Problems solved by technology

In this way, an excellent effect in preventing contamination of each end portion of the base film (the portion to which the liquid is not applied) can be observed; however, if the base film has high rigidity, the base film and the coating The adhesion between the rollers becomes poor, and there is a risk that the accuracy of liquid application will be reduced, and there is a risk of damaging the individual end portions of the base film
[0013] Like this, according to the coating device of Japanese Patent Application Publication 5-220430, to preventing thicker coating on each end portion of the base material or to preventing liquid from overflowing the back surface of the base material during high-speed coating, there is no Provides a satisfactory preventive effect, and there is a possibility that the accuracy of the application may decrease due to the placement of parts (i.e., a pair of caps)

Abstract

A liquid application apparatus applies application liquid onto a band-shaped base material that is conveyed continuously. The liquid application apparatus includes: an application cylinder which includes an application section and two small diameter sections having a diameter smaller than the application section, the two small diameter sections being arranged so as to interpose the application section, the application section having an upper portion that is in contact with the band-shaped base material and a lower portion at which the application liquid is supplied, the supplied application liquid on the application section being transferred to the band-shaped base material at the upper portion of the application section while the application cylinder is rotated; a first blade which makescontact with a circumferential surface of the application section of the application cylinder at a contact line, the first blade scraping away an excess of the application liquid on the application section of the application cylinder before the application liquid is transferred to the band-shaped base material; and a second blade which is in contact with circumferential surfaces of the two small diameter sections of the application cylinder.

Description

technical field [0001] The present invention relates to a liquid application device and an inkjet recording device, and more particularly, to a liquid application device in which the liquid excessively applied to the surface of a circular application roller is scraped off by means of a blade to achieve a prescribed application volume, and then The liquid is applied to a base material in a liquid application device such as a gravure roll, a technique for improving coating defects such as coating unevenness and overflow of the liquid onto the back surface of the base material. Background technique [0002] As an inkjet recording method is known, recording is performed by individually ejecting ink droplets from a plurality of nozzles formed in an inkjet head. This type of method has been widely used because it is capable of recording high-quality images on a wide variety of recording media while achieving low operating costs and generating little noise during the recording oper...
