Description

Technical Field

[0001] The present invention relates to the technical field of processing filter components, in particular to a feeding mechanism and a feeding method for a spacer net, a diaphragm and a guide cloth of a filter element. Background Art

[0002] As people's demands for drinking water quality increase, pure water systems are gradually becoming part of every household's drinking water system. Currently, water purifiers on the market generally utilize reverse osmosis membrane filters (also known as RO membrane filters). RO filters can filter impurities such as organic matter, colloids, bacteria, and viruses from raw water, and are particularly efficient at filtering inorganic salts, heavy metals, and other impurities. Therefore, RO filters constitute the core component of water purifiers, and the filtration performance of water purifiers is directly related to the filtration performance of the RO filter.

[0003] A common RO membrane filter element includes a central tube and a reverse osmosis membrane unit wound on the central tube, wherein the reverse osmosis membrane unit is formed by stacking several layers of cut spacers, membranes and guide cloths.

[0004] In existing technology, separate screen cutting devices, membrane cutting devices, and guide cloth cutting devices are typically used. Separator screen rolls, membrane rolls, and guide cloth rolls are then cut and segmented separately. The cut screens, membranes, and guide cloths are then manually stacked to form reverse osmosis membrane units. This prevents continuous feeding and stacking, resulting in a low degree of automation and a time-consuming and labor-intensive process. Summary of the Invention

[0005] The present invention aims to provide a feeding mechanism and method for the filter element's screen, membrane, and guide cloth, which have a reasonable layout, sequential feeding, a high degree of automation, and time and labor savings. Another object of the present invention is to provide a feeding method for the filter element's screen, membrane, and guide cloth, which also achieves orderly feeding.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a feeding mechanism for the separator, diaphragm and guide cloth of a filter element, comprising a frame, on which a plurality of material reels and a feeding motor for driving the material reels to rotate are sequentially arranged from top to bottom; the frame comprises a platform, on which a first placement table and a second placement table are arranged, the first placement table and the second placement table forming a conveying channel; the platform is provided with a separator feeding and cutting device, a diaphragm feeding and cutting device, and a guide cloth feeding and cutting device provided in a lifting manner; the separator feeding and cutting device and the diaphragm feeding and cutting device are arranged at the feeding end of the first placement table, and the guide cloth feeding and cutting device is arranged between the first placement table and the second placement table;

[0007] The frame is equipped with a first manipulator and a third manipulator for movement, the platform is equipped with a second manipulator for movement, and the third manipulator moves back and forth above the first and second placement tables. The first manipulator is used to grab the cut partition nets, the second manipulator is used to pull the membrane, and the third manipulator is used to grab the guide cloth and move the stacked partition nets and membranes.

[0008] The frame is also equipped with a deviation correction device to control the displacement of the material reel.

[0009] By adopting the above technical solution, before feeding, the separation mesh material roll, membrane material roll and guide cloth material roll are respectively installed on the material reel, and the three are arranged in order from top to bottom. The second robot grabs the front end of the membrane and conveys and cuts it through the membrane feeding and cutting device, and then places it on the first placement table. Then the separation mesh material roll is conveyed and cut by the separation mesh feeding and cutting device. The first robot stacks the cut separation mesh on the cut membrane to form a preliminary filtration unit. At this time, the guide cloth feeding and cutting device is located below the platform, and the third robot moves the preliminary filtration unit from the first placement table to the second placement table; then, the guide cloth feeding and cutting device rises relative to the platform, and the guide cloth is conveyed and cut by the guide cloth feeding and cutting device. The third robot stacks the cut guide cloth on the preliminary filtration unit to form a reverse osmosis membrane unit. The guide cloth feeding and cutting device descends and resets, clearing the third robot. The third robot then moves horizontally above the first placement table, ready to pick up the next preliminary filter unit. This facilitates the feeding of the screen, membrane, and guide cloth. All three materials are fed sequentially and orderly along the same conveyor channel, eliminating the need for manual stacking of the three cut materials. This streamlined layout offers a high degree of automation and saves time and effort. A deviation correction device ensures accurate alignment of the three materials during feeding and stacking.

[0010] The present invention is further configured as follows: the mesh feeding and cutting device includes a first fixed frame, the first fixed frame is fixedly mounted on the frame, a feeding platform is provided between the feeding end and the discharging end of the first fixed frame, an automatic feeding assembly, a first clamping assembly and a first cutting assembly are provided on the first fixed frame, the first clamping assembly and the first cutting assembly are arranged at the discharging end of the feeding platform; the first cutting assembly includes a rodless cylinder, a cutter disc frame, a cutter disc rotatably arranged on the cutter disc frame and a first motor driving the cutter disc to rotate, and the rodless cylinder drives the cutter disc frame to move horizontally.

