Description

Technical Field

[0001] This invention relates to the field of spiral wound water filter cartridge manufacturing technology, specifically to an automatic tape application device for spiral wound water filter cartridge membranes. 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, wastewater treatment, and the production of pure water for industrial and medical use. Current production line processes require folding the membrane, which necessitates applying tape along the seam to protect the membrane and also to secure the coarse mesh to it. However, the current process requires the membrane to be stationary when applying the tape; it's impossible to accurately apply tape to a membrane that is in motion, thus prolonging the entire filter cartridge production cycle and impacting production line efficiency. Summary of the Invention

[0003] This invention provides an automatic tape-applying device for the membrane of a spiral water filter cartridge, which can solve the technical problem that the membrane needs to be in a static state to apply the center seam tape in the existing split osmosis membrane production process, thereby improving production efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic tape applicator for a spiral-wound water filter cartridge, comprising a substrate, a linear guide rail laterally arranged on the upper front side of the substrate, a tape gripper moving platform slidably arranged on the linear guide rail, a tape gripper assembly mounted on the lower side of the tape gripper moving platform, the tape gripper moving platform being driven by a translation drive assembly to slide back and forth along the linear guide rail, a roller laterally mounted on the lower front side of the substrate, a tape adsorption strip axially mounted on one side of the roller, the tape adsorption strip having evenly distributed vacuum adsorption holes, the roller being driven to rotate by a rotation drive assembly mounted on the substrate, and one end of the roller... A tape cutting assembly is installed on the upper side. A tape reel is installed on the base plate 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. 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.

[0005] Preferably, the end of the roller is connected to a vacuum rotary air connector, and the vacuum adsorption hole on the tape adsorption strip is connected to the vacuum rotary air connector. The vacuum rotary air connector is connected to a vacuum device, which can continuously evacuate air from the vacuum adsorption hole on the tape adsorption strip to form a negative pressure, so that the tape is adsorbed on the tape adsorption strip and will not fall off until the tape is attached to the diaphragm. The rotation of the roller will not affect the normal use of the vacuum rotary air connector.

[0006] Preferably, the tape cutting assembly includes a cutting rotary power cylinder and a tape cutter mounted on one side of the cutting rotary power cylinder. The tape cutter cuts the tape when it rotates toward the roller, which can achieve fast and accurate tape cutting.

[0007] Preferably, a tape fixing and pressing cylinder is installed on the side of the tape cutting assembly near the tape reel to press down the end of the tape cut by the tape cutting assembly. In this way, the tape gripper assembly can accurately grasp the end of the tape each time, ensuring the continuous operation of the production line.

[0008] 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.

[0009] Preferably, the tape guiding assembly includes multiple tape guiding wheels installed between one end of the roller and the tape reel, so that the tape enters at a horizontal angle between the tape cutting assembly and the roller. The tape guiding wheels can be flexibly set and the tension can be adjusted.

[0010] Preferably, the tape guiding assembly further includes a tape pre-folding assembly, which includes a swing member rotatably mounted on a substrate. A folding pressure roller is mounted on the lower end of the swing member, and a folding roller with a V-shaped groove around its circumference is mounted on one side of the folding pressure roller. An elastic member is mounted between the upper end of the swing member and the substrate. The elastic member causes the folding pressure roller to press against the folding roller, forming a folding crease on the surface of the tape that passes over the folding roller. The cooperation between the folding pressure roller and the folding roller to form 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.

[0011] Preferably, the tape guide assembly is also equipped with a tape detection sensor. If the tape being transported by the tape guide assembly is found to be broken or used up, the production line can be stopped immediately.

[0012] Preferably, the translation drive assembly includes a lead screw parallel to the linear guide rail and a lead screw slider mounted on the lead screw. The lead screw slider is connected to the conveyor belt gripper moving platform. One end of the lead screw is connected to a first driven wheel, and a first driving wheel is provided on one side of the first driven wheel. The first driven wheel and the first driving wheel are connected by a first transmission belt. The first driving wheel is driven by a first power motor. A first tensioning wheel that contacts the first transmission belt is also installed on one side of the first driven wheel and the first driving wheel. The lead screw drive enables the conveyor belt gripper moving platform to move back and forth accurately.

