Technical Field

The cylindrical filter element generally includes a cylindrical skeleton, a carbon fiber cylinder arranged on the outer periphery of the cylindrical skeleton, and a non - woven filter membrane wrapped outside the carbon fiber cylinder. In the related art, in order to obtain better filtration effect, refer to Figure 1 , first, one side edge of the first filter membrane 12 made of non - woven fabric is hot - press welded on the cylindrical skeleton 11, then the first filter membrane 12 is driven to wind around the outer periphery of the cylindrical skeleton 11 for at least one circle, then a certain length of the second filter membrane 13 made of carbon fiber material and the above - mentioned first filter membrane 12 are stacked together and wound around the axis of the cylindrical skeleton 11 for multiple circles until the second filter membrane 13 is completely wound on the cylindrical skeleton 11, and then after continuing to wind a section of the first filter membrane 12, the other side edge of the first filter membrane 12 is hot - press welded on its own surface, so as to form a cylindrical filter element that wraps both the first filter membrane 12 and the second filter membrane 13 inside to form a multi - layer filtration structure.

[0029] See Figures 1 to 4, A filter material winding and welding device for a filter element according to an embodiment of the present utility model includes: a machine base 100, a rotary drive mechanism 200 disposed on the machine base 100 for detachably mounting a cylindrical skeleton 11 and driving the cylindrical skeleton 11 to rotate around its axis; a membrane material supply device 300 disposed on the machine base 100, on one side of the rotary drive mechanism 200, capable of conveying a first filter membrane 12 made of non-woven fabric and a second filter membrane 13 made of carbon fiber to the outer peripheral side of the cylindrical skeleton 11; a welding device 400 movably disposed on the machine base 100 for thermally pressing and welding the two side edges of the first filter membrane 12 respectively; a displacement drive mechanism 500 for driving the rotary drive mechanism 200 and the membrane material supply device 300 to move relatively along the axial direction perpendicular to the cylindrical skeleton 11 to separate the first filter membrane 12 from the filter element 10.

[0030] When manufacturing the filter element 10, first install the cylindrical skeleton 11 on the rotary drive mechanism 200, convey the first filter membrane 12 to the outer peripheral side of the cylindrical skeleton 11 by the membrane material supply device 300, use the welding device 400 to weld and fix one side edge of the first filter membrane 12 on the cylindrical skeleton 11, drive the first filter membrane 12 to wind around the cylindrical skeleton 11 for at least one circle by the rotary drive mechanism 200, then stack a second filter membrane 13 with a preset size on the unwound first filter membrane 12, drive the first filter membrane 12 and the second filter membrane 13 to wind together by the rotary drive mechanism 200 until the second filter membrane 13 is completely wrapped by the cylindrical skeleton 11 and then the first filter membrane 12 continues to wrap the second filter membrane 13 inside, then the welding device 400 welds and fixes the other side edge of the first filter membrane 12 on the surface of the first filter membrane 12, and finally use the displacement drive mechanism 500 to drive the first filter membrane 12 to break at the welding line position, thereby improving the automation degree of filter material winding and welding, enhancing the processing efficiency, and making the produced filter element 10 have stable and reliable quality.

[0031] See Figures 2 to 4In some embodiments of the utility model, the rotating drive mechanism 200 includes a rotating shaft 210 rotatably provided on the machine base 100 and a motor 220 driving the rotating shaft 210 to rotate, the rotating shaft 210 can extend from one end of the cylindrical skeleton 11 and tightly match the inner diameter channel of the cylindrical skeleton 11, a movable seat 600 is provided on the machine base 100, and a limiting shaft 610 is rotatably provided on the movable seat 600, and the movable seat 600 is connected to a driving component 620 that drives the limiting shaft 610 to move to be coaxial with the rotating shaft 210 and abut against the other end of the cylindrical skeleton 11. It is understandable that the cylindrical frame 11 is inserted from the end of the rotating shaft 210 and is tightly matched with the rotating shaft 210, and then the driving assembly 620 drives the movable seat 600 to move to the limiting shaft 610 along the axial direction of the rotating shaft 210 to abut against the other end of the cylindrical frame 11, and the rotating shaft 210 can be driven by the motor 220 to rotate to keep the rotating axis stable. After the production of a filter element 10 is completed, the driving assembly 620 drives the limiting shaft 610 to move away from the cylindrical frame 11 and then to one side of the rotating shaft 210, and then the filter element 10 is pulled out from the rotating shaft 210 to replace another cylindrical frame 11, and it is very convenient to disassemble and replace the cylindrical frame 11.

