[0037] It should be noted that the operating principle of the first driving member 61 is as follows: The motor 6141 drives the second synchronous pulley 6142 to rotate. The second synchronous pulley 6142 drives the third synchronous pulley 6151 to rotate through the first synchronous belt 616. The third synchronous pulley 6151 drives the fourth synchronous pulley 617 to rotate. The fourth synchronous pulley 617 drives the cleaning structure 7 to operate through the second synchronous belt 618. The second synchronous pulley 6142 and the third synchronous pulley 6151 respectively drive the third connecting block 614 and the fourth connecting block 615 to rotate, thereby driving the first connecting seat 611 to reciprocate, further driving the second connecting block 613 and the first synchronous pulley 6131 to rotate. The first synchronous pulley 6131 drives the fifth synchronous pulley 6231 to rotate through the fourth synchronous belt 63;

[0038] The fifth synchronous pulley 6231 drives the sixth connecting block 623 to rotate, thereby driving the second connecting seat 621 to reciprocate. The seventh synchronous pulley 625 rotates accordingly. When the seventh synchronous pulley 625 rotates, the eccentric rod 626 rotates around the center of the seventh synchronous pulley 625, thereby driving the marking structure 8 to start operating;

[0039] When connecting seat 1 611 and connecting seat 2 621 make reciprocating motion, they can push the corrugated cardboard box 5 to slide on the L-shaped seat 3 through the partition plate 602, and then transport the corrugated cardboard box 5 from right to left in sequence to the locations of the cleaning structure 7, the printing structure 8, and the drying structure 10, and the cleaning structure 7, the printing structure 8, and the drying structure 10 perform corresponding operations on the corrugated cardboard box 5. In an optional embodiment, the cleaning structure 7 includes a synchronous wheel eight 701 which is transmission-connected to a synchronous wheel four 617 through a synchronous belt two 618, the synchronous wheel eight 701 is fixedly connected to a gear one 702, the gear one 702 is rotatably mounted on a reinforcing plate 4, the gear one 702 is meshingly connected to a gear two 703, a reciprocating screw 704 is fixed to one end of the gear two 703 close to the reinforcing plate 4, the reciprocating screw 704 extends between the two reinforcing plates 4, and the outer wall of the reciprocating screw 704 is threadedly connected to a moving block 705, the moving block 705 slides with a guide rod 707, the guide rod 707 is fixed between the two reinforcing plates 4, a plurality of bristles 706 are fixed to the lower end of the moving block 705, and the bristles 706 are in contact with the upper end surface of the corrugated box 5.

[0040] It should be noted that when the corrugated cardboard box 5 is transported to the bottom of the cleaning structure 7, the synchronous belt 2 618 drives the synchronous wheel 8 701 to rotate, driving the gear 1 702 to engage with the gear 2 703 for transmission; the gear 2 703 drives the reciprocating screw 704 to rotate, so that the moving block 705 reciprocates along the guide rod 707, and the bristles 706 at its lower end sweep the surface of the cardboard box to remove dust or debris, which is conducive to the subsequent printing of labels on the corrugated cardboard box 5.

[0041] In an optional embodiment, the marking structure 8 includes two connecting plates 804, one end of one connecting plate 804 is rotatably connected to the eccentric rod 626 on the synchronous wheel seven 625, and one end of the other connecting plate 804 is rotatably connected to the eccentric rod 626 on the synchronous wheel five 6231. The other ends of the two connecting plates 804 are respectively rotatably connected to the center rod 803 fixed in the middle of the two side plates 802. The two side plates 802 are respectively located on the outer walls of the two reinforcing plates 4, and a marking device 801 is fixed between the two side plates 802. The two reinforcing plates 4 are relatively provided with sliding openings 41 matching the marking device 801.

A sponge stamp 8011 is installed at the lower end of the marking device 801, and the sponge stamp 8011 is connected to the pigment supply structure 9 through a telescopic tube 805.

[0042] It should be noted that when the eccentric rod 626 rotates with the synchronous wheel, it pushes the side plate 802 to swing up and down along the center rod 803 through the connecting plate 804, driving the marking device 801 to move vertically in the sliding opening 41; when the marking device 801 is pressed down, the sponge stamp 8011 contacts the surface of the corrugated box 5 to complete the printing.

[0043] In an alternative embodiment, the pigment supply structure 9 includes a pigment storage tank 901 fixed between two reinforcing plates 4. An outlet 9011 connected to the telescopic tube 805 is provided at the inner bottom of the pigment storage tank 901. A movable plate 902 is arranged above the pigment storage tank 901.

