Roller type melt-blowing receiving web forming device

Abstract

The invention discloses a roller type melt-blowing receiving web-forming device, which is used for receiving fiber yarns sprayed by a melt-blowing die head and forming melt-blowing mesh cloth, and comprises a mounting assembly, a web-forming assembly and a web-forming assembly, the mounting assembly is at least provided with a vertically arranged mounting plane, and the web-forming assembly is arranged on the mounting plane; the roller is used for receiving melt-blown fibers, the roller is horizontally arranged, one end of the roller is rotatably connected with the mounting plane, a plurality of air holes are formed in the surface wall of the roller, and the air holes can generate an air suction trend so that the melt-blown screen cloth can be adsorbed to the surface wall of the roller; the driving assembly is arranged on the mounting assembly, and the driving assembly is used for driving the roller to rotate around the axis of the roller; and the guide roller and the roller are arranged in parallel. The adsorption area has adsorption force on the melt-blown screen cloth, so that the melt-blown screen cloth can be adsorbed on the surface of the roller and is not separated, the adsorption force disappears at the separation part, and separation of the melt-blown screen cloth and the roller is not affected.

Description

technical field [0001] The invention belongs to the field of melt-blown technology, in particular to a roll-type melt-blown receiving web forming device. Background technique [0002] The existing meltblown system mainly includes two types of web forming and receiving methods with their own characteristics. One is to use a mesh belt to receive and form a web, and the other is to use a roller to receive and form a web. Among them, under the same process conditions of the melt-blown die head, the melt-blown cloth formed by the method of receiving and forming the web by the roller is relatively softer and the resistance is relatively smaller. [0003] However, there are certain problems in the use of the existing roller web forming device. The fiber filaments ejected from the general melt-blown die are formed into a web on the upper side of the roller. With the rotation of the roller, the melt-blown mesh will rotate to The lower side of the roller is easy to fall off and separ...

Problems solved by technology

[0003] However, there are certain problems in the use of the existing roller web forming device. The fiber filaments ejected from the general melt-blown die are formed into a web on the upper side of the roller. With the rotation of the roller, the melt-blown mesh will rotate to The lower side of the roller, so under its own gravity, it is easy to fall off and separate from the roller, which will affect the integrity of the melt-blown web
