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 coating technology, and discloses a coating machine for preparing digital transfer printing paper and a preparation method thereof, which includes a double-layer frame, and the lower layer of the double-layer frame is equipped with an automatic paper receiving and placing frame and a paper frame. The front soft blade coater is equipped with a hot air drying system on the upper layer, and the rear soft blade coater, drying group and automatic paper receiving rack are installed on the lower layer; the front soft blade coater stores paint and is used for The front side of the base paper is coated with paint; the rear soft scraper coater stores rubber material and is used to coat the back side of the base paper with rubber material. During processing, the coating is in place at one time, and the rubber provides back protection for the base paper, reducing the deformation of the base paper caused by internal stress during the drying process. The invention can produce thermal sublimation digital transfer printing paper with a width of 3300mm, and the working speed can reach 120m / min. Both sides of the base paper adopt the soft scraper coating method, which ensures uniform coating of the printing paper and reduces printing Paper warping and curling, more flat and beautiful.

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...
