Description

Technical Field

[0001] This utility model belongs to the field of cable production application equipment, and in particular relates to an adjustable mica tape wrapping device for cable production. Background Technology

[0002] Mica tape is a commonly used cable insulation material. It refers to a strip-shaped material made of mica sheets, possessing excellent insulation properties and high-temperature resistance, making it suitable for insulating cables, transformers, motors, and other electrical equipment. By wrapping mica tape around conductors or insulation layers, it provides insulation protection and high-temperature resistance to cables, while also preventing arcing and moisture absorption of the insulation layer.

[0003] Polyester tape is also an important cable material. It has high insulation resistance, which ensures the electrical safety of the cable during use. At the same time, polyester tape has high dielectric strength, which can withstand high voltage without being broken down, thus protecting the conductors inside the cable.

[0004] In the production of existing cables, mica tape and polyester tape are generally wrapped around the conductor or insulation layer using a wrapping method. Since the existing design usually uses polyester tape to wrap around mica tape and the wrapping angle of the polyester tape and mica tape is the same, only two feeding units need to be set on one turntable.

[0005] While the above structure can meet the winding requirements of mica tape and polyester tape, it requires that the winding thickness of the mica tape and polyester tape be the same. However, in actual production, due to the needs of different application scenarios, there may be situations where the thickness of the mica tape is required to be greater than that of the polyester tape. Existing equipment cannot achieve this function. Therefore, it is necessary to wrap the tape twice (once with only mica tape and once with only polyester tape), which increases production costs and reduces production efficiency. Utility Model Content

[0006] This invention addresses the technical problems existing in the wrapping of mica tape and polyester tape with different thicknesses. It proposes an adjustable mica tape wrapping device for cable production that is reasonably designed, simple in structure, easy to process, and can be improved upon based on existing technology to achieve asynchronous winding of mica tape and polyester tape.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides an adjustable mica tape wrapping device for cable production, including a frame and a rotating shaft tube. The rotating shaft tube is rotatably mounted on the frame. One end of the rotating shaft tube is provided with a wrapping disc. The wrapping disc is provided with a mica tape feeding unit.

[0008] Preferably, a gear ring is fitted on the outer wall of the auxiliary wrapping disc, a drive motor is provided on the frame, and the power end of the drive motor is connected to a gear that meshes with the gear ring. The auxiliary wrapping disc is rotated on the fixed tube by the drive motor.

Detailed Implementation

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, such as Figure 1 , Figure 2As shown, this embodiment aims to achieve different rotation speeds for the mica tape feeding unit 3 and the polyester tape feeding unit 6, so as to increase the winding thickness of the mica tape while simultaneously winding the mica tape and the polyester tape. To this end, the adjustable mica tape wrapping device for cable production provided in this embodiment includes a frame 1 and a rotating shaft tube 21. In this embodiment, the frame 1 includes a fixed base for fixing to the ground or platform and a vertical plate vertically set on the fixed base. A fixed tube 11 is set on the top of the vertical plate. The fixed tube 11 is fixed to the vertical plate by welding or bolting. A bearing is installed inside the fixed tube 11, and the rotating shaft tube 21 is installed inside the bearing. In this way, under the application of external force, the rotating shaft tube 21 is rotated on the frame 1. In this embodiment, the two ends of the rotating shaft tube 21 extend out of the two ends of the fixed tube 11. One end is used to connect to the rotating shaft tube drive mechanism 22, and the other end is connected to the wrapping disc 2. The rotating shaft tube drive mechanism 22 can be a hollow rotating platform or a synchronous belt driven by a motor provided in this embodiment. A drive shaft is provided at the other end of the synchronous belt, and a drive gear is mounted on the drive shaft. A meshing gear that meshes with the drive gear is provided on the rotating shaft tube 21, thus ensuring that the cable passes through the rotating shaft tube 21.

[0020] Of course, a mica tape feeding unit 3 is provided on the wrapping reel 2, and a polyester tape feeding unit 6 is provided on the frame 1. The above structures are common existing structures, so they will not be described in detail in this embodiment.

[0021] To simultaneously wind mica tape and polyester tape while ensuring the mica tape thickness is greater than the polyester tape thickness, the winding angle of the mica tape needs to be adjusted to be smaller. Simultaneously, its rotational speed must be greater than that of the polyester tape. Therefore, the mica tape feeding unit 3 and the polyester tape feeding unit 6 must operate at different speeds. To this end, an auxiliary winding disc 4 is fitted around the fixed tube 11, and a bearing is also installed between the auxiliary winding disc 4 and the fixed tube 11. Under external force, the auxiliary winding disc 4 rotates on the fixed tube 11. In this embodiment, a gear ring 41 is fitted on the outer wall of the auxiliary winding disc 4, and a drive motor 5 is installed on the vertical plate. The power end of the drive motor 5 is connected to a gear 51 that meshes with the gear ring 41. The auxiliary winding disc 4 is rotated on the fixed tube 11 via the drive motor 5. Meanwhile, the polyester tape feeding unit 6 is installed on the auxiliary winding disc 4. In this way, the mica tape feeding unit 3 and the polyester tape feeding unit 6 can be controlled by different mechanisms, so that the mica tape feeding unit 3 and the polyester tape feeding unit 6 can be fed at different speeds.

[0022] To simplify the angle adjustment mechanism of the mica tape feeding unit 3 and the polyester tape feeding unit 6, in this embodiment, a fixing mechanism 7 for fixing the mica tape feeding unit 3 or the polyester tape feeding unit 6 is provided on both the wrapping reel 2 and the auxiliary wrapping reel 4. Specifically, the fixing mechanism 7 includes a fixing plate 71 for fixing on the wrapping reel 2 or the auxiliary wrapping reel 4 and a connecting plate 72 vertically arranged on the fixing plate 71. In this embodiment, considering that the feeding unit generally needs to be placed at an angle, the connecting plate 72 is an inclined plate.

[0023] Meanwhile, a connecting hole 721 is provided on the connecting plate 72, and an adjusting plate 73 is provided on both the mica tape feeding unit 3 and the polyester tape feeding unit 6. An arc-shaped slot 731 is provided on the adjusting plate 73, and the arc-shaped slot 731 and the connecting hole 721 are connected by bolts. In this way, by controlling the position of the connecting hole 721 at the arc-shaped slot 731, the angle of the mica tape feeding unit 3 and the polyester tape feeding unit 6 can be changed, thereby changing their winding angle.

[0024] Considering the instability of relying solely on the connecting hole 721 and the arc-shaped slot 731 for fixation, an auxiliary connecting hole is also provided on the connecting plate 72. This connecting hole is located on the side of the connecting hole 721 away from the fixing plate 71. A rotation auxiliary hole 732 is provided on the adjusting plate 73, and the auxiliary connecting hole and the rotation hole 732 are connected by bolts. In this way, the feeding unit can adjust its angle around the rotation hole 732, while simultaneously achieving two-point fixation, ensuring the stability of the feeding unit's fixation.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
