Description

Technical Field

[0001] The present application relates to the technical field of composite material processing, and in particular to a polymer rib surface processing device and a weaving method. Background Art

[0002] At present, fiber reinforced polymer (FRP) bars are a new type of material formed by continuous fiber reinforced resin matrix, which is lightweight, high-strength, corrosion-resistant, fatigue-resistant and non-magnetic.

[0003] In order to improve the bonding performance between FRP bars and concrete, the following measures are often used to process the surface of FRP bars: (1) Directly process the surface of FRP bars by mechanical methods; (2) Use a traction chain to press corrugations on the surface of FRP bars to make the surface appear as threads or indentations; (3) Let the FRP bars pass through a die with a concave and convex inner surface to form concave and convex surfaces; (4) Cover the surface of FRP bars with granular materials (adhesive sand) or short fibers. The surface of FRP bars formed by pultrusion is usually a ribbed surface formed by a winding process. Through a large number of experimental studies, it is found that when the FRP bars under this surface are damaged, the cracks can easily spread along the fiber winding direction, resulting in a significant decrease in the transverse modulus of the FRP bars. In addition, the bonding performance of this surface with concrete is poor, and the FRP bars are easily pulled out of the concrete, which cannot effectively play the advantages of FRP bars.

[0066] Refer to the following Figures 1 to 11The present invention describes a polymer tendon surface processing device and a weaving method according to embodiments of the present application.

[0067] See also Figures 1 to 11 As shown, an embodiment of the present application provides a polymer tendon surface processing device, which includes a fixed component, a rotating component and a core rod 13 as a processing target. The core rod 13 is passed through the fixed component, and the rotating component is rotatably set on the fixed component. At least one yarn wheel 9 is provided on the rotating component, and a fiber bundle is wound on the yarn wheel 9. The free end of the fiber bundle is fixed to the core rod 13. As the rotating component rotates, the fiber bundle on the yarn wheel 9 is gradually wound onto the core rod 13, and a woven layer with a concave-convex structure is formed on the surface of the core rod 13. The core rod 13 with a complete woven layer after weaving is a preformed rod 14.

[0068] Specifically, the number of rotating members is preferably two, namely a first rotating member and a second rotating member, wherein the first rotating member and the second rotating member are both rotatably mounted on a fixed member, and a core rod 13 extends toward the first rotating member and the second rotating member. The first rotating member and the second rotating member are respectively provided with a plurality of yarn wheels 9, and the free ends of the fiber bundles on the plurality of yarn wheels 9 are wound one by one onto the core rod 13. When the first rotating member and the second rotating member begin to rotate, the yarn bundles on the yarn wheels 9 are wound onto the core rod 13, forming an uneven braided layer on the core rod 13. Preferably, the first rotating member and the second rotating member rotate in opposite directions, so that the adjacent fiber bundles wound onto the core rod 13 are arranged crosswise.

[0069] Furthermore, the fixing component includes: a fixing seat 10, a support rod 8 and a fixing tube 2, the number of the support rod 8 is at least one, one end of each support rod 8 is connected to the fixing seat 10, and the other end of each support rod 8 is connected to the fixing tube 2, so that the fixing tube 2 is stably set on the fixing seat 10.

[0070] Furthermore, the polymer rib surface processing device provided in the present application also includes an extrusion die 1, which is arranged in a fixed cylinder 2. The extrusion die 1 has a cylindrical structure, and the outer wall surface of the cylindrical structure is formed with at least one limiting strip 101 extending along its length direction. The inner wall surface of the fixed cylinder 2 is formed with a limiting groove 202 adapted to the limiting strip 101. The limiting strip 101 is clamped in the limiting groove 202, so that the extrusion die 1 and the fixed cylinder 2 are relatively fixed to avoid relative rotation between the two. Preferably, the number of limiting strips 101 and limiting grooves 202 is the same, and both can be but are not limited to two, and each limiting strip 101 is correspondingly arranged in one of the limiting grooves 202.

[0071] The extrusion die 1 forms an extrusion channel 201 along the axis of the cylindrical structure. The two ends of the extrusion channel 201 are respectively a yarn inlet and a yarn extrusion port 102. The core rod 13 is essentially a fiber bundle. The fiber bundle impregnated with resin enters the extrusion die 1 through the yarn inlet and is released through the yarn extrusion port 102. During this process, the fiber bundle impregnated with resin is extruded and shaped to obtain the core rod 13.

