Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of metal mesh weaving machines, and in particular, to a metal mesh weaving machine and a weaving process. Background Art

[0002] The weaving of metal mesh includes five major processes: warp let-off, shedding, weft insertion, weft beating-up and take-up. These processes are continuously circulated on the weaving machine, interweaving the metal wires into a metal mesh with a certain structure.

[0003] Letting off: Similar to unwinding, the warp beam is fixed and the warp is unwound, and the warp is evenly sent out on the let-off beam; Shedding: Each warp thread passes through the eyelet in a certain order. When the two heald frames move up and down alternately, the warp threads passing through the eyelet rise and fall with the heald frames and separate into two pieces, forming a shedding. Weft guiding: The weft guiding mechanism shuttles horizontally at the twist mouth, guides the weft into the twist mouth, maintains the tension of the weft and cuts the weft; Beating-up: The beating-up mechanism swings back and forth to push the introduced weft yarn forward smoothly to the cloth fell; Winding: Similar to reeling, the woven wire mesh is rolled onto a winding roller for collection.

[0004] The braiding machine in the prior art usually only has one winding roller when collecting the metal mesh at the end. The machine needs to be stopped to replace the winding roller every time the collection is completed, which affects the production efficiency. Therefore, it is necessary to improve the winding part of the existing braiding machine to achieve non-stop roller replacement and improve production efficiency. Summary of the Invention

[0005] In order to overcome the above-mentioned defects, the present invention provides a metal wire mesh weaving machine and weaving process, which solves the technical problem in the related art that the machine is stopped to replace the winding roller, which affects the production efficiency.

[0006] According to one aspect, at least one embodiment of the present invention provides a metal wire mesh weaving machine, comprising a frame and a warp shaft, a heald frame, a weft guide mechanism, a weft beating mechanism and a winding roller arranged in sequence on the frame. The warp shaft is arranged on the frame to rotate around a direction perpendicular to the warp feeding direction, and the heald frames have at least two, which are arranged on the frame to be lifted and lowered close to or away from each other. A roller changing disk is also rotatably provided on the frame, and the rotation axis of the roller changing disk is parallel to the rotation axis of the warp shaft. The roller changing disk is provided with a plurality of rotatable winding rollers distributed at intervals along the circumference, and the rotation axis of the winding roller is parallel to the rotation axis of the roller changing disk. The outer peripheral wall of the winding roller has a card groove opening toward the outside, and the inner side wall of the card groove is provided with a clamping mechanism. A cutting knife is provided above the roller changing disk, and the cutter is used to drive the metal mesh to press down into the card groove and cut it after passing through the clamping mechanism. The clamping mechanism is used to clamp the metal mesh after the cutter is separated from the card groove for winding.

[0007] For example, at least one embodiment of the present disclosure provides a wire mesh weaving machine, wherein two inner side walls opposite to each other of the card slot each have a groove opening facing outward, and the clamping mechanism includes two elastic members respectively arranged in the two grooves, and two clamping plates respectively arranged on the two elastic members, the elastic members are used to provide a force to bring the two clamping plates closer to each other, and the two clamping plates are used to clamp the metal mesh after the cutter is disengaged.

[0008] For example, at least one embodiment of the present disclosure provides a wire mesh weaving machine, wherein the roller changing disk is provided with a support mechanism on the side close to the winding roller, the winding roller is hollow inside, and has an avoidance opening at one end close to the support mechanism, and the support mechanism includes a mounting plate rotatably arranged on the roller changing disk, a guide column arranged on the mounting plate, and two support plates located at both ends of the mounting plate and arranged on the guide columns for moving closer to or away from each other, the rotation axis of the mounting plate is parallel to the rotation axis of the roller changing disk, and the two support plates are configured to support the inner circumferential wall of the winding roller after moving away from each other and follow the rotation of the mounting plate to drive the winding roller to rotate, or to cancel the support of the inner circumferential wall of the winding roller after approaching each other and follow the rotation of the mounting plate to align with the avoidance opening, and then disengage from the winding roller from the avoidance opening.

[0009] For example, at least one embodiment of the present disclosure provides a wire mesh weaving machine, wherein the support mechanism also includes a swing plate rotatably arranged on the mounting plate and coaxial with the mounting plate, two connecting rods are hingedly arranged at both ends of the swing plate, and the other ends of the two connecting rods are hingedly arranged on the two support plates, and the swing plate is configured to drive the two support plates to move closer to or away from each other after swinging.

