Description

A production line for spiral wound water filter cartridges Technical Field

[0001] This invention relates to the field of spiral wound water filter cartridge manufacturing technology, specifically to a spiral wound water filter cartridge folding production line. Background Technology

[0002] Spiral-wound water filter cartridges are widely used in water treatment equipment in households, industries, and medical fields to achieve purposes such as tap water purification, sewage treatment, and the production of pure water for industrial and medical use. The current workflow of existing equipment on the market is as follows: The operator manually inputs the new membrane material number into the industrial control computer, loads the coarse mesh and membrane sheet onto the loading mechanism, presses the start button, and the membrane sheet traction mechanism pulls out the membrane sheet for cutting by the membrane sheet cutting mechanism. Then, the membrane sheet seam tape application mechanism applies tape to the membrane sheet seam. Simultaneously, the coarse mesh traction mechanism pulls out the coarse mesh for cutting by the coarse mesh cutting mechanism. The coarse mesh vertical conveying mechanism vertically inserts the coarse mesh into the membrane sheet seam, and then the membrane sheet folding and heating mechanism heats, folds, and welds the membrane sheet. Simultaneously, the membrane sheet end-sealing mechanism performs membrane sheet end-sealing. After folding, the membrane sheet and coarse mesh assembly traction mechanism pulls the assembly to the docking point with the spiral-wound unit, and this cycle repeats. However, in the existing workflow, processes such as film cutting, coarse mesh cutting, applying adhesive tape to the film seam, and end sealing all require the film or coarse mesh to be in a static state, which prolongs the entire roll film production cycle and reduces production efficiency. Summary of the Invention

[0003] This invention provides a folding production line for spiral-wound water filter cartridges, which can solve the problem that the membrane or coarse mesh must be in a static state during some process steps, thus reducing the overall production efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a folding production line for spiral-wound water filter cartridges, comprising a folding line frame, a coarse mesh roll feeding rack at the left end of the folding line frame, a membrane roll feeding and correction rack at the left end of the coarse mesh roll feeding rack, a membrane positioning platform and a membrane guide cloth docking platform sequentially installed at the right end of the folding line frame, multiple vacuum conveying devices sequentially installed from left to right on the upper side of the folding line frame, and a membrane buffer installed near the right end on the upper side of the folding line frame. The vacuum conveyor device includes a conveyor belt and a diaphragm incline conveyor belt. From left to right, the upper side of the vacuum conveyor is equipped with a diaphragm seam tape applicator, a coarse mesh diaphragm cutting device, a coarse mesh applicator for the diaphragm, and a diaphragm folding device. The diaphragm folding device is installed in the gap between the diaphragm buffer conveyor belt and the vacuum conveyor device. The lower end of the diaphragm incline conveyor belt extends to the lower end of the diaphragm buffer conveyor belt. A diaphragm folding seam heat-pressing and leveling device, which can slide obliquely along the diaphragm incline conveyor belt, is provided between the diaphragm incline conveyor belt and the diaphragm buffer conveyor belt. The top of the membrane guide fabric docking platform is equipped with a membrane side-pulling and lateral movement device. This device has laterally movable membrane side-pulling grippers. The membrane on the membrane roll feeding and correction frame and the coarse mesh on the coarse mesh roll feeding frame pass sequentially through the membrane center seam tape applicator, the coarse mesh membrane slitting device, and the coarse mesh pasting device to form a membrane-mesh assembly sheet. This assembly is then folded at the membrane folding device to form a membrane bag. The membrane bag is pulled into the membrane positioning table and the membrane guide fabric docking platform by the membrane folding and hot-pressing leveling device for storage. The negative pressure of the fan adsorbs the diaphragm onto the vacuum conveying device, allowing the diaphragm to be pulled out continuously without interruption. The coarse mesh diaphragm cutting device can dynamically cut the diaphragm and coarse mesh in sync with the production line speed. The diaphragm seam tape application device can dynamically apply tape to the diaphragm seam in sync with the production line speed. The diaphragm folding device can dynamically fold the diaphragm in sync with the production line speed. The diaphragm seam heat pressing and leveling device can dynamically level the diaphragm seam in sync with the production line speed. During the entire production line, each process operates synchronously, achieving continuous and uninterrupted output of membrane bags, greatly improving production efficiency.

[0005] Preferably, the diaphragm-attaching seam tape device and the coarse mesh-attaching diaphragm device have the same structure, both including a substrate. A linear guide rail is laterally arranged on the upper front side of the substrate. A tape gripper moving platform is slidably arranged on the linear guide rail. A tape gripper assembly is installed on the lower side of the tape gripper moving platform. The tape gripper moving platform is driven by a translation drive assembly to slide back and forth along the linear guide rail. A roller is laterally installed on the lower front side of the substrate. A tape adsorption strip is installed axially on one side of the roller. Vacuum adsorption holes are evenly distributed on the tape adsorption strip. The roller is driven to rotate by a rotation drive assembly mounted on the substrate. A tape cutting assembly is installed on the upper side of one end of the roller. Tape is installed on the substrate near the tape cutting assembly. A tape guide assembly is provided on the base plate between the tape reel and the tape cutting assembly. The tape guide assembly guides the tape on the tape reel to the position of the tape cutting assembly. The tape is grasped by the tape gripper assembly and pulled horizontally to the other end of the roller. The tape cut by the tape cutting assembly is adsorbed on the tape adsorption strip. As the roller rotates, the tape is attached to the conveyed film or coarse mesh. The tape cutting assembly includes a cutter rotation power cylinder and a tape cutter installed on one side of the cutter rotation power cylinder. When the tape cutter rotates towards the roller, it cuts the tape. The rotation of the roller is matched with the movement rhythm of the tape gripper moving platform, so that the tape can be continuously attached to the center position of the conveyed film without stopping the production line, which greatly improves the production cycle.

[0006] Preferably, the tape gripper assembly includes upper and lower tape gripper cylinders connected to the tape gripper moving platform and an outer frame mounted on the lower extension rod of the upper and lower tape gripper cylinders. A tape clamping wheel is installed at the lower end of the outer frame near the tape cutting assembly. A first gripper cylinder is installed on the outer frame, and a second gripper cylinder is installed on the lower extension rod of the first gripper cylinder. A tape gripper component is installed on the horizontal extension rod of the second gripper cylinder facing the tape clamping wheel. This ingenious design allows the tape gripper and tape clamping wheel to clamp, pull, and release the end of the tape by alternating use of the upper and lower tape gripper cylinders, the first gripper cylinder, and the second gripper cylinder.

