[0014] An adjustment unit is arranged on the rotating frame, and the adjustment unit is used to drive the adjustment seat to move horizontally.

[0015] Furthermore, a plurality of the adjustment seats are arranged in an array along the center line of the rotating frame.

[0017] Furthermore, a guide rod is horizontally penetrated through the first ear block, and one end of the guide rod away from the first ear block passes through the second ear block and slides freely horizontally.

[0018] Furthermore, a first spring is sleeved on the guide rod, and two ends of the first spring in the elastic force direction are respectively fixed to the electromagnet and the outer wall of the second ear block.

[0019] Furthermore, one end of the guide rod away from the electromagnet is sleeved with a limiting nut.

[0020] Furthermore, a lifting rod is vertically penetrated on the rotating frame, and the lifting rod slides freely on the rotating frame. A guide sleeve is obliquely fixed to the upper end of the lifting rod, and a core hole is coaxially opened on the guide sleeve. A loose detection unit is provided on the lifting rod.

[0021] Furthermore, the loose detection unit includes a limit ring sleeved on the lower end of the lifting rod, the limit ring is located below the rotating frame, a second spring is sleeved on the lifting rod, and two ends of the second spring in the elastic force direction elastically press against the rotating frame and the limit ring one by one, a pressure sensor is installed on the rotating frame, and a plastic ring is sleeved on the lifting rod, and the lower end surface of the plastic ring presses against the surface of the pressure sensor.

[0022] Furthermore, a cavity is provided inside the guide sleeve, and a communication opening which penetrates the interior of the cavity is provided on the outer wall of the guide sleeve.

[0023] A working method of a cable braiding device, applied to the cable braiding device as described above, the working method of the cable braiding device comprising:

[0024] The electromagnet is in a powered state and generates magnetism, thereby generating a magnetic attraction force on the second ear block, so that the second ear block drives the adjustment seat to move toward the electromagnet, and the first spring is compressed and accumulates elastic potential energy;

[0025] The cable core to be twisted is wound on the winding reel, and the end of the cable core unwound from the winding reel first passes through the core hole of the guide sleeve and then passes through the traction tube, and then the end passing through the traction tube is wound on the external winding device;

[0026] The rotating frame rotates, and the external winding device is started, and then the wire core is wound. During winding, the rotating frame rotates, so that the wire cores on multiple winding shafts are wound together to form a single wire core. In addition, during this process, the wire core is in a taut state, which can drive the guide sleeve to move upward. The limit ring will compress the second spring upward, and the second spring accumulates elastic potential energy. The plastic ring is out of contact with the surface of the pressure sensor, and no pressure signal is generated by the pressure sensor;

[0027] The external heat transfer oil delivery device delivers the high-temperature heat transfer oil into the cavity of the guide sleeve through the connecting port, and then the heat of the heat transfer oil is used to heat and soften the cable core;

[0028] When the wire core is being twisted, when the rotation speed of some of the winding shafts is greater than that of other winding shafts, the wire core on the winding shaft will become loose. When it is loose, the pulling force of the wire core on the guide sleeve is small, so that the elastic potential energy accumulated in the second spring is released, and the limit ring is driven to move downward, so that the lower end surface of the plastic ring is against the surface of the pressure sensor, so that the pressure sensor generates a pressure signal, and the pressure signal is then fed back to the external control module. The control module controls the electromagnet to cut off power, so that the elastic potential energy accumulated in the first spring is released, and the second ear block is driven to move in the direction away from the first ear block, so that the adjustment seat moves toward the outside of the rotating frame, so that the wire core on the winding shaft can be straightened, so that the guide sleeve is driven by the straightened wire core to move upward, so that the pressure sensor is out of contact with the plastic ring.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention can straighten the loose cable core by arranging an adjustment unit to drive the adjustment seat to move horizontally, thereby avoiding the loosening of the cable core caused by the excessive rotation speed of one of the winding shafts. In addition, the adjustment unit can automatically adjust the installation position of the adjustment seat on the rotating frame, so that when the cable core is loose, the cable core can be automatically straightened.

[0031] The present invention generates magnetism when the electromagnet is energized, and generates magnetic attraction to the second ear block, so that the second ear block drives the adjustment seat to move on the rotating frame. Conversely, when the electromagnet is powered off, the magnetism is lost, and the magnetic attraction to the second ear block disappears, and then the second ear block is driven by the first spring to move in a direction away from the rotating frame, so that when the adjustment seat moves on the rotating frame, the wire core can be automatically straightened;

[0032] The present invention provides a guide sleeve and a lifting rod. During the twisting process of the wire core, when the wire core is straightened, the wire core has an upward pulling force on the guide sleeve, so that the guide sleeve moves upward, and the plastic ring is separated from the contact state with the pressure sensor, so that the pressure sensor has no pressure signal. When the wire core is loose, the upward pulling force of the wire core on the guide sleeve is small, so the second spring will drive the limit ring to move downward, so that the plastic ring contacts the surface of the pressure sensor, so that the pressure sensor generates a pressure signal, which is then fed back to the external control module. The control module controls the electromagnet to cut off the power, so that the adjustment seat will move toward the outside of the rotating frame, thereby realizing automatic straightening of the wire core.

Through the setting of the limiting nut 17, the sliding rod stroke of the second ear block 14 on the guide rod 9 can be limited to prevent the second ear block 14 from being separated from the connection state with the guide rod 9.

[0043] A lifting rod 6 is vertically penetrated on the rotating frame 2, and the lifting rod 6 slides freely on the rotating frame 2. A guide sleeve 5 is fixedly connected to the upper end of the lifting rod 6 at an angle, and a core hole is coaxially opened on the guide sleeve 5.
