[0002] In the existing nursing pads for disposable absorbent products, the composite bottom film is pre-composited before being put on the machine. The composite bottom film is usually made of PE film and non-woven fabric. The softness and heat shrinkage of the two non-woven materials are different. The tension adjustment device for each layer of material is not uniformly adjusted during compounding, and the bonding pressure of each layer of material is insufficient when bonding. In the end, cracking often occurs, and serious leakage of the composite membrane will occur. The root cause of the leakage of the composite membrane is that the tension of each layer of the composite membrane material is not uniform when the composite membrane material is compounded, and the adhesion of each layer of material when the materials are bonded is not uniform. lack of pressure

Embodiment Construction
[0028] Refer to attached figure 1 , the non-woven fabric 100 on the left non-woven fabric roll enters the automatic tensioning device 5 through the automatic material changer 2 and is stretched and flattened. If the non-woven fabric is broken, the broken material monitor 3 can find out in time And shut down, send alarm sound simultaneously, when the non-woven fabric 100 on the left non-woven fabric roll 1 is nearly used up, the non-woven fabric 100 on the right non-woven fabric roll 4 can be automatically with the left on the automatic material changer. The non-woven fabric 100 on the non-woven fabric roll 1 is connected to complete the automatic material change.
[0029] The automatic tensioning device 5 is a traditional material tensioning system. The non-woven fabric 100 is stretched and flattened on the automatic tensioning device 5, and then enters the automatic deviation correction device 6. The main function of the automatic deviation correction device 6 is to make the ...

The invention relates to the field of health and care products, and in particular relates to a device for applying a bottom-layer compound film of a disposable absorbing product nursing pad. The bottom compound film is manufactured when the nursing pad is produced; in the tensioning way of a traditional material, a set of compound tensioning rollers with the arc surfaces is additionally arranged; a plurality of arc-shaped movable roll surfaces are arranged on the surfaces of the compound tensioning rollers, so that the tension can be adjusted again in the material compounding process and is enabled to be even; a set of movable drum-shaped press rollers is additionally arranged. After the device is adopted, the phenomenon of leakage of the compound film caused by the frequent uneven material tension of the compound film in the compound film manufacturing process can be eliminated, and the bottom compound film of the nursing pad can be formed by compounding two layers or a plurality of layers of material when the nursing pad is manufactured and is applied to be taken as the bottom layer of the nursing pad.
Description
technical field [0001] The invention relates to the field of sanitation and nursing products, and relates to a device for applying a composite base film for nursing pads of disposable absorbent products. The device can eliminate the leakage phenomenon that often occurs in the production of composite films, and can be used in the production of nursing pads. Simultaneously compound two-layer and multi-layer materials to form a composite bottom film, and apply it as the bottom layer of the nursing pad. Background technique [0002] In the existing nursing pads for disposable absorbent products, the composite bottom film is pre-composited before being put on the machine. The composite bottom film is usually made of PE film and non-woven fabric. The softness and heat shrinkage of the two non-woven materials are different. The tension adjustment device for each layer of material is not uniformly adjusted during compounding, and the bonding pressure of each layer of material is ins...
