[0025] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] See also Figure 1-4A metal surface treatment pre-cleaning device includes a conveying mechanism 1, which includes a cleaning box 101. The cleaning box 101 has rotating rings 102 on both sides thereof. The lower sides of the two sets of rotating rings 102 are fixedly connected with fixed roller conveyors 103. The fixed roller conveyors 103 are used to provide support and conveyance for the metal workpiece to be cleaned. A moving roller conveyor 104 is arranged above the fixed roller conveyor 103. The two sets of rotating rings 102 are both fixedly penetrated with first hydraulic rods 105. The output ends of the two sets of first hydraulic rods 105 are fixedly connected to the moving roller conveyor 104. The first hydraulic rod 105 can drive the moving roller conveyor 104 to move up and down when starting the work, so that the moving roller conveyor 104 can press and limit the metal workpiece. When the rotating ring 102 rotates, the moving roller conveyor 104 and the metal workpiece can be turned over accordingly.

[0027] A limit plate 106 is provided on one side of the fixed roller conveyor 103. The limit plate 106 is fixedly connected to both sets of rotating rings 102. The setting of the limit plate 106 can limit the metal workpiece during the flipping process to reduce the probability of the metal workpiece falling during the flipping. A plurality of balls 107 are evenly and movably connected to the side of the limit plate 106 close to the fixed roller conveyor 103. The setting of the balls 107 can separate the metal workpiece from the limit plate 106 to reduce the probability of wear between the metal workpiece and the limit plate 106 during the conveying process. The driving mechanism 2 includes a gear ring 205 fixedly connected to the outer side of a rotating ring 102 on one side, a support plate 201 is fixedly connected to one side of the cleaning box 101, and reinforcing rib plates 202 are symmetrically fixedly connected to the top of the support plate 201. Both sets of reinforcing rib plates 202 are fixedly connected to the outer wall of the cleaning box 101. The setting of the reinforcing rib plates 202 can further connect and fix the support plate 201 and the cleaning box 101, thereby improving the connection stability between the support plate 201 and the cleaning box 101.

[0028] The output end of the support plate 201 is fixedly connected with a stepper motor 203, and the output end of the stepper motor 203 is fixedly connected with a gear 204, and the gear 204 is meshed with the gear ring 205. When the stepper motor 203 starts working, it can drive the rotating ring 102 to rotate through the gear 204 and the gear ring 205, thereby driving the fixed roller conveyor 103 and the movable roller conveyor 104 to rotate accordingly, so as to meet the turning of the metal workpiece. The cleaning mechanism 3 includes a sliding plate 301 that is slidably connected to the top of the cleaning box 101, and the bottoms of the two sets of sliding plates 301 are fixedly connected with mounting plates 303, and the opposite sides of the two sets of mounting plates 303 are fixedly connected with U-shaped nozzles 304. The U-shaped nozzle 304 is set for connecting a water pump, so that when the water pump starts working, water can be pumped into the inside of the U-shaped nozzle 304, so as to wash the metal workpiece. The opposite sides of the two sets of rotating rings 102 are rotatably connected with cover plates 112, which are adapted to the rotating rings 102. The cover plates 112 can be closed during the flushing of the metal workpiece to reduce the probability of sewage splashing during the flushing process.

[0029] The interior of the cleaning box 101 is detachably connected with a fixed frame 109, which is located below the rotating ring 102. The interior of the fixed frame 109 is fixedly connected with a filter 110, which can filter the sewage dropped after flushing, thereby filtering and collecting the metal chips in the sewage. Sliding grooves 111 are provided on both sides of the fixed frame 109, and the interiors of the two sets of sliding grooves 111 are provided with guide rails 108 fixedly connected to the cleaning box 101. The guide rails 108 are fixedly connected to the fixed frame 109, and the setting of the guide rails 108 and the sliding grooves 111 can limit the sliding of the fixed frame 109, so as to facilitate the removal of the fixed frame 109 and the filter 110 from the interior of the cleaning box 101. Two sets of second hydraulic rods 302 are fixedly connected to the top of the cleaning box 101, and the output ends of the two sets of second hydraulic rods 302 are respectively fixedly connected to the two sets of sliding plates 301. When starting the work, the sliding plate 301 can be pulled to slide, thereby adjusting the position of the mounting plate 303 and the U-shaped nozzle 304, and then adjusting the flushing position.

[0030] In this embodiment, the fixed roller conveyor 103 and the movable roller conveyor 104 are both prior art and will not be described in detail herein.

[0031] When in use, open one side cover 112, then place the metal workpiece to be cleaned on the top of the fixed roller conveyor 103, then start the fixed roller conveyor 103, convey the metal workpiece to the middle position of the fixed roller conveyor 103, then close the cover 112, and then connect the U-shaped nozzles 304 on both sides to the high-pressure water pump, and the corresponding second hydraulic rod 302 and the high-pressure water pump on the side away from the limiting plate 106, so that the high-pressure water pump can draw water into the corresponding U-shaped nozzle 304 and spray it out. When the second hydraulic rod 302 starts working, it can pull the corresponding sliding plate 301, the mounting plate 303 and the U-shaped nozzle 304 to move to one side of the limiting plate 106, so that the water sprayed from the U-shaped nozzle 304 can rinse the top surface of the metal workpiece on the top of the fixed roller conveyor 103. After the top surface of the metal workpiece is rinsed, start the first hydraulic rod 10 5, so that the first hydraulic rod 105 drives the movable roller conveyor 104 to move downward until it contacts the top surface of the metal workpiece, and then the stepper motor 203 is started, so that the stepper motor 203 can drive the gear 204, the gear ring 205 and the rotating ring 102 to rotate when rotating, and the rotating ring 102 can drive the fixed roller conveyor 103 and the movable roller conveyor 104 to rotate when rotating, until the fixed roller conveyor 103 and the movable roller conveyor 104 are turned over half a circle, thereby driving the metal workpiece to turn over half a circle, and then the first hydraulic rod 105 is started again, thereby driving the movable roller conveyor 104 and the metal workpiece to move downward, until the metal workpiece is adjusted to a height lower than the U-shaped nozzle 304, and then the high-pressure water pump and the second hydraulic rod 302 on the other side are started, so as to rinse the top surface of the metal workpiece after turning over, thereby improving the cleaning effect of the metal workpiece.
