Wire PVC Coating Line: iron wire PVC coating machine line
Wire PVC coating line is used to produce PVC insulated wire, the customer can produce insulated wire of different size by change the machine head and related accessories. The extruder and tractor apply YCT series governor motor with big range of speed adjustment; we use the intelligent temperature control instrument to control the temperature of the capstan and head automatically with high sensitivity. The structure of the production line is simple, easy to operate, safe and reliable.

Structure description:
The wire PVC coating line is vertical type and aligned in the straight line,compare with wire pay-off, wire guiding frame, extruder, machine head, watercooling groove, wire take-up and electrical controlling cabinet, etc.
1. Wire pay-off is used to de-coil the wire and feed into the wire guidingframe.
2. There is two rolling wheel on the wire guiding frame, the wire go throughthe wheel will become straight to direct it into the machine head. Anotherrolling wheel can adjust up and down to confirm the wire center is at the sameheight with the extruder center.
3. Extruder is the main part of the wire PVC coating production line and it isused for the soft PVC insulate wire. Customer can use this machine to producepipe, single wire, etc., by change the machine head and related accessories.Extruder is compared of drive system, screw, plastic capstan, plastic feedingsystem, electric heater, etc.
4. Machine head, located in the front end of the charging barrel, is the formingpart of the wire insulating layer. It is composed by mould body, core mould,mouth mould, adjusting screw, etc.
5. There are two cooling flumes, both of which are composed of inlet and outletwater pipes, water valves, flume shelf. The surface layer of the wire, which isout of the mouth mould of the machine head, is shown as soften status. So itmust be cooling shaped through cooling flume. The cooling water flows out fromthe inlet water pipes, and the wires are thoroughly hardened when they pass fromthe water current. Meanwhile, the hot water is discharged from the returnpipes. During the whole process, the cooling water is circulatory.
6. Traction engine: The power of the driven motor on the traction engine is3KW, after decreasing the speed by the speed reducer, then transmitting by thechain wheels, and then the two traction wheels could rotate. The diameter ofthe traction wheel is 600mm;the adjusting range of the traction speed is 20-200m/min. In order to prevent the wire from trackslipping when traction, the wires are wound as "S" shape in the upperand lower traction wheels, in order to increasing the friction force. Thespeed-regulating motor is controlled by the assorted speed-regulating motorcontroller.
7. Recoiling machine: The recoiling machine is driven by one set of three-phasetorque motor of YLJ132-40/4 type. This motor could keep the recoiling tensileforce the same as the recoiling diameter increasingly becomes bigger.Meanwhile, use the wire arranging unit to arrange the wires automatically, andarrange the wires to the recoiling panel. When one recoiling panel is full ofthe wires, push the handle in the rack and start another wire recoiling panel.The recoiling panels are used alternatively.
