Description

Technical Field

[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. In the existing technology, the winding process of filter cartridges involves welding the guide cloth into groups at a welding station, then unfolding the guide cloth layer by layer at the membrane winding station, inserting the folded membrane bags layer by layer at the membrane folding station, covering them with the guide cloth, and applying adhesive to form the membrane fabric. The membrane fabric is then stacked at the stacking station to form a membrane sheet. To ensure filter cartridge performance, the membrane fabric is required to be stacked in a staggered manner, but currently there is no device that can precisely control the staggered stacking of the membrane fabric. The membrane sheet is then transferred to the winding module for winding. Before winding, the membrane sheet also needs to be stacked at the stacking station.

[0044] Please refer to the drawingsFigures 1-6 The application provides a filter core preparation device, which comprises the following components:

[0045] A film cloth stacking part 01 is used for stacking N layers of film cloths in a staggered manner to form a film sheet.

[0046] A film sheet feeding assembly 02 is used for feeding M layers of film sheets to the bottom flow guide cloth.

[0048] A center tube feeding assembly 04 is used for feeding the center tube to the winding assembly.

[0049] A filter core discharging assembly 05 is located on the side, away from the winding station, of the center tube feeding assembly.

[0050] The film cloth stacking part can realize automatic staggered stacking of film cloths, and after the winding station is used for welding the bottom flow guide cloth and the center tube, the film sheet feeding assembly is used for directly stacking the film sheets on the bottom flow guide cloth in a staggered manner, so that the stacking and winding of the film sheets can be completed on the winding station, the stacking process device and time are reduced, and the efficiency of filter core preparation is effectively improved.

[0051] Please refer to the accompanying drawings Figure 2 The film cloth stacking part 02 comprises the following components:

[0052] A support frame 1 is provided with a table slide rail 3 and a table 2 in the table slide rail 3.

[0053] A grabbing assembly is located at the tail of the table 2 and is located in a grabbing slide rail 6, and the grabbing assembly is used for grabbing and placing the film cloth in the table 2.

[0054] A connecting assembly 7 is located at the head of the table 2, and the connecting assembly 7 is used for fixedly connecting adjacent film sheets in a stacked manner.

[0055] The table 2 can slide along the table slide rail 3 in the application, the grabbing assembly can slide along the grabbing slide rail 6, the sliding of the grabbing assembly can place the grabbed film cloth on the table 2, after placing the film cloth each time, the table 2 will move a fixed distance along the table slide rail 3, and the position of the film cloth placed by the grabbing assembly is fixed, so that the adjacent film cloths can be distributed in staggered layers, and the distance of the adjacent film cloths in staggered layers is always kept the same; the connecting assembly 7 in the application fixes and connects the adjacent two layers of film cloths after the grabbing assembly places the film cloth each time, and reciprocates until the film cloths on the table 2 are stacked to a fixed number of layers, so that the stacked film cloths fixed together and distributed in staggered layers can be obtained. The application has simple structure and stacking method, and can realize the staggered stacking of the film cloths by means of the regular sliding of the table 2, and can integrate the stacking and fixing process of the film cloths in the film cloth stacking part 01, so that the film cloth stacking efficiency is significantly improved.

[0056] As a specific embodiment, the grabbing slide rail 6 is located above the support frame 1, and the grabbing slide rail 6 is parallel to the table slide rail 3. In the application, the sliding direction of the table 2 and the sliding direction of the grabbing assembly are the same, the sliding of the table 2 is to make the film cloth placed thereon staggered, and the grabbing assembly is used to grab and transmit the film cloth stacked in front of the film cloth stacking part 01 to the table 2 for placement.

[0057] As a specific embodiment, the grabbing assembly includes a translation plate 5 and at least one gripper 4 located on the translation plate 5; the grabbing slide rail 6 includes two parallel tracks, and the two ends of the translation plate 5 are located in the two tracks. Preferably, the gripper 4 is two, and the translation plate 5 is provided with a fixing hole for fixing the gripper 4, and the upper ends of the two grippers 4 are fixed in the fixing hole. The fixing hole in the translation plate 5 is multiple, and the position of the gripper 4 can be adjusted according to the size of the film cloth, and the two grippers 4 are used to grab the two ends of the film cloth and move it to the table 2 for placement.

