Description

Technical Field

[0001] This invention relates to the field of Joule heating equipment technology, and more specifically to a roll-to-roll continuous Joule heating equipment. Background Technology

[0002] In the field of advanced materials preparation, the Joule heating principle, with its unique advantage of "materials reaching extremely high temperatures in a very short time," has become a key technological means for synthesizing high-end functional materials. The rapid heating process achieved based on this principle allows for precise control of the microstructure of materials, enabling the efficient preparation of nanoscale particles, single-atom catalysts, high-entropy alloys, and other materials with special properties. These materials are widely used in core areas such as catalytic reactions, energy storage, and high-end manufacturing, and are of great significance in promoting the technological upgrading of related industries. Currently, while existing Joule heating mechanisms in the industry can utilize this principle to complete basic heating experiments, they suffer from the following limitations: existing devices typically have only a single heating station, and due to structural design constraints, the amount of material that can be processed in a single heating cycle is extremely small, while the heating cycle is relatively long. This "single-station, small-batch, long-cycle" characteristic means that it can only meet the needs of preparing and testing small numbers of samples in the laboratory. For systematic experiments requiring large-scale sample comparisons, or for industrial-scale mass production scenarios, the efficiency and capacity of existing Joule heating mechanisms are completely incompatible, becoming a core pain point restricting the large-scale application of Joule heating technology. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a roll-to-roll continuous Joule heating device, which solves the problems mentioned in the background art.

The separators divide the area above the liquid guiding sloping plate into a specified number of coating zones and agitate the liquid within the coating zones. When the separators are retracted into the storage component, the storage component scrapes off any residual liquid from the sides of the separators. A gap is left between the storage component and the liquid guiding sloping plate. The coating assembly includes: a drain gap; a liquid receiving component installed at the bottom inside the coating shield to collect residual liquid scraped off; a liquid guiding slant, a storage component, and both ends of the liquid receiving component fixed inside the coating shield; a liquid guiding component installed at the top inside the coating shield and above the coating area to guide liquid into the coating area; a Joule heating component installed at the output end of the coating assembly to rapidly heat the substrate to the specified experimental value using the Joule heating principle; a spraying assembly installed at the top of the Joule heating assembly; when the spraying assembly is working, the end of the liquid receiving component blocks the coating area of ​​the liquid guiding slant to form a liquid collection pool, and the input end of the spraying assembly connects to the coating area above the liquid guiding slant; and a substrate winding assembly installed at the output end of the Joule heating assembly and at the other end inside the heating chamber.

[0005] Furthermore, the substrate release assembly includes an unwinding air shaft, an unwinding side plate, a linear guide rail, a correction actuator motor, and a magnetic powder brake.

The substrate release assembly also includes floating roller side plates. Two sets of floating roller side plates are located at the output end of the unwinding side plate. An inclined floating groove is opened inside the floating roller side plate. A slider is installed inside the floating groove. A floating roller is rotatably installed between the two sets of sliders. A first guide roller is installed above one side of the floating roller and a second guide roller is installed below the other side. The first guide roller and the second guide roller are rotatably installed between the two sets of floating roller side plates. The slider and the floating roller side plate are connected by a tension spring.

[0006] Furthermore, the coating guide roller assembly includes coating side plates, with a first coating roller and a second coating roller installed above the two coating side plates, and a coating gap between the first coating roller and the second coating roller; a third guide roller is installed on one side of the bottom of the second coating roller, and a fourth guide roller is installed below the third guide roller.

[0007] Furthermore, the liquid guiding inclined plate has T-shaped fixed side frames at both ends. The inner end of the fixed side frame is provided with a swing drive component, and the outer end is provided with a clamping component. The swing drive component includes a longitudinal toothed plate, a longitudinal guide rail, a first drive rod, and a longitudinal hanging plate. The two ends of the longitudinal hanging plate are fixedly connected to the top inner end of the fixed side frame. The bottom end of the longitudinal hanging plate is provided with a longitudinal guide rail. The longitudinal toothed plate is slidably installed on the side of the longitudinal guide rail. The surface of the longitudinal toothed plate is fixedly provided with an abutment strip. The first drive rod is provided on the surface of the longitudinal guide rail and its output end is connected to the abutment strip. The first drive rod is used to drive the longitudinal toothed plate to reciprocate along the longitudinal guide rail. The mounting component includes a base plate, with a snap-fit ​​strip on the top of the base plate. The snap-fit ​​strip has multiple sets of snap-fit ​​slots inside. The two ends of the base plate are fixedly connected to the top outer ends of the fixed side frame. The base plate and the longitudinal guide rail are both arranged parallel to each other above the liquid guiding inclined plate.

