By means of the nuts, the relative position of the adjusting screw rod and the fixed platform can be changed, and further the overall position of the two sliding seats can be adjusted. The change of the sliding seats means the change of the distance between the supporting steel wire and the plastic pipe. Thus, the production of automotive seat back grids of different specifications can be realized.

[0041] The eccentric drive wheel of the spring wire drives the upper and lower sliding of the spring wire upper tool holder through the spring wire pressure rod. When the spring wire upper cutter is driven by the spring wire upper tool holder to slide downward, the spring wire located at the spring wire lower cutter will be cut off. Among them, the reciprocating movement component can guide the wire to the forming station after the wire is cut, making the spring wire cutting module closer to the forming station, so that the spring wire can be more accurately guided to the position matched with the plastic pipe.

The lower fixing seat of the plastic pipe is vertically slidably matched with the lower part of the plastic pipe cutting base. The lower fixing seat of the plastic pipe is driven by a cylinder. The lower clamping strip is fixed to the lower fixing seat of the plastic pipe corresponding to the upper clamping strip. The upper edge of the lower clamping strip is provided with a semi-circular through groove for lower positioning of the plastic pipe corresponding to the semi-circular through groove for upper positioning of the plastic pipe. The upper edge of the lower clamping strip is provided with a spring wire positioning through groove perpendicular to the direction of the semi-circular through groove for lower positioning of the plastic pipe.

[0047] After the plastic pipe slides out a predetermined length from the plastic pipe positioning inlet hole and the plastic pipe positioning outlet hole, the plastic pipe is clamped by the upper clamping strip and the lower clamping strip. The plastic pipe is located between the semi-circular through groove for upper positioning of the plastic pipe and the semi-circular through groove for lower positioning of the plastic pipe. At this time, the cylinder drives the plastic pipe cutter to slide downwards, and the cutting edge of the plastic pipe cutter cuts off the plastic pipe. At the same time, the spring wire slides into the channel of the spring wire positioning through groove, that is, the spring wire will pass through the plastic pipe. In this way, the positioning, cutting and combination of the plastic pipe with the spring wire can be realized.

[0048] Preferably, the support wire feeding module includes a support wire fixed transmission wheel and a support wire movable transmission wheel arranged in parallel on both sides of the support wire transmission line. The support wire fixed transmission wheel and the support wire movable transmission wheel are respectively provided with support wire coaxial gears that mesh with each other.

[0049] The support wire fixed transmission wheel and the support wire movable transmission wheel provide power for the transmission of the support wire. The support wire transmission pressure adjusting components can adjust the tightness of the support wire, which is convenient for more stable transmission of the plastic pipe.

[0050] Preferably, the support wire winding module includes a support wire feeding cylinder, a wire twisting disc and a wire twisting needle;

[0051] The support wire feeding cylinder is arranged in the housing corresponding to the support wire transmission line, and the feeding port of the support wire feeding cylinder is butted with the discharging port of the support wire feeding module. A cylindrical cam is rotatably arranged on the outer periphery of the middle part of the feeding cylinder, a cam groove is arranged on the outer periphery of the cylindrical cam, and a cam follower extending into the cam groove is arranged in the housing; The discharging end periphery of the feeding cylinder is rotationally matched with the wire twisting disc, and the back surface of the wire twisting disc is butted and fixed with the front end of the cylindrical cam; The wire twisting needle is eccentrically arranged on the front surface of the wire twisting disc, and an annular positioning groove is arranged on the outer periphery of the wire twisting needle; A support is arranged in front of the wire twisting disc, and a space for the wire twisting needle to move is left between the support and the wire twisting disc.

[0052] The support wire moves out from the discharging port of the support wire feeding cylinder, and the spring wire is sent from the spring wire feeding module to the forming station. During this process, the spring wire will pass in front of the wire twisting disc. The wire twisting disc rotates, and the spring wire is wound around the support wire through the wire twisting needle, thereby realizing the winding of the spring wire around the support wire. And the use of the cam groove and the cam follower can make the wire twisting disc move axially during the rotation process, so that the electric spring wire undergoes a spiral displacement along the support wire transmission line during the wire twisting process, so as to wind the spring wire around the support wire in a spiral shape. The front end of the support rod moves out from the discharging hole of the feeding cylinder to above the support, and then the wire twisting needle drives the spring wire to wind around the periphery of the support rod. Due to the existence of the support rod, it can be avoided that the support rod is bent during the process of the spring wire winding around the support rod, affecting the parallelism of the support rod before and after in the wire curtain of the seat back.

[0053] Preferably, the support wire positioning and cutting module includes a moving table, a support wire guiding member and a support wire cutting assembly; The support wire guiding member is arranged above the moving table along the direction of the support wire transmission line, and a gap for the grid to pass through is left between the support wire guiding member and the moving table; The support wire cutting assembly is arranged on both sides of the moving table corresponding to the coated steel wire transmission line,

[0054] The support wire cutting assembly includes a support wire cutting base, a support wire eccentric driving wheel, a support wire pressing rod, a support wire upper knife seat, a support wire upper cutting knife, a support wire lower knife seat and a support wire lower cutting knife;

[0055] The upper part of the support wire cutting base is rotationally fitted with the support wire eccentric drive wheel. The upper end of the support wire pressure rod is connected to the support wire eccentric drive wheel through a bearing. The lower end of the support wire pressure rod is hinged to the support wire upper knife seat. The support wire upper knife seat is vertically slidably fitted to the support wire cutting base. The support wire upper knife is arranged downward on the support wire upper knife seat. The support wire cutting base is provided with a support wire lower knife seat corresponding to the lower side of the support wire upper knife. The support wire lower knife is arranged upward on the support wire lower knife seat. A support wire feeding pipe is arranged in the middle of the support wire cutting base. The downstream pipe orifice of the support wire feeding pipe is butted between the support wire upper knife and the support wire lower knife.

[0056] After the spring wire is cut off and cooperates with the support wire and the plastic pipe, it moves onto the moving table. The length of the support wire is determined according to the length of the grid of the automobile seat backrest, that is, after the plastic-coated part moves to the preset length, the support wire eccentric drive wheel drives the support wire upper knife seat to move downward through the support wire pressure rod, and the support wire upper knife acts on the support wire, thereby cutting off the support wire.

[0057] Advantages of the present invention:

[0058] Based on the special structures of the spring wire, the plastic pipe and the support wire of the grid of the automobile seat backrest, the spring wire transmission line, the plastic pipe transmission line and the plastic-coated pipe transmission line are arranged according to their directions. The spring wire is automatically straightened, and the spring wire, the plastic pipe and the support wire are transmitted and supplied to the forming station, and the assembly of the spring wire with the plastic pipe and the support wire is realized through the plastic pipe cutting and positioning module and the support wire winding module.
