Description

Technical Field

[0001] This invention relates to the field of amorphous nanoribbon slitting technology, and in particular to a novel amorphous nanoribbon slitting device. Background Technology

[0002] Amorphous nanoribbons are advanced functional metallic materials with an amorphous structure and nanoscale thickness, manufactured through a special process. Their most prominent advantages are extremely low magnetic loss and excellent soft magnetic properties under high-frequency conditions, making them one of the indispensable key materials driving the development of modern electronic devices towards high frequency, high efficiency, and miniaturization. Through slitting, various widths of ribbon can be obtained from a master roll of one width, greatly increasing the diversity of product specifications and application flexibility to meet the needs of different customers and products.

[0003] Currently, the slitting of amorphous nanoribbons is achieved by extruding the ribbon using a combination of roller cutters. The width of the high-plastic steel in the combination roller cutters is the required slitting width of the ribbon. During slitting, each slit branch of the ribbon needs to be individually wound by the grooves of the winding roller. The partitions between the grooves have thickness. After slitting, the cumulative thickness of these partitions limits the number of grooves that can be wound. Furthermore, the two outermost branches of the ribbon experience the largest deflection angle during winding, making them prone to tearing and breakage due to this deflection.

[0004] Therefore, a novel amorphous nanoribbon slitting device needs to be developed to solve the above problems. Summary of the Invention

[0005] This invention provides a novel amorphous nanoribbon slitting device to solve the defect in the prior art where the two outermost branches of the slitting strip have the largest deflection angle when wound up, and the edge branches are prone to tearing and damage due to deflection.

[0006] This invention provides a novel amorphous nanoribbon slitting device, comprising: a slitting section including two cooperating combined roller cutters, wherein the combined roller cutters are provided with slitting guide rollers along the strip conveying direction, and the slitting guide rollers are configured to keep the strip after being slitted by the combined roller cutters in a bundled state; a first winding assembly including at least two first winding wheels along the strip conveying direction, the first winding wheels being distributed along the strip conveying direction, and different first winding wheels being used to wind different slitted strips; and a second winding assembly including a winding base movable along the strip conveying direction, wherein a plurality of second winding wheels are provided beside the winding base, and the second winding assembly is configured to adjust the distance between the second winding wheels and the slitting guide rollers to change the winding angle of the strip after it has been slitted.

[0007] Furthermore, the novel amorphous nanoribbon slitting device also includes a frame, on both sides of the front end of the frame surface, a drive platform and an adjustment mechanism for use with the combined roller cutter, and the slitting guide roller is located between the drive platform and the adjustment mechanism.

[0008] Furthermore, the frame is provided with a filament collecting mechanism, which includes a filament collecting table located on the side of the slitting guide roller away from the combined roller cutter. The filament collecting table is fixedly connected to the frame. The frame is provided with a filament collecting roller on the side where the first winding roller is located. The filament collecting mechanism is configured such that the filament collecting table collects the filaments generated at the edge of the strip after slitting and then the filament collecting roller winds them up.

[0009] Furthermore, the adjustment mechanism includes a lead screw rotatably connected to the bottom of the side of the drive table where the slitting guide roller is located, and a sliding support frame is provided on the side of the combined roller cutter away from the drive table. The sliding support frame slides on a slide rail on the surface of the frame. The lead screw and the sliding support frame are threadedly connected. The adjustment mechanism is configured to rotate the lead screw to adjust the distance between the sliding support frame and the drive table according to the different lengths of the slitting guide roller.

[0010] Furthermore, the frame is provided with a number of evenly distributed guide rollers on one side of the first winding assembly, an operating table is fixedly connected to the surface of the frame, and a speed sensor is fixedly connected to the surface of the frame.

[0011] Furthermore, a guide rail is provided on one side of the frame where the second winding assembly is located, the winding base slides on the guide rail, and a positioning mechanism is provided between the winding base and the guide rail.

[0012] Furthermore, the positioning mechanism includes a plurality of evenly distributed positioning holes formed on the surface of the guide rail. Mounting plates are fixedly connected to both sides of the winding base along the conveying direction of the strip. The mounting plates have slots that mate with the positioning holes, and positioning bolts that mate with the positioning holes are provided in the slots of the mounting plates.

[0013] Furthermore, the second winding wheel winds up a greater number of rolls than the first winding wheel, and the second winding wheel is used to simultaneously wind up multiple strips to be slit.

[0014] The present invention provides a novel amorphous nanoribbon slitting device, which has the following technical effects or advantages: 1. The winding platform in the second winding assembly guides the strip along the conveying direction on the guide rail, away from the frame. After the strip is slit, the deflection angle of the two outermost branch strips is reduced, making it easier to use the second winding wheel to wind up the amorphous nanoribbon that has been slit into more branch strips. This reduces tearing caused by excessive number of branch strips during winding, ensuring the integrity of the strip during winding.

