Description

Technical Field

[0001] This invention belongs to the field of construction, specifically, it relates to a fiber mesh for concrete, as well as processing equipment and processing method. Background Technology

[0002] Fiberglass reinforced concrete (FRP) is made of glass fiber, basalt fiber, or other fibers, either alone or in combination with resin and cured. It possesses high strength and strong corrosion resistance, making it a common replacement for steel mesh in concrete pouring. In existing technologies, FRP mesh is typically formed by intersecting warp and weft fibers. The intersections are often secured using wire binding or manual twisting and weaving. However, the binding wires are susceptible to corrosion, which can lead to loosening and instability of the mesh structure, reducing its structural strength and consequently affecting the overall structural strength of the concrete. Manual twisting and weaving, on the other hand, is inefficient and labor-intensive. Summary of the Invention

[0003] This invention provides a fiber reinforced mesh for concrete, which is used in the processing of fiber reinforced mesh to firmly connect the warp and weft bars of the fiber reinforced mesh together in a special connection method. This solves the problems of the risk of structural loosening and instability caused by the use of metal wire to tie the intersection of the warp and weft fibers in the existing technology, which affects the overall structural strength of the concrete, as well as the high labor intensity and low work efficiency of manual twisting and weaving.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A concrete fiber reinforcement mesh processing equipment includes a frame, on which a rotating mechanism for weaving fiber reinforcement mesh is provided. A traction mechanism is provided in front of the rotating mechanism, a warp fiber bundle supply device is provided behind it, and a weft fiber reinforcement supply device is provided on the side. Under the pulling force of the traction mechanism, the warp fiber bundle and the weft fiber reinforcement are woven into a mesh-like fiber reinforcement mesh by the rotating mechanism, and then cured in a heating tunnel kiln between the rotating mechanism and the traction mechanism.

[0006] The processed fiber mesh includes weft fiber ribs and warp fiber ribs that are fixedly connected in a grid-like structure. The weft fiber ribs pass through the middle of the warp fiber ribs and are fixed by resin gelation.

[0007] Furthermore, the rotating mechanism includes a power unit and several rotating units. The several rotating units are rotatably mounted on the frame via a back plate. The power unit is mounted on the back plate and drives the several rotating units to perform twisting and weaving actions on the warp fiber bundles and weft fiber ribs.

[0008] Furthermore, the rotating unit includes a disc, a hollow gear, and a bearing. The back plate has mounting holes that fit the outer ring of the bearing. One end of the hollow gear is rotatably mounted on the back plate through the bearing, and the disc is fixedly mounted on the other end of the hollow gear. The hollow gears of several rotating mechanisms mesh with each other.

[0009] Furthermore, the hollow gear includes a gear body and a bushing arranged coaxially. The gear body is located outside the bushing, and the bushing has a wire passage in the middle for the passage of the radial fiber bundle. The two ends of the bushing extend out of the gear body for the installation of bearings and discs. The bushing and the gear body are integrally formed or assembled separately.

[0010] Furthermore, the disc has two thread-passing holes that divide a warp fiber bundle into two warp fiber bundles. The two thread-passing holes are symmetrically distributed on both sides of the disc axis. The weft fiber tendons pass through the two warp fiber bundles through the two thread-passing holes and are twisted and woven by the power unit.

[0011] Furthermore, the power unit includes a power motor and a reducer. The reducer is fixed on the back plate, and the power motor drives several hollow gears to mesh and rotate through the reducer and the drive gear.

[0012] Furthermore, the disk is also provided with a groove for guiding the weft fiber reinforcement. The groove passes through the center of the front end face of the disk and is perpendicular to the axis. Two wire holes are symmetrically distributed on both sides of the groove.

[0013] Furthermore, the rotating mechanism also includes a wire-pulling unit for pulling the weft fiber from the groove and a cutting unit for cutting the weft fiber. The wire-pulling unit is mounted on the frame, and the cutting unit is mounted on the frame and located on the side where the weft fiber enters.

[0014] Furthermore, the disc has a groove for guiding the weft fiber reinforcement. The groove passes through the center of the front end face of the disc and is perpendicular to the axis. Two wire holes are symmetrically distributed on both sides of the groove.

