Brief Description:Screw-type plastic pelletizing machines are mainly used for coloring polymer materials, primarily divided into black masterbatch, white masterbatch, color masterbatch, and liquid color masterbatch.
The machine is primarily used for coloring polymer materials, mainly divided into black masterbatch, white masterbatch, color masterbatch, and liquid color masterbatch.
Features:
This production line integrates mixing, conveying, feeding, and extrusion, achieving automated continuous operation with high production efficiency.
2. Compact structure, occupying minimal floor and space, suitable for flat installation.
3. The production process is divided into segments with closed-loop temperature control. 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, with strong material intake capability. It is particularly suitable for extruding and pelletizing chunky materials directly from an internal mixer.
5. The barrel and screw are 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 and wide-range speed adjustment for feeding, extrusion, cutting, and other multi-machine operations according to process requirements. It also features comprehensive process interlocks, audio-visual fault alarms, and other control functions, ensuring a complete and reliable system.
1. Always pay attention to the changes in the body temperature. When the strands do not stick to your hand upon touching with a clean hand, you should immediately increase the temperature until the strands stick to your hand, which is considered normal.
2. If the bearing part of the gearbox feels hot or is accompanied by noise, it should be inspected and lubricated promptly.
3. If the bearing areas at both ends of the main unit's bearing housing become hot to the touch or produce unusual noises, stop the machine for inspection and apply grease. During normal operation, grease should be added to the bearing housing every 5-6 days.
4. Pay attention to understanding the operating patterns of the machine; for example: the temperature and rotational speed. Adjustments should be made promptly based on the situation.
5. When the machine body operates unstably, attention should be paid to checking whether the coupling fit clearance is too tight, and it should be adjusted to be looser in time.
Maintenance:
1. The plastic pelletizing machine should first be placed in a well-ventilated area to ensure that the heat generated by the motor can dissipate, thereby extending its lifespan.
2. Observe the gear oil of the reducer daily, and the oil level should be maintained at the midpoint of the oil window. Lubricating oil should be regularly added to the bearings to ensure lubrication between them; check the cooling water of the reducer daily, and during operation, the cooling water should be in a slow flowing state (the water flow must not be too rapid or the water pressure too high, to avoid detaching the copper weld of the cooling pipe 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 to enhance the stability between the blades and the blade holder.
4. To ensure the sharpness of the cut, the blade should be checked regularly to maintain its sharpness, reducing unnecessary damage to other components caused by a dull or chipped 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 well grounded.