Moreover, reset springs 903 and support rods 904 are fixed to the front and rear sides of the lower end of the movable plate 902. The lower ends of the reset springs 903 are fixedly connected to the upper ends of the reinforcing plates 4, and the lower ends of the support rods 904 are fixedly connected to the upper ends of the side plates 802.

[0044] It should be noted that when the side plate 802 rises, the support rod 904 drives the movable plate 902 to move upward, the reset spring 903 is stretched, the rubber plug 906 is separated from the outlet 9011, and the ink in the pigment storage tank 901 is injected into the sponge stamp 8011 through the telescopic tube 805; when the label printer 801 is pressed down, the movable plate 902 is reset under the action of gravity and the reset spring 903, the rubber plug 906 closes the outlet 9011, and the ink supply stops, so that the effect of intermittent feeding can be achieved.

[0045] In an alternative embodiment, the drying structure 10 includes an electric push rod 1001. The electric push rod 1001 is installed at the upper end of a fixing plate 42. The two ends of the fixing plate 42 are respectively fixedly connected to the two reinforcing plates 4. The telescopic end of the drying structure 10 extends to the lower end of the fixing plate 42 and is fixedly connected to a drying plate 1002. A plurality of drying lamp tubes 1003 are equidistantly installed at the lower end of the drying plate 1002.

[0046] It should be noted that after the corrugated cardboard box 5 is transported below the drying structure 10, the electric push rod 1001 pushes the drying plate 1002 down to an appropriate height, the drying lamp tubes 1003 are powered on and heated, accelerating the curing of the ink and preventing the label from being blurred.

[0047] The above embodiment discloses a corrugated cardboard box label printing device. Among them, the corrugated cardboard box 5 is placed in the placement area of the transport plate 601 (separated by the partition plate 602). The motor 6141 drives the second synchronous pulley 6142 to rotate, drives the third synchronous pulley 6151 to rotate through the first synchronous belt 616, and the fourth synchronous pulley 617 transmits the power to the cleaning structure 7 through the second synchronous belt 618. The first synchronous pulley 6131 is linked with the fifth synchronous pulley 6231 through the fourth synchronous belt 63 to ensure the synchronous movement of both sides of the transport plate 601. The eccentric rod 626 rotates with the seventh synchronous pulley 625 and the fifth synchronous pulley 6231, converting the circular motion into the linear reciprocating motion of the transport plate 601, and pushing the cardboard box 5 to pass through the cleaning, label printing, and drying stations in sequence.

[0048] When the carton 5 is transported under the cleaning structure 7, the second synchronous belt 618 drives the eighth synchronous pulley 701 to rotate, driving the first gear 702 and the second gear 703 to mesh and transmit. The second gear 703 drives the reciprocating screw 704 to rotate, causing the moving block 705 to reciprocate along the guide rod 707. The bristles 706 at its lower end brush the surface of the carton to remove dust or debris, ensuring the printing quality of the label.

[0049] When the eccentric rod 626 rotates with the synchronous pulley, it pushes the side plate 802 to swing up and down along the central rod 803 through the connecting plate 804, driving the label printer 801 to move vertically within the sliding opening 41. When the label printer 801 presses down, the sponge stamp 8011 contacts the surface of the carton to complete the label printing.

[0050] When the side plate 802 rises, the support rod 904 drives the movable plate 902 to move upward, stretching the return spring 903, and the rubber plug 906 disengages from the discharge port 9011. The ink in the pigment storage tank 901 is injected into the sponge stamp 8011 through the telescopic tube 805; when the label printer 801 presses down, the movable plate 902 resets under the action of gravity and the return spring 903, and the rubber plug 906 closes the discharge port 9011 to stop the ink supply, achieving precise ink supply.

[0051] After the carton 5 is transported under the drying structure 10, the electric push rod 1001 pushes the drying plate 1002 down to an appropriate height, and the drying lamp tube 1003 is energized to generate heat, accelerating the curing of the ink and preventing the label from being blurred or falling off.

[0052] In one embodiment, a corrugated carton produced by the above corrugated carton labeling device, wherein a pattern or text is printed on the surface of the corrugated carton 5, and the pattern or text is made of a temperature-changing material or thermosensitive color-changing ink. When the temperature of the corrugated carton 5 exceeds 60 °C, the temperature-changing pattern or text changes from the initial color to orange or red.

[0053] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
