[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0030] As Figure 1-8 shown, a single-mode double-wire chain-link fence weaving device according to an embodiment of the present invention includes a frame 1. A first adjustment platform 2 and a second loading platform 3 are sequentially arranged on the upper right side of the frame 1 along the wire outlet direction. A wire rolling shaft driving mechanism for driving a wire rolling shaft 4 is arranged on the first adjustment platform 2. Two raw material straightening mechanisms and a spiral sleeve fixture 5 are sequentially arranged on the second loading platform 3 along the wire outlet direction. A wire mesh forming and correcting mechanism is arranged on the right side of the spiral sleeve fixture 5. The output end of the wire rolling shaft 4 is connected with a guide plate 6. The guide plate 6 passes through the spiral sleeve in the spiral sleeve fixture 5. A wire mesh cutting mechanism is arranged on the left side of the end of the guide plate 6 along the wire outlet direction. A wire mesh pressing and separating mechanism is arranged on the right side of the wire mesh cutting mechanism. A net weaving unit is arranged on the left side of the wire mesh cutting mechanism. The net weaving unit includes a weaving platform 7 located on the upper end of the frame 1 and a wire mesh positioning mechanism located above the weaving platform 7.

[0031] In one embodiment of the present invention, the first adjustment platform 2 is used to install the first driving motor 8, the wire rolling shaft transmission wheel 9, etc., and can slide to adjust the position of the connecting mechanism components at its upper end; the second loading platform 3 is used to install the raw material straightening mechanism, the spiral sleeve fixture 5, etc. The specific structure has been disclosed in the patent "CN216828423U" applied by our company and will not be elaborated here.

[0032] In one embodiment of the present invention, the wire rolling shaft driving mechanism includes a first driving motor 8, a transmission belt and a wire rolling shaft transmission wheel 9. The first driving motor 8 drives the wire rolling shaft transmission wheel 9 through the transmission belt, thereby driving the wire rolling shaft 4 to rotate.

[0033] In one embodiment of the present invention, there are two raw material supports 32 on the rightmost side of the frame 1 for placing raw materials. The raw materials can be straightened by the raw material straightening mechanism. The raw material straightening mechanism includes two connecting plates one 10. The lower connecting plate one 10 is fixedly connected to the second loading platform 3, and the distance between the two connecting plates one 10 can be adjusted by the handwheel adjuster 11.

[0034] In one embodiment of the present invention, the wire forming and straightening mechanism includes a connecting seat 12. Two raw material wire adjusting columns 13 are connected to the upper end surface of the connecting seat 12 (the wire mesh coming out of the raw material straightening mechanism is wound around the guide plate 6 through the gap between the two raw material wire adjusting columns 13). A second guide column 14 is connected to the left side of the connecting seat 12. The second guide column 14 sequentially passes through the spiral sleeve fixture 5 and the connecting plate two 15. The second guide column 14 is connected to the connecting plate two 15 as a whole through the first set screw 36. The connecting plate two 15 clamps and is threadedly connected to the spiral sleeve fixture 5 through the nut of the adjusting screw 34 and the connecting plate limit nut 35. By rotating the adjusting screw 34, the position of the second guide column 14 can be driven to adjust the position of the raw material wire adjusting column 13. In addition, in order to prevent the adjusting screw 34 from loosening due to the vibration of the machine tool in this application, the adjusting screw 34 is pressed by the third set screw 38. In order to avoid the third set screw 38 pressing and locking the adjusting screw 34, a rubber pad is provided on the connection surface between the two. The rubber pad has a buffering and pressure reducing effect, and the squeezing destructive force between the two is reduced by the flexibility of the rubber pad, so that the adjusting screw 34 can be adjusted directly without loosening the third set screw 38. An avoidance groove is provided inside the connecting plate two 15, and the avoidance groove is used to avoid the guide plate 6.

