[0053] like Figure 1-13 As shown, the present invention provides a processing device for a high-strength, crack-resistant, and flame-retardant aluminum alloy cable 700, comprising a frame 100, on which a turntable 200, a winding assembly for winding the cable 700, and a driving assembly for driving the turntable 200 to rotate are provided. A discharge assembly is provided on the turntable 200. The discharge assembly includes a plurality of discharge units evenly arranged around the rotation centerline of the turntable 200, and the discharge unit includes a discharge roller 541, which is rotatably connected to the turntable 200. Preferably, the power input shaft of the discharge roller 541 is transmission-connected to the power output shaft of the second motor 542. Preferably, the second motor 542 is a damping motor.

[0054] The winding assembly includes a winding roller 410 and a winding motor 420, and the winding roller 410 is rotatably connected to the frame 100. The winding motor 420 is fixedly mounted on the frame 100, and the power output shaft of the winding motor 420 is drivingly connected to the power input shaft of the winding roller 410.

[0055] The driving assembly includes a first motor 300 , which is fixedly mounted on the frame 100 . The power output shaft of the first motor 300 is in driving connection with the power input shaft of the turntable 200 to drive the turntable 200 to rotate.

[0056] During operation, the unwinding assembly releases the cable 600 wound on the unwinding roller 541, and at the same time, the driving assembly drives the turntable 200 to rotate, so that multiple cables 600 are wound. During this process, the winding assembly synchronously winds up the finished cable 700. These are all prior art and will not be described in detail here.

[0057] The unloading assembly also includes a clamping mechanism and a driving mechanism.

[0058] The clamping mechanism is disposed on the turntable 200 and is capable of reciprocating between a clamping position and a release position along the radial direction of the turntable 200, i.e., the clamping mechanism is slidably connected to the turntable 200. When the clamping mechanism is in the release position, the distance between the clamping mechanism and the rotation centerline of the turntable 200 is relatively close.

[0059] The clamping mechanism has a clamping state capable of clamping the cable 600 and a releasing state capable of releasing the cable 600. When the clamping mechanism moves from the clamping position to the releasing position, the clamping mechanism is in the clamping state; when the clamping mechanism moves from the releasing position to the clamping position, the clamping mechanism is in the releasing state.

[0060] There are two clamping mechanisms, which are arranged in sequence and spaced apart along the radial direction of the turntable 200 , and when one of the clamping mechanisms is in the clamping position, the other clamping mechanism is in the releasing position.

[0061] The driving mechanism is provided on the turntable 200 and is used to drive the two clamping mechanisms to move synchronously. When one of the clamping mechanisms moves from the clamping position to the releasing position, the other clamping mechanism moves from the releasing position to the clamping position.

[0062] In order to clearly and understandably illustrate the working principle of the present invention, the two clamping mechanisms are respectively named as clamping mechanism A and clamping mechanism B.

[0063] During operation, in the initial state, one of the clamping mechanisms is in the clamping position and remains in the clamping state, while the other clamping mechanism is in the release position and remains in the release state. Here, we assume that clamping mechanism A is in the clamping position and clamping mechanism B is in the release position.

[0064] The drive mechanism drives clamping mechanism A to move from the clamping position to the release position, and at the same time, synchronously drives clamping mechanism B to move from the release position to the clamping position. When clamping mechanism A moves to the release position, clamping mechanism A switches from the clamping state to the release state. At the same time, clamping mechanism B moves to the clamping position and clamping mechanism B switches from the release state to the clamping state.

[0065] Afterwards, the drive mechanism drives clamping mechanism B to move from the clamping position to the release position, and at the same time, it synchronously drives clamping mechanism A to move from the release position to the clamping position. When clamping mechanism B moves to the release position, clamping mechanism B switches from the clamping state to the release state. At the same time, clamping mechanism A moves to the clamping position and switches from the release state to the clamping state.

