Description

Technical Field

[0001] The invention relates to the technical field of water purification filter element manufacturing equipment, and in particular to a filter element rolling mechanism. Background Art

[0002] Nowadays, whether it is industrial production, such as the production of products in many industries such as biology, medicine, petroleum, chemical industry, semiconductor, etc. that have strict requirements on water, or scientific research institutes, laboratories, and even our daily life, the requirements for water quality are getting higher and higher. Therefore, we need to purify the water to remove various toxic and harmful substances and impurities in it to meet the requirements of our application. In a water purification device, a filter element made of membrane and guide cloth is used to filter the raw water.

[0003] The Chinese patent with the publication number CN220375888U discloses a filter element winding machine, including a control console and a winding drum for winding the filter element, the top of the control console is provided with a rotating mechanism, the top of the rotating mechanism is fixedly connected with a rotating shaft, and both sides of the rotating shaft are fixedly connected with a limit. When in use, the pull block is pulled, and the movement of the pull block can cause the fixed block to slide in the inner wall of the fixed groove. At this time, the fixed spring can be compressed, and then the required winding drum is sleeved on the surface of the rotating shaft so that the limit rod fits with the inner wall of the limit opening. After the winding drum is fixed, the fixed block can slide out from the inner wall of the fixed groove under the action of the fixed spring, and the winding drum can be fixed by cooperating with the connecting ring and the mounting ring. Finally, the rotating motor is started to carry out the operation of winding the filter element.

[0004] This type of winding equipment

[0005] In addition, a Chinese patent with publication number CN117228406A discloses a shaking device and method and a filter element winding device formed therefrom, comprising: a fixed bracket; a shaking assembly, located in the fixed bracket; comprising a shaking motor and a shaking rod, wherein the shaking motor drives the shaking rod to move back and forth, and the moving direction of the shaking rod is perpendicular to the transmission direction of the diaphragm. The reciprocating movement of the shaking rod is used to shake the diaphragm to be wound on the outer layer of the filter element. The shaking process can eliminate the wrinkles of the diaphragm, ensure that the diaphragm can be wound on the outermost layer of the filter element in a stretched state, and effectively ensure the winding quality of the filter element.

[0006] For the filter element winding equipment in the prior art, if glue needs to be applied to the membrane before winding, when rolling a multi-membrane filter element, the filter materials will be stacked in order on the flat filter material support surface, and glue will be applied to the membrane or filter material where glue sealing is required. Then the filter material will continue to be stacked upwards and the action will be repeated. Finally, the stacked filter materials are rolled onto the center tube to form a spiral membrane element filter element. This type of winding method is prone to wrinkles when the filter materials are stacked, and the wrinkles cannot be eliminated after glue application. When wound to the center tube, the layers of the filter material have been fixed with glue, and the wrinkles generated by the filter material that has been fixed with glue cannot be eliminated by shaking.

DETAILED DESCRIPTION

[0049] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.

[0050] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of implementation. The change or adjustment of their relative relationship should also be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0051] like Figure 1 , 3 As shown, the filter element of the present application includes a guide cloth and a membrane 102 , wherein the guide cloth includes a rolled guide cloth 104 and a sandwich guide cloth 105 .

[0052] like Figure 2 or Figure 5 As shown, the present invention proposes a filter element rolling mechanism, including an unwinding device 201, a gluing device 204, a feeding device, a winding device 800, a conveying device 402 and a packaging device 500 arranged in sequence on a frame.

[0053] The unwinding device 201 unwinds the rolled guide cloth and film 102. After the unwinding guide cloth and film 102 pass through the transition roller 202, the guide cloth and film 102 are arranged in an upper and lower interval and flow to the feeding device. The unwinding device 201 is relatively mature in the prior art and will not be described in detail here.

[0054] The glue applying device 204 is arranged between the unwinding device 201 and the feeding device. The glue applying device 204 can be a glue applying head installed on an industrial robot. After the glue applying route is edited for the industrial robot, the industrial robot can drive the glue applying head to set glue lines 103 on the guide cloth and the diaphragm 102. The glue applying on the equipment is continuous. After the glue applying of the previous one is completed, the glue applying of the next membrane element will continue. Moreover, glue can be applied on both the diaphragm 102 and the guide cloth, and finally a pure water area with three closed sides and one open side can be formed, or a pure water area of ​​other shapes can be formed according to needs.

