Laminated microporous membrane manufacturing apparatus

Abstract

This invention belongs to the field of microporous membrane manufacturing technology, specifically a laminated microporous membrane manufacturing device. It addresses the issue that during the stretching of microporous membranes, the stress attenuation and hysteresis effects occur as stress gradually propagates from the edges to the center, resulting in a thicker central region than the outer regions. This leads to smaller pore sizes in the central region and larger pore sizes on the outer regions, with uneven distribution of large pores, resulting in a decreased retention rate and reduced performance of the formed microporous membrane. The proposed solution includes a manufacturing platform with a dust cover bolted to one side. This laminated microporous membrane manufacturing device avoids the attenuation and hysteresis effects during the gradual stress transmission from the edges to the center during microporous membrane stretching, ensuring consistent thickness in both the central and outer regions. This results in a uniform overall pore size distribution of the microporous membrane, thereby improving the retention rate and enhancing its performance.

Description

Technical Field

[0001] This invention relates to the field of microporous membrane manufacturing technology, and in particular to a laminated microporous membrane manufacturing device. Background Technology

[0002] Polytetrafluoroethylene (PTFE) possesses excellent temperature resistance, acid and alkali resistance, and resistance to corrosion from various chemicals. It exhibits extremely good chemical stability, with a surface tension of (22-33) × 10⁻³ N / m. Its excellent hydrophobicity makes it a top choice for membrane distillation and waterproof / breathable materials. The manufacturing process of single-layer PTFE microporous membranes mainly includes mixing, preform preparation, extrusion, calendering, longitudinal and transverse stretching, and curing. Stretching forms a microporous membrane with a slit-pore structure. This membrane is then laminated onto various fabrics and substrates using a special process to create a new type of filter material. This membrane has small, uniformly distributed pores and high porosity, allowing it to filter all dust particles, including bacteria, while maintaining airflow, achieving the purpose of purification and ventilation. It is widely used in pharmaceuticals, biochemistry, microelectronics, and laboratory consumables.

[0003] During the stretching of microporous membranes, the stress gradually transfers from the edges to the center, resulting in attenuation and hysteresis effects. This causes the thickness of the middle region of the membrane to be greater than that of the two outer regions, leading to smaller pore sizes in the middle region and larger pore sizes in the outer regions. The uneven distribution of large pore sizes results in a decrease in the retention rate of the formed microporous membrane and a weakening of its performance. Summary of the Invention

[0004] This invention discloses a laminated microporous membrane manufacturing equipment, which aims to solve the technical problem in the prior art where, during the stretching of microporous membranes, the stress gradually transfers from the edge to the center, resulting in attenuation and hysteresis effects. This causes the thickness of the middle region of the membrane to be greater than that of the two side regions, resulting in smaller pore sizes in the middle region and larger pore sizes in the two side regions. The uneven distribution of large pore sizes leads to a decrease in the retention rate of the formed microporous membrane and a weakening of its performance.

[0005] The present invention proposes a laminated microporous membrane manufacturing equipment, including a manufacturing platform. A dust cover is fixedly connected to one side of the manufacturing platform by bolts. A stress component is arranged inside the dust cover. The stress component includes a fixed mounting plate and a mounting base. Two limiting cylinders are fixedly connected to one side of the fixed mounting plate. The same tension frame is slidably connected to the outside of the two limiting cylinders. Sliding openings are opened at equal intervals on both sides of the tension frame. Sliding frames are slidably connected at equal intervals inside the multiple sliding openings.

[0006] In a preferred embodiment, a return spring is fixedly connected to one side of each of the two adjacent sliding frames, one side of which is connected to one side of the slide opening. A circular hole is provided on one side of each sliding frame, and stress rollers are connected to the interior of two opposite circular holes through bearings. The same linkage support rod is fixedly connected to one side of multiple sliding frames.

