Description

Technical Field

[0001] This utility model relates to the technical field of packaging printing, and in particular to a QR code inkjet printing device and an inline gravure inkjet printing device. Background Technology

[0002] In the tobacco industry, the packaging printing of high-end cigarette products has extremely stringent quality requirements. Their labels or boxes not only need to use gravure printing to achieve exquisite fixed patterns such as large-area spot colors and gold foil backgrounds, but also often require the printing of variable information, such as QR codes, anti-counterfeiting codes, production dates, and batch numbers, in specific locations to achieve product traceability and anti-counterfeiting marketing functions. Therefore, integrating inkjet printing equipment with gravure printing production lines to form a highly efficient integrated production solution has become the mainstream trend in the industry.

[0003] Currently, there are relevant technical solutions dedicated to realizing the inline production of gravure printing machines and inkjet printing equipment. For example, the utility model patent with authorization announcement number CN220349284U discloses an inline inkjet printing device for gravure printing machines. This device includes a gravure printing machine, an inkjet printer, a winding machine, and a die-cutting machine. The gravure printing machine and the winding machine are connected by a bridge. The inkjet printer is located below the bridge. The guide rollers on the bridge feed the paper printed by the gravure printing machine into the inkjet printer. Depending on the subsequent process requirements, the paper can be fed into the winding machine via the left paper feed roller or into the die-cutting machine via the right paper feed roller.

[0004] However, such devices still have limitations in practical applications. The device fixes the inkjet printer under the bridge, and the position of its inkjet head is static. Since different batches of cigarette packs in the tobacco industry have different printing requirements, the optimal printing distance and position for each cigarette pack are different. The inkjet printer in the above device lacks the necessary adjustment function and is difficult to adapt to the needs of different working conditions. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a QR code inkjet printing device and an online gravure inkjet printing device. The QR code inkjet printing device can control the inkjet printing component to adjust its position according to the printing requirements, adapting to different working conditions.

[0006] The technical solution to the problem of this utility model is to provide a QR code inkjet printing device, including at least one inkjet printing element, which is disposed above the paper to be printed; it also includes at least one straight line module, wherein the inkjet printing element is slidably connected to the straight line module, the straight line module is horizontally arranged, and its length direction is perpendicular to the length direction of the paper.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This utility model provides a QR code inkjet printing device, the specific structure of which is as follows:

[0026] like Figure 1 and Figure 2As shown, the QR code inkjet printing device includes at least one inkjet printer 1, which is positioned above the paper 5 to be printed. It also includes at least one linear module 2, with the inkjet printer 1 slidably connected to the linear module 2. The linear module 2 is horizontally positioned, and its length direction is perpendicular to the length direction of the paper 5. In use, the inkjet printer 1 can be adjusted in position within the width range of the paper 5 according to the working conditions, achieving seamless integration with gravure printing production and improving production efficiency.

[0027] In some embodiments, the linear module 2 is a single-axis linear motor module. Compared with traditional lead screw modules or belt modules, the single-axis linear motor module has higher motion speed, acceleration and positioning accuracy, which can meet the stringent requirements of the inkjet printing production line for inkjet printing speed and accuracy.

[0028] In some embodiments, the coding element 1 is movable in a vertical direction. Specifically, it also includes a connector 3 and a motor 8. The coding element 1 is slidably connected to the linear module 2 via the connector 3. The connector 3 includes a mounting base 31, which is slidably connected to the linear module 2. The connector 3 also includes a connecting seat 33, which is connected to the coding element 1. The connector 3 also includes an electric lifting rod 32 for driving the connecting seat 33 to move in a vertical direction. The electric lifting rod 32 is electrically connected to the motor 8, and its end is connected to the mounting base 31. In use, the electric lifting rod 32 is driven by the motor 8 to move the connecting seat 33 connected to it, thereby adjusting the vertical height of the coding element 1 and adjusting its coding distance as needed to further adapt to changes in working conditions. The integrated horizontal and vertical movement modules have the advantage of simplifying space occupation.

[0029] As a further improvement to the above embodiment, the connector 3 also includes a vertically arranged guide portion 34 and a slider sleeved on the outside of the guide portion 34. The guide portion 34 is connected to the mounting base 31, and the connecting base 33 is integrally connected to the slider. To prevent the mass of the inkjet printer 1 and the connecting base 33 from causing the electric lifting rod 32 to bear a bending moment, a guide portion 34 is further added to guide the vertical movement of the connecting base 33.

[0030] In some embodiments, a plurality of paper feed rollers 4 for guiding the paper 5 are also included. At least two paper feed rollers 4 are disposed below at least one inkjet printer 1, and the line connecting their centers is located on the same horizontal plane, providing a stable and flat support plane for the paper 5 to be printed, and preventing the paper 5 from warping or sagging during the inkjet printing process.

[0031] In some embodiments, a drying assembly 6 is also provided downstream of at least one inkjet printer 1. The drying assembly 6 includes at least one UV drying lamp, which is arranged sequentially along the width direction of the paper 5 to ensure that the UV drying lamp covers the paper 5 when curing the ink.

[0032] In some embodiments, a leveling component 7 is also provided upstream of at least one inkjet printer 1. The leveling component 7 includes a first leveling plate and a second leveling plate. One side of the paper 5 abuts against the first leveling plate, and the other side of the paper 5 abuts against the other leveling plate, so as to level the paper 5 before inkjet printing, effectively eliminating the curling, wrinkles or stress generated in the previous process of the paper 5, and providing an absolutely flat printing surface for inkjet printing.

[0033] In some embodiments, a PLC is also included, which is electrically connected to the linear module 2 and the electric lifting rod 32, so as to pre-set the coding parameter schemes for different products.

[0034] This utility model also provides an online gravure printing and coding device, including a gravure printer and the QR code coding device as described above, with the gravure printer located upstream of the QR code coding device.
