[0002] A coater is a device used to evenly apply a coating to a material's surface. It is widely used in the processing of substrates such as paper, plastic film, fabric, and metal foil. Coating machines can be categorized into various types based on the application, coating method, and material properties. Existing coating machines include blade coaters, roll coaters, extrusion coaters, gravure coaters, air knife coaters, slot coaters, hot melt coaters, dip coaters, spray coaters, and screen coaters. Spray coaters utilize high pressure to atomize the coating through a nozzle and evenly apply it to the substrate surface, making them suitable for rapid and uniform coating of large areas. Roller coaters, on the other hand, utilize contact between the roller and the substrate to evenly apply the coating. Depending on the roller structure and configuration, three-roll and four-roll coating methods are common. These are widely used in coating films, paper, and fabrics, as well as packaging materials, battery materials, and adhesive tapes.

[0032] See also Figure 1 The utility model discloses a coating structure 10 of a coating machine, which includes a base 100, a spraying mechanism 200 and a roller coating mechanism 300. The spraying mechanism 200 and the roller coating mechanism 300 are both arranged on the base 100, wherein the spraying mechanism 200 is arranged on the top side of the base 100, and the roller coating mechanism 300 is arranged at both ends of the base 100. Therefore, when the material to be coated is transported from the top side of the base 100, the spraying mechanism 200 sprays the surface of the material, and the roller coating mechanism 300 rolls the coating sprayed on the surface of the material evenly, thereby achieving uniform coating treatment on the surface of the material. Specifically, the spraying mechanism 200 includes a first spraying assembly 210 and a second spraying assembly 220. The first spraying assembly 210 is disposed on the top surface of the base 100 and extends along the length of the base 100, thereby enabling the first spraying assembly 210 to spray the material conveyed through the surface of the base 100. The second spraying assembly 220 is disposed on the top side of the first spraying assembly 210, and the output end of the second spraying assembly 220 can move along a preset trajectory relative to the base 100, thereby enabling the spraying of specific parts of the material. After the material is sprayed, it is evenly coated by the roller coating mechanism 300.

[0033] Furthermore, the roller coating mechanism 300 includes a first roller assembly 310 and a second roller assembly 320, respectively disposed at opposite ends of the base 100. While the material is being conveyed through the first and second roller assemblies 310, 320, the first roller assembly 310 and the second roller assembly 320 work together to evenly coat the material surface with coating. Specifically, the first spray assembly 210 is disposed between the first and second roller assemblies 310 and 320. In practice, the first roller assembly 310 drives the material along the top surface of the base 100 to the second roller assembly 320. During this process, the first and second spray assemblies 210 and 220 spray the coating onto the material surface. Subsequently, the second roller assembly 320 rolls the coating evenly onto the material surface, completing the coating.

[0034] Furthermore, the first spraying assembly 210 includes a first drive unit 211, a first track 212, and a first spraying unit 213.

The first spraying unit 213 is capable of reciprocating along the first track 212, allowing an operator to adaptively adjust the relative position of the first spraying unit 213 based on actual coating processing requirements. The first drive unit 211 can provide power to the first track 212, thereby achieving automatic adjustment of the first spraying unit 213. Specifically, the first drive unit 211 also drives and connects to the first roller assembly 310 and the second roller assembly 320, thereby synchronizing the rotation of the first roller assembly 310 and the second roller assembly 320 to coat the surface of the material. In one embodiment, the first drive unit 211 is drivingly connected to the second roller set 320, and the second roller set 320 is drivingly connected to the first roller set 310 via a transmission mechanism, so that the first drive unit 211 can synchronously drive the first roller set 310 and the second roller set 320 to rotate. In one embodiment, the first drive unit 211 is configured as a servo motor.

[0035] Furthermore, the second spraying assembly 220 includes a second drive unit 221, a second track 222, a third drive unit 223, and a second spraying unit 224. The second drive unit 221 is mounted on the top side of one end of the base 100; the second track 222 is mounted on the top side of the other end of the base 100 relative to the second drive unit 221; one end of the third drive unit 223 is connected to the output end of the second drive unit 221, and the other end of the third drive unit 223 is slidably engaged with the second track 222, so that the third drive unit 223 can reciprocate along the second track 222 under the drive of the second drive unit 221; the second spraying unit 224 is connected to the output end of the third drive unit 223, so that the second spraying unit 224 can move biaxially relative to the base 100, thereby expanding the spraying range of the second spraying unit 224 on the material surface. In one embodiment, the second drive unit 221 is configured as a linear slide; in one embodiment, the third drive unit 223 is configured as a linear slide.

[0036] Furthermore, the second spraying assembly 220 also includes a rotating motor 225, which is connected to the output end of the third driving unit 223, and the output end of the rotating motor 225 drives the second spraying unit 224, so that the second spraying unit 224 can rotate according to the spraying requirements during the actual working process, thereby improving the versatility of the second spraying unit 224.

[0037] Furthermore, the base 100 is provided with a first mounting bracket 110 and a second mounting bracket 120. The first mounting bracket 110 is provided on the top side of one end of the base 100, corresponding to the second drive unit 221; the second mounting bracket 120 is provided on the top side of the other end of the base 100, corresponding to the second track 222. Specifically, the second drive unit 221 is mounted on the top surface of the first mounting bracket 110; at the same time, the second track 222 is mounted on the top surface of the second mounting bracket 120, thereby effectively ensuring the installation stability of the second spray assembly 220.

[0038] Furthermore, the first spray assembly 210 is configured with two first rails 212 and two first spray units 213. The two first rails 212 are respectively disposed on either side of the base 100 along the length of the base 100. The two first spray units 213 are respectively slidably connected to the two first rails 212, thereby further expanding the spraying range of the first spray assembly 210. Specifically, the output end of the first drive unit 211 is respectively driven and connected to the two first rails 212, thereby simultaneously driving the two first spray units 213 to reciprocate along the corresponding first rails 212.

[0039] In summary, the coating structure of the coating machine disclosed in the present invention sprays the surface of the material through a spraying mechanism, and the roller coating mechanism rolls the coating sprayed on the surface of the material to make it uniform, thereby achieving uniform coating treatment on the surface of the material. Specifically, the spraying mechanism includes a first spraying component and a second spraying component. The first spraying component is arranged on the top side surface of the base, and the first spraying component is extended along the length direction of the base, so that the first spraying component can spray the material transported through the surface of the base; the second spraying component is arranged on the top side of the first spraying component, and the output end of the second spraying component can move along a preset trajectory relative to the base, so that specific parts of the material can be sprayed.
