Description
Technical Field
[0001] The present invention relates to the technical field of polyphenylene sulfide production, and particularly to a high-temperature sintering and stretching integrated machine for PPS hydrogen energy diaphragms. Background Art
[0002] Polyphenylene sulfide is a polymer containing repeating structural units of p-phenylene sulfide in its molecules and is a new type of functional engineering plastic. It has wide applications in the fields of electronics, automobiles, machinery, and chemicals. Polyphenylene sulfide is fully called polyphenyl sulfide and is a thermoplastic resin with phenylthio groups in the main chain of its molecules. Polyphenylene sulfide is a crystalline polymer. The as-spun fiber has a large amorphous region, with a crystallinity of about 5%. It undergoes exothermic crystallization at 125 °C, has a glass transition temperature of 150 °C, and a melting point of 281 °C. The drawn fiber generates partial crystallization during the drawing process, increasing to 20%. If the drawn fiber is heat-treated at a temperature of 130 to 230 °C, the crystallinity can be increased to 60 to 80%.
[0003] As disclosed in the Chinese patent with the publication number CN220903941U, a polyphenylene sulfide extruder includes an extrusion mechanism for extruding molten polyphenylene sulfide, a die for receiving the polyphenylene sulfide extruded by the extrusion mechanism, and a vibration defoaming mechanism for generating vibrations to discharge the bubbles in the polyphenylene sulfide in the die; the die is provided with a cavity for accommodating molten polyphenylene sulfide, and the extrusion end of the extrusion mechanism extends into the die; the die is arranged on the vibration defoaming mechanism. The vibration defoaming mechanism generates vibrations, and the bubbles in the molten polyphenylene sulfide are discharged by vibration. In this way, the bubbles contained in the polyphenylene sulfide are reduced, and the quality of the product is improved.
[0004] However, in the above-mentioned polyphenylene sulfide extruder, during the extrusion process of polyphenylene sulfide, it is not possible to roll and stretch the extruded polyphenylene sulfide at the same time, which makes it difficult to precisely control the crystallinity, resulting in unstable product performance, large differences between batches, and the produced products are more likely to crack or break when subjected to impact or bending.

