Description

Technical Field

[0001] The present invention relates to the technical field of filter element processing, and in particular to processing equipment and a processing method of an industrial RO membrane filter element. Background Art

[0002] like Figure 1 As shown, it is an industrial RO membrane filter element product in the prior art, the filter element 5 includes a central tube 51, a filter membrane layer 52 wrapped around the outside of the central tube 51, and end caps 6 welded and fixed to both ends of the central tube 51, wherein the filter membrane layer 52 is formed by winding the RO membrane around the outside of the central tube 51, and the end caps 6 are inserted and positioned with the ends of the central tube 51 through positioning holes 6a, and then the end caps 6 are welded and fixed to the central tube 51 by welding. However, after the RO membrane is wrapped around the central tube 51, due to the accuracy problem of the wrapping equipment, the adjacent wrapped layers of the filter membrane layer 52 will not be completely aligned, and the two ends of the filter element 5 are prone to unevenness, which not only affects the appearance, but also causes burrs to appear on both ends of the filter element 5. In addition, the length of the filter element 5 needs to be limited in production, so it is necessary to The two ends of the filter element 5 product need to be cut, and the cut waste materials need to be removed from both ends of the filter element 5. At the same time, the flatness of the two ends of the filter element 5 after cutting needs to be ensured. However, the filter element cutting equipment and waste stripping equipment in the existing technology are usually more complicated, and the waste cutting and stripping effects are not ideal. In addition, in the process of processing and producing the filter element, the factory also involves the air tightness detection process of the central tube 51, the welding process of installing and welding the end cover 6 to the end of the central tube 51, and the labeling process of sticking labels on the outer wall of the filter element 5. The various processes need to be better connected to improve the processing efficiency of the filter element. In order to meet the above requirements, the existing filter element processing and production equipment usually has insufficient connection between the various processes and requires manual intervention, resulting in insufficient processing efficiency of the filter element 5, which urgently needs to be improved. Summary of the Invention

[0003] The purpose of the present invention is to provide an industrial RO membrane filter element processing equipment and a processing method thereof, which has the effects of improving the efficiency of waste stripping, improving the flatness of the filter element end surface after the waste is cut off, preventing the waste from getting stuck during stripping, and enabling multi-station continuous processing to improve processing efficiency.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A processing equipment for industrial RO membrane filter element, comprising:

[0005] Rotary positioning mechanism, used to position the filter element and drive it to rotate;

[0006] A cutting mechanism, comprising a cutting blade, the cutting mechanism cooperating with the rotation and positioning mechanism to drive the cutting blade to cut circumferentially at the end of the filter element to form a slit;

[0007] A stripping mechanism, comprising a stripping plate, which cooperates with the rotation positioning mechanism to drive the stripping plate to be inserted into the corresponding slit and to strip the waste material at the end of the filter element along the axial direction;

[0008] Air tightness testing mechanism, used to test the air tightness of the filter element;

[0009] An end cap feeding mechanism and an end cap installation mechanism, wherein the end cap installation mechanism includes a pressing device and a welding device. The end cap feeding mechanism cooperates with the pressing device to feed the end cap and press it onto the end of the central tube. The welding device is used to weld and fix the end cap to the filter element;

[0010] A labeling mechanism, used to stick labels on the outer wall of the filter element;

[0011] The transfer mechanism drives the filter element to be transported in sequence among the cutting mechanism, the stripping mechanism, the air tightness testing mechanism, the end cap installation mechanism and the labeling mechanism.

