Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, specifically an inkjet printing device. Background Technology

[0002] A printing unit (also known as an inkjet printer or jet printer) is a device that sprays ink or other liquid substances onto a printing medium (such as paper, fabric, plastic, metal, etc.) through nozzles to form patterns or text. Inkjet printing technology is widely used in printing, marking, inkjet printing, and electronics manufacturing. Current printing solutions involve simply spraying water-based ink through four sets of printheads (processing liquid-color-white-adhesive), followed by oven drying, B-film coating, and finally collection into rolls.

[0003] However, the water-based ink solution, which uses four printheads—processing liquid, color ink, white ink, and adhesive ink—to print onto the film, has the following disadvantages:

[0004] 1. Water-based inkjet printing requires a large amount of water-based ink, which places high demands on drying. Because the film is very thin, the drying temperature cannot be set too high, otherwise it will cause the film to deform. Therefore, the drying time is relatively long, which affects production efficiency.

[0005] 2. Printing requires high standards for ink viscosity, corrosiveness, and environmental friendliness. With current technology, water-based adhesives have relatively low viscosity, making them prone to peeling off during later transfer processes.

[0006] Meanwhile, a secondary inkjet printing technology is adopted, in which the processing liquid, color inkjet, and white inkjet are first printed, dried, and then rewound and repositioned for printing. However, this secondary inkjet printing may cause misalignment and is cumbersome to operate. Therefore, an inkjet printing device is proposed to address the above problems. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a printing device.

[0008] The technical solution adopted by this utility model to solve its technical problem is: the inkjet printing device of this utility model includes an inkjet printing carriage body, and an inkjet printing carriage base plate is fixedly installed at the bottom of the inkjet printing carriage body.

[0026] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1-2 As shown, a printing device includes a printing carriage body 1, and a printing carriage base plate 2 is fixedly installed at the bottom of the printing carriage body 1.

[0029] The printhead assembly 3 is mounted on the base plate 2 of the printing carriage. The printhead assembly 3 includes a treatment liquid nozzle 31, a color nozzle 32, a white nozzle 33, and an adhesive nozzle 34. The treatment liquid nozzle 31 and the white nozzle 33 are fixedly installed at the front and rear of the left side of the base plate 2, respectively. The color nozzle 32 and the adhesive nozzle 34 are fixedly installed at the front and rear of the right side of the base plate 2, respectively. Gloss lamps 4 are fixedly installed at the rear of both sides of the bottom of the printing carriage body 1. During operation, the printhead assembly 3 is fixedly mounted on the base plate 2, and then the printing carriage body 1 prints onto the adhesive film. During printing, the treatment liquid nozzle 31, color nozzle 32, and white nozzle 33 all use water-based inks. The treatment liquid nozzle 31 sprays the treatment liquid onto the adhesive film to increase ink adhesion. The color nozzle 32 sprays colored water-based ink to print the desired pattern. The white nozzle 33 sprays white water-based ink as an intermediate layer for transfer. After applying white ink, the transferred pattern will not break. The glue nozzle 34 uses UV glue, which is cured by irradiation with varnish lamps 4 fixed on both sides. After printing, the entire process is completed by drying and rewinding in an oven. Therefore, this utility model uses a combination of water-based ink and UV glue to complete the printing process in one go. The UV glue is dried by irradiation with varnish lamps 4 before use, and the water-based ink is dried in a drying tunnel before lamination to complete the entire printing process. This makes the device convenient and quick to use. At the same time, the UV glue has a much higher viscosity than the water-based glue, which can solve the problem of strong adhesion in application. The one-time printing can avoid the rewinding process required for secondary positioning of the glue. One machine can complete all the steps and solve the printing misalignment problem of secondary positioning printing. Since the glue is cured by irradiation with varnish lamps 4, the drying tunnel only needs to dry the water-based glue, which greatly saves the drying time and improves the overall work efficiency.

[0030] Example 2

[0031] Please see Figure 3-4 As shown in the first embodiment, another implementation of this utility model also includes a printhead cover 5. The printhead cover 5 is disposed at the bottom of the ink carriage base plate 2, and the printhead assembly 3 is located inside the printhead cover 5. A disassembly assembly is provided inside the ink carriage base plate 2, and the printhead cover 5 is installed to the ink carriage base plate 2 through the disassembly assembly. During operation, the printhead cover 5 is installed to the ink carriage base plate 2 through the disassembly assembly, and the printhead cover 5 can protect the printhead assembly 3 during printing and prevent ink splashing.

[0032] The disassembly assembly includes mounting slots 7 on the left and right sides inside the ink carriage base plate 2. The lower surface of the mounting slots 7 extends to the outside of the ink carriage base plate 2. A mounting plate 6 is installed inside the mounting slots 7 via a snap-fit ​​assembly. The mounting plate 6 is installed with the nozzle cover 5 via the mounting assembly. During operation, the snap-fit ​​assembly facilitates the installation and disassembly of the mounting plate 6 and the mounting slots 7, and the mounting assembly also facilitates the installation and disassembly of the mounting plate 6 and the nozzle cover 5. Therefore, the nozzle cover 5 is easy to disassemble, clean, and replace.

[0033] The mounting assembly includes a groove 13 formed inside the mounting plate 6. One side of the groove 13 extends to the outside of the mounting plate 6, and the other side of the groove 13 has a through slot 15. The top of the nozzle cover 5 has a threaded hole 16 corresponding to the through slot 15 inside the mounting plate 6. A mounting bolt 14 passes through the through slot 15 and is threadedly connected to the threaded hole 16. During operation, the mounting bolt 14 is rotated by rotating the top of the mounting bolt 14 located inside the groove 13, and the mounting bolt 14 can be rotated out of the threaded hole 16. After the mounting bolt 14 is rotated out, the mounting plate 6 and the nozzle cover 5 can be disassembled and separated.

[0034] The snap-fit ​​assembly includes a sliding groove 8 formed at the center of the front and rear surfaces inside the mounting slot 7. A slider 10 is slidably connected inside the sliding groove 8. A spring 9 is fixedly connected between the slider 10 and the sliding groove 8.

The spring 9 has a rebound force after being squeezed, which facilitates the reset of the slider 10 and the lock block 12. Then, after the lock block 12 is completely removed from the inside of the slot 11, the mounting plate 6 can be removed from the inside of the mounting slot 7, so that the printhead cover 5 and the mounting plate 6 can be disassembled from the printhead base plate 2. After the mounting plate 6 is removed from the printhead base plate 2, the mounting bolt 14 is rotated so that the mounting bolt 14 is rotated out from the threaded hole 16, which allows the printhead cover 5 and the mounting plate 6 to be disassembled, thus facilitating the disassembly, cleaning and replacement of the printhead cover 5.