[0011] By adopting the above technical solution, during the feeding process of the partition net, under the action of the automatic feeding assembly, the partition net is transported from the feeding end to the discharging end. When it is transported to a certain length, the first clamping assembly presses down to clamp the partition net and fix it on the feeding platform. At this time, the automatic feeding assembly stops feeding, and the first cutting assembly starts. The rodless cylinder moves to drive the cutter disc frame to move along the width direction of the partition net, and the first motor drives the cutter disc to rotate. In this way, when the cutter disc moves horizontally, the high-speed rotating cutter disc can cut the partition net at the discharging end. Since the partition net is clamped and fixed by the first clamping assembly during cutting, on the one hand, it can prevent the partition net from shifting during cutting, and on the other hand, it can prevent the remaining partition net from sliding off the feeding platform after cutting. In this way, the cut edges of the partition net are smoother and have a better cutting effect. When cutting is completed, the first clamping assembly resets, and the automatic feeding assembly restarts feeding, which can push the subsequent partition net out of the discharging end, making it easier for the first manipulator to pull the partition net out.

[0012] The present invention is further configured as follows: the automatic feeding assembly includes an active roller, a driven roller and a driving motor for driving the active roller to rotate; the active roller is rotatably connected to a first fixed frame; a downward pressure cylinder is provided on the first fixed frame; a mounting frame is provided on the piston rod of the downward pressure cylinder; the driven roller is rotatably connected to the mounting frame; a gap is formed between the active roller and the driven roller; the first clamping assembly includes a first clamping cylinder and a first clamping block provided on the piston rod of the first clamping cylinder; the first clamping block is clamped together with the feeding platform.

[0013] By adopting the above technical solution, when the automatic feeding assembly conveys the screen forward, the screen passes through the gap between the active roller and the driven roller, the driving motor drives the active roller to rotate, and the downward pressure cylinder drives the driven roller on the mounting frame to press down on the active roller, so that the driven roller presses the screen against the active roller. Due to the large friction between the screen and the active and driven rollers, the screen can be conveyed forward when the active roller rotates. When conveying stops, the first pressing cylinder is activated, driving the first pressing block to move toward the feeding platform, thereby pressing and fixing the screen on the feeding platform. At the same time, the downward pressure cylinder drives the driven roller to lift up, thereby stopping feeding.

[0014] The present invention is further configured as follows: the diaphragm feeding and cutting device includes a second fixed frame, the second fixed frame is arranged below the partition mesh feeding and cutting device, the second fixed frame is provided with a conveying platform, and the conveying platform is provided with a material pressing and positioning assembly; the discharge end of the second fixed frame is provided with a front pushing frame through a sliding assembly, and the front pushing frame is provided with a second cutting assembly and a second clamping assembly, the second clamping assembly includes a second clamping cylinder arranged on the front pushing frame, the piston rod of the second clamping cylinder is provided with a second clamping block, the front pushing frame is provided with a horizontal platform surface, and the second clamping block is pressed and matched with the horizontal platform surface; the second fixed frame is provided with a front pushing cylinder, and the piston rod of the front pushing cylinder is fixedly connected to the front pushing frame.

[0015] By adopting the above technical solution, during the diaphragm feeding process, the pressing material positioning assembly is lifted up so that the diaphragm can move relative to the conveying platform, the material reel is gradually unloaded, the second manipulator grabs the front end of the diaphragm that is partially extended from the front push frame, and the second clamping cylinder drives the piston rod to reset, so that the second clamping block is away from the horizontal platform surface. At this time, the diaphragm is no longer subjected to the clamping force of the second clamping block, and the second manipulator can pull the diaphragm forward. When it is pulled out to an appropriate length, the pressing material positioning assembly and the second clamping block re-press and position the diaphragm front and back, and the second cutting assembly cuts the diaphragm. After the cutting is completed, the pressing material positioning assembly is lifted up and released. In addition to the clamping effect, the front push cylinder is started and pushes the front push frame to move forward relative to the second fixed frame. Since the second clamping block clamps the diaphragm in position at this time, the front push frame can also drive the diaphragm forward one end distance while moving forward. Subsequently, the material pressing and positioning assembly presses and positions the diaphragm again, and the second clamping block resets to release the diaphragm. When the front push cylinder is reset, it can drive the front push frame to move backward and reset. In this way, it can be ensured that a section of the diaphragm is left after cutting and extends out of the second cutting assembly, which is convenient for the second manipulator to pull the material later, and the cutting can be carried out close to the second clamping block, the cutting is smoother, and the cutting effect is better.

