Description

Technical Field

[0001] The utility model relates to the technical field of shielding wire braiding, in particular to a shielding wire braiding device. Background Art

[0002] Shielded cable is a transmission line that uses a metal mesh braided layer to wrap the signal line. The braided layer is generally red copper or tinned copper. Shielded cable is a wire with a metal braided shell specially used to reduce the impact of external electromagnetic fields on power or communication lines. This shielded cable also prevents the line from radiating electromagnetic energy outward.

[0003] Braided wires are generally manufactured using special braiding machines, but whether it is a horizontal braiding machine or a vertical braiding machine, the wire coils of the braided wires are often exposed, so there is a risk of dust or other impurities falling onto the braided wires. The current ways to solve this problem are mainly to regularly check and clean the braided wires and to keep the work area clean. However, the former will cause trouble in the processing procedure, and the latter requires the use of more expensive equipment such as filters, which is not conducive to convenient operation during the shielding wire braiding process.

[0004] After searching, the Chinese utility model patent with publication number CN217579265U discloses a shielded wire braiding machine, including a workbench, a braiding machine box is fixedly installed at the center position of the top of the workbench, a winding machine box is fixedly installed at the center position of the bottom of the workbench, a turntable is movably installed at the center position of the top of the workbench, a pay-off roller is fixedly installed at the outer position of the top of the workbench, and a braiding rod is fixedly connected to the top of the turntable. The process of braiding shielded wires in this application is similar to that of a vertical braiding machine, and the shielded wire braiding process is also carried out by exposing the wire coil, which will cause the risk of dust or other impurities adhering to the wire coil, and dust may have an adverse effect on the performance of the shielded wire, such as dust or other impurities will fill the gaps between the braided wires, resulting in a reduction in the coverage of the braided layer, thereby affecting the anti-interference performance of the shielded wire.

[0010] Furthermore, one side of the connecting piece is rotatably connected to a rotating rod via a damping shaft, one end of the rotating rod is fixedly connected to a knob, and two fixing pieces are respectively fixedly connected to the top and bottom ends of the rotating rod.

[0011] Furthermore, the limiting mechanism includes two fixed frames, and the top and bottom ends between the inner walls on both sides of the fixed frames are rotatably connected to the limiting rollers, and the bearing is located between the two fixed frames.

In this case, the cleanliness of the surface of the braided wire can be guaranteed, thereby preventing dust or other impurities from adhering to the braided wire and causing adverse effects on the braiding process of the shielded wire; secondly, when placing the wire coil, the sheath can be first split into a cylinder and a fixing ring, and then the outer free end of the wire coil can be led out from the notch, so the notch can be used to limit the braided wire, thereby ensuring the stability of the braiding process; in addition, the installation of the sheath only requires that the limiting rod be passed through the connecting plate, and the fixing plate be deflected to enter the incision, so the sheath can be installed quickly and conveniently, ensuring the convenience of the shielded wire braiding process.

[0015] 2. During the weaving process of the shielded wire, the limiting rollers in the two fixed frames can be used to double clamp the shielded wire, so as to provide tension for the shielded wire between the two fixed frames, ensuring that this part of the wire can always be in a straight state. In this case, weaving the shielded wire between the two fixed frames can make the braided wire more tightly wound, so as to ensure the coverage of the braided layer outside the shielded wire.

The connecting piece 8 is a supporting tool and an installation location for the sheath 4, and a winding shaft is rotatably connected to the inner wall of one side of the sheath 4. The winding shaft is used to string a wire coil of braided wire. Therefore, when its outer free end is pulled, the wire coil can rotate on the outside of the winding shaft, thereby ensuring smooth wire output.

A notch 404 is provided in the middle of one side of the support piece 402 close to the cylinder 401, and the notch 404 is used to accommodate the line body of the braided line, that is, after the end of the braided line is led out from between the cylinder 401 and the support piece 402, the support piece 402 can be pushed to buckle on the cylinder 401 after the braided line is placed in the notch 404, and thereafter the braided line will be brought out in the notch 404, and the notch 404 can provide a guiding effect for the process of bringing out the line.

