Problems solved by technology

Since there is a guide belt under the printed medium, the ink will penetrate into the guide belt and pollute during printing, so a water washing device must be needed to clean the guide belt in time, otherwise the ink on the guide belt will adhere to the medium and cause damage to the medium. Pollution, printing quality cannot be guaranteed
Using a water washing device to clean the guide belt during the printing process will generate a large amount of sewage, which is not only not environmentally friendly, but also increases production costs

Embodiment Construction

[0015] Further description will be made below in conjunction with the accompanying drawings.

[0016] see figure 1 The digital jet printing machine of the present invention shown includes a discharge roller (unwinding device) 4, a rear tensioning device 3, a pressure roller 2, a driving roller 1, and an inkjet printing device arranged in sequence along the moving direction of the medium 13. 12. Heating and drying device 10 , main drive roller 9 , expansion roller 8 , rewinding tension roller 5 , front tensioning device 6 , and rewinding roller 7 . The rewinding roller 7 and the rewinding tension roller 5 constitute a rewinding device. The pressure roller 2 is pressed against the circumferential direction of the driving roller 1.

[0017] A collecting tank (waste ink collecting device) 11 is provided under the reverse side of the medium, opposite to the print head of the inkjet printing device 12 arranged above the front side of the medium. The heating and drying device 10 i...

Abstract

The invention provides a digital jet printing machine which not only does not have a belt guide device and a washing device, but also can guarantee the printing quality, protect environment and can reduce cost. The digital jet printing machine comprises a front tension device and a rear tension device which are arranged at the front end and the rear end of a medium and tension the medium, an inkjet printing device used for printing patterns at the front surface of the tensioned medium, and a waste ink collecting device which is arranged at the lower part of the reverse side of the medium withprinted patterns and is used for collecting ink leaking from the reverse side of the medium. The invention also provides a digital jet printing method.

Description

technical field [0001] The invention relates to a textile digital jet printing machine, in particular to a water-free digital jet printing machine, which is suitable for any field requiring textile printing. Background technique [0002] Chinese patent ZL02107229.9 discloses a belt-guiding type digital jet printing machine, which mainly includes an unwinding device, a spreading device, an inkjet printing device, a belt-guiding device, and a winding device arranged in sequence. The guide belt device consists of two drive rollers and a guide belt coated with guide belt glue on the surface. The medium is pasted on the guide belt and the two drive rollers drive the guide belt to move the medium. At the same time, the printing device sticks to the guide belt. Print the pattern on the front side of the media. It increases equipment cost because of the guide belt device. Since there is a guide belt under the printed medium, the ink will penetrate into the guide belt and pollute d...