[0016] The present invention is further configured as follows: the pressing positioning assembly includes a pressing cylinder and a pressing spring piece, the pressing cylinder is fixedly mounted on the second fixed frame, a pressing block is provided on the piston rod of the pressing cylinder, and the pressing block is tightly fitted with the conveying platform; a plurality of fixed blocks are provided on the conveying platform, and the arc-shaped pressing spring piece is provided on the fixed block, and the lowest point of the pressing spring piece is in contact with the conveying platform.

[0017] By adopting the above technical solution, when the diaphragm stops feeding, the pressing cylinder drives the pressing block on the piston rod to move downward, so that the lower surface of the pressing block can press the diaphragm tightly and fix it on the conveying platform; when the diaphragm is feeding, the side of the diaphragm can be pressed tightly on the conveying platform under the elastic force of the pressing spring sheet. In this way, the diaphragm is not easy to warp or deflect during the feeding process, and the feeding is smoother.

[0018] The present invention is further configured as follows: the sliding assembly includes a slide rail fixedly arranged on the second fixed frame, and a slider slidably arranged on the slide rail, the slide rail extends along the material transmission direction, and the slider is fixedly connected to the bottom of the front push frame.

[0019] By adopting the above technical solution, when the front push cylinder pushes the front push frame to move, the slider moves along the slide rail, so that the front push frame can slide smoothly.

[0020] The present invention is further configured as follows: the guide cloth feeding and cutting device includes a tension control component and a lifting platform, and the frame is provided with a lifting electric cylinder; the lifting platform is provided with an automatic feeding component and a cutting knife component, and the lifting electric cylinder drives the lifting platform to rise and fall; a mounting plate is provided on the frame, and a plurality of guide holes are opened on the mounting plate, and a plurality of guide rods are provided on the lifting platform, and the guide rods are guided and matched with the guide holes.

[0021] By adopting the above technical solution, when the guide cloth is needed, the lifting cylinder is activated, driving the lifting platform to rise. Then, the automatic feeding assembly is activated to feed the guide cloth forward. The front end of the guide cloth is grasped by the third robot. After feeding a certain length, the cutting assembly cuts the guide cloth, and the third robot can take the cut guide cloth away. Subsequently, when the third robot needs to return to grab the stacked separators and membranes, the lifting cylinder drives the lifting platform to descend, thereby forming a avoidance for the third robot as it passes. At this time, the automatic feeding assembly stops feeding. The cooperation between the guide rods and guide holes can make the lifting process of the lifting platform more stable. In addition, the mounting plate can also limit the position of the lifting platform's descent. When the lifting platform descends to the bottom surface and contacts the mounting plate, the lifting platform stops descending. As the guide cloth is gradually unwound, the roll diameter gradually decreases. The control function of the tension control assembly can gradually increase the speed of the material reel to keep the tension constant. In this way, during the feeding process, it is possible to avoid the third robot arm and also ensure that the material roll is always in a tensioned state during the feeding process, thereby improving the cutting effect.

[0022] The present invention is further configured as follows: a tension control assembly includes a tension sensor, a first tensioning roller and a second tensioning roller, an intermediate roller is arranged between the first tensioning roller and the second tensioning roller, the intermediate roller is arranged on the tension sensor through a mounting seat, and the axes of the first tensioning roller, the second tensioning roller and the intermediate roller are parallel; one end of the material reel is fixedly connected to a magnetic powder brake, and the tension sensor is controlled and coordinated with the magnetic powder brake; an upper cylinder is arranged below the first tensioning roller, and the piston rod of the upper cylinder is provided with an upper block, and the upper block is abutted and coordinated with the first tensioning roller.

[0023] By adopting the above technical solution, the guide cloth passes around the first tensioning roller, the middle roller and the second tensioning roller in sequence, the lower surface of the guide cloth is attached to the outer wall of the middle roller, and the upper surface of the guide part is attached to the outer walls of the first tensioning roller and the second tensioning roller. During the unwinding process, the tension sensor detects the unwinding tension through the intermediate shaft, and controls the unwinding speed of the material reel through the magnetic powder brake, so that the tension of the guide cloth is constant and can always be in a tensioned state.

