Description

Technical Field

[0001] The utility model relates to the field of optical film coating, in particular to a micro-concave coating roller. Background Art

[0002] At present, micro-concave roller coating has been widely used in display-related functional layer coating, including anti-fingerprint hard coating, anti-glare layer, anti-reflection layer, etc., because of its suitability for low viscosity and thin layer coating characteristics, high precision, good repeatability, simple coating method and easy operation. Micro-concave roller coating mainly uses a diameter of 40-60mm, with different shapes of patterns and mesh numbers engraved on the surface. The micro-concave roller is immersed in the coating tank, and the coating liquid is brought on by the grooves in the micro-concave roller. The excess coating liquid is scraped off with a scraper and transferred to the substrate by reverse kiss coating. There are four main types of texture shapes: pyramid, quadrilateral, oblique line and hexagonal. The appropriate texture shape is selected according to the characteristics of the coating liquid. The mesh number ranges from 30 to 250. Each mesh number represents a different coating amount. The larger the mesh number, the lower the coating amount. When trial coating a product, first select different texture shapes, then select a matching texture shape based on the appearance after coating, then test coat with different mesh sizes based on the selected texture shape to find the mesh size corresponding to the designed thickness. Therefore, micro-concave rollers of various shapes and mesh sizes are needed to meet the needs of new product development. This is not only inefficient, but also increases costs for manufacturers.

[0003] Chinese patent publication number CN103861769B discloses "a micro-concave coating device". On the basis of the original blocking device, a secondary blocking device is added. The main purpose is to prevent the scraper on the primary blocking device from being used for a long time, causing serious wear and tear, and causing defects on the scraper surface, causing the slurry to be transferred to the material to be coated (collector, isolation membrane, etc.) through the scraper surface defects, resulting in uneven coating and other phenomena; after adding the secondary blocking device, the surface defects of the gravure roller can be repaired again, the product defect rate can be reduced, and the equipment maintenance rate (such as replacement of scrapers, debugging time, etc.) can be reduced; the excess slurry blocked by the secondary blocking device is connected to the supply barrel through the return port and recycled again.

[0004] During the conception process, the applicant searched a large number of patent documents on the patent network. For example, Chinese patent publication number CN103861769B discloses "a micro-concave coating device". When the micro-concave coating device is used for the first time in the development of new products, due to the matching of the coating liquid and the micro-concave roller shape, as well as the coating thickness design requirements, the micro-concave roller needs to be frequently replaced for testing. When the test effect meets the requirements, the coating operation is carried out, which leads to the problems of complicated work flow, low work efficiency and high cost. Therefore, a micro-concave coating roller is proposed to solve the above-mentioned problems. Utility Model Content

