[0052] By starting the second motor 7 and utilizing the second crawler 701 to drive the first pulley 2034 to rotate, one of the transmission gears 2033 is driven to rotate under the rotation of the first pulley 2034 and engage with the other transmission gear 2033, thereby realizing the relative rotation of the slitting roller 2031 and the lifting roller 2032, so that the coil can be preliminarily slit so that the width of the coil initially meets the requirements, wherein the pressure roller 202 and the support roller 201 can be utilized to enhance the stability of the coil during transportation.

[0053] In this application, a chute 301 is provided on the surface of the support platform 3, and an extension plate 303 is movably installed inside the chute 301 through a sliding plate 3031.

[0055] After the initial slitting is completed, the excess coils on both sides will be guided downward by the drop roller 305, and the remaining coils will be further transported downward along with the limiting roller frame 306. By starting the adjustment motor 3032, the forward and reverse screw rods 3033 can be rotated. Under the threaded cooperation between the forward and reverse screw rods 3033 and the sliding plates 3031 on both sides, the extension plates 303 on both sides are moved relative to each other, and then the support width of the current extension plate 303 is adjusted to support coils of different widths, and to ensure that the waste on both sides can be transferred downward. Finally, the waste on both sides will be stored in the collection frame 302 under the guidance of the drop roller 305 for later management.

[0056] In this application, a mounting bracket 403 is fixedly installed on the upper side of the second base 4, a guide cover 5 is fixedly installed on the upper side of the mounting bracket 403, a first motor 6 is fixedly installed on one side of the second base 4, a movable groove 404 is opened on one side of the second base 4, and a tensioning roller 405 is movably installed inside the movable groove 404 through a spring.

[0057] In order to ensure that the coil can enter the second expansion shaft 402 stably when winding, the tensioning roller 405 supports the wound coil under the action of the spring to avoid the coil from loosening during further slitting. By starting the first motor 6, the second pulley 904 can be driven to rotate in conjunction with the first crawler 601, thereby realizing the rotation of the several combined cutters 9022 in the slitting assembly 9 and further precise trimming of both sides of the coil.

[0058] In this embodiment, an auxiliary motor 501 is fixedly installed on one side of the guide cover 5, and a third expansion shaft 502 is fixedly installed on the output end of the auxiliary motor 501. A plurality of fixing rings 503 are installed on the shaft body of the third expansion shaft 502, and every two fixing rings 503 are arranged opposite to each other. A turntable 504 is installed on the outside of each fixing ring 503, and a cleaning brush 505 is provided on the surface of the turntable 504.

[0059] It should be noted that a collection bin 506 is fixedly mounted on the lower side of the guide cover 5, a collection port 5061 is provided on the upper side of the collection bin 506, a discharge door 5062 is provided on the outer side of the collection bin 506, and a guide exhaust fan 507 is fixedly mounted on one side of the collection bin 506. The air inlet of the guide exhaust fan 507 communicates with the collection bin 506 and the interior of the guide cover 5. A filter is provided at the air inlet of the guide exhaust fan 507.

[0060] During the slitting process, the auxiliary motor 501 is started to drive the third expansion shaft 502 to rotate, wherein a plurality of groups of fixing rings 503 are fixedly installed on the shaft body of the third expansion shaft 502, and each group of fixing rings 503 is respectively located on both sides of the adjacent combined cutter 9022, and a cleaning brush 505 is provided on the surface of the turntable 504, so that the combined cutter 9022 and the electromagnet plate 9021 at the current position can be cleaned, and at this position, the electromagnet plate 9021 releases the magnetic attraction of the iron chips, and thus, under the rotation guidance of the cleaning brush 505, cooperates with the guide cover 5 to transfer the iron chips to the collection port 5061, wherein the guide exhaust fan 507 is used to continuously perform negative pressure treatment on the collection port 5061, so that the iron chips are accumulated in the collection bin 506 to ensure that the iron chips will not fall to the contact position between the coil and the cutter during the continuous slitting process, thereby ensuring the slitting quality under continuous slitting.

[0061] In this embodiment, the slitting assembly 9 includes a shaft 901, which is rotatably mounted inside the mounting frame 403. A second pulley 904 is mounted on one end of the shaft 901. The output end of the first motor 6 is connected to the second pulley 904 through the first track 601. A plurality of sealing grooves 9051 are provided on the surface of the shaft 901, and a locking protrusion 905 is provided inside the sealing groove 9051. A plurality of mounting seats 902 are installed on the shaft body of the shaft 901, and an electromagnet plate 9021 is installed on the outside of the mounting seat 902. A combination cutter 9022 is installed on the outside of the plurality of electromagnet plates 9021 through a magnetic isolation ring 9023. In the present application, the combined cutter 9022 is composed of two circular rings, and the magnetic isolation ring 9023 can reduce the magnetic force of the electromagnet plate 9021, so as to avoid the interference of the magnetic force of the electromagnet plate 9021 on the combined cutter 9022 during the magnetic attraction process, resulting in the problem that iron filings are adsorbed on the combined cutter 9022 and cannot be cleaned. The electromagnet plates 9021 are arranged in groups, so as to ensure that the magnetic adsorption of the electromagnet plates 9021 is controlled separately as needed in the future, which not only ensures that the iron filings can be concentrated but also can cooperate with the subsequent structure to achieve the cleaning of the iron filings.

[0062] In the specific configuration, a fixing bracket 906 is installed at the other end of the shaft 901, and a plurality of groups of movable brushes 9061 are arranged on the outside of the fixing bracket 906. A connecting base 903 is fixedly installed on one side of the inner side of the mounting bracket 403, and the connecting base 903 is rotatably connected to the fixing bracket 906.

