Description

Technical Field

[0001] This invention belongs to the field of cable manufacturing technology, and specifically relates to a cotton cloth wrapping and tightening device for cable production. Background Technology

[0002] In the cable manufacturing industry, especially in the cabling process of power cables and control cables, soft tapes such as cotton tape and non-woven tape are often used to wrap the insulated wire cores or the cable cores after cabling. The main purpose is to tighten the wire cores, prevent loosening, provide heat insulation and buffering, and serve as an intermediate lining for waterproofing or enhancing mechanical strength.

[0003] Currently, commonly used cotton cloth wrapping and tightening devices typically include a tape release mechanism, a wrapping head, and a tension control device. Their working principle involves using the rotational motion of the wrapping head to spirally wrap the cotton cloth around the linearly advancing cable core. After wrapping, the cotton cloth layer is essentially still a loose aggregate, making it susceptible to loosening due to external factors in subsequent processes. This results in poor wrapping and tightening effects. Summary of the Invention

[0020] In one possible embodiment, the transfer member is a flexible material having a cavity inside, the cavity being filled with contents.

[0021] In one possible embodiment, the outer periphery of the transmission element is provided with a wear-resistant layer.

[0028] A transmission bevel gear ring is rotatably connected to the inner wall of the processing cylinder. The transmission bevel gear ring rotates about the axial direction of the processing cylinder, and also meshes with the transmission bevel gear; and

[0029] A synchronizing element is connected to the transmission bevel gear ring, and the synchronizing element is used to drive the transmission bevel gear ring to rotate.

[0030] In one possible embodiment, the coating unit further includes:

This invention actively applies a continuous, centripetal wrapping force through the synergistic effect of "mechanical compression" and "adhesive curing," and uses adhesive to bond the cotton cloth fibers together into a solid whole. This not only eliminates the gap between the cotton cloth layer and the cable core, but more importantly, through the curing effect of the adhesive, it permanently locks in the compressed state, transforming the cotton cloth layer from a "loose aggregate" into a "solid composite material layer," thereby eliminating the physical basis for loosening and achieving the goal of improving the wrapping effect of the cotton cloth layer.

[0053] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present 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 merely illustrative of the present invention and are not intended to limit the present invention.

[0054] Please refer to the following: Figures 1 to 8This invention describes a cotton cloth wrapping and tightening device for cable production. The device includes a wrapping unit 10, a fastening unit 20, and an adhesive coating unit 30. The wrapping unit 10 is used to wrap cotton cloth around the outer periphery of the cable core to form a cotton cloth layer. Two wrapping units 10 are provided, and the wrapping unit 10 is prior art, so it will not be described again in this application. The fastening unit 20 is located on one side of the wrapping unit 10, specifically, on the front side of the wrapping unit 10. The fastening unit 20 includes a processing cylinder 201 fixed to the ground and multiple pressing structures located on the inner periphery of the processing cylinder 201. The multiple pressing structures are spaced apart around the axis of the processing cylinder 201. The device includes a pressing shaft 202 and a rotating component 203 connected to the pressing shaft 202. The rotating component 203 is used to drive the pressing shaft 202 to rotate. The rotating component 203 is a servo motor. The pressing shaft 202 has a glue storage cavity 2021 inside. The outer wall of the pressing shaft 202 has multiple glue outlets 2022 arranged in a row. The glue outlets 2022 are arranged in multiple rows around the axis of the pressing shaft 202. The glue coating unit 30 includes a glue tank connected to the glue storage cavity 2021 and a glue injection structure disposed in the glue storage cavity 2021. The glue injection structure sprays the glue liquid in the glue storage cavity 2021 onto the cotton cloth layer through the glue outlets 2022.

[0055] It should be noted that, Figure 1 The direction indicated by the middle arrow is the front.

[0056] The cable production cotton cloth wrapping and tightening device provided in this embodiment allows the cable core to advance in a straight line. The wrapping unit 10 spirally wraps the cotton cloth around the outer circumference of the cable core to form a preliminary cotton cloth layer. The cable core wrapped with the cotton cloth layer then enters the processing cylinder 201. The pressing shaft 202 rotates under the drive of the rotating component 203. The rotation of the pressing shaft 202 causes the cotton cloth to move along the wrapping direction, thereby tightening the cotton cloth layer again. At the same time as the pressing shaft 202 contacts the cotton cloth layer, the glue coating unit 30 sprays the glue liquid in the glue storage chamber 2021 from the glue outlet 2022 onto the cotton cloth layer that is being tightened. Under the continuous rolling pressure of the pressing shaft 202, the glue liquid gradually penetrates the cotton cloth layer impregnated with the glue liquid. After the glue liquid solidifies, the loose cotton cloth fibers are bonded into a tight whole and firmly attached to the cable core.

