Description

Technical Field

[0001] This invention relates to the field of filter membrane winding, specifically to a filter membrane production winding device. Background Technology

[0002] In fields such as water treatment, biomedicine, food processing, and air purification, filtration membranes serve as core separation elements, and their performance directly determines the separation and purification effect. Multilayer stacked filtration membranes are the mainstream development direction. By combining membrane layers with different pore sizes and materials, a membrane structure with "gradient retention" and "composite functions" is formed, significantly improving filtration efficiency and applicability.

[0003] In the production of multilayer stacked filter membranes, the winding process is a crucial link between membrane sheet processing and subsequent finished product assembly: multiple membrane layers need to be integrated into a continuous roll for subsequent cutting into filter cartridges or further processing into membrane modules. In existing technologies, the method for winding multilayer membranes is the multilayer stacking winding method. The first step involves cutting the continuous original membrane into equal-length single-segment membrane sheets according to a preset size; the second step involves stacking the cut membrane segments one by one in a preset order; and the third step involves manually transporting the stacked membrane assembly to the winding shaft of the winding equipment, starting the winding machine to wind the membrane assembly into a roll, thus completing the multilayer stacking winding.

[0004] However, the "feeding" process of existing multi-layer stacked winding methods is highly dependent on manual labor: during feeding, the stacked film units need to be manually moved to the winding shaft, and the relative positions of the film units and the central cylinder need to be manually adjusted. This is not only labor-intensive, but also results in low overall production efficiency. Existing winding equipment lacks a dynamic pressure regulation mechanism: air is easily left inside the roll after winding, which can easily lead to film layer separation and reduced throughput during subsequent use. Moreover, as the film layer thickness increases during the winding process, the pressure of the winding shaft on the film unit cannot be adjusted synchronously, which can easily lead to problems such as "outer film relaxation" and "inner film extrusion deformation", resulting in poor roll flatness. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a filter membrane production winding device.

When the feeding mechanism abuts against the auxiliary winding mechanism during feeding, it drives the auxiliary winding mechanism to move upward to make room for the filter membrane, and when the feeding mechanism resets, the auxiliary winding mechanism moves downward to abut the filter membrane against the central cylinder.

[0009] As an improvement, a second sliding groove is provided horizontally on the sliding folding plate, and a third sliding groove is connected to one end of the second sliding groove near the central cylinder. The third sliding groove is set at an obtuse angle to the second sliding groove. The feeding mechanism includes a screw block driven by a driving mechanism and slidably disposed in the sliding folding plate. The screw block is provided with a guide plate through a connecting block. The connecting block and the guide plate are rotatably connected. The end of the guide plate is provided with a clamping mechanism that can clamp the filter membrane.

[0010] As an improvement, the clamping mechanism includes a turntable, on which a bidirectional screw and a motor driving the bidirectional screw are provided. A clamping block is connected to the bidirectional screw via a corresponding thread. A feeding top rod located on one side of the bidirectional screw is fixed to the turntable. A guide rod is provided on the guide plate that alternately slides in slide groove three and slide groove two. A toothed ring is provided on the arc-shaped surface of the turntable. A rack that can mesh with the toothed ring is provided above slide groove three.

[0011] As an improvement, the auxiliary winding mechanism includes a telescopic block that is slidably inserted into the housing. The top of the telescopic block is provided with an extension plate, and the end of the extension plate is provided with a sliding block. The sliding block is provided with an extension rod, and the bottom of the extension rod is provided with a tightening member 1 that abuts against the central cylinder and the abutment part is in the shape of an arc plate. The telescopic block is driven by a driven mechanism located below the telescopic block.

[0012] As an improvement, the sliding block is provided with a groove, the end of the extension plate is located in the groove and a sliding rod passing through the extension plate is provided in the groove, and the sliding rod is sleeved with a spring located at the bottom of the extension plate.

[0013] As an improvement, the driven mechanism includes a worm gear located at the bottom of the housing 2, a lead screw 3 that is threadedly connected to the telescopic block on the worm gear, a worm gear meshing with one side of the worm gear, a transmission gear 2 at the end of the worm gear, a toothed plate that meshes with the transmission gear 2 inserted into the housing 2, an end block 2 at one end of the toothed plate, a limit block on the housing 2, a plug rod that is inserted into the limit block on the end block 2, a spring 3 sleeved on the plug rod, and a tightening member 2 between the corresponding extension rods, with square keys at both ends of the tightening member 2 and the square keys being inserted into the keyways of the extension rods.

