Description
Technical field
The present invention relates to a kind of roll coater, especially a kind of film thickness monitoring is four-roll reverse coater accurately.
Background technology
Roll coater, the full name roll coater.Promptly certain amount of coating is applied to device on the planar material with one group of above revolution roller.Change the pressure between two rollers, can regulate the thickness of coating.Typical roll coater has roll coater, pressure roller coating machine (gravure roll coating machine), positive and negative roll coater etc.
At present, roll coater on the market mostly is three roll reverse coaters greatly, comprise pick-up roller, application roller, metering roll and aluminium strip roller, its application mode is: pick up paint by pick-up roller, give metering roll and application roller, control thickness by the spacing between metering roll and the application roller again, transfer to then on the aluminium volume that is coated.Technology is simple though such coating process has reached to a certain extent, application effect easily, but such shortcoming of bringing is: 1, with present domestic technological level, because the rigidity of metering roll (steel rider) is stronger, therefore the concentric circles of steel rod can reach higher level, but the concentric circles of application roller (rubber roll) has 3～5 microns error, control the thickness of paint with metering roll (steel rider) and application roller (rubber roll), have 3～5 microns error, form membrane thickness unevenness; 2, do not have the bubble of pressure function, the paint tray the inside has bubble, and bubble can be with the application roller, and the plate face that is coated volume forms bubble impression flaw; 3, in the production process, rubber roll works long hours, and the chance retarder thinner is yielding or become big, because of the paint attachment surface of rubber roll is bigger, also can influence the control of thickness.
Summary of the invention
The technical problem to be solved in the present invention is: propose that a kind of defoaming effect is good, the uniform four-roll reverse coater of film thickness monitoring.
The technical solution adopted in the present invention is: a kind of four-roll reverse coater, the band roller that has axis horizontal and first metering roll that be arranged in parallel, second metering roll, application roller and carry band, described second metering roll, first metering roll, application roller and the close side by side successively setting of band roller, the below of described first metering roll, the close pick-up roller that is provided with of axis horizontal, the bottom of described pick-up roller is dipped in the coatings tank.
Specifically, first metering roll of the present invention, second metering roll, band roller and pick-up roller are steel rider, and described application roller is a rubber roll.Described band is coil of strip, yardage roll, aluminium volume or roll of plastic, and band passes between application roller and band roller.In the described coatings tank be liquid state by the roller coat material, the mixture that is specially paint, glue, waterproofing agent or can picked roller picks up.
The course of work of the present invention and operation principle are: by pick-up roller pick up in the coatings tank by the roller coat material, give first metering roll and second metering roll, control thickness by two metering rolls with this, transfer to again on the application roller, transfer to again afterwards on the band that is coated to finish whole roller coat process.
The invention has the beneficial effects as follows: 1, control thickness with two metering rolls, because metering roll is selected steel rider for use, therefore in view of steel rider rigidity is arranged, concentric circles easy to control makes almost zero deflection of thickness, be transferred to the application roller then, even the concentric circles of application roller has 3～5 microns error, but the thickness that is transferred to it be about uniformly, and then be transferred to band, left and right sides thickness also is uniformly, does not just have the thickness deviation; 2, the bubble of pressure function is arranged, twice extruding by pick-up roller and first metering roll and first metering roll and second metering roll has the froth breaking effect; 3, in the production process, rubber roll works long hours, and it is yielding or become big to meet retarder thinner, but rubber roll of the present invention does not directly contact with pick-up roller, so the coating attachment surface of rubber roll is smaller, is not very big to the influence of film thickness monitoring.
Description of drawings