[0057] Compared to existing technologies, this invention integrates the winding unit 10 and the fastening unit 20, performing fastening immediately after the cotton fabric is wound. The fastening unit 20 uses multiple self-rotating pressure shafts 202 to roll the cotton fabric layer, while simultaneously spraying adhesive through the adhesive coating unit 30. This invention actively applies a continuous, centripetal wrapping force through the synergistic effect of "mechanical compression" and "adhesive curing," bonding the cotton fabric fibers together into a robust whole using adhesive. This not only eliminates the gap between the cotton fabric layer and the cable core, but more importantly, through the curing effect of the adhesive, it permanently locks in the compressed state, transforming the cotton fabric layer from a "loose aggregate" into a "robust composite material layer," thereby eliminating the physical basis for loosening and achieving the goal of improving the wrapping effect of the cotton fabric layer.

[0058] In some embodiments, see Figures 2 to 5 The glue injection structure corresponds one-to-one with the glue outlet 2022. A stop post 2023 is provided inside the glue outlet 2022. The diameter of the stop post 2023 gradually decreases from the inside to the outside of the pressure shaft 202. The stop post 2023 is slidably connected to the pressure shaft 202. The stop post 2023 moves radially along the pressure shaft 202. An elastic member 2024 is fixedly connected between the stop post 2023 and the pressure shaft 202. The elastic member 2024 has a pre-tightening force that causes the stop post 2023 to extend from inside the glue outlet 2022 to the outside. The elastic member 2024 is a spring or a spring rod.

[0059] The glue injection structure includes a glue injection cylinder 301, a pressure plate 302, and a power assembly. The glue injection cylinder 301 is fixed to the inner wall of the glue storage cavity 2021 and extends radially along the pressing shaft 202. The pressure plate 302 is disposed inside the glue injection cylinder 301 and is slidably connected to the glue injection cylinder 301. The pressure plate 302 moves along the extending direction of the glue injection cylinder 301. The power assembly is driven to the pressure plate 302 and is used to drive the pressure plate 302 to move.

[0060] When the baffle 2023 is not in contact with the cotton cloth layer, the baffle 2023 extends under the action of the elastic element 2024 and tightly seals the glue outlet 2022; when the baffle 2023 is in contact with the cotton cloth layer, the baffle 2023 is pressed back inward by the cotton cloth layer, and the conical structure of the baffle 2023 generates a scraping effect on the inner wall of the glue outlet 2022 during the sliding process, which plays a dynamic self-cleaning role and ensures the smooth flow of the glue outlet channel.

[0061] In addition, the linear movement of the pressure plate 302 within the glue injection cylinder 301 generates spray pressure, causing the glue to actively penetrate into the gaps between the cotton fibers rather than passively seeping out. This enhances the penetration depth and uniformity of the glue, ensuring a strong bond is formed both inside the cotton layer and between it and the cable core, rather than just on the surface.

[0062] This invention ensures that the adhesive is only triggered to spray at the moment when the clamping shaft 202 makes substantial contact with the cotton cloth layer and generates clamping force. This "contact-to-spray, separation-to-stop" working mode fundamentally eliminates the waste and ineffective application of adhesive, achieving energy saving and consumption reduction.

[0063] Optionally, the power unit is a telescopic cylinder or a hydraulic cylinder.

[0064] When the dispensing port 2022 is opened, the power unit is activated to drive the pressure plate 302 to squeeze the adhesive, thereby forcing the adhesive to spray out from the dispensing port 2022.

[0065] In some embodiments, see Figure 5 The power assembly includes a deflector block 303, a downward pressure rod 304, a deformation component 305, an upward lifting rod 306, and a transmission component 307. The deflector block 303 is fixed to the inner wall of the glue storage cavity 2021. The deflector block 303 has a first groove 3031 and a second groove 3032 on the side facing the corresponding glue outlet 2022. The deflector block 303 also has a through groove 3033 connecting the first groove 3031 and the second groove 3032. The downward pressure rod 304 is fixed to the side of the pressure plate 302 away from the glue outlet 2022. One side of the pressure plate 302 extends into the two sliding grooves; the deformation member 305 is fixed between the lower pressure rod 304 and the deflector block 303. The deformation member 305 has a pre-tightening force that causes the lower pressure rod 304 to move away from the corresponding glue outlet 2022. The deformation member 305 is a spring or a spring rod; one end of the lifting rod 306 is fixed to the stop post 2023, and the other end extends into the first sliding groove 3031; the transmission member 307 is provided in the through groove 3033. The transmission member 307 is used to transmit the extrusion force of the lifting rod 306 to the lower pressure rod 304.

