Perforating and embossing forming mold

Abstract

The invention discloses a perforating and embossing forming mold, which is composed of a concave and convex roller pair; the concave and convex rollers are mutually meshed, wherein perforating needle regions and counter bore regions, which are mutually spaced from each other, are arranged on the surface of the convex roller; convex regions and concave hole regions, which are mutually spaced from each other, are arranged on the surface of the concave roller; bumps on the concave roller correspond to concave holes on the convex roller; concave holes on the concave roller correspond to perforating needles on the convex roller; and both the convex roller and the concave roller are provided with heating devices. The forming mold disclosed by the invention achieves synchronous implementation of perforating and embossing and simplifies processing. A perforated and embossed product, which is produced by the perforating and embossing forming mold, has perforating and embossing regions, and the perforating and embossing regions are mutually spaced, so that a contact area with a human body is reduced through the distribution of the embossing regions, and meanwhile liquid infiltration is accelerated by virtue of the perforating regions; therefore, the forming mold is dyer and more comfortable.

Description

technical field [0001] The invention relates to a mold for punching and embossing non-woven fabrics and film rolls. Background technique [0002] Perforated and embossed non-woven fabrics or films are widely used in the fields of sanitary products and medical supplies, such as sanitary napkins, diapers, etc. The perforated and embossed three-dimensional non-woven fabrics or films have a three-dimensional structure, and the contact area with the skin Less, leading in the market. However, at present, there are relatively few three-dimensional non-woven fabrics or films with both perforated and embossed structures. After the holes are punched in a punching machine, it is sent to the embossing roller for embossing. However, due to the certain distance between the machines, the non-woven fabric will deviate during the conveying process, so that the punched holes and the extruded The patterns cannot be better aligned, resulting in an unattractive appearance after the finished pr...

However, at present, there are relatively few three-dimensional non-woven fabrics or films with both perforated and embossed structures. After the holes are punched in a punching machine, it is sent to the embossing roller for embossing. However, due to the certain distance between the machines, the non-woven fabric will deviate during the conveying process, so that the punched holes and the extruded The pattern can not be better aligned, resulting in unsightly appearance of the finished product

Although the invention patent CN201210066490.6 discloses a non-woven fabric punching machine, including convex tooth rollers, concave tooth rollers and embossing rollers, to achieve continuous production of punching and embossing, but because it is punched first and then Embossing cannot be guaranteed to be carried out at the same time. During the punching process, the position deviation of embossing and punching will also occur due to the stretching of the non-woven fabric. It is difficult to achieve precise positioning, and the three rollers are not easy to adjust and control, and the operation is complicated.
