Description

Technical Field

[0001] The utility model relates to the technical field of hollow fiber membrane production devices, and particularly relates to a hollow fiber membrane winding device. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It mainly uses a bundle of hollow fiber membranes arranged in a dialyzer. Relying on the semi-permeable membrane principle, through diffusion, convection and other methods, various harmful or redundant metabolic wastes and excessive electrolytes in the patient's blood are removed from the body, so as to achieve the purpose of purifying the blood and correcting the water and electrolyte and acid-base balance; during the production process of the bundle of hollow fiber membranes, the membrane filaments continuously produced by the membrane filament production device are collected on the wire collecting rack by a winding device, and then form a bundle of hollow fiber membranes after steps such as wrapping and cutting.

[0003] However, in the prior art during the winding process, when the wire collecting rack for collecting the membrane filaments is full, the worker must quickly complete the operation of replacing the empty rack, that is, the full wire collecting rack needs to be removed and an empty wire collecting rack needs to be replaced at the same time. The labor intensity of this process is relatively large and the proficiency requirement for the worker is high, resulting in low production efficiency. And because during the process of replacing the wire collecting rack, the membrane filaments are in a continuous production state all the time, the membrane filaments produced during the replacement of the wire collecting rack cannot be wound on the new empty wire collecting rack. Therefore, these membrane filaments will be cut off and treated as waste filaments. As a result, raw material waste will be caused, leading to an increase in the manufacturing cost of the product. At the same time, the cut-off membrane filaments are very difficult to collect and handle under the interference of factors such as static electricity, resulting in a messy site for the entire replacement of the empty rack. In summary, those skilled in the art urgently need to solve the above technical problems. Summary of the Utility Model

[0028] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the specific embodiments cited are not intended to limit the present utility model.

[0029] Embodiment, referring to Figures 1 to 7 As shown, a hollow fiber membrane winding device includes a first winding mechanism, a second winding mechanism, and a wire splitting and guiding mechanism, all of which are installed on the frame 10.

[0030] The first winding mechanism includes a first drive shaft 23 and a first power source 25 for driving the first drive shaft 23 to rotate. One end of the first drive shaft 23 is installed with a detachable first wire winding frame 30; the second winding mechanism includes a second drive shaft and a second power source for driving the second drive shaft to rotate. One end of the second drive shaft is installed with a detachable second wire winding frame 40; the frame 10 is in the shape of a vertically arranged cuboid, and both the first wire winding frame 30 and the second wire winding frame 40 are used for winding membrane filaments and are respectively arranged on both sides of the frame 10; and a footrest 11 for replacing the wire winding frame is provided on each side of the frame 10.

[0031] The wire splitting and guiding mechanism includes a transverse movement driving component 51 and a wire splitting component 52 installed on the transverse movement driving component 51. The transverse movement driving component 51 drives the wire splitting component 52 to move between the first wire winding frame 30 and the second wire winding frame 40. The film wire passes through the wire splitting component 52 and is wound on the first wire winding frame 30 or the second wire winding frame 40. The wire splitting component 52 guides and splits the film wire during the winding process. Through the setting of the double wire winding frames and the wire splitting and guiding mechanism, the present utility model can continuously and alternately wind the wire. That is, when one of the wire winding frames is full, the wire splitting and guiding mechanism drives the film wire to the opposite wire winding frame to continue winding, so that the film wire can be continuously wound during the winding process, reducing raw material waste and improving production efficiency.

[0032] In a specific embodiment, referring to Figures 1 to 5 As shown, the structures of the first winding mechanism and the second winding mechanism are completely the same and are both installed inside the frame 10. Only the outer ends of the driving shafts extend outwards from the frame 10. Taking the structure of the first winding mechanism as an example, the first driving shaft 23 is horizontally rotatably installed on the bottom plate 21 fixed to the frame 10 through a bearing seat 22, and one end of the first driving shaft 23 extends to the outside of the frame 10 and is used to install the first wire winding frame 30. The first power source 25 is installed inside the frame 10, and the first power source 25 drives the first driving shaft 23 to rotate through the first synchronous belt 24. A disk-shaped base 26 is coaxially fixed on the first driving shaft 23. The base 26 is located outside the frame 10. A positioning hole 261 for installing the first wire winding frame 30 is provided on the outer end surface of the base 26. An annular electromagnet 262 is fixed outside the base 26. The electromagnet 262 is electrically connected to a conductive slip ring 27 installed on the first driving shaft 23. The conductive slip ring 27 is connected to an external power supply, and then power is supplied to the rotating electromagnet 262 through the conductive slip ring 27. In this embodiment, a magnet attracting plate 32 and a plurality of positioning pins 31 are fixed on the central disk 33 of the first wire winding frame 30. When the first wire winding frame 30 is coaxially sleeved on the first driving shaft 23 through its central disk 33, the positioning pins 31 on the central disk 33 are correspondingly and fittingly inserted into the positioning holes 261 on the base 26. At the same time, the electromagnet 262 on the base 26 is energized to generate a magnetic attraction force to attract the magnet attracting plate 32 on the central disk 33, thereby realizing the circumferential positioning and axial positioning of the first wire winding frame 30 sleeved on the first driving shaft 23, so that the first wire winding frame 30 can rotate synchronously with the first driving shaft 23. The wire winding frame of the present utility model is installed on the driving shaft in the form of a combination of positioning pins 31 and an electromagnet 262, with a simple structure, easy operation, and convenient loading and unloading. A counting induction block 28 is also installed on the first driving shaft 23. The counting induction block 28 is used in cooperation with a photoelectric sensor 29 installed on the bottom plate 21 to record the number of turns of the first driving shaft 23.

