[0020] In this embodiment, a sensor 5 for sensing the position of the slider 4 is installed on the side panel of the frame 1. The sensor 5 is a blocking sensor. The slider 4 is provided with a sensor baffle 401 that cooperates with the sensor 5. The position of the slider 4 can be determined by the positional relationship between the sensor baffle 401 and the sensor 5, and then the lifting and lowering of the carriage assembly 2 can be accurately controlled by accurately controlling the movement of the slider 4.

[0021] In this embodiment, the driving mechanism includes a rotating shaft 602 installed between the side plates on both sides of the frame 1, and a final gear 604 located above the slider 4 and transmission-connected to the rotating shaft 602 is installed on the side plate of the frame 1, and a rack 404 meshing with the final gear 604 is provided on the upper side of the slider 4.

[0022] In this embodiment, the driving mechanism also includes a motor 7 and a reduction gear system 603 installed on one side panel of the frame 1. The motor 7 is connected to the rotating shaft 602 through the reduction gear system 603, and the rotating shaft 602 is connected to the final gear 604 through a driven gear system 601 installed on the side panel of the frame 1. The gear train 6 is composed of a final gear 604, a reduction gear train 603, a rotating shaft 602 and a driven gear train 601. The slider 4 is meshed with the final gear 604 through the rack 404 arranged thereon. The rotation of the motor 7 drives the reduction gear train 603 to move, and drives the driven gear trains 601 installed on both sides of the frame 1 to move via the rotating shaft 602. The driven gear train 601 then drives the slider 4 to move horizontally through the final gear 604. The left and right sides of the frame 1 are both provided with a motion mechanism composed of a driven gear train 601 and a slider 4. The motion mechanisms on both sides have the same structure, and the motion mechanisms on both sides are synchronized through the rotating shaft 602 to achieve synchronous and stable lifting of the carriage assembly 2 on the left and right sides.

[0023] In this embodiment, the driven gear train 601 is composed of two meshing gears, one of which is also meshed with the final gear 604, and the other gear is installed at the end of the rotating shaft 602; the reduction gear train 603 is composed of a plurality of gears meshing in sequence, and the last gear is installed on the rotating shaft 602; the driven gear train 601, the final gear 604 and the slider 4 are installed on the outer side of the side plate of the frame 1, and the motor 7 and the reduction gear train 603 are installed on the inner side of the side plate on one side of the frame 1.

[0024] In this embodiment, the lifting guide rail 402 is a stepped guide rail and two adjacent step surfaces are transitioned by an inclined surface, and the inclined surface and the step surface are transitioned by an arc surface, ensuring that the carriage guide shaft 3 can be raised and lowered smoothly and gently, and has a wide adaptability to the thickness of the printing medium.

[0025] In this embodiment, the side panel of the frame 1 has two slider rails 103 arranged in the horizontal front-to-back direction, one above and one below. The slider 4 is provided with a guide column 403 that cooperates with the slider rail 103. The slider 4 realizes horizontal movement of a fixed track through the sliding cooperation with the slider rail 103 on the frame 1 through the guide column 403.

[0026] In this embodiment, a carriage guide rail 101 located above the carriage assembly 2 is connected between the side panels of the frame 1, and a sliding bearing that slides with the carriage guide rail 101 is provided at the upper end of the carriage assembly 2; a guide shaft hole 202 that slides with the carriage guide shaft 3 is provided on the carriage assembly 2; the carriage assembly 2 equipped with a print head 201 is connected to the carriage guide shaft 3 through the guide shaft hole 202 provided thereon, and is restricted by the carriage guide rail 101 on the frame 1, and can only move horizontally along the carriage guide shaft 3 or move vertically along the carriage guide rail 101 as the carriage guide shaft 3 is lifted.

[0027] A working method of a printing carriage device adapted to ultra-thick media as described above, when the printing medium is transported to the designated printing area, the carriage assembly 2 is first lifted and lowered, and then the printing task is executed. Specifically, the system first determines the required lifting height of the carriage assembly 2 corresponding to the current printing medium, and then controls the movement of the motor 7 to accurately control the left and right sliders 4 to move from the initial position to the target position, and controls the lifting and lowering of the carriage guide shaft 3 by means of the lifting guide rail 402 on the slider 4, so that the carriage assembly 2 is lifted and lowered, and the printing task is started when the carriage assembly 2 completes the lifting and lowering action and reaches the target height.

[0028] In this embodiment, in the standby state, the height position of the carriage assembly 2 needs to be reset. At this time, the rotation of the motor 7 drives the driven gear system 601 on the left and right sides of the frame 1 to move through the reduction gear system 603 and the rotating shaft 602, and then the final gear 604 cooperates with the rack 404 on the slider 4 to convert the rotation of the motor 7 into the horizontal forward and backward movement of the slider 4. By judging the direction of the motor 7 and the positional relationship between the sensor 5 and the sensor baffle 401, the position of the slider 4 can be accurately located, thereby controlling the lifting and lowering of the carriage assembly 2 back to the predetermined initial position.
