Our ZM series automatic egg tray making machine is consistedof
paper pulping equipment, pulp molding equipment, drying equipment
withheating source, heat-press equipment for egg carton’s shaping,
electronicoperating system, and some other auxiliary equipment.
1.Paper Pulping Equipment
The paper pulping equipment is used for makingrecycled waste paper to
There is hydraulic pulper equips in our eggtray production line. The
hydraulic pulper will make the recycled waste paper tobe thick
pulp, and the pulp pump will pump the thick pulp into the
pulppreparing tank. Meanwhile, impurities in the waste paper will
be vented fromdregs exit of the pulper.
In the pulp preparing tank, thereis a pulp stirrer to avoid
deposition of the pulp. As per detailed requirementof diverse kinds
of product, it needs to put relevant additive into the pulp inthe
pulp preparing tank to achieve waterproof ability or improve
performance ofthe paper pulp product.
After additive’s putting, it needs to pour cleanwater into the pulp
preparing tank to dilute the thick pulp to be finished pulp.Then
the pulp pump will pump the finished pulp into the pulp chest of
the pulpmolding machine.
There is a white water tank to containclean water as well recycled water
from the pulp molding machine and the vacuumpump. The white water
pumps will pump water into the hydraulic pulper and pulppreparing
As for raw material of the pulp, werecommend our customers to use
admixture of recycled waste news paper orrecycled waste book
together with recycled waste corrugated board.
Characteristic of our Hydraulic Pulper
2. Pulp Molding Machine
Pulp molding machineis used for molding paper pulp product.
After the lower mold plate diving into the pulp chest of thepulp molding
machine, the molding molds will begin to inhale pulp by vacuumpump.
Then the lower mold plate will leave the pulp chest and get up to
meet theupper mold plate. In succession, carrying the transferring
molds, the upper moldplate will move to meet the lower mold plate
and transfer the pulp product frommolding molds onto transferring
Then the upper moldplate will take the pulp product to entrance of the
drying tunnel and smoothlyrelease the pulp product onto the
conveying belt of the drying tunnel. Afterpulp product’s transfer,
the lower mold plate will come back to the pulp chestfor new cycle.
All actions of the pulp molding machine are controlled byPLC.
Our egg tray producing machine needs 2 kinds ofauxiliary equipment,
which includes vacuum equipment and compressed airequipment.
Vacuum equipment includes vacuum pump, vacuumtank, dehydration pump,
air-water separator, etc. Vacuum pump is used to producevacuum air.
Vacuum tank is used for storage of the vacuum air. And
dehydrationpump is used to pump out the water in the vacuum tank.
Compressed airequipment mainly includes air compressor and air
storage tank. The compressedair is driving force of the molding
Characteristic of our Pulp Molding Machine
Controlled by PLC, our pulp molding production line runs
automatically tosave labor cost for our customer.
Thanks to reasonable machine structure, diverse kinds of pulp
product can beproduced. By changing molds, our pulp molding
equipment can make many kinds ofpulp trays, such as egg trays, egg
cartons, bottle trays, electric spare parttrays, fruit trays, etc.
Advanced design and perfect function to guarantee easy operate and
Molds are very important partfor the paper pulp moulding production
process. The shape, structure andprecision of molds directly affect
the final size, appearance and quality of thefinished pulp product
as well as production efficiency.
Characteristic of our Molds
Designed by 3D
Produced by CNC
Perfect structure; high precision; good interchanging performance
High quality stainless steel filtering net for molding molds
Customization requirement is accepted.
4. Drying equipment with heating source
After molding, the wet pulp product will contain around 70%of water.
So, our egg tray molding equipment equips a drying tunnel for
dryingthe wet pulp product.
The wet pulp product that is producedby the egg tray mouldin