[0014] As an improvement, the drive mechanism includes a lead screw 2 located inside the sliding folding plate and threadedly connected to the screw block. One end of the lead screw 2 is provided with a bevel gear 3. Two transmission rods connected by keyways are provided on the side wall of the base body. Several sliders are rotatably connected to the transmission rods, and the transmission rods are driven by a motor. The sliders and the motor are slidably connected to the base body. A bevel gear 1 is provided on the transmission rod. A right-angle block is rotatably connected to the transmission rod. A bevel gear 2 is provided on the right-angle block and is connected by a shaft and distributed on the upper and lower sides of the right-angle block. The bevel gear 1 and the bevel gear 3 are respectively meshed with two bevel gears 2.

[0015] The advantages of this invention compared to the prior art are as follows:

[0016] 1. This invention achieves fully automated feeding through a feeding mechanism: the clamping block of the clamping mechanism clamps the end of the filter membrane, and the drive mechanism, through a lead screw and bevel gear transmission, drives the guide plate to move horizontally along the second slide groove and upward along the third slide groove. This, combined with the meshing of the gear ring and rack, enables the turntable to rotate, ensuring the filter membrane end accurately turns and fits the central cylinder. The entire feeding process requires no manual intervention, and the feeding mechanism can pre-position the filter membrane before winding, significantly shortening the process interval and greatly improving feeding efficiency compared to manual methods. It also avoids the deviation problems associated with manual alignment.

[0017] 2. The clamping structure of the present invention has self-adaptive capability: Firstly, by rotating the lead screw, the rotating shaft and the sliding folding plate move synchronously. With the help of the bidirectional lead screw, the parallel adjustment of the two side correction plates can be ensured, which can adapt to filter membranes of different widths. There is no need to disassemble and adjust the clamps, thus improving the versatility of the equipment.

[0018] 3. The auxiliary winding mechanism of the present invention operates through three steps: "giving way - fixing - dynamic tightening". During feeding, the feeding mechanism drives the telescopic block to move upward to make way for the filter membrane. After the filter membrane is attached to the central cylinder, the telescopic block moves downward to press the edge of the filter membrane onto the central cylinder coated with epoxy resin, preventing the edge from warping. During the winding process, when the thickness of the filter membrane increases, the second spring is compressed to make the first tightening member move upward synchronously with the filter membrane, and the pressure increases with the increase of thickness to ensure that each layer of filter membrane is tightened.

[0019] 4. This invention integrates the coating and winding processes: the output nozzle of the auxiliary winding mechanism is connected to the epoxy resin dispensing machine. Before winding, the drive motor rotates the central cylinder, and the nozzle simultaneously and evenly coats the end of the central cylinder with epoxy resin. When the filter membrane is fed, it is directly attached to the coating area, and the auxiliary winding mechanism immediately presses and fixes it. The coating and winding processes are seamlessly connected, eliminating the need for manual coating. Attached Figure Description

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] In the prior art, before winding up multi-layer filter membranes, a multi-layer stacking winding method is generally used. The specific operation process is generally to cut the filter membrane, then stack the cut filter membranes, and finally place the stacked filter membranes on the winding shaft and start the winding equipment to wind them up.

[0035] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 As shown:

[0036] A filter membrane production winding device includes a device base 1, a clamping and winding mechanism 2 for winding the filter membrane on the device base 1, a central cylinder 3 clamped on the clamping and winding mechanism 2 and the filter membrane wound around the central cylinder 3, a straightening side plate 4 correspondingly provided on the device base 1 and the two straightening side plates 4 are driven by the clamping and winding mechanism 2 to move relative to each other, a feeding mechanism 6 for feeding the filter membrane on the straightening side plate 4, a driving mechanism 7 at the end of the device base 1, a transmission mechanism 5 on the straightening side plate 4, the driving mechanism 7 can drive the feeding mechanism 6 to work, an auxiliary winding mechanism 8 at the end of the straightening side plate 4 for tightening the filter membrane during the winding process, the auxiliary winding mechanism 8 is driven by the feeding mechanism 6, and after the feeding mechanism 6 abuts against the auxiliary winding mechanism 8 during feeding, it can drive the auxiliary winding mechanism 8 to move upward so that the auxiliary winding mechanism 8 makes room for the filter membrane, and when the feeding mechanism 6 resets, the auxiliary winding mechanism 8 moves downward so that the filter membrane abuts against the central cylinder 3.

