All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] An efficient coater, comprising a bottom plate 1, a unwinding roller 2 fixedly connected to the surface of the bottom plate 1, a winding roller 3 fixedly connected to the surface of the bottom plate 1, a protective shell 4 fixedly connected to the surface of the bottom plate 1, a dust removal structure 5 arranged on the surface of the protective shell 4, the dust removal structure 5 includes a fixed column 51, a small motor 52 fixedly connected to the surface of the fixed column 51, a fan 53 fixedly connected to the output end of the small motor 52, a dust-proof net 54 fixedly connected to the surface of the protective shell 4, a pressing structure 6 arranged on the surface of the bottom plate 1, the pressing structure 6 includes a fixed shaft 61, a slider 62 slidably connected to the surface of the fixed shaft 6Y, a first spring 63 fixedly connected to the surface of the slider 62, a support frame 64 fixedly connected to the surface of the slider 62, a handle 65 fixedly connected to the side of the support frame 64, an auxiliary roller 66 rotatably connected to the surface of the support frame 64, a roller shaft 7 fixedly connected to the inner wall of the protective shell 4, a flattening structure 8 fixedly connected to the surface of the roller shaft 7, the flattening structure 8 includes a column 81, a fixed rod 82 fixedly connected to the top of the column 81, a sliding rod 83 rotatably connected to the surface of the fixed rod 82, a scraper 84 fixedly connected to the bottom of the sliding rod 83, a second spring 85 fixedly connected to the surface of the sliding rod 83, a top plate 86 fixedly connected to the top of the fixed rod B2, a coating roller 9 rotatably connected to the surface of the roller shaft 7, a material box 10 fixedly connected to the top of the protective shell 4, a conveying pipe 11 fixedly connected to the inner wall of the protective shell 4, a nozzle 12 fixedly connected to the surface of the conveying pipe 11. The pressing structure 6 and the flattening structure 8 are provided. The slider 62 can slide on the surface of the fixed shaft 61, and the first spring 63 applies pressure to the slider 62, so that the auxiliary roller 66 is always in contact with the surface of the coating roller 9 without external force. By pulling the slider 62 through the handle 65, the first spring 63 is compressed, and the substrate is placed in a U-shape between the two auxiliary rollers 66 and the coating roller 9. Release the handle 65, and the first spring 63 presses the auxiliary roller 66 against the coating roller 9, pressing the substrate tightly against the surface of the coating roller 9. After the substrate is coated, the surface is scraped evenly by the scraper 84. The scraper 84 can slide on the fixed rod 82 along with the sliding rod 83, and the scraper 84 is pressed against the surface of the substrate by the second spring 85, so that the coater can adapt to substrates of different thicknesses and is more convenient to use. The dust removal structure 5 is provided. The two fans 53 are driven to rotate by the small motor 52. The two fans 53 rotate in the same direction. One fan 53 blows the dust on the surface of the substrate away, and the other sucks the dust out. Dust-proof nets 54 are arranged on the outer sides of the two fans 53 to prevent the wind blowing into the protective shell 4 from carrying dust to contaminate the substrate, and also prevent dust from adhering to the fans 53, increasing the service life of the fans 53 and avoiding the problem that the finished product quality is poor due to dust adhering to the substrate.

[0024] Further, two sets of first square grooves are formed on the surface of the protective shell 4, and the fixing columns 51 are fixedly connected to the inner walls of the first square grooves. The two sets of first square grooves face the pressing structure 6, and the rotation directions of the two sets of fans 53 are the same. When the pressing structure 6 presses the base material against the coating roller 9, the dust on the surface of the base material is removed through the cooperation of the two sets of fans 53.

[0025] Further, four sets of second square grooves are formed on the surface of the bottom plate 1, and there are two sets of fixed shafts 61. The two ends of one set of fixed shafts 61 are respectively fixedly connected to the inner walls of the two sets of second square grooves, and there are four sets of sliders 62. The four sets of sliders 62 are respectively slidably connected in the four sets of second square grooves.

[0026] Further, there are four sets of first springs 63. One end of each first spring 63 is fixedly connected to the inner wall of the second square groove, and the other end of the first spring 63 is fixedly connected to the slider 62. The slider 62 is extruded into the second square groove away from the first spring 63 by the elastic force of the first spring 63.

[0027] Further, circular grooves are formed at both ends of the sliding rod 83. The sliding rod 83 is sleeved on the surface of the fixed rod 82, and the bottom of the scraper 84 is in contact with the surface of the coating roller 9. After the coating of the base material is completed, the scraper 84 levels its surface.

[0028] Further, one end of the second spring 85 is fixedly connected to the sliding rod 83, and the other end of the second spring 85 is fixedly connected to the top plate 86. The scraper 84 is pressed against the surface of the base material by the elastic force of the second spring 85.

[0029] Further, the top of the conveying pipe 11 penetrates through the protective shell 4 and is fixedly connected to the material box 10. The nozzle 12 is inclined, and the base material is preliminarily sprayed through the nozzle 12.

[0030] Working principle: The winding roller 3 completes winding through the motor, and connects the base material on the unwinding roller 2 with the winding roller 3. When connecting the base material, the slider 62 is pulled outwards through the handle 65. At this time, the first spring 63 is compressed. The base material is passed under one set of auxiliary rollers 66, then above the coating roller 9, and finally under the other set of auxiliary rollers 66 and connected to the winding roller 3, so that the base material is placed in a U-shape between the two sets of auxiliary rollers 66 and the coating roller 9. The handle 65 is released, and the first spring 63 presses the auxiliary roller 66 against the coating roller 9, pressing the base material against the surface of the coating roller 9. Before coating, the two sets of fans 53 are driven to rotate by the small motor 52. One set of fans 53 blows the dust on the surface of the base material away, and the other set sucks the dust out. After the dust on the surface of the base material is blown away, the coating is sprayed onto the surface of the base material through the nozzle 12. At this time, the coating is unevenly distributed on the surface of the base material. The surface is leveled by the scraper 84. The scraper 84 can slide on the fixed rod 82 along with the sliding rod 83, and the scraper 84 is pressed against the surface of the base material by the second spring 85.

[0031] It will be apparent to those skilled in the art that the present utility model is not limited to the details of the above-described exemplary embodiments, and that the present utility model can be implemented in other specific forms without departing from the spirit or essential characteristics thereof. Therefore, in any regard, the embodiments should be regarded as exemplary and non-restrictive.

Accordingly, all changes that fall within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
