Description

Technical Field

[0001] The present invention belongs to the technical field of twisting devices, and more specifically, relates to a twisting device used in the production of cross-linked polyethylene insulated cables. Background Art

[0002] Cross-linked polyethylene (XLPE) insulated cable is suitable for applications such as power distribution networks. Through chemical or physical methods, the polyethylene molecules in the cable insulation are transformed from a linear molecular structure to a three-dimensional network structure, converting the thermoplastic polyethylene into a thermosetting cross-linked polyethylene. This transformation significantly improves the polyethylene's heat resistance and mechanical properties, reduces shrinkage, and prevents it from melting when heated, while maintaining its excellent electrical properties.

[0003] At present, the following technical problems are found in the twisting device of cross-linked polyethylene insulated cable production: 1. Currently, most cross-linked polyethylene insulated cable twisting devices do not have a mechanism to clean the cables during the production process. When impurities such as oil, metal debris or dust adhere to the cable surface, these impurities will be embedded in the insulation layer during the twisting process, resulting in uneven thickness or damage to the insulation layer, which in turn affects the cable's high-voltage resistance and insulation resistance stability. In addition, the wire core will jitter when passing through the guide hole on the stranding drum. This jitter will cause repeated collision and friction between the wire core and the inner wall of the guide hole. Long-term friction will damage the wire core surface coating.

[0004] 2. Existing twisting devices lack an effective stress relief mechanism after twisting multi-core cables. During the twisting process, complex stress distribution forms within each strand due to factors such as winding order and tension control. Especially under high-temperature conditions, differences in the thermal expansion coefficients of cable materials exacerbate stress concentration. This stress concentration can cause localized plastic deformation in the cable, or even breakage during use, affecting the stability of power or signal transmission. Summary of the Invention

[0007] Preferably, the gear mechanism includes a transmission rod, which is arranged on the coupling seat through a bearing, a third gear is fixedly installed on the left end of the transmission rod, a tooth groove is provided on the circumferential surface of the capstan drum, and the third gear is engaged with the tooth groove on the capstan drum, and a first gear is fixedly installed on the right end of the transmission rod, and a gear timing belt is engaged on the circumferential surface of the first gear.

[0008] Preferably, the rotational vibration mechanism includes two first support rods, the two first support rods are fixedly mounted on the hinge seat, a first limiting ring is fixedly mounted between the two first support rods, a first rotating ring is mounted on the inner wall of the first limiting ring through a bearing, a tooth groove is provided on the circumferential surface of the first rotating ring, the inner wall of the gear synchronous belt is engaged with the tooth groove on the first rotating ring, a connecting plate is fixedly mounted between the two first support rods, four limiting rods are fixedly mounted on the connecting plate, and a collision rubber block is fixedly mounted on the inner wall of the first rotating ring.

[0009] Preferably, the drying mechanism includes four L-shaped connecting frames, the four L-shaped connecting frames are fixedly mounted on the first rotating ring, the side ends of the four L-shaped connecting frames are fixedly mounted with a second rotating ring, the circumferential surface of the second rotating ring is fixedly mounted with a second limiting ring through a bearing, two second support rods are fixedly mounted on the second limiting ring, and two second support rods are fixedly mounted on the two first support rods respectively, at least eight water-absorbing sponge columns are fixedly mounted on the second rotating ring, and an adjustment plate is fixedly mounted on the eight water-absorbing sponge columns, the adjustment plate is rotatably mounted on the second rotating ring through a bearing, the annular anti-static brush is mounted on the inner wall of the adjusting plate and the second rotating ring through bolts, the second fixed plate is fixedly mounted on the adjusting plate, two first fixed plates are fixedly mounted on the second rotating ring, and positioning bolts are provided between the second fixed plate and the first fixed plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, a cleaning mechanism consisting of a wire harness limiting cylinder, an annular cleaning brush, and a second gear is arranged in the stranding drum, and the second gear is engaged with the inner wall of the internal gear, so that when the stranding drum rotates, the cleaning mechanism can rotate synchronously. At this time, the annular cleaning brush can rotate and clean the single cable passing through the wire harness limiting cylinder, effectively removing foreign matter such as oil, impurities, etc. on the surface of the cable, and preventing these substances from destroying the integrity and uniformity of the insulation layer. At the same time, the chamfered corner design and grease coating of the inner wall opening of the wire harness limiting cylinder can greatly reduce the degree of wear of the cable when passing through, thereby ensuring the physical properties of the cable from the source and laying a good foundation for the subsequent stranding process.

