[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] The present application relates to the field of artificial stone processing, and in particular to an artificial stone inkjet processing line. BACKGROUND

[0004] Artificial quartz stone is composed of more than 90% natural quartz and about 10% colorants, resins and other additives for adjusting adhesion, curing, etc. It is a plate material processed by negative pressure vacuum, high-frequency vibration forming, and curing (the temperature is determined according to the type of curing agent). It has a hard texture (Mohs hardness 5-7), a dense structure (density 2.3 g / cm3), and other decorative materials cannot match its wear resistance, pressure resistance, high temperature resistance, corrosion resistance, and impermeability.

[0005] In the existing processing of artificial quartz stone plates, in order to improve the aesthetic appearance of the artificial quartz stone plates, inkjet treatment is performed on the artificial quartz stone plates.

When two curing methods are required in the production line, the artificial quartz stone plates that do not require drying and curing are blocked by the artificial quartz stone plates that require drying and curing, thereby reducing the processing efficiency of the artificial quartz stone plates.
