Plastic Auxiliary Machinery-Feeding/Mixing Equipment-Metering System
Brief description:The side feeder of the mixing auxiliary system is designed for adding color masterbatches and other additives. Some have metering functions, which require a more complex control system. In contrast, a simple injection function is relatively straightforward, achieved by using a geared motor to drive a small screw (a welded part will suffice), with the outer wall made of seamless steel pipe, and speed controlled by a variable frequency drive.
Side feeder for the blending auxiliary systemIntroduction:
The machine is designed for adding color masterbatches and other additives. Some models feature metering functions, which require a more complex control system. In contrast, the simple addition and injection function is relatively straightforward, achieved by using a geared motor to drive a small screw (a welded part will suffice), with the outer wall made of seamless steel pipe, and speed controlled via a variable frequency drive.
Features: Equipped with the corresponding screws and auxiliary equipment, it can directly extrude various thermoplastics, especially rigid PVC powder, into pipes, sheets, films, and profiles, etc. It can also complete the modification of various plastics and the granulation process of powders. It adopts a DC motor, thyristor infinitely variable speed control, and is equipped with overload protection and fault alarm. The screw core has an oil circulation constant temperature system, the barrel has an oil cooling system, and it is installed with a vacuum exhaust pipe device and a quantitative feeding device.
Side Feeder for Blending Auxiliary SystemPrecautions：
The internal cavity of the die head should be streamlined to ensure that the material can be extruded uniformly along the flow channel, avoiding overheating and decomposition due to stagnation. There must not be any abrupt narrowing in the die head, and there should be no dead spots or stagnation areas. The flow channel should be as smooth as possible, with a recommended surface roughness Ra value of 0.4μm.
2. Sufficient compression ratio: The die head should be designed to generate a sufficient compression ratio according to the different types of plastic products and plastic varieties, in order to eliminate the weld lines caused by the diverter supports and make the product dense.
3, Correct Cross-Sectional Shape Due to factors such as the properties of plastics, pressure, density, and shrinkage rate, there is a difference between the cross-sectional shape formed by the die of the machine head and the actual cross-sectional shape of the product. This factor must be considered during design to ensure that the die of the machine head has a reasonable cross-sectional shape.
4. With a compact rhythm, easy to assemble and disassemble, the die should be designed to have a steady progression, tight connections, uniform heat transfer, convenient assembly and disassembly, and no material leakage under the condition of meeting mechanical performance requirements.
5. Material selection should be reasonable. The die head should use steel that is corrosion-resistant, wear-resistant, has good tensile strength, and high hardness. In some cases, it also needs to be chrome-plated according to the situation.