[0015] Furthermore, the warp fiber bundle supply device includes a warp fiber bundle feeding frame, an impregnation tank, and a fiber bundle forming mold arranged in sequence. The warp fiber bundle feeding frame is located behind the impregnation tank, and several warp fiber bundle feeding wheels are rotatably mounted on the warp fiber bundle feeding frame. The fiber bundle forming mold is located in front of the impregnation tank, and a rotating mechanism is located in front of the fiber bundle forming mold. A pressing mechanism is provided on the impregnation tank, and wire rollers are provided on both sides of the impregnation tank.

[0016] This invention also discloses a method for processing fiber reinforced mesh for concrete, comprising the following steps:

[0017] Step 1: Preparation and equipment adjustment. Adjust the warp fiber bundle supply device, weft fiber rib supply device, and rotating mechanism to their initial state. Stretch the warp fiber bundle and weft fiber rib to the starting position before weaving to prepare for the weaving work.

[0018] Step 2: Laying out and impregnating the warp fiber bundle. Under the pulling force of the traction mechanism, the warp fiber bundle is laid out and impregnated with adhesive through the warp fiber bundle supply device.

[0019] Step 3: De-adhesive molding. Excess resin is squeezed out from the impregnated warp fiber bundles, and the warp fiber bundles are shaped.

[0020] Step 4: Warp and weft interlacing. The weft fiber tendon is passed through multiple warp fiber bundles of all the warp fiber tendons in sequence. The position where it passes through is located in the middle position perpendicular to the length direction of the warp fiber bundle, that is, to ensure that the warp fiber tendon and the weft fiber tendon remain perpendicular.

[0021] Step 5: Twisting and weaving. The warp fiber bundles are twisted into ribs by a rotating mechanism, while the weft fiber ribs are twisted and limited, to process an uncured weft and warp fiber ribs into a grid-like structure.

[0022] Step 6: Curing and molding. Under the pulling force of the traction mechanism, the uncured fiber mesh is sent to the heated tunnel kiln to cure and mold the fiber mesh.

[0023] Step 7: Mesh Storage. After the fiber reinforced mesh has cured in the tunnel kiln, pull it out and cut it into pieces or roll it up for storage.

[0024] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned structure, are as follows:

[0025] This invention creatively inserts weft bars into the middle of the warp bars while producing the warp bars, and achieves a stable connection at the intersection of the two bars through resin curing. Simultaneously with the production of the warp bars, the intersecting mesh is also fabricated, solving the connection strength problem between the warp and weft bars. It also eliminates the need for wire binding, avoiding instability in the mesh structure caused by corrosion or loosening of the wires later on. This improves production efficiency, reduces processing costs, and enhances the overall structural strength and stability of concrete, making it suitable for the field of building technology.

Detailed Implementation

[0039] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0040] This invention discloses a processing equipment for fiber reinforced mesh in concrete, such as... Figure 1 As shown, the machine includes a frame 04, on which a rotating mechanism 07 for weaving fiber reinforcement mesh is provided. A traction mechanism 03 is provided in front of the rotating mechanism 07, a warp fiber bundle supply device is provided behind it, and a weft fiber reinforcement 01 supply device is provided on the side. Under the pulling force of the traction mechanism 03, the warp fiber bundle 2 and the weft fiber reinforcement 01 are woven into a mesh-like fiber reinforcement mesh by the rotating mechanism 07, and then cured in a heating tunnel kiln 41 between the rotating mechanism 07 and the traction mechanism 03.

