Description

Technical Field

[0001] This utility model relates to the field of fiber processing equipment technology, specifically a high-strength fiber shearing device. Background Technology

[0002] High-strength fibers (such as carbon fiber, aramid fiber, and ultra-high molecular weight polyethylene fiber) have been widely used in aerospace, high-end equipment manufacturing, new energy, and building materials due to their excellent properties such as high strength, high modulus, acid and alkali resistance, and resistance to high and low temperatures. In the processing of high-strength fibers, depending on product requirements (such as making fiber cloth, fiberboard, fiber rod, etc.), they need to be cut into specifications of specific lengths or widths. This process places stringent requirements on the performance of shearing equipment—it must not only overcome the extremely high shear strength of the high-strength fibers themselves, but also ensure that the sheared surface is flat and free from "fraying" or "chipping".

[0003] However, current shearing equipment for high-strength fibers still has many technical challenges in practical applications:

[0004] Firstly, the problem of insufficient shear force is prominent. Traditional shearing equipment mostly adopts single lever drive or direct hydraulic rod drive. Due to structural limitations, the shear force amplification factor is limited (usually only 1-2 times). When facing high-strength fibers with high shear strength (such as aerospace-grade carbon fiber prepreg), problems such as "incomplete fiber breakage" and "edge fraying" often occur due to insufficient shear force.

[0005] Secondly, the poor adaptability of the conveying structure easily causes fiber damage. The existing equipment's conveying system is mostly a fixed structure, and the distance between the conveying roller and the shearing platform cannot be flexibly adjusted. If the fixed distance is too large, it will easily cause wrinkling and deviation during fiber conveying; for multi-layered thick materials, if the distance is too small, it will cause scratch damage to the fiber surface due to excessive conveying pressure (especially for high-strength fibers with surface coatings).

[0006] In summary, the current shortcomings of high-strength fiber shearing equipment in terms of shearing force and conveying adaptability have become key bottlenecks restricting the processing efficiency and product quality of high-strength fibers. There is an urgent need to develop a new type of shearing equipment that can effectively amplify shearing force and flexibly adapt to fibers of various specifications. Utility Model Content

[0007] The purpose of this invention is to provide a high-strength fiber shearing device that solves the technical problems of traditional shearing devices for high-strength fibers (such as carbon fiber and aramid fiber) that are caused by insufficient shearing force, resulting in "fragmentation" and "incomplete breakage". It also addresses the issues of shearing blade tilting and low shearing accuracy caused by single-lever drive, as well as the fixed conveying structure that cannot adapt to fibers of different thicknesses and is prone to fiber damage. The invention effectively amplifies the shearing force to adapt to the high shear resistance of high-strength fibers, ensures stable and synchronous operation of the shearing blades, and enables flexible adjustment of the conveying structure to accommodate multiple fiber specifications.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-strength fiber shearing device, comprising a shearing platform, a conveyor roller lifting and adjusting part, and a shearing lever force-increasing part; a guide platform is fixedly installed on one outer wall of the shearing platform; the conveyor roller lifting and adjusting part is located at the top of the shearing platform; and the shearing lever force-increasing part is located at the top of the shearing platform.

[0009] Preferably, the conveyor roller lifting and adjusting unit specifically includes: an input conveyor belt, disposed on the shearing platform; a shearing pad, disposed on the shearing platform; an output conveyor belt, disposed on the shearing platform; and a shearing protective shell, fixedly installed on the top outer wall of the shearing platform.

[0010] Preferably, a control panel is fixedly installed on the outer wall of the shear protection shell, a transparent through window is provided on one side of the outer wall of the shear protection shell, a positioning sleeve is fixedly installed on the top outer wall of the shear protection shell, an electric telescopic rod is fixedly installed inside the positioning sleeve, and a rectangular sliding groove is opened inside the shear protection shell.

[0011] Preferably, the top outer wall of the shear protection shell is symmetrically provided with rectangular guide grooves, which are adapted to rectangular sliding grooves. The telescopic end of the electric telescopic rod moves through the top outer wall of the shear protection shell and extends into the interior of the rectangular sliding groove. The telescopic end of the electric telescopic rod is fixedly connected to a lifting frame, and rectangular guide slide plates are symmetrically fixedly installed on the top outer wall of the lifting frame.