[0013] Preferably, the rotary drive assembly includes a second driven wheel mounted on one end of the roller's shaft and a second driving wheel mounted on one side of the second driven wheel. The second driven wheel and the second driving wheel are connected by a second transmission belt. The second driving wheel is driven by a second power motor. A second tensioning wheel that contacts the second transmission belt is also mounted on one side of the second driven wheel and the second driving wheel.

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

[0015] The system is equipped with a tape gripper moving platform and a tape gripper assembly, which cooperate with a roller and a tape adsorption strip. The tape is gripped by the tape gripper assembly and pulled horizontally to the other end of the roller. After being cut by the tape cutting assembly, the tape is adsorbed onto the tape adsorption strip. As the roller rotates, the tape is attached to the conveyed film. The rotation of the roller is matched with the movement rhythm of the tape gripper moving platform, which can continuously attach the tape to the center position of the conveyed film. This invention can achieve non-stop application of tape to the center seam of the film, greatly improving the production cycle, reducing equipment costs, and improving product stability while retaining the original production process.

[0022] 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.

[0023] Currently, the split osmosis membranes of spiral wound water filter cartridges are manufactured using assembly line processes. In this process, the membrane needs to be folded in half, and the folded point is the center seam of the membrane. To protect the membrane, tape needs to be applied to the center seam. The tape also needs to fix the coarse mesh to the membrane, so applying the tape is very important. Current processes also have tape-applying equipment, which presses the tape vertically onto the center line of the membrane. When the tape is pressed down, both the membrane and the coarse mesh need to stop and cannot move until the tape is applied before proceeding. This not only affects production efficiency but also requires adjustments to other processes, making the overall production flow inefficient.

[0024] Therefore, this invention solves the technical problem in existing osmosis membrane production processes that require the membrane to be in a static state before the center seam tape can be applied, thus improving production efficiency. Figure 1-4As shown, the following technical solution is provided: an automatic tape application device for a spiral water filter cartridge membrane, comprising a substrate 1, a linear guide rail 3 horizontally arranged on the upper front side of the substrate 1, a tape gripper moving platform 4 slidably arranged on the linear guide rail 3, a tape gripper assembly 7 installed on the lower side of the tape gripper moving platform 4, the tape gripper moving platform 4 being driven by a translation drive assembly 12 to slide back and forth along the linear guide rail 3, a roller 9 horizontally installed on the lower front side of the substrate 1, a tape adsorption strip 8 axially installed on one side of the roller 9, the tape adsorption strip 8 having evenly distributed vacuum adsorption holes, the roller 9 being driven to rotate by a rotation drive assembly 10 mounted on the substrate 1, and one end of the roller 9 having... A tape cutting assembly 2 is installed on the side. A tape reel 5 is installed on the base plate 1 near the tape cutting assembly 2. A tape guide assembly is provided on the base plate 1 between the tape reel 5 and the tape cutting assembly 2. The tape guide assembly guides the tape on the tape reel 5 to the position of the tape cutting assembly 2. The tape is grasped by the tape gripper assembly 7 and pulled flat to the other end of the roller 9. The tape cut by the tape cutting assembly 2 is adsorbed on the tape adsorption strip 8. As the roller 9 rotates, the tape is attached to the conveyed film. The rotation of the roller 9 matches the movement rhythm of the tape gripper moving platform 4, 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.

[0025] Specifically, the substrate 1 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 9, so the rotation of the roller 9 is matched with the conveying speed of the film and the coarse screen. When the roller 9 drives the tape adsorption strip 8 to rotate to the bottom, it corresponds to the center line position of the film, and the tape can be applied accordingly.