[0055] In order to correct the guide cloth and the membrane 102 after unwinding, a set of correction components 203 is provided between the unwinding device 201 and the glue-applying device 204. The set of correction components 203 are spaced apart up and down, so that each layer of filter material can be corrected by a corresponding correction component 203. Figure 2In the embodiment, there are two sets of deviation-correcting components 203, which are arranged between the gluing device 204 and the unwinding device 201, and between the gluing device 204 and the feeding device. Figure 5 In the embodiment, there is a set of deviation correction components 203, which are arranged between the gluing device 204 and the unwinding device 201.

[0056] The feeding device includes a traction component, a cutting component, and a fixing component. Specifically, the guide cloth and the diaphragm 102 first pass through the fixing component. When winding begins, the traction component transports the front end of the guide cloth and the diaphragm 102 to the winding device 800. The front end of the guide cloth is fixed to the central tube 101 on the winding device 800. Then the winding device 800 drives the central tube 101 to rotate, and the guide cloth and the diaphragm 102 are wound onto the central tube 101 together to form a filter element.

[0057] When the filter element is wound to the set length, that is, when the filter element is about to be wound, the guide cloth and the diaphragm 102 need to be cut off. The fixing assembly fixes the guide cloth and the diaphragm 102 between the winding device 800 and the glue-applying device 204, and then the cutting assembly cuts off the guide cloth and the diaphragm 102 between the fixing assembly and the winding device 800. Then the winding device 800 continues to drive the central tube 101 to rotate, and the remaining part of the cut guide cloth and the diaphragm 102 is wound. At this time, the filter element is completely wound, and the outside of the filter material is fixed to prevent it from spreading. Then remove the wound filter element on the winding device 800, replace the new central tube 101, and then use the traction assembly to traction the front end of the guide cloth and the diaphragm 102 fixed on the fixing assembly, let the fixing assembly loosen the guide cloth and the diaphragm 102, and the traction assembly tractions the guide cloth and the diaphragm 102 onto the central tube 101 to start the next round of winding.

[0058] The filter material of the present invention is not stacked immediately after being glued. After the filter material is wound around the central tube 101, each layer of the filter material is tightly attached together, and the glue bonds the adjacent layers together. This can avoid the displacement of the glue line caused by direct stacking after the glue is applied on the surface of the filter material, especially for flexible filter materials, it can avoid the formation of more wrinkles on the surface of the filter material after glue bonding. At the same time, by clamping the tail, it can also ensure that the tail of the filter material is less displaced during the rolling process, which plays a role in correcting deviation.

[0059] like Figure 2 As shown, the filter element rolling mechanism of the present invention also includes a central tube storage bin 401 and a filter element storage bin 403. The central tube 101 in the central tube storage bin 401 is transported to the winding device 800 by the conveying device 402. When the filter element on the winding device 800 is wound, the packaging device 500 packages the outer side of the wound filter element to prevent the diaphragm 102 and the guide cloth from spreading out, and then the packaged filter element is transferred to the filter element storage bin 403 by the conveying device 402.

[0060] The conveying device 402 in the present invention can be made by installing a clamp on an industrial robot, or other designs in the prior art can be adopted, which are relatively mature in the prior art and will not be limited or elaborated herein.

[0061] As an alternative, Fig. 9 As shown, the winding device 800 includes a first winding linear drive module 801 arranged opposite to each other, and the first winding linear drive module 801 is used to drive a pair of winding jaw drive assemblies 802 to move toward or away from each other. The winding jaw drive assembly 802 is used to drive the winding jaw 803 to clamp the central tube and drive the central tube to rotate, which can be achieved by connecting a multi-jaw chuck to the output shaft of a motor, which is relatively mature in the prior art and will not be limited or repeated here.

[0062] The winding device 800 also includes a welding assembly 804, which is used to fix the front end of the guide cloth pulled by the pulling assembly to the central tube 101 and fix the outer filter material of the filter element. The welding assembly 804 can be ultrasonic welding, or other designs in the prior art that can achieve the fixing of the filter material, which will not be limited or repeated here.

