For example, a stainless steel coil slitting device with the patent publication number CN117324676A includes a machine case, two wall plates are connected to the machine case, a support frame is provided on one side of the machine case, a feeding roller is rotatably connected to the support frame, a roller assembly is rotatably connected to one side of the two wall plates, a bearing assembly is rotatably connected to the two wall plates near the roller assembly, a cutting roller is rotatably connected to the two wall plates, a cutting knife is connected to the cutting roller, a second motor for driving the cutting roller is provided outside one of the wall plates, a first guiding roller and a second guiding roller are provided below the front side of the bearing assembly on the two wall plates, a first winding roller and a second winding roller are rotatably connected to one end of the two wall plates away from the support frame, the first winding roller is located above the second winding roller, and a driving mechanism for driving the first winding roller and the second winding roller to rotate simultaneously is provided on the wall plate.

[0003] During the cutting process, the slitting device needs to perform staged cutting to ensure that the precision of the finished product width meets the requirements. However, during the slitting process, the current cutting piece will cut the two sides of the steel bar, resulting in a large amount of waste chips generated during continuous slitting. If not processed in time, the waste chips will accumulate at the cutting area, interfering with the precision of the cutting knife and causing the quality of the cut steel bar to decline.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. After the initial slitting, the excess coil materials on both sides will be guided downward by the falling roller, and the remaining coil materials will be further conveyed downward along with the limiting roller frame. By starting the adjustment motor, the positive and negative lead screws can be rotated. Under the threaded cooperation of the positive and negative lead screws and the sliding plates on both sides, the extension plates on both sides move relative to each other, thereby adjusting the support width of the current extension plate to cooperate with coil materials of different widths for support, and ensuring that the waste materials on both sides can be transferred downward. Finally, the waste materials on both sides will be deposited into the collection box under the guidance of the falling roller for easy later management.

[0016] 2. By starting the auxiliary motor to drive the third expansion shaft to rotate, a number of fixed rings are fixedly installed on the shaft body of the third expansion shaft, and each group of fixed rings is located on both sides of the adjacent combined cutting knives respectively. Combined with the cleaning brush provided on the surface of the turntable, the combined cutting knives and the electromagnetic iron plate at the current position can be cleaned. And at this position, the electromagnetic iron plate releases the magnetic attraction of the iron filings. Under the rotation guidance of the cleaning brush and in cooperation with the guiding cover, the iron filings are transferred to the collection port. Then, by continuously performing negative pressure treatment on the collection port by the guiding exhaust fan, the iron filings are accumulated in the collection bin to ensure that the iron filings will not fall to the contact position between the coil material and the cutting knife during continuous slitting, thereby ensuring the slitting quality during continuous slitting.

[0017] 3. By connecting the power connection panel to an external power source, the fixed electric brush can be electrically connected to the movable electric brush adjacent to the current position. The movable electric brush can be rotated and switched, thereby realizing the magnetic force control of each electromagnetic iron plate. After the movable electric brush receives power, the conductive slide rail on the corresponding side is electrically connected to the conductive sheet through a cable. As the power connection socket is electrically connected to the conductive sheet, the power is connected to the built-in coil of the electromagnetic iron plate, enabling the magnetic attraction of the current row of electromagnetic iron plates.

[0018] 4. By starting the control air pump to deliver gas, the gas will enter the converging tank through the pipeline, and then enter several extension channels from the converging tank respectively. Among them, the extension channels communicate with adjacent sealing grooves, so that the air pressure at the bottom of the adjacent sealing grooves increases. Through the sealing cooperation between the sealing grooves and the locking convex plates, the height of the locking convex plates rises, so as to cooperate with multiple locking convex plates to lock the placement seat for subsequent slitting operations. On the contrary, starting the control air pump to exhaust can make multiple locking convex plates descend to adjust the slitting distance of the placement seat to meet the slitting of coils with different widths.

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] As shown Figures 1 to 21 in the figure, an automatic slitting device for steel strip coils includes a first base 1. Inside the first base 1, a first expansion shaft 101 for storing the coil body 8 of the steel strip is installed through a feeding motor 102. On one side of the first base 1, a conveying table 2, a support table 3, and a second base 4 are sequentially installed. Inside the second base 4, a second expansion shaft 402 for winding the coil body 8 of the steel strip is installed through a winding motor 401. On the upper side of the second base 4, a guiding cover 5 is fixedly installed, and a slitting assembly 9 for precise slitting is installed inside the guiding cover 5.

