Description

Technical Field

[0001] The present invention relates to the technical field of cable winding, in particular to a flat flexible cable and a matching winding mechanism. Background Art

[0002] At present, in the fields of modern electrical equipment and industrial automation, flat flexible cables are widely used due to their advantages such as space saving and easy installation. However, there are many deficiencies in the existing flat cables. On the one hand, their structural design fails to fully consider the compressive and heat-resistant insulation performance. During actual use, the flat cables are prone to deformation due to external extrusion, affecting the stability of the internal circuits. At the same time, in the face of high-temperature environments, due to the lack of effective heat insulation measures, the cable insulation layer will age rapidly, shortening the service life. This poor heat resistance and compressive ability make it difficult for the existing flat cables to meet the requirements of reliability and safety under complex working conditions. On the other hand, the supporting winding devices also have defects. Currently, most winding devices lack effective guiding structures. During the winding operation, it is necessary to rely on manual pushing of the cable for guiding to achieve uniform winding. Without human intervention, the cable is extremely likely to be concentrated and wound around the middle of the winding roller, which will not only affect the winding efficiency, but also cause cable damage due to local stress concentration, reducing the cable quality and service performance, and further increasing the equipment maintenance cost. Therefore, whether it is the performance of the flat cable itself or its supporting winding device, technical innovation is urgently needed to solve the existing problems. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: First, in the present invention, the overall flat flexible cable has excellent comprehensive performance. Its wear-resistant outer layer is made of polyurethane material, which effectively resists external friction and extends the service life. The heat-resistant layer selects aerogel, which improves the stability in high-temperature environments by virtue of its low thermal conductivity. The polyvinyl chloride insulation layer ensures the safety of current transmission. The spring steel reinforcement steel ring between the heat-resistant layer and the wear-resistant outer layer takes into account both compressive strength and flexibility, making it easy to wind up and not easily deformed. The overall design meets the requirements of complex working conditions for protection, heat resistance, insulation and structural strength. Second, in the present invention, by setting up a guiding mechanism, the convenience of overall disassembly and assembly of the winding roller can be improved. During operation, rotate the adjusting handrail to drive the screw rod to rotate. The reverse threads at both ends drive the slider to slide on the guide rail, thereby driving the displacement of the support rod and the hexagonal clamping seat, realizing the clamping of the insertion block to fix the winding roller. Turning the self-locking bolt can further stabilize it. When disassembling, loosen the self-locking bolt and then rotate the adjusting handle. The screw rod drives the slider to move outwards, so that the hexagonal clamping seat releases the insertion block. This process does not require complex tools, reduces the maintenance time cost, and improves the convenience of equipment use; Third, in the present invention, the guiding mechanism of the device can improve the winding uniformity and stability during the cable winding process. During use, the driving motor can be started. After the driving motor operates, through the transmission of belt pulleys, connecting rods, bevel gears, etc., the semi-gear intermittently meshes with the rack inside the carriage, driving the carriage to slide back and forth on the top frame. The support strip ensures smooth sliding. The carriage drives the guiding rod and the guiding ring to move. After the cable passes through the guiding ring, uniform winding is achieved under its reciprocating sliding, avoiding concentrated winding of the cable. This design does not require manual intervention, improves the winding efficiency and quality, reduces the risk of cable damage, and enhances the winding performance of the equipment.