[0058] The support frame 1 is provided with a connecting slide rail, and the connecting assembly 7 is located in the connecting slide rail, and the connecting slide rail is parallel to the table slide rail 3. The reason why the connecting slide rail is arranged in the application is to ensure that the connecting assembly 7 can move to the position above the film cloth for fixing when fixing the adjacent film cloths, and after fixing, the connecting assembly 7 exits the position of the film cloth, so that the placement of the upper film cloth is not affected.

[0059] The connecting assembly 7 in the application can be fixed or can slide along the connecting slide rail. If the action position of the connecting assembly 7 is just located at the position where the film cloth needs to be fixed and connected, the position where the film cloth needs to be fixed and connected is fixed after the table top 2 advances by a preset distance each time, at this time, the connecting assembly 7 can be fixed, and welding is directly performed after the film cloths are stacked. If the action position of the connecting assembly 7 blocks the placement position of the film cloth, the connecting assembly 7 can be arranged to slide along the connecting slide rail, and when the film cloths need to be fixed and connected, the connecting assembly 7 slides to the head of the overlapping position of the two layers of film cloths, and the connecting assembly 7 exits above the film cloths after the fixed connection is completed.

[0060] As a specific embodiment, the connecting assembly 7 is a welding machine for welding the adjacent film sheets stacked.

[0061] The connecting assembly 7 is a dispensing machine for dispensing and fixing the adjacent film sheets stacked. The dispensing machine is used for dispensing on the upper surface of the lower layer of film cloths, and when the upper layer of film cloths is misplaced on the upper surface of the lower layer of film cloths, the two are fixed and connected by glue.

[0062] The support frame 1 is provided with a pressing assembly for pressing the first layer of film cloths on the table top 2. The first layer of film cloths refers to the first layer of film cloths located on the upper surface of the table top 2. When the first layer of film cloths is placed on the table top 2, there is still a certain time before the next layer of film cloths arrives and is welded. If the first layer of film cloths slides during this period, the misalignment distance of the first layer of film cloths and the second layer of film cloths will not equal the moving distance of the table top 2, which will cause misalignment deviation. Therefore, after the first layer of film cloths is placed in position, the tail end of the first layer of film cloths is pressed on the table top 2 by the pressing assembly, and the pressing assembly continues to work in the subsequent stacking process. Other layers of film cloths located above the first layer of film cloths are fixed on the first layer of film cloths. When the first layer of film cloths is fixed, the position of the entire stacked film cloths is fixed.

[0063] The pressing assembly in the application can be a pressing cylinder.

[0064] The mechanism of the film cloth stacking part 01 in the application is described below by two specific examples:

[0065] As a specific embodiment, the working mechanism is as follows: the gripper 4 grabs the first layer of film cloths and moves to a preset position above the table top 2 along the grabbing slide rail 6, the gripper 4 places the first layer of film cloths on the table top 2, and returns to the initial position;

[0066] The pressing assembly works to press the tail end of the first layer of film cloths. The tail end here refers to the end away from the welding machine, and the welding machine is located at the head position of the first layer of film cloths.

[0067] The table 2 advances along the table slide rail 3 by a preset distance, where the advance refers to moving towards the position close to the welding machine; the preset distance is the distance of the film cloth misalignment;

[0068] The grabber 4 grabs the second layer of film cloth and moves along the grabbing slide rail 6 to a preset position above the table 2, and the grabber 4 places the second layer of film cloth on the table 2 and returns to the initial position;

[0069] The table 2 advances along the table slide rail 3 by a preset distance; at this time, the welding assembly of the welding machine is located at the position where the first layer of film cloth and the second layer of film cloth need to be welded, and the position where the second layer of film cloth overlaps with the third layer of film cloth is located outside the welding machine;

[0070] The welding machine welds the first layer of film cloth and the second layer of film cloth;

[0071] The above-mentioned table 2 advancing, grabbing and welding process is repeated until the film cloth is stacked to a specific number of layers.