[0041] As a specific embodiment of the present invention, such as Figure 1 As shown, the rotating mechanism 07 includes a power unit and several rotating units. The rotating units are rotatably mounted on the frame 04 via a back plate 06. The power unit is mounted on the back plate 06 and drives the rotating units to perform a twisting and weaving action on the warp fiber bundles 2 and the weft fiber ribs 01. Figures 3-4As shown, the rotating unit includes a disk 713, a hollow gear 71, and a bearing 712. A mounting hole adapted to the outer ring of the bearing 712 is provided on the back plate 06. One end of the hollow gear 71 is rotatably mounted on the back plate 06 via the bearing 712, and the disk 713 is fixedly mounted on the other end of the hollow gear 71. The hollow gears 71 of several rotating mechanisms 07 mesh with each other. The hollow gear 71 includes a gear body 711 and a bushing 7111 coaxially arranged. The gear body 711 is located outside the bushing 7111. A wire passage 7110 for the passage of the radial fiber bundle 2 is provided in the middle of the bushing 7111. Both ends of the bushing 7111 extend beyond the gear body 711 for the installation of the bearing 712 and the disk 713. The bushing 7111 and the gear body 711 are integrally formed or assembled separately. The disc 713 has two thread-passing holes 7132 that divide a warp fiber bundle 2 into two warp fiber bundles 2. The two thread-passing holes 7132 are symmetrically distributed on both sides of the axis of the disc 713. The weft fiber rib 01 passes through the two warp fiber bundles 2 through the two thread-passing holes 7132 and twists and weaves the two warp fiber bundles under the action of the power unit. Figure 2 As shown, the power unit includes a power motor and a reducer 72. The reducer 72 is fixed on the back plate 06. The power motor drives several hollow gears 71 to mesh and rotate through the reducer 72 and the drive gear 74.

[0042] Before the rotating mechanism 07 twists the multiple warp fiber bundles 2, the weft fiber ribs 01 are sequentially passed through the multiple warp fiber bundles 2 of all the warp fiber ribs 02. The position where they pass through is located at the middle position perpendicular to the length direction of the warp fiber bundles 2, that is, to ensure that the warp fiber ribs 02 and the weft fiber ribs 01 remain perpendicular. Then, the rotating mechanism 07 starts to rotate, twisting the multiple warp fiber bundles 2 into a strand, and at the same time, the weft fiber ribs 01 inserted into them are also limited by the above twisting.

[0043] To ensure that the weft rib passes through the middle of the multiple warp fiber bundles 2, each warp fiber bundle 2 is divided into two, namely, a first warp fiber bundle 21 and a second warp fiber bundle 22, which pass through the two thread-passing holes 7132 on the disc 713, so that the weft rib 01 passes through the middle of the two warp fiber bundles. The warp fiber bundles coming out of the forming mold pass through the back plate 06, the inner ring of the bearing 712, and the hollow gear 71, that is, through the thread-passing channel 7110 of the bushing 7111, and then pass through the two round holes on the disc 713, and then reassembled. They are then connected to the traction mechanism 03 through the heated tunnel kiln, and the weft rib 01 passes through the groove 7131 on each disc 713.

[0044] As a specific embodiment of the present invention, such as Figure 1 , Figure 6As shown, the disc 713 also has a groove 7131 for guiding the weft fiber 01. The groove 7131 passes through the center of the front end face of the disc 713 and is perpendicular to the axis. Two wire holes 7132 are symmetrically distributed on both sides of the groove 7131. The rotating mechanism 07 also includes a wire pulling unit 60 for pulling the weft fiber 01 out of the groove 7131 and a cutting unit 05 for cutting the weft fiber 01. The wire pulling unit 60 is mounted on the frame 04, and the cutting unit 05 is mounted on the frame 04 and located on the side where the weft fiber 01 enters.

[0045] like Figure 4 As shown, disk 713 is connected to hollow gear 71, hollow gear 71 is connected to the inner ring of bearing 712, and the outer ring of bearing 712 is connected to back plate 06. The distance between the two wire holes 7132 on disk 713 is less than the diameter of the inner ring of bearing 712, but greater than the width of the groove 7131 on disk 713. The width and depth of groove 7131 are adapted to the diameter of weft fiber rib 01, such as... Figure 5 As shown, the disk 713 has an installation step hole 7133 that is adapted to the bushing 7111 on the side near the hollow gear 71.