[0024] The present invention is further configured as follows: a flattening table is provided under the platform of the frame, the flattening table is provided between the material reel and the tension control component, the feed end of the flattening table is provided with a feed roller, and the discharge end of the flattening table is provided with a discharge roller; the deviation correction device includes a deviation correction detector and a deviation correction adjustment component, the deviation correction adjustment component includes a deviation correction electric cylinder, the deviation correction electric cylinder is connected to the material reel, and the deviation correction detector and the deviation correction electric cylinder control and cooperate to drive the material reel to move axially.

[0025] By adopting this technical solution, the guide fabric is unwound from the roll and passed onto the flattening table. When laid flat on the flattening table, it stretches the fabric to a certain extent, reducing curling after cutting and facilitating stacking in subsequent processes. Furthermore, during the feeding process, a web-correction detector continuously monitors the edge of the guide fabric. If the web-correction detector detects a deviation in the width direction of the guide fabric, it sends a signal to the web-correction electric cylinder, which activates it and drives the web-correction roll on it along the width direction via the material reel to adjust its position.

[0026] Another technical purpose of the present invention is achieved by the following technical solution: a feeding method for the feeding mechanism of the filter element's spacer, diaphragm, and guide cloth comprises the following steps:

[0027] S1. Loading: Install the screen roll, membrane roll, and guide fabric roll on the material reel, and arrange them in order from top to bottom. Pass the front end of the screen roll into the screen feeding and cutting device, the front end of the membrane into the membrane feeding and cutting device, and the front end of the guide fabric into the guide fabric feeding and cutting device;

[0028] S2. Film feeding and cutting: The second manipulator grabs the film at the discharge end of the film feeding and cutting device, moves and pulls out the film of appropriate length, and then cuts the film roll into individual films, which fall onto the first placement table.

[0029] S3, mesh feeding and cutting: The first manipulator grabs the front end of the mesh fed from the mesh feeding and cutting device, moves and pulls out the mesh of appropriate length, and then cuts the mesh roll into single sheets;

[0030] S4. Stacking and transferring: The first manipulator moves the screen onto the single membrane sheet on the first placement table, so that the screen is stacked on the membrane sheet to form a preliminary filtration unit. The third manipulator transfers the preliminary filtration unit to the second placement table.

[0031] S5, lifting material: the lifting electric cylinder drives the guide cloth feeding and cutting device to rise relative to the platform;

[0032] S6. Feeding and cutting the guide cloth: The third robot grabs the front end of the guide cloth delivered from the guide cloth feeding and cutting device, moves and pulls out the guide cloth of appropriate length, and then cuts the guide cloth roll into single sheets;

[0033] S7, stacking the guide cloth: The third manipulator drives the guide cloth to move horizontally above the primary filtration unit, and stacks the guide cloth on the primary filtration unit to form a reverse osmosis membrane unit;

[0034] S8, avoidance: the lifting electric cylinder drives the guide cloth feeding and cutting device to descend relative to the platform to avoid the third manipulator, and the third manipulator is reset to above the first placement table.

[0035] By adopting the above technical solution, the diaphragm, the partition net and the guide cloth are fed sequentially in a three-in-one manner on the same rack, and are transported on the conveying channel formed between the first placement table and the second placement table, so that the diaphragm, the partition net and the guide cloth can be stacked neatly and orderly.

[0036] In summary, the present invention has the following beneficial effects:

[0037] 1. The machine frame is equipped with a screen feeding and cutting device, a membrane feeding and cutting device, and a guide cloth feeding and cutting device. The guide cloth feeding and cutting device is arranged to avoid the feed on the conveying channel. This facilitates the feeding of the screen, membrane, and guide cloth. The three materials are fed sequentially and orderly on the same conveying channel, eliminating the need for manual stacking of the three cut materials. The layout is reasonable, with a high degree of automation and greater time and labor savings. The deviation correction device ensures the alignment accuracy of the three materials during feeding and stacking.

[0038] 2. The front push frame is used to drive the cut film to send a certain amount of excess forward, which is convenient for the second manipulator to pull the material later. The cutting can be carried out close to the second pressing block, which makes the cutting smoother and has a better cutting effect.

[0039] 3. An automatic feeding assembly, a first pressing assembly, and a first cutting assembly are arranged on a fixed frame, and a cutter disc is used for cutting. The cut edges of the screen are smoother, achieving better cutting effects. When cutting is completed, the first pressing assembly is reset, and the automatic feeding device restarts feeding, pushing the subsequent screens out of the discharge end, making it easier for the first manipulator to pull the screens out.