[0072] As a specific embodiment, the working mechanism is as follows:

[0073] The grabber 4 grabs the first layer of film cloth and moves along the grabbing slide rail 6 to a preset position above the table 2, and the grabber 4 places the first layer of film cloth on the table 2 and returns to the initial position;

[0074] The pressing assembly works to press the tail end of the first layer of film cloth, where the tail end refers to the end away from the welding machine, and the dispensing machine is located at the head position of the first layer of film cloth;

[0075] The table 2 advances along the table slide rail 3 by a preset distance, where the advance refers to moving towards the position close to the dispensing machine; the preset distance is the distance of the film cloth misalignment; at this time, the dispensing machine moves along the connecting slide rail by a set distance to reach the position where the heads of the first layer of film cloth and the second layer of film cloth overlap, and dispenses glue on the first layer of film cloth, and after dispensing, the dispensing machine returns to the original position to avoid affecting the placement of the head of the subsequent second layer of film cloth;

[0076] The grabber 4 grabs the second layer of film cloth and moves along the grabbing slide rail 6 to a preset position above the table 2, and the grabber 4 places the second layer of film cloth on the table 2 and returns to the initial position; the second layer of film cloth is fixedly connected with the first layer of film cloth by glue;

[0077] The above-mentioned table 2 advancing, grabbing and dispensing process is repeated until the film cloth is stacked to a specific number of layers.

[0078] Please refer to the attached Figures 2-3The center tube feeding assembly 04 and the membrane sheet feeding assembly 02 in the application are respectively located on both sides of the winding station 03, and can simultaneously transmit the center tube 10 and the membrane sheet to the winding station 03; at the same time, the membrane sheet feeding assembly 02 in the application can complete the stacking of the membrane sheet during the feeding process, and the winding can be directly performed after the feeding is completed. The application has simple structure, high integration, can simultaneously realize the center tube 10 feeding, the membrane sheet feeding and the filter core winding process, reduces the setting of the process platform, and can effectively improve the filter core winding efficiency.

[0079] As a specific embodiment, the center tube feeding assembly 04 in the application includes a center tube storage cabin 13 and a center tube gripper 14. The center tube 10 is placed in the center tube storage cabin 13. The center tube gripper 14 grasps one center tube 10 in the center tube storage cabin 13 each time and transmits it to the fixing assembly for fixing.

[0080] As a specific embodiment, the membrane sheet feeding assembly 02 includes a membrane sheet gripper 20 and a membrane sheet table 21. The head of the bottom flow guide cloth is fixed on the center tube 10, and the tail is located on the membrane sheet table 21. The membrane sheet gripper 20 is used for grasping and placing the membrane sheet on the bottom flow guide cloth in a staggered manner.

[0081] Specifically, the membrane sheet gripper 20 is located in the membrane sheet slide rail, and the membrane sheet slide rail is located above the membrane sheet table 21. The membrane sheet gripper 20 moves along the membrane sheet slide rail and grasps the bottom flow guide cloth and the membrane sheet to the membrane sheet table 21 in turn. The length of the bottom flow guide cloth is relatively long. After the membrane sheet gripper 20 grasps the bottom flow guide cloth, the head of the bottom flow guide cloth is placed on the winding station. The fixing assembly on the winding station fixes the head of the bottom flow guide cloth and the center tube 10 together. Specifically, the fixing assembly can be a welding machine 22 or a dispensing machine and the like for fixing. The fixing of the center tube 10 and the bottom flow guide cloth can be performed before the center tube 10 is fixed on the fixing rod 11 or after the center tube 10 is fixed on the fixing rod 11. When the fixing of the center tube 10 and the bottom flow guide cloth is performed before the center tube 10 is fixed on the fixing rod 11, the center tube gripper 14 grasps the center tube 10 in the fixing assembly, the membrane sheet gripper 20 grasps the bottom flow guide cloth in the fixing assembly, and the fixing assembly fixes the head of the center tube 10 and the bottom flow guide cloth. Then, the center tube gripper 14 grasps the center tube 10 to be fixed between the two fixing rods 11. When the fixing of the center tube 10 and the bottom flow guide cloth is performed after the center tube 10 is fixed on the fixing rod 11, the fixing assembly is provided with a movable support. The movable support drives the fixing assembly to move to the center tube 10. At the same time, the membrane sheet gripper 20 grasps the bottom flow guide cloth to the center tube 10, and the fixing assembly fixes the head of the center tube 10 and the bottom flow guide cloth.

[0082] The length of the bottom flow guide cloth is relatively long. After the head of the bottom flow guide cloth is fixed to the center tube 10, the rear end extends to the membrane table 21. All subsequent membranes to be stacked need to be placed on the bottom flow guide cloth. The membrane gripper 20 places the membranes on the bottom flow guide cloth on the membrane table 21 in sequence. Each membrane is offset from the position of the previous membrane by a distance. The distance between adjacent membranes is equal. The distance between the second layer of membranes and the first layer of membranes is less than the distance between the first layer of membranes and the head of the bottom flow guide cloth. In order to ensure smooth winding, the distance between adjacent membranes is small, which can also ensure good filtering performance of the filter core after winding.

