Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an artificial lung membrane fiber weaving machine. Background Technology

[0002] Due to the rapid development of medical devices, the demand for automation and process improvement in equipment is increasing, including artificial lung membrane wire braiding machines. Currently, the braiding method for artificial lung membrane wires involves laying out individual membrane wires and then weaving them together with braiding threads to create the required material. Membrane wires are generally tubular flexible materials with a diameter of approximately 0.5 mm and a static load-bearing capacity of only about 0.3 N, while the diameter of the braiding thread is approximately 0.04 mm. The common braiding method is right-angle single-layer braiding, which has low gas exchange efficiency, a high risk of thrombosis during later use, and rapid performance degradation. Therefore, oblique double-layer braiding can better solve the problems of right-angle single-layer braiding. Double-layer oblique braiding involves stacking two layers of braided pads at a certain angle to the membrane wires, with different angles between the membrane wires. This results in a cross-shaped arrangement of the membrane wires in the two layers of braided pads, and the angle needs to be adjustable to meet the requirements. However, to achieve oblique braiding, it is usually necessary to stretch the right-angle braid at an angle, which has the following shortcomings:

[0003] 1. It easily damages the membrane fiber structure, leading to changes in the oxygen flux of the membrane fibers;

[0004] 2. The angle of the bevel is inconvenient to adjust;

[0005] 3. To ensure precise cutting of the width direction of the woven membrane fibers, ultrasonic cutting is often used. However, this method has high requirements for the ratio of membrane fiber components, resulting in different cutting effects. Furthermore, it is difficult to adjust different widths, leading to poor cutting consistency and high after-sales costs.

[0006] Therefore, how to achieve adjustable bevel weaving, avoid damaging the membrane fibers, and achieve precise cutting is a problem that needs to be solved by those in the field. Summary of the Invention

[0007] The purpose of this invention is to provide an artificial lung membrane fiber weaving machine to achieve adjustable oblique angle weaving, avoid damage to the membrane fibers, and achieve precise cutting.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] Artificial lung membrane fiber weaving machine, which includes:

[0010] The base and platform, with the platform located on top of the base.

[0011] The platform is symmetrically equipped with at least two sets of membrane fiber feeding devices, membrane fiber weaving equipment, weaving thread feeding devices, detection devices, and take-up devices. The membrane fiber feeding device is used for feeding membrane fibers, and the weaving thread feeding device is used for feeding weaving threads. The membrane fibers and the weaving thread are woven at the membrane fiber weaving equipment, and the membrane fiber weaving equipment can rotate at any angle relative to the platform so that the weaving thread and the membrane fibers are woven at an oblique angle to form a membrane curtain. The detection device can detect defects in the membrane curtain. One of the two sets of take-up devices can combine the two sets of membrane curtains into a roll to complete the take-up.

[0012] Optionally, the membrane weaving device includes a gear, a ring rack, a guide rail, a slider, and a rotating platform. The guide rail is disposed on the ring rack and both are fixedly connected to the platform. The slider is disposed on the gear and slidably disposed in the guide rail. The gear and the ring rack mesh with each other. The rotating platform is connected to the slider. When the gear moves circumferentially along the ring rack, the slider moves synchronously with the gear and drives the rotating platform to rotate relative to the platform.

[0013] Optionally, the rotating platform is provided with a support beam, and the membrane yarn weaving equipment includes a yarn-laying device and a knotting device. The knotting device is fixed on the support beam, and the yarn-laying device is slidably disposed on the knotting device. The yarn-laying device is used for the yarn-laying operation of the membrane yarn, and the knotting device can knot the membrane yarn with the weaving thread.

[0014] Optionally, the membrane fiber weaving equipment may further include a wire hooking device and a looping device, both of which are mounted on the rotating platform to knot the membrane fiber and the weaving thread.

[0015] Optionally, the artificial lung membrane filament braiding machine further includes a primary tension balancing device and a secondary tension balancing device. The primary tension balancing device is located between the membrane filament feeding device and the membrane filament braiding device for primary guidance of the membrane filament. The secondary tension balancing device is located on the membrane filament braiding device and can rotate synchronously with the membrane filament braiding device for secondary guidance of the membrane filament.

[0016] Optionally, the artificial lung membrane filament braiding machine further includes an auxiliary filament feeding device, which is disposed on the membrane filament braiding equipment. The auxiliary filament feeding device can rotate synchronously with the membrane filament braiding equipment and is located between the primary tension balancing device and the secondary tension balancing device for conveying the membrane filament.

