DETAILED DESCRIPTION

[0023] Embodiment 1

[0024] like Figure 1-Figure 2 As shown, a horizontal double-layer wrapping machine proposed in this embodiment includes a chassis 1, a turntable 8, a cable unwinding roller 4, a rotation detection mechanism and two sets of unwinding mechanisms.

[0025] One side of the chassis 1 is open and has a chassis door 2 rotatably mounted thereon; the chassis 1 has a through hole a101 .

[0027] The two sets of unwinding mechanisms are both installed on the turntable 8, and the two sets of unwinding mechanisms are respectively installed on both sides of the turntable 8. The unwinding mechanism includes an unwinding roller 14, which is rotatably installed on the turntable 8; the cable unwinding roller 4 is rotatably installed inside the chassis 1.

[0028] The rotation detection mechanism includes a circular tube 5 and a color sensor 6. The circular tube 5 is coaxially arranged with the turntable 8 and is fixedly connected with the turntable 8. The color sensor 6 is installed on the circular tube 5. An LED light can be installed inside the chassis to provide good lighting conditions for the interior of the chassis, thereby facilitating the recognition work of the color sensor.

[0029] In the present technical solution, the cable is wound up by a traction mechanism, and at the same time, the power assembly works to drive the turntable 8 to rotate, thereby driving the two unwinding rollers 14 to rotate around the center of the turntable 8, so that the film on the unwinding roller 14 is wound around the cable surface, and the turntable 8 drives the round tube 5 to rotate during the rotation, and the rotation of the round tube 5 drives the color sensor 6 to rotate around the outer circumference of the cable. When the color sensor 6 detects that the film is not wrapped around the cable surface (the color of the film is inconsistent with the color of the cable surface, and when part of the cable is exposed, the exposed position is recognized by the color sensor 6), the color sensor 6 feeds back the signal to the controller 12, and the controller 12 then automatically alarms through the alarm installed inside it.

[0030] Embodiment 2

[0033] Embodiment 3

[0034] like Figure 4 As shown, a horizontal double-layer wrapping machine proposed in this embodiment is compared with the first embodiment. In this embodiment, a counter 24 is installed on the rotating shaft of the lower pressure wheel 191, which drives the lower pressure wheel 191 to rotate during the movement of the cable. The counter 24 can detect the number of rotations of the lower pressure wheel 191 and feed the data back to the controller 12, thereby realizing the detection of the cable pull-out length and the cable movement speed. When the cable movement speed changes, the controller 12 automatically adjusts the traction speed of the traction mechanism to keep the cable movement speed constant, so as to improve the processing quality of the cable.