[0026] A side plate can be installed at one end of the base plate 1. Both the translation drive assembly 12 and the rotation drive assembly 10 can be installed on the side plate. At the same time, one end of the roller 9 can also be fixed by the side plate, while the other end of the roller 9 is fixed by the fixing bracket 6 installed on the base plate 1. A pad can be installed on the upper end of the fixing bracket 6. 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, it passes horizontally through the guide groove. Meanwhile, a tape fixing and pressing cylinder 11 is installed on the side of the tape cutting assembly 2 near the tape reel 5 to press down the end of the tape cut by the tape cutting assembly 2. In this way, the tape gripper assembly 7 can accurately grasp the end of the tape each time, ensuring the continuous operation of the production line. The tape fixing and pressing cylinder 11 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 11 to press the end of the tape onto the pad and keep the tape from moving.

[0027] In this embodiment, as Figure 1and 4 As shown, the end of the roller 9 is connected to a vacuum rotary air connector 22. The vacuum adsorption holes on the tape adsorption strip 8 are connected to the vacuum rotary air connector 22. The vacuum rotary air connector 22 is connected to a vacuum device, which can continuously evacuate air from the vacuum adsorption holes on the tape adsorption strip 8 to form a negative pressure, so that the tape is adsorbed on the tape adsorption strip 8 and will not fall off until the tape is attached to the diaphragm. The rotation of the roller 9 will not affect the normal use of the vacuum rotary air connector 22. A connecting pipe can be set inside the roller 9 to connect the vacuum adsorption holes on the tape adsorption strip 8 to the vacuum rotary air connector 22.

[0028] In this embodiment, as Figure 3 As shown, the tape cutting assembly 2 includes a cutting blade rotation power cylinder 13 and a tape cutter 14 installed on one side of the cutting blade rotation power cylinder 13. When the tape cutter 14 rotates towards the roller 9, it cuts the tape, which can achieve fast and accurate tape cutting. When the tape cutter 14 rotates and cuts downwards, the tape adsorption strip 8 is located on the upper side of the roller 9. A groove can be made at the upper end of the tape adsorption strip 8 and the position of the tape cutter 14. When the tape cutter 14 cuts downwards, it falls into the groove, which can ensure that the tape is cut. The blade of the tape cutter 14 can be designed to be serrated.

[0029] In this embodiment, as Figure 3 As shown, the tape gripper assembly 7 includes a tape gripper upper and lower cylinder 71 connected to the tape gripper moving platform 4 and an outer frame 73 mounted on the lower extension rod of the tape gripper upper and lower cylinder 71. A tape clamping wheel 76 is mounted on the lower end of the outer frame 73 near the tape cutting assembly 2. A first gripper cylinder 72 is mounted on the outer frame 73. A second gripper cylinder 74 is mounted on the lower extension rod of the first gripper cylinder 72. A tape gripper component 75 is mounted on the horizontal extension rod of the second gripper cylinder 74 facing the tape clamping wheel 76. The design is ingenious, utilizing the tape gripper upper and lower cylinder 71, the first gripper cylinder 72, and the second gripper cylinder... The alternating use of 74 allows the tape gripper 75 and tape clamping wheel 76 to clamp, pull, and release the end of the tape. Specifically, the tape gripper's upper and lower cylinders 71 can drive the entire outer frame 73 and all components installed inside the outer frame 73 to move up and down. When gripping and releasing the tape, the tape gripper's upper and lower cylinders 71 will descend. When it is necessary to grip the tape, the first gripper cylinder 72 extends, and the second gripper cylinder 74 also extends. When the end of the tape enters between the tape clamping wheel 76 and the tape gripper 75, the first gripper cylinder 72 retracts, so that the tape can be firmly clamped by the tape clamping wheel 76 and the tape gripper 75.