[0007] Preferably, the coarse mesh film slitting device includes a frame, inside which a coarse mesh pulling power shaft is horizontally mounted. A coarse mesh pressing roller is mounted on the upper side of the coarse mesh pulling power shaft. A coarse mesh cutter frame is mounted on one side of the coarse mesh pulling power shaft, and at least one coarse mesh upper cutter is mounted on the coarse mesh cutter frame. A coarse mesh lower cutter is mounted at a corresponding position on the side of the coarse mesh upper cutter. A coarse mesh power conveying assembly extending to the lower part of the frame is provided on one side of the coarse mesh cutter frame. A film cutter frame and a corresponding film lower cutter are mounted on the lower part of the frame, and at least one film upper cutter is mounted on the film cutter frame. The aforementioned coarse mesh pulling power shaft, coarse mesh cutting knife holder, and film cutting knife holder are respectively driven to rotate by a coarse mesh pulling power servo motor, a coarse mesh rolling cutting power servo motor, and a film rolling cutting power servo motor at one end of the frame. Through the rolling of the coarse mesh pulling power shaft and the coarse mesh pressing roller, the coarse mesh can be continuously pulled in and passed between the coarse mesh cutting knife holder and the coarse mesh lower cutting knife. During the continuous conveying of the coarse mesh, the coarse mesh can be cut by the coarse mesh upper cutting knife and the coarse mesh lower cutting knife. At the same time, the film upper cutting knife and the film lower cutting knife can cut the horizontally conveyed film. The cut coarse mesh segments and film segments can be matched and positioned. The entire process does not require the production line to stop, ensuring production efficiency.

[0008] Preferably, a coarse mesh buffer storage assembly is installed on the side of the frame away from the coarse mesh power transmission assembly. The coarse mesh buffer storage assembly includes a first coarse mesh buffer roller and a second coarse mesh buffer roller arranged side by side at the upper end of the frame, and a third coarse mesh buffer roller installed at the lower part of the frame. The coarse mesh passes around the first coarse mesh buffer roller, the third coarse mesh buffer roller, and the second coarse mesh buffer roller in sequence. In this way, if there is a problem with the subsequent coarse mesh, the coarse mesh wound on the coarse mesh buffer assembly can be used up first, so that there will be time for the control personnel to deal with the problem.

[0009] Preferably, the film folding device includes a folding frame with a hollowed-out bottom. A revolution-rotation shaft is horizontally mounted in the middle of the folding frame. The revolution-rotation shaft is driven to rotate by a revolution-rotation power motor at one end of the folding frame. Rotation shaft brackets are mounted at both ends of the revolution-rotation shaft, arranged radially along the revolution-rotation shaft. A rotation-rotation shaft is connected between the ends of the rotation-rotation shaft brackets. A mold insert is mounted axially on the outer side of the rotation-rotation shaft. A revolution-fixed gear is coaxially mounted at one end of the revolution-rotation shaft. A self-rotation shaft is mounted at one end of the rotation-rotation shaft, which is driven by the revolution-fixed gear. The rotating gear, when the self-rotating shaft support and the revolution rotating shaft rotate, the self-rotating shaft rotates. When the self-rotating rotating shaft moves to the lower end of the folding frame, the inserting die remains in a downward position. Through the transmission cooperation between the self-rotating rotating gear and the revolution fixed gear, the self-rotating shaft and the inserting die can rotate synchronously when the revolution rotating shaft and the self-rotating shaft support rotate. The inserting die can change its orientation as the diaphragm moves, inserting the diaphragm into the joint between the two diaphragm buffer belts and the vacuum conveying device. The diaphragm buffer belts and the vacuum conveying device can then fold the diaphragm. The diaphragm can be folded during the conveying process without stopping the production line.

[0010] Preferably, the diaphragm fold seam hot pressing and leveling device includes a mechanism mounting plate for mounting on the side slide rail of the diaphragm climbing conveyor belt, and is driven to move by a translation drive component. At least one lifting power cylinder is mounted on the mechanism mounting plate. Side mounting plates are mounted on the lower sides of both ends of the mechanism mounting plate. A lower heating plate fixing frame is mounted between the lower ends of the side mounting plates. A lower heating plate is mounted on the upper side of the lower heating plate fixing frame. An extension rod for the lifting power cylinder is provided between the side mounting plates. The upper heating plate is connected to the upper heating plate fixing frame. The lower end of the upper heating plate fixing frame is equipped with an upper heating plate. The upper heating plate switches between an upper position and a lower position under the drive of the lifting power cylinder. When the upper heating plate is in the lower position, it clamps and presses the film bag together with the lower heating plate. After the upper heating plate and the lower heating plate clamp the fold seam of the film, the entire mechanism mounting plate can move with the film conveying under the drive of the translation drive component. After flattening, the upper heating plate and the lower heating plate can release the film. The film conveying does not need to be stopped throughout the entire process.

[0011] Preferably, the vacuum conveying device includes a negative pressure chamber, with side support plates installed on both the front and rear sides of the negative pressure chamber. A drive shaft and a driven shaft are respectively installed between the side support plates at both ends of the negative pressure chamber. A drive assembly is installed at one end of the drive shaft. A porous vacuum conveyor belt that passes horizontally from the upper side of the negative pressure chamber is wound between the drive shaft and the driven shaft. An air inlet structure matching the porous vacuum conveyor belt is arranged on the upper side of the negative pressure chamber. A negative pressure fan interface is also provided on the negative pressure chamber. By setting up a negative pressure chamber, a continuous negative pressure can be generated when the porous vacuum conveyor belt passes over the upper side of the negative pressure chamber, which will attract the diaphragm on the upper side of the porous vacuum conveyor belt and convey it with the movement of the porous vacuum conveyor belt, so that the conveying of the diaphragm in the entire production line will not stop, thus improving the production cycle.

[0012] Preferably, the diaphragm side-pulling gripper includes a lifting drive unit that is mounted on the diaphragm side-pulling and lateral movement device for movement. The lifting drive unit is equipped with a liftable side-pulling plate. Supporting folds are provided at both ends of the lower side of the side-pulling plate. A cylinder clamp is installed above the supporting folds. The diaphragm bag can be pulled onto the diaphragm guide cloth docking platform by the cooperation of the cylinder clamp and the supporting folds.