[0037] The auxiliary winding mechanism 8 is equipped with an output nozzle that can coat the end of the central cylinder 3 with epoxy resin. The output nozzle is connected to the epoxy resin dispensing machine.

[0038] The working principle of this invention is as follows: By manually adjusting the clamping and winding mechanism 2, the distance between the two straightening side plates 4 is changed. At this time, the two straightening side plates 4 with the changed distance can match filter membranes with different widths. Then, the feeding mechanism 6 is operated to clamp the filter membrane. After clamping, the drive mechanism 7 is started, which drives one end of the filter membrane to move towards the central cylinder 3 through the feeding mechanism 6. The feeding mechanism 6 first moves horizontally along the straightening side plate 4. Then, the feeding mechanism 6 tilts upward along the straightening side plate 4. When the tilting is in place, the moving direction of the feeding mechanism 6 coincides with the central cylinder 3. While the feeding mechanism 6 tilts upward, the feeding mechanism 6 drives the end of the filter membrane to rotate clockwise under the action of the straightening side plate 4 until the end face of the filter membrane faces the central cylinder 3 and abuts against the central cylinder 3.

[0039] The auxiliary winding mechanism 8 is initially positioned to abut against the central cylinder 3. Before feeding the filter membrane, the clamping winding mechanism 2 and the epoxy resin dispensing machine need to be activated. The clamping winding mechanism 2 drives the central cylinder 3 to rotate, and the epoxy resin dispensing machine applies epoxy resin to the end of the central cylinder 3 through the output nozzle to facilitate the subsequent bonding and winding of the filter membrane. When the feeding mechanism 6 moves the filter membrane, it can abut against the auxiliary winding mechanism 8 and drive the auxiliary winding mechanism 8 to move upward. As the filter membrane moves towards the central cylinder 3, the auxiliary winding mechanism 8 moves upward and disengages from the central cylinder 3. After that, the filter membrane contacts the central cylinder 3. After contact, the feeding mechanism 6 resets and the auxiliary winding mechanism 8 moves downward. The auxiliary winding mechanism 8 can press the filter membrane onto the central cylinder 3. Activating the clamping winding mechanism 2 can then wind up the filter membrane.

[0040] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 Appendix Figure 12 As shown:

[0041] The device base 1 includes a base body 101, and the clamping and winding mechanism 2 includes a box 201 correspondingly disposed on the base body 101. A rotating shaft 202 is inserted through the box 201. One of the rotating shafts 202 is provided with a drive tooth 204. The drive tooth 204 is externally meshed with a transmission gear 205. The transmission gear 205 is driven by a drive motor through gears. A limiting member 206 located above the transmission gear 205 is fixedly connected to the box 201. The two rotating shafts 202 clamp the central cylinder 3 through a clamp.

[0042] The clamping and winding mechanism 2 also includes an end block 203 located at the end of the rotating shaft 202. A rotating rod 207 is rotatably provided inside the base body 101. Both ends of the rotating rod 207 are provided with lead screws 208 that mesh with the end block 203. The straightening side plate 4 includes a sliding folding plate 401 that moves on the base body 101. A box 402 is provided at the end of the sliding folding plate 401. A connecting ring that is rotatably connected to the rotating shaft 202 is provided on the box 402. An adjusting end is provided on the lead screw 208, and when the lead screw 208 rotates, it can simultaneously drive the rotating shaft 202 and the sliding folding plate 401 to move.

[0043] A transmission mechanism 5 is provided at one end of the base body 101 away from the central cylinder 3. The transmission mechanism 5 includes a bidirectional lead screw 501 that is threadedly connected to two sliding folding plates 401. Both the end of the bidirectional lead screw 501 and the lead screw 208 are provided with transmission wheels 209. A transmission belt 502 is provided between the two transmission wheels 209.

[0044] To enable the present invention to wind up filter membranes of different widths, an adjustable-gap straightening side plate 4 is provided. The straightening side plate 4 is driven by the clamping and winding mechanism 2 and the transmission mechanism 5. Specifically, one lead screw 208 is rotated, which, through a rotating rod 207, causes the other lead screw 208 to rotate simultaneously. The lead screw 208, by driving the end block 203, moves both rotating shafts 202 simultaneously, changing the distance between the two rotating shafts 202. Afterward, the central cylinder 3 can be fixed on the clamp, and the distance between the two rotating shafts 202 is adjusted. While the filter membrane is being modified, the rotating shaft 202 can drive the sliding folding plate 401 to move through the connecting ring. The distance between the two sliding folding plates 401 is the width of the filter membrane. In order to keep the two sliding folding plates 401 parallel during movement, a transmission mechanism 5 is provided. When the lead screw 208 rotates, it can drive the bidirectional lead screw 501 to rotate through the transmission wheel 209 and the transmission belt 502. At this time, the bidirectional lead screw 501 and the rotating shaft 202 can drive the two ends of the sliding folding plate 401 to move simultaneously, ensuring the stability of the sliding folding plate 401 during movement.