[0010] For example, at least one embodiment of the present disclosure provides a wire mesh weaving machine, in which the inner circumferential wall of the winding roller has two limiting grooves located on both sides of the avoidance opening and distributed at an angle thereto, the openings of the two limiting grooves face inward, and the two support plates move away from each other and respectively enter the two limiting grooves to limit the support plates circumferentially.

[0011] For example, at least one embodiment of the present disclosure provides a wire mesh weaving machine, wherein a limiting block is provided on the bottom wall of the two limiting grooves, and the two support plates are correspondingly provided with a receiving groove with an opening facing outward. After the two support plates move away from each other, they respectively enter the two limiting grooves, so that the limiting block enters the receiving groove to axially limit the support plates.

[0012] For example, in at least one embodiment of the present disclosure, a wire mesh weaving machine is provided, wherein two baffles are provided on the outer peripheral wall of the winding roller so as to move closer to or away from each other, and the baffles are located inside the avoidance opening.

[0013] For example, in at least one embodiment of the present disclosure, a wire mesh weaving machine is provided, wherein two roller changing disks are provided at intervals, and a plurality of the winding rollers are provided between the two roller changing disks.

[0014] For example, in at least one embodiment of the present disclosure, a wire mesh weaving machine is provided, wherein the roller changing disc is further provided with a plurality of rotating driving members corresponding to the mounting plate, and the rotating driving members are drivingly connected to the mounting plate.

[0015] For example, at least one embodiment of the present disclosure provides a metal mesh weaving process, using any one of the metal mesh weaving machines described above, further comprising the following steps: S1. Let-off: The warp beam rotates perpendicular to the direction of let-off to deliver the warp yarn. S2, shedding: at least two heald frames move upward and downward towards or away from each other to form a lench in the warp yarns; S3, weft guide: the weft guide mechanism introduces the weft into the twist mouth; S4, beating-up: The beating-up mechanism beats the weft yarn introduced into the thong toward the weft to form a metal mesh; S5. Curling: The roller changing disk rotates around its rotation axis, and moves the circumferentially spaced winding rollers to the winding position in sequence. The lifting cutter drives the metal mesh to press down into the outward-opening slot on the outer wall of the winding roller. After the metal mesh passes through the clamping mechanism on the inner wall of the slot, the cutter cuts the metal mesh. After the cutter disengages from the slot, the clamping mechanism clamps the metal mesh, and the winding roller winds the metal mesh. When the winding roller needs to be replaced, the roller changing disk rotates to move the wound winding roller away from the winding position, and moves the new winding roller to the winding position. The wound winding roller is disengaged from the support mechanism and replaced.

[0016] The beneficial effects of the embodiments of the present invention are: The present invention improves production efficiency. By arranging multiple winding rollers on the roller changing plate and cooperating with the cutter and clamping mechanism, roller changing can be achieved without stopping the machine, so that the weaving and winding processes of the metal mesh can be carried out continuously, avoiding production interruptions caused by stopping the machine to change rollers, and significantly improving production efficiency.

[0017] Enhanced winding stability. The grooves and clamping mechanism on the outer wall of the winding roller effectively clamp the metal mesh for stable winding. The elastic clips and anti-slip grooves of the clamping mechanism increase friction with the metal mesh, preventing it from slipping during winding and ensuring winding quality.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

[0021] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0023] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

Therefore, it should not be understood as a limitation on the present invention.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] like Figures 1 to 3 The figure shows a wire mesh weaving machine according to one embodiment of the present invention. In some examples, before the wire mesh weaving machine is started, the warp beam 2 is fixed to the machine frame 1, with the warp yarns neatly wound around it, awaiting warp let-off. Multiple heald frames 3 are positioned close to each other in their initial positions, and the weft guide mechanism 4 and the beating-up mechanism 5 are also in a ready state. Multiple winding rollers 6 on the roller-changing disk 7 are evenly spaced along the circumference, and each winding roller 6 is in a ready state. At this point, the cutter 9 is positioned at its initial height above the roller-changing disk 7. After the weaving machine is started, the warp beam 2 rotates perpendicular to the warp let-off direction, evenly delivering the warp yarns. The warp yarns pass through the meshes of the heald frames 3 in a specific sequence. As the two heald frames 3 alternate up and down, the warp yarns are separated into two upper and lower pieces, forming a hank. The weft guide mechanism 4 shuttles horizontally across the hank, drawing the weft yarns into the hank, maintaining weft tension, and cutting the weft yarns. The beating-up mechanism 5 oscillates back and forth, smoothly pushing the introduced weft yarns onto the weft fell, gradually weaving the wire mesh into shape.

