[0035] Please refer to Figures 1-8 And the existing winding cable rewinding loading, the cable restriction area is generally fixed during winding, and the winding of the cable is uneven, offset and extruded for different size rewinding processing, which increases the error for the later rewinding experiment, and the knot problem is easy to appear, based on this, the application provides a cable rewinding testing machine, which comprises a cable 1 for experiment, a winding disc 2 for winding the cable 1 and a support table 3 for installing the winding disc 2;

[0036] The winding disc 2 comprises a fixed disc 21, and the two sides of the fixed disc 21 are provided with limiting plates 22 for limiting the winding cable 1, and the outer side of one of the limiting plates 22 is provided with a driving motor 23 for driving the limiting plate 22 to rotate;

[0037] The limiting plate 22 comprises a plate body one 221 and a plate body two 225, and an adjusting area 227 is arranged between the plate body one 221 and the plate body two 225 for flat winding with the cable 1;

[0038] The side of the plate body one 221 close to the plate body two 225 is provided with a winding area 223, and the winding area 223 is provided with recessed areas 228 arranged in an annular array for increasing the friction of the cable 1;

[0039] The outer side of the plate body one 221 is provided with an auxiliary groove 229, and the inner side of the auxiliary groove 229 is provided with a limiting block for flat winding of the cable 1.

[0040] The support table 3 can be made of a solid metal material, such as stainless steel or aluminum alloy, to ensure that it has sufficient strength and stability to withstand the weight of the winding disc 2 and the cable 1. The surface of the support table 3 should be flat to avoid affecting the normal operation of the winding disc 2 due to uneven surface.

[0041] The winding disc 2 is installed on the support table 3. The fixed disc 21 of the winding disc 2 can be connected with the support table 3 through a bearing to ensure that the fixed disc 21 can rotate flexibly on the support table 3. The bearing should be selected in a high-precision and low-friction type to reduce energy loss and noise during rotation.

[0042] The limiting plates 22 are installed on both sides of the fixed disc 21, and the plate body one 221 and the plate body two 225 of the limiting plate 22 can be connected in a detachable manner, such as bolt connection, to facilitate adjustment of the size of the adjusting area 227 according to the size of the different cables 1. When installing one of the limiting plates 22, the driving motor 23 is installed on the outer side thereof. The driving motor 23 can be connected with the limiting plate 22 through a shaft coupling to ensure that the power of the driving motor 23 can be stably transmitted to the limiting plate 22 to drive the fixed disc 21 and the cable 1 to rotate.

[0043] To improve the speed control of winding, the driving motor 23 can be equipped with a suitable controller, which can accurately control the speed and direction of the driving motor 23 according to the experimental requirements, so as to realize different rewinding speed and direction.

[0044] A recessed area 228 arranged in a ring array is processed in the winding area 223 of the plate body one 221 close to the plate body two 225. The recessed area 228 can be made by milling, stamping and other processing techniques, and its shape can be semicircular, trapezoidal, etc.

[0045] An auxiliary groove 229 is processed on the outside of the plate body one 221, and a limiting block is installed inside the auxiliary groove 229. The limiting block can be made of rubber or plastic and other materials with certain elasticity to avoid damaging the cable 1. The shape of the limiting block can be wedge-shaped or arc-shaped, and its height and width can be adjusted according to the size of the cable 1 to ensure effective flat laying and guiding of the cable 1.

[0046] One end of the cable 1 used for the experiment is fixed on the fixed disc 21 of the winding disc 2, and the driving motor 23 is started to make the winding disc 2 start rotating, and the rewinding operation of the cable 1 is carried out. During the rewinding process, the adjusting area 227 between the plate body one 221 and the plate body two 225 is adjusted according to the size and winding condition of the cable 1 to ensure that the cable 1 can be wound flat on the winding disc 2.

[0047] The state of the cable 1 during winding is observed, and the speed of the driving motor 23 and the position of the limiting block are adjusted to further optimize the winding effect of the cable 1 and minimize the extrusion and friction between the cables 1.

[0048] The limiting plates 22 on both sides of the fixed disc 21 can effectively limit the lateral movement of the cable 1 during the rewinding process, avoiding problems such as uneven winding, mutual misplacement and extrusion of the cable 1, ensuring that the cable 1 can be wound in the predetermined manner, and improving the flatness and neatness of the cable rewinding.