[0063] When the conveying device 402 conveys the central tube 101 to the winding device 800, the first linear drive module 801 drives a pair of winding jaw drive assemblies 802 to move toward each other, and the winding jaw drive assemblies 802 clamp the two ends of the central tube 101, and then the conveying device 402 releases the central tube 101 and leaves. The traction assembly pulls the front end of the guide cloth to the central tube 101, the welding assembly 804 fixes the front end of the guide cloth to the central tube 101, and then the traction assembly also pulls the diaphragm 102 to the central tube 101, and the winding jaw drive assembly 802 drives the central tube 101 to rotate, and starts to wind the filter material.

[0064] As an alternative, Figure 8 As shown, the packaging device 500 includes a film unwinding roller 501 , a film conveying component 505 , a film cutting component 506 , a static electricity eliminating component 504 , and a film transition roller 503 .

[0065] The film unwinding roller 501 and the film transition roller 503 are hinged to the frame. The film 502 unwound by the film unwinding roller 501 passes through the film transition roller 503 and is then pulled and transported by the film conveying assembly 505 .

[0066] The film conveying assembly 505 is installed on the frame, and the film conveying assembly 505 is used to send the film 502 to the winding device 800 for winding. The film conveying assembly 505 can include a multi-axis moving mechanism and a film clamping mechanism, which is relatively mature in the prior art and will not be repeated here. After the cut diaphragm 102 and the guide cloth are all wound on the central tube 101, the film conveying assembly 505 sends the film 502 to one side of the rolled filter element, and the central tube 101 continues to rotate. At the same time, the film clamping mechanism of the film conveying assembly 505 releases the film 502. When the central tube 101 rotates, the film 502 is wound around the outside of the filter element for several turns to complete the packaging. At this time, the diaphragm 102 and the guide cloth can be prevented from spreading.

[0067] The film cutting assembly 506 is installed on the frame. When the packaging is completed, the central tube 101 stops rotating, and the film clamping mechanism of the film conveying assembly 505 clamps the film 502 again. Then the film cutting assembly 506 is used to cut the wound film 502, and the film clamping mechanism clamping the film 502 waits for the next packaging.

[0068] The film cutting assembly 506 is relatively mature in the prior art and will not be described in detail here.

[0069] The packaging device 500 further includes a static elimination component 504 installed on the frame, and the static electricity on the unwound film 502 can be eliminated by the static elimination component 504. The static elimination component 504 is relatively mature in the prior art and will not be described in detail here.

[0070] After the film 502 is cut, the conveying device 402 clamps the packaged filter element and delivers the packaged filter element to the filter element storage bin 403 .

[0071] As an optional solution, the traction assembly includes a vertical first traction drive module 601, which is used to drive the horizontal first traction drive module 602 to perform vertical linear motion along a direction perpendicular to the conveying direction of the guide cloth and the diaphragm 102. The horizontal first traction drive module 602 is used to drive the traction clamp 603 to perform horizontal linear motion along a direction parallel to the conveying direction of the guide cloth and the diaphragm 102. Through the coordinated cooperation of the vertical first traction drive module 601 and the horizontal first traction drive module 602, the front end of the diaphragm 102 and the guide cloth can be pulled to the corresponding position to start rolling.

[0072] For the specific implementation of the feeding device, please refer to the following embodiments:

[0073] Feeding device embodiment 1

[0074] In this embodiment, Figure 3As shown, the fixing assembly includes a plurality of first support columns fixedly connected to the frame, a first lower pressing plate is mounted on the first support column, a vertical first clamping driving module is mounted on the first lower pressing plate, and the vertical first clamping driving module is used to drive the first upper pressing plate 302 to perform vertical linear motion in the direction close to or away from the first lower pressing plate. When winding, let the guide cloth and the diaphragm 102 pass through a group of first lower pressing plates and the first upper pressing plate 302 respectively. When the guide cloth and the diaphragm 102 need to be cut, the first upper pressing plate 302 and the first lower pressing plate are made to clamp the guide cloth and the diaphragm 102.

[0075] In this embodiment, the traction assembly is also used to traction the tail end of the cut membrane 102 so that it is laid flat on the cut guide cloth. When the filter element is about to be wound, that is, when there is about 10 cm of filter material left to be wound, the filter material can be cut, and the cut membrane 102 can be laid flat on the guide cloth, and finally wound together. The cut membrane 102 is laid flat on the guide cloth by the traction assembly, so as to avoid the cut membrane 102 from falling freely and causing wrinkles, deviations, folds and other problems.

