Description

Technical Field

[0001] This utility model relates to the stranding process of high-voltage wire cores in high-voltage cables, and particularly to the feeding device for cable crepe paper. Background Technology

[0002] Currently, high-voltage cross-linked polyethylene insulated power cables are used for AC power transmission and distribution systems, and crepe paper is used in split conductors (800mm²). 2 (And above specifications) Internally, it is used to divide the conductor into individual strands, insulating each strand to increase the conductor's surface area and reduce its AC resistance. It has the following functions: 1. Inherent dielectric strength; 2. Thermal stability; 3. Mechanical toughness; 4. Chemical compatibility; 5. Insensitivity to moisture; 6. Radiation resistance; non-toxic and flame retardant.

[0003] Insulating crepe paper is mainly made of plastic sheets. Plastic is a synthetic polymer compound that can be freely shaped. Plastic is a material produced by polymerizing monomer raw materials through synthesis or condensation reactions. It consists of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Its main component is synthetic resin. Insulating crepe paper is used as an insulating material for various electrical equipment such as cables and coils.

[0004] In order to better meet the special requirements of the division between conductor strands in cables, the inventors specially developed and designed a crepe paper feeding device, which led to this invention. Utility Model Content

[0005] The purpose of this invention is to provide a cable crepe paper feeding device to meet the requirements of the cable conductor strand separation process.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A cable crepe paper feeding device has a tower-shaped base with fixed holes at the bottom. The tower surface of the tower-shaped base forms several annular adjustment grooves. Several adjustment blocks that can slide on the adjustment groove are installed on each adjustment groove. The adjustment blocks are positioned on the adjustment groove by means of bolts or other fasteners. The adjustment blocks have guide holes for the crepe paper to pass through.

[0008] The paper guide hole is an arc-shaped hole with both ends curving outwards.

[0009] The width of the paper guide hole of the adjusting block gradually narrows from the bottom to the top of the tower-shaped base.

[0010] The tower base has two to three annular adjustment slots on its surface, and two to three adjustment blocks are installed on each adjustment slot.

[0011] The two sides of the adjusting block form positioning notches corresponding to the adjusting grooves, and the fixing parts are stuck in the positioning notches.

[0012] The bottom surface of the tower-shaped base has a hole for the filling rope to pass through, and the top surface of the tower-shaped base has a hole for the filling rope to pass through.

[0013] The bottom of the tower-shaped base is recessed to form several perforated holes, which are evenly distributed. The perforated holes are bullet-shaped.

[0014] The tower-shaped base is conical, and the fixing holes are located on the bottom surface of the cone.

[0015] With the above solution, the bottom of the tower-shaped base of this utility model is mounted on the frame and used in conjunction with high-voltage stranding equipment. During the production of high-voltage cables, when splitting conductor strands, the conductor strands pass through the tower surface of the tower-shaped base. The corrugated paper is guided through the paper guide hole, fed, and then fully wraps each conductor. Furthermore, filler rope fills the gaps between the conductor strands through the filler rope through-hole and the filler rope perforation, thereby improving the roundness of the stranded conductors.

[0016] Before starting the machine, the present invention can be adjusted for the first time by fixing the hole position, and then adjusted for the second time by sliding the adjustment block through which the crepe paper passes, so that the crepe paper can be adjusted to a suitable guide angle and precise wrapping degree.

[0017] This utility model features a stable and convenient structural design with good safety and mechanical properties. It can provide crepe paper at a suitable angle to ensure the quality of stranded wire core products and precise surface roundness.

[0018] Compared with the folding and feeding paper device, this utility model has higher wrapping accuracy, more precise and adjustable crepe paper guidance, reduced crepe paper breakage rate, reduced material waste rate, ensures reliable cable roundness, improves the quality of high-voltage cable products, and increases the first-pass yield of high-voltage cables.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] It should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the technical features indicated, unless otherwise explicitly defined.

[0029] See Figures 1 to 5 As shown, this utility model discloses a cable crepe paper feeding device, which has a tower-shaped base 1. A fixing hole 2 is provided at the bottom of the tower-shaped base 1, which is used to fix the entire device on a frame for use with high-voltage stranding equipment. The tower surface of the tower-shaped base 1 forms three annular adjustment grooves 3, 5, and 7. Three adjustment blocks 4, 6, and 8 are respectively installed on the three adjustment grooves 3, 5, and 7. The number of adjustment grooves and adjustment blocks is not limited by the accompanying drawings and embodiments, and can be determined according to design requirements and actual needs. The adjustment blocks 4, 6, and 8 can slide on the corresponding adjustment grooves 3, 5, and 7 to achieve the adjustment function. After the adjustment blocks 4, 6, and 8 are adjusted to their positions, they can be fixed with the aid of a fixing member 10 (shown as bolts in the figure; for ease of understanding, only...). Figure 2 and Figure 3 (Some positions are shown) are positioned on adjustment slots 3, 5, and 7, and paper guide holes 9 are opened on adjustment blocks 4, 6, and 8 for crepe paper to pass through.