[0066] During the process of releasing the cable 600 from the unwinding roller 541, the driving mechanism alternately moves the clamping mechanism A and the clamping mechanism B from the clamping position to the releasing position or from the releasing position to the clamping position, thereby achieving the purpose of continuously releasing the cable 600. During the process of releasing the cable 600, one of the clamping mechanisms is always in the clamping state, thereby keeping the cable 600 in a taut state. Therefore, even when the cable 600 on the unwinding roller 541 is about to be released, the cable 600 can still be kept in a taut state.

[0067] like Figure 1-13 As shown, in this embodiment, the clamping mechanism includes a first clamping block 511, a second clamping block 512 and a driving structure.

[0068] The first clamping block 511 is slidably connected to the turntable 200 so that the first clamping block 511 can move radially along the turntable 200. Specifically, a sliding seat 516 is provided on the turntable 200. The sliding seat 516 is slidably connected to the turntable 200 so that the sliding seat 516 can move radially along the turntable 200. The first clamping block 511 is fixedly connected to the sliding seat 516.

[0069] The second clamping block 512 is disposed on a side of the first clamping block 511 facing the turntable 200. The second clamping block 512 is slidably connected to the first clamping block 511, so that the second clamping block 512 can not only reciprocate between a clamping position and a release position in a direction toward or away from the first clamping block 511, but can also move along with the first clamping block 511 in the radial direction of the turntable 200. Specifically, a guide rod 517 is disposed between the sliding seat 516 and the first clamping block 511. The two ends of the guide rod 517 are fixedly connected to the sliding seat 516 and the first clamping block 511, respectively. The second clamping block 512 is slidably connected to the guide rod 517.

[0070] The driving structure is arranged on the first clamping block 511, and the driving structure is used to drive the second clamping block 512 to move back and forth between the clamping position and the release position. Specifically, when clamping, the driving structure drives the second clamping block 512 from the release position to the clamping position, and when releasing, the driving structure drives the second clamping block 512 to move from the clamping position to the release position.

[0071] During clamping, the drive structure drives the second clamping block 512 toward the first clamping block 511, reducing the distance between the first clamping block 511 and the second clamping block 512, thereby clamping the cable 600. During release, the drive structure drives the second clamping block 512 away from the first clamping block 511, increasing the distance between the second clamping block 512 and the first clamping block 511, thereby releasing the cable 600. This arrangement features a simple structure, a reasonable design, and convenient operation.

[0072] like Figure 1-13 As shown, in this embodiment, the driving structure includes a permanent magnet 513 , an electromagnet 514 and an elastic element 515 .

[0073] The permanent magnet 513 is fixedly embedded in the side wall of the second clamping block 512 on the side away from the first clamping block 511. The electromagnet 514 is embedded in the side of the turntable 200 facing the second clamping block 512 and is fixedly connected to the first clamping block 511. Specifically, the electromagnet 514 is fixedly embedded in the side wall of the sliding seat 516 on the side facing the second clamping block 512. The magnetism of the electromagnet 514 and the permanent magnet 513 on the opposite side is the same. The two ends of the elastic element 515 are respectively connected to the first clamping block 511 and the second clamping block 512, and in the natural state, the elastic element 515 applies an elastic force to the second clamping block 512 so that the second clamping block 512 has a tendency to move from the clamping position to the release position. Specifically, in this embodiment, the elastic element 515 is a spring.

[0074] When clamping, the electromagnet 514 is energized. Since the magnetism of the electromagnet 514 and the permanent magnet 513 on opposite sides is the same, when the electromagnet 514 is energized, a magnetic repulsion force is generated between the electromagnet 514 and the permanent magnet 513. Under the action of this magnetic repulsion force, the second clamping block 512 is driven from the release position to the clamping position, thereby achieving the purpose of clamping the cable 600.

[0075] When releasing, the electromagnet 514 is powered off, and under the action of the elastic force of the elastic element 515 , the second clamping block 512 is driven from the clamping position to the releasing position, thereby releasing the cable 600 .

[0076] like Figure 1-13 As shown, in this embodiment, the driving mechanism includes a lead screw 521, a nut 522 and a damping structure.