[0012] An electric telescopic rod is installed and fixed in the positioning sleeve at the top of the shear protective shell. Its telescopic end is directly connected to the lifting frame that carries the conveyor roller. The lifting frame forms a sliding fit with the rectangular guide groove of the protective shell through a rectangular guide plate. With this structure, the electric telescopic rod can drive the lifting frame to move up and down stably along the guide groove through its telescopic movement, thereby driving the conveyor roller to move up and down synchronously, so as to realize the control of the vertical position of the conveyor roller.

[0013] Preferably, the rectangular guide slide plate is adapted to the rectangular guide groove, the other end of the rectangular guide slide plate extends to the outer wall of the shear protection shell through the rectangular guide groove, a limit plate is fixedly installed at the other end of the rectangular guide slide plate, and a drive motor is fixedly installed on the outer wall of the lifting frame.

[0014] Preferably, the output end of the drive motor is fixedly connected to a rotating shaft, the other end of the rotating shaft movably passes through the outer wall of the lifting frame and extends into the interior of the lifting frame, the other end of the rotating shaft is rotatably connected to the inner wall of the lifting frame, and a conveying roller is fixedly sleeved on the outer wall of the rotating shaft.

[0015] Preferably, the shear lever force-enhancing part specifically includes: a mounting plate, fixedly installed between the inner walls of the shear protective shell; a shear blade, disposed inside the shear protective shell; a fixing plate is fixedly installed on one side of the outer wall of the mounting plate, a shaft is provided on the fixing plate, positioning shafts are symmetrically fixedly installed on the outer wall of the mounting plate, lever one and lever two are respectively movably sleeved on the outer wall of the positioning shaft, a pin one is provided at one end of lever one, and a pin two is provided at the other end of both lever one and lever two, and a bushing is movably sleeved on the outer wall of the shaft.

[0016] Lever 1 and Lever 2 are designed. High-strength fibers (such as carbon fiber and aramid fiber) have high strength and high toughness. Conventional shearing structures are prone to problems such as "insufficient shearing force leading to fiber pulling and uneven cuts." Lever 1 and Lever 2 form a double-lever linkage force-enhancing structure with a positioning shaft as the fulcrum: when the hydraulic telescopic rod drives lever 1 to rotate through the connecting sleeve and pin, lever 1 amplifies the hydraulic driving force with the help of the positioning shaft as the fulcrum. At the same time, it drives lever 2 to rotate symmetrically through the transverse linkage lever. The power of the two sets of levers is transmitted to both ends of the shearing blade through their respective connecting levers. This design of simultaneous force exertion by the double levers can amplify the shearing force by 3-5 times compared to a single lever. This ensures that even when facing high-strength fiber bundles with large diameters and extremely high toughness, instantaneous cutting can be achieved, avoiding fiber stretching deformation or rough cuts due to insufficient force, and improving the shearing quality.

[0017] Preferably, a hydraulic telescopic rod is fixedly installed on one outer wall of the bushing, and a connecting sleeve is fixedly connected to the telescopic end of the hydraulic telescopic rod. The connecting sleeve is movably connected to lever one via pin one. Both lever one and lever two are movably connected to connecting levers via pin two. Connecting shafts are symmetrically fixedly installed on the shearing blade. The connecting levers are movably connected to the shearing blade via the connecting shafts. Lateral linkage levers are provided on both outer walls of the connecting levers, and both ends of the lateral linkage levers are movably sleeved on the outer wall of pin two.

[0018] A hydraulic telescopic rod is installed, which, in combination with two levers (lever one and lever two), constructs a "multi-stage lever force amplification structure": the extension and retraction power of the hydraulic telescopic rod is first transmitted to one end of lever one through the connecting sleeve and pin one, and then amplified and transmitted to the other end of lever one with the positioning shaft as the fulcrum; at the same time, the lateral linkage lever synchronously drives lever two to move synchronously, so that the power of the two levers acts on the shearing blade through pin two and connecting lever. This combination method can amplify the output force of the hydraulic telescopic rod by 3-5 times, so that even when facing the high shear strength of high-strength fibers (such as carbon fiber, aramid fiber, etc.), instantaneous and stable shearing can be achieved, avoiding problems such as "fragmentation" and "incomplete breakage" of fibers due to insufficient shearing force.

