Plastic Auxiliary Machinery-Feeding/Mixing Equipment-Metering System
Brief Description: The side feeder is designed for adding additives such as color masterbatch. Some models also have metering functions. The control system for metering functions is relatively complex, while the simple additive injection function is more straightforward, driven by a geared motor that rotates a small screw (which can be a welded component), with the outer wall made of seamless steel pipe, and speed is adjusted via a frequency converter.
Side FeederIntroduction:
The machine is designed for adding additives such as color masterbatch. Some models also have metering functions. The control system for metering functions is relatively complex, while the simple additive injection function is more straightforward, driven by a geared motor that rotates a small screw (which can be a welded component), with the outer wall made of seamless steel pipe, and speed is adjusted via a frequency converter.
Features: Equipped with corresponding screws and auxiliary machines, it can directly extrude various thermoplastics, especially rigid PVC powder, into pipes, plates, sheets, films, and profiles, and can also complete the modification of various plastics and the granulation process of powders. It uses a DC motor, thyristor stepless speed control, equipped with overload protection and fault alarm, screw core oil circulation constant temperature, barrel oil cooling, and is equipped with a vacuum exhaust pipe device and a quantitative feeding device.
Control System:
1. The oil lubrication system is interlocked with the host, meaning the host can only be started after the oil pump is activated.
2. The feeding system is interlocked with the host, meaning the feeder can only be started after the host is activated.
3. The pressure system is interlocked with the host, meaning both the host and feeder will stop working in case of overpressure.
4. The current system is interlocked with the host, meaning both the host and feeder will stop working in case of overcurrent.
Side Feeder Precautions:
1. The inner cavity of the die head should be streamlined. To ensure that the material is evenly extruded along the die head flow channel and to avoid overheating decomposition due to stagnation, there should be no sharp contractions in the die head, and dead corners or stagnant areas must be avoided. The flow channel should be as smooth as possible, with a recommended surface roughness Ra value of 0.4μm.
2. Sufficient compression ratio. Depending on the plastic product and type, design a die head that can generate sufficient compression ratio to eliminate the joint seam caused by the分流支架, ensuring the product is dense.
3. Correct cross-sectional shape. Due to factors such as plastic properties, pressure, density, and shrinkage rate, the cross-sectional shape of the die head's mold differs from the actual cross-section of the product. This factor should be considered in the design to ensure the die head has a reasonable cross-sectional shape.
4. Compact structure, easy to disassemble and assemble. While meeting mechanical performance requirements, the die head should be designed with a compact structure, tight connections, uniform heat transfer, easy disassembly and assembly, and no material leakage.
5. Reasonable material selection. The die head should be made of corrosion-resistant, wear-resistant, high tensile strength, and hard steel. Some may also require chrome plating depending on the situation.