[0077] The lead screw 521 is rotationally connected to the turntable 200. The nut 522 is slidably connected to the turntable 200, enabling radial movement of the nut 522 along the turntable 200. The nut 522 is sleeved onto the lead screw 521. Two nuts 522 are provided, each fixedly connected to the two clamping mechanisms. Specifically, the two nuts 522 are fixedly connected to corresponding sliding seats 516. Rotating the lead screw 521 drives the two nuts 522 toward or away from each other, thereby driving one of the two clamping mechanisms from a clamped position to a released position and the other from a released position to a clamped position simultaneously. Specifically, the circumferential wall of the lead screw 521 is provided with two externally threaded sections with the same pitch but opposite helical directions. The lead screw 521 is transmission-connected to the two nuts 522 via these two externally threaded sections, so that when the lead screw 521 rotates, it simultaneously drives the two nuts 522 to move, and the two nuts 522 move in opposite directions. Similarly, when the nuts 522 move, they also drive the lead screw 521 to rotate.

[0078] A damping structure is provided at the rotational center of the lead screw 521. This structure increases the resistance encountered by the lead screw 521 during rotation, ensuring that the lead screw 521 rotates only when the external force applied exceeds a preset value, thereby maintaining the cable 600 in a constant state of tension. Specifically, the damping structure includes a damper 523, which is fixedly connected to the turntable 200. The power output end of the damper 523 is in driving connection with the lead screw 521.

[0079] During operation, clamping mechanism A is in a clamped state, while clamping mechanism B is in a released state. When the reel assembly reels cable 700, a force is applied to clamping mechanism A via cable 600, driving clamping mechanism A from the clamped position to the released position. During this process, clamping mechanism A applies a force to lead screw 521 via its corresponding nut 522, driving lead screw 521 to rotate in a first direction, thereby driving clamping mechanism B from the released position to the clamped position via lead screw 521.

[0080] When clamping mechanism A moves to the release position, it switches from the clamped state to the released state, and clamping mechanism B moves to the clamped position, switching from the released state to the clamped state. When the reel assembly reels cable 700, it applies a force to clamping mechanism B via cable 600, driving clamping mechanism B from the clamped position to the released position. During this process, clamping mechanism B applies a force to lead screw 521 via its corresponding nut 522, driving lead screw 521 to rotate in the second direction, thereby driving clamping mechanism A from the released position to the clamped position via lead screw 521.

[0081] The driving mechanism in this embodiment has a simple structure and a reasonable design, and can drive the two clamping mechanisms to move without an additional power device, thereby having a low cost.

[0082] like Figure 1-13 As shown, in this embodiment, the unloading unit further includes a position sensor 524 .

[0083] The position sensors 524 are fixedly connected to the turntable 200 . Four position sensors 524 are provided. The four position sensors 524 correspond to the clamping position and the releasing position of the two clamping mechanisms respectively.

[0084] When the position sensor 524 in the clamping position detects that the corresponding clamping mechanism is in the current position, the controller controls the clamping mechanism to switch from the released state to the clamped state; when the position sensor 524 in the release position detects that the corresponding clamping mechanism is in the current position, the controller controls the clamping mechanism to switch from the clamped state to the released state.

[0085] like Figure 1-13 As shown, in this embodiment, a fixed electrode ring 531 and a movable electrode 532 are also included.

[0086] The fixed electrode ring 531 is coaxially disposed with the turntable 200 and fixedly connected to the frame 100. Two fixed electrode rings 531 are provided, and the two fixed electrode rings 531 are electrically connected to the positive and negative poles of the output circuit of the power supply, respectively. The mobile electrode 532 is coaxially disposed with the turntable 200 and fixedly connected to the turntable 200. Two mobile electrodes 532 are provided, and the two mobile electrodes 532 correspond to the two fixed electrodes, and the two mobile electrodes 532 are electrically connected to the positive and negative poles of the input circuit of the power element provided on the turntable 200, respectively. Specifically, the power element includes an electromagnet 514, a motor, a position sensor 524, and the like.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures, and techniques are not shown in detail so as not to obscure the understanding of this description.

[0088] Finally, it should be noted that 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 above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