[0008] Furthermore, the separator includes a central partition and side partitions. The structure of the central partition is the same as that of the side partitions. Two sets of agitating components are symmetrically arranged at one end of the central partition, and a set of agitating components is installed at one end of the inner side of the side partition.

[0009] The partition includes a main body, the inner end of which has a notch adapted to the second coating roller, and the top of the outer end of the main body has a vertical box, a card plate is slidably installed on the inner side of the vertical box, and a spring rod is installed inside the vertical box; the area between the two main bodies is the coating area. The stirring component includes an extension plate and a stirring plate. One end of the extension plate is vertically fixed to the side of the main body. The top of the stirring plate is rotatably connected to the extension plate, and a driven gear is provided at the rotatable connection. The driven gear is located on the top of the extension plate. The top of the extension plate is provided with an elastic claw. The elastic claw cooperates to elastically engage the driven gear.

The liquid receiving box is located at the bottom of the liquid guiding inclined plate, and the collecting end of the liquid receiving box is placed at the bottom of the drain gap. When the spraying assembly is working, the coating protective cover drives the coating assembly and the liquid receiving assembly to move as a whole, so that the liquid guiding inclined plate is disengaged from the second coating roller, and the sealing plate rotates upward to seal the coating area.

[0011] Furthermore, the coating protective cover includes two sets of movable side plates and a cover. The inner wall of the heating box is symmetrically provided with displacement guide rails, and the outer wall of the movable side plate is provided with a movable block.

When the separator is put into the tray, the main body and the stirring plate are respectively put into a set of positioning slots. The V-shaped groove cleans the sides of the main body and the stirring plate, and the extension plate is placed above the positioning plate.

[0013] Furthermore, the liquid guiding assembly includes three sets of liquid filling main pipes, each set of liquid filling main pipes having an inner end connected to a set of liquid filling bellows and an outer end connected to a set of liquid filling pumps, and the three sets of liquid filling pumps are installed on the liquid storage tank.

[0014] Furthermore, the Joule heating assembly includes heating side plates, with two sets of water-cooled guide rollers and water-cooled electrode rollers symmetrically arranged between the two sets of heating side plates. The water-cooled electrode rollers are located above the inner side of the water-cooled guide rollers, and the substrate passes horizontally above the two sets of water-cooled electrode rollers.

Bearings with seats are installed at both ends of the tension measuring roller, and a tension sensor is installed at the bottom of each set of bearings. Second safety clamps are installed at both ends of the winding air shaft, and the bottom of the second safety clamps is installed on the winding side plates. One end of the winding air shaft is connected to a servo motor via a synchronous belt.

[0015] This invention provides a roll-to-roll continuous Joule heating apparatus. Compared with the prior art, it has the following advantages: 1. The substrate release assembly, coating / spraying assembly, Joule heating assembly, and winding assembly are sequentially connected. The Joule heating assembly utilizes Joule heat to rapidly dry the coating layer, achieving continuous operation of "substrate release - coating / spraying - heating and drying - winding," which greatly improves the efficiency of experiments or production. Furthermore, the equipment has automatic web guiding control, closed-loop tension control, closed-loop linear speed control, and a closed-loop temperature control system, ensuring stable and reliable continuous operation.

[0016] 2. The coating assembly enables seamless switching between coating and spraying processes, adapting to diverse substrate processing needs: The coating protective cover can slide laterally along the displacement guide rail inside the heating box. When processing substrates that need to be coated, such as conductive carbon cloth, the coating protective cover slides onto the substrate path, and the liquid guiding inclined plate connects with the coating gap of the coating guide roller group. The slurry is coated onto the substrate surface through the coating area. When processing substrates such as nickel mesh that require spraying, the coating protective cover slides outward to detach from the substrate path, avoiding interference between the liquid guiding slant and the substrate, and driving the internal coating components (liquid guiding slant, coating guide roller group, etc.) to adjust their overall position; the sealing plate of the liquid receiving component rotates upward and is embedded in the notch of the separator to seal the outlet end of the coating area, so that the coating area is transformed into a closed liquid collection pool, providing a stable slurry storage space for the spraying components; In this way, the two coating methods share a set of liquid filling and storage structures, eliminating the need for two sets of liquid filling and storage structures, thus reducing costs. At the same time, based on the feature that the liquid guiding inclined plate can be divided into sections by the separator, both coating and spraying processes can be carried out in sections. Furthermore, based on the feature that the separator can agitate the liquid, the slurry flow is smoother during coating and spraying processes, reducing sedimentation and clogging. 3. The partitioned coating structure supports multiple control experiments, improving experimental efficiency and data reliability: The top of the liquid guiding sloping plate is divided into coating zones by a combination of side and central partitions. Two sets of side partitions can form one coating zone (for a single type of slurry), adding one set of central partitions creates two coating zones, and adding two sets of central partitions creates three coating zones, accommodating the simultaneous processing needs of 1-3 different slurries. The multiple main liquid supply pipes of the liquid guiding assembly correspond to different coating zones, allowing for the separate delivery of slurries with different formulations. This ensures independent slurry supply to each zone, preventing cross-contamination and providing a precise basis for variable control in control experiments.

