Description

Technical Field

[0001] This invention relates to the field of wire and cable manufacturing technology, specifically to a flame-retardant and fire-resistant wire and cable manufacturing apparatus and its manufacturing process. Background Technology

[0002] As the core carrier of power transmission and signal transmission, wires and cables are widely used in many key fields such as construction engineering, industrial production, transportation and new energy. Their safety performance is directly related to the stable operation of various facilities and the safety of people and property. In emergency scenarios such as fires, ordinary wires and cables are flammable and release a large amount of toxic and harmful gases when burning, producing molten drips. This can not only quickly cause circuit interruption, but also aggravate the spread of fire, hinder the evacuation of people, and cause secondary disasters. Therefore, the optimization and upgrading of wire and cable manufacturing technology has always been a key focus of the industry.

[0003] Existing wire and cable manufacturing equipment often results in the adhesion of impurities such as dust, oil, and metal shavings generated during production and storage to the surface of the wire conductors. Traditional manufacturing equipment lacks an efficient pretreatment process, leading to insufficient adhesion between the subsequent flame-retardant and fire-resistant coating and the conductor surface. Under long-term use, bending, or high-temperature environments, peeling and cracking are likely to occur, seriously affecting the flame-retardant and fire-resistant performance and service life of the wires and cables. Furthermore, some equipment only uses natural cooling or water cooling, which has low cooling efficiency and slow coating curing speed, making it prone to problems such as sagging and deformation. On the other hand, high-temperature curing alone may cause stress cracks to form inside the coating, further affecting product quality.

[0004] In light of the above issues, it becomes clear that existing flame-retardant and fire-resistant wire and cable manufacturing equipment on the market cannot simultaneously avoid the problems mentioned above during use. Even if these problems can be solved, they require the assistance of external tools, thus failing to achieve the desired results. Therefore, we propose a flame-retardant and fire-resistant wire and cable manufacturing equipment and its manufacturing process. Summary of the Invention

[0008] Preferably, a reinforcing plate is fixedly connected to the outer surface of each L-shaped fixing plate, and the side of each of the two reinforcing plates that are close to each other is fixedly connected to the outer surface of the collection box.

[0009] Preferably, each of the reinforcing plates has two fixing bolts threaded to its inner wall, and the outer surface of each set of fixing bolts is threaded to the inner wall of the collection box.

[0010] Preferably, a support frame is fixedly connected to the outer surface of the first water pump, and the outer surface of the support frame is fixedly connected to the upper surface of the cleaning tank.

[0011] Preferably, the coating unit includes a coating liquid storage tank, the outer surface of which is fixedly connected to a delivery pump, the output end of which is fixedly connected to a coating mold, the outer surface of which is fixedly connected to two limiting frames, the bottom surfaces of which are fixedly connected to the upper surface of the base plate, the inner wall of which has several identical coating liquid inlets, and the outer surface of which is fixedly connected to a support block, the outer surface of which is fixedly connected to the upper surface of the base plate.

[0012] Preferably, the cooling mechanism includes a support platform, a curing chamber is fixedly connected to the upper surface of the support platform, a temperature sensor, an ultraviolet lamp and four heating rods are fixedly connected to the inner wall of the curing chamber, a cooling box is fixedly connected to the upper surface of the base plate, a second water pump is fixedly connected to the outer surface of the cooling box, a delivery pipe is fixedly connected to the output end of the second water pump, a plurality of identical water mist nozzles are fixedly connected to the outer surface of the delivery pipe, and the outer surface of the delivery pipe is fixedly connected to the inner wall of the cooling box.

[0013] Preferably, a limiting plate is fixedly connected to the outer surface of the second water pump, and the outer surface of the limiting plate is fixedly connected to the outer surface of the cooling box.

[0014] Preferably, the outer surface of the curing chamber is fixedly connected to two fixed inclined plates, and the bottom surface of each fixed inclined plate is fixedly connected to the upper surface of the support platform.

