Abstract
Description
Technical Field
[0001] This utility model relates to annealing furnaces, and more particularly to a high-stability take-up machine in a wire drawing annealing furnace. Background Technology
[0002] In wire drawing annealing furnaces, a wire take-up machine is needed to draw the wire. Currently, the wire take-up machines on the market include... Figure 1 As shown, two take-up rollers are rotatably mounted on the frame. These rollers are connected to a geared motor via a synchronous belt mechanism. A guide wheel shaft is located on both sides of the frame, with several guide wheels spaced apart on it. During operation, the wire is wound from the guide wheel on the front guide wheel shaft onto the take-up roller, then onto the guide wheel on the rear guide wheel shaft, and finally enters the annealing furnace for annealing. Because the two ends of the take-up rollers are connected to the frame via seated bearings, assembly errors during assembly can cause misalignment between the two ends of the take-up roller. This can lead to vibration during high-speed rotation, causing the wire to become inconsistently tight and loose, affecting the traction effect and potentially even causing wire breakage.

The synchronous plate 164 ensures that the left end of the left section shaft 42 and the right end of the right section shaft 43 on the first guide wheel shaft 4 are fixedly connected to the left and right ends of the reinforcing rod 15, respectively, which improves the connection stability between the first guide wheel shaft 4 and the reinforcing rod 15. When it is necessary to adjust the position of the first guide wheel shaft 4 along the adjusting elongated hole 161, the locking nut 162 and the locking bolt 163 are loosened at the same time, and then the reinforcing rod 15 is pulled to adjust the first guide wheel shaft 4, thus facilitating the adjustment of the first guide wheel shaft 4.

Set bolts 422 are threaded into the set sleeves 421, and the set bolts 422 abut against the left shaft 42. By setting spacer sleeves 412 and set sleeves 421 to fix the first guide wheels 41 on the left shaft 42 at intervals, installation and positioning are greatly facilitated.
[0022] In use, the thread is wound from the first guide wheel 41 on the first guide wheel shaft 4 onto the corresponding take-up roller 3, and then from the take-up roller 3 onto the second guide wheel 51 on the second guide wheel shaft 5, which is aligned with the first guide wheel 41.
