Problems solved by technology

[0004] The common disadvantages of the above-mentioned background technologies: one is that it is impossible to form three-dimensional three-dimensional hole grooves on both sides of the non-woven fabric, so the perforated non-woven fabric not only has a small liquid storage capacity, but also cannot solve the problem of side leakage, thus The surface of the perforated non-woven fabric cannot form a dry surface, which makes people's skin feel very uncomfortable; secondly, due to the influence of the size of the coil, continuous punching operations cannot be formed, and the material needs to be replaced separately

Embodiment 1

[0018] Embodiment 1: with reference to attached Figure 1-8 . A three-dimensional punching mechanism for disposable sanitary materials, which includes a PLC controller 1, a first unwinding material roller 2, a tension control mechanism 3, a pressing material cutting and splicing mechanism 4, a second unwinding material roller 5, a correction device 6, Three-dimensional three-dimensional punching mechanism 7 and winding mechanism 8, described pressing material cutting splicing mechanism 4 is made of two sets of pressing material cutting devices with the same structure and a set of splicing devices, the first pressing material cutting device is composed of pressing plate 401, pressing Material cylinder 402, elastic cutter press plate structure 403, cutting cylinder 405 and groove cutter plate 407 are formed, the press plate 401 is composed of an upper plate and a lower plate, the upper plate is connected with the press cylinder 402, and the lower plate is fixed on the frame Up ...

Embodiment 2

[0020] Embodiment 2: On the basis of Embodiment 1, the perforated concave roller 702 and the perforated convex roller 703 are distributed up and down, that is, the perforated concave roller 702 is on the bottom and the perforated convex roller 703 is on the top, or the perforated concave roller 702 is on, punching convex roll 703 is down.

Embodiment 3

[0021] Embodiment 3: on the basis of embodiment 1, with reference to appended Figure 8 . Three-dimensional three-dimensional punching method for disposable hygienic materials, (1) the non-woven fabric splicing cloth head on the second unwinding material roller 5 is glued with double-sided adhesive tape and is located on the fixing plate 410 of the pressing device of the pressing cutting and splicing mechanism 4 Standby with the movable plate 409, at this time, the pressure cylinder 402 in the second pressure material cutting device compresses the spare non-woven fabric coil through the pressure plate 401 under the PLC command; The spun fabric roll enters the three-dimensional punching mechanism 7 through the pressing material cutting and splicing mechanism 4, the tension control mechanism 3, and the knitting device 6, and passes through the traction roller 704 to the convex-concave extrusion punching of the punching concave roller 702 and the punching convex roller 703. Afte...

Abstract

The invention relates to a three-dimensional punching mechanism and a punching method of a disposable sanitary material. An air-draft shaping roll, a concave punching roll and a dragging roll are arranged in a linear shape, a convex punching roll is matched with the concave punching roll and positioned on the concave punching roll, electric heating pipes are positioned in the convex punching roll, the concave punching roll and the dragging roll which are supplied with power by conducting slide rings positioned at the ends of the electric heating pipes, plate type thermocouples are positioned in the convex punching roll, the concave punching roll and the dragging roll and are supplied with the power by conducting rings, and the electric heating pipes are controlled to work by a PLC (Programmable Logic Controller). The three-dimensional punching mechanism has the advantages that firstly, the mechanism can press the original flat non-woven fabric raw material into products with double-side three-dimensional through holes so that the thickness of the non-woven fabric raw material is increased by 20-30 times after punching and stretching; and secondly, the mechanism realizes point type contact of sanitary article surfaces and skin of human bodies, a formed three-dimensional through hole liquid storage tank has large storage capacity of menstrual liquid and urine without side leakage so that the skin of people still keeps dry and comfortable, and the comfortableness of the product is greatly improved.

Description

technical field [0001] The invention relates to a three-dimensional perforated surface capable of forming a three-dimensional structure on both sides of the non-woven fabric perforated, so as to achieve a large liquid storage capacity, prevent side leakage, and point contact. A three-dimensional three-dimensional punching mechanism and punching holes for disposable sanitary materials The method belongs to the field of manufacturing a non-woven fabric punching mechanism. Background technique [0002] CN101688344A, title "Non-woven Fabric Punching Mechanism and Method, and Non-woven Fabric Manufactured by the Same", the said mechanism and method are economical and cost-effective. The invention also discloses the non-woven fabric manufactured by using the mechanism and method. The non-woven fabric punching mechanism includes a first roller with a plurality of needles on the outer peripheral surface, and two or more second rollers rotating relative to the outer peripheral surfa...
