Description

Technical Field

[0001] This invention belongs to the field of cable insulation tape production, specifically a tape conveying device for cable insulation tape production lines. Background Technology

[0002] Insulating materials are not absolutely non-conductive; they only exhibit "insulation" under rated operating voltage. During cable manufacturing, such materials must be wrapped around the conductor surface to form a continuous and uniform insulation layer, preventing electrical breakdown and resisting mechanical damage. Before the slit tape is sent to the wrapping station, the production line makes it swing horizontally back and forth while applying controllable tension to the tape surface. This process of conveying and stretching simultaneously can immediately smooth out potential creases, frilly edges, and micro-bubbles in the adhesive layer, preventing subsequent wrinkling and overlapping. This allows defects to be exposed and eliminated online in advance, significantly improving the consistency and electrical reliability of the finished insulation tape.

[0003] A patent document with announcement number CN217971873U discloses a conveyor device for an insulating material tape production line, including a base, a support assembly fixedly connected to the top surface of the base, two sets of support rods fixedly connected to the top surface of the base, a fixed seat fixedly connected to the top of each set of support rods, a first threaded screw rotatably connected to the inner wall of the fixed seat, a first bevel gear fixedly connected to one end of the first threaded screw, and a second bevel gear rotatably connected to the surface of the fixed seat.

[0004] In traditional technical solutions, cable insulation tape, similar to mica tape, requires a horizontal displacement transmission structure to stretch and extend it during transmission to improve processing quality. Traditional solutions use screws or telescopic cylinders for drive. This method results in jerky displacement and abrupt tension changes, leading to a stiff stretching curve that is not conducive to smooth stretching of the insulation tape. Furthermore, the movement of the transmission structure in traditional structures is usually uniform, but creases, frayed edges, and microbubbles in the adhesive layer are deeply embedded inside the tape. The initial stretching only loosens the reinforcing material, while the subsequent tension surges, causing the tape to tear open and flatten. Therefore, effective stretching almost entirely occurs at the end of the stroke.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1: As Figures 1-6 As shown, the cable insulation tape production line conveying device of the present invention includes a conveyor frame 1, a fixed frame 15 and a limiting wheel 16 installed on the side of the conveyor frame 1, a swing mechanism 2 slidably installed on the fixed frame 15, and the limiting wheel 16 rotatably installed on the side of the conveyor frame 1, and its horizontal height is higher than that of the fixed frame 15. The cable insulation tape is conveyed to the swing mechanism 2 via the conveyor frame 1 and the limiting wheel 16 and then conveyed to the back. The horizontal displacement of the swing mechanism 2 stretches and expands the cable insulation tape. A hollow cavity 25 is opened through the inside of the swing mechanism 2. An air-floating moving platform 3 is fixedly installed inside the hollow cavity 25. A groove is opened inside the fixed frame 15. The air-floating moving platform 3 slides inside the groove of the fixed frame 15 and drives the swing mechanism 2 to move horizontally.

[0033] An air-bearing guide column 4 is installed inside the slot of the fixed frame 15. The air-bearing moving platform 3 is horizontally displaced through the air-bearing guide column 4. An air-supplying tension member 5 is installed at one end of the slot of the fixed frame 15, and a spring-reset member 6 is installed at the other end of the slot of the fixed frame 15. The opposing ends of the air-supplying tension member 5 and the spring-reset member 6 are connected to the two sides of the air-bearing moving platform 3. The air-supplying tension member 5 is inflated and pulls the air-bearing moving platform 3 and the swing mechanism 2 to move away from the limit wheel 16. The spring coefficient generated by the stretching of the spring-reset member 6 drives the air-bearing moving platform 3 and the swing mechanism 2 to move closer to the limit wheel 16.

