[0014] A double-sided hydrophilic film coating method comprises the following steps: S1. Coating process: fix one end of the telescopic tube to the air guide tube located above, and fix one end of the existing coating material delivery tube to one end of the injection tube. According to the actual width of the substrate to be coated, increase or decrease the number of extension shafts, adjustment tubes and sleeves, so that the spliced ​​winding shaft and extension shaft can carry the sleeves after the number is adjusted, and then the spliced ​​splint can fully support the support tube and the adjustment tube. Wrap the substrate to be coated around the outer surface of the support tube and the adjustment tube on one side, so that the equipment can carry substrates of different sizes. Then, wrap one end of the substrate to be coated around the outer surface of the support tube and the adjustment tube on the other side, and then when the control starts the linkage When the motor is turned on, the linkage motor cooperates with the linkage shaft to drive the two linkage worms to rotate, and then the rotating linkage worms cooperate with the linkage worm gears to synchronously drive the winding shafts on both sides to rotate synchronously, and then the substrate to be coated on the side with more winding can be transported and wound to the side with less winding. In this process, the control motor located at the top is controlled to start, so that the control motor can drive the corresponding control rod to rotate, and the rotating control rod can adjust the bottom of the material storage frame located at the top to gradually fit the top of the substrate to be coated, and then the coating material can be continuously injected into the material storage frame through the existing coating material conveying pipe, and under the action of the first adjusting gear, the second adjusting gear and the two adjusting bevel gears The rotating linkage shaft can synchronously drive the reciprocating screw rod to rotate, and the rotating reciprocating screw rod can drive the diaphragm to move back and forth between the two first one-way valves. When the diaphragm moves from the upper first one-way valve to the lower first one-way valve, the space above the sealing frame gradually increases, and at the same time, the space below the sealing frame gradually decreases. In the process of gradually increasing the space above the sealing frame, the upper first one-way valve draws outside air into the space above the sealing frame, and at the same time, the upper second one-way valve can prevent the air inside the extension tube from being injected into the sealing frame. In the process of gradually decreasing the space below the sealing frame, the lower first one-way valve can prevent the air inside the sealing frame from being discharged. The second one-way valve located at the bottom can gradually transport the air below the sealing frame to the inside of the extension tube, and then during the reciprocating movement of the diaphragm, the air in the internal space of the sealing frame can be continuously injected into the inside of the extension tube, and then the injected flowing air can be injected into the inside of the air guide tube located at the top through the telescopic tube, and then the flowing air can transport the synchronously injected coating material to the inside of the material storage frame, and the coating material injected into the material storage frame gradually fills the space inside the material storage frame and below the sealing plate, and then the coating material can be discharged through the discharge hole and transported to the top of the substrate to be coated, and at the same time, under the extrusion of the bottom of the sealing frame, the coating material can be evenly coated on the top of the substrate to be coated; S2, shaping treatment: by controlling and starting the moving motor, the moving motor can drive the first moving rod to rotate, and the rotating first moving rod can move and adjust the use position of the moving frame, so that the moving frame can be conveniently moved to the side where the substrate is less rolled up, and at this time, by rotating the second adjusting rod, the rotating second adjusting rod cooperates with the first bevel gear and the second bevel gear to drive the first adjusting rod to rotate, so that the two air guide frames can gradually approach the substrate to be coated, and at this time, the upper air guide frame is connected to the existing suction equipment, and the lower air guide frame is connected to the existing high-temperature gas conveying equipment, and then the substrate to be coated with the coating material is continuously heated and dried through the lower air guide frame, and at the same time, the upper air guide frame can extract the evaporated excess water, so as to accelerate the shaping adsorption of the coating material; S3, double-sided treatment: after the coating of one side of the hydrophilic film material is completed, the driving motor is controlled to start, so that the driving motor can drive the linkage wheel to rotate, and then the rotating linkage wheel can drive the rotating frame to rotate, and the rotating rotating frame can interchange the positions of the winding shafts on both sides, so as to realize the flipping adjustment of the substrate to be coated, and then the linkage motor is controlled to start, so as to ensure that the substrate to be coated with more winding can be continuously transported to the side with less winding, so as to complete the double-sided coating of the substrate to be coated. In this process, since the coating surface of the substrate to be coated is always located at the top, the material storage frame can better coat the coating, and at the same time, by rotating the push rod, the push rod can move the adjustment moving sheet, so that the moving sheet can cooperate with the fixed sheet to limit the two sides of the substrate to be coated, so as to ensure that the coating can be more fully coated. At the same time, with the rotation of the winding shaft, the winding amount of the two substrates to be coated is constantly changing. In this process, the driving motor is controlled to start, so that the driving motor can control the use angle of the adjusting rotating frame through the linkage wheel, so as to ensure that the top of the substrate to be coated can be at a relatively gentle angle, so as to ensure the uniform coating of the coating.