[0012] By adopting the above technical solution, the filter element to be processed is installed on the rotary positioning mechanism aligned with the cutting mechanism, the cutting mechanism drives the cutting blade to rotate at high speed, and at the same time the rotary positioning mechanism drives the filter element to rotate, and the cutting blade is used to cut the end of the filter element in an annular direction to form a slit, and then the rotary positioning mechanism releases the positioning of the filter element, and then the transfer mechanism is used to transport the filter element cut by the cutting mechanism as a whole to the stripping mechanism, so that the inner cavity of the central tube is aligned with the rotary positioning mechanism on one side of the stripping mechanism, and at this time the rotary positioning mechanism on the side of the stripping mechanism is used to position the filter element on the stripping mechanism. The stripping mechanism drives the stripping plate to be inserted into the corresponding slit, and then drives the stripping plate to strip the waste material at the end of the filter element axially outward. In the process of stripping the waste material outward, the rotary positioning mechanism is used to drive the filter element to rotate synchronously, so that the filter element is rotated and the waste material is stripped at the same time, so that the waste material can be separated from the end of the filter element more smoothly and completely. After that, the transfer mechanism transfers the filter element where the waste material stripping of the stripping mechanism has been completed to the position of the air tightness detection mechanism, and uses the air tightness detection mechanism to inflate the center tube of the filter element, and then uses the pressure holding test to detect the air tightness of the filter element. When the air tightness test is qualified, it is transported to the next station through the transfer mechanism. When the air tightness test is unqualified, the filter element is screened out, and the end cap is loaded through the cooperation of the end cap loading mechanism and the pressing device, and is pressed and installed to the end of the center tube that has passed the air tightness test. The end cap is then welded and fixed to the end of the center tube by the welding device. The transfer mechanism transfers the filter element with the welded end cap to the labeling mechanism, and the labeling mechanism is used to stick the label on the outer wall of the filter element. Finally, the product is discharged. It also has multiple stations for cutting, waste stripping, air tightness testing, end cap installation and label sticking. The continuous processing feature is conducive to industrial continuous processing and production; in addition, the present invention utilizes the rotation positioning mechanism and the cutting mechanism to cooperate with each other, so that the filter element can be cut in an annular direction while rotating, thereby improving the efficiency of waste cutting and the cutting flatness of the filter element end. In addition, the rotating filter element and the waste stripping are also carried out synchronously, which can effectively prevent the waste from getting stuck during stripping, and has the effects of improving the efficiency of waste stripping, improving the flatness of the filter element end face after the waste is cut off, preventing the waste from getting stuck during stripping, and enabling multi-station continuous processing to improve processing efficiency.

[0014] By adopting the above technical solution, when the filter element after the waste stripping is transported to the position of the air tightness detection mechanism by the transfer mechanism, the piston rod of the telescopic cylinder extends, driving the plug-in part to be inserted into the corresponding central tube, and the sealing between the plug-in part and the central tube is achieved through the corresponding sealing ring. Thereafter, air is inflated from the inflation hole through the external pressurizing equipment, and the gas in the inflation hole is pumped into the central tube through the plug-in hole. Then, the air tightness of the central tube is recorded through the pressure maintaining test. The present invention can adapt to central tubes with different inner hole diameters for plugging and air sealing by arranging sealing rings on the outer wall of the plug-in part and the inner wall of the plug-in hole. The central tube with a larger diameter can be mounted on the outside of the plug-in part for fixation, while the central tube with a smaller diameter can be directly inserted into the plug-in hole for fixation.

[0015] The present invention is further configured as follows: the end cap feeding mechanism includes a feeding conveyor line, a feeding translation module, a feeding lifting module provided at the output end of the feeding translation module, and a flip clamping module provided at the output end of the feeding lifting module;

[0016] The pressing device includes a pressing cylinder and a positioning column arranged at the output end of the pressing cylinder. The end of the positioning column is coaxially provided with a plurality of positioning steps, and the diameters of the plurality of positioning steps increase in a step-like manner from the inside to the outside.

[0017] By adopting the above technical solution, the feeding translation module and the feeding lifting module cooperate with each other to drive the flip clamping module to clamp the end cap on the feeding conveyor line, and transport the clamped end cap to a position where the pressing device is aligned. Then, the flip clamping module flips 90° to align the end cap with the positioning column at the output end of the pressing cylinder. The pressing cylinder drives the positioning column to extend and insert into the positioning hole of the end cap. After that, the end cap feeding mechanism is reset, and the piston rod of the pressing cylinder continues to extend and drives the end cap to move toward the filter element through the positioning column until the side end of the center tube is inserted into the positioning hole of the end cap to realize the press installation of the end cap, and then the welding device is used to realize the welding fixation between the end cap and the center tube.

[0018] The present invention is further configured as follows: the end cover installation mechanism also includes a work station switching module, which can drive the pressing device or welding device to align the end of the filter element for processing, and the work station switching module includes a work station switching cylinder and a sliding seat fixed to the output end of the work station switching cylinder, and the pressing device and welding device are arranged on the sliding seat.

[0019] By adopting the above technical solution, the station switching cylinder drives the sliding seat to move horizontally, so that the pressing device and the welding device are switched correspondingly at the processing position of the filter element, which has the effect of making the station switching method more direct and simple, and the station switching position more precise.

[0020] The present invention is further configured as follows: the rotational positioning mechanism includes a tensioning positioning structure, a rotational drive device, and a guide drive device; the tensioning positioning structure includes a guide drive member, a plug sleeve, and a plurality of tensioning members; the rotational drive device can drive the plug sleeve to rotate; the plug sleeve is axially provided with an accommodating cavity, and a plurality of mounting holes communicating with the accommodating cavity are circumferentially spaced apart on a side wall of the plug sleeve; an end portion of the guide drive member is movably inserted into the accommodating cavity, and a plurality of the tensioning members are slidably provided in corresponding mounting holes;

[0021] An external support guide matching structure and an internal retraction guide matching structure are provided between the guide drive device and the tensioning member. Under the guiding action of the external support guide matching structure, several of the tensioning members can extend outward from the corresponding mounting holes relative to the plug-in sleeve to an expanded state, or retract into the corresponding mounting holes relative to the plug-in sleeve to a retracted state.