[0072] Preferably, the polymer rib surface processing device provided in the present application also includes a first dipping tank, which is spaced apart from the fixing seat 10, and the yarn inlet of the extrusion mold 1 is located above the first dipping tank. More preferably, at least part of the yarn inlet is formed with a passivation slope, so that the inner diameter of the yarn inlet gradually increases along the depth direction of the extrusion channel 201, so that when the fiber bundle impregnated with resin passes through the extrusion channel 201, excess resin is retained at the yarn inlet, and under the guidance of the passivation slope, the resin can naturally flow back into the first dipping tank.

[0073] Furthermore, the first rotating component includes: a first rotating wheel 4, a first annular guide rail 7, and a first bearing 11, wherein the first rotating wheel 4 has an annular structure, the first bearing 11 is disposed in the inner ring of the annular structure of the first rotating wheel 4, and the first rotating wheel 4 is fixed to the first bearing 11, and the first bearing 11 is sleeved on the fixed cylinder 2 and rotatably connected to the fixed cylinder 2, thereby achieving a rotatable connection between the first rotating wheel 4 and the fixed cylinder 2, which not only enables the first rotating wheel 4 to rotate relative to the fixed cylinder 2 but also avoids direct friction between the first bearing 11 and the fixed cylinder 2. A plurality of yarn wheels 9 are arranged on the first rotating wheel 4 at equal intervals along the surface of the first rotating wheel 4, and the axis of each yarn wheel 9 is parallel to the axis of the first rotating wheel 4.

[0074] A plurality of first connecting rods are arranged at intervals on one side surface of the first rotating wheel 4 on which the yarn wheel 9 is provided, one end of each first connecting rod is fixed to the first rotating wheel 4, and the other end of each first connecting rod is connected to the first annular guide rail 7, thereby fixing the first annular guide rail 7 to the first rotating wheel 4.

[0075] The first annular guide rail 7 includes a first outer ring and a first inner ring with a diameter smaller than that of the first outer ring. The first inner ring is arranged inside the first outer ring, and preferably, the two are in the same plane. A plurality of first limit bars are arranged at equal intervals between the first inner ring and the first outer ring. The first inner ring and the first outer ring are connected by the plurality of first limit bars, and the plurality of first limit bars separate the first inner ring and the first outer ring into a plurality of first limit intervals. Preferably, the number of the first limit intervals is the same as the number of the yarn wheels 9 arranged on the first rotor 4. The fiber bundle released by each yarn wheel 9 passes through a corresponding first limit interval and is wound onto the core rod 13 to prevent multiple strands of wire from being entangled with each other.

[0076] Furthermore, the structure of the second rotating component is similar to that of the first rotating component. The second rotating component includes: a second runner 5, a second bearing 12 and a second annular guide rail 6. The second runner 5 also has an annular structure, and the diameter (outer diameter) of the second runner 5 is smaller than the diameter (outer diameter) of the first runner 4. The second bearing 12 is arranged in the inner ring of the annular structure of the second runner 5. Preferably, the inner ring of the second runner 5 is formed with a mounting groove 501, and the second bearing 12 is fixed in the mounting groove 501. At the same time, the second bearing 12 is sleeved on the fixed cylinder 2, so that the second runner 5 is rotatably connected to the fixed cylinder 2 through the second bearing 12.

[0077] A plurality of yarn wheels 9 are further provided on one side wall of the second rotor 5 . The plurality of yarn wheels 9 are arranged on the second rotor 5 at equal intervals, and the axis of each yarn wheel 9 is parallel to the axis of the second rotor 5 .

[0078] The wall surface of the second rotating wheel 5 on which the yarn wheel 9 is provided is further provided with a plurality of second connecting rods 601 at intervals. One end of each second connecting rod 601 is fixed to the second rotating wheel 5, and the other end of each second connecting rod 601 is connected to the second annular guide rail 6, thereby enabling the second annular guide rail 6 to be connected to and rotate synchronously with the second rotating wheel 5. Preferably, a plurality of mounting holes 502 for fixing the second connecting rods 601 are formed on the second rotating wheel 5, and one end of the second connecting rod 601 is inserted into the mounting hole 502.

[0079] Similarly, the second annular guide rail 6 includes a second outer ring 602 and a second inner ring 604, wherein the diameter of the second inner ring 604 is smaller than the diameter of the second outer ring 602, and the diameter of the second outer ring 602 is smaller than the diameter of the first inner ring. The second inner ring 604 is arranged inside the second outer ring 602, and a plurality of second limiting bars 603 are arranged at equal intervals between the second inner ring 604 and the second outer ring 602. The plurality of second limiting bars 603 separate the second inner ring 604 and the second outer ring 602 into a plurality of second limiting intervals. Preferably, the number of the second limiting intervals is the same as the number of the yarn wheels 9 arranged on the second rotor 5. The fiber bundles released by the plurality of yarn wheels 9 on the second rotor 5 pass through a corresponding second limiting interval one by one in sequence, and then are wound onto the core rod 13, thereby preventing the multiple strands of wire from being entangled with each other.

