[0024] Combination Figure 1-Figure 6 As shown, the utility model provides an air volume regulating device for a coating machine oven, comprising an air box upper cover 1, an upper air nozzle 2, a lower air nozzle 3, a deflector 4, a slide 5, a first regulating rod 6 and a second regulating rod 7; wherein,

[0025] The bellows upper cover 1 is provided with a slide groove 11, the upper air nozzle 2 and the lower air nozzle 3 are installed in the slide groove 11, and the upper air nozzle 2 is placed on the lower air nozzle 3. Specifically: the upper air nozzle 2 and the lower air nozzle 3 are stacked together and inserted into the slide groove 11 of the bellows upper cover 1; the contact surface of the upper air nozzle 2 and the lower air nozzle 3 is smooth, and the friction resistance is small, so that when the upper air nozzle moves, it will not drive the lower air nozzle to move; the contact surface of the lower air nozzle 3 and the bellows upper cover 1 is rough, and the friction resistance is large, which can make the position of the lower air nozzle in the groove relatively fixed; under the action of external force, the upper air nozzle 2 can slide in the slide groove 11, which is convenient for adjusting the size of the air outlet; two guide columns 8 are arranged on the upper air nozzle 2; a support plate 10 for supporting the No. 1 adjusting rod 6 and the No. 2 adjusting rod 7 is also provided on the bellows upper cover 1; the support plate 10 is arranged vertically, and the No. 1 adjusting rod 6 and the No. 2 adjusting rod 7 are connected to a hand wheel 9 after passing through the support plate 10;

[0026] The steering gear 4 includes a box body 41, an adjusting shaft 43 horizontally installed in the box body 41 through two No. 1 bearings 42, two bevel gears A44 fixed on the adjusting shaft 43, and two transmission rods 45 arranged on the side of the box body 41 close to the guide column 8 and respectively connected with the two bevel gears A44; the other end of the transmission rod 45 is threadedly connected to the guide column 8; the transmission rod 45 and the adjusting shaft 43 are in a vertical relationship; the rotating axis of the No. 1 adjusting rod 6 is rotated 90° through the steering gear 4; one end of the adjusting shaft 43 passes through the box body 41 and is connected to the No. 1 adjusting rod 6, and the other end of the No. 1 adjusting rod 6 is installed with a hand wheel 9; the hand wheel 9 on the No. 1 adjusting rod 6 is rotated to drive the adjusting shaft 43 and the bevel gear A44, and then the transmission rod 45 is rotated to realize the movement of the left and right positions of the upper air nozzle 2;

[0027] The slide 5 is arranged on the bellows upper cover 1, including a slide rail 51 and a slider 52 arranged on the slide rail 51, and the slider 52 is slidably connected to the slide rail 51; the diverter 4 is fixed on the slider 52; one end of the No. 2 adjusting rod 7 is connected to the slide 5, and the other end is also equipped with a hand wheel 9; a scale is provided on the outer edge of the hand wheel 9, and the scale corresponds to the relative displacement of the air outlet. Rotating the corresponding scale will cause the relative position of the upper air nozzle 2 and the lower air nozzle 3 to change accordingly.

[0028] Specifically, the transmission rod 45 is composed of a rotating shaft 451, a No. 2 bearing 452 and a bevel gear B453; the rotating shaft 451 is set on the box body 41 through the No. 2 bearing 452, and the rotating shaft 451 located inside the box body 41 is fixedly connected with the bevel gear B453 meshing with the bevel gear A44, and the rotating shaft 451 located outside the box body 41 is provided with an external thread threadedly connected to the guide column 8.

[0029] Further optimization scheme, the middle of the slide rail 51 is hollowed out, and the No. 2 adjustment rod 7 passes through the slide rail 51 horizontally. One end of the slide rail 51 is provided with an external thread, and a nut 53 is provided on the external thread, and the nut 53 is fixed under the slider 52; the No. 2 adjustment rod 7 is threadedly connected with the nut 53. A No. 3 bearing 54 is provided at the connection between the No. 2 adjustment rod 7 and the slide rail 51 to prevent the No. 2 adjustment rod 7 from moving; when the hand wheel 9 on the No. 2 adjustment rod 7 is turned, the No. 2 adjustment rod 7 will be driven to rotate, and the nut 53 is threadedly connected with the No. 2 adjustment rod 7. When the No. 2 adjustment rod 7 is fixed, the slider 52 connected with the nut 53 will move forward and backward, and the slider 52 is fixedly connected with the steering gear 4, and the slider 52 will drive the steering gear 4 to move, thereby driving the upper air nozzle 2 to move up and down.

[0030] According to a further optimization scheme, the shape, structure, position and size of the air outlet of the upper air nozzle 2 and the lower air nozzle 3 are the same. The shape and size of the air outlet are changed by changing the relative position of the air outlet of the upper air nozzle 2 and the lower air nozzle 3, thereby changing the air volume.

[0031] The utility model drives the upper air nozzle to move in four directions, front, back, left, and right, so that the relative position of the upper and lower air outlets of the air nozzle changes; because the positions and shapes of the upper and lower air outlets of the air nozzles are completely consistent, the change in the relative position of the upper and lower air outlets of the air nozzles causes the shape and size of the air outlets to change, thereby realizing the change of the air outlet volume of the air nozzle; the upper air nozzle and the lower air nozzle are stacked together and inserted into the slide groove of the bellows upper cover, and the inner surface of the slide groove is set to be rough, so that the friction resistance between it and the lower air nozzle is large, so that the position of the lower air nozzle in the slide groove can be fixed; the surface of the joint between the upper air nozzle and the lower air nozzle is set to be a smooth surface and there is a gap between them, so that when the upper air nozzle moves forward, backward, left, and right, it will not drive the lower air nozzle to move.

[0032] The utility model has little modification to the original oven structure, and only needs to adjust the original oven cover and air nozzle, install an adjustment mechanism and a support plate on the oven cover, install a guide column on the upper air nozzle, and add an air nozzle to adjust the air volume. Therefore, the utility model has a relatively broad application prospect.

[0033] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