[0013] Preferably, a membrane anti-tilting pressure plate device is installed between the membrane positioning platform and the membrane guide cloth docking platform. The membrane anti-tilting pressure plate device includes a transverse rotating shaft installed horizontally above the membrane positioning platform. Several downwardly extending pressure plates are installed on the transverse rotating shaft along the axial direction. One end of the transverse rotating shaft is provided with a pressure plate rotation drive motor, which can ensure that the membrane bag will not tilt up when it moves.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This allows for synchronized operation of all processes within the production line, ensuring continuous and uninterrupted output of membrane bags. While retaining the original production technology, it significantly improves production cycle time, reduces equipment costs, and enhances product stability. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] This invention addresses the issue of reduced overall production efficiency in film folding production lines due to the requirement that membranes or coarse mesh remain stationary during certain processing steps. As shown in Figures 1-18, the following technical solution is provided: A film folding production line for spiral-wound water filter cartridges includes a film folding line frame 18. A coarse mesh roll feeding rack 7 is located at the left end of the film folding line frame 18, and a membrane roll feeding and correction rack 6 is installed at the left end of the coarse mesh roll feeding rack 7. A membrane positioning platform 16 and a membrane guide cloth docking platform 19 are sequentially installed at the right end of the film folding line frame 18. Multiple vacuum conveying devices 11 are sequentially installed on the upper side of the film folding line frame 18 from left to right. A membrane buffer belt is installed on the upper side of the film folding line frame 18 near the right end. 15 and 26 are membrane climbing belts. On the upper side of the vacuum conveying device 11, from left to right, are sequentially installed a membrane center seam tape device 9, a coarse mesh membrane cutting device 12, a coarse mesh pasting device 13, and a membrane folding device 14. The membrane folding device 14 is installed in the gap between the membrane buffer belt 15 and the vacuum conveying device 11. The lower end of the membrane climbing belt 26 extends to the lower end of the membrane buffer belt 15. A membrane folding seam heat-pressing device is provided between the membrane climbing belt 26 and the membrane buffer belt 15, allowing it to slide obliquely along the membrane climbing belt 26. The membrane guide fabric docking platform 19 is equipped with a membrane side-pulling and lateral movement device 17 on its top. The membrane side-pulling and lateral movement device 17 is equipped with a transversely movable membrane side-pulling gripper 24. The membrane on the membrane roll feeding and correction frame 6 and the coarse mesh on the coarse mesh roll feeding frame 7 pass through the membrane center seam tape device 9, the coarse mesh membrane cutting device 12, and the membrane attaching device 13 in sequence to form a membrane-mesh combination sheet. The sheet is then folded at the membrane folding device 14 to form a membrane bag. The membrane bag is pulled into the membrane positioning table 16 and the membrane guide fabric docking platform by the membrane folding and hot pressing leveling device 25. The membrane is stored in platform 19. The negative pressure of the fan is used to adsorb the membrane onto the vacuum conveying device 11, which can continuously pull out the membrane. The coarse mesh membrane cutting device 12 can dynamically cut the membrane and coarse mesh in sync with the line speed. The membrane seam tape applicator 9 can dynamically apply tape to the membrane seam in sync with the line speed. The membrane folding device 14 can dynamically fold the membrane in sync with the line speed. The membrane seam heat pressing and leveling device 25 can dynamically level the membrane seam in sync with the line speed. During the production process, all processes of the entire line operate synchronously to achieve continuous and uninterrupted output of membrane bags, which greatly improves production efficiency.

[0038] In this embodiment, a coarse wire mesh hoisting frame 1 can be installed above the coarse wire mesh roll feeding rack 7. A slide rail and an electric hoist can be installed on the coarse wire mesh hoisting frame 1 to facilitate hoisting the coarse wire mesh roll or film roll into place. Coarse wire mesh roll B4 and coarse wire mesh roll A3 can be installed on the top and one side of the coarse wire mesh roll feeding rack 7, respectively. Film roll 2 can be installed on the film roll feeding and correction frame 6, and the film roll 8 to be fed can be placed in advance on one side of the film roll feeding and correction frame 6.

[0039] A diaphragm CCD detection system can be installed on the coarse wire mesh feeder 7 to visually inspect the conveyed diaphragm. To facilitate the operation of the diaphragm and coarse wire mesh, a step 5 can be installed on one side of the coarse wire mesh feeder 7.

[0040] The membrane real-time position detection device A22 and the membrane real-time position detection device B23 can be installed at two positions on the upper side of the vacuum conveying device 11, respectively, so as to track the position of the membrane in real time.

[0041] In this embodiment, as shown in Figures 5-8, the diaphragm-attaching seam tape device 9 and the diaphragm-attaching coarse mesh device 13 have the same structure, both including a substrate 91. A linear guide rail 93 is laterally arranged on the upper front side of the substrate 91. A tape gripper moving platform 94 is slidably arranged on the linear guide rail 93. A tape gripper assembly 97 is installed on the lower side of the tape gripper moving platform 94. The tape gripper moving platform 94 is driven by a translation drive assembly 912 to slide back and forth along the linear guide rail 93. A roller 99 is laterally installed on the lower front side of the substrate 91. A tape adsorption strip 98 is installed axially on one side of the roller 99. Vacuum adsorption holes are evenly distributed on the tape adsorption strip 98. The roller 99 is driven to rotate by a rotation drive assembly 910 mounted on the substrate 91. A tape cutting assembly 92 is installed on the upper side of one end of the roller 99. A tape cutting assembly 92 is installed on the substrate 91 near the tape cutting assembly 92. A tape reel 95 is installed at position 2. A tape guide assembly is provided on the base plate 91 between the tape reel 95 and the tape cutting assembly 92. The tape guide assembly guides the tape on the tape reel 95 to the position of the tape cutting assembly 92. The tape is grasped by the tape gripper assembly 97 and pulled flat to the other end of the roller 99. The tape cut by the tape cutting assembly 92 is adsorbed on the tape adsorption strip 8. As the roller 99 rotates, the tape is attached to the conveyed film or coarse mesh. The tape cutting assembly 92 includes a cutter rotation power cylinder 913 and a tape cutter 914 installed on one side of the cutter rotation power cylinder 913. When the tape cutter 914 rotates towards the roller 99, it cuts the tape. The rotation of the roller 99 is matched with the movement rhythm of the tape gripper moving platform 94, so that the tape can be continuously attached to the center position of the conveyed film without stopping the production line, which greatly improves the production cycle.

[0042] Specifically, the substrate 91 has a vertical plate structure and can be installed on the production line. The film and the coarse screen both pass through the bottom of the roller 99, so the rotation of the roller 99 is matched with the conveying speed of the film and the coarse screen. When the roller 99 drives the tape adsorption strip 98 to rotate to the bottom, it corresponds to the center line position of the film, and the tape can be applied accordingly.

[0043] A side plate can be installed at one end of the base plate 91. Both the translation drive assembly 912 and the rotation drive assembly 910 can be installed on the side plate. At the same time, one end of the roller 99 can also be fixed by the side plate, while the other end of the roller 99 is fixed by a fixing bracket 96 installed on the base plate 91. A pad can be installed on the upper end of the fixing bracket 96. The upper end of the pad is provided with a guide groove that matches the width of the tape. After the tape passes through the tape guide assembly, the tape passes horizontally through the guide groove. Meanwhile, a tape fixing and pressing cylinder 911 is installed on the side of the tape cutting assembly 92 near the tape reel 95 to press down the end of the tape cut by the tape cutting assembly 92. In this way, the tape gripper assembly 97 can accurately grasp the end of the tape each time, ensuring the continuous operation of the production line. The tape fixing and pressing cylinder 911 can be installed on the upper side of the pad. A pressure block is installed on the extension rod of the tape fixing and pressing cylinder 911 to press the end of the tape onto the pad and keep the tape from moving.

