[0028] Application of IC protection belt multi-row split cutting burr-free cutter structure, see Figure 2 :

[0029] It comprises N IC protection belts 100, and N is a natural number greater than or equal to 1;

[0030] M groups of cutters 200, each group of cutters 200 comprising two IC protection belt multi-row split cutting burr-free cutters, specifically an upper cutter 210 and a lower cutter 220, wherein M = N + 1;

[0031] and an upper rotating shaft 300 and a lower rotating shaft 400, which are arranged in parallel and spaced apart in the height direction;

[0032] A plurality of upper knives 210 are fixed on the upper rotating shaft 300 at equal intervals, and a plurality of lower knives 220 are fixed on the lower rotating shaft 400 at equal intervals. The outer circular knife faces of the upper knives 210 of each group of knives 200 are arranged towards the outer circular knife faces of the lower knives 220. The outer side straight faces 25 of the upper knives 210 are arranged towards the outer side straight faces 25 of the lower knives 220, forming a relative knife gap D1. The starting end of the first knife edge bevel 21 of the upper knives 210 is lower than the opposite lower edge of the inner recessed right-angle groove 30 of the lower knives 220, and the starting end of the first knife edge bevel 21 of the lower knives 220 is higher than the opposite upper edge of the inner recessed right-angle groove 30 of the upper knives 210. Each group of knives 200 forms an upper machining surface 201 and a lower machining surface 202. The upper machining surface 201 includes the outer circular knife face region of the lower knives 220, and the lower machining surface 202 includes the outer circular knife face region of the upper knives 220.

[0033] The interval between the adjacent two groups of knives 200 forms a working channel 500.

[0035] The working principle is as follows. When the two groups of knives are fixed on the upper rotating shaft and the lower rotating shaft and arranged at intervals, a fixed shearing angle is formed at the intersection of the upper and lower circular knives. The outer side straight faces of each group of knives form a knife gap D1, and D1≥D. The upper knives and the lower knives rotate to eat material at the shearing angle position. The knife tip A of the upper knife first engages with the knife tip B of the lower knife to shear the sheet corresponding to the IC protection strip. Through the fixed knife edge angles α, β and γ, the sheet is cut to form a fixed inclination angle under the action of the shearing force. During the cutting of the sheet, the knife tip A of the lower knife exerts a downward pressure on the cut sheet. The cut sheet enters the knife gap with the knife tip A of the upper knife at a fixed angle, and then enters the lower part of the vertex C of the inner recessed right-angle groove of the lower knife to form engagement again, thereby ensuring that the cut surface of the cut sheet is subjected to secondary shearing to perform secondary deburring treatment. The knives are assembled on the upper rotating shaft and the lower rotating shaft, and then the IC protection strip is arranged to pass through, which reduces the equipment cost of deburring and burr removal and reduces the workload of the workers.
