A digital printing machine for wide-width polyester wall covering

Abstract

The invention relates to the field of printing equipment, in particular to a digital printing machine for wide-width polyester wall coverings. The above technical purpose of the present invention is achieved through the following technical solutions: a digital printing machine for wide-width polyester wall coverings, including a frame, a printing device on the frame, a transmission device and a The heating device on the frame, the heating device includes a fixed area and a low-temperature preheating area connected to the frame in sequence according to the conveying direction of the polyester wall covering and located between the unwinding drum and the winding drum And medium temperature fixing area. The purpose of the present invention is to provide a digital printing machine for wide-width polyester wall covering, which has a simple structure and is convenient for implementation. Wide-width polyester wall coverings require low-temperature color development, medium-temperature color fixation, and drying and heat dissipation.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a digital printing machine for wide-width polyester wall coverings. Background technique [0002] As a more and more popular decoration material nowadays, polyester wide-width wall coverings are widely used in conference rooms, hotel lobbies, mid-to-high-end residences and other places. There are two ways to color polyester wide-width wall coverings in the market. One is knitting Jacquard, this kind of wall covering has a concave-convex three-dimensional effect and is exquisite, but the disadvantage is that knitted jacquard is restricted by modern technology and its own characteristics, and cannot make bright colors and complex patterns. Another way is to use digital printing, digital printing Printing technology is widely used in the clothing industry, such as printing various bright patterns on T-shirts. Using digital printing technology on wall coverings, conventional digita...

[0002] Polyester wide-width wall coverings are becoming more and more popular decoration materials nowadays, and are widely used in conference rooms, hotel lobbies, mid-to-high-end residences and other places. There are two ways to color polyester wide-width wall coverings in the market, one is knitting Jacquard, this kind of wall covering has a concave-convex three-dimensional effect and is exquisite, but the disadvantage is that knitted jacquard is restricted by modern technology and its own characteristics, and cannot make bright colors and complex patterns. Another way is to use digital printing, digital printing Printing technology is widely used in the clothing industry, such as printing various bright patterns on T-shirts

Using digital printing technology on wall coverings, conventional digital printing machines are still used in the prior art, such as a new type of digital printing machine disclosed in the Chinese patent document CN201320383208.7, which includes a transmission system, a printing system, and a heating system , but polyester wide-width wall coverings are different from ordinary materials, and the heating process is complicated, requiring steps such as low-temperature color development, medium-temperature color fixing, drying and heat dissipation, which cannot be realized efficiently by ordinary digital printers; on the other hand, polyester wide-width wall coverings are high in weight and large in size , the general width is about 3.2 meters, the material of such size and weight is easy to be uneven in the process of conveying and heating, which will affect the printing effect
