Brief Description:Twin-screw black masterbatch pelletizing equipment is mainly used for coloring polymer materials, and it is primarily divided into black masterbatch, white masterbatch, color masterbatch, and liquid masterbatch.
Twin-screw black masterbatch pelletizing equipmentFeatures:
This production line integrates mixing, conveying, feeding, and extrusion, achieving automated continuous operation with high production efficiency.
2. Compact structure, small footprint and space requirement, suitable for flat installation.
3. The production process is carried out with segmented closed-loop temperature control, where the internal mixer, feeder, and extruder each have their own heating and cooling systems, controlling their respective temperatures according to the process requirements.
4. The feeding mechanism adopts a dual-paddle screw design, featuring strong material intake capability. It is particularly suitable for extrusion and pelletizing of lump materials directly from an internal mixer.
5. The barrel and screw are both made of high-quality 38CrMoAIA alloy steel, which has undergone nitriding treatment, resulting in high hardness, wear resistance, and corrosion resistance.
6. The die head adopts a manual screen changing or quick non-stop screen changing mechanism to improve production efficiency.
7. The electrical control system adopts advanced PLC control technology, combined with multiple inverters, enabling high-precision, wide-range speed adjustment for feeding, extrusion, cutting, and other multi-station processes according to the process requirements. It also features full-process interlocking, audio-visual fault alarms, and other functional controls, ensuring a comprehensive and reliable operation.
Maintenance:
1. First, the plastic pelletizing machine should be placed in a well-ventilated location to ensure that the heat generated by the motor can dissipate, thereby extending its lifespan.
2. Observe the gear oil in the gearbox daily, and the oil level should be maintained at the midline of the oil window. Lubricating oil should be regularly added to the bearings to ensure lubrication between them; check the cooling water of the gearbox daily, and during operation, the cooling water should be in a slow flowing state (the flow rate and water pressure must not be too high, to avoid detaching the copper welds of the cooling pipes inside the box).
3. Regularly check the screws; after using a new plastic pelletizing machine for 1 hour, use tools to tighten the screws of the moving and fixed blades, enhancing the stability between the blades and the blade holder.
4. To ensure the sharpness of the cut, the knife should be regularly checked and maintained to keep it sharp, reducing unnecessary damage to other components caused by a dull blade.
5. When replacing the blades, the gap between the moving blade and the fixed blade: for 20HP and above, the thinner the recycled material, the larger the gap can be appropriately adjusted.
6. Before the second start, the remaining debris in the machine room should be cleared to reduce the starting resistance;
7. The inertia cover and pulley cover should be opened regularly to clean the dust outlet below the flange, as powder from the plastic pelletizing machine chamber can enter the shaft bearings.
8. The plastic pelletizing machine should be kept in good grounding.
Twin-screw black masterbatch pelletizing equipmentPrecautions:
1. Before starting, heat for about 40 to 50 minutes first, raising the temperature to a state where it is easier to pull the motor V-belt by hand. Pull in the normal working direction 8 to 10 times, and continue heating for about 10 more minutes; at this time, continue heating because normal production requires continuous heat supplementation; adjust different temperatures according to the varying properties of the plastic.
2. Before the equipment is put into normal operation, the stability of the mechanical temperature should be maintained, and the mechanical temperature should not be kept at either a high or low level.
3. If the feeding is uniform, the machine's feeding speed should match the conveying speed; otherwise, it will directly affect the quality and output of the plastic pellets.
4. Before stopping, all the plastic inside the granulator screw must be emptied and cleaned.
5. When shutting down the main unit, the power supply should be disconnected, and before the next use, the nozzle and line plug must be disassembled and preheated separately.
