[0024] 1. By adopting high-temperature plastic coating, weaving, and heat setting, a metal-plastic molecular-level composite interface is constructed.

[0025] 2. Weave the rolled stainless steel wire into a mesh and thread it through the support mechanism. Then, use the electric push rod to pull the moving disk closer to the rotating rod. As a result, the three support bars move away from the rotating rod synchronously to support the rolled stainless steel wire mesh. Next, roll one end of the plastic film onto the side of the stainless steel wire mesh. Then, drive the driving gear to rotate by the motor. The rotation of the driving gear causes the driven gear to rotate, and thus the rotating rod rotates. The rotation of the rotating rod causes the stainless steel wire mesh to roll the plastic film outside itself, and the wrapping mechanism can drive the plastic film to move back and forth, thereby completing the wrapping of the entire outer side of the stainless steel wire mesh. After wrapping, retract the three support bars, and then wind the excess parts of the plastic film at both ends of the stainless steel wire mesh. Thus, the wrapping of the entire stainless steel wire mesh is completed. Through this structural design, it can flexibly adapt to the support and fixation of different mesh cores and can complete the comprehensive wrapping of the mesh.

[0026] 3. The use of the drive assembly is to drive the second gear to rotate through the transmission belt. Thus, the second gear drives the first gear to rotate. The rotation of the first gear causes the turntable to rotate. The rotation of the turntable causes the dial rod to come into contact and cooperate with the Geneva wheel, completing the intermittent rotation of the Geneva wheel, and thus causing the reciprocating screw rod to rotate intermittently. Therefore, when winding the plastic film on the stainless steel wire mesh, the placement rack can move intermittently periodically, so as to wind a certain thickness of plastic film on the outside of the stainless steel wire mesh.

[0038] Embodiment 1

[0039] The embodiment of the present invention discloses a method for weaving a stainless steel wire mesh, including the following steps:

[0040] S1. Provide a stainless steel wire substrate with a diameter of 0.05 - 0.15 mm;

[0041] S2. Co-extrude and wrap an anti-aging plastic layer with a thickness of 0.1 - 0.3 mm on the surface of the stainless steel wire substrate through an extruder, the wrapping treatment temperature is 180 - 220 °C, and the duration is 3 - 5 min;

[0042] S3. Weave the plastic-coated stainless steel wire through a weaving machine in warp and weft to form a plain weave mesh structure;

[0043] S4. Place the woven mesh body in an oven for high-temperature shaping. The shaping temperature is 210 - 230 °C, and the heat preservation time is 10 - 30 min.

[0044] S5. After the shaped mesh body is cooled by water to below 50 °C, it is wound up.

[0045] Specifically, in S1, the stainless steel wire substrate is 304 stainless steel wire.

[0046] Specifically, in S2, the anti-aging plastic layer is PVC or PE material added with 2 - 5 wt% ultraviolet absorber.

[0047] By adopting high-temperature plastic coating, weaving, and heat setting, a metal-plastic molecular-level composite interface is constructed. Compared with the traditional post-coating process, this technology improves the interface peel strength through high-temperature shaping at 220 °C and extends the ultraviolet aging resistance life, solving problems such as skin peeling and low-temperature embrittlement of traditional products.

[0048] Example Two

[0049] The embodiment of the present invention discloses a stainless steel wire woven mesh, and the mesh is prepared by the above-mentioned stainless steel wire mesh weaving method.

[0050] Example Three

[0051] The embodiment of the present invention discloses a plastic wrapping machine, which is used for plastic wrapping of the above-mentioned stainless steel wire woven mesh.

[0052] As Figures 1 to 7 shown, the plastic wrapping machine includes a base 1, a support mechanism 3, and a wrapping mechanism 4; a vertical plate 2 is arranged on the top of the base 1; the support mechanism 3 is rotatably arranged on the side of the vertical plate 2 and is used for supporting and fixing the stainless steel wire woven mesh; the wrapping mechanism 4 is arranged on the side of the vertical plate 2 and is used for wrapping plastic on the outer side of the stainless steel wire woven mesh.

[0053] Among them, as Figure 1 shown in Figure 2 the support mechanism 3 includes a rotating rod 300, three support bars 301, an electric push rod 302, and a motor 304; the rotating rod 300 is rotatably arranged on the side of the vertical plate 2; the three support bars 301 are all hinged to the outer side of the rotating rod 300 through movable bars, and the support bars 301 are arranged in a circular array; the electric push rod 302 is arranged on the side of the vertical plate 2, and the output end of the electric push rod 302 passes through the rotating rod 300 and is arranged outside the rotating rod 300. A moving disk 303 is arranged at the output end of the electric push rod 302, and the side ends of each support bar 301 are hinged to the outer side of the moving disk 303 through movable bars; the motor 304 is arranged on the side of the vertical plate 2, a driving gear 305 is arranged at the output end of the motor 304, a driven gear 306 is arranged at the side end of the rotating rod 300, and the driving gear 305 is meshed with the driven gear 306.