[0015] Third, in the present invention, through this special internal structure design of the guiding ring, when the cable is reciprocally swung by the guiding ring and guided to the winding roller, it can effectively maintain its flat posture, greatly suppressing the spiral winding phenomenon that is prone to occur during the tensile and bending processes of the flat cable. This precise control ensures that the cable can be wound neatly and smoothly on the winding roller along the predetermined path, solving the problems of chaotic winding, uneven interlayer stacking, and even cable damage that are prone to occur during the winding of flat cables.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 8, in the embodiment of the present invention, a flat flexible cable and a cooperating winding mechanism are provided, including a wear-resistant outer layer 1. A heat-resistant layer 2 is fixedly connected to the inner side of the wear-resistant outer layer 1. Insulating layers 3 are installed at equal intervals and linearly arranged on the inner side of the heat-resistant layer 2. Cable cores 4 are fixedly connected to the inner sides of the insulating layers 3. The wear-resistant outer layer 1 is a polyurethane outer layer, the heat-resistant layer 2 is an aerogel layer, and the insulating layer 3 is a polyvinyl chloride layer. Reinforcing steel rings 5 are fixedly connected at equal intervals and linearly between the inner sides of the heat-resistant layer 2 and the wear-resistant outer layer 1. The reinforcing steel rings 5 are made of spring steel. During the working process of this flat flexible cable, various structures cooperate to ensure performance. The wear-resistant outer layer 1 is made of polyurethane material. With its excellent wear resistance, it can resist external friction, scratching and other physical damages, effectively protecting the internal structure of the cable. The heat-resistant layer 2 is an aerogel layer. Aerogel has low thermal conductivity, which can effectively block heat transfer, prevent the cable from being damaged due to high-temperature environment or its own heat generation, and improve the stability of the cable under high-temperature working conditions. The equally spaced polyvinyl chloride insulating layers 3 inside isolate the cable cores 4 from each other, avoiding short circuits between the cores and ensuring the stable transmission of current in their respective cores. The reinforcing steel rings 5 are made of spring steel and have good elasticity and strength. On the one hand, they can provide structural support for the cable, preventing the cable from deforming or breaking under bending, stretching and other conditions. On the other hand, when the cable is wound, they can assist in maintaining the flat shape of the cable, enabling it to be orderly stored in the winding mechanism, while ensuring the mechanical properties of the cable in a complex environment, extending the service life of the cable, and meeting the usage requirements of various scenarios.

[0020] Please refer to Figures 3 - 8 , a flat flexible cable and a cooperating winding mechanism, including a base frame 6. A displacement adjusting mechanism 7 is fixedly installed in the middle of the base frame 6. A support rod 8 is fixedly installed at the top of the displacement adjusting mechanism 7. Hexagonal clamping seats 9 are rotatably connected to the inner sides of the support rods 8. Plug blocks 10 are inserted into the interiors of the hexagonal clamping seats 9. A winding roller 11 is fixedly installed on the inner sides of the plug blocks 10. A guiding mechanism 12 is fixedly installed on the outer side of one of the support rods 8. A tensioning mechanism 13 is fixedly installed on one side of the top of the base frame 6. When this winding mechanism operates, the displacement adjusting mechanism 7 is activated, which can quickly clamp and install the winding roller 11. The winding roller 11 is inserted and cooperated with the hexagonal clamping seat 9 through the plug block 10, realizing quick installation and disassembly, and facilitating the replacement of winding rollers 11 of different sizes. When the cable needs to be wound, one end of the cable is fixed on the winding roller 11, and the winding roller 11 is driven to rotate to drive the cable to wind. During this process, the guiding mechanism 12 plays a role in guiding and limiting the conveying path of the cable, ensuring that the cable can be neatly and orderly wound on the winding roller 11. The tensioning mechanism 13 monitors and adjusts the tension of the cable in real time, avoiding the cable from being slack or too tight during the winding process. Slack will cause the cable to wind messily, and being too tight may damage the cable. Through stable tension control, the winding quality is guaranteed, enabling the cable to be tightly and evenly wound on the winding roller 11, completing an efficient and reliable winding operation.

