Problems solved by technology

[0003] However, at present, the Chinese market cannot produce 3300mm wide sublimation digital transfer printing paper, which is limited by the preparation process of large-width sublimation digital transfer printing paper. Due to the small thickness of the coating and the excessive width of the printing paper, The paint feeding speed will be very slow, which seriously affects the production efficiency. Therefore, the commonly used method is to mix the paint with water to form a water-based paint. However, the printing paper is prone to warping during the water evaporation process, which greatly affects the molding quality of the printing paper. and the effect of using

Abstract

The invention relates to the technical field of a coating process, and discloses a coating machine for preparing digital transfer printing printed paper and a preparation method thereof. The coating machine comprises a double-layer machine frame, wherein the lower layer of the double-layer machine frame is provided with an automatic paper collecting and paper putting frame and a prepositive soft scraping cutter coating device; the upper layer is provided with a hot air drying system; the lower layer is provided with a rear-mounted soft scraping cutter coater, a drying group and an automatic paper collecting frame; paint is stored in the prepositive soft scraping cutter coater and is used for performing paint layer covering on the front side of raw paper; glue materials are stored in the rear-mounted soft scraping cutter coater and is used for performing glue material layer covering on the back side of the raw paper. In the processing, the paint is properly coated through layer coatingin one step; the glue materials provide the protection on the back side of the raw paper; the deformation due to stress in the raw paper drying process can be reduced. The hot sublimation digital transfer printing printed paper with the wide breadth being 3300mm can be produced; the work turning speed can reach 120 m / min; the soft scraping cutter coating modes are used as both the front side and the back side of the raw paper; the coating uniformity of the printed paper is ensured; the tilting deformation and edge curling of the printed paper are reduced; the appearance is flat and attractive.

Description

technical field [0001] The invention relates to the technical field of coating technology, in particular to a coating machine for preparing digital transfer printing paper and a preparation method thereof. Background technique [0002] Sublimation digital transfer printing paper is a very popular carrier for paper preparation. The transfer printing technology used in it can print the pattern on the printing paper first, and then print the pattern on the product after transfer, so as to realize the accurate reproduction of the pattern. With the improvement of people's requirements for product packaging and decoration, the use of sublimation digital transfer printing paper is becoming more and more extensive. Because it is not limited by media, low cost, easy to operate, and environmentally friendly, it has attracted widespread attention. [0003] However, at present, the Chinese market cannot produce 3300mm wide sublimation digital transfer printing paper, which is limited by...
