3.1DJ85 Single screw extruder

1

Belt conveyor


As a standardized design, plastic wastes such as film, silk, rope, bags, non-woven fabrics are conveyed into the compaction bin of the cuishi system through the belt feeding device. The conveying speed of the belt feeding device is linked with the fullness of the compaction bin, and the conveying speed of the waste material is automatically adjusted according to the fullness of the compaction bin.

Motor power: 1.5kw

Width of the belt conveyer: 400mm

Length of the transportation: 5000mm

With metal detector: Chinese brand

2

Compactor


 

The movable knife in the compaction bin rotates to cut and crush the waste material entering the bin. The high-speed rotating moving knife, while crushing the material, generates frictional heat to pre-dry the waste. At the same time, with the help of a specially designed temperature control and speed control system, the heat-absorbing waste is pre-processed below the melting point temperature. shrink. The pre-shrunk waste is compacted by the guide groove inside the silo wall, and forced into the extruder feeding barrel by the centrifugal force of the rotating knife. Through this integrated process of crushing, drying and compacting, the stability and high efficiency of feeding waste with low bulk density are ensured.

Water ring cutting system


 

 


The speed of the pelletizing blade is automatically adjusted until the final uniform pellets appear.

The pneumatic device is used to feed the knife to ensure good contact between the

blade and the die, and the pressure of the knife is automatically adjusted to

ensure the uniform cutting force of the knife.

Start the system with one key to make the operation of the whole system more

convenient;

Horizontal die face cutter

According to the set logical sequence and material handling process requirements, the linked cuishi system realizes one-key startup, thus avoiding mistakes in the manual startup process.

Smart shutdown: one-key shutdown

With the help of a specially customized unit, the cuishi system can realize one-key shutdown of the entire system module to avoid equipment damage caused by incorrect operation during manual shutdown.

Emergency stop device

cuishi is equipped with an emergency stop function, which is used as an emergency for uncertain risks during the operation of the machine, shutting down the entire system promptly and quickly to avoid secondary accidents and injuries.

Protection System

Life safety protection device

The cuishi system fully takes into account the safety issues of the equipment during operation. Each operating station and rotating part position are equipped with electronic safety switches to ensure the safety of the equipment during operation and avoid potential hazards during the operation of the equipment to cause harm to the customer's operators.

Plastic performance retention

With the help of a precise temperature control system and a targeted optimization design of the plasticizing process section, the cuishi system can ensure the reliability and stability of the final pelleting quality.

Overheating protection device for compaction chamber

With the help of modular control principle and full cognition of the performance of different recycled materials, the cuishi system can ensure that the processed waste material achieves the optimal preheating and compaction state in the compaction chamber, and can avoid the plastic return material from being compacted. Overheating or degradation in the warehouse.