[0021] Please refer to Figures 4 - 8 Figure, the guiding mechanism 12 includes a support bracket 121 which is fixedly connected to the outside of a support rod 8. A driving component 122 is fixedly installed at the upper end of the support bracket 121. A linkage component 123 is fixedly connected to the inner side of the upper end of the support rod 8 with the support bracket 121. A guiding rod 124 is fixedly installed at the bottom of the linkage component 123. The lower end of the guiding rod 124 is fixedly connected to a guiding ring 125; Please refer to Figures 9 - 11 Figure, a hollow slideway 1251 is arranged inside the guiding ring 125. Two groups of arc-shaped sliders 1252 are slidably connected inside the hollow slideway 1251. Spring grooves 1253 are formed on the sides of the two groups of arc-shaped sliders 1252 close to each other. A fixing seat 1254 is slidably inserted into the spring groove 1253. A tension spring 1255 is connected between the fixing seat 1254 and the spring groove 1253. The fixing seat 1254 is arranged in a U shape, and a roller 1256 is installed in the U-shaped groove of the fixing seat 1254. The two groups of rollers 1256 are arranged oppositely for the cable to pass through; Two limiting blocks 1257 are symmetrically arranged inside the hollow slideway 1251. Arc-shaped springs 1258 are installed on both sides of the limiting blocks 1257. The other ends of the arc-shaped springs 1258 abut against the sides of the arc-shaped sliders 1252 to limit the arc-shaped sliders 1252 and keep the arc-shaped sliders 1252 at the middle position as much as possible.

[0022] In order to enable the roller 1256 to apply an appropriate clamping force to the cable, the tension spring 1255 generates an outward pulling force to pull the fixing seat 1254 and the roller 1256 thereon out of the spring groove 1253, so that the two opposite rollers 1256 move towards each other, generating an elastic clamping effect on the passing cable.

[0023] The elastic restoring force of the arc-shaped spring 1258 is used to limit the movement range of the arc-shaped slider 1252. Through their combined action, the two groups of arc-shaped sliders 1252 and the roller assemblies thereon are kept at the central area inside the guiding ring 125 as much as possible, ensuring the centering of the cable channel. At the same time, the arc-shaped spring 1258 also provides a certain elastic buffer, allowing the arc-shaped slider 1252 to make fine adjustment movements when the cable width changes slightly.

[0024] Through this special internal structure design of the guiding ring 125, when the cable is reciprocally swung by the guiding ring 125 and guided to the winding roller 11, the cable can effectively maintain its flat posture, greatly suppressing the spiral winding phenomenon that is prone to occur during the tension and bending of the flat cable. This precise control ensures that the cable can be wound neatly and smoothly on the winding roller 11 according to the predetermined path, solving the problems of chaotic winding, uneven interlayer stacking and even cable damage that are prone to occur during the winding of the flat cable.

