Meltblown Nonwoven Fabric Making Machine
This equipment is used for the production of melt blown nonwoven fabric.
Different colors and functions of melt blown nonwovens are produced with polypropylene fiber as the main raw material, supplemented by Color Masterbatch, antioxidant, electrostatic electret, flame retardant and other additives.
The products are widely used in industrial felt, industrial oil absorbent cloth, industrial sound insulation cotton, industrial high efficiency filter material, etc. at the same time, the production line can also produce disposable ordinary melt blown cloth for mask and melt blown cloth for mask which can achieve N90 or above high efficiency by adding electret masterbatch and electrostatic electret treatment.

Features | ||||
Dosing & metering system | Vacuum suction or blower feeding system. Gravimetric metering system with precise accuracy. Automatic alarm for high and low position limit. | |||
Spinning beam | Single coat-hanger melt distribution, manufactured by 4-coordinates CNC, grinding by manual. | |||
Quenching chamber | Several layers multistep honey plates with different size holes. Quenching air distribution is uniform and easier for dismounting and cleaning. | |||
Stretching channel | Inside wall is made of polished stainless steel, top and bottom stretching channels can adjust slot width at the same time. | |||
Diffusing channel | Channel is made of stainless steel. Special forming process and welding technology guarantee the whole channel is flat and no shape changing. | |||
Conveyor | Rollers are inspected by dynamic balance to guarantee running in stable situation. Surface of prepressing roller is coated by ceramic, to prevent entanglement. MB system has pneumatic belt protection unit. | |||
Meltblown system | Imported screw blower has been applied to create stretching air. Pressure is constant, Spinning pressure is lower, higher efficiency and less power consumption. | |||
Electrical control system | The whole machine is controlled by PLC, AC inversion motor for the whole synchronization system, The process parameters and fault can be displayed and alarmed. The whole system is in stable and reliable situation. |