[0080] Furthermore, the polymer rib surface processing device provided in the present application also includes a driving member 3, which is disposed on the fixed cylinder 2 and is used to drive the first rotating wheel 4 and the second rotating wheel 5 to rotate. The driving member 3 can specifically be a motor having two output shafts, which are respectively connected to the first bearing 11 and the second bearing 12, thereby driving the first rotating wheel 4 and the second rotating wheel 5 to rotate. Alternatively, there are two driving members 3, which are respectively connected to the first bearing 11 and the second bearing 12, thereby respectively driving the first rotating wheel 4 and the second rotating wheel 5 to rotate.

[0081] Preferably, the driving member 3 is electrically or communicatively connected to the console described below, and the start and stop of the driving member 3 can be controlled by the console, and the rotation direction and speed of the first bearing 11 and the second bearing 12 driven by the driving member 3 can also be adjusted or set by the console.

[0082] Furthermore, the polymer tendon surface processing device provided in the present application also includes a traction device, which is spaced apart from the fixed component. The core rod 13 released through the yarn extrusion port 102 extends toward the direction of the first rotor 4 and the second rotor 5 and is connected to the traction device. The traction device can pull one end of the core rod 13, so that the impregnated fiber bundle can be pulled out from the extrusion channel 201 on the one hand, and on the other hand, while the yarn wheel 9 rotates with the first rotor 4 and the second rotor 5 to allow the fiber bundle to be wound around the core rod 13, the traction device continues to pull the core rod 13 so that the fiber bundle can be wound around the core rod 13 circle by circle, thereby avoiding excessive winding of the local fiber bundle on the core rod 13.

[0083] Preferably, the traction device is electrically connected or communicatively connected to the console, and the console controls the traction speed of the core rod 13 by the traction device.

[0084] It should be noted that the first rotating member and the second rotating member provided in the embodiment of the present application can be used alone or in combination.

[0085] When one of the first rotating member and the second rotating member is used, the fiber bundles released by each yarn wheel 9 on the first rotating wheel 4 or the second rotating wheel 5 are wound on the core rod 13 in the same direction, so that the fiber bundles released simultaneously by multiple yarn wheels 9 can form a braided layer on the surface of the core rod 13. Any two adjacent fiber bundles wound on the core rod 13 are parallel, and the sides of any two adjacent fiber bundles are close to each other, so that multiple fiber bundles together form a braided layer on the surface of the core rod 13, and the braided layer can cover the outer surface of the core rod 13.

[0086] Preferably, the first rotating member and the second rotating member operate simultaneously, rotate synchronously at the same angular velocity, and rotate in opposite directions. For ease of description, the fiber bundle released by the yarn wheel 9 on the first rotating wheel 4 is defined as the first fiber bundle, and the fiber bundle released by the yarn wheel 9 on the second rotating wheel 5 is defined as the second fiber bundle. It should be noted that both the first fiber bundle and the second fiber bundle have a relatively small width ribbon structure. Because the first rotating wheel 4 and the second rotating wheel 5 rotate in opposite directions, the first fiber bundle and the second fiber bundle can be cross-woven on the core rod 13.

[0087] It should be further explained that the materials of the fiber bundle used to make the core rod 13 and the first fiber bundle and the second fiber bundle used to be woven on the surface of the core rod 13 can be the same or different.

[0088] More preferably, the fiber bundles released by the multiple yarn wheels 9 on the first rotor 4 and the multiple yarn wheels 9 on the second rotor 5 are alternately wound onto the core rod 13. Specifically, before the polymer tendon surface processing device starts working, the fiber bundles on each yarn wheel 9 are fixed to the core rod 13 one by one in the order of first fiber bundle-second fiber bundle-first fiber bundle... When the first rotor 4 and the second rotor 5 rotate synchronously in opposite directions, the first fiber bundle and the second fiber bundle are cross-woven on the core rod 13, thereby forming an uneven woven layer on the surface of the core rod 13, thereby improving the strength, ductility and adhesion between the core rod 13 and the concrete.