[0017] A single batch of processing can complete the simultaneous coating and heating drying of multiple slurries, directly obtaining performance data (such as drying rate, adhesion strength, etc.) of different slurries under the same heating conditions, without the need for repeated experiments in batches; 4. The storage component can store unused dividers, making it easy to access different types of dividers. When the dividers are stored, the storage component can also clean any residual liquid on the sides of the dividers. 5. The liquid receiving component collects residual waste liquid from each area, preventing contamination from mixing different slurries, ensuring the accuracy and comparability of control data, and reducing raw material waste and experimental costs; the liquid receiving component can also seal the ends of the coating area. 6. Whether in the open coating area during application or the closed collection tank during spraying, the separator can continuously agitate the slurry. For slurries with high solids content or easy settling, the rotation of the agitator plate can disrupt the particle settling tendency, keeping the slurry in a uniformly dispersed state and avoiding "local thick / thin slurry" during coating or "nozzle clogging / uneven atomization" during spraying. Furthermore, the agitation intensity can be adjusted by the moving frequency of the longitudinal toothed plate to adapt to the agitation requirements of slurries with different viscosities, ensuring that the slurry thickness on the substrate surface is uniform and the composition is consistent after coating / spraying, providing a fundamental guarantee for the performance stability after subsequent Joule heating and drying.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0021] Example To address the technical problems in the background art, the following roll-to-roll continuous Joule heating device is provided: Combination Figures 1-15 As shown, the present invention provides a roll-to-roll continuous Joule heating device, including a heating box 100; The substrate release assembly 200 is disposed at one end inside the heating chamber 100; The coating protective cover 300 is laterally slidably disposed inside the heating chamber 100 and located at the output end of the substrate release assembly 200; A coating assembly 400 is installed inside a coating protective cover 300. The coating assembly 400 includes a coating guide roller group 410. A liquid guiding sloping plate 420 is provided at the coating gap of the coating guide roller group 410. A swing drive component 430 is installed at the inner top end of the liquid guiding sloping plate 420, and a clamping component 440 is installed at the outer top end. A storage component 450 is installed on the outer side of the liquid guiding sloping plate 420. The storage component 450 stores multiple sets of separators 500 that mate with the clamping component 440. The separators 500 are used to divide the area above the liquid guiding sloping plate 420 into a specified number of coating areas and agitate the liquid in the coating areas. When the separators 500 are retracted into the storage component 450, the storage component 450 scrapes off the residual liquid on the side of the separators 500. A drainage gap is left between the storage component 450 and the liquid guiding sloping plate 420. Liquid receiving assembly 460 is installed inside the bottom of the coating protective cover 300 and is used to receive residual liquid scraped off; the liquid guiding slant plate 420, the storage component 450 and both ends of the liquid receiving assembly 460 are fixed inside the coating protective cover 300. Liquid guiding assembly 600 is installed inside the top of coating shield 300 and above the coating area. Liquid guiding assembly 600 is used to guide liquid into the coating area. The Joule heating assembly 800 is installed at the output end of the coating assembly 400; the Joule heating assembly 800 is used to rapidly heat the substrate to the specified experimental value using the Joule heating principle; The spraying assembly 700 is installed on top of the Joule heating assembly 800. When the spraying assembly 700 is working, the end of the liquid receiving assembly 460 blocks the coating area of ​​the liquid guiding inclined plate 420 to form a liquid collection pool, and the input end of the spraying assembly 700 is connected to the coating area above the liquid guiding inclined plate 420. The substrate winding assembly 900 is installed at the output end of the Joule heating assembly 800 and located at the other end inside the heating chamber 100.

[0022] In the above scheme: 1. The substrate release assembly 200, coating / spraying assembly 700, Joule heating assembly 800, and winding assembly are sequentially connected. The Joule heating assembly 800 utilizes Joule heat to rapidly dry the coating layer, achieving continuous operation of "substrate release - coating / spraying - heating and drying - winding," which greatly improves the efficiency of experiments or production. Furthermore, the equipment has automatic web guiding control, closed-loop tension control, closed-loop linear speed control, and a closed-loop temperature control system, ensuring stable and reliable continuous operation.