[0027] When the amount of metal mesh collected on one of the winding rollers 6 reaches a certain amount, the roller changing operation begins. The roller changing disk 7 rotates, and the next empty winding roller 6 is rotated to the position below the cutter 9. The cutter 9 descends, driving the metal mesh downward into the slot 61 on the outer wall of the empty winding roller 6. After the metal mesh passes through the clamping mechanism 8, the cutter 9 cuts the metal mesh. After the cutter 9 disengages from the slot 61, the clamping mechanism 8 quickly clamps the metal mesh and starts winding. At the same time, the previous winding roller 6 can be disassembled and replaced with a new one. The weaving machine does not need to be shut down during the entire process, and the metal mesh weaving and winding work continues.

[0028] The clamping mechanism 8 utilizes, for example, an elastic clip structure with anti-slip grooves on the inside. When the metal mesh passes through the clamping mechanism 8, the downward pressure of the cutter 9 causes the metal mesh to open the clip. After the cutter 9 cuts through the metal mesh and leaves the clamping slot 61, the clip quickly returns to its original position under the elastic action, firmly clamping the metal mesh. The anti-slip grooves increase the friction between the clip and the metal mesh, ensuring that the metal mesh does not slip during the winding process.

[0029] For example, the benefits of this setup are: Improve production efficiency. The arrangement of multiple winding rollers 6 on the roller changing plate 7 and the coordinated operation of the cutter 9 and the clamping mechanism 8 enable roller changing without stopping the machine, allowing the weaving and winding of the metal mesh to proceed continuously, avoiding production interruptions caused by stopping the machine to change rollers, and significantly improving production efficiency.

[0030] Enhanced winding stability. The slots 61 on the outer wall of the winding roller 6 and the design of the clamping mechanism 8 effectively clamp the metal mesh and ensure stable winding. The elastic clips and anti-slip grooves of the clamping mechanism 8 increase friction with the metal mesh, preventing the metal mesh from slipping during winding and ensuring winding quality.

[0031] like Figures 1 to 4 As shown, it shows a wire mesh weaving machine in one embodiment of the present invention. In some examples, when the weaving machine is operating normally, the metal mesh is gradually woven into shape and reaches the curling process, the cutter 9 descends to drive the metal mesh downward and enter the card slot 61. In the process of entering the card slot 61, the metal mesh will push open the two clamps 82, causing the elastic member 81 to be compressed. After the cutter 9 cuts off the metal mesh and disengages from the card slot 61, the elastic member 81 releases its elastic potential energy, driving the clamp 82 to quickly reset and tightly clamp the metal mesh. In this process, the texture on the surface of the clamp 82 is in close contact with the metal mesh, increasing friction and ensuring that the metal mesh will not loosen and slip when the winding roller 6 rotates and rewinds.

[0032] For example, the benefits of this setup are: Providing reliable clamping force. The clamping mechanism 8, consisting of an elastic member 81 and a clamping plate 82, can quickly clamp the metal mesh after the cutter 9 is disengaged, providing reliable clamping force. The elastic potential energy of the elastic member 81 ensures that the clamping plate 82 fits tightly against the metal mesh, effectively preventing the metal mesh from loosening and slipping during the winding process, ensuring winding quality.

[0033] like Figures 1 to 6 FIG. 1 illustrates a wire mesh weaving machine according to one embodiment of the present invention. In some examples, during assembly of the wire mesh weaving machine, a support mechanism 10 is mounted on the side of the roller-changing disc 7 near the winding roller 6. A rotating component is provided on the roller-changing disc 7 for mounting a mounting plate 101, ensuring that the mounting plate 101 can rotate smoothly about an axis parallel to the rotation axis of the roller-changing disc 7. A guide post 102 extends through the mounting plate 101, providing guidance for two support plates 103. Initially, the two support plates 103 approach each other and enter the interior of the winding roller 6 through the clearance 62. Then, during rotation, they become displaced from the clearance 62. Finally, the two support plates 103 move away from each other, supporting the inner wall of the winding roller 6. The support plates 103 are made of a wear-resistant material with a certain curvature, allowing them to better conform to the inner circumference of the winding roller 6. As the support plates 103 contact and tighten with the inner circumference of the winding roller 6, the mounting plate 101 rotates, driving the winding roller 6 to rotate synchronously through the support plates 103, thereby beginning to wind the wire mesh.

