Plastic Auxiliary Machinery-Feeding/Mixing Equipment-Metering System
Brief Description:The automatic side-feeding system for mixing is designed to add color masterbatches and other additives. Some systems also have metering functions. The control systems that require metering functions are more complex. In contrast, a simple injection addition 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.
Automatic side feeding system for mixingIntroduction:
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 driving a small screw (which can be a welded part) with a geared motor. The outer wall can be made of seamless steel pipe, and the speed can be adjusted using a variable frequency drive.
Features: Equipped with the corresponding screws and auxiliary machines, it can directly extrude various thermoplastics, especially rigid PVC powder, into pipes, sheets, films, and profiles, as well as complete the modification of various plastics and the granulation process of powders. It adopts a DC motor, thyristor infinite speed regulation, and is equipped with overload protection and fault alarm, screw core oil circulation constant temperature, barrel oil cooling, and is fitted with a vacuum exhaust pipe device and a quantitative feeding device.
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, and it should be level horizontally. 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 continuous operation for 3-5 hours, they should be retightened. During the test run, both vibrating motors must rotate in the same direction.
4. During the feeding process, the amplitude, current, and noise stability should be checked frequently; 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 during the high-temperature season, it should be lubricated once a month.
Automatic side feeding system for mixingCommon faults:
Check the equipment control panel for any issues, such as the parameters of the feeder, and whether the suction and discharge times are correct. If there is a problem here, it may not be able to suction materials normally, and should be changed and resolved promptly.
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, leading to 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 check if there is too much dust or any clumping on the filter element. Such issues could lead to improper suction. If this problem occurs, simply clean it with compressed air.