[0023] 2. The coating assembly 400 enables seamless switching between coating and spraying processes, adapting to diverse substrate processing needs: The coating protective cover 300 can slide laterally along the displacement guide rail 110 on the inner wall of the heating box 100. When processing substrates that need to be coated, such as conductive carbon cloth, the coating protective cover 300 slides onto the substrate path, and the liquid guiding inclined plate 420 connects with the coating gap of the coating guide roller group 410, and the slurry is coated onto the substrate surface through the coating area. When processing substrates such as nickel mesh that require spraying, the coating protective cover 300 slides outward to detach from the substrate path, avoiding interference between the liquid guiding plate 420 and the substrate, and driving the internal coating assembly 400 (liquid guiding plate 420, coating guide roller group 410, etc.) to adjust its overall position; the sealing plate 462 of the liquid receiving assembly 460 rotates upward and is embedded in the notch 512 of the separator 500 to block the outlet end of the coating area, so that the coating area is transformed into a closed liquid collection pool, providing a stable slurry storage space for the spraying assembly 700. Thus, the two coating methods share a single liquid filling and storage structure, eliminating the need for two separate liquid filling and storage structures, resulting in lower costs. Furthermore, the liquid guiding inclined plate 420 can be divided into sections by the separator 500, allowing for zoned operations during both coating and spraying processes. Additionally, the separator 500's ability to agitate the liquid ensures smoother slurry flow during both coating and spraying processes, reducing sedimentation and clogging. 3. The partitioned coating structure supports multiple control experiments, improving experimental efficiency and data reliability: The top of the liquid guiding inclined plate 420 is divided into coating areas by a combination of side partitions 520 and central partitions 510. Two sets of side partitions 520 can form one coating area (for a single type of slurry), adding one set of central partitions 510 can form two coating areas, and adding two sets of central partitions 510 can form three coating areas, adapting to the simultaneous processing needs of 1-3 different slurries. The multiple liquid supply mains 610 of the liquid guiding assembly 600 correspond to different coating areas, and can separately deliver slurries with different formulations, ensuring independent slurry supply to each area and preventing cross-contamination, providing a precise basis for variable control in control experiments.

[0024] A single batch of processing can complete the simultaneous coating and heating drying of multiple slurries, directly obtaining performance data (such as drying rate, adhesion strength, etc.) of different slurries under the same heating conditions, without the need for repeated experiments in batches; 4. The storage component 450 can store unused dividers 500, making it easy to access different types of dividers 500. When the dividers are stored, the storage component 450 can also clean the residual liquid on the sides of the dividers 500. 5. The liquid receiving component 460 collects residual waste liquid from each area, avoiding contamination from mixing different slurries, ensuring the accuracy and comparability of control data, and reducing raw material waste and experimental costs; the liquid receiving component 460 can also seal the end of the coating area. 6. Whether in the open coating area during application or the closed collection tank during spraying, the separator 500 continuously agitates the slurry. For slurries with high solids content or easy settling, the rotation of the agitator 532 can disrupt the particle settling tendency, keeping the slurry in a uniformly dispersed state and avoiding "local thick / thin slurry" during coating or "nozzle clogging / uneven atomization" during spraying. Furthermore, the agitation intensity can be adjusted by the moving frequency of the longitudinal toothed plate 433 to adapt to the agitation requirements of slurries with different viscosities, ensuring that the slurry thickness on the substrate surface is uniform and the composition is consistent after coating / spraying, providing a fundamental guarantee for the performance stability after subsequent Joule heating and drying.

[0025] In this embodiment, the substrate release assembly 200 includes an unwinding air shaft 210, an unwinding side plate 220, a linear guide rail 230, a correction actuator motor 250, and a magnetic powder brake 240. Both ends of the unwinding air shaft 210 are equipped with first safety clamps 211, which are placed on the unwinding side plate 220. A set of linear guide rails 230 is slidably installed at the bottom of each set of unwinding side plates 220. A magnetic powder brake 240 is installed at one end of the unwinding air shaft 210, and the correction actuator motor 250 is connected to the inner wall of the unwinding side plate 220 on one side. The substrate release assembly 200 also includes floating roller side plates 260. Two sets of floating roller side plates 260 are disposed at the output end of the unwinding side plate 220. An inclined floating groove 261 is opened inside the floating roller side plate 260. A slider 271 is installed inside the floating groove 261. A floating roller 270 is rotatably mounted between the two sets of sliders 271. A first guide roller 280 is installed above one side of the floating roller 270 and a second guide roller 290 is installed below the other side. The first guide roller 280 and the second guide roller 290 are rotatably mounted between the two sets of floating roller side plates 260. The slider 271 is connected to the floating roller side plate 260 by a tension spring 272.