[0034] Specifically, the cable insulation material strip is sequentially conveyed to the limiting wheel 16 and the swing mechanism 2 via the conveyor frame 1. It then continues to be conveyed to the next step via the swing mechanism 2. During this process, the conveyor frame 1 can simultaneously convey and process the insulation strip. The air-bearing moving platform 3 is driven to move inside the fixed frame 15, thereby causing the swing mechanism 2 to move horizontally outside the fixed frame 15. At this time, the swing mechanism 2 moves from near the limiting wheel 16 towards away from it. During this process, the cable conveyor strip transmitted on the limiting wheel 16 and the swing mechanism 2 is stretched and extended. In conventional technology, the air-bearing moving platform 3 is typically driven by a screw or electric cylinder to move inside the fixed frame 15, thereby causing the swing mechanism 2 to move horizontally outside the fixed frame 15. Horizontal movement in this driving method results in jerky displacement of the transmission structure and abrupt tension changes, leading to a stiff stretching curve that is not conducive to the smooth stretching and unfolding of the insulating tape. In this device, the air-bearing moving platform 3 moves guided by two air-bearing guide columns 4, allowing the swing mechanism 2 to move smoothly outside the fixed frame 15, avoiding jerky displacement, abrupt tension changes, and a stiff stretching curve. In this device, the initial position of the swing mechanism 2 is relatively close to the limiting wheel 16. When the swing mechanism 2 moves away from the limiting wheel 16, it stretches and unfolds the insulating tape during transmission. In traditional technical solutions, the movement of the swing mechanism 2 is uniform, but creases, frayed edges, and microbubbles in the adhesive layer are deeply embedded inside the tape body. The initial stretching only loosens the reinforcing material, and the subsequent stretching... The movement of the swing mechanism 2 is necessary for effective stretching. In this device, when the swing mechanism 2 needs to move horizontally to stretch the insulating strip, the swing mechanism 2 is in the initial position near the limit wheel 16. At this time, the spring return member 6, which is in the position near the limit wheel 16 and on one side of the air-float moving platform 3, is in a state of no elastic deformation. When the air supply equipment uniformly supplies air into the air-supplying tension member 5, the air-supplying tension member 5 is preferably a structure of air-supply contraction. This causes the air-supplying tension member 5 to contract as a whole, thereby pulling the air-float moving platform 3 and the swing mechanism 2 to move away from the limit wheel 16, stretching the insulating strip during transmission. Because the spring return member 6 is a structure similar to a spring, the required tension for the initial stretching of the spring return member 6 is relatively small. In the first half, the air-supplying tension member 5 uniformly introduces air and pulls the air-float moving platform 3, which is faster than the original structural design. In the second half, the air-supplying tension member 5 continues to uniformly introduce air and pull the air-float moving platform 3 to stretch the insulating tape. However, at this time, the spring return member 6 is further stretched, and the elastic deformation of the spring return member 6 increases, which in turn compresses the gas inside the air-supplying tension member 5. This reduces the speed at which the air-supplying tension member 5 pulls the air-float moving platform 3 under uniform air intake compared to the traditional method. The uniform movement of the air-float moving platform 3 in the original technical solution is changed to a movement mode of fast at first and slow at the end. After quickly completing the first half of the stretching process, the second half of the stretching is applied to the creases, frills, and microbubbles of the adhesive layer deeply embedded in the tape body.Furthermore, the slow stretching and unfolding in the latter half of the process can resolve internal creases, frayed edges, and microbubbles in the adhesive layer of the tape, resulting in a more even application. Compared to traditional transmission and unfolding methods, it does not reduce the transmission rate of the insulating tape. Subsequently, an external air supply device draws gas from the internal air-carrying tension component 5, and under the restoring force of the elastic deformation of the spring return component 6, the swing mechanism 2 returns to its initial position for horizontal reciprocating movement, continuously performing the work of stretching and unfolding the insulating tape while it is being transmitted.

[0035] like Figures 1-3 As shown, a fixed platform 11 is installed above the conveyor frame 1. A conveyor guide roller 12 is movably installed on one side of the fixed platform 11. Multiple conveyor shafts 14 are installed above the fixed platform 11. A conveyor wheel 13 is movably installed on the side of the conveyor frame 1. The corresponding cable insulation tape is transmitted to the outside of the conveyor wheel 13 via the conveyor guide roller 12 and the corresponding conveyor shaft 14. The conveyor wheel 13 transmits the corresponding cable insulation tape to the limit wheel 16.

[0036] Multiple conveyor frames 1 and swing mechanisms 2 are arranged in sequence, and multiple cable insulation strips are transmitted one by one inside the corresponding conveyor frame 1.

[0037] A swing wheel 21 and a guide shaft 24 are movably mounted on one side of the swing mechanism 2. A fixed bracket 23 is fixedly mounted on the top of the swing mechanism 2. A discharge wheel 22 is movably mounted on one side of the fixed bracket 23. The cable insulation tape is sequentially transmitted to the swing wheel 21, the guide shaft 24 and the discharge wheel 22 via the limit wheel 16. The discharge wheel 22 is used to transmit the cable insulation tape to the next step.

