It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0027] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0029] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0030] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 4As shown, the dual-carriage inkjet printing device provided by the embodiment of the utility model includes: a beam 1, and trolleys 4 are slidably connected on both sides of the beam 1. The two trolleys 4 slide on both sides of the beam 1 in different directions. The two trolleys 4 move in different directions to print contents in different directions, so as to improve printing efficiency and thus increase production efficiency.

[0032] The driving mechanism 5 includes a driving member 501 and a rotating member 502. The rotating member 502 is mounted on the crossbeam 1 and is fixedly connected to the two trolleys 4. The driving member 501 drives the rotating member 502 to drive the two trolleys 4 to move relatively close to or away from each other. The driving member 501 drives a rotating member 502, so that the rotating member 502 drives the two trolleys 4 to move relatively close to or away from each other. The transmission structure is simple, cost-saving, and the complex transmission structure is simplified, which is convenient for maintenance.

[0033] Specifically, the driving member 501 includes a driving roller 5011, and a plurality of driving rollers 5011 are provided. The number of driving rollers 5011 is not specifically limited here. It is sufficient to provide one or more driving rollers 5011 so that the driving roller 5011 can drive the rotating member 502 to rotate. The surface of the driving roller 5011 is in contact with the inner wall of the rotating member 502. The two ends of the driving roller 5011 are rotatably connected to the first fixed plates 7. One end of the two first fixed plates 7 is fixedly installed on one side of the beam 1. A motor 5012 is installed on one side of the first fixed plate 7. One end of the output shaft of the motor 5012 passes through the first fixed plate 7 and is fixedly connected to one end of the driving roller 5011. The driving roller 5011 is driven by the motor 5012, thereby driving the rotating member 502 to rotate.

[0034] Specifically, a first rack 8 is provided on the surface of the driving roller 5011, and a second rack 9 corresponding to the first rack 8 is provided on the inner surface of the rotating member 502. The first rack 8 is meshed with the second rack 9 and is driven by the friction between the driving roller 5011 and the rotating member 502. Slipping may occur, which may easily affect the driving of the rotating member 502 by the driving roller 5011. Therefore, a first rack 8 is provided on the surface of the driving roller 5011, and a second rack 9 is provided on the inner surface of the rotating member 502. The first rack 8 is meshed with the second rack 9 for transmission, thereby increasing the friction between the two, so that the driving roller 5011 can drive the rotating member 502, and the trolley 4 can move steadily to print the printed matter.

[0035] Preferably, two slide grooves 2 are provided on both sides of the crossbeam 1, and one end of the trolley 4 is slidably connected to the two slide grooves 2, and the trolley 4 is fixedly installed on the rotating member 502. The rotating member 502 is not sufficient to bear the weight of the trolley 4, which will cause the rotating member 502 to be unable to drive the trolley 4 to move. By sliding one end of the trolley 4 into the two slide grooves 2, the weight of the trolley 4 can be shared, making it easier for the rotating member 502 to drive the trolley 4 to move.

[0036] Specifically, the trolley 4 includes a vertical plate 401, a horizontal plate 402 is fixedly installed on the lower surface of the vertical plate 401, and a printer 403 is fixedly installed on the upper surface of the horizontal plate 402. The printer 403 performs inkjet printing on the items to be printed. Four fixed rods 404 are fixedly installed on one side of the vertical plate 401. One end of the four fixed rods 404 is rotatably connected to rollers 405. The four rollers 405 are respectively slidably connected to two slide grooves 2. The vertical plate 401, the horizontal plate 402, the fixed rods 404 and the rollers 405 cooperate with each other to share the weight of the printer 403 to prevent the printer 403 from being too heavy and causing the rotating part 502 to be unable to drive. At the same time, the rollers 405 roll in the slide groove 2 to facilitate the rotating part 502 to bring the printer 403 out for mobile printing.

[0037] Preferably, two second fixing plates 406 are fixedly installed on one side of the vertical plate 401, one end of the rotating member 502 is fixedly installed between the two second fixing plates 406, one end of the two second fixing plates 406 are commonly fixedly connected with a second clamping plate 408, the second clamping plate 408 and the two second fixing plates 406 are both provided with threaded holes 11, and the two threaded holes 11 are threadedly connected with bolts 409, and the second clamping plate 408 cooperates with the two second fixing plates 406 to cover one end of the rotating member 502, and then is threadedly connected to the threaded hole 11 through the bolt 409, and the rotating member (502) is penetrated between the two second fixing plates (406) and the second clamping plate (408), so that the trolley 4 is fixed to the rotating member 502, so that the rotating member 502 can drive the trolley 4 to move when it moves.

[0038] To be more specific, a first clamping plate 407 is fixedly installed between the two second fixed plates 406, and a third rack 10 corresponding to the second rack 9 is fixedly installed on one side of the first clamping plate 407. The third rack 10 is meshed with the second rack 9. The meshing of the third rack 10 with the second rack 9 increases the friction between the rotating member 502 and the vertical plate 401, further strengthening the fixing strength between the rotating member 502 and the vertical plate 401, thereby preventing the rotating member 502 from slipping when driving the trolley 4 to move, thereby affecting inkjet printing.

[0039] Preferably, through holes 6 are provided at both ends of the beam 1, and the two ends of the rotating member 502 are respectively sleeved in the two through holes 6. A rotating wheel 14 is rotatably connected in the two through holes 6. The surface of the rotating wheel 14 is provided with a fourth rack corresponding to the second rack 9, and the second rack 9 is meshed with the fourth rack. The two rotating wheels 14 support the two ends of the rotating member 502, so that the rotating member 502 is sleeved on the beam 1. At the same time, the rotating wheel 14 provides a certain tension to the rotating member 502, which is convenient for the driving roller 5011 to drive the rotating member 502. At the same time, during the rotation of the rotating member 502, the rotating wheel 14 cooperates with the rotating member 502 to rotate.

[0040] Preferably, the two first fixed plates 7 are rotatably connected with a clamping wheel 3, the clamping wheel 3 is in contact with the side wall of the rotating member 502, the clamping wheel 3 and the driving roller 5011 are arranged opposite to each other, the rotating member 502 is clamped by the clamping wheel 3 and the driving roller 5011, and the clamping wheel 3 applies a certain pressure to the rotating member 502 to facilitate the rotating member 502 to rotate when the driving roller 5011 rotates.

[0041] Preferably, two detection plates 12 are fixedly installed on both sides of the beam 1, and the two detection plates 12 are respectively located at the two ends of the slide slot 2. A limit sensor 13 is fixedly installed on one side of the detection plate 12. The limit sensor 13 is arranged opposite to the trolley 4. The limit sensor 13 is connected to the motor 5012. When the rotating part 502 drives the trolley 4 to move, when the trolley 4 approaches the limit sensor 13, the limit sensor 13 cuts off the power to the motor 5012 to prevent collision damage to the trolley 4 due to failure of the motor 5012.
