Problems solved by technology

[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
