Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and more specifically, to a cable core coating and forming apparatus for cable processing. Background Technology

[0002] The cable core coating molding device for cable processing is a device used to coat the surface of the cable core with cross-linked polyethylene insulation material to form a cable semi-finished or finished product with specific insulation properties, mechanical protection and protective functions. Through processes such as heating and melting the material, conveying and plasticizing and directional extrusion coating, as well as traction and shaping, the insulation layer is tightly attached to the surface of the cable core.

[0003] During the storage and transportation of cable cores, they may come into contact with contaminants, leading to surface stains. Even with a separate cleaning process before insulation coating, there is still a chance of contact with contaminants during transfer. Directly coating the cable core with insulation material at this point can reduce insulation adhesion, making it prone to bubbles, voids, or delamination, increasing the risk of short circuits, deteriorating electrical performance, lowering insulation breakdown voltage, potentially causing partial discharge or short circuit faults, and affecting the cable's processing quality. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a cable core coating and forming device for cable processing, so as to solve the problem that the surface of the cable core is easily contaminated with stains and that directly coating with insulation materials can easily lead to a decline in cable quality.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A cable core coating forming device for cable processing includes a support platform, on the upper surface of which an extrusion coating assembly is fixedly connected. It also includes a cleaning mechanism located at the rear of the extrusion coating assembly. The cleaning mechanism includes a receiving platform fixedly connected to the rear end of the support platform. Multiple supports are fixedly connected to both sides of the receiving platform. A primary cleaning chamber and a secondary cleaning chamber are fixedly connected between two sets of supports. The primary cleaning chamber is located at the rear end of the secondary cleaning chamber. A flushing pipe is fixedly inserted into the bottom of both the primary and secondary cleaning chambers. A drain pipe connects to the bottom of both the primary and secondary cleaning chambers. The bottom end of the flushing pipe is connected to an external water source to provide water.

[0007] Furthermore, the rear end of the secondary cleaning chamber is rotatably connected to multiple support shafts, which are arranged in pairs. The rear ends of each support shaft are fixedly connected to a drive shaft, and two corresponding drive shafts are connected by a wiping belt.

[0008] Furthermore, a rotating ring is fixedly connected to the rear end of the secondary cleaning chamber, and a rotating cover is rotatably connected to the surface of the rotating ring. A driven wheel is fixedly connected to the surface of either of the two drive shafts, and the driven wheel is in contact with the inner wall of the rotating cover. A motor is fixedly connected to the rear end of the secondary cleaning chamber, and a drive wheel is fixedly connected to the output shaft of the motor. A rubber ring is fixedly sleeved on the surface of the rotating cover, and the drive wheel is in contact with the rubber ring.

[0009] Furthermore, a support ring is fixedly connected to the rear end of the secondary cleaning chamber, and multiple torsion limiting shafts are rotatably connected inside the support ring.

[0010] Furthermore, both the primary and secondary cleaning chambers are fixedly connected to the top of their interiors with suspension frames, and pressure rollers are rotatably connected to the surface of the suspension frames.

[0011] Furthermore, a straight pipe is connected to the rear end of the secondary cleaning chamber.

[0012] Furthermore, the bottom ends of the two drain pipes are connected to a water suction pipe, a water pump is fixedly connected to the upper surface of the support platform, a cooling rack is connected to the upper surface of the support platform, the cooling rack is located in front of the extrusion coating assembly, the front end of the water suction pipe is connected to the water inlet of the water pump, the water outlet of the water pump is connected to a water delivery pipe, the front end of the water delivery pipe is connected to a cooling nozzle, and the front end of the water delivery pipe is fixedly inserted into the interior of the cooling rack.

[0013] Furthermore, a water-absorbing chamber pipe is fixedly connected to the front end of the straight pipe, and a sponge column is fixedly connected inside the water-absorbing chamber pipe.

[0014] Furthermore, the upper surface of the water absorption chamber is connected to a ventilation pipe, the lower right end of the ventilation pipe is connected to a water removal chamber, a heating and evaporating copper core is fixedly connected inside the water removal chamber, multiple heating rods are fixedly inserted inside the heating and evaporating copper core, and an exhaust pipe is connected to the lower surface of the water absorption chamber.

