It involves a fully automatic filter screen replacement device for a sheet extruder without shutting down, which includes a connection control module and a roll shaped filter screen,
The above-mentioned connection control module is set between the extruder screw and the material pipe of the extruder. The connection control module is equipped with a feeding safety channel that communicates between the extruder screw and the material pipe. The connection control module also sets a filter safety channel that surrounds the connection control module and is vertically connected to the feeding safety channel. The above-mentioned roll shaped filter is set at one end of the filter safety channel, and the top of the roll shaped filter enters from the inlet end of the filter safety channel and exits from the outlet end on the other side of the filter safety channel
A first heating zone is set at the position of the feeding safety channel that matches the internal connection control module mentioned above; A second heating zone is set inside the connection control module from the feeding safety channel to the inlet position of the connection control module. The heating devices in the first and second heating zones are operated by the control board, completing the automatic replacement of the filter screen without shutting down, ensuring the continuity of the extruder operation, reducing energy consumption damage, and improving work efficiency
