Description

Technical Field

[0001] This utility model relates to the field of microgravure roller structure technology, specifically, to a microgravure roller structure for coating. Background Technology

[0002] The coating microgravure roller structure, which consists of a microgravure roller, a feed tray, and a liquid injection port, is a key component widely used in coating processes. It is usually a metal roller with a precision-machined surface engraved with tiny pits or grooves. The shape, size, and depth of these pits and grooves are all at the micrometer level.

[0003] The coating micro-gravure roller structure is used in operation. The micro-gravure roller is partially immersed in the feed tray. The rotating shaft drives the micro-gravure roller to rotate, which carries the coating. After being metered by the flexible doctor blade, the coating liquid is carried away by the substrate moving in the opposite direction, achieving uniform thin-layer coating. The roller surface is engraved with cavities, which control the amount of adhesive transferred from the glue tray. The doctor blade removes excess material, and the remaining material in the cavities is transferred to the substrate in a certain proportion.

[0004] In traditional microgravure roller structures, the paint carries some dust and other impurities during the process of being injected into the paint tray. As a result, when the paint is subsequently carried up by the microgravure roller, the dust and impurities in the paint can easily adhere to the pores of the microgravure roller, causing blockage and affecting the uniformity of the paint application.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a micro-gravure roller structure for coating, including a roller 1, with a feeding tray 11 rotatably connected to both ends of the roller 1, and a feeding port 12 fixedly connected to one end of the feeding tray 11. A filter screen 13 is fixedly connected to the inner side of the feeding port 12 near the feeding tray 11. A protective component 2 is provided at the outer end of the roller 1, and the protective component 2 includes a ceramic coating 21 fixedly connected to the outer side of the middle end of the roller 1. A nano-surface treatment layer 22 is fixedly connected to the end of the ceramic coating 21 away from the roller 1. Furthermore, a rotating component 3 is provided inside the injection port 12, a power component 4 is provided at one end of the rotating component 3, and a plug-in component 5 is provided inside the rotating component 3. A locking component 6 is provided at both ends of the plug-in component 5, and a cleaning component 7 is provided on the outer side of the middle end of the plug-in component 5. Through the cooperation of the protective component 2 and the rotating component 3, the paint injected into the feeding tray 11 can be filtered, thereby reducing the impurities carried by the paint in the feeding tray 11, thus preventing the holes on the outside of the roller 1 from being blocked, and effectively improving the uniformity of the paint.

[0025] like Figure 3 As shown, the rotating assembly 3 includes a gear ring 31 rotatably connected to the inner side of one end of the injection port 12 via a flange, and a first connecting plate 32 is fixedly connected to the inner sides of both ends of the gear ring 31. The gear ring 31 drives the first connecting plate 32 to rotate by meshing with the gear of the gear ring 31 using the gear 41.

[0026] like Figure 3 and Figure 4As shown, the power assembly 4 includes a gear 41 that meshes with the outer gear of one end of the gear ring 31, and a housing 42 is sleeved on the outer side of the gear 41. The end of the housing 42 near the injection port 12 is fixedly connected to the injection port 12, and a motor 43 is fixedly connected to the outer side of the housing 42. The output shaft of the motor 43 passes through the housing 42 and is fixedly connected to the gear 41. The operation of the motor 43 drives the gear 41 to rotate under the protection of the housing 42.

[0027] like Figure 5 As shown, the plug-in assembly 5 includes a second connecting plate 51 inserted into the inner side of the first connecting plate 32 away from the toothed ring 31, and plug plates 52 are fixedly connected to both ends of the second connecting plate 51. The end of the plug plate 52 away from the second connecting plate 51 is inserted into the first connecting plate 32. The rotating rod 71 and the like can be installed using the second connecting plate 51 and the plug plate 52.

[0028] like Figure 4 and Figure 5 As shown, the carding assembly 6 includes a carding plate 61 that fits against the outside of the insert plate 52, and a spring 62 is fixedly connected to one end of the carding plate 61 that is inserted into the first connecting plate 32. The end of the spring 62 that is away from the carding plate 61 is fixedly connected to the first connecting plate 32. The carding plate 61 can be moved by the push plate 63 so that it is inserted into the first connecting plate 32 to compress the spring 62.

[0029] like Figure 4 As shown, a push plate 63 is fixedly connected to the outer side of the end of the card plate 61 near the spring 62, and the push plate 63 is set in a trapezoidal shape.

[0030] like Figure 4 As shown, the cleaning assembly 7 includes a rotating rod 71 fixedly connected to the outer side of the middle of the second connecting plate 51, and a third connecting plate 72 fixedly connected to the end of the rotating rod 71 away from the second connecting plate 51. A cleaning brush 73 is fixedly connected to the end of the third connecting plate 72 away from the rotating rod 71, and the side of the cleaning brush 73 away from the third connecting plate 72 is in contact with the filter screen 13. The rotation of the rotating rod 71 drives the third connecting plate 72 and the cleaning brush 73 to rotate, thereby cleaning the dust and other particles attached to the surface of the filter screen 13 by the rotation of the cleaning brush 73.

[0031] Working principle: When filtering the paint in the feed tray 11, the paint is first injected into the feed tray 11 through the injection port 12. Then, the injected paint is filtered through the filter screen 13. Next, the motor 43 is started. After the motor 43 starts, its output shaft, protected by the housing 42, drives the gear 41 to rotate. The rotating gear 41 meshes with the gear ring 31, causing the gear ring 31 to drive the first connecting plate 32 to rotate. The rotation of the first connecting plate 32 then drives the second connecting plate 51 to rotate through the insert plate 52. The rotation of the second connecting plate 51 synchronously drives the rotating rod 71, the third connecting plate 72, and the cleaning brush 73 to rotate. The rotation of the cleaning brush 73 then cleans the impurities adhering to the surface of the filter screen 13. The rotating rod needs to be cleaned afterward. 71. When replacing the third connecting plate 72 and the cleaning brush 73, push the push plate 63 to move the clamping plate 61 and compress the spring 62. Then pull the second connecting plate 51 to pull out the first connecting plate 32, thereby removing the third connecting plate 72 and the cleaning brush 73. Then insert the second connecting plate 51 and the clamping plate 52 into the first connecting plate 32. During the insertion of the clamping plate 52, the clamping plate 61 is squeezed. After the insertion of the clamping plate 52 is completed, the clamping plate 61 is pushed out by the elastic potential energy of the spring 62. The clamping plate 61 is used to fix the clamping plate 52 in place. At the same time, the ceramic coating 21 and the nano surface treatment layer 22 are used to protect the holes on the roller 1, effectively preventing the adhesion of dust and other substances.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
