Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and in particular to an integrated inkjet printing device. Background Technology

[0002] In related technologies, when double-sided printing is required on label paper, one side of the label paper needs to be printed first. After printing on one side, the label paper is cured and rolled up. Then, the worker moves the label paper to a peeling mechanism to peel off the release paper on the other side.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] The following is for reference. Figures 1 to 3 This invention describes an integrated inkjet printing device according to an embodiment of the present invention.

[0028] like Figures 1 to 2 As shown, the integrated inkjet printing equipment according to an embodiment of the present invention includes: a first printing module 100, a second printing module 200, a flipping device 300, a peeling mechanism 400, a laminating mechanism 500, and a conveying roller device 600; the first printing module 100 is used to print the front side of the substrate; the second printing module 200 is disposed in front of the first printing module 100 along a first direction and is used to print the back side of the substrate; the flipping device 300 is disposed between the first printing module 100 and the second printing module 200 and is used to flip the front and back sides of the substrate; the peeling mechanism 400 is disposed between the flipping device 300 and the second printing module 200 and is used to peel the first release paper from the substrate composite to obtain the substrate; the laminating mechanism 500 is disposed in front of the second printing module 200 along the substrate feeding direction and is used to laminate the second release paper with the printed substrate; the conveying roller device 600 is disposed along the substrate feeding path for conveying the substrate.

[0029] Understandably, this integrated inkjet printing equipment includes a first printing module 100, a second printing module 200, a flipping device 300, a peeling mechanism 400, a laminating mechanism 500, and a conveyor roller device 600. During use, the substrate is conveyed by the conveyor roller device 600, sequentially passing through the first printing module 100, the flipping device 300, the peeling mechanism 400, the second printing module 200, and the laminating mechanism 500. This allows the substrate to be printed on its front side first in the first printing module 100, followed by the flipping device 300 flipping the substrate to its front and back sides. The peeling mechanism 400 peels off the first release paper of the flipped substrate composite to obtain a separate substrate, which facilitates the second printing module 200 to print on the reverse side of the substrate. The printed double-sided substrate is conveyed by the conveying roller device 600 to the laminating mechanism 500 and laminated with the second release paper, thereby realizing double-sided printing of the substrate and peeling and re-lamination of the release paper. Therefore, the integrated inkjet printing equipment of this application can integrate double-sided printing with substrate release paper peeling and lamination processing equipment, thereby improving production efficiency, reducing labor costs, and saving floor space costs.

[0030] It is understood that the device also includes a worktable 700, and a flipping device 300 is disposed within the worktable 700. The flipping device 300 includes a first flipping rod 310, a second flipping rod 320, and a third flipping rod 330, all arranged along a horizontal plane. The first flipping rod 310 and the second flipping rod 320 are perpendicular to each other and both form a 45° angle with the first direction. The third flipping rod 330 is disposed on one side of the first flipping rod 310 and the second flipping rod 320 and is arranged along the first direction, so that the substrate can be flipped over sequentially by passing around the first flipping rod 310, the third flipping rod 330, and the second flipping rod 320. For example, as... Figure 3 As shown, in this embodiment, the substrate with the front side printed by the first printing module 100 comes to the flipping device 300 along the first direction and first passes around the first flipping rod 310. Since the first flipping rod 310 is horizontally set and forms a 45-degree angle with the first direction, the substrate's feeding direction after passing the first flipping rod 310 is perpendicular to the first direction. Then it comes to the third flipping rod 330, passes around the third flipping rod 330 and then passes around the second flipping rod 320, so that the substrate feeds along the first direction again and realizes the flipping of the front and back sides of the substrate.

[0031] It is understood that the peeling mechanism 400 includes a first drive mechanism and a peeling roller. The output end of the first drive mechanism is connected to the peeling roller and is used to drive the peeling roller to rewind and peel off the first release paper. For example, as...

The first unwinding roller 510 is used to unwind the second release paper, and the laminating roller 520 is used to laminate the substrate and the second release paper. For example, as Figures 1 to 2 As shown, in this embodiment, the first unwinding roller 510 is used to unwind the second release paper, so that it can be laminated with the substrate that has also been printed on the reverse side on the laminating roller 520.

[0033] Understandably, it also includes a control module. The first printing module 100 includes a first color printing unit 110 and a marking unit.

The sensor is used to sense the markings and transmit the signals to the control module. The control module is used to receive the signals from the sensor and control the start and stop of the printing unit according to the signals. For example, such as... Figures 1 to 2 As shown, in this embodiment, by setting a marking unit in the first printing module 100, color marks are made on the substrate while color printing is performed on the front side of the substrate. This allows the color marks to be sensed by a sensor when printing on the back side of the substrate in the second printing module 200. The sensor transmits the signal to the control module, which then controls the printing unit to print at the corresponding positions on the substrate, ensuring that the printing positions on the front and back sides of the substrate correspond to each other.

[0034] It is understood that the printing unit includes a second color printing unit 210 and a scratch-off silver printing unit 220, with the scratch-off silver printing unit 220 positioned behind the second color printing unit 210 along the material feeding direction of the substrate.

The scratch-off silver printing unit 220 performs scratch-off silver printing on the corresponding positions on the reverse side of the substrate, and then the second color printing unit 210 performs color printing on the corresponding positions on the reverse side of the substrate, thereby realizing the printing of various printing patterns on the substrate.

[0035] It is understood that the first printing module 100 includes a first flexographic printing unit 120, and the second printing module 200 includes a second flexographic printing unit 230. The first flexographic printing unit 120 is located in front of the first color printing unit 110 along the material feeding direction of the substrate and is used to apply varnish to the front side of the substrate. The second flexographic printing unit 230 is located in front of the second color printing unit 210 along the material feeding direction of the substrate and is used to apply varnish to the back side of the substrate. For example, as... Figures 1 to 2As shown, in this embodiment, a first flexographic printing unit 120 and a second flexographic printing unit 230 are respectively provided in the first printing module 100 and the second printing module 200, so as to apply varnish to the front and back sides of the substrate after color printing, thereby improving the surface gloss of the substrate and improving its waterproof and wear-resistant performance.

[0036] It is understood that the first printing module 100 includes a first curing unit, and the second printing module 200 includes a second curing unit and a third curing unit. The first curing unit is located between the first color printing unit 110 and the first flexographic printing unit 120, and is used to cure and dry the front side of the substrate. The second curing unit is located between the second color printing unit 210 and the second flexographic printing unit 230, and is used to cure and dry the back side of the substrate. The third curing unit is located at the foremost side of the second printing module 200 along the first direction, and is used to cure the entire substrate. For example, as... Figures 1 to 2 As shown, in this embodiment, a first curing unit and a second curing unit are respectively provided in the first printing module 100 and the second printing module 200, and a second curing is performed before the second release film is laminated, so as to achieve the drying effect as soon as possible.

[0037] Specifically, UV curing is used in the embodiments of this application.

The second unwinding roller 800 is used to unwind the substrate composite, and the pre-treatment module 900 is located at the output end of the second unwinding roller 800 along the material path of the substrate composite for pre-treating the substrate composite. For example, as... Figures 1 to 2 As shown, in this embodiment, the substrate composite is first released by the second unwinding roller 800 and pre-processed by the pre-processing module 900 before entering the first printing module 100 and other subsequent processing modules for processing. Pre-processing can improve the surface properties of the substrate composite, thereby improving the subsequent printing quality.

[0039] It is understood that the pretreatment module 900 includes a corona treatment unit 910 and a dust removal unit 920. The corona treatment unit 910 and the dust removal unit 920 are sequentially arranged along the material path of the substrate composite.
