[0036] Referring to FIG. Figure 1 As shown in the drawings, the substrate moves along the direction indicated by the hollow arrow in the drawings, the coating machine comprises a coating device 1 and a scraping device 2 arranged in sequence above the substrate and along the moving direction of the substrate, the scraping device 2 is located in front of the coating device 1, the substrate first passes through the coating device 1 for coating, and then passes through the scraping device 2 for scraping.
[0037] The coating device 1 comprises a coating roller 11, the coating roller 11 can move along the vertical direction to approach or move away from the substrate, when the coating roller 11 is lowered and abuts against the substrate, the coating roller 11 can roll under the driving of the substrate to coat the substrate.
[0038] Referring to FIG. Figure 2 As shown in the drawings, the scraping device 2 comprises a fixed rod 21, a swing rod 22, an elastic member 23 and a scraping plate 24, the fixed rod 21 is fixed and immovable, the swing rod 22 is hinged to the fixed rod 21 and can swing up and down along the fixed rod 21, and the scraping plate 24 is fixed to the lower end of the swing rod 22. The swing rod 22 swings upward along the moving direction of the substrate under the driving of the substrate, and can be reset under the pulling of the elastic member 23 to press the scraping plate 24 against the surface of the substrate.
[0039] In this embodiment, the substrate coated by the coating device 1 is scraped by the scraping device 2, thereby improving the uniformity of film formation. The scraping plate 24 of the scraping device 2 can swing due to the swing rod 22, and is in elastic contact with the substrate, thereby meeting the requirement of film scraping while avoiding scratching of the substrate by the scraping plate 24. Meanwhile, the elastic member 23 can pull the swing rod 22 to swing downward by using its own elastic force, so as to make the scraping plate 24 closely adhere to the surface of the substrate, thereby improving the scraping effect. Because the swing rod 22 can drive the scraping plate 24 to swing, the height position of the scraping plate 24 is not fixed, so as to be used for coating of substrates with different thicknesses.
[0040] Referring to FIG. Figure 4 As shown in the drawings, the fixed rod 21 is provided with a hinge groove 211, part of the swing rod 22 is inserted into the hinge groove 211 and connected with the hinge groove 211 through a hinge shaft 25, a limiting part 212 is arranged in the hinge groove 211, and the swing rod 22 can swing to the position abutting against the limiting part 212 under the pulling of the elastic member 23. The limiting part 212 is used for limiting the swing range of the swing rod 22 under the pulling of the elastic member 23, when the swing rod 22 abuts against the limiting part 212, the swing rod 22 is in the vertical state, and at this time, the elastic member 23 is still in the force storage state.
[0041] In one embodiment, the elastic member 23 is a tension spring.
[0042] One end of the tension spring is fixedly connected with the swing rod 22, and the other end is fixedly connected with the fixed rod 21. The tension spring is pre-tightened so that the swing rod 22 and the limiting portion 212 abut against each other, and the swing rod 22 is in a vertical state. The tension spring is horizontally arranged. When the swing rod 22 swings upward under the driving of the base material, the tension spring is continuously stretched, so that the tension spring can provide a force for the swing rod 22 to move toward the base material, and the scraper 24 abuts against the surface of the base material to scrape the material.
[0043] In one embodiment, the elastic member 23 is a torsion spring.
[0044] The fixed rod 21 is fixedly provided with a hinge shaft 25, and the swing rod 22 rotates around the hinge shaft 25. A torsion spring is sleeved on the hinge shaft 25. One end of the torsion spring is fixed with the swing rod 22, and the other end is fixed with the fixed rod 21. When the swing rod 22 swings upward, the torsion spring is charged, and provides a force for the swing rod 22 to swing downward, so that the scraper 24 abuts against the surface of the base material.
[0045] In one embodiment, a plurality of the fixed rod 21, the swing rod 22 and the elastic member 23 are correspondingly arranged, and a plurality of the swing rod 22 are collectively fixed with one scraper 24 at the lower end. At this time, the elastic member 23 provides a swing reset force for the corresponding swing rod 22, but applies the force to the scraper 24 to make the scraper 24 abut against the surface of the base material.
[0046] For example, referring to FIG. 1, Figure 3 As shown in FIG. 1, two fixed rods 21, two swing rods 22 and two elastic members 23 are arranged. The fixed rod 21 is fixed on the stand 3, and the stand 3 is kept different.
[0047] For example, referring to FIG. 1, Figure 1 As shown in FIG. 1, the paint device 1 and the scraping device 2 are collectively provided with a recovery tank 4 below, and the recovery tank 4 is fixed with the stand 3. The recovery tank 4 is located below the base material. When there is excess paint on the base material, the paint can fall into the recovery tank 4.
[0048] For example, referring to FIG. 1, Figure 1 As shown in FIG. 1, the paint device 1 further comprises a paint tank 12 which synchronously rises and falls with the paint roller 11, and the paint tank 12 provides paint for the paint roller 11.
[0049] In one embodiment, the paint roller 11 is provided with a paint channel, and the surface of the paint roller 11 is provided with a discharge port communicated with the paint channel. The paint tank 12 is communicated with the paint channel through a pipeline, and the pipeline is rotationally connected with the paint roller 11. At this time, the paint stored in the paint tank 12 can enter the paint channel in the paint roller 11 through the pipeline, and then be discharged from the discharge port to be coated on the surface of the base material.
[0050] In one embodiment, part of the paint roller 11 enters the paint box 12, and the paint roller 11 can take out the paint in the paint box 12 when rotating. An opening is formed on the side of the paint box 12, and the paint roller 11 is rotatably connected to the opening. A sealing structure is arranged at the opening to prevent the paint in the paint box 12 from leaking.
[0051] The paint device 1 further comprises a first lifting driving member 13. The paint box 12 is fixedly connected to the first lifting driving member 13 and is lifted under the driving of the first lifting driving member 13. The first lifting driving member 13 drives the paint roller 11 to lift or lower through the paint box 12, so that the paint roller 11 approaches or moves away from the base material. The first lifting driving member 13 is fixed to the stand 3.
[0052] Referring to FIG. 1, Figure 5 As shown in the drawings, the film coating machine further comprises a pressing device 5 located in front of the scraping device 2 along the moving direction of the base material. The pressing device 5 comprises two pressing rollers 51 arranged in an upper and lower spaced manner. The base material passes between the two pressing rollers 51 to press the base material. The distance between the two pressing rollers 51 is adjustable, so that the pressing device 5 can be used for coating films on base materials of different thicknesses.
[0053] The lower pressing roller 51 rotates along its axis under the driving of a rotating driving member 52. The lower pressing roller 51 acts as a power member and can drive the base material to move. The upper pressing roller 51 moves up and down under the driving of a second lifting driving member 53.
[0054] The first lifting driving member 13 and the second lifting driving member 53 are linear modules, which can be a cylinder or a screw nut structure, as long as they can realize linear movement in the upward and downward directions.
[0055] In the working process of the film coating machine in this embodiment, a power member (not shown in the drawings) drives the base material to move along the arrow shown in the drawings. The first lifting driving member 13 drives the paint box 12 and the paint roller 11 to move downward synchronously until the paint roller 11 abuts against the base material. At this time, the paint roller 11 can coat the base material. The coated base material passes through the scraping device 2. The scraping plate 24 elastically contacts the base material. The base material can be pushed by the scraping plate 24 to swing the swing rod 22 upward during the movement process. However, under the elastic action, the scraping plate 24 abuts against the base material to scrape the paint. The scraped base material enters the pressing device 5 to be flattened.