[0034] When the metal mesh on the winding roller 6 is wound up and the winding roller 6 needs to be replaced, the roller changing disk 7 rotates first, and the empty winding roller 6 is rotated to the winding position, and the winding roller 6 that has been wound up is rotated to the roller changing position. The winding roller 6 that has been wound up is first rotated to a position where the avoidance opening 62 is facing upward, and then a lifting roller can be arranged below it. After the roller supports the winding roller 6, the driving device causes the two support plates 103 to move closer to each other on the guide column 102. The support plate 103 gradually cancels the support for the inner wall of the winding roller 6, and then gradually aligns with the avoidance opening 62 under the rotation of the following mounting plate 101. At this time, the roller descends, and the winding roller 6 can be separated from the support plate 103. After the winding roller 6 is removed, an empty winding roller 6 is loaded, and then the roller rises. The support plate 103 rotates to a position offset from the avoidance opening 62, and then supports the winding roller 6 again, completing the replacement of the winding roller 6.

[0035] For example, the benefits of this setup are: Stable drive and support. The support mechanism 10 can provide stable support and drive for the winding roller 6. The support plate 103 supports the inner wall of the winding roller 6 and drives it to rotate, ensuring the smooth operation of the winding roller 6 during the winding process. This helps to improve the winding quality of the metal mesh and avoid problems such as uneven winding of the metal mesh caused by the shaking of the winding roller 6.

[0036] Efficient and convenient roller replacement. A fast and efficient roller replacement operation is achieved. Without stopping the machine, the roller 6 can be smoothly replaced by separating and combining the support plate 103 and the roller 6, greatly improving the production efficiency of the braiding machine and reducing the production interruption time caused by roller replacement.

[0037] like Figures 1 to 6 FIG. 1 shows a wire mesh weaving machine according to an embodiment of the present invention. In some examples, a mounting plate 101 is rotatably mounted on a roller-changing plate 7. A swing plate 104 is coaxial with the mounting plate 101 and is located in the middle. Connecting rods 105 at both ends of the swing plate 104 are hingedly connected to the two support plates 103. When the support plates 103 need to be extended or retracted, an external drive, such as a motor, is used to swing the swing plate 104.

[0038] For example, the benefits of this setup are: The movement of the support plates 103 can be controlled synchronously by simply and synchronously through the linkage structure of the swing plate 104 and the connecting rod 105 , so that the movement of the two support plates 103 moving closer to or away from each other can be controlled synchronously, thereby achieving the support and separation operation of the winding roller 6 .

[0039] like Figures 1 to 7As shown, it shows a wire mesh weaving machine in one embodiment of the present invention. In some examples, during the assembly stage of the wire mesh weaving machine, on the inner circumferential wall of each winding roller 6, limiting grooves 63 are processed on both sides of the avoidance opening 62, and the limiting grooves 63 are distributed at an angle to the avoidance opening 62, and the limiting grooves 63 open to the inside.

[0040] The mounting plate 101 rotates, driving the support plate 103 to approach the winding roller 6. As the support plates 103 move away from each other, they align with and enter the two limiting grooves 63 on the inner circumferential wall of the winding roller 6. For example, the limiting grooves 63 and the avoidance opening 62 are distributed at a 45° angle, and the support plate 103 is designed to be adapted to the limiting grooves 63. When the support plate 103 enters the limiting grooves 63, the two fit tightly together. At this time, the mounting plate 101 continues to rotate, driving the winding roller 6 to rotate synchronously through the support plate 103, and the winding of the metal mesh begins. During the winding process, due to the circumferential limiting effect of the limiting grooves 63 on the support plate 103, no relative circumferential displacement occurs between the winding roller 6 and the support plate 103, thereby ensuring the stability and uniformity of the winding.

