Piece missing preventing device for disposable hygienic product production and using method of piece missing preventing device

Abstract

The invention relates to the technical field of the disposable hygienic product industry, in particular to a piece missing preventing device for disposable hygienic product production and a using method of the piece missing preventing device. The piece missing preventing device comprises a core body cut-off mechanism and a mesh belt driving unit, wherein a core body not-cut-off front negative pressure groove is formed in the right side of the core body cut-off mechanism, and a core body cut-off rear negative pressure groove is formed in the left side of the core body cut-off mechanism; and a piece missing preventing reverse negative pressure groove is formed in the upper side of the core body cut-off rear negative pressure groove, and the mesh belt driving unit is arranged on the upper right portion of the piece missing preventing reverse negative pressure groove. According to the piece missing preventing device for disposable hygienic product production and the using method of the piece missing preventing device, a piece missing preventing method being simple in structure, convenient in equipment installation, adjustment and maintenance, capable of being used for disposable hygienic products at high speed and continuously is arranged; and the invention provides the piece missing preventing method for the disposable hygienic products, and stable airflow and air pressure are used for controlling factors such as piece missing and piece lack of various materials in the conveying process, so that the unstable characteristic in the transferring process is effectively controlled,and then high-speed and high-quality production efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of the disposable sanitary product industry, in particular to a leakage prevention device for the production of disposable sanitary products and a method for using the same.
