Paper pulp molding/moulding product is a kind of packaging which is
made from waste paper and pulp cardboard by appropriative equipment
and unique technics. Firstly, paper pulp molding/moulding products
are only applied to the transport packaging of farm produce such as
egg ,fruit and so on. But gradually, the range of application and
research is enlarged to the safeguard packaging of industrial
product, such like the electronic product, household appliances,
apparatus, glassware, crockery, minitype machine etc.
A complete pulp molded production line consists of Stock
Preparation System Section, Molding Machine Section, Continuous
Drying Oven and Conveyor System, Process Instrumentation,
Instrument and Control Panels, Jobsite Installation Materials,
Auxiliary Equipment, etc.
Equipment Process
Pulping system
(1) Put the raw material into the pulper and add an appropriate
amount of water for a long time to stir the waste paper into pulp
and store it in the storage tank.
(2) Put the pulp in the slurry tank into the pulping tank, adjust
the pulp concentration in the pulping tank, and further stir
through the homogenizer through the white water of the return pool
and the thick slurry of the storage tank. After adjusting to the
applicable pulp, put it into the feeding pool to be used in the
molding system.
Equipment used: pulping machine, homogenizer, slurry pump,
vibrating screen, pulp disintegrator
2. Forming system
(1) The pulp in the supply tank is supplied into the molding
machine, and is adsorbed by the vacuum system, and the pulp is left
on the mold by the mold on the equipment to be formed, and the
white water is sucked and transported back into the pool through
the vacuum pump.
(2) After the mold is adsorbed, the transfer mold is blown out by
the positive pressure of the air compressor, and the molded product
is blown from the molding die to the rotary mold, and is sent out
by the transfer mold.
Equipment used: molding machine, mold, vacuum pump, vacuum tank,
pump, air compressor, mold cleaning machine
3. Drying system
(1) Natural drying method: The product is dried directly by weather
and natural wind.
(2) Traditional drying: brick tunnel kiln, heat source can choose
natural gas, diesel, coal, dry wood,A heat source such as liquefied
petroleum gas.
(3) New multi-layer drying line: 6-layer metal drying line can save
more than 30% energy compared to transmission drying. The main heat
source is clean energy such as natural gas, diesel oil, liquefied
petroleum gas and methanol.
4. Finished product auxiliary packaging
(1) Automatic stacking machine
(2) Baler
(3) Transfer conveyor
