[0037] like Figure 1-6 As shown, this embodiment proposes a packaging cardboard printing device, including a support 1 and a cross-shaped plate 2 fixedly installed on the top of the support 1, and also including...

[0043] Controller 8 is fixedly installed on the outer wall of one of the U-shaped connecting plates 3.
[0044] like Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the square tracking component 5 further includes a drive rotating sleeve 501 mounted on the top plate 4, a slide rod 502 slidably connected to the center of the drive rotating sleeve 501, a connector 503 fixedly mounted on one end of the slide rod 502, a spring 504 fixedly mounted between the drive rotating sleeve 501 and the connector 503 and sleeved on the outside of the slide rod 502, a slider 505 rotatably connected to the connector 503, fixing blocks 506 fixedly and symmetrically distributed at the bottom of the top plate 4, a crossbar 507 fixedly disposed between the two sets of fixing blocks 506, a slide cylinder 508 slidably connected to the outer wall of the crossbar 507, and a limiting rod 509 fixedly mounted in the horizontal direction of the slide cylinder 508. The slider 505 and the limiting rod 509 are slidably connected, which can form a stable square trajectory cycle.
[0045] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the reciprocating printing assembly 6 further includes an ink reservoir 601 fixedly installed at the bottom of the slider 505, a fixing plate 602 fixedly installed on the outer wall of the ink reservoir 601, a mounting frame 603 fixedly installed at one end of the fixing plate 602 away from the ink reservoir 601, a drive turntable 604 installed at the center of the side wall of the mounting frame 603, a guide rod 605 fixedly installed on the outer wall of the drive turntable 604, a groove opened at the center of the mounting frame 603, a reciprocating plate 606 slidably connected to the inner wall of the groove, a limiting frame 607 fixedly installed in the middle section of the reciprocating plate 606, and a printing part 608 fixedly installed at the bottom of the reciprocating plate 606. The guide rod 605 is slidably connected to the inner wall of the limiting frame 607, which enables the printing part 608 to move up and down to complete the printing action.
[0046] like Figure 2 , Figure 3 and Figure 6As shown, in a preferred embodiment, based on the above method, the proximity switch assembly 7 further includes an L-shaped connecting plate 701 fixedly and symmetrically installed on the outer wall of the limiting frame 607, a fixing ring 702 fixedly installed on the vertical section of the two sets of L-shaped connecting plates 701, sensor probes 703 fixedly and evenly distributed at the bottom of the fixing rings 702, mounting grooves evenly opened on the inner wall of the cross-shaped plate 2, and iron pieces 704 fixedly installed on the inner wall of the mounting groove. Any iron piece 704 is on the same vertical line as one of the sets of sensor probes 703, which can detect the position signal of the printing section 608 in real time and realize the precise positioning of the printing surface switching.
[0047] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, an ink inlet pipe 9 is fixedly installed on the top of the ink storage box 601, and a valve is provided on the ink inlet pipe 9. An ink supply pump 10 is fixedly installed on the bottom of the ink storage box 601. An ink supply hose 11 is connected between the outlet of the ink supply pump 10 and the printing section 608. The ink supply pump 10 supplies ink to the printing section 608 through the ink supply hose 11.
[0048] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the controller 8 is further connected to the sensor probe 703 of the proximity switch assembly 7 via a circuit, and the controller 8 is connected to the drive turntable 604 and the ink supply pump 10 of the reciprocating printing assembly 6 via a circuit. By controlling the start and stop of the drive turntable 604 and the start and stop of the ink supply pump 10 through the controller 8, the precise positioning of the printing surface switching and the synchronous control of the ink volume are realized, avoiding misalignment or ink overflow, and ensuring the accuracy and consistency of the printed pattern.
[0049] Specifically, when this packaging cardboard printing device is in operation: first, the unfolded packaging cardboard is placed in the center of the cross-shaped plate 2 and fixed with clamps;
[0050] The drive rotating sleeve 501 rotates under the command of the controller 8, causing the slide bar 502 to slide inside the drive rotating sleeve 501. At the same time, the spring 504 provides elastic restoring force to ensure that the slide bar 502 can automatically return to its position after moving, forming a stable square trajectory cycle. The limit rod 509 cooperates with the slider 505 to constrain the slide cylinder 508 to move horizontally along the cross bar 507, ensuring that the printing path is a precise square.
[0051] When the square tracking component (5) moves the printing section (608) to one side of the carton, the sensor probe (703) detects the corresponding iron piece (704) on the inner wall of the cross-shaped plate (2), triggering a signal to the controller (8). The controller (8) receives the signal in real time and pauses the rotation of the drive rotating sleeve (501) to lock the position of the printing section (608). It then starts the drive turntable 604 to rotate and drives the limit frame 607 to reciprocate in the chute through the guide rod 605. At the same time, the controller (8) starts the ink supply pump 10, which supplies ink to the printing section 608 synchronously and quantitatively through the ink supply hose 11, causing the printing section 608 to move up and down to complete the printing action.
[0052] After the printing detection unit (608) is reset to the high position, the square tracking component (5) is restarted and turns to the next side. The sensor probe (703) is triggered again, and the above printing action is repeated in a loop to complete the printing of the four sides of the carton in sequence. The controller (8) records the number of printed sides in real time. When the printing of the four sides is completed, the drive rotating sleeve (501) and drive turntable (604) are automatically stopped, and the equipment enters the standby state. Finally, the operator removes the printed packaging cardboard and replaces the packaging cardboard to be printed.
[0053] All technical features in this embodiment can be freely combined according to actual needs.
[0054] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