[0011] In the present invention, the winding drum and the rotary vibration mechanism are organically linked through the ingenious design of the gear mechanism. Specifically, the tooth grooves on the circumferential surface of the winding drum are engaged with the third gear. When the winding drum rotates, it drives the third gear, the transmission rod and the first gear to rotate synchronously. The first gear then drives the first rotating ring to rotate through the gear timing belt. This transmission process not only realizes the efficient transmission of power, but also enables the rotary vibration mechanism to keep synchronization with the rotation of the winding drum, ensuring that the stress relief operation can be followed up in real time during the cable twisting process, avoiding the local strength reduction of the cable due to stress concentration, and improving the structural stability and service life of the cross-linked polyethylene insulated cable.

[0012] In the present invention, a first rotating ring, a collision rubber block, a connecting plate and a limit stop lever are provided in the rotating vibration mechanism. When the first rotating ring rotates driven by the gear synchronous belt, the collision rubber block on the inner wall will rotate with it and collide with the limit stop lever on the connecting plate. After the collision, the rebound force of the rubber block will act evenly on the multi-core cable passing through the circular hole of the twisting seat. Through multiple circumferential vibrations, the stress balance formed inside the cable due to factors such as the twisting sequence and uneven force on the wire strands is broken, and the stress is redistributed, thereby achieving the purpose of eliminating stress. This design does not require an additional power source and can be achieved only by relying on the linkage of the transmission mechanism. It not only simplifies the structure but also improves the efficiency and uniformity of stress elimination.

[0013] In the present invention, by integrating a water-absorbing sponge column and an annular anti-static brush in the drying mechanism, and utilizing the bolt positioning structure of the adjustment plate, the first fixed plate, and the second fixed plate, flexible switching of functions is achieved. When the air humidity is low, the annular anti-static brush is fixed to the adjustment plate and the inner wall of the second rotating ring. It rotates with the second rotating ring to eliminate static electricity on the surface of the cable, preventing static electricity from absorbing dust, dander and other impurities and affecting the quality of the cable. When in a high humidity environment (relative humidity exceeds 70%), the bolts are removed and the adjustment plate is rotated, so that the water-absorbing sponge column is twisted and contacts the cable, absorbing moisture on its surface, avoiding moisture in the insulation layer and causing a decrease in insulation resistance, thereby ensuring the electrical performance and safety of the cable in different environments.

[0014] In the present invention, through the systematic linkage design of various mechanisms, the rotation of the stranded drum is used as the core power source, which in turn drives the cleaning mechanism, gear mechanism, rotary vibration mechanism and drying mechanism to work together, from the cleaning and guiding of a single cable, to the twisting and stress elimination of multi-core cables, and then to drying or static electricity removal according to the ambient humidity, forming a complete production process chain. This integrated design not only reduces the equipment's footprint and energy consumption, but also improves production efficiency through the precise coordination of transmission components. At the same time, the sealing tube and winding equipment arranged at the rear end further isolate the humid environment, ensuring the production quality of cross-linked polyethylene insulated cables from multiple links, reflecting the efficiency and practicality of the device in the production of cross-linked polyethylene insulated cables.

[0017] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0018] See also Figures 1-8 The present invention provides a twisting device for the production of cross-linked polyethylene insulated cables, including a support plate 32 and a twisting seat 31. An internal gear 34 is fixedly mounted on the support plate 32. A twisting drum 35 is provided on the support plate 32.