[0015] A manufacturing process for a flame-retardant and fire-resistant wire and cable manufacturing apparatus includes the following steps: S1: First, check the cleaning fluid level in the water tank to ensure it meets production requirements. Start the stepper motor to drive the reel through the bearing. Adjust the reel speed to match the production rate. Turn on the electric heater to preheat the drying chamber. Keep the exhaust vent clear to remove moisture. Pass one end of the conductor to be treated between the two sets of reels and feed it into the cleaning chamber and drying chamber in sequence, finally aligning it with the inlet of the subsequent coating unit. Start the first water pump. The pump body, fixed by the support frame, pressurizes and delivers the cleaning fluid in the water tank to the water storage pipe. Several water nozzles form a uniform water mist to coat the surface of the conductor passing through the cleaning chamber. The entire process involves rinsing to remove dust, oil, metal shavings, and other impurities. The waste liquid flows into the collection tank along the inner wall of the cleaning tank and is filtered through a filter plate to remove impurities, facilitating subsequent waste liquid recycling. The L-shaped fixing plate and the reinforcing plate are secured with bolts to ensure a stable connection between the collection tank and the cleaning tank, preventing vibration and displacement during rinsing. After cleaning, the conductor enters a preheated drying chamber where two electric heating fans symmetrically blow hot air to quickly dry the conductor surface, preventing residual moisture from affecting the adhesion of the coating layer. The dried conductor is then pulled by a reel to the coating unit, ensuring that the conductor surface is free of water droplets and oil before proceeding to the next process. S: Next, inject the prepared flame-retardant and fire-resistant coating liquid into the coating liquid storage tank, ensuring that the coating liquid is free of sediment and lumps. Check the connection pipeline between the delivery pump and the coating mold to ensure good sealing and no leakage. Adjust the output pressure of the delivery pump according to the target coating thickness of the wire and cable. Fix the position of the coating mold with the limit frame to ensure that the center of the mold is aligned with the conductor delivery path to avoid coating layer eccentricity. Start the delivery pump. After the coating liquid in the storage tank is pressurized by the pump body, it is injected into the mold cavity simultaneously through several coating liquid inlets on the inner wall of the coating mold. The conductor passes through the coating mold at a uniform speed under the traction of the stepper motor. The coating liquid forms a stable liquid film in the mold cavity, which evenly wraps the conductor surface to achieve all-round coating without dead corners. The support block ensures the stability of the delivery pump during operation and avoids pressure fluctuations that cause uneven coating thickness. S: Restart the heating rod inside the curing chamber, monitor the temperature inside the chamber in real time through the temperature sensor, turn on the ultraviolet lamp, and preheat for five to ten minutes to ensure the stability of the light source. Fix the inclined plate to enhance the connection stability between the curing chamber and the support platform to avoid deformation under high temperature. The coated conductor enters the curing chamber. Under the combined action of high temperature and ultraviolet light, the coating layer undergoes a rapid cross-linking reaction and is initially cured and formed. The temperature sensor provides real-time temperature data to ensure a stable curing environment. The cured conductor is pulled into the cooling chamber, and the second water pump is started. The pump body, fixed by the limit plate, delivers the cooling water source to the delivery pipe. Through several water mist nozzles, a fine water mist is formed to uniformly cool the surface of the conductor, so that the temperature of the coating layer drops to room temperature quickly, completing the final shaping. The cooled wire and cable are pulled out by the end reel and can be wound up for subsequent processing.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention incorporates a pretreatment unit that washes away dust and impurities from the surface of the wire conductor. Combined with an electric heater in the drying chamber, this thoroughly removes surface dust, oil, and metal shavings, avoiding the problem of insufficient coating adhesion caused by residual impurities in traditional devices.

[0017] This invention, by setting up a coating unit and utilizing a multi-inlet synchronous feeding design, allows the flame-retardant and fire-resistant coating liquid in the coating liquid storage tank to be pressurized by a delivery pump and then uniformly injected into the mold cavity through several coating liquid inlets on the inner wall of the coating mold. This design avoids the problem of uneven coating thickness caused by single-inlet feeding, ensuring that the coating liquid forms a uniform and complete flame-retardant and fire-resistant layer on the conductor surface, significantly improving the flame-retardant and fire-resistant performance of wires and cables.

[0018] This invention, by setting up a cooling mechanism, can cool and reduce the temperature of wires and cables. By setting up a pretreatment unit, a coating unit, and a cooling mechanism, it can realize continuous production from conductor pretreatment, coating to curing and cooling, which greatly shortens the production cycle. Compared with the traditional segmented production, it improves efficiency and reduces the cost of manual intervention and material loss in the production process. Attached Figure Description

With the help of the electric heating fans 2118 on the drying oven 2117, the surface dust, oil and metal shavings and other impurities can be thoroughly removed, avoiding the problem of insufficient coating adhesion caused by impurity residue in traditional devices.

[0024] Please see Figure 3 Each L-shaped fixing plate 2107 has a reinforcing plate 2109 fixedly connected to its outer surface. The two reinforcing plates 2109 are fixedly connected to the outer surface of the collection box 2106 on their side closest to each other. The reinforcing plates 2109 can reinforce the L-shaped fixing plate 2107 and the collection box 2106 to prevent them from shifting or becoming unstable during use.

[0025] Please see Figure 3 Each reinforcing plate 2109 has two fixing bolts 2110 threadedly connected to its inner wall.

