The ends of the moving shaft 51 are all installed with positioning mechanisms 2 52, and the positioning mechanisms 2 52 are detachably fixed with a plurality of reeling shafts 53 for reeling the dialysis paper after slitting. Specifically, the structure of the positioning mechanism 2 52 is the same as that of the positioning mechanism 1 2, and the mounting plate 5 is fixedly installed with a motor 54 for driving the rotating shaft 51 to rotate. When the dialysis paper roll is slid, the dialysis paper roll is sleeved on the outside of the positioning mechanism 1 2. At this time, the dialysis paper roll is sleeved on the outside of the two positioning plates 24, and the slider 22 is slid in the slide groove 211 by the adjusting member 26.

[0036] In this embodiment, the adjusting member 26 includes an adjusting rod 261 which is horizontally and rotatably mounted on the fixed rod 21. One end of the adjusting rod 261 extends into the slide groove 211 and is threadedly connected to the slider 22. When in use, a force is applied to the adjusting rod 261 to rotate it on the fixed rod 21, so that the slider 22 can slide in the slide groove 211. Since the adjusting rod 261 and the slider 22 are threadedly connected and have self-locking properties, the position of the slider 22 can be fixed without rotating the adjusting rod 261, which is convenient for use.

[0037] In this embodiment, the slitting assembly 4 includes a knife shaft 41 which is horizontally and rotatably mounted on the fixed plate 3, and a plurality of annular cutters 42 are fixedly mounted on the knife shaft 41 and arranged in an equidistant array along its axial direction. A horizontal limiting shaft 43 is rotatably mounted on the fixed plate 3 and located below the knife shaft 41, and grooves 431 are arranged in an equidistant array along its axial direction on the limiting shaft 43. The plurality of grooves 431 correspond to the plurality of annular cutters 42 one by one, respectively. The annular cutters 42 extend into the grooves 431 and fit with the inner walls of the grooves 431. When in use, the end of the dialysis paper is moved from the knife shaft 431 to the inner wall of the grooves 431. The shaft 41 passes through the opposite sides of the limit shaft 43, so that the end of the dialysis paper passes through the multiple annular cutters 42 in the horizontal direction, and the dialysis paper slitting effect can be achieved through the multiple annular cutters 42. The ends of the multiple dialysis papers after slitting are respectively wound on the winding shaft 53 outside the two positioning mechanisms 52, and the two motors 54 are controlled to make the two positioning mechanisms 52 rotate around the two rotating shafts 51 respectively. When the multiple dialysis papers after slitting are rolled up, the knife shaft 41 rotates on the fixed plate 3, so as to keep the dialysis paper slitting, and achieve the slitting effect of the dialysis paper roll.

[0038] In this embodiment, the multiple winding shafts 53 on the same positioning mechanism 52 are arranged in an equidistant array along the axial direction of the rotating shaft 51, and the winding shafts 53 on the two positioning mechanisms 52 are staggered. The ends of the multiple dialysis papers after slitting are respectively wound on the winding shafts 53 outside the two positioning mechanisms 52, so that the multiple dialysis papers after slitting are sequentially wound on the multiple winding shafts 53 outside the two positioning mechanisms 52, which effectively avoids the dialysis paper from being offset outside the winding shaft 53 when the dialysis paper after slitting is rolled up.

[0042] In this embodiment, the fixing plate 3 is inserted at the top of the base 1, and the fixing member 6 includes a fixing clamping rod 61 symmetrically hinged at the top of the base 1. The limiting holes 31 are symmetrically provided on the fixing plate 3, and the two fixing clamping rods 61 can respectively pass through the two limiting holes 31 and be clamped with the fixing plate 3. When in use, when the fixing plate 3 is disassembled, the two fixing clamping rods 61 are respectively rotated so that the two fixing clamping rods 61 can respectively pass through the two limiting holes 31, and a force is applied to the fixing plate 3 to separate it from the base 1, so that the fixing plate 3 can be disassembled. Conversely, when the fixing plate 3 is installed, the fixing plate 3 is inserted at the top of the base 1, and the two fixing clamping rods 61 respectively pass through the two limiting holes 31, and the two fixing clamping rods 61 are respectively rotated so that the two fixing clamping rods 61 are both clamped with the fixing plate 3, so that the fixing plate 3 and the base 1 can be fixed, and the operation is simple.

[0043] In this embodiment, a limiting guide mechanism 7 acting on the dialysis paper is installed on the base 1 and located on the outer side of the fixed plate 3. The limiting guide mechanism 7 is used to limit and guide the dialysis paper cut by the cutting component 4. By setting the limiting guide mechanism 7, the limiting guide effect of the dialysis paper cut by the cutting component 4 is achieved, which is beneficial for the device to cut the dialysis paper.

A vertical guide column 73 is symmetrically fixed on the top of the bracket 71, and a connecting plate 74 is slidably mounted on the two guide columns 73 along the axial direction of the guide column 73, and a horizontal limiting roller 2 75 is rotatably mounted on the connecting plate 74 and located directly above the two limiting rollers 1 72, and the two limiting rollers 2 75 are located on the same horizontal plane, and the top of the limiting shaft 43 of the limiting roller 2 75 is located on the same horizontal plane, and a vertical threaded rod 76 is rotatably mounted on the top of the bracket 71, and the threaded rod 76 threadedly penetrates the connecting plate 74, so that the end of the dialysis paper is moved from the limiting roller 1 72 and the limiting roller 2 near the vertical plate 11 during use. 75, and then pass through the opposite sides of the knife shaft 41 and the limiting shaft 43, so that the end of the dialysis paper passes through the multiple annular cutters 42 in the horizontal direction. After the multiple annular cutters 42 cut the dialysis paper, the multiple dialysis papers after cutting are passed between the opposite sides of the limiting roller 1 72 and the limiting roller 2 75 away from the vertical plate 11, and the threaded rod 76 is rotated to make the connecting plate 74 slide and move along the two guide columns 73 toward the bracket 71, so that the spacing between the limiting roller 1 72 and the limiting roller 2 75 is the same as the thickness of the dialysis paper, thereby achieving the limiting and guiding effect of the dialysis paper by the two limiting rollers 1 72 and the two limiting rollers 2 75, and by setting the connecting plate 74 to be slidably installed on the two guide columns 73 along the axial direction of the guide column 73, the spacing between the limiting roller 1 72 and the limiting roller 2 75 can be adjusted during use, so that the limiting and guiding mechanism 7 is suitable for limiting and guiding dialysis papers of different thicknesses.
