Problems solved by technology

The hollow fiber membrane has a high packing density when it is made into a membrane module, but due to the general mechanical properties of the membrane, it is easy to be entangled, knotted, and broken during the spinning process of the fiber filament, which affects the filtration of the hollow fiber membrane produced in the subsequent production. efficiency

Embodiment 1

[0047] See Figure 1 to Figure 7 The present invention provides a hollow fiber membrane spinning and winding device, comprising a winding station arranged in sequence for winding the filaments, and a winding station for sending the wound filaments away from the winding station. The transfer station, the detection station used to detect the coiled filaments;

[0048] The rewinding station includes a mirror-symmetrical rewinding plate 100,

[0049] The rewinding board 100 is connected with

[0050] first power source 101,

[0051] The take-up roller 102 driven by the first power source 101,

[0052] the second power source 103,

[0053] Driven by the second power source 103, located above the take-up roller 102, the pinch roller 104 with the spiral groove 1041,

[0054] Tensioning roller 105, the tensioning roller 105 is used to cooperate with the pressing roller 104 to tension the filaments;

[0055] Below the pressing roller 104, there is a pressing block 106 that moves ...

Embodiment 2

[0061] See Figure 1 to Figure 7 The difference between this embodiment and Embodiment 1 is that the pinch roller 104 is connected with the first rack workpiece 107, the tension roller 105 is connected with the second rack workpiece 108, the first rack workpiece 107 and the second rack workpiece 107 A fixed gear 109 is engaged between the bar workpieces 108 .

[0062] When the winding roller 102 is not being wound, the pressing roller 104 is not driven by the second power source 103, and the first rack workpiece 107, the second rack workpiece 108, and the fixed gear 109 maintain a relatively static and stable state. The first rack workpiece 107 and the second rack workpiece 108 can be displaced in opposite directions by means of the fixed gear 109 .

[0063] When the winding roller 102 is continuously wound, its diameter gradually increases. The fiber filaments whose diameters gradually increase slowly lift the pressing block 106 to displace upward, and the pressing block 10...

Embodiment 3

[0068] See Figure 1 to Figure 7 The difference between this embodiment and Embodiment 1 is that the helical groove 1041 is a crossed double helical groove. The intersecting spiral grooves 1041 are communicated near both ends of the pressing roller 104 to ensure that the pressing block 106 can move back and forth.

[0069] In this embodiment, the top of the pressing block 106 is a protruding shuttle 1061 . The pressing block 106 passes through the shuttle-shaped member 1061 protruding from the top. When the pressing roller 104 rotates, the helical groove 1041 can be adapted to the shuttle-shaped member 1061 to rotate, and then the pressing block 106 with the shuttle-shaped member 1061 can perform a reciprocating straight line. Movement, guiding the newly wound fiber yarn, with a high degree of automation.

[0070] At the same time, the maximum length of the shuttle 1061 is longer than the intersecting gap length of the helical grooves 1041, so as to prevent the shuttle 1061 ...

Abstract

The invention relates to the technical field of spinning and winding, in particular to a hollow fiber membrane spinning and winding device and a winding process thereof, including a winding station, a transfer station and a detection station arranged in sequence; the winding station includes The mirror-symmetric winding plate is connected with a first power source, a winding roller, a second power source, a pressing roller, and a tensioning roller; A compression block that guides the fiber filaments. The invention is cleverly designed and has a high degree of automation. There is a winding station, which is equipped with a reciprocating movement along the spiral groove, which can continuously guide the fiber yarn in an orderly manner during the winding process, so that the fiber yarn is evenly wound, not easy to be entangled and knotted, and strengthens the subsequent film formation. mechanical properties.

Description

technical field [0001] The invention relates to the technical field of hollow fiber membrane spinning and winding, in particular to a hollow fiber membrane spinning and winding device and a winding process thereof. Background technique [0002] Hemodialysis is the main method for treating patients with acute and chronic renal failure, and hemodialysis membrane is very important in hemodialysis products. The purpose of hemodialysis is to replace some of the functions lost in renal failure, such as removing metabolic waste and regulating water, electrolyte and acid-base balance. Its basic principles include mechanisms such as dispersion, osmosis, convection and ultrafiltration to remove harmful substances in the body. The exchange of solute and water during dialysis constitutes the theoretical basis for removing toxins, removing water and supplementing necessary substances during hemodialysis. [0003] Dialysis membrane material is a key factor affecting the therapeutic effe...