[0046] like Figure 6 , Figure 7 As shown, the cutting unit 05 includes a cutting cylinder 56, a cutting blade 55, a mounting plate 51, and a blade holder 54. The bottom end of the blade holder 54 is fixedly connected to the side of the frame 04. The fixed end of the cutting cylinder 56 is fixedly connected to the blade holder 54, and the movable end is equipped with the cutting blade 55. A square hole 540 is provided on the blade holder 54 for the weft fiber 01 to pass through. A pair of wire feeding rollers 52 are provided outside the square hole 540. A wire feeding motor 53 is provided on the blade holder 54 for driving the wire feeding rollers 52 to rotate and feed the wire. Figure 7 As shown, a cutting blade 55 is provided at the lower inner side of the square hole 540. The cutting blade 55 is connected to the movable end of the cutting cylinder 56, and the fixed end of the cutting cylinder 56 is fixed on the fork 54.

[0047] Under the action of the feeding roller 52, the weft fiber rib 01 is fed into the groove 7131. When the required feeding length for the braiding width is reached, the cutting cylinder 56 is activated, pushing the cutting blade 55 to cut the weft fiber rib 01 and then reset, thus realizing the supply of the weft fiber rib 01. The feeding motor 53 is a stepper motor, and the number of rotations of the feeding roller 52 is controlled by an encoder to control the feeding length of the weft fiber rib 01. The feeding motor 53 and the cutting cylinder 56 are controlled by a control system.

[0048] like Figure 9As shown, the wire-picking unit 60 includes a movable wire-picking assembly 61 and a fixed wire-picking assembly 62. The fixed wire-picking assembly 62 is fixedly disposed inside the cutting unit 05. The movable wire-picking assembly 61 is movably installed in front of the rotating unit through a translation mechanism. The movable wire-picking assembly 61 includes a wire-picking cylinder 612, a fork 614, and a slide 615. The bottom end of the fork 614 is hinged to the slide 615, and the top end is provided with a U-shaped wire-picking groove 613 adapted to the weft fiber rib 01. The opening direction of the wire-picking groove 613 is consistent with the traveling direction of the warp fiber bundle 2. The two ends of the wire-picking cylinder 612 are respectively hinged to the slide 615 and the fork 614. The translation mechanism includes a translation motor 611 and a lead screw 616. One end of the lead screw 616 is rotatably connected to the frame 04, and the other end is connected to the translation motor 611 and threadedly connected to the slide 615. The translation motor 611 is fixed on one side of the frame 04. The frame 04 has a slide groove that matches the slide 615. The translation motor 611 drives the slide 616 to move laterally along the frame 04 through the lead screw 616. The shift fork 614 can move laterally on the frame 04 along with the slide 615.

[0049] For fiber mesh with different spans, the number of grooves 7131 on the hollow gear 71 through which the weft fiber 01 passes is different. If the distance between the two forks 614 is too large or too small, the cut weft fiber 01 cannot be pulled out in time, resulting in one end of the weft fiber 01 being pulled out while the other end remains in the groove 7131. This affects the mesh weaving quality and delays production. Therefore, it is necessary to adjust the distance between the two forks 614 according to the weaving width of the fiber mesh to ensure that the weft fiber 01 can be pulled out from the groove 7131 in time, preparing for the next step of twisting and weaving. The fixed wire-pulling assembly 62 is located on one side of the frame 04, and the movable wire-pulling assembly 61 is movably installed on the frame 04 through a translation mechanism. The translation motor 611 drives the lead screw 616 to rotate, which in turn drives the slide 615 and the shift fork 614 to move. The distance between the two shift forks 614 can be adjusted according to the weaving width of the fiber reinforcement mesh to ensure that the weft fiber reinforcement 01 can be smoothly pulled out from the groove 7131, thus ensuring the weaving quality of the fiber reinforcement mesh and the smooth progress of production. It is suitable for weaving fiber reinforcement mesh of different widths.