[0023] The feeding motor 102 and the winding motor 401 can respectively drive the first expansion shaft 101 and the second expansion shaft 402 to rotate, so as to ensure that the steel strip coil can achieve stable conveying operation. The first expansion shaft 101 and the second expansion shaft 402 are used to store the steel strip coils at both ends.

[0024] In this application, a number of support rollers 201 are installed inside the conveying table 2, a number of pressing rollers 202 are arranged on the upper side of the conveying table 2, an extension frame 203 is fixedly installed on one side of the conveying table 2, and a slitting roller 2031 and a lifting roller 2032 are respectively rotatably installed on the upper and lower sides inside the extension frame 203; A second motor 7 is installed on the lower side of the conveying table 2. One end of the slitting roller 2031 and the lifting roller 2032 are respectively installed with meshing transmission gears 2033. A first pulley 2034 is installed outside one of the transmission gears 2033, and the second motor 7 is connected to the first pulley 2034 through a second track 701.

[0025] By starting the second motor 7 to drive the first pulley 2034 to rotate through the second track 701, one of the transmission gears 2033 is driven to rotate under the rotation of the first pulley 2034 and meshes with the other transmission gear 2033, so as to realize the relative rotation of the slitting roller 2031 and the lifting roller 2032, and thus the coil can be subjected to preliminary slitting treatment, so that the width of the coil initially meets the requirements. The pressing rollers 202 and the support rollers 201 can enhance the stability of the coil during conveying.

[0026] In this application, a chute 301 is opened on the surface of the support table 3. An extension plate 303 is movably installed inside the chute 301 through a sliding plate 3031. A collection box 302 for collecting waste materials on both sides is installed on the lower side of the support table 3. A group of falling rollers 305 are installed on both sides of the collection box 302 through bearing seats 304. A limiting roller frame 306 is fixedly installed on one side of the support table 3; An adjustment motor 3032 is fixedly installed on the lower side of the support table 3. The output end of the adjustment motor 3032 is fixedly installed with a positive and negative lead screw 3033, and the rod body of the positive and negative lead screw 3033 is threadedly matched with the sliding plates 3031 on both sides through penetration.

[0027] After the preliminary slitting is completed, the redundant coils on both sides will be guided downward by the falling roller 305, and the remaining coils will be further conveyed downward along with the limiting roller frame 306. By starting the adjusting motor 3032, the positive and negative lead screw 3033 can be rotated. Under the screw-thread fit between the positive and negative lead screw 3033 and the sliding plates 3031 on both sides, the extension plates 303 on both sides will move relatively, thereby adjusting the support width of the current extension plate 303 to support coils of different widths and ensuring that the waste materials on both sides can be transferred downward. Finally, the waste materials on both sides will be deposited into the collection box 302 under the guidance of the falling roller 305 for convenient later management.

[0028] In the present application, an installation frame 403 is fixedly installed on the upper side of the second base 4. A guiding cover 5 is fixedly installed on the upper side of the installation frame 403. A first motor 6 is fixedly installed on one side of the second base 4. An activity groove 404 is formed on one side of the second base 4. A tensioning roller 405 is movably installed inside the activity groove 404 through a spring.

[0029] To ensure that the coil can stably enter during winding by the second expansion shaft 402, the tensioning roller 405 supports the winding coil under the action of the spring to prevent the coil from loosening during further slitting. By starting the first motor 6, the first crawler 601 can be used to drive the second pulley 904 to rotate, thereby realizing the rotation of several combined cutting blades 9022 in the slitting assembly 9 and further precisely trimming both sides of the coil.

[0030] In this embodiment, an auxiliary motor 501 is fixedly installed on one side of the guiding cover 5. A third expansion shaft 502 is fixedly installed at the output end of the auxiliary motor 501. A number of fixing rings 503 are installed on the shaft body of the third expansion shaft 502. Every two fixing rings 503 are arranged oppositely. A turntable 504 is installed on the outer side of each fixing ring 503. A cleaning brush 505 is arranged on the surface of the turntable 504.

