Description

Technical Field

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

[0002] like Figure 1 As shown, an industrial RO membrane filter element product in the prior art, the filter element 5 includes a central tube 51 and a filter membrane layer 52 wrapped around the outside of the central tube 51, and the filter membrane layer 52 is formed by winding an RO membrane around the outside of the central tube 51. However, after the RO membrane is wrapped on 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, which easily leads to unevenness at both ends of the filter element 5, which not only affects the appearance, but also causes burrs at both ends of the filter element 5. In addition, the length of the filter element 5 needs to be limited in production, so the two ends of the filter element 5 need to be cut, and the cut waste 50 is 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 prior art are usually relatively complicated, and the waste cutting and stripping effects are not ideal. In addition, the positioning effect of the filter element 5 during cutting is poor, which makes the filter element 5 prone to accidental rotation during the cutting process, resulting in poor cutting effect, which urgently needs to be improved. Summary of the Invention

[0006] 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 guidance of the external support guide matching structure, the plurality of tensioning members can extend outward from the corresponding mounting holes relative to the plug-in sleeve to an expanded state, so that the plurality of tensioning members and the inner wall of the central tube are pressed against each other; under the guidance of the internal retraction guide matching structure, the plurality of tensioning members can retract into the corresponding mounting holes relative to the plug-in sleeve to a retracted state, so that the plurality of tensioning members and the central tube are separated from each other.

[0007] The trimming mechanism cooperates with the corresponding rotation positioning mechanism to enable the cutting blade to cut circumferentially at the end of the filter element to form a slit; the stripping mechanism includes a stripping plate, which cooperates with the corresponding rotation positioning mechanism to drive the stripping plate to insert into the slit and strip the waste material at the end of the filter element along its axial direction.

During the process of inserting the plug-in sleeve into the center tube, the external support guide matching structure drives a plurality of tensioning members to extend outward to the expanded state, so that the outer wall of the tensioning member is pressed against the inner wall of the center tube; the trimming mechanism drives the cutting blade to rotate at high speed, and at the same time, the rotary drive device drives the filter element to rotate synchronously through the tensioning positioning structure, and uses the cutting blade to cut circumferentially at the end of the filter element to form a slit, and then the guide The driving device drives the plug-in sleeve to be withdrawn from the central tube. During the withdrawal process, the guiding effect of the retracted guide matching structure is utilized to retract the plurality of tensioning members radially inward relative to the plug-in sleeve to a storage state, and the tensioning members and the central tube are separated from each other. Afterwards, the transfer mechanism is utilized to transport the cut filter element as a whole to the stripping mechanism, so that the central tube is aligned with the rotary positioning mechanism on one side of the stripping mechanism, and the rotary positioning mechanism is utilized to position the filter element at the processing position of the stripping mechanism. The stripping plate is driven by the stripping mechanism to be inserted into the corresponding slit, and then the stripping plate is driven to remove the waste material at the end of the filter element axially outward. Peeling, in the process of peeling the waste outward, the rotary drive device is used to drive the plug-in sleeve to drive the filter element to rotate synchronously, so that the rotating filter element and the stripping of the waste are carried out at the same time, which is conducive to separating the waste from the end of the filter element more completely and smoothly; the present invention uses the tensioning positioning structure, the rotary drive device and the guide drive device to cooperate with each other, so that when the plug-in sleeve is inserted into the central tube, the tensioning member can be driven to open outward and press against the inner wall of the central tube through the external support guide matching structure, so that the trimming mechanism and the stripping mechanism can always ensure that the tensioning member is in a state of continuous cutting and stripping of the waste material in the filter element. The filter element and the plug-in sleeve are kept in a mutually fixed state, which effectively prevents the filter element from slipping relative to the plug-in sleeve during the cutting and stripping process, thereby ensuring the concentricity of the filter element when it is driven to rotate by the rotary drive device, and improving the flatness of both ends of the filter element after the trimming mechanism has cut the waste. In addition, by rotating the filter element and stripping the waste material synchronously, it can effectively prevent the waste material from getting stuck during stripping, thereby improving the efficiency of the waste stripping of this equipment, and has the effects of improving the positioning ability and concentricity of the filter element during rotation, the flatness of the filter element end face after the waste material is cut off, and improving the smoothness of the waste stripping.

