[0001] The utility model relates to the technical field of digital printing machines, in particular to a paper path layout structure of a digital machine. Background Art

[0002] Digital printing press, also known as universal flatbed printer or flatbed printer, is a major breakthrough in printing technology. It realizes the true sense of one-sheet printing, no need for plate making, and full-color image completion in one go. It is a successor to traditional printing presses. Digital printing presses are divided into industrial digital printing presses and office digital printing presses according to their different uses. They all have the advantages of very low investment, very low printing cost, optional printing size, high printing quality, small space occupation, few operators and very low operating cost. In addition, digital printing presses have a wide range of printing material types and thicknesses, so they have great investment advantages in the market. Digital printing presses, with their unique advantages, are gradually changing the landscape of the printing industry.

[0003] Most existing digital printers tend to use UV ink for printing. UV ink will cure very quickly when exposed to ultraviolet light. This can easily lead to the phenomenon of UV ink curing and clogging at the inkjet end of the print head during the use of the digital printer, thereby causing damage to the print head, reducing the efficiency of the device, and causing great inconvenience to the user.

[0009] As a further solution of the utility model: the top of the inkjet housing is connected with an ink delivery tube, and the ink delivery tube is located at one side of the fixing groove.

[0010] As a further solution of the utility model: an adapter is provided on the top of the UV lampshade, one end of the top of the adapter is connected to a first wiring harness tube, and the other end of the top of the adapter is connected to a second wiring harness tube.

[0011] As a further solution of the utility model: a plurality of groups of spaced limiting shafts are rotatably connected between the fixed side plates, and conveying rollers are connected between the limiting shafts. The conveying rollers are located below the inkjet housing and are parallel to the inkjet housing.

[0012] As a further solution of the utility model: the outer side of the conveying roller is provided with an anti-bias rubber sleeve.

[0013] Beneficial effects of the utility model:

[0014] When the utility model prints on paper, when the paper with UV ink attached passes under the UV lamp cover, the ultraviolet lamp arranged thereon irradiates the printed paper, and can cure the UV ink sprayed on the printed surface of the paper, thereby ensuring that the UV ink can be better attached to the paper, and because the UV lamp cover is tilted upward from the side close to the inkjet housing, and the angle between the UV lamp cover and the inkjet housing is 3.5 degrees, in combination with the UV lamp cover, the ultraviolet light emitted by the ultraviolet lamp can be redirected and blocked, thereby avoiding the ultraviolet light from irradiating the printing nozzle, causing the UV ink at the ink outlet end of the printing nozzle to be cured, and ensuring the normal use of the device.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-3 As shown, the paper path layout structure of the digital machine includes a fixed side panel 1. The fixed side panel 1 is the main structure, which is installed inside the digital printing machine and provides a mounting position for other structures to ensure the stability of other structures during operation. An inkjet housing 2 is arranged between the fixed side panels 1. A fixing groove 3 is provided through the top of the inkjet housing 2. A printing nozzle 4 is arranged inside the fixing groove 3. The fixing groove 3 provided on the inkjet housing 2 provides a mounting position for the printing nozzle 4 to ensure the stability of the printing nozzle 4 during operation. At the same time, the inkjet housing 2 also forms a covering protection for the printing nozzle 4 to prevent it from being damaged by bumps, thereby further improving the service life of the printing nozzle 4. The printing nozzle 4 is used for spraying UV ink. A UV lampshade 6 is arranged between the fixed side panels 1. The UV lampshade 6 is located behind the inkjet housing 2. An ultraviolet lamp is arranged at the bottom, and the UV lamp cover 6 is tilted upward from the side close to the inkjet housing 2, and the angle between the UV lamp cover 6 and the inkjet housing 2 is 3.5 degrees. By arranging an ultraviolet lamp on the UV lamp cover 6 to irradiate the printed paper, when the ultraviolet light irradiates the UV ink sprayed on the printing surface of the paper, the UV ink can be cured, thereby ensuring that the UV ink can be better attached to the paper, and because the UV lamp cover 6 is tilted upward from the side close to the inkjet housing 2, and the angle between the UV lamp cover 6 and the inkjet housing 2 is 3.5 degrees, in conjunction with the UV lamp cover 6, the ultraviolet light emitted by the ultraviolet lamp can be redirected and blocked, thereby avoiding the ultraviolet light from irradiating the printing nozzle 4, causing the UV ink at the ink outlet end of the printing nozzle 4 to be cured, thereby ensuring the normal use of the device.

[0022] In this embodiment, specifically, an ink supply tube 5 is connected to the top of the inkjet housing 2, and the ink supply tube 5 is located on one side of the fixed groove 3. The ink supply tube 5 is connected to the ink cartridge in the digital printer, thereby providing a steady supply of UV ink to the printing nozzle 4, ensuring the smooth progress of the printing work.

[0023] In this embodiment, specifically, an adapter seat 7 is provided on the top of the UV lamp cover 6, one end of the top of the adapter seat 7 is connected to a first wiring harness tube 8, and the other end of the top of the adapter seat 7 is connected to a second wiring harness tube 9. The first wiring harness tube 8 and the second wiring harness tube 9 are both used to connect lines, thereby providing power to the ultraviolet lamp while also ensuring that the staff can adjust and control the ultraviolet lamp.

[0024] In the present embodiment, specifically, a plurality of groups of spaced-apart limiting shafts 10 are rotatably connected between the fixed side plates 1, and conveying rollers 11 are connected between the limiting shafts 10. The conveying rollers 11 are located below the inkjet housing 2 and are parallel to the inkjet housing 2. The conveying rollers 11 are used to carry paper. When the conveying rollers 11 rotate, the purpose of transporting paper can be achieved. Both ends of the conveying rollers 11 are rotatably fixed to the fixed side plates 1 through the limiting shafts 10, forming a stable fixed structure, thereby ensuring the stability of the conveying rollers 11 during rotation. Since the conveying rollers 11 are parallel to the inkjet housing 2, the printing surface of the paper is directly opposite to the output end of the printing nozzle 4 during transportation, thereby ensuring that the UV ink sprayed during printing can be irradiated by the ultraviolet lamp on the printing surface of the paper, thereby curing the UV ink on the paper, thereby achieving the purpose of printing.

[0025] In this embodiment, specifically, an anti-bias rubber sleeve 12 is provided on the outer side of the conveying roller 11. By providing the anti-bias rubber sleeve 12 on the outer side of the conveying roller 11, the friction between the conveying roller 11 and the paper can be further increased, ensuring that the paper is not easily deviated when being transported, thereby ensuring the accuracy of the printing position.

[0026] The working principle of the utility model is as follows: when the device is used, the conveying roller 11 rotates to convey the paper, the ink delivery tube 5 is connected to the ink cartridge in the digital printer, and UV ink is provided to the printing nozzle 4, and the UV ink is sprayed onto the paper through the printing nozzle 4, thereby achieving the purpose of printing. When printing is completed, the conveying roller 11 conveys the printed paper to the bottom of the UV lamp cover 6, and the ultraviolet lamp arranged inside the UV lamp cover 6 irradiates the printed paper, and the UV ink sprayed on the printed surface of the paper is cured, thereby ensuring that the UV ink can be better adhered to the paper.

[0027] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
