[0024] In the description of the present utility model, it should be understood that the terms indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model; in the description of the present utility model, the meanings of "a plurality" and "several" are at least two, such as two, three, etc., unless otherwise specifically defined.

[0025] Please refer to Figures 1 to 3 As shown, the present utility model is a digital printing rewinding cutting tool structure, including a tool rest support shaft 1, on which a plurality of blade holders 2 are slidably and adjustably installed. The tail end of the blade holder 2 is detachably connected to the blade part 3 by bolts. A support ring 5 is correspondingly arranged below the blade part 3, and the support ring 5 can be slidably and adjustably installed on the support ring roller 6; wherein, both ends of the tool rest support shaft 1 are rotatably and angularly connected to the cutting tool seat 4, and both ends of the support ring roller 6 are fixedly connected to the cutting tool seat 4.

[0026] The digital printing rewinding cutting tool structure of the present application is convenient to be installed and used on the rewinding material production line. The gap distance between adjacent support rings 5 can be adjusted in advance according to the pattern and size specifications of the rewinding material, which can be achieved by sliding the support ring 5 along the support ring roller 6 to the adjusted position. At the same time, the gap distance between adjacent blade parts 3 can be adjusted, which can be achieved by sliding the blade holder 2 along the tool rest support shaft 1 to the adjusted position. The adjustment is convenient, so that when the rewinding material is supported on the support ring 5, it is convenient to cut the product with the required slitting width specification through the blade part 3, and the operation is convenient, which helps to improve the cutting efficiency of the rewinding material.

[0027] In this specific embodiment, each blade holder 2 is slidably connected to the blade holder support shaft 1. At least two locking holes 20 are provided on the blade holder 2. In the provided locking holes 20, the blade holder 2 and the blade holder support shaft 1 are fixed in their relative positions by tightening screws; so that it is convenient to drive the blade part 3 of the blade holder 2 to slide and adjust.
