Embodiment
As shown in figure 1, the utility model is mainly made up of mesh changer main body 1 and hydraulic power unit two parts.
Mesh changer main body 1 includes preceding main board 4, rear main board and draping plate, and preceding main board 4 and rear main board are relative to be set
Put, draping plate is arranged between preceding main board 4 and rear main board in institute's clip space.Preceding main board 4 is connected with the head of extruder,
Main board is connected with the machine barrel discharge end of extruder afterwards.Charging aperture is offered in the center position of preceding main board 4, melt is used as
Material enters the entrance of mesh changer main body, offers discharging opening 5 in the center position of rear main board, is used as mesh changer main body
Material outlet.Melt material from machine barrel first flows into the charging aperture of rear main board, through on draping plate screen pack 9 filter after from
The discharging opening 5 of preceding main board 4 flows to head.Cast copper heating plate 7, upper cast copper heating are provided with the top of mesh changer main body 1
Plate 7 is covered in the top of preceding main board 4, draping plate and rear main board；Lower cast copper heating is provided with the bottom of mesh changer main body 1
Plate 8, lower cast copper heating plate 8 is covered in the bottom of preceding main board 4, draping plate and rear main board.Upper cast copper heating plate 7 and lower cast copper
Heating plate 8 realizes the equal of the screen pack 9 on exchange web plate by the guide plate uniformly transfer heat to front and rear main board and draping plate