[0027] The specific implementation method of this embodiment is as follows: First, check the cleaning fluid storage in the water tank 2105 to ensure that the liquid level meets the production requirements. Start the stepper motor 2101, which drives the reel 2104 to rotate through the bearing 2103. Adjust the speed of the reel 2104 to match the production rate. Turn on the electric heater 2118 to preheat the internal temperature of the drying chamber 2117. Keep the exhaust vent 2119 unobstructed to remove moisture. Pass one end of the conductor of the wire to be treated between the two sets of reels 2104 and send it into the cleaning chamber 2108 and the drying chamber 2117 in sequence. Finally, align it with the feed port of the subsequent coating unit 22. Start the first water pump 2112. The pump body fixed by the support frame 2113 pressurizes and delivers the cleaning fluid in the water tank 2105 to the water storage pipe 2114. The fluid is then sprayed through several water nozzles 2116 to form a uniform water solution. The mist thoroughly rinses the conductor surface passing through the cleaning tank 2108, removing dust, oil, metal shavings, and other impurities. The waste liquid after cleaning flows along the inner wall of the cleaning tank 2108 into the collection tank 2106, where it is filtered by the filter plate 2111 to remove impurities, facilitating subsequent waste liquid recycling. The L-shaped fixing plate 2107 and the reinforcing plate 2109 are secured by fixing bolts 2110 to ensure a stable connection between the collection tank and the cleaning tank 2108, preventing vibration and displacement during rinsing. The cleaned conductor enters the preheated drying chamber 2117, where two electric heating fans 2118 symmetrically blow hot air to achieve rapid drying of the conductor surface, preventing residual moisture from affecting the adhesion of the coating layer. The dried conductor is then pulled by the reel 2104 to the coating unit 22, ensuring that the conductor surface is free of water droplets and oil before proceeding to the next process.

[0029] As a further definition of the coating mechanism 2 of the present invention, the coating unit 22 includes a coating liquid storage tank 2201. A delivery pump 2204 is fixedly connected to the outer surface of the coating liquid storage tank 2201. The output end of the delivery pump 2204 is fixedly connected to a coating mold 2203. Two limiting frames 2202 are fixedly connected to the outer surface of the coating mold 2203.

Several identical coating liquid inlets 2206 are provided on the inner wall of the coating mold 2203. A support block 220 is fixedly connected to the outer surface of the delivery pump 2204. 5. The outer surface of the support block 2205 is fixedly connected to the upper surface of the base plate 1.

[0030] The specific implementation method of this embodiment is as follows: First, the prepared flame-retardant and fire-resistant coating liquid is injected into the coating liquid storage tank 2201 to ensure that the coating liquid is free of sediment and lumps. The connection pipeline between the delivery pump 2204 and the coating mold 2203 is checked to ensure that it is well sealed and leak-free. The output pressure of the delivery pump 2204 is adjusted according to the target coating thickness of the wire and cable. The position of the coating mold 2203 is fixed by the limit frame 2202 to ensure that the center of the mold is aligned with the conductor delivery path to avoid the coating layer being eccentric. The delivery pump 2204 is started. After the coating liquid in the coating liquid storage tank 2201 is pressurized by the pump body, it is injected into the mold cavity simultaneously through several coating liquid inlets 2206 on the inner wall of the coating mold 2203. The conductor passes through the coating mold 2203 at a uniform speed under the traction of the stepper motor 2101. The coating liquid forms a stable liquid film in the mold cavity, which evenly wraps the surface of the conductor to achieve all-round coating without dead angles. The support block 2205 ensures the stability of the delivery pump 2204 during operation and avoids uneven coating thickness caused by pressure fluctuations.

The bottom surface of each fixed inclined plate 304 is fixedly connected to the upper surface of the support platform 302. The fixed inclined plates 304 can fix and support the position of the curing box 303, thereby enhancing the stability of the device.

[0035] The specific implementation method of this embodiment is as follows: First, the heating rod 306 in the curing chamber 303 is started, and the temperature inside the chamber is monitored in real time by the temperature sensor 305. The ultraviolet lamp tube 307 is turned on and preheated for five to ten minutes to ensure the stability of the light source. The fixed inclined plate 304 enhances the connection stability between the curing chamber 303 and the support platform 302 to avoid deformation under high temperature. The coated conductor enters the curing chamber 303. Under the synergistic effect of high temperature and ultraviolet light, the coating layer undergoes a rapid cross-linking reaction and is initially cured and formed.

Start the first water pump 2112, which pressurizes the cleaning fluid in the water tank 2105 and delivers it to the water storage pipe 2114 via the pump body fixed by the support frame 2113. The fluid is then sprayed through several water nozzles 2116 to form a uniform water mist, which is then sprayed onto the wire passing through the cleaning tank 2105. The conductor surface of the cleaning box 2108 is thoroughly rinsed to remove dust, oil, metal shavings and other impurities. The waste liquid after cleaning flows into the collection box 2106 along the inner wall of the cleaning box 2108.