[0015] Furthermore, the upper surface of the heating and evaporating copper core is provided with multiple vent holes, and a hot air delivery exhaust fan is fixedly connected inside the ventilation pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) When the cable core enters the first-level cleaning chamber, the stains on the surface of the cable core can be rinsed first to reduce the impact of the residual stains on the surface of the cable core on the quality of the subsequent cable core insulation material coating. Some stubborn stains that cannot be rinsed off can also be softened.

[0017] (2) This solution uses a wiping strip to rub the surface of the cable core to wipe and rinse away the water-soaked and softened stains remaining on the surface of the cable core, thereby further reducing the impact of the residual stains on the surface of the cable core on the quality of the subsequent cable core insulation material coating.

[0018] (3) This solution uses a water pump to transport water from the primary cleaning chamber and the secondary cleaning chamber to the water supply pipe and spray it out through the cooling nozzle. This can cool and solidify the insulation material being covered. Furthermore, the water consumption required during the covering process can be reduced by using water in multiple ways.

[0019] (4) This solution can absorb most of the water stains through the sponge column inside the water absorption chamber. Then, when the water stains inside the copper core are removed by heating and evaporation, the remaining water stains will be evaporated and removed, preventing the water stains on the surface of the cable core from having an adverse effect on the quality of the cable core insulation material. Furthermore, by cleaning most of the water first and then cleaning the remaining water, the cleaning speed of the water stains can be accelerated, the cleaning effect can be improved, and the travel distance of the cable core water removal process can be reduced.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-9 A cable core coating forming device for cable processing includes a support platform 1. An extrusion coating assembly 2 is fixedly connected to the upper surface of the support platform 1. The device also includes a cleaning mechanism located at the rear of the extrusion coating assembly 2. The cleaning mechanism includes a receiving platform 303 fixedly connected to the rear end of the support platform 1. The receiving platform 303 can collect water overflowing during the cleaning process, preventing excessive moisture in the processing environment. Multiple supports 302 are fixedly connected to both sides of the receiving platform 303. A primary cleaning chamber 304 and a secondary cleaning chamber 301 are fixedly connected between two sets of supports 302. The primary cleaning chamber 304 is located at the rear end of the secondary cleaning chamber 301. Both the primary cleaning chamber 304 and the secondary cleaning chamber 301 have flushing pipes 313 fixedly inserted inside their bottom ends. Both the primary cleaning chamber 304 and the secondary cleaning chamber 301 have drain pipes 314 connected to their bottom ends. The bottom end of the flushing pipe 313 is connected to an external water source to provide water. The flushing pipe 313 connected to the external water source can transport water to the primary cleaning chamber 304 and the secondary cleaning chamber 301, allowing water to fill the primary cleaning chamber 304 and the secondary cleaning chamber 301.

[0024] The secondary cleaning chamber 301 is rotatably connected to a plurality of support shafts 322 at its rear end. These support shafts 322 are arranged in pairs, and each support shaft 322 has a drive shaft 325 fixedly connected to its rear end. Two corresponding drive shafts 325 are connected via a wiping belt 323, which rubs against the surface of the cable core to wipe away water-softened stains remaining on the cable core surface. A rotating ring 320 is fixedly connected to the rear end of the secondary cleaning chamber 301. A rotating cover 316 is rotatably connected to the surface of the rotating ring 320. A driven wheel 324 is fixedly connected to the surface of any one of the two corresponding drive shafts 325, and the driven wheel 324 is in contact with the inner wall of the rotating cover 316. A motor 317 is fixedly connected to the rear end of the secondary cleaning chamber 301. A drive wheel 318 is fixedly connected to the output shaft of the motor 317. The motor 317 drives the drive wheel 318 to rotate, which in turn drives the rotating cover 316 to rotate. A rubber ring 319 is fixedly sleeved on the surface of the rotating cover 316. The rotating cover 316 can drive multiple passive wheels 324 to rotate simultaneously. The drive wheel 318 is in contact with the rubber ring 319.