[0015] 2. The strip is cut into several branch strips according to the required width by the extrusion of the combined roller cutter. The branch strips are wound up by the corresponding grooves of the winding wheel. The first winding assembly is used to simultaneously wind up multiple strips after they have been cut, thereby improving the strip cutting efficiency. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] As mentioned above, in existing strip slitting devices, the two outermost branches of the strip have the largest deflection angle when they are wound up after the strip is slit. The outermost branches are prone to tearing and damage due to deflection.

[0021] To address this, the present invention provides a novel amorphous nanoribbon slitting device, which can slit the ribbon through the extrusion of the combined roller cutter 4. The ribbon is slitted into several branch ribbons according to the required width. The branch ribbons are wound up by the corresponding grooves of the winding wheel. The first winding assembly 2 is used to simultaneously wind up multiple ribbons after slitting, thereby improving the slitting efficiency of the ribbon. Using the winding base 301 in the second winding assembly 3, the strip is guided along the conveying direction on the guide rail 13, away from the frame 6. After the strip is slit, the deflection angle of the two outermost branch strips is reduced, which facilitates the use of the second winding wheel 302 to wind up the amorphous nanoribbon that has been slit into more branch strips. This reduces tearing caused by deflection during strip winding due to an excessive number of branch strips, ensuring the integrity of the strip during winding.

[0022] The following is combined Figures 1-5 This invention is described in detail.

[0023] First embodiment: like Figures 1-5 As shown, the present invention provides a slitting device, particularly a novel amorphous nanoribbon slitting device. In this embodiment, the slitting device mainly includes a frame 6 that is L-shaped when viewed from above. On the upper surface of the frame 6, along the conveying direction of the ribbon, a slitting section 1, a first winding assembly 2, and a second winding assembly 3 are sequentially arranged. The slitting section 1 includes a combination of combined rollers 4 and slitting rollers 5. The combined rollers 4 are composed of, for example, high-plastic steel and rubber pads arranged in an alternating pattern. The high-plastic steel and rubber pads in the upper and lower combined rollers 4 are interleaved. By the mutual compression of the two combined rollers 4, the high-plastic steel sheet in the upper combined roller 4 compresses the rubber pad in the lower combined roller 4. The same applies to the lower combined roller 4. The high-plastic steel on the two combined rollers 4 forms a shear, slitting the amorphous nanoribbon passing between the two combined rollers 4, changing the width of the ribbon, and then conveying it for separate winding.

[0024] like Figures 1-3As shown, the strip material, after being slit by the combined roller cutter 4, passes through the slitting guide roller 5 and moves backward. The slitting guide roller 5 is used to keep the strip material in a concentrated state after being slit by the combined roller cutter 4, reducing the deflection of the strip material after slitting, which affects the slitting process, and reducing the tearing caused by the slitting of the strip material on the un-slitting strip material. To ensure that the strip material is slit only by the combined roller cutter 4, a drive platform 7 is fixedly connected to one side of the combined roller cutter 4 on the surface of the frame 6. The shaft at one end of the combined roller cutter 4 is detachably connected to the output end of the drive platform 7. An adjustment mechanism 8 is set on the surface of the frame 6 on the side of the combined roller cutter 4 away from the drive platform 7. The adjustment mechanism 8 includes a lead screw 801 and a sliding support frame 802. The sliding support frame 802 can slide on the frame 6, moving closer to or away from the drive platform 7. Different lengths of combined roller cutters 4 are selected according to the required width of the strip material to be slit or the number of strip materials to be slit simultaneously.

[0025] like Figures 1-3 As shown, a first winding assembly 2 is provided on the side of the frame 6 near the sliding support frame 802. The first winding assembly 2 includes at least two first winding wheels 201 rotatably connected to the side of the frame 6, for example, two winding wheels. The two winding wheels 201 can wind up the branch strips after the two strips have been cut. In order to wind up the branch strips after the cut strips are cut up separately, partitions are provided on the winding wheels to separate the branch strips between each adjacent branch strip. Since the partitions have thickness, the two branch strips at the outermost edge of the strip have the largest deflection angle from the strip conveying direction during the winding process, and the strip is most likely to tear due to deflection.

[0026] After the strip is cut, excess ribbons are easily generated at the edges. To prevent these excess ribbons from tangling or affecting the normal winding of the remaining strip, a ribbon collecting mechanism 9 is installed on the frame 6. The ribbon collecting mechanism 9 includes a ribbon collecting table 901 fixedly connected to the side of the frame 6 near the first winding wheel 201 at the corner, and a ribbon collecting roller 902 installed on the side of the frame 6 where the first winding wheel 201 is located. The ribbon collecting roller 902 is used to wind up the ribbons guided and collected by the ribbon collecting table 901. The frame 6 is equipped with the same number of guide rollers 10 as the winding wheels. The guide rollers 10 are used to guide different strips to the corresponding winding wheels, facilitating the winding wheels to wind up the cut strips. A PLC control system is installed on the surface of the frame 6 to control the rotation of the winding wheel, guide roller 10, and slitting section 1. A speed sensor 12 is also installed on the surface of the frame 6 to measure the speed of the strip conveyed at the slitting guide roller 5. This allows for the adjustment of the rotation speed of the guide roller 10 and the winding wheel based on the conveying speed of the strip at the slitting guide roller 5, so as to rewind the slitting branch strip.

