Compound pressing roller mechanism of novel coating machine

Abstract

The invention discloses a compound pressing roller mechanism of a novel coating machine. The mechanism comprises a frame, a compound roller, a pressing roller and a back pressure roller, wherein the compound roller is rotationally mounted on the frame; two ends of the pressing roller are rotationally mounted on a first slide base; the first slide base is slidingly mounted on the frame; two ends of the back pressure roller are rotationally mounted on a second slide base; the second slide base is slidingly mounted on the frame; the compound roller, the pressing roller and the back pressure roller are arranged side by side; and the pressing roller is positioned between the compound roller and the back pressure roller. The pressing roller and the compound roller can be singly used; if the force applied to the pressing roller is insufficient or the pressing roller is deformed, the back pressure roller can be stacked based on the pressing roller; the back pressure roller extrudes the pressing roller to correct the bending deformation of the pressing roller, so that the whole roller surface of the pressing roller is more uniform; and meanwhile, more extrusion force can be provided, so that the pressing quality can be guaranteed, and the development requirements of high-precision coating machine compound product quality are met.

Description

Technical field [0001] The invention relates to the field of coating machines, in particular to a new type of coating machine composite pressing roller mechanism. Background technique [0002] The existing coating machine composite pressing roller mechanism mostly adopts single-cylinder direct pressure, single-cylinder swing arm pressing and double-cylinder swing arm pressing mechanism; among them, the single-cylinder pressing mechanism has simple structure and low cost. However, its pressing force should not be too large, otherwise it will easily cause the rubber pressing roller to bend and deform, forming an arch bridge, resulting in poor bonding between the two substrates; the double-cylinder swing arm pressing mechanism has a complex structure. During the pressing process, With the change of its swing angle, the stress point of the roller surface also changes, resulting in the pressing force is not a constant value, affecting the pressing quality; it can be seen that the trad...

[0002] The existing coating machine composite roller mechanism mostly adopts single-cylinder direct pressure, single-cylinder swing arm pressing, and double-cylinder swing arm pressing mechanisms; among them, the single-cylinder pressing mechanism has simple structure and low cost. However, the pressing force should not be too large, otherwise it will easily cause the rubber roller to bend and deform, forming an arch bridge shape, resulting in poor bonding between the two base materials; the double-cylinder swing arm pressing mechanism has a complex structure, and it should be As the swing angle changes, the stress point of the roller surface also changes, resulting in a non-constant pressing force and affecting the pressing quality; it can be seen that the traditional cylinder structure cannot adapt to the development requirements of the quality of high-precision coating machine composite products ; For this reason the present invention provides a kind of composite roller mechanism of novel coating machine for solving the above-mentioned technical problems
