Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0026] like Figures 1 to 5As shown, the external cable wrapping device 100 of this utility model includes a wrapping assembly 1 for wrapping cables, a guide part 2 for guiding cables into the wrapping assembly 1, a buffer 3 for placing wrapping tape, a second grid frame 4, a support platform 5, a protective cover 6, and a control unit.
[0027] The wrapping assembly 1, the guide part 2, and the buffer part 3 are disposed on the support platform 5.
[0028] The protective cover 6 is disposed on the support platform 5. The wrapping assembly 1 and the buffer 3 are disposed inside the protective cover 6. The protective cover 6 is provided with a door 61, which is used to expose the wrapping assembly 1 and the buffer 3, so as to facilitate the installation of the wrapping roll, maintenance, etc.
[0029] The wrapping assembly 1 includes a wrapping disc 11, a drive motor 12, a gear set 13 connecting the drive motor 12 and the wrapping disc 11, and a support beam 14.
[0030] The wrapping reel 11 is provided with a placement reel 111 for placing the wrapping roll and a rotating reel 112 coaxially arranged and fixedly connected to the placement reel 111. The rotating reel 112 is used to connect to the gear set 13, and the placement reel 111 is located on the side of the rotating reel 112 away from the support beam 14. Multiple wrapping tape fixing shafts 113 are protruding from the rotating reel 112 toward the side away from the support beam 14, and the multiple wrapping tape fixing shafts 113 are arranged in a circumferential array.
[0031] The drive motor 12 drives the gear set 13 and the wrapping reel 11 to rotate. In this embodiment, the drive motor 12 is a servo motor, replacing a conventional three-phase motor. Besides controlling the rotation speed of the wrapping reel 11, the servo motor also controls the wrapping tension. Tension control effectively tightens and compacts the wrapping tape during the wrapping process, ensuring the tightness and uniformity of the wrapping. This function is crucial for ensuring a tight fit between the wrapping tape and the cable, helping to prevent the wrapping tape from loosening or falling off in subsequent processes. Simultaneously, tightening and compaction also improves the overall mechanical strength and durability of the cable.
[0032] More specifically, tension control can be achieved through the following methods:
[0033] (1) Closed-loop control
[0034] Tension feedback device: A tension sensor is installed in the system to measure the tension in real time and feed it back to the controller, forming a closed-loop control circuit. For example, in roll material handling equipment in industries such as printing and papermaking, the sensor can be installed at the inlet and outlet positions of the roll material to accurately detect tension changes.
[0035] PID control algorithm: Based on the deviation between the tension setpoint and the feedback value, the controller uses a PID algorithm to calculate and output a control signal, automatically adjusting the speed and torque of the servo motor to stabilize the tension at the setpoint. In practical applications, the PID parameters need to be adjusted appropriately according to system characteristics and control requirements.
[0036] (2) Combination of speed control mode and torque control mode
[0037] Unwinding process: During unwinding, the servo motor usually operates in torque control mode, providing torque that matches the tension of the roll. As the roll diameter decreases, the torque output is automatically adjusted according to the relationship between torque and tension to maintain constant tension.
[0038] Rewinding process: In the initial stage of rewinding, speed control mode can be used to synchronize the rewinding speed with the unwinding speed. When the roll reaches a certain diameter, switch to torque control mode to maintain the rewinding tension by gradually increasing the torque.
[0039] (3) Position-based tension control
[0040] Encoder Feedback: The servo motor is equipped with a high-precision encoder that provides real-time feedback on the motor's position. By precisely controlling the motor's position and movement distance, precise tension control is indirectly achieved. For example, in textile machinery, the encoder can be used to control the servo motor's rotation based on the fabric's conveying distance and speed requirements, ensuring uniform fabric tension.
[0041] Electronic cam control: Based on the production process requirements, an electronic cam curve is set so that the servo motor runs according to a specific position-tension relationship and outputs corresponding tension at different position points, thereby realizing a complex tension control curve.
[0042] The gear set 13 includes a driving gear 131 connected to the drive motor 12, a first driven gear 132 meshing with the driving gear 131, and a second driven gear 133 meshing with the first driven gear 132. The second driven gear 133 is coaxially connected to the wrapping disc 11.
[0043] In this embodiment, the gear set 13 is provided with three gears. The transmission ratio control of the three gears is more reliable and can improve the wrapping quality.
[0044] The support beam 14 is located between the wrapping disc 11 and the guide part 2. The support beam 14 has a through hole 141 for the cable to pass through along the axial direction of the wrapping disc 11. The gear set 13 is rotatably connected to the support beam 14.
[0045] The control unit is connected to the drive motor 12 via a control line. The drive motor 12 is connected to a power line. The support beam 14 is hollow, and the power line and control line are housed or partially housed within the support beam 14.
[0046] In this embodiment, the support beam 14 protrudes from the protective cover 6 to facilitate wiring.