[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. Through the design of the tubular furnace, sintering and extrusion mechanism, roll forming mechanism and stretching mechanism, during use, PPS granular materials can be poured into the sintering and extrusion mechanism. Then, the sintering and extrusion mechanism can push the PPS granular materials into the heating tank of the tubular furnace to be sintered and melted at high temperature. With the continuous pushing of the sintering and extrusion mechanism, the melted PPS material can be extruded from it and bitten by the roll forming mechanism for rolling. The two roll forming mechanisms can make the bitten diaphragm be pulled into a W shape and transmitted between them. The plastic diaphragm formed by rolling can be wound around the outer surface of the winding column. The winding column can be sleeved on the outer surface of the roll forming mechanism through the transmission belt sleeved on the outer surface of the second transmission disc. Thus, when the roll forming mechanism rolls the extruded diaphragm, it can simultaneously drive the winding column to wind the diaphragm. While winding the diaphragm, the stretching mechanism can be started simultaneously to continuously support the lower surface of the diaphragm to stretch it. Then, the stretched diaphragm can be wound by the winding column. Appropriate rolling and stretching can promote the regular arrangement of polyphenylene sulfide molecular chains, increase the crystallinity, thereby improving the properties such as the rigidity, heat resistance and chemical resistance of the material. During the whole production process, from the conveying, sintering and extrusion, roll forming, winding to stretching of the granular materials, each link cooperates with each other and has a high degree of automation. It not only reduces the workload and error of manual operation, but also improves the production stability and the consistency of product quality, which is conducive to large-scale industrial production.
[0020] 2. Through the design of the furnace tube, spiral conveyor blade, first motor and extrusion nozzle, during use, PPS granular materials can be poured into the feeding hopper opened at the upper end of the outer surface of the furnace tube. Subsequently, the first motor can be started to drive the spiral conveyor blade to push the poured PPS granular materials into the heating tank of the tubular furnace to be sintered at high temperature. Then, the sintered material can be pushed into the extrusion nozzle by the spiral conveyor blade to form a diaphragm and be extruded from it. And through the uniform rotation of the spiral conveyor blade, the conveying amount and conveying speed of the material can be accurately controlled, ensuring the continuity and stability of the material supply, which is conducive to the stable progress of the subsequent sintering and extrusion processes. And this precise extrusion and forming process helps to improve the consistency and yield rate of the product.
[0021] 3. Through the design of the second motor, the roller column, the second transmission disc and the third gear, the plastic diaphragm extruded by the extrusion nozzle can fall between the two groups of roller columns by the natural falling force, and the second group of roller columns can be driven to rotate by the second motor, so that the rotating second group of roller columns can engage the third gear of the other two groups of roller columns through the third gear, so that the other two groups of roller columns rotate clockwise, so that the two groups of relatively rotating roller columns can bite the extruded plastic diaphragm into the roller, and then the staff can guide it into the space between the second and third groups of roller columns to be bitten and driven out, and then the staff can again introduce the plastic diaphragm into the three groups of roller columns on the other side, so that the diaphragm segments between the three groups of roller columns on both sides can be pulled into a horizontal shape, and the diaphragm rolled out from the other side can be pulled into a horizontal shape. The film can be rolled up on the outer surface of the winding column, and the winding column can be meshed with the second gear through the first gear at one end, and the second gear can be driven to rotate by the transmission belt through the first transmission plate, and the other end of the transmission belt is set on the outer surface of the second transmission plate fixedly installed at one end of one group of roller columns, so that the roller column can be driven to rotate and the second transmission plate can be driven by the transmission belt to drive the winding column to rotate in the two groups of U-shaped grooves to roll up the diaphragm together, thereby avoiding the diaphragm being too long and causing wrinkles on the surface of the diaphragm. Multiple groups of roller columns rotate relative to each other and roll the plastic diaphragm in turn, which can make the diaphragm evenly stressed, better control the thickness and density of the diaphragm, ensure consistent performance everywhere, avoid problems such as uneven thickness and local density differences, and improve the overall quality and stability of the product.
[0022] 4. Through the design of the third motor, the triangular plate, the guide groove, the guide block, the supporting wheel, the push-pull rod and the first electric push rod, the third motor can be started after the diaphragm between the three groups of roller columns on both sides is pulled into a horizontal state, and the third motor can drive the supporting wheel rotatably installed between the triangular plates to rotate, so that the triangular plate can drive the supporting wheel to support the lower surface of the horizontal diaphragm, so as to realize the operation of supporting and stretching the diaphragm. In the process of supporting and stretching the diaphragm, the first electric push rod can be started to push or pull the push disk rotatably installed on the outer surface of the piston rod, so that The push-pull rod installed on the outer surface of the push disk pushes or pulls the three groups of guide blocks to slide outward or inward in the guide groove of the triangle plate synchronously to reduce or increase the distance between them, and there are support wheels installed rotatably between each two groups of vertically opposite guide blocks, which can drive the guide blocks to drive the support wheels installed rotatably to adjust the distance between them, and can allow the staff to adjust the degree to which the diaphragm is supported and stretched, so that the staff can flexibly adjust the stretching degree of the diaphragm according to actual production needs to meet different product specifications and performance requirements, and also improve the production flexibility and versatility of the equipment.

[0034] Among them, the diaphragm pulled into a W shape will be supported and stretched by a stretching mechanism 4 during the transmission process, the stretching mechanism 4 is rotatably installed between two fastening plates 115 and rotates within the U-shaped frame 101, and the two fastening plates 115 are fixedly installed on the lower surface of the U-shaped frame 101.
[0035] At one end of the tubular furnace 102, a mounting plate 106 is fixedly installed, on the lower surface of the mounting plate 106, two U-shaped groove openings 107 are formed, and a winding column 108 is rotatably placed and supported in the two U-shaped groove openings 107, at one end of the winding column 108, a first gear 110 is fixedly installed, the first gear 110 meshes with a second gear 111, the second gear 111 is rotatably installed at one end of the U-shaped groove opening 107, at one end of the second gear 111, a first transmission disc 112 is fixedly installed, on the outer surface of the first transmission disc 112, a transmission belt 114 is sleeved, the other end of the transmission belt 114 is sleeved at one end of the roll-forming mechanism 3, so that while the roll-forming mechanism 3 rolls the extruded diaphragm, it can synchronously drive the winding column 108 to wind the diaphragm through the second gear 111.
[0036] Through the design of the tube furnace 102, the sintering and extrusion mechanism 2, the roll pressing mechanism 3 and the stretching mechanism 4, during use, the PPS granular material can be poured into the sintering and extrusion mechanism 2, and the sintering and extrusion mechanism 2 can push the PPS granular material into the heating tank of the tube furnace 102 to be sintered and melted at high temperature.

Both ends of the furnace tube 202 extend out of the heating tank of the tube furnace 102, and a feeding hopper 203 is connected and installed on the outer surface of the furnace tube 202 extending to the outer end of the furnace tube 202. And a nozzle 205 is connected and installed at the lower end of the outer surface of the other end of the furnace tube 202.
[0038] A spiral conveyor blade 204 is rotatably installed in the furnace tube 202. One end of the spiral conveyor blade 204 is fixedly connected to the output shaft of the first motor 201.