[0027] Preferably, there are two limit rods 7, and the two limit rods 7 are respectively fixedly connected to the top and bottom of the side of the cylinder 401 away from the supporting piece 402, that is, the limit rod 7 is close to the connecting piece 8 and penetrates the connecting piece 8 from the positioning hole, so the fixing of the sheath 4 can be achieved by only using the fixing piece 9 to fix the rod body part of the limit rod 7 passing through the connecting piece 8, and the top and bottom of the sheet body of the connecting piece 8 are provided with positioning holes, and the two limit rods 7 penetrate the connecting piece 8 at the two positioning holes, respectively, and the cutout 701 is provided at the side of the rod body of the limit rod 7 away from the cylinder 401. One side of the connecting piece 8 is rotatably connected to the rotating rod 10 through the damping shaft, and one end of the rotating rod 10 is fixedly connected to the knob 11, and the two fixing pieces 9 are respectively fixedly connected to the top and bottom ends of the rotating rod 10, and by twisting the knob 11 to deflect the rotating rod 10, the fixing piece can be deflected to contact with the limit rod 7 and enter the cutout 701, thereby fixing the sheath 4.

[0028] Preferably, the limiting mechanism includes two fixed frames 3, and the top and bottom ends between the inner walls on both sides of the fixed frames 3 are rotatably connected to limiting rollers 301. The bearing 6 is located between the two fixed frames 3, and the shielding wire can be doubly clamped by the limiting rollers 301 in the two fixed frames 3, thereby providing tension for the wire between the two fixed frames 3 to ensure that the wire section can always be in a straight state. Therefore, when the shielding layer of the shielding wire is weaved between the two fixed frames 3, the phenomenon of loose wires in the braided layer can be avoided, so the weaving quality can be guaranteed.

[0029] Preferably, the reeling and winding mechanism includes two winding rollers 2, which are rotatably connected to the two ends of the shell 1 respectively. A driving mechanism is provided inside the shell 1, and the driving mechanism includes a motor 1 and two motors 2. The two motors 2 are respectively used to drive the two winding rollers 2 to rotate synchronously. The two motors 2 can drive them by directly connecting their own output shafts to the winding rollers 2. Motor 1 is used to drive the rotating drum 5 to rotate, and motor 1 can drive the rotating drum 5 by gear transmission or belt transmission. Specifically, two meshing gears are connected by a key on the output shaft of motor 1 and the outside of the rotating drum 5, or pulleys are connected by a key on the output shaft of motor 1 and the outside of the rotating drum 5, and the same belt is sleeved on the outside of the two pulleys.

[0030] Working principle: When using the device to weave the shielded wire, the shielded wire can be wound on one of the two winding rollers 2, and then the outer free end of the shielded wire coil is pulled to pass through the rotating drum 5 and the two fixed frames 3 between the two limiting rollers 301, and then fixed to the other winding roller 2. At this time, the two limiting rollers 301 can clamp the shielded wire to provide tension for the shielded wire, so that the shielded wire body between the two fixed frames 3 can always be in a straight state;

[0031] Then, the supporting sheet 402 can be pulled to create a gap between it and the cylinder 401, and then the coil of the braided wire is placed in the cylinder 401 and sleeved on the winding shaft, and at the same time, the outer free end of the coil of the braided wire is pulled from the gap to lead it out of the notch 404 to the outside of the cylinder 401, and then the braided wire will be in the sheath 4, so as to provide a dust-proof effect for the braided wire;

[0032] After that, the support piece 402 can be pushed to be fastened with the cylinder body 401 again, and then the sheath 4 can be pushed to be fastened on the connecting piece 8 when the two limiting rods 7 are respectively aligned with the two limiting holes. This will make the limiting rod 7 penetrate the connecting piece 8. Therefore, it is only necessary to twist the knob 11 to drive the fixing piece 9 to deflect into the cutout 701 on the limiting rod 7 through the rotating rod 10, so that the limiting rod 7 can be fixed, and then the fixing of the sheath 4 is realized;

[0033] After that, pull the outer free end of the braided wire reel and fix it on the wire body of the shielded wire. After completing the above operations, you can start motor one and the two motors two. At this time, the two motors two can respectively drive the two winding rollers 2 to rotate, thereby realizing the unwinding and winding of the shielded wire reel at the same time. At the same time, motor one can drive the rotating drum 5 to rotate, so the rotating drum 5 can drive the sheath 4 to rotate outside the shielded wire to realize the winding of the braided wire around the outside of the shielded wire, thereby achieving the effect of braiding the shielded wire.

[0034] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