[0038] Specifically, a set of cable insulation tapes is conveyed by the conveyor guide roller 12, conveyor shaft 14, conveyor wheel 13, limit wheel 16, swing wheel 21, and swing mechanism 2, and then transferred to the next step by the discharge wheel 22. During this transfer process, the stretching and expansion of this set of insulation tapes is completed. Multiple conveyor frames 1 and swing mechanisms 2 are set in sequence. Multiple insulation tapes conveyed by the same conveyor guide roller 12 are each conveyed to the corresponding conveyor frame 1 and swing mechanism 2 for transfer, thereby efficiently and simultaneously completing the conveying and stretching of multiple cable insulation tapes.

[0039] like Figures 4-6 As shown, a displacement groove 151 is provided inside the fixed frame 15. The air-floating moving platform 3 moves inside the displacement groove 151, which drives the swing mechanism 2 to move outside the fixed frame 15.

[0040] The displacement groove 151 includes a sliding inner cavity 1512 formed inside the fixed frame 15 and sliding grooves 1511 formed on both sides of the sliding inner cavity 1512. The air flotation moving platform 3 is slidably installed inside the sliding inner cavity 1512 and the two sliding grooves 1511.

[0041] Mounting block 152 and mounting block 253 are fixedly installed at both ends of the sliding inner cavity 1512, and the air flotation moving platform 3 is located between mounting block 152 and mounting block 253.

[0042] like Figures 7-8 As shown, the gas supply tension component 5 includes a fixed cylinder 51 fixedly installed inside the mounting block 152 and a tension rod 52 movably installed inside the fixed cylinder 51. One end of the tension rod 52 is fixedly connected to the side of the air flotation moving platform 3. An L-shaped gas supply pipe 53 is fixedly installed on one side of the fixed cylinder 51. The L-shaped gas supply pipe 53 is connected to the gas supply equipment inside the fixed frame 15.

[0043] The fixed cylinder 51 has an inner cylinder groove 511 and a limiting groove 512 inside, and the inner cylinder groove 511 and the limiting groove 512 are connected. A piston 521 is fixedly installed at one end of the tension rod 52 inside the fixed cylinder 51. The diameter of the piston 521 matches the inner diameter of the inner cylinder groove 511, and the diameter of the piston 521 is larger than the diameter of the limiting groove 512. The diameter of the tension rod 52 matches the diameter of the limiting groove 512.

[0044] Specifically, in the initial state, when the swing mechanism 2 is not stretched, the piston 521 is inside the inner cylinder groove 511 and there is a certain distance between it and the limiting groove 512. At this time, there is a certain amount of gas in the gap between the piston 521 and the limiting groove 512. When it is necessary to pull the swing mechanism 2 from the initial position near the limiting wheel 16 to the direction away from the limiting wheel 16, gas will be uniformly supplied into the L-shaped gas pipe 53 through the external gas supply device. That is, the gas in the gap between the piston 521 and the limiting groove 512 increases, thereby pushing the piston 521 to move into the inner cylinder groove 511. That is, the tension rod 52 will pull the air-floating moving platform 3 and the swing mechanism 511. As the oscillating mechanism 2 moves away from the limiting wheel 16, it stretches and extends the insulating tape. For the initial stretching of the spring return member 6, the required pulling force is relatively small. Therefore, initially, the piston 521 moves relatively quickly into the inner cylinder groove 511. After moving a certain distance quickly, i.e., completing the first half of the stretching, the greater the deformation of the spring return member 6, the more the gas in the gap between the piston 521 and the limiting groove 512 is compressed under uniform air intake. This slows down the movement of the piston 521 inside the inner cylinder groove 511. At this point, the moving speed of the oscillating mechanism 2 as it moves away from the limiting wheel 16 is also slowed down, thus entering the stretching phase for the insulating tape. In the latter half of the insulation strip stretching process, by planning the stretching time, compared to traditional techniques, the useless first half is quickly skipped, and the time is devoted to the stretching and unfolding process in the second half. The overall stretching time is almost the same as that of traditional techniques, but the stretching and unfolding effect is stronger and the potential damage to the insulation strip is reduced. When the swing mechanism 2 needs to return to the initial position for the next stretching of the insulation strip, air is drawn into the gap between the piston 521 and the limiting groove 512 through the external air supply equipment and the L-shaped air pipe 53. The air in the gap is not quickly drawn away, but is instead used to deform the force of the spring return component 6. The counterforce prevents the swing mechanism 2 from moving too quickly when it returns to its initial position, thus allowing the insulating tape to disengage from the transmission of the swing mechanism 2. Under the restoring force of the spring return member 6, the swing mechanism 2 moves towards the limit wheel 16. At this time, the piston 521 is driven to move towards the limit groove 512. When the swing mechanism 2 returns to its initial position, there is still a certain amount of gas in the gap between the piston 521 and the limit groove 512 that is not sucked out. This gas is compressed by the spring return member 6 at this time. This gas acts as a damping effect, so that the final movement of the swing mechanism 2 to return to its initial position will not be jerky, thereby reducing damage to the insulating tape.