[0031] It should be noted that a collection bin 506 is fixedly installed on the lower side of the guiding cover 5. A collection port 5061 is arranged on the upper side of the collection bin 506. A discharge door 5062 is arranged on the outer side of the collection bin 506. A guiding exhaust fan 507 is fixedly installed on one side of the collection bin 506. The air inlet of the guiding exhaust fan 507 communicates with the inside of the collection bin 506 and the guiding cover 5. A filter screen is arranged at the air inlet of the guiding exhaust fan 507.

[0032] During the slitting process, the auxiliary motor 501 is started to drive the third expansion shaft 502 to rotate. A number of fixed rings 503 are fixedly installed on the shaft body of the third expansion shaft 502, and each group of fixed rings 503 is located on both sides of the adjacent combined cutting knives 9022. A cleaning brush 505 is arranged on the surface of the turntable 504, so that the combined cutting knives 9022 and the electromagnetic iron plate 9021 at the current position can be cleaned. At this position, the electromagnetic iron plate 9021 releases the magnetic attraction of the iron filings. Under the rotation guidance of the cleaning brush 505 and in cooperation with the guiding cover 5, the iron filings are transferred to the collection port 5061. Then, a guiding exhaust fan 507 continuously performs negative pressure treatment on the collection port 5061, so that the iron filings are accumulated in the collection bin 506, ensuring that the iron filings will not fall to the contact position between the coil and the cutting knife during continuous slitting, and thus ensuring the slitting quality during continuous slitting.

[0033] In this embodiment, the slitting assembly 9 includes a shaft body 901, which is rotatably installed inside the mounting frame 403. One end of the shaft body 901 is provided with a second pulley 904, and the output end of the first motor 6 is connected to the second pulley 904 through a first track 601. A number of sealing grooves 9051 are arranged on the surface of the shaft body 901, and locking convex plates 905 are arranged inside the sealing grooves 9051. A number of mounting seats 902 are installed on the shaft body of the shaft body 901, an electromagnetic iron plate 9021 is installed outside the mounting seat 902, and a combined cutting knife 9022 is installed outside a number of electromagnetic iron plates 9021 through a magnetic isolation ring 9023. In this application, the combined cutting knife 9022 is composed of two circular rings, and the magnetic isolation ring 9023 can be used to reduce the magnetic force of the electromagnetic iron plate 9021, avoiding the problem that the magnetic force of the electromagnetic iron plate 9021 interferes with the combined cutting knife 9022 during the magnetic attraction process, resulting in the adsorption of iron filings on the combined cutting knife 9022 and the inability to clean. The electromagnetic iron plates 9021 are arranged in groups, so as to ensure that the magnetic attraction of the electromagnetic iron plates 9021 can be controlled separately according to needs later, not only ensuring that the iron filings can be concentrated but also cooperating with the subsequent structure to realize the cleaning of the iron filings.

[0034] When specifically setting, a fixed frame 906 is installed at the other end of the shaft body 901, and a number of groups of movable electric brushes 9061 are arranged outside the fixed frame 906. A connecting seat 903 is fixedly installed on one side inside the mounting frame 403, and the connecting seat 903 is rotatably connected to the fixed frame 906; A power connection panel 9031 is installed outside the connecting seat 903, and a fixed electric brush 9032 is installed on one side of the inner wall of the connecting seat 903. The fixed electric brush 9032 is electrically connected to a number of groups of movable electric brushes 9061.

[0035] Among them, on one side of the inner wall of the sealing groove 9051, there is an installation groove 907. Inside the installation groove 907, a conductive slide rail 9053 is installed. Inside the locking convex plate 905, a conductive sheet 9052 is installed. The conductive sheet 9052 is electrically connected to the conductive slide rail 9053. At the bottom of the placement seat 902, there is a power connection socket 9024. The power connection socket 9024 is electrically connected to the conductive sheet 9052. The power connection socket 9024 is connected to the built-in coil of the electromagnetic iron plate 9021; On both sides of the installation groove 907, there are wire grooves 911. The conductive slide rail 9053 is electrically connected to the corresponding movable brush 9061 through a cable 912.

