Description

Technical Field

[0001] This invention relates to the field of flame-retardant cable production equipment technology, and more specifically to an automated continuous production equipment for flame-retardant cables. Background Technology

[0002] Flame-retardant cables are cables that can inhibit or delay the spread of flames under specific flame conditions. Even if ignited, they can quickly self-extinguish after the fire source is removed, thus reducing the risk of fire. During the production of flame-retardant cables, flame-retardant tape or fiberglass tape, or other flame-retardant wrapping tapes, are wrapped around the cable to improve its flame-retardant performance. Continuous wrapping equipment, also known as wrapping devices or wrapping machines, is used during the wrapping process to improve the efficiency and quality of the wrapping.

[0003] Current flame-retardant cable production equipment still has the following problems when in use: 1. Flame-retardant cables pass through the inside of the wrapping equipment. The rotating wrapping equipment wraps the tape around the cable. Due to the tensile force during wrapping, the cable shakes due to the pull of the tape during the wrapping process, which leads to problems such as uneven wrapping and insufficient tightness, affecting the forming quality and flame-retardant performance of the flame-retardant cable.

[0004] 2. The existing equipment's material trays are mostly single and fixed. When the material tape is exhausted, the machine must be stopped and the empty material tray removed before a new material tray can be installed. Furthermore, the splicing position for material tape splicing is located inside the production equipment, which is inconvenient for wrapping splicing operations, thus affecting the splicing effect and wrapping quality of the wrapping tape.

[0005] 3. Existing wrapping equipment has poor adaptability. For cables of different diameters, the clamping mechanism and wrapping angle need to be manually adjusted. The adjustment process is complicated and prone to positioning deviation, which affects the wrapping accuracy.

[0006] Therefore, it is necessary to propose an automated continuous production equipment for flame-retardant cables to solve the above problems. Summary of the Invention

[0018] Compared with existing known technologies, the technical solution provided by this invention has the following significant advantages: 1. Through the coordinated design of the centrifugal assembly, telescopic tube assembly, and clamping assembly, the cable can be self-adaptively clamped, achieving automated cable fixation. Simultaneously, the arc-shaped plate and rollers on the clamping frame, in conjunction with the clamping rollers, prevent damage to the cable surface during clamping and provide stable restraint from both ends, effectively solving the problem of cable swaying caused by tape pulling during wrapping. This ensures the uniformity and tightness of the wrapping tape, improving the forming quality of the flame-retardant cable.

[0019] 2. The installation and unlocking mechanism, through the coordinated use of the fixing components and unlocking rod on the mounting sleeve, allows for quick installation, fixing, unlocking, and disassembly of the material tray rack. Multiple material tray racks can be stacked on the mounting sleeve, allowing for the addition of new trays without removing empty ones. The moving component drives the axial movement of the central tube, exposing the tape splice points for easier tape splicing and improving winding stability during continuous production. Furthermore, the coaxial design of the material rack and material tube allows for the pre-storage of multiple material tray racks, enabling rapid replenishment of new trays and significantly reducing downtime for tape replacement and splicing, thus meeting the continuous winding production requirements of long-distance flame-retardant cables.

[0020] 3. The arc plate in the clamping assembly can adapt to cables of different diameters through its elastic structure. The multiple convex edges and grooves of the telescopic tube assembly allow multiple clamping assemblies to move in a staggered manner without interfering with each other, improving the equipment's adaptability to different types of cables.

[0021] 4. During installation, the material tray frame achieves precise positioning through the cooperation of the guide groove and the protrusion, avoiding installation deviations from affecting the wrapping angle. The second guide rod is designed to correspond to the position of the material strip groove, which can keep the material strip winding angle constant without repeated adjustments.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] The conventional components and key load-bearing components in this case are selected in accordance with standards in terms of material selection, heat treatment process and structural dimensions to ensure that they have sufficient strength, stiffness and fatigue resistance under rated load and expected working conditions. These are all conventional design considerations well known to those skilled in the art.