[0045] When the clamping and winding mechanism 2 is performing winding work, the drive motor can be started to drive the transmission gear 205 to rotate. The transmission gear 205 meshes with the drive gear 204 to drive the rotating shaft 202 to rotate, thereby completing the winding function. Since the transmission gear 205 and the drive gear 204 are meshed and have a sliding connection in the axial direction, when adjusting the distance between the two rotating shafts 202, the drive gear 204 can move relative to the transmission gear 205.

[0046] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 As shown:

[0047] A second sliding groove 403 is horizontally provided on the sliding folding plate 401. A third sliding groove 404 is connected to one end of the second sliding groove 403 near the central cylinder 3. The third sliding groove 404 is set at an obtuse angle with the second sliding groove 403. The feeding mechanism 6 includes a screw block 601 driven by the driving mechanism 7 and slidably provided in the sliding folding plate 401. The screw block 601 is provided with a guide plate 602 through a connecting block. The connecting block and the guide plate 602 are rotatably connected. The end of the guide plate 602 is provided with a clamping mechanism that can clamp the filter membrane.

[0048] The clamping mechanism includes a turntable 603, on which a bidirectional screw 605 driven by a motor is provided. A clamping block 606 is threadedly connected to the bidirectional screw 605. A feeding push rod 607 located on one side of the bidirectional screw 605 is fixedly connected to the turntable 603. A guide rod 612 is provided on the guide plate 602, which alternately slides in the slide groove 3 404 and the slide groove 2 403. A gear ring 611 is provided on the arc surface of the turntable 603. A rack 405 that can mesh with the gear ring 611 is provided above the slide groove 3 404.

[0049] The guide plate 602 is provided with a limiting hole 610, and the feeding push rod 607 is provided with a spring 608. The end of the spring 608 is provided with a limiting rod 609 that extends out of the feeding push rod 607 and is inserted into the limiting hole 610.

[0050] Working principle of feeding mechanism 6: The feeding mechanism 6 is driven by the drive mechanism 7. When feeding the filter membrane, the end of the filter membrane needs to be clamped by the clamping mechanism. Specifically, the filter membrane is placed between two clamping blocks 606. The motor is started and the clamping blocks 606 are driven by the bidirectional screw 605 to clamp the end of the filter membrane. After clamping, the drive mechanism 7 can be started.

[0051] When the drive mechanism 7 is activated, it drives the screw block 601 to move along the sliding folding plate 401. At this time, the connecting block and the guide rod 612 can move along the second slide groove 403. When the guide rod 612 enters the third slide groove 404, the guide plate 602 tilts upward, that is, the guide plate 602 flips upward. At the same time, the gear ring 611 meshes with the rack 405, and while the guide rod 612 moves in the third slide groove 404, the gear ring 611 can roll on the rack 405. The gear ring 611 drives the clamping mechanism to rotate. Figure 9 As shown, the clamping mechanism rotates clockwise, that is, the feeding rod 607 revolves clockwise around the axis of the turntable 603. During the revolution, the feeding rod 607 first abuts against the filter membrane, and after abutting, the filter membrane is wrapped around the feeding rod 607. Since the slide groove 3 404 and slide groove 2 403 are set at an obtuse angle, and the extension direction of slide groove 3 404 intersects and overlaps with the axis of the central cylinder 3 at a point, when the filter membrane on the feeding rod 607 abuts against the central cylinder 3, the filter membrane can be bonded to the central cylinder 3, and the feeding rod 607 is located on the extension line of slide groove 3 404 at this time.

[0052] When the gear ring 611 rotates to perform the feeding operation, it can drive the limiting rod 609 to disengage from the limiting hole 610. When the gear ring 611 is fed and reset, the limiting rod 609 is inserted into the limiting hole 610 under the action of the spring 608. At this time, the gear ring 611 can maintain a stable state under the action of the insertion of the limiting hole 610 and the limiting rod 609.