[0076] In this embodiment, the cutting assembly includes a vertical first cutting drive module 301 installed on the frame, and the vertical first cutting drive module 301 is used to drive the cutter 303 to perform vertical linear motion perpendicular to the conveying direction of the guide cloth and the membrane 102. Among them, the cutting line is located between the first upper pressing plate 302 and the traction end. When the guide cloth and the membrane 102 need to be cut, the vertical first cutting drive module 301 drives the cutter 303 to cut the membrane 102 and the guide cloth from top to bottom.

[0077] In order to support the diaphragm 102 during cutting, a support plate 304 is provided, which is located below the diaphragm 102. The support plate 304 facilitates the cutter 303 to cut the diaphragm 102, and also prevents the supported diaphragm 102 from being easily wrinkled when being cut.

[0078] Feeding device embodiment 2

[0079] This embodiment includes the solution in the first embodiment of the feeding device, and further includes a base-integrated mobile clamping assembly located below the first lower pressing plate at the bottom. The base-integrated mobile clamping assembly is used to synchronously convey the cut film 102 and the tail end of the guide cloth to the winding device 800 .

[0080] Specifically, Figure 4As shown, the base integrated mobile clamping assembly includes a mobile base 701, which can perform transverse linear motion on the frame in a direction parallel to the conveying direction of the guide cloth and the diaphragm 102. Optionally, a linear module can be installed on the frame, and the mobile base 701 is connected to the slider of the linear module. It can also be achieved by other methods, which are relatively mature in the prior art and will not be repeated or limited here.

[0081] A plurality of second support columns 702 are installed on the movable base 701 , and a second lower pressure plate 705 and a vertical second clamping drive module 703 are installed on the second support columns 702 . The vertical second clamping drive module 703 is used to drive the second upper pressure plate 704 to perform vertical linear motion in a direction approaching or away from the second lower pressure plate 705 .

[0082] In this solution, the traction assembly is also used to pull the cut guide cloth and the tail end of the diaphragm 102 so that they are clamped by the second upper pressing plate 704 and the second lower pressing plate 705 .

[0083] It should be noted that in this embodiment, the guide cloth and the diaphragm 102 are cut off from bottom to top in sequence. Specifically, before the filter element is about to be wound, the winding device 800 stops driving the central tube 101 to rotate, and all the first lower pressing plates and the first upper pressing plates 302 are above the base integrated mobile clamping assembly. The first lower pressing plates and the first upper pressing plates 302 first clamp and fix the guide cloth and the diaphragm 102 to be cut, and the bottom layer of the filter material is first cut off, and then the traction assembly pulls the tail end of the bottom layer of the filter material, and the tail end is sent to the second upper pressing plate 704 and the second lower pressing plate 705 of the bottom layer of the base integrated mobile clamping assembly for clamping and fixing. After the filter materials are cut off from bottom to top in sequence, the filter materials are pulled to the corresponding second upper pressing plates 704 and the second lower pressing plates 705 one by one for clamping and fixing. Then the winding device 800 drives the central tube 101 to rotate again, and the movable base 701 moves toward the winding device 800 synchronously. Finally, the second upper pressing plate 704 and the second lower pressing plate 705 release the guide cloth and the diaphragm 102, and the filter element is finally rolled.

[0084] By setting up a base-integrated mobile clamping assembly, the last section of the guide cloth and diaphragm 102 to be wound can be transported up and down at intervals, and the tail end of the guide cloth and diaphragm 102 is also fixed, which can avoid the guide cloth and diaphragm 102 at the tail end from being offset or wrinkled.

[0085] In this scheme, the cutting assembly is different from the cutting assembly in the first embodiment of the feeding device. Specifically, the cutting assembly includes a transverse first cutting drive module installed on the first upper pressing plate 302. The transverse first cutting drive module is connected to a first cutter, and the first cutter is located on the side of the first upper pressing plate 302 close to the winding device 800. This transverse first cutting drive module is used to drive the first cutter to perform transverse linear motion perpendicular to the conveying direction of the guide cloth and the diaphragm 102. That is, this cutting assembly is installed on each first upper pressing plate 302. Since the cutting assembly is installed separately on the first upper pressing plate 302, it is possible to cut the guide cloth and the diaphragm 102 in sequence from bottom to top.

