Technical Field

[0002] New energy cables are a cluster of special wires and cables customized for the entire new energy industry chain, including photovoltaics, wind power, energy storage, and new energy vehicles. They belong to a sub-category of upgraded power cables. Addressing the extreme environments, high voltage and high current, frequent dynamic loads, and high safety and reliability requirements of new energy scenarios, they have undergone comprehensive upgrades in material selection, structural design, and manufacturing processes. They are the core power carrier in the entire chain of new energy power generation, power transmission, energy storage, and end-user power consumption. Fire-resistant mica tape is an important component in the production process of new energy cables, and the adhesive coating process on the base tape is a crucial step in mica tape production. To address this, a Chinese patent discloses a method for preparing calcined fire-resistant mica tape (application number CN202010865766.1). This patent improves production efficiency by actively applying adhesive through paper penetration, accelerating the bonding time of the adhesive, and solving problems such as powder shedding and poor adhesion through paper-based adhesive application. However, due to the lack of corresponding auxiliary coating structures in the current refractory mica tape base coating process, the coating nozzle and coating roller need to be repeatedly adjusted to ensure uniform adhesive layer distribution during the coating process, which reduces the convenience of the refractory mica tape base coating process.

[0013] A process for preparing fire-resistant mica tape for new energy cables includes the following steps; S1.

At the same time, select the appropriate coating adhesive and add it to the inside of the splicing and storage box.

S4. Drying and testing: The formed mica tape is cured by drying equipment, and the parameters of the cured mica tape are tested by testing equipment. S5. Separate winding: Separate and wind up the qualified mica tape, and store the wound mica tape.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. A passive dynamic coating and gluing mechanism is set up. Through the cooperation of the various components within the passive dynamic coating and gluing mechanism, the gluing process of the mica tape baseband is optimized. By coordinating the gravity of the coating blade and the lifting force of the rectangular support box, extrusion pressure is applied synchronously to the top and bottom of the baseband. The pressure applied to the baseband is adjusted by adjusting the weight of the counterweight and using Pascal's principle. This allows for passive gluing of the baseband by utilizing the physical and chemical properties of the baseband material and the adhesive. After selecting the appropriate baseband and adhesive type, the adhesive can be applied to the top of the baseband at a suitable thickness. At the same time, the baseband is fully impregnated by the adhesive temporarily stored in the splicing storage box, which further improves the quality of the baseband gluing and effectively improves the subsequent processing quality of the mica tape. This effectively avoids the phenomenon of repeated adjustments required when processing different types of mica tape basebands, and effectively improves the ease of use of the mica tape coating equipment. Meanwhile, through the cooperation between the various components inside the pressure regulating tube and the pressure sensor, dynamic micro-adjustment of the external extrusion pressure during the baseband coating process is realized, further improving the quality of baseband coating. At the same time, the structural design of the assembly clamping plate and the external splicing of the coating blade allows the mica tape coating equipment to be quickly assembled and adjusted according to basebands of different sizes during use, improving the ease of operation of the mica tape coating equipment.

[0015] 2. A front-end circulation adjustment mechanism is set up. Through the cooperation between the various components inside the front-end circulation adjustment mechanism, the pretreatment process before baseband coating is optimized. The cooperation between the support bottom roller and the lifting pressure roller clamps the traveling mica baseband, effectively preventing the baseband from shifting during the process. At the same time, the tightly fitted cleaning scraper scrapes and trims the adhesive surface of the baseband, effectively removing protrusions and defects on the adhesive surface of the baseband and improving the subsequent adhesive coating quality of the baseband. Meanwhile, the continuous circulating airflow between the circulating collection box and the blowing side box and the collection side box allows the particulate impurities scraped off by the cleaning scraper to be carried away and collected under the action of the airflow. This effectively prevents the scraped particulate impurities from accumulating on the top of the base belt. At the same time, the active collection of particulate impurities effectively prevents the particulate impurities that fall off the base belt from being randomly scattered into the surrounding air and causing environmental pollution, thereby effectively improving the environmental friendliness of the mica tape preparation equipment.