[0026] In the above scheme: 1. The moving roller slides along the inclined floating groove 261, and the tension spring 272 absorbs tension fluctuations to avoid sudden increases in tension that could damage the substrate or sudden decreases in tension that could lead to poor contact; the magnetic powder brake 240 adjusts the unwinding speed to achieve tension balance with the winding assembly. 2. The correction actuator motor 250 drives the unwinding side plate 220 to slide along the linear guide rail 230, adjusting the position of the unwinding air shaft 210 to ensure that the substrate is accurately aligned with the subsequent coating and heating components, thereby improving coating uniformity and heating stability. 3. The first and second guide rollers guide the substrate path, and together with the floating roller 270, they achieve a smooth transition during the release process, reducing substrate wrinkles or stretching deformation.

[0027] In this embodiment, the coating guide roller assembly includes coating side plates, and a first coating roller 411 and a second coating roller 412 are installed above the two coating side plates, with a coating gap between the first coating roller 411 and the second coating roller 412; a third guide roller 413 is installed on one side of the bottom of the second coating roller 412, and a fourth guide roller 414 is installed below the third guide roller 413.

[0028] In the above scheme: the first and second coating rollers between the two sets of coating side plates form a fixed coating gap, providing stable pressure and thickness reference for slurry coating and avoiding uneven coating. The third and fourth guide rollers 414 are arranged sequentially along the substrate path to guide the coated substrate to smoothly transition to the Joule heating assembly 800, avoiding substrate displacement or wrinkles and ensuring close contact between the substrate and the electrode rollers during heating.

[0029] In this embodiment, the liquid guiding inclined plate 420 is provided with T-shaped fixed side frames 421 at both ends. The inner end of the fixed side frame 421 is provided with a swing driving component 430 and the outer end is provided with a clamping component 440. The swing driving component 430 includes a longitudinal toothed plate 433, a longitudinal guide rail 432, a first driving rod 435 and a longitudinal hanging plate 431. The two ends of the longitudinal hanging plate 431 are fixedly connected to the top inner end of the fixed side frame 421. The bottom end of the longitudinal hanging plate 431 is provided with a longitudinal guide rail 432. The longitudinal toothed plate 433 is slidably installed on the side of the longitudinal guide rail 432.

The base plate 441 and the longitudinal guide rail 432 are both arranged parallel above the liquid guiding inclined plate 420.

[0030] In the above scheme: The fixed side frame 421 fixes both ends of the liquid guiding inclined plate 420. The snap-fit ​​strip 442 of the snap-fit ​​component 440 has multiple sets of snap-fit ​​slots 443. The snap-fit ​​plate 514 of the separator 500 can be quickly inserted and positioned to avoid liquid cross-contamination.

The longitudinal toothed plate 433 of the swing drive component 430 reciprocates along the longitudinal guide rail 432, and can mesh with the driven gear 533 of the connecting separator 500 to provide power for the agitator 530; the contact bar 434 unlocks the elastic pawl 534, realizing the linkage control of drive and positioning, and simplifying operation.

[0031] Traditional multi-slurry control experiments require batch processing, which is inefficient; the slurry is prone to sedimentation in the coating area, leading to uneven coating. In this embodiment, the separator 500 includes a central partition 510 and a side partition 520. The structure of the central partition 510 is the same as that of the side partition 520. Two sets of agitating components 530 are symmetrically arranged at one end of the central partition 510, and a set of agitating components 530 is installed on the inner end of the side partition 520.

[0032] The partition plate 510 includes a main body 511. The inner end of the main body 511 is provided with a notch 512 for adapting to the second coating roller 412. The top of the outer end of the main body 511 is provided with a vertical box 513. A retaining plate 514 is slidably installed on the inner side of the vertical box 513.

The driven gear 533 is located on the top of the extension plate. The top of the extension plate is provided with an elastic claw 534. The elastic claw 534 cooperates to elastically engage the driven gear 533. The stirring plate 532 is used to stir the liquid inside the coating area. When the separator 500 is inserted into the top of the liquid guiding inclined plate 420, the main body 511 is inserted between the base plate 441 and the liquid guiding inclined plate 420, the clamping plate 514 is vertically inserted into the clamping slot 443, the vertical box body 513 stops on the outside of the clamping strip 442, the longitudinal toothed plate 433 meshes with the driven gear 533, and the abutting strip 434 abuts against the unlocking elastic pawl 534.