[0026] Depend on Figures 1 to 13The device includes a frame 101, with a baffle 102 internally connected to support a splined sleeve 103. The splined sleeve 103 is rotatably connected to the baffle 102, with one end connected to a rotary drive device and the other end connected to a mounting sleeve 107. The splined sleeve 103 is rotatably connected internally to the baffle 102, with one end of the splined sleeve 103 externally connected to a rotary drive structure. A central tube 104 is splinedly connected internally to the splined sleeve 103, and the external part of the central tube 104 has a splined portion that mates with the splined sleeve 103, allowing the central tube 104 to move axially. A cable 105, which is a multi-strand cable or a single-strand cable to be wound, is threaded through the central tube 104. A rotating disk 106 is connected to one end of the central tube 104, and the rotating disk 106 rotates with the central tube 104. The rotating disk 106 is internally equipped with a centrifugal assembly. The higher the rotational speed of the central tube 104, the greater the range of motion of the centrifugal assembly. The central tube 104 is internally equipped with a telescopic tube assembly. One end of the telescopic tube assembly is connected to the centrifugal assembly, and the other end is connected to a clamping assembly between itself and the inner wall of the central tube 104. The clamping assembly contacts the cable 105. The rotating centrifugal assembly, through the telescopic tube assembly, drives the clamping assembly to clamp and fix the cable 105. When the central tube 104 is not rotating, the clamping assembly opens and does not fix the cable 105, facilitating the replacement and splicing of the cable roll. A moving assembly is connected between the baffle 102 and the rotating disk 106. The moving assembly pushes the rotating disk 106 to move axially; the moving assembly, through the rotating disk 106, drives the central tube 104 to move axially, thereby exposing the splicing position and enabling the splicing action.

[0027] A mounting sleeve 107 is connected to the outer wall of the splined sleeve 103 at the end away from the centrifugal assembly. The outside of the mounting sleeve 107 is used to mount multiple tray holders 108 for easy splicing and replacement of the feed tape. The tray holders 108 are wound with the feed tape to be used. A fixing component is provided inside the mounting sleeve 107 to secure the tray holders 108. A feed tape groove 109 is formed on the side wall of the central tube 104. In use, the feed tape passes through the feed tape groove 109 and is wound around the cable 105, serving to guide and restrict the feed tape.

[0028] When wrapping the cable tape, the cable 105 moves at a constant speed while the central tube 104 rotates. The rotating tape pulls on the cable 105, causing it to sway. This not only affects the cable 105 but also the wrapping quality. To address this, a structure is provided to maintain stable support: Specifically, the clamping assembly includes multiple clamping frames 201. Each clamping frame 201 has an arc-shaped plate 202 inside. The arc-shaped plate 202 has a U-shaped recess for contacting the cable 105. Multiple rollers 203 are rotatably connected inside the arc-shaped plate 202. When the clamping assembly rotates, the rollers 203 roll into contact with the cable 105, converting sliding friction into rolling friction and reducing wear on the cable surface. Roller 203 contacts cable 105. Both ends of the arc-shaped plate 202 are connected to clamping frame 201. In one embodiment, the arc-shaped plate 202 has elastic structures on both sides, allowing it to deform and adapt to cables 105 of different sizes or diameters, thus improving contact effectiveness. A first hinge rod 204 and a second hinge rod 205 are rotatably connected on the side of the clamping frame 201 away from the arc-shaped plate 202. The middle positions of the first hinge rod 204 and the second hinge rod 205 are rotatably connected by a pin. Both ends of the first hinge rod 204 are rotatably connected to the clamping frame 201 and the telescopic tube assembly, respectively. One end of the second hinge rod 205 is slidably connected to the clamping frame 201, and the other end is rotatably connected to the central tube 104. When the first hinge rod 204 and the second hinge rod 205 rotate, they cause the clamping frame 201 to move, thereby pressing against the surface of the cable and clamping and fixing it. To prevent cable 105 from shaking when it is wrapped with tape.

[0029] In one embodiment, to improve the contact effect when the roller 203 is connected to the cable, the roller 203 is replaced with a row of ball bearings to accommodate the axial movement of the cable. The ball bearing structure may include, for example, bullseye balls.