[0016] In summary, through the coordinated operation of the passive dynamic coating and gluing mechanism and the various components within the front-end circulation adjustment mechanism, and by actively cleaning the substrate to be coated and applying auxiliary pressure during the coating process, the minor defects at the top of the substrate effectively prevent them from affecting the coating quality. Furthermore, by rapidly adjusting the extrusion pressure during the coating process using Pascal's principle, the repeated adjustments required when processing different types of mica tape substrates are avoided, significantly improving the ease of use of the mica tape coating equipment. By improving the coating process of the mica tape substrate, the subsequent processing quality of the mica tape is effectively enhanced. Attached Figure Description

[0020] Example: Figure 1-10 As shown, the present invention provides a technical solution, a fire-resistant mica tape preparation equipment for new energy cables, including a mica tape coating equipment body 1, and protective side blocks 2 are provided on both sides of the mica tape coating equipment body 1. The main body 1 of the mica tape coating equipment is equipped with a passive dynamic coating and gluing mechanism 3 at the top. The passive dynamic coating and gluing mechanism 3 achieves rapid gluing of the mica tape base with the help of a flexible extrusion structure and the physical and chemical properties of the mica tape base and the coating adhesive.

The outer side of the lifting and sliding frame 304 and the inner side of the supporting and limiting knife holder 303 are tightly slidably fitted together. The bottom of the lifting and sliding frame 304 and the top surface of the splicing plate 301 are mutually fitted together. The side end of the lifting sliding frame 304 is fixedly connected to the assembly clip 306. The outer side of the assembly clip 306 is slidably clipped to the splicing glue storage box 307. The top center of the splicing glue storage box 307 is fixedly connected to the glue delivery pipe 308. The input end of the glue delivery pipe 308 is connected to the external glue delivery pump. The bottom of the splicing glue storage box 307 is tightly fitted to the top surface of the assembly clip plate 301. A rectangular liquid storage box 309 is fixedly connected to the inner middle of the main body 1 of the mica tape coating equipment. A rectangular support box 310 is slidably snapped onto the top of the inner side of the rectangular liquid storage box 309. Liquid guide side boxes 311 are fixedly connected to the middle of both sides of the rectangular liquid storage box 309. A sliding rectangular plate 312 is slidably snapped onto the top of the inner side of the liquid guide side box 311. A counterweight 313 is placed at the top middle of the sliding rectangular plate 312. Both the rectangular liquid storage box 309 and the liquid guide side box 311 are filled with hydraulic oil. The rectangular support box 310 has a cavity inside. The bottom of the outer side of the rectangular support box 310 is tightly fitted with the inner wall of the rectangular liquid storage box 309. The outer side of the sliding rectangular plate 312 is tightly fitted with the inner wall of the liquid guide side box 311. In the initial state, the top of the rectangular support box 310 is flush with the bottom of the inner side of the guide narrow groove 302. A protective cover box 314 is slidably engaged at the outer position of the counterweight 313 at the top center of the protective side block 2; Both sides of the rectangular liquid storage box 309 are embedded with pressure regulating horizontal tubes 315. A micro-motion telescopic rod 316 is embedded in the middle of the inner side of the pressure regulating horizontal tube 315. The micro-motion telescopic rod 316 is of the LA16 series. A horizontal sliding block 317 is fixedly connected to the end of the micro-motion telescopic rod 316. The side of the protective cover box 314 and the side of the protective side block 2 are tightly slidably fitted. The micro-motion telescopic rod 316 is powered by an external power source. The outer side of the horizontal sliding block 317 is tightly slidably fitted with the inner wall of the pressure regulating horizontal tube 315. A pressure sensor 318 is embedded at the bottom of the rectangular liquid storage box 309, corresponding to the position on one side of the pressure regulating horizontal pipe 315. The pressure sensor 318 is at the same horizontal height as the pressure regulating horizontal pipe 315. The signal output terminal of the pressure sensor 318 is connected to an external controller, and the micro-motion telescopic rod 316 is controlled by the external controller. Through the cooperation between the various components inside the passive dynamic coating adhesive mechanism 