[0007] In a preferred embodiment, a sliding hole is provided on one side of the fixed mounting plate, and a lifting cylinder is slidably connected inside the sliding hole. A second circular hole is provided on one side of the lifting cylinder, and a fixed cylinder is fixedly connected inside the second circular hole. Two reciprocating push-pull rods are fixedly connected to the outside of the fixed cylinder. A third circular hole is provided on one side of both the reciprocating push-pull rods and the linkage support rod. A rotating shaft is connected inside both third circular holes through bearings, and a connecting rod is movably connected to the outside of the two rotating shafts.

[0008] In a preferred embodiment, two fixing rods are fixedly connected to one side of the fixed mounting plate, and each fixing rod has a circular hole four on one side. A rotating cylinder is connected to the inside of the two circular holes four through a bearing. A semi-circular gear is fixedly connected to the outside of the rotating cylinder. A drive motor is fixedly connected to one side of the mounting base, and the drive end of the drive motor is connected to one side of the rotating cylinder through a coupling. A gear is fixedly connected to one side of the lifting cylinder, and the toothed end of the gear meshes with the semi-circular gear. Limit rollers are fixedly connected to both sides of the tension frame. The same heating panel is fixedly connected to the opposite sides of the dust cover, and a control box is fixedly connected to one side of the dust cover.

[0009] By incorporating stress components, during the stretching of the microporous membrane, the drive motor is activated, which in turn rotates a semi-circular gear. When the semi-circular gear meshes with the rack, the rack drives the lifting cylinder upwards. During this upward movement, the reciprocating push-pull rod on the lifting cylinder drives the connecting rod, causing the linkage support rod to move the sliding frame within the groove of the tension frame. At this point, the return spring is compressed. When the semi-circular gear disengages from the rack, the lifting cylinder descends due to gravity. Simultaneously, the rebound force of the return spring causes the stress rollers on the tension frame to compress and stretch the microporous membrane. Stress rollers are evenly spaced at the bottom of the tension frame. This prevents stress attenuation and hysteresis during the stretching of the microporous membrane, ensuring that the thickness of the middle region of the film is consistent with the thickness of the outer regions. This results in a uniform pore size distribution of the microporous membrane, thereby improving the retention rate of the formed microporous membrane and enhancing its performance.

[0010] In a preferred embodiment, an adsorption component is provided on one side of the dust cover. The adsorption component includes a mounting base three. A mounting circular hole is opened on one side of the dust cover. A rotating circular rod is connected to the inside of the mounting circular hole through a bearing. An installation long rod is fixedly connected to the outside of the rotating circular rod. A sliding groove is opened on the installation long rod. A hollow sliding frame is slidably connected to the inside of the sliding groove. An adsorption frame is fixedly connected to one side of the hollow sliding frame. The discharge end of the hollow sliding frame is connected to the inside of the rotating circular rod through a metal telescopic tube.

[0011] In a preferred embodiment, the mounting rod has a circular hole five, and a rotating shaft one is connected inside the circular hole five via a bearing. A linkage gear is fixedly connected to the outside of the rotating shaft one. The same circular toothed frame is fixedly connected to the opposite side of the dust cover. A rotating circular plate is fixedly connected to one side of the rotating shaft one. A circular hole six is ​​opened on one side of both the rotating circular plate and the hollow sliding frame. A rotating shaft two is connected inside the circular hole six via a bearing. The same push rod is movably connected to the outside of the two rotating shaft two.

[0012] In a preferred embodiment, a second mounting base is fixedly connected to the outside of the rotating rod, a pump body is fixedly connected to one side of the second mounting base, a filter plate is fixedly connected to the discharge end of the pump body, and a power motor is fixedly connected to one side of the third mounting base. The drive end of the power motor is connected to one side of the rotating rod via a coupling.

[0013] By incorporating an adsorption component, during the fabrication of the microporous membrane, the pump is activated, and the adsorption frame on the hollow sliding frame draws dust from the air inside the dust cover. The dust is then filtered and discharged through a filter plate. Simultaneously, the power motor is activated, driving the mounting rod on the rotating rod to rotate. This causes the adsorption frame to move circumferentially within the dust cover. During the rotation of the mounting rod, the linkage gear at one end of the mounting rod is limited by the toothed frame, causing the rotating plate to rotate. This rotating plate then drives the push rod, causing the hollow sliding frame to slide back and forth inside the mounting rod, increasing its adsorption area.

