[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] The utility model provides an air volume regulating device for a coating machine, comprising a frame 1, wherein a coating roller 101 is rotatably connected to the frame 1, a base 2 is fixedly connected to the right side of the frame 1, a bracket 201 is slidably connected to the base 2, a bellows 3 is fixedly connected below the bracket 201, a turbo fan 301 is installed in the bellows 3, and the turbo fan 301 has its own power supply, small holes 302 are evenly distributed on the right wall of the bellows 3, and the structural design of the small holes 302 ensures that the bellows 3 can contact with the outside air in the later stage so that the wind can be blown out, a slide groove 202 is arranged in the base 2, the bracket 201 can be slidably arranged in the slide groove 202, a cylinder 4 is also fixedly connected to the slide groove 202, a slide rod 401 is slidably connected to the cylinder 4, and the slide rod 401 is fixedly connected to the bracket 201, a conical opening 303 is arranged on the left side of the bellows 3, and a partition plate 5 is slidably connected to the bellows 3, so that the air volume blown out can be controlled;

[0020] When the air volume regulating device of the coating machine is actually used, the turbo fan 301 in the bellows 3 cooperates with the built-in power supply to complete the continuous output of air by the bellows 3. When the required air volume of the coating machine needs to be adjusted, the cylinder 4 first drives the slide bar 401 to extend and retract left and right in the slide slot 202. The slide bar 401 and the bracket 201 are fixedly connected. The slide bar 401 cooperates with the bracket 201 to drive the bellows 3 to slide left and right on the right side of the coating roller 101. When the preset air volume output position is reached, the cylinder 4 stops working. At this time, the staff manually operates the pull plate 501 to drive the partition plate 5 to slide in the bellows 3 until the pull plate 501 and the positioning plate 50 are adjusted according to the required air volume. Then, the staff manually operates the bolt 503 to pull the pull plate 501 and the positioning plate 50 2 are fixed between them, so that the air volume output by the bellows 3 is consistent with the required air volume, thereby ensuring the orderly progress of normal coating work. By installing a base 2 on the right side of the frame 1, and then setting a bracket 201 structure that can slide left and right on the base 2, a bellows 3 is installed under the bracket 201, so that the overall structure of the bellows 3 can slide left and right under the drive of the bracket 201. Compared with the conventional fixed bellows 3 structural design, the mobile bellows 3 structure adopted in the utility model can be adaptively adjusted according to the size of the real-time required air volume, thereby improving the flexibility of the overall structure. A slidable and adjustable partition 5 structure is set on the bellows 3, so that the air volume blown out in the wind direction can be adjusted again, thereby ensuring the coating quality processed by the coating machine.

[0021] like Figure 1-2 As shown, a pull plate is fixedly connected to the partition, a positioning plate is fixedly connected to the bellows, the pull plate and the positioning plate are connected by bolts, and a plurality of mounting holes are evenly distributed on the positioning plate.

[0022] The effect achieved by the entire embodiment 1 is that, during use, by installing the mounting holes on the positioning plate, the staff can adaptively adjust the output air volume according to the required different air volume sizes.

[0023] Working principle: The turbo fan in the bellows cooperates with the built-in power supply to complete the continuous output of air from the bellows. When the required air volume of the coating machine needs to be adjusted, the cylinder first drives the slide bar to extend and retract left and right in the slide slot. The slide bar and the bracket are fixedly connected. The slide bar cooperates with the bracket to drive the bellows to slide left and right on the right side of the coating roller. When it reaches the pre-set air volume output position, the cylinder stops working. At this time, the staff manually operates the pull plate to drive the partition to slide in the bellows until it reaches the required air volume. The staff then manually operates the bolts to fix the pull plate and the positioning plate, so that the air volume output by the bellows is consistent with the required air volume, ensuring the orderly progress of normal coating work.