[0044] As shown in Figures 5 and 8, the end of the roller 99 is connected to a vacuum rotary air connector 922. The vacuum adsorption holes on the tape adsorption strip 98 are connected to the vacuum rotary air connector 922. The vacuum rotary air connector 922 is connected to a vacuum device, which can continuously evacuate air from the vacuum adsorption holes on the tape adsorption strip 98 to form a negative pressure, so that the tape is adsorbed on the tape adsorption strip 98 and will not fall off until the tape is attached to the diaphragm. The rotation of the roller 99 will not affect the normal use of the vacuum rotary air connector 922. A connecting pipe can be set inside the roller 99 to connect the vacuum adsorption holes on the tape adsorption strip 98 to the vacuum rotary air connector 922.

[0045] In this embodiment, as shown in Figure 7, the tape gripper assembly 97 includes a tape gripper upper and lower cylinder 971 connected to the tape gripper moving platform 94 and an outer frame 973 mounted on the lower extension rod of the tape gripper upper and lower cylinder 971. A tape clamping wheel 976 is mounted on the lower end of the outer frame 973 near the tape cutting assembly 92. A first gripper cylinder 972 is mounted on the outer frame 973. A second gripper cylinder 974 is mounted on the lower extension rod of the first gripper cylinder 972. A tape gripper component 975 is mounted on the horizontal extension rod of the second gripper cylinder 974 facing the tape clamping wheel 976. The design is ingenious. By alternating the use of the tape gripper upper and lower cylinder 971, the first gripper cylinder 972, and the second gripper cylinder 974, the tape gripper component 975 and the tape clamping wheel 976 can clamp, pull, and release the end of the tape.

[0046] In this embodiment, as shown in FIG8, the tape guiding assembly includes a plurality of tape guiding wheels 915 installed between one end of the roller 99 and the tape reel 95, so that the tape enters at a horizontal angle between the tape cutting assembly 92 and the roller 99. The tape guiding wheels 915 can be flexibly set and the tension can be adjusted. Specifically, the tape reel 95 can be installed on the upper part of one end of the substrate 91. The tape coming out of the tape reel 95 can be guided downward first, then upward, and then enter the tape cutting assembly 2 and the roller 99 in a horizontal state. The tape guiding wheels 915 can be installed at the position where the tape needs to be turned, and the number can be adjusted as needed.

[0047] In this embodiment, the tape guiding assembly further includes a tape pre-folding assembly. The tape pre-folding assembly includes a swing member 917 rotatably mounted on a substrate 91. A folding pressure roller 918 is mounted on the lower end of the swing member 917. A folding roller 919 with a V-shaped groove around its circumference is mounted on one side of the folding pressure roller 918. An elastic member 916 is mounted between the upper end of the swing member 917 and the substrate 91. The elastic member 916 causes the folding pressure roller 918 to press against the folding roller 919, forming a folding crease on the surface of the tape that passes over the folding roller 919. The cooperation of the folding pressure roller 918 and the folding roller 919 in forming a folding crease on the surface of the tape facilitates the folding of the film in subsequent processes, solving the problem that the tape is not easy to fold in subsequent folding processes.

[0048] In this embodiment, a tape detection sensor 921 is also installed at the position of the tape guide assembly. Once the tape being transported by the tape guide assembly is found to be broken or used up, the production line can be stopped immediately.

[0049] As a specific embodiment of the translation drive assembly 912, as shown in Figures 5 and 6, the translation drive assembly 912 includes a lead screw 9127 parallel to the linear guide rail 93 and a lead screw slider 9126 mounted on the lead screw 9127. The lead screw slider 9126 is connected to the conveyor belt gripper moving platform 94. One end of the lead screw 9127 is connected to a first driven wheel 9124. A first driving wheel 9122 is provided on one side of the first driven wheel 9124. The first driven wheel 9124 and the first driving wheel 9122 are connected by a first transmission belt 9123. The first driving wheel 9122 is driven by a first power motor 9121. A first tensioning wheel 9125 that contacts the first transmission belt 9123 is also installed on one side of the first driven wheel 9124 and the first driving wheel 9122. The lead screw drive enables the conveyor belt gripper moving platform 94 to move back and forth accurately.

[0050] As a specific embodiment of the rotary drive assembly 910, as shown in Figures 5 and 6, the rotary drive assembly 910 includes a second driven wheel 9103 installed at one end of the shaft of the roller 99 and a second driving wheel 9104 installed on one side of the second driven wheel 9103. The second driven wheel 9103 and the second driving wheel 9104 are connected by a second transmission belt 9105. The second driving wheel 9104 is driven by a second power motor 9101. A second tensioning wheel 9102 that contacts the second transmission belt 9105 is also installed on one side of the second driven wheel 9103 and the second driving wheel 9104.

[0051] As shown in this embodiment, the overall workflow of the diaphragm-seam tape applicator 9 and the coarse mesh applicator 13 is as follows:

[0052] Preparation: First, manually install the tape reel 95 onto the chuck. Then, manually pull the tape out from the tape reel 95, around the tape guide assembly and the tape pre-folding assembly. Finally, fix the tape end to the tape fixing and pressing cylinder 911. Manually press down the tape cutter 914 to remove the excess tape end, and then start the equipment.

[0053] Equipment workflow:

[0054] The equipment adjusts preset parameters and starts the translation drive assembly 912 and the rotary drive assembly 910. The rotary drive assembly 910 rotates the tape suction strip 98 to a vertically upward position. Simultaneously, the translation drive assembly 912 clamps the tape head with the tape gripper assembly 97, and the tape gripper's up-and-down cylinder 971 retracts. The translation drive assembly 912 moves the tape gripper assembly 97 to the tape release position and releases the tape head. The vacuum rotary air connector 922 connects to the vacuum, and the cutter rotary power cylinder 913 starts, driving the tape cutter 914 to cut the tape. At the same time, the tape suction strip 98 absorbs the cut tape. At this time, the diaphragm passes underneath, and the equipment records the diaphragm position. After reaching the preset point, the rotary drive assembly 910 rotates the tape suction strip 98 synchronously, applying the tape to the center of the diaphragm, and the cycle repeats. Similarly, the principle of pasting the coarse mesh to the diaphragm device 13 is the same as that of the diaphragm seam tape device 9. The difference is that the coarse mesh pasting device 13 uses tape to stick the coarse mesh and the diaphragm together.

