  • Patent number: 11724505
    Abstract: A maintenance system for spray head includes an ink cavity of the spray head communication with the external environment through spray holes. The ink cavity of the spray head is connected with a first accommodating cavity of a first regulating device through a pipeline; when the ink in the ink circulation loop is in a circulating flow state, the ink flows into the ink cavity of the spray head from the first accommodating cavity; because the first accommodating cavity and the ink cavity of the spray head are in a communication state, the change of the first air pressure within the first negative pressure range can make the ink in the first accommodating cavity and the ink cavity of the spray head oscillate at the same time.

  • Publication number: 20220266606
    Abstract: In one embodiment, a high-speed, closed-loop fabric printer comprises a plurality of consecutive stations that can be managed by a single operator. In particular, shirts or other fabric garments may be individually loaded and secured on a pallet by an operator, and the loaded pallets may then cycle through a plurality of unmanned stations positioned along a contiguous path (e.g., oval). The stations may be configured for pretreating the fabric surface, drying and pressing the pretreated fabric with heat, and then inkjet printing a selected image, among others. In this manner, a “wet-to-dry-to-wet” direct to garment (DTG) printing process may thus be achieved, along with optimal controls for maximum adaptability. Furthermore, due to the closed-loop design, a recently printed fabric product returns to the operator to be unloaded at the position in which a new unprinted fabric is loaded, allowing for increased throughput and minimal operator requirements.

  • Publication number: 20200230946
    Abstract: The present invention provides a textile digital printing machine including: a conveying device; a platen which conveys a textile along with the conveying device; a treatment liquid machine, a drying module, a pressing module and a printing module which are arranged successively along a conveying path of the textile. The treatment liquid machine includes a plurality of spray heads for spraying the treatment liquid onto the textile. The drying module is configured to heat the textile which has been sprayed with the treatment liquid, so that the treatment liquid is absorbed by the textile. The pressing module is configured to press the textile to keep the textile flat and heat the platen. The printing module is configured to spray ink onto the textile to thereby print patterns thereon. The heated platen is configured to dry the ink so that the ink is absorbed by the textile.
