Brief Description:Industrial extrusion pelletizing systems are mainly used for coloring polymer materials, primarily divided into black masterbatch, white masterbatch, color masterbatch, and liquid color masterbatch.
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 basis for the external form, or in other words, the external form is the outward manifestation of the internal structure. This relationship is quite 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 itself. Given that the main work of industrial design is reflected in the appearance of the equipment, the structural and styling design of the exterior components are very closely related.
In the degradable 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 about 1750 rpm, which is too fast for an extruder screw. If it rotates at such a high speed, it will generate too much frictional heat and fail to prepare a uniform, well-mixed melt due to the too short residence time of the plastic. The typical reduction ratio should be between 10:1 and 20:1, with the first stage using either gears or pulleys, but the second stage uses gears and positions the screw at the center of the large gear. For some machines that operate at a slower speed, 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 very long twin-screws used for mixing can operate at speeds of 600 rpm or faster, thus requiring a very low reduction ratio and more intense cooling.
The entire process consists of two steps: mixing and drawing.
2. The adhesive enters the material pot from the conical hopper. After the hopper is closed, the powder rotates within the container under the stirring of the mixing paddles, while the material moves along the direction of the conical wall, gradually forming liquid bridges. Under the squeezing, friction, and kneading actions of the paddles and the cylinder walls on the material, it gradually transforms into a loose substance. Then, the discharge door is opened, and the mixed granules are pushed out of the discharge hopper by the centrifugal force of the paddles.
3. The soft material with a granular structure is not formed by forced extrusion, but rather it is cut by the granulation force, where the soft material in a semi-fluid state is cut into fine and uniform particles, achieving the mutual transformation of the material.
