Description

Technical Field

[0001] The present invention relates to the technical field of dialyzer production, and specifically to a wire cutting device and a wire cutting method for collecting hollow fiber membrane filaments. Background Art

[0002] A dialyzer is composed of hollow fibers, a housing, a sealing layer, and end caps. It mainly uses the principle of a semi-permeable membrane to introduce the patient's blood and dialysate into the dialyzer simultaneously, making the two flow in opposite directions in the dialysate chamber and the blood chamber, and relying on the solute gradient, osmotic gradient, and hydrostatic pressure gradient on both sides of the membrane to achieve the functions of removing blood toxins, supplementing blood nutrients, and adjusting the blood pH value. The slender hollow fibers made of the dialysis membrane are formed into continuous filaments after spinning, washing, drying, and bending, and the filament collecting mechanism collects the filaments into bundles. At this time, a wire cutting device is required to cut the bundled filaments into a specified length.

[0003] Since the filaments are hollow as a whole, some fiber debris generated during the cutting of the bundled filaments will fall into the interior of the filaments driven by the cutting knife. In the subsequent process of removing toxins and impurities in the blood by the filaments, due to the presence of fiber debris inside the filaments, the toxins and impurities are likely to be blocked when flowing inside the filaments, ultimately resulting in poor overall osmotic effect of the filaments.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a wire cutting device and a wire cutting method for hollow fiber membrane wire winding, which have the following beneficial effects:

[0021] 1. Through the pushing component of the present invention, the plastic connection part for connecting the membrane filaments can be directly moved into the socket component. At this time, the air flow transportation component can transport air flow into the membrane filaments through the socket component, so that when the cutting component cuts the membrane filaments, the fiber debris falling into the membrane filaments can continuously flow backward under the blowing of the air flow. This setting ensures that there is no fiber debris inside the cut membrane filaments, thus ensuring the penetration effect when the membrane filaments subsequently clean toxins and impurities in the blood.

[0022] 2. By moving the plastic connection end of the membrane filaments into the sleeve pipe of the present invention, the L-shaped air pipe transports air flow into the membrane filaments through the hollow ball, the L-shaped hole and the conical air hole. The air flow inside the membrane filaments can make the whole membrane filaments bulge. This phenomenon makes it not easy for the cutting position to be uneven at the port due to the pressing of the cutting knife when the cutting knife cuts the membrane filaments, thus making it more convenient to seal one end of the membrane filaments subsequently.

[0023] 3. In the present invention, the plastic connection part on the membrane filament can be normally moved into the inside of the sleeve pipe through the clamping plate. Meanwhile, under the push of the clamping plate, when the air flow flows into the inside of the membrane filament, the plastic connection part will not move out of the inside of the sleeve pipe under the blowing of the air flow. After the membrane filament is cut, the clamping plate can rotate with the assistance of the blocking of the sleeve pipe and the rotating shaft and torsion spring, and the clamping plate can normally move to the bottom of the workbench through the driving groove, so that the pushing component can continuously push the membrane filament.

Detailed implementation mode

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, this application proposes a wire cutting device and a wire cutting method for collecting filaments of hollow fiber membranes.

[0036] Please refer to Figures 1-9 , a wire cutting device for collecting filaments of hollow fiber membranes, including a workbench 1. A pushing component 2 is arranged on the top of the workbench 1. A sleeving component 3 is rotatably connected to the top of the workbench 1. An air flow conveying component 4 is arranged inside the sleeving component 3. A cutting component 5 is arranged on the top of the workbench 1. A fixing component 6 is arranged on the moving end of the cutting component 5. A guiding component 7 is arranged on the front side of the workbench 1 corresponding to the sleeving component 3.

[0037] The bundled membrane filaments are connected together by plastic. The distance between the plastics on the outer surface of the bundled membrane filaments is the length at which the membrane filaments need to be cut. Then, the connected membrane filaments are placed on the pushing component 2, so that the pushing component 2 pushes the membrane filaments and directly moves the plastic connection part into the socket component 3. At this time, the next plastic connection part of the membrane filaments is exactly below the cutting component 5. Then, the air flow transportation component 4 transports air flow into the hollow membrane filaments through the socket component 3. At the same time, after the fixing component 6 clamps and fixes the plastic connection part below the cutting component 5, the cutting component 5 starts to perform the cutting operation on the membrane filaments.

[0038] Through the pushing component 2, the plastic connection part used to connect the membrane filaments can be directly moved into the socket component 3. At this time, the air flow transportation component 4 can transport air flow into the membrane filaments through the socket component 3. Thus, when the cutting component 5 cuts the membrane filaments, the fiber debris falling into the membrane filaments can continuously flow backward under the blowing of the air flow. This setting ensures that there is no fiber debris inside the cut membrane filaments, thereby guaranteeing the penetration effect when the membrane filaments subsequently clean toxins and impurities in the blood.