[0035] In one embodiment of the present invention, the wire pressing and separating mechanism includes a connecting plate III 18 with an L-shaped structure. One plate surface of the connecting plate III 18 is fixedly connected to the upper right side surface of the sliding tool holder 16, and the other plate surface (the bolt holes on this plate surface are long holes, which can adjust the position of the wire bending plate 19 to a certain extent) is connected to the wire bending plate 19 by bolts. In the middle of the upper end surface of the wire bending plate 19, there is a sliding rod, and a sliding sleeve 21 is movably connected to the sliding rod. The top of the sliding rod is connected to a spring pressing plate 22, and a spring is arranged between the sliding sleeve 21 and the spring pressing plate 22. The left side surface of the sliding sleeve 21 is connected to an expansion plate 23. The lower end of the expansion plate 23 is of a triangular structure. There are two limiting rings 20 (limiting two wires) on the right side of the wire cutting mechanism. When the sliding tool holder 16 moves downward, that is, when the cutting knife 17 cuts the wire downward, the connecting plate III 18 moves downward accordingly. Then, the expansion plate 23 uses the triangular tip at the lower end to cut into the left side of the intersection of the two wires, separating the two wires to both sides. Naturally, the intersection of the wires at the cutting knife position also separates to both sides, placing the two wires respectively under the misaligned cutting edges of the cutting knife to achieve separate and sequential cutting of the two wires.

[0036] In one embodiment of the present invention, a cutting knife 17 is connected to the upper left side surface of the sliding tool holder 16. The cutting knife 17 includes a first cutting edge 17-1 and a second cutting edge 17-2. The first cutting edge 17-1 and the second cutting edge 17-2 are in an upper and lower misaligned structure (the upper and lower positions of the first cutting edge 17-1 and the second cutting edge 17-2 can be interchanged and set accordingly according to the cutting knife 17 and the wire outlet position). Since the two wires cross one above the other, the cutting edges are divided into two parts with an upper and lower misaligned structure to cut the two wires separately and successively, thereby reducing the motor power and consumption cost, achieving a certain energy-saving and consumption-reducing effect. The lower part of the sliding tool holder 16 is connected to the eccentric arm of the cutting knife power source through a connecting rod. The sliding tool holder drives the connecting rod to move up and down by the eccentric arm of the cutting knife power source rotating, thereby driving the sliding tool holder 16 to move up and down to achieve the purpose of cutting the wire. The cutting knife power source is placed under the weaving platform 7 facing the frame 1. This method avoids the potential danger caused by the dripping of lubricating fluid to the power source.

[0037] In one embodiment of the present invention, a baffle 24 is connected to the inner side of the weaving platform 7 by screws. The baffle 24 is of an L-shaped structure. There are several long through holes I 24-1 on the connecting plate surface of the baffle 24. The baffle 24 plays a role in standardizing the wire weaving direction and restricting the forming and weaving of the wire. Due to the presence of the long through holes I 24-1, when it is necessary to adjust the position of the baffle 24, loosen the screws locking the baffle 24, move it back and forth to the appropriate position, and then lock it with screws.

[0038] In one embodiment of the present invention, the second driving motor 28 drives the hoisting shaft 25 to rotate through a transmission mechanism, thereby driving the hoisting wheel 26 to rotate. The rotation of the hoisting wheel 26 drives the net needle 27 to move through a chain, thereby realizing the knitting action of the net needle. For the specific transmission structure and principle, please refer to the patent with the application number "2022219272826" applied by our company.

[0039] In one embodiment of the present invention, the net needle 27 is fixedly connected to the connecting support 29 through the fifth connecting plate 33. The hoisting shaft 25 is connected to the connecting support 29 through a bearing 30. The second driving motor 28 is connected to the connecting support 29 through a motor support. The connecting support 29 is connected to the bracket 31 through bolts. In this application, the net needle 27 (including the net needle fixing device and the net needle adjusting device), the hoisting shaft 25, and the second driving motor 28 are all connected to the connecting support 29 to form an integral body. The bottom surface of the connecting support 29 is provided with a second long through hole. When it is necessary to adjust the entire net surface positioning mechanism, only need to loosen the fixing screws, move the connecting support 29, and finally lock and fix it by passing the fixing screws through the second long through hole. The adjustment is very convenient and there is no need to separately adjust and connect them.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
