[0027] Specifically: The braking assembly 4 is used to drive the conveyor belt 3 to rotate through the rotating shaft 2, so as to convey the corrugated cardboard box. The U-shaped bracket 5 is used to fix the clamping assembly 6. The clamping assembly 6 is used to blow air on the surface of the corrugated cardboard box to make the adhered dust fall off. The U-shaped fixing frame 7 is used to fix the negative pressure fan 8. The negative pressure fan 8 is used to draw out the blown dust. The fixing block 10 is used to fix the air pump 11. The air outlets of the two air pump nozzles 12 are respectively inclined towards the two negative pressure fans 8. The control terminal 14 is used to control the servo motor 402, the first electric telescopic rod 604, and the second electric telescopic rod 1302. The printing device body 15 prints on the surface of the corrugated cardboard box. Infrared sensors are installed on both the mounting plate 9 and the bottom of the printing device body 15.

[0028] In one embodiment, the braking assembly 4 includes a motor box 401. The motor box 401 is connected to one side of one end of the U-shaped leg 1. One end of one of the rotating shafts 2 passes through one side of the motor box 401 through a bearing and is connected with a first gear 201. A servo motor 402 is installed at the bottom of the inner cavity of the motor box 401. The output end of the servo motor 402 is connected with a second gear 403. The second gear 403 is meshed and connected with the first gear 201.

[0029] Specifically: When the servo motor 402 works, it drives the rotating shaft 2 to rotate through the meshing connection between the second gear 403 and the first gear 201.

[0030] In one embodiment, the clamping assembly 6 includes a housing 601. The housing 601 is embedded in one end of the U-shaped bracket 5. One side of the inner cavity of the housing 601 is connected with a first I-shaped plate 602. A set of first chutes 603 are opened at both end segments on the inner side of the first I-shaped plate 602.

[0031] Specifically: The first chutes 603 limit the square frame 605.

[0032] In one embodiment, both sides inside the first I-shaped plate 602 are connected with first electric telescopic rods 604. The output ends of the two first electric telescopic rods 604 are both connected with square frames 605. The two square frames 605 are respectively movably embedded in the inner sides of the two sets of first chutes 603. The inner parts of the two square frames 605 are both movably embedded with first rotating shafts 606. An adjusting plate 607 is movably sleeved on the surface of one of the first rotating shafts 606. An adjusting plate 608 is movably sleeved on the surface of the other first rotating shaft 606.

[0033] Specifically: The two first electric telescopic rods 604 respectively push and pull the two square frames 605. The two first rotating shafts 606 are respectively used to connect the adjusting plate 607 and the adjusting plate 608.

[0034] In one embodiment, through holes 6071 are opened on the surface of the adjusting plate 607.

[0035] Specifically, the through hole 6071 is used as the movable embedded adjustment plate two 608.

[0036] In one embodiment, the other ends of the adjustment plate one 607 and the adjustment plate two 608 are connected with a clamping plate one 609. One side of the clamping plate one 609 is connected with an I-shaped plate two 610. A set of sliding grooves two 611 are opened at both ends inside the I-shaped plate two 610. A square frame two 612 is movably embedded inside both sets of sliding grooves two 611. The other ends of the adjustment plate one 607 and the adjustment plate two 608 are respectively embedded inside the two square frames two 612 through a rotating shaft.

A positioning rotating shaft 613 is embedded through the surfaces of the through hole 6071 and the adjustment plate two 608 through a bearing.

[0037] Specifically, the sliding grooves two 611 limit the movement of the square frame two 612. When the two electric telescopic rods one 604 push the two square frames one 605 outwards, the two square frames two 612 move towards both sides of the I-shaped plate two 610 respectively, and the clamping plate one 609 moves towards the inside of the housing 601. When the two electric telescopic rods one 604 pull the two square frames one 605 inwards, the two square frames two 612 both move towards the inside of the I-shaped plate two 610, and the clamping plate one 609 moves towards the outside of the housing 601.

[0038] In one embodiment, an installation groove 1301 is opened on one side of the support leg 13. Two electric telescopic rods two 1302 are connected to one side of the inner cavity of the installation groove 1301. The other ends of the two electric telescopic rods two 1302 are connected with a clamping plate two 1303.

[0039] Specifically, the electric telescopic rod two 1302 pushes and pulls the clamping plate two 1303. The clamping plate two 1303 increases the contact area between the output end of the electric telescopic rod two 1302 and the surface of the corrugated cardboard box, making the clamping and fixing effect better.

[0040] Working principle: The control terminal 14 is electrically connected to the servo motor 402, the first electric telescopic rod 604, the air pump 11, the second electric telescopic rod 1302, the negative pressure fan 8, the mounting plate 9 and the infrared induction sensor at the bottom of the printing device body 15. When using the corrugated cardboard box for printing, place the corrugated cardboard box on the surface of the conveyor belt 3, and operate the control terminal 14 to start the servo motor 402, the first electric telescopic rod 604, the air pump 11, the second electric telescopic rod 1302, the negative pressure fan 8, the mounting plate 9 and the infrared induction sensor at the bottom of the printing device body 15. When the infrared induction sensor at the bottom of the mounting plate 9 detects that the corrugated cardboard box is conveyed to the bottom of the fixed block 10, the servo motor 402 stops working, and the control terminal 14 controls the two first clamping plates 609 to clamp and fix the corrugated cardboard box. The control terminal 14 controls the two air pumps 11 to work in sequence to blow the surface of the corrugated cardboard box, and the blown dust is blown to both sides by the two negative pressure fans 8. Through such a setting, it is avoided that dust adheres to the surface of the corrugated cardboard box and affects the printing quality. After the blowing is completed, then the control terminal 14 controls the two first electric telescopic rods 604 to push the two first square frames 605 outwards, and the two second square frames 612 move to both sides of the second I-shaped plate 610 respectively, and the first clamping plate 609 moves towards the inside of the housing 601 to release the clamping of the corrugated cardboard box. Then, the servo motor 402 continues to work, and the conveyor belt 3 conveys the corrugated cardboard box again. When the infrared induction sensor at the bottom of the printing device body 15 detects that the corrugated cardboard box is conveyed to the bottom of the printing device body 15, the servo motor 402 stops working, and the control terminal 14 controls the second electric telescopic rod 1302 to push out the second clamping plate 1303 to clamp and fix the corrugated cardboard box. Then, the printing device body 15 prints on the surface of the corrugated cardboard box. Through such a setting, the corrugated cardboard box is clamped and fixed during printing to avoid the movement of the corrugated cardboard box during printing and affecting the printing quality.

[0041] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms.
