The utility model provides a low smoke and zero halogen safety cable, this cable is through the production facility preparation of a low smoke and zero halogen safety cable, and this cable body includes a plurality of cable cores, has the polytetrafluoroethylene insulating layer at the outside parcel of each cable core, and many cable cores and filling rope transposition, whole cable outside after the transposition have the waterproof layer around the package.
Specifically, the working principle of the production equipment of the low-smoke halogen-free safety cable is as follows:
and (3) tightening the filling rope at the gap:
firstly, an operator sequentially penetrates one end of a twisted cable core 6 through a first circular tube 3 and a second circular tube 5, then penetrates through four push blocks 607, then penetrates through guide assemblies, then fixes one end of the cable core 6 on an external winder, then places a wrapping tape on a material tray 403, bypasses one end of the wrapping tape through a limiting column 404, then fixes one end of the wrapping tape on the cable core 6, controls the external winder to work at the moment when the wrapping tape is in an inclined state, pulls the twisted cable core 6 backwards, so that the cable core 6 is in contact with two front clamping plates 208 and compresses a first elastic member 207, the two front clamping plates 208 clamp and limit the cable core 6 under the action of the first elastic member 207, thereby reducing the shaking of the cable core 6 during wrapping, and controls a second power motor 304 to enable a straight gear 305 to rotate, the spur gear 305 drives the gear ring 303 to rotate counterclockwise when viewed from the front to the back, the rotating ring 301, the first circular ring 302, the second connecting column 308, the second elastic member 309, the pressing block 310 and the second touching block 311 rotate synchronously with the gear ring 303, because in the prior art, the cable core 6 is generally a cable core 6 which is similar to a rope and formed by twisting a plurality of wires around a central wire, but gaps are easy to appear when the central wire and other wires are twisted, and the gaps are often filled with a filling rope, when the cable core 6 moves backwards, the filling rope moves spirally, so the rotating direction of the gear ring 303 is consistent with the rotating direction of the filling rope when the filling rope moves, and the speed is the same, when the filling rope moves to one side of the pressing block 310, the first touching block 307 contacts with the second touching block 311 along with the rotation of the gear ring 303, the second contact block 311 is pushed to move inwards, the second connecting column 308 and the pressing block 310 move synchronously along with the second contact block 311, the second elastic piece 309 is stretched, the pressing block 310 is in contact with the filling rope and pushes the filling rope to move, so that the filling rope presses a gap between the wires more tightly, the cable core 6 is more round, the roundness of the finished cable core 6 is improved, the structure of the cable core 6 is more stable, meanwhile, the bulge of the filling rope is avoided, and the problem that the subsequent wrapping effect is influenced occurs, when the first contact block 307 is separated from the second contact block 311, the second elastic piece 309 is changed from a stretching state to a normal state, the pressing block 310 drives the pressing block 310 to move outwards to reset in the process of changing the second elastic piece 309, when the toothed ring 303 continuously rotates, the first contact block 307 is matched with the second contact block 311 under the action of the second elastic piece, the pressing block 310 moves back and forth, so that the pressing block 310 pushes the filling rope to complete the inward movement of the gap of the filling rope, the entire gap is compacted by the first contact block 307, and the pressing block 208 of the filling rope, and the two clamping plates of the filling rope is further pressed by the first contact block 207, thereby preventing the filling rope from rotating, the cable core 6 from being pressed by the first contact block 310, and the pressing the cable core 6, and the clamping plate 207, and the pressing plate after the cable core 6, the cable core plate is pressed by the pressing block 208;
when pulling around cable core 6 of package:
meanwhile, the first power motor 201 is controlled to rotate the first belt pulley 202, the first belt pulley 202 drives the second belt pulley 205, the second belt pulley 205 drives the shaft sleeve 203 to rotate clockwise, the disc 204, the wrapping assembly and the touch assembly rotate synchronously along with the shaft sleeve 203, and then wrapping of the cable core 6 is realized, when the material tray 403 is positioned above the cable core 6 in the rotation process of the disc 204, the cable core 6 is pulled upwards by the wrapping belt under the action of the wrapping belt, meanwhile, the touch ball 503 pushes the wedge block 605 above downwards, the third connecting column 604 and the push block 607 above move synchronously along with the wedge block 605, the third elastic element 606 is stretched, and as the cable core 6 is positioned between the four push blocks 607 and is in contact with the push blocks 607, the push block 607 above moves downwards, therefore, the upward pulling force of the cable core 6 is counteracted, and meanwhile, the upper pushing block 607 also generates a downward pushing force on the cable core 6, so that the cable core 6 is wound more tightly by the wrapping tape, thereby avoiding that the wrapping tape is easy to have insufficient pulling force due to the shaking of the cable core 6, the wrapping of the cable core 6 is loosened, and the overall quality of the cable core 6 is influenced, when the material tray 403 rotates to the right of the cable core 6, the cable core 6 is pulled to the right by the wrapping tape under the action of the wrapping tape, and meanwhile, the touch ball 503 is in contact with the right wedge block 605 and pushes the right wedge block 605 to move to the left, the right third connecting column 604 and the pushing block 607 move synchronously with the wedge block 605, the third elastic member 606 is stretched, and then the right pushing block 607 pushes the cable core 6 to move to the left, so that the right pulling force of the cable core 6 is counteracted, meanwhile, the right pushing block 607 can generate a force pushing the cable core 6 leftwards, the process is repeated, the whole cable core 6 can be tightly wrapped under the action of the pushing block 607, when the wrapping angle of the cable core 6 needs to be changed, the electric push rod 406 is controlled to enable the first connecting plate 402 to push upwards, the first connecting plate 402 rotates upwards on the first base 401 under the limit of the first base 401, the material disc 403 and the limiting column 404 rotate synchronously along with the first connecting plate 402, and the wrapping angle of the cable core 6 can be changed;
when the wrapping tape needs to be placed, an operator pushes the protective cover 8 forwards, then unscrews the material disc 403, and then puts the wrapping tape on the material disc 403, and then pushes the protective cover 8 backwards to reset, so that the safety accidents on workers caused by the quick rotation of the material disc 403 when the cable core body 6 is wrapped are avoided under the action of the protective cover 8.