[0019] The cleaning mechanism includes a wire harness limiting cylinder 37, an annular cleaning brush 38 is provided on the inner wall of the wire harness limiting cylinder 37, a second gear 36 is fixedly mounted on the circumferential surface of the wire harness limiting cylinder 37, the second gear 36 is meshed with the inner wall of the inner gear 34, the inner wall opening of the wire harness limiting cylinder 37 is chamfered, and grease is coated on the rounded corners. When a single cable passes through the wire harness limiting cylinder 37 and the annular cleaning brush 38 inside it, it will not cause great wear to the cable, thereby effectively avoiding excessive wear of the single cable when twisted, and the wire harness limiting cylinder 37 is provided with a plurality of cleaning brushes. The annular cleaning brush 38 can effectively clean a single cable passing through, preventing some oil and impurities from destroying the integrity and uniformity of the cable insulation layer. A wire delivery shaft 33 is fixedly installed on the side end of the wire delivery shaft 33, and a plurality of single cable winding drums are provided on the side end of the wire delivery shaft 33. The winding drums and the like belong to the existing technology and can be rotated under the operation of the rotating shaft. When the wire winding drum 35 rotates, the cleaning mechanism inside it will rotate synchronously. At this time, the multiple second gears 36 engaged with the internal gear 34 will rotate synchronously, so that the annular cleaning brush 38 can rotate and clean the single cable.

[0020] In this embodiment, Figure 1 、 Figure 6 、 Figure 8 As shown, the gear mechanism includes a transmission rod 14, which is arranged on the coupling seat 31 through a bearing. The left end of the transmission rod 14 is fixedly mounted with a third gear 39, and the circumferential surface of the winding drum 35 is provided with a tooth groove. The third gear 39 is engaged with the tooth groove on the winding drum 35. The right end of the transmission rod 14 is fixedly mounted with a first gear 11, and the circumferential surface of the first gear 11 is engaged with a gear timing belt 12. When the winding drum 35 winds multiple single cables, it will rotate. At this time, the winding drum 35 will drive the third gear 39 to rotate, and the third gear 39 will drive the transmission rod 14 and the first gear 11 to rotate, so that the first gear 11 can drive the rotation and vibration mechanism to work through the gear timing belt 12.

[0021] In this embodiment, Figure 1 、 Figure 3 、 Figure 6 As shown, the rotational vibration mechanism includes two first support rods 15, the two first support rods 15 are fixedly mounted on the twisting seat 31, a first limiting ring 16 is fixedly mounted between the two first support rods 15, the inner wall of the first limiting ring 16 is mounted with a first rotating ring 13 through a bearing, the circumferential surface of the first rotating ring 13 is provided with a tooth groove, the inner wall of the gear timing belt 12 is engaged with the tooth groove on the first rotating ring 13, a connecting plate 18 is fixedly mounted between the two first support rods 15, four limiting bars 19 are fixedly mounted on the connecting plate 18, a collision rubber block 17 is fixedly mounted on the inner wall of the first rotating ring 13, when the twisted multi-core cable passes through the circular hole in the twisting seat 31, it will pass through the connecting plate 18 and the first rotating ring 13, at this time the first rotating ring 13 is rotating at the first gear 11 and the gear timing belt 12 The first rotating ring 13 rotates synchronously with the first rotating ring 13, and the collision rubber block 17 can drive the collision rubber block 17 to rotate. Since the collision rubber block 17 is elastic, when the collision rubber block 17 passes through a limit stop rod 19 and then separates from the limit stop rod 19, a rebound force will be generated. During the rebound process, it will hit the multi-core cable, thereby causing it to vibrate. The four limit stops 19 set on the connecting plate 18 can allow the collision rubber block 17 to cause multiple vibrations to the multi-core cable, and the first rotating ring 13 will continue to rotate, so that the multi-core cable can be subjected to a uniform circumferential force. This force can break the internal stress balance caused by factors such as uneven force on each strand and twisting order during the twisting process, redistribute the stress, and thus achieve the purpose of eliminating stress, effectively avoiding the local strength reduction caused by stress concentration.