[0019] This invention provides a high-strength fiber shearing device. It has the following beneficial effects:

[0020] (1) This utility model uses an electric telescopic rod to drive the lifting frame to drive the conveying roller to achieve up and down lifting. The height of the conveying roller can be flexibly adjusted according to the actual thickness of the high-strength fiber. Slight pressure is used to ensure that the fiber is conveyed flat and to avoid the fiber from running off track due to excessive gaps. For thick materials with multiple layers, the conveying roller can be raised to reserve sufficient feeding space. At the same time, the pressure of the conveying roller is used to compact the stacked fibers to prevent the layers from sliding during shearing.

[0021] (2) This utility model constructs a multi-stage force amplification structure by using a shear lever force amplification part with "hydraulic telescopic rod + double lever + connecting lever" to achieve efficient amplification of shearing force: the power output by the hydraulic telescopic rod is first transmitted to lever one through the connecting sleeve and pin shaft, and the power is initially amplified by using the lever principle with the positioning shaft as the fulcrum; at the same time, the transverse linkage lever synchronously drives lever two to work together with lever one, so that the amplified power of the double lever is collected to the connecting lever through pin shaft two, and the connecting lever further transmits the power to the shearing blade.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example 1:

[0030] Based on the existing problems of traditional shearing equipment for high-strength fibers (such as carbon fiber and aramid fiber) where insufficient shearing force leads to "fiber pulling" and "incomplete breakage," as well as the issues of blade tilting and low shearing accuracy caused by single-lever drive, and the inability of fixed conveying structures to adapt to fibers of different thicknesses, which easily cause fiber damage, the present invention provides a preferred embodiment of a high-strength fiber shearing device, for example... Figure 1-4 As shown: A high-strength fiber shearing device includes a shearing platform 1, a conveyor roller lifting and adjusting part 3, and a shearing lever force increasing part 4. A guide platform 2 is fixedly installed on one outer wall of the shearing platform 1; the conveyor roller lifting and adjusting part 3 is located on the top of the shearing platform 1; and the shearing lever force increasing part 4 is located on the top of the shearing platform 1.

[0031] The conveyor roller lifting adjustment unit 3 specifically includes: an input conveyor belt 311, which is set on the shearing platform 1; a shearing pad 312, which is set on the shearing platform 1; an output conveyor belt 313, which is set on the shearing platform 1; and a shearing protective shell 314, which is fixedly installed on the top outer wall of the shearing platform 1.

[0032] A control panel 315 is fixedly installed on the outer wall of the shear protection shell 314. A transparent through window is provided on one side of the outer wall of the shear protection shell 314. A positioning sleeve is fixedly installed on the top outer wall of the shear protection shell 314. An electric telescopic rod 317 is fixedly installed inside the positioning sleeve. A rectangular sliding groove 316 is opened inside the shear protection shell 314.

[0033] The top outer wall of the shear protection shell 314 is symmetrically provided with rectangular guide grooves 318, which are adapted to the rectangular slide groove 316. The telescopic end of the electric telescopic rod 317 moves through the top outer wall of the shear protection shell 314 and extends into the interior of the rectangular slide groove 316. The telescopic end of the electric telescopic rod 317 is fixedly connected to a lifting frame 3111, and rectangular guide slide plates 319 are symmetrically fixedly installed on the top outer wall of the lifting frame 3111.

[0034] The rectangular guide slide plate 319 is adapted to the rectangular guide groove 318. The other end of the rectangular guide slide plate 319 extends to the outer wall of the shear protection shell 314 through the rectangular guide groove 318. The other end of the rectangular guide slide plate 319 is fixedly installed with a limit circular plate. The outer wall of the lifting frame 3111 is fixedly installed with a drive motor 3113.

[0035] The output end of the drive motor 3113 is fixedly connected to a rotating shaft. The other end of the rotating shaft passes through the outer wall of the lifting frame 3111 and extends into the interior of the lifting frame 3111. The other end of the rotating shaft is rotatably connected to the inner wall of the lifting frame 3111. A conveying roller 3112 is fixedly sleeved on the outer wall of the rotating shaft.