[0025] The driving assembly 122 includes an installation sleeve 1221 and a fixing rod 1222. The installation sleeve 1221 is fixedly connected to the top of the support bracket 121. A driving motor 1223 is fixedly connected inside the installation sleeve 1221. The output end of the driving motor 1223 penetrates through the installation sleeve 1221 and is fixedly connected to a first belt pulley 1224. The fixing rod 1222 is fixedly connected to the top of the hexagonal card seat 9. The linkage assembly 123 is fixedly connected to the top of the fixing rod 1222. The first belt pulley 1224 and the fixing rod 1222 are in transmission connection. The linkage assembly 123 includes a top frame 1231. The top frame 1231 is fixedly connected to the top of the fixing rod 1222. A second belt pulley 1232 is rotatably connected to the upper end of the side of the top frame 1231 close to the driving motor 1223. The second belt pulley 1232 is in transmission connection with the first belt pulley 1224 through a transmission belt. A connecting rod 1233 is rotatably connected to the side of the top frame 1231 away from the driving motor 1223. The outer end of the connecting rod 1233 is fixedly connected to the second belt pulley 1232. A transmission group 1234 is provided at the end of the connecting rod 1233. A guiding rod 124 is fixedly connected to one side of the transmission group 1234. The transmission group 1234 includes an upper bevel gear 12341, a lower bevel gear 12342, and a sliding frame 12343. The sliding frame 12343 is slidably connected to the bottom of the top frame 1231. The upper bevel gear 12341 is fixedly connected to the end of the connecting rod 1233 away from the second belt pulley 1232. The lower bevel gear 12342 is rotatably connected to the end of the top of the top frame 1231 away from the driving motor 1223. The upper bevel gear 12341 and the lower bevel gear 12342 are meshed. A half gear 12344 is fixedly connected to the bottom of the lower bevel gear 12342. Rack bars 12345 are fixedly connected to both sides inside the sliding frame 12343. The rack bars 12345 and the half gear 12344 are meshed. The guiding rod 124 is fixedly connected to the middle of one side of the sliding frame 12343. A support rail 12346 is fixedly installed on the top of the top frame 1231. A support bar 12347 is slidably connected inside the support rail 12346. The bottom of the support bar 12347 is connected to the outer end of the top of the sliding frame 12343. During use, when the winding mechanism operates, the driving motor 1223 in the guiding mechanism 12 starts, driving the first belt pulley 1224 inside the installation sleeve 1221 to rotate. The first belt pulley 1224 is in transmission connection with the second belt pulley 1232 through a transmission belt, thereby transmitting power to the second belt pulley 1232 and causing the second belt pulley 1232 to start rotating. The second belt pulley 1232 is fixedly connected to the connecting rod 1233. Therefore, the connecting rod 1233 rotates synchronously with the second belt pulley 1232. The upper bevel gear 12341 at the end of the connecting rod 1233 also rotates accordingly and meshes with the lower bevel gear 12342, transmitting the rotational motion to the lower bevel gear 12342. During the rotation of the half gear 12344 fixedly connected to the bottom of the lower bevel gear 12342, it alternately meshes with the rack bars 12345 on both sides of the sliding frame 12343. When the half gear 12344 meshes with one side of the rack bar 12345, it pushes the sliding frame 12343 to slide along the bottom of the top frame 1231,At this time, the other rack 12345 disengages from the half gear 12344; as the half gear 12344 continues to rotate, it engages with the other rack 12345 and pushes the carriage 12343 to slide in the opposite direction, thus realizing the reciprocating linear motion of the carriage 12343. The guide rod 124 fixedly connected to the middle of the carriage 12343 and the guide ring 125 at the lower end also move synchronously with the carriage 12343 to guide the conveying direction of the cable. At the same time, the support rail 12346 and the support strip 12347 on the top of the top frame 1231 cooperate to provide stable guidance and support for the sliding of the carriage 12343, ensuring the smooth movement of the guide rod 124 and the guide ring 125, so that the cable can be neatly wound around the winding roller 11 along the predetermined path during the winding process, avoiding problems such as cable stacking and chaotic winding.

[0026] Please refer to Figures 2 - 4 As shown in the figure, the adjustment mechanism 7 includes a guide rail 71. The guide rail 71 is fixedly installed in the middle of the top of the base frame 6. A lead screw 72 is rotatably connected inside the guide rail 71. The thread directions at both ends of the lead screw 72 are opposite. Sliders 73 are threadedly connected to both ends of the outer surface of the lead screw 72. A support rod 8 is fixedly connected to the top of the slider 73. The end of the lead screw 72 penetrates through the guide rail 71 and is fixedly connected with an adjustment handle 74. A self-locking bolt 75 is threadedly connected to the adjustment handle 74. The end of the self-locking bolt 75 penetrates through the adjustment handle 74. The self-locking bolt 75 is set as a hand-tightening bolt. During use, when it is necessary to adjust the position of the winding roller 11, the operator rotates the adjustment handle 74 in the adjustment mechanism 7 to drive the lead screw 72 to rotate inside the guide rail 71. Since the thread directions at both ends of the lead screw 72 are opposite, when the lead screw 72 rotates, the sliders 73 at both ends of its outer surface will move synchronously in opposite directions along the guide rail 71 according to the principle of screw drive. The support rod 8 fixedly connected to the top of the slider 73 also moves accordingly, thereby driving the hexagonal clamping seat 9, the insertion block 10 and the winding roller 11 rotatably connected inside the support rod 8 to adjust their positions to adapt to the winding requirements of cables of different widths or specifications. When the winding roller 11 is adjusted to the appropriate position, the operator can turn the hand-tightening self-locking bolt 75 so that its end penetrates through the adjustment handle 74 and abuts against the surface of the guide rail 71, and fixes the adjustment handle 74 by increasing the friction force, thereby locking the position of the lead screw 72 to prevent the lead screw 72 from rotating due to external force during the winding process, ensuring that the slider 73, the support rod 8 and the winding roller 11 remain fixed, and guaranteeing the stability and accuracy of the cable winding operation.

