Main Equipment Introduction

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 be pulp.

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 tank.

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

  • Reasonable structure

  • Stable workability

  • Low electricity-consumption

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 molds.

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 machine.

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 maintain.

3. Moulds

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.
