[0019] To make the purpose, technical solution 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 drawings in the present utility model.
[0020] Example 1, as Figure 1-2 shown, a take-up speed control device for an electric heating wire core wire includes a machine body 1, a support frame 2 is installed above the machine body 1, an inlet guide roller 3 is rotatably connected to the front side surface of the support frame 2, an inlet driving roller 4 is rotatably connected to the upper part of the front side surface of the machine body 1, an inlet driving motor is installed inside the machine body 1, and the driving end of the inlet driving motor is in transmission connection with the inlet driving roller 4;
[0021] On the left and right sides below the inlet driving roller 4, a take-up component and a speed control component are respectively arranged. The take-up component includes a take-up guide roller 5 and a support rod 6. The support rod 6 is fixedly installed on the front side surface of the machine body 1 through a screw, and the take-up guide roller 5 is rotatably connected to the front side surface of the support rod 6; the speed control component includes a rotating column sleeve 7 and a microswitch 8. The rotating column sleeve 7 is fixedly installed on the front side surface of the machine body 1. Arc-shaped notches 20 are symmetrically arranged on both the left and right side surfaces of the rotating column sleeve 7. A rotating column 9 is rotatably connected inside the rotating column sleeve 7. One end of a long rod 10 is connected to the side surface of the rotating column 9. The other end of the long rod 10 passes through the arc-shaped notch 20 and is rotatably connected to a guide roller 11 through a rotating shaft. A counterweight 12 and a pressing rod 13 are fixedly installed on the long rod 10; the microswitch 8 is fixedly installed on the front side surface of the machine body 1. The microswitch 8 is located below the long rod 10, and the pressing rod 13 is in movable contact with the moving contact piece of the microswitch 8;
[0022] A take-up driving roller 14 is installed below the front side surface of the machine body 1. A take-up driving motor is installed inside the machine body 1. The driving end of the take-up driving motor is in transmission connection with the take-up driving roller 14; the signal output end of the microswitch 8 is connected to the signal input end of the controller, and the signal output end of the controller is respectively connected to the inlet driving motor and the take-up driving motor.
[0023] Working principle:
[0024] During use, as shown in the figure, the core wire of the heating wire bypasses the incoming wire guide roller 3 and then is wound around the outer surface of the incoming wire driving roller 4. After that, it bypasses the guide roller 11 and the take-up wire guide roller 5 in sequence, and then is wound around the take-up drum on the outer surface of the take-up driving roller 14 for taking up the wire.
[0025] When the take-up drum on the take-up driving roller 14 is full of the core wire of the heating wire, the staff can directly lift the guide roller 11 upward, so that the entire long rod 10 rotates upward around the central axis of the rotating column 9, and then the pressing rod 13 on the long rod 10 is separated from the moving contact piece of the micro switch 8. Thus, the incoming wire driving motor and the take-up driving motor can be controlled by the controller to stop operating, so that the incoming wire driving roller 4 and the take-up driving roller 14 stop the wire taking-up action; thus effectively avoiding the continuous output and winding of the core wire of the heating wire, and significantly reducing the problem of waste of the core wire. At this time, the take-up drum on the incoming wire driving roller 4 can be directly taken out and replaced. And because the guide roller 11 is lifted upward at this time, the guide roller 11 is closer to the position between the incoming wire driving roller 4 and the take-up wire guide roller 5, so that the tension of the core wire of the heating wire itself can be effectively reduced, and then the problem that the core wire of the heating wire is broken due to excessive tension during the replacement of the take-up drum can be effectively avoided.
[0026] After the replacement is completed, the long rod 10 is directly released. At this time, due to the gravity of the counterweight 12, the long rod 10 rotates downward around the central axis of the rotating column 9 again, and through the limiting action of the arc-shaped notch 20 opened on the side surface of the rotating column sleeve 7, the rotation angle of the long rod 10 is limited. When the long rod 10 rotates to the lowest position, the pressing rod 13 presses on the moving contact piece of the micro switch 8, so that the moving contact piece of the micro switch 8 is closed, and then the incoming wire driving motor and the take-up driving motor can be controlled by the controller to start, and then the wire taking-up work of the core wire of the heating wire can be continued. The whole process only needs to manually lift and lower the guide roller 11, without complex operation steps, thus effectively reducing the operation difficulty and labor intensity. The replacement process of the take-up drum is simplified, the downtime is reduced, and the production efficiency and equipment utilization rate are improved.
