DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, a coating device for melamine film paper includes a conveying mechanism 1, a coating mechanism 2 is fixedly installed in the middle of the conveying mechanism 1, a scraping mechanism 3 is fixedly installed on the upper end of the coating mechanism 2, the scraping mechanism 3 includes a collecting bin 2 31, scrapers 32 are fixedly connected to both sides of the inner middle part of the collecting bin 2 31, reciprocating screws 34 are rotatably connected to both sides of the inner middle and lower parts of the collecting bin 2 31, a motor 33 is fixedly connected to the rear end of the right reciprocating screw 34, a movable block 35 is threadedly connected to the middle outer periphery of the reciprocating screw 34, and a gear 2 36 is fixedly connected to the front end of the reciprocating screw 34.

[0021] In this embodiment, the upper ends of the movable blocks 35 are slidably connected to the lower ends of the scrapers 32, and the gears 36 on both sides are meshed with each other. The conveying mechanism 1 includes a movable base 11, and the upper end of the movable base 11 is arranged with an input roller 12, a pressure roller 13, a tensioning roller 14 and an output roller 15 from left to right. The inner upper sides of the tensioning roller 14 are rotatably connected with drying rollers 16, and the front and rear ends of the collecting bin 2 31 are fixedly connected to the middle and upper parts of the inner front and rear sides of the tensioning roller 14, and the front end of the motor 33 is fixedly connected to the middle and upper part of the rear side of the tensioning roller 14.

[0022] Specifically, after the waterproof paint-coated part of the melamine-filmed paper is transported to the interior of the second collecting bin 31, the scraper 32 scrapes off the excess paint on the melamine-filmed paper to ensure that the melamine-filmed paper is evenly coated. At the same time, the motor 33 drives the reciprocating screw 34 on the right to rotate, and drives the reciprocating screw 34 on the left to rotate through the gear 2 36, thereby driving the movable blocks 35 on both sides to move back and forth, and scrapes off the excess paint at the lower end of the scraper 32, so as to facilitate the subsequent scraping off of the excess paint on the melamine-filmed paper. By arranging the scraping mechanism 3 at the upper end of the coating mechanism 2, it is possible to scrape off the excess paint on the melamine-filmed paper while applying paint to both sides of the melamine-filmed paper, so that the paint coating on both sides of the melamine-filmed paper is more even.

[0023] In this embodiment, the coating mechanism 2 includes a collecting bin 21, and coating rollers 22 are rotatably connected to both sides of the inner middle part of the collecting bin 21, and the front end of the coating roller 22 is fixedly connected to a gear 23, and the outer periphery of the front end of the left coating roller 22 is fixedly connected to a pulley 24, and the pulley 24 is connected to the pulley 26 through a transmission belt 25.

[0024] Specifically, the melamine-coated paper is sequentially passed through the upper end of the input roller 12, the lower end of the pressure roller 13, between the coating rollers 22, between the drying rollers 16, the upper end of the tensioning roller 14 and the lower end of the output roller 15, and the input roller 12, the pressure roller 13, the tensioning roller 14, the output roller 15, the coating roller 22 and the motor 33 are started to convey the melamine-coated paper to the right while coating the surface of the melamine-coated paper with waterproof paint.

[0025] Working principle:

[0026] First, the melamine film paper is passed through the upper end of the input roller 12, the lower end of the pressure roller 13, between the coating rollers 22, between the drying rollers 16, the upper end of the tension roller 14 and the lower end of the output roller 15 in sequence, and the input roller 12, the pressure roller 13, the tension roller 14, the output roller 15, the coating roller 22 and the motor 33 are started, and the melamine film paper is conveyed to the right while the surface of the melamine film paper is coated with waterproof paint. At the same time, when the melamine film paper coated with waterproof paint is conveyed to the inside of the collecting bin 2 31, the scraper 32 removes the excess paint on the melamine film paper. Scrape off to make the melamine film paper evenly coated. At the same time, the motor 33 drives the reciprocating screw 34 on the right to rotate, and drives the reciprocating screw 34 on the left to rotate through the gear 2 36, thereby driving the movable blocks 35 on both sides to move forward and backward, and scrapes off the excess paint at the lower end of the scraper 32, so as to facilitate the subsequent scraping off of the excess paint on the melamine film paper. By arranging the scraping mechanism 3 at the upper end of the coating mechanism 2, it is possible to scrape off the excess paint of the melamine film paper while applying paint to both sides of the melamine film paper, so that the paint coating on both sides of the melamine film paper is more even.