[0030] The optimized design of this utility model is that the paper guide hole 9 is an arc-shaped hole with both ends curving outwards, which allows the crepe paper to be bent after passing through the paper guide hole 9, so as to better wrap each conductor subsequently. Moreover, the width of the paper guide hole 9 of the adjusting blocks 4, 6, and 8 on the three adjusting slots 3, 5, and 7 gradually narrows from the bottom to the top of the tower-shaped base 1, which further allows the crepe paper to be gradually bent when passing through at least two paper guide holes 9 from the bottom to the top of the tower-shaped base 1, avoiding excessive bending at one time and causing the tape to break, and also making it more conducive to the crepe paper wrapping each conductor.

[0031] To better position the adjusting blocks 4, 6, and 8, positioning notches 11 are formed on both sides of the adjusting blocks 4, 6, and 8 corresponding to the adjusting grooves 3, 5, and 7. The fixing piece 10 is locked at the positioning notch 11, so that the adjusting blocks 4, 6, and 8 are positioned in multiple dimensions, avoiding the offset and deflection of the adjusting blocks 4, 6, and 8, ensuring stable performance, and ensuring the quality of stranded wire core products.

[0032] To improve the roundness of the stranded wire core, a filling rope passage hole 12 is provided on the bottom surface of the tower-shaped base 1, and a filling rope through hole 13 is provided on the top surface of the tower-shaped base 1. The filling rope passes through the filling rope passage hole 12 and the filling rope through hole 13 to fill the gaps between the conductors of each strand of the stranded wire core, thereby improving the roundness of the stranded wire core.

[0033] The bottom of the tower-shaped base 1 of this invention is further recessed to form several hollow holes 14 (five hollow holes 14 are shown in the figure), which are evenly distributed. The hollow holes 14 are preferably designed in a bullet shape. This design can reduce the weight of the device, save manufacturing costs, and further ensure stable performance, good safety performance, and good mechanical properties.

[0034] The present invention further designs the tower-shaped base 1 into a cone shape, which makes the structure more stable. The fixing hole 2 and the filling rope passage hole 12 are set on the bottom surface of the cone, and the filling rope through hole 13 is set on the top of the cone.

[0035] This utility model is mounted on a frame via a tower-shaped base 1 and is used in conjunction with high-voltage stranding equipment. Before starting the machine, the crepe paper is guided through the paper guide holes 9 of the adjusting blocks 4, 6, and 8 on the corresponding adjusting slots 3, 5, and 7. A first coarse adjustment is made through the fixed hole 2, followed by a second fine adjustment by sliding the crepe paper through adjusting blocks 4, 6, or 8, allowing the crepe paper to be adjusted to a suitable guiding angle and precise wrapping degree. This device can not only adjust the guiding of the crepe paper but also its wrapping degree. In particular, the use of three adjusting slots allows for more precise adjustment of the crepe paper's guiding direction, and the wrapping angle of the crepe paper can be adjusted through three sets of adjusting blocks, ensuring that the wrapping degree of each strand of the stranded conductor cable core meets the production process requirements.

[0036] In practical application, during the production of high-voltage cables and the splitting of conductor strands, the conductor strands pass through the tower surface of the tower-shaped base 1. Crepe paper is guided and fed through the paper guide hole 9, then fully wraps each conductor. This invention provides crepe paper at a suitable angle, ensuring the quality of the stranded conductor products and precise surface roundness.

[0037] In summary, the key technology of this utility model is that during the production of high-voltage cables, when splitting conductor strands, the crepe paper fully wraps each conductor. The crepe paper feeding device described in this utility model is proposed, designed, and modified based on existing high-voltage cable production equipment to improve the guiding accuracy of the crepe paper and the wrapping degree of the strands. In addition to retaining the original production functions, the equipment adds 1-3 adjusting blocks, 1-3 adjusting slots, and other accessories, thereby improving the quality of split conductor strands in high-voltage cable products and increasing the product qualification rate.

[0038] The above description is merely an example of the implementation of this utility model and is not intended to limit the scope of protection of this utility model. It should be noted that any equivalent changes made by those skilled in the art after reading this specification, based on the design concept of this case, shall fall within the scope of protection of this case.