[0049] The adjusting area 227 between the plate body one 221 and the plate body two 225 can be flexibly adjusted according to different sizes and specifications of the cable 1, so that the testing machine can adapt to various types of cable 1 rewinding experiments, improving the versatility and applicability of the equipment.

[0050] The recessed area 228 arranged in the winding area 223 increases the friction between the cable 1 and the winding disc 2, making the cable 1 more stable during winding and less likely to slip or loosen, reducing the problem of uneven winding and knotting caused by the cable 1 slipping, and improving the stability and reliability of the cable rewinding.

[0051] The limiting block in the auxiliary groove 229 outside the plate body 221 can guide the flat laying of the cable 1, ensure that the cable 1 remains parallel during winding, avoid the cable 1 from stacking and crossing, and further improve the quality and effect of cable rewinding.

[0052] By ensuring the flatness and stability of the cable winding, the extrusion and friction between the cables are reduced, the risk of damage to the outer sheath of the cable is reduced, the insulation layer inside the cable is protected, the insulation performance of the cable is ensured, and the safety hazards such as electric leakage and short circuit are reduced.

[0053] The flat winding method avoids the twisting or stretching of the core inside the cable, ensures the electrical performance of the cable, improves the service life and reliability of the cable, and provides accurate experimental data for the quality detection and performance research of the cable.

[0054] The bottom of the driving motor 23 is provided with a base 24, and the base 24 is adapted to the support table 3.

[0055] The inner side of the plate body 221 is provided with one or more positioning holes 222, and a telescopic piece is installed at the positioning hole 222, which is used to adjust the distance of the installation area in cooperation with the plate body 225.

[0056] The side of the plate body 225 close to the plate body 221 is provided with a sealing groove 2210, and the sealing groove 2210 is adapted to the winding area 223.

[0057] The side of the plate body 225 and the plate body 221 away from each other is provided with one or more mounting grooves 224 arranged in a ring array.

[0058] The positioning holes 222 on the inner side of the plate body 221 are uniformly distributed according to the common specifications of the size of the cable 1, and the telescopic piece is selected as an electric push rod, which is fixed on the positioning hole 222 by bolts. The operator can adjust the telescopic length of the electric push rod according to the diameter of the cable 1 and the winding requirements, so as to change the distance between the plate body 221 and the plate body 225, for example, for thicker cable 1, the electric push rod is elongated to increase the distance of the installation area; for thinner cable 1, the electric push rod is shortened to reduce the distance, so as to achieve the best winding effect.

[0059] The sealing groove 2210 on the plate body two 225 is embedded with a sealing ring made of rubber material, and the size of the sealing ring is accurately matched with the winding area 223. During installation, the sealing ring is tightly attached to the edge of the winding area 223. When the cable 1 is winding, the sealing ring can prevent dust and debris from entering the winding area 223, avoiding the influence of these impurities on the friction between the cable 1 and the recess of the winding area 223, ensuring the stability of the cable 1 winding. At the same time, the sealing ring can also play a certain buffering role, reducing the collision and friction between the cable 1 and the plate body two 225, protecting the outer sheath of the cable 1.

[0060] The plate body one 221 and the plate body two 225 are provided with four mounting slots 224 arranged in a ring array on the side away from each other. The mounting slots 224 are rectangular in shape and have a moderate depth.

[0061] The base 24 is adaptively installed with the support table 3, and the anti-skid design and shock absorption measures can effectively reduce the vibration and displacement of the driving motor 23 during operation, ensuring the stable operation of the motor, so that the rotation of the winding disc 2 is more stable, improving the precision and quality of the cable rewinding.

[0062] The use of rubber gaskets reduces vibration transmission and reduces noise generated during motor operation, improving the working environment.

[0063] The telescopic piece can flexibly adjust the distance between the plate body one 221 and the plate body two 225 according to the size of different cables 1, so that the cable rewinding tester can adapt to the rewinding needs of cables 1 of various specifications, improving the versatility and applicability of the equipment.

[0064] The sealing ring in the sealing groove 2210 can prevent dust and debris from entering the winding area 223, protect the outer sheath of the cable 1 from damage, and ensure the stability of the friction between the cable 1 and the winding area 223, improving the stability and quality of the cable 1 winding.

