Embodiment Construction

[0026] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] refer to Figure 1 to Figure 4, the present embodiment provides an elastic sheet, comprising an upper substrate 1, a lower substrate 2 and an elastic film 3 clamped between the upper substrate 1 and the lower substrate 2, the upper substrate 1, the lower substrate Material 2 is an air-permeable sheet material, and non-woven fabric material is selected in this scheme. The upper base material 1, the elastic film 3, and the lower base material 2 are fixed through a plurality of connecting parts to form fastening points 4, and each fastening point 4 is distributed to form a plurality of partition lines F, and each partition line F is spaced along the lateral direction. Set, two adjacent partition lines F form a partition area 5, there is at least one cutting unit 6 in the adjacent two partition lines, and each cutting unit 6 includes a strip-shap...

Abstract

The invention relates to the field of disposable hygienic products, in particular to an elastic sheet manufacturing device which comprises a rack, an elastic film unwinding mechanism, a low-speed driving roller, a high-speed driving roller, a compounding station, an ultrasonic device, a middle driving roller, a cutting device, a tension buffering mechanism and an output driving roller, and the elastic film unwinding mechanism, the low-speed driving roller, the high-speed driving roller, the compounding station, the ultrasonic device, the middle driving roller, the cutting device, the tension buffering mechanism and the output driving roller are arranged on the rack according to an assembly line. An upper base material conveying mechanism and a lower base material conveying mechanism are arranged on the rack and located at the compounding station, a plurality of welding point positions are arranged on the ultrasonic device, a partition line is formed by the welding point positions, the included angle between the projection of the partition line on the horizontal plane and the advancing direction of the assembly line is 25-35 degrees, and the cutting device is provided with a plurality of cutting parts used for forming cutting units on the sheets. The technical problem that an elastic sheet manufacturing device which is good in breathability and comfortable to wear does not exist in the field of existing disposable hygienic products is solved.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to an elastic sheet manufacturing device. Background technique [0002] At present, the application of elastic non-woven fabrics has been widely used, especially in the field of disposable sanitary products. Its structure is such as the composite elastic non-woven fabric structure disclosed in Chinese patent application number: CN201210380277.2 The composite elastic non-woven fabric structure includes an elastic fabric layer and a non-woven fabric layer. The non-woven fabric layer is integrated with the elastic fabric layer. And the manufacturing method of the composite elastic non-woven fabric includes: providing an elastic fabric layer; combining a non-woven fabric layer with the elastic fabric layer; heat pressing the non-woven fabric layer and the elastic fabric layer to make them flat; and cooling the non-woven fabric layer and the elastic fabric layer Floor. By v...
