Bin of the present invention has good effect for promoting usefulness of the present invention: during the dish line, the end of a thread with each tape inserts on the wire spool arc surface earlier, start drive motors then, the bin main shaft is driven to rotate, the clamping device that connects with the bin main shaft also rotates thereupon, by the also rotation synchronously of winding body that connecting rod is connected with the clamping device integral type, finish the dish line process.After finishing, the dish line enters winding process, before the coiling, earlier the locking nut at connecting rod two ends is backed out on the winding former, connecting rod is extracted out, make each wire spool become the individuality that can rotate separately relative to main shaft, then, identical with conventional way, the end of a thread traction of respectively organizing copper strips that dish is made also is fixed on the winding former, rotate winding former, bin outlet, copper strips floor-covering roll from level to level form the coil that needs on winding former.
Owing to separate by dividing plate between the wire spool on the bin, so phenomenon interlaced, that shoulder can not take place in the line process in going out when winding process.In addition, the copper strips of respectively organizing on the wire spool that dish makes exists the phenomenon that degree of tightness differs, if use conventional bin, copper strips that each group is coiled and cylindrical shell are unitary rotation, and the copper cash that cylindrical shell is drawn the most tightly drives rotation, so other loose copper strips can only be in a lax state always, so just wander off easily, get lines crossed.And this device each wire spool when outlet all is the individuality that can rotate separately relative to main shaft, copper strips for coiling compactness on the wire spool, wire spool can be followed the rotation line sending of winding former when outlet, for the lax copper strips of coiling on the wire spool, lax that part of copper strips can follow the rotation of winding former to cover earlier, be tightened up up to copper strips, wire spool just begins to rotate.Like this, go out each wire spool of line process and work alone, in good order, the effect that degree of tightness is adjusted automatically, initiatively rectified a deviation in the time of playing outlet.
Therefore, bin of the present invention can reduce interlaced, the phenomenon shouldered of when coiling tape, and degree of tightness is adjusted automatically, can initiatively be rectified a deviation during coiling, can significantly reduce the time of shutting down the reason line, raises the efficiency.
Owing to separate by dividing plate between the wire spool on the bin, thus tape and have the gap each other when drawing, and between winding former place tape, need mutually near to simulate whole paper tinsel, therefore, in fact tape presents the trapezoidal shape convergence on the whole from back to front.The existence at this convergence oblique angle is unfavorable for drawing in metal strap.If sufficient fore-and-aft distance is arranged, make bin and winding former that extremely long distance be arranged, can reduce convergency to reasonable range, wind the line successfully with assurance.But, often there is limitation the installation site of machine in the reality, therefore need install position-limit mechanism additional in the metal strap course of conveying, to shrink the spacing between the tape on one's own initiative, make the convergence oblique angle of tape when arriving winding former sufficiently little, make between the tape mutually near and simulate whole paper tinsel.
Because the performance of transformer coil and coil surface are long-pending relation is arranged, because lateral area increases, piecing together the paper tinsel plate of system has bigger surface area than whole paper tinsel plate, and therefore, the performance of the coil that its coiling forms is better than the coil of whole paper tinsel plate coiling.
Beneficial effect of the present invention is: (1) can adapt to different coil specifications by the radical of adjusting tape, avoided puzzlement for the coil manufacturing metal forming separately of different in width, also reduced the time of waiting metal forming simultaneously, shorten the delivery cycle of coil, alleviated the pressure that working capital of enterprises is taken in a large number; (2) the tape processing charges have greatly reduced processing cost well below paper tinsel.
