Description

Technical Field

[0001] This utility model belongs to the field of cable production, specifically a cable production fork twister wrapping device. Background Technology

[0002] As a key carrier for power transmission and signal transmission, the production quality of cables directly affects the normal operation of various industries. In the cable production process, the cable wrapping machine is an indispensable piece of equipment. It tightly wraps the cable surface with wrapping tape, serving functions such as insulation, protection, and identification.

[0003] However, most existing cable production forklift wrapping devices rely on manual tension adjustment based on experience, or employ simple mechanical friction or counterweight tension adjustment structures. These methods struggle to provide real-time, precise tension adjustment based on actual production factors such as changes in cable production speed and variations in wrapping tape material (e.g., different thicknesses and elasticities of wrapping tape). Excessive wrapping tape tension can easily lead to tape breakage and damage to the cable's outer surface, reducing cable quality; conversely, insufficient tension will cause the wrapping layer to loosen, failing to effectively achieve insulation and protection functions, severely impacting cable performance and lifespan. Furthermore, traditional adjustment methods often require significant time for re-adjustment when changing to produce different cable specifications, resulting in low production efficiency and high production costs.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] As attached Figure 1 To be continued Figure 4 As shown:

[0022] This utility model provides a cable production fork twister wrapping device, which includes a basic structure of a speed reducer 1, a wrapping disc 2, a connecting seat 3, a brake 4 and a mounting disc 5. The tension adjustment component 6 realizes adaptive adjustment and precise guidance of the wrapping tape tension to ensure stable cable wrapping quality.

[0023] As attached Figure 1 As shown: The speed reducer 1 serves as the power source for the wrapping device, and its output shaft is connected to the wrapping disc 2, providing stable rotational power to the wrapping disc 2. The speed reducer 1 is equipped with guide holes coaxially distributed with the wrapping disc 2. These guide holes guide the wrapping tape through, ensuring the accuracy of the initial path of the wrapping tape. The speed reducer 1 is bolted to the frame of the winch, and the installation position ensures that the output shaft and the axis of the wrapping disc 2 are aligned at the same height for easy power transmission.

[0024] As attached Figure 1 As shown: The wrapping reel 2 is connected to the output shaft of the speed reducer 1 and rotates under the drive of the speed reducer 1 to wrap the wrapping tape around the cable. The wrapping reel 2 is fixed to the output shaft by a key connection to ensure the reliability and stability of the connection. The rotational speed and stability of the wrapping reel 2 directly affect the wrapping effect of the wrapping tape. A stable rotational speed allows the wrapping tape to be evenly wrapped around the cable surface, improving the appearance quality and performance of the cable.

[0025] As attached Figure 1 As shown: Connector 3 is mounted on wrapping disc 2, and brake 4 is mounted on connector 3. By controlling brake 4, the start and stop of the wrapping process and speed adjustment are achieved. When it is necessary to stop wrapping or adjust the wrapping speed, brake 4 can act quickly to ensure precise control of the wrapping process and avoid excessive or loose wrapping due to inertia.

[0026] As attached Figure 1 To be continued Figure 4 As shown: Mounting disc 5 is sleeved on the outside of the output shaft of brake 4, and tension adjustment assembly 6 is mounted on mounting disc 5.

[0027] As attached Figure 2 To be continued Figure 4 As shown: The tension adjustment assembly 6 includes an adjustment wheel 601, a connecting shaft 602, a floating magnetic ring 603, and an adjustment unit 605. The adjustment wheel 601 is located at one end of the connecting shaft 602 and is used to guide the wrapping tape. The adjustment wheel 601 is rotatably mounted on the connecting shaft 602 via bearings, allowing for flexible rotation and reducing friction during the guiding process of the wrapping tape. Its installation position is precisely calculated to guide the wrapping tape along the correct path into the wrapping area, ensuring the neatness and accuracy of the wrapping tape winding.

[0028] As attached Figure 2 To be continued Figure 4 As shown, the connecting shaft 602 includes a connecting shaft body 6022 slidably disposed within the limiting guide groove 7 and a limiting block 6021 disposed on the connecting shaft body 6022. The limiting block 6021 is located within the notch of the limiting guide groove 7. This design allows the connecting shaft 602 to slide along the axial direction of the mounting plate 5 within the limiting guide groove 7. Simultaneously, the engagement of the limiting block 6021 with the notch restricts the rotation of the connecting shaft 602, ensuring the stability of the guiding direction of the adjusting wheel 601. The sliding installation method of the connecting shaft 602 provides a structural basis for the subsequent adaptive adjustment of the wrapping tape tension.

[0029] As attached Figure 2 To be continued Figure 4 As shown: A floating magnetic ring 603 is located at the end of the connecting shaft 602 away from the adjusting wheel 601, with 3 to 6 circumferentially arranged positioning magnetic blocks 604 distributed on its outer side. The floating magnetic ring 603 is mounted on the connecting shaft 602 via a bushing, allowing for small axial movements relative to the connecting shaft 602. A magnetic force is generated between the positioning magnetic blocks 604 and the floating magnetic ring 603. When the tension of the wrapping tape changes, the floating magnetic ring 603 can adaptively float and adjust under the combined action of magnetic force and tension, thereby achieving dynamic balance of the wrapping tape tension and ensuring stable wrapping tape tension.

[0030] As attached Figure 2 To be continued Figure 4As shown: Adjustment unit 605 is used to drive positioning magnetic block 604 to move radially along adjustment wheel 601 to further precisely adjust the tension of the wrapping tape. Adjustment unit 605 includes positioning ring 6051 fixedly mounted on mounting plate 5, driving ring 6052 rotatably mounted on positioning ring 6051, driving ring 6052 having multiple limiting guide grooves 7, and moving post 6053 slidably mounted within limiting guide grooves 7. The end of moving post 6053 is fixedly connected to slider 6054, slider 6054 slidably mounted within a groove of positioning ring 6051, and guide post 6055 is also provided within the groove, one of guide post 6055 being threadedly connected to slider 6054. By rotating driving ring 6052, moving post 6053 slides within limiting guide groove 7, thereby causing slider 6054 to move along guide post 6055 within the groove, thus adjusting the position of positioning magnetic block 604. The adjustment unit 605 allows operators to manually or precisely adjust the wrapping tape tension according to different production needs, enhancing the adaptability and flexibility of the device.

[0031] Working Principle: The speed reducer 1 is bolted to a designated position on the winch frame. Starting the speed reducer 1 rotates the wrapping reel 2. When the cable passes through the guide hole of the speed reducer 1 into the wrapping reel 2, the wrapping tape wraps around the cable after passing over the adjusting wheel 601. During the wrapping process, if the wrapping tape tension increases, the tension acts on the adjusting wheel 601, causing the connecting shaft 602 to slide outward along the limiting guide groove 7, thus moving the floating magnetic ring 603 outward. At this time, the distance between the floating magnetic ring 603 and the positioning magnetic block 604 decreases, the magnetic attraction increases, generating an inward restoring force to suppress further tension increases. If the wrapping tape tension decreases, the floating magnetic ring 603 moves inward under the magnetic attraction, restoring tension balance. By rotating the drive ring 6052, all positioning magnetic blocks 604 can be moved radially synchronously, adjusting the initial distance between the floating magnetic ring 603 and the positioning magnetic blocks 604, thereby achieving pre-adjustment of the wrapping tape tension to accommodate different specifications of wrapping tape and cables.
