Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] In the embodiment, it is given by Figure 1 A workpiece sandblasting and coating mechanism, optionally but not limited to including: a sandblasting box 1;

[0032] The workpiece placement mechanism 2 is provided on the sandblasting box 1 and is used to carry the workpiece;

[0033] The recovery mechanism 3 is provided on the sandblasting box 1 and includes a scraping member 33 and a recovery box 35. The scraping member 33 is slidably provided on the inner wall of the sandblasting box 1, and the recovery box 35 is provided on the inner bottom wall of the sandblasting box 1. The sand material sprayed on the inner wall of the sandblasting box 1 is scraped off by the scraping member 33 and falls into the recovery box 35 for recovery;

[0034] The cooling mechanism 4 is provided on the sandblasting box 1 and is used to cool and form the sand material sprayed on the surface of the workpiece.

[0035] In this embodiment, a workpiece sandblasting and coating mechanism of the present utility model is given. By placing the workpiece on the workpiece placement mechanism 2, after sandblasting the outer surface of the workpiece through the sandblasting box 1, the scraping member 33 on the recovery mechanism 3 scrapes the sand material inside the sandblasting box 1, so that the sandblasting adhered to the inside of the sandblasting box 1 falls into the recovery box 35 for recycling, thereby reducing the cost of workpiece sandblasting. Then, the sandblasting on the surface of the workpiece is cooled by the cooling mechanism 4, so that the sandblasting can firmly adhere to the surface of the workpiece, thus improving the sandblasting effect of the workpiece.

[0036] I. Sandblasting box 1

[0037] Preferably, as Figure 1 shown, the sandblasting box 1 may also optionally but not limited to be provided with two box doors 11 and two sandblasting members 12;

[0038] The two box doors 11 are symmetrically arranged left and right and rotatably provided on the sandblasting box 1;

[0039] The two sandblasting members 12 are symmetrically arranged left and right along the workpiece placement mechanism 2 inside the sandblasting box 1 and are used to sandblast the surface of the workpiece.

[0040] In this embodiment, a preferred embodiment of the sandblasting box 1 is given. By fitting the two box doors 11 to the sandblasting box 1, it is avoided that the sand material sprays out of the sandblasting box 1 when sandblasting the workpiece, and then the surface of the workpiece is sandblasted by the two sandblasting members 12.

[0041] II. Workpiece placement mechanism 2

[0042] Preferably, as Figure 1-2 shown, the workpiece placement mechanism 2 may optionally but not limited to include: a servo motor 21 provided on the sandblasting box 1; a mounting plate 22 provided at the output end of the servo motor 21 and the mounting plate 22 is located inside the sandblasting box 1; four connecting rods 23 rotatably provided inside the mounting plate 22; a placing member 24 provided outside the connecting rods 23;

[0043] The connecting ring 25 is arranged between the lower end faces of the four connecting rods 23, and the four connecting rods 23 can rotate on the connecting ring 25; the four driven gears 26 are rotatably arranged on the upper end face of the mounting plate 22, and the driven gears 26 are respectively connected to the connecting rods 23 for driving the connecting rods 23 to rotate;

[0044] The driving gear 27 is rotatably arranged on the mounting plate 22 and meshes with the driven gear 26 for driving the driven gear 26 to rotate; the mounting frame 28 is arranged on the mounting plate 22; the AC motor 29 is arranged on the mounting frame 28 for driving the driven gear 26 to rotate.

[0045] More preferably, a plurality of placing members 24 are arranged on each of the four connecting rods 23, and the plurality of placing members 24 are evenly distributed on the outer side of the connecting rods 23.

[0046] More preferably, the placing member 24 may include, but is not limited to: a placing plate 241 arranged on the outer side of the connecting rod 23; a plurality of hooks 242 arranged at equal intervals on the lower end face of the placing plate 241.

[0047] In this embodiment, a preferred embodiment of the sandblasting box 1 is given. The workpiece to be sandblasted is placed on the hook 242. The servo motor 21 drives the mounting plate 22 to rotate, so that the mounting plate 22 drives the placing member 24 on the connecting rod 23 to rotate. The AC motor 29 drives the driven gear 26 on the connecting rod 23 to rotate. The driven gear 26 meshes with the driving gear 27, so that when the driven gear 26 drives the driving gear 27 to rotate, the driving gear 27 will drive the other three driven gears 26 to rotate. Thus, when the mounting plate 22 drives the four connecting rods 23 to rotate as a whole, the connecting rods 23 can also rotate on the mounting plate 22, so that the orientation of the workpiece can be continuously adjusted, making the sandblasting effect on the workpiece surface better.

[0048] III. Recycling mechanism 3

[0049] Preferably, as Figure 3-4 shown, the recycling mechanism 3 may include, but is not limited to: two electric push rods 31 symmetrically arranged on both sides of the sandblasting box 1; a connecting frame 32, and the connecting frame 32 is arranged at the output end of the electric push rod 31; a collecting hopper 34 arranged inside the sandblasting box 1.

[0050] More preferably, as Figure 3 shown, a scraping member 33 is arranged between the lower end faces of the two connecting frames 32, and the outer side of the scraping member 33 is in close contact with the inner side of the sandblasting box 1.

[0051] More preferably, as Figure 1 and Figure 4As shown, a placement groove is provided on the sandblasting box 1, and the recycling box 35 is arranged in the placement groove; the collecting hopper 34 is communicated with the placement groove, and a sieve mesh 341 is arranged inside the collecting hopper 34.

[0052] In this embodiment, a preferred embodiment of the sandblasting box 1 is given. The connecting frame 32 is driven to move by two electric push rods 31. The connecting frame 32 drives the scraping member 33 to move downward, so that the scraping member 33 scrapes the sand adhered to the inner side of the sandblasting box 1. The scraped sand falls into the collecting hopper 34. The collecting hopper 34 facilitates the scraped sand to fall into the recycling box 35. And the sieve mesh 341 arranged inside the collecting hopper 34 can filter the sand, avoiding the mixing of impurities and sand. In this way, the sand adhered to the inner side of the sandblasting box 1 can be scraped and recycled, thereby reducing the sandblasting cost on the surface of the workpiece.

[0056] In this embodiment, a preferred embodiment of the sandblasting box 1 is given. The coolant in the liquid storage tank 41 is cooled by the semiconductor refrigeration sheet 42, and the water pump 43 sends the coolant into the heat exchange tube 44. The heat exchange tube 44 exchanges heat in the sandblasting box 1, so that the temperature inside the sandblasting box 1 is reduced, and the sand on the surface of the workpiece is quickly cooled and formed.