[0030] Since multiple sets of clamping components are provided, they may interfere with each other when operating simultaneously, thus affecting the clamping effect on the cable 105. Therefore, a structure is provided to stagger the multiple sets of clamping components: Specifically, the telescopic tube assembly includes a rotating tube 206 and a sliding tube 207 located within the central tube 104. The rotating tube 206 can only rotate within the central tube 104, and the sliding tube 207 can only slide within the central tube 104. One end of the sliding tube 207 is provided with multiple sets of protruding edges 208, each set having a different length. A groove 209 is formed between adjacent protruding edges 208, and the depth of each set of grooves 209 is different. (See structural reference). Figure 6 and Figure 7One end of the first hinge rod 204 is rotatably connected to the protruding edge 208. The interior of the central tube 104 is provided with a cavity to accommodate the protruding edge 208 and the groove 209. (Refer to...) Figure 5 , Figure 5 The central tube 104 has a cavity inside to accommodate the sliding tube 207. The cavity fits with the convex edge 208 and guides the sliding tube 207. Figure 7 The figure shows a planar unfolded view of the central tube 104 and the sliding tube 207. The lengths of the multiple convex edges 208 are different, and the depths of the grooves 209 are also different.

[0031] Specifically, three sets of clamping components are provided at the protruding edge 208 of the sliding tube 207 to clamp and fix one end of the wrapping tape; three sets of clamping components are provided at the groove 209 of the sliding tube 207 to clamp and fix the other end of the wrapping tape. This ensures that clamping components are provided at both ends of the wrapping tape position, allowing the cable 105 to be fixed from both sides, preventing the cable 105 from shaking during wrapping and improving stability.

[0032] When the sliding tube 207 moves toward the end closer to the rotating tube 206, the distance between the convex edge 208 and the groove 209 and the central tube 104 increases, thereby driving the clamping assembly to move.

[0033] In one embodiment, reference Figure 6 Since the three sets of clamping components are arranged in a circumferentially at equal intervals, grooves or slots that cooperate with another clamping frame 201 are provided at both ends or one end of the clamping frame 201. This results in overlapping areas between the three sets of clamping components, and the three sets will not collide with each other when they are in operation, further improving the clamping effect on the cable 105.

[0034] Since the sliding tube 207 needs to move axially within the central tube 104 when the central tube 104 rotates, the following structure is provided to drive the sliding tube 207 to move: Specifically, one end of the sliding tube 207 is sleeved on the outside of one end of the rotating tube 206, and one end of the rotating tube 206 and the sliding tube 207 overlap each other. A spiral groove 210 is formed on the outer wall of one end of the rotating tube 206, and a sliding pin is provided on the inner wall of the sliding tube 207 within the spiral groove 210. When the rotating tube 206 rotates, the sliding pin on the inner wall of the sliding tube 207 slides within the spiral groove 210, thereby sliding axially within the central tube 104. To prevent the rotating tube 206 from sliding axially, a limiting groove 211 is formed on the rotating tube 206, and a sliding pin located within the limiting groove 211 is connected to the inner wall of the central tube 104, so that the rotating tube 206 can only rotate within the central tube 104. When the rotating tube 206 rotates, it drives the sliding tube 207 to slide axially within the central tube 104, thereby driving the clamping assembly to perform automated clamping actions.

[0035] When the central tube 104 stops, the internal clamping assembly opens. When the central tube 104 rotates, the internal clamping assembly automatically clamps the cable 105, thus keeping the cable 105 centered. A structure is needed to automatically drive the rotating tube 206 to rotate according to the rotation. The following provides a structure for automatically driving the rotating tube 206 to rotate: Specifically, the rotating disk 106 has an arc-shaped groove 301 inside, with one end facing the axis of the rotating disk 106 and the other end facing away from the axis. The centrifugal assembly includes a centrifugal block 302 slidably connected within the arc-shaped groove 301. A rotating frame 303 is rotatably connected within the rotating disk 106, and the rotating frame 303 is connected to one end of the rotating tube 206. When the rotating frame 303 rotates, it drives the rotating tube 206 to rotate. The rotating frame 303 has centrifugal grooves 304 at both ends. One end of the centrifugal block 302 is slidably connected within the centrifugal groove 304. The centrifugal block 302 and the rotating disk 106 are connected by a spring. The spring keeps the centrifugal block 302 at the axis within the rotating disk 106. When the central tube 104 rotates, it drives the rotating disk 106 to rotate. The centrifugal block 302 inside the rotating disk 106 is subjected to centrifugal force and moves outward within the arc-shaped groove 301. The other end of the centrifugal block 302 moves within the centrifugal groove 304, thereby driving the rotating frame 303 to rotate. The rotating frame 303 then drives the rotating tube 206 to rotate. This achieves the function of automatically controlling the clamping assembly. An internal structure is provided to limit the end of the centrifugal assembly to prevent over-clamping.

