[0030] Reference Figures 1 to 7 The utility model provides a closed material box, specifically, the closed material box includes a material box body 10, a moving assembly and a rotating assembly, the material box body 10 is arranged on the moving assembly, and the moving assembly is used to control the material box body 10 to move in the horizontal direction. The rotating assembly includes an adjusting member 154, the adjusting member 154 is in contact with the end of the material box body 10, and when the adjusting member 154 is controlled to move toward the direction of the material box body 10, the adjusting member 154 can drive the material box body 10 to rotate.
[0031] Reference Figures 1 to 4 In this embodiment, the material box body 10 has a slurry chamber, and the inner peripheral contour of the slurry chamber is adapted to the outer peripheral contour of the gravure roller 2 of the base coater. When the material box body 10 is installed on the coating mechanism of the base coater, the slurry chamber of the material box body 10 can be enclosed with the gravure roller 2 to form a closed chamber for the slurry, which plays a role in preventing the slurry from splashing. A material receiving box 13 is provided at the bottom of the closed chamber. After the closed material box replaces consumables such as a scraper, when the closed material box is close to the gravure roller again, the parallelism and inclination of the closed material box need to be re-fine-tuned. During the adjustment process, the slurry will flow out from the gap between the scraper and the gravure roller. The material receiving box 13 can catch the flowing slurry. After the closed material box is fine-tuned, it will not leak during normal use.
[0032] Reference Figures 1 to 3 The material box body 10 is provided with a scraper assembly, which is arranged in the slurry chamber, and the scraper assembly is in contact with the roller surface of the gravure roller 2. Specifically, the scraper assembly includes an upper scraper 181 and a lower scraper 182, the lower scraper 182 is arranged at the bottom of the slurry chamber, and the upper scraper 181 is arranged at the top of the slurry chamber. It can be understood that when the gravure roller 2 of the bottom coating machine rotates counterclockwise, the upper scraper 181 can scrape off the excess slurry on the roller surface of the gravure roller 2; when the gravure roller 2 of the bottom coating machine rotates clockwise, the lower scraper 182 can scrape off the excess slurry on the roller surface of the gravure roller 2.
[0033] Reference Figures 1 to 3The utility model provides a slurry reflux structure for processing the scraped excess slurry. Specifically, the material box body 10 is provided with a plurality of feed ports 12 and a discharge port 11 connected to the slurry chamber, a feed channel 120 is provided between the feed port 12 and the slurry chamber, a discharge channel 111 is provided between the discharge port 11 and the slurry chamber, a flow channel is formed between the gravure roller 2 and the back plate of the material box body 10, and an upper scraper and a lower scraper are provided at the connection between the flow channel and the discharge port 11 and the feed port 12. The slurry enters from the lower feed port 12, flows into the feed channel 120, and then flows into the flow channel through the obstruction of the lower scraper, and then flows into the discharge channel 111 through the obstruction of the upper scraper, and finally flows out from the discharge port 11. At the same time, sponge baffles are provided at both ends of the flow channel to ensure that the slurry does not flow out from the end surface.
[0034] The feed port 12 and the discharge port 11 are evenly distributed on the material box body 10. During the coating process, the slurry provided by the coating mechanism flows into the slurry chamber through the feed port 12 and the feed channel 120, and the excess slurry flows back to the feeding device of the coating mechanism from the discharge channel 111 and the discharge port 11. In order to facilitate the slurry reflux, the plurality of discharge ports 11 are connected by a connecting pipe 110. By providing the slurry reflux structure, the precipitation degree of the slurry can be reduced, the mixing uniformity of the slurry can be improved, and the coating quality can be ensured.
[0035] Reference Figure 1 , Figures 4 to 7 The material box body 10 is connected to a fixed beam 14 , and mounting boxes 15 are provided at both ends of the fixed beam 14 . A rotating shaft 150 is provided inside the mounting box 15 , and the end of the fixed beam 14 is sleeved on the outer periphery of the rotating shaft 150 .
[0036] The moving assembly includes a driving device 170 and a moving plate 171 connected to the output end of the driving device 170, and the moving plate 171 is connected to the installation box 15. In this embodiment, the driving device 170 includes a cylinder, and the movement of the moving plate 171 in the horizontal direction is achieved by controlling the extension and contraction of the cylinder, thereby driving the installation box 15 and the fixed beam 14 to move in the horizontal direction.
[0037] The closed material box also includes a positioning plate 16, on which a slide rail assembly is provided, and the installation box 15 is connected to a slider 160 in the slide rail assembly, and the slide rail assembly provides a guide for the movement of the installation box 15 and the material box body 10. The positioning plate 16 is also provided with a displacement detection device 161, and the displacement detection device 161 can detect the movement distance of the installation box 15. In this embodiment, the displacement detection component adopts a displacement dial gauge, and when the installation box 15 moves, the movement distance of the material box body 10 can be obtained by reading the indication of the displacement dial gauge.
[0038] In this embodiment, the mounting box 15 is provided with an adjusting screw 152 and a locking handle 153. The adjusting direction of the adjusting screw 152 is parallel to the moving direction of the moving assembly. When the adjusting screw 152 is adjusted to a preset position, the locking handle 153 locks the adjusting screw 152. It can be understood that the preset position refers to the position where the material box body 10 and the gravure roller 2 enclose a closed chamber for the slurry.
[0039] A follower plate 1501 is also provided on the periphery of the rotating shaft 150, the adjusting member 154 is in contact with the follower plate 1501, a detection block is provided on the side end of the follower plate 1501, and an angle detection device 155 is provided on the moving plate 171, and the angle detection device 155 is in contact with the detection block. In this embodiment, the angle detection device 155 adopts an inclination direction dial indicator. When the control adjusting member 154 moves toward the direction of the material box body 10, the follower plate 1501 will rotate under the action of the abutting force, and the detection block provided on the follower plate 1501 will also rotate accordingly. The angle detection device 155 can detect the rotation angle of the detection block, and then the rotation angle of the material box body 10 can be obtained by reading the indication of the inclination direction dial indicator.
[0040] In this embodiment, a positioning pin 156 is provided on the installation box 15 . When the follower plate 1501 rotates to a preset angle, the positioning pin 156 is adjusted to abut against the follower plate 1501 , thereby limiting the positioning of the follower plate 1501 .
[0041] The working contents of the closed material box are as follows:
[0042] Under normal coating conditions, the material box body 10 and the gravure roller 2 are combined to form a closed chamber for the slurry. The slurry provided by the coating mechanism flows into the slurry chamber from the feed port 12 to coat the gravure roller 2. The excess slurry on the surface of the gravure roller 2 is scraped off by the scraper assembly and flows back to the feeding device of the coating mechanism through the discharge port 11.
[0043] When the operator needs to replace the scraper or clean the slurry chamber of the material box, the position of the material box body 10 needs to be adjusted, and the adjustment steps are as follows: control the material box body 10 to move to a preset distance in the direction away from the gravure roller 2 through the moving component; drive the material box body 10 to rotate to a preset angle through the rotating component; adjust the positioning pin 156 to limit the position of the follower plate 1501 so that the material box body 10 can no longer rotate; the operator replaces the scraper or cleans the slurry chamber; after the operation is completed, the rotating component drives the material box assembly to rotate and reset, and the moving component drives the material box body 10 to move to the closed chamber enclosed with the gravure roller 2 to form the slurry.