[0014] In a preferred embodiment, a disassembly and assembly assembly is provided on one side of the manufacturing platform. The disassembly and assembly assembly includes tooling brackets. Slide grooves are provided on both sides of the two tooling brackets. Mounting blocks are slidably connected inside the two slide grooves on the same side at equal distances. An insertion port is provided on one side of each mounting block. A socket is movably connected inside the multiple insertion ports. A telescopic spring II is fixedly connected to one side of each of the multiple sockets. Feed rollers are fixedly connected to the outside of two opposing telescopic spring IIs.

[0015] In a preferred embodiment, each of the plurality of mounting blocks has two sliding holes on one side, and a guide cylinder is slidably connected inside the plurality of sliding holes on one side. A telescopic spring is fixedly connected to one side of two adjacent mounting blocks.

[0016] By incorporating a disassembly and assembly component, the feed roller can be quickly replaced by inserting its socket end into one end of the mounting block on the tooling bracket when disassembling or assembling it, thereby improving manufacturing efficiency.

[0017] In a preferred embodiment, an observation port is provided on one side of the dust cover, and a transparent observation window is fixedly connected inside the observation port. A winding frame is fixedly connected to one side of the dust cover, and a winding motor is fixedly connected to one side of the winding frame. Two fixed mounting plates are fixedly connected to opposite sides of the dust cover. Two telescopic cylinders are fixedly connected to one side of each of the two fixed mounting plates. Tension adjusting roller one and tension adjusting roller two are fixedly connected to the output ends of the two telescopic cylinders located on the same side, respectively.

[0018] As can be seen from the above, the laminated microporous membrane manufacturing equipment provided by the present invention has the beneficial effect of avoiding attenuation and hysteresis effect in the process of stress gradually being transmitted from the edge to the middle when stretching the microporous membrane, so that the thickness of the middle region of the film is consistent with the thickness of the two side regions, thereby making the overall pore size distribution of the microporous membrane uniform, thereby improving the retention rate of the microporous membrane after molding and enhancing its use effect.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] The laminated microporous membrane manufacturing equipment disclosed in this invention is mainly used in scenarios where, during the stretching of microporous membranes, the stress gradually transfers from the edge to the center, resulting in attenuation and hysteresis effects. This causes the thickness of the middle region of the membrane to be greater than that of the two side regions, leading to smaller pore sizes in the middle region and larger pore sizes in the two side regions. The uneven distribution of large pore sizes results in a decrease in the retention rate of the formed microporous membrane and a weakening of its performance.

[0030] Reference Figures 1-5 A laminated microporous membrane manufacturing device includes a manufacturing platform 1. A dust cover 2 is fixedly connected to one side of the manufacturing platform 1 by bolts. A stress component 6 is provided inside the dust cover 2. The stress component 6 includes a fixed mounting plate 601 and a mounting base 619. Two limiting cylinders 605 are fixedly connected to one side of the fixed mounting plate 601. The same tension frame 606 is slidably connected to the outside of the two limiting cylinders 605. Sliding openings are opened at equal intervals on both sides of the tension frame 606. Sliding frames 607 are slidably connected at equal intervals inside the multiple sliding openings.

[0031] Reference Figures 1-5 Each of the two adjacent sliding frames 607 has a return spring 608 fixedly connected to one side. One side of the return spring 608 is connected to one side of the sliding opening. Each sliding frame 607 has a circular hole on one side. The interior of the two opposite circular holes is connected to a stress roller 621 through a bearing. The same linkage rod 609 is fixedly connected to one side of multiple sliding frames 607.

[0032] Reference Figures 1-5 A sliding hole is provided on one side of the fixed mounting plate 601. A lifting cylinder 613 is slidably connected inside the sliding hole. A second round hole is provided on one side of the lifting cylinder 613. A fixed cylinder 614 is fixedly connected inside the second round hole. Two reciprocating push-pull rods 612 are fixedly connected to the outside of the fixed cylinder 614. A third round hole is provided on one side of both the reciprocating push-pull rods 612 and the linkage support rod 609. A rotating shaft 610 is connected inside the two third round holes through bearings. A connecting rod 611 is movably connected to the outside of the two rotating shafts 610.

