Technical Field

[0001] The utility model relates to the technical field of coating rollers, in particular to a coating roller structure for release paper coating. Background Technique

[0002] With the rapid development of electronic digital products and the automotive industry, protective films have also developed rapidly, such as release films, anti-static films, and so on. The production process of the protective film is generally as follows: the film is unrolled on the unwinding mechanism, then a functional coating is applied to the film by a coater, then the functional coating is cured through a curing chamber, and finally it is wound up on the winding mechanism, and a protective layer is attached while winding up.

[0003] After retrieval, the utility model with the Chinese patent publication number CN219483190U discloses an adjustable coating roller mechanism, which includes a frame and a coating roller mechanism arranged on the frame. The coating roller mechanism includes a traction member and a glue coating member. The glue coating member includes a rubber roller, a lifting assembly, and a fine-tuning assembly. The rubber roller is rotatably arranged on the lifting assembly, and the fine-tuning assembly is fixed between the traction member and the rubber roller, and includes a fine-tuning drive assembly, a bearing block, and a sliding jacking block.

[0004] Generally, the above-mentioned coating roller has an all-open structure. When the width of the coating roller is greater than that of the substrate, the liquid outlet holes at both ends will continuously overflow outward, resulting in waste of the coating material, and there is room for improvement. Content of the Utility Model

The filling component includes the same bidirectional lead screw rotatably connected to the inner walls on both sides of the bottom plate. Threaded sleeves are sleeved on the threads at both ends of the bidirectional lead screw, and an installation frame one is slidably inserted into the two installation frames one. The two limit rods are respectively fixedly connected to the inner walls on both sides of the bottom plate. A filling column is rotatably connected to the top of each of the two installation frames one. A motor two is fixedly installed on the outer wall of one side of the bottom plate, and the rotating shaft of the motor two is coaxially fixed to one end of the bidirectional lead screw.

[0007] As a further preference of this technical solution, a through hole is opened in the middle of one of the filling columns, and a liquid inlet pipe is fixedly installed on the outer wall of one side of the top of the bottom plate. The liquid inlet pipe is slidably inserted into the through hole of the filling column.

[0008] It can block the small holes at both ends of the roller body according to the width of the release paper, thus avoiding the problem that the small holes that cannot reach the release paper substrate also discharge the same material. Adjust the liquid discharge range of the coating roller according to the width of the release paper substrate. Start the second motor on one side of the bottom plate. The rotating shaft of the second motor drives the bidirectional lead screw to rotate. The two mounting brackets I restricted by the limiting rod will be driven by the bidirectional lead screw to move towards each other. The filling columns rotating inside the mounting bracket I can block the small holes at both ends, effectively avoiding waste of coating materials. The liquid inlet pipe is slidably inserted into the through hole of the filling column, which can ensure the normal rotation of the filling column while also enabling normal liquid discharge.

[0009] As a further preference of this technical solution, a fixing component is installed on the top of the bottom plate, and the fixing component is located on one side of the filling component.

[0010] As a further preference of this technical solution, the fixing component includes two limiting grooves opened on the inner wall of the bottom of the bottom plate. A mounting bracket II is slidably connected to each of the two limiting grooves. A bolt is threadedly connected to the extending end of each of the two mounting brackets II. The two bolts can respectively contact the bottom walls of the two limiting grooves. A connecting ring is rotatably connected to each of the two mounting brackets II. Protrusions are provided on the circumferential inner walls of the two connecting rings.

A card slot adapted to the protrusion is opened on the circumferential outer wall of the roller body. The two filling columns can just be slidably inserted into the circumferential inner wall of the roller body.

[0012] If the roller body needs to be disassembled, just rotate the bolt first so that it no longer contacts the limiting groove. At this time, the restriction of the mounting bracket II will also be lost. Then move the mounting bracket II along the limiting groove. The roller body is no longer restricted. Then drive the filling column to disengage from the roller body, and it can be easily removed.

[0013] As a further preference of this technical solution, a toothed ring is fixedly sleeved on one side of the circumferential outer wall of the roller body. A motor I is fixedly installed on the outer wall of one side of the mounting bracket II. A gear is coaxially fixed to the rotating shaft of the motor I. The gear meshes with the toothed ring.

Two limiting rods 402 are slidably inserted into the two first mounting frames 403. The two limiting rods 402 are respectively fixedly connected to the inner walls on both sides of the bottom plate 1. A filling column 404 is rotatably connected to the top of each of the two first mounting frames 403. A second motor 405 is fixedly installed on the outer wall of one side of the bottom plate 1, and the rotating shaft of the second motor 405 is coaxially fixed to one end of the bidirectional lead screw 401.

[0025] A through hole is formed in the middle of one of the filling columns 404. A liquid inlet pipe 406 is fixedly installed on one side of the outer wall of the top of the bottom plate 1, and the liquid inlet pipe 406 is slidably inserted into the through hole of the filling column 404.

[0026] According to the width of the release paper substrate, the liquid outlet range of the coating roller is adjusted. The second motor 405 on one side of the bottom plate 1 is started. The rotating shaft of the second motor 405 drives the bidirectional lead screw 401 to rotate. The two first mounting frames 403 restricted by the limiting rods 402 will be driven by the bidirectional lead screw 401 to move towards each other. The filling columns 404 rotating inside the first mounting frames 403 can block the small holes at both ends, effectively avoiding waste of the coating material. The liquid inlet pipe 406 is slidably inserted into the through hole of the filling column 404, which can ensure that the filling column 404 can rotate normally and also discharge liquid normally.

[0027] As Figure 2 and Figure 3 shown in the figure, a fixing component 5 is installed on the top of the bottom plate 1, and the fixing component 5 is located on one side of the filling component 4.

[0028] The fixing component 5 includes two limiting grooves 501 formed in the inner wall of the bottom of the bottom plate 1.

The rotating shaft of the second motor 405 drives the bidirectional lead screw 401 to rotate. The two first mounting brackets 403 restricted by the limiting rods 402 will be driven by the bidirectional lead screw 401 to move towards each other. The filling columns 404 rotating inside the first mounting brackets 403 can block the small holes at both ends, effectively avoiding waste of the coating material. The liquid inlet pipe 406 is slidably inserted into the through hole of the filling column 404, which can ensure that the filling column 404 can rotate normally and also discharge liquid normally. Start the first motor 8 outside the second mounting bracket 502. The rotating shaft of the first motor 8 drives the gear 7 to rotate. The gear 7 can drive the roller body 3 to rotate through the toothed ring 6 meshing with it. If it is necessary to disassemble the roller body 3, just rotate the bolt 504 first so that it no longer contacts the limit groove 501. At this time, the restriction of the second mounting bracket 502 will also be lost. Then, move the second mounting bracket 502 along the limit groove 501. The roller body 3 is no longer restricted.