[0033] In a specific embodiment, referring toFigures 1 to 3 and Figures 6 to 7 As shown in Figures 6 to 7 , the transverse movement driving assembly 51 is a magnetic coupling rodless cylinder horizontally installed at the end of the frame 10. The wire splitting assembly 52 is installed on the driving block of the magnetic coupling rodless cylinder. The magnetic coupling rodless cylinder drives the wire splitting assembly 52 to move horizontally back and forth. The wire splitting assembly 52 includes a support 521 installed on the driving block of the magnetic coupling rodless cylinder, multiple horizontal wire splitting needles 523 installed on the support 521, and multiple vertical wire splitting needles 522 installed on the support 521. The vertical wire splitting needles 522 are vertically arranged and equally spaced along the horizontal direction. Both ends of the vertical wire splitting needles 522 are installed on two mounting seats 5221 both fixed to the support 521. The horizontal wire splitting needles 523 are horizontally arranged and equally spaced along the vertical direction. A mounting ring 5231 coaxially sleeved on a rotating shaft 524 is fixed at the fixed end of each horizontal wire splitting needle 523. The mounting rings 5231 of all the horizontal wire splitting needles 523 are adjacent and closely attached in sequence. Two positioning sleeves 525 are also sleeved on the rotating shaft 524. Locking nuts 527 are provided at both ends of the rotating shaft 524 and are connected by threads. All the mounting rings 5231 are clamped by the locking nuts 527 and the positioning sleeves 525. Among them, the upper positioning sleeve 525 and the locking nut 527 are clamped on a fixed block 526 fixed above the support 521, and the lower positioning sleeve 525 passes through the fixed block 526 fixed below the support 521, which is convenient for adjusting the spacing, quantity and height position of the horizontal wire splitting needles 523.

[0034] During use, the film filaments pass through between two adjacent vertical wire splitting needles 522 and two adjacent horizontal wire splitting needles 523 in sequence and then wind around the first wire collecting frame 30 or the second wire collecting frame 40. Through the multiple horizontal wire splitting needles 523 and the multiple fine wire splitting needles, the film filaments can be orderly gathered and grouped, ensuring that the film filaments are grouped to a suitable width and thickness, and ensuring that the film filaments will not cross and get disordered during the process of replacing the wire collecting frame.

After the membrane wire passes through the wire-dividing assembly 52, it passes through the static removal area of ​​the vertical electrostatic rod 71 and the static removal area of ​​the horizontal electrostatic rod 72 respectively. The vertical electrostatic rod 71 and the horizontal electrostatic rod 72 are both used to alternately act on the coupled electrode needles through AC high voltage, and the AC implementation method is used to act on the electrode needles through coupling devices to generate corona discharge, ionize air molecules, generate a large number of positive and negative air ions, and transport them to the surface of the electrostatic object through compressed air, neutralize the positive and negative electrostatic charges, and achieve efficient and reliable elimination of static electricity on the surface of the object. The membrane wire passing through the wire-dividing assembly 52 is destaticized by the vertical electrostatic rod 71 and the horizontal electrostatic rod 72, and the interference of static electricity on the winding process of the membrane wire is avoided as much as possible to ensure the winding quality.

[0036] In a specific embodiment, referring to Figures 1 to 3 As shown, both sides of the frame 10 are also installed with a wire suction assembly, which includes a wire guide tube 61 fixed on the frame 10 and a pneumatic conveyor 62 installed on one end of the wire guide tube 61, the pneumatic conveyor 62 is used to introduce the membrane yarn passing through the wire separation assembly 52 into the wire guide tube 61, and both sides of the frame 10 are also installed with a wire guide fork 81, the wire guide fork 81 is U-shaped and its opening is horizontally facing away from the frame 10. When the winding device is temporarily unable to rewind normally due to maintenance or other reasons, the membrane yarn can be introduced into the wire guide tube 61 through the pneumatic conveyor 62, and the membrane yarn is guided by the wire guide fork 81 in this process. A collection box for collecting membrane yarn is placed at the other end of the wire guide tube 61 to ensure uninterrupted production and orderly collection of waste yarn, and to ensure that the wire collection site is neat and orderly.