[0017] Optionally, the artificial lung membrane weaving machine also includes a feeding device and a cutting device, wherein the membrane curtain is fed by the feeding device and then cut at the cutting device.

[0018] Optionally, the cutting device includes at least two sets of cutter wheel mounting seats, each set having a cutting wheel mounted thereon, and the distance between the two sets of cutter wheel mounting seats is adjustable.

[0019] The cutting device also includes a support adjustment assembly, which is configured to correspond one-to-one with the cutting wheel, and the support adjustment assembly can move toward or away from the cutting wheel.

[0020] Optionally, the artificial lung membrane weaving machine further includes a buffer device, the detection device being located between the cutting device 80 and the buffer device, the buffer device being located between the detection device and the receiving device, and the buffer device being used to balance the tension of the membrane curtain.

[0021] Optionally, the detection device includes a detection camera and a strip light source. The height of the detection camera is adjustable, and at least two sets of strip light sources are symmetrically arranged. The detection camera and the strip light sources work together to detect defects in the membrane curtain.

[0022] The beneficial effects of this invention are:

[0023] In this invention, the film filament feeding device ensures smooth feeding of the film filaments, and the braiding thread feeding device ensures smooth feeding of the braiding thread. The rotational setting of the film filament weaving equipment relative to the platform enables the film filaments and braiding thread to be woven at an angle to form a film curtain. The detection device can detect defects in the film curtain for quality control. One of the two sets of take-up devices can gather the two sets of film curtains into a roll to complete the take-up. This not only has high take-up efficiency but also effectively ensures the roll-up effect of the film curtain. Thus, adjustable angled weaving is achieved, avoiding damage to the film filaments while achieving precise cutting. Attached Figure Description

[0068] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0069] like Figure 1As shown, this embodiment provides an artificial lung membrane fiber braiding machine, mainly used for the double-layer inclined braiding operation of artificial lung membrane fibers in the field of medical devices. It mainly includes a base 1, a platform 2, and a protective cover 3. The platform 2 is located on top of the base 1, and the protective cover 3 is placed above the platform 2 to protect personnel and prevent accidental entry and injury during equipment operation. Specifically, the platform 2 has at least two sets of symmetrically and mirror-imagely arranged membrane fiber feeding devices 10, primary tension balancing devices 20, auxiliary fiber feeding devices 30, secondary tension balancing devices 40, membrane fiber braiding equipment 50, braiding wire feeding devices 60, feeding devices 70, cutting devices 80, detection devices 90, buffer devices 100, and receiving devices 110. Specifically, the membrane fiber feeding device 10 is used for feeding the membrane fibers, and the primary tension balancing device 20, auxiliary fiber feeding device 30, and secondary tension balancing device 40 are used to balance the tension of the membrane fibers to smoothly transport the membrane fibers to the membrane fiber braiding equipment 50. Furthermore, the braiding thread feeding device 60 is used to feed the braiding thread, and the membrane filaments and braiding thread are woven at the membrane filament braiding device 50 to form a finished membrane curtain for use. Specifically, in this embodiment, the membrane filament braiding device 50 can rotate at any angle relative to the membrane filament feeding device 10 and the braiding thread feeding device 60 so that the braiding thread and membrane filaments are woven at an oblique angle to meet the needs of different membrane curtains. Furthermore, after the membrane curtain is fed by the feeding device 70, it can be cut at the cutting device 80, and the membrane curtain can be defectively detected at the detection device 90. Optionally, in this embodiment, one of the two sets of receiving devices 110 can collect the two sets of membrane curtains into a roll to complete the receiving, thereby enabling the membrane curtains on both sides of the platform 2 to be collected and rolled up uniformly.

[0070] like Figures 2-4 As shown, in this embodiment, the film filament feeding device 10 includes a first base 11, a first guide rail 12, a first slider 13, a first mounting base 14, an air shaft 15, a second mounting base 16, a first drive mechanism 17, a first transmission assembly 18, and a first cylinder 19. Optionally, in this embodiment, the first base 11 is vertically mounted on the platform 2, and the first guide rail 12 is arranged parallel to the first base 11 and fixedly connected to the first base 11. Further, the first slider 13 is slidably disposed on the first guide rail 12 and can slide along the extension direction of the first guide rail 12. Further, the first mounting base 14 and the second mounting base 16 are both connected to the first slider 13, thereby slidably connected to the first guide rail 12 through the first slider 13. Optionally, the first cylinder 19 is disposed on the first base 11, and the extension direction of the first cylinder 19 is the same as the extension direction of the first guide rail 12. The first cylinder 19 is used to drive the first mounting base 14 and the second mounting base 16 to move along their extension directions.