[0032] See also Figures 2 to 4, in some embodiments of the present utility model, the driving assembly 620 includes a moving seat 621 movably disposed on the machine base 100. The moving seat 621 is connected to a first linear driver 622 that drives it to move horizontally perpendicular to the axial direction of the rotating shaft member 210. The movable seat 600 is connected to the moving seat 621 through a second linear driver 623 arranged parallel to the rotating shaft member 210. A discharge plate 700 is slidably disposed on the machine base 100. A through-hole portion 710 for the rotating shaft member 210 to pass through is formed on the discharge plate 700. The diameter of the through-hole portion 710 is smaller than the outer diameter of the cylindrical frame 11. The discharge plate 700 is connected to a third linear driver 720 that drives it to reciprocate along a direction parallel to the rotating shaft member 210. It can be understood that after the winding work of the first filter membrane 12 and the second filter membrane 13 is completed on the cylindrical frame 11, first, the second linear driver 623 drives the limiting shaft 610 to move away from the cylindrical frame 11 and no longer press against the cylindrical frame 11. The first linear driver 622 drives the limiting shaft 610 on the movable seat 600 to move to one side of the rotating shaft member 210 to leave a space for unloading the filter element 10. At this time, the third linear driver 720 is used to drive the discharge plate 700 to move from one end close to the motor 220 to the other end along a direction parallel to the rotating shaft member 210. During this process, the discharge plate 700 abuts against one end of the filter element 10 close to the motor 220, and the through-hole portion 710 on the discharge plate 700 moves axially relative to the rotating shaft member 210, so as to unload the filter element 10 from the rotating shaft member 210. It should be noted that the diameter of the through-hole portion 710 is smaller than the outer diameter of the cylindrical frame 11, so that when the discharge plate 700 abuts against the filter element 10, it contacts the end of the cylindrical frame 11, which is beneficial to the transmission of the thrust and avoids the positions of the first filter membrane 12 and the second filter membrane 13 where the filter element 10 is pushed by the discharge plate 700 from being excessively deformed.

[0033] In this embodiment, the first linear driver 622, the second linear driver 623, and the third linear driver 720 are all cylinders. Of course, in other embodiments, the first linear driver 622, the second linear driver 623, and the third linear driver 720 can also be replaced by electric push rods or electric lead screw mechanisms.

[0034] See Figure 3 and Figure 4, in some embodiments of the present utility model, an output end of the third linear driver 720 is connected with a mounting plate 721, and the discharge plate 700 is detachably mounted on the mounting plate 721. It should be noted that according to different diameter sizes of the filter element 10 to be manufactured, or according to different diameter sizes of the rotating shaft member 210, the corresponding size of the discharge plate 700 needs to be replaced. Therefore, the detachable mounting of the discharge plate 700 on the mounting plate 721 can meet the production requirements of different specifications of the filter element 10. In this embodiment, a calabash hole with a length direction pointing to the radial direction of the rotating shaft member 210 is further provided on the discharge plate 700, and a through hole corresponding to the calabash hole is provided on the mounting plate 721. A bolt assembly passes through the through hole and the calabash hole to fixedly connect the mounting plate 721 and the discharge plate 700, which can realize the concentric adjustment of the through hole portion 710 and the rotating shaft member 210 and avoid rubbing.

