groove of the positioning groove 225 to the arc groove of the positioning groove 225. The operator rotates the rotating sleeve 224 through the rotating wheel 227. The rotating sleeve 224 drives the clamping plate 2113 and the sliding frame 2110 to rotate through the drive column 223. At the same time, the protruding end of the limiting block 229 slides inside the arc groove of the positioning groove 225. After the rotating sleeve 224 rotates 180 degrees, the return spring 2210 pushes the limiting block 229 with its own elasticity, causing the protruding end of the limiting block 229 to slide into the straight groove on the other side of the positioning groove 225, thus flipping the metal plate.

[0041] Then the dual-axis motor 219 runs again to move the metal plate into the spray box 3 and spray the reverse side of the metal plate.
