[0033] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0034] Embodiment 1:

[0035] like Figure 1-6 As shown, a packaging box surface coding device includes a conveying component 2 supported on the ground by supporting legs 1.

[0036] The top of the conveying component 2 is provided with a coding component 3 and a material discharge component 4. The conveying component 2 includes two symmetrically arranged fixed plates 5. The two fixed plates 5 are rotatably connected to two conveying rollers 6 on opposite sides through a rotating shaft 7, and the outer walls of the two conveying rollers 6 are driven and matched with the same conveyor belt. One end of one of the conveying rollers 6 is fixedly connected to a motor 19 through a coupling, and the motor 19 is fixed to the outer wall of the conveying component 2 by bolts. A material receiving box 8 is provided at the bottom of the fixed plate 5.

[0037] The top of the conveyor belt is provided with a plurality of groups of material taking components 9 for taking materials, the material taking components 9 include a box body 13 and a plurality of hollow cylinders 15, the box body 13 is fixedly connected to the outer wall of the conveyor belt, the hollow cylinders 15 are slidably matched to the inner wall of the box body 13, and the tops of all the hollow cylinders 15 are fixedly connected and connected to suction cups 14.

[0038] Start the motor 19 to drive one of the conveyor rollers 6 and the rotating shaft 7 to rotate, and with the cooperation of the conveyor belt and another set of conveyor rollers 6 and the rotating shaft 7, drive the box body 13, the suction cup 14 and the hollow cylinder 15 to reach the blanking component 4, and use the suction cup 14 to pull out a packaging box at the bottom of the blanking component 4 and transport it to the coding component 3 for coding.

[0039] The device is provided with multiple groups of material picking components 9, and uses the conveying component 2 to transport the box body 13, the suction cup 14 and the hollow cylinder 15 in the material picking component 9 to the material discharging component 4. A packaging box located at the bottom of the material discharging component 4 can be drawn out and continued to be transported to the coding component 3 for coding, so that the packaging boxes can be transported continuously and equidistantly, ensuring the consistency of the coding effect while improving the coding efficiency.

[0040] like Figure 3 and Figure 4 As shown, the inner wall of the hollow cylinder 15 is slidably fitted with a piston rod 16, one end of the piston rod 16 passes through the hollow cylinder 15 and is fixedly connected to a second slide bar 18, and the outer wall of the bottom of the hollow cylinder 15 is fixedly connected to a first slide bar 17, and both the first slide bar 17 and the second slide bar 18 are slidably fitted with the inner wall of the box body 13.

[0041] A guide groove 10 and a guide groove 2 11 are provided on opposite sides of the two fixed plates 5, and both ends of the slide bar 17 and the slide bar 2 18 are respectively rollingly matched with the guide groove 2 11 and the guide groove 1 10 through the guide wheel 12. The guide groove 1 10 is provided with an inclined groove 1 10a and an inclined groove 2 10b, and the guide groove 2 11 is provided with an inclined groove 3 11a and an inclined groove 4 11b. The inclinations of the inclined groove 1 10a and the inclined groove 2 10b are greater than the inclinations of the inclined groove 3 11a and the inclined groove 4 11b.

[0042] The guide wheel 12 is used to drive the box body 13 and all its internal components to move along the path provided by the guide groove 10 and the guide groove 2 11. When reaching the inclined groove 10a and the inclined groove 3 11a, the box body 13 is located at the bottom of the unloading component 4, and the slide bar 17 and the slide bar 2 18 drive the hollow cylinder 15 and the piston rod 16 to move to the outside of the box body 13 at the same time, so that the top of the suction cup 14 fits with the bottom of the packaging box. Since the inclination of the inclined groove 3 11a is less than the inclination of the inclined groove 10a, the movement speed of the suction cup 14 and the hollow cylinder 15 is less than the movement speed of the piston rod 16, so that the hollow cylinder 15 is moved to the outside of the box body 13. Negative pressure is generated in the cylinder 15, so that the suction cup 14 can absorb the packaging box and move it with the conveyor belt to the coding component 3 for coding. After the coding is completed, when it continues to move with the conveyor belt to the material receiving box 8, the slide bar 17 and the slide bar 2 18 drive the hollow cylinder 15 and the piston rod 16 to move toward the inside of the box body 13 at the same time. Since the inclination of the inclined groove 2 10b is greater than the inclination of the inclined groove 4 11b, the movement speed of the suction cup 14 and the hollow cylinder 15 is still lower than the movement speed of the piston rod 16. At this time, the negative pressure in the hollow cylinder 15 disappears, and the packaging box after coding falls into the material receiving box 8 for unified collection.

[0043] The device is provided with a guide groove 10 and a guide groove 2 11, and utilizes the structural features of the guide groove 10 and the guide groove 2 11 to cause the suction cup 14, the hollow cylinder 15 and the piston rod 16 to undergo different displacement changes accordingly, so that the hollow cylinder 15 generates or eliminates negative pressure, thereby replacing the work of the air pump, reducing the layout of the power source and the setting of the pipeline, and making the device structure more compact.