[0035] See Figure 3 and Figure 4In some embodiments of the utility model, the machine base 100 is provided with a material receiving assembly 800 which is arranged opposite to the end of the filter element 10 away from the motor 220, and the first linear drive 622 can move the limiting shaft 610 to one side of the filter element 10 to avoid the material receiving assembly 800, and the material receiving assembly 800 includes a first material receiving guide rail 810 and a second material receiving guide rail 820 which are both inclined downward, and the second material receiving guide rail 820 is telescopically movable along the length direction of the first material receiving guide rail 810, and the first material receiving guide rail 810 is provided with a telescopic drive 830 which drives the upper end of the second material receiving guide rail 820 to extend from the upper end of the first material receiving guide rail 810 toward the direction of the filter element 10, and the second material receiving guide rail 820 and the first material receiving guide rail 810 can jointly define a discharge trough for unloading the filter element 10. It is understandable that the length of the filter element 10 is relatively large. If the filter element 10 pushed out by the discharge plate 700 falls directly into the container for storing the filter element 10, the filter element 10 is easily damaged. The setting of the material receiving component 800 can reduce the probability of this problem occurring. In addition, since space needs to be reserved near the end of the rotating shaft 210 away from the motor 220 for the movable seat 600 to move, the general material receiving assembly 800 cannot approach the end of the rotating shaft 210 away from the motor 220 to better receive the filter element 10 that has fallen off the rotating shaft 210. The material receiving assembly 800 of the above structure can extend the second material receiving guide rail 820 along the length direction of the first material receiving guide rail 810 and move it to the end close to the rotating shaft 210. The filter element 10 slides downward along the slope of the second material receiving guide rail 820 and the first material receiving guide rail 810 to the container for storing the filter element 10. Before the rotating shaft 210 needs to install another cylindrical frame 11, the second material receiving guide rail 820 is retracted along the length direction of the first material receiving guide rail 810, and the movable seat 600 moves to the limit shaft 610 with the cooperation of the first linear drive 622 and the second linear drive 623 to support the end of the cylindrical frame 11 away from the motor 220.

[0036] See also Figure 1 , Figure 2 and Figure 3 In some embodiments of the utility model, the welding device 400 includes a first lifting drive 410 and a welding knife 420 connected to the first lifting drive 410 and parallel to the rotating shaft 210, the film material supply device 300 includes a film feeding platform for flattening the first filter membrane 12 and the second filter membrane 13, and the end of the film feeding platform is located on one side of the rotating shaft 210, the displacement drive mechanism 500 includes a clamping assembly 510 movably arranged between the rotating shaft 210 and the film feeding platform and a fourth linear drive 520 for driving the clamping assembly 510 to move close to or away from the side wall of the rotating shaft 210, and the clamping assembly 510 is used to clamp and fix the first filter membrane 12.

[0037] It should be noted that after the cylindrical skeleton 11 is inserted into the rotating shaft member 210, the first filter membrane 12 moves along the surface of the film feeding platform to extend to the bottom side of the rotating shaft member 210. At this time, the clamping assembly 510 clamps the end of the first filter membrane 12, and the first lifting driver 410 drives the welding knife 420 to move upward to thermally press and weld the end edge of the first filter membrane 12 on the outer peripheral wall of the cylindrical skeleton 11, ensuring that the welding knife 420 can accurately abut against the end of the first filter membrane 12. Then, the first lifting driver 410 drives the welding knife 420 to move downward to reset, and the clamping assembly 510 releases the first filter membrane 12. The motor 220 drives the rotating shaft member 210 to rotate a preset angle and then stops, so that the first filter membrane 12 wraps around the outer peripheral wall of the cylindrical skeleton 11 for at least one circle. Then, the pre-cut second filter membrane 13 is stacked on the first filter membrane 12 on the film feeding platform. Then, the motor 220 continues to rotate to wind the stacked first filter membrane 12 and second filter membrane 13 together until the second filter membrane 13 is completely wrapped around the cylindrical skeleton 11, and then the first filter membrane 12 continues to cover the second filter membrane 13 inside. The clamping assembly 510 clamps the first filter membrane 12 again to prevent the first filter membrane 12 from shaking. Then, the first lifting driver 410 drives the welding knife 420 to move upward to thermally press and weld the first filter membrane 12 on the outer peripheral wall of the first filter membrane 12, preventing the wrapped first filter membrane 12 and second filter membrane 13 from loosening. Finally, the fourth linear driver 520 drives the clamping assembly 510 to move away from the side wall of the rotating shaft member 210 to break the first filter membrane 12 along the weld position, so that the filter element 10 and the unwound first filter membrane 12 are separated. The filter material winding and welding equipment for the filter element with the above structure improves the automation degree of filter material winding and welding, which is beneficial to ensuring the quality and reliability of the filter element 10.

