Description

Technical Field

[0001] The present invention relates to the technical field of film casting equipment, in particular to a composite diaphragm film casting machine. Background Art

[0002] Composite membranes are insulating layers composed of thin films of varying layers and materials, used to isolate and protect against interactions between different environments or media. They offer high chemical stability, excellent mechanical properties, high-temperature resistance, corrosion resistance, and permeation resistance, making them widely used in a variety of applications. Composite membranes are typically constructed from two or more layers of materials, combined through lamination or co-extrusion. These materials, including polymers, metal foils, cellulose, polyester, polyimide, and polyurethane, are typically fused together at micron-level thicknesses through specialized production processes, creating a structure with composite properties.

[0003] Chinese patent CN202711528317.2 discloses a coating machine for the production of composite diaphragms for hydrogen production by alkaline water electrolysis, comprising a coaxially arranged unwinding roller, a winding roller, a spray pipe and several support rollers. The spray pipe is driven by a supergravity motor to rotate at high speed, driving the entire coating machine to create a supergravity environment. Under the action of supergravity, the paint is sprayed out through the spray pipe and evenly coated on the surface of the composite diaphragm to form a dense and uniform coating. The support roller supports the composite diaphragm to prevent it from deformation. The rotation of the unwinding roller and the winding roller is controlled by the winding motor to achieve continuous coating of the composite diaphragm. The excess paint generated during the coating process is collected and recycled through the reflux hole. The unwinding roller and the winding roller are provided with a hollow structure and an internal piston, which cooperate with the balance cylinder and the adjustment oil cylinder to achieve dynamic balance to ensure a smooth coating process. The supergravity motor is independently suspended for vibration reduction, and the outer box is closed, which is conducive to stable operation and clean production of the coating machine.

[0004] However, this technical solution has low single-sided coating efficiency and is difficult to achieve double-sided simultaneous coating. It cannot meet production needs and has poor applicability. Summary of the Invention

[0020] The beneficial effects of the present invention are:

[0021] (1) The present invention adopts dual-die synchronous coating technology, adopts symmetrically arranged slit extrusion coating dies on both sides, and realizes synchronous coating of slurry on both sides of the substrate through precision metering pumps and flow field control, avoiding the repeated action of winding and unwinding twice required for traditional single-sided coating, and realizes synchronous, efficient and simplified process of double-sided coating of the substrate, thereby significantly improving processing efficiency.

[0022] (2) The present invention drives multiple sets of groove pressing rollers to rotate through the movement of the cloth, and the chain belt a on the sprocket a causes the multiple sets of groove pressing rollers to rotate synchronously, thereby applying pressure to the front and back sides of the cloth through the multiple sets of pressing cones, so that the front and back sides of the cloth are evenly covered with grooves, and the driving gear is engaged with the multiple sets of pressing cones on the groove pressing rollers, so that the rotation of the groove pressing rollers can drive the connecting rod a to rotate, and the chain belt b on the sprocket b synchronously drives the cams on the two sets of connecting rods a to rotate continuously, and squeezes the push rod when the raised edge rotates to the bottom, so that the push rod overcomes the rebound force of the reset spring on the sleeve and drives the printing plate to move to squeeze the front and back sides of the cloth, and the rebound force of the reset spring is used on the cam 2452 When resetting, the printing plate is driven to reset to perform reciprocating imprinting on the moving cloth, and the adhesion effect of the rubber during coating is improved by the application of grooves and gravures, thereby further improving the coating effect; after coating is completed, the stepper motor is energized to drive the two sets of worms on the connecting rod b to rotate synchronously, and the two-way lead screw is driven to rotate through the engagement of the worm wheel and the worm, and the reverse threads at both ends of the two-way lead screw are threadedly connected with the lead screw nut to drive the rubber pressing plates on the two sets of connecting blocks to move toward each other, so as to adjust the contact tightness between the rubber pressing plates and the cloth, so that the rubber pressing plates will be pressed tightly on the coated cloth, so that the rubber can be pressurized to penetrate into the grooves, ensuring the coating effect while making the rubber adhere evenly.