[0083] The present application can control the offset placement of the membranes on the bottom flow guide cloth by controlling the distance of each forward movement of the membrane gripper 20.

[0084] Further, in order to ensure that the position of the membrane does not shift or fall during winding, a dispensing machine can be provided on the side of the membrane table 21 to dispense and paste adjacent membranes, so that the position of the membrane remains relatively unchanged during the entire winding process.

[0085] The membrane of the present application includes N layers of membrane cloth, and adjacent membrane cloths are offset stacked. In the present application, the membrane cloths are offset stacked to form a membrane, and the membrane is offset stacked and then wound, which can better ensure that the final filter core has good filtering performance.

[0086] As a specific embodiment, when the fixing assembly is a welding machine 22, the membrane gripper 20 places the head of the bottom flow guide cloth on the winding station after grabbing the bottom flow guide cloth, and the welding machine 22 on the winding station fixes the head of the bottom flow guide cloth to the center tube 10. Specifically, the center tube gripper 14 grabs the center tube 10 in the fixing assembly, the membrane gripper 20 grabs the bottom flow guide cloth in the welding machine 22, and after the welding machine 22 fixes the head of the center tube 10 and the bottom flow guide cloth, the center tube gripper 14 grabs the center tube 10 between the two fixing rods 11 for fixation. After the bottom flow guide cloth and the center tube 10 are welded, in order to ensure that the subsequent membrane stacking does not affect the welding effect, the bottom flow guide cloth can be pre-wound, i.e., the bottom flow guide cloth is wound several times on the center tube 10 before the membrane stacking.

[0087] In order to ensure that the position of the membrane does not shift or fall during winding, a dispensing machine can be provided on the side of the membrane table 21 to dispense and paste adjacent membranes, so that the position of the membrane remains relatively unchanged during the entire winding process.

[0088] As another embodiment, when the fixing assembly is a dispensing machine, the film sheet gripper 20 places the head of the bottom guiding cloth on the winding station after grabbing the bottom guiding cloth, and the dispensing machine on the winding station fixes the head of the bottom guiding cloth and the center tube 10 together. Specifically, the dispensing machine is provided with a movable support, the movable support drives the dispensing machine to move to the center tube 10, at the same time, the film sheet gripper 20 grabs the bottom guiding cloth to the center tube 10, and the dispensing machine pastes the center tube 10 and the head of the bottom guiding cloth. After the bottom guiding cloth and the center tube 10 are pasted, in order to ensure that the subsequent film sheet stacking does not affect the pasting effect, the bottom guiding cloth can be pre-wound first, that is, the bottom guiding cloth is wound several times on the center tube 10, and then the film sheet stacking is performed.

[0089] Please refer to the accompanying drawings Figures 5-6 The winding assembly in the application comprises symmetrically distributed driving assemblies, and each driving assembly comprises:

[0090] The rotating support 35 is provided with a first gear 38 and a fixed rod 11 fixed at the center of the first gear 38; the axis lines of the fixed rods 11 in the two driving assemblies coincide; and the two fixed rods 11 are used for fixing the two ends of the center tube 10.

[0091] The rotating motor 33 is connected to the center of the second gear 39, and the second gear 39 and the first gear 38 are meshed and arranged side by side.

[0092] The application adopts double-side driving to drive the center tube 10 to rotate, the axis lines of the fixed rods 11 in the two driving assemblies coincide, the two ends of the center tube 10 are fixed by the fixing members in the two rotating supports 35, and the corresponding rotating motors 33 of the fixed rods 11 drive the second gears 39, the second gears 39 and the fixing members and the center tube to rotate, so that the two ends of the center tube 10 are synchronously driven by different rotating motors 33, and it is ensured that the two ends of the center tube 10 are simultaneously subjected to the rotating driving force during the winding process; the application adopts the double-side driving assembly, so that the center tube 10 is subjected to double-side force during the winding process, the uniform consistency of the winding tension is ensured, and the performance of the filter element is improved.

[0093] The driving assemblies in the application are symmetrically arranged, and the structures of the two driving assemblies are the same. In order to facilitate description, the structure of only one of the driving assemblies is described in detail below, and the other one has the same structure.