[0071] Specifically, a clearance channel 111 is provided on the first base 11 along its extension direction. The air shaft 15 passes through the clearance channel 111 and is connected to the first mounting base 14. This allows the air shaft 15 to move synchronously within the clearance channel 111 when the first cylinder 19 drives the first mounting base 14, thereby changing the height between the air shaft 15 and the platform 2 and preventing interference with the movement of the air shaft 15 due to the clearance channel 111. Further, a first transmission assembly 18 is installed between the second mounting base 16 and the first mounting base 14. The first transmission assembly 18 includes a first driving wheel, a first driven wheel, and a first belt. The second mounting base 16 is used to mount a first drive mechanism 17, which includes a motor and a reducer connected to each other. Optionally, the output end of the reducer is connected to the first driving wheel, and the first driving wheel and the first driven wheel are connected by a first belt. The first driven wheel is connected to the air shaft 15. Thus, under the drive of the first drive mechanism 17, the air shaft 15 can be rotated through the first transmission assembly 18 to realize the feeding operation of the membrane filaments. Further, a membrane filament material tray 151 is sleeved on the air shaft 15, and two membrane filament material trays 151 are provided. Specifically, the two membrane filament material trays 151 are spaced apart along the axial direction of the air shaft 15, and the membrane filament material is located between the two membrane filament material trays 151, thereby limiting and fixing the membrane filament material to prevent it from falling off. Exemplarily, the first base 11 is assembled from aluminum plates.

[0072] like Figure 5 and Figure 6 As shown, in this embodiment, the primary tension balancing device 20 is disposed between the membrane fiber feeding device 10 and the membrane fiber weaving device 50 for primary guidance of the membrane fibers. Specifically, in this embodiment, the primary tension balancing device 20 includes a second base 21, a guide plate 22, a counterweight 23, a connecting frame 24, and a first sensor 25. Optionally, in this embodiment, the second base 21 is fixed on the platform 2, and a vertical plate 211 and a support frame 212 are disposed on the second base 21. The vertical plate 211 is disposed perpendicular to the second base 21, and the support frame 212 is connected to the vertical plate 211 and the guide plate 22 respectively. Specifically, the guide plate 22 is disposed in the vertical direction, and a guide groove 221 is disposed in the guide plate 22 in the vertical direction. The counterweight 23 is slidably disposed in the guide groove 221, and the counterweight 23 can move along the extension direction of the guide groove 221.

[0073] Furthermore, at least one end of the guide plate 22 is provided with a connecting frame 24, and the connecting frame 24 is connected to a first sensor 25. Specifically, the membrane filament is threaded through the counterweight 23, and the counterweight 23 slides and changes position in the guide groove 221 according to the tension change of the membrane filament. The first sensor 25 can then provide a signal corresponding to the movement position of the counterweight 23, thereby controlling the movement process of the counterweight 23. Exemplarily, in this embodiment, both the upper and lower ends of the guide plate 22 are provided with connecting frames 24, and each connecting frame 24 is provided with a first sensor 25, thereby monitoring the up and down movement of the counterweight 23 through the first sensors 25 at both ends. Optionally, the top of the upright plate 211 is also provided with a first guide wheel 201, thereby guiding the membrane filament at the membrane filament feeding device 10 to the counterweight 23 via the first guide wheel 201, ensuring stable delivery of the membrane filament. Exemplarily, the second base 21 is made of spliced ​​aluminum plates.

[0074] like Figures 7-12 As shown, the secondary tension balancing device 40 is mounted on the membrane fiber weaving equipment 50 and can rotate synchronously with the membrane fiber weaving equipment 50 to provide secondary guidance for the membrane fibers, ensuring smooth delivery of the membrane fibers to the membrane fiber weaving equipment 50. Exemplarily, the secondary tension balancing device 40 can be configured as needed, and is not limited here. Further, the auxiliary fiber feeding device 30 is mounted on the membrane fiber weaving equipment 50 and can rotate synchronously with the membrane fiber weaving equipment 50. The auxiliary fiber feeding device 30 is located between the first tension balancing device 20 and the secondary tension balancing device 40 to deliver the membrane fibers, ensuring smooth delivery of the membrane fibers from the membrane fiber feeding device 10 to the membrane fiber weaving equipment 50.

