[0002] In neurosurgery, neurosurgery pad (brain cotton piece) as an important medical consumables, need to have softness, liquid absorption and biocompatibility and other characteristics.Fiber line is the core raw material of neurosurgery pad production and processing.

[0003] However, the existing fiber line feeding mechanism has significant defects in actual application: fiber line is prone to breakage during high-speed traction due to tension fluctuation or instantaneous overload, resulting in frequent shutdown of production line, which seriously affects production efficiency and product yield.Especially when multiple fiber lines are processed in parallel, the traditional fixed tension adjusting device cannot realize independent dynamic compensation of each line, and the difference in line diameter or traction speed will exacerbate tension imbalance, further increasing the risk of line breakage.In addition, the conventional overline structure is fixed in aperture and has sharp edges, which can easily cause fiber line surface wear and even fuzz, affecting the clinical use safety of neurosurgery pad.

[0028] In the preferred scheme, the tension mechanism support 5 is detachably installed on the top surface one side of the bottom plate 1.

[0030] In the preferred scheme, the number of partitions provided in the tension mechanism mounting seat 6 is the same as the number of a single group of wire cylinder columns 4.

[0031] In the preferred scheme, the tension mechanism 7 includes an I-shaped movable piece 9, the I-shaped movable piece 9 is composed of two wing plates 902 and a web plate 901 between the two wing plates 902, and a guide rod 10 vertically penetrating the wing plate 902 is arranged in the partition.

[0032] The second wire passing hole 12 is arranged on the web plate 901.

[0033] In a preferred embodiment, two I-shaped movable members 9 are arranged in each of the compartments, and springs 11 are arranged on the guide rods 10 above the top flanges 902 of the upper I-shaped movable members 9 and on the guide rods 10 below the bottom flanges 902 of the lower I-shaped movable members 9.

[0034] In a preferred embodiment, a group of guide rods 8 is arranged on each side of the mechanism support 5, and each guide rod 8 is provided with two first wire passing holes 801.

[0035] The number of the guide rods 8 in each group is equal to the number of the compartments, and each group of guide rods 8 is arranged on the same vertical plane.

[0036] The fiber wires pass through the guide rods 8 arranged on both sides of the mechanism support 5.

[0037] In a preferred embodiment, the first wire passing holes 801 and the second wire passing holes 12 are variable-diameter holes, and the diameters of the holes gradually increase from the center to the two ends, and the walls of the first wire passing holes 801 and the second wire passing holes 12 are arc-shaped.

[0038] As shown in FIGS.