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In the present invention, when in use, one end of the telescopic tube is fixedly connected to the air guide tube located above, and at the same time, one end of the existing coating material conveying tube is fixedly connected to one end of the injection tube. According to the actual width of the substrate to be coated, the number of extension shafts, adjustment tubes and sleeves is increased or decreased, so that the spliced ​​winding shaft and extension shaft can carry the sleeves after the number is adjusted, and then the spliced ​​splint can fully support the support tube and the adjustment tube, and the substrate to be coated is wound around the outer surface of the support tube and the adjustment tube on one side, so that the equipment can carry substrates of different sizes, and then one end of the substrate to be coated is wound around the outer surface of the support tube and the adjustment tube on the other side, and then when the linkage motor is controlled to start The linkage motor cooperates with the linkage shaft to drive the two linkage worms to rotate, and then the rotating linkage worms cooperate with the linkage worm gears to synchronously drive the winding shafts on both sides to rotate synchronously, and then the substrate to be coated on the side with more winding can be transported to the side with less winding for winding. In this process, the control motor located at the top is controlled to start, so that the control motor can drive the corresponding control rod to rotate, and the rotating control rod can adjust the bottom of the material storage frame located at the top to gradually fit the top of the substrate to be coated, and then the coating material can be continuously injected into the material storage frame through the existing coating material conveying pipe, and under the action of the first adjusting gear, the second adjusting gear and the two adjusting bevel gears, the rotating linkage shaft The reciprocating screw rod can be driven to rotate synchronously, and the rotating reciprocating screw rod can drive the diaphragm to move back and forth between the two first one-way valves. When the diaphragm moves from the upper first one-way valve to the lower first one-way valve, the space above the sealing frame gradually increases, and at the same time, the space below the sealing frame gradually decreases. In the process of gradually increasing the space above the sealing frame, the first one-way valve located at the upper side draws outside air into the space above the sealing frame, and at the same time, the second one-way valve located at the upper side can prevent the air inside the extension tube from being injected into the sealing frame. In the process of gradually decreasing the space below the sealing frame, the first one-way valve located at the lower side can prevent the air inside the sealing frame from being discharged, and the second one-way valve located at the lower side can fill the sealing frame with air. The air below is gradually transported to the inside of the extension tube, and then during the reciprocating movement of the partition, the air in the internal space of the sealing frame can be continuously injected into the extension tube, and then the injected flowing air can be injected into the air guide tube located above through the telescopic tube, and then the flowing air can transport the synchronously injected coating material to the inside of the storage frame, and the coating material injected into the storage frame gradually fills the space inside the storage frame and below the sealing plate, and then the coating material can be discharged through the discharge hole and transported to the top of the substrate to be coated. At the same time, under the extrusion of the bottom of the sealing frame, the coating material can be evenly coated on the top of the substrate to be coated, so that the equipment can efficiently perform fast and uniform coating processing of the coating.

[0016] (2) In the present invention, by controlling and starting the moving motor, the moving motor can drive the first moving rod to rotate, and the rotating first moving rod can move and adjust the use position of the moving frame, so that the moving frame can be easily moved to the side where the substrate is less rolled up. At this time, by rotating the second adjusting rod, the rotating second adjusting rod cooperates with the first bevel gear and the second bevel gear to drive the first adjusting rod to rotate, so that the two air guide frames can gradually approach the substrate to be coated. At this time, the air guide frame located at the top is connected to the existing suction equipment, and the air guide frame located at the bottom is connected to the existing high-temperature gas conveying equipment, and then the substrate to be coated with the coating material is continuously heated and dried through the air guide frame located at the bottom. At the same time, the air guide frame located at the top can extract the evaporated excess water, thereby accelerating the shaping adsorption of the coating material, and then the substrate to be coated can be quickly coated with the hydrophilic film material during the winding and conveying process.