[0036] Furthermore, in this embodiment, high-strength fibers, such as carbon fiber cloth or aramid fiberboard, are laid flat at one end on the guide platform 2 on one side of the shearing platform 1. The inclined guide surface of the guide platform 2 guides the fibers to the surface of the input conveyor belt 311, ensuring that the fiber edges are aligned with the side of the conveyor belt to prevent deviation. The input conveyor belt 311 is started, and the fibers are conveyed into the equipment at a uniform speed. When the fiber tip reaches below the conveyor roller 3112 inside the shearing protective shell 314, the drive motor 3113 drives the rotating shaft to drive the conveyor roller 3112 to rotate synchronously. Combined with the conveying force of the input conveyor belt 311, the fibers are smoothly pressed against the surface of the shearing pad 312, forming a continuous conveying state of "input-pressing-guiding". During the conveying process, the rectangular guide slide plate 319 at the top of the lifting frame 3111 follows the rectangular guide groove 3 of the shearing protective shell 314. 18. Maintain stability and ensure that the conveyor roller 3112 does not tilt. The fiber always moves in a flat state directly above the shearing pad 312 in the shearing area. The lifting frame is driven by an electric telescopic rod to move the conveyor roller up and down. The height of the conveyor roller can be flexibly adjusted according to the actual thickness of the high-strength fiber. Slight pressure is used to ensure that the fiber is conveyed flat and to avoid fiber deviation due to excessive gaps. For thick materials with multiple layers, the conveyor roller can be raised to reserve sufficient feeding space. At the same time, the pressure of the conveyor roller is used to compact the stacked fibers to prevent interlayer slippage during shearing.

[0037] Example 2:

[0038] Based on Embodiment 1, a preferred embodiment of the high-strength fiber shearing device provided by this utility model is as follows: Figure 1-4 As shown: The shear lever force-enhancing part 4 specifically includes: a mounting plate 411, which is fixedly installed between the inner walls of the shear protective shell 314; a shear blade 4116, which is disposed inside the shear protective shell 314; a fixing plate 412 is fixedly installed on one side of the outer wall of the mounting plate 411, and a shaft 413 is provided on the fixing plate 412; positioning shafts 4112 are symmetrically fixedly installed on the outer wall of the mounting plate 411; lever one 416 and lever two 417 are respectively movably sleeved on the outer wall of the positioning shafts 4112; a pin 419 is provided at one end of lever one 416; and pins 4111 are provided at the other ends of both lever one 416 and lever two 417; and a bushing 414 is movably sleeved on the outer wall of the shaft 413.

[0039] A hydraulic telescopic rod 418 is fixedly installed on one outer wall of the bushing 414. The telescopic end of the hydraulic telescopic rod 418 is fixedly connected to a connecting sleeve 415. The connecting sleeve 415 is movably connected to a lever 416 via a pin 419. Both lever 416 and lever 417 are movably connected to a connecting lever 4114 via a pin 4111. A connecting shaft 4115 is symmetrically fixedly installed on the shearing blade 4116. The connecting lever 4114 is movably connected to the shearing blade 4116 via the connecting shaft 4115. A transverse linkage lever 4113 is provided on both outer walls of the connecting lever 4114. Both ends of the transverse linkage lever 4113 are movably sleeved on the outer wall of the pin 4111.

[0040] Furthermore, in this embodiment, when the high-strength fiber tip is delivered to the shearing position directly above the shearing pad 312, the control panel 315 issues a shearing command. The hydraulic telescopic rod 418 in the shearing lever force-enhancing part 4 is activated and extends downward. Its telescopic end drives the lever 416 to swing downward around the positioning shaft 4112 via the connecting sleeve 415 and the first pin 419. At the same time, the transverse linkage lever 4113 pulls the second lever 417 to swing in the same direction around the other positioning shaft 4112 in sync with the swing of the first lever 416, realizing the synchronous action of the two levers. The other end of the two levers drives the connecting lever 4114 to move downward via the second pin 4111. The connecting lever 4114 drives the shearing blade 4116 to move vertically downward via the connecting shaft 4115 on the shearing blade 4116. Under the force amplification effect of the double levers, the hydraulic telescopic rod 418 amplifies the power by 3-5 times to stabilize the pressure on the high-strength fibers on the surface of the shearing pad 312, instantly completing the shearing. During the shearing process, the shearing blade 4116 remains parallel to the shearing pad 312 due to the synchronous constraint of the transverse linkage lever 4113, ensuring that the fiber shearing surface is flat and without bevels, achieving efficient amplification of shearing force. The power output by the hydraulic telescopic rod is first transmitted to lever one through the connecting sleeve and pin, and the power is initially amplified using the lever principle with the positioning shaft as the fulcrum. At the same time, the transverse linkage lever synchronously drives lever two to work in tandem with lever one, so that the amplified power of the double levers is collected to the connecting lever through pin two, and the connecting lever further transmits the power to the shearing blade.

