[0029] The following further describes the present utility model in conjunction with the accompanying drawings and embodiments:

[0030] A cutting mechanism of a slitter, see Figures 1 to 5 , which includes a slitter body 1. A bracket 2 is erected in the middle of the surface of the slitter body 1. A driving assembly 3 is arranged inside the bracket 2. A group of limiting mechanisms 4 are symmetrically arranged inside the middle of the driving assembly 3. A number of cutting knives 5 are evenly sleeved outside the limiting mechanism 4;

[0031] The limiting mechanism 4 includes a limiting groove 401, which is arranged inside the middle of the driving assembly 3. A limiting plate 402 is clamped inside the limiting groove 401. A number of clamping plates 403 are evenly distributed on the surface of the limiting plate 402. Among them, the limiting plate 402 and the clamping plate 403 are integrally formed. The thickness of the limiting plate 402 is less than the depth of the limiting groove 401. A group of limiting rods 404 are fixedly connected to both sides of the surface of the limiting plate 402. A buckle 405 is fixedly connected to the top of the limiting rod 404. A limiting screw ring 406 is sleeved outside the limiting rod 404. In the present utility model, by removing the limiting screw ring 406, the limiting rod 404 is not restricted, so that the limiting plate 402 can be moved and adjusted in the limiting groove 401. When the limiting rod 404 completely enters the inside of the limiting groove 401, the outer end of the clamping plate 403 will be flush with the surface of the support rod 301. At this time, the cutting knives 5 are not restricted, and the distance between the cutting knives 5 can be adjusted. After the adjustment is completed, the limiting rod 404 is pulled out by hooking the buckle 405 with an external hook body. At the same time, the clamping plate 403 is clamped into the inner side of the corresponding cutting knife 5, and a number of cutting knives 5 can be quickly and uniformly limited, improving the adjustment efficiency. After that, the limiting rod 404 is limited by the limiting screw ring 406.

[0032] It should be noted that the bracket 2 includes a base 201. A group of bases 201 are symmetrically attached to the surface of the slitter body 1. A group of hydraulic cylinders 202 are embedded inside the base 201. The movable end of the hydraulic cylinder 202 is connected to a top frame 203. A group of positioning plates 204 are symmetrically and fixedly connected to the side of a group of bases 201. In the present utility model, the hydraulic cylinder 202 effectively drives the top frame 203 to move up and down, so as to adjust the height of the cutting knife 5 inside the top frame 203, which is convenient for adapting to materials of different thicknesses.

[0033] It should be noted that the driving component 3 includes a support rod 301. A set of clamping frames 302 are symmetrically attached to the outer sides of both ends of the support rod 301. A bolt 303 passes through the support rod 301 and the inside of the clamping frames 302. A hexagonal nut 304 is threadedly sleeved on the outside of the bolt 303. A set of rotating rods 305 are symmetrically fixedly connected to the side surfaces of the set of clamping frames 302. The end of the right rotating rod 305 is connected to a motor 306. A bracket 307 is provided outside the motor 306. Among them, the set of rotating rods 305 are movably clamped inside both sides of the top frame 203, and the bracket 307 is fixedly connected to the top frame 203. The utility model effectively drives the rotation of the rotating rod 305, the clamping frame 302 and the support rod 301 through the motor 306, thereby driving the rotation of the cutting knife 5 on the outside of the support rod 301, realizing the rotary cutting of the material by the cutting knife 5. By removing the hexagonal nut 304 and the bolt 303, the support rod 301 can be separated from the clamping frame 302, so as to facilitate the addition or reduction of the cutting knife 5 on the outside of the support rod 301.

[0034] It should be emphasized that the cutting knife 5 includes a blade body 501. Two sets of connecting rods 502 are symmetrically fixedly connected to the upper and lower sides inside the blade body 501. One end of the connecting rod 502 away from the blade body 501 is connected to a groove frame 503. Among them, the clamping plate 403 is matched and clamped inside the groove frame 503, and a number of groove holes for the movement of a number of clamping plates 403 are provided on the surface of the support rod 301. The utility model realizes the limitation of the blade body 501 through the cooperation between the groove frame 503 and the clamping plate 403.

[0035] Working principle: By removing the limit ring 406, the limit rod 404 is not restricted, so as to facilitate the movement and adjustment of the limit plate 402 in the limit groove 401. When the limit rod 404 completely enters the inside of the limit groove 401, the outer end of the clamping plate 403 will be flush with the surface of the support rod 301. At this time, the cutting knife 5 is not restricted, and the distance between the cutting knives 5 can be adjusted. After the adjustment is completed, the limit rod 404 is pulled out by hooking the buckle 405 with an external hook body. At the same time, the clamping plate 403 is clamped inside the corresponding cutting knife 5, and a number of cutting knives 5 can be quickly and uniformly limited. Then, the limit rod 404 is limited by the limit ring 406. The motor 306 drives the rotation of the rotating rod 305, the clamping frame 302 and the support rod 301, thereby driving the rotation of the cutting knife 5 on the outside of the support rod 301. Finally, the hydraulic cylinder 202 drives the top frame 203 to move up and down, so as to adjust the height of the cutting knife 5 inside the top frame 203, and different thickness materials can be adapted for slitting.