[0040] 4. The lifting electric cylinder is used to control the lifting of the lifting platform to avoid the third manipulator in the process of grabbing different fabrics. As the guide fabric is gradually unwound, the roll diameter of the material roll gradually decreases. The speed of the material roll can be gradually adjusted through the control of the tension control component to keep the tension constant, so that the material roll can always be in a tensioned state during the feeding process.

DETAILED DESCRIPTION

[0054] The present invention will be further described below with reference to the accompanying drawings.

[0055] The feeding mechanism and feeding method of the filter element's spacer, diaphragm, and guide cloth, such as Figure 1 and Figure 2As shown, the machine comprises a frame 1, with three material reels 11 provided at the initial end thereof. The three material reels 11 are arranged in sequence in the vertical direction. The upper material reel 11 is used to place a screen material reel 111, the middle material reel 11 is used to place a membrane material reel 112, and the lower material reel 11 is used to place a guide fabric reel 113. Each end of the material reel 11 is connected to a feed motor 12, which drives the material reel 11 to rotate. The feed motor 12 is slidably mounted on the frame 1 via a slide rail assembly. The frame 1 includes a platform, on which are correspondingly provided a screen feed cutting device 2, a membrane feed cutting device 3, and a guide fabric feed cutting device 4. The screen feed cutting device 2 and the membrane feed cutting device 3 are arranged at the feed end of the first placement table 13. The frame 1 is provided with a first manipulator 15 and a third manipulator 17 for movement, and the platform is provided with a second manipulator 16 for movement. The front end of the mesh material roll 111 passes through the mesh feeding and cutting device 2, and is fed through the mesh feeding and cutting device 2. The material is also pulled by the first manipulator 15 while feeding; the front end of the film material roll 112 passes through the film feeding and cutting device 3, and is fed through the film feeding and cutting device 3. The material is also pulled by the second manipulator 16 while feeding. The film feeding and cutting device 3 is located between the mesh feeding and cutting device 2 and the mesh feeding and cutting device 2. ; the diaphragm and the partition are fed from the platform of the frame 1, while the guide cloth is fed from the bottom of the platform. A first placement table 13 and a second placement table 14 are provided on the platform. A conveying channel is formed between the first placement table 13 and the second placement table 14. A lifting through hole 18 is provided on the platform between the first placement table 13 and the second placement table 14. The guide cloth feeding device 14 is lifted and lowered at the lifting through hole 18, and the third manipulator 17 moves horizontally above the first placement table 13 and the second placement table 14.

[0056] like Figure 5-7As shown, the mesh feeding and cutting device 2 includes a first fixed frame 21, which is fixedly mounted on the frame 1, and a feeding platform 22 is provided between the feeding end and the discharging end of the first fixed frame 21, and an automatic feeding component, a first pressing component and a first cutting component are provided on the first fixed frame 21, and the first pressing component and the first cutting component are provided at the discharging end of the feeding platform 22; the automatic feeding component includes an active roller 23, a driven roller 242 and a driving motor 27 for driving the active roller 23 to rotate, the active roller 23 is rotatably connected to the first fixed frame 21, a downward pressure cylinder 24 is provided on the first fixed frame 21, a mounting frame 241 is provided on the piston rod of the downward pressure cylinder 24, the driven roller 242 is rotatably connected to the mounting frame 241, and a gap is formed between the active roller 23 and the driven roller 242. The first pressing assembly includes a first pressing cylinder 25 and a first pressing block 251 provided on the piston rod of the first pressing cylinder 25. The first pressing block 251 is tightly engaged with the feeding platform 22. The first cutting assembly includes a rodless cylinder 26, a cutter head frame 261, a cutter head 262 rotatably provided on the cutter head frame 261, and a first motor 263 driving the cutter head 262 to rotate. The rodless cylinder 26 drives the cutter head frame 261 to translate.

[0057] During the feeding process of the partition net, the partition net passes through the gap between the active roller 23 and the driven roller 242, the driving motor 27 drives the active roller 23 to rotate, and the downward pressure cylinder 24 drives the driven roller 242 on the mounting frame 241 to press down on the active roller 23, so that the driven roller 242 presses the partition net onto the active roller 23. Due to the large friction between the partition net and the active roller 23 and the driven roller 242, when the active roller 23 rotates, it can drive the partition net to be transported forward. When it is transported to a certain length, the first pressing cylinder 25 presses down, and the partition net is pressed and fixed to the feeding plane through the first pressing block 251. On the platform 22, at this time, the automatic feeding assembly stops feeding, and the first cutting assembly starts. The rodless cylinder 26 moves to drive the cutter head 261 to move along the width of the partition net, and the first motor 263 drives the cutter head 262 to rotate. In this way, when the cutter head 262 moves horizontally, the high-speed rotating cutter head 262 can cut the partition net at the discharge end. Because the partition net is pressed and fixed by the first pressing assembly during cutting, on the one hand, it can prevent the partition net from shifting during cutting, and on the other hand, it can prevent the remaining partition net from sliding off the feeding platform 22 after cutting. In this way, the cut partition net has a smoother cutting edge and better cutting effect. When cutting is completed, the first pressing cylinder 25 is reset, and the automatic feeding assembly restarts feeding, which can push the subsequent partition net out of the discharge end, making it easier for the first manipulator 15 to pull the partition net out.

