[0023] As Figures 1-6 shown, a fully precision double-roller coating machine with deviation rectification includes a film substrate 6, and also includes a base 1 and a mounting bracket 2. The mounting bracket 2 is fixedly connected to the upper end of the base 1. The film substrate 6 passes horizontally between the base 1 and the mounting bracket 2. A spray material mechanism is connected to the mounting bracket 2. The spray material mechanism is used to spray coating on the film substrate 6. A coating mechanism 4 is connected to the mounting bracket 2. The coating mechanism 4 is used to coat the coating evenly on the film substrate 6. A deviation rectifying mechanism 5 is connected to the mounting bracket 2. The deviation rectifying mechanism 5 is used to perform limiting adjustment according to the size of the film substrate 6 to prevent the film substrate 6 from shifting during coating.
[0024] As Figure 3 shown, in order to spray the coating on the film substrate 6, the spray material mechanism includes a spray material tank 3. The spray material tank 3 is symmetrically arranged on both sides of the film substrate 6. The spray material tank 3 is fixedly connected between the mounting brackets 2. The spray material tank 3 is connected to a spray plate 301. The end of the spray plate 301 is set as an inclined surface. A plurality of spray holes 302 are provided on the spray plate 301.
[0025] As Figure 5As shown in the figure, in order to evenly coat the coating on the film substrate 6, the coating mechanism 4 includes a first motor 401, a driving roller 402 and a driven roller 405. The first motor 401 is fixedly connected to the outside of the mounting frame 2. The driving roller 402 and the driven roller 405 are both rotatably arranged between the mounting frames 2. A first connecting shaft 403 is fixedly connected to the driving roller 402. Both ends of the first connecting shaft 403 rotatably pass through the mounting frame 2. One end of the first connecting shaft 403 is fixedly connected to the output end of the first motor 401. The other end of the first connecting shaft 403 is fixedly connected with a first gear 404. A second connecting shaft 406 is fixedly connected to the driven roller 405. Both ends of the second connecting shaft 406 rotatably pass through the mounting frame 2. One end of the second connecting shaft 406 is fixedly connected with a second gear 407. The first gear 404 and the second gear 407 are both rotatably arranged outside the mounting frame 2. The second gear 407 meshes with the first gear 404. A plurality of bearings 201 are fixedly connected to the mounting frame 2. Both ends of the first connecting shaft 403 and the second connecting shaft 406 are rotatably connected to the bearings 201, thereby reducing the frictional resistance of the first connecting shaft 403 and the second connecting shaft 406 when rotating on the mounting frame 2.
[0026] As Figure 5 , 6 shown in the figure, in order to avoid the film substrate 6 shifting during the coating process of the film substrate 6 and affecting the coating quality, the deviation rectifying mechanism 5 includes a second motor 501, a limiting plate 505 and a sliding rod 504. The second motor 501 is fixedly connected to the outside of the mounting frame 2. The output end of the second motor 501 is fixedly connected with a first screw rod 502. The first screw rod 502 rotatably passes through one side of the mounting frame 2. The end of the first screw rod 502 is fixedly connected with a second screw rod 503. The second screw rod 503 is rotatably connected to the other side of the mounting frame 2. The two limiting plates 505 are respectively threadedly connected to the first screw rod 502 and the second screw rod 503. The sliding rod 504 is fixedly connected between the mounting frames 2. The two limiting plates 505 are both slidably connected to the sliding rod 504. Two grooves 507 are provided on one side of the limiting plate 505. The driving roller 402 and the driven roller 405 are respectively slidably and fittingly passed through the two grooves 507. The pitches of the first screw rod 502 and the second screw rod 503 are the same and the threads are opposite, so that the two limiting plates 505 simultaneously limit the two sides of the film substrate 6 inward.
[0027] As Figures 4-6 shown in the figure, in order to improve the stability of the movement of the limiting plate 505, limiting blocks 506 are symmetrically and fixedly connected to both ends of the limiting plate 505. The limiting blocks 506 are T-shaped. A first limiting groove 202 is provided at the lower end of the mounting frame 2. A second limiting groove 101 is provided at the upper end of the base 1. The two limiting blocks 506 are respectively slidably and fittingly connected to the first limiting groove 202 and the second limiting groove 101.
[0028] When the utility model is in use, the film substrate 6 passes through the space between the driving roller 402 and the driven roller 405 in the mounting frame 2. The coating material is sprayed onto the film substrate 6 through the spray holes 302. The output end of the first motor 401 drives the first connecting shaft 403 to rotate, thereby driving the driving roller 402 to rotate. At the same time, the first gear 404 is driven to rotate, which in turn drives the second gear 407 to rotate, and then drives the second connecting shaft 406 to rotate, and further drives the driven roller 405 to rotate. Thus, the driving roller 402 and the driven roller 405 uniformly coat the coating material on the film substrate 6. At the same time, according to the size of the film substrate 6, the output end of the second motor 501 drives the first screw rod 502 and the second screw rod 503 to rotate, respectively driving the limiting plates 505 on the first screw rod 502 and the second screw rod 503 to move inward simultaneously. At the same time, the limiting plates 505 slide and are limited on the slide rods 504, and the symmetrically arranged limiting blocks 506 slide in the first limiting groove 202 and the second limiting groove 101 to improve the stability of the movement of the limiting plates 505. The two limiting plates 505 are respectively attached to both sides of the film substrate 6 to limit the film substrate 6, preventing the film substrate 6 from shifting during coating and affecting the coating quality.
[0029] In summary, in the embodiment of the utility model, after the coating material is sprayed onto the film substrate 6 by the spraying mechanism, the coating mechanism 4 uniformly coats the coating material on the film substrate 6. Through the limiting plates 505 on the first screw rod 502 and the second screw rod 503 in the deviation rectifying mechanism 5, the two limiting plates 505 can be clamped and attached to both sides of the film substrate 6 according to the size of the film substrate 6, thereby preventing the film substrate 6 from shifting during coating and affecting the coating quality of the film substrate 6.

What is shown in the drawings is only one of the implementation manners of the utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative purpose of the utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the utility model.