[0041] For example, the benefits of this setup are: Improved winding stability. The circumferential limiting effect of the limiting groove 63 on the support plate 103 effectively prevents relative circumferential displacement between the winding roller 6 and the support plate 103 during rotation. This ensures that the winding roller 6 can stably rotate with the support mechanism 10 during winding, avoiding problems such as uneven winding and wrinkling of the metal mesh caused by relative displacement, greatly improving the winding quality and stability of the metal mesh.

[0042] Ensure roller changing accuracy. The coordination between the limiting groove 63 and the support plate 103 makes the roller changing process more accurate and reliable. The support plate 103 can accurately enter and exit the limiting groove 63, providing clear position indication and rotation angle for the roller changing operation, reducing errors and uncertainties during the roller changing process, ensuring smooth roller changing without stopping the machine, and improving the production efficiency of the braiding machine.

[0043] like Figures 1 to 7 As shown, it shows a wire mesh weaving machine in one embodiment of the present invention. In some examples, as the mounting plate 101 rotates, the support plates 103 move away from each other, align with each other and gradually enter the limiting groove 63. When the support plate 103 completely enters the limiting groove 63, the limiting block 631 is just embedded in the receiving groove 1031 on the support plate 103. This design ensures that the limiting block 631 is tightly fitted with the receiving groove 1031, thereby achieving axial limitation of the support plate 103. In the process of the winding roller 6 rotating to wind up the metal mesh, even if it is subjected to forces from different directions, such as the axial tension generated when the metal mesh is wound, the support plate 103 will not move axially in the limiting groove 63, thereby ensuring the stable rotation of the winding roller 6 and the uniform winding of the metal mesh.

[0044] For example, this arrangement offers the advantage of enhanced axial stability. The cooperation between the stopper 631 and the receiving groove 1031 provides reliable axial positioning for the support plate 103, effectively preventing axial movement of the support plate 103 within the stopper 63. This enables the winding roller 6 to withstand various axial forces and maintain stable rotation during the metal mesh winding process, significantly improving winding quality and preventing problems such as uneven winding or damage to the metal mesh caused by axial displacement.

[0045] like Figures 1 to 7 FIG. 1 shows a wire mesh weaving machine according to an embodiment of the present invention. In some examples, when the weaving machine is started, the wire mesh begins to wind up on the winding roller 6. As the wire mesh continues to wind, two baffles 64 maintain a constant constraint on the edges of the wire mesh. Both baffles 64 are located between the two avoidance openings 62 and do not interfere with the support plate 103.

[0046] For example, this arrangement has the advantage of improving winding quality. The two baffles 64 can effectively restrain the edges of the metal mesh, preventing the metal mesh from shifting, wrinkling, or loosening during the winding process, making the wound metal mesh more neat and compact, improving the winding quality, and providing a better product shape for subsequent use of the metal mesh.

[0047] like Figures 1 to 7 As shown, it shows a metal wire mesh weaving machine in one embodiment of the present invention. In some examples, the rotating driving member 11 can be driven by an existing motor or the like.

[0048] like Figures 1 to 7 FIG. 1 shows a metal mesh weaving process according to an embodiment of the present invention, which in some examples includes the following steps: S1, let-off: the warp beam 2 rotates perpendicular to the direction of let-off to deliver the warp yarn; S2, shedding: at least two heald frames 3 are raised and lowered toward or away from each other to form a lench in the warp yarns; S3, weft guiding: the weft guiding mechanism 4 guides the weft into the twist mouth; S4, beating up: the beating up mechanism 5 beats the weft yarn introduced into the thong toward the weft to form a metal mesh; S5. Curling: The roller-changing disc 7 rotates around its axis of rotation, and moves the circumferentially spaced winding rollers 6 to the winding position in sequence. The lifting cutter 9 drives the metal mesh to press down into the card slot 61 on the outer wall of the winding roller 6, which is open to the outside. After the metal mesh passes through the clamping mechanism 8 on the inner wall of the card slot 61, the cutter 9 cuts the metal mesh. After the cutter 9 disengages from the card slot 61, the clamping mechanism 8 clamps the metal mesh, and the winding roller 6 winds the metal mesh. When the winding roller 6 needs to be replaced, the roller-changing disc 7 rotates to move the wound winding roller 6 away from the winding position, and moves the new winding roller 6 to the winding position. The wound winding roller 6 is disengaged from the support mechanism 10 and replaced.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