[0045] Example 2: Figure 9As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the spring reset component 6 includes a connecting round block 61 fixedly installed on one side of the air-floating moving platform 3 and a spiral column 62 fixedly installed on one side of the connecting round block 61. The spring reset component 6 also includes a rotating column 63 rotatably installed inside the mounting block 2 153 via a bearing and a spring reset member 64 fixedly installed inside the mounting block 2 153. A limit ring 631 is fixedly installed on the outer side of the rotating column 63. The limit ring 631 passes through the spring reset member 64 and is connected to the spring spring inside the spring reset member 64. The rotating column 63 actively rotates to compress the spring spring inside the spring reset member 64. One end of the spiral column 62 is threadedly connected to the inside of the rotating column 63.

[0046] Specifically, when the air-bearing moving platform 3 moves away from the mounting block 153, it drives the spiral column 62 to move inside the rotating column 63, thereby causing the rotating column 63 and the limiting ring 631 to rotate inside the mounting block 153. At this time, the active rotation of the limiting ring 631 will compress the spring inside the spring reset piece 64, thus forming elastic deformation. When the rotating column 63 initially rotates, the elastic deformation of the spring is small, and the rotation of the rotating column 63 is relatively easy. That is, the air-bearing moving platform 3 drives the spiral column 62 away from the mounting block 153 relatively easily, quickly skipping the first half of the stretching process of the insulating tape. As the rotating column 63 continues to rotate, the elastic deformation of the spring increases, making the force required for the rotation of the rotating column 63 gradually increase. That is, the air-bearing moving platform 3 drives the spiral column 62 to continue moving away from the mounting block 153. The difficulty of dynamic deformation allows the focus of stretching to be shifted to the latter half of the insulation tape stretching process, effectively increasing the quality of insulation tape production. In this device, the deformation of a clockwork spring replaces a simple tension spring, reducing the footprint of the elastic structure. Moreover, in terms of the steepness of the tension increase from small to large, the clockwork spring is naturally better than a linear tension spring. Simply put, compared to the tension deformation of a traditional spring, the clockwork spring requires less tension from the air-supplying tension member 5 to begin elastic deformation, while the traditional spring requires more tension from the air-supplying tension member 5 to begin elastic deformation. However, the final elastic deformation tension of the two is almost the same. Therefore, in this device, the clockwork spring can further refine the initial fast-then-slow stretching time planning of the insulation tape, further improving the quality of insulation tape production.

