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, and the outside parcel of every cable core has polytetrafluoroethylene insulating layer, and many cable cores are stranded with the filling rope, and the whole cable outside after the transposition is around having the waterproof layer.
Specifically, the working principle of the production equipment of the low-smoke halogen-free safety cable is as follows:
real time to fill rope at gap:
firstly, an operator passes one end of the twisted cable core 6 through the first round tube 3 and the second round tube 5 in sequence, then passes through four pushing blocks 607, then passes through the guiding components, then fixes one end of the cable core 6 on the peripheral winding device, then places the wrapping tape on the material disc 403, bypasses one end of the wrapping tape on the limit post 404, then fixes one end of the wrapping tape on the cable core 6, at this time, the wrapping tape is in an inclined state, at this time, the peripheral winding device is controlled to work, the twisted cable core 6 is pulled backwards, so that the cable core 6 contacts with the two clamping plates 208 in front and compresses the first elastic piece 207, under the action of the first elastic piece 207, the two clamping plates 208 in front clamp and limit the cable core 6, thereby reducing shake when the cable core 6 is wrapped, at the same time, the second power motor 304 is controlled to rotate the spur gear 305, the spur gear 305 drives the toothed ring 303 to rotate counterclockwise based on the front-to-back view, the rotating ring 301, the first circular ring 302, the second connecting post 308, the second elastic member 309, the pressing block 310 and the second touching block 311 rotate synchronously with the toothed ring 303, because in the prior art, the cable core 6 is the cable core 6 which is similar to a rope and is formed by twisting several wires around one central wire, but gaps are easy to occur between the central wire and other wires when twisting, and the gaps are often filled with filling ropes, so that when the cable core 6 moves backward, the filling ropes move in a spiral shape, the rotating direction of the toothed ring 303 is consistent with the rotating direction of the filling ropes, and the speed is the same, when the filling ropes move 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 toothed ring 303, the second touching block 311 is pushed to move inwards, the second connecting column 308 and the pressing block 310 move synchronously along with the second touching block 311, the second elastic piece 309 is stretched, the pressing block 310 is further contacted with the filling rope and pushes the filling rope to move, gaps between wires of the filling rope are pressed tightly by the filling rope, the cable core 6 is further round, the roundness of a finished product of the cable core 6 is improved, the cable core 6 is further stable in structure, meanwhile, the problem that the bulge of the filling rope is avoided, the effect of subsequent wrapping is affected, when the first touching block 307 and the second touching block 311 are separated, the second elastic piece 309 is changed into a normal state from a stretching state, the pressing block 310 is driven to move outwards and reset in the conversion process of the second elastic piece 309, and when the toothed ring 303 continuously rotates, the pressing block 310 is driven to reciprocate by the cooperation of the first touching block 307 and the second touching block 311, the pressing block 310 is pushed back and forth on the filling rope, and accordingly the packing rope at the whole gap is completed, the packing rope is tightly compacted tightly along with the rotation of the cable core 208, the cable core 6 is further clamped by the two clamping plates, and the two clamping plates are further clamped by the two clamping plates and the cable 6 are prevented from being further compressed and filled by the clamping plates;
when the wrapped cable core 6 is pulled:
at the same time, 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 is used as a reference from front to back, the driving sleeve 203 of the second belt pulley 205 rotates clockwise, the disc 204, the wrapping assembly and the touching assembly rotate synchronously along with the sleeve 203, thereby realizing the wrapping of the cable core 6, during the rotation of the disc 204, when the material disc 403 is positioned above the cable core 6, the cable core 6 is pulled upwards by the wrapping belt due to the effect of the wrapping belt, the touching ball 503 pushes the upper wedge block 605 to move downwards, the upper third connecting post 604 and the pushing block 607 move synchronously along with the wedge block 605, the third elastic piece 606 is stretched, the cable core 6 is positioned between the four pushing blocks 607 and is contacted with the pushing blocks 607, the upper pushing block 607 pushes the cable core 6 to move downwards, thus the upward pulling force of the cable core 6 is counteracted, meanwhile, the upper pushing block 607 also generates downward pushing force on the cable core 6, so that the cable core 6 is wound tightly by the wrapping tape, the phenomenon that the cable core 6 is loose due to insufficient pulling force when the wrapping tape is wrapped due to shaking of the cable core 6 is avoided, the whole quality of the cable core 6 is influenced, when the material disc 403 rotates to the right of the cable core 6, the cable core 6 is pulled rightwards by the wrapping tape due to the effect of the wrapping tape, meanwhile, the touching ball 503 is contacted with the right wedge-shaped block 605, the right wedge-shaped block 605 is pushed to move leftwards, the right third connecting column 604 and the pushing block 607 synchronously move along with the wedge-shaped block 605, the third elastic piece 606 is stretched, the right pushing block 607 further pushes the cable core 6 to move leftwards, the rightwards pulling force of the cable core 6 is counteracted, meanwhile, the right push block 607 also generates a force for pushing the cable core 6 leftwards, so that the whole cable core 6 can be tightly wrapped under the action of the push block 607, when the wrapping angle of the cable core 6 needs to be changed, the electric push rod 406 is controlled to push the first connecting plate 402 upwards, the first connecting plate 402 rotates upwards on the first base 401 under the limit of the first base 401, and the material disc 403 and the limit column 404 synchronously rotate along with the first connecting plate 402, so that the wrapping angle of the cable core 6 can be changed;
when needs place around the band, the operator promotes protection casing 8 forward, then unscrews material dish 403, then will wind the band put into material dish 403 on can, later with protection casing 8 backward promotion reset, under the effect of protection casing 8, avoided when wrapping cable core 6, because the fast rotation of material dish 403, and cause the emergence to the incident on the staff.
