[0018] When the processing system is used, the cylinder door 107 on the processing cylinder 101 is opened, then the worker hangs the sheet metal part to be processed on the first hook 106 through the threaded hole, then pulls down the sheet metal part, so that the sheet metal part is hung on the second hook 302 through another threaded hole, the cylinder door 107 is closed, at this time, the first hook 106 drives the sliding rod 104 to slide downward, the spring 105 is stretched under the force, and through the cooperation of the first hook 106 and the second hook 302, the sheet metal part is suspended in the middle of the processing cylinder 101, which replaces the conventional clamp type clamping mode and avoids the shielding of the processed part of the sheet metal part, so that the processed part of the sheet metal part is completely exposed, and manual turning is not required.

[0019] When the sheet metal part is processed, the surface of the sheet metal part is sandblasted by the spraying mechanism, so that the surface of the sheet metal part is polished, surface stains are removed, and the surface attachment capacity of the sheet metal part is improved. In the process of sandblasting the sheet metal part, the rotating turret 103 is controlled to rotate in the treatment cylinder 101, thereby driving the first hook 106 to rotate, and the first hook 106 cooperates with the second hook 302 to drive the sheet metal part to rotate, thereby realizing the effect of fully sandblasting the sheet metal part.

[0020] After sandblasting, the spraying mechanism is used to spray pickling solution on the surface of the sheet metal part to remove burrs and debris on the surface of the sheet metal part, and the sand attached to the surface of the sheet metal part can be washed away. After the pickling solution and the sand are mixed, impurities in the sand can be removed to achieve the purpose of sand washing, which facilitates the recycling of the sand.

[0021] Referring to Figures 3-4 , a schematic view of an embodiment according to the present application capable of separating the pickling solution and the sand is shown, further,

[0022] A plurality of leakage grooves 303 are formed in the upper end of the sieve cylinder 301.

[0023] The pickling solution and the sand fall above the sieve cylinder 301, the pickling solution can enter the inside of the sieve cylinder 301 through the plurality of leakage grooves 303, and the sand is isolated above the sieve cylinder 301, thereby realizing the function of separating the pickling solution and the sand, and facilitating the recycling of the sand.

[0024] Referring to Figure 4 , a schematic view of an embodiment according to the present application capable of collecting the pickling solution is shown, further,

[0025] The lower end of the sieve cylinder 301 is provided with a liquid discharge hole 306, after the pickling solution enters the sieve cylinder 301, it can be gathered in the middle along the inner wall of the sieve cylinder 301, and finally discharged through the liquid discharge hole 306, realizing the effect of collecting the pickling solution.

[0026] Referring to Figures 9-10 , a schematic view of an embodiment according to the present application capable of sandblasting and pickling the sheet metal part is shown, further,

[0027] The treatment cylinder 101 is provided with a limiting groove 102, the spraying mechanism comprises a lifting plate 204, and the lifting plate 204 is fixedly connected with a spray gun 205 through bolts.

[0028] When the sheet metal part is sandblasted, the operator connects the spray gun 205 with the sandblasting machine, so that the sand is sprayed out through the spray gun 205, and the spray gun 205 is controlled to move up and down during the rotation of the sheet metal part to fully sandblast the sheet metal part.

[0029] When the sheet metal part is pickled, the worker connects the spray gun 205 with the container containing the pickling liquid, and then uses the pump to spray the pickling liquid on the sheet metal part through the spray gun 205, and controls the spray gun 205 to move up and down during the rotation of the sheet metal part to comprehensively pickle the sheet metal part, and remove the sand adhered on the sheet metal part.

[0030] Referring to Figure 9 , a schematic view of the embodiment for moving the spray gun 205 up or down according to the present application is shown, further,

[0031] The screw rod 203 is rotatably connected to the processing cylinder 101 through a bearing, and the lifting plate 204 is threadedly connected to the screw rod 203.

[0032] By controlling the screw rod 203 to intermittently reciprocate, the lifting plate 204 can be driven to reciprocate up and down, and the function of moving the spray gun 205 up or down is realized.

[0033] Referring to Figures 8-10 , a schematic view of the embodiment for synchronously controlling the screw rod 203 and the rotating frame 103 according to the present application is shown, further,

[0034] The driving motor 201 is fixedly connected to the upper end of the processing cylinder 101 through bolts, the rotating frame 103 is fixedly connected to the output shaft of the driving motor 201 through a coupling, the pulley 202 is fixedly connected to the upper end of the screw rod 203 and the rotating frame 103 through a key, and the two pulleys 202 are connected through a synchronous belt.

[0035] The rotating frame 103 is driven to rotate by the driving motor 201, and the screw rod 203 is synchronously driven to rotate under the cooperation of the two pulleys 202 and the synchronous belt, so that the spray gun 205 can be moved while the sheet metal part is rotating, thereby realizing the effect of comprehensively sandblasting or pickling the sheet metal part, and avoiding that the spray gun stays at a certain position of the sheet metal part for too long time, resulting in uneven sandblasting or pickling effect.

When the arc-shaped plate 206 is separated from the screen cylinder 301, the metal sheet is automatically reset under the pulling force of the spring 105. Under the continuous rotation of the arc-shaped plate 206, the effect of making the metal sheet vibrate up and down during the sandblasting process is realized, so as to promote the falling of the sand and avoid the accumulation of the sand in the metal sheet.