[0053] After the filter membrane contacts the central cylinder 3, the starting motor reverses to disengage the clamping blocks 606 from the filter membrane. At this time, the end of the filter membrane springs back to move from between the two clamping blocks 606 to above the central cylinder 3. Under the action of epoxy resin, one end of the filter membrane adheres to the central cylinder 3, but because the end of the filter membrane is in a natural state, it cannot completely adhere to the central cylinder 3. The starting motor makes the two clamping blocks 606 adhere together, and then the drive mechanism 7 is started to reverse to reset the feeding mechanism 6. During the reset of the feeding mechanism 6, the clamping mechanism also resets, that is, the turntable 603 reverses. At this time, the filter membrane is located below the clamping blocks 606.

[0055] The auxiliary winding mechanism 8 includes a telescopic block 801 that is slidably inserted into the housing 402. The top of the telescopic block 801 is provided with an extension plate 802. The end of the extension plate 802 is slidably provided with a sliding block 803 located above the central cylinder 3. The sliding block 803 is provided with an extension rod 807. The bottom of the extension rod 807 is provided with a tightening member 808 that abuts against the central cylinder 3 and the abutment part is in the shape of an arc plate. The telescopic block 801 is driven by a driven mechanism located below the telescopic block 801.

[0056] The sliding block 803 is provided with a groove 804, the end of the extension plate 802 is located in the groove 804 and a sliding rod 805 passing through the extension plate 802 is provided in the groove 804, and a spring 806 located at the bottom of the extension plate 802 is sleeved on the sliding rod 805.

[0057] The driven mechanism includes a worm gear 809 located at the bottom of housing 402. The worm gear 809 is provided with a lead screw 810 that is threadedly connected to the telescopic block 801. A worm 811 is meshed with one side of the worm gear 809. A transmission gear 812 is provided at the end of the worm 811. A toothed plate 813 is slidably inserted into housing 402 and meshes with the transmission gear 812 at its bottom. A second end block 814 is provided near one end of the toothed plate 813 that can abut against the lead screw 601. A limiting block 815 is provided on housing 402. A plug rod 816 is provided on the second end block 814 that is inserted into the limiting block 815. A spring 817 located between the second end block 814 and the limiting block 815 is sleeved on the plug rod 816. A tightening member 818 is provided between the corresponding extension rods 807. A square key 819 is provided at both ends of the tightening member 818 and the square key 819 is inserted into the keyway of the extension rod 807.

[0058] When the feeding mechanism 6 is performing the feeding step, the epoxy resin dispensing machine can be started to output epoxy resin through the output nozzle to the end of the central cylinder 3, and at the same time the drive motor is started to drive the central cylinder 3 to rotate, so that epoxy resin can be coated all around the end of the central cylinder 3.

[0059] When the feeding mechanism 6 performs the feeding step, the screw block 601 can abut against the end block 814 and continue to push the end block 814 to move when it abuts against the end block 814. The end block 814 drives the transmission gear 812 and the worm 811 to rotate simultaneously through the toothed plate 813. At the same time, the spring 817 is gradually compressed. The worm 811 drives the worm wheel 809 to rotate. The screw 810 on the worm wheel 809 is threadedly connected to the telescopic block 801, which can drive the telescopic block 801 to move upward. At this time, the tightening part 808 is separated from the central cylinder 3, and the filter membrane can adhere to the central cylinder 3.

[0060] When the feeding mechanism 6 is reset, the screw block 601 gradually moves away from the central cylinder 3. At this time, the end block 814 gradually resets under the action of the spring 817, that is, the telescopic block 801 gradually moves down. When the tightening part 808 contacts the filter membrane and presses the curled edge of the filter membrane onto the central cylinder 3, the curled edge of the filter membrane can be attached to the central cylinder 3 under the action of epoxy resin, and the spring 806 is in an uncompressed state.

[0061] At this point, the drive motor can be started to rotate the central cylinder 3 to achieve the winding of the filter membrane. During the winding process, under the sliding friction between the tightening member 808 and the filter membrane, the filter membrane will be gradually tightened, and the filter membrane will gradually be stacked layer by layer, resulting in an increase in thickness. At this time, the filter membrane will push against the tightening member 808. When the tightening member 808 moves upward, it will drive the sliding block 803 to move upward relative to the extension plate 802 through the extension rod 807. At this time, the spring 806 will be gradually compressed. At the same time, under the action of the spring 806, the downward pressure of the tightening member 808 on the filter membrane will also gradually increase, that is, the sliding friction between the tightening member 808 and the filter membrane will increase, which is more conducive to the tightening work when winding the filter membrane.