The patterns on the surface of the gravure roller 1 can be provided with four to five kinds, the engraving widths of the pyramid-shaped texture 11, the quadrilateral texture 12, the diagonal texture 13, and the hexagonal texture 14 are all 100 mm to 600 mm, and the mesh number ranges of the pyramid-shaped texture 11, the quadrilateral texture 12, the diagonal texture 13, and the hexagonal texture 14 are all 30 to 250, The diameter of the gravure roller 1 is 40 mm to 60 mm, and the length of the gravure roller 1 is 500 mm to 2500 mm. When the gravure roller 1 rotates, it drives the pyramid-shaped texture 11, the quadrilateral texture 12, the oblique-shaped texture 13, and the hexagonal texture 14 to rotate, so that the pyramid-shaped texture 11, the quadrilateral texture 12, the oblique-shaped texture 13, and the hexagonal texture 14 respectively apply the corresponding textures to the material; connecting shafts 2 are respectively installed on both sides of the gravure roller 1, and a mounting shaft 3 is arranged at one end of the connecting shaft 2 away from the gravure roller 1; a mounting component 4 is used for quickly installing the gravure roller 1, and the mounting component 4 is arranged on the connecting shaft 2. The invention comprises a rebounder 41, which is mounted on the inner wall of the connecting shaft 2. The end of the rebounder 41 away from the connecting shaft 2 is connected to a mounting plate 42, three limit pins 43 are connected to the mounting plate 42, two No. 1 inclined plane blocks 44 are connected to the mounting plate 42, three round holes and two square holes are opened on the mounting shaft 3, the two square holes are located on the movement trajectory of the two No. 1 inclined plane blocks 44, the three round holes are located on the movement trajectory of the three limit pins 43, the side length of the No. 1 inclined plane block 44 is greater than the round hole, the gravure roller 1 is pressed downward, the gravure roller 1 drives the two connecting shafts 2 to move downward, the connecting shaft 2 drives the mounting plate 42 to move downward through the rebounder 41, and the mounting plate 42 drives the two No. 1 inclined plane blocks 44 and the three limit pins 43 to move downward. During the downward movement of the No. 1 inclined plane block 44, it will contact the installation shaft 3, so that the inclined surface of the No. 1 inclined plane block 44 is subjected to the reverse thrust of the installation shaft 3 and moves in the direction away from the installation shaft 3, so that the No. 1 inclined plane block 44 drives the three limit pins 43 to move in the direction away from the installation shaft 3 through the installation plate 42. When the gymnasium is in place, due to the elastic force of the rebounder 41, the installation plate 42 pushes the two No. 1 inclined plane blocks 44 and the three limit pins 43 into the two square holes and the three round holes respectively, so that the three limit pins 43 have a limiting effect on the installation shaft 3 and the connecting shaft 2.Two springs 48 are installed on the inner wall of the connecting shaft 2, and the two springs 48 are respectively connected to two No. 2 inclined plane blocks 46, and the two No. 2 inclined plane blocks 46 are respectively connected to two buttons 45. Two abutment rods 47 are installed on the mounting plate 42, and the two abutment rods 47 are respectively located on the movement tracks of the two No. 2 inclined plane blocks 46. The two buttons 45 are slidably connected to the outer wall of the connecting shaft 2, and the two No. 1 inclined plane blocks 44 and the three limit pins 43 are all slidably connected to the connecting shaft 2. When the staff presses the two buttons 45 on one of the connecting shafts 2, the two buttons 45 move closer to each other. The two buttons 45 respectively drive the two No. 2 inclined plane blocks 46 to move toward the rebounder 41, the No. 2 inclined plane block 46 drives the abutment rod 47 to move away from the mounting shaft 3, the two abutment rods 47 drive the mounting plate 42 to move away from the mounting shaft 3, the mounting plate 42 drives the three limit pins 43 and the two No. 1 inclined plane blocks 44 to move away from the mounting shaft 3, so that the three limit pins 43 lose their limiting effect on the mounting shaft 3 and the connecting shaft 2, and the staff presses the other two buttons 45 to remove the gravure roller 1.

[0030] Through the setting of the gravure roller 1, this embodiment achieves the goal of using one gravure roller 1 to perform coating tests of four different textures or mesh sizes, thereby improving the test efficiency and reducing the material cost of the test process, avoiding the need to frequently replace multiple micro-gravure coating rollers during the coating test stage, which results in low work efficiency and high production costs. Through the setting of the mounting component 4, the staff can quickly disassemble and replace the gravure roller 1, thereby improving work efficiency, and the two mounting shafts 3 can be used for multiple gravure rollers 1, further saving costs.