[0033] In the above scheme: The combination of the partition and the side partition 520 can divide the coating area into 1-3 zones, allowing for the processing of multiple types of slurry in a single operation without the need for batch operations, thus significantly improving the efficiency of control experiments. The stirring plate 532 of the stirring component 530 can rotate and stir the slurry to prevent sedimentation. The main body 511 is inserted between the liquid guiding inclined plate 420 and the bottom plate 441, and the retaining plate 514 is embedded in the retaining groove 443 for fixation. The longitudinal toothed plate 433 engages with the driven gear 533 to drive the stirring, ensuring that the separator 500 is firmly installed and the stirring is smooth.

[0034] In this embodiment, the liquid receiving component 460 includes a liquid receiving box 461. The front end of the liquid receiving box 461 is rotatably connected to a sealing plate 462, and a flipping motor 463 is installed at the rotatable connection. The liquid receiving box 461 is located at the bottom of the liquid guiding inclined plate 420, and the collecting end of the liquid receiving box 461 is placed at the bottom of the drain gap. When the spraying component 700 is working, the coating protective cover 300 drives the coating component 400 and the liquid receiving component 460 to move as a whole, so that the liquid guiding inclined plate 420 is disengaged from the second coating roller 412, and the sealing plate 462 rotates upward to seal the coating area.

[0035] In the above scheme: the coating protective cover 300 drives the entire component to move horizontally, causing the liquid guiding inclined plate 420 to detach from the substrate path and avoid interference; the sealing plate 462 rotates upward to seal the coating area, forming a closed liquid collection pool to meet the spraying requirements. The liquid receiving box 461 is located at the bottom of the drain gap and receives and stores the residual slurry from the storage component 450 and the liquid guiding inclined plate 420.

[0036] In this embodiment, the coating protective cover 300 includes two sets of movable side plates 320 and a cover 310. The inner wall of the heating box 100 is symmetrically provided with displacement guide rails 110. The outer wall of the movable side plate 320 is provided with a movable block 321. The movable block 321 is slidably embedded in the displacement guide rail 110. The two sets of movable side plates 320 are fitted with the cover 310 by screws. One side of the cover 310 is provided with a tube-penetrating notch 311.

[0037] In the above solution: the cover 310 protects the internal structure of the coating assembly 400 to prevent contamination; the moving block 321 slides along the displacement guide rail 110 of the heating box 100, realizing the overall translation of the coating protective cover 300, allowing mode switching without disassembly. The pipe penetration notch 311 of the cover 310 provides clearance for the liquid guiding and spraying pipelines, ensuring that the pipelines are not pulled when the coating protective cover 300 moves, thus improving the operational stability of the equipment.

[0038] In this embodiment, the storage component 450 includes a tray 451 with an L-shaped side cross-section. Multiple sets of positioning plates 452 are longitudinally spaced on the surface of the tray 451. A V-shaped groove 455 is opened at the inner end of the positioning plate 452, and a positioning slot 456 is formed between adjacent positioning plates 452. When the separator 500 is placed on the tray 451, the main body 511 and the stirring plate 532 are respectively placed into a set of positioning slots 456. The V-shaped groove 455 cleans the sides of the main body 511 and the stirring plate 532, and the extension plate 531 is placed above the positioning plate 452.

[0039] In the above scheme: when the separator 500 is inserted into the positioning slot 456, the V-shaped groove 455 of the positioning plate 452 scrapes off the residual slurry on the sides of the main body 511 and the stirring plate 532, eliminating the need for manual cleaning and improving efficiency. The positioning slot 456 stores the main body 511 and the stirring plate 532 separately to avoid confusion and damage; the scraped residue flows into the liquid receiving box 461 through the drainage gap, realizing centralized treatment of waste liquid.

[0040] In this embodiment, the liquid guiding assembly 600 includes three sets of liquid filling main pipes 610. The inner end of each set of liquid filling main pipes is connected to a set of liquid filling bellows 620, and the outer end is connected to a set of liquid filling pumps 640. The three sets of liquid filling pumps 640 are installed on the liquid storage tank 630. The spraying assembly 700 includes a spraying frame 750, which is positioned at the top between the heated side plates 810 and above the two sets of water-cooled electrode rollers 830. The spraying frame 750 has three spraying areas. The top of the spraying frame is connected to three sets of liquid spraying main pipes 730. The input end of each set of liquid spraying main pipes 730 is connected to a set of liquid pumps 740. The three sets of liquid pumps 740 are connected to three sets of liquid pumping main pipes 710. The inner end of each set of liquid pumping main pipes 710 is connected to a set of liquid pumping bellows 720. The three sets of liquid pumping main pipes 710 and the three sets of liquid supply main pipes all horizontally penetrate the pipe notch 311.