[0036] In order to achieve power transmission, it is connected to an external power source through the power connection panel 9031, so that the fixed brush 9032 can be electrically connected to the movable brush 9061 adjacent to the current position. Among them, the movable brush 9061 can be rotated and switched, so as to realize the magnetic force control of each electromagnetic iron plate 9021. When the movable brush 9061 is powered, the conductive slide rail 9053 on the corresponding side is electrically connected to the conductive sheet 9052 through the cable 912. As the power connection socket 9024 is electrically connected to the conductive sheet 9052, the power is connected to the built-in coil of the electromagnetic iron plate 9021, and the electromagnetic iron plates 9021 in the current row can perform magnetic adsorption.

[0037] In this application, a transfer ventilation pipe 910 is installed at the center of the fixed frame 906. On one side of the shaft body 901, there is a converging groove 908. Outside the converging groove 908, there are several extension channels 909. Each extension channel 909 communicates with the adjacent sealing groove 9051. On one side of the second base 4, a control air pump 10 is installed. The control air pump 10 is connected to the transfer ventilation pipe 910 through a pipeline. Inside the transfer ventilation pipe 910, there is an electromagnetic valve.

[0038] Among them, by starting the control air pump 10 to deliver gas, the gas will enter the converging groove 908 through the pipeline, and then enter several extension channels 909 respectively from the converging groove 908. By using the fact that the extension channels 909 communicate with the adjacent sealing grooves 9051, the air pressure at the bottom of the adjacent sealing grooves 9051 is increased. Through the sealing cooperation between the sealing groove 9051 and the locking convex plate 905, the height of the locking convex plate 905 rises, so as to cooperate with multiple locking convex plates 905 to lock the placement seat 902 for subsequent cutting operations. On the contrary, starting the control air pump 10 to exhaust can make multiple locking convex plates 905 descend to adjust the cutting distance of the placement seat 902 to meet the cutting of coils with different widths.

[0039] The working principle of this automatic steel strip coil cutting device: During use, first place the coil body 8 on the first expansion shaft 101, and draw one end of the coil body 8 into the second expansion shaft 402. Then, start the feeding motor 102 and the receiving motor 401 to drive the first expansion shaft 101 and the second expansion shaft 402 to rotate respectively, so as to ensure the stable conveying operation of the steel belt coil; Among them, by starting the second motor 7, the second crawler 701 is used to drive the first pulley 2034 to rotate. Under the rotation of the first pulley 2034, one of the transmission gears 2033 is driven to rotate and meshes with the other transmission gear 2033, so as to realize the relative rotation of the slitting roller 2031 and the lifting roller 2032, and thus the coil can be preliminarily slit. After the preliminary slitting is completed, the redundant coils on both sides will be guided downward under the action of the falling roller 305 and stored in the collection box 302 for later management; By starting the first motor 6, the first crawler 601 can be used to drive the second pulley 904 to rotate, and then the several combined cutters 9022 in the slitting assembly 9 can be rotated to further precisely trim the two sides of the coil; During the slitting process, by starting the auxiliary motor 501 to drive the third expansion shaft 502 to rotate, several 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 located on both sides of the adjacent combined cutter 9022 respectively. And the surface of the turntable 504 is provided with a cleaning brush 505, so as to clean the combined cutter 9022 and the electromagnetic iron plate 9021 at the current position. And at this position, the electromagnetic iron plate 9021 releases the magnetic attraction of the iron filings. Thus, under the rotation guidance of the cleaning brush 505 and in cooperation with the guiding cover 5, the iron filings are transferred to the collection port 5061. Then, the guiding suction fan 507 continuously performs negative pressure treatment on the collection port 5061, so as to accumulate the iron filings in the collection bin 506; During slitting, the shaft body 901 will continuously rotate, so as to frequently adjust the position of the movable electric brush 9061. Among them, through the power connection panel 9031 connected to the external power supply, the fixed electric brush 9032 can be electrically connected to the movable electric brush 9061 adjacent to the current position. The movable electric brush 9061 can rotate and switch, so as to realize the magnetic force control of each electromagnetic iron plate 9021. When the movable electric brush 9061 is powered on, the corresponding conductive slide rail 9053 and the conductive sheet 9052 are electrically connected through the cable 912. As the power connection socket 9024 is electrically connected to the conductive sheet 9052, the power is connected to the built-in coil of the electromagnetic iron plate 9021, so that the electromagnetic iron plates 9021 in the current row can perform magnetic adsorption to prevent the iron filings from spreading; After the movable electric 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.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
