Meltblown composite production device formed by one-step molding

Abstract

A meltblown composite production device formed by one-step molding relates to a production device of the nonwoven fabric, in particular to a composite production device formed by one-step molding of multiple meltblown filter materials. The production device comprises a rack, an automatic feeding device, screw extruders, spray nozzles, an air supply device, a receiving net, a suction device, a reciprocating trolley which can perform transverse reciprocating motion, a cloth-pressing roller, a balanced tension winding roller, an electret rack and a screw extruder automatic lift device, wherein the automatic feeding device contains a bin, a feeding pipe, a charging cylinder, a suction fan, a filter screen and a hopper; the number of the screw extruders is at least two, the outlets of the screw extruders are separately connected with spray nozzles; the spray nozzles are arranged on the outside of the receiving net, the inside of the receiving net, close to the position of meltblown fibers sprayed by the spray nozzles is provided with the suction device; the outside of the receiving net, close to the spray nozzles is provided with the electret rack, the receiving net is arranged on the reciprocating trolley; and the screw extruder automatic lift device contains a lifting drive motor, a speed reducer, a driving gear, a lifting screw, a guide post and a guide sleeve.

Description

technical field [0001] The one-time molding melt-blown compound production equipment of the present invention relates to a non-woven fabric production equipment, in particular to a one-time molded composite production equipment of various melt-blown filter materials. Background technique [0002] Usually, the 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 that matches the nozzle, and a single melt-blown raw material is sprayed on the receiving machine through the process 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, and the equipment investment is large. The integrit...

[0002] Usually, the 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 that matches the nozzle, and a single melt-blown raw material is sprayed on the receiving machine through the process 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, and the investment in equipment is large. The integrity and organic combination of the spray filter cloth will affect the use effect

At present, the feeding of the screw extruder is manual feeding, the feeding amount is not easy to control, time-consuming and laborious, and it is impossible to realize the automatic production of the screw extruder
