Problems solved by technology

The original coating device is easy to penetrate when coating, especially when the viscosity of the coating is low
In addition, because the fabric is prone to uneven longitudinal tension, the coating after coating is prone to blooming due to uneven tension or the rotation of the back roll, and then uneven coating or excessive thickness of the coating will affect the electrical and magnetic conductivity of the original material. , thermal conductivity and other properties

Abstract

The invention discloses a coating device for permeable base materials. The coating device comprises coating base materials, back rolls and a feeding and scraping mechanism, wherein the coating base materials are transmitted by the back rolls; the feeding and scraping mechanism is mounted under the coating base materials, and comprises a feeding tank and a scraping knife; a feeding opening is formed in the upper end of the feeding tank; and the scraping knife is mounted on one side of the feeding tank. The coating device disclosed by the invention is resistant to permeation and uniform in coating, and the phenomena of blurring, grains and the like on the surface due to uneven tension of coating or rotation problem of a guide roller are avoided.

Description

technical field [0001] The invention relates to the field of coating devices, in particular to a coating device for permeable substrates. Background technique [0002] With the increasing development of electronic products and daily necessities, the requirements for material coating are getting higher and higher. In recent years, with the development and application of flexible electronic products and wearable devices, various polyester fabrics with electrical, magnetic and thermal conductivity, Substrates such as non-woven fabrics have also begun to be widely used in the coating industry. The technical difficulty of coating this type of substrate lies in the permeability of the substrate. The penetration of the coating liquid not only affects the appearance of the material but also has a great destructive effect on the performance of the material, and the particles produced by the penetration are also There are significant constraints on the coating process and the apparen...