[0055] In this embodiment, as shown in Figures 3-4, the coarse mesh film slitting device 12 includes a frame 125. A coarse mesh pulling power shaft 1213 is horizontally mounted inside the frame 125. A coarse mesh pressing roller 1214 is mounted on the upper side of the coarse mesh pulling power shaft 1213. A coarse mesh cutter holder 1210 is mounted on one side of the coarse mesh pulling power shaft 1213. At least one coarse mesh upper cutting blade 1220 is mounted on the coarse mesh cutter holder 1210. A coarse mesh lower cutting blade 1221 is mounted at a corresponding position on the side of the coarse mesh upper cutting blade 1220. A coarse mesh power conveying assembly 128 extending to the lower part of the frame 125 is provided on one side of the coarse mesh cutter holder 1210. A film cutter holder 1217 and a corresponding film lower cutting blade 1219 are mounted on the lower part of the frame 125. A film cutter holder 1217 is mounted on the film cutter holder 1217. At least one upper diaphragm cutter 1218 is provided. The coarse mesh pulling power shaft 1213, coarse mesh cutter holder 1210, and diaphragm cutter holder 1217 are respectively driven to rotate by the coarse mesh pulling power servo motor 124, coarse mesh rolling power servo motor 123, and diaphragm rolling power servo motor 122 at one end of the frame 125. The coarse mesh can be continuously pulled in through the rolling of the coarse mesh pulling power shaft 1213 and the coarse mesh pressing roller 1214, passing between the coarse mesh cutter holder 1210 and the lower coarse mesh cutter 1221. During the continuous conveying of the coarse mesh, the upper coarse mesh cutter 1220 and the lower coarse mesh cutter 1221 can cut the coarse mesh. At the same time, the upper diaphragm cutter 1218 and the lower diaphragm cutter 1219 can cut the horizontally conveyed diaphragm. The cut coarse mesh segments and diaphragm segments can be matched and positioned. The entire process does not require the production line to stop, ensuring production efficiency.

[0056] In this embodiment, the membrane can pass horizontally between the upper membrane cutter 1218 and the lower membrane cutter 1219, and the cut membrane segments can also be conveyed forward by the vacuum conveying device 11.

[0057] The coarse mesh cutter 1220 and the coarse mesh cutter holder 1210 are tangentially connected. Two coarse mesh cutters 1220 can be symmetrically arranged on the outside of the coarse mesh cutter holder 1210. Similarly, the membrane upper cutter 1218 and the membrane cutter holder 1217 are also tangentially connected. The coarse mesh lower cutter 1221 and the membrane lower cutter 1219 are both obliquely arranged. When the coarse mesh cutter 1220 moves to the position corresponding to the coarse mesh lower cutter 1221, the coarse mesh cutter 1220 and the coarse mesh lower cutter 1221 form a V-shaped angle. When the membrane upper cutter 1218 moves to the position corresponding to the membrane lower cutter 1219, the membrane upper cutter 1218 and the membrane lower cutter 1219 form a V-shaped angle. This angle can ensure that the coarse mesh and the membrane are cut off quickly.

[0058] In this embodiment, the frame 125 includes wall panels on both sides and multiple fixing rods connecting the wall panels, forming a fully hollow structure in the conveying direction, which facilitates the installation of various axial components inside, while power components such as motors are installed on one of the wall panels.

[0059] As shown in Figures 3 and 4, the coarse mesh power conveying assembly 128 is arranged at an angle. The coarse mesh power conveying assembly 128 includes a coarse mesh conveyor belt drive shaft 1212 and a coarse mesh conveyor belt driven shaft 1211. A conveyor belt 1216 is installed side by side between the coarse mesh conveyor belt drive shaft 1212 and the coarse mesh conveyor belt driven shaft 1211. The coarse mesh conveyor belt drive shaft 1212 is driven to rotate by a coarse mesh conveyor belt power servo motor 121 at one end of the frame 125. The precise rotation of the coarse mesh conveyor belt drive shaft 1212 can drive the conveyor belt 1216 to move at a uniform speed, conveying the cut coarse mesh segments forward. The coarse mesh conveyor belt drive shaft 1212 can be set at the upper end or the lower end. Among them, a guide rod 1223 extending obliquely downward is provided between adjacent conveyor belts 1216. The guide rod 1223 can guide the cut coarse mesh segment and prevent it from deviating. The end of the guide rod 1223 is provided with a horizontal part, which can place the coarse mesh segment smoothly onto the diaphragm.

[0060] The two ends of the pressing roller 1214 are connected to the lifting cylinders 129 on the frame 125, which can control the height of the pressing roller 1214, thereby automatically adjusting the pressure of the pressing roller 1214 and the pulling roller 1213 on the coarse mesh. During conveying, the lifting cylinders 129 drive the pressing roller 1214 to press down. When it is necessary to stop for maintenance, the pressing roller 1214 can be lifted. The conveying line speed of the coarse mesh power conveying assembly 128 is greater than the conveying line speed of the pulling roller 1213. This creates a speed difference between the cut coarse mesh segments and the uncut coarse mesh, which can separate the cut coarse mesh segments. A coarse mesh transition shaft 1215 is installed on the other side of the pulling roller 1213. The coarse mesh passing around the coarse mesh transition shaft 1215 can increase the conveying tension.

[0061] Preferably, a coarse mesh buffer storage assembly 10 is installed on the side of the frame 125 away from the coarse mesh power transmission assembly 128. The coarse mesh buffer storage assembly 10 includes a first coarse mesh buffer roller 106 and a second coarse mesh buffer roller 107 arranged side by side on the upper part of the frame 125, and a third coarse mesh buffer roller 1022 installed on the lower part of the frame 125. The coarse mesh passes around the first coarse mesh buffer roller 106, the third coarse mesh buffer roller 1022 and the second coarse mesh buffer roller 107 in sequence. In this way, if there is a problem with the subsequent coarse mesh, the coarse mesh wound on the coarse mesh buffer assembly 10 can be used up first, so that there will be time for the control personnel to deal with the problem.

[0062] The specific implementation principle of the coarse mesh film cutting device 12 in this embodiment is as follows:

[0063] When the equipment is started, the coarse mesh pulling servo motor 124 drives the coarse mesh pulling power shaft 1213 to rotate, stretching the coarse mesh 1224 forward to a preset length. The coarse mesh rolling cutting servo motor 123 starts, driving the coarse mesh cutter holder 1210 and the coarse mesh upper cutting blade 1220 to rotate, cutting the coarse mesh with the blade of the coarse mesh lower cutting blade 1221. The cut coarse mesh segments fall onto the coarse mesh power conveyor assembly 128. The coarse mesh conveyor belt power servo motor 1 starts quickly, driving the coarse mesh conveyor belt drive shaft 1212 to rotate. The conveyor belt 1216 carries the coarse mesh segments previously transported. The linear speed of the coarse mesh conveyor belt drive shaft 1212 is greater than the linear speed of the coarse mesh pulling power shaft 1213. This creates a speed difference between the cut coarse mesh and the uncut coarse mesh, separating the cut coarse mesh.

[0064] Simultaneously, the main line adsorbs the membrane and moves forward to a preset length. The membrane rolling servo motor 122 starts, driving the membrane cutter holder 1216 and the upper membrane cutter 1217 to rotate, cutting the membrane by tangencing with the lower membrane cutter 1219. The main line then drives the cut membrane 25 forward. At this point, the end of the cut coarse mesh segment moves to the center seam of the cut membrane segment. This process is controlled by a closed-loop program, allowing the subsequent tape application device to fix the coarse mesh at the center seam of the membrane. The main line continues forward, transporting the membrane assembly to the next process. Therefore, this device can perform cutting during the movement of the membrane and coarse mesh, significantly improving production cycle time.