[0047] The buffer 3 and the guide 2 are located on both sides of the wrapping assembly 1. Furthermore, the guide 2 is located at the cable entry end of the wrapping assembly 1, while the buffer 3 is located at the cable wrapping end of the wrapping assembly 1.
[0048] The buffer 3 is coaxially arranged with the wrapping tray 11, and a through hole 31 for the cable to pass through is provided in the middle of the buffer 3 along the axial direction of the wrapping tray 11. In this embodiment, the buffer 3 is a hollow column, and its outer diameter is equal to that of the placement tray 111, which can just fix the wrapping roll. In this embodiment, the axial length of the buffer 3 is greater than the length of the placement tray 111, so that multiple wrapping rolls can be placed, further extending the one-time working time. When the wrapping rolls on the placement tray 111 are used up or almost used up, it is only necessary to stop the work for a short time and move the wrapping tape on the buffer 3 directly to the placement tray 111 along the axial direction to fasten it, which greatly reduces the downtime.
[0049] In this embodiment, the support platform 5 is provided with an upwardly extending buffer beam 51 to support the buffer member 3. Additionally, in this embodiment, the buffer member 3 is columnar; in other embodiments, it can also be of other shapes, as long as a hole for a cable to pass through is formed in the middle, and the external dimensions allow for winding and insertion.
[0050] The guide part 2 is used to reduce the swaying amplitude when the cable enters the wrapping assembly 1.
[0051] In one embodiment, the guide portion 2 includes a mounting frame 21, a guide bracket 22 disposed on the mounting frame 21, and a guide wheel 23 mounted on the guide bracket 22. The guide bracket 22 is provided with a guide groove 221 extending in the height direction, and the guide wheel 23 is provided with a guide shaft 24. The guide shaft 24 is disposed in the guide groove 221 and is adjustable along the extension direction of the guide groove 221.
[0052] When the cable to be wrapped is thick, a guide wheel 23 is used to guide the cable. After production, the cable enters the through-hole 141 of the support beam 14 from below the guide wheel 23, and then is wrapped. By providing a guide groove 221, the vertical position of the guide wheel 23 can be adjusted, thereby adjusting the angle at which the cable enters the through-hole 141. Compared to a single entry angle, this embodiment can adjust the entry angle of the cable for different types of cables, thus not limiting the wrapping method and path, making the wrapping process more flexible and improving the protective effect of the wrapping.
[0053] When the cable to be wrapped is thin, the guide part 2 includes a first grid frame 25, which includes two first horizontal beams with adjustable spacing and two first vertical beams with adjustable spacing. The first horizontal beams and the first vertical beams enclose a first threading area for the cable to pass through. The first grid frame 25 is mounted on the mounting frame 21.
[0054] Thinner cables move faster and sway more. In this embodiment, the first grid frame 25 is provided to reduce the cable's buffering force and sway amplitude. In addition, by providing a monitoring adjustable first crossbeam, the angle at which the cable enters the wire hole 141 can also be adjusted, which has the same effect as the guide wheel 23, and will not be described in detail here.
[0055] It should be emphasized that in some embodiments, the guide part 2 can be configured as a guide wheel 23, in some embodiments, the guide part 2 can be configured as a first grid frame 25, and in other embodiments, both the guide wheel 23 and the first grid frame 25 can be provided simultaneously to allow for flexible selection for cables of different diameters.
[0056] In some embodiments, a second grid frame 4 is provided to handle the wrapping of thinner cables, mainly to control the swaying amplitude of the cable after wrapping.
[0057] The second grid frame 4 is located on the side of the buffer 3 away from the wrapping assembly 1. The second grid frame 4 is used for the cable to pass through after wrapping. The second grid frame 4 includes two second horizontal beams 41 with adjustable spacing and two second vertical beams 42 with adjustable spacing. The second horizontal beams 41 and the second vertical beams 42 enclose a second cable passing area 43 for the cable to pass through.
[0058] The external cable wrapping device 100 of this utility model is used as follows: Select the appropriate wrapping tape according to the cable to be wrapped, install the wrapping roll on the placement tray 111, and simultaneously place multiple wrapping rolls on the buffer 3 as spares. Preset the speed and tension of the drive motor 12 in the control unit. Select either the first grid frame 25 or the guide wheel 23 according to different cable diameters, and adjust the height. Move the external cable wrapping device 100 to the output end of the braiding machine, pass the braided cable through the guide part 2 into the wrapping assembly 1 for wrapping, and then pass the wrapped cable sequentially through the buffer 3 and the second grid frame 4 for winding. When the wrapping rolls on the placement tray 111 are used up or nearly used up, pause the wrapping, move the wrapping rolls on the buffer 3 to the placement tray 111, and then restart.
[0059] The external cable wrapping device 100 of this utility model, by setting a buffer 3, can quickly replace the wrapping roll during the production process, thereby achieving efficient and continuous wrapping operations; by setting the drive motor 12 as a servo motor, tension control can be performed, thereby reasonably controlling the wrapping angle and overlap rate, ensuring the shielding performance and mechanical strength of the cable.
[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
