[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model.
[0020] Example 1, as Figures 1-4 shown, a tensioning device for a heating wire metal wire includes a support column 1. A slide rail 2 is vertically installed on the front surface of the support column 1. A slide block 3 is slidably connected to the outer surface of the slide rail 2. A mounting plate 4 is installed on the outer surface of the slide block 3. A moving guide roller 5 is installed on the outer surface of the mounting plate 4 through a mounting shaft; A support frame 6 is fixedly installed at the upper end of the support column 1. A fixed guide roller 7 is installed on the front side of the support frame 6 through a mounting shaft. The middle of the support frame 6 is respectively rotatably connected to a first rotating shaft 8 and a second rotating shaft 9 through bearings. A first gear 10 and a second gear 11 are fixedly installed at one ends of the first rotating shaft 8 and the second rotating shaft 9 respectively. A chain 12 is wound around the surfaces of the first gear 10 and the second gear 11. One end of the chain 12 is connected to the slide block 3, and the other end of the chain 12 is fixedly connected to a counterweight 13.
[0021] In this embodiment, a first fixed roller groove 71, a second fixed roller groove 72, a third fixed roller groove 73 and a fourth fixed roller groove 74 are sequentially arranged on the outer circumferential surface of the fixed guide roller 7 from inside to outside. A first moving roller groove 51, a second moving roller groove 52 and a third moving roller groove 53 are sequentially arranged on the outer circumferential surface of the moving guide roller 5 from inside to outside; The heating wire metal wire is led out after sequentially passing around the first fixed roller groove 71, the first moving roller groove 51, the second fixed roller groove 72, the second moving roller groove 52, the third fixed roller groove 73, the third moving roller groove 53 and the fourth fixed roller groove 74.
[0022] Working principle:
[0023] In use, the heating wire metal wire produced by the previous process is introduced into the first fixed roller groove 71 on the outer circumferential surface of the fixed guide roller 7, and then bypasses the first fixed roller groove 71, the first moving roller groove 51, the second fixed roller groove 72, the second moving roller groove 52, the third fixed roller groove 73, the third moving roller groove 53 and the fourth fixed roller groove 74 respectively, and is led out through the fourth fixed roller groove 74 and introduced into the subsequent wire collecting mechanism. In this embodiment, under the action of the gravity of the moving guide roller 5 and the slider 3, the whole moving guide roller 5 always has a downward acting force, so that through the downward pulling force of the moving guide roller 5, through the action of the moving guide roller 5 and the fixed guide roller 7, a pulling action can be applied to the metal wire wound on the fixed guide roller 7 and the moving guide roller 5, so as to effectively ensure the tension of the metal wire itself. In addition, in this embodiment, by setting the counterweight 13, one end of the chain 12 is connected to the slider 3, and the other end of the chain 12 is connected to the counterweight 13, so that through the lever principle, the counterweight 13 can be used to offset part of the gravity of the slider 3 and the moving guide roller 5. Therefore, according to the requirements of heating wire metal wires of different specifications, different weights of counterweights 13 can be replaced, so as to quickly adjust the tension of the metal wire according to the requirements of heating wire metal wires of different specifications, so as to ensure that the metal wire can have a tension suitable for its own specifications. Then the utility model can meet the tension requirements of heating wire metal wires of various specifications.
[0024] Embodiment 2, as a further preferred scheme of Embodiment 1, a driving gear 14 is fixedly installed at the other end of the first rotating shaft 8, an angle potentiometer 15 is fixedly installed on the left side surface of the support frame 6 through a mounting support plate 21, a driven gear 16 is fixedly installed on the rotating terminal of the angle potentiometer 15, and the driving gear 14 meshes with the driven gear 16.
[0025] Therefore, when the current wire pay-off speed is different from the subsequent wire take-up speed, at this time, the slider 3 moves up and down along the slide rail 2 to ensure the tension of the wire between the fixed guide roller 7 and the movable guide roller 5; and when the slider 3 moves up and down, it will also drive the chain 12 to move accordingly, and then drive the first gear 10 to rotate. Thus, the driving tooth 14 is driven to rotate synchronously through the first rotating shaft 8 in the middle of the first gear 10. Also, since the driving tooth 14 meshes with the driven gear 16 on the rotating terminal of the angle potentiometer 15, therefore, the rotation state of the first gear 10 can be monitored in real time through the angle potentiometer 15. Thus, by measuring the rotation state of the first gear 10, the sliding position and sliding speed of the slider 3 can be accurately judged. In this embodiment, the signal output end of the angle potentiometer 15 can be connected to the signal input end of the controller, and the signal output end of the controller can be connected to the driving motor of the wire take-up mechanism. Thus, according to the sliding position and sliding speed of the slider 3 output by the angle potentiometer 15, the rotation speed of the driving motor of the wire take-up mechanism can be adjusted adaptively, and then the wire take-up rate can be adjusted, so as to effectively avoid the slider 3 sliding to the uppermost or lowermost position of the slide rail 2, and further avoid the problems of wire breakage or slack.
[0026] Embodiment 3, as a further preferred solution of Embodiment 1, photoelectric sensors 17 are provided at both the upper end and the lower end of the side surface of the support column 1, and an induction sheet 18 is fixedly installed on the side surface of the mounting plate 4. The induction sheet 18 matches the induction end of the photoelectric sensor 17, and the signal output end of the photoelectric sensor 17 is connected to the signal input end of the controller. Therefore, when the slider 3 slides to the uppermost or lowermost position of the slide rail 2, it will be sensed by the photoelectric sensor 17 and the induction sheet 18 on the side surface of the mounting plate 4. Thus, the signal can be transmitted to the controller through the photoelectric sensor 17, and the controller controls the alarm to send an alarm to the staff, so as to timely adjust the wire pay-off or wire take-up speed of the wire, and avoid the problems of wire breakage or slack.
[0027] Embodiment 4, as a further preferred solution of Embodiment 1, buffer cylinders 19 are fixedly installed at both the upper end and the lower end of the support column 1, and a limit block 20 is fixedly installed on the inner side surface of the mounting plate 4. The upper surface and the lower surface of the limit block 20 are respectively in contact with the buffer columns of the two buffer cylinders 19 in a matching manner. The buffer cylinders 19 can limit the slider, so that when the slider 3 slides to the uppermost or lowermost position of the slide rail 2, effective buffering can be achieved through the buffer columns of the buffer cylinders 19.
[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
