Description

Technical Field

[0001] This invention relates to the field of printing press technology, and in particular to a printing apparatus and a printing press. Background Technology

[0002] Glitter printing adds a layer of glitter material to the surface of printed materials, giving them a shiny effect. This printing process can be applied to various materials, such as art paper, coated paper, and art paper. The principle behind glitter printing is to alternately print glitter material and printing ink. First, ink is sprayed onto the printed material, then glitter is sprayed onto the uncured ink. Finally, a curing lamp cures the glitter, resulting in a glitter print. During the spraying process, uncured glitter spills onto the printed material; if not cleaned promptly, this can affect the printing effect and thus printing efficiency. Summary of the Invention

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] It should be understood that in the description of this application, the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0035] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0036] like Figures 1-17 As shown, the printing apparatus of some embodiments of the present invention includes a printing carriage 1, a powder spraying mechanism 2, a curing lamp 3, and a powder suction head 4. The powder spraying mechanism 2 can spray glitter onto the substrate 5, the curing lamp 3 can cure the glitter onto the substrate 5, and the powder suction head 4 can absorb the uncured glitter.

[0037] When the printing device is working, the printing carriage 1 is mounted on the moving mechanism, so that the powder spraying mechanism 2, the curing lamp 3, and the powder suction head 4 can move together with the printing carriage 1. During processing, ink is first sprayed onto the substrate 5 by the inkjet mechanism, and then glitter is sprayed onto the ink on the substrate 5 by the powder spraying mechanism 2. The ink and glitter are cured by the curing lamp 3, and finally the uncured glitter is absorbed by the powder suction head 4.

[0038] The powder spraying mechanism 2 is installed on the printing carriage 1. The powder spraying mechanism 2 includes a powder storage bottle 21, a bottle cap 22 covering the mouth of the powder storage bottle 21, a powder-dispensing impeller 23 disposed in the bottle cap 22, a drive assembly 24 detachably connected to the bottle cap 22, and a powder spraying head 25 installed on the bottle cap 22. The drive assembly 24 is driven by the powder-dispensing impeller 23. The bottle cap 22 has a powder outlet 221 corresponding to the powder-dispensing impeller 23. The powder spraying head 25 has a powder spraying port 251 communicating with the powder outlet 221 and an air blowing interface 252 communicating with the powder spraying port 251.

[0039] When the powder spraying mechanism 2 is working, the glitter in the powder storage bottle 21 enters the bottle cap 22. The driving component 24 drives the powder-dispensing impeller 23 to rotate, which can stir the glitter in the bottle cap 22 and make the glitter evenly enter the powder spraying port 251 of the powder spraying head 25 from the powder outlet 221 of the bottle cap 22. At this time, the air blowing interface 252 of the powder spraying head 25 is connected to the air blowing pipe, so that the glitter in the powder spraying port 251 is blown onto the surface of the substrate 5, thus realizing the powder spraying operation.

[0040] The curing lamp 3 is installed on the printing carriage 1 and located on one side of the powder coating mechanism 2. For example, the curing lamp 3 is an ultraviolet curing lamp.

[0041] The powder suction head 4 is installed on the printing carriage 1 and located on the side of the curing lamp 3 away from the powder spraying mechanism 2. The powder suction head 4 has a first suction pipe connector 41 and a first powder suction port 42 connected to the first suction pipe connector 41. In this way, when the first suction pipe connector 41 is connected to the suction pipe, the first powder suction port 42 is in a negative pressure state, thereby being able to adsorb uncured glitter powder.

[0042] Based on the above structural setup, the powder spraying mechanism 2 can spray glitter onto the substrate 5, the curing lamp 3 can cure the glitter onto the substrate 5, and the powder suction head 4 can absorb the uncured glitter, thus achieving both powder spraying and powder suction effects and improving printing efficiency.

[0043] like Figure 2 and5 As shown, in some embodiments, the drive assembly 24 includes a motor 241, a first gear 242, a second gear 243, and a connecting rod 244. The motor 241 is detachably connected to the bottle cap 22. The first gear 242 is mounted on the main shaft of the motor 241. The second gear 243 meshes with the first gear 242. The lower end of the connecting rod 244 is mounted on the second gear 243, and the upper end of the connecting rod 244 passes through the bottle cap 22 and connects to the powder-dispensing impeller 23. Thus, starting the motor 241 drives the first gear 242 to rotate, the first gear 242 drives the second gear 243 to rotate, and finally, the connecting rod 244 drives the powder-dispensing impeller 23 to rotate. In addition, to ensure the stability of the rotation of the connecting rod 244, a bearing is installed at the part of the connecting rod 244 that passes through the bottle cap 22.

