[0039] like Figures 1 to 4 As shown, the embodiment of the present invention provides a double-beam mechanism of a digital printing machine, comprising: a main frame 1, which is mainly used to install the active roller, passive roller and belt of the feeding material, etc., which are not repeated here; a first beam 21 and a second beam 22 are arranged on it, and the first beam 21 and the second beam 22 are arranged parallel to each other, and the first beam 21 and the second beam 22 form a double beam, preferably the first beam 21 and the second beam 22 are marble beams; a printing carriage 3, on which a plurality of nozzles 8 are arranged, in this embodiment, mainly For digital printing machines with multiple printheads 8, particularly those with more than 100 printheads 8, the print carriage 3 is slidably mounted between the first beam 21 and the second beam 22. A linear motor 4 is also mounted on each of the first and second beams 21, 22, with its output connected to the print carriage 3. The linear motor 4 is primarily conventional and will not be further elaborated here. Stator plates 5 are mounted along the length of the first and second beams 21, 22, with mover plates 6 connected to either side of the print carriage 3. When power is applied to the mover plates 6, the print carriage 3 moves in response to the magnetic field.

[0040] This embodiment of the utility model provides a dual-beam mechanism for a digital printing machine. The printing carriage 3 is slidably arranged between a first beam 21 and a second beam 22. The first beam 21 and the second beam 22 ensure the stability of the printing carriage 3 during sliding while maintaining precision. Furthermore, the printing carriage 3 is driven by a linear motor 4 and a mover plate 6, achieving more accurate movement and effectively ensuring printing accuracy.

[0041] In some embodiments, as Figure 4 As shown, in order to ensure the stability of the operation of the printing carriage 3, the top and side surfaces of the first crossbeam 21 and the second crossbeam 22 are both provided with slide rails 23; the movable plate 6 includes a movable vertical plate 62 and a movable horizontal plate 61, the top of the movable vertical plate 62 is connected to the movable horizontal plate 61, and the movable horizontal plate 61 and the movable vertical plate 62 are both provided with sliders 63 corresponding to the slide rails 23. In this embodiment of the utility model, the printing carriage 3 slides between the first crossbeam 21 and the second crossbeam 22 through the cooperation of the slide rails 23 and the sliders 63. At the same time, the slide rails 23 are respectively provided with the top and side surfaces of the first crossbeam 21 and the second crossbeam 22. For such a heavy printing carriage 3, the lifting force in two directions is applied, so that the printing carriage 3 has less resistance during operation and moves more stably and smoothly.

[0042] In some embodiments, as Figure 4 As shown, in order to increase the stress of the mover plate 6, a reinforcement block 7 is provided at the connection position of the mover transverse plate 61 and the mover vertical plate 62. One side of the reinforcement block 7 is connected to the mover transverse plate 61, and the other side of the reinforcement block 7 is connected to the mover vertical plate 62.

[0043] In some embodiments, as Figures 2 to 4 As shown, the printing carriage 3 includes a base frame 31, a top frame 33, and two side frames 32. The side frames 32 are connected to the mover plate 6. The base frame 31 is provided with a plurality of first mounting slots 311, which correspond one-to-one with the printheads 8 and are installed one-to-one within the first mounting slots 311. Furthermore, to fully utilize the internal space of the printing carriage 3, first mounting brackets 34 are provided on the front and rear sides of the side frames 32 near the top. An ink cartridge rack 35 is connected between the two sets of first mounting brackets 34. The ink cartridge rack 35 is located directly above the printheads 8 and can be used to install ink cartridges. Furthermore, since the number of printheads 8 exceeds 100, the entire printing carriage 3 exceeds 3 cubic meters, making maintenance a challenge. Traditional maintenance requires disassembly of the entire printing carriage 3. However, for a printing carriage 3 with more than 100 printheads 8, disassembly is inconvenient due to its heavy weight and the large number of printheads 8. In this embodiment, a maintenance escape opening 36 is formed below the first mounting frame 34 . The design of the maintenance escape opening 36 allows maintenance personnel to conveniently perform maintenance on the interior of the printing carriage 3 through the maintenance escape opening 36 .

[0044] In some embodiments, as Figure 3As shown, since the number of printheads 8 exceeds 100, the base frame 31 must bear a significant weight. Side frames 32 are provided on either side of the base frame 31 to support it. However, the center portion of the base frame 31 bears a significant weight, and the swaying of the printheads 8 directly affects printing accuracy. In this embodiment, first articulated frames 37 are provided at the front and rear of the side frames 32, near the bottom. Two sets of second articulated frames 38 are provided at the front and rear of the base frame 31, near the center. A screw 39 is hinged at one end to the first articulated frame 37 and at the other end to the second articulated frame 38. In this embodiment, screws 39 connect the middle portion of the base frame 31 to the side frames 32 near the top. Screws 39 are then rotated and tightened. This allows the middle portion of the base frame 31 to be tensioned by the side frames 32 via screws 39. During operation, the base frame 31 is supported by tension on both sides and in the middle, preventing vibration and effectively ensuring printing accuracy. Furthermore, the design of screws 39 does not interfere with the maintenance clearance 36.

[0045] In some embodiments, as Figure 3 As shown, the top frame 33 includes a top horizontal frame 331 and a top vertical frame 332. A wiring trough 333 is defined on the top horizontal frame 331 and the top vertical frame 332. The top horizontal frame 331 also has a cable drop opening 334. In this embodiment, cables are routed through the wiring trough 333 and cable drop opening 334 on the east side, fully utilizing the space in the top frame 33 and ensuring uniform cable routing.

[0046] In some embodiments, as Figure 2 As shown, in order to isolate dust, dust covers 30 are further provided on the front, rear and top sides of the printing carriage 3.

[0047] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, while the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