[0054] Specifically, the coiled stainless steel wire woven mesh is threaded through the support mechanism 3, and then the moving disk 303 is pulled by the electric push rod 302 to move closer to the rotating rod 300. Thus, the three support bars 301 synchronously move away from the rotating rod 300 to support the coiled stainless steel wire woven mesh. Then, one end of the plastic film is wound and attached to the side end of the stainless steel wire woven mesh. Then, the motor 304 drives the driving gear 305 to rotate, and the rotation of the driving gear 305 causes the driven gear 306 to rotate. Thus, the rotating rod 300 rotates, and the rotation of the rotating rod 300 causes the stainless steel wire woven mesh to wind the plastic film on its outer side. Moreover, the wrapping mechanism 4 can drive the plastic film to reciprocate, thereby completing the wrapping of the entire outer side of the stainless steel wire woven mesh. After wrapping, the three support bars 301 are retracted, and at this time, the excess parts of the plastic film at both ends of the stainless steel wire woven mesh are wound, thereby completing the wrapping of the entire stainless steel wire woven mesh.

[0055] Through this structural design, it can flexibly adapt to the support and fixation of different mesh cores and can complete the comprehensive wrapping of the mesh.

[0056] As Figures 1 to 4 shown, the wrapping mechanism 4 includes a mounting plate 400, a reciprocating lead screw 402, a placement rack 403, and a driving assembly; the mounting plate 400 is fixedly arranged on the top of the base 1, a cross plate 401 is arranged between the mounting plate 400 and the vertical plate 2, and a chute is opened at the top of the cross plate 401; the reciprocating lead screw 402 is rotatably arranged between the mounting plate 400 and the vertical plate 2; the placement rack 403 is slidably arranged on the cross plate 401 through a slider, and the slider passes through the chute and is threadedly connected to the reciprocating lead screw 402; the driving assembly is arranged on the side of the vertical plate 2 and is used to connect the power of the motor 304 and drive the reciprocating lead screw 402 to rotate and operate.

[0057] Specifically, the driving assembly drives the reciprocating lead screw 402 to rotate. Thus, the slider can move periodically on the reciprocating lead screw 402, thereby driving the placement rack 403 to move periodically on the cross plate 401. The placement rack 403 drives the plastic winding film to move, thereby completing the wrapping of the outer side of the stainless steel wire woven mesh.

[0058] As Figures 5 to 7 shown, the driving assembly includes a turntable 404, a grooved pulley 405, a first gear 407, and a second gear 408; the turntable 404 is rotatably arranged on the side of the vertical plate 2; the grooved pulley 405 is arranged at the side end of the reciprocating lead screw 402, and a dial rod 406 is arranged on the side of the turntable 404. The dial rod 406 can contact the groove body of the grooved pulley 405 to make the grooved pulley 405 rotate intermittently; the first gear 407 is arranged on the shaft body of the turntable 404; the second gear 408 is rotatably arranged on the side of the vertical plate 2, and the second gear 408 is meshed and connected with the first gear 407; the second gear 408 is in transmission connection with the driving gear 305 through a transmission belt.

[0059] Specifically, the driving component is used to drive the rotation of the second gear 408 through a transmission belt. Thereby, the second gear 408 drives the rotation of the first gear 407. The rotation of the first gear 407 causes the turntable 404 to rotate. The rotation of the turntable 404 causes the lever 406 to come into contact and cooperate with the Geneva wheel 405, completing the intermittent rotation of the Geneva wheel 405. Thus, the reciprocating lead screw 402 performs intermittent rotation. When the stainless steel wire is used to braid and wind the plastic film, the placement rack 403 can move intermittently periodically, so as to wind a certain thickness of plastic film on the outside of the stainless steel wire braid.

[0060] As Figure 7 shown, a plurality of concave arc grooves 409 are also formed on the outer side surface of the Geneva wheel 405, and the concave arc grooves 409 are arranged in an annular array. A semi-circular block 410 is arranged on the side surface of the turntable 404. When the lever 406 is separated from the groove on the Geneva wheel 405, the side surface of the semi-circular block 410 contacts the concave arc groove 409. This design can ensure the stability of the Geneva wheel 405 when it stops.

[0061] Specifically, the diameter of the first gear 407 is smaller than that of the second gear 408. This design can ensure the rotation speed of the reciprocating lead screw 402.
