[0032] Working principle:
[0033] When in use, the metal wire of the heating wire is first passed around the feed guide roller group 3, and then guided by the feed guide roller group 3 to enter between the upper roller 5 and the lower roller 6 of the flattening mechanism, and then the upper roller 5 and the lower roller 6 cooperate to flatten the metal wire, and then it is wound around the fixed guide roller 14 and the movable guide roller 17 of the tensioning mechanism, so that the gravity of the slider 16 itself can give the movable guide roller 17 a downward force along the axial vertical direction of the slide rail 15, thereby effectively ensuring the tension of the metal wire. In this embodiment, four winding grooves can be set on the fixed guide roller 14, and three winding grooves can be set on the movable guide roller 17, so that the metal wire is sequentially wound around the first winding groove of the fixed guide roller 14, the first winding groove of the movable guide roller 17, the second winding groove of the fixed guide roller 14, the second winding groove of the movable guide roller 17, the third winding groove of the fixed guide roller 14, the third winding groove of the movable guide roller 17, and the fourth winding groove of the fixed guide roller 14 and then led out. By winding three times between the fixed guide roller 14 and the movable guide roller 17, the tension and stability of the metal wire are effectively guaranteed.
[0034] Afterwards, the metal wire led out from the fourth winding groove of the fixed guide roller 14 is wound onto the wire-taking drum 18 of the wire-taking mechanism, and the driving shaft 19 is driven by the driving motor to rotate, thereby driving the wire-taking drum 18 to rotate to carry out the wire-taking work.
[0035] In the present invention, firstly, a tensioning mechanism is provided, so that when the take-up drum 18 rotates to take up the wire too fast or too slow, the gravity of the slider 16 can be used to keep the metal wire always under a certain tension. In this embodiment, proximity switches can be provided above and below the support column 13, and the sensing ends of the two proximity switches correspond to the slider 16, and the signal output end of the proximity switch is connected to the controller, so that when the slider 16 moves to the top or bottom, the proximity switch can sense and transmit the signal to the controller, and then the controller controls the speed of the driving motor to adjust adaptively, and then adjusts the take-up speed of the take-up drum 18, thereby effectively avoiding the problem of the metal wire breaking or loosening and winding.
[0036] In addition, by installing a mounting frame 10 above the support frame 4 and installing a screw driving mechanism in the mounting frame 10, the screw driving mechanism can be used to drive the screw 11 to rotate, and then the lower end of the screw 11 can be threadedly connected to the first bearing seat 9 to drive the first bearing seat 9 to perform fine adjustment in the up and down directions, thereby achieving fine adjustment of the position of the upper roller 5, and fine adjustment of the pressing gap between the upper roller 5 and the lower roller 6, so as to adapt to the flattening work of metal wires of different specifications and sizes.