[0027] Please refer to Figure 7, the tensioning mechanism 13 includes a mounting frame 131. The mounting frame 131 is fixedly installed at one end of the base frame 6 close to the guide rod 124. A regulating screw 132 is threadedly connected to the middle of the mounting frame 131. The regulating screw 132 is set as a hand-tightening screw. The top of the regulating screw 132 is rotatably connected to a top plate 133. Tensioning springs 134 are fixedly connected to the top of the top plate 133 at equal intervals in a linear arrangement. The top of the tensioning spring 134 is fixedly installed with a concave seat 135. A tensioning roller 136 is rotatably connected inside the concave seat 135. Fixed support rods 137 are fixedly installed on both sides of the bottom of the concave seat 135. The bottom of the fixed support rod 137 penetrates through the top plate 133 and the mounting frame 131. The fixed support rod 137 is slidably connected to the top plate 133 and the mounting frame 131. By setting the tensioning mechanism 13, during use, the regulating screw 132 can be rotated by twisting. When the regulating screw 132 rotates, it can assist in driving the top plate 133 to move upward. When the top plate 133 moves upward, it can drive the concave seat 135 to move upward. When the concave seat 135 moves upward, it can drive the tensioning roller 136 thereon to extrude the cable to be wound. At this time, the elastic expansion and contraction of the tensioning spring 134 is used to further improve the tensioning effect. And by setting the fixed support rod 137, it can support and guide the concave seat 135 and the top plate 133, and can improve the overall tensioning effect; during the cable winding process of this device, when it is necessary to adjust the cable tension, the operator manually rotates the hand-tightening regulating screw 132 in the tensioning mechanism 13. Since the regulating screw 132 is threadedly connected to the middle of the mounting frame 131, as the screw rotates, under the action of screw drive, the screw moves upward, driving the top plate 133 rotatably connected thereto to move upward synchronously. After the top plate 133 moves upward, the concave seat 135 is pulled to rise through the connected tensioning spring 134. The tensioning roller 136 rotatably connected inside the concave seat 135 moves upward accordingly, gradually contacts the cable and exerts an extrusion effect on it, thereby adjusting the tension degree of the cable. During this process, the tensioning spring 134 can elastically expand and contract according to the actual force on the cable, adaptively compensating and adjusting the tension force, further enhancing the tensioning effect, ensuring that the cable always maintains a proper tension state during winding. At the same time, the fixed support rods 137 on both sides of the bottom of the concave seat 135 penetrate through the top plate 133 and the mounting frame 131 and are slidably connected thereto. During the up and down movement of the concave seat 135 and the top plate 133, the fixed support rods 137 play a guiding and supporting role, restricting their moving directions, preventing deviation or inclination, ensuring that the tensioning roller 136 can stably and vertically apply pressure to the cable, thereby improving the stability and reliability of the entire tensioning mechanism 13 working and guaranteeing the cable winding quality.

