Dust cage type air flow web forming machine

Abstract

The invention provides a dust cage type air flow web forming machine, relating to production equipment of non-woven fabrics. The dust cage type air flow web forming machine comprises a frame, wherein a Venturi pipe with a small-top large-bottom section shape is connected in the frame; a cylinder and an air inlet are arranged at the upper end of the Venturi pipe; one side of the cylinder is provided with an input curtain; a pair of rollers are arranged between the input curtain and the cylinder; a dust cage and a cotton pressing roller are arranged at the lower end of the Venturi pipe; one side of the dust cage is provided with an air suction pipe; and the output side of the dust cage is provided with an output curtain. The dust cage type air flow web forming machine also comprises a layering prevention device, wherein the layering prevention device comprises a transmission shaft which is arranged laterally; the transmission shaft is arranged in the Venturi pipe; the periphery of the transmission shaft in the Venturi pipe is connected with blades; two ends of the transmission shaft are separately supported on the frame through a bearing and a bearing seat; and one end of the transmission shaft is connected with a transmission device. By using the dust cage type air flow web forming machine, the layering problem in the web forming process by mixing different properties of fibers is solved, and the raw material adaptability and machine performance of the dust cage type web forming machine are improved, thus the dust cage type air flow web forming machine has important practical significance in production of thick and heavy non-woven felt and mat products.

Description

technical field [0001] The invention relates to nonwoven production equipment, in particular to the structure of a dust cage air-laid machine. Background technique [0002] Dust cage air-laid machine is an important equipment for the production of heavy non-woven fiber mats and mats, especially suitable for various waste recycling and the formation of special fibers that are difficult or unsuitable for carding, such as cotton, hemp, bristle, coconut And glass fiber, carbon fiber, basalt fiber and stainless steel fiber, etc. [0003] The basic principle structure of the dust cage airlaid machine is as follows: figure 1 shown. Its working process is: the fiber raw material that has been loosened and mixed is sent from the input curtain 1, held and fed by a pair of rollers 2, and is finely torn, grasped, and stripped by the high-speed rotating cylinder 3 needle teeth into a nearly single It is fibrous, and then flies away from the cylinder under the action of centrifugal for...