[0017] (3) In the present invention, after the coating of the hydrophilic film material on one side is completed, the driving motor is controlled to be started, so that the driving motor can drive the linkage wheel to rotate, and then the rotating linkage wheel can drive the rotating frame to rotate. The rotating rotating frame can interchange the positions of the winding shafts on both sides, thereby realizing the flipping adjustment of the substrate to be coated, and then the linkage motor is controlled to be started to ensure that the substrate to be coated with more winding can be continuously transported to the side with less winding, thereby completing the double-sided coating of the substrate to be coated. In this process, since the coating surface of the substrate to be coated is always located at the top, the material storage frame can better carry out the coating. Coating, and at the same time, by rotating the push rod, the push rod can move the adjusting movable plate, and then the movable plate can cooperate with the fixed plate to limit the two sides of the substrate to be coated, thereby ensuring that the coating can be more fully coated, and at the same time, with the rotation of the winding shaft, the winding amount of the two substrates to be coated is constantly changing. In this process, by controlling the start of the drive motor, the drive motor can control the use angle of the rotating frame through the linkage wheel, thereby ensuring that the top of the substrate to be coated can be at a relatively gentle angle, thereby ensuring uniform coating of the coating, so that the equipment can efficiently and conveniently carry out efficient coating of hydrophilic film materials.

[0018] (4) In the present invention, under the action of the limit groove, the rotating winding shaft and the extension shaft can drive the sleeve to rotate synchronously, and at the same time, by rotating the second connecting gear, the second linkage gear can cooperate with the first linkage gear to drive the two-way threaded rod to rotate synchronously, so that the rotating two-way threaded rod can move and adjust the distance between the corresponding two moving blocks, and then the extension bar can support the use height of the adjustment clamp, so that the clamp can squeeze and fix the spliced ​​support tube and the adjustment tube, so as to facilitate the winding and carrying of the substrate to be coated. At the same time, under the action of the slot at one end of the extension rod, it is convenient to splice and use multiple two-way threaded rods, so as to facilitate the processing of substrates to be coated with different sizes, thereby improving the wide range of practical use of the equipment.

In this process, the control motor 126 located at the top is controlled to be started, so that the control motor 126 can drive the corresponding control rod 125 to rotate, and the rotating control rod 125 can adjust the bottom of the storage frame 129 located at the top to gradually fit the top of the substrate to be coated, and then through the existing coating material The conveying pipe can continuously inject the coating material into the storage frame 129, and under the action of the first adjusting gear 117, the second adjusting gear and the two adjusting bevel gears, the rotating linkage shaft 114 can synchronously drive the reciprocating screw 119 to rotate, and the rotating reciprocating screw 119 can drive the diaphragm 120 to reciprocate between the two first one-way valves 121. When the diaphragm 120 moves from the upper first one-way valve 121 to the lower first one-way valve 121, the space above the sealing frame 118 gradually increases, and at the same time, the space below the sealing frame 118 gradually decreases. In the process of gradually increasing the space above the sealing frame 118, the first one-way valve 121 located at the top draws outside air into the space above the sealing frame 118, and at the same time, the second one-way valve located at the top The first one-way valve 122 can prevent the air inside the extension tube 123 from being injected into the sealing frame 118. In the process of the space below the sealing frame 118 gradually shrinking, the first one-way valve 121 located at the bottom can prevent the air inside the sealing frame 118 from being discharged. The second one-way valve 122 located at the bottom can gradually transport the air below the sealing frame 118 to the extension tube 123. In the process of the reciprocating movement of the diaphragm 120, the air in the internal space of the sealing frame 118 can be continuously injected into the extension tube 123, and then the injected flowing air can be injected into the air guide tube 136 located at the top through the telescopic tube 124, so that the flowing air can transport the synchronously injected coating material to the inside of the storage frame 129. The coating material injected into the storage frame 129 gradually fills the inside of the storage frame 129. The space inside the material storage frame 129 and below the sealing plate 138 is filled, so that the coating material can be discharged through the discharge hole and transported to the top of the substrate to be coated. At the same time, under the extrusion of the bottom of the sealing frame 118, the coating material can be evenly coated on the top of the substrate to be coated. By controlling the start of the moving motor 102, the moving motor 102 can drive the first moving rod 103 to rotate.

