[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1, with reference to Figure 1-3 The printing section is provided with a printing slotting machine with a full servo plate changing mechanism, comprising a paper feeding section 6, two printing sections 2, a slotting section 4 and a die-cutting section 5 which are arranged on a machine base 1 from right to left;

[0026] In this embodiment, both printing sections 2 are provided with a full-servo plate-changing assembly 3, and two conveyor belts 7 are installed on the machine base 1. The full-servo plate-changing assembly 3 mentioned in this embodiment, as well as the paper feeding section 6, the two printing sections 2, the slotting section 4, and the die-cutting section 5 provided on the machine base 1 from right to left, are all prior art.

[0027] In this embodiment, a turning assembly 8 is provided at the junction of the two conveyor belts 7. The turning assembly 8 includes:

[0028] The turning shaft 9 and two turning plates 10 are rotatably mounted on the machine base 1. The two turning plates 10 are symmetrically fixedly connected to the turning shaft 9. Both turning plates 10 are provided with annularly distributed clamping openings 14.

[0029] A stepper motor 11, a worm 12 and a worm wheel 13. The stepper motor 11 is fixedly mounted on the rear outer wall of the base 1. The worm 12 is fixedly sleeved on the output shaft of the stepper motor 11. The worm wheel 13 is fixedly sleeved on the tilting shaft 9. The worm 12 and the worm wheel 13 are meshed with each other.

[0030] During the specific implementation of this embodiment: one side of the cardboard is printed by a printing unit 2 on the right, and then the printed cardboard is sent to the two clamping openings 14 on the right side of the two turning discs 10 through the conveyor belt 7 on the right. At this time, the worm 12 is driven to rotate by the stepping motor 11, and then the worm gear 13 engaged with the worm 12 drives the two turning discs 10 on the turning shaft 9 to rotate 180 degrees to automatically turn the cardboard over. After the turning is completed, the cardboard will be sent to the printing unit 2 on the left by the conveyor belt 7 on the left for printing on the other side. In this way, the printed cardboard can be automatically turned over to achieve the effect of double-sided printing.

[0031] Example 2, reference Figure 1 and Figure 4-6 This embodiment is optimized based on the embodiment 1. Specifically, a height-adjustable dust removal component is provided in the paper feeding portion 6. The height-adjustable dust removal component includes:

[0032] Two chutes and a vertical screw 15 are sequentially provided in the paper feeding portion 6, and the vertical screw 15 is rotatably installed in one of the chutes;

[0033] An adjusting frame 16 is threadedly connected to the vertical lead screw 15 and is also slidably connected between the two slide grooves;

[0034] Roller frame 17, electrostatic dust removal roller 18, roller frame 17 is fixedly connected to the bottom outer wall of adjustment frame 16, and electrostatic dust removal roller 18 is rotatably installed in roller frame 17;

[0035] The servo drive assembly includes a transmission gear 19 fixedly mounted on the top of the vertical screw 15, a servo motor 20 fixedly mounted on the front outer wall of the base 1, and a drive gear 21 fixedly mounted on the output shaft of the servo motor 20. The drive gear 21 meshes with the transmission gear 19.

[0036] During the specific implementation of this embodiment, the servo motor 20 controls the driving gear 21 to rotate, and then the transmission gear 19 meshing with the driving gear 21 drives the vertical lead screw 15 to rotate. Then, under the limit of the two slide grooves, the adjustment frame 16 threadedly connected to the vertical lead screw 15 drives the electrostatic dust removal roller 18 installed on the roller frame 17 to move downward. In this way, the cardboard will contact the electrostatic dust removal roller 18 during the transportation process. The dust removal effect of the electrostatic dust removal roller 18 can effectively remove the floating dust on the surface of the cardboard, thereby improving the quality of subsequent printing. In addition, the height of the electrostatic dust removal roller 18 can be adjusted to facilitate adaptation to cardboards of different thicknesses.

[0037] The working principle of the utility model is as follows: first, the servo motor 20 controls the driving gear 21 to rotate, and then the transmission gear 19 meshing with the driving gear 21 drives the vertical screw 15 to rotate. Then, under the limit of the two slides, the adjustment frame 16 threadedly connected to the vertical screw 15 drives the electrostatic dust removal roller 18 installed on the roller frame 17 to move downward to adapt to cardboards of different thicknesses;

[0038] Secondly, when the paperboard enters the paper feeding section 6 from the conveyor belt 7 on the right, it will contact the electrostatic dust removal roller 18. The dust removal effect of the electrostatic dust removal roller 18 can effectively remove the dust on the surface of the paperboard, thereby improving the quality of subsequent printing;

[0039] Next, the cardboard conveyed by the paper feeding part 6 will enter the printing part 2 on the right side for printing on one side, and then the printed cardboard will be sent to the two clamping openings 14 on the right side of the two turning discs 10 through the conveyor belt 7 on the right. At this time, the worm 12 is driven to rotate by the stepping motor 11, and then the worm gear 13 engaged with the worm 12 will drive the two turning discs 10 on the turning shaft 9 to rotate 180 degrees to automatically turn the cardboard over. After turning over, the cardboard will be sent to the printing part 2 on the left side by the conveyor belt 7 on the left side for printing on the other side. In this way, the printed cardboard can be automatically turned over to achieve the effect of double-sided printing;

[0040] Finally, the cardboard after double-sided printing will be conveyed by the left conveyor belt 7 and will be processed by the slotting part 4 and the die-cutting part 5 in sequence.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