[0050] As a specific embodiment of the present invention, such as Figure 1As shown, the warp fiber bundle supply device includes a warp fiber bundle feeding frame 20, an impregnation tank 10, and a fiber bundle forming mold 23 arranged sequentially. The warp fiber bundle feeding frame 20 is located behind the impregnation tank 10, and several warp fiber bundle 2 feeding wheels are rotatably mounted on the warp fiber bundle feeding frame 20. The fiber bundle forming mold 23 is located in front of the impregnation tank 10, and a rotating mechanism 07 is located in front of the fiber bundle forming mold 23. A pressing mechanism 09 is provided on the impregnation tank 10, and guide rollers 08 are provided on both sides of the impregnation tank 10. A guide plate 42 for guiding the warp fiber bundle 2 is provided behind the frame 04. The warp fiber bundle 2 coming out of the warp fiber bundle feeding frame 20 passes through the guide holes on the guide plate 42 and enters the impregnation tank 10 through the guide rollers 08. The weft fiber reinforcement supply device includes a weft fiber reinforcement feeding frame 101 and a weft fiber reinforcement feeding wheel 102. The weft fiber reinforcement feeding wheel 102 is rotatably mounted on the weft fiber reinforcement feeding frame 101, and the weft fiber frame is provided with a weft fiber reinforcement feeding mechanism.

[0051] The warp fiber bundles 2 required for the production of warp fiber ribs 02 are impregnated with resin in the impregnation tank 10. The warp fiber bundles 2 are then shaped by the molding mold, while excess resin in the warp fiber bundles 2 is squeezed out. After impregnation, the warp fiber bundles 2 are twisted together by the clockwise and counterclockwise twisting mechanism 07 to form the warp fiber ribs 02.

[0052] The fiber bundle forming mold 23 is a cylindrical structure. Multiple fiber bundle forming molds 23 are arranged sequentially according to the number of warp fiber bundles 2 and fixedly installed on the frame 04 by a vertical plate. The center of the mold is provided with a forming channel for extruding and forming the warp fiber bundle 2. The forming channel is a conical structure with a large inlet and a small outlet. After being impregnated with resin, the warp fiber bundle 2 can pass through the forming mold and gradually extrude excess resin and be shaped as it changes shape in the gradually narrowing forming channel.

[0053] like Figure 8As shown, the pressing mechanism 09 includes a pressing roller 90. The two ends of the pressing roller 90 are elastically connected to the two ends of the impregnation tank 10 through a tensioning unit. The tensioning unit includes a U-shaped frame 91 and a pressing cylinder 97. The fixed end of the pressing cylinder 97 is fixedly connected to the end face of the impregnation tank 10. One side of the U-shaped frame 91 is rotatably connected to the pressing roller 90. The U-shaped frame 91 is provided with a U-shaped groove 910 that is adapted to the side wall of the impregnation tank 10, which can ensure that the U-shaped frame 91 can move up and down across its side wall. The other side is movably connected to the movable end of the pressing cylinder 97 through the tensioning unit. The tensioning unit includes a slide block 96 and a spring 93. A slider 95 is provided on the outer side of the U-shaped frame 91. The bottom end of the slide block 96 is fixedly connected to the movable end of the pressing cylinder 97. A groove adapted to the slider 95 is provided on the slide block 96. The slider 95 is slidably installed in the groove and is limited by the positioning block 94 and the positioning bolt to prevent the slider 95 from coming out of the groove. The top of the slider 95 is movably connected to the top of the groove by the spring 93. The top of the slide block 96 is provided with an adjusting screw 92 for adjusting the stroke of the slider 95 and the extension of the spring 93.

[0054] The working principle of this tensioning unit is as follows: Under normal tension, the pressure roller 90 rotates smoothly to press the fiber bundle into the resin in the impregnation tank 10. When the fiber bundle experiences a sudden increase in tension due to a failure in the unwinding process or excessive twisting of the weaving equipment, the multiple fiber bundles will tighten instantly. The pressure roller 90 will be lifted upwards by an upward force, causing it to rise to a certain height. This upward force will compress the springs 93 in the grooves at both ends of the impregnation tank 10, which will counteract the elastic resistance of the springs 93, thus providing a certain buffering effect and preventing the fiber bundle from breaking due to a sudden increase in tension. By rotating the adjusting screw 92, the compression stroke of the spring 93 can be changed, thereby changing the rising height of the pressure roller 90, which in turn changes the tension and adapts to the requirements of the weaving equipment for the number of twisting turns of the fiber bundle. If the number of twisting turns is too large, the tension will change significantly, so the stroke of the spring 93 will be adjusted to be larger, resulting in a higher tension; conversely, if the number of twisting turns is too small, the stroke of the spring 93 will be adjusted to be smaller.