[0023] (3) When the concave wheel deviates during the fabric coating process, the present invention drives the traction piston to move backward in the sealing cylinder through the traction rod, driving the input electrode column on the piston plate to overcome the reverse force of the air pressure in the sealing cylinder and the return spring, and contacting the output electrode column on the adjustment plate, so that the alarm device circuit is connected, thereby triggering the alarm device to promptly remind the material deviation situation; at the same time, the backward movement of the piston causes the overall space volume of the sealing cylinder and the pressure cylinder to decrease, and the air pressure to increase. The air pressure change signal value can be received by the air pressure sensor, and further remotely remind the staff. The double reminder method can promptly remind and respond.

[0024] (4) The present invention filters the water through the filter plate in the filter box and returns it to the water storage tank for recycling. The cylinder b drives the motor b and the gear column to slide on the guide rail seat, so that the gear column contacts and meshes with the gear b. The motor b drives the gear b to rotate, and the other set of gears b meshes with it, thereby driving the other set of gears b to rotate in the opposite direction. The two sets of gears b respectively drive the two sets of limiting blocks b to rotate in opposite directions through the belt b. The two sets of limiting blocks b drive the two sets of limiting blocks a to rotate in opposite directions through the cross belt group, so that the two sets of limiting blocks b and the two sets of limiting blocks a rotate synchronously into the filter box and no longer restrict the upper filter plate. The filter can be pulled back by the retraction force of the spring a. The plate is pulled to the drain plate, and the cone needle can squeeze out the impurities blocked in the filter holes of the filter plate; when the two sets of limit blocks a rotate, they will contact the blocking plate, and through their continuous rotation, they will push the blocking plate to overcome the elastic force of the spring b and retract into the sewage box, so that the sewage pipe and sewage trough are unblocked; start the cylinder b again to drive the tooth column to contact and engage with the gear a, and the driven rotation of the gear a and the transmission of the belt a drive the gear a on the two sets of rotating shafts to rotate synchronously, and the meshing of the tooth plate pushes the cleaning plate to move horizontally to push the impurities on the filter plate out of the sewage pipe for cleaning. The automated filtering and cleaning setting greatly improves the overall practicality of the device and effectively improves the processing efficiency.

[0025] (5) The present invention extends the flow of filtered clean water through the inclined surface of the cone plate, and the extended water resources will drip out from the multiple groups of drainage holes on the outer ring, which can increase the reflux time and the contact range with the air in the pipeline to improve the heat exchange and cooling effect. The motor C drives the screw to rotate, and the threaded connection between the nut on the cone plate and the screw drives the cone plate to rise and fall when the screw is reversed, further adjusting its flow resistance and heat exchange effect. The air fan is used to discharge the hot air in the drainage pipe, further improving the cooling effect, so that the water temperature in the cleaning tank box after reflux is always at a low state.

[0026] In summary, the present invention has the advantages of high efficiency and precision. BRIEF DESCRIPTION OF THE DRAWINGS

After discharge, the sewage is filtered by the filter plate 413 in the filter box 412 and then recycled; during the continuous filtration process, impurities will accumulate on the filter plate 413. At that time, the retraction force of the spring a416 can pull the filter plate 413 to the drain plate 414, and the cone needle 415 can squeeze out the impurities blocked in the filter holes of the filter plate 413, and the impurities can be discharged through the sewage box 417 and the sewage pipe 418.

[0081] When the filter box 412 is in the closed position, the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 413 is in the closed position, and the filter plate 3 slides down for cleaning; when the two sets of limit blocks a433 rotate, they will contact the blocking plate 431, and the guide wheel 434 can reduce the contact friction resistance. After continuous rotation, the blocking plate 431 can be pushed into the sewage box 417, so that the sewage pipe 418 and the sewage trough are unblocked and can be further cleaned in the next step; the guide rail seat 442 is set obliquely, and its angle is consistent with the angle of the connection line between a set of gears b437 and a set of rotating shafts 427. The cylinder b444 drives the motor b445 and the gear column 446 to slide on the guide rail seat 442, so that the gear column 446 can selectively contact and mesh with the gear b437 and the gear a428, and further drive the gear b437 and the gear a428 through the motor b445. The teeth of the gear column 446 are smaller than the teeth of the two sets of gears, and its oblique movement can drive the two sets of gears to deflect slightly by friction, further making the gear column 446 stably meshed with the two sets of gears to ensure the transmission effect.

