[0018] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0019] like Figures 1 to 3 As shown, the utility model provides a swing arm tension shaft discharge belt machine, which includes a machine platform 1, a reciprocating driving mechanism 2 installed on the machine platform 1, a moving seat 3 installed on the moving end of the reciprocating driving mechanism 2, a belt reel 4 rotatably connected to the moving seat 3, a rotating driving mechanism 5 installed on the moving seat 3 and used to drive the belt reel 4 to rotate, a swing arm 6 rotatably connected to the moving seat 3, a tension roller 7 rotatably connected to the swing arm 6, a detection block 8 installed on the swing arm 6, a distance sensor 9 installed on the moving seat 3 and corresponding to the detection block 8, and a rotating driving mechanism 5 installed on the moving seat 3 and used to drive the belt reel 4 to rotate. The broken belt sensor 10 of the seat 3, the bracket 11 installed on the machine 1, a plurality of guide rollers 12 rotatably connected to the bracket 11, and a correction detection mechanism 13 installed on the bracket 11 and located between two adjacent guide rollers 12, the correction detection mechanism 13 is electrically connected to the reciprocating drive mechanism 2, the detection block 8 is provided with a variable distance detection surface 14, the variable distance detection surface 14 is used to trigger the distance sensor 9, the distance sensor 9 is electrically connected to the rotating drive mechanism 5, the swing arm 6 is used to trigger the broken belt sensor 10, and the broken belt sensor 10 is located below the distance sensor 9.

[0020] In practical applications, the tape roll is mounted on the tape reel 4, the tape of the tape roll is wound around the tension roller 7 and a plurality of guide rollers 12 in sequence, and passes through the deviation correction detection mechanism 13, the rotation drive mechanism 5 drives the tape reel 4 to rotate to unwind the tape, and in the process of unwinding the tape, the swing arm 6 can drive the tension roller 7 and the detection block 8 to swing, the tension roller 7 applies a certain tension to the tape, the distance sensor 9 performs distance detection on the variable distance detection surface 14 of the detection block 8, and feeds back the distance detection result to the rotation drive mechanism 5, so that the rotation drive mechanism 5 can control the rotation according to the distance detection result. The unwinding speed of the tape roll on the tape reel 4 is controlled to ensure that the tension of the tape is constant. The reciprocating drive mechanism 2 drives the movable seat 3 to reciprocate with the tape reel 4 so that the tape roll can be unwinded in an axial manner. The deviation correction detection mechanism 13 performs deviation correction detection on the position of the tape and feeds back the deviation correction detection result to the reciprocating drive mechanism 2, so that the reciprocating drive mechanism 2 can compensate for the displacement of the tape roll to correct the output position of the tape, ensure that the tape is always in a constant unwinding position, and ensure the position accuracy and stability of the tape output. In addition, when the tape roll is used up or the tape roll is broken, the swing arm 6 will swing downward freely and trigger the broken tape sensor 10. The broken tape sensor 10 will feed back a signal to the external alarm, causing the alarm to sound an alarm to remind the operator to replace or maintain the tape roll. The utility model can realize the axis-arranged tape unwinding and at the same time realize the deviation correction of the tape unwinding position, the tape unwinding speed control, the tension adjustment and the tape breakage monitoring. The distance sensor 9 and the detection block 8 are non-contact detection, have a long service life and are not easy to be damaged.

[0021] Specifically, the rotation drive mechanism 5 can adopt a motor, and the reciprocating drive mechanism 2 can adopt a screw module, which will not be described in detail here.

[0022] In this embodiment, the bracket 11 is equipped with a tension sensor 15, one of the guide rollers 12 is connected to the input end of the tension sensor 15, and the tension sensor 15 is electrically connected to the rotation drive mechanism 5. When the material tape moves around the guide roller 12, the tension sensor 15 can detect the tension of the material tape around the guide roller 12, so as to detect the tension of the unwinding tape in real time and feed back the tension detection result to the rotation drive mechanism 5.

[0023] In this embodiment, the variable distance detection surface 14 is an inclined surface or a concave arc surface.

[0024] In this embodiment, a counterweight 16 is detachably connected to the tension roller 7 or the swing arm 6, and the counterweight 16 is rotatably connected to the tension roller 7 or the swing arm 6. The counterweight 16 can provide appropriate tension to the material strip, and according to the different tensions required by different material strips, the tension can be adjusted by replacing the weight of the counterweight 16 to meet the requirements of different tensions.

Under normal circumstances, the material tape moves in the normal tape passing space 19, and when the material tape deviates, the material tape triggers one of the photoelectric sensors 18, and the photoelectric sensor 18 feeds back a signal to the reciprocating drive mechanism 2, so that the reciprocating drive mechanism 2 performs displacement compensation on the tape roll until the material tape of the tape roll is located in the normal tape passing space 19.

[0026] Of course, the deviation correction detection mechanism 13 may also adopt an existing deviation correction detection device, which will not be described in detail here.

[0027] In this embodiment, the mounting plate 17 is provided with a spacing adjustment slot 20, which is used to adjust the position of the photoelectric sensor 18 on the mounting plate 17. This structural design makes the distance between the two photoelectric sensors 18 adjustable, that is, the width of the normal tape passing space 19 is adjustable to meet the use of tapes of different widths.

[0028] In this embodiment, the bracket 11 is rotatably connected to a core wire guide wheel 21, and the core wire guide wheel 21 is used to guide and transport the external core wire.

[0029] All technical features in this embodiment can be freely combined according to actual needs.