[0055] The function of the pressing mechanism 09 is as follows: Firstly, the extension and retraction of the pressing cylinder 97 facilitates the installation of the warp fiber bundle 2. Before impregnation, the pressing roller 90 can be raised to allow the warp fiber bundle 2 to pass through from below. During impregnation, the pressing roller 90 can press the warp fiber bundle 2 below the liquid surface of the impregnation tank 10. The pressing height can be adjusted according to the change in liquid level during impregnation to prevent impregnation failure due to changes in liquid level, ensuring that the warp fiber bundle 2 is always below the liquid surface and guaranteeing the impregnation effect. Secondly, when the rotating mechanism 07 twists the warp fiber bundle into ribs, it pulls the warp fiber bundle. If the warp fiber bundle is too loose, it will affect the twisting tightness and the forming effect. The effect varies depending on the number of twists. If it is too tight, the warp fiber bundle will be broken. The tensioning unit can ensure the tightness of the warp fiber bundle 2, preventing it from being too loose or too tight, which would affect the quality of the web or cause breakage and delay production.

[0056] Each rotating unit is connected to its adjacent rotating unit by meshing with a hollow gear 71, and is ultimately connected to the drive motor 73. The drive motor 73 is a servo motor, which provides power and controls the number of rotations each time. During installation and debugging, ensure that the grooves 7131 on each disc 713 are on the same straight line, parallel to the ground, and perpendicular to the direction of the warp fiber ribs 02. The length of the warp fiber ribs 02 in each grid of the fiber rib mesh is defined as the length, and the length of the weft fiber ribs 01 is defined as the width.

[0057] During operation, the traction mechanism 03 pulls the warp fiber bundle 2 or the fiber mesh forward, while the fork pulls the cut weft fiber rib 01 out of the groove 7131. The rotating unit begins to rotate clockwise or counterclockwise. When the traction mechanism 03 pulls the warp fiber bundle 02 forward to a certain length, it stops moving forward. The rotating unit completes the required number of rotations and stops rotating. Then, the weft fiber rib 01 continues to be laid out, and a new weft fiber rib 01 is inserted into the groove. After reaching the specified length, it is cut by the cutting blade 55 to form a second weft fiber rib 01, which is then pulled out by the fork. The traction mechanism 03 continues to pull forward to the next length, while the rotating unit begins to rotate the same number of times, but in the opposite direction to the previous rotation, i.e., counterclockwise or clockwise. This process is repeated until the entire mesh is produced.

[0058] It should be noted that adjacent rotating units interlock with each other, and during rotation, the rotation directions of adjacent rotating units are opposite. This can effectively prevent the inserted latitudinal fiber rib 01 from rotating clockwise or counterclockwise after completing one rotation, and ultimately the latitudinal rib is flat and the ends do not curl up.

[0059] like Figure 10As shown, the woven concrete fiber mesh includes weft fiber ribs 01 and warp fiber ribs 02 connected in a crisscrossing grid structure. The weft fiber ribs 01 pass through the middle of the warp fiber ribs 02 and are fixed by resin curing. The weft fiber ribs 01 pass through the middle of the warp fiber ribs 02 and are fixed by resin curing. The weft fiber ribs 01 and warp fiber ribs 02 do not need to be tied with metal wire. This method of fixing the warp ribs and their intersections using a combination of interlocking, twisting, and resin curing prevents loosening and ensures the overall structural stability of the mesh while also providing corrosion resistance.

[0060] In one specific embodiment of the present invention, the weft fiber rib 01 includes a weft fiber bundle 11 and a rope 12. The rope 12 is spirally wound around the weft fiber bundle 11, and both are glued and fixed with resin to form a rod-like structure. The warp fiber rib 02 with the rod-like structure is pre-processed and stored in a coil shape on a roller for later use. When needed, it is unloaded from the roller and passed through the ribs of the glue-impregnated warp fiber rib 02 to form a fiber rib mesh with a grid structure. Then, it is placed in a heated tunnel kiln for curing and molding to form a structurally stable fiber rib mesh.