[0082] The heat dissipation assembly 45 includes: a cone plate 451, which is movably connected to the drain pipe 411; an outer ring 452, which is located at the bottom of the cone plate 451; a drainage hole 453, which is opened on the outer ring 452; a motor c454, which is located at the bottom of the drain pipe 411; a driving screw 455, which is located on the output shaft of the motor c454; a coupling 456, which is used to connect the driving screw 455 and the motor c 454 output shaft; bearing plate 457, bearing plate 457 is arranged on the inner wall of drain pipe 411; drive nut 458, drive nut 458 is arranged on the tip of cone plate 451; ventilation component 46 includes: oblique wall groove 461, oblique wall groove 461 is opened on the outer wall of drain pipe 411; air duct 462, air duct 462 is arranged on one side of oblique wall groove 461; air fan 463, multiple sets of air fans 463 are arranged in air duct 462; filter screen 464, filter screen 464 is arranged on air duct 462.

[0083] In this embodiment, the water filtered in the filter box 412 will fall on the cone plate 451 and flow downward through its inclined surface. The flowing water will drip out from the multiple groups of drainage holes 453 on the outer ring 452, which can increase the reflux time and increase the contact range with the air in the pipeline to improve the heat exchange and cooling effect. The motor c454 drives the drive screw 455 to be selected, and the threaded connection between the drive nut 458 on the cone plate 451 and the drive screw 455 drives the cone plate 451 to rise and fall when the drive screw 455 rotates forward and reversely, further realizing the adjustment of its flow resistance and heat exchange effect; the setting of the oblique wall groove 461 can avoid water leakage, and discharge the hot air in the drain pipe 411 through the air fan 463, further improving the cooling effect, so that the water temperature in the cleaning tank box 401 after reflux is always at a low state to ensure the cooling effect after the previous drying step.

[0084] Working steps

[0085] Step 1, corona process: The fabric is tensioned and unwound by the unwinding device 11, and then gradually passes through each device and docks with the rewinding device 34. The fabric is pulled by the rewinding device to move. When the fabric passes through the corona machine 13, high-frequency and high-voltage corona discharge generates low-temperature plasma, and the active particles are used to oxidize and roughen the material surface, thereby improving its surface energy and adhesion.

[0086] Step 2: Grooving process: The three sets of groove pressing rollers 231 rotate due to the resistance of the moving cloth, and the chain belt a235 on the sprocket a234 drives the three sets of groove pressing rollers 231 to rotate synchronously, so that the front and back sides of the cloth are pressed by multiple sets of pressing cones 232, so that the front and back sides of the cloth are evenly covered with grooves. The grooves improve the adhesion of the rubber during coating, thereby improving the coating effect;

[0087] The driving gear 2451 is meshed with the multiple groups of pressing cones 232 on the groove pressing roller 231. The rotation of the groove pressing roller 231 drives the connecting rod a245 to rotate, and the chain belt b2454 on the sprocket b2453 synchronously drives the cam 2452 on the two groups of connecting rods a245 to rotate continuously. When the raised edge rotates to the bottom, it squeezes the push rod 244, so that the push rod 244 overcomes the rebound force of the return spring 2442 on the sleeve 2441 and drives the printing plate 243 to move and squeeze the front and back sides of the cloth. The rebound force of the return spring 2442 drives the printing plate 243 to reset when the cam 2452 resets, thereby realizing reciprocating imprinting on the moving cloth, further improving the adhesion effect of the rubber material during coating through gravure printing, and further improving the coating effect.

[0088] Step 3, coating process: the cylinder a214 drives the coating die base 211 to slide on the slide rail a213, and the gap between the two sets of coating die heads 215 is further adjusted. The two sets of coating die heads 215 extrude the coating through the slit;

[0089] Step 4: Glue pressing process: The stepper motor 252 is energized to drive the two sets of worms 2521 on the connecting rod b2522 to rotate synchronously, and the worm wheel 2525 is engaged with the worm 2521 to drive the bidirectional screw 2524 to rotate. The reverse threads at both ends of the bidirectional screw 2524 are threadedly connected with the screw nut 253 to drive the glue pressing plates 254 on the two sets of connecting blocks 2531 to move toward each other, so as to adjust the contact tightness between the glue pressing plates 254 and the fabric, so that the glue pressing plates 254 will be pressed tightly against the coated fabric, allowing the glue to penetrate into the groove under pressure, ensuring the coating effect and making the glue uniformly adhered;

