Description

Technical Field

[0001] This application relates to the field of weaving device technology, and in particular to a multi-layer weaving system for molded fiberglass grating. Background Technology

[0002] Fiberglass grating, also known as fiberglass grating, is a plate-like material with many openings, made of fiberglass as reinforcement and unsaturated polyester resin as matrix, through a special processing and composite process. Fiberglass grating can be used as a structural material for floors, trench covers, platforms, ship decks, stairs, etc., in corrosive environments, and has advantages such as corrosion resistance, flame retardancy, non-magnetic properties, and electrical insulation.

[0003] Regarding the aforementioned technologies, in the production process of FRP grating, multiple layers of glass fiber need to be laid along the warp and weft directions inside the grating mold. In the existing technology, manual laying is generally used, which results in low overall laying efficiency of glass fiber and therefore needs to be improved. Summary of the Invention

[0004] To improve the low efficiency of manually laying fiberglass grating molds in both the warp and weft directions, this application provides a multi-layer weaving system for molded fiberglass gratings.

[0005] The technical solution provided in this application for a multi-layer woven glass fiber reinforced plastic (GFRP) grating system using warp and weft fibers is as follows:

[0007] By adopting the above technical solution, the drive structure drives the grid mold to move intermittently along the length of the frame. During the intervals of the grid mold movement, the weft yarn weaving component and the warp yarn weaving component weave the weft and warp yarns inside the grid mold, thereby achieving the purpose of multi-layer weaving in the warp and weft directions in the grid mold and improving the laying efficiency of glass fiber in the warp and weft directions of the grid mold.

[0008] Preferably, the weft yarn weaving assembly includes a weft yarn holder, a guide rod, a fabric yarn holder, a weft yarn tube, and a reciprocating component; the weft yarn holders are disposed opposite each other on both sides of the frame in the width direction, and the guide rod is disposed between the opposite weft yarn holders along the width direction of the frame; the fabric yarn holder is slidably sleeved on the guide rod, and the weft yarn tube is disposed at the end of the fabric yarn holder facing the grid mold for the weft yarn to pass through; the reciprocating component is disposed on the frame to drive the fabric yarn holder to reciprocate along the length direction of the guide rod.

[0009] By adopting the above technical solution, the reciprocating component drives the yarn holder to move the weft tube back and forth along the length of the guide rod, so as to weave the weft yarn into the grid mold through the weft tube. In conjunction with the drive structure to drive the grid mold to move, the automated weft yarn weaving is realized.

[0010] Preferably, the warp weaving assembly includes fixing rods, mounting frames, and warp tubes; the fixing rods are arranged opposite each other on both sides of the frame in the width direction, the mounting frames are sleeved on the two sets of fixing rods, and the length direction of the mounting frames is parallel to the width direction of the frame; the warp tubes are spaced apart on the mounting frames along the length direction of the mounting frames to allow radial yarns to pass through, and the end of each warp tube facing the frame is bent along the conveying direction of the grid mold.

[0011] By adopting the above technical solution, the warp yarns pass through the curved warp tube to be arranged inside the grid mold, and in conjunction with the movement of the grid mold, the automated weaving of the warp yarns is realized. In addition, the curved warp tube reduces the phenomenon of breakage and damage caused by wear between the warp yarns and the inner wall of the warp tube when the warp yarns pass through the warp tube, thus improving the quality of the fabric.

[0012] Preferably, the weft tube is rotatably connected to the yarn support, and the yarn support is provided with a rotating component to drive the weft tube to rotate following the weft yarn; the frame is provided with a return component to drive the weft tube to return to its original position.

[0013] By adopting the above technical solution, the rotating component makes the weft tube rotate automatically following the weft yarn, reducing the phenomenon of breakage and damage caused by wear between the weft yarn and the inner wall of the weft tube when the weft yarn passes through the weft tube, thus improving the quality of the fabric. In addition, the straightening component drives the weft tube located on the side of the grid mold to straighten, so that the weft tube can cooperate with the intermittent movement of the grid mold to arrange and weave the weft yarn in the remaining grooves of the grid mold, and reduce the interference caused to the movement of the grid mold.

