Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, and in particular to an inkjet printing equipment. Background Art

[0002] In the current field of printing equipment technology, full-page printing is a common requirement, especially in the production of advertisements and posters. Full-page printing means that the entire surface of the printed material is covered with printed content to ensure the integrity and visual impact of the picture. However, when performing full-page printing, the printing range often needs to exceed the edge of the printed material to ensure that the printed picture can completely cover the printed material.

[0003] When printing full page, the printing material is placed on the printing platform. In order to ensure that the printed image can completely cover the printing material, the printing range will be set slightly larger than the printing material. In this way, during the printing process, the ink will not only be sprayed on the printing material, but also on the part of the printing platform that exceeds the printing material, forming a picture without printing material.

[0004] However, there is a problem with this method: when the printing range exceeds the printing material, the part of the printing platform that is not covered by the printing material will be filled with ink. When replacing new printing materials or turning over the printing, the ink remaining on the printing platform will contaminate the new printing materials, causing the printed image to be destroyed. This not only affects the printing effect, but also increases the printing cost and time cost because the contaminated image needs to be reprinted. Therefore, it is particularly critical for us to propose a new inkjet printing device. Summary of the invention

[0005] The purpose of the present invention is to provide an inkjet printing device to solve the problem mentioned in the background art that when replacing new printing materials or turning over for printing, the ink remaining on the printing platform will contaminate the new printing materials, causing the printed images to be destroyed. This not only affects the printing effect, but also increases the printing cost and time cost because the contaminated images need to be reprinted.

[0006] To achieve the above-mentioned purpose, the present invention provides an inkjet printing device, including a first printing platform, an ink collecting device and a printing device, wherein a first printing material is placed on the first printing platform, and the size of the first printing material is larger than the size of the first printing platform. The ink collecting device is located below the first printing platform, and its size is larger than the size of the first printing platform, and can completely cover the first printing platform. More than one inkjet head is installed on the printing device for printing images.

[0007] Preferably, the first printing platform includes a first suction hole and a suction force generating system for adsorbing printing materials.

[0008] Preferably, the first printing platform comprises a suction cup and a suction force generating system for absorbing printing materials.

[0009] Preferably, it also includes a second printing platform, wherein the first printing platform and the second printing platform together form a combined platform, and the printing platforms are properly arranged to suit the sizes of commonly used printing materials. The size of the ink collecting device is larger than that of the combined platform and can cover all printing platforms.

[0010] Preferably, the first printing platform and the second printing platform are evenly distributed, and the printing platforms can be arranged according to the size of the printing material, so that the printing material can always completely cover the printing platform carrying the material.

[0011] Preferably, the first printing platform includes a first suction hole and a suction force generating system for adsorbing printing materials, and the second printing platform includes a second suction hole and a suction force generating system for adsorbing printing materials.

[0012] Preferably, the first printing platform and the second printing platform both include suction cups and suction generating systems for absorbing printing materials.

[0013] Preferably, it also includes a third printing platform, the first printing platform is suitable for placing a third printing material, the first printing platform and the second printing platform are suitable for placing the second printing material when combined, and the first printing platform, the second printing platform and the third printing platform are suitable for placing the first printing material when combined.

[0014] Preferably, it also includes a conveying system for moving the first printing material.

[0015] Preferably, the conveying system comprises a driving roller, a passive roller and one or more conveyor belts.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the inkjet printing device, by setting an ink collecting device located below the printing platform and having a size larger than the printing platform, the excess ink splashed during the printing process can be effectively collected to prevent the ink from contaminating the printing platform and subsequent printing materials. This design not only keeps the printing platform clean, but also ensures the quality of the printed image. The printing device of the present invention is equipped with multiple inkjet heads, which can achieve faster and more uniform printing effects and improve printing efficiency. At the same time, the suction holes or suction cups on the printing platform firmly fix the printing materials through the suction force generated, prevent the movement or wrinkling of the materials during the printing process, and further ensure the accuracy and quality of the printing. By introducing the concept of a combined printing platform, the device of the present invention can also adapt to printing materials of different sizes, providing greater flexibility and convenience. This design not only reduces the adjustment time when changing printing materials, but also enables the device to cope with more types of printing needs. By being equipped with a conveying system, the present invention realizes the automatic feeding and removal of printing materials, further improves production efficiency, and reduces the labor intensity of operators.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides an inkjet printing device, such as Figure 1-Figure 8 As shown, it includes a first printing platform 100, an ink collecting device 400 and a printing device 500. A first printing material 200 is placed on the first printing platform 100. The size of the first printing material 200 is larger than the size of the first printing platform 100. The ink collecting device 400 is located below the first printing platform 100 and is larger than the size of the first printing platform 100, and can completely cover the first printing platform 100. More than one inkjet head 501 is installed on the printing device 500 for printing pictures. When full-page printing is performed, the size of the printing picture 300 is set to be larger than the size of the first printing material 200, so that the printed picture can completely cover the first printing material 200. The printing excess area 301 will be printed on the ink collecting device 400 and collected in the waste ink collection bucket. When turning over for printing or replacing new printing materials, the first printing platform 100 is clean and will not contaminate the first printing material 200. The ink collecting device 400 is a square collection tank to recycle excess ink.

