[0020] Furthermore, a vertically arranged slide rail 3 is respectively provided on both sides of the opening, and the movable door includes a folding door 5. A slider 4 is respectively provided on both sides of the bottom of the folding door 5, and the slider 4 is slidably connected to the corresponding slide rail 3.

[0021] Furthermore, the driving mechanism includes a cylinder 10 , a cylinder body of the cylinder 10 is connected to the box body 1 , and an end of a piston rod of the cylinder 10 is connected to one of the sliders 4 .

[0022] Furthermore, the folding door 5 is made of rubber. Furthermore, the bracket 6 comprises a central block, on which three support rods extending horizontally outward are arranged, and a limiting column is arranged on the upper surface of the outer end of each support rod.

[0023] Furthermore, the support beam 7 is a cross-shaped support beam 7 , and the end of the cross-shaped support beam 7 is connected to the inner wall of the box body 1 .

[0024] When the utility model is working, it can cooperate with the manipulator or be operated manually. The manipulator or the manual operator puts the processed workpiece on the bracket 6 in the box body 1, so that the limit columns of the three support rods are located on the inner side of the gear ring, and then the manipulator withdraws from the box body 1, and the controller controls the driving mechanism to close the movable door. In this embodiment, the slider 4 of the folding door 5 is driven by the cylinder 10 to move downward along the slide rail 3, so that the folding door 5 is unfolded to achieve the effect of closing the door. After closing the door, the controller starts the solenoid valve, and the compressed air is introduced through the air inlet pipe 94. The compressed air enters the annular air cavity 92 of the jet head 91, and then sprays out from the annular air outlet 93 at the top. Since the annular air jet hole sprays air toward the workpiece, the impurities such as iron filings and dust on the surface of the workpiece are blown away. At the same time, the fan 2 at the top of the box body 1 blows air downward, blowing the impurities in the box body 1 to the ventilation port below, so that the impurities are discharged from the box body 1. After blowing for a period of time, the controller controls the solenoid valve to close, stop ventilation, and control the driving mechanism to open the movable door. At this time, the manipulator or the worker can take out the workpiece for inspection.
