Problems solved by technology

The utility model is novel in concept, simple in structure, low in cost, fast and convenient in the coating process, double-sided coating is completed once, and the coating is uniform. The paint that occurs when the thinner and looser fabrics penetrate into the reverse side of the fabric, the thickness of the coating is different, and the coating effect is poor, which makes it possible for the knife coater to coat such fabrics. Suitable for coating thin, stretchy knitted fabrics

Embodiment Construction

[0006] The present invention includes a cylinder 1, a platform 2, an upper scraper 3 and a fabric pulling device 4, etc., wherein the needle plate pulling device 4 can pull the fabric to pass between the platform 2 and the upper scraper 3, and is characterized in that: the upper scraper 3 Back scraper 5 is equipped with, and lower scraper 5 is positioned at the below of fabric 7, and the coating that seeps through fabric 7 is scraped evenly. A receiving hopper 6 is installed below the lower scraper 5 to receive the coating scraped by the lower scraper 5 . Described fabric pulling device 4 is generally needle plate pulling device. In actual coating, in order to obtain a good coating effect, one or more upper scrapers and lower scrapers can be installed according to the characteristics of the coating and the coating situation. Generally, the upper and lower scrapers are installed alternately in groups to compare the effect Well, that is, one upper scraper and one lower scraper ...

Abstract

A multi-blade coater for fabric is composed of drum, platform, upper and lower coating blades and fabric pull unit. It features that the fabric can be pulled by the fabric pull unit to pass it through the gap between upper and lower blades along the platform. Its advantages are simple structure high coating speed, coating both surfaces and high coating uniformity.

Description

Technical field: [0001] The invention relates to a fabric coating process, in particular to a multi-knife coating process suitable for double-sided coating of thinner and sparser fabrics. Background technique: [0002] The knife coater is favored by many manufacturers because of its simple structure, convenient operation and low cost. When coating, it only needs to use a needle plate to pull the fabric to pass between the platform and the scraper, and the excessively accumulated paint on the back of the scraper can be removed. Uniformly coated on the surface of the fabric, at present, most of the gluing and other processes of fabrics are realized by knife coating; however, this coating method has problems when coating those thinner and looser fabrics, Due to the large gap between the warp and weft of the fabric, the excessively accumulated paint on the back of the scraper can easily penetrate into the reverse side of the fabric, making the thickness...
