Description

Technical Field

[0001] This utility model belongs to the field of carton printing technology and relates to a packaging carton printing device. Background Technology

[0002] Printing is a technology that uses processes such as plate making, inking, and pressing to transfer ink to the surface of materials such as cardboard, textiles, plastics, leather, PVC, and PC, to mass-produce the content of the original manuscript, including text, pictures, photographs, and anti-counterfeiting materials.

[0003] As the most widely used packaging product, environmentally friendly cardboard boxes come in various forms, including corrugated cardboard boxes and single-layer cardboard boxes, depending on the materials used. They are available in various sizes and models and serve as wrapping materials for goods or as protective outer layers for items. The volume of the cardboard box varies depending on the size of the goods. Cardboard boxes usually have some warning signs printed on them to remind users and protect the contents from damage. However, many cardboard boxes are made of rough-surfaced cardboard. During the processing of this type of cardboard, there are excess fibers and dust on the surface. Traditional printing equipment is not very effective at removing these excess impurities, which can easily affect the adhesion of ink during the printing process, causing the ink to easily peel off.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1-4 As shown, this utility model is a packaging carton printing device, including two supports 1, at least two rollers 11 between the supports 1, and two connecting rods 2 on each support 1. One end of the connecting rods 2 is provided with a support plate 21. A motor 22 is provided in the middle of the upper end of the support plate 21. The output shaft of the motor 22 extends out of the support plate 21, and a brush 23 is provided on the outside of the output shaft of the motor 22. With the setting of the brush 23, the brush 23 rotates under the drive of the motor 22, and brushes the surface of the packaging carton on the rollers 11, so that the packaging carton is clean and tidy, thereby improving the printing effect.

[0023] A printing support 4 is provided on the support 1. A rotating shaft 41 is rotatably provided inside the printing support 4. A printing roller 42 is provided on the rotating shaft 41. One end of the rotating shaft 41 extends out of the support 1 and is externally connected to a drive motor to drive the printing roller 42 to rotate and print on the surface-cleaned packaging carton. Under the rotation of the external drive motor, the rotating shaft 41 is driven to rotate, and the printing roller 42 is driven to rotate, and the surface-cleaned packaging carton is printed.

[0024] When motor 22 starts, it drives brush 23 to rotate quickly and evenly, ensuring that brush 23 can fully cover the surface of the packaging carton on roller 11, thus guaranteeing the uniformity and consistency of the cleaning process.

[0025] Driven by the motor 22, the brush 23 brushes the surface of the packaging carton on the roller 11 at an appropriate speed and force, and removes excess fibers, debris and dust from the surface of the packaging carton, thereby ensuring the cleanliness of the carton surface.

[0026] This cleaning process makes the surface of the packaging carton clean and tidy, laying a solid foundation for the subsequent printing process. Because the cleanliness of the carton surface is significantly improved, the adhesion and uniformity of the ink during printing are also enhanced, thereby greatly improving the printing effect.

[0027] In summary, by setting up the brush 23 and driving the motor 22, the brush 23 removes stains and impurities from the surface of the packaging carton, thereby ensuring the cleanliness of the carton surface and improving printing efficiency.

[0028] Preferably, at least two brushes 23 are provided at equal intervals on the outer side of the output shaft of the motor 22. The brushes 23 are connected to the output shaft by bolts so as to facilitate the disassembly and replacement of the brushes 23.

[0029] Preferably, the support 1 is provided with a U-shaped rod 37, the U-shaped rod 37 is provided with two pull rods 36, and the pull rods 36 are provided with a push plate 35. The push plate 35 is triangular in shape, and the corner that contacts the carton is made of rubber. The use of rubber material protects the surface of the packaging carton. The push plate 35 allows the surface of the packaging carton to be cleaned a second time when it is transported on the rollers 11, making the cleaning cleaner and tidier.

[0030] In this embodiment, the bracket 1 is provided with two springs 38, and the upper end of the springs 38 is provided with a limiting plate 32. The limiting plate 32 is provided with a through groove 33, and the push plate 35 is located in the through groove 33.

[0031] The bracket 1 is also equipped with a screw 3, the upper end of which extends into a limiting plate 32. A nut 31 is screwed onto the outer side of the screw 3, and the nut 31 is located below the limiting plate 32. By rotating the nut 31, the distance between the limiting plate 32 and the bracket 1 can be adjusted, which facilitates the use of packaging cartons of different sizes. The spring 38 ensures that the push plate 35 can always maintain contact with the surface of the packaging carton.

[0032] The left and right ends of the limiting plate 32 are bent upwards, and at least two balls are provided on the side of the limiting plate 32 near the bracket 1. By bending the two ends of the limiting plate 32 upwards to allow the packaging carton to pass through, the balls are provided to reduce the friction between the limiting plate 32 and the packaging carton, thereby facilitating the movement of the packaging carton.

[0033] In this embodiment, a baffle 34 is provided on the limiting plate 32. The baffle 34 is U-shaped and has a rectangular hole. Half of the opening of the baffle 34 is located above the through groove 33. A suction fan is connected to the rectangular hole to remove the impurities scraped off the push plate 35, so as to ensure the cleanliness of the surface of the packaging carton and facilitate subsequent printing.

[0034] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
