Pulp Moulding Machine is known as egg tray line for using massively
in produce egg tray.
Pulp Moulding Machine, which uses waste paper, cardboard, leftover
material of paper mill, by hydraulic pulper, mix making a certain
dense pulp, and pulp is absorbed by vacuum of special metal
moulding to become wet products, through drying , and shaping to
become finished products.
Pulp Moulding Line processing makes use of recycled water and does
not lead to water or air pollution. Finished packaging products can
be recycled after being used in storage, transport, and sales.
After shredding, they are easy to be decomposed as paper, even if
discarded into the natural environment.
Automatic pulp molding production lines can be mass production of
various food container, egg tray, lunch boxes and so on.
The major equipment of the machine are three parts include: Pulp
Making System, Molding System, Drying system and packing system.
Introduction of equipment
Step 1:Put the prepared raw materials,such as waste paper carton,newspaper
etc. into hydrapulper,making paper pulp by the shear force and
friction force of water,transfer the prepared paper pulp into pulp
pool.
Step 2:Transfer the paper pulp into mixing pool 1,filtering the impurities
out of paper pulp at the same time,adjusting the concentration of
the pulp.
Step 3:Transfer the paper pulp which in mixing pool 1 into mixing 2 for
second mixing.Now you can add such as color agent,waterproof and so
on materials by your needs,stirred sufficiently.
Stept 4:Pumping the prepared paper pulp from mixing pool 2 by pulp pump
into molding machine,then the mold on the top sink into paper pulp
completely,under the pumping action of the mold which has vacuum
action in the back,pulp is adsorbed on the surface of the mold,at
the same time,water in the pulp is pumped out,then the wet paper
tray was formed on the surface of the mold.
Step 5:When the molding machine working,the water in the pulp will pumped
out by the vacuum pump,then discharging the waste water into waste
water pool.
Step 6:Waste water in the waste water can be recycling used.Transfer the
waster into hydrapulper and mixing pool by waster paper pump to
recycled used.
Step 7:Dying,the wet paper tray on the mold is about 2.5mm thickness and
contain 75% moisture,then send the wet paper tray into
dryer(120-180℃).
Stept 8:Packaging the final paper egg tray into warehouse.