[0058] like Figure 8-9As shown, the diaphragm feeding and cutting device 3 includes a second fixed frame 31, the second fixed frame 31 is arranged below the partition mesh feeding and cutting device 2, the second fixed frame 31 is provided with a conveying platform 311, the conveying platform 311 is provided with a pressing positioning assembly, the pressing positioning assembly includes a pressing cylinder 32 and a pressing spring 33, the pressing cylinder 32 is fixedly installed on the second fixed frame 31, the piston rod of the pressing cylinder 32 is provided with a pressing block 321, the pressing block 321 is tightly fitted with the conveying platform 311; a plurality of fixed blocks 34 are provided on the conveying platform 311, and an arc-shaped pressing spring 33 is provided on the fixed block 34, and the lowest point of the pressing spring 33 is in contact with the conveying platform 311. The discharge end of the second fixed frame 31 is provided with a front push frame 35 slidingly through a sliding assembly. The front push frame 35 is provided with a second cutting assembly 312 and a second pressing assembly. The second cutting assembly 312 includes a rodless cylinder and a cutter provided on the second fixed frame 31. The rodless cylinder drives the cutter to move along the width direction of the feed path. The second pressing assembly includes a second pressing cylinder 36 provided on the front push frame 35. The piston rod of the second pressing cylinder 36 is provided with a second pressing block 361. The front push frame 35 is provided with a horizontal surface 351. The second pressing block 361 is pressed tightly against the horizontal surface 351. The second fixed frame is provided with a front push cylinder 37. The piston rod of the front push cylinder 37 is fixedly connected to the front push frame 35. The sliding assembly includes a slide rail 38 fixedly provided on the second fixed frame 31 and a slider 39 slidably provided on the slide rail 38. The slide rail 38 extends along the material transmission direction. The slider 39 is fixedly connected to the bottom of the front push frame 35.

[0059] The second manipulator 16 then moves the second pressing block 361 back to the horizontal position, and the second pressing cylinder 36 drives the piston rod 36 to return to the original position, so that the second pressing block 361 is away from the horizontal platform 351. At this time, the diaphragm is no longer subjected to the pressing force of the second pressing block 361, and the second manipulator 16 can pull the diaphragm forward. When the diaphragm is pulled out to an appropriate length, the pressing cylinder 32 drives the pressing block 321 on the piston rod to move downward, so that the lower surface of the pressing block 321 can press the diaphragm and fix it on the conveying platform 311. The pressing positioning assembly and the second pressing block 361 re-press the diaphragm front and back and position it, and the second cutting assembly 312 cuts the diaphragm. After the material is completed, the material pressing and positioning assembly is lifted up to release the pressing effect, and the front pushing cylinder 37 is started. When the front pushing cylinder 37 pushes the front pushing frame 35 to move, the slider 39 moves along the slide rail 38, which can push the front pushing frame 35 to move forward relative to the second fixed frame 31. Since the second clamping block 361 clamps the diaphragm in position at this time, the front pushing frame 35 can also drive the diaphragm to move forward a distance. Subsequently, the material pressing and positioning assembly presses the diaphragm in position again, and the second clamping block 361 is reset to release the diaphragm. When the front pushing cylinder 37 is reset, the front pushing frame 35 can be driven to move backward and reset. In this way, it can be ensured that a certain amount of margin is left after the diaphragm is cut to extend out of the second cutting assembly 312, which is convenient for the second manipulator 16 to pull the material later, and it can be cut close to the second clamping block 361 during cutting, so the cutting is smoother and the cutting effect is better.

[0060] During the film feeding process, the side of the film can be pressed tightly against the conveying platform 311 under the elastic force of the pressing spring 33. In this way, the film is not easily warped or deflected during the feeding process, and the feeding is more stable.