3, the adhesive application process of the mica tape baseband is optimized. By coordinating the gravity of the coating blade 305 and the lifting force of the rectangular lifting box 310, a squeezing force is synchronously applied to the top and bottom of the baseband. The counterweight 313 is adjusted accordingly. The weight is adjusted using Pascal's principle to regulate the pressure applied to the baseband. This allows for passive coating of the baseband using the physical and chemical properties of the baseband material and the adhesive. By selecting the appropriate baseband and adhesive type, the adhesive can be applied to the top of the baseband at a suitable thickness. Simultaneously, the baseband is fully impregnated with adhesive temporarily stored inside the splicing adhesive storage box 307, further improving the quality of the adhesive application and effectively enhancing the subsequent processing quality of the mica tape. This effectively avoids the need for repeated adjustments when processing different types of mica tape basebands, and significantly improves the ease of use of the mica tape coating equipment. Meanwhile, through the cooperation between the internal components of the pressure regulating tube 315 and the pressure sensor 318, dynamic micro-adjustment of the external extrusion pressure during the baseband coating process is realized, further improving the quality of baseband coating. At the same time, the external splicing structure design of the assembly snap-fit ​​plate 301 and the coating blade 305 allows the mica tape coating equipment to be quickly assembled and adjusted according to basebands of different sizes during use, improving the ease of operation of the mica tape coating equipment. The main body 1 of the mica tape coating equipment is equipped with a front-end circulation adjustment mechanism 4 at the front end. The front-end circulation adjustment mechanism 4 is used to adjust the upper surface of the mica tape base tape to be coated with adhesive, so as to ensure the normal progress of the base tape coating process. The front-end circulation adjustment mechanism 4 includes a mounting suspension 401, a supporting bottom roller 402, a limiting sliding seat 403, a sliding guide block 404, a lifting pressure roller 405, a central mounting knife holder 406, a counterweight connecting block 407, a cleaning scraper 408, a circulation collection box 409, a circulation cleaning fan 410, a blowing side pipe 411, a blowing side box 412, a collection side pipe 413, a collection side box 414, a sliding inner box 415, and an intercepting fine mesh 416. A mounting bracket 401 is embedded at the top of one end of the protective side block 2, corresponding to the front end of the mica tape coating equipment body 1. Support rollers 402 are rotatably mounted on both ends of the inner side of the mounting bracket 401. The top of the mounting bracket 401 is fixedly connected to the top position of the support bottom roller 402 at the top position of the mounting bracket 401. A sliding guide block 404 is slidably engaged at the bottom position of the inner side of the sliding guide block 403. A lifting pressure roller 405 is rotatably connected to the middle of one side of the sliding guide block 404 via a rotating shaft. A central mounting blade holder 406 is fixedly connected to the top center of the mounting suspension 401. A counterweight connecting block 407 is slidably engaged with the top inner side of the central mounting blade holder 406. A cleaning scraper 408 is fixedly connected between the two counterweight connecting blocks 407. The outer side of the sliding guide block 404 is slidably attached to the inner wall of the limiting sliding seat 403. The lifting pressure roller 405 and the supporting bottom roller 402 are aligned with each other. The lowest point of the cleaning scraper 408 is located below the highest point of the supporting bottom roller 402, so that the base belt forms a V-shape when passing through the bottom of the two lifting pressure rollers 405 and the bottom of the cleaning scraper 408. A circulation collection box 409 is fixedly connected to the bottom of the mounting bracket 401 at one end of the main body 1 of the mica tape coating equipment. A circulation cleaning fan 410 is embedded in the middle of one side of the circulation collection box 409. A blowing side pipe 411 is fixedly connected to the middle of one end of the circulation cleaning fan 410. A blowing side box 412 is symmetrically fixedly connected to the end of the blowing side pipe 411 at one side of the top of the mounting bracket 401. A collection side tube 413 is fixedly connected to the middle of the other side of the circulation collection box 409, and a collection side box 414 is symmetrically fixedly connected to the end of the collection side tube 413 at the top position of the mounting bracket 401.