[0039] Further, for the above-mentioned pushing component 2, the pushing component 2 includes a transportation component 21 and a clamping component 22. The transportation component 21 includes a transportation belt 211. Two transportation belts 211 are symmetrically arranged. A driving groove 212 is correspondingly opened at the top of the workbench 1 for the transportation belt 211. A roller 213 is rotatably connected inside the driving groove 212. The transportation belt 211 is arranged on the outside of the roller 213. A transportation motor 214 is fixedly installed on the back of the workbench 1. The output end of the transportation motor 214 is fixedly connected to the roller 213.

[0040] The transportation motor 214 can drive the transportation belt 211 through the roller 213, so that the transportation belt 211 can drive the clamping component 22 to move on the workbench 1. At this time, the clamping component 22 pushes the membrane filaments through the position where the plastics on the membrane filaments are connected and directly moves the plastic connection position on the membrane filaments into the socket component 3. The above-mentioned clamping component 22 mainly completes the pushing of the membrane filaments driven by the two transportation belts 211. This setting ensures that the two transportation belts 211 are not directly below the cutting end of the cutting component 5. Coupled with the clamping component 22 being behind the plastic connection position of the membrane filaments, the cutting component 5 will not damage the overall pushing component 2 when cutting the membrane filaments.

[0041] Further, for the above-mentioned clamping component 22, the clamping component 22 includes a connecting bar 221, the connecting bar 221 is fixedly connected to the conveyor belt 211, a connecting block 222 is fixedly connected to the top of the connecting bar 221, a rotating shaft 223 is rotatably connected to one side of the connecting block 222, a clamping plate 224 is fixedly connected to the outer surface of the rotating shaft 223, an installation cylinder 225 is fixedly connected to one side of the connecting block 222, the rotating shaft 223 is rotatably connected to the installation cylinder 225, and a torsion spring 226 is fixedly connected between the inner wall of the installation cylinder 225 and the outer surface of the rotating shaft 223.

[0042] By placing the membrane filaments inside the card slots on the clamping plate 224, and at the same time, the rear side of the plastic connecting part on the membrane filaments is in direct contact with the clamping plate 224. At this time, the clamping plate 224 can move under the drive of the conveyor belt 211. Meanwhile, the clamping plate 224 directly pushes the bundled membrane filaments through the plastic connecting part. When the plastic connecting part moves inside the socket component 3, the conveyor belt 211 stops working. At this time, the clamping plate 224 can continue to push the plastic connecting part, so that when the air flow transportation component 4 transports air into the membrane filaments through the socket component 3, the plastic connecting part will not move out of the socket component 3 under the blowing of the air flow. After cutting is completed, the conveyor belt 211 drives the clamping plate 224 to continue moving. At this time, since the clamping plate 224 is blocked by the socket component 3, the rotating shaft 223 on the clamping plate 224 can pull and rotate the torsion spring 226, so that the clamping plate 224 can tilt backward and move to the bottom of the workbench 1 through the driving groove 212. The setting of the torsion spring 226 enables the clamping plate 224 to normally move to the top of the workbench 1 after pushing the plastic connecting part of the membrane filaments into the socket component 3, so that the pushing component 2 can continuously push the membrane filaments. At the same time, when pushing the membrane filaments, it is mainly completed by the cooperation of multiple clamping components 22 arranged on the conveyor belt 211, so that the clamping plate 224 is not prone to tilting when pushing the membrane filaments.

[0043] Further, for the above-mentioned socket component 3, the socket component 3 includes a rotating tube 301, the rotating tube 301 is rotatably connected to the workbench 1, a sleeve tube 302 is fixedly connected to the top of the rotating tube 301, a plurality of sleeve tubes 302 are arranged in a circumferential array, a tapered air hole 303 is opened in the inner wall of the sleeve tube 302, a driving motor 304 is fixedly installed on the top of the workbench 1, a driving gear 305 is fixedly connected to the output end of the driving motor 304, a driven gear 306 is engaged with the outer surface of the driving gear 305, and the driven gear 306 is fixedly connected to the outer surface of the rotating tube 301.

[0044] The plastic connection part of the membrane filament can be directly moved into the inside of the sleeve pipe 302 under the push of the clamping plate 224. At this time, the air flow transportation component 4 can transport the air flow into the inside of the sleeve pipe 302 through the conical air hole 303, so that the air flow can directly flow into the inside of the membrane filament, enabling the air flow to flow inside the membrane filament. When the cutting is completed, the driving motor 304 can drive the driving gear 305 to rotate, and the driving gear 305 drives the rotating pipe 301 to rotate through the driven gear 306. The rotating pipe 301 drives a plurality of sleeve pipes 302 to rotate, and the sleeve pipe 302 sleeved with the plastic connection part can be directly rotated to the front of the workbench 1. This setting enables the cut membrane filament to rotate to the front of the workbench 1, making it convenient to collect the cut membrane filament, and at the same time, it will not hinder the subsequent cutting operation during the collection process.