[0027] Embodiment 2, as a further preferred solution of Embodiment 1, two groups of incoming wire guide rollers 3 are provided. Installation shafts are respectively installed above and below the front side surface of the support frame 2, and the two groups of incoming wire guide rollers 3 are respectively rotatably connected to the outer surfaces of the two installation shafts. By providing two groups of incoming wire guide rollers 3, the core wire of the heating wire bypasses the two incoming wire guide rollers 3 in sequence, thus ensuring both the orderliness of the core wire of the heating wire and the tension of the core wire of the heating wire during wire taking-up.
[0028] Embodiment 3, as a further preferred solution of Embodiment 1, two sets of wire-receiving guide rollers 5 are provided. Installation shafts are respectively installed above and below the front side of the support rod 6. The two sets of wire-receiving guide rollers 5 are respectively rotatably connected to the outer surfaces of the two installation shafts. By providing two sets of wire-receiving guide rollers 5, the heating wire core wire sequentially bypasses the two wire-receiving guide rollers 5, thus ensuring the tension of the heating wire core wire during wire receiving.
[0029] Embodiment 4, as a further preferred solution of Embodiment 1, strip-shaped slot holes 15 are provided on the surface of the long rod 10. Threaded through holes are provided on the surfaces of the counterweight 12 and the pressure rod 13. A first locking bolt 16 and a second locking bolt 17 are provided in the strip-shaped slot holes 15. The stud end of the first locking bolt 16 passes through the strip-shaped slot hole 15 and is connected to the threaded through hole on the surface of the counterweight 12. The stud end of the second locking bolt 17 passes through the strip-shaped slot hole 15 and is connected to the threaded through hole on the surface of the pressure rod 13.
[0030] Therefore, when installing the counterweight 12 and the pressure rod 13, the counterweight 12 and the pressure rod 13 can be directly placed at the rear position of the long rod 10. Then, the stud ends of the first locking bolt 16 and the second locking bolt 17 are respectively passed through the strip-shaped slot hole 15 from the front side of the long rod 10 and then connected to the threaded through holes on the surfaces of the counterweight 12 and the pressure rod 13 respectively. After that, by moving the stud ends of the first locking bolt 16 and the second locking bolt 17 along the axial direction of the strip-shaped slot hole 15, the positions of the counterweight 12 and the pressure rod 13 are adjusted so that the pressure rod 13 can cooperate with the moving contact piece of the microswitch 8. Then, the first locking bolt 16 and the second locking bolt 17 are tightened to lock and fix the counterweight 12 and the pressure rod 13.
[0031] Embodiment 5, as a further preferred solution of Embodiment 1, a hook 18 is provided above the long rod 10. The upper end of the hook 18 is installed on the front side of the machine body 1 through a mounting bolt. The lower end of the hook 18 is movably hung on the long rod 10. Therefore, after the long rod 10 is lifted to a proper position, in this embodiment, the lifting angle of the long rod 10 can be limited through the arc-shaped notch 20, so that the maximum height of the long rod 10 lifted is the proper position. At this time, the hook 18 can just be hung on the long rod 10 to suspend and fix the long rod 10. Thus, it is convenient for the staff to take out and replace the wire-receiving drum. In this embodiment, the hook 18 can be hung in cooperation with the strip-shaped slot hole 15, or a hanging hole can be provided on the upper surface of the long rod 10 so that the hanging hole cooperates with the hook 18. This is not limited here, as long as it is ensured that the hook 18 can suspend and fix the long rod 10. And after the replacement is completed, the hook 18 can be separated from the long rod 10.
[0032] Embodiment Six, as a further preferred solution of Embodiment One, a limiting block 19 is provided at one end of the rotating column 9 away from the long rod 10, and the limiting block 19 moves between the arc-shaped notches 20. The rotation angle of the long rod 10 is further limited by the limiting block 19 to prevent the long rod 10 from rotating excessively and damaging the microswitch 8.
[0033] 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 described 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.