[0027] For example, if the strip is divided into four sections and the thickness of the divider on the take-up roller is d, then the deflection angle of the two outermost branches is θ1. The distance from the cutting point of the strip after it is cut by the cutting guide roller 5 to the shaft of the take-up roller is L1. At this time, tanθ1=3d / 2L1, so θ1=arctan(3d / 2L1), where y=arctan(x) is an increasing function, and the larger x is, the larger y is.

[0028] In practical use, the amorphous nanoribbon to be cut is fed backward through the unwinding device, with one end of the ribbon passing between the combined roller cutters 4. After being cut by the combined roller cutters 4, the cut ribbon is bundled by the slitting guide roller 5. Under the guidance of the guide roller 10, the ribbon is wound onto the first take-up roller 201 at the corresponding position. The number of rolls wound by the first take-up roller 201 is the same as the number of ribbons in the corresponding branch that have been cut. If the combined roller cutters 4 are used to cut two ribbons at the same time, two first take-up rollers 201 are required to simultaneously wind up the ribbons. The central axis of the ribbon is aligned with the middle position of the corresponding take-up roller, and the deflection angle of the two ribbons at the edge of the cut is the largest.

[0029] Second embodiment: Based on the first embodiment, the present invention can also be used to wind up the strip when it is slit into more branch strips. Since multiple winding grooves on the winding wheel wind up several branch strips that have been slit, and the grooves on the winding wheel are separated by partitions, the more branch strips are wound up, the greater the deflection angle of the two edge branch strips during winding. The edge branch strips are more prone to tearing and damage. For example, if the slit strip is divided into six strips and the thickness of the partition on the winding wheel is d, then the deflection angle of the two outermost branch strips is θ2. The distance from the slit point of the strip after being slit by the slit guide roller 5 to the shaft of the winding wheel is L2. At this time, tanθ2 = 5d / 2L2, so θ2 = arctan(5d / 2L2). If L2 = L1, then θ2 is greater than θ1, and the two edge strips are more prone to tearing and breaking due to deflection.

[0030] Therefore, in this embodiment, two guide rails 13 and a second winding assembly 3 are installed on the ground on the side of the frame 6 away from the strip unwinding device. The second winding assembly 3 includes a winding base 301 mounted on the guide rails 13, which can move along the strip conveying direction. At least two second winding wheels 302 are mounted on the winding base 301 on the same side of the frame 6 as the first winding wheel 201. The second winding wheels 302 are driven by a drive mechanism within the winding base 301. The second winding assembly 3 is connected to the operating table 11 system on the frame 6 to ensure that, similarly to the first winding assembly 2, its winding speed is consistent with the strip unwinding speed. To reduce the aforementioned θ2, L2 can be increased to reduce the deflection angle of the edge strip. The adjustment method is as follows: Figure 4 and Figure 5 The winding base 301 is moved along the guide rail 13 away from the frame 6. Several pairs of strip support, guide, or transmission devices can be installed between the frame 6 and the winding base 301 to ensure the transmission and support of the strip. The deflection angle of the edge branch strip is as follows: Figure 5 The transformation from α to β in the medium gradually decreases. To fix the movable take-up base 301 and prevent it from moving during the winding of the strip, mounting plates 1402 are fixedly connected to the front, back, and sides of the bottom of the take-up base 301. The surface of the mounting plates 1402 is provided with slots, and several evenly distributed positioning holes 1401 are provided on the surface of the guide rail 13. Positioning bolts 1403 are provided on the mounting plates 1402. The positioning bolts 1403 pass through the mounting plates 1402 and are inserted into the positioning holes 1401 of the guide rail 13 to complete the positioning of the take-up base 301.

[0031] In summary, the novel amorphous nanoribbon slitting device of the present invention has the following advantages: 1. After slitting, the amorphous nanoribbon is slitted by the extrusion of the combined roller cutter 4. The ribbon is slitted into several branch ribbons according to the required width. The branch ribbons are wound up by the corresponding groove of the winding wheel. The first winding assembly 2 is used to simultaneously wind up multiple ribbons after slitting, thereby improving the slitting efficiency of the ribbon.

[0032] Second, utilizing the winding base 301 in the second winding assembly 3, along the conveying direction of the strip on the guide rail 13, away from the frame 6, the deflection angle of the two outermost branch strips after the strip is slit is reduced. This facilitates the use of the second winding wheel 302 to wind up the amorphous nanoribbon that has been slit into more branch strips. This reduces tearing caused by excessive number of branch strips during winding, ensuring the integrity of the strip during winding.

[0033] The PLC control system used to control the motor rotation and the speed sensor used to measure the speed in the equipment are existing technologies, common knowledge in the field, and are not part of the improvement technology in this case, so they will not be described in detail here.