At this time, by rotating the second adjusting rod, the rotating second adjusting rod cooperates with the first bevel gear and the second bevel gear to drive the first adjusting rod 107 to rotate, so that the two air guide frames 108 can gradually approach the substrate to be coated.At this time, the air guide frame 108 located at the top is connected to the existing suction equipment, and the air guide frame 108 located at the bottom is connected to the existing high-temperature gas conveying equipment, and then the substrate to be coated with the coating material is continuously heated and dried through the air guide frame 108 located at the bottom. At the same time, the air guide frame 108 located at the top can extract the evaporated excess water, thereby accelerating the shaping adsorption of the coating material, and then the substrate to be coated can be quickly coated with the hydrophilic film material during the winding and conveying process. After the coating of the hydrophilic film material on one side is completed, the driving motor 127 is controlled to be started, so that the driving motor 127 can drive the linkage wheel 128 to rotate, and then the rotating linkage wheel 128 can drive the rotating frame 109 to rotate. The rotating rotating frame 109 can interchange the positions of the winding shafts 110 on both sides, thereby realizing the turning over and adjustment of the substrate to be coated, and then controlling the starting of the linkage motor 116 to ensure that more substrate to be coated is wound up. The cloth substrate can be continuously conveyed to the side with less winding, so as to complete the double-sided coating of the substrate to be coated. In this process, since the coating surface of the substrate to be coated is always located at the top, the material storage frame 129 can better coat the coating. At the same time, by rotating the push rod 131, the push rod 131 can move the adjustment moving sheet 132, so that the moving sheet 132 can cooperate with the fixed sheet 130 to limit the two sides of the substrate to be coated, so as to ensure that the coating can be more fully coated. At the same time, with the rotation of the winding shaft 110, the winding amount of the two substrates to be coated is constantly changing. In this process, by controlling the start of the drive motor 127, the drive motor 127 can control the use angle of the adjustment rotating frame 109 through the linkage wheel 128, so as to ensure that the top of the substrate to be coated can be at a relatively gentle angle, so as to ensure the uniform coating of the coating, so that the equipment can efficiently and conveniently carry out efficient coating of the hydrophilic film material; See also Figure 13-Figure 15, the support mechanism 2 is provided with two groups, each group of the support mechanism 2 includes a sleeve 201, two support tubes 207 and an adjusting tube 208, the sleeve 201 is slidably sleeved on the outer surfaces of the corresponding reel 110 and the extension shaft 111, the outer surface of the sleeve 201 is rotatably connected with three bidirectional threaded rods 203, the outer surface of each bidirectional threaded rod 203 is threadedly connected with two moving blocks 204, the top of each moving block 204 is rotatably connected with an extension bar 205, the six extension bars 205 are divided into three groups, and a clamping plate 206 is rotatably connected between one end of each group of two extension bars 205, the outer surface of each bidirectional threaded rod 203 is sleeved with a first linkage gear, the outer surface of the sleeve 201 is rotatably connected with a second linkage gear 202, the second linkage gear 202 and the three first linkage gears are all meshed, the adjusting tube 208 and the two support tubes 207 are slidably sleeved on the three Between the outer surfaces of the splints 206, under the action of the limit groove, the rotating winding shaft 110 and the extension shaft 111 can drive the sleeve to rotate synchronously, and at the same time, by rotating the second connecting gear, the second linkage gear 202 can cooperate with the first linkage gear to drive the two-way threaded rod 203 to rotate synchronously, so that the rotating two-way threaded rod 203 can move and adjust the distance between the corresponding two moving blocks 204, and then the extension bar 205 can support the adjustment of the use height of the splint 206, so that the splint 206 can squeeze and fix the spliced ​​support tube 207 and the adjustment tube 208, so as to facilitate the winding and carrying of the substrate to be coated. At the same time, under the action of the slot at one end of the extension rod, it is convenient to splice and use multiple two-way threaded rods 203, so as to facilitate the processing of substrates to be coated of different sizes, thereby improving the wide range of practical use of the equipment.

According to the actual width of the substrate to be coated, increase or decrease the number of extension shafts 111, adjustment tubes 208 and sleeves 201, so that the spliced ​​winding shaft 110 and extension shaft 111 can carry the sleeves 201 after the number is adjusted, and then the spliced ​​clamping plate 206 can fully support the support tube 207 and the adjustment tube 208, and the substrate to be coated is wound around the outer surface of the support tube 207 and the adjustment tube 208 on one side, so that the equipment can carry substrates of different sizes, and then one end of the wound substrate to be coated is wound around the support tube 207 and the adjustment tube 208 on the other side. The outer surface of the joint tube 208, and then when the linkage motor 116 is controlled to be started, the linkage motor 116 cooperates with the linkage shaft 114 to drive the two linkage worms 115 to rotate, and then the rotating linkage worm 115 cooperates with the linkage worm wheel to synchronously drive the winding shafts 110 on both sides to rotate synchronously, and then the substrate to be coated on the side with more winding can be transported to the side with less winding for winding. In this process, the control motor 126 located at the top is controlled to be started, so that the control motor 126 can drive the corresponding