[0065] In this embodiment, as shown in Figures 9-11, the film folding device 14 includes a folding frame 141 with a hollowed-out bottom. A revolution-rotation shaft 143 is horizontally mounted in the middle of the folding frame 141. The revolution-rotation shaft 143 is driven to rotate by a revolution-rotation power motor 142 at one end of the folding frame 141. Rotation shaft brackets 146 are installed at both ends of the revolution-rotation shaft 143, arranged radially along the revolution-rotation shaft 143. A rotation-rotation shaft 144 is connected between the ends of the rotation-rotation shaft brackets 146. A mold insert 145 is axially mounted on the outer side of the rotation-rotation shaft 144. A revolution-fixed gear 1410 is coaxially arranged at one end of the revolution-rotation shaft 143, and a device is mounted at one end of the rotation-rotation shaft 144 that is connected to the revolution-fixed gear 1410. The rotating gear 1413 with zero transmission engagement allows the rotating shaft 144 to rotate when the rotating shaft support 146 and the revolving rotating shaft 143 rotate. When the rotating shaft 144 moves to the lower end of the folding frame 141, the inserting die 145 remains in a downward position. Through the transmission engagement between the rotating gear 1413 and the revolving fixed gear 1410, the rotating shaft 144 and the inserting die 145 can rotate synchronously when the revolving rotating shaft 143 and the rotating shaft support 146 rotate. The inserting die 145 can change its orientation as the diaphragm moves, inserting the diaphragm into the joint between the two diaphragm buffer belts 15 and the vacuum conveying device 11. The diaphragm buffer belts 15 and the vacuum conveying device 11 can then fold the diaphragm. The diaphragm can be folded during the conveying process without stopping the production line.

[0066] Specifically, the function of the die inserter 145 is to allow the diaphragm to be folded in half at the center seam. The conveyor belt on the diaphragm conveying platform can act on the diaphragm from both sides to fold it in half.

[0067] The revolution rotation motor 142 can be a servo motor, which can control the speed precisely. The revolution fixed gear 1410 is fixedly installed on the folding frame 141. The diameter of the revolution fixed gear 1410 is larger than that of the rotational gear 1413. Therefore, when the rotational shaft support 146 rotates around the revolution rotational shaft 143, the rotational shaft 144 can rotate many times. In this embodiment, the ratio of the angular velocity between the revolution fixed gear 1410 and the rotational shaft 144 can be set to 1:5.

[0068] As shown in Figure 11, the insertion blade 145 and the rotation axis 144 are installed along the tangential direction, so that the insertion blade 145 has better directionality as the rotation axis 144 rotates. When the rotation axis support 146 rotates a relatively small angle, the rotation axis 144 can rotate a relatively large angle, so that the insertion blade 145 can point to the center seam of the membrane for every angle the rotation axis 144 rotates.

[0069] In this embodiment, as shown in FIG10, the side of the rotation shaft bracket 146 is equipped with an adjusting gear 1412 that meshes with both the fixed orbital gear 1410 and the rotating gear 1413. By adjusting the gear 1412, the ratio of the angular velocity between the rotating gear 1413 and the fixed orbital gear 1410 can be precisely controlled. Different adjusting gears 1412 can be replaced if different angular velocity ratios are required. The position and diameter of the adjusting gear 1412 can be adjusted.

[0070] A motor mounting base 149 is installed at one end of the folding frame 141. The revolution-rotation power motor 142 is installed at the end of the motor mounting base 149. The main shaft of the motor mounting base 149 is connected to the revolution-rotation shaft 143 through a coupling 1411 inside the motor mounting base 149. The motor mounting base 149 provides sufficient installation space for the coupling 1411. As a connection structure between the revolution-rotation shaft 143 and the spin-rotation shaft bracket 146, the revolution-rotation shaft 143 can be connected to one end of the spin-rotation shaft bracket 146. In this case, the other end of the spin-rotation shaft bracket 146 can be used to connect the spin-rotation shaft 144. When the revolution-rotation shaft 143 rotates, the spin-rotation shaft 144 can rotate around the revolution-rotation shaft 143. As another connection structure between the revolution-rotation shaft 143 and the rotation shaft support 146, the revolution-rotation shaft 143 is connected to the middle of the rotation shaft support 146, one end of the rotation shaft support 146 is connected to the other end through the rotation shaft 144, and the other end is connected to the other end through the support connecting column 1415, so that the rotation of the rotation shaft support 146 and the rotation shaft 144 is more stable.

[0071] As a specific connection method of the folding frame 141, as shown in Figure 9, the folding frame 141 includes side plates 1416 at both ends and multiple connecting rods 1417 for connecting the two side plates 1416. The structure is simple and easy to install on the production line. The film can pass horizontally through its bottom. The revolution fixed gear 1410 is fixed on one of the side plates 1416.

[0072] One end of the revolution rotation shaft 143 is equipped with a sensor plate 148 extending radially to one side. The folding frame 141 is equipped with a position sensing switch 147 corresponding to the sensor plate 148. The sensor plate 148 rotates together with the revolution rotation shaft 143. Each time it passes the position sensing switch 147, it can be counted once. In this way, the number of revolutions of the revolution rotation shaft 143 can be counted, and the number of folds can also be counted.

[0073] At least one negative ion generator 1418 can also be installed at the bottom of the folding frame 141 to purify the air within the device range and improve the quality of the membrane.

[0074] In this embodiment, as shown in Figures 12-14, the diaphragm fold seam hot pressing and leveling device 25 includes a mechanism mounting plate 251, which is installed on the side slide rail of the diaphragm climbing belt 26 and moved by a translation drive component. At least one lifting power cylinder 254 is mounted on the mechanism mounting plate 251. Side mounting support plates 255 are mounted on the lower sides of both ends of the mechanism mounting plate 251. A lower heating plate fixing frame 2511 is installed between the lower ends of the side mounting support plates 255. A lower heating plate 259 is mounted on the upper side of the lower heating plate fixing frame 2511. A connection is provided between the side mounting support plates 255 and the lifting power cylinder 254. The upper heating plate fixing frame 2515 is connected to the extension rod of 54. The lower end of the upper heating plate fixing frame 2515 is equipped with an upper heating plate 258. The upper heating plate 258 switches between the upper and lower positions under the drive of the lifting power cylinder 254. When the upper heating plate 258 is in the lower position, it clamps and presses the film bag together with the lower heating plate 259. After the upper heating plate 258 and the lower heating plate 259 clamp the fold seam of the film, the entire mechanism mounting plate 251 can move with the film conveying under the drive of the translation drive component. After flattening, the upper heating plate 258 and the lower heating plate 259 can release the film. The film conveying does not need to be stopped throughout the entire process.

[0075] Specifically, the diaphragm folding hot pressing and leveling device 25 is elongated in shape, with a simple structure and a light weight of only 12KG. Therefore, it can be easily installed on the side slide rail of the production line and can slide along the side slide rail. The temperature of the upper hot plate 258 and the lower hot plate 259 can be controlled at around 90℃ when hot pressing and leveling the diaphragm folds. Two lifting power cylinders 254 are installed at both ends of the mechanism mounting plate 251, and the synchronous movement of the two lifting power cylinders 254 can achieve stable lifting and lowering of the upper hot plate fixing frame 2515.