[0094] As a specific example, the fixed rod 11 in the present application is a tension rod, one end of the tension rod is fixedly connected with the rotating support 35, and the other end is provided with an expansion piece for fixing or loosening the inner diameter of the center pipe 10. The expansion piece is connected with the output end of the tension cylinder 32, and the tension cylinder 32 is used to control the expansion or retraction of the expansion piece. When the tension cylinder 32 is extended, the expansion piece connected with the tension cylinder 32 is expanded, at this time, the expansion piece abuts against the inner diameter of the center pipe 10, and is used to fix the center pipe 10. When the expansion piece is in the retracted state, the outer diameter of the expansion piece is smaller than the inner diameter of the center pipe 10, so that the center pipe 10 can be conveniently taken out of the tension rod, or the tension rod can be conveniently placed inside the center pipe 10.

[0095] In actual application, the length of the center pipe 10 is greater than the length of the winding part, and the fixed parts without winding film cloth are arranged at both ends of the center pipe 10. The fixing holes can be arranged in the fixed parts, and the fixing pins in the expansion piece of the tension rod can pass out of the fixing holes when the expansion piece is in the expanded state, so as to fix the center pipe 10 and ensure that the rotating motor 33 can drive the tension rod and the center pipe 10 to rotate.

[0096] The tension cylinder 32 in the present application is fixed in the rotating support 35, so as to better fix or loosen the tension rod.

[0097] As a specific example, the tension cylinder 32 in the present application is fixed in the rotating support 35, so as to better fix or loosen the tension rod.

[0098] The rotating support 35 in the present application is arranged in the base 34, and the base 34 is fixed in the workbench. The base 34 is provided with a support sliding rail, and the rotating support 35 is located in the support sliding rail. The rear end of the rotating support 35 is fixedly connected with the output end of the advancing cylinder 31, the advancing cylinder 31 is fixed in the base 34, and the advancing cylinder 31 can drive the rotating support 35 to move along the support sliding rail towards the direction close to or away from the other rotating support 35. The advancing cylinder 31 is two, corresponding to two rotating supports 35, and is used to advance the rotating support 35 from both sides, so as to adjust the distance between the two fixed rods 11.

[0099] When the size of the center pipe 10 becomes larger or smaller, the distance between the two fixed parts can be adjusted by the advancing cylinder 31 to drive the rotating support 35. The advancing cylinder 31 is extended to different degrees, so as to ensure that the two fixed parts have different distances.

[0100] When the center tube 10 needs to be fixed on the rotating support 35, the gap between the two fixing rods 11 can be first enlarged by the pushing cylinder 31, so that one end of the center tube 10 is fixed on one of the fixing rods 11, and then the gap between the two fixing rods 11 is reduced by the pushing cylinder 31, so that both ends of the center tube 10 are fixed on the fixing rods 11 respectively.

[0101] In the present application, the pushing cylinder 31 is fixed in the base 34 and remains stationary. The rotating motor 33 and the tension cylinder 32 are fixed in the rotating support 35, which is fixed in the support slide rail, and the extension direction of the support slide rail is parallel to the axial direction of the center tube 10.

The pushing cylinder 31 can drive the base 34 to move along the base slide rail towards the direction of approaching or moving away from the other base 34.

[0104] When the size of the center tube 10 becomes larger or smaller, the base 34 can be pushed by the pushing cylinder 31 to adjust the distance between the two fixing members. Different degrees of extension of the pushing cylinder 31 can ensure that the two fixing members have different spacings.

[0105] When the center tube 10 needs to be fixed on the rotating support 35, the gap between the two fixing rods 11 can be first enlarged by the pushing cylinder 31, so that one end of the center tube 10 is fixed on one of the fixing rods 11, and then the gap between the two fixing rods 11 is reduced by the pushing cylinder 31, so that both ends of the center tube 10 are fixed on the fixing rods 11 respectively.

[0106] The advancing cylinder 31 in the application is fixed in the workbench and remains stationary. The rotating motor 33, the tensioning cylinder 32 and the rotating support 35 are fixed in the base 34 and remain stationary relative to the base 34, and the base 34 is fixed in the base sliding rail, and the extension direction of the base sliding rail is parallel to the axial direction of the center tube 10. Under the action of the advancing cylinder 31, the base 34 drives the rotating support 35, the rotating motor 33 and the tensioning cylinder 32 above it to move towards the direction of approaching or moving away from the other side base 34.
