[0002] In the production and processing of coatings, inks, and other similar industries, roller coating is a commonly used method. Roller coating equipment uses rollers to evenly apply coating to the surface of the object to be coated. However, existing roller coating equipment has several problems in use. Due to the lack of effective thickness control methods, it is difficult to maintain a constant coating thickness. In actual production, the surface flatness of different batches of objects to be coated varies, and the distance between the roller and the object is difficult to adjust precisely, resulting in inconsistent coating thickness and affecting product quality. Furthermore, during the coating process, the object to be coated and the roller cannot always maintain close contact, easily leading to coating accumulation or missed areas. This not only wastes coating but also requires frequent rework, severely impacting production efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a roller coating device with constant coating thickness, including a base 1 and a mounting base 2. The mounting base 2 is fixedly connected to the top of the base 1, and a movable frame 5 is slidably connected to the top of the mounting base 2. The movable frame 5 moves along the top of the mounting base 2. A roller coating roller 8 is slidably connected inside the movable frame 5. The roller coating roller 8 moves within the mounting base 2, and its position is adjusted according to the thickness of the object to maintain a constant coating thickness. A pressure roller 9 is rotatably connected inside the movable frame 5 and located below it. The pressure roller 9 ensures that the object to be coated is in close contact with the roller, guaranteeing uniform coating thickness, improving coating quality and production efficiency. A lead screw 6 is rotatably connected to one side of the mounting base 2. The outer side of the lead screw 6 is threadedly connected to the movable frame 5. The rotation of the lead screw 6 moves the movable frame 5. A first motor 7 is fixedly connected to one side of the mounting base 2. One end of the lead screw 6 is fixedly connected to the output end of the first motor 7. When the first motor 7 is turned on, it rotates the lead screw 6. Support plates 3 are symmetrically fixedly connected to the top of the mounting base 2. Conveying rollers 4 are rotatably connected between the support plates 3 to better transport objects. A connecting frame 20 is slidably connected inside the movable frame 5. The connecting frame 20 moves along the inside of the movable frame 5. The bottom two ends of the connecting frame 20 are rotatably connected to the coating roller 8. The movement of the coating roller 8 moves the connecting frame 20.

[0018] Furthermore, a fixed frame 16 is fixedly connected to one side of the movable frame 5, and one end of the pressure roller 9 passes through one side of the movable frame 5 and is rotatably connected to the fixed frame 16. The pressure roller 9 rotates inside the movable frame 5.

[0019] Furthermore, a second motor 17 is fixedly connected to one side of the fixed frame 16, and one end of the pressure roller 9 passes through one side of the fixed frame 16 and is fixedly connected to the output end of the second motor 17. After the second motor 17 is turned on, it drives the pressure roller 9 to rotate.

[0020] Furthermore, a fourth gear 18 is fixedly connected to the outer side of one end of the pressure roller 9. The rotation of the pressure roller 9 causes the fourth gear 18 to rotate. A third gear 15 is rotatably connected to one side of the moving frame 5. One side of the third gear 15 is meshed with the fourth gear 18. The rotation of the fourth gear 18 causes the third gear 15 to rotate.

[0021] Furthermore, a second adjusting plate 14 is rotatably connected to one side of the third gear 15, and a second gear 13 is rotatably connected to one end of the second adjusting plate 14. The movement of the second gear 13 moves the second adjusting plate 14. The second adjusting plate 14 is positioned such that the second gear 13 moves along the outside of the third gear 15. One side of the second gear 13 meshes with the third gear 15, and the rotation of the third gear 15 causes the second gear 13 to rotate.

[0022] Furthermore, a movable block 10 is slidably connected to one side of the movable frame 5, and one end of the coating roller 8 is fixedly connected to the movable block 10. The movable block 10 moves, causing the coating roller 8 to move as well.

[0023] Furthermore, one end of the coating roller 8 passes through one side of the moving block 10 and is fixedly connected to the first gear 11. The rotation of the first gear 11 causes the coating roller 8 to rotate. One end of the first gear 11 is rotatably connected to the first adjusting plate 12. The movement of the first gear 11 causes the first adjusting plate 12 to move. One end of the first adjusting plate 12 is rotatably connected to the second gear 13, so that the first gear 11 moves along the outside of the second gear 13. One side of the second gear 13 is meshed with the first gear 11. The rotation of the second gear 13 causes the first gear 11 to rotate.

[0024] Furthermore, an electric telescopic rod 19 is fixedly connected to one side of the movable frame 5. The output end of the electric telescopic rod 19 is fixedly connected to the movable block 10. After the electric telescopic rod 19 is opened, it moves the movable block 10 to adjust the position of the coating roller 8.

[0025] In use, when a roller coating operation is required on an object, the object is first placed on the conveyor roller 4 on top of the mounting base 2. The conveyor roller 4 is driven to rotate by an external drive mechanism, such as through belt drive, so as to smoothly transport the object to the coating area. At this time, according to the thickness of the object to be coated, the electric telescopic rod 19 is activated. The output end of the electric telescopic rod 19 pushes the moving block 10 to slide on one side of the moving frame 5. Because one end of the coating roller 8 is fixedly connected to the moving block 10, the coating roller 8 will move with the moving block 10 to precisely adjust the position of the coating roller 8 so that the distance between the coating roller 8 and the surface of the object reaches the set coating thickness. During the movement of the coating roller 8, the first gear 11 at one end of the coating roller 8 also moves. Since the first gear 11 is rotatably connected to the second gear 13 through the first adjusting plate 12, and the second gear 13 meshes with the third gear 15, and the third gear 15 meshes with the fourth gear 18 at one end of the pressure roller 9, the movement of the coating roller 8 will drive a series of gear transmissions to realize the position adjustment of the coating roller 8 and ensure that the coating roller 8 can... The coating roller 8 is tightly attached to the surface of the object to be coated. After the position of the coating roller 8 is adjusted, the first motor 7 is started. The output end of the first motor 7 drives the lead screw 6 to rotate. Since the outer side of the lead screw 6 is threadedly connected to the moving frame 5, the rotation of the lead screw 6 is converted into the linear sliding of the moving frame 5 on the top of the mounting base 2, so that the moving frame 5 moves the coating roller 8 and the pressure roller 9 inside as a whole from left to right. After adjusting the position of the moving frame 5 on the top of the mounting base 2, the second motor 17 is started. The second motor 17 drives the pressure roller 9 to rotate. When the pressure roller 9 rotates, the fourth gear 18 on one side rotates accordingly. Through the meshing transmission with the third gear 15, the second gear 13, and the first gear 11, the coating roller 8 is driven to rotate synchronously. Under the rotation action of the coating roller 8 and the pressure roller 9, the coating is evenly coated on the surface of the object. At the same time, the pressure roller 9 presses the object tightly against the coating roller 8 to ensure that the coating is evenly coated and to avoid accumulation or missed coating. As the conveying roller 4 continues to convey the object, the coating operation can be carried out continuously and efficiently. And no matter how the thickness of the object changes, a constant coating thickness can be maintained through the above-mentioned adjustment mechanism.
