20180326715
The present disclosure relates to the field of printing, and more particularly, to a printing device, and a printing method.
In the printing and dyeing industry, darker media need to be sprayed and printed with a layer of light-colored underpainting in advance, and then the underpainting is sprayed and printed with patterns, so that it's possible to avoid the color of the media from covering the patterns. In the prior art, the medium is firstly placed on a silk net printing machine for printing with underpainting, then it is placed on an ink jet printing machine for spraying and printing the pattern. However, the silk net printing machine and the ink jet printing machine need to be purchased in this case, which greatly increases the enterprise cost; and according to different technologies, the medium needs to be transferred among different equipment, which limits the improvement of the production efficiency.
In order to overcome the deficiencies in the prior art, the present disclosure provides a printing device based on digital printing.
The present disclosure further provides a printing method.
In order to solve the above technical problems, the disclosure employs technical solutions as follows:
A printing device based on digital printing comprises a rack and a platen, wherein the rack is sequentially provided with a plurality of functional zones, the functional zones comprise a feeding zone, an underpainting printing zone, a pattern printing zone and an unloading zone. the platen is used for placing a medium to be printed, and is transferred among the feeding zone, the underpainting printing zone, the pattern printing zone and the unloading zone to achieve a continuous printing process.
As a further improvement of the foregoing solution, the functional zones further comprise a pre-treating fluid spraying zone arranged between the feeding zone and the underpainting printing zone.
As a further improvement of the foregoing solution, the functional zones further comprise a drying zone arranged between the pre-treating fluid spraying zone and the underpainting printing zone, and/or between the underpainting printing zone and the pattern printing zone.

The platen is used for fixing the medium to be printed. The medium is commonly a ready-to-wear or a cutting piece. Before printing, a binding element is coated manually or by a mechanism on a supporting plane of the platen, and then the medium is evenly placed on a binding surface. After the medium is fixed, the platen is moved to the underpainting printing zone 200 from the feeding zone 100, the underpainting is printed on the medium through the underpainting digital printing device; the platen is moved to the pattern printing zone 300 after completing the underpainting printing, patterns are printed on the underpainting through the pattern digital printing device; the platen is moved to the unloading zone 400 for unloading operation after printing the patterns; and then the platen is returns to the feeding zone 100 to wait for next feeding. Only a digital printing device is needed according to the present disclosure to complete the underpainting and pattern printing, without incorporating a silk net printing machine and an ink jet printing machine, which is advantageously saving the enterprise cost, omitting a step of materials transferring among different equipment, and improving the production efficiency.
Preferably, the feeding zone 100, the underpainting printing zone 200, the pattern printing zone 300 and the unloading zone 400 are annularly distributed, in particular, elliptically distributed, such that the space occupation of the equipment can be reduced.
Preferably, the embodiment comprises at least four platens, namely, each functional zone corresponds to at least one platen. After the platen in the feeding zone 100 is loaded with the medium and accesses into the underpainting printing zone 200, the platen in the unloading zone 400 can access into the feeding zone 100 for feeding operation in time, thus a continuous printing process is achieved, which further improves the production efficiency.
In the above various embodiments, it is preferably ensured that the quantity of the platens is not less than that of the functional zones, so that the platen in the unloading zone 400 can access into the feeding zone 100 in time after the platen in the feeding zone 100 accesses into the next functional zone.
According to the present disclosure, various additional functional zones can be arranged in different positions of the rack according to different process, which will not be elaborated herein.
