Uniform gluing device

Abstract

The invention discloses a uniform gluing device, which comprises a machine frame, a right stand, a left stand, a crossbeam, a cylinder, a supporting plate, an elastic column whose number is not less than 2 evenly distributed along the supporting plate, a guide rod, Nylon pressure roller, material pushing mechanism, material distributing mechanism, coating mechanism, speed-adjusting motor, transmission mechanism, feed connecting pipe, glue is pumped into the material distributing mechanism through the feeding connecting pipe, and the pushing mechanism pushes the glue to be evenly discharged through the material distributing mechanism , the speed regulating motor works to drive the material distributing mechanism to rotate continuously, and the glue hanging groove set on the surface of the metal roller absorbs the glue discharged from the material distributing mechanism evenly. Contact, the elastic column deformation reaction acts on the nylon pressure roller, so that the material is in close contact with the coating mechanism, and the metal roller evenly coats the glue attached to the surface and the material. The device has a simple structure, can automatically compress materials, quantitatively, uniformly and continuously apply glue, and has good sealing performance and a high degree of automation.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a uniform gluing device. Background technique [0002] Composite flooring and composite woodworking boards are generally composed of an intermediate matrix and a surface wear-resistant layer. The intermediate matrix is ​​made by crushing logs, adding glue, preservatives, additives, and pressing them with high temperature and high pressure with a hot press, so it breaks the logs. The physical structure overcomes the weakness of poor log stability. The surface wear-resistant layer is made of surface paper with wear-resistant aluminum oxide impregnated with melamine resin. It is a key part that determines the life of laminate flooring. [0003] During processing, the surface of the intermediate substrate is first coated with glue, and then the surface wear-resistant layer and the intermediate substrate are hot-pressed. There are two main methods of applying glue to the intermediate substrate. ...

Problems solved by technology

[0003] During processing, the surface of the intermediate substrate is first coated with glue, and then the surface wear-resistant layer and the intermediate substrate are hot-pressed. There are two main methods of applying glue to the intermediate substrate. The first is manual gluing, which is not only uneven, but also efficient. Low, the second is machine gluing, the gluing principle is: the motor drives the gluing roller to rotate continuously, the lower part of the gluing roller is immersed in the glue solution, and the continuously rotating gluing roller applies the glue solution to when it is continuously fed The surface of the intermediate substrate, due to the uneven distribution of the glue solution dipped into the glue solution by the gluing roller on the surface of the gluing roller, resulting in uneven coating
