Brief description:Material extrusion and pelletizing equipment is mainly used for coloring polymer materials, primarily divided into black masterbatch, white masterbatch, color masterbatch, and liquid color masterbatch.
Material extrusion granulation equipmentEquipmentIntroduction:
The internal structure of the machine largely depends on the design principles, and it can be said that technical elements influence its internal structure. The internal structure, in turn, serves as the foundation for the external form, or in other words, the external form is the outward manifestation of the internal structure. This relationship is particularly evident in the exterior design of box-type components.
In addition to the internal structure, there is an inclusive relationship between the internal structure and the external form, with the external form sometimes being a structural design in itself. Given that the primary work of industrial design is reflected in the appearance of the equipment, the structural and shape design of the exterior components are very closely related.
In the degradation material modification pelletizing machine, the change in screw speed is achieved by adjusting the motor speed. The drive motor usually rotates at full speed of approximately 1750 rpm, which is too fast for an extruder screw. If it were to rotate at such a high speed, it would generate too much frictional heat and result in insufficient plastic residence time, making it impossible to prepare a uniform, well-mixed melt. The typical reduction ratio should be between 10:1 and 20:1. The first stage can use either gears or pulleys, but the second stage uses gears with the screw positioned at the center of the large gear. For some machines operating at slower speeds, there may be three stages of reduction, with the maximum speed possibly as low as 30 rpm or even lower (with a ratio up to 60:1). On the other hand, some long twin screws used for mixing can operate at speeds of 600 rpm or faster, thus requiring a very low reduction ratio and more intensive cooling.
Precautions for Material Extrusion Pelletizing Equipment
掺入铁质杂质
Introduce iron impurities
First, during the use of this equipment, we must inspect the material being fed in. The material should not contain any iron impurities, as these can cause damage to the machinery or excessive wear.
2, Idle Adhesive Shaft
Secondly, during use, we must also prevent the machinery from running idle without any load, as idling can cause the shaft to heat up, leading to clumping and adhesion of various materials. Throughout the operation, we need to inspect and select the materials being fed in, constantly monitoring whether the machinery is in an idle state, and promptly removing any impurities mixed within the materials. This can help extend the service life of the machinery.
After the temperature stabilizes, the machine can be started. Before starting, the bolts of the die head and the extruder flange should be tightened again to eliminate the difference in thermal expansion between the bolts and the die head. The sequence for tightening the die head bolts should be diagonally, with even force applied. When tightening the die head flange nuts, it is required that the tightness around is consistent; otherwise, material leakage may occur. During operation, select the preparation start button, then press the start button, and slowly turn the screw speed adjustment knob to gradually start the screw rotation. Then, gradually increase the speed while feeding a small amount of material. During feeding, closely monitor the changes in the main motor's ammeter and various indicator gauges, ensuring that the screw torque does not exceed the red mark. No one should stand in front of the die before the plastic profile is extruded, to avoid injury due to bolt breakage or moisture-induced foaming. After the plastic is extruded from the die, the extrudate needs to be slowly cooled, and the devices and shaping molds should be moved, followed by adjustments according to the readings on the control instruments.