[0036] When wrapping cable 105, because the cable is long, one roll of tape is insufficient to wrap the produced flame-retardant cable, so multiple rolls of tape are required. However, since the wrapping point of the tape is located inside the central tube 104, it is inconvenient to perform tape splicing. The following provides a structure to facilitate tape splicing: Specifically, the moving component includes a moving frame 305 rotatably connected to the outside of the rotating disk 106, and the rotating disk 106 rotatably connected to the inside of the moving frame 305. An electric telescopic rod 306 is connected between the moving frame 305 and the baffle 102. When the electric telescopic rod 306 extends, it will drive the rotating disk 106 to move through the moving frame 305, thereby driving the central tube 104 to move. This exposes the splicing point for easy splicing. An optical axis 307 is connected between the baffle 102 and the frame 101. The optical axis 307 has a guiding function, allowing the moving frame 305 to move only axially. The movable frame 305 is slidably connected to the optical axis 307. A motor 308 is connected inside the frame 101. The output end of the motor 308 is connected to the spline sleeve 103 via a chain drive structure 309. The chain drive structure 309 consists of a chain and a sprocket. The motor 308 drives the spline sleeve 103 to rotate through the chain drive structure 309, and the spline sleeve 103 drives the central tube 104 to rotate through the spline connection. In one embodiment, the chain drive structure 309 is replaced by a belt drive structure with a tensioning device to increase the wrap angle during transmission.

[0037] When a new material roll needs to be replaced, the used material tray frame 108 cannot be disassembled due to the obstruction of the cable 105. Simultaneously, a new material tray frame 108 needs to be installed on the mounting sleeve 107. The following provides a structure to facilitate the installation of a new material tray frame 108: Specifically, a material tray 401 is connected to one end of the mounting sleeve 107 near the centrifugal assembly. The material tray 401 obstructs the material tray frame 108 containing the material roll, acting as a limiting device. It also serves to mount the first guide rod 501 and the second guide rod 502. The fixing assembly includes multiple locking posts 402 slidably connected within the mounting sleeve 107. The top of each locking post 402 has an inclined surface on the side away from the material tray 401. The inner ring surface of the material tray frame presses against the inclined surface at the top of the locking post 402, causing the locking post 402 to move downwards. The inner circumference of the tray frame 108 is provided with a slot corresponding to the top of the retaining post 402. When the tray frame 108 is fitted onto the mounting sleeve 107, and the slot on the inner side of the tray frame 108 aligns with the top of the retaining post 402, the retaining post 402 is inserted into the slot under the action of a spring, thus fixing the tray frame 108. The retaining post 402 and the mounting sleeve 107 are connected by a spring. The mounting sleeve 107 has guide grooves 403 on both sides, and the inner wall of the tray frame 108 has protrusions corresponding to the guide grooves 403. The guide grooves 403 serve to guide and position, preventing the tray frame 108 from rotating on the mounting sleeve 107. Multiple retaining posts 402 are provided. When a roll of material is used up, it is not disassembled; a new tray frame 108 is directly installed on the mounting sleeve 107. This process is repeated, allowing multiple rolls of material to be used to complete the winding of flame-retardant tape. The second guide rod 502, whose position remains unchanged, prevents angle changes. Changes in angle would affect the wrapping effect and parameters of the strap.