[0038] Among them, it should be noted that when driving the first filter membrane 12 to wrap around the outer peripheral wall of the cylindrical skeleton 11 for at least one circle, the motor 220 drives the rotating shaft member 210 to rotate a preset angle and then stops for a period of time. During this period, the second filter membrane 13 cut into a predetermined shape can be manually stacked on the first filter membrane 12, and then the motor 220 automatically starts to operate again, or the motor 220 can be controlled to start to operate again by pressing a key.

[0039] See Figure 3 and Figure 4, in some embodiments of the present utility model, a lifting seat 530 is provided on the machine base 100. A first sliding seat 540 located between the rotating shaft member 210 and the film feeding platform is movably arranged on the lifting seat 530. The fourth linear driver 520 is fixedly arranged on the lifting seat 530 to drive the first sliding seat 540 to reciprocate between the rotating shaft member 210 and the film feeding platform. The lifting seat 530 can move up and down to adjust the height distance between the clamping assembly 510 and the axis of the rotating shaft member 210. It can be understood that the first filter membrane 12 and the second filter membrane 13 are wound on the cylindrical skeleton 11, resulting in a change in the diameter size of the filter element 10, so that the first filter membrane 12 and the second filter membrane 13 cannot be supplied tangentially, affecting the winding quality. The above technical problem can be solved by moving the lifting seat 530 up and down to adjust the height position of the first filter membrane 12 and the second filter membrane 13 when they are output. In addition, fixedly arranging the fourth linear driver 520 on the lifting seat 530 will not affect the function of breaking the first filter membrane 12 along the weld position.

[0040] See Figure 3 and Figure 4 , in some embodiments of the present utility model, the clamping assembly 510 includes a material supporting flat plate 511 parallel to the film feeding platform and a movable clamping plate 512 that moves up and down relative to the material supporting flat plate 511. At least two guiding rollers 513 for the first filter membrane 12 and the second filter membrane 13 to pass through in sequence are provided between the material supporting flat plate 511 and the end of the film feeding platform. It should be noted that the first filter membrane 12 or the second filter membrane 13 on the film feeding platform contacts the material supporting flat plate 511 after passing through at least one guiding roller 513, and then winds on the cylindrical skeleton 11 after passing through at least one guiding roller 513. The arrangement of the guiding rollers 513 can prevent the first filter membrane 12 and the second filter membrane 13 from wrinkling in their width directions and can also limit the backward retraction of the first filter membrane 12 and the second filter membrane 13 along their conveying directions. The movable clamping plate 512 is driven by a cylinder to descend to clamp the first filter membrane 12, and the cylinder drives the movable clamping plate 512 to rise to release the first filter membrane 12.

[0041] See Figure 2, in some embodiments of the present utility model, the film feeding platform is strip-shaped. One end of the film feeding platform is close to the clamping assembly 510, and a film unwinding mechanism 910 for unwinding the first filter membrane 12 is provided at the other end of the film feeding platform. A plurality of suction holes are arranged along the length direction of the film feeding platform, and all the suction holes communicate with an exhaust cavity, and the exhaust cavity is connected to an air extraction pump. It can be understood that after the end edge of the first filter membrane 12 is thermally pressed and fixed to the cylindrical skeleton 11, the motor 220 drives the rotating shaft member 210 to rotate to drive the cylindrical skeleton 11 to rotate, and the film unwinding mechanism 910 can gradually release the first filter membrane 12. Since the film feeding platform has a certain length, the first filter membrane 12 may wrinkle during the process of moving along the length direction of the film feeding platform. By using the air extraction pump to exhaust the air in the exhaust cavity, a negative pressure can be formed at the suction holes to adsorb the first filter membrane 12 and ensure that the first filter membrane 12 is in an extended state.

[0042] See Figure 1 , in some embodiments of the present utility model, in order to better limit the positions of the first filter membrane 12 and the second filter membrane 13 in the width direction and ensure that the positions of the first filter membrane 12 and the second filter membrane 13 supplied to the cylindrical skeleton 11 for winding are accurate in the width direction, at least one side of the film feeding platform is provided with a guiding and positioning strip 920 that can abut against the side edges of the first filter membrane 12 and the second filter membrane 13. The guiding and positioning strip 920 extends along the length direction of the film feeding platform.
