[0058] The embodiment of the present invention provides a double-beam digital printing machine, in which a winding roller (not shown) conveys the rolled printing medium to a cloth loading mechanism, which, after expansion and tensioning, conveys the printing medium to a guide belt conveying mechanism, which conveys the printing medium to the bottom of a printing carriage 3. Below the printing carriage 3, a linear motor 24 and a mover plate 26 are used to drive the printing carriage 3 to slide between a first beam 21 and a second beam 22, and a nozzle 312 on the printing carriage 3 performs inkjet printing on the printing medium.

Further, the driving of the printing carriage 3 is driven by the linear motor 24 and the mover plate 26 at the same time. The linear motor 24 is located above the beam, has a simple structure, and can easily ensure the installation accuracy and increase the thrust. The mover 265 of the mover plate 26 is energized to generate a magnetic induction effect, which also gives the printing carriage 3 a thrust. At the same time, the mover plates 26 on both sides adopt a parallel control method, which can ensure that the two mover plates 26 are driven synchronously, and the driving force is kept synchronously, and the printing stability and accuracy are effectively guaranteed.

[0059] In some embodiments, Figure 5 and 6As shown, the printing carriage 3 includes a carriage bottom frame 31, a carriage top frame 33 and two carriage side frames 32; the carriage side frames 32 are slidably connected to the second slider 268; a plurality of first nozzle 312 mounting slots 311 are provided on the carriage bottom frame 31, and a plurality of nozzles 312 are arranged one by one on the first nozzle mounting slots 311; the first carriage mounting frames 34 are arranged on the front and rear sides near the top of the carriage side frames 32, and a cartridge rack 35 is connected between the two groups of the first carriage mounting frames 34, and the cartridge rack 35 is located directly above the nozzle 312 and can be used to install ink cartridges; since the number of nozzles 312 exceeds 100, the entire printing carriage 3 exceeds 3 cubic meters, and maintenance becomes a problem; traditional maintenance is to disassemble the entire printing carriage 3, but for more than 100 nozzles 312 If the printing carriage 3 is completely disassembled, firstly, it is inconvenient to disassemble due to its heavy weight, and secondly, it is inconvenient to disassemble due to the large number of nozzles 312. In this embodiment, a maintenance escape opening 36 is formed below the first carriage mounting frame 34. The maintenance escape opening 36 is designed to facilitate maintenance personnel to repair the interior of the printing carriage 3 from the maintenance escape opening 36; the carriage top frame 33 includes a top cross frame 331 and a top vertical frame 332. The top cross frame 331 and the top vertical frame 332 are provided with a wiring groove 333. The top cross frame 331 is also provided with a drop opening 334. The cables can be routed and discharged through the wiring groove 333 and fall into the drop opening 334 to connect the ink cartridge or nozzle 312, making full use of the space of the top frame. At the same time, the cable routing is neat and consistent, which is convenient for maintenance. In order to isolate dust, a dust cover 30 is also provided on the front and rear sides and the top of the printing carriage 3.

[0060] In some embodiments, Figure 5 and 6As shown, the front and rear positions of the trolley side frame 32 near the bottom are provided with a first articulated frame 37, and the front and rear positions of the trolley bottom frame 31 are respectively provided with two sets of second articulated frames 38, and the second articulated frames 38 are provided at the front and rear of the trolley bottom frame 31 and near the middle position; a screw 39, one end of which is hinged to the first articulated frame 37, and the other end is hinged to the second articulated frame 38. In this embodiment, the middle part of the trolley bottom frame 31 is connected to the trolley side frame 32 near the top through the screw 39, and then the screw 39 is rotated to lock it, so that the middle of the trolley bottom frame 31 is given a pulling force by the trolley side frame 32 through the screw 39. When the printing trolley 3 is running, the trolley bottom frame 31 is supported by pulling force on both sides and the middle part to prevent shaking, effectively ensuring the printing accuracy. At the same time, the design of the screw 39 will not affect the maintenance avoidance opening 36. At the same time, the design of the first articulated frame 37, the second articulated frame 38, and the screw 39 needs to consider whether it will add too much weight to the printing carriage 3. The first articulated frame 37, the second articulated frame 38, and the screw 39 in this embodiment are not only compact in structure, but also made of aluminum alloy, which is lighter and has better hardness.

The second slider 268 is driven by the driving mechanism to slide on the second slide rail 267, so that the printing carriage 3 can move up and down along the third direction Z. Furthermore, the length of the stator plate 25 is L2, and the distance between the heads of two adjacent movers 265 is L1, where L1 is an integer multiple of L2. In the embodiment of the present invention, when the mover 265 is energized, a magnetic induction effect is generated, and the printing carriage 3 can be driven and pushed. The printing carriage 3 is driven simultaneously by the linear motor 24 of the double beam and the mover plate 26. Under the premise that the number of nozzles 312 exceeds 100, the mover plate 26 is driven to provide a sufficiently large driving force on the one hand, and on the other hand, the two mover plates 26 are controlled in parallel, which can ensure that the two mover plates 26 are driven synchronously, and the driving force remains synchronized, while being precisely controlled, thereby effectively ensuring printing stability and accuracy; parallel control means that the two mover plates 26 are connected in a parallel circuit, and when the resistance and voltage of the mover plates 26 are the same, the current generated is the same, and the magnetic induction effect of the two mover plates 26 is also the same, thereby ensuring the synchronization of the two mover plates 26.
