Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. For example, the fixed connection / installation can be connected by screws, bolts and other accessories, or it can be directly connected by welding, bonding and other methods. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0029] Reference Figure 1 and Figure 2 The embodiment of the utility model provides a coating device, including a wall panel 1 and a primer coating mechanism 2, a micro-concave coating mechanism 3 and a roller mechanism 4 installed on the wall panel 1. The substrate (diaphragm 5) is supported and transmitted by the roller mechanism 4, and is coated by the primer coating mechanism 2 and the micro-concave coating mechanism 3 in sequence, that is, the main slurry is first coated on the substrate (diaphragm 5) by the coating mechanism, and then the ceramic slurry is coated on the edge coating area of ​​the diaphragm 5 by the micro-concave coating mechanism 3. Since the main slurry of the diaphragm 5 is thinner after the primer coating process, the ceramic slurry coated by the micro-concave coating process is also thinner. The coating thickness of the conventional coating method is 30-40μm, while the coating thickness of the coating method of the utility model is 5-10μm, thereby avoiding the problems of dark marks in the overlapping area after baking and bulging ribs in the ceramic area during winding.

[0030] In this embodiment, refer to Figure 2 The primer mechanism 2 includes a plate roller 21, a plate roller motor, a rubber pressure roller 22, a rubber pressure roller driving unit 23, a primer tank 26 and a material tank driving unit 27. The rubber pressure roller 22 is arranged directly above the plate roller 21. The substrate is primed when passing between the plate roller 21 and the rubber pressure roller 22. The rubber pressure roller driving unit 23 includes a rubber pressure roller 22 lifting cylinder. The rubber pressure roller 22 lifting cylinder is fixed on the wall panel 1, and the piston rod of the rubber pressure roller 22 lifting cylinder is connected to the end of the rubber pressure roller 22. When the rubber pressure roller 22 lifting cylinder is extended and retracted, it can drive the rubber pressure roller 22 to move, thereby driving the rubber pressure roller 22 to approach or move away from the plate roller 21, so as to adjust the distance between the rubber pressure roller 22 and the plate roller 21, thereby realizing the adjustment of the coating pressure of the diaphragm 5 during primer coating.

[0031] Further, the primer tank 26 is used to provide the main slurry to the plate roller 21. The primer tank 26 is located at the bottom of the plate roller 21, and a part of the plate roller 21 is located in the primer tank 26, that is, the plate roller 21 is immersed in the main slurry of the primer tank 26, and the plate roller motor drives the plate roller 21 to rotate to apply the main slurry on the diaphragm 5. Preferably, the primer tank 26 is connected to the material tank driving unit 27, and the material tank driving unit 27 includes a rack, a gear and a gear motor. The rack is slidably connected to the wallboard 1 in the vertical direction, and the gear motor is fixedly installed on the wallboard 1 and drives the gear to rotate. The gear is meshed with the rack, and the top of the rack is connected to the primer tank 26. When the gear motor drives the gear to rotate, it drives the rack to move up and down, thereby driving the primer tank 26 to approach or move away from the plate roller 21 to adjust the amount of the main slurry of the plate roller 21 immersed in the primer tank 26.

[0032] In some embodiments, reference Figure 2 The primer mechanism 2 also includes a primer scraper 24 and a scraper operating component 25. When the primer scraper 24 abuts against the roller surface of the plate roller 21, the scraper operating component 25 is used to drive the primer scraper 24 to move closer to or away from the plate roller 21 to adjust the degree to which the primer scraper 24 scrapes the slurry on the plate roller 21.

[0033] In this embodiment, refer to Figure 2 and Figure 3 The micro-concave coating mechanism 3 includes a mounting frame 35, a micro-concave roller assembly, a scraper assembly 32 and a trough assembly 33.

The surface of the flange 312 is provided with micro pits. When the flange 312 is immersed in the ceramic slurry in the main trough 331 of the trough assembly 33, a layer of ceramic slurry can adhere to the surface of the flange 312 for easy coating; the micro-concave roller power unit 34 adopts a servo motor and is connected to the end of the roller body 311 through a reducer, so as to drive the roller body 311 to rotate. When the roller body 311 rotates, the flange 312 coats the ceramic slurry on the edge coating area of ​​the diaphragm 5.

[0034] Furthermore, the trough assembly 33 is located below the micro-concave roller 31 and is used to provide ceramic slurry to the micro-concave roller 31.

An overflow port 333 is provided on the main trough 331, and the main trough 331 is connected to the return trough 332 through the overflow port 333. The main trough 331 is provided with ceramic slurry through an external slurry feeding system, and the return trough 332 is provided with a slurry outlet and connected to the slurry feeding system, so that when there is too much ceramic slurry in the main trough 331, the ceramic slurry flows into the return trough 332 through the overflow port 333, and then flows back to the slurry feeding system, thereby effectively avoiding leakage of ceramic slurry, and there is no need to install a liquid level sensor to monitor the liquid level. The slurry feeding system can continuously feed the main trough 331, effectively saving costs.

Therefore, when the height adjustment screw 334 is rotated, the return material trough 332 can be driven to move up and down based on the mounting frame 35, so that the main material trough 331 is close to or away from the micro-concave roller 31 to adjust the amount of slurry immersed in the micro-concave roller 31.

[0036] In this embodiment, refer to Figure 6 The scraper assembly 32 includes a scraper and a scraper driving unit. Specifically, the scraper includes a scraper fixing plate 324 and a front scraper 321 and a side scraper 322 connected to the scraper fixing plate 324.

[0037] Furthermore, the scraper drive unit includes a cylinder mounting plate 326 and a telescopic cylinder 327, the telescopic cylinder 327 is installed on the cylinder mounting plate 326, and the movable end of the telescopic cylinder 327 is connected to the scraper fixing plate 324.

When the telescopic cylinder 327 is extended or retracted, the connecting rod 325 is driven to rotate, thereby driving the scraper fixing plate 324 to move. When the scraper fixing plate 324 moves, it drives the front scraper 321 to approach or move away from the surface of the flange 312, so as to achieve the adjustment of the amount of slurry scraped by the front scraper 321 on the surface of the flange 312.

[0038] Furthermore, a parallel finger cylinder 323 is provided on the scraper fixing plate 324, and the two side scrapers 322 are respectively installed on the two movable ends of the parallel finger cylinder 323, so that when the parallel finger cylinder 323 is running, the two side scrapers 322 are driven to clamp or release the flange 312, so as to realize the adjustment of the scraping amount of the side of the flange 312 by the side scraper 322.