[0028] The working principle of the present invention is as follows: During application, the overall flat flexible cable can have strong wear resistance and heat resistance. Its wear-resistant outer layer 1 is made of polyurethane material, endowing the cable with excellent wear resistance, effectively resisting external friction and abrasion, and extending the service life; the heat-resistant layer 2 is selected as an aerogel layer. With its extremely low thermal conductivity, it can efficiently block heat transfer, significantly improving the stability of the cable in high-temperature environments and protecting the internal structure; the polyvinyl chloride insulation layer 3 provides reliable electrical insulation performance, ensuring the safe and stable transmission of current. In addition, the spring steel reinforcement steel ring 5 arranged between the heat-resistant layer 2 and the wear-resistant outer layer 1 maintains the flexibility of the cable by utilizing the good elasticity and toughness of the spring steel while ensuring the compressive strength of the cable, making it easy to wind up and not easily deformed. The overall design takes into account protection, heat resistance, insulation, and structural strength, meeting the requirements of various complex working conditions. The guiding mechanism 12 provided by the present invention provides an efficient and stable solution for the installation and disassembly of the winding roller 11. During actual operation, by rotating the adjustment handrail, the lead screw 72 is driven to rotate. The lead screw 72 is arranged inside the guide rail 71, and its two ends are designed with opposite thread directions. This special thread structure enables the lead screw 72 to drive the slider 73 to slide inside the guide rail 71 when rotating. As the slider 73 reciprocates, the connecting rod 8 also moves accordingly, thereby driving the hexagonal clamping seat 9 to displace. When the hexagonal clamping seat 9 moves inward, it can quickly clamp the plug 10, thus completing the auxiliary installation and fixation of the winding roller 11. After the winding roller 11 is installed, the adjustment handle 74 is fixed by turning the self-locking bolt 75 to further ensure the stability of the installation of the winding roller 11. When disassembling the winding roller 11, the operation process is equally simple. Just loosen the self-locking bolt 75 to make it move outward, and then the adjustment handle 74 can be rotated again. The rotation of the adjustment handle 74 drives the lead screw 72 to drive the slider 73 to move outward. The outward movement of the slider 73 drives the connecting rod 8 to move outward synchronously, thereby causing the hexagonal clamping seat 9 to move outward, prompting the plug 10 to disengage from the inside of the hexagonal clamping seat 9, and finally realizing the quick disassembly of the winding roller 11. The design of this guiding mechanism 12 makes the disassembly and assembly process of the winding roller 11 not require complex tools and cumbersome operations, effectively improving the convenience of equipment use and reducing the time cost required for equipment maintenance and replacement of the winding roller 11. The guiding mechanism 12 of the present invention plays an important role in the process of cable winding, achieving automatic and uniform winding of the cable. When the device operates, the driving motor 1223 starts, driving the first pulley 1224 to rotate. The first pulley 1224 transmits power to the second pulley 1232 through the transmission belt, prompting the second pulley 1232 to rotate. The rotation of the second pulley 1232 drives the connecting rod 1233, the upper bevel gear 12341, the lower bevel gear 12342, and the half gear 12344 to rotate in sequence. Among them, the cooperation between the half gear 12344 and the rack 12345 is the key to achieving uniform winding of the cable; During the rotation of the half gear 12344, it first meshes with a rack 12345 inside the carriage 12343, driving the carriage 12343 to slide to one side. When the half gear 12344 rotates half a turn, it meshes with another rack 12345, and then drives the carriage 12343 to slide to the other side. This design realizes the intermittent meshing transmission between the half gear 12344 and the two racks 12345 through the coordinated action of the linkage assembly 123 and the transmission group 1234, thereby driving the carriage 12343 to slide reciprocally on the top frame 1231. During the sliding process of the carriage 12343, the support bars 12347 inside the support rail 12346 provide support for the carriage 12343, ensuring the smoothness and reliability of its sliding; The reciprocating sliding of the carriage 12343 drives the guide rod 124 and the guide ring 125 to move synchronously. During the cable winding process, the cable is threaded into the inside of the guide ring 125. As the driving motor 1223 continues to operate, the guide ring 125 slides reciprocally driven by the carriage 12343, thereby driving the cable being wound to swing reciprocally. This reciprocating swing enables the cable to be evenly wound around the outer surface of the winding roller 11, avoiding the problem that the cable is concentratedly wound in the middle of the winding roller 11. The design of this guiding mechanism 12 can achieve automatic and uniform winding of the cable without manual intervention, not only improving the winding efficiency, but also ensuring the winding quality, reducing the risks of cable damage and equipment failure caused by uneven cable winding, and significantly enhancing the overall winding convenience and uniformity of the equipment.