[0044] like Figure 5 and Figure 6 As shown, the inkjet coding assembly 3 includes a guide rod 21, a screw rod 22 and a slider 2324. Two symmetrically arranged support plates 20 are fixed to the top of the fixed plate 5 by bolts. The guide rod 21 is fixedly connected to the opposite side of the support plate 20, and the screw rod 22 is rotatably connected to the opposite side of the support plate 20. One end of the screw rod 22 is fixedly connected to a motor 25 through a coupling, and the motor 25 is fixedly connected to the outer wall of the support plate 20 by bolts.

[0045] The slider 23 is slidably matched with the outer wall of the guide rod 21 and is connected to the outer wall of the screw rod 22 through threads. An inkjet printer 24 is fixedly installed at the bottom of the slider 23.

[0046] The second starting motor 25 drives the screw rod 22 to rotate, and the slider 23 moves horizontally under the guidance of the guide rod 21, so that the spraying position can be changed as needed.

[0047] An infrared detector 26 is also installed on the opposite side of the two support plates 20, and the inkjet printer 24 and the infrared detector 26 are both electrically connected to a controller.

[0048] When the packaging box moves to the infrared radiation detector 26, the infrared radiation of the infrared radiation detector 26 is blocked. At this time, the infrared radiation detector 26 transmits a signal to the controller, and the controller starts the inkjet printer 24 to perform the inkjet operation.

[0049] Embodiment 2:

[0050] A packaging box surface coding device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 7 As shown:

[0051] The unloading assembly 4 includes a storage box 27, a limiting plate 28 and a limiting roller 30. The storage box 27 is fixed to the top of the fixing plate 5 by bolts. The limiting plate 28 is slidably fitted on the inner wall of the storage box 27, and the inner wall at the bottom of the storage box 27 is fixedly connected with a chain of symmetrically arranged load-bearing plates 29.

[0052] The inner wall at the bottom of the limit plate 28 is rotatably connected to a limit roller 30 , the inner wall at the top of the storage box 27 is rotatably connected to a threaded rod 31 , the top of the threaded rod 31 is fixedly connected to a knob 32 , and the bottom of the threaded rod 31 is rotatably connected to the inner wall of the limit plate 28 .

[0053] The knob 32 is turned to drive the threaded rod 31 to rotate, so as to adjust the height of the limiting plate 28 and the distance between the carrying plate 29 and the limiting roller 30, so that only one packaging box is allowed to pass between the carrying plate 29 and the limiting roller 30 at a time.

[0054] Working principle: When the device is in use, the packaging boxes that need to be coded are first folded and neatly stacked in the storage box 27, and the supporting plate 29 is used to provide support for the packaging boxes. Then, the knob 32 is turned to drive the threaded rod 31 to rotate, which can change the height of the limit plate 28, thereby changing the distance between the supporting plate 29 and the limit roller 30, so that only a single packaging box is allowed to pass through at a time, and then the motor 19 is started to drive one of the conveying rollers 6 and the rotating shaft 7 to rotate, and the cooperation of the conveyor belt and the other conveying roller 6 and the rotating shaft 7 drives multiple box bodies 13 to move simultaneously, and the guide wheel 12 moves along the path provided by the guide groove 10 and the guide groove 2 11. When the box body 13 moves to the bottom of the storage box 27, under the guidance of the guide groove 10 and the guide groove 2 11, the slide bar 17 and the slide bar 2 18 drive the hollow cylinder 15 and the piston rod 16 to move to the outside of the box body 13 at the same time, so that the top of the suction cup 14 fits the bottom of the packaging box. Since the inclination of the chute three 11a is less than that of the chute one 10a, the moving speed of the suction cup 14 and the hollow cylinder 15 is less than the moving speed of the piston rod 16, so that negative pressure is generated in the hollow cylinder 15, so that the suction cup 14 can adsorb the packaging box and transport the packaging box to the coding component 3. When the packaging box reaches between the infrared radiation detectors 26, the infrared radiation detectors 26 detect that the infrared rays are blocked and transmit the signal to the controller. The controller starts the inkjet printer 24 to code the packaging box. Then, when the coded packaging box is transported to the receiving box 8, the slide bar 17 and the slide bar 2 18 drive the hollow cylinder 15 and the piston rod 16 to move toward the inside of the box body 13 at the same time. Since the inclination of the chute two 10b is greater than that of the chute four 11b, the moving speed of the suction cup 14 and the hollow cylinder 15 is still less than the moving speed of the piston rod 16. At this time, the negative pressure in the hollow cylinder 15 disappears, and the coded packaging box falls into the receiving box 8 for unified collection.

[0055] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
