Small bag sticker automatic folding forming device and forming method

Abstract

The invention relates to the technical field of absorbent hygiene products and automatic production equipment manufacture, and discloses an automatic folding forming device for a small package tape. The automatic folding forming device comprises an input unit and a folding unit, wherein the folding unit comprises a folding model, an input wheel, a folding pressure wheel, a folding wheel and an output wheel; the folding model comprises a 90-degree folding module, a folding transition module and a 180-degree folding module; the 90-degree folding module comprises a folding base plane; the input wheel is used for inputting a self-adhesive material input by the input unit to the 90-degree folding module; the folding pressure wheel is used for conducing 90-degree folding on the self-adhesive material on the folding base plane; the 180-degree folding module comprises a folding slit. The invention further discloses the forming method of the automatic folding forming device. According to the invention, the characteristics of the self-adhesive material are fully utilized, and the self-adhesive material of the small package tape is designed according to a preset track and is moved gradually in proper sequence; the automatic folding forming device has the characteristics of small error in folding range, stability, reliability, high practicability and the like.

Description

technical field [0001] The invention relates to the field of absorbent sanitary products and automatic production equipment manufacturing, in particular to an automatic edge folding forming device and forming method for small bag stickers. Background technique [0002] Disposable absorbent products such as sanitary napkins, panty liners, and incontinence pads are mainly composed of a liquid-permeable top layer used in contact with the skin, a liquid-impermeable bottom layer used in non-skin contact, and an absorbent between the liquid-permeable top layer and the liquid-impermeable bottom layer. The core layer and the structural layers such as the wings on both sides. Disposable absorbent products are usually designed in the form of a single package, which is convenient for users to carry with them individually. In order to ensure that single-packaged products avoid contamination when they are carried with them, disposable absorbent products such as sanitary napkins, panty li...

AI Technical Summary

Problems solved by technology

[0005] Guided by a steel rod to fold the edge, the design of the steel rod is more difficult, and because the self-adhesive material has a certain hardness after folding, and the tension of the self-adhesive material is unstable during the production process, it is very difficult It is difficult to design a guide steel rod that meets the ideal requirements

[0006] In addition, the longer the design of the steel bar, the better the hemming effect will be, but the longer it is, it is difficult to carry out effective control in the actual application process, and the hemming error will increase, resulting in the occurrence of substandard products and affecting the yield of the entire production line

[0007] When the folding speed exceeds 150m / min, the stability of the folding is relatively poor, and skewing often occurs, which affects the final use effect
