630/6+12+18+24 Spool Rigid Frame Strander With Side Load Bobbin System.
This machine is mainly suitable for the production of large-length bare aluminum, bare copper wire and steel-cored aluminum stranded wire and aluminum alloy wire and fan-shaped conductor twisted and pressed, round conductor twisted and drawn tight. The equipment adopts 36-level traction gearbox, double active and double traction devices, and the splitter wheel adopts natural branching to avoid the wire core wiping during the stranding process. The tension of the device is controlled by pneumatic tension to ensure the coil is full. The fully-disconnected automatic parking device with uniform tension when empty and with a unique function, the disconnected parking is directly controlled to each of the pay-distribution discs, and the host automatically stops immediately when the disconnected disc is stopped.

3.1.1 Using end shaft thimble type, electric lift, electric clamping.
3.1.2 The tension tension control adopts mechanical butterfly tension, and the size of the tension can be adjusted manually.
3.2 6/12/18/24 bobbin stranding cage
3.2.1 An adjustable single core pre distortion device is installed at the front end of each cage. The cage body is driven by the ground shaft drive cage toothbox. The operation handle can realize the forward and backward rotation and idle rotation of the cage. The handle is easy to change gears. The 6-stage speed change of each main engine can be adjusted.
3.2.2 When concentrating on the bobbins, the cage is rotated and positioned by a single motor.The main motor and the loading bobbins motor are connected by clutch.The clutch controls the rotation of the motor and the loading bobbins motor respectively through two stroke switches during commutation.
3.2.3 The position of the loading bobbins of the frame is controlled by the contact and proximity switch on the frame. The brake is completed by four groups of positioning plane brakes. The braking efficiency is balanced and efficient.
3.2.4 Break-line parking device, using advanced pulse break-line parking protection system, the system can stop and brake in time when any line disc on the equipment is broken or finished.
3.2.5 centralization loading, pneumatic thimble clamping is adopted.after bobbins compact. equipped with mechanical safety device.Improve production safety and efficiency. At the same time, an electronic limit protection is installed on the mechanical insurance device to control the main motor. The main motor can start only when all the insurance devices operate normally and enter the protection position.
3.2.6 The tension of the bobbins is controlled by pneumatic tension. The tension is controlled by PLC Automatic Coordinated tension controller. The tension is switched automatically and real-time according to the length signal to ensure that the tension of all bobbins are uniform from full to empty.
3.2.7 The front bracket of each main motor is equipped with operation buttons, such as spot moving, emergency stopping, lifting and descending of the upper tray, positioning, alarm bell and so on.
3.3 Side horizontal Mechanics electric automatic loading and unloading device
3.3.1 Concentrating the loading and unloading bobbins , adopting mechanics electric lifting trolley can complete the whole process of turning over, walking and mounting in turn. The operation is convenient and reliable, and the mounting efficiency is stable, fast and efficient.
3.3.2 adapt bobbins size PND 630
3.3.3 This machine side loading and unloading with small trolly.
3.4:Assembling and assembling die holder:
3.4.1 6 bobbins of main motor are individually assembling wire, and the 12/18/24 bobbins host motor an organic compacted.
3.4.2 The assembling die holder can be completed by cable drawing or compact laying up once.
3.5.Mechanical meter counter:
3.6 φ2000 double traction device:
3.6.1 ø2000 double traction device adapt double active, double support, double traction, great traction.
3.6.2 The two traction wheels adopt mutual natural separation, and the wheel groove is circular arc, so as to avoid the abrasion of the wire core during the traction process.
3.6.3 The traction shaft is welded by steel structure, and the whole traction mechanism has high strength and good synchronous performance.
3.7 φ2500 portal take up frame:
3.7.1 take up and traverse adopt end shaft type, electric lifting and clamping bobbins, with limit protection, and reliable performance.
3.7.2 The power of take up is driven by the 7.5kW motor through the three stage gear box.
