Problems solved by technology

[0002] The drum coater usually applies glue to the base material through a gluing wheel, and then sends the base material into the heating device for heating and curing to make a finished product; in order to save the amount of glue used, the gluing wheel and the oven A squeegee device is arranged between them. The existing squeegee device usually rolls on the rubberized surface of the base material by a rotatable wire rod. The wire rod is a rod whose outer surface is wound with a steel wire along the thread direction. There are gaps between each circle of steel wires and the outer surface of the wire rod has spiral continuous grooves; when gluing, it is necessary to apply more glue on the substrate, and roll the wire rod on the surface of the substrate to make the excess The glue flows along the direction of the thread groove and flows out along the thread groove. After scraping the glue, a uniform thickness and continuous glue coating layer is obtained on the substrate. However, in order to ensure the adhesion of the substrate, it must be on the substrate when applying glue. Apply thicker glue, so its glue-saving effect is not ideal

Embodiment Construction

[0014] See attached figure 1 Shown, a kind of squeegee device of coater, this squeegee device is arranged on the gluing head equipment of coater, and is positioned between upper rubber wheel 14 and oven, passes quantitative roller 15 on upper rubber wheel 14 The control of glue amount, base material 2 can be coated evenly after gluing, and the gluing surface of glue layer is thinner; A pressurizing mechanism, the bracket 1 is also provided with a squeegee stick 11, and the squeegee stick 11 and the pressurizing mechanism are used for the substrate 2 after gluing from the squeegee stick 11 It passes between the pressurizing mechanism, and the glued surface of the substrate 2 is pressed on the outer surface of the squeegee rod 11 .

[0015] The circumferential surface of the squeegee stick 11 has a plurality of grooves 19 arranged along the axial direction of the squeegee stick 11, and each of the grooves 19 surrounds a closed circle around the axis of the squeegee stick 11, re...

Abstract

A scraper unit for coater is arranged on the coating head between the adhesive applying wheel and baking oven. It is composed of supporting frame, pressing mechanism and adhesive scraping roller on said supporting frame. The coated substrate passes through the gap between said adhesive scraping roller and pressing mechanism for squeezing the adhesive from convex position to concave position, so ensuring sufficient adhesion with less consumption of adhesive.

Description

technical field [0001] The invention relates to a squeegee device applied to a roller coating machine. Background technique [0002] The drum coater usually applies glue to the base material through a gluing wheel, and then sends the base material into the heating device for heating and curing to make a finished product; in order to save the amount of glue used, the gluing wheel and the oven A squeegee device is arranged between them. The existing squeegee device usually rolls on the rubberized surface of the base material by a rotatable wire rod. The wire rod is a rod whose outer surface is wound with a steel wire along the thread direction. There are gaps between each circle of steel wires and the outer surface of the wire rod has spiral continuous grooves; when gluing, it is necessary to apply more glue on the substrate, and roll the wire rod on the surface of the substrate to make the excess The glue flows along the direction of the thread groove...