[0031] When the micro-concave coating roller of the utility model is used, after the gravure roller 1 is installed, the coating test operation can be carried out. When the gravure roller 1 is rotated, the pyramid-shaped texture 11, the quadrilateral texture 12, the oblique line texture 13, and the hexagonal texture 14 are driven to rotate, so that the pyramid-shaped texture 11, the quadrilateral texture 12, the oblique line texture 13, and the hexagonal texture 14 respectively apply the corresponding textures to the material. When the coating test operation is completed, the staff observes the coating effect and compares the pyramid-shaped texture 11, the quadrilateral texture 12, the oblique line texture 13, and the hexagonal texture 14. The coating effect produced by the oblique lines 13 and the hexagonal lines 14 can be compared with the coating effects of several different gravure rollers 1 to select the best coating performance, so as to select the micro-concave coating roller with the corresponding pattern for subsequent coating operation. Through the setting of the gravure roller 1, one gravure roller 1 can be used for coating tests with four different patterns or mesh sizes, which improves the test efficiency and reduces the material cost of the test process, avoiding the need to frequently replace multiple micro-concave coating rollers during the coating test stage, resulting in low work efficiency and high production cost.

[0032] When it is necessary to remove the gravure roller 1, the staff presses the two buttons 45 on one of the connecting shafts 2, and the two buttons 45 move in the direction close to the rebounder 41 respectively, and the two buttons 45 drive the two No. 2 inclined plane blocks 46 to move in the direction close to the rebounder 41 respectively. The two No. 2 inclined plane blocks 46 will contact the two resistance rods 47 respectively during the movement. When the No. 2 inclined plane blocks 46 contact the resistance rods 47, the No. 2 inclined plane blocks 46 will apply a reverse thrust to the resistance rods 47 through the inclined surfaces of their surfaces, so that the No. 2 inclined plane blocks 46 drive the resistance rods 47 to move in the direction away from the installation shaft 3, and the two resistance rods 47 drive The mounting plate 42 moves in the direction away from the mounting shaft 3, and the mounting plate 42 drives the three limit pins 43 and the two No. 1 inclined blocks 44 to move in the direction away from the mounting shaft 3, so that the three limit pins 43 lose their limiting effect on the mounting shaft 3 and the connecting shaft 2. At this time, the two buttons 45 on the other connecting shaft 2 are pressed again, and the two mounting shafts 3 lose connection with the two connecting shafts 2, and the staff can remove the gravure roller 1. When the staff does not press the button 45, the button 45 is reset by the elastic force of the spring 48. When the gravure roller 1 needs to be installed, the two connecting shafts 2 of the gravure roller 1 are aligned with the two mounting shafts 3, and the gravure roller is pressed downward. 1, the gravure roller 1 drives the two connecting shafts 2 to move downward, the connecting shaft 2 drives the mounting plate 42 to move downward through the rebounder 41, the mounting plate 42 drives the two No. 1 inclined plane blocks 44 and the three limit pins 43 to move downward, and the No. 1 inclined plane block 44 will contact the mounting shaft 3 during the downward movement, so that the inclined surface of the No. 1 inclined plane block 44 is subjected to the reverse thrust of the mounting shaft 3 and moves in the direction away from the mounting shaft 3, so that the two No. 1 inclined plane blocks 44 drive the mounting plate 42 to move in the direction away from the mounting shaft 3, and the mounting plate 42 drives the three limit pins 43 to move in the direction away from the mounting shaft 3. Since the side length of the No. 1 inclined plane block 44 is greater than the mounting shaft 3, the mounting plate 42 drives the three limit pins 43 to move in the direction away from the mounting shaft 3. The round hole of the shaft 3, so the No. 1 inclined plane block 44 will not slide into the round hole, when the two No. 1 inclined plane blocks 44 move to the two square hole positions respectively, due to the elastic force of the rebounder 41, the mounting plate 42 pushes the two No. 1 inclined plane blocks 44 and the three limit pins 43 into the two square holes and the three round holes respectively, so that the three limit pins 43 have a limiting effect on the mounting shaft 3 and the connecting shaft 2, and the coating operation can be carried out at this time. Through the setting of the mounting assembly 4, the staff can quickly disassemble and replace the gravure roller 1, which improves the work efficiency, and the two mounting shafts 3 can be commonly used for multiple gravure rollers 1, which further saves costs.

Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the embodiments of the present utility model. Therefore, all equivalent technical solutions also belong to the scope of the embodiments of the present utility model.