[0065] The mounting slots 224 are provided with extension plates installed by fasteners, forming a limiting area radially outward from the center, which is used to support the winding cable 1.

[0066] The inner side of the plate body two 225 is provided with a positioning hole 222 corresponding to the plate body one 221, which is used to cooperate with the plate body one 221 to install the telescopic piece.

[0067] The plate body one 221 and the plate body two 225 are provided with a through mounting hole 226 in the middle, and the inner side of the mounting hole 226 is adapted to the driving shaft of the driving motor 23.

[0068] The installation groove 224 is a U-shaped groove that ensures that the extension plate can be tightly embedded therein. High-strength bolts and nut combinations are selected for fastening. The bolt head is in the form of an internal hex, which facilitates tightening with a tool. The extension plate is made of aluminum alloy, which is light in weight and high in strength. When installing the extension plate, first align the connecting part of the extension plate with the installation groove 224, slowly push it in, then use the bolt to pass through the corresponding hole on the extension plate, and cooperate with the threaded hole at the bottom of the installation groove 224, and tighten with a nut. After the installation of multiple extension plates is completed, a limiting area that radiates outward from the center at equal intervals is formed. For example, when rewinding a larger diameter cable, the number of extension plates can be increased to expand the range of the limiting area and provide more stable support for the cable; for smaller diameter cables, the number of extension plates can be appropriately reduced.

[0069] The positioning holes 222 on the inner side of the second plate body 225 accurately correspond to the positioning holes 222 on the first plate body 221. The diameter tolerance of the positioning holes 222 is controlled within a very small range to ensure that the telescopic member can be smoothly installed and maintain good coaxiality after installation. The installation holes 226 in the middle of the first plate body 221 and the second plate body 225 are processed using high-precision boring technology to ensure that the inner diameter size precision and surface roughness of the installation holes 226 meet the requirements. Key grooves are designed on the inner side of the installation holes 226. The driving shaft of the driving motor 23 also has corresponding key grooves. The driving shaft and the installation holes 226 are connected together through a flat key to reliably transmit torque. When installing, apply an appropriate amount of lubricating oil to the driving shaft and the installation holes 226, then successively sleeve the first plate body 221 and the second plate body 225 on the driving shaft, align the key grooves, and insert the flat key. To prevent the plate body from axially moving during rotation, elastic shaft collars are installed at both ends of the driving shaft for axial positioning.

[0070] The equidistantly radiating limiting areas formed by the extension plates can provide all-around support for the wound cable, reducing the cable's shaking and deviation during rewinding, especially for large diameter or heavy cables, effectively preventing the cable from collapsing or deforming due to its own weight or tension during winding, and improving the quality and neatness of cable rewinding.

[0071] The number and distribution of extension plates can be flexibly adjusted according to the size and characteristics of different cables, enabling the equipment to adapt to the rewinding needs of various specifications of cables, enhancing the versatility and practicality of the equipment.

[0072] The corresponding positioning holes 222 of the second plate body 225 and the first plate body 221 facilitate accurate installation of the telescopic member. In combination with the use of a hydraulic telescopic rod, the spacing between the first plate body 221 and the second plate body 225 can be accurately adjusted, which enables the equipment to provide the most suitable winding space according to the diameter of different cables and winding requirements, ensuring the flatness and tightness of cable winding, reducing the squeezing and friction between cables, and reducing the risk of cable damage.

[0073] The telescopic part is firmly installed and has good coaxiality, which can ensure the stability of the plate body 221 and the plate body 225 during rotation, reduce noise and vibration caused by part shaking, and prolong the service life of the equipment.

[0074] The mounting hole 226 is connected with the driving shaft through a key, which can ensure that the torque of the driving motor 23 is reliably transmitted to the plate body 221 and the plate body 225, so that the winding disc 2 can stably rotate, the continuity and stability of the cable rewinding process are ensured, the mounting hole 226 and the driving shaft are cooperatively designed, and the axial positioning mode of the elastic retaining ring for the shaft makes the installation and disassembly of the plate body more convenient, facilitates the daily maintenance and overhaul of the equipment, and improves the use efficiency of the equipment.

[0075] The above only describes the embodiments of the present application and is not used to limit the present application. The present application can be variously changed and modified by those skilled in the art.