[0045] Further, for the above-mentioned air flow transportation component 4, the air flow transportation component 4 includes an L-shaped air pipe 401. The L-shaped air pipe 401 is movably connected to the rotating pipe 301. A ball groove 402 is opened inside the connection part of a plurality of sleeve pipes 302. A hollow ball 403 is movably connected inside the ball groove 402. The top end of the L-shaped air pipe 401 is fixedly connected to the hollow ball 403. The conical air hole 303 extends into the ball groove 402. An L-shaped hole 404 is opened on the outer surface of the hollow ball 403 corresponding to the conical air hole 303. A fixed seat 405 is fixedly installed at the bottom of the workbench 1. The L-shaped air pipe 401 is sleeved inside the fixed seat 405.

[0046] One end of the L-shaped air pipe 401 can be connected to an external air source, so that the air flow generated by the external air source can flow into the inside of the hollow ball 403 through the L-shaped air pipe 401. At this time, the air flow inside the hollow ball 403 flows into the inside of two sleeve pipes 302 through the L-shaped hole 404 and the corresponding conical air hole 303. At this time, one of the two sleeve pipes 302 transports the air flow to the membrane filament being cut, and one sleeve pipe 302 is located in front of the workbench 1, so that the plastic connection part inside the sleeve pipe 302 can automatically move out of the sleeve pipe 302 under the blowing of the air flow. As the sleeve pipe 302 rotates intermittently, the cut membrane filament inside the sleeve pipe 302 can be automatically unloaded. The setting of the fixed seat 405 makes the L-shaped air pipe 401 not rotate with the rotating pipe 301. When the rotating pipe 301 rotates, only the hollow ball 403 rotates inside the ball groove 402, so that the air flow inside the hollow ball 403 can always transport the air flow in the same direction.

[0047] Further, for the above-mentioned cutting component 5, the cutting component 5 includes a mounting frame 501, the mounting frame 501 is fixedly connected to the workbench 1, a lifting hydraulic cylinder 502 is fixedly installed at the top of the mounting frame 501, the output end of the lifting hydraulic cylinder 502 penetrates through the mounting frame 501 and is fixedly connected to a lifting plate 503, and a cutting knife 504 is fixedly installed at the bottom of the lifting plate 503.

[0048] When the clamping plate 224 drives the plastic connecting part on the film wire to move into the inside of the sleeve 302, the plastic connecting part on one side of the next clamping plate 224 also moves to the lower side of the cutting knife 504. At this time, the lifting hydraulic cylinder 502 drives the lifting plate 503 to move downward, and the cutting knife 504 moves downward under the drive of the lifting plate 503 and cuts the film wire on one side of the plastic connecting part. The shape of the mounting frame 501 is set so that there is no obstruction on one side of the lifting plate 503. This setting makes it convenient for the operator to view the cutting situation. At the same time, it is also convenient to replace the cutting knife 504 at the bottom of the lifting plate 503.

[0049] Further, for the above-mentioned fixing component 6, the fixing component 6 includes a bidirectional screw 601, the bidirectional screw 601 is rotatably connected to the inner wall of the mounting frame 501, a moving rod 602 is threadedly connected to the outer surface of the bidirectional screw 601, the lifting plate 503 is provided with a moving groove 603 corresponding to the moving rod 602, the moving rod 602 is movably connected to the moving groove 603, a fixing block 604 is fixedly connected to one side of the moving rod 602, and a fixing motor 605 is fixedly installed on the back of the mounting frame 501, and the output end of the fixing motor 605 is fixedly connected to the bidirectional screw 601.

[0050] When cutting the film wire, the fixing motor 605 can drive the bidirectional screw 601, so that the bidirectional screw 601 drives the two moving rods 602 to slide inside the moving groove 603, and the fixing blocks 604 on the two moving rods 602 can clamp and fix the plastic connecting part under the cutting knife 504, so that the plastic connecting part will not shake when the cutting knife 504 cuts the film wire on one side of the plastic connecting part. The setting of the moving groove 603 enables the moving rod 602 not to obstruct the lifting plate 503 from driving the cutting knife 504 to slide downward.

[0051] Further, for the above-mentioned material guiding component 7, the material guiding component 7 includes a mounting plate 701, the mounting plate 701 is fixedly installed on the front surface of the workbench 1, an inclined material guiding plate 702 is fixedly connected to one side of the mounting plate 701, an L-shaped shielding plate 703 is fixedly connected to the top of the inclined material guiding plate 702, and a ventilation groove 704 is opened on one side of the L-shaped shielding plate 703.

