    ​

    Material transport

    Screw Loader

    Lumps or thick flakes after crushed, conveyed into the single screw extruder by screw loader, then, compress, plasticize in the extruder and removed volatiles and moisture by vacuum system, after filtering through the filtration system, to pelletize into granules. Depending on the different screw diameters of single screw, the typical capacity can cover from 100kg/h to 1000kg/h,Loading motor power: 2.2 kw. Conveying pipe made with stainless steel material, pipe inner thickness is 2mm, pipe diameter is 102mm.

    Main feeder (Volumetric)

    Metal detector can be combined with belt conveyor, and can interlock with contrl system, to warn and stop the system, in case that metal is found in feeding.

    Gear Box

    Gear Box

    The gearbox will reduce the motor speed to the screw shafts speed and distributes it to the two output shafts.Low-noise, high torque output.

    Double Screw Extruder

    ATE Parallel Twin Screw Extruder

    The twin screw extruder will gently plasticizes the materials.our unique bi-metal twin screw extruder has greater homogenization efficiency and long life time.

    Silo Light Tube

    Can watch the working state of the machine.

    Vacuum Degassing System

    This vacuum  system will remove  the volatile in the agglomerates and improve the quality of granules. It equipped one-channel value to avoid water back-flowing.

    Cast Copper and Aluminum Heater  

    Cast copper and aluminum heater , easy to assemble and disaassemble. Faster heating and low energy waste.

    Soft Water Cooling System

    Material of input and output pipes is stainless steel. Manual valves to adjust flowing rate of cooling water; solenoid valves are to control opening and closing of cooling water flowing in.

    Filtration system

      None-Stop Piston Type Filter
    • A regular single-plate/piston double-station screen changer or non-stop double plate/piston four-station can be installed on head of extruder to present significant filtration performance.
    •  Long screen lifetime, lower screen change frequency: Long filter lifetime owing to large filter areas.
    •  Easy to use and none-stop type: easy and quick screen change and do not need to stop the running machine.
    • Very low operation cost.
    Plate Type Filter 

    The Plate type filter is made in a continuous type with two filter plates. There is at least one filter working when the screen is changing.Ring-shaped heater for consistent and stable heating.

    Self Clean Filter

    This model combines our self-developed self-cleaning filter.The new SCF self-cleaning filtration system makes non-stopping recycling extrusion, especially suitable to highly contaminated materials re-pelletizing. SCF filtration system can handle and remove up to 5% contaminates in the melt flowing, can separate the contaminates as: paper, wood, aluminum, unmelted plastic and rubbers etc.

    Pelletizing system

    Die Head

    This is the most appropriate process for the need for better melt filtration and higher production. In the first stage,two or more single screw extruders can be designed for the two-stage pelletizing production line, and then they can enter the second-stage extruder at the same time.

     

    Water Ring Pelletizing System
    • Self-adjusting pelletizing head for the best granulate quality and long uptime thanks to consistently correct blades pressure.
    •  RPM of rotatory blades is automatic based on melt extruding pressure.
    • Easy and fast pelletizer blades changeover, without adjustment work saves time
    Strand Pelletizing

    The strip-shaped Melted plastic strands passes through the cooling water tank and is quickly cooled and solidified. During the cooling process, the strip is pulled out by the traction device, maintaining a certain speed and stability. Then, the strip enters the pelletizer and is cut into pellets of a certain length by the rotating cutter.

     

    Under-Water Pelletizing System

    Highly automatic pelletizing system. It is suitable for materials with high MFI and high production capacity requirements. This system includes pelletizer, valve, conveying pipeline, dewatering vibrating screen, silo.

     

    Vibration Dry

    Vibration Dry
    • Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption. 
    •  Assemble sieves: The sieves are installed and fixed by screws instead of welding, so you can change the sieves easily in the future.
    Plastic Particles

    Final output: plastic particles,the plastic pellets can be re-used for producing high quality plastic products once again.

     

    Packing System

    Packing System
    • Final qualified granules store here，the drying shaker together with the horizontal centrifuge can get a good drying result, and less energy consumption.
    • Capacity online monitoring & Quantitative weighting system.

    Aceretech Palletizing Conveyor System

    Palletizing Conveyor System


    After the sealed package is poured onto the receiving belt conveyor, the climbing conveyor lifts the package to the required height for robot palletizing and grabbing. It then enters the weight recheck scale to recheck the accuracy. Products with unqualified accuracy are removed by the removal and shaping machine, while qualified products are shaken and shaped by the vibration shaping and pressing conveyor. After shaping is completed, the package is transported to the position of the coding
    conveyor for coding. After coding is completed, the package is transported to the grabbing conveyor and waiting for the robot to grasp the palletizing.

    Palletizing Conveyor System Including

    Aceretech Stacking Robot System

    Stacking Robot System


    * Adopting ergonomic design, comfortable and lightweight operation ;
    * Display in both Chinese and English, with a user-friendly interface ;
    * Dual safety switch, fully ensuring the safety of personnel operation ;
    * Equipped with USB interface, supporting import/ export of teaching programs ;


    Tray Storage System

    The pallet storage warehouse transports empty pallets to the palletizing conveyor through the empty pallet conveyor and waits for the robot to palletize them. When there are material packages on the grabbing conveyor, the robot starts palletizing and stacks them onto the pallet of the palletizing conveyor; Complete the palletizing operation according to the prescribed grouping mode, and the full stack of material packages will enter the online winding machine for automatic film wrapping, and then be covered with film on the top by the top covering machine; The wrapped products enter the full stack fork picking conveyor and wait for the forklift to pick them up.
