According to the width of the part to be coated, the worker can translate the left door 507 and the right door 508 through the translation mechanism, thereby adjusting the width of the inlet and outlet, and reducing the amount of air entering from the inlet and outlet.

In addition, as shown in FIG. 6 , the width of the inlet and the width of the outlet gradually increase from top to bottom, so as to reduce the amount of air entering the lower part of the inlet and the outlet.

In order to further reduce the air entering the main body of the powder booth through the outlet and the inlet, as shown in FIG. 6 , the inlet and the lower part of the outlet are also provided with reels, and the reels are provided with a roll-up door cloth 510 , and the roll-up door cloth There are sliders on both sides of 510, the two sliders are connected by a sliding rod 511, and the rolling door cloth 510 is connected with the sliding rod 511; the left door 507 and the right door 508 are respectively provided with vertical slideways, so The sliding block is adapted to the vertical slideway; the vertical slideway is provided with a sliding block fixing member for fixing the sliding block, and the sliding block fixing member is used for fixing the sliding block and then fixing the roll door cloth 510. The above-mentioned reel can be used to roll up or release the roll-up door cloth 510. In specific use, the staff can arrange the roll-up door cloth 510 at the entrance or outlet from bottom to top as required to prevent air from entering the main body of the powder room from the lower part of the entrance and the lower part of the outlet. Finally, the air pressure in the lower part of the main body of the powder room is low, the air pressure in the upper part is high, and the air flows downward from the upper part, so as to collect the powder dispersed in the air, and also reduce the density of the powder in the air in the space where the staff is located. And prevent the powder from overflowing from the upper part of the powder spraying room.

More specifically, in this embodiment, in order to make the post-spraying position 503 at the upwind position, to improve the working environment of the staff, and also to better collect the powder dispersed in the post-spray chamber 502, in this embodiment, , air entry from the top wall slot 504 should be minimized. To this end, in this embodiment, flexible members are respectively provided on both side walls of the slot 504, and the hanging chain 35 passes between the two flexible members. The above-mentioned flexible members can be used for blocking Slots 504 prevent air from entering the main body of the powder booth from the slot 504, so that more air enters from the upper parts of the two ends of the main body of the powder booth, thereby forming an airflow flowing from the upper parts of the two ends to the powder recovery port. The recovery port makes it easier to collect the powder in the main body of the powder room, especially the powder in the air of the supplementary spraying room 502; in addition, the supplementary spraying position 503 can be placed at the upper air outlet, which improves the working environment of the staff. In addition, compared with the air entering directly from the upper slot 504, the air flows downward obliquely from both ends, which has less influence on the powder spraying, which can avoid uneven powder spraying on the upper and lower parts of the powder spraying part when the air flows directly downward. The problem.

Wherein, the above-mentioned flexible member may already exist in the following form. The flexible member includes a sponge, and the sponge is pasted and fixed on both side walls of the slot 504; the sponge is covered with a cloth sheet, and the cloth sheet is Set with fluff. The above-mentioned sponge has high elasticity, and has little resistance to the movement of the hanging chain 35;

More specifically, as shown in FIG. 7 , in order to prevent the air from entering the main body of the powder booth from the slot 504, another implementation method in this embodiment can also be used. The top wall of the main body of the powder booth is provided with two rotating The rotating assembly includes a driving wheel, a driven wheel and a rotating ring, the driving wheel is connected with a servo motor, and the rotating ring is sleeved on the driving wheel and the driven wheel. The two rotating rings are mirror-symmetrical with the slot 504 as the central axis, and a plurality of rubber sheets 513 are arranged on the rotating rings; the rubber sheets 513 on the two rotating rings abut and cover the openings. Slot 504. In the above solution, the driving wheel and the driven wheel drive the rotating ring to move, and the abutting surfaces of the two rotating rings move in the same direction, that is, the abutting rubber sheets 513 move in the same direction. The above-mentioned rubber sheet 513 covers the slot 504, which can prevent air from entering the main body of the powder booth from the slot 504. When the powder-spraying part moves, the hanging chain 35 moves in the groove 504, and the rubber sheet 513 follows the hanging chain 35. Of course, in order to keep the movement of the rubber sheet 513 consistent with the movement of the hanging chain 35, the rotation speed of the above-mentioned servo motor should be consistent with the movement speed of the accumulating and releasing chain 1 of the hanging chain 35. The rubber sheet 513 can not only prevent the air from entering from the slot 504 to realize the movement of the air flow from the upper part of the two ends of the main body of the powder room to the powder recovery port, but also can clamp the hanging chain 35 to prevent the hanging chain 35 from swinging, so as to improve the powder spraying efficiency. stability. The above-mentioned rotating rings are arranged as follows: each rotating ring is provided with a plurality of rubber sheets 513 ; At the same time, there are a plurality of rubber sheets 513, and the rubber sheets 513 can be closely distributed one by one. When the rubber sheets 513 run to the changing position of the driving wheel or the driven wheel, the rubber sheets 513 can be separated; and when the rubber sheets 513 have And when there is only one and the ring is fixed on the rotating ring, the rubber sheet 513 will inevitably be stretched and deformed when it runs to the driving wheel or the driven wheel. There are multiple rubber sheets 513, and the rubber sheet 513 runs to the driving wheel or the driven wheel. can be separated when the above situation can be avoided.

Of course, the above descriptions are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Under the inventive concept of the present invention, any equivalent structural transformation made by using the contents of the description and accompanying drawings of the present invention, or directly/ Indirect applications in other related technical fields are included in the scope of patent protection of the present invention, and should be protected by the present invention.