[0076] As shown in Figure 14, when the diaphragm folding hot pressing and leveling device 25 is in use, when the main line at the front end transports the diaphragm to the center position of the upper heating plate 258 and the lower heating plate 259, the upper and lower power cylinders 254 extend and press the upper heating plate 258 down onto the lower heating plate, holding for 3 seconds. During this process, the entire device moves synchronously along the diaphragm's movement trajectory. After 3 seconds, the upper and lower power cylinders 254 retract, releasing the diaphragm. The diaphragm folds are then hot-pressed flat, and the entire device continues to accelerate forward a distance of 10 cm, detaching from the diaphragm. The diaphragm falls back to the main line and continues to be transported forward. The device returns to its initial position, waiting for the next cycle. Therefore, the diaphragm does not need to be stopped during the entire process, nor does the conveying speed need to be changed.

[0077] A front mounting plate 256 is installed on one side of the mechanism mounting plate 251. A heating plate 2517 is installed at the lower end of the front mounting plate 256. When the upper heating plate 258 is in the upper position, it is in contact with the heating plate 2517. The heating plate 2517 can heat the upper heating plate 258. In this way, there is no need to set a heating component on the upper heating plate 258, which makes the up and down lifting of the upper heating plate 258 more flexible. That is to say, there is no need to set a heating component on the upper heating plate 258, and there is no need to consider the installation problem of the heating component dynamically lifting up and down with the upper heating plate 258.

[0078] As shown in Figure 14, a first heat insulation plate 2514 is provided between the upper heating plate 258 and the upper heating plate fixing frame 2515, a second heat insulation plate 2510 is provided between the lower heating plate 259 and the lower heating plate fixing frame 2511, and a third heat insulation plate 257 is installed between the front mounting support plate 256 and the heating plate 2517. By setting multiple heat insulation plates, the heat on the upper heating plate 258, the lower heating plate 259 and the heating plate 2517 will not be transferred to the entire production line. This not only makes the temperature of the upper heating plate 258 and the lower heating plate 259 more accurate, but also makes it safer to use.

[0079] To facilitate heating control of the heating plate 2517 and the lower heating plate 259, an upper heating rod 2512 is installed on the heating plate 2517 and a lower heating rod 2513 is installed on the lower heating plate 259. By installing the upper heating rod 2512 and the lower heating rod 2513 and connecting an external temperature controller, the temperature of the heating plate 2517 and the lower heating plate 259 can be precisely controlled.

[0080] At least two linear bearings 252 are installed on the mounting plate 251 of the mechanism. Vertical moving shafts 253 are vertically arranged through the linear bearings 252. The lower end of the vertical moving shafts 253 is connected to the upper heating plate fixing frame 2515. The cooperation between the vertical moving shafts 253 and the linear bearings 252 can make the vertical movement of the upper heating plate fixing frame 2515 more stable and prevent deflection.

[0081] In this embodiment, as shown in Figures 3-4, the lower end face of the upper heating plate 258 and the upper end face of the lower heating plate 259 are both provided with guide slopes 2516 facing the direction of membrane movement, which facilitates the membrane to be conveyed between the upper heating plate 258 and the lower heating plate 259.

[0082] In this embodiment, as shown in Figures 15-16, the vacuum conveying device 11 includes a negative pressure chamber 119. Side support plates 113 are installed on both the front and rear sides of the negative pressure chamber 119. A driving shaft 1113 and a driven shaft 1112 are respectively installed between the side support plates 113 at both ends of the negative pressure chamber 119. A drive assembly is installed at one end of the driving shaft 1113. A porous vacuum conveyor belt, passing horizontally from the upper side of the negative pressure chamber 119, is wound between the driving shaft 1113 and the driven shaft 1112. 111. An air inlet structure matching the porous vacuum conveyor belt 111 is arranged on the upper side of the negative pressure chamber 119. The negative pressure chamber 119 is also provided with a negative pressure fan interface 118. By setting the negative pressure chamber 119, a continuous negative pressure can be generated when the porous vacuum conveyor belt 111 passes over the upper side of the negative pressure chamber 119, which will suck up the diaphragm on the upper side of the porous vacuum conveyor belt 111 and convey it with the movement of the porous vacuum conveyor belt 111, so that the conveying of the diaphragm in the entire production line will not stop, and the production cycle will be improved.

[0083] The negative pressure chamber 119 is configured as a flat chamber, and the air inlet structure at the upper end can be configured as a mesh structure, which can cover the entire porous vacuum conveyor belt 111. The porous vacuum conveyor belt 111 has evenly distributed pores. After the negative pressure chamber 119 is connected to the fan through the negative pressure fan interface 118, it can continuously draw air from the upper side of the air inlet structure into the negative pressure chamber 119. The air then generates negative pressure suction through the evenly distributed pores on the porous vacuum conveyor belt 111, firmly adhering the diaphragm to the porous vacuum conveyor belt 111. The active rotating shaft 1113, driven by the drive component, can realize the cyclic movement of the porous vacuum conveyor belt 111.

[0084] The negative pressure cavity 119 is equipped with multiple cavity reinforcement members 1110 on its side wall, so that the overall strength of the negative pressure cavity 119 meets the needs of production line installation and diaphragm conveying. The cavity reinforcement members 1110 can adopt a plate-like structure to reinforce the side wall of the negative pressure cavity 119.

[0085] A guide shaft 1114 is installed between the lower parts of the side support plates 113. The porous vacuum conveyor belt 111 passes around the outside of the guide shaft 1114, ensuring sufficient tension during the cyclic movement of the porous vacuum conveyor belt 111 to meet the requirements of efficient diaphragm conveying. Simultaneously, a horizontally adjustable tension adjusting plate 112 is installed at one end of the side support plate 113, with the driven shaft 1112 installed between the two horizontal tension adjusting plates 112. A vertically adjustable tension adjusting plate 117 is installed at the lower end of the side support plate 113, with the guide shaft 1114 installed between the two vertical tension adjusting plates 117. The tension of the porous vacuum conveyor belt 111 during cyclic movement can be adjusted by adjusting the positions of the horizontal tension adjusting plates 112 and the vertical tension adjusting plates 117. The positions of the horizontal tension adjusting plates 112 and the vertical tension adjusting plates 117 can be adjusted using screws and sliding grooves.

[0086] In this embodiment, at least one anti-deviation rib 1111 is provided on the inner side of the porous vacuum conveyor belt 111. The anti-deviation rib 1111 is embedded in the corresponding limiting grooves on the driving shaft 1113, the driven shaft 1112 and the guide shaft 1114, which can effectively prevent the porous vacuum conveyor belt 111 from deviating during the transmission process. The anti-deviation rib 1111 is set along the length direction of the porous vacuum conveyor belt 111.