[0030] In this embodiment, the first printing platform 100 includes a first suction hole 110 and a suction force generating system for adsorbing printing materials.

[0031] Specifically, the first printing platform 100 includes a suction cup 120 and a suction force generating system for absorbing printing materials.

[0032] Furthermore, it also includes a second printing platform 600. The first printing platform 100 and the second printing platform 600 together form a combined platform. The proper arrangement of the printing platforms is suitable for the commonly used printing material sizes. The size of the ink collecting device 400 is larger than the size of the combined platform and can cover all printing platforms.

[0033] Furthermore, the first printing platform 100 and the second printing platform 600 are evenly distributed, and the printing platforms can be arranged according to the size of the printing material, so that the printing material can always completely cover the printing platform that carries the material.

[0034] Furthermore, the first printing platform 100 includes a first suction hole 110 and a suction force generating system for adsorbing printing materials, and the second printing platform 600 includes a second suction hole 610 and a suction force generating system for adsorbing printing materials.

[0035] Furthermore, the first printing platform 100 and the second printing platform 600 both include a suction cup 120 and a suction force generating system for adsorbing printing materials.

[0036] Furthermore, it also includes a third printing platform 700. The first printing platform 100 is suitable for placing the third printing material 220. The first printing platform 100 and the second printing platform 600 are suitable for placing the second printing material 210 after being combined. The first printing platform 100, the second printing platform 600 and the third printing platform 700 are suitable for placing the first printing material 200 after being combined.

[0037] Furthermore, it also includes a conveying system 800 for moving the first printing material 200 .

[0038] Furthermore, the conveying system 800 includes a driving roller 810 , a passive roller 820 and one or more conveyor belts 830 .

[0039] It is worth noting that Figure 7 and 8 As shown, the printing direction may be scanning printing along the Y-axis printing direction 901 or array printing along the X-axis printing direction 902 .

[0040] When the inkjet printing device of the present invention is used, first, the printing material is placed on the printing platform, and these platforms (such as the first printing platform 100, the second printing platform 600, etc.) are equipped with suction holes or suction cups and corresponding suction generating systems. When the printing material is placed on the platform, the suction generating system is activated, and the material is firmly fixed on the platform through the suction holes or suction cups to ensure that the material does not move during the printing process, thereby ensuring the printing accuracy.

[0041] Next, the printing device 500 starts to work, and the inkjet head 501 thereon starts to print ink according to a preset pattern. During the full-page printing process, in order to ensure that the picture can completely cover the printed material, the printing range will be slightly larger than the actual size of the material. In this way, the edge of the printed picture will extend outside the printing platform.

[0042] At this time, the ink collecting device 400 plays a key role. Because it is located below the printing platform and is large enough to completely cover the printing platform, the ink that exceeds the printing material will be directly printed on the ink collecting device. The waste ink is then collected in the waste ink collection bucket, thereby preventing the ink from contaminating the printing platform or subsequent printing materials.

[0043] When one side is printed, if you need to turn it over or replace new printing materials, there is no residual ink on the printing platform, so the new printing materials will not be contaminated. This process greatly improves the quality and efficiency of printing.

[0044] In addition, the device is also equipped with a conveying system 800 for automatically moving the printing material. The conveying system can smoothly convey the material into and out of the printing area through the cooperation of the driving roller 810, the passive roller 820 and the conveyor belt 830, further improving the automation and efficiency of printing.

[0045] Finally, it should be noted that the electronic components of the printing device 500, conveying system 800, etc. in this embodiment are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively, and the specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
