[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-4 The present invention provides an embodiment of an inkjet device for a carton printing machine, comprising a connecting mechanism 1 and a moving mechanism 3. An auxiliary mechanism 2 is fixedly installed at the lower end of the connecting mechanism 1, an inkjet mechanism 4 is fixedly installed at the lower end of the moving mechanism 3, and a conveying mechanism 5 is fixedly installed at the upper end of the connecting mechanism 1.

[0026] Specifically, the connecting mechanism 1 is used to connect and fix the entire inkjet unit to the main body of the carton printing machine, playing the role of supporting and connecting various mechanisms. The auxiliary mechanism 2 provides power and guidance for the movement of the moving mechanism 3 to ensure that the inkjet unit 4 can move accurately to the designated printing position. The moving mechanism 3 can drive the inkjet unit 4 to move flexibly in the horizontal and vertical directions, thereby adapting to the printing needs of different sizes and positions. The inkjet unit 4 is responsible for spraying ink onto the surface of the carton to complete the printing task. The conveying mechanism 5 not only stores and conveys ink, but also stores and conveys cleaning fluid so that the inkjet head 403 can be cleaned and maintained when needed.

[0027] Reference Figure 1 , Figure 2 , Figure 4The connecting mechanism 1 includes a bearing plate 103, with connecting plates 102 fixedly installed on both sides of the upper end of the bearing plate 103. Multiple fixing holes 101 are opened on the upper end of the two connecting plates 102. The auxiliary mechanism 2 includes two first fixing plates 201. A motor 203 is fixedly installed on one side of one of the two first fixing plates 201. A lead screw 202 is fixedly installed at the output end of the motor 203. The side of the lead screw 202 away from the output end of the motor 203 is rotatably connected to the other side of the two first fixing plates 201. The moving mechanism 3 includes a moving seat 301 and a second fixing plate 303. A rotating block 302 is rotatably installed at the lower end of the moving seat 301. An electric telescopic rod 305 is fixedly installed at the middle position of the lower end of the second fixing plate 303. The upper end of the second fixing plate 303 is fixedly connected to the rotating block 302. Fixing bolts 304 are threadedly connected at the four corners of the lower end of the second fixing plate 303.

[0028] Specifically, in the connecting mechanism 1, the bearing plate 103 provides an installation base for other mechanisms. The fixing holes 101 on the connecting plate 102 can be used to securely install the entire device on the printing press with bolts or other connectors. In the auxiliary mechanism 2, the motor 203 drives the lead screw 202 to rotate. The rotation of the lead screw 202 drives the movable seat 301 to move horizontally, thereby realizing the horizontal position adjustment of the inkjet mechanism 4. In the moving mechanism 3, the rotating block 302 and the fixing bolt 304 work together to allow the second fixing plate 303 to rotate at a certain angle to adapt to different printing angle requirements. The electric telescopic rod 305 can control the height of the inkjet mechanism 4 in the vertical direction.

[0029] Reference Figure 2 , Figure 3 The inkjet mechanism 4 includes a third fixed plate 402, with an inkjet head 403 fixedly mounted at the lower end of the third fixed plate 402. The upper end of the third fixed plate 402 is fixedly connected to the output end of the electric telescopic rod 305. A connecting pipe 401 is fixedly mounted on one side of the inkjet head 403, and the side of the connecting pipe 401 away from the inkjet head 403 is fixedly connected to the connecting box 505. The conveying mechanism 5 includes two storage boxes 501 and a connecting box 505. A water pump 502 is fixedly mounted inside each of the two storage boxes 501. Conveying pipes 504 are fixedly mounted on both sides of the connecting box 505. A control valve 506 is fixedly mounted on the outer surface of each of the two conveying pipes 504. A water pipe 503 is fixedly mounted at the output end of each of the two water pumps 502. The side of each water pipe 503 away from the output end of the water pump 502 is fixedly connected to the conveying pipe 504. A water inlet 507 is fixedly mounted at the upper end of each of the two storage boxes 501.

[0030] Specifically, in the inkjet mechanism 4, the third fixing plate 402 is used to install and fix the inkjet head 403. The electric telescopic rod 305 can drive the third fixing plate 402 and the inkjet head 403 to move vertically. The connecting pipe 401 delivers the ink or cleaning fluid in the connecting box 505 to the inkjet head 403. In the conveying mechanism 5, the two storage tanks 501 store ink and cleaning fluid respectively. The corresponding water pump 502 draws ink or cleaning fluid from the storage tanks 501 and delivers it to the connecting box 505 through the water pipe 503 and the conveying pipe 504. The control valve 506 can control the flow rate and switch of the ink or cleaning fluid. The water inlet 507 is used to replenish the corresponding liquids in the storage tanks 501 that store ink and cleaning fluid respectively.

[0031] Working Principle: When printing cartons, the entire inkjet unit is first installed onto the carton printing machine using the connecting plate 102 and fixing hole 101 of the connecting mechanism 1. Then, based on the carton size and printing position requirements, the motor 203 of the auxiliary mechanism 2 is started. The motor 203 drives the lead screw 202 to rotate, causing the moving base 301 to move horizontally, thereby adjusting the inkjet mechanism 4 to a suitable horizontal position. To adjust the angle to suit different printing needs, the fixing bolts 304 at the four corners of the second fixing plate 303 can be loosened first, allowing the rotating block 302 to rotate freely around its connection point with the moving base 301. After rotating the rotating block 302 to a suitable angle according to the actual situation of the printing area, the fixing bolts 304 are tightened to ensure the angle is fixed. Simultaneously, the vertical height of the inkjet head 403 can be adjusted via the electric telescopic rod 305. When printing is required, the water pump 502 corresponding to the ink storage tank 501 is started to supply ink. Ink is extracted and transported to the connecting box 505 via water pipe 503 and delivery pipe 504, and then to the inkjet head 403 via connecting pipe 401. The operator can adjust the ink flow rate through the control valve 506 according to the printing requirements. When the carton is transported to the printing position, the inkjet head 403 sprays ink onto the surface of the carton to complete the printing task. During the printing process, the position and angle of the moving mechanism 3 and the inkjet mechanism 4 can be adjusted at any time according to the actual situation to ensure the printing quality. When the inkjet head 403 needs to be cleaned and maintained, the water pump 502 and control valve 506 corresponding to the ink storage tank 501 are turned off, and the water pump 502 and control valve 506 corresponding to the cleaning fluid storage tank 501 are turned on to deliver the cleaning fluid to the inkjet head 403 for cleaning to prevent the printhead from clogging and ensure the subsequent printing effect. When the ink or cleaning fluid in the storage tank 501 is insufficient, it can be replenished through the corresponding water inlet 507.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
