The assembly 200 includes a bidirectional screw rod 1 220 and a bidirectional screw rod 2 230. A slide rod 210 is provided above the bidirectional screw rod 1 220 and the bidirectional screw rod 2 230. The slide rod 210, the bidirectional screw rod 1 220, and the bidirectional screw rod 2 230 are all rotatably connected to the side frame 100. Both ends of the bidirectional screw rod 1 220 and the two ends of the bidirectional screw rod 2 230 are screwed and connected with a clamping arm 240. One end of the fixed rod 130 is fixedly sleeved with a gear 2 131. One end of the support roller 110 is fixedly connected to a gear 1 11. Gear 1 111 and gear 2 131 are meshed, and one end of a side frame 100 is fixedly connected to a motor 120. The output end of the motor 120 is in transmission connection with the other end of the support roller 110. The motor 120 drives the support roller 110 to rotate. The support roller 110 drives the fixed rod 130 to rotate through the gear 111 and the gear 2 131, thereby driving the three circular knives 150 to rotate in the opposite direction, cutting the material between the support roller 110 and the circular knife 150. It is necessary to adjust the three circular knives 150. When the distance between the two circular knives 150 is adjusted, the two-way screw rod 1 220 is rotated so that the two-way screw rod 1 220 drives the two-way screw rod 2 230 to rotate in the opposite direction. The rotation of the two-way screw rod 1 220 and the two-way screw rod 2 230 drives the two clamping arms 240 connected to each other to move toward each other, so that the clamping arms 240 adjacent to the two sides of the circular knife 150 clamp and drive the circular knife 150 to move, so that the circular knives 150 located on both sides move toward each other, thereby realizing the adjustment of the distance between the three circular knives 150 when the circular knife 150 rotates.

[0024] One end of the bidirectional screw rod 1 220 is fixedly sleeved with a gear 3 221, and one end of the bidirectional screw rod 2 230 is rotatably sleeved with a gear 4 231. The gear 3 221 is meshed with the gear 4 231, so that the bidirectional screw rod 1 220 drives the bidirectional screw rod 2 230 to rotate through the gear 4 231, thereby causing the clamping arms 240 adjacent to the circular knife 150 to move synchronously, thereby facilitating the movement of the circular knife 150. A sliding groove 232 is provided on the outer wall of one end of the bidirectional screw rod 230, and the inner wall of one end of the sliding groove 232 is rotatably connected to two connecting rods 1 233. One end of the connecting rod 1 233 is rotatably connected to the connecting rod 2 234. One end of the two connecting rods 234 is rotatably connected to a connecting block 237. A threaded hole is provided at one end of the bidirectional screw rod 230, and one end of the bidirectional screw rod 230 is screwed and connected to the screw 2 236. One end of the screw 2 236 rotates with the connecting block 237. The two-wheeled gear 230 is connected to the gear 231 by the screw 236, and the two-wheeled gear 230 is connected to the gear 231 by the screw 236. The two-wheeled gear 230 is connected to the gear 231 by the screw 236. The two-wheeled gear 230 is connected to the gear 231 by the screw 236. The two-wheeled gear 230 is connected to the gear 231 by the screw 236. The two-wheeled gear 230 is connected to the gear 231 by the screw 236.

[0025] The outer wall of the other end of the fixing rod 130 is provided with an insertion hole 132, and the other end of the fixing rod 130 is provided with a fixing module 140, the fixing module 140 includes a bearing 141, the outer wall of the bearing 141 is embedded and fixedly connected with the outer wall of one support roller 110, and the inner ring side wall of the bearing 141 is fixedly connected with a limiting cylinder 142, the outer wall of the limiting cylinder 142 is provided with a threaded hole, and the outer wall of the limiting cylinder 142 is screwed and connected with a screw 143, one end of the fixing rod 130 is connected with the other support roller 1 10 is movably connected, and screw rod 143 is rotated to disengage screw rod 143 from socket 132, and fixing rod 130 is withdrawn outward from one side of the other side frame 100, completing the disassembly of the three circular knives 150, making it easier to limit and remove fixing rod 130. The bottom end of clamping arm 240 and bearing 241 are both sleeved with fixing rod 130, and the bottom end of clamping arm 240 and bearing 241 do not directly contact fixing rod 130, avoiding interference between fixing rod 130, clamping arm 240 and bearing 241.

[0026] Working principle: When in use, the motor 120 drives the supporting roller 110 to rotate, and the supporting roller 110 drives the fixed rod 130 to rotate through the gear 1 111 and the gear 2 131, thereby driving the three circular knives 150 to rotate in the opposite direction, so as to cut the material between the supporting roller 110 and the circular knife 150. When the distance between the three circular knives 150 needs to be adjusted, the hand wheel 222 at one end of the bidirectional screw rod 1 220 is rotated, so that the bidirectional screw rod 1 220 drives the bidirectional screw rod 2 230 to rotate in the opposite direction through the gear 3 221 and the gear 4 231. The rotation of the bidirectional screw rod 1 220 and the bidirectional screw rod 2 230 drives the two clamping arms 240 connected to each other to move toward each other, so that the clamping arms 240 adjacent to both sides of the circular knife 150 clamp and drive the circular knife 150 to move, so that the circular knives 150 on both sides move toward each other, thereby realizing the adjustment of the distance between the three circular knives 150 when the circular knife 150 rotates;

[0027] When the circular knife 150 needs to be replaced or removed, the hand wheel 222 at one end of the two-way screw rod 230 is held to keep the two-way screw rod 230 stationary, thereby rotating the screw rod 236, so that the screw rod 236 rotates relative to the two-way screw rod 230, so that the screw rod 236 drives the connecting block 237 to move to one end, thereby causing one end of the connecting rod 1 233 to break away from the contact and squeeze the inner wall of the extrusion cylinder 235. Due to the rotational sleeve connection between the two-way screw rod 230 and the gear 4 231, the two-way screw rod 230 is rotated so that the two clamping arms 240 on the two-way screw rod 230 move closer to the middle, thereby releasing the clamping of the circular knives 150 at the two side positions, and removing the circular knife 150 in the middle position from the fixing rod 130. The screw rod 143 is rotated to disengage the screw rod 143 from the socket 132, and the fixing rod 130 is withdrawn outward from the side of the other side frame 100 to complete the removal of the three circular knives 150.
