Application of glue applicator

(1) Reasonably adjust the coating speed of the glue applicator. In the application, the glue roller should adjust the speed of the rubber roller according to the rubber type and the thickness of the veneer. Under normal circumstances, the glue viscosity of the glue with a higher viscosity should be slower to prevent uneven coating on the surface of the veneer. The glue can be applied faster when the board is glued.

(2) Reasonably adjust the pressure of the rubber roller on the veneer. When the veneer is glued, the proper pressure of the rubberized roller to the veneer is beneficial to the uniformity of the veneer surface of the veneer without leakage, but the pressure applied by the applicator roller should be different for veneers of different thicknesses. For thin veneers, the pressure of the applicator roller on the veneer should be small to prevent the veneer from being crushed. When the glue speed is high, the pressure of the rubber roller on the veneer should be reduced.

(3) Reasonably adjust the gap between the rubberizing roller and the rubberizing roller. There is a difference in rotational speed between the rubberizing roller and the rubberizing roller, which acts to scrape off excess glue on the surface of the rubberizing roller, and can control the amount of glue applied. However, the gap between the two should be properly adjusted according to the rubber type. The gap of the glue with large viscosity should be adjusted larger, and the gap of the glue with small viscosity should be adjusted smaller to prevent the glue from leaking out from the gap.

(4) Reasonably control the amount of glue in the glue tank. The amount of glue in the glue tank has a certain influence on the amount of glue attached to the surface of the rubber coating roller. Generally, the amount of glue in the glue tank should be such that the groove of the lower rubber coating roller is well glued. Too little glue in the glue tank will reduce the glue attached to the surface of the rubberized roller, resulting in uneven distribution or leakage of the rubber layer on the surface of the rubberized veneer; too much glue will cause too much glue on the surface of the rubberized roller. , causing a waste of glue. For a glue applicator with a top extrusion roll, the groove between the upper squeeze roll and the applicator roll is used to store the glue, and the amount of glue in the groove should be reasonably controlled by adjusting the amount of glue applied.