[0044] like Figure 2 and 5 As shown, in some embodiments, the drive assembly 24 further includes a connector 245, a pin 246, and a tension spring 247. The upper end of the connector 245 has a hook 2451, which engages with the outer edge of the bottle cap 22. One side of the connector 245 is hinged to the outer wall of the powder spraying head 25 via the pin 246, and the other side of the connector 245 is connected to the outer wall of the powder spraying head 25 via the tension spring 247. Thus, by pulling the connector 245 upwards, the hook 2451 can be removed from the outer edge of the bottle cap 22. At this time, the pin 246 and the tension spring 247 can be removed from the outer wall of the powder spraying head 25, making the installation and disassembly of the drive assembly 24 convenient. It also facilitates the meshing assembly between the first gear 242 and the second gear 243, and the tension spring 247 can achieve a buffering and shock absorption effect.

[0045] like Figure 6 As shown in the arrangement, in some embodiments, the powder spray nozzle 251 is arranged vertically, so that the powder spray nozzle 251 is perpendicular to the substrate 5, which can achieve precise powder spraying.

[0046] like Figure 6 As shown in the second arrangement, in some embodiments, the powder spray nozzle 251 is inclined, so that the powder spray nozzle 251 and the substrate 5 form an angle. By adjusting the inclination angle of the powder spray nozzle 251, the powder spraying range can be adjusted.

[0047] like Figure 6 As shown in arrangements three and four, in some embodiments, the powder spray head 25 further includes a second suction pipe connector 253 and a second powder suction port 254 communicating with the second suction pipe connector 253. Thus, by connecting the second suction pipe connector 253 to the suction pipe, the second powder suction port 254 can adsorb glitter from the substrate 5.

[0048] like Figure 6As shown in Arrangement 3, in some embodiments, both the second powder suction port 254 and the powder spraying port 251 are vertically arranged. This enables precise powder spraying and suction.

[0049] like Figure 6 As shown in Arrangement 4, in some embodiments, both the second powder suction port 254 and the powder spraying port 251 are inclined and their lower ends are close to each other. In this way, by adjusting the inclination angle of the powder spraying port 251 and the second powder suction port 254, the powder spraying range and the powder suction range can be adjusted.

[0050] like Figure 9-12 As shown, in some embodiments, the powder suction head 4 has an air blowing port 43 and an air blowing pipe connector 44 communicating with the air blowing port 43. In this way, by connecting the air blowing pipe connector 44 to the air blowing pipe, the glitter on the substrate 5 can be blown through the air blowing port 43, which helps the first powder suction port 42 of the powder suction head 4 to remove the glitter cleanly.

[0051] like Figures 11-12 As shown, in some embodiments, the air blowing port 43 is located in the middle of the powder suction head 4, and the first powder suction port 42 is located around the outer periphery of the air blowing port 43. In this way, the air blowing port 43 blows the glitter on the substrate 5 to all sides and is sucked away by the first powder suction port 42.

[0052] like Figures 9-10 As shown, in some embodiments, the first powder suction port 42 is located in the middle of the powder suction head 4, and the air blowing port 43 is located around the outer periphery of the first powder suction port 42. In this way, the air blowing port 43 blows the glitter on the substrate 5 towards the center where it is sucked away by the first powder suction port 42.

[0053] like Figures 13-14 As shown, in some embodiments, the powder suction head 4 has an air blowing pipe 45 communicating with the air blowing port 43 and a powder suction pipe 46 communicating with the first powder suction port 42. In this way, the glitter on the substrate 5 is blown up by the air blowing pipe 45 and the blown glitter is sucked away by the powder suction pipe 46, thereby achieving the purpose of powder removal.

[0054] like Figure 15-17 As shown, in some embodiments, the dust suction head 4 includes an ultrasonic oscillator 47, which is installed at the air blowing port 43. Thus, the ultrasonic oscillator 47 converts the uniform positive pressure airflow from the air blowing port 43 into a variable airflow that oscillates at a certain frequency. This excites the glitter on the surface of the substrate 5, blows it away from the substrate 5, and then uses the negative pressure airflow from the first dust suction port 42 to carry the blown glitter away from the surface of the substrate 5, achieving non-contact ultrasonic dust removal. The method of removing glitter using the ultrasonic oscillator 47 is efficient, has long-lasting performance, and is simple and convenient to maintain.

[0055] In the above embodiments, for example, the blowing pipe is connected to a booster pump, and the suction pipe is connected to a negative pressure pump.

[0056] Other embodiments of the printing press of the present invention include inkjet printing apparatus of some embodiments.

[0057] Based on the above structure, the printing press can spray glitter onto the substrate 5 through the powder spraying mechanism 2, the curing lamp 3 can cure the glitter onto the substrate 5, and the powder suction head 4 can absorb the uncured glitter, thus achieving both powder spraying and powder suction effects and improving printing efficiency.

[0058] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