[0061] like Figure 10-12As shown, the guide cloth feeding and cutting device 4 includes a tension control component, a lifting platform 41, and the frame 1 is provided with a lifting electric cylinder 42; the lifting platform 41 is provided with an automatic feeding component 10, a third clamping component 413 and a cutting component 412, and the lifting electric cylinder 42 drives the lifting platform 41 to rise and fall (since the structure of the automatic feeding component 10 here is the same as that of the automatic feeding component in the mesh feeding and cutting device 2, the cutting component 412 is the same as the structure of the above-mentioned second cutting component 312, and the structure of the third clamping component 413 is the same as that of the first clamping component, which will not be repeated here); a mounting plate 43 is provided on the frame 1, and a plurality of guide holes 431 are opened on the mounting plate 43, and a plurality of guide rods 411 are provided on the lifting platform 41, and the guide rods 411 are guided and matched with the guide holes 431. The tension control assembly includes a tension sensor 44, a first tensioning roller 45 and a second tensioning roller 46. An intermediate roller 47 is arranged between the first tensioning roller 45 and the second tensioning roller 46. The intermediate roller 47 is arranged on the tension sensor 44 through a mounting seat 48. The axes of the first tensioning roller 45, the second tensioning roller 46 and the intermediate roller 47 are parallel; one end of the material reel 11 is fixedly connected to the magnetic powder brake 5, and the tension sensor 44 is controlled and coordinated with the magnetic powder brake 5; an upper cylinder 49 is arranged below the first tensioning roller 45, and the piston rod of the upper cylinder 49 is provided with an upper block 491, and the upper block 491 is abutted against the first tensioning roller 45.

[0062] like Figure 10 As shown, a flattening table 6 is provided under the platform of the frame 1. The flattening table 6 is provided between the material reel 11 and the tension control component. A feed roller 61 is provided at the feed end of the flattening table 6, and a discharge roller 62 is provided at the discharge end of the flattening table 6.

[0063] After being unwound from the roll, the guide fabric is passed onto the flattening table 6. When laid flat on the flattening table 6, it stretches the fabric to a certain extent, reducing curling after cutting and facilitating stacking in subsequent processes. The fabric then passes sequentially around the first tensioning roller 45, the intermediate roller 47, and the second tensioning roller 46. The lower surface of the fabric adheres to the outer wall of the intermediate roller 47, and the upper surface of the guide portion adheres to the outer walls of the first and second tensioning rollers 45, 46. During the unwinding process, the tension sensor 44 detects the unwinding tension via the intermediate shaft and controls the unwinding speed of the material reel 11 via the magnetic powder brake 5, ensuring a constant tension on the fabric and maintaining it in a taut state.

[0064] When the guide cloth is needed, the lifting cylinder 42 is started to drive the lifting platform 41 to rise. At this time, the third pressing component 413 presses the guide cloth to position it and rises with the lifting platform 41. Then the automatic feeding component 10 is started to feed the guide cloth forward. The front end of the guide cloth is grabbed by the third manipulator 17. After a certain length is fed out, the cutting component 412 cuts the guide cloth, and the third manipulator 17 can take the cut guide cloth away. Then, when the third manipulator 17 needs to return When grabbing the stacked screens and membranes, the lifting cylinder 42 drives the lifting platform 41 down, thereby avoiding the third manipulator 17 as it passes. At this point, the automatic feeding assembly 10 stops feeding. The cooperation between the guide rod 411 and the guide hole 431 allows the lifting platform 41 to rise and fall more smoothly. Furthermore, the mounting plate 43 limits the position of the lifting platform 41. When the lifting platform 41 descends to the point where its lower surface abuts the mounting plate 43, the lifting platform 41 stops descending. As the guide cloth is gradually unwound, the roll diameter gradually decreases. The tension control assembly gradually increases the speed of the material reel 11 to maintain a constant tension. In this way, during the feeding process, the third manipulator 17 can be avoided and the material roll can be kept in a tensioned state at all times, thereby improving the cutting effect.

[0065] like Figure 3 and Figure 4 As shown, the frame 1 is also equipped with an infrared position detector 9 and a correction device, which is controlled and coordinated with the feed motor 12. The correction device includes a correction detector 7 and a correction adjustment assembly. The frame 1 is equipped with a sliding track 19, on which a slide plate 191 is slidably mounted. The feed motor 12 is mounted on the slide plate 191. The correction adjustment assembly includes a correction cylinder 8. The correction detector 7 is electrically connected to the correction cylinder 8 and is controlled and coordinated. The slide plate 191 is equipped with a linkage block 192. The piston rod of the correction cylinder 8 is connected to the linkage block 192. The correction cylinder 8 drives the slide plate 191 to move through the linkage block 192.