[0025] The secondary cleaning chamber 301 is fixedly connected to a support ring 321 at its rear end. Multiple torsion limiting shafts 326 are rotatably connected inside the support ring 321. When the wiping belt 323 wipes the cable core, the friction between the cable core and the wiping belt 323 may cause the cable core to rotate. The torsion limiting shafts 326 fix the cable core in place, and the friction between the torsion limiting shafts 326 and the cable core prevents the cable core from rotating without affecting its normal traction movement. Suspension frames 311 are fixedly connected to the top of the interior of both the primary cleaning chamber 304 and the secondary cleaning chamber 301. Pressure rollers 312 are rotatably connected to the surface of the suspension frames 311. The pressure rollers 312 keep the cable core bent downwards as it passes through the primary and secondary cleaning chambers 304 and 301, reducing the amount of water carried out when the cable core leaves the primary and secondary cleaning chambers 304 and 301. The rear end of the secondary cleaning chamber 301 is connected to a straight pipe 315. The straight pipe 315 can straighten the bent cable core when it is removed from the secondary cleaning chamber 301, so as to prevent the cable core from being uneven in thickness due to insufficient straightness when it enters the extrusion coating assembly 2.

[0026] The bottom ends of the two drain pipes 314 are connected to suction pipes 305. A water pump 307 is fixedly connected to the upper surface of the support platform 1, and a cooling rack 309 is connected to the upper surface of the support platform 1. The cooling rack 309 is located in front of the extrusion coating assembly 2. The front end of the suction pipe 305 is connected to the inlet of the water pump 307, and the outlet of the water pump 307 is connected to a water delivery pipe 306. The front end of the water delivery pipe 306 is connected to a cooling nozzle 308, and the front end of the water delivery pipe 306 is fixedly inserted into the interior of the cooling rack 309. The water pump 307 delivers water from the primary cleaning chamber 304 and the secondary cleaning chamber 301 to the water delivery pipe 306 and sprays it out through the cooling nozzle 308 to cool the insulating material, which can reduce the amount of water required during the coating process.

[0027] By adopting the above technical solution, before coating the cable core with insulation material, the cable core is inserted and passes through the primary cleaning chamber 304 and the secondary cleaning chamber 301 into the extrusion coating assembly 2, and is moved by a traction device. During the movement of the cable core, the flushing pipe 313 connected to an external water source can transport water to the primary cleaning chamber 304 and the secondary cleaning chamber 301, allowing water to fill and flow inside them. When the cable core enters the primary cleaning chamber 304, the dirt on the surface of the cable core can be rinsed first, reducing the impact of residual dirt on the subsequent coating quality of the cable core insulation material. Some stubborn dirt that cannot be rinsed off can also be softened.

[0028] The cable core is then removed from the primary cleaning chamber 304 and passes between multiple wiping belts 323. The motor 317 is started, driving the drive wheel 318 to rotate, which in turn rotates the rotating cover 316. During this process, multiple driven wheels 324 rotate, allowing the wiping belts 323 to rub against the surface of the cable core, wiping away any remaining water-softened stains. The cable core then enters the secondary cleaning chamber 301, where the rinsing process is repeated to remove any remaining stains, further reducing the impact of residual stains on the cable core surface on the subsequent quality of the cable core insulation coating.

[0029] After the cable core passes through the extrusion coating assembly 2, insulation material can be coated onto the surface of the cable core using the extrusion coating assembly 2. This is a common method in the prior art and will not be elaborated on here. After the cable core is coated, it is removed from the extrusion coating assembly 2 and cooled by air over a short distance. Then, it passes under the cooling nozzle 308. At the same time, the water pump 307 delivers water from the primary cleaning chamber 304 and the secondary cleaning chamber 301 to the water supply pipe 306 and sprays it out through the cooling nozzle 308. This process cools and solidifies the coated insulation material. Furthermore, by using water for multiple purposes, the amount of water required during the coating process can be reduced.

