The impurities, miscellaneous colors and oxide layer on the surface are removed, and at the same time, the surface of the medium is roughened, the residual stress of the workpiece is eliminated and the surface hardness of the base material is increased.

[0003] In the prior art, when processing aluminum profiles with a large surface area, a single-layer sandblasting method is used for processing. In the actual operation process, we found that during the material discharging process, a large amount of sand grains will accumulate on the surface of the aluminum profile, and it is necessary to manually clean the sand grains falling on the ground.

[0026] Such as Figure 1An aluminum profile alloy processing sandblasting device shown in the figure includes a sandblasting box 1. Above the sandblasting box 1, a sandblasting pipe 2 is arranged. One end of the sandblasting pipe 2 is closed, and the other end is connected to an air compressor (not shown). The sandblasting pipe 2 is connected with multiple branch pipes 21, and sandblasting nozzles 22 are installed at the ends of the branch pipes 21. The sandblasting nozzles 22 are inserted downward from the top of the sandblasting box 1. An opening groove 101 is provided at the front end of the sandblasting box 1, and a sliding table device 3 for carrying aluminum profiles is slidably fitted in the opening groove 101. A material collecting surface 4 is provided at the bottom of the sandblasting box 1. A discharge pipe 41 is provided at the center position of the bottom of the material collecting surface 4. A shaft rod 42 is rotatably arranged at the axis of the discharge pipe 41. A bearing (not shown) and a shaft seal (not shown) are provided between the shaft rod 42 and the discharge pipe 41. The shaft seal is sealed inside the bearing. A spiral blade (not shown) is installed on the shaft rod 42. A motor (not shown) is installed at one end of the discharge pipe 41, and the motor is connected to the shaft rod 42. A discharge port 43 is provided at the bottom of the discharge pipe 41, at the end far from the motor.

[0027] In the above technical solution, the input of the aluminum profile is realized by the sliding-in of the sliding table device 3. After sandblasting, by the sliding-out of the sliding table device 3, it is convenient to remove the sandblasted aluminum profile.

[0028] The motor drives the shaft rod 42 to rotate, and the spiral blade is used to realize the recycling of sand.

[0029] Refer to Figure 1 As shown in the figure, the sliding table device 3 includes a frame 31 and a servo motor 32. A sealing plate 33 is provided at the front end of the frame 31. When the frame 31 slides inward along the opening groove 101 to the limit position, the sealing plate 33 closes the opening groove 101. An ear plate 34 is provided on the side of the sealing plate 33, and a nut pair 35 is provided at the ear plate 34. The servo motor 32 is installed on the side of the sandblasting box 1, and a lead screw 36 is installed at the output end of the servo motor 32. The lead screw 36 cooperates with the nut pair 35, and a first bearing 37 is provided between the lead screw 36 and the sandblasting box 1. A mesh plate 38 is provided inside the frame 31, and mesh holes are evenly distributed on the surface of the mesh plate 38. The aluminum profile to be sandblasted is supported by the mesh plate 38.

[0030] In the above technical solution, the aluminum profile is supported by the mesh plate 38. The servo motor 32 drives the lead screw 36 to rotate, so that the frame 31 slides into the opening groove 101. After sliding in, the sealing plate 33 closes the opening groove 101. The high-speed sand grains generated by sandblasting impact the surface of the aluminum profile. After sandblasting, the frame 31 withdraws, the aluminum profile is turned over and then sent in for sandblasting again. If only one-sided sandblasting is required, the aluminum profile is taken out and the next workpiece is placed.

[0031] Refer toFigure 2 As shown, a plurality of support columns 333 are evenly distributed on the surface of the mesh plate 38. This technical solution can prevent the aluminum profile from blocking too many mesh holes and ensure that the mesh plate 38 has sufficient sand leakage capacity.

[0032] The upper end of the support column 333 is spherical in transition.

[0033] See also Figure 2 As shown, an inclined plate 334 is welded on the inner side of the sealing plate 33, and the end of the inclined plate 334 away from the sealing plate 33 is inclined downward, and the end of the inclined plate 334 is disconnected from the frame 31; the sand leaking from the mesh plate 38 slides down to the gathering surface 4 through the inclined plate 334.

[0034] In the above technical solution, the inclined plate 334 can receive part of the sand. When the frame 31 slides out, the sand falls into the sandblasting box 1 along the inclined plate 334, thereby reducing the leakage of sand.

[0035] See also Figure 1 and Figure 2 Vegetarian, an upper air duct 310 and a lower air duct 311 are installed on the outside of the closing plate 33, a connecting air duct 312 is provided between the upper air duct 310 and the lower air duct 311, a high-speed fan 313 is cooperated through the connecting air duct 312, the upper air duct 310 has two air outlet ends 314, the two air outlet ends 314 pass through the closing plate 33 and tilt downward, the lower air duct 311 has two first air outlet ends 315, the first air outlet ends 315 tilt downward and correspond to the inclined plate 334.

[0036] In the above technical solution, the airflow generated by the high-speed fan 313 blows the excess sand on the surface of the aluminum profile and the inclined plate into the sandblasting box before the frame 31 exits from the opening slot 101, thereby reducing the amount of sand carried out.

[0037] See also Figure 1 A return sand box 5 is installed on the ground, the discharge port is connected to the return sand box 5, an exhaust port is provided near the top of the outer wall of the return sand box, and a filter screen 51 is installed at the exhaust port.

[0038] The above technical solution can achieve exhaust and block sand.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