[0087] As shown in Figure 15, the drive assembly includes a transmission wheel 116 mounted on one end of the drive shaft 1113 and a motor 114 mounted on the side support plate 113. A transmission belt connects the main shaft of the motor 114 to the transmission wheel 116. The motor 114 is mounted on the side support plate 113 via a motor mounting base 115. A reduction gearbox can be mounted on the output end of the motor 114. The reduction gearbox is mounted on the motor mounting base 115, and a transmission wheel is also mounted on the output shaft of the reduction gearbox. The reduction wheel is connected to the transmission wheel 116 on the drive shaft 1113 via a transmission belt to achieve belt drive.

[0088] The side support plate 113 is provided with a first mounting plate 1115 extending to one side at one end near the active rotating shaft 1113. A connecting plate 1117 is installed on the side of the first mounting plate 1115.

The second mounting plate 1116, the first mounting plate 1115 and the connecting plate 1117 facilitate the installation of the entire film conveying device onto the production line, and also facilitate the sequential connection of multiple film conveying devices to achieve continuous film conveying. The lower part of the second mounting plate 1116 and the first mounting plate 1115 is provided with mounting slots, which can be installed onto the production line with fasteners. At the same time, the connecting plate 1117 can connect adjacent film vacuum conveying devices together, which is convenient for installation.

[0089] In this embodiment, as shown in Figures 17-18, the membrane side-pulling gripper 24 includes a lifting drive unit 242 that moves on the membrane side-pulling lateral movement device 17. The lifting drive unit 242 is equipped with a liftable side-pulling plate 241. Supporting folds 243 are provided at both ends of the lower side of the side-pulling plate 241. A cylinder clamp 244 is installed above the supporting folds 243. The membrane bag can be pulled onto the membrane guide cloth docking platform 19 by the cooperation of the cylinder clamp 244 and the supporting folds 243. The cylinder clamp 244 and the supporting folds 243 clamp the membrane bag. Then, the membrane side-pulling lateral movement device 17 drives the membrane side-pulling gripper 24 to move back and forth, repeatedly stacking the membrane bag on the membrane guide cloth docking platform 19.

[0090] In this embodiment, as shown in FIG17, a membrane anti-warping pressure plate device 20 is installed between the membrane positioning platform 16 and the membrane guide cloth docking platform 19. The membrane anti-warping pressure plate device 20 includes a transverse rotating shaft 201 installed horizontally above the membrane positioning platform 16. Several downwardly extending pressure plates 203 are installed on the transverse rotating shaft 201 along the axial direction. One end of the transverse rotating shaft 201 is provided with a pressure plate rotation drive motor 202, which can ensure that the membrane bag will not warp when it moves.

[0091] As a method of operation for the entire production line:

[0092] Preparatory work for equipment operation:

[0093] 1: Manually use the coarse mesh hoisting scaffold 1 to hang up and transport the coarse mesh roll and the film roll to the designated position, as shown in the figure above, for film roll 2, coarse mesh roll A3, and coarse mesh roll B4, and fix the rolls.

[0094] 2: Coarse wire mesh roll A3 and coarse wire mesh roll B4 are used interchangeably in actual production.

[0095] 3: Manually pull the membrane along the membrane insertion path and adsorb it onto the vacuum conveying device 11. Note that the length of the membrane should exceed the coarse mesh membrane cutting device 12. The vacuum conveying device 11 starts the negative pressure to adsorb the membrane onto the line.

[0096] 4: Manually press the film cutting manual button, and the coarse mesh film cutting device 12 will rotate one revolution to cut off the excess end of the film. Manually remove the cut waste film end material from the equipment and put it into the designated waste disposal area.

[0097] 5: Manually pull out the coarse mesh along the mesh threading path, making sure the length of the coarse mesh exceeds the coarse mesh film cutting device 12, and clamp the coarse mesh onto the coarse mesh film cutting device 12.

[0098] 6: Manually press the manual button for coarse mesh cutting to cut off the excess ends of the coarse mesh. Manually remove the cut waste coarse mesh ends from the equipment and place them in the designated waste disposal area.

[0099] Automated workflow:

[0100] 1. Manually input the new film material number parameters into the industrial control computer and start the equipment.

[0101] 2: The vacuum conveyor 11 adsorbs the diaphragm and moves it forward. The diaphragm roll feeding and correction frame 6 activates the correction function to prevent the diaphragm from running off the conveyor belt during movement. The diaphragm center seam tape device 9 applies the tape to the diaphragm at the appropriate position (center of the single diaphragm). When the diaphragm reaches the set parameter position, the coarse mesh diaphragm cutting device 12 operates synchronously to cut a section of the diaphragm into a single diaphragm. The single diaphragm remains adsorbed on the vacuum conveyor 11 and continues to move forward.

[0102] 3: At the same time, the coarse mesh film cutting device 12 is started, pulling the coarse mesh to the parameter set length, cutting the coarse mesh to form a single coarse mesh.

[0103] 4: When the seam of the single diaphragm moves to the end of the single coarse mesh, the coarse mesh is attached to the diaphragm device 13 and rotated to fix the coarse mesh to the seam of the single diaphragm, forming a diaphragm-mesh composite sheet.

[0104] 5: The membrane mesh assembly sheet remains adsorbed on the vacuum conveying device 11 and continues to move forward.

[0105] 6: When the seam of the membrane mesh assembly material moves to the center of the membrane folding device 14, the membrane folding device 14 rotates and squeezes the seam of the membrane mesh assembly material downward to form a fold. The folded membrane wraps the coarse mesh to form a membrane bag. At this time, the membrane is U-shaped with the coarse mesh in the middle.

[0106] 7: The film bag continues to move downwards from directly below the film folding device 14, and reaches the film fold seam hot pressing and leveling device 25. The film fold seam hot pressing and leveling device 25 is activated, clamps the end of the film bag, and moves forward synchronously.

[0107] 8: After the membrane folding device 14 moves for a few seconds (3 seconds), it clamps and releases the membrane. The membrane fold seam is then heat-pressed flat. The membrane folding device 14 continues to accelerate forward for 10 cm, detaching from the membrane. The membrane bag falls back onto the membrane climbing belt 26 and continues to be conveyed forward. The membrane folding device 14 returns to its initial position.

[0108] 9: After the membrane bag is transported to the membrane positioning table 16, the membrane is positioned for the second time. The membrane lifting pressure plate device 20 flattens the membrane bag, and the membrane side pull claw 24 holds the membrane bag. At this time, the membrane lifting pressure plate device 20 resets, and the membrane side pull device 17 moves to transport the membrane bag to the membrane and guide cloth docking platform 19.

[0109] 10: The diaphragm side-pulling device 17 and the diaphragm side-pulling jaw 24 are reset.

[0110] Note that in the above process, steps 2-10 can be operated simultaneously, which greatly improves the overall roll film production cycle time.

[0111] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

Therefore, a feature defined as "primary" or "secondary" may explicitly or implicitly include at least one of that feature. In the description of this invention, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0113] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0114] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art.