The support block 2205 ensures the stability of the delivery pump 2204 during operation and avoids pressure fluctuations that cause uneven coating thickness. S3: Restart the heating rod 306 inside the curing chamber 303. The temperature inside the chamber is monitored in real time by the temperature sensor 305. Turn on the ultraviolet lamp 307 and preheat for five to ten minutes to ensure the stability of the light source. Fix the inclined plate 304 to enhance the connection stability between the curing chamber 303 and the support platform 302 to avoid deformation under high temperature.

Under the synergistic effect of high temperature and ultraviolet light, the coating layer undergoes a rapid cross-linking reaction and is initially cured. The temperature sensor 305 provides real-time temperature data to ensure a stable curing environment. The cured conductor is pulled into the cooling chamber 301. Start the second water pump 310. The pump body, fixed by the limiting plate 311, delivers cooling water to the conveying pipe 308.

10. The manufacturing process of a flame-retardant and fire-resistant wire and cable manufacturing apparatus according to any one of claims 1-9, characterized in that: Specifically, the following steps are included: S1: First, check the cleaning fluid level in the water tank (2105) to ensure that the level meets production requirements. Start the stepper motor (2101) and drive the reel (2104) to rotate through the bearing (2103). Adjust the speed of the reel (2104) to match the production rate. Turn on the electric heater (2118) to preheat the temperature inside the drying box (2117). Keep the exhaust vent (2119) clear to remove moisture. Pass one end of the conductor to be treated between the two sets of reels (2104) and send it into the cleaning box (2108) and drying box (2117) in sequence. Finally, align it with the feed inlet of the subsequent coating unit (22). Start the first water pump (2112). Through the pump body fixed by the support frame (2113), pressurize and deliver the cleaning fluid in the water tank (2105) to the water storage pipe (2114). Form a uniform water mist through several water nozzles (2116) to... The conductor surface is thoroughly rinsed through the cleaning tank (2108) to remove dust, oil, metal shavings and other impurities. The waste liquid after cleaning flows into the collection tank (2106) along the inner wall of the cleaning tank (2108). It is filtered by the filter plate (2111) to remove impurities, which facilitates subsequent waste liquid recycling. The L-shaped fixing plate (2107) and the reinforcing plate (2109) are secured by fixing bolts (2110) to ensure that the collection tank (2106) and the cleaning tank (2108) are firmly connected to avoid vibration and displacement during rinsing. The cleaned conductor enters the preheated drying box (2117). Two electric heating fans (2118) blow hot air symmetrically to achieve rapid drying of the conductor surface and avoid residual moisture affecting the adhesion of the coating layer. The dried conductor is pulled by the reel (2104) to the coating unit (22). Only after ensuring that there are no water droplets or oil stains on the conductor surface can it enter the next process. S2: Next, inject the prepared flame-retardant and fire-resistant coating liquid into the coating liquid storage tank (2201), ensuring that the coating liquid is free of sediment and lumps. Check the connection pipeline between the delivery pump (2204) and the coating mold (2203) to ensure good sealing and no leakage. Adjust the output pressure of the delivery pump (2204) according to the target coating thickness of the wire and cable. Fix the position of the coating mold (2203) by the limit bracket (2202) to ensure that the center of the mold is aligned with the conductor delivery path to avoid coating layer eccentricity. Start the delivery pump (2204). 4) The coating liquid in the coating liquid storage tank (2201) is pressurized by the pump body and then injected into the mold cavity through several coating liquid inlets (2206) on the inner wall of the coating mold (2203). The conductor passes through the coating mold (2203) at a uniform speed under the traction of the stepper motor (2101). The coating liquid forms a stable liquid film in the mold cavity and evenly wraps the surface of the conductor, achieving all-round coating without dead angles. The support block (2205) ensures the stability of the delivery pump (2204) during operation and avoids uneven coating thickness caused by pressure fluctuations. S3: Restart the heating rod (306) in the curing chamber (303), monitor the temperature inside the chamber in real time through the temperature sensor (305), turn on the ultraviolet lamp tube (307), preheat for five to ten minutes to ensure the stability of the light source, fix the inclined plate (304) to enhance the connection stability between the curing chamber (303) and the support platform (302) to avoid deformation under high temperature, the coated conductor enters the curing chamber (303), under the synergistic effect of high temperature and ultraviolet light, the coating layer quickly undergoes cross-linking reaction and is initially cured and formed, the temperature sensor (305) provides real-time feedback of temperature data to ensure the stability of the curing environment, the cured conductor is pulled into the cooling chamber (301), the second water pump (310) is started, the pump body fixed by the limit plate (311) delivers the cooling water source to the delivery pipe (308), and a fine water mist is formed through several water mist nozzles (309) to uniformly cool the surface of the conductor, so that the temperature of the coating layer drops to room temperature quickly and the final shaping is completed, the cooled wire and cable is pulled out by the end reel (2104) and can be wound up for subsequent processing.