[0062] a) A distributed temperature sensor array embedded in the inner wall of the tube furnace 102 at a spacing of 5 mm;
[0063] b) A high-precision encoder for real-time monitoring of the displacement of the top support wheel 405 (accuracy ±0.01 mm);
[0064] c) An industrial PC for solving the crystallinity equation at a cycle of 1 ms;
[0065] d) A servo driver for converting the X(t) deviation value into a PID control signal for the first electric push rod 408.
[0066] For example, when the top support wheel moves in a sine wave mode (amplitude h = 50 mm, frequency f = 0.5 Hz), the strain rate is calculated by real-time acquisition of displacement data through the encoder:

[0071] This equation has been verified in real time through online Raman spectroscopy. Under the optimized parameters of f = 0.8 Hz and h = 45 mm, the crystallinity of the PPS separator was successfully stabilized at 72 ± 1.5%, a 19.3% improvement over conventional processes. The digital twin system established with this model enables the prediction of separator microstructural evolution without downtime, providing theoretical support for the reliability of hydrogen separators.
[0072] Summarize and sort out the working steps of this solution according to the above technical solution: When in use, the PPS granular material can be poured into the feeding hopper 203 opened at the upper end of the outer surface of the furnace tube 202. Subsequently, the first motor 201 can be started to drive the spiral conveying blade 204 to push the poured PPS granular material into the heating tank of the tubular furnace 102 to be sintered at high temperature. Furthermore, the sintered material can be pushed into the extrusion nozzle 205 by the spiral conveying blade 204 to form a diaphragm and be extruded therefrom. The plastic diaphragm extruded by the extrusion nozzle 205 can fall between two sets of roller columns 302 by the force of natural dropping. The second set of roller columns 302 can be driven to rotate by the second motor 301. Furthermore, the rotating second set of roller columns 302 can drive the third gears 304 of the other two sets of roller columns 302 through the third gear 304 to mesh and drive, so that the other two sets of roller columns 302 rotate clockwise. Furthermore, the two sets of relatively rotating roller columns 302 can bite and roll the extruded plastic diaphragm. Subsequently, the staff can guide it between the second and third sets of roller columns 302 to be bitten and driven out. Subsequently, the staff can introduce the plastic diaphragm into the three sets of roller columns 302 on the other side again. Furthermore, the diaphragm in the section between the three sets of roller columns 302 on both sides can be pulled into a horizontal shape. The diaphragm rolled out from the other side can be wound on the outer surface of the winding column 108. The horizontally pulled diaphragm can start the third motor 401, and the third motor 401 can drive the top support wheel 405 rotatably installed between the triangular plates 402 to rotate. Furthermore, the triangular plate 402 can drive the top support wheel 405 to support the lower surface of the horizontally shaped diaphragm, so as to realize the operation of supporting and stretching the diaphragm. During the process of supporting and stretching the diaphragm, the first electric push rod 408 can be started to push or pull the pushing disk 407 rotatably installed on the outer surface of the piston rod. Furthermore, the pushing disk 407 can pull the push rod 406 rotatably installed on the outer surface to push or pull the three guide rail blocks 404 to slide outward or inward synchronously in the guide rail groove 403 of the triangular plate 402 to reduce or increase the distance therebetween. A top support wheel 405 is rotatably installed between every two vertically opposite guide rail blocks 404. Furthermore, the guide rail blocks 404 can drive the top support wheel 405 rotatably installed therebetween to adjust the distance therebetween, so that the staff can adjust the degree of the diaphragm being supported and stretched. Furthermore, the diaphragm after being rolled and stretched can be wound on the outer surface of the winding column 108. One end of the winding column 108 can be meshed with the second gear 111 through the first gear 110. The second gear 111 can be driven to rotate by the transmission belt 114 through the first transmission disk 112. The other end of the transmission belt 114 is sleeved on the outer surface of the second transmission disk 303 fixedly installed at one end of one of the roller columns 302. Furthermore, when the roller column 302 is driven to rotate, it will drive the second transmission disk 303 through the transmission belt 114 to drive the winding column 108 to rotate in the two U-shaped grooves 107 to wind the diaphragm together.
[0073] In summary, the PPS hydrogen energy diaphragm high-temperature sintering and stretching integrated machine can perform operations of rolling and stretching on the extruded diaphragm at the same time. Appropriate rolling and stretching can prompt the molecular chains of polyphenylene sulfide to be regularly arranged, increase the crystallinity, thereby improving the properties such as the rigidity, heat resistance and chemical resistance of the material. Moreover, in the whole production process, from the conveying of granular materials, sintering and extrusion, rolling forming, winding to stretching, each link cooperates with each other, and the degree of automation is relatively high. It not only reduces the workload and error of manual operation, but also improves the production stability and the consistency of product quality, which is conducive to large-scale industrial production.