[0052] When the plastic connection part inside the sleeve pipe 302 is blown out by the airflow, at this time, the plastic connection part can drive the cut film filaments to contact the L-shaped baffle 703 and roll down under the guidance of the inclined guide plate 702. A collection box can be arranged at the bottom of the inclined guide plate 702, so that the cut film filaments can directly fall into the interior of the collection box under the guidance of the inclined guide plate 702. The above setting makes it so that when the plastic connection part is blown out of the interior of the sleeve pipe 302 by the airflow, there will be no phenomenon of random flying. At the same time, the L-shaped baffle 703 is made of rubber, so that the film filaments will not be damaged after contacting the L-shaped baffle 703. The setting of the ventilation groove 704 makes it so that the airflow will not accumulate inside the L-shaped baffle 703.

[0053] Furthermore, for the above-mentioned sleeve pipe 302, a push plate 8 is fixedly connected between two adjacent sleeve pipes 302.

[0054] When the rotating pipe 301 drives the sleeve pipe 302 to rotate, the push plate 8 can push the cut film filaments, so that the cut film filaments will not stay at the cutting position for too long, making it more convenient to collect the cut film filaments.

[0055] Through the above technical solutions: 1. By pushing the pushing component 2, the plastic connecting part for connecting the membrane filaments can be directly moved into the socket component 3. At this time, the air flow transportation component 4 can transport air flow into the interior of the membrane filaments through the socket component 3. As a result, when the cutting component 5 cuts the membrane filaments, the fiber debris falling into the interior of the membrane filaments can continuously flow backward under the blowing of the air flow. This setting ensures that there is no fiber debris inside the cut membrane filaments, thus guaranteeing the penetration effect when the membrane filaments subsequently clean toxins and impurities in the blood; 2. By moving the plastic connecting end of the membrane filaments into the interior of the socket pipe 302, the L-shaped air pipe 401 transports air flow into the interior of the membrane filaments through the hollow ball 403, the L-shaped hole 404, and the tapered air hole 303. The air flow inside the membrane filaments can cause the entire membrane filaments to bulge. This phenomenon makes it less likely that the cutting position of the cutting knife 504 is uneven at the port due to the pressing of the cutting knife 504 when cutting the membrane filaments, thus making it more convenient to seal one end of the membrane filaments subsequently; 3. The clamping plate 224 enables the plastic connecting part on the membrane filaments to normally move into the interior of the socket pipe 302. At the same time, under the push of the clamping plate 224, when the air flow flows into the interior of the membrane filaments, the plastic connecting part will not move out of the interior of the socket pipe 302 under the blowing of the air flow. After the membrane filaments are cut, the clamping plate 224 can rotate under the block of the socket pipe 302 and with the assistance of the rotating shaft 223 and the torsion spring 226, and the clamping plate 224 can normally move to the bottom of the workbench 1 through the driving groove 212, so that the pushing component 2 can continuously push the membrane filaments.

[0056] A filament cutting method based on a filament winding and cutting device for hollow fiber membranes:

[0057] Step 1: Clamp the membrane filaments onto the clamping plate 224 and make the plastic connecting part on the membrane filaments contact the clamping plate 224. At this time, the conveyor belt 211 drives the clamping plate 224 to move through the connecting bar 221, and the clamping plate 224 drives the membrane filaments through the plastic connecting part, so that the plastic connecting part is directly moved into the interior of the socket pipe 302;

[0058] Step 2: The fixed motor 605 clamps and fixes the plastic connecting part below the cutting knife 504 through the bidirectional screw 601, the moving rod 602, and the fixed block 604. At the same time, the L-shaped air pipe 401 conveys air flow into the interior of the socket pipe 302 through the hollow ball 403, the L-shaped hole 404, and the tapered air hole 303. The air flow inside the socket pipe 302 directly flows into the interior of the membrane filaments, and then the cutting knife 504 cuts the membrane filaments under the drive of the lifting hydraulic cylinder 502 and the lifting plate 503;

[0059] Step 3: After cutting is completed, the conveyor belt 211 drives the clamping plate 224 to move. At this time, blocked by the sleeve 302, the clamping plate 224 drives the rotating shaft 223 to pull and rotate the torsion spring 226, so that the clamping plate 224 can tilt backward and move to the bottom of the workbench 1 through the driving groove 212.

[0060] Step 4: The drive motor 304 drives the sleeve 302 to rotate through the driving gear 305, the driven gear 306 and the rotating tube 301, and the sleeve 302 sleeved with the plastic connection part directly rotates to the front of the workbench 1.