control rod 125 to rotate, and the rotating control rod 125 can adjust the bottom of the storage frame 129 located at the top to gradually fit the top of the substrate to be coated, and then the coating material can be continuously injected into the storage frame 129 through the existing coating material conveying pipe, and in the first Under the action of the first adjusting gear 117, the second adjusting gear and the two adjusting bevel gears, the rotating linkage shaft 114 can synchronously drive the reciprocating screw rod 119 to rotate, and the rotating reciprocating screw rod 119 can drive the diaphragm 120 to move back and forth between the two first one-way valves 121. When the diaphragm 120 moves from the upper first one-way valve 121 to the lower first one-way valve 121, the space above the sealing frame 118 gradually increases, and the space below the sealing frame 118 gradually decreases. In the process of gradually increasing the space above the sealing frame 118, the first one-way valve 121 located at the top draws the outside air into the space above the sealing frame 118, and the second one-way valve 122 located at the top can prevent the air inside the extension tube 123 from being injected into the sealing frame 1 18. In the process of the space below the sealing frame 118 gradually shrinking, the first one-way valve 121 located at the bottom can prevent the air inside the sealing frame 118 from being discharged, and the second one-way valve 122 located at the bottom can gradually transport the air below the sealing frame 118 to the extension tube 123, and then in the process of the reciprocating movement of the partition 120, the air in the internal space of the sealing frame 118 can be continuously injected into the extension tube 123, and then the injected flowing air can be injected into the air guide tube 136 located at the top through the telescopic tube 124, and then the flowing air can transport the synchronously injected coating material to the inside of the storage frame 129, and the coating material injected into the storage frame 129 gradually fills the space inside the storage frame 129 and below the sealing plate 138.Then, the coating material can be discharged through the discharge hole and transported to the top of the substrate to be coated, and at the same time, the coating material can be evenly coated on the top of the substrate to be coated under the extrusion of the bottom of the sealing frame 118; Step 2, shaping treatment: by controlling and starting the moving motor 102, the moving motor 102 can drive the first moving rod 103 to rotate, and the rotating first moving rod 103 can move and adjust the use position of the moving frame 104, so that the moving frame 104 can be easily moved to the side where the substrate is less rolled up. At this time, by rotating the second adjusting rod, the rotating second adjusting rod cooperates with the first bevel gear and the second bevel gear to drive the first adjusting rod 107 to rotate, so that the two air guide frames 108 can gradually approach the substrate to be coated. At this time, the upper air guide frame 108 is connected to the existing suction equipment, and the lower air guide frame 108 is connected to the existing high-temperature gas conveying equipment, and then the substrate to be coated with the coating material is continuously heated and dried through the lower air guide frame 108. At the same time, the upper air guide frame 108 can extract the evaporated excess water, thereby accelerating the shaping adsorption of the coating material, and then the substrate to be coated can be quickly coated with the hydrophilic film material during the winding and conveying process. Step 3, double-sided treatment: After the coating of the hydrophilic film material on one side is completed, the driving motor 127 is controlled to be started, so that the driving motor 127 can drive the interlocking wheel 128 to rotate, and then the rotating interlocking wheel 128 can drive the rotating frame 109 to rotate, and the rotating rotating frame 109 can interchange the positions of the winding shafts 110 on both sides, so as to realize the turning adjustment of the substrate to be coated, and then control the starting of the interlocking motor 116 to ensure that the substrate to be coated with more winding can be continuously transported to the side with less winding, so as to complete the double-sided coating of the substrate to be coated. In this process, since the coating surface of the substrate to be coated is always located at the top, the storage frame 129 can better coat the coating. At the same time, by rotating the push rod 131, the push rod 131 can move the adjustment moving plate 132, and then the moving plate 132 can cooperate with the fixed plate 130 to limit the two sides of the substrate to be coated, thereby ensuring that the coating can be more fully coated. At the same time, with the rotation of the winding shaft 110, the winding amount of the two substrates to be coated is constantly changing. In this process, by controlling the start of the drive motor 127, the drive motor 127 can control the use angle of the adjustment rotating frame 109 through the linkage wheel 128, thereby ensuring that the top of the substrate to be coated can be at a relatively gentle angle, thereby ensuring the uniform coating of the coating, so that the equipment can efficiently and conveniently carry out efficient coating of the hydrophilic membrane material.

At the same time, by rotating the push rod (131), the push rod (131) can move the adjustment moving plate (132), and then the moving plate (132) can cooperate with the fixed plate (130) to limit the two sides of the substrate to be coated, thereby ensuring that the coating can be applied more fully. At the same time, as the winding shaft (110) rotates, the winding amount of the two substrates to be coated is constantly changing. In this process, the driving motor (127) is controlled to start, and then the driving motor (127) can control the use angle of the adjustment rotating frame (109) through the linkage wheel (128), thereby ensuring that the top of the substrate to be coated can be at a relatively gentle angle, thereby ensuring uniform coating of the coating.
