Abstract

This utility model provides an automatic rewinding device for a UV flatbed printer, comprising a UV flatbed printer body, an unwinding mechanism, a rewinding mechanism, and an isolation detection mechanism. The unwinding mechanism and the rewinding mechanism are respectively located at the two ends of the UV flatbed printer body. The rewinding mechanism includes a housing, a rewinding shaft, and a first guide roller. The fabric on the unwinding mechanism passes sequentially through the UV flatbed printer body and the first guide roller, and is then rewound by the rewinding shaft. The fabric on the unwinding mechanism is printed by the UV flatbed printer body and then rewound by the rewinding mechanism, which greatly improves the continuous printing efficiency of soft materials such as roll fabric. By setting an isolation film to be rewound along with the fabric, the problem of sticking or smudging caused by the fabric not being dry can be avoided. A camera can be used to check whether there is residual ink on the isolation film that comes into contact with the printed fabric. If there is residual ink, it means that the fabric is not dry, and the rewinding speed can be reduced to extend its UV curing time and reduce the sticking problem.

Description

Technical Field

[0001] This utility model relates to the field of UV flatbed printing, and in particular to an automatic rewinding device for a UV flatbed printer. Background Technology

[0002] A UV flatbed printer is a digital printing device that uses UV curing technology to print images obtained through design software or a scanner. This device can print directly on almost any hard or soft material surface, offering high versatility in printing media. It also boasts fast printing and drying speeds, making it suitable for high-volume industrial production. During operation, multiple printheads work together, moving at high speed along the X-axis. Ink droplets are ejected onto the substrate surface and immediately pass through the UV lamp irradiation area located to the side of the printhead, causing the ink to cure rapidly without requiring natural air drying. However, when using this device for continuous printing on soft materials such as roll-to-roll fabrics, frequent movement and alignment of the substrate are necessary to ensure it is flat on the printing platform. This operation is time-consuming and requires manual labor, impacting the overall production speed of the machine. Utility Model Content

[0032] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Please refer to Figures 1 to 3 This utility model provides an automatic winding device for a UV flatbed printer, including a UV flatbed printer body 2, an unwinding mechanism 1, a winding mechanism 3, and an isolation detection mechanism 4.

[0034] The unwinding mechanism 1 and the winding mechanism 3 are respectively located at the two ends of the UV flatbed printer body 2.

[0035] The winding mechanism 3 includes an outer shell 33, a winding shaft 32 and a first guide roller 31. The fabric on the unwinding mechanism 1 passes through the UV flatbed printer body 2 and the first guide roller 31 in sequence, and is then wound up by the winding shaft 32. The winding shaft 32 is connected to a drive motor.

[0036] The isolation detection mechanism 4 is disposed inside the outer shell 33. The isolation detection mechanism 4 includes an isolation film unwinding roller 41, a second guide roller 42, and a camera 43.

[0037] The isolation film is wound on the unwinding roller 41, and the isolation film is pulled by the first guide roller 31 and the second guide roller 42 in sequence and then wound up by the winding shaft 32.

[0038] The camera 43 is located in the traction channel between the first guide roller 31 and the second guide roller 42, and is aligned with the isolation membrane of the traction channel;

[0039] In use, the fabric on the unwinding mechanism 1 is printed by the UV flatbed printer body 2 and then wound up by the winding mechanism 3, which greatly improves the continuous printing efficiency of soft materials such as roll fabric. By setting an isolation film to be wound up with the fabric, the problem of sticking or smudging caused by the fabric not being dry can be avoided. The camera 43 can check whether there is residual ink on the isolation film that is in contact with the printed fabric. If there is residual ink, it means that the fabric is not dry. The winding speed can be reduced to extend its UV curing time and reduce the sticking problem.

[0040] In this embodiment, the camera 43 is connected to a display, and the content captured by the camera 43 can be viewed on the display.

[0041] In this embodiment, an ultraviolet lamp 5 is also included. The ultraviolet lamp 5 is disposed inside the outer casing 33 and is aligned with the printed fabric. The ultraviolet lamp 5 improves the curing efficiency of the ink printed on the fabric.

[0042] In this embodiment, a deviation correction mechanism 6 is also included. The deviation correction mechanism 6 is disposed inside the outer casing 33 and is used to prevent the fabric from deviating from its designated position.

[0043] In this embodiment, the correction mechanism 6 includes a connecting rod and a correction buckle disposed on the connecting rod. The correction buckle is slidably mounted on the connecting rod and fixed by bolts.

[0044] In this embodiment, the unwinding mechanism 1 and the winding mechanism 3 have the same structure.

[0045] The working principle of this utility model is as follows:

[0046] After the fabric on the unwinding mechanism 1 is printed by the UV flatbed printer body 2, it is wound up by the winding mechanism 3, which greatly improves the continuous printing efficiency of soft materials such as roll fabric. By setting an isolation film to be wound up with the fabric, the problem of sticking or smudging caused by the fabric not being dry can be avoided. The camera 43 can check whether there is residual ink on the isolation film that is in contact with the printed fabric. If there is residual ink, it means that the fabric is not dry. The winding speed can be reduced to extend its UV curing time and reduce the sticking problem.

[0047] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0048] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
