Plastic Auxiliary Machinery-Feeding/Mixing Equipment-Metering System
Brief description:The plastic blending side-feeding industrial system is designed for adding masterbatches and other additives. Some systems have metering functions, which require more complex control systems. In contrast, a simple injection addition function is relatively straightforward, involving a small screw (a welded part will suffice) driven by a geared motor, with the outer wall made of seamless steel pipe, and speed controlled by a variable frequency drive.
Plastic Mixing Side Feeding Industrial SystemPrecautions：
The inner 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 stagnant 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支架造成的结合缝部分似乎没有完全翻译。让我直接给出完整的英文翻译：
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 and make the product dense.
3. Correct Cross-sectional Shape: Due to factors such as the properties of plastics, pressure, density, and shrinkage, there is a difference between the cross-sectional shape formed by the die in the head and the actual cross-sectional shape of the product. This factor must be considered during design to ensure that the die in the head has a reasonable cross-sectional shape.
4. The design should have a compact rhythm, be easy to assemble and disassemble. Under the condition of meeting mechanical performance, the head should be designed to advance rhythmically, with tight connections, uniform heat transfer, easy assembly and disassembly, and without material leakage.
5. Material selection should be reasonable. The die head should be made of steel that is corrosion-resistant, wear-resistant, has good tensile strength, and high hardness. In some cases, it also needs to be chrome-plated depending on the situation.
Maintenance Key Points:
1. For batching and metered feeding, to ensure uniform and stable feeding and prevent material from flowing freely, it should be installed horizontally. For continuous feeding of general materials, it can be installed at a 10° downward angle. For sticky materials and those with higher moisture content, it can be installed at a 15° downward angle.
2, After installation, a clearance of 20mm should be left for movement, it should be level horizontally, and the hanging device should use a flexible connection.
3. Before the no-load test, all bolts should be tightened once, especially the foundation bolts of the vibrating electromagnet. After 3-5 hours of continuous operation, they should be retightened. During the test run, both vibration motors must rotate in the same direction.
4. During the feeding process, the amplitude, current, and noise stability should be frequently checked. If any abnormalities are detected, the machine should be stopped immediately for handling.
5. The electromagnetic bearing should be lubricated once every 2 months, and it should be lubricated once a month during the high-temperature season.
Check the control panel of the equipment to see if there are any issues, such as the parameters of the feeder, whether the suction and discharge times are correct. If there is a problem here, it might not be able to suction materials properly, and changes should be made promptly to resolve the issue.
2. Check the pneumatic pump to see if its compressed air source pressure meets the relevant regulations. In most cases, the air source pressure for a pneumatic pump is 6-7 MPa. If the pressure does not meet the requirements, it should be checked whether the air source needs to have its ventilation pipe replaced.
3. The inability to properly draw in material may also be due to the disassembly and reassembly of the machine, resulting in air leakage at the clamp between the top cover and the barrel, thus preventing normal material drawing operations.
4. Open the top cover, remove the filter plate, and observe whether there is too much dust or any clumping on the filter element. These issues can lead to improper suction. To resolve this, simply clean it with compressed air.