[0041] In the above solution: three sets of liquid supply main pipes 610 correspond to three coating areas, and three sets of liquid spraying main pipes 730 correspond to three spraying areas of the spraying frame 750, achieving precise supply of different slurries and avoiding confusion. Mobility and integration: the liquid supply / extraction corrugated pipe 720 is telescopic, adapting to the docking needs of different coating areas; the pipeline is centrally connected through the pipe notch 311, resulting in a compact structure and eliminating the need for multiple independent liquid supply devices.

[0042] In this embodiment, the Joule heating assembly 800 includes a heating side plate 810, and two sets of water-cooled guide rollers 820 and water-cooled electrode rollers 830 are symmetrically arranged between the two sets of heating side plates 810. The water-cooled electrode rollers 830 are located above the inner side of the water-cooled guide rollers 820, and the substrate passes horizontally through the top of the two sets of water-cooled electrode rollers 830. An infrared temperature probe is installed at the bottom between the two sets of water-cooled electrode rollers 830. The substrate winding assembly 900 includes a tension measuring roller 910 and a winding air shaft 940. Both ends of the tension measuring roller 910 are equipped with seated bearings 920, and a set of tension sensors 930 is installed at the bottom of each set of seated bearings 920. Both ends of the winding air shaft 940 are equipped with second safety clamps 950, and the bottom of the second safety clamps 950 is installed on the winding side plate 960. One end of the winding air shaft 940 is connected to a servo motor 980 through a synchronous belt 970.

[0043] In the above scheme: the water-cooled electrode roller 830 utilizes Joule heating to rapidly heat the substrate, and an infrared temperature probe provides real-time temperature feedback. A PID system is used to regulate the current and voltage, ensuring precise temperature control. The water-cooling structure prevents overheating and damage to the electrodes. The tension sensor 930 of the tension measuring roller 910 detects the tension and feeds it back to the magnetic powder brake 240 to adjust the unwinding speed. The winding air shaft 940 is driven by a servo motor 980, achieving stable tension throughout the "unwinding-heating-winding" process and ensuring winding quality and effective heating contact.

