Doubling machine for metallic threads

[0012] Such as figure 1 As shown, the wire doubling machine of the present invention includes a wire pay-off frame 1, an annealing furnace 6 and a wire take-up mechanism. The pay-off rack 1 is a frame structure, and the bottom of the pay-off rack 1 is provided with five reel shafts 22 (the specific number depends on the need). The five reel shafts are all arranged vertically, and their lower ends are welded to the bottom of the pay-off rack 1. On the crossbar, when working, a wire reel 23 wound with a wire 3 is placed on each reel 22. The top of the pay-off frame 1 is provided with five porcelain rings 2, and the five porcelain rings correspond to the disc shaft 22 underneath one by one, and they are all welded to the cross bar on the top of the pay-off frame 1.

[0013] The annealing furnace 6 has a box-shaped structure, and five spindles for placing the yarn spindles 21 are arranged below it, that is, along the two sides of the bottom. These spindles are arranged vertically and equally spaced, and their lower ends are welded to On the bottom plates on both sides of the annealing furnace 6, a yarn spindle 21 is placed on each spindle in the working state. Five tension controllers 7 are arranged on the top of the annealing furnace 6 along the two side walls. The tension controllers correspond to the spindle shafts below them one by one, and they are respectively fixed on both sides of the top plate of the annealing furnace 6.

[0014] The front and rear side walls of the annealing furnace 6 are respectively processed with five inlets 4 and outlets 10, these inlets and outlets are on the same horizontal line, and the inlet 4 on the front side wall and the rear side wall The outlets 10 on the top correspond one by one. A high temperature tube 5 is provided between the corresponding pair of wire inlet 4 and wire outlet 10, and both ends of the high temperature tube are inserted and fixed in the corresponding wire inlet 4 and wire outlet 10 respectively.

[0015] Such as figure 1 with figure 2 As shown, the wire take-up mechanism includes a bracket, which is composed of a rectangular parallelepiped base 20 and a rectangular parallelepiped frame 19. The cuboid base 20 and the cuboid frame 19 are frame structures and box-shaped structures, respectively. The cuboid frame 19 is installed on the cuboid base 20. The two side walls of the cuboid frame 19 are correspondingly processed with lower shaft holes, and a corresponding pair of lower A driven axle 16 is arranged between the shaft holes. The two ends of the driven wheel shaft 16 are respectively installed in the corresponding lower shaft holes through bearings and protruded out, and a take-up reel 17 is installed on the extending ends. On the two side walls of the rectangular parallelepiped frame 19 on the same side close to the take-up reel 17, that is, on the upper right side, upper shaft holes are correspondingly machined, and a driving axle 24 is arranged between the corresponding pair of upper shaft holes, and the middle of the driving axle 24 is A transmission wheel 25 is installed in a fixed shape, the two ends of which are respectively installed in the corresponding pair of upper shaft holes through bearings and protrude out, and a driving wheel 18 is installed on the extension end. The wheel surface of the driving pulley 18 is in contact with the disk surface of the take-up reel 17. A motor 26 is arranged in the cuboid base 20, the motor is fixed on the bottom plate of the cuboid base 20, and a transmission wheel 25 is fixed on the output shaft. A transmission belt is provided between the transmission wheel 25 on the output shaft of the motor 26 and the transmission wheel 25 on the driving axle 24. During operation, the motor 26 drives the driving wheel shaft 24 to rotate through the transmission wheel 25 and the transmission belt, and then the driving wheel shaft 24 and the driving wheels 18 at both ends thereof drive the take-up reel 17 to rotate. In addition, each driving axle 24 is fixed with a synchronous transmission wheel, and a pair of adjacent synchronous transmission wheels are equipped with a synchronous transmission belt. Through these synchronous transmission wheels and synchronous transmission belts, all the driving axles 24 can be rotated synchronously, thereby driving them. The transmission wheels 25 at both ends of the driven axle 16 rotate synchronously with the take-up reels 17 at both ends.

[0016] A support plate 15 is welded along each of the two longitudinal side walls of the rectangular parallelepiped frame 19. The upper parts of the two support plates are respectively bent outwards and then bent inwards so that their upper sections are parallel, and their upper edges are processed with Five small shaft holes, these small shaft holes correspond to the take-up reel 17 underneath one by one, each small shaft hole is fixed with a small shaft 13, and the extension end of each small shaft 13 is installed through a bearing There is a wire wheel 14.

[0017] A transition frame 11 is also provided between the annealing furnace 6 and the wire take-up mechanism. The transition frame is L-shaped, and the end of the horizontal section is fixed at the connection between the cuboid base 20 and the cuboid frame 19, and the upper end of the vertical section is The upper transition guide wheel 12 and the lower transition guide wheel 9 are respectively installed in the middle through the axle.

[0018] When working, the wire reel 23 and the yarn spindle 21 are respectively placed on the reel 22 of the pay-off stand 1 and the spindles on both sides of the annealing furnace 6, and the wires 3 on a wire reel 23 bypass the pay-off in turn A porcelain ring above the frame 1, a high temperature tube 5 passing through the annealing furnace 6, a lower transition guide wheel 9, an upper transition guide wheel 12 and a wire wheel 14 above the wire take-up mechanism, bypassing the middle and upper part of the transition frame 11 . At the same time, a yarn 8 on the annealing furnace 6 bypasses a tension controller 7 above it and merges with a metal wire 3 on the same wire wheel 14 of the wire take-up mechanism, and then is wound on a wire take-up On disk 17.