[0038] After production is completed, the empty tray rack 108 needs to be removed from the mounting sleeve 107 to facilitate the next production run. The following provides a structure for easily removing multiple used tray racks 108: Specifically, the locking post 402 has an inclined pressing part 404 inside, and an unlocking rod 405 is slidably connected inside the mounting sleeve 107. The unlocking rod 405 can move within the mounting sleeve 107, with the direction of movement parallel to the axis of the mounting sleeve 107. A pressing part 406 corresponding to the inclined pressing part 404 is connected to the unlocking rod 405. When the unlocking rod 405 moves, the pressing part 406 at the bottom contacts the inclined pressing part 404 of the locking post 402, thereby pressing down the locking post 402. At this time, the locking post 402 will be pulled out of the slot in the tray rack 108, losing its ability to fix the tray rack 108. One end of the unlocking rod 405 extends out of the mounting sleeve 107, and the unlocking rod 405 is connected to the mounting sleeve 107 by a spring. The spring pushes the unlocking rod 405 outward, and the initial reset state of the unlocking rod 405 is that it is extended outward, so that the pressing part 406 is separated from the inclined pressing part of the locking post 402. The top of the inclined pressing part 404 is provided with a cavity, so that the locking post 402 has space to move downward. When the tray frame 108 is installed, the locking post 402 will be squeezed, so that it enters the mounting sleeve 107 to facilitate the installation of the tray frame 108 without affecting the unlocking rod 405. The pressed-down locking post 402 is referenced. Figure 12 For splicing two reels of material, a special wrapping tape will be used. (See reference...) Figure 13 The red position on cable 105 indicates the splicing point.

[0039] After changing the material roll, the change in position will cause a change in the winding position. To avoid changes in the angle of the material strip, the following structure is provided to guide the material strip: Specifically, a first guide rod 501 and a second guide rod 502 are connected to the material tray 401. The second guide rod 502 is inclined to keep the winding angle unchanged. In one embodiment, the length of the first guide rod 501 can be extended to accommodate the position change of the new material roll. The first guide rod 501 and the second guide rod 502 guide the material strip on the material tray frame 108, and the position of the second guide rod 502 corresponds to the material strip groove 109. In one embodiment, to increase the thickness of the flame retardant layer, a double winding method is used. Therefore, two sets of first guide rods 501 and second guide rods 502 are provided on the material tray 401 for the wrapping work. Although the position of the new material strip changes, the positions of the first guide rods 501 and the second guide rods 502 are fixed and will not change the angle of the material strip when it exits, thus maintaining the winding position unchanged.

[0040] The device is equipped with a detection device to monitor the condition of the conveyor belt, so that users can replace it in a timely manner. This is an existing and mature structure, and will not be described in detail here.

[0041] Due to the obstruction of cable 105, and the inconvenience of installing the new material tray rack 108, the following structure is provided to support the new material tray rack 108 for storing new material rolls to be used: Specifically, a material rack 503 is provided on the outside of the frame 101, and there is a distance between the material rack 503 and the frame 101 to facilitate the replacement and observation of the material rolls. A material tube 504, coaxially aligned with the central tube 104, is provided on the material rack 503, and multiple material tray racks 108 are placed on the material tube 504. The material tray rack 108 to be used is placed on the material tube 504, and when needed, it is directly pushed into the mounting sleeve 107 for installation.

[0042] In use, the new roll of material to be used is placed on the material tube 504. The cable 105 passes through the inside of the central tube 104 and the material tube 504. The material strip on the material tray frame 108 is passed through the first guide rod 501 and the second guide rod 502 and then wound around the cable 105. The motor 308 drives the spline sleeve 103 to rotate through the chain transmission structure 309. The spline sleeve 103 is connected by splines, which drives the internal central tube 104 to rotate. Under the action of centrifugal force, the centrifugal component drives the clamping component to move through the telescopic tube component, which automatically clamps and fixes the cable 105 to prevent the cable 105 from shaking.

[0043] When the material strip on the tray frame 108 has been used to a certain extent, the motor is stopped, a new roll of material is installed on the mounting sleeve 107, and the material strip is continued on the cable 105 to facilitate continuous winding production of the material strip.

[0044] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
