Embodiment 1

[0011] Embodiment 1: with reference to attached figure 1 . A production line for elastic and breathable perforated medical bandages, including a PLC controller 9, elastic and breathable casting die forming roller sets 2-1, 2-2 below the elastic polymer resin casting die 1, and multiple pairs of elastic breathable film stretching Roller groups 3-1 and 3-2 are distributed laterally on one side of the forming roller group of the elastic air-permeable casting die, and composite forming roller groups 7-1 and 7-2 are laterally located in multiple pairs of elastic breathable film stretching roller groups. On the side of the film stretching rollers 3-1 and 3-2, the composite nonwoven fabric punching device 10 is located on the side of the composite forming rollers 7-1 and 7-2. The elastic air-permeable casting mold forming roll group 2-1 and 2-2 are composed of a smooth roll 2-1 and a convex knife roll 2-2; the smooth roll 2-1 surface is rigid and the convex knife roll 2-2 is rigid. ...

Embodiment 2

[0012]Embodiment 2: On the basis of Example 1, the elastic air-permeable cast film forming roll set is a negative pressure perforated cast film forming roll set, and the negative pressure perforated cast film forming roll set consists of smooth roll 2-1 and The negative pressure punching roller 2-2 is formed; the roller surface of the negative pressure punching roller 2-2 is covered with negative pressure suction ports, and the negative pressure suction ports pass through the respective flow channels and the negative pressure cavity in the negative pressure punching roller. The negative pressure chamber communicates with the negative pressure suction source through the connecting pipe.

Embodiment 3

[0013] Embodiment 3: On the basis of Embodiment 1, the elastic and air-permeable cast film forming roll set is a cast film forming roll set with concave and convex points perforated.

Abstract

The invention relates to an elastic and breathable perforated medical bandage production line, which, without the use of a hot-press adhesive and without stretching a non-woven fabric, can combine a surface non-woven fabric and a bottom non-woven fabric on two sides of a stretched elastic and breathable film and can conduct secondary perforating forming, and a making method of the production line. The production line comprises a PLC controller, wherein elastic and breathable cast mold-forming roller groups are arranged at the lower side of an elastic polymer resin cast mold head; multiple pairs of elastic and breathable film stretching roller groups are sequentially transversely distributed at the sides of the elastic and breathable cast mold-forming roller groups; composite forming roller groups are transversely arranged at the sides of the elastic and breathable film stretching roller groups, at the tail ends, in the multiple pairs of elastic and breathable film stretching roller groups; and complex non-woven fabric perforating devices are arranged at the sides of the complex forming roller groups. The production line has the following advantages: 1, a medical bandage is good in flatness and good in air permeability; and II, the medical bandage is good in elasticity and good in banding effect.

Description

technical field [0001] The invention relates to an elastic fabric that can combine the surface layer non-woven fabric and the bottom layer non-woven fabric on both sides of the elastic breathable film in a stretched state without hot-pressing glue or stretching the non-woven fabric and forming secondary holes. A breathable perforated medical bandage production line and a production method are mainly used in the production of medical bandages and belong to the field of medical bandage manufacturing. Background technique [0002] CN103417331A, title "thickened non-woven fabric elastic bandage and preparation method", comprising four upper and lower layers of non-woven fabrics, the upper two layers of non-woven fabrics are compounded by dispensing with medical pressure-sensitive adhesive to form the upper double-layer non-woven fabrics, the lower two layers of non-woven fabrics The lower double-layer non-woven fabric is formed by dispensing and compounding the medical pressure-...