[0063] A power panel 9031 is installed on the outside of the connection base 903 , and a fixed brush 9032 is installed on one side of the inner wall of the connection base 903 . The fixed brush 9032 is electrically connected to a plurality of groups of movable brushes 9061 .

[0064] Among them, a mounting groove 907 is provided on one side of the inner wall of the sealing groove 9051, and a conductive slide rail 9053 is installed inside the mounting groove 907. A conductive sheet 9052 is installed inside the locking protrusion 905, and the conductive sheet 9052 is electrically connected to the conductive slide rail 9053. A power socket 9024 is provided at the bottom of the placement seat 902, and the power socket 9024 is electrically connected to the conductive sheet 9052, and the power socket 9024 is connected to the built-in coil of the electromagnet plate 9021;

[0065] Wire grooves 911 are provided on both sides of the mounting groove 907 , and the conductive slide rails 9053 are electrically connected to the corresponding movable brushes 9061 through cables 912 .

[0066] In order to achieve power transmission, the power panel 9031 is connected to the external power supply, so that the fixed brush 9032 can be electrically connected to the movable brush 9061 adjacent to the current position, wherein the movable brush 9061 can be rotated and switched to achieve magnetic control of each electromagnet plate 9021. After receiving electricity, the movable brush 9061 uses the cable 912 to electrically connect the conductive slide rail 9053 on the corresponding side with the conductive sheet 9052. As the power socket 9024 is electrically connected to the conductive sheet 9052, the electricity is connected to the built-in coil of the electromagnet plate 9021, which can make the current row of electromagnet plates 9021 magnetically adsorbed.

[0067] In the present application, a transfer ventilation pipe 910 is installed at the center of the fixed frame 906, a convergence groove 908 is opened on one side of the shaft body 901, and a number of extension channels 909 are opened on the outside of the convergence groove 908. Each extension channel 909 is interconnected with the adjacent sealing groove 9051. A control air pump 10 is installed on one side of the second base 4. The control air pump 10 is connected to the transfer ventilation pipe 910 through a pipeline, and a solenoid valve is built into the transfer ventilation pipe 910.

[0068] The gas is delivered by starting the control air pump 10, and the gas enters the convergence groove 908 through the pipeline, and then enters several extension channels 909 from the convergence groove 908. The extension channels 909 are connected with the adjacent sealing grooves 9051, so that the air pressure at the bottom of the adjacent sealing grooves 9051 increases, and the sealing grooves 9051 are sealed with the locking protrusions 905, so that the height of the locking protrusions 905 is increased, thereby cooperating with multiple locking protrusions 905 to realize the locking operation of the placement seat 902 for subsequent slitting operations. Conversely, starting the control air pump 10 to exhaust can realize the lowering of multiple locking protrusions 905 to adjust the slitting spacing of the placement seat 902 to meet the slitting of rolls of different widths.

[0069] The working principle of the automatic slitting device for steel strip coils:

[0070] When in use, the coil body 8 is first stored in the first expansion shaft 101, and one end of the coil body 8 is pulled and stored in the second expansion shaft 402. Then, the feeding motor 102 and the receiving motor 401 are started to respectively drive the first expansion shaft 101 and the second expansion shaft 402 to rotate, thereby ensuring that the steel strip coil can achieve stable conveying operation;

[0071] The second motor 7 is started to drive the first pulley 2034 to rotate using the second crawler 701. Under the rotation of the first pulley 2034, one of the transmission gears 2033 is driven to rotate and mesh with the other transmission gear 2033, thereby realizing the relative rotation of the slitting roller 2031 and the lifting roller 2032, so that the coil can be preliminarily slit. After the completion of the preliminarily slitting, the excess coils on both sides are guided downward by the drop roller 305 and stored in the collection frame 302 for later management.

[0072] By starting the first motor 6, the second pulley 904 can be driven to rotate in conjunction with the first crawler 601, thereby rotating the plurality of combined cutters 9022 in the slitting assembly 9 and further precisely trimming both sides of the coil;

[0073] During the slitting process, the auxiliary motor 501 is started to drive the third expansion shaft 502 to rotate, wherein a plurality of sets of fixing rings 503 are fixedly installed on the shaft body of the third expansion shaft 502, and each set of fixing rings 503 is respectively located on both sides of the adjacent combined cutters 9022, and a cleaning brush 505 is provided on the surface of the turntable 504, so that the combined cutters 9022 and the electromagnet plate 9021 at the current position can be cleaned, and at this position, the electromagnet plate 9021 releases the magnetic attraction of the iron chips, and thus, under the guidance of the rotation of the cleaning brush 505, the iron chips are transferred to the collection port 5061 in cooperation with the guide cover 5, wherein the guide exhaust fan 507 is continuously used to perform negative pressure treatment on the collection port 5061, so that the iron chips are accumulated in the collection bin 506;

[0074] During slitting, the shaft 901 rotates continuously, so that the position of the movable brush 9061 can be frequently adjusted. The fixed brush 9032 can be electrically connected to the movable brush 9061 adjacent to the current position by connecting to the external power supply through the power panel 9031. The movable brush 9061 can be rotated and switched to realize the magnetic force control of each electromagnet plate 9021. After receiving electricity, the movable brush 9061 uses the cable 912 to electrically connect the conductive slide rail 9053 on the corresponding side with the conductive sheet 9052. As the power socket 9024 is electrically connected to the conductive sheet 9052, the electricity is connected to the built-in coil of the electromagnet plate 9021, which can make the electromagnet plates 9021 in the current row be magnetically adsorbed to prevent the spread of iron filings.

[0075] After the movable brush 9061 is switched, the current iron filings will be processed by the subsequent cleaning brush 505 due to the release of the electromagnetic force.