[0086] Feeding device embodiment 3

[0087] In this embodiment, if Figure 5 As shown, the filter element rolling mechanism also includes a split movable clamping assembly, which is used to transport the cut membrane 102 and the tail end of the guide cloth to the winding device 800. Figure 6 , 7 As shown, the split movable clamping assembly includes a guide rail 902 mounted on a frame, on which a plurality of movable slides 903 are mounted, and the movable slides 903 can perform transverse linear motion parallel to the conveying direction of the guide cloth and the membrane 102. The number of movable slides 903 corresponds to the number of groups of filter materials.

[0088] The third support column 904 is mounted on the movable slide 903, and the third lower pressing plate 905 and the third vertical clamping driving module are mounted on the third support column 904. The third vertical clamping driving module is used to drive the third upper pressing plate 906 to perform vertical linear motion in the direction of approaching or moving away from the third lower pressing plate 905. Each set of pressing plates includes the third upper pressing plate 906 and the third lower pressing plate 905, and each set of pressing plates is arranged in an upper and lower interval.

[0089] Attention should be paid to the installation positions of each component in this implementation scheme. For details of the installation positions, please refer to Figure 5 , 6 The fixed component is located on the side of the guide rail 902 away from the winding device 800 , and a relay traction component is also provided between the fixed component and the guide rail 902 .

[0090] When the guide cloth and the diaphragm 102 need to be cut, the split movable clamping assembly and the fixing assembly clamp and fix the guide cloth and the diaphragm 102, and then the cutting assembly is used to cut the guide cloth and the diaphragm 102 on the side of the split movable clamping assembly away from the winding device 800. After the guide cloth and the diaphragm 102 are cut, the movable slide 903 moves toward the winding device 800, so that the last section of the guide cloth and the diaphragm 102 to be wound can be transported up and down, and the tail end of the guide cloth and the diaphragm 102 is also fixed, which can prevent the guide cloth and the diaphragm 102 at the tail end from being offset, and can also prevent the guide cloth and the diaphragm 102 at the tail end from forming wrinkles.

[0091] When the next filter element needs to be wound, the relay traction assembly is used to send the guide cloth and the front end of the diaphragm 102 fixed by the fixing assembly to be pulled by the traction assembly, so that the guide cloth and the front end of the diaphragm 102 pass between the third upper pressing plate 906 and the third lower pressing plate 905, and realize automatic continuous winding. The structure of the relay traction assembly is similar to that of the traction assembly, and will not be repeated here. Of course, the relay traction assembly may not be provided. In this case, it is necessary to manually pass the guide cloth and the front end of the diaphragm 102 fixed by the clamping assembly through the third upper pressing plate 906 and the third lower pressing plate 905, and then send them to be pulled by the traction assembly.

[0092] As an optional solution, the fixed component includes a fourth support column 901 installed on the frame, and a transverse lower pressure plate driving module 912 is installed on the fourth support column 901. The transverse lower pressure plate driving module 912 is used to drive the fourth lower pressure plate 908 to perform transverse linear motion along a direction parallel to the conveying direction of the guide cloth and the diaphragm 102.

[0093] A vertical fourth clamping drive module 909 is installed on the fourth lower pressure plate 908, and the vertical fourth clamping drive module 909 is used to drive the fourth upper pressure plate 907 to make vertical linear motion in the direction of approaching or moving away from the fourth lower pressure plate 908, so as to clamp or loosen the guide cloth and diaphragm 102 passing through the fourth lower pressure plate 908 and the fourth upper pressure plate 907.

[0094] By setting the lateral lower pressure plate driving module 912, the fourth lower pressure plate 908 and the fourth upper pressure plate 907 that clamp and fix the guide cloth and the diaphragm 102 can pull the guide cloth and the diaphragm 102 to feed a certain length, thereby adapting to different rolling conditions.

[0095] Optionally, in this embodiment, the cutting assembly includes a transverse second cutting drive module 910 installed on the fourth upper pressing plate 907, and the transverse second cutting drive module 910 is connected to a second cutter 911, and the second cutter 911 is located on the side of the fourth upper pressing plate 907 away from the winding device 800. The transverse second cutting drive module 910 is used to drive the second cutter 911 to perform transverse linear motion perpendicular to the conveying direction of the guide cloth and the membrane 102, so that the guide cloth and the membrane 102 can be cut off.

[0096] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