[0075] like Figure 7 , Figures 11-12 As shown, in this embodiment, the auxiliary filament feeding device 30 includes a substrate 31, a filament feeding wheel 32, a filament pulley 33, a second transmission assembly 34, and a second drive mechanism 35. Optionally, the substrate 31 is connected to the membrane filament weaving equipment 50, and the filament feeding wheel 32 is provided at the middle position of the substrate 31, while the filament pulley 33 is provided on the side of the substrate 31 facing away from the platform 2. In this way, the membrane filaments passing through the primary tension balancing device 20 can be guided to the filament feeding wheel 32 via the filament pulley 33, and the filaments are fed through the filament feeding wheel 32. Exemplarily, a second guide wheel 301 is also provided on the side of the substrate 31 facing the platform 2, and the membrane filaments passing through the filament pulley 33 are guided to the secondary tension balancing device 40 via the second guide wheel 301.

[0076] Specifically, a second transmission assembly 34 and a second drive mechanism 35 are provided on the substrate 31. The second transmission assembly 34 includes a second driving wheel 341, a second driven wheel 342, and a second belt 343. Specifically, the second drive mechanism 35 includes a motor and a reducer. The output end of the reducer is connected to the second driving wheel 341. The second driven wheel 342 is connected to the second driving wheel 341 via the second belt 343 and is connected to the wire feeding wheel 32. Thus, the second drive mechanism 35 can drive the second transmission assembly 34 to rotate, thereby realizing the rotation of the wire feeding wheel 32 and realizing the wire feeding operation.

[0077] like Figures 7-14 As shown, the membrane fiber weaving device 50 includes a gear 501, an annular rack 502, a second guide rail 503, a second slider 5012, and a rotating platform 55. Specifically, the second guide rail 503 is disposed on the annular rack 502, and both are fixedly connected to the platform 2. The second slider 5012 is disposed on the gear 501 and slidably disposed in the second guide rail 503. The gear 501 and the annular rack 502 mesh with each other. The rotating platform 55 is connected to the second slider 5012. Thus, when the gear 501 moves circumferentially along the annular rack 502, the second slider 5012 moves synchronously with the gear 501, and drives the rotating platform 55 to move relative to the platform 2, thereby realizing the rotation of the membrane fiber weaving device 50 relative to the platform 2 and achieving a weaving effect with the membrane fiber and the weaving thread forming an angle. Exemplarily, in this embodiment, the second guide rail 503 is also configured as an annular structure, and a third driving mechanism 5011 is provided on the gear 501 to drive the gear 501 to rotate.

[0078] Further, the membrane yarn weaving equipment 50 includes a yarn feeding device 51, a knotting device 52, a yarn hooking device 53, a looping device 54, a support beam 56, and an extension beam 57. Specifically, the support beam 56 is mounted on the rotating platform 55, and the extension beam 57 is mounted on the support beam 56. Optionally, the auxiliary yarn feeding device 30 and the secondary tension balancing device 40 are both mounted on the extension beam 57, and the base plate 31 is connected to the extension beam 57, thereby achieving synchronous rotation between the two and the membrane yarn weaving equipment 50. Specifically, the knotting device 52 is fixed to the support beam 56, the yarn feeding device 51 is slidably mounted on the knotting device 52, and the yarn feeding device 51 is used for yarn feeding of the membrane yarn, while the knotting device 52 can knot the membrane yarn and the weaving thread. Further, the yarn hooking device 53 and the looping device 54 are both mounted on the rotating platform 55 for knotting the membrane yarn and the weaving thread. Therefore, when the rotating platform 55 rotates, the weaving device 51, the knotting device 52, the hooking device 53, and the ringing device 54 can all rotate synchronously with the rotating platform 55 relative to the platform 2, thereby realizing the adjustment of the included angle between the membrane filament and the braided thread.

[0079] like Figure 13 and Figure 14As shown, in this embodiment, the fabrication device 51 includes a fabrication guide rail 511, a fabrication slider 512, a fabrication support 513, a third guide wheel 514, and a fabrication wheel 515. Optionally, the fabrication guide rail 511 is mounted on the knotting device 52, the fabrication slider 512 is slidably mounted on the fabrication guide rail 511, one end of the fabrication support 513 is connected to the fabrication slider 512, and the other end is provided with the fabrication wheel 515. Further, the third guide wheel 514 is mounted on the fabrication slider 512, thereby guiding the membrane filaments guided by the secondary tension balancing device 40 to the fabrication wheel 515 via the third guide wheel 514.