[0047] Working principle: The cable insulation material strip is sequentially conveyed to the limit wheel 16 and the swing mechanism 2 via the conveyor frame 1. It then continues to be conveyed to the next step via the swing mechanism 2. During this process, the conveyor frame 1 can simultaneously convey and process the insulation strip. The air-bearing moving platform 3 is driven to move inside the fixed frame 15, thereby causing the swing mechanism 2 to move horizontally outside the fixed frame 15. At this time, the swing mechanism 2 moves from near the limit wheel 16 to away from it. During this process, the cable conveyor strip on the limit wheel 16 and the swing mechanism 2 is stretched and extended. In traditional technology, the air-bearing moving platform 3 is typically driven by a screw or electric cylinder to move inside the fixed frame 15, thereby causing the swing mechanism 2 to move horizontally outside the fixed frame 15. The horizontal movement of the side-mounted mechanism results in abrupt displacement and tension changes, leading to a stiff stretching curve that hinders smooth stretching of the insulating tape. In this device, the air-bearing moving platform 3 moves guided by two air-bearing guide columns 4, allowing the swing mechanism 2 to move smoothly outside the fixed frame 15, avoiding displacement abruptness, tension changes, and a stiff stretching curve. In this device, the initial position of the swing mechanism 2 is close to the limiting wheel 16. As the swing mechanism 2 moves away from the limiting wheel 16, it stretches the insulating tape during transmission. In traditional solutions, the movement of the swing mechanism 2 is uniform, but creases, frayed edges, and microbubbles in the adhesive layer are deeply embedded within the tape body. The initial stretching only loosens the reinforcing material, and the subsequent... The movement of the half-stroke swing mechanism 2 is necessary for effective stretching. In this device, when the swing mechanism 2 needs to move horizontally to stretch the insulating strip, the swing mechanism 2 is in the initial position near the limit wheel 16. At this time, the spring return member 6, which is in the position near the limit wheel 16 and on the side of the air-float moving platform 3, is in a state of no elastic deformation. When the air supply equipment uniformly supplies air into the air-supplying tension member 5, the air-supplying tension member 5 is preferably a structure of air-supply contraction, which will cause the air-supplying tension member 5 to contract as a whole, thereby pulling the air-float moving platform 3 and the swing mechanism 2 to move away from the limit wheel 16, stretching the insulating strip during transmission. Because the spring return member 6 is a structure similar to a spring, the required tension for the initial stretching of the spring return member 6 is relatively small. In the first half of the process, the air-supplying tension member 5 uniformly feeds air and pulls the air-float moving platform 3 relatively quickly compared to the original structural design. In the second half, the air-supplying tension member 5 continues to uniformly feed air and pull the air-float moving platform 3 to stretch the insulating tape. However, at this time, the spring return member 6 is further stretched, and the elastic deformation of the spring return member 6 increases, which in turn compresses the gas inside the air-supplying tension member 5. This reduces the speed at which the air-supplying tension member 5 pulls the air-float moving platform 3 under uniform air intake conditions compared to the traditional method. The uniform movement of the air-float moving platform 3 in the original technical solution is changed to a movement mode that is fast at first and then slow. After quickly completing the first half of the stretching process, the second half of the stretching is applied to the creases, frills, and microbubbles deeply embedded inside the tape body.Furthermore, the slow stretching and unfolding in the latter half can resolve creases, frilly edges, and microbubbles in the adhesive layer within the tape, resulting in a more even application. Compared to traditional transmission and unfolding methods, it does not reduce the transmission rate of the insulation tape. Subsequently, the gas inside the air-supplying tension component 5 is drawn in by an external air supply device, and under the restoring force of the elastic deformation of the spring return component 6, the swing mechanism 2 returns to its initial position for horizontal reciprocating movement, continuously performing the work of stretching and unfolding the insulation tape while transmitting it. When the air-floating moving platform 3 moves away from the mounting block 2 153... At this time, the spiral column 62 will move inside the rotating column 63, thereby causing the rotating column 63 and the limiting ring 631 to rotate inside the mounting block 153. At this time, the active rotation of the limiting ring 631 will compress the spring inside the spring reset piece 64, thus forming elastic deformation. When the rotating column 63 initially rotates, the elastic deformation of the spring is small, and the rotation of the rotating column 63 is relatively easy. That is, the air-bearing moving platform 3 can easily move the spiral column 62 away from the mounting block 153, quickly passing the first half of the stretching of the insulating tape. During the process, as the rotating column 63 continues to rotate, the elastic deformation of the spring increases, making the force required for the rotation of the rotating column 63 gradually increase. This makes it more difficult for the air-bearing moving platform 3 to move the spiral column 62 further away from the mounting block 153. Consequently, the center of gravity for stretching can be shifted to the latter half of the insulation tape stretching process, effectively increasing the quality of the produced insulation tape. In this device, the deformation of the spring replaces the simple tension spring, reducing the footprint of the elastic structure. Furthermore, the spring is naturally better than a linear tension spring in terms of the steepness of the initial tension increase. Simply put, compared to the tension deformation of a traditional spring, the spring requires less tension from the air-supplying tension member 5 to begin elastic deformation, while a traditional spring requires more. However, the final elastic deformation tension of both is almost the same. Therefore, in this device, the spring can further refine the initial fast-then-slow stretching time planning for the insulation tape, further improving the quality of the produced insulation tape.
