Manual screen changer
For those who specialize in plastic extrusion, the screen changer is an indispensable filtering component on the production line! Today we will talk about manual screen changers and entry-level filtering devices.
Basic Structure
Mainly composed of body, skateboard, sealing component, mesh plate, and filter screen
Working Principle
During production, the melt passes through a filter screen to remove impurities and coke from the material.
After the filter becomes clogged and the pressure increases, manually push the skateboard to slide out the dirty mesh station, and the backup new mesh station will enter the flow channel to complete the mesh replacement operation.
Core Advantages
Simple structure, low failure rate, and easy maintenance
No need for hydraulic station, lower equipment investment cost
Compact size, flexible installation and adaptation, making it easy to renovate old production lines
Easy to learn operation, workers can quickly get started
Limitations should also be noted
Changing the network requires manual operation and cannot be done without stopping the machine
Suitable for low to medium capacity production lines, not suitable for 24-hour uninterrupted high load production
Application Scenarios
Small granulation line | Extrusion test line | Plate, pipe, and profile extrusion
Suitable for PE, PP, modified materials, ordinary elastomers and other materials
Suitable for factories with limited budget, low production capacity, and weak requirements for continuous production
The advantage of manual screen changers lies in their cost-effectiveness. To pursue continuous production without stopping, dual station hydraulic screen changers should be considered.