[0033] Reference Figures 1-5 Two fixing rods 615 are fixedly connected to one side of the fixed mounting plate 601. Each fixing rod 615 has a circular hole 4 on one side. A rotating cylinder 616 is connected to the inside of the two circular holes 4 through a bearing. A semi-circular gear 617 is fixedly connected to the outside of the rotating cylinder 616. A drive motor 620 is fixedly connected to one side of the mounting base 619. The drive end of the drive motor 620 is connected to one side of the rotating cylinder 616 through a coupling. A rack 618 is fixedly connected to one side of the lifting cylinder 613. The tooth block end of the rack 618 meshes with the semi-circular gear 617. Limit rollers 602 are fixedly connected to both sides of the tension frame 606. The same heating panel 603 is fixedly connected to the opposite sides of the dust cover 2. A control box 604 is fixedly connected to one side of the dust cover 2.

[0034] In specific application scenarios, when the microporous membrane is stretched, the drive motor 620 is activated, which drives the semi-circular gear 617 to rotate. When the semi-circular gear 617 meshes with the rack 618, the rack 618 drives the lifting cylinder 613 to rise. During the rise of the lifting cylinder 613, the reciprocating push-pull rod 612 on the lifting cylinder 613 drives the connecting rod 611, causing the linkage support rod 609 to drive the sliding frame 607 to move within the groove opened in the tension frame 606. At this time, the return spring 608 is compressed. When the semi-circular gear 617 meshes with the rack 618, the return spring 607 moves within the groove opened in the tension frame 606. When phase 18 separates, the lifting cylinder 613 should descend due to gravity. At the same time, the rebound force of the return spring 608 causes the stress roller 621 on the tension frame 606 to squeeze and stretch the microporous membrane. The stress rollers 621 are evenly spaced at the bottom of the tension frame 606. This avoids the attenuation and hysteresis effect in the process of stress gradually being transmitted from the edge to the middle when stretching the microporous membrane. This makes the thickness of the middle area of ​​the film consistent with the thickness of the two side areas, so that the overall pore size distribution of the microporous membrane is uniform. This improves the retention rate of the microporous membrane after molding and enhances its performance.

[0035] Reference Figure 1 , Figure 6 and Figure 7 An adsorption component 9 is provided on one side of the dust cover 2. The adsorption component 9 includes a mounting base 916. A mounting hole is provided on one side of the dust cover 2. A rotating rod 902 is connected to the inside of the mounting hole through a bearing. A mounting long rod 903 is fixedly connected to the outside of the rotating rod 902. A sliding groove is provided on the mounting long rod 903. A hollow sliding frame 904 is slidably connected inside the sliding groove. An adsorption frame 905 is fixedly connected to one side of the hollow sliding frame 904.

[0036] Reference Figure 1 , Figure 6 and Figure 7 The mounting rod 903 has a circular hole five. Inside the circular hole five, a rotating shaft 906 is connected via a bearing. A linkage gear 907 is fixedly connected to the outside of the rotating shaft 906. The same circular toothed frame 901 is fixedly connected to the opposite side of the dust cover 2. A rotating circular plate 908 is fixedly connected to one side of the rotating shaft 906. A circular hole six is ​​opened on one side of both the rotating circular plate 908 and the hollow sliding frame 904. Inside the circular hole six, a rotating shaft 914 is connected via a bearing. The same push rod 913 is movably connected to the outside of the two rotating shafts 914.

[0037] Reference Figure 1 , Figure 6 and Figure 7The rotating rod 902 is externally fixedly connected to a mounting base 909. A pump body 910 is fixedly connected to one side of the mounting base 909. A filter plate 911 is fixedly connected to the discharge end of the pump body 910. A power motor 915 is fixedly connected to one side of the mounting base 916. The drive end of the power motor 915 is connected to one side of the rotating rod 902 via a coupling.