[0089] Furthermore, the polymer tendon surface processing device provided in the present application also includes a second dipping tank 15. The traction device continuously pulls the core rod 13 at a uniform speed, so that the part with the braided layer is continuously pulled in the direction away from the fixed component. Resin is stored in the second dipping tank 15. The core rod 13 with a concave and convex surface formed after weaving enters the second dipping tank 15 for dipping, so that the braiding can be stably attached to the core rod 13 after curing, so that a workpiece with light weight, high strength, corrosion resistance, fatigue resistance and non-magnetic is obtained after the surface weaving is completed.

[0090] The second immersion tank 15 is provided with an inlet and an outlet, which are distributed along the axial direction of the core rod 13. The inlet and the outlet are both provided with a closed connector 16 to prevent the glue from leaking out when the core rod 13 is inserted into the inlet and the outlet. Preferably, a base 17 is provided at the bottom of the second immersion tank 15. More preferably, the base 17 has a lifting structure that can adjust the height of the second immersion tank 15 or the inlet and the outlet to keep the core rod 13 level.

[0091] In addition, the polymer reinforcement surface processing device provided in the embodiment of the present application also includes a high-temperature gel device and a high-temperature curing device. The core rod 13 with a braided layer is impregnated with resin through the second dipping tank 15 and then sequentially passed through the high-temperature gel device and the high-temperature curing device for high-temperature treatment. The ethylene resin undergoes sufficient polymerization reaction to form a high-density polymer. Finally, after cooling treatment by a cooling device and fixed-length cutting by a cutting device, an FRP reinforcement with a fabric surface in which the cross-sectional fiber distribution is distributed in a preset manner is realized.

[0092] The embodiments of the present application also provide a weaving method, including the processing method described in any of the above embodiments, and thus, has all the beneficial technical effects of the polymer rib surface processing device, which will not be repeated here.

[0093] This weaving method comprises the following steps:

[0094] First, the fiber bundles used to make the core rod 13 are regularly arranged according to a preset distribution pattern and impregnated with resin in a first dipping tank. Then, the fiber bundles impregnated with the resin are released through the yarn extrusion port 102 and cured to obtain the core rod 13.

[0095] Furthermore, the weaving parameters are determined. The first rotor 4 and the second rotor 5 rotate in opposite directions, one of which rotates clockwise and the other counterclockwise, and the angular velocity ω of the two is the same; the distance from the axis of the yarn wheel 9 to the center of the rotor is ; The widths of the first fiber bundle and the second fiber bundle are both The rib spacing of a single yarn wheel 9 is defined as the distance between any two adjacent ribs after each first fiber bundle (or each second fiber bundle) is wound several times on the surface of the core rod 13. The pulling speed of the traction device (not shown) on the core rod 13 is .

[0096] Furthermore, the knitting operation is performed according to the following formula:

[0097] (1) Wheel angular velocity: ;

[0098] (2) Weaving angle: , among which, Figure 11 As shown, the braiding angle is specifically the acute angle between the first fiber bundle or the second fiber bundle and the axis of the core rod 13;

[0099] (3) Rib spacing The number of inner fiber bands is: .

[0100] According to the above formula, the parameters of the weaving operation performed by the polymer tendon surface processing device are set, which can ensure that each first fiber bundle and each second fiber bundle can be covered with the surface of the core rod 13 in an overlapping manner when they are wound and woven on the core rod 13, ensuring the density of the braided layer so that the braided layer can cover the surface of the core rod 13.

[0101] According to the above formula, the traction speed of the traction device is input on the console. The fiber bundle impregnated with resin moves slowly under the action of the traction device and forms a core rod 13 after passing through the extrusion die 1.

[0102] Furthermore, the traction device continuously pulls the core rod 13 to bring the core rod 13 into the weaving link, and the angular velocity of the first wheel 4 and the second wheel 5 is input on the console. Under the driving action of the driving member 3, the first wheel 4 rotates clockwise, and the second wheel 5 rotates counterclockwise at the same angular velocity, so that multiple first fiber bundles and multiple second fiber bundles can form a weaving layer on the surface of the core rod 13 according to the arrangement order of the yarn wheel 9 to obtain a preformed rod 14.

[0103] Furthermore, after the braiding operation is completed, the traction device again pulls the core rod 13 with the braided layer into the second dipping tank 15 for resin impregnation, followed by high-temperature curing treatment, cooling treatment and other steps to obtain FRP reinforcement with a fabric surface.

[0104] In summary, the polymer reinforcement surface processing device provided in the present application can form a woven layer on the surface of the core rod so that the core rod has a concave and convex surface, thereby enhancing the adhesion with concrete and ensuring the density of the woven layer and the firmness between the woven layer and the core rod.
