The invention discloses an environment-friendly type bast
fiber film preparation device, which comprises two feeding machines, a feed mixer, a crude opening
machine, a fine opening
machine, a vibrating air pressure bast feeding box, a
carding machine, a mechanical cross lapper, an air-lay machine, an impregnator, a
drying can type pre-
drying pit, an air-pressure double-roller
planishing mill, a surface spraying
coating machine, a
drying can type dying setting machine, a drafting side
cut lap former and the other operation unit machines. Each unit-
air conditioning adopts variable-frequency control and a
synchronizer to control electric appliances, and each unit-
air conditioning can be singly operated in high speed, and can be interlocked to operate with complete equipment. The invention has the advantages that fibrilia is delivered by an
airflow pipeline on the crude opening machine, and between the crude opening machine and the
carding machine, and the supply of
raw material is continuous, net is combined in two times through a machine to pave net and
airflow to form net, bast
fiber film net has little density, even strength and stable quality, even
coating layers are coated and sprayed on double faces of bast
fiber film, and bast fiber film with different functions and usages can be made, continuous and stable full-automatic production of bast fiber film can be achieved.