[0066] By cleverly utilizing the stop post 2023 as a "sensor" to detect the contact of the cotton fabric layer, and then using the mechanical linkage mechanism composed of the lifting rod 306, the transmission component 307 and the pressing rod 304 as a "controller", the glue pressing plate 302, the "actuator", is finally driven to complete the glue injection. This fully mechanical transmission method eliminates the vulnerability of electronic sensors and circuits in industrial environments with severe interference such as humidity, fundamentally eliminating the risk of malfunctions or shutdowns caused by sensor failure, signal interference or circuit failure, and ensuring the continuity and stability of the production process.

[0067] In addition, the preload provided by the deformable part 305 not only ensures the timely reset of the system, but also gives the pressure rod 304 a definite initial position, making the force and stroke relationship of the entire triggering process stable and reliable, avoiding action delay or inconsistency caused by looseness or misalignment, thereby ensuring that the outer periphery of the cotton cloth layer is uniformly and fully coated with adhesive.

[0068] In some embodiments, see Figure 5The transmission component 307 is a flexible material, and a cavity is provided inside the transmission component 307. The cavity is filled with contents, which can be hydraulic oil or particulate matter.

[0069] By squeezing the transmission member 307, the transmission member 307 is deformed, and the deformation of the transmission member 307 squeezes the pressure rod 304, causing the pressure rod 304 to push the pressure plate 302.

[0070] The content of the contents can be varied according to demand. The greater the content of the contents, the greater the stroke of the pressure rod 304; the smaller the content of the contents, the smaller the stroke of the pressure rod 304.

[0071] In some embodiments, the outer periphery of the transfer member 307 is provided with a wear-resistant layer.

[0072] By adding a wear-resistant layer, the wear resistance of the transmission component 307 is improved, thereby increasing the service life of the transmission component 307.

[0073] In some embodiments, see Figure 2 and Figure 6 The fastening unit 20 also includes an annular support frame 204, multiple lifting rollers 205, and an adjusting sleeve 206; the support frame 204 is fixed to the inner wall of the processing cylinder 201; the multiple lifting rollers 205 are spaced apart around the axis of the support frame 204, and the lifting rollers 205 are slidably connected to the support frame 204 along the radial direction of the processing cylinder 201; the pressing structure is located at the end of the lifting roller 205 away from the inner wall of the processing cylinder 201; the adjusting sleeve 206 corresponds one-to-one with the lifting rollers 205, the adjusting sleeve 206 is screwed to the outer circumference of the lifting roller 205, and the adjusting sleeve 206 is also rotatably connected to the support frame 204, and the rotation axis of the adjusting sleeve 206 is parallel to the radial direction of the support frame 204.

[0074] Specifically, the fastening unit 20 also includes a transmission bevel gear 207, a transmission bevel gear ring 208, and a synchronizing element 209; the transmission bevel gear 207 corresponds one-to-one with the adjusting sleeve 206, and the transmission bevel gear 207 is fixedly connected to the outer periphery of the adjusting sleeve 206; the transmission bevel gear ring 208 is rotatably connected to the inner wall of the processing cylinder 201, and the transmission bevel gear ring 208 rotates about the axial direction of the processing cylinder 201, and meshes with the transmission bevel gear 207; the synchronizing element 209 is connected to the transmission bevel gear ring 208, and the synchronizing element 209 is used to drive the transmission bevel gear ring 208 to rotate. The synchronizing element 209 is a servo motor, and the output shaft end of the synchronizing element 209 is fixedly connected to a drive gear 2091, and the inner wall of the transmission bevel gear ring 208 is fixedly connected to a drive gear ring 2081 that meshes with the drive gear 2091.

[0075] Synchronizer 209 starts and drives drive gear 2091 to rotate. Drive gear 2091 drives drive gear ring 2081 to rotate. Drive gear ring 2081 drives transmission bevel gear ring 208 to rotate. Transmission bevel gear ring 208 drives transmission bevel gear 207 to rotate. Transmission bevel gear 207 drives adjustment sleeve 206 to rotate. Adjustment sleeve 206 drives lifting roller 205 to move radially along support frame 204, thereby adjusting the diameter of the area enclosed by the pressing structure to meet the production needs of cable cores of different diameters. At the same time, all pressing structures are adjusted synchronously to ensure that the distance between the pressing structure and the axis of processing cylinder 201 is consistent.