[0041] Working principle:

[0042] Step 1: The operator starts the equipment through the control panel 315 on the outer wall of the shearing protective shell 314, completes the power-on self-test of core components such as the power supply, drive motor 3113, and hydraulic telescopic rod 418, and ensures that there are no fault indications for each component. According to the thickness of the high-strength fiber to be sheared, the operator sets key parameters through the control panel 315: for the conveyor roller lifting adjustment part 3, the operator sets the extension stroke of the electric telescopic rod 317 and determines the distance between the conveyor roller 3112 and the shearing pad 312 on the shearing platform 1 to ensure that the fiber can pass through smoothly without slipping; for the shearing lever force enhancement part 4, the operator sets the output pressure and extension speed of the hydraulic telescopic rod 418 to control the shearing rhythm; and sets the synchronous running speed of the input conveyor belt 311, output conveyor belt 313, and conveyor roller 3112.

[0043] Step 2: Lay one end of a high-strength fiber, such as carbon fiber cloth or aramid fiber board, flat on the guide platform 2 on one side of the shearing platform 1. Guide the fiber to the surface of the input conveyor belt 311 through the inclined guide surface of the guide platform 2, ensuring that the fiber edge is aligned with the side of the conveyor belt to avoid deviation. Start the input conveyor belt 311, and the fiber is conveyed into the equipment at a uniform speed with the conveyor belt. When the fiber tip reaches below the conveyor roller 3112 inside the shearing protective shell 314, the drive motor 3113 drives the rotating shaft to drive the conveyor roller 3112 to rotate synchronously. Combined with the conveying force of the input conveyor belt 311, the fiber is smoothly pressed against the surface of the shearing pad 312, forming a continuous conveying state of "input-pressing-guiding". During the conveying process, the rectangular guide slide plate 319 at the top of the lifting frame 3111 remains stable along the rectangular guide groove 318 of the shearing protective shell 314, ensuring that the conveyor roller 3112 does not tilt and the fiber always moves flat towards the shearing pad 312 in the shearing area.

[0044] Step 3: When the high-strength fiber tip is conveyed to the shearing position directly above the shearing pad 312, the control panel 315 issues a shearing command. The hydraulic telescopic rod 418 in the shearing lever force-enhancing section 4 starts and extends downward. Its telescopic end drives the lever 416 to swing downward around the positioning shaft 4112 through the connecting sleeve 415 and the first pin 419. At the same time, the transverse linkage lever 4113 pulls the second lever 417 to swing in the same direction around the other positioning shaft 4112 in sync with the swing of the first lever 416, realizing the synchronous action of the two levers; the other end of the two levers is connected by the second pin 4111. The moving connecting lever 4114 moves downward. The connecting lever 4114 drives the shearing blade 4116 to move vertically downward through the connecting shaft 4115 on the shearing blade 4116. Under the force amplification effect of the double levers, the hydraulic telescopic rod 418 amplifies the power of the shearing blade 4116 by 3-5 times to stabilize the pressure on the high-strength fiber on the surface of the shearing pad 312, and completes the shearing instantly. During the shearing process, the shearing blade 4116 remains parallel to the shearing pad 312 due to the synchronous constraint of the transverse linkage lever 4113, ensuring that the fiber shearing surface is flat and without bevels.

[0045] Step 4: After shearing is completed, the hydraulic telescopic rod 418 extends and retracts upward to reset, driving the shearing blade 4116 back to the initial hovering position through the lever system; at the same time, the input conveyor belt 311, the conveying roller 3112 and the output conveyor belt 313 restart synchronously, conveying the sheared high-strength fiber segments on the shearing pad 312 to the output conveyor belt 313, and the output conveyor belt conveys the finished product to the receiving device guide table 2 outside the equipment. The subsequent unsheared high-strength fibers continue to be conveyed to the shearing area with the input conveyor belt 311, repeating the "positioning-shearing-conveying" process of steps three to five to achieve continuous shearing operation; the operator can observe the internal shearing status in real time through the transparent through window of the shearing protective shell 314, and if parameters need to be adjusted, they can be corrected at any time through the control panel 315.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
