[0023] See also Figure 1-6 , the utility model provides a technical solution:

[0024] A device for equidistantly cutting an aluminum-copper composite strip comprises a main body 1, wherein a cutting roller 2 is provided on the inner wall of the main body 1, a positioning roller 3 is provided on the inner wall of the main body 1 on one side of the cutting roller 2, a winding roller 4 is provided on the inner wall of the main body 1 on the other side of the cutting roller 2, a center shaft 21 is provided on the outer side of the cutting roller 2 at the middle part, side shafts 22 are respectively provided on the outer sides of both ends of the cutting roller 2, an infrared sensor 221 is provided on the outer side of the side shaft 22, the width of the copper-aluminum composite strip is detected by the infrared sensor 221, cutting blades 23 are provided on the outer sides of the side shaft 22 and the center shaft 21, a positioning mechanism 24 is provided inside the cutting roller 2, and the positioning mechanism 24 comprises a servo motor 241, the output end of the servo motor 241 is fixedly connected to a driving gear 242, a linkage bar 243 is provided on both sides of the driving gear 242, one end of the linkage bar 243 is fixedly connected to a linkage ring 244, and the linkage ring 244 is connected to the side shaft 22 through a transmission column 245.

[0025] In this embodiment, please refer to Figure 4At the connection between the outer side of the lateral shaft 22 and the cutting blade 23, at least two connecting parts 25 are provided. The inner wall of the cutting blade 23 is provided with connecting grooves 231 with the same number as the connecting parts 25. The cutting blade 23 is connected to the lateral shaft 22 through the connecting part 25 and the connecting groove 231. A control groove 222 is provided at one end of the lateral shaft 22. The inner wall of the control groove 222 is movably connected with a rotating shaft 223. A first magnetic ring 224 is provided on the outer side of the rotating shaft 223. In this embodiment, the position of the first magnetic ring 224 can be adjusted by rotating the rotating shaft 223 by external force, thereby controlling whether the first magnetic ring 224 generates suction on the second magnetic ring 254, thereby controlling whether the connecting block 252 is embedded in the inner cavity of the connecting groove 231.

[0026] In this embodiment, please refer to Figure 5-6 The connecting member 25 includes a sleeve chamber 251, and the inner cavity of the sleeve chamber 251 is provided with a connecting block 252. One end of the connecting block 252 is provided with a second magnetic ring 254. The corresponding surfaces of the second magnetic ring 254 and the first magnetic ring 224 attract each other. In this embodiment, when the first magnetic ring 224 corresponds to the second magnetic ring 254, the second magnetic ring 254 will be attracted to move backward, and the connecting block 252 will be driven to move backward by the second magnetic ring 254. The backward movement of the connecting block 252 will cause it to detach from the inner cavity of the connecting groove 231, thereby disconnecting the lateral shaft 22 from the cutting blade 23.

[0027] In this embodiment, please refer to Figure 4 The corresponding surfaces of the two linkage bars 243 are provided with gear grooves, and the gear grooves are engaged with the outer edges of the driving gears 242. In this embodiment, by controlling the rotation of the driving gear 242, the two linkage bars 243 can be driven to move toward each other or move away from each other.

[0028] In this embodiment, please refer to Figure 3 、 Figure 6 , multiple springs 253 are also provided in the inner cavity of the sleeve chamber 251, and movable grooves 211 are opened on the outer sides of both ends of the cutting roller 2. The inner wall of the movable groove 221 is adapted to the transmission column 245. In this embodiment, when the second magnetic ring 254 is subjected to suction to cause the connecting block 252 to move downward, the spring 253 is squeezed to cause it to deform. When the suction disappears, the spring 253 rebounds, lifts the connecting block 252 to return to its original position, and re-enters the inner cavity of the connecting groove 231, so that the connecting groove 231 is re-fixed on the outer side of the side shaft 22. By providing the infrared sensor 221, the transmission column 245 is moved along the outer side of the infrared sensor 221, thereby adjusting the position of the side shaft 22.

[0029] In this embodiment, please refer to Figure 1 、 Figure 4 、 Figure 5A controller is also provided on the inner side of the main body 1. The controller is electrically connected to the infrared sensor 221. The controller is also electrically connected to the servo motor 241 through a relay and a contactor. In this embodiment, the infrared sensor 221 emits an infrared signal to detect the edge position of the aluminum-copper composite strip and determine the width of the aluminum-copper composite strip. The controller controls the infrared sensor 221 to adjust the position of the cutting blade 23 according to the width of the aluminum-copper composite strip, and automatically adjusts the position of the cutting blade 23 to achieve equidistant cutting of the aluminum-copper composite strip.

[0030] Working principle of this utility model:

[0031] Step 1: When the aluminum-copper composite strip is being cut, the aluminum-copper composite strip is passed through the gap between the two positioning rollers 3, bypasses the outer side of the positioning roller 3, and is wound through the winding roller 4. During the winding process, the aluminum-copper composite strip is cut by the cutting blade 23 provided on the cutting roller 2, and the width of the aluminum-copper strip is detected by the infrared sensor 221 provided at both ends of the cutting roller 2, and the detected signal is sent to the controller. When the width of the aluminum-copper composite strip to be processed changes, the servo motor 241 is started by the controller, and the servo motor 241 provides power to drive the drive gear 242 to rotate. Since the outer edge of the driving gear 242 is meshed with the inner wall of the linkage bar 243, when the driving gear 242 rotates, it drives the two linkage bars 243 to move toward or away from each other, so that the linkage bar 243 pushes the linkage ring 244 to move, and drives the side shaft 22 through the transmission column 245 to move along the outer side of the cutting roller 2, so that the distance between the two side shafts 22 and the central axis 21 is increased or decreased at an equal distance, so that the positions of the two side shafts 22 can be synchronously adjusted according to the width of the aluminum-copper composite strip, so that the cutting blade 23 can cut the aluminum-copper composite strip and ensure that the width of the strips after cutting remains consistent;

[0032] Step 2: When the cutting blade 23 needs to be replaced or repaired, the rotating shaft 223 is rotated by external force so that it rotates along the inner wall of the control groove 222, so that the position of the first magnetic ring 224 changes. After the first magnetic ring 224 and the connecting member 25 are aligned one by one, the corresponding surfaces of the second magnetic ring 254 and the first magnetic ring 224 attract each other. Therefore, under the action of suction, the connecting block 252 moves deep into the inner cavity of the sleeve chamber 251 and squeezes the spring 253 to cause it to deform, so that the connecting block 252 is separated from the inner cavity of the connecting groove 231. By disconnecting the cutting blade 23 from the side shaft 22, the cutting blade 23 can be removed from the side shaft 22. During installation, the cutting blade 23 is re-sleeved on the position of the side shaft 22 and moved to the position of the connecting piece 25 so that the connecting piece 25 corresponds to the connecting groove 231. Then, the rotating shaft 223 is rotated again so that the rotating shaft 223 and the second magnetic ring 254 no longer correspond to each other, so that the suction force disappears, the spring 253 loses pressure and rebounds, and the spring 253 rebounds to lift the connecting block 252 to return it to its original position and enter the inner cavity of the connecting groove 231 again, so that the cutting blade 23 is fixed to the outside of the side shaft 22 again, and the installation is completed.