[0076] In some embodiments, see Figure 4 and Figure 6 The glue coating unit 30 also includes a fixed plate 308 and a glue inlet pipe 309. The fixed plate 308 is fixedly connected to the end of the lifting roller 205. The fixed plate 308 has a first glue inlet channel 3081. The pressing shaft 202 is rotatably connected to the fixed plate 308. The pressing shaft 202 has a second glue inlet channel 2025 that connects the first glue inlet channel 3081 and the glue storage cavity 2021. One end of the glue inlet pipe 309 is connected to the glue tank, and the other end passes through the first glue inlet channel 3081 and the second glue inlet channel 2025 in sequence and extends into the glue storage cavity 2021. The glue inlet pipe 309 is fixedly connected to the fixed plate 308.

[0077] When the lifting roller 205 drives the entire pressing structure to move radially, the fixed plate 308 fixed to the end of the lifting roller 205 moves synchronously. The glue inlet pipe 309 is connected to the fixed plate 308 fixed on the corresponding lifting roller 205. It is only necessary to ensure that the glue inlet pipe 309 has sufficient length margin to accommodate this radial movement during the initial installation. Thus, the glue supply system does not need to undergo any additional complex disassembly or adjustment during the process of adjusting the position of the pressing shaft 202 to adapt to different cable specifications, and always ensures the integrity of the seal and the unobstructed glue path.

[0078] In some embodiments, see Figure 7 The support frame 204 has a through hole 2041 for the lifting roller 205 to pass through. A guide block 2042 is fixed to the inner wall of the through hole 2041. The outer wall of the lifting roller 205 has a guide groove 2051 that is slidably adapted to the guide block 2042. The guide groove 2051 extends along the axial direction of the lifting roller 205.

[0079] During the rotation of the adjusting sleeve 206, the guide block 2042 slides in the guide groove 2051, thereby restricting the movement of the lifting roller 205, so that the lifting roller 205 can only move radially along the support frame 204.

[0080] In some embodiments, see Figure 3 and Figure 8The pressing shaft 202 has a glue-brushing groove 2026 between two adjacent glue outlets 2022, and the glue-coating unit 30 also includes a glue-brushing structure disposed in the glue-brushing groove 2026.

[0081] The adhesive application structure includes a brush 310, an extruder 311, a power component 312, and an elastic component 313. The brush 310 is slidably connected to the pressing shaft 202 and moves axially along the pressing shaft 202. A protrusion 3101 is fixedly connected to the side of the brush 310 away from the opening of the adhesive application groove 2026. The extruder 311 is rotatably connected to the pressing shaft 202. The rotation axis of the extruder 311 is perpendicular to the moving direction of the brush 310. The extruder 311 has a first working state of extruding the protrusion 3101 and a second working state of moving away from the protrusion 3101. The power component 312 is drivenly connected to the extruder 311 and is used to drive the extruder 311 to rotate. The power component 312 is a servo motor. The elastic component 313 is fixedly connected between the protrusion 3101 and the pressing shaft 202. The elastic component 313 has a preload force that causes the protrusion 3101 to move toward the extruder 311.

[0082] Optionally, the extrusion part 311 is a cam.

[0083] Optionally, the extrusion part 311 is an extrusion rod.

[0084] The power component 312 starts and drives the extruder 311 to rotate, causing the extruder 311 to intermittently extrude the protrusion 3101. Through the cooperation of the elastic component 313, the brush 310 moves back and forth along the axial direction of the pressing shaft 202.

[0085] During the reciprocating motion of the brush 310, the surface of the glue-impregnated cotton cloth layer is scraped and brushed, smoothing out any glue accumulation caused by uneven spray pressure or flow, ensuring that the glue layer is uniform on the cotton cloth surface, and avoiding hardened lumps caused by excessive glue in some areas or weak bonding points caused by insufficient glue in some areas.

[0086] The scraping action of the brush 310 applies a tangential force to the cotton fabric layer, which complements the compressive force. This effectively forces the surface adhesive into the deep fiber gaps of the cotton fabric weave and into the microscopic gaps between the cotton fabric layer and the cable core, maximizing the elimination of air and ensuring the full wetting of the fibers by the adhesive. This results in a stronger and denser three-dimensional bonding network at the microscopic level, significantly enhancing the overall structural strength of the cotton fabric layer and its adhesion to the cable core.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