[0022] By adopting the above technical solution, when the plug-in sleeve is inserted into the center tube of the filter element, the guide driving component is pushed into the accommodating cavity. Under the guiding action of the external support guide matching structure, several tensioning parts extend outward from the mounting hole to the expanded state, so that the outer walls of multiple tensioning parts are pressed against the center tube of the filter element, thereby realizing the positioning and stopping of the filter element, which can effectively prevent the filter element from accidentally rotating during processing. When the filter element is processed in the corresponding work station, the guide driving component is pulled to move in the withdrawal direction in the accommodating cavity. Under the guiding action of the inward retracting guide matching structure, several tensioning parts are pulled back to the storage state in the mounting hole, thereby releasing the external support clamping effect of the tensioning parts on the center tube of the filter element, so that the tensioning parts and the filter element are separated from each other. In this way, the invention can utilize the tensioning positioning structure to fix or release the filter element, which has the effects of efficient and stable filter element positioning and faster conversion between fixing the filter element and releasing the filter element.

[0023] The present invention is further configured as follows: the guide drive device includes a first linear drive module, a second linear drive module, and a guide drive component arranged at the output end of the second linear drive module; the second linear drive module is fixed to the output end of the first linear drive module; the external support guide matching structure and the internal retracted guide matching structure are arranged between the guide drive component and the corresponding tensioning member.

[0024] By adopting the above technical solution, the first linear drive module can drive the second linear drive module to drive the guide drive component to translate as a whole, so that the plug-in sleeve is inserted into the inner cavity of the central tube or withdrawn from the inner cavity of the central tube. The second linear drive module can drive the guide drive component to move axially in the accommodating cavity, and drive the tensioning member to slide radially along the plug-in sleeve in the mounting hole through the external support guide matching structure and the internal retraction guide matching structure, thereby switching several tensioning members between the expanded state and the stored state.

[0025] The present invention is further configured as follows: the guide drive component includes a central drive rod, a guide sleeve and a guide cap, the guide sleeve is coaxially fixed to the outside of the central drive rod, the guide cap is coaxially fixed to the end of the central drive rod, the external support guide matching structure is arranged between the outer wall of the guide sleeve and the corresponding tensioning member, and the external support guide matching structure includes at least one external support guide inclined surface arranged on the guide sleeve and / or the tensioning member, the inward retracted guide matching structure is arranged between the inner wall of the guide cap and the corresponding tensioning member, and the inward retracted guide matching structure includes at least one inward retracted guide inclined surface arranged on the guide cap and / or the tensioning member.

[0026] By adopting the above technical solution, the rotary drive device can drive the plug-in sleeve to rotate, and the guide drive device can drive the central drive rod to drive the guide sleeve and the guide cap to slide axially in the accommodating cavity. When the driving end of the central drive rod extends into the accommodating cavity, under the guiding action of the external support guide matching structure, a number of tensioning parts extend outward from the corresponding mounting holes and press against the inner cavity of the central tube. When the central drive rod is pulled out of the accommodating cavity, under the guiding action of the inward retraction guide matching structure, a number of tensioning parts retract into the corresponding mounting holes and separate from the inner cavity of the central tube.

[0028] The present invention is further configured as follows: the transfer mechanism includes a lifting seat, a lifting drive device, a translation drive device and a plurality of support frames, wherein the plurality of support frames are symmetrically arranged on the lifting seat, the lifting drive device can drive the lifting seat to move up and down, and the translation drive device can drive the lifting seat to move horizontally; the support frame includes two mounting brackets arranged in a V shape and a smooth sleeve fixed on the corresponding mounting bracket.

[0029] By adopting the above technical solution, the translation drive device can drive the lifting seat to translate between the cutting mechanism and the peeling mechanism, and at the same time, the lifting drive device can be used to drive the lifting seat to move up and down, so that the support frame on the lifting seat carries the filter element to rise and fall synchronously. In addition, the support frame is set to a V shape, which can effectively improve the support stability and anti-shake performance of the support frame for the filter element. At the same time, the smooth contact surface of the smooth sleeve can prevent the outer surface of the filter element from being scratched.

The cutting mechanism 3 drives the cutting blade 311 to rotate at high speed. At the same time, the rotary positioning mechanism 4 drives the filter element 5 to rotate, and the cutting blade 311 is used to cut circumferentially at the end of the filter element 5 to form a slit 5a. Then, the rotary positioning mechanism 4 releases the positioning of the filter element 5.

