Description

Technical Field

[0001] The present application relates to the field of digital printing machines, and in particular to a digital printing machine for fabrics. Background Art

[0002] Digital printing machines are a new type of printing equipment. Their working principle is as follows: Through digital printing nozzles, under computer control, digitally process the original print, spraying ink onto the substrate surface to complete the printing process. Digital printing machines are water-saving products. Compared to traditional printing machines, digital printing machines offer the advantages of low pollution, low energy consumption, and short cycle times when printing fabrics.

[0003] Chinese utility model application number CN202321204848.7 discloses an environmentally friendly digital printing machine, comprising a printing table, a printing box disposed on top of the printing table, a feed port and a discharge port provided on the left and right sides of the printing box, a printing assembly disposed on the top of the printing box, and a placement table connected to the top of the printing table. The utility model delivers hot air generated during drying to one of the air ducts, where the hot air in the air duct enters two ironing rollers. The ironing rollers are used to iron the fabric to be printed. The hot air then passes through the ironing rollers into the other air duct, and then into the air guide duct. The hot air then enters a purification box through the air guide duct. The purified air is purified by a purification liquid in the purification box and discharged through an exhaust duct. This facilitates the use of heat generated during drying to iron the fabric to be printed, and also facilitates the purification of exhaust gas generated during drying.

[0004] Before using a digital printing machine to print fabrics, the surface of the fabric is easily contaminated with dust and other impurities. When the digital printing machine prints the fabric, the dust on the surface of the fabric will affect the printing effect of the fabric, resulting in poor printing quality. Utility Model Content

[0005] In order to reduce dust adhering to the surface of fabric and improve the quality of fabric printing, the present application provides a fabric digital printing machine.
