Technical Field

[0001] This application relates to the field of paper roll processing, and in particular to a slitting device for paper rolls. Background Technology

[0002] Paper roll slitting is a key downstream process in the papermaking industry. The slitting paper rolls need to be labeled for tracking and management.

[0003] In related technologies, roll paper slitting is achieved by a slitting device. Specifically, the slitting device includes a tensioning frame and a slitting assembly. The tensioning frame and the slitting assembly are spaced apart. The roll paper is first tensioned and conveyed by the tensioning frame, and then slitting by the slitting assembly to achieve the slitting of the roll paper.

[0004] Furthermore, after the paper rolls are cut, they are manually transported to the coding station to be coded. This is not only inefficient, but also prone to misalignment of the coding due to paper deformation, resulting in poor coding effect. Therefore, it needs to be improved.

Furthermore, the mounting seats are fixed after sliding by the fasteners to improve the stability of the inkjet printer's operation.

[0013] Preferably, the tensioning frame further includes a slide rail and a plurality of sliders, the slide rail being disposed on the frame body, the plurality of sliders being slidably connected to the slide rail, and each of the mounting seats being disposed on each of the sliders.

[0014] By adopting the above technical solution, and by setting slide rails and multiple sliders, the sliding of the mounting base can be facilitated, and the stability of the sliding of the mounting base can be improved.

[0015] Preferably, the tensioning frame further includes a plurality of driving components, each of which is disposed on the mounting base and is used to drive each of the inkjet printers to move in the vertical direction.

[0016] By adopting the above technical solution and setting multiple driving components, the height position of the inkjet printer can be adjusted to meet different inkjet printing needs.

[0017] Preferably, the coding assembly further includes a plurality of heating lamps, which are located at one end of the frame near the second tension roller and below the first tension roller.

[0018] By adopting the above technical solution, multiple heating lamps are set up to heat and cure the printed paper roll, thereby improving the printing effect of the paper roll.

[0019] Preferably, the coding assembly further includes a reflector located on the side of the heating lamp away from the second tension roller.

[0020] By adopting the above technical solution and setting reflective elements, the light from the heating lamp is reflected to the coding area of ​​the roll paper, thereby improving the effect of heating and curing the roll paper.

[0021] Preferably, the inkjet printing assembly further includes an encoder, which is slidably connected to one end of the frame near the second tension roller along the width direction of the frame, and the encoder is located above the first tension roller.

[0022] By adopting the above technical solution and setting an encoder to calculate the conveying length of the paper roll, the accuracy of paper roll slitting is improved.

[0023] Preferably, the coding assembly further includes a connecting rope, one end of which is disposed on the encoder and the other end of which is disposed on the reflector.

[0024] By adopting the above technical solution and setting a connecting rope, the reflector is adjusted to follow the position of the encoder, thereby improving the coding effect of the roll paper.

[0038] The coding assembly 2 includes multiple coding machines 21, which are mounted on the upper side of the frame 11 and located at one end of the frame 11 near the second tension roller 13. The multiple coding machines 21 are spaced apart along the width direction of the frame 11 and located above the first tension roller 12.

[0039] In practical applications, the paper roll passes sequentially through multiple first tension rollers 12 and is wound sequentially around multiple second tension rollers 13 to tightly convey the paper roll to the slitting assembly, where the slitting assembly cuts the paper roll. During the tight conveying process, each inkjet printer 21 can spray ink onto the paper roll to achieve coding, enabling the paper roll to be coded before slitting, thereby improving coding efficiency and minimizing the occurrence of coding misalignment due to paper deformation, thus improving the coding effect on the paper roll.

The mounting seats 14 are slidably connected to the upper side of the frame body 11, with the sliding direction being the width direction of the frame body 11. Each inkjet printer 21 is mounted on each mounting seat 14. By sliding the mounting seats 14, the position of the inkjet printer 21 can be adjusted to change the inkjet printing position on the roll paper to meet different inkjet printing requirements. Each fastener 15 is threadedly connected to each mounting seat 14 and abuts against the frame body 11 to fix the mounting seat 14 after sliding, thereby improving the stability of the inkjet printer 21 during operation.

[0044] In some embodiments, the coding assembly 2 further includes a reflector 23, which is a thin paper with reflective properties. The reflector 23 is located on the side of the heating lamp 22 away from the second tension roller 13, so as to reflect the light of the heating lamp 22 to the coding area of ​​the roll paper, thereby improving the effect of heating and curing the ink on the roll paper and further improving the coding effect of the roll paper.

The direction of the slide is the width direction of the frame 11, and the encoder 24 is located above the first tension roller 12. It can calculate the conveying length of the roll paper, thereby improving the accuracy of roll paper cutting.

[0046] In some embodiments, the coding assembly 2 further includes a connecting rope 25, which is a steel wire rope. One end of the connecting rope 25 is fixedly connected to the encoder 24, and the other end is fixedly connected to the reflector 23, so that the reflector 23 can be adjusted to follow the position of the encoder 24 to improve the coding effect of the roll paper.