The outer side of the sliding inner box 415 is tightly slidably attached to the inner wall of the circulation collection box 409. Through the cooperation between the components inside the front circulation adjustment mechanism 4, the pretreatment process before baseband coating is optimized. The mica baseband is clamped by the cooperation between the support bottom roller 402 and the lifting pressure roller 405, which effectively prevents the baseband from shifting during the process. At the same time, the cleaning scraper 408 is tightly attached to the adhesive surface of the baseband to scrape and repair, effectively removing the protruding defects on the adhesive surface of the baseband and improving the subsequent coating quality of the baseband. Meanwhile, the continuous circulating airflow between the circulating collection box 409 and the blowing side box 412 and the collecting side box 414 causes the scraped particulate impurities to be carried away and collected by the airflow, thereby effectively preventing the scraped particulate impurities from accumulating on the top of the base belt. At the same time, the active collection of particulate impurities effectively prevents the particulate impurities detached from the base belt from randomly spilling into the surrounding air and causing environmental pollution, thereby effectively improving the environmental friendliness of the mica tape preparation equipment.

[0021] like Figure 11 As shown, a manufacturing process for fire-resistant mica tape for new energy cables includes the following steps: S1. Loading and installation: Select the appropriate mica tape base and composite reinforcing material and install them onto the mica tape processing equipment. At the same time, select the appropriate coating adhesive and add it to the splicing and storage box 307. S2, Material conveying and gluing: The coating adhesive inside the splicing glue storage box 307 is evenly applied to the top of the base belt through the various components on the top of the main body 1 of the mica tape coating equipment; S3. Composite molding: Composite materials and mica tape base are assembled together through composite assembly components, and the materials are extruded and molded using corresponding extrusion equipment. S4. Drying and testing: The formed mica tape is cured by drying equipment, and the parameters of the cured mica tape are tested by testing equipment. S5. Separate winding: Separate and wind up the qualified mica tape, and store the wound mica tape.