[0090] Step 5, alarm process: During the embossing and coating process, when the tensioned fabric deviates, the concave wheel 261 drives the traction piston 266 to move backward in the sealing cylinder 271 via the traction rod 265, driving the input electrode column 277 on the piston plate 273 to overcome the reverse force of the air pressure in the sealing cylinder 271 and the telescopic spring 274, and contact the output electrode column 276 on the adjustment plate 275, so that the alarm device circuit is connected, thereby triggering the alarm device to promptly remind people of the material deviation; at the same time, the piston moves backward, causing the overall space volume of the sealing cylinder 271 and the pressure cylinder 281 to decrease, and the air pressure to increase. The air pressure change signal value can be received by the air pressure sensor 283, and further remotely remind the staff;

[0091] Step 6: Gel Drying: Double-sided oven 31 dries both sides of the fabric by blowing hot air; gel box 32 evenly coats the gel on the fabric, allowing the coated gel to evaporate water and solvent at a certain rate to form a dry film;

[0092] Step 7, cleaning process: The cloth is cleaned in multiple stages by water circulation and spraying structures in multiple cleaning tanks 401, and then reeled up by the reeling device 34 after cleaning.

[0093] Step 8: Filtration process: The water in the multiple cleaning tanks 401 is filtered through the drain pipe 411 and the filter plate 413 in the filter box 412 and then flows back to the water storage tank for recycling;

[0094] Step 9, cleaning process: When too much impurities accumulate on the filter plate 413, the cylinder b444 drives the motor b445 and the gear column 446 to slide on the guide rail seat 442, so that the gear column 446 contacts and meshes with the gear b437, and the motor b445 rotates the gear b437, and the other set of gears b437 meshes with it, thereby driving the other set of gears b437 to rotate in the opposite direction, and the two sets of gears b437 respectively drive the two sets of limiting blocks b435 to rotate in opposite directions via the belt b438, and the two sets of limiting blocks b435 drive the two sets of limiting blocks a433 to rotate in opposite directions via the cross belt group 436, so that the two sets of limiting blocks b435 and the two sets of limiting blocks a433 rotate back into the filter box 412, and no longer restrict the upper filter plate 413, and the retraction tension of the spring a416 can pull the filter plate 413 onto the drain plate 414, and the cone needle 415 can squeeze out the impurities blocked in the filter pores of the filter plate 413;

[0095] When the two sets of limiting blocks a433 rotate, they will contact the blocking plate 431. Through their continued rotation, the blocking plate 431 will overcome the elastic force of the spring b432 and retract into the sewage box 417, so that the sewage pipe 418 and the sewage trough are unobstructed.

[0096] The cylinder b444 is started again to drive the tooth column 446 to engage with the gear a428. The driven rotation of the gear a428 and the transmission of the belt a429 drive the gear a428 on the two sets of rotating shafts 427 to rotate synchronously. The meshing of the tooth plate 426 pushes the cleaning plate 421 to move horizontally, pushing the impurities on the filter plate 413 out of the sewage pipe 418 to achieve cleaning. After the cleaning is completed, the filter plate 413 is driven to reset by the cylinder (not marked in the text) at the bottom of the filter plate 413, and the two sets of limiting blocks b435 and the two sets of limiting blocks a433 are driven to reset again to support and block the filter plate 413.

[0097] Step 10, cooling process: The filtered clean water will fall on the cone plate 451 and flow downward through its inclined surface. The flowing water will drip out from the multiple drainage holes 453 on the outer ring 452, which can increase the reflux time and the contact range with the air in the pipeline to improve the heat exchange and cooling effect. The motor c454 drives the drive screw 455, and the threaded connection between the drive nut 458 on the cone plate 451 and the drive screw 455 drives the cone plate 451 to rise and fall when the drive screw 455 is reversed, further adjusting its flow resistance and heat exchange effect. The air fan 463 is used to discharge the hot air in the drain pipe 411, further improving the cooling effect, so that the water temperature in the cleaning tank box 401 is always at a low state after reflux.
