Description

Technical Field

[0001] This utility model relates to the field of industrial printers, and more specifically, to a paper roll splicing device for industrial printers. Background Technology

[0002] Before printing begins in an industrial printer, the printing media typically needs to be fed from one side of the paper feed roller, around the rear swing arm, and through the printing platform. At the printing platform, the media is sprayed by the print head and then conveyed to the delivery system by friction rollers. For continuous printing, roll changing and splicing operations are usually required before the printing media runs out. During roll changing and splicing, one end of the printing media needs to be secured to prevent splicing difficulties caused by it detaching from the fabric winding system.

[0003] For example, utility model patent CN220998578U discloses a printer roll changing clamping device and a fabric take-up system. This printer roll changing clamping device includes a left support plate and a right support plate. A first fabric winding roller and a clamping beam are respectively arranged between the left and right support plates. Cylinder mounting plates are respectively arranged on the inner sides of the left and right support plates, and telescopic cylinders are arranged on the cylinder mounting plates. A clamping roller mounting seat is provided at the telescopic end of the telescopic cylinder. A clamping roller is arranged between a pair of clamping roller mounting seats. The clamping roller is arranged opposite to the clamping beam, and the channel between the clamping roller and the clamping beam forms a roll changing clamping channel. This printer roll changing clamping device can clamp the printing medium during unwinding and rewinding, preventing the printing medium from detaching from the fabric winding roller during the unwinding and take-up process. However, the disclosed structure of this printer roll changing clamping device clamps the medium inside the paper winding shaft, resulting in a narrow space that is inconvenient for manual operation. Utility Model Content

[0004] To increase the operating space for personnel during roll changing and to increase the convenience of splicing printing media when changing rolls, the technical solution adopted by this utility model is: an industrial printer paper roll splicing device, including a frame and a lifting magnetic suction rod, wherein the lifting magnetic suction rod includes a pair of lifting vertical rods and a magnetic suction horizontal rod connected to the top of the pair of lifting vertical rods, and the pair of lifting vertical rods can be lifted and lowered on the frame;

[0005] The magnetic crossbar spans over the paper roll and has a magnet magnetically attached to it. The magnet is used to hold one end of the paper to be spliced ​​on the paper roll between the magnet and the magnetic crossbar.

[0006] Based on the above, in order to achieve smooth lifting, a pair of lifting cylinders are provided on the frame, and the extension and retraction ends of the lifting cylinders are respectively connected to the bottom of the lifting vertical rod.

[0007] Based on the above, the frame is provided with a slide rail, and the lifting vertical rod is provided with a slider that slides in cooperation with the slide rail.

[0008] Based on the above, in order to store the lifting rod during descent, a hollow storage rod is also connected to the outside of the lifting rod. The hollow storage rod is fixed to the frame and is used to store the lifting rod.

[0009] Based on the above, in order to avoid interference, the length of the magnetic crossbar is greater than the width of the paper roll.

[0010] Based on the above, in order to raise the lifting magnetic rod directly and promptly after splicing the printing media to avoid interference, the magnet is magnetically attached to the lower surface of the magnetic horizontal bar.

[0011] Based on the above, the magnetic crossbar is arranged parallel to the central axis of the paper roll.

[0012] Based on the above, in order to facilitate the loading and unloading of paper rolls, a pair of support arms for supporting the paper rolls are rotatably provided on the frame, and the magnetic crossbar is located above the support arms.

[0013] Based on the above, in order to increase structural stability, the frame is also equipped with crossbeams and several paper winding rollers.

[0014] This invention represents a substantial advancement over existing technologies. Specifically, the industrial printer paper roll splicing device provided by this invention features a lifting magnetic rod above the paper roll, with a magnet mounted on the rod. During paper roll changing operations, the magnet attracts the lifting magnetic rod, clamping one end of the paper to be spliced ​​between the magnet and the rod. This avoids splicing difficulties caused by the paper detaching from the winding roller system. Furthermore, the lifting action of the magnetic rod expands the operating space for splicing the paper, improving ease of operation and accommodating operators of different heights.

[0015] Therefore, this industrial printer paper roll splicing device can increase the operating space for personnel when changing rolls and increase the convenience when splicing printing media. Attached Figure Description