[0014] Preferably, the rotating assembly includes a yarn block, a rotating shaft, an extension rod, and a limiting frame; the yarn block is rotatably mounted on the yarn seat, and the weft tube passes through the yarn block; the rotating shaft is rotatably mounted at the end of the yarn seat facing the frame, and the yarn block is located on the rotating shaft; the extension rod is located at the top of the yarn block, and the limiting frame is located on the side wall of the yarn seat facing the extension rod, with the extension rod located between the limiting frames to limit the rotation angle of the extension rod; the return assembly includes a positioning frame and a return member; the positioning frames are arranged opposite each other on both sides of the frame in the width direction, and the return member is arranged on the side walls of the two sets of positioning frames facing each other to push the extension rod back to a vertical state.

[0015] By adopting the above technical solution, the rotating shaft enables the yarn block and weft tube to rotate automatically following the weft yarn arrangement direction, reducing the wear and tear on the inner wall of the weft tube when the weft yarn passes through it, thus improving the yarn quality. The extension rod limits the rotation angle inside the limiting frame, reducing the risk of excessive rotation of the yarn block and weft tube, which could lead to weft yarn breakage. The reciprocating component drives the yarn seat to move the yarn block to the side of the grid mold, and the output end of the return component pushes the extension rod so that the extension rod drives the yarn block and weft tube back to the vertical state.

[0017] By adopting the above technical solution, during the process of the reciprocating component driving the yarn holder to move the yarn block, the bottom of the drive cam abuts against the drive plate to drive the extension shaft to rotate, and the rotating shaft, yarn block and weft tube automatically rotate and tilt, reducing the need for the weft tube to be pulled to drive the weft tube to rotate and tilt, further reducing the wear between the weft yarn and the weft tube and the breakage of the weft yarn, and further improving the quality of the yarn; when the yarn holder drives the yarn block to move to the side of the grid mold, that is, the drive cam moves into the return space, the drive cam releases the contact with the drive plate, and with the help of the gravity ball, the extension shaft, rotating shaft, yarn block and weft tube quickly and automatically return to the vertical state.

[0018] Preferably, the frame is provided with several sets of pressing components at intervals along the length of the frame to assist in pressing and fixing the weft yarn and the radial yarn; the frame is also provided with several sets of auxiliary pressing components at intervals along the length of the frame to assist in pressing the yarn on both sides of the grid mold.

[0019] By adopting the above technical solution, the pressing component compacts the weft and radial yarns inside the grid mold, and the auxiliary pressing component compacts the yarns on both sides of the grid mold, reducing the phenomenon of yarn floating inside the grid mold and ensuring the weaving quality of the warp and weft yarns inside the grid mold.

[0022] Preferably, the auxiliary pressing assembly includes an auxiliary pressing frame, an auxiliary pressing plate, an adjusting screw, and a locking nut; the auxiliary pressing frames are arranged opposite each other on both sides of the machine frame in the width direction, the auxiliary pressing plate is arranged on the side of each set of auxiliary pressing frames facing the machine frame, and the side wall of the auxiliary pressing plate facing the grid mold has a guide surface for pressing the yarn; the adjusting screw passes through the auxiliary pressing frame and is connected to the auxiliary pressing plate; the locking nut is threaded onto the adjusting screw and abuts against the auxiliary pressing frame to limit the position of the adjusting screw.

[0023] By adopting the above technical solution, the locking nut and the adjusting screw cooperate to adjust the height of the auxiliary pressure plate, and together with the drive structure, drive the grid mold to move, so that the guide surface at the bottom of the auxiliary pressure plate compacts and fixes the yarn on both sides inside the grid mold during the movement.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] By setting a driving structure to drive the grid mold to move intermittently along the length of the frame, during the intervals of the grid mold movement, the weft yarn weaving component and the warp yarn weaving component weave the weft and warp yarns inside the grid mold, thereby achieving the purpose of multi-layer weaving in the warp and weft directions in the grid mold and improving the laying efficiency of glass fiber in the warp and weft directions of the grid mold.

[0026] By setting a rotating component, the weft tube automatically rotates with the weft yarn, reducing the wear and breakage caused by the weft yarn passing through the inner wall of the weft tube when it exits, thus improving the quality of the fabric. In addition, the return component drives the weft tube located on the side of the grid mold to return to the correct position, so that the weft tube can cooperate with the intermittent movement of the grid mold to arrange and weave the weft yarn in the remaining grooves of the grid mold, and reduce the interference caused to the movement of the grid mold.

The yarns are arranged neatly and aesthetically pleasingly, with a large amount of warp and weft yarns that remain orderly, greatly improving yarn production efficiency and quality.