[0061] In one specific embodiment of the present invention, the warp fiber rib 02 comprises several warp fiber bundles 2, and the weft fiber rib 01 passes through the middle of the several warp fiber bundles 2. The several warp fiber bundles 2 are twisted and then fixed by resin gelation. The twisting directions of the two warp fiber bundles 2 are forward and reverse twisting, and the two warp fiber bundles 2 on both sides of the intersection of each weft fiber rib 01 and warp fiber rib 02 are twisted in opposite directions.

[0062] The weft fiber rib 01 passes through the middle of several warp fiber bundles 2, thus forming an intersection point between the weft fiber rib 01 and the warp fiber rib 02. The warp fiber rib 02 is positioned by a twisting and gluing method to fix the intersection point and achieve a fixed connection. Each time the weft fiber rib 01 passes through the rib of the warp fiber rib 02, the twisting direction is changed, so that the warp fiber bundle 2 to be processed will not become disordered and unable to be separated under the twisting action in one direction.

[0063] In one specific embodiment of the present invention, the number of warp fiber bundles 2 is two, namely a first warp fiber bundle 21 and a second warp fiber bundle 22. The weft fiber reinforcement 01 passes through the middle of the two warp fiber bundles 2, and the two warp fiber bundles 2 are twisted and fixed by resin gelation. In the present invention, the number of warp fiber bundles 2 is two. Of course, the number of warp fiber bundles 2 can be changed according to actual needs to meet the overall structural strength of the concrete.

[0064] The woven fiber mesh is pulled into the heating tunnel kiln by the traction mechanism 03. The resin on the warp fiber bundle is heated and cured in the tunnel kiln. At the same time, it is also bonded and cured together with the weft fiber ribs 01. After the fiber mesh is cured in the tunnel kiln, it is pulled out, cut into pieces or rolled up and stored.

[0065] This invention also discloses a method for processing fiber reinforced mesh for concrete, comprising the following steps:

[0066] Step 1: Preparation and equipment adjustment. Adjust the warp fiber bundle supply device, the weft fiber rib 01 supply device, and the rotating mechanism 07 to their initial state. Stretch the warp fiber bundle 2 and the weft fiber rib 01 to the starting position before weaving to prepare for the weaving work.

[0067] Step 2: Laying out and impregnating the warp fiber bundle. Under the pulling force of the traction mechanism 03, the warp fiber bundle is laid out and impregnated with adhesive through the warp fiber bundle supply device.

[0068] Step 3: De-adhesive molding. Excess resin is squeezed out from the impregnated warp fiber bundles, and the warp fiber bundles are shaped.

[0069] Step 4: Weft and lattice interlacing. The lattice fiber 01 is passed through the multiple warp fiber bundles 2 of all the warp fiber 02 in sequence. The position where it passes through is located in the middle position perpendicular to the length direction of the warp fiber bundle 2, that is, to ensure that the warp fiber 02 and the lattice fiber 01 remain perpendicular.

[0070] Step 5: Twisting and weaving. The warp fiber bundles are twisted into ribs by the rotating mechanism 07, while the weft fiber ribs 01 are twisted and limited, and processed into an uncured weft fiber rib 01 and warp fiber rib 02 interwoven in a grid-like structure.

[0071] Step 6: Curing and molding. Under the pulling force of the traction mechanism 03, the uncured fiber mesh is sent to the heating tunnel kiln to cure and mold the fiber mesh.

[0072] Step 7: Mesh Storage. After the fiber reinforced mesh has cured in the tunnel kiln, pull it out and cut it into pieces or roll it up for storage.

[0073] In summary, this invention uses a rotating mechanism 07 to twist and weave the warp fiber bundle 2 and weft fiber rib 01, followed by resin curing to form a stable connection. This eliminates the need for metal wires to bind the warp and weft ribs, while ensuring the stability of the connection between the warp and weft ribs in the fiber mesh. This achieves automated production, reduces the labor intensity of workers, improves production efficiency, and is applicable to the field of building material processing equipment technology.