[0022] In this embodiment, Figure 1 、 Figure 1 、 Figure 4 、 Figure 5As shown, the drying mechanism includes four L-shaped connecting frames 25, which are all fixedly mounted on the first rotating ring 13. The side ends of the four L-shaped connecting frames 25 are fixedly mounted with a second rotating ring 21. The circumferential surface of the second rotating ring 21 is mounted with a second limiting ring 28 through a bearing. Two second support rods 29 are fixedly mounted on the second limiting ring 28. The two second support rods 29 are respectively fixedly mounted on the two first support rods 15. At least eight water-absorbing sponge columns 22 are fixedly mounted on the second rotating ring 21. An adjustment plate 26 is fixedly mounted on the eight water-absorbing sponge columns 22. The adjustment plate 26 is rotatably mounted on the second rotating ring 21 through a bearing. The annular anti-static brush 2 7 is installed on the inner wall of the adjusting plate 26 and the second rotating ring 21 by bolts, the second fixing plate 24 is fixedly installed on the adjusting plate 26, and two first fixing plates 23 are fixedly installed on the second rotating ring 21. Positioning bolts are provided between the second fixing plate 24 and the first fixing plate 23. When the air humidity is low, the annular anti-static brush 27 can be installed on the inner wall of the adjusting plate 26 and the second rotating ring 21. Then, when the multi-core cable passes through the annular anti-static brush 27, the rotation of the annular anti-static brush 27 can eliminate the static electricity on its surface, avoiding static electricity from adsorbing tiny particles such as dust and dander in the air and causing them to adhere to the surface of the multi-core cable, thereby affecting the quality of the multi-core cable.

[0023] In this embodiment, Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 As shown, when the cable production is in a high humidity environment (relative humidity exceeds 70%), the multi-core cable is not affected by static electricity, but will be affected by air humidity. At this time, the bolts on the second fixing plate 24 and the first fixing plate 23 can be removed, and then the annular anti-static brush 27 can be removed from the adjustment plate 26 and the second rotating ring 21. The adjustment plate 26 is then rotated to align the second fixing plate 24 with the other first fixing plate 23, and then the bolts are installed. At this time, the adjustment plate 26 will drive the eight water-absorbing sponge columns 22 to twist and fix, so that the eight water-absorbing sponge columns 22 can contact the multi-core cable. When the multi-core cable passes through the eight water-absorbing sponge columns 22, it can absorb moisture on the surface of the multi-core cable, thereby avoiding excessive moisture on the surface of the multi-core cable, causing the insulation layer to become damp, the insulation resistance to decrease, and affecting the electrical performance and safety of the cable. A sealing tube is provided at the rear end of the drying mechanism. After exiting the sealing tube, a winding device for sealing the multi-core cable is provided, thereby preventing the multi-core cable from being affected by moisture.

[0024] Working principle: In the first step, a single cable is led out from the reel of the transmission shaft 33 and passes through the harness limiting cylinder 37 in the winding drum 35. When the winding drum 35 rotates, it drives the second gear 36 to engage with the internal gear 34, so that the harness limiting cylinder 37 rotates. The annular cleaning brush 38 on its inner wall rotates to clean the surface of the cable to remove oil and impurities. At the same time, the rounded corners and grease of the harness limiting cylinder 37 can reduce cable wear. In the second step, when the capstan 35 rotates, its circumferential tooth groove engages with the third gear 39, driving the transmission rod 14 to rotate. The first gear 11 on the right side of the transmission rod 14 transmits power to the first rotating ring 13 of the rotating vibration mechanism through the gear timing belt 12, realizing linkage. In the third step, the first rotating ring 13 rotates under the drive of the gear timing belt 12, and the collision rubber block 17 on the inner wall rotates with it. When the collision rubber block 17 passes through the limit stop rod 19 on the connecting plate 18, it collides and rebounds to hit the multi-core cable when separated. Through multiple vibrations, the stress balance inside the cable is broken and the stress is eliminated. Step 4: Anti-static (low humidity environment): The annular anti-static brush 27 is fixed to the adjustment plate 26 and the inner wall of the second rotating ring 21 by bolts. When the multi-core cable passes through, the anti-static brush rotating with the second rotating ring 21 eliminates static electricity on its surface to prevent the absorption of dust and affect the quality. Water absorption and drying (high humidity environment): Remove the bolts of the second fixing plate 24 and the first fixing plate 23, rotate the adjustment plate 26 to make the water-absorbing sponge column 22 contact the cable to absorb surface moisture, and then fix it with the other first fixing plate 23 with bolts. In the fifth step, the twisting drum 35 rotates as a power source, driving the cleaning, transmission, vibration and drying mechanisms in turn to realize the complete production process of the cable from cleaning and twisting to stress relief, drying and static removal. The sealing tube and winding equipment at the rear end of the drying mechanism further prevent the cable from getting damp, ensuring production quality.
