Problems solved by technology
[0002] At present, the elastic waistbands on the market are basically fixed by hanging or spraying hot melt adhesives. Affected by the amount of glue, the product will be relatively hard, and the normal use of hot melt adhesives needs to be heated, and there will be a certain smell. Hot melt adhesives are still Long-term consumables, now propose a diaper waist elastic forming device

The invention provides a forming device and process for paper diaper waistline rubber bands. The forming device comprises an outer-layer non-woven fabric output device for conveying non-woven fabric rolls, an inner-layer non-woven fabric output device for conveying the non-woven fabric rolls, a rubber band feeding device for pulling out the rubber bands on all rubber band rolls to transversely convey the rubber bands side by side simultaneously at certain intervals, a compositing device and an ultrasonic welding bonding roller; the outer-layer non-woven fabric output device, the rubber band feeding device and the inner-layer non-woven fabric output device convey outer-layer non-woven fabrics, the multiple rubber bands arranged at intervals and inner-layer non-woven fabrics into the compositing device; and the outer-layer non-woven fabrics, the multiple rubber bands and the inner-layer non-woven fabrics which are sequentially arranged from top to bottom are composited through the compositing device and then conveyed into the ultrasonic welding bonding roller to be subjected to welding bonding forming. According to the forming process, using of hot melt adhesives can be avoided, theproduction cost can be lowered, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of diaper production, in particular to a waist elastic forming device for diapers. Background technique [0002] At present, the elastic waistbands on the market are basically fixed by hanging or spraying hot melt adhesives. Affected by the amount of glue, the product will be relatively hard, and the normal use of hot melt adhesives needs to be heated, and there will be a certain smell. Hot melt adhesives are still Long-term consumables, now propose a diaper waist elastic forming device. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a waist elastic forming device for diapers, which can avoid the use of hot melt adhesive, reduce production costs, and improve production efficiency. [0004] In order to achieve the above object, the present invention proposes a diaper waist elastic forming device, which includes an outer layer n...