[0062] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 7 Appendix Figure 8 Appendix Figure 12 As shown:

[0063] The drive mechanism 7 includes a second lead screw 706 rotatably disposed within the sliding folding plate 401 and threadedly connected to the screw block 601. A third bevel gear 707 is provided at the end of the second lead screw 706 away from the central cylinder 3. Two transmission rods 701 connected by keyways are provided on the side wall of the base body 101. Several sliders 702 are rotatably connected to the transmission rods 701, and one of the transmission rods 701 is driven by a motor. The sliders 702 and the motor are slidably connected to the side wall of the base body 101. A first bevel gear 703 is provided on the transmission rod 701. A right-angle block 704 is rotatably connected to the transmission rod 701. A second bevel gear 705 is provided on the horizontal section of the right-angle block 704 and is connected by a shaft and distributed on the upper and lower sides of the right-angle block 704. The first bevel gear 703 and the third bevel gear 707 are respectively meshed with the two second bevel gears 705.

[0064] When the drive mechanism 7 is working, the start motor drives the two transmission rods 701 connected by keyways to rotate simultaneously. The transmission rods 701 drive the bevel gear 705 to rotate through the first bevel gear 703. The second bevel gear 705 drives the lead screw 706 to rotate through the third bevel gear 707. The lead screw 706 can then drive the screw block 601 to move. When it is necessary to change the distance between the two sliding folding plates 401, the two transmission rods 701 connected by keyways can be extended or retracted. In order to ensure that the second bevel gear 705 can always mesh with the third bevel gear 707, the right-angle block 704 needs to be fixedly connected to the sliding folding plate 401.

[0065] The base body 101 is provided with a sliding groove 102 and a through groove 103. The bidirectional lead screw 501 is located in the sliding groove 102, and the right-angle block 704 passes through the through groove 103 and is slidably connected to the through groove 103.

[0066] In the specific implementation of this filter membrane production winding device, firstly, the spacing of the straightening side plates 4 is adjusted according to the width of the filter membrane. One of the lead screws 208 is rotated, which in turn drives the two rotating shafts 202 to move and adjust the spacing. At the same time, the rotating shafts 202 drive the sliding folding plate 401 to move through the connecting ring, and the lead screw 208 drives the bidirectional lead screw 501 to rotate through the transmission wheel 209 and the transmission belt 502, ensuring that the sliding folding plate 401 remains parallel when moving. After the adjustment is completed, the center cylinder 3 is fixed between the two rotating shafts 202 by the clamp. Next, the epoxy resin dispensing machine is started, and at the same time, the drive motor is started to drive the transmission gear 205 to rotate. The transmission gear 205 meshes with the drive gear 204, causing the rotating shaft 202 to drive the center cylinder 3 to rotate. The output nozzle evenly coats the end of the center cylinder 3 with epoxy resin. Then, the feeding operation is carried out. The end of the filter membrane is placed between the two clamping blocks 606 of the clamping mechanism. The motor is started to drive the bidirectional screw 605 to clamp the filter membrane with the clamping blocks 606. The motor of the drive mechanism 7 is started. The transmission rod 701 drives the lead screw 706 to rotate through the first bevel gear 703, the second bevel gear 705 and the third bevel gear 707. The lead screw 706 drives the screw block 601 to move along the sliding folding plate 401. The connecting block and the guide rod 612 first slide along the second slide groove 403. After entering the third slide groove 404, the guide plate 602 tilts upward. The gear ring 611 meshes with the rack 405 to drive the turntable 603 to rotate, so that the end of the filter membrane faces the central cylinder 3. During the feeding process, screw block 601 abuts against end block 814, pushing toothed plate 813 to move. Toothed plate 813 drives transmission gear 812, worm 811, and worm wheel 809 to rotate. Worm wheel 809 drives telescopic block 801 to move upward through lead screw 810, causing tightening member 808 to disengage from central cylinder 3 to make room for filter membrane. When filter membrane contacts central cylinder 3, clamp block 606 releases, and filter membrane is initially bonded under the action of epoxy resin. Feeding mechanism 6 resets, end block 814 resets under the action of spring 817, telescopic block 801 moves downward, and tightening member 808 and tightening member 818 press filter membrane onto central cylinder 3. Finally, drive motor is started to rotate central cylinder 3 for winding. During winding, the thickness of filter membrane increases, pushing tightening member 808 upward. Spring 806 compresses, increasing the pressure of tightening member 808 on filter membrane, ensuring filter membrane is tightened and wound.
