For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0019] like Figure 1-2 As shown, a digital printing machine of a preferred embodiment of the utility model comprises a frame 1, a conveying assembly 2 arranged on the frame 1, a working platform 3, a nozzle trolley 5, a winding mechanism and an unwinding mechanism, wherein the conveying assembly 2 comprises an active roller 21 and a driven roller 22 arranged opposite to each other, a conveying belt 23 is connected between the active roller 21 and the driven roller 22, the working platform 3 is arranged between the active roller 21 and the driven roller 22, and the upper surface of the working platform 3 is in contact with the inner surface of the conveying belt 23, the winding mechanism and the unwinding mechanism are respectively arranged at both ends of the frame 1, and when a coil 4 is connected between the winding mechanism and the unwinding mechanism, the coil 4 is in contact with the outer surface of the conveying belt 23, and the nozzle trolley 5 is movably arranged on the frame 1 corresponding to the working platform 3. The nozzle trolley 5, the working platform 3 and the conveying assembly 2 are all arranged between the winding mechanism and the unwinding mechanism.
[0020] The digital printing machine based on the above technical features is provided with a working platform 3 between the active roller 21 and the driven roller 22, and the upper surface of the working platform 3 is in contact with the inner surface of the conveyor belt 23. At the same time, a winding mechanism and an unwinding mechanism are respectively provided at both ends of the frame 1. When a coil 4 is connected between the winding mechanism and the unwinding mechanism, the coil 4 is in contact with the outer surface of the conveyor belt 23. When the coil 4 needs to be printed, the coil 4 is directly placed on the unwinding mechanism, and the coil 4 is transported by the conveyor belt and wound on the winding mechanism, and is printed by the nozzle carriage 5 during the transportation process. When a flat product needs to be printed, the product is directly placed on the conveyor belt 23 for printing, thereby realizing that both the coil 4 and the flat product can be printed, thereby greatly improving the application range of the printing machine.
[0021] In this embodiment, the nozzle trolley 5 includes a trolley body 51 movably arranged on the frame 1, and a nozzle and a powder spreading mechanism 52 are arranged on the trolley body 51. A plurality of nozzles can be provided, and the plurality of nozzles are used to spray inks of different colors to ensure the printing effect. The powder spreading mechanism 52 is used to spread powder, thereby realizing the two functions of printing and powder spreading, and improving the final effect of the product.
[0022] In this embodiment, longitudinal beams 11 are respectively provided at both ends of the working platform 3, and the two longitudinal beams 11 are connected with cross beams 12 that can move laterally relative to the working platform 3, and the nozzle carriage 5 can be arranged on the cross beams 12 to move longitudinally relative to the working platform 3. When the nozzle carriage 5 needs to move laterally, the nozzle carriage 5 can move along the cross beams 12; when the nozzle carriage 5 needs to move longitudinally, the cross beam 12 moves along the longitudinal beams 11, so that the nozzle carriage 5 follows the cross beam 12 to move longitudinally. Since printing is a precision process, the accuracy of printing needs to be guaranteed. If the cross beam 12 is made of steel, the steel will be deformed to a certain extent during long-term use, which will eventually affect the printing effect. Therefore, the material of the cross beam 12 can be made of marble, and the marble will not fall or deform, thereby ensuring the accuracy of printing.
[0023] The printing methods of the printing machine of the utility model include multi-PASS scanning printing and ONEPASS continuous printing. ONEPASS means that when the substrate is being retracted and released, the marble beam 12 does not move in the Y axis (longitudinal direction), and the nozzle and the powder spreading mechanism 52 only move left and right in the X axis on the marble beam 12 to complete the printing and powder spreading; when the reel and the conveyor belt 23 are intermittently driven, the marble beam 12 moves in the Y axis, and the nozzle and the powder spreading mechanism 52 move left and right in the X axis. After a certain area is printed, the reel is retracted and printed.
[0024] In this embodiment, the winding mechanism includes a winding roller 8 and a first guide roller 6 disposed above the winding roller 8. One end of the winding roller 8 is connected to a driving mechanism, and the driving mechanism drives the winding roller 8 to rotate to achieve winding of the coil 4. The driving mechanism can be a motor. The unwinding mechanism includes an unwinding roller 9 and a second guide roller 7 disposed above the unwinding roller 9. The first guide roller 6 and the second guide roller 7 are at the same horizontal height.
[0025] In this embodiment, the reeling mechanism and the unwinding mechanism can be detachably connected to the frame 1. When printing a flat product, the reeling mechanism and the unwinding mechanism can be disassembled; or they can be left unassembled, but the coil can be left uninstalled. When the connection is disassembled, a mounting groove can be provided on the frame 1, and the reeling mechanism and the unwinding mechanism can be detachably connected to the mounting groove. Specifically, there are a plurality of mounting grooves, and the first guide roller 6, the second guide roller 7, the reeling roller 8, and the unwinding roller 9 are all provided in the corresponding mounting grooves.
[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