[0030] like Figure 8 As shown, a water-absorbing chamber pipe 328 is fixedly connected to the front end of the straight pipe 315. A sponge column 333 is fixedly connected inside the water-absorbing chamber pipe 328, which can absorb most of the water stains first. A ventilation pipe 310 is connected to the upper surface of the water-absorbing chamber pipe 328, and a water-removing chamber pipe 329 is connected to the lower right end of the ventilation pipe 310. A heating and evaporating copper core 331 is fixedly connected inside the water-removing chamber pipe 329. When the cable core passes through the heating and evaporating copper core 331, the residual water stains can be evaporated and removed. Multiple heating rods 330 are fixedly inserted inside the heating and evaporating copper core 331, which can heat the heating and evaporating copper core 331 to a high temperature. An exhaust pipe 334 is connected to the lower surface of the water-absorbing chamber pipe 328, and multiple vent holes 332 are opened on the upper surface of the heating and evaporating copper core 331. A hot air conveying exhaust fan 327 is fixedly connected inside the ventilation pipe 310. The hot air conveying exhaust fan 327 can convey the high-temperature steam and air generated when the water removal chamber pipe 329 evaporates to the inside of the water absorption chamber pipe 328, heat and evaporate the water inside the sponge column 333 and discharge it from the exhaust pipe 334, thereby reducing the water content of the sponge column 333.

[0031] By adopting the above technical solution, after the surface stains on the cable core are treated, the cable core passes through the water absorption chamber 328. The sponge columns 333 inside the water absorption chamber 328 absorb most of the water stains. Subsequently, the cable core passes through the dewatering chamber 329. Simultaneously, the heating rod 330 heats the heating and evaporating copper core 331, keeping it at a high temperature. This allows any remaining water stains to evaporate and be removed as the cable core passes through the heating and evaporating copper core 331, preventing water stains on the cable core surface from adversely affecting the quality of the cable core insulation material. By first removing most of the water and then removing the remaining water, the cleaning speed and effectiveness are accelerated, and the travel distance during the cable core dewatering process is reduced. During the process of cleaning water stains, the high-temperature steam and air generated during the evaporation inside the water removal chamber 329 are transported to the inside of the water absorption chamber 328 by the hot air conveying exhaust fan 327. The high-temperature steam and air can heat and evaporate the water inside the sponge column 333 and discharge it from the exhaust pipe 334, thereby reducing the water content of the sponge column 333 and maintaining the water absorption effect of the sponge column 333.

[0032] Instructions for use: First, use the traction device to pull and move the cable core; Subsequently, the flushing pipe 313, which is connected to an external water source, can deliver water to the primary cleaning chamber 304 and the secondary cleaning chamber 301; Next, the stains on the surface of the cable core are initially rinsed; Subsequently, the cable core passes between multiple wiping strips 323, allowing the wiping strips 323 to wipe away the water-softened stains remaining on the surface of the cable core. Then, the above rinsing operation is repeated in the secondary cleaning chamber 301 to remove the remaining stains. Subsequently, the cable core passes through the water absorption tube 328, and most of the water stains are absorbed by the sponge column 333 inside the water absorption tube 328. Subsequently, the cable core passes through the dewatering chamber pipe 329; At the same time, the heating and evaporating copper core 331 is heated by the heating rod 330; Then, the remaining water stains were evaporated and removed; Next, the high-temperature steam generated during evaporation inside the dewatering chamber pipe 329, along with air, is transported to the interior of the water absorption chamber pipe 328 by the hot air conveying exhaust fan 327. Next, the water inside the sponge column 333 is heated and evaporated by high-temperature steam and air and discharged from the exhaust pipe 334; Next, after the cable core passes through the extrusion coating assembly 2, the surface of the cable core is coated with insulating material through the extrusion coating assembly 2; Subsequently, the cable core is removed from the extrusion coating assembly 2 and cooled by a short distance of air; Next, it passes below the cooling nozzle 308; At the same time, water pump 307 delivers water from primary cleaning chamber 304 and secondary cleaning chamber 301 to water supply pipe 306 and sprays it out through cooling nozzle 308 for cooling.