[0038] In a specific application scenario, when manufacturing a microporous membrane, the pump body 910 is activated, and the adsorption frame 905 on the hollow sliding frame 904 sucks up dust from the air inside the dust cover 2. The dust is then filtered and discharged through the filter plate 911. At the same time, the power motor 915 is activated, which drives the mounting rod 903 on the rotating rod 902 to rotate, causing the adsorption frame 905 to move circumferentially inside the dust cover 2. During the rotation of the mounting rod 903, the linkage gear 907 at one end of the mounting rod 903 is limited by the toothed frame 901, causing the rotating plate 908 to rotate. This causes the rotating plate 908 to drive the push rod 913, which in turn drives the hollow sliding frame 904 to slide back and forth inside the mounting rod 903, increasing its adsorption area.

[0039] Reference Figure 1 and Figure 8 A disassembly assembly 10 is provided on one side of the manufacturing platform 1. The disassembly assembly 10 includes a tooling bracket 1001. Slide grooves are provided on both sides of the two tooling brackets 1001. Mounting blocks 1004 are slidably connected inside the two slide grooves on the same side. An insertion port is provided on one side of each mounting block 1004. A socket 1005 is movably connected inside the multiple insertion ports. A telescopic spring 1006 is fixedly connected to one side of each of the multiple sockets 1005. Feed rollers 1007 are fixedly connected to the outside of the two opposing telescopic springs 1006.

A telescopic spring 1003 is fixedly connected to one side of two adjacent mounting blocks 1004.

[0041] In specific application scenarios, when disassembling and assembling the feed roller 1007, the socket 1005 end of the feed roller 1007 is inserted into one end of the mounting block 1004 on the tooling bracket 1001, thereby quickly replacing the feed roller 1007 and improving its manufacturing efficiency.

[0042] Reference Figure 1 and Figure 2An observation port is provided on one side of the dust cover 2, and a transparent observation window 3 is fixedly connected inside the observation port. A winding frame 4 is fixedly connected to one side of the dust cover 2, and a winding motor 5 is fixedly connected to one side of the winding frame 4. Two fixed mounting plates 7 are fixedly connected to opposite sides of the dust cover 2. Two telescopic cylinders 8 are fixedly connected to one side of each of the two fixed mounting plates 7. Tension adjusting roller 11 and tension adjusting roller 2 12 are fixedly connected to the output ends of the two telescopic cylinders 8 located on the same side, respectively.

[0043] Working principle: When the microporous membrane is stretched, the drive motor 620 is activated, which drives the semi-circular gear 617 to rotate. When the semi-circular gear 617 meshes with the rack 618, the rack 618 drives the lifting cylinder 613 to rise. During the rise of the lifting cylinder 613, the reciprocating push-pull rod 612 on the lifting cylinder 613 drives the connecting rod 611, which causes the linkage support rod 609 to move the sliding frame 607 within the groove opened in the tension frame 606. At this time, the return spring 608 is compressed. When the semi-circular gear 617 disengages from the rack 618, the lifting cylinder 613 falls due to gravity. At the same time, the rebound force of the return spring 608 causes the stress rollers 621 on the tension frame 606 to compress and stretch the microporous membrane. The stress rollers 621 are evenly spaced at the bottom of the tension frame 606. When manufacturing the microporous membrane, the pump body 910 is activated, and the hollow sliding frame... The adsorption frame 905 on 904 absorbs dust from the air inside the dust cover 2, and then filters and discharges it through the filter plate 911. At the same time, the power motor 915 is started, which drives the mounting rod 903 on the rotating rod 902 to rotate, so that the adsorption frame 905 moves circumferentially inside the dust cover 2. During the rotation of the mounting rod 903, the linkage gear 907 at one end of the mounting rod 903 is limited by the toothed frame 901, which causes the rotating plate 908 to rotate. This causes the rotating plate 908 to drive the push rod 913 to drive the hollow sliding frame 904 to slide back and forth inside the mounting rod 903, increasing its adsorption area. When disassembling and assembling the feed roller 1007, the socket 1005 end of the feed roller 1007 is inserted into one end of the mounting block 1004 on the tooling bracket 1001, so as to quickly replace the feed roller 1007 and improve its manufacturing efficiency.