The stripping plate 14 is vertically arranged at the output end of the corresponding linear adjustment module 13. The lifting cylinder 11 can drive the mounting plate 12 to drive the linear adjustment module 13 to move up and down. The linear adjustment modules 13 on both sides are used to adjust the distance between the stripping plates 14 on both sides. The lifting cylinder 11 can drive the mounting plate 12 to move up and down, and then the mounting plate 12 drives the stripping plates 14 at the output end of the linear adjustment module 13 to move up and down synchronously, so that the stripping plates 14 are inserted into the slit 5a of the filter element 5. At the same time, the linear adjustment module 13 can drive the corresponding stripping plates 14 to move along the horizontal direction of the mounting plate 12. Not only can the waste 50 be stripped from the side end of the filter element 5 by the stripping plate 14, but the distance between the stripping plates 14 on both sides can also be adjusted to adapt to the processing requirements of filter elements 5 of different lengths.

[0050] The basic working principle of the present invention is as follows: a transfer mechanism 2 is set between the trimming mechanism 3 and the peeling mechanism 1, and a set of rotation positioning mechanisms 4 are respectively provided on the side of the trimming mechanism 3 and the peeling mechanism 1, wherein the rotation positioning mechanism 4 includes a tensioning positioning structure 41, a rotation drive device 42 and a guide drive device 43, the tensioning positioning structure 41 includes a plug sleeve 411, and a plurality of tensioning members 412 arranged at intervals along the circumferential direction on the side wall of the plug sleeve 411, the rotation drive device 42 can drive the plug sleeve 411 to rotate, and the guide drive device 43 is connected to the guide structure through the guide structure. The tensioning member 412 guides and cooperates; during processing, the filter element 5 to be processed is first installed on the rotation positioning mechanism 4 aligned with the trimming mechanism 3, and the guide driving device 43 is used to drive the plug sleeve 411 to align and insert into the center tube 51 of the filter element 5. In the process of inserting the plug sleeve 411 into the center tube 51, the external support guide cooperation structure drives the tensioning members 412 to extend outward to the expanded state, so that the outer wall of the tensioning member 412 is pressed against the inner wall of the center tube 51; the trimming mechanism 3 drives the cutting blade 311 to rotate at a high speed, and at the same time, the rotation driving device 42 drives the tensioning member 412 ...1 to rotate at a high speed, and at the same time, the rotation driving device 42 drives the tensioning member 411 to rotate at a high speed, and at the same time, the rotation driving device 42 drives the tensioning member 412 to rotate at a high speed, and at the same time, the rotation driving device 42 drives the tensioning member 411 to rotate at a high speed, and at the same time, the rotation driving device 42 drives the tension The tight positioning structure 41 drives the filter element 5 to rotate synchronously, and uses the cutting blade 311 to cut the end of the filter element 5 in an annular direction to form a slit 5a. Then, the guide drive device 43 drives the plug-in sleeve 411 to be withdrawn from the central tube 51. During the withdrawal process, the guiding effect of the retracting guide matching structure is used to make the plurality of tensioning members 412 retract radially inward relative to the plug-in sleeve 411 to the storage state, and the tensioning members 412 and the central tube 51 are separated from each other; then, the transfer mechanism 2 is used to transport the cut filter element 5 as a whole to the stripping mechanism 1, so that the central tube 51 and the stripping mechanism 1 are separated. The rotary positioning mechanism 4 on one side is aligned, and the filter element 5 is positioned at the processing position of the stripping mechanism 1 by using the rotary positioning mechanism 4. 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. During the process of stripping the waste material 50 outward, the rotary driving device 42 is used to drive the plug sleeve 411 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 simultaneously, which is conducive to separating the waste material 50 from the end of the filter element 5 more completely and smoothly.The present invention utilizes the cooperation of the tensioning and positioning structure 41, the rotation driving device 42 and the guide driving device 43, so that when the plug-in sleeve 411 is inserted into the central tube 51, the tensioning member 412 can be driven to open outward and press against the inner wall of the central tube 51 through the external support and guide cooperation structure, so that when the trimming mechanism 3 and the stripping mechanism 1 cut and strip the waste material 50 of the filter element 5 in the corresponding circumferential direction, the tensioning member 412 can always ensure that the filter element 5 and the plug-in sleeve 411 are kept in rotation with each other, effectively preventing the filter element 5 from being rotated during the cutting and stripping process. The slipping of the plug sleeve 411 ensures the concentricity of the filter element 5 when driven by the rotary drive device 42, and improves the flatness of the ends of the filter element 5 after the trimming mechanism 3 has cut the waste material 50. In addition, by rotating the filter element 5 and stripping the waste material 50 synchronously, it can effectively prevent the waste material 50 from getting stuck during stripping, thereby improving the efficiency of the waste material 50 stripping device of this device. It has the effects of improving the positioning ability and concentricity of the filter element during rotation, improving the flatness of the filter element end surface after the waste material is cut off, and improving the smoothness of the waste material stripping.
