Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cartons, in particular to a corrugated carton printing device. Background Art

[0002] A corrugated carton is a packaging container made of corrugated cardboard and is commonly used for transporting and storing goods. Corrugated cardboard is composed of a layer of corrugated paper sandwiched between two layers of flat paper, and such a structure endows the carton with excellent compressive performance and buffering capacity.

[0003] As disclosed in the Chinese patent with the publication number CN220661868U, there is disclosed a corrugated carton printing device, including an installation table, a conveying device, a printing device, and a dust removal component. Two groups of dust removal components are fixedly installed on both sides of the upper end surface of the installation table. This corrugated carton printing device has the advantages of good dust removal effect, improved production efficiency, and wide adaptability. When the corrugated carton is conveyed on the conveyor belt, the rotating buttons on the two sliders are loosened counterclockwise, and then the two sliders are slid on the slide rod, driving the positioning block fixed to the slider, the connecting shaft fixed to one side of the positioning block, and the sticky dust tape roll. Finally, the height adjustment of the sticky dust tape roll is completed. When the corrugated carton reaches below the sticky dust tape roll, the sticky dust tape roll is driven to roll above the corrugated carton to remove the dust on the surface of the corrugated carton. Compared with the device in the cited document, this device adds a dust removal component before printing to prevent the problem of unclear patterns in subsequent printing.

[0004] However, in this patent, when the sticky dust tape roll contacts the top surface of the corrugated carton, it is easy to drive the corrugated carton to move under the action of friction, resulting in misalignment of subsequent printed patterns, leading to rework and delaying the production progress. Therefore, improvement is needed. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a corrugated carton printing device to facilitate solving the technical problems mentioned in the above background art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present invention in detail with reference to the drawings.

[0022] Embodiment:

[0023] Refer to Figures 1 to 4, a corrugated cardboard box printing device disclosed by the present utility model includes a chassis 1 and a conveyor belt 2 fixedly connected to the upper half of the chassis 1. The corrugated cardboard box is placed on the top of the conveyor belt 2. Two side plates 3 are fixedly connected to both sides of the top of the chassis 1 near the two sides. Moving plates 4 are arranged on both sides of the top of the chassis 1 where the conveyor belt 2 is located. A plurality of electric push rods 12 are fixedly connected to the side walls of the side plates 3. The output ends of the plurality of electric push rods 12 are fixedly connected to the side walls of the corresponding moving plates 4. A fixing plate 5 is arranged at the lower half of the side of the moving plate 4 close to the conveyor belt 2. An inverted U-shaped shell 6 is arranged at the upper half between the two moving plates 4. A processing member 7 is arranged inside the inverted U-shaped shell 6. Linkage parts 8 are arranged between the inverted U-shaped shell 6 and the two moving plates 4.

[0024] In this embodiment, the inverted U-shaped shell 6 is always in a horizontal state. After the conveyor belt 2 conveys the corrugated cardboard box to the processing position, the plurality of electric push rods 12 work synchronously, so that the two moving plates 4 move towards each other. The moving plates 4 drive the fixing plate 5 to move towards the corrugated cardboard box and drive the inverted U-shaped shell 6 to move downward.

[0025] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 4 shown, the processing member 7 includes two rotating rods 71 arranged inside the inverted U-shaped shell 6. Adhesive tape rolls 72 and printing rollers 73 are fixedly sleeved on the outer circumferential surfaces of the two rotating rods 71 respectively. The bottom of the inverted U-shaped shell 6 is open. The lower halves of the adhesive tape rolls 72 and the printing rollers 73 both extend below the inverted U-shaped shell 6, and the lowest points of the adhesive tape rolls 72 and the printing rollers 73 are at the same height.

[0026] In this embodiment, when both fixing plates 5 contact the side walls of the corrugated cardboard box, the lowest points of the adhesive tape rolls 72 and the printing rollers 73 move to the same height as the top surface of the corrugated cardboard box, and at this time, the adhesive tape rolls 72 and the printing rollers 73 are not directly above the corrugated cardboard box.

[0027] In a further preferred embodiment of the present utility model, as Figure 2 shown, the linkage part 8 includes a slideway 81 opened at the upper half of the side wall of the moving plate 4. A slider 82 is slidably connected in the slideway 81. One side of the slider 82 is hinged with a rotating plate 83. The side of the rotating plate 83 away from the slider 82 is hinged with the side wall of the inverted U-shaped shell 6. A motor 84 is fixedly connected to the inner side wall of the slideway 81. The output end of the motor 84 is drivingly connected with a lead screw 85. The lead screw 85 is in threaded connection with the corresponding slider 82.

[0028] In this embodiment, when the two moving plates 4 move towards each other, they drive the two rotating plates 83 to rotate. The rotating plates 83 drive the inverted U-shaped shell 6 to move downward. The inverted U-shaped shell 6 drives the adhesive tape rolls 72 and the printing rollers 73 to move downward.

[0029] When both fixing plates 5 are in contact with the side wall of the corrugated cardboard box, that is, when the lowest points of the dust sticking tape roll 72 and the printing roller 73 move to the same height as the top surface of the corrugated cardboard box, the two motors 84 work synchronously to drive the two lead screws 85 to rotate. The lead screws 85 drive the sliders 82 to move, the sliders 82 drive the U-shaped housing 6 to move, and the U-shaped housing 6 drives the dust sticking tape roll 72 and the printing roller 73 to move towards the corrugated cardboard box. During this process, the dust sticking tape roll 72 first contacts the top surface of the corrugated cardboard box and rotates under the action of friction to remove dust from the top surface of the corrugated cardboard box. The printing roller 73 then contacts the top surface of the corrugated cardboard box and rotates under the action of friction to print on the top surface of the corrugated cardboard box until both the dust sticking tape roll 72 and the printing roller 73 have passed over the corrugated cardboard box, and the printing of the corrugated cardboard box is completed. The electric push rod 12 contracts, driving the two moving plates 4 to move away from each other, the fixing plates 5 move towards a direction away from the corrugated cardboard box, and the U-shaped housing 6 moves upward. At this time, the motor 84 rotates in reverse to send the U-shaped housing 6 back to the initial position, and the conveyor belt 2 works to send away the printed corrugated cardboard box.

[0030] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 3 shown, two first lead screws 9 are threadedly connected to the upper half of the U-shaped housing 6. The bottom ends of the first lead screws 9 are rotatably connected to sliding blocks 10. The sliding blocks 10 are in contact with the inner side wall of the U-shaped housing 6, and the opposite ends of the rotating rod 71 are respectively rotatably connected to the two sliding blocks 10.

[0031] In this embodiment, when processing a corrugated cardboard box at another height, the staff simultaneously rotates the two first lead screws 9 to drive the two sliding blocks 10 to move vertically, thereby driving the dust sticking tape roll 72 and the printing roller 73 to move vertically, changing the initial height of the dust sticking tape roll 72 and the printing roller 73 to adapt to corrugated cardboard boxes of different heights.

[0032] In a further preferred embodiment of the present utility model, as Figure 1 shown, two second lead screws 11 are threadedly inserted through the lower half of one side of the moving plate 4. One ends of the two second lead screws 11 close to the conveyor belt 2 are respectively rotatably connected to the corresponding fixing plates 5.

[0033] In this embodiment, when processing a corrugated cardboard box with another width, the staff simultaneously rotates the two second lead screws 11 to drive the fixing plates 5 to move horizontally, changing the initial position of the fixing plates 5 to adapt to corrugated cardboard boxes of different widths.

[0034] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
