[0036] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0037] The present invention relates to an improvement in the processing method of a fan mesh cover, and proposes a processing mechanism for wire winding of a fan mesh cover. The processing mechanism directly winds the metal wire in a wire winding groove 6 on the wire winding frame 4 and embeds it in the limiting opening 7 through the arrangement of a wire winding frame 4 and a limiting opening 7 during processing, and then welds the ribs 31. In this way, the processing accuracy and processing efficiency of the fan mesh cover are greatly guaranteed. At the same time, through the arrangement of a turntable 5a, after the processing is completed, it is only necessary to rotate the turntable 5a to move the wire winding frame 4, drive the grille 30 to disengage from the limiting opening 7, and conveniently separate the prepared fan mesh cover from the wire winding frame 4, and demoulding is very convenient.

[0038] See also Figure 1-6 As shown, a processing mechanism for wire winding of a fan mesh cover is shown, wherein the fan mesh cover includes a plurality of grilles 30 arranged in an annular manner and gradually increasing in diameter, a plurality of ribs 31 for connecting the plurality of grilles 30, and the processing mechanism includes a machine table 1, a carrier frame 2 arranged on the machine table 1, a plurality of bearing seats 3 arranged circumferentially around the bearing frame 2, a wire winding frame 4 slidable in the length direction of the bearing seat 3 and arranged in each bearing seat 3, a driving assembly 5 for driving the wire winding frame 4 to slide, a plurality of wire winding grooves 6 formed on each wire winding frame 4, and a limit opening 7 located at one end of the wire winding groove 6;

[0039] The wire rack 4 has a first position and a second position on its sliding path. When the wire rack 4 is in the first position, the grille 30 is embedded in the limiting opening 7; when the wire rack 4 is in the second position or a position other than the first position and the second position, the grille 30 is disengaged from the limiting opening 7.

[0040] When in use, a plurality of metal wires are sequentially coiled in the corresponding wire winding grooves 6 and the wire winding frame 4 is driven to slide to the first position, so that the metal wires are firmly embedded in the limiting openings 7, and a plurality of annular grilles 30 with fixed positions are obtained, and then the ribs 31 are welded to the grilles 30. In this way, the spacing between adjacent grilles 30 is ensured to be consistent, and the welding stability of the ribs 31 is ensured, thereby ensuring the processing accuracy and processing efficiency of the fan mesh cover;

[0041] After the production is completed, the wire rack 4 is driven to slide toward the second position, so that the grille 30 is separated from the limiting opening 7. At this time, the welded fan grille can be conveniently removed.

[0042] In this embodiment, combined with Figure 1 and Figure 4 As shown, the supporting frame 2 includes an inner frame 2a coaxially connected to the machine 1, an outer frame 2b concentrically arranged with the inner frame 2a and having a diameter larger than the inner frame 2a, the supporting seat 3 extends along the radial direction of the grid 30 and its two ends are respectively connected to the inner frame 2a and the outer frame 2b, the length direction of the wire coiling frame 4 is consistent with the length direction of the supporting seat 3, and the wire coiling grooves 6 are arranged at intervals along the length direction of the wire coiling frame 4.

[0043] Furthermore, the processing mechanism further includes a plurality of wire coiling teeth 8 arranged on the wire coiling frame 4 at intervals along the length direction of the wire coiling frame 4, and the wire coiling teeth 8 are recessed inwardly on one side in the length direction of the wire coiling frame 4 to form a limiting opening 7, and a wire coiling groove 6 is formed between each two adjacent wire coiling teeth 8. Here, the plurality of limiting openings 7 are respectively formed on the same side of the corresponding wire coiling teeth 8.

[0044] like Figure 2-3 and Figure 5-6 As shown, the driving assembly 5 includes a turntable 5a rotatable around its own axis and arranged on the machine 1, a driving handle 16 for driving the turntable 5a to rotate, and a plurality of first slide grooves 5b arranged on the turntable 5a around the circumference of the turntable 5a. Here, the turntable 5a is located between the machine 1 and the inner frame 2a, and the three are coaxially connected in sequence, and the driving handle 16 passes through the inner frame 2a and is connected to the turntable 5a.

[0045] The wire coiling rack 4 has a slider 4a at the lower part of one end close to the machine platform 1. The slider 4a is slidably disposed in the first slide groove 5b.

[0046] Furthermore, the first slide groove 5b includes a slide groove body 5b1, a first limit end 5b2 and a second limit end 5b3 respectively located at both ends of the slide groove body 5b1, a plurality of first limit ends 5b2 are arranged at intervals to form a first circular ring 9, a plurality of second limit ends 5b3 are arranged at intervals to form a second circular ring 10, the first circular ring 9 and the second circular ring 10 are concentrically arranged and have different diameters; in this example, the diameter of the first circular ring 9 is greater than the diameter of the second circular ring 10.

[0047] The first limiting end 5b2 and the second limiting end 5b3 constituting the same first slide groove 5b respectively have a first connecting line 11 and a second connecting line 12 between the disk surface of the turntable 5a and the disk center of the turntable 5a, and an angle a is formed between the first connecting line 11 and the second connecting line 12, wherein 0°<a<180°.

[0048] When the slider 4a is located at the first limit end 5b2, the wire rack 4 is in the first position; when the slider 4a is located at the second limit end 5b3, the wire rack 4 is in the second position.

[0049] In this way, the inclination of the slide groove body 5b1 is achieved by the position difference between the first limit end 5b2 and the second limit end 5b3. When the turntable 5a rotates, the inclined slide groove body 5b1 can drive the slider 4a to move obliquely, and convert the circular motion of the turntable 5a into the linear motion of the wire rack 4, thereby driving the wire rack 4 to slide along the length direction of the supporting seat 3.

[0050] Furthermore, combined with Figure 3 and Figure 6 As shown, the two sides of the slide groove body 5b1 are respectively provided with a straight first groove wall 5b4 and an arc-shaped second groove wall 5b5, one of the two opposite sides of the slider 4a abuts against the first groove wall 5b4, and a gap is formed between the other and the second groove wall 5b5. In this example, the second groove wall 5b5 is located on the side of the first groove wall 5b4 close to the center of the rotating disk 5a. The first groove wall 5b4 is used to guide the movement of the slider 4a, and the second groove wall 5b5 is used to provide a sliding support for the slider 4a.

The processing mechanism of this example also includes a plurality of through holes 17 opened on the bearing plates 3a, a plurality of long holes 18 opened on the wire coil frame 4 and corresponding to the plurality of through holes 17, and bolts (not shown in the figure) passed through the corresponding through holes 17 and the long holes 18. The long holes 18 are used as sliding guides to realize the sliding of the bolts in the long holes 18, thereby driving the wire coil frame 4 to slide in the second slide groove 3b.

[0053] Furthermore, the processing mechanism also includes a plurality of clamping seats 13 arranged on the inner frame 2a around the circumference of the inner frame 2a, a clamping slot 14 opened on the upper part of the clamping seat 13, and a plurality of positioning posts 15 arranged on the outer frame 2b around the circumference of the outer frame 2b, and one end of the rib 31 is clamped in the clamping slot 14, and the other end has a rib ring, and the rib ring is sleeved on the positioning post 15. In this way, by fixing the two ends of the rib 31 to the inner frame 2a and the outer frame 2b respectively, the welding stability between the rib 31 and the grille 30 is ensured.

[0054] In this embodiment, two wire coiling racks 4 are arranged between every two adjacent ribs 31 , and the first sliding grooves 5 b corresponding to the two wire coiling racks 4 are arranged adjacent to each other.
