Description

Technical Field

[0001] The invention relates to the field of melamine impregnated paper processing, in particular to a melamine impregnated paper gluing device. Background Art

[0002] Melamine impregnated paper usually refers to paper that has been impregnated with melamine resin solution or glue to improve the physical properties, water resistance and wear resistance of the paper. This treatment method can make the paper stronger, waterproof and stain-resistant, and can increase the gloss and hardness of its surface. Melamine impregnated paper is usually used in the production of furniture, decorative panels, flooring and other fields.

[0003] The general production steps can be divided into: preparing melamine glue solution - cleaning the surface of melamine impregnated paper base paper - impregnating paper - drying paper.

[0004] However, the thickness, length and width of melamine impregnated paper are different, and the existing impregnation equipment can only fix and impregnate impregnated paper of fixed thickness, length and width, so the existing impregnation equipment is not very practical.

[0005] In order to solve the above problems, the utility model patent with publication number CN215405325U discloses a gluing device for melamine impregnated paper. The above scheme achieves the effect of fixing melamine impregnated paper of different lengths, widths and thicknesses by setting a pressing component and a placing plate according to the actual length, width and thickness of the melamine impregnated paper to be impregnated, through the coordinated use of the pressing component and the placing plate, thereby solving the problem that the existing gluing equipment can only fix and impregnate impregnated paper of fixed thickness, length and width.

[0006] However, the above method has the following problems that are difficult to solve: 1. During the impregnation process, air bubbles on the surface of the paper and in the glue may adhere to the contact surface between the paper and the glue, so that the part of the paper surface to which the air bubbles adhere cannot contact the glue, thereby forming unevenness or defects, seriously affecting the appearance quality and reducing the overall strength and service life of the product; 2. During the impregnation process, if the paper is thicker, more impregnation time is required to ensure that the inside and outside of the paper are completely and evenly soaked, and the above scheme is difficult to improve production efficiency; 3. The above scheme applies glue by impregnation. The uniformity of this method is affected by many factors, such as glue concentration, impregnation time, etc., and it is difficult to control the coating thickness and uniformity of each piece of paper; after the surface glue loses water and becomes more concentrated, the thickness of the glue layer adhered to the surface of the paper will be uneven, which will waste glue and cause the surface of the finished paper after drying to be uneven, seriously affecting product quality.
