[0016] The beneficial effects of the present invention are:

[0017] (1) The printing carriage is driven simultaneously by the linear motor of the double beam and the mover plate. Under the premise that there are more than 100 nozzles, the mover plate can provide a sufficiently large driving force on the one hand, and the two mover plates are controlled in parallel on the other hand, which can ensure that the two mover plates are driven synchronously and the driving force remains synchronized. At the same time, precise control can be achieved, effectively ensuring printing stability and accuracy.

[0018] (2) The movers on the mover plate adopt a multi-motor structure, which can provide a greater driving thrust to the printing carriage; at the same time, the head distance L1 of adjacent mover plates is an integer multiple of the stator plate length L2, so that the thrust directions provided by the movers are consistent, which can overcome the opposite thrusts generated between the movers;

[0019] (3) Since the weight of the printing carriage is already very large, a number of weight-reducing grooves are provided on the mover plate to avoid further increasing the weight of the printing carriage and achieve the purpose of weight reduction.

[0020] (4) The linear motor is arranged above the crossbeam. The linear motor is located above the crossbeam, has a simple structure, and can easily ensure installation accuracy and increase thrust. At the same time, the top and side of the crossbeam are provided with a first slide rail. The addition of the first slide rail on the top and side increases the force on the slide rail, which can increase the stability of the print carriage during operation under the huge weight of the print carriage. More specifically, the first slide rail located on the top of the crossbeam can increase the bearing capacity, while the first slide rail located on the side can increase the operation accuracy.

[0021] (5) A maintenance escape is formed below the first trolley mounting frame. The design of the maintenance escape can facilitate maintenance personnel to repair the interior of the printing trolley from the maintenance escape. Furthermore, the middle part of the trolley chassis is connected to the side frame near the top through a screw, and then the screw is rotated to lock it. In this way, the middle of the trolley chassis is given a pulling force by the side frame through the screw. When the printing trolley is running, the trolley chassis is supported by pulling force on both sides and the middle part to prevent shaking, thereby effectively ensuring printing accuracy. At the same time, the design of the screw will not affect the maintenance escape.

[0022] (6) The first crossbeam and the second crossbeam are respectively arranged above the adjustment mechanism. During installation, the position of the crossbeam can be adjusted by the adjustment mechanism to ensure that the first crossbeam and the second crossbeam are parallel and aligned, thereby effectively ensuring the printing accuracy. At the same time, the entire frame is easy to install and disassemble.

[0023] (7) After the cleaning device cleans the scraper of the nozzle, the water in the cleaning chamber is connected through the first guide tube and the second guide tube, and the water is transported to the moisturizing box through the water solenoid valve for secondary recycling to moisturize, thereby reducing water waste and reducing printing costs.

[0024] (8) The printing medium passes through the upper cloth roller group, the first tension roller group, the second tension roller, the third tension roller, the expansion roller, the fourth tension roller, the fifth tension roller, the sixth tension roller group and the cloth feed roller in sequence, and is transported to the bottom of the printing carriage for printing. The expansion roller enables the printing medium to expand to both sides during printing, and a separation groove is provided in the middle of the expansion roller, so that both sides of the separation groove can expand separately. The medium can be divided into two groups on both sides of the separation groove, and two groups of different media with smaller widths can be transported and printed at one time, reducing waste, improving printing efficiency, and various printings are not affected.

The movers 265 can be energized to generate a magnetic induction effect, and the distance between the heads of two adjacent stators is L1; wherein L1 is an integer multiple of L2.

[0046] Specifically, 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.

A plurality of weight-reducing grooves 266 are provided on one side of the movable vertical plate 262; since the weight of the printing carriage 3 is already very large, a plurality of weight-reducing grooves 266 are provided on the movable plate 26 to avoid further increasing the weight of the printing carriage 3 and achieve the purpose of weight reduction. A second slide rail 267 is provided on the other side of the movable vertical plate 262, and a second slider 268 is slidably arranged on the second slide rail 267, and the second slider 268 is connected to the printing carriage 3.