[0044] Working principle and usage process of this invention: S1, Substrate Release: The servo motor 980 drives the take-up air shaft 940 to rotate via the synchronous belt 970, which releases the substrate outside the unwind air shaft 210 and, after heat treatment, winds it onto the take-up air shaft 940. The unwinding air shaft 210 has a built-in correction mechanism, which consists of a linear guide rail 230 and a correction actuator motor 250 mounted on the base frame and connected to the unwinding side plate 220. It can control the position of the wound substrate, ensure the contact position between the substrate and the water-cooled electrode roller 830, and improve the winding quality. The substrate passes through the first guide roller 280, the floating roller 270 and the second guide roller 290 in sequence. During the conveying process, the slider 271 can move along the floating groove 261. The tension spring 272 drives the slider 271 to tend to return to its original position. It can absorb and release tension, play a protective role when the tension changes rapidly, and avoid damage to the substrate when the tension increases rapidly and poor contact between the substrate and the electrode roller when the tension decreases rapidly. S2. Select coating or spraying treatment according to the type of substrate; the substrate is a conductive material; for example, if the substrate is carbon cloth, coating can be used, proceed to S3; if the substrate is nickel mesh, spraying can be used, proceed to S4. S3. Substrate coating and drying process: Before coating, the worker can adjust the number of coating zones on the guide plate 420 according to the type of slurry to be studied in the experiment. If only one type of slurry needs to be studied, the worker needs to install two sets of side partitions 520, forming one coating zone between the two sets of side partitions 520. If two types of slurry need to be studied, the worker needs to install two sets of side partitions 520 and one set of middle partitions 510, forming two coating zones on both sides of the middle partition 510. Two types of slurry can then be coated on the substrate simultaneously for comparison experiments. If two types of slurry need to be studied, the worker needs to install two sets of side partitions 520 and two sets of middle partitions 510, forming three coating zones on both sides of the two sets of middle partitions 510. Three types of slurry can then be coated on the substrate simultaneously for comparison experiments. The installation process of the side partition 520 and the middle partition 510 is as follows: the main body 511 is placed between the base plate 441 and the liquid guiding inclined plate 420, the vertical box body 513 abuts against the back of the snap-fit ​​strip 442, the worker lifts the positioning plate 452, so that the positioning plate 452 moves upward along the vertical box body 513 and stretches the spring rod 515. When the positioning plate 452 is aligned with the slot 443 at the designated position, the positioning plate 452 is released, so that the positioning plate 452 is inserted into the slot 443 to achieve quick positioning; when the middle plate body is inserted, the abutment strip 434 will abut against the unlocking elastic claw 534 in the opposite direction, so that the driven gear 533 can freely mesh with the longitudinal tooth plate 433; the liquid storage tank 630 has three storage chambers, and slurry can be added to the storage chambers; After the coating areas are separated, the liquid filling bellows 620 is positioned above the corresponding coating area, and the corresponding number of liquid filling pumps 640 are activated. The liquid filling pumps 640 draw liquid from the corresponding storage tanks 630 and then fill the coating area through the liquid filling main pipe 610 and the liquid filling bellows 620. The first drive rod 435 drives the longitudinal toothed plate 433 to reciprocate, which in turn drives the stirring plate 532 to rotate. The stirring plate 532 can then stir the liquid in the coating area, increase its fluidity, and prevent sedimentation. The coating liquid is applied to the substrate in sections. After coating, the substrate passes through the first coating roller 411 and the second coating roller 412, and then passes through the water-cooled guide roller 820 and the water-cooled electrode roller 830 in sequence. The substrate passes over the two sets of water-cooled electrode rollers 830. The heating temperature is set and the heating is turned on. The power supply provides power to the water-cooled electrode rollers 830, so that the substrate between the two water-cooled electrode rollers 830 is energized. The substrate is heated rapidly using the principle of Joule heating, and the slurry on the substrate dries quickly. The temperature of the substrate is measured in real time by an infrared temperature probe and fed back to the PID control system. The PID adjusts the current and voltage of the power supply to achieve precise temperature control. S4. Substrate spraying and drying treatment: The top of the guide plate is divided into sections, and the coating area can be one, two or three. The displacement guide rail 110 drives the coating protective cover 300 to move, so that the tray 451, the liquid guide plate 420 and the liquid receiving box 461 move outward. The flipping motor 463 drives the sealing plate 462 to move upward, so that the sealing plate 462 is embedded in the notch 512 and blocks the outlet end of the coating area, so that each coating area becomes a liquid collection pool. After adjusting the discharge position of the liquid filling bellows 620, the corresponding number of liquid filling pumps 640 will draw out the corresponding liquid, and then discharge it to the corresponding coating area through the liquid filling main pipe 610 and the liquid filling bellows 620; then adjust the liquid extraction bellows 720 to be inserted into the coating area. The substrate passes sequentially through the water-cooled guide roller 820 and the water-cooled electrode roller 830, and passes over the two sets of water-cooled electrode rollers 830. Three sets of liquid pumps 740 operate, causing liquid to be sprayed out from the three sets of spray nozzles of the liquid pumping bellows 720, the liquid pumping main pipe 710, and the spraying frame 750. The sprayed liquid is rapidly heated and dried after contacting the substrate, achieving instantaneous heating of the sample and realizing continuous instantaneous heating. During the above spraying process, each set of stirring plates 532 stirs the liquid in the liquid collection tank, so that the slurry can also be stirred and output during the spraying process. S5. Substrate winding: After drying, the substrate passes through the tension measuring roller 910 and is wound onto the take-up air shaft 940. The tension sensor 930 on the tension measuring roller 910 detects the tension of the substrate in real time and feeds it back to the magnetic powder brake 240 on the unwinding air shaft 210 through the tension controller to achieve closed-loop tension control. Stable tension can ensure stable contact between the substrate and the water-cooled electrode roller 830 and ensure the quality of winding. S6, Separator 500 Recycling and Cleaning: Lifting the card plate 514 allows the separator 500 to be pulled out. Then, the separator 500 is inserted between the positioning plates 452. The main body 511 is inserted into one set of positioning slots 456, and the stirring plate 532 is inserted into another set of positioning slots 456. The V-shaped groove 455 at the end of the positioning plate 452 can clean the residual liquid on the outside of the main body 511 and the stirring plate 532. The residual liquid is discharged into the liquid receiving box 461 through the gap between the support plate 451 and the liquid guiding inclined plate 420. The coating protective cover 300 moves outward, the second drive rod 453 drives the scraper 454 to move outward, the scraper 454 scrapes off the residual liquid on the surface of the liquid guiding inclined plate 420, and the residual liquid is discharged into the liquid receiving box 461.