[0030] In this embodiment, as Figure 4As shown, the tape guiding assembly includes multiple tape guide wheels 15 installed between one end of the roller 9 and the tape reel 5, so that the tape enters at a horizontal angle between the tape cutting assembly 2 and the roller 9. The tape guide wheels 15 can be flexibly set and the tension can be adjusted. Specifically, the tape reel 5 can be installed on the upper part of one end of the base plate 1. The tape coming out of the tape reel 5 can be guided downward first, then upward, and then enter the tape cutting assembly 2 and the roller 9 in a horizontal state. The tape guide wheels 15 can be installed at the position where the tape needs to be turned, and the number can be adjusted as needed.

[0031] In this embodiment, the tape guiding assembly further includes a tape pre-folding assembly. The tape pre-folding assembly includes a swing member 17 rotatably mounted on the substrate 1. A folding pressure roller 18 is mounted on the lower end of the swing member 17. A folding roller 19 with a V-shaped groove around its circumference is mounted on one side of the folding pressure roller 18. An elastic member 16 is mounted between the upper end of the swing member 17 and the substrate 1. The elastic member 16 causes the folding pressure roller 18 to press on the folding roller 19, forming a folding crease on the surface of the tape that passes over the folding roller 19. The cooperation of the folding pressure roller 18 and the folding roller 19 forms a folding crease on the surface of the tape, which facilitates the folding of the film in subsequent processes and solves the problem that the tape is not easy to fold in subsequent folding processes.

[0032] In this embodiment, a tape detection sensor 21 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.

[0033] As one specific implementation of the translation drive component 12, such as Figure 1 and 2 As shown, the translation drive assembly 12 includes a lead screw 127 parallel to the linear guide rail 3 and a lead screw slider 126 mounted on the lead screw 127. The lead screw slider 126 is connected to the tape gripper moving platform 4. One end of the lead screw 127 is connected to a first driven wheel 124. A first driving wheel 122 is provided on one side of the first driven wheel 124. The first driven wheel 124 and the first driving wheel 122 are connected by a first transmission belt 123. The first driving wheel 122 is driven by a first power motor 121. A first tensioning wheel 125 that contacts the first transmission belt 123 is also installed on one side of the first driven wheel 124 and the first driving wheel 122. The lead screw drive enables the tape gripper moving platform 4 to move back and forth accurately.

[0034] As one specific embodiment of the rotary drive component 10, such as Figure 1 and 2As shown, the rotary drive assembly 10 includes a second driven wheel 103 mounted on one end of the shaft of the roller 9 and a second driving wheel 104 mounted on one side of the second driven wheel 103. The second driven wheel 103 and the second driving wheel 104 are connected by a second transmission belt 105. The second driving wheel 104 is driven by a second power motor 101. A second tensioning wheel 102 that contacts the second transmission belt 105 is also mounted on one side of the second driven wheel 103 and the second driving wheel 104.

[0035] As the overall workflow of this embodiment:

[0036] Preparation: First, manually install the tape reel 5 onto the chuck. Then, manually pull the tape out from the tape reel 5, around the tape guide assembly and the tape pre-folding assembly. Finally, fix the tape end to the tape fixing and pressing cylinder 11. Manually press down the tape cutter 14 to remove the excess tape end, and then start the equipment.

[0037] Equipment workflow:

[0038] The equipment adjusts preset parameters and starts the translation drive assembly 12 and the rotation drive assembly 10. The rotation drive assembly 10 rotates the tape suction strip 8 to a vertically upward position. Simultaneously, the translation drive assembly 12 clamps the tape head with the tape gripper assembly 7, and the tape gripper's up-and-down cylinder 71 retracts. The translation drive assembly 12 moves the tape gripper assembly 7 to the tape release position and releases the tape head. The vacuum rotary air connector 22 connects to the vacuum, and the cutter rotation power cylinder 13 starts, driving the tape cutter 14 to cut the tape. At the same time, the tape suction strip 8 absorbs the cut tape. At this time, the membrane passes below, and the equipment records the membrane position. After reaching the preset point, the rotation drive assembly 10 rotates the tape suction strip 8 synchronously, applying the tape to the center of the membrane. The cycle repeats.
