DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0023] like Figures 1 to 6 As shown, in this embodiment, a coating mechanism with uniform feeding includes a mounting frame 1, a feeding roller 2, a coating steel roller 3, a comma scraper 4, a feeding head 5 and a material accumulation chamber 6, the feeding roller 2 is rotatably connected to the lower end of the mounting frame 1, the comma scraper 4 is located at the upper end of the mounting frame 1, the coating steel roller 3 is between the comma scraper 4 and the feeding roller 2, a material accumulation inclined plate 7 is provided at the lower end of the material accumulation chamber 6, a material passing port 8 is formed between the material accumulation inclined plate 7 and the coating steel roller 3, a feed port 9 is provided at the rear end of the material accumulation chamber 6, the outlet of the feeding head 5 is located on the feed port 9, and the feed port 9 is in a strip shape.

[0024] The substrate 23 moves upward from the bottom, moves upward under the action of the feeding roller 2 and the coating steel roller 3, passes through the feeding port 8 between the material accumulation chamber 6 and the coating steel roller 3, and then passes upward between the comma scraper 4 and the coating steel roller 3 to scrape the layer, and finally moves out. During this period, the feeding head 5 continuously feeds the slurry 24 to the material accumulation chamber 6. When the feeding head 5 is feeding, since the feeding port 9 formed by the material accumulation inclined plate 7 is in a strip shape, the input of the slurry 24 is also uniformly input from the strip-shaped feeding port 9, and the accumulation of the material input from a single port will not be concentrated. It is transported downward from the material accumulation inclined plate 7 to the feeding port 8 of the material accumulation chamber 6, so that it is evenly coated on the substrate 23, and the layer is scraped under the action of the gap between the upper comma scraper 4 and the coating steel roller 3, thereby ensuring the thickness and quality of the coating.

[0025] A feeding cylinder 10 is fixed to the lower ends of both sides of the mounting frame 1, and a driving end of the feeding cylinder 10 is connected to a feeding plate 11 in an inclined manner upward, and the end of the feeding roller 2 is rotatably connected to the feeding plate 11. The feeding cylinder 10 controls the position of the feeding plate 11 through the driving end, thereby controlling the distance between the feeding roller 2 and the coating steel roller 3, and applying substrates 23 of different thicknesses.

[0026] Scraper moving slide rails 12 are arranged on the upper ends of both sides of the mounting frame 1, and scraper seats 13 are connected to the ends of the comma scraper 4. The scraper seats 13 slide on the scraper moving slide rails 12. Moreover, scraper adjustment slide rails 14 are arranged on the upper ends of both sides of the mounting frame 1, and scraper nut seats 15 are in contact with the scraper seats 13. The scraper nut seats 15 slide on the scraper adjustment slide rails 14. The scraper nut seats 15 are threadedly connected with scraper adjustment screws 16. The rotation of the scraper adjustment screws 16 is manually adjusted to control the forward and backward movement of the scraper nut seats 15. The position of the scraper seats 13 is changed by the upper end of the scraper nut seats 15, and the movement of the comma scraper 4 is accurately controlled under the guidance of the scraper adjustment slide rails 14 to meet the distance between the scraper seats 13 and the coating steel roller 3, so as to achieve the adjustment of different coating thicknesses.

[0027] A feeding slide 17 is arranged in the middle part of the mounting frame 1 along the horizontal direction, and a feeding slide 18 is slidably connected to the feeding slide 17. The feeding head 5 and the material accumulation chamber 6 are both installed on the feeding slide 18. A feeding cylinder 19 is fixed on the mounting frame 1, and the driving end of the feeding cylinder 19 is connected to the feeding slide 18. The lower end of the material accumulation inclined plate 7 is connected to the material accumulation slide 20, and the material accumulation slide 20 slides on the feeding slide 18. A material accumulation hand wheel 21 is rotatably connected to the feeding slide 18, and a material accumulation rotating shaft 22 is connected between the material accumulation hand wheel and the material accumulation slide 20, and the material accumulation rotating shaft 22 is threadedly connected to the feeding slide 18.

[0028] When controlling the distance between the material accumulation chamber 6 and the coating steel roller 3, the forward and backward movement of the feeding slide 18 is controlled by the feeding cylinder 19, so that the front and rear position of the material accumulation chamber 6 is changed. At the same time, in order to meet the feeding needs, the distance between the material accumulation chamber 6 and the feeding head 5 is changed, and the material accumulation hand wheel 21 is manually turned. The material accumulation slide 20 is moved by rotating the material accumulation shaft 22, which causes the spacing of the feeding head 5 on the feeding slide 18 to change.

[0029] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