[0066] During the feeding process, the infrared position detector 9 always irradiates the lowest point of the partition net or diaphragm at the feeding end. When the infrared position detector 9 detects that the degree of sagging of the partition net is low, that is, the discharge speed of the feeding motor 12 is greater than the feeding speed of the automatic feeding device, the infrared position detector 9 will feed back the signal to the feeding motor 12 to reduce the speed of the feeding motor 12. Conversely, the infrared position detector 9 will speed up the speed of the feeding motor 12. In this way, the feeding process of the partition net is more orderly, and the partition net between the cutting device and the material reel 11 will not be too loose or too tight.

[0067] The deflection correction detector 7 always detects the position of the partition net, diaphragm and the edge of the guide cloth. When the deflection correction detector 7 detects that the position of each material is offset in the width direction, the signal is fed back to the deflection correction electric cylinder 8. The deflection correction electric cylinder 8 is started, and the piston rod of the deflection correction electric cylinder 8 drives the slide 191 to slide along the sliding track 19 through the linkage block 192. When the slide 191 slides, it can drive the feed motor 12 to move outward or inward, so that the material reel 11 drives the partition net material roll 111 on it to move along the width direction to adjust the position.

[0068] The feeding method of the present invention comprises the following steps:

[0069] S1. Loading: Install the screen roll, membrane roll, and guide fabric roll on the material reel, and arrange them in order from top to bottom. Pass the front end of the screen roll into the screen feeding and cutting device, the front end of the membrane into the membrane feeding and cutting device, and the front end of the guide fabric into the guide fabric feeding and cutting device;

[0070] S2. Film feeding and cutting: The second manipulator grabs the film at the discharge end of the film feeding and cutting device, moves and pulls out the film of appropriate length, and then cuts the film roll into individual films, which fall onto the first placement table.

[0071] S3, mesh feeding and cutting: The first manipulator grabs the front end of the mesh fed from the mesh feeding and cutting device, moves and pulls out the mesh of appropriate length, and then cuts the mesh roll into single sheets;

[0072] S4. Stacking and transferring: The first manipulator moves the screen onto the single membrane sheet on the first placement table, so that the screen is stacked on the membrane sheet to form a preliminary filtration unit. The third manipulator transfers the preliminary filtration unit to the second placement table.

[0073] S5, lifting material: the lifting electric cylinder drives the guide cloth feeding and cutting device to rise relative to the platform;

[0074] S6. Feeding and cutting the guide cloth: The third robot grabs the front end of the guide cloth delivered from the guide cloth feeding and cutting device, moves and pulls out the guide cloth of appropriate length, and then cuts the guide cloth roll into single sheets;

[0075] S7, stacking the guide cloth: The third manipulator drives the guide cloth to move horizontally above the primary filtration unit, and stacks the guide cloth on the primary filtration unit to form a reverse osmosis membrane unit;

[0076] S8, avoidance: the lifting electric cylinder drives the guide cloth feeding and cutting device to descend relative to the platform to avoid the third manipulator, and the third manipulator is reset to above the first placement table.

[0077] The basic operating principle of the present invention is as follows: The second manipulator grasps the front end of the membrane and conveys and cuts it through the membrane feeding and cutting device, which is then placed on the first storage table. The screen roll is then conveyed and cut through the screen feeding and cutting device. The first manipulator stacks the cut screen on the cut membrane to form a preliminary filtration unit, which is then pressed and positioned by a rotating pressing member on the platform. At this point, the guide cloth feeding and cutting device is located below the platform, and the third manipulator moves the preliminary filtration unit from the first storage table to the second storage table. Subsequently, the guide cloth feeding and cutting device rises relative to the platform, and the guide cloth is conveyed and cut through the guide cloth feeding and cutting device. The third manipulator stacks the cut guide cloth on the preliminary filtration unit to form a reverse osmosis membrane unit. The guide cloth feeding and cutting device descends and resets, clearing the way for the third robot, which then moves horizontally above the first placement table to wait for the next preliminary filtration unit. This facilitates the feeding of the screen, membrane, and guide cloth. The membrane, screen, and guide cloth are fed sequentially in a three-in-one fashion on the same rack and transported along the conveyor channel formed between the first and second placement tables. Manual stacking of the three cut materials is eliminated, allowing the membrane, screen, and guide cloth to be automatically and neatly stacked. This creates a rational layout, a high degree of automation, and significant time and labor savings. A deviation correction device ensures the alignment accuracy of the three materials during feeding and stacking.

[0078] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
