Once formed composite production device for various melt-blown filter materials

Abstract

The invention relates to a production device for non-woven cloth, in particular to a once formed composite production device for various melt-blown filter materials. The device comprises screw extruders, spray heads, an air supply device, a receiving net, an air suction device, a reciprocating vehicle capable of transversely moving to and fro, a cloth pressing roller, a balanced tension winding roller and an electret rack, wherein the number of the screw extruders is at least two, outlets of the screw extruders are connected with the spray head respectively, an outlet of the air supply device is connected with the spray head through a pipe, the receiving net is arranged on the reciprocating vehicle capable of transversely moving to and fro, the spray heads are arranged at the outside of the receiving net respectively, the inside of the receiving net corresponding to a close part of melt-blown fibers sprayed by the spray head is provided with the air suction device, the reciprocating vehicle is provided with the balanced tension winding roller matched with the receiving net and driven by a motor, and the adjustable cloth pressing roller is arranged between the balanced tension winding roller and the receiving net; and the outside of the receiving net close to the spray head is provided with the electret rack which is provided with a plurality of groups of high-pressure discharge brushes, and the reciprocating vehicle is arranged on a track which is grounded.

Description

Technical field [0001] The invention relates to a non-woven fabric production equipment, in particular to a one-time molding composite production equipment for multiple melt-blown filter materials. Background technique [0002] Usually melt blown filter cloth production equipment adopts a single screw extruder through a single nozzle connected to the outlet of the screw extruder and an air supply device matched with the nozzle, and a single melt blown raw material is sprayed on the receiving device through the nozzle and the air supply device. The melt blown filter cloth of a single melt blown filter material is formed on the Internet. If the melt blown filter cloth of different materials needs to be compounded, it must be compounded by a special filter cloth compounding machine. The compounding process is relatively complicated, the equipment investment is large, and the same material cannot be guaranteed to be melted during the compounding process. The intact and organic combin...
