Staple fiber delivery mechanism for melt blown nonwoven cloth processor

Abstract

A short fiber transportation mechanism of a melting blow nonwoven cloth processing machine belongs to the nonwoven machinery technology field, comprising a box body, a wool carding roller, an airflowgroove, a backup plate and a cotton driving roller. The mechanism is characterized in that an airflow cover is extendedly arranged on the upper part of the airflow groove, the top center of the airflow cover is funneled into an air inlet, the lower part of the airflow groove extends to the lower part of a working platform and forms a further flatly shrunk cotton spraying tube; the cotton driving roller is connected onto the outer wall of the lengthwise corresponding box wall of the box body; the carding roller is inserted into the airflow groove. The mechanism has the advantages that the cotton driving roller can be adapted to driving thickness-varied short fiber cotton blankets; the airflow carrying short fiber can be guaranteed to be sprayed out from the cotton spraying tube which extends to the lower part of the working platform and corresponds to a melted extrusion structure, and brought together with the hot melted fibers extruded by the melted extrusion machine to conglutinate into a melting blow fiber layer.

Description

Technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a short fiber conveying mechanism of a melt-blown non-woven fabric processing machine, which is used to cooperate with the melt-extrusion mechanism and a composite forming mechanism of the melt-blown non-woven fabric processing machine to process Meltblown non-woven fabric finished product. Background technique [0002] Melt-blown non-woven fabric is a non-woven product first developed by foreign countries. It consists of two thin layers of non-woven fiber cloth layers rich in pores and the non-woven fiber cloth layer between the non-woven fiber cloth layers. The fiber layer (usually called melt-blown fiber layer) containing hot-melt bonding fibers is composed of a sandwich structure. This kind of meltblown non-woven fabric product has excellent compressibility and recoverability when compressed in the thickness direction. As a whole, it has the ultimate bulki...

AI Technical Summary

Problems solved by technology

However, there is no successful self-made equipment for processing melt-blown non-woven fabrics in my country so far, and because foreign companies have not exported equipment in order to ensure the advantages of melt-blown non-woven products in the Chinese market, even in the literature such as US Patent US5508102 , US4931355, US4755178, US4623576, US4604313, etc. have very limited disclosure of complete sets of melt-blown non-woven equipment. Therefore, the melt-blown non-woven fabrics used by clothing and bedding manufacturers in my country can only rely on imports. Affected by price constraints, it loses the market competitiveness of the final product
