AI Technical Summary
In existing technologies, traditional inkjet printing devices often have multiple printing modules in their design, resulting in excessive distance between the printhead and the curing device. This leads to ink seepage and ink splatter, affecting printing quality.
A first UV curing lamp is installed between the printheads, and ink collection devices and second UV curing lamps are installed on both sides of the mounting plate to shorten the distance between the printheads and the curing devices. The UV curing lamps are used to quickly cure the ink, and the ink is removed by the ink collection devices.
It achieves rapid ink curing, prevents seepage, improves printing color development, effectively removes ink splatter, and improves printing quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of printer technology, specifically to an inkjet printer printing mechanism. Background Technology
[0002] With the development and advancement of inkjet printing technology, its application fields are becoming increasingly widespread. There are numerous types of printing media, each with different characteristics, ink penetration properties, and curing requirements, which determine the image quality on the medium. Traditional inkjet printing modules have built-in curing devices located on both sides of the printhead module. When a multi-module printhead module is used, the lateral distance between the printhead modules increases. There is a time lag between the ink being ejected from the printhead onto the medium surface and then being applied to the medium by the curing devices on both sides. During this time lag, the ink applied to the medium will penetrate into the medium. When the ink encounters a medium with particularly strong penetration, it cannot cure in time, resulting in poor color development and a dark, distorted printed image. Furthermore, due to the increased lateral distance of the printhead modules, ink splatter occurs between the printhead and the medium during printing. As the printhead module moves, the airborne ink will disperse, either solidifying on the medium surface or accumulating on the printhead module. Over time, this accumulation will drip onto the medium, causing poor image quality. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, this utility model provides an inkjet printer printing mechanism that enables rapid ink curing, prevents ink from seeping into the medium, and greatly improves the printing color development effect.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] An inkjet printer printing mechanism includes a mounting plate with multiple printheads. A through hole is provided on the mounting plate between two adjacent printheads, and a first UV curing lamp is provided in the through hole. An ink collection device and a second UV curing lamp are respectively provided on both sides of the mounting plate from the inside to the outside.
[0006] Furthermore, the multiple printheads are arranged in two rows at equal intervals.
[0007] Furthermore, the mounting plate includes a base plate and side plates connected to both sides of the base plate. The print head and the first UV curing lamp are disposed on the base plate. The ink collection device is connected to the outside of the side plates, and the second UV curing lamp is connected to the outside of the ink collection device.
[0008] Furthermore, the ink collection device includes a suction head, an ink collection box, and a vacuum pump. The suction head is located at the bottom of the ink collection box, and the vacuum pump is connected to the ink collection box.
[0009] Compared with the prior art, the present invention has the following beneficial technical effects:
[0010] This invention relates to an inkjet printer printing mechanism that, by placing a first UV curing lamp between two adjacent printheads and second UV curing lamps on both sides of the mounting plate, shortens the distance between each printhead and the curing lamp, achieving rapid ink curing, preventing ink seepage into the media, and significantly improving the printing color development effect. Simultaneously, the ink collection devices on both sides of the mounting plate effectively eliminate airborne waste ink residue, preventing contamination of the printing media.

[0013] The components include: 1. Mounting plate; 11. Base plate; 12. Side plate; 2. Print head; 3. First UV curing lamp; 4. Ink collection device; 5. Second UV curing lamp. Detailed Implementation
[0014] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0015] Example 1
[0016] like Figure 1-2 As shown, an inkjet printer printing mechanism includes a mounting plate 1, on which a plurality of printheads 2 are provided. A through hole is provided on the mounting plate 1 between two adjacent printheads 2, and a first UV curing lamp 3 is provided in the through hole. From the inside to the outside, ink collection devices 4 and second UV curing lamps 5 are respectively provided on both sides of the mounting plate 1.
[0017] Specifically, multiple printheads 1 are arranged in two rows at equal intervals. The mounting plate 1 includes a base plate 11 and side plates 12 connected to both sides of the base plate 11. The printheads 2 and the first UV curing lamp 3 are mounted on the base plate 11. The ink collection device 4 is connected to the outside of the side plate 12, and the second UV curing lamp 5 is connected to the outside of the ink collection device 4.
[0018] The ink scrap collection device 4 includes a suction head, an ink collection box, and a vacuum pump. The suction head is located at the bottom of the ink collection box, and the vacuum pump is connected to the ink collection box. The vacuum pump generates negative pressure, drawing the scrap ink into the ink collection box. The suction head should be equipped with a one-way membrane to prevent backflow of waste ink. Alternatively, existing technology can be used for the ink scrap collection device.
