[0003] At present, the paper is passed through a glue tank filled with glue liquid, the glue liquid is allowed to penetrate into the paper, and then the excess glue is squeezed out by two rollers, and then dried in an oven. To control the glue amount and uniformity, the gap control between the two rollers and the manufacturing accuracy and rotation accuracy of the rollers are the key. However, due to the limitation of roller processing accuracy and the influence of roller running jump, it is difficult to achieve the requirement of controlling the uniformity of glue amount, so it is urgent to improve this.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 7 As shown, a mechanism for controlling the amount of glue on the surface of decorative paper comprises a frame 1, wherein a glue groove 12, a pre-scraping mechanism 2 and a scraping mechanism 3 are arranged inside the frame 1, and a conveying roller 11 is arranged inside the glue groove 12. Figure 1 As shown, the paper is transported from right to left, and after being coated with glue by the transport roller 11 in the glue groove 12, it is transported through the pre-scraping mechanism 2 and the scraping mechanism 3.

[0028] like Figure 6As shown, the pre-scraping mechanism 2 includes a first squeezing roller 21 and a second squeezing roller 22, the first squeezing roller 21 and the second squeezing roller 22 are gap-matched, and the paper is transmitted through the gap between the first squeezing roller 21 and the second squeezing roller 22. The first squeezing roller 21 is connected to the first gear 23 on both sides, and the second squeezing roller 22 is connected to the second gear 24 on both sides. The first gear 23 is meshed with the second gear 24. Through the synchronous rotation of the first squeezing roller 21 and the second squeezing roller 22, the glue on the surface of the paper can be pre-scraped flat.

[0029] like Figure 6 and Figure 7 As shown, the second squeezing roller 22 is provided with a second adjustment mechanism 8 on both sides, and the second squeezing roller 22 can be horizontally moved close to or away from the first squeezing roller 21 through the second adjustment mechanism 8. Specifically, the second adjustment mechanism 8 includes a shell 81 fixed to the frame 1 and a handle bolt 82 threadedly connected to the shell 81, and the shell 81 is provided with a first guide groove 83 and a second guide groove 84. The two ends of the second squeezing roller 22 are connected with a first slider 25 through a bearing, and the first slider 25 is inserted into the first guide groove 83. The second guide groove 84 is provided with an inclined block 85. The end of the handle bolt 82 is inserted into the second guide groove 84 and abuts against the lower part of the inclined block 85. The inclined block 85 can push the first slider 25 to move along the first guide groove 83. A cover plate 86 is installed on one side of the first guide groove 83. A spring 87 is installed in the first guide groove 83, and one end of the spring 87 abuts against the cover plate 86 and the other end abuts against the side of the first slider 25.

[0030] like Figure 4 As shown, when the distance between the first squeezing roller 21 and the second squeezing roller 22 needs to be reduced, the handle bolt 82 is turned, and the handle bolt 82 pushes the inclined block 85 to rise, and the first slider 25 is pushed to move to the left side by the inclined block 85. At this time, it is equivalent to the inclined block 85 pushing the second squeezing roller 22 to move toward the first squeezing roller 21, so as to achieve the position adjustment of the first squeezing roller 21 and the second squeezing roller 22, so as to meet the pre-scraping operation of glue on the surface of paper with different thicknesses. Among them, the inclined surface of the contact side of the inclined block 85 and the first slider 25 is very small, so that the moving position of the second squeezing roller 22 is limited, and therefore it will not affect the meshing of the first gear 23 and the second gear 24.

[0031] The scraping mechanism 3 includes a wire rod 4 and a motor 6, and the motor 6 can drive the wire rod 4 to rotate. The driving shaft of the motor 6 is connected to the wire rod 4 through a universal joint 61. The scraping mechanism 3 is located above the pre-scraping mechanism 2. There are two scraping mechanisms 3, and the two scraping mechanisms 3 are distributed up and down respectively. The scraping mechanism 3 located at the bottom is the first scraping mechanism 3a, and the scraping mechanism 3 located at the top is the second scraping mechanism 3b. The first scraping mechanism 3a and the second scraping mechanism 3b have the same shape. The wire rod 4 of the first scraping mechanism 3a and the wire rod 4 of the second scraping mechanism 3b are arranged opposite to each other. The paper is transmitted between the two scraping mechanisms 3, and the wire rods 4 of the two scraping mechanisms 3 are respectively attached to the front and back surfaces of the paper.

[0032] The wire rod 4 is a standard part, and the surface of the wire rod 4 has dense stripes. The wire rod 4 is driven to rotate by the motor 6 to scrape off a portion of the glue on the surface of the paper. By controlling the rotation speed of the wire rod 4, the amount of glue scraped off the paper surface can be controlled. By replacing wire rods 4 of different specifications (the stripes on the surfaces of wire rods 4 of different specifications are different), the amount of glue scraped off the paper surface can also be controlled, thereby controlling the amount of glue on the paper surface and effectively ensuring the uniformity of gluing. The paper is first scraped flat by the pre-scraping mechanism 2, and then scraped by the coating mechanism 3, which can make the glue amount on the paper surface more accurately controlled, which is beneficial to improving the performance of the paper.

[0033] like Figure 4 As shown, the scraping mechanism 3 includes a mounting seat 5, a limiting groove 51 is provided inside the mounting seat 5, the wire rod 4 is inserted into the limiting groove 51, the wire rod 4 can rotate about the axis of the limiting groove 51, the surface of the wire rod 4 protrudes outside the limiting groove 51, the mounting seat 5 is made of plastic material, the wire rod 4 can rotate inside the mounting seat 5, and the wire rod 4 is installed by the mounting seat 5, which can effectively improve the supporting effect of the wire rod 4, which is beneficial to improve the concentricity of the rotation of the wire rod 4, thereby improving the scraping effect of the glue on the paper surface.

[0034] like Figure 2As shown, the first scraping mechanism 3a can be horizontally moved by the first adjusting mechanism 7 to approach or move away from the second scraping mechanism 3b. Specifically, the second scraping mechanism 3b is fixed to the frame 1 through the support plate 13. The first adjusting mechanism 7 includes a base 71, a second slider 72, a cylinder 73 and a slide rail 74. The base 71 is fixed to the mounting base 5 of the first scraping mechanism 3a, the base 71 is fixed to the second slider 72, the cylinder 73 and the slide rail 74 are respectively fixed to the frame 1, and the telescopic rod of the cylinder 73 is fixed to the second slider 72. The cylinder 73 is fixed, and can drive the second slider 72 to move along the slide rail 74. There are two first adjustment mechanisms 7, which are respectively arranged on both sides of the first scraping mechanism 3a. When the first scraping mechanism 3a needs to be moved, the cylinder 73 works and drives the second slider 72 to move. The second slider 72 is guided by the slide rail 74. The second slider 72 drives the base 71 to move, thereby driving the first scraping mechanism 3a fixed on the side of the base 71 to move. By moving the first scraping mechanism 3a, it is convenient for paper to pass through the first scraping mechanism 3a and the second scraping mechanism 3b.
