Large inkjet flatbed table
View Patent ↗A method of manufacturing of an inkjet flatbed table including a large support layer with an area of at least 1.5 m 2 to support an ink receiver in an inkjet printing system, the method including the steps of fixing a plate on top of a base unit by forming a part of or whole the support layer; and abrading the fixed plate to have a flatness on the top of the support layer less than 300 μm and wherein the plate is characterized by including a thermoplastic polymer resin.
1. A method of manufacturing an inkjet flatbed table including a support layer having an area of at least 1.5 m 2 to support an ink receiver in an inkjet printing system, the method comprising the steps of:
fixing a plate on top of a base to define a portion or an entirety of the support layer; and
abrading the fixed plate to have a flatness on a top of the support layer less than 300 μm; wherein
the plate includes a thermoplastic polymer resin.
2. The method of manufacturing an inkjet flatbed table according to claim 1 , wherein the plate includes an engineering plastic composition or polyethylene terephthalate (PET), polyamide (PA), high-density polyethylene (HDPE), polytetrafluoroethylene (PTFE), polyoxymethylene (POM), and/or Polyaryletherketone (PAEK).
3. The method of manufacturing an inkjet flatbed table according to claim 1 , wherein the base includes a plate including a honeycomb structure.
4. The method of manufacturing an inkjet flatbed table according to claim 1 , wherein the step of abrading the fixed plate includes:
abrading the fixed plate such that the support layer is parallel or substantially parallel to a reference plane which is determined by a set of reference points in or on the base.
5. The method of manufacturing an inkjet flatbed table according to claim 1 , further comprising the step of:
attaching a vacuum chamber underneath the inkjet flatbed table to create a vacuum pressure between an ink receiver and the inkjet flatbed table by sucking air through a channel attached to an aperture in the plate and to an aperture in the base; wherein
the inkjet flatbed table is porous.
6. The method of manufacturing an inkjet flatbed table according to claim 5 , wherein the aperture in the plate includes a chamfered outlet in a top of the plate.
7. The method of manufacturing an inkjet flatbed table according to claim 5 , further comprising the step of:
wrapping a porous conveyor belt around the inkjet flatbed table; wherein
the porous conveyor belt is operatively connected to a plurality of pulleys.
8. The method of manufacturing an inkjet flatbed table according to claim 7 , further comprising the step of:
attaching an air-blowing chamber underneath the inkjet flatbed table to create a pressure between the porous conveyor belt and the inkjet flatbed table by blowing air through a channel attached to another aperture in the plate and to another aperture in the base.
9. The method of manufacturing an inkjet flatbed table according to claim 1 , wherein the step of fixing the plate includes gluing and/or screwing the plate on top of the base.
10. An inkjet flatbed table comprising:
a support layer with an area of at least 1.5 m 2 to support an ink receiver, the support layer including a set of plates including a thermoplastic polymer resin; and
a base; wherein
the support layer has a flatness less than 300 μm;
the set of plates are fixed to the base;
the set of fixed plates fixed to the base include abraded surfaces.
11. The inkjet flatbed table according to claim 10 , wherein each plate of the set of plates includes an engineering plastic.
12. The inkjet flatbed table according to claim 10 , wherein the base includes a plate including a honeycomb structure.
13. The inkjet flatbed table according to claim 10 , wherein the inkjet flatbed table is porous and includes:
a vacuum chamber underneath the inkjet flatbed table to create a vacuum chamber between the ink receiver and the inkjet flatbed table by sucking air through a channel attached to an aperture in the plate and to an aperture in the base; wherein
the aperture in the plate includes a chamfered outlet at a top of the plate.
14. The inkjet flatbed table according to claim 13 , further comprising:
a porous conveyor belt wrapped around the inkjet flatbed table; wherein
the conveyor is operatively connected to a plurality of pulleys.
15. The inkjet flatbed table according to claim 14 , further comprising:
an air blower underneath the inkjet flatbed table to create a pressure between the porous conveyor belt and the inkjet flatbed table by blowing air through a channel attached to another aperture in the plate and to another aperture in the base.
