[0029] like Figures 2 to 4 As shown, the triangular cutter for dividing rolls provided by this utility model includes a handle 2 and a triangular cutter body 1 mounted on the handle 2. One end of the handle 2 has a recessed mounting hole 21, in which the triangular cutter body 1 is mounted. Connecting holes 24 are respectively formed on the first sidewall 22 and the second sidewall 23 opposite to the first sidewall 22 of the mounting hole 21. A connecting member 3 passes through the connecting hole 24 to mount the triangular cutter body 1 into the mounting hole 21 of the handle 2. Preferably, the connecting member 3 is a bolt.

[0030] The triangular blade body 1 has a mounting portion 11 that engages in the mounting hole 21, and a blade head 12 disposed at one end of the mounting portion 11. Preferably, the mounting portion 11 is generally square. The mounting portion 11 partially engages in the mounting hole 21. Recessed holes 111 are provided on both sides of the mounting portion 11, and a connector 3 passes through a connecting hole 24 and connects to the recessed holes 111, thereby fixing the triangular blade body 1 in the mounting hole 21. The blade head 12 is generally triangular. The blade head 12 has a flat portion 121, a first beveled portion 122, and a support portion 124. One side of the blade head 12 is the flat portion 121, which is flush with the corresponding side of the mounting portion 11. The first beveled portion 122 is located at the top of the blade head 12 and gradually slopes downward toward the mounting portion 11. The first beveled portion 122 and the flat portion 121 are transitioned by an arc portion 123, and the arc portion 123 is tangent to the first beveled portion 122. The support portion 124 is located on the side of the first inclined portion 122 away from the flat portion 121 and is parallel to the flat portion 121. The angle between the support portion 124 and the first inclined portion 122 is a first included angle α. Preferably, the first included angle α is an obtuse angle. More preferably, the angle of the first included angle α is 125°. A second inclined portion 125 is provided between the support portion 124 and the mounting portion 11, and the angle between the second inclined portion 125 and the support portion 124 is a second included angle b. Preferably, the second included angle b is an obtuse angle. More preferably, the angle of the second included angle b is 120°. The second inclined portion 125 can enhance the stability of the cutting head 12 and prevent the cutting head 12 from breaking during processing.

[0031] The height between the vertex of the flat portion 121 of the triangular cutter body 1 and the bottom side of the mounting portion 11 is the first height H, and the height between the lower end of the second beveled portion 125 of the triangular cutter body 1 and the bottom side of the mounting portion 11 is the second height h. The relationship between the first height H and the width W of the mounting portion 11 is H = 3 * W. The relationship between the second height h and the width W of the mounting portion 11 is h = 1.6 * W.

[0032] Figure 5The illustration shows a roll 4 processed using the triangular cutter for roll material distribution provided by this invention. One side of the roll step 41 of the roll 4 is a sloping plane, and the other side is a vertical plane. This not only reduces the occurrence of arcs at the roll step 41, but also improves the yield and material utilization rate through the flat sloping plane. At the same time, since it is necessary to continue processing the small step to the required size cylinder, and traditional roll cutters may cause folding in subsequent processing, the sloping plane reduces the folding of the material.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