At this time, the rotary positioning mechanism 4 on the side of the stripping mechanism 1 is used to position the filter element 5 in the processing position of the stripping mechanism 1, and the stripping plate 14 is driven by the stripping mechanism 1 to be inserted into the corresponding slit 5a, and then the stripping plate 14 is driven to strip the waste material 50 at the end of the filter element 5 axially outward. In the process of stripping the waste material 50 outward, the rotary positioning mechanism 4 is used to drive the filter element 5 to rotate synchronously, so that the rotation of the filter element 5 and the stripping of the waste material 50 are carried out at the same time, so that the waste material 50 can be separated from the end of the filter element 5 more smoothly and completely. The filter element 5 after the stripping of the waste material 50 from the mechanism 1 is transported to the position of the air tightness detection mechanism 7, and the central tube 51 of the filter element 5 is inflated by the air tightness detection mechanism 7, and then the air tightness of the filter element 5 is tested by the pressure holding test. When the air tightness test is qualified, it is transported to the next station through the transport mechanism 2. When the air tightness test is unqualified, the filter element 5 is screened out, and the end cap 6 is loaded by the end cap feeding mechanism 8 and the pressing device 91, and is pressed and installed to the end of the central tube 51 that has passed the air tightness test, and then the end cap 6 is welded and fixed to the end of the central tube 51 by the welding device 92. The transport mechanism 2 transports the filter element 5 with the end cap 6 welded to the labeling mechanism 10, and the labeling mechanism 10 is used to stick the label on the outer wall of the filter element 5 , and finally the product is discharged, and at the same time it has the multi-station continuous processing characteristics of cutting, waste stripping, airtightness detection, end cover installation and label pasting, which is conducive to industrial continuous processing and production; in addition, the present invention utilizes the rotary positioning mechanism 4 and the cutting mechanism 3 to cooperate with each other, so that the filter element 5 is circumferentially cut while rotating, thereby improving the efficiency of cutting the waste 50 and the cutting flatness of the end of the filter element 5, and the rotating filter element 5 and the waste 50 stripping are also carried out synchronously, which can effectively prevent the waste 50 from getting stuck when being stripped, and has the effects of improving the efficiency of waste stripping, improving the flatness of the filter element end face after the waste is cut off, preventing the waste from getting stuck when being stripped, and enabling multi-station continuous processing to improve processing efficiency.

During the process of stripping the waste material outward, the rotary drive device drives the plug-in sleeve to drive the filter element to rotate synchronously, so that the filter element is rotated and the waste material is stripped at the same time, so that the waste material can be separated from the end of the filter element more smoothly and completely;

[0074] S4: Air tightness test: The transfer mechanism is used to transfer the filter element after the waste stripping of the stripping mechanism to the air tightness test mechanism.

6. A method for processing an industrial RO membrane filter element according to any one of claims 1 to 5, characterized in that: The following steps are involved: S1: Filter element loading and trimming: The filter element to be processed is mounted on the rotary positioning mechanism aligned with the cutting mechanism. The cutting mechanism drives the cutting blade to rotate at high speed, while the rotary positioning mechanism drives the filter element to rotate. The cutting blade is used to cut the end of the filter element in a circumferential direction to form a slit. S2: Release and transfer: The rotary positioning mechanism releases the positioning of the filter element, and then the transfer mechanism transfers the filter element cut by the cutting mechanism to the stripping mechanism as a whole, so that the inner cavity of the central tube is aligned with the rotary positioning mechanism on one side of the stripping mechanism; S3: Positioning and stripping: The filter element is positioned at the processing position of the stripping mechanism using the rotary positioning mechanism on the side of the stripping mechanism. The stripping mechanism drives the stripping plate to be inserted into the corresponding slit, and then drives the stripping plate to strip the waste material at the end of the filter element axially outward. During the process of stripping the waste material outward, the rotary drive device drives the plug-in sleeve to drive the filter element to rotate synchronously, so that the filter element is rotated and the waste material is stripped at the same time, so that the waste material can be separated from the end of the filter element more smoothly and completely; S4: Air tightness test: The transfer mechanism is used to transfer the filter element after the waste stripping of the stripping mechanism to the air tightness test mechanism. The central tube of the filter element is inflated by the air tightness test mechanism, and then the air tightness of the filter element is tested by a pressure holding test. If the air tightness test is qualified, it is transported to the next station through the transfer mechanism. If the air tightness test is unqualified, the filter element is screened out; S5: End cap loading and installation: The end cap is loaded through the cooperation of the end cap loading mechanism and the pressing device, and is pressed and installed to the end of the center tube; S6: End cover welding: Use a welding device to weld and fix the end cover to the end of the central tube; S7: Label pasting: The transfer mechanism transfers the filter element with the end cap welded to the labeling mechanism, and uses the labeling mechanism to paste the label on the outer wall of the filter element; S8: Product discharge.