[0022] The working principle and usage process of this invention: In practical applications, when it is necessary to apply adhesive to the mica tape baseband using a mica tape coating equipment, the adhesive coating surface of the baseband needs to be treated first. The components are installed on the side of the protective side block 2 by the mounting bracket 401, and the lifting pressure roller 405 is installed on the top of the support bottom roller 402 by the limiting sliding seat 403 in conjunction with the sliding guide block 404. The fixed support bottom roller 402 and the lifting pressure roller 405 can be raised and lowered to clamp and flatten the baseband in motion, so as to ensure that the baseband can remain stable during the motion. Then, the cleaning scraper 408 is installed on the top of the moving baseband through the central mounting blade holder 406 and the counterweight connecting block 407. The weight of the counterweight connecting block 407 makes the cutting edge of the cleaning scraper 408 fit tightly with the top surface of the baseband. When the baseband moves past the bottom of the cleaning scraper 408, the cleaning scraper 408 continuously scrapes the top of the baseband to remove burrs and abnormal protrusions on the top of the baseband, so as to prevent abnormal protrusions on the baseband from affecting the normal progress of the adhesive coating process. While the cleaning scraper 408 is scraping the baseband, a continuous blowing airflow is generated by the circulating cleaning fan 410 on the side of the circulating collection box 409. The continuous blowing airflow is then introduced into the blowing side box 412 through the blowing side pipe 411, and the blowing airflow is continuously blown horizontally through the blowing side box 412 to clean the side of the cleaning scraper 408, so that the protrusions and burrs scraped off the top of the baseband are separated from the top of the baseband. Next, the airflow with protrusions and burrs is collected by the continuous negative pressure on the side of the collection side box 414, and the mixed airflow is introduced into the circulation collection box 409 through the collection side pipe 413. During the process of the mixed airflow flowing through the circulation collection box 409, the burrs and protrusions in the mixed airflow are intercepted and collected by the cooperation between the sliding inner box 415 and the intercepting fine mesh 416, thereby realizing the cleaning and collection process of the baseband. When it is necessary to formally coat the top of the mica tape base, select the appropriate model of the assembly snap-fit ​​plate 301 according to the width and thickness of the base, and guide the base to pass through the guide narrow groove 302. At the same time, according to the material of the base and the physical and chemical properties of the coating adhesive, select the appropriate weight of the counterweight 313 and place it on the top of the sliding rectangular plate 312. The counterweight 313 is protected by the snap-fit ​​protective cover box 314 to prevent the counterweight 313 from being affected by the external environment during the operation of the equipment. The baseband is driven forward along the guide narrow groove 302 by the traction device at the end of the baseband. While the baseband moves forward at a constant speed, the glue is introduced into the splicing glue storage box 307 through the glue delivery top pipe 308 for temporary storage. This allows the baseband to be fully wetted as it travels through the bottom of the splicing glue storage box 307. At the same time, the adhesive itself and the continuously moving baseband seal the gap between the bottom of the splicing glue storage box 307 and the guide narrow groove 302, preventing the glue inside the splicing glue storage box 307 from overflowing from the bottom. After the baseband is soaked in adhesive, it advances and passes the bottom of the coating blade 305. The coating blade 305 is guided by the cooperation between the support and limiting blade holder 303 and the lifting sliding frame 304, ensuring that the bottom of the coating blade 305 is flush with the top surface of the assembly clamping plate 301. Simultaneously, the weight 313 on the top of the sliding rectangular plate 312 is converted into lift force of the rectangular lifting box 310 through the hydraulic oil inside the rectangular liquid storage box 309 and the rectangular lifting box 310. The lift force of the rectangular lifting box 310 is always less than the sum of the weights of the lifting sliding frame 304 and the coating blade 305. This lift force of the rectangular lifting box 310 applies pressure to the bottom of the baseband. Continuous pressure is applied to maintain a suitable interaction force between the baseband and the coating blade 305. Due to the adhesive's own viscosity, there is a scraping resistance between the adhesive coating on the baseband and the coating blade 305. Therefore, after the adhesive on the top of the baseband is scraped by the coating blade 305, an adhesive coating of the target thickness can be left. The thickness of the adhesive layer on the top of the baseband can be controlled by controlling the weight of the counterweight 313. When selecting a glass fiber baseband, an adhesive with a viscosity of 1500 cps, and a 250-gram counterweight 313, the thickness of the adhesive layer on the top of the baseband is always kept within the range of 8-18 μm, which improves the convenience of controlling the thickness of the adhesive layer on the top of the baseband. When fine-tuning of the internal pressure of the rectangular liquid storage box 309 is required, the pressure sensor 318 monitors the internal pressure of the rectangular liquid storage box 309 in real time. When the internal pressure of the rectangular liquid storage box 309 drops, the micro-motion telescopic rod 316 inside the pressure regulating horizontal tube 315 is extended by the external controller. During the extension of the micro-motion telescopic rod 316, the horizontal sliding block 317 is moved horizontally. During the movement of the horizontal sliding block 317, the internal cavity of the rectangular liquid storage box 309 is compressed, thereby realizing the control of the internal pressure of the rectangular liquid storage box 309. The thickness of the adhesive layer on the top of the baseband is indirectly adjusted by adjusting the internal pressure of the rectangular liquid storage box 309.
