[0011] Optionally, a buffer surface is provided at the end of the protruding guide surface of the exhaust block, and the buffer surface is in the shape of a circular arc protrusion, and the buffer surface guides the paint to flow toward the filter screen.

[0012] By adopting the above technical solution, the buffer surface is in the shape of an arc protrusion, and the buffer surface guides the paint to flow toward the filter screen, so that the paint is not easily accumulated on the surface of the exhaust block facing the coating roller, further improving the stability of the paint flowing into the inner cavity of the storage box.

[0013] Optionally, the exhaust assembly also includes an elastic member 1, the exhaust block is slidably connected to the inner wall of the outlet air duct, one end of the elastic member 1 in the elastic direction is connected to the inner wall of the outlet air duct, and the other end of the elastic member 1 in the elastic direction is connected to the surface of the exhaust block, the elastic member 1 has an elastic force that drives the exhaust block to slide toward the direction close to the outlet air duct, and the inner wall of the outlet air duct tends to press against the surface of the exhaust block and close the exhaust air duct.

[0014] By adopting the above technical solution, the elastic force of the elastic member drives the exhaust block to slide in the direction close to the outlet air flow channel, and the inner wall of the outlet air flow channel presses against the surface of the exhaust block and closes the exhaust air flow channel. When the air pump is running, the air pressure in the outlet air flow channel continues to increase, and the air pressure in the outlet air flow channel drives the exhaust block to slide in the direction away from the exhaust air flow channel. The end of the exhaust block protrudes from the guide surface, and the opening of the exhaust air flow channel faces the filter.

The end of the sealing strip away from the connecting rod is pressed against the inner wall of the sealing cavity and separates the pipeline and the sealing cavity, so that the air pump stops supplying air to the sealing cavity. When the return plate slides along the inner wall of the storage box toward the return flow channel 2 under the pressure of the paint, the connecting rod receives the power of the return plate and drives the sealing strip to slide on the inner wall of the sealing cavity away from the pipeline. The separation effect of the sealing strip on the pipeline and the sealing cavity disappears, and the air pump drives the air to be stably injected into the sealing cavity through the pipeline, thereby realizing a stable air supply to the sealed cavity. At the same time, the surface of the sealing plate is pressed against the outer wall of the feed box and closes the sealing cavity, so that the air in the sealed cavity is not easy to overflow, thereby ensuring that the air in the sealed cavity is stably injected from the inlet flow channel into the outlet flow channel.

The sealing cavity 213 penetrates the feed box in the direction away from the pipeline. 21 outer wall, one end of the sealing strip 453 presses against the step surface 214 and separates the sealing cavity 213 and the inlet flow channel 211, the other end of the sealing strip 453 protrudes from the outer wall of the feed box 21 and is fixed to the end of the connecting rod 455, and the bottom wall of the storage box 42 is provided with a sliding cavity 422 for the sliding of the connecting rod 455, the sliding direction of the connecting rod 455 and the sliding direction of the return plate 451 are parallel to each other, and the end of the connecting rod 455 away from the sealing strip 453 passes through the sliding cavity 422 and is connected to the bottom of the return plate 451.

[0048] Reference Figure 5 and Figure 6 The sealing plate 454 is fixed to the end of the sealing strip 453 protruding from the feed box 21. The surface of the sealing plate 454 is pressed against the surface of the feed box 21 and closes the sealing cavity 213, so that the air in the sealing cavity 213 is not easy to overflow from the contact point between the surface of the sealing plate 454 and the surface of the feed box 21, thereby ensuring the stability of the air storage in the sealing cavity 213.

[0049] Reference Figure 5 and Figure 6When the return plate 451 slides along the inner wall of the storage box 42 toward the return flow channel 421, the connecting rod 455 receives the power of the return plate 451 and drives the sealing strip 453 to slide in the direction away from the pipeline. The pipeline is connected to the sealing cavity 213 through the inlet flow channel 211. The air pump 431 drives the air through the pipeline to pass through the inlet flow channel 211 and the sealing cavity 213 in turn and enter the outlet flow channel 412 from the inlet flow channel 211, thereby realizing the directional start-up of the air pump 431 and reducing the energy loss, thereby reflecting the concept of energy saving.

[0050] Reference Figure 5 The bottom wall of the feed box 21 is rotatably connected to a stirring impeller 6, which drives the paint in the feed box 21 to flow, so that the paint in the feed box 21 is not easy to settle. At the same time, the end of the rotating shaft of the stirring impeller 6 passes through the bottom wall of the feed box 21 and is located in the sealed cavity 213. The rotating shaft of the stirring impeller 6 located in the sealed cavity 213 is coaxially installed with a transmission impeller 7; when the air in the sealed cavity 213 enters the inlet air flow channel 211, it impacts the blades of the transmission impeller 7, driving the transmission impeller 7 to rotate, driving the stirring impeller 6 to rotate on the bottom wall of the feed box 21, and no external power device is required to drive the stirring impeller 6 to rotate, thereby reducing energy loss, thereby embodying the concept of energy saving.

[0051] The implementation principle of a horizontal coating machine in an embodiment of the present application is as follows: the transmission motor 53 runs, driving the substrate on the active roller 51 to be coated with paint through the coating roller 31 in turn, and the scraper 32 adjusts the coating thickness and then winds it around the roller surface of the driven roller 52, thereby improving the processing accuracy of the coating on the substrate. At the same time, the scraping end of the scraper 41 presses against the roller surface of the coating roller 31 and scrapes off the residual paint on the surface of the coating roller 31, thereby cleaning the surface of the coating roller 31, making it difficult for the paint to accumulate on the roller surface of the coating roller 31, and making the surface of the substrate evenly coated with paint to form a coating, thereby improving the processing accuracy of the substrate coating